****** Nightmares of dust and shadows ******
by FelliSkelli
Summary
     Sans is tired, a moment away from simply giving up and Falling Down;
     but then he finds out that his beloved little brother remembers their
     father Gaster; and not only that, but reciprocates Sans' love! He'd
     never been so happy! But it is not so easy, because Papyrus has
     reoccurring nightmares about the tortuous experiments their father
     inflicted upon him as a child, and he keeps waking up to find holes
     in his hands...Gaster just can't leave well enough alone, and he has
     plans for his sons...
Notes
     Ok, so this fic is based off of an ongoing RP i have going on with
     @Edgyguardsman on Tumblr, so I am sharing credit with them, they are
     amazing, check out their blog. Also, check out mine. XD Unless my
     blog is what brought you here. Even so!
     Edgy is playing Papyrus and Gaster, I am Sans, we both have done some
     work with Grillby when he shows up. This is super angsty, super
     fluffy, and gets super, DUPER dark, with lots of sin. I hope you all
     enjoy! I've fleshed out the scenes, changed some of the narration to
     better fit being from Sans' perspective instead of both, and added
     some background information to foreshadow some stuff and just pad
     things out a little, but all the dialog (except for a few tweaks) are
     as is from the RP, so all of Papyrus' and Gaster's dialog belong to
     Edgy!
***** Sans and Papyrus have a chat *****
Sans Serif was so fucking tired of the almost unbearably monochromatic life of
the Underground. The sullen red of dead leaves, the dingy white of snow, the
lifeless gray of dust, the bleak black of despair. Those colors were the only
hues that appeared in the Snowdin side of the Underground. And the other areas
were not any better, Waterfall was predominantly a sickly yellowish-blue and
Hotlands a lamberent red, but otherwise just as dreary. The only colors anyone
ever wore was red, black, gray and rarely some white. No one had any visible
magic aside from the red of determination, it was not safe to appear with any
other color. It was just so tiring and depressing, and he did not need the
help; his life (his existence) was more than depressing and tiring in its own
right.
Of course he did not exactly try to subvert the monochromatic pattern in any
way, he himself wore black and red exclusively. He wore an overly large red t-
shirt that hung on his gaunt skeletal form (he was a skeleton after all, but
due to lack of proper nutrition, smoking addiction, lack of restful sleep, and
his near crippling depression he was faded and wane even for a skeleton), baggy
black basketball shorts that hung halfway down his shins, a large and baggy
black hoody lined in off-white fur that he used to hide his form, and a pair of
red socks and running shoes.
And his little brother was the same, wearing black pants and battle body with
red boots, gloves, belt and and a scarf that doubled as a cape. But Papyrus was
suited to those aggressive colors, they gave him an intimidating air that he
never failed to turn to his advantage. Of course, the fact that he was second-
in-command under Undyne of the Royal Guard was also a great source of potential
intimidation, especially as Papyrus took his duties incredibly seriously.
And he took his brother’s failures to fulfil his own duties just as seriously.
Red had been supposed to be on Sentry Duty near the Ruins today.
But although he had gotten up at his brother’s furious demand this morning, and
gotten ready for work (not that it required more than getting dressed to get
‘ready’), he had not been able to summon the energy to leave the house, he’d
simply waited for Papyrus to leave for his patrol and then collapsed on the
couch.
And that was where he still was, eight hours later.
He was slouched on the worn red couch with no effort to maintain proper
posture, he could care less that his spine was beginning to complain at the odd
position he had laid in for the last hour, or that his joints were starting to
stiffen. He did not notice the pain, he was numb to it. He had the TV on but
was not bothering to even try to pay attention, it was just white noise to him
as he sat there; he was just trying to be as blank as possible, hoping that
maybe he would eventually fall asleep.
Last night he had hardly slept at all, his nightmares had been worse than
usual, and that made him nervous. There had been no resets for a long time, but
that could change at any moment. And that terrified him more than anything else
ever could; not his brother, not the dogs, not even Undyne or Asgore. Just
thinking that a reset may be about to occur made him shiver so hard his bones
rattled and he barely even flinched when his brother berated him, he could
hardly even function. It just brought invasive thoughts of self-hatred, panic,
hopelessness.
Why couldn’t it just stop?! He was so tired, always so tired...reliving the
same days, over and over and over again, nothing ever changing, nothing he did
ever mattering...he’d lived through years worth of resets in the past, and
after having almost a year free of resets, he’d almost hoped that they would
never happen again. The thought that they may begin again was more than he
could bear.
If it was not for his beloved little brother, Papyrus, he would have found some
way to kill himself long ago.
Papy was all he had, even if his brother hated him.
It made sense, Sans hated himself too.
He was just such a monumental fuck up.
Even if he had somehow summoned the energy to go to his sentry station today,
he would likely have just fallen asleep there anyways. Even though it was
incredibly dangerous to put himself in such a vulnerable position, he just
usually felt so tired, all the time. He figured he was probably on the brink of
Falling Down, just held together by 1 HOPE.
He had been caught sleeping by Papyrus more times than he could count, and he
was pretty sure that one day Papyrus would just give up on him entirely. Sans
sometimes wondered how far he could push his little brother.
As if hearing his thoughts, that was when Papyrus came home angry as usual. He
slammed open the door and and let it bang off the wall and bounce close with
another slam, as he came in on a warpath, looking for the smaller skeleton.
“SANS!? SANS WHY WERE YOU NOT AT YOUR POST TODAY!?” He stormed to the couch. “I
DID NOT BUST MY ASS TO GET YOU THAT JOB JUST SO YOU COULD SIT HERE AND BE LAZY
ALL DAY!”

Sans had not even notice his brother for a moment, even considering Papyrus’
usual volume (which was always turned to max) and the door slamming barely
fazed him; but when his brother stood over him he finally realized that his
brother was home and let his eyelights rekindle and he tried to grin up at
Papyrus but it came out crooked.

“uh, hey boss, i was just, bone-tired, you know?” he greeted with a lazy grin,
not quite meeting his little brother’s eyes.
Papyrus did not look amused in the slightest, although he had once appreciated
Sans puns. His eyes blazed a dark crimson, his teeth parted in a snarl as he
grabbed Sans by the collar and ripped him from the couch and onto the floor. “I
AM SO DONE WITH YOUR SHIT! YOU’RE SUCH A FUCKING CHILD AND I AM THE ONE WHO HAS
TO RAISE YOU! I AM YOUR FUCKING YOUNGER BROTHER! YOU CAN’T COOK, YOU CAN’T
CLEAN, YOU WON’T GO TO WORK, WHAT ARE YOU EVEN GOOD FOR!?” He kicked him hard
in the side.

 Sans was still a little out of it so barely reacted when he was yanked off the
couch except for a widening of his eyes, but his hands were still limp at his
sides and when he was thrown to the floor he did not even try to break his fall
or dodge his brother’s kick. He hissed in pain, but embraced it. It was what he
deserved, his brother was right, as always. He was just worthless.
A waste of space.
An anchor to his brother’s career.
A blight on his life.

 He deserved whatever his brother did to him.
He looked up at his brother with a weak smile, not even trying to get up.
“sorry, boss…it, it  just doesn’t really matter when it might all just re-” he
realized what he was about to say and froze, reaching up to wrap his phalanges
tightly around his collar and ducking his head. “really not matter in the end…”
he covered for his misstep, curling up around his injured ribs.

Papyrus kicked him square in the face this time, hard enough to at least crack
something.
 Sans tried in vain to raise his hands to protect his face, but his brother was
much quicker than he with anger fueling his motions. That and Sans lack of
proper sleep, proper food…Sans’ head snapped back and he made a choked whine of
pain and almost blacked out. This hurt a lot more than the injured ribs. He
fought not to cry, that would just make his brother even angrier. Any more and
he might just forget to hold back. He might dust him.
“Fucking waste of my time… And pick up your damn socks!” Papyrus snarled with
impatience, as he stormed off to the kitchen with a stiff spine and clenched
fists to make dinner for himself and only himself. He pulled out a pot and a
box of spaghetti and started cooking, ignoring his brother from the other room.
Sans made a low groan of pain as he shivered slightly. He just lay there
allowing his pain to wash over him, his left eye throbbing. He wondered if the
small crack over his eye-socket had grown. Maybe it would be as cool as his
brother’s. He laughed weakly.

He was so tired.

He rolled over weakly to watch his brother stalk into the kitchen and heard the
sounds of him preparing spaghetti. He doubted he would be invited to dinner. He
lay silent for a moment before levering himself painful upright and pausing for
a moment before getting to his feet. His left arm wrapped supportively around
his ribs and his right hand absently ran over the side of his face feeling for
new cracks. He felt a trickle of warm marrow leak down the side of his face.

Papyrus had been super pissed this time, he realized as he ran his phalanges
gently over the small crack on his cheekbone, right below his left eye socket.
Papyrus hadn’t held back at all, if he had put much more force behind the kick
he could have dusted him; and he usually controlled himself much more.

Maybe he was done with dealing with Sans’ shit, Sans knew he was tired of it
himself.

He looked tiredly at the corner and saw his sock, he guessed that prank was a
little old. He walked slowly towards the discarded article of clothing that
offended Papyrus so greatly and picked it up manually, too tired to lift it
with magic. He stuffed it in his pocket and turned to look at the door.

 He wanted a drink, but he was in no mood for trying to avoid Grillby’s
advances. The fierce purple imp had become more and more aggressive of late.
After deciding that he would no longer accept Sans gold (and taking his tab in
sexual favors instead) he had started pursuing Sans almost obsessively. Sans
was starting to actually feel intimidated. Not that he did not enjoy the sex,
Grillby was literally and figuratively incredibly hot. But, well, neither of
them loved one another, and when a monster had sex their souls connected no
matter how involved they were, and Sans was starting to feel ill from the
affectionless intimacy.
And that was not even mentioning the sexual favors that the dog guards expected
from him as the lowest ‘dog’ in the pack; he had no choice, but at least when
he kept them happy and satisfied they kept the other Snowdin residents from
bothering him, which was more than Papyrus ever did. Of course that was not
counting Doggo’s growing obsession with him; ever since he’d caught Sans at his
station during his last Heat, and taken care of it for Sans (who’d only made
token protests if he was being completely honest), he’d been acting like he
owned Sans.
Now that Sans was thinking about it, it was during the Heat before that, that
Grillby had started his sexual advances.
Monsters went into heat at different rates depending on species, but
considering how violent it was down here, heats had become rarer, because it
put the monster in incredibly vulnerable positions, displayed weakness, and
just made the monster the hugest of targets. Also the environment was in no way
supportive of a monster trying to bear young. So Sans had no idea why he had
started going into heat almost once every other month for the last half year.
Sans was such a shameless slut while in heat...the first time he had just hid
in his room the entire week he went through his heat unassisted, it was the
most miserable time of his life, and Papyrus had been furious with him. And
while he had masturbated desperately, frantic for relief, mindlessly rutting
against his pillow, or his hand, crying with need; he had imagined that it was
Papy helping him...
He was so sick.
And he was also so tired. While considering his options he fell asleep while
standing in the corner, feeling the slightest bit pleased with having at least
followed one command of his brother’s.
---
Papyrus cooked his dinner with a single minded intensity, almost violently
throwing the ingredients together as he fumed. But he could not sustain his
understandable anger, his brother was a worthless piece of shit who could not
accomplish anything on his own, but cooking always calmed him down, so by the
time he had finished the sauce and mixed in the noodles he was in a
considerably better mood.
He took his plate to the table and just happened to glance over to the corner
and saw his brother, asleep. The lazy whelp. He placed his plate down a little
more violently than he had intended and started to approach his brother.
That was when he noticed that Sans had actually picked up the sock. He sneered
while approaching the sleeping form of his big brother. At least he followed
that order for once, it was about damn time. That was when he saw Sans’ face,
and the newest crack.. He really did a number on him this time.
He felt a twinge of guilt that he tried to ignore, he turned away, tried to
ignore his brother, but he couldn’t.
Sans had been good to him when he was young, protected him. Raised him. So he
found himself picking up his big brother and carrying him up to his room.
---

 “papy-!” Sans gasped as he shot upright, blinking slowly to find himself
sitting in his own bed, his blanket pooled in his lap. He looked to his side
and saw that there was an ice-pack next to him, and raising a hand to his face
he felt the chilled bone.
 It took him a long time to get over his disorientation, he did not usually
wake up somewhere other than where he had fallen asleep, and the only way the
ice pack and spaghetti could have come to be here was if Papyrus had brought to
food here, had brought him here.

 As if he actually  cared . Sans eyes teared up as he reached for the plate,
his soul pulsing with a sudden rush of love.
Papyrus could be so thoughtful on some occasions. It was so much more than he
deserved, that was why Sans loved him so much, Papyrus was so good, so much
better than every monster in the Underground. He took the plate in trembling
hands, the sight of so much food almost too much for him at first, he had eaten
so little recently. But his brother’s thoughtfulness pinged at his guilt.
He ate it all, enjoying every bite, trying not to cry, it tasted delicious,
Papyrus had gotten better.
Sliding out from under his blankets he got out of bed and crept downstairs, he
did not know what time it was and did not want to disturb his brother. He took
his plate into the kitchen for once instead of letting it mold in his room.
---

 Papyrus was eating silently while on the couch, his thoughts spinning. TV off,
just him and his thoughts which were always a dangerous place to be. He was
angry so much of the time, sometimes he worried about how angry he was, but so
much made him angry.
Being Second-in-command over a bunch of idiots. The idiots in Snowdin. The
Rules that Asgore wanted them to inforce. Sans.
Sans use to be the mentally older more responsible one when they were children.
Sans had been a teenager when Papyrus was born, and sometimes Papyrus wondered
what had happened to him, what their father had done to him before he’d made
him. Sans had been more of a father than their own father ever had. He had
protected him from their father, taught him how to protect himself and fight,
pretty much raised him when Gaster wouldn’t. Gaster had been cruel with his
experimentations, not caring how much pain they were in, only wanting his work
to have meaning, not even explaining anything although Papyrus had always had a
feeling that Sans had known more than he had ever shared with his little
brother.
He couldn’t understand, but he remembered that Sans had never been afraid of
their father, he had been obedient, and willing, unless Papyrus was involved;
that was the only time he fought Gaster. He’d been fiercely protective, and had
suffered for it.
And then Gaster had left, vanished, and Sans had ran with Papyrus and they had
wound up in Snowdin. And although life Underground was dangerous, Sans had
still kept control, took care of him.
Papyrus couldn’t understand what changed. A few years ago he just stopped and
became like a child again... Sleeping all day, not leaving the house unless
Papyrus forced him to, becoming completely dependant on Papyrus. It felt like
now it was his turn to raise his older brother but that was not okay. Papyrus
had much more on his plate than Sans thought.
But still, after all Sans had done for him when he was a child, how could he
resent him so much? His stomach was filled with guilt.
He heard Sans coming down the stairs. He didn’t look at him at all but he
quietly asked, “How’s your face..?”
----

 Sans had not even noticed Papyrus sitting on the couch, the taller skeleton
was incredible stealthy when not being his normal flamboyant self. He was
startled by his brother’s presence and jumped slightly, almost dropping the
plate. He stared at his brother with wide sockets, trying to decide the best
way to answer.
He had not known Papy to stay up so late, he was always so punctual, and he
should have been asleep right now, resting for duty tomorrow. Anything out of
the ordinary made Sans nervous. So nervous that for a moment he did not
understand that his brother was addressing him.

 “well boss, you know you keep saying i have a thick skull…” he chuckled weakly
and rubbed his face lightly, trying not to wince. He felt some dust crumbled
off beneath his phalange tips. He shivered with disgust and dropped his eyes to
the ground.
He glanced at his brother and saw that Papyrus looked…tired? He dropped his
eyes to the ground feeling guilty, it was his fault of course. Papyrus had not
even turned to look at him, he hardly did nowadays, it was almost as if he was
ashamed of Sans...not that that was unexpected.
“hurts a bit, but i deserved it. ’ll be fine.” He muttered honestly. He turned
to take the plate into the kitchen.

 Papyrus followed Sans to the kitchen with his own plate.
“Let me see it…” He touched his face with his ungloved hand. “I’m… Sorry…” He
looked away, His voice still unusually soft. Those were words he hadn’t uttered
since he was a child. He carefully pulled away and leaned against the counter.
“Did the ice pack help at all?”

He had not expected his brother to follow him, especially not with…concern? He
could not help himself from leaning into his brother’s touch, and his eyes
began to close before flying open in shock when he heard words of apology.
He craned his neck back to stare up at Papyrus, at a loss for words
momentarily.

His brother was acting incredibly strange tonight. Feeding him, showing
concern...touching him. He blushed slightly and dropped his eyes to the floor
as he felt another rush of emotion, a deeper well of affection. He stepped back
a pace and peeked up at his brother.

 “are…you ok boss? you…don’t usually…care. i mean, like i said, i’m fine,
i’ve…had worse. you know i don’t break that easily…i mean….that is the one
thing i’m good for right? i don’t mind you taking your anger out on me…” he
dropped his eyes and finished putting the plate in the sink. “i know i’m
worthless for anything else…”
Papyrus stared at him in shock for a moment, eyes wide and he was quiet for
several long moments. And Sans had not had such maintained eye contact with him
for what felt like months and he felt the urge to blush, he ducked his head; he
did not want any awkward questions.

 Papyrus turned away then with a slight scowl. “I’M FINE.” He didn’t sound fine
though, his voice trembled slightly, and Sans found himself following his
brother with concern.
 “JUST...FINE.” Papyrus was starting to sound a little embarrassed and Sans saw
a slight pinkish tinge to his cheeks. He looked sad, not angry. He stormed off
to the other room and sat down. He stared down at the floor lost in thought
again.

Sans stood watching his brother stomp back into the living room, his shoulder
slumped, his eyes dim. His brother was acting really, really strange. Sans
stood wringing his hands for a moment before slowly stepping into the doorway
and watching his brother on the couch for several moments.

Papyrus needed him.

Feeling nervous Sans walked slowly towards the couch and sat silently next to
his little brother.
 “how was training today?” he asked softly, trying to find a topic that would
bring his brother to a happier state of mind. His brother usually enjoyed
bragging about his training, it got him so excited and pumped up and Sans
always thought Papyrus looked the most attractive when he was being flamboyant.

Attractive. He felt his sins crawl up his back. He had been lusting for his
little brother for years, in love with him. Wanting to be with him. He was so
sick.

“TRAINING? OH IT WAS JUST FINE, EVERYTHING I EVER WANTED! AS USUAL FOR THE
GREAT AND TERRIFIED PAPYRUS, I MADE SURE THAT PATROL WENT AS SMOOTHLY AS EVER
AND BROKE UP A PITIFUL REBELLION IN WATERFALL” Papyrus exclaimed with some of
his usual boisterous pride, but his pleased grin trembled at the corners and
did not reach his eye sockets. His smile faded before returning weakly. “We…
Passed dad's old lab…” He trailed off getting lost in deep thought again. His
eye sockets started watering.

 Sans almost could not believe his eyes, was Papyrus….crying? Papyrus NEVER
cried. Not since they had moved to Snowdin, and that was years ago. Decades.
And...how did he know about Gaster? HOW? Because of the Core flux in tandem
with the recoil of the Device for seeing into the Void which had scattered
Gaster through time and space no one remembered Gaster but Sans. Because he had
been there. His father’s favorite lab assistant.
When he wasn’t his favorite lab rat.
His soul clenched as he thought about his father, and he resisted the urge to
clutch his chest. Gaster had been a horrible father. The worst. But Sans had
loved him beyond thought, been loyal, even when all Gaster had done was hurt
him. But the true light of his life had been Papy, he’d adored him from day
one, and he had only ever been angry when his father tried to experiment on
Papyrus. He had not always been able to protect Papyrus, his father had done
some horrible things to him, things that still haunted Sans with guilt for not
preventing to this day. But he’d still managed to keep most of their father’s
attention on him…
He had been jealous if their father focused on Papyrus too much.
He felt conflicted and his mind was in a whirl.
He focused on the fact that no one should remember Gaster, including Papyrus.

“b-boss!” He tried figure out what to do with his hands, flailing slightly
before deciding to turn to face Papyrus and wrapped his arms around the taller
skeleton’s shoulders and pulling him into a soft embrace.

“boss…you…remember gaster?” he asked softly, desperately wishing he had not
misheard Papyrus. If at least one other person remembered...if he was not alone
with that knowledge like he was with the resets and alternate universes...

 “AM I NOT SUPPOSED TO REMEMBER HIM? HOW COULD I POSSIBLY FORGET?!” Papyrus
started, sounding horrified before his voice dropped again, his eyes drifting
over Sans’ face. “He experimented on both of us! You protected me from him… I
use to look up to you… You pretty much raised me but now… I don’t know what
happened to you…” Papyrus asked, his voice low and trembling ever so slightly;
wiped away his tears. “You’re not suppose to see me like this…”
Sans had never heard his brother sound so weak and lost. He clutched his skull
in his hands for a single moment before coming to the decision to comfort his
brother, worry about how it happened later.
Sans leaned over and shyly pressed a gentle skeleton-kiss to Papyrus’ cheek and
nuzzled him lightly. Despite the fact that it should not be possible, despite
the fact that it was far from a happy memory, someone else remembering Gaster
was a huge relief. He could not help the sudden euphoria that had him feeling
affectionate.

“it’s ok boss…i won’t tell anyone…” Sans teased lightly, he saw a small blush
tinge Papyru’s cheekbones and he returned the embrace gently, hesitatingly.
Sans tightened his embrace slightly before pulling away.

“and…well, do you remember how…gaster….vanished? because he…well, scattered
himself across time and space. no-one except me remembered him…until, how long
have you remembered him?” He scratched the side of his face thoughtfully and
suddenly realized how touchy-feely he had been with Papyrus and worried that he
was making things worse and started to get up.

“No I… I actually don’t..” He looked down with a sad expression on his face. “I
only remember the torture…. And you…” He looked up confused. “HOW LONG? WELL,
SINCE WE MOVED HERE I GUESS. I...I GUESS A LOT OF MY MEMORIES ARE FUZZY BUT
I’VE REMEMBERED FOR A LONG TIME...I JUST DON’T TALK ABOUT HIM, HOW DO YOU ‘NOT
REMEMBER’? I’D LIKE TO FORGET…” He frowned more when Sans let go. That’s okay.
He missed the comfort though…

Sans saw his brother’s face, he was practically pouting, like when he had been
a baby-bones. Sans sat back down and leaned against his brother, closing his
eyes and thinking about Gaster.

He was so tired.

“i don’t know bro-boss. i just never forgot. that is…one of the reasons i…am so
messed up. i just can’t…i get nightmares.” I closed his eyes. He was so tired.
“among other things i know that…did…you know about…timelines?” he did not think
Papyrus would know what he was talking about, but if there was even the
smallest possibility, that he was not alone with this horrible knowledge…

 “TIME LINES….?” Papyrus looked over at him confused. He must have seen the
desperation on Sans’ face because he looked guiltily away, as if he felt that
it was his fault that he did not know anything about what Sans was asking.
 “NO….I DON’T...I’M SORRY…”
Sans felt his shoulders slump as weariness overtook him. He’d lived alone with
the weight of knowledge gained from glimpsing the void for decades, and he’d
had the briefest hope to have someone share the burden only to have it dashed.
He just about collapsed into tears.

“I DID NOT KNOW YOU HAD NIGHTMARES ABOUT DAD…” Papyrus said a little gruffly as
he changed the subject. “I DO TOO SOMETIMES… I never showed it… I can’t show
weakness…. Every time I showed weakness with him he made the pain worse on
purpose…. I… I’m scared Sans…. I’m scared and I shouldn’t be but I’m scared to
even be talking to you like this…. I just can’t be weak..” Papyrus’ voice
dropped to a whisper as he admitted to his terrible weakness, and Sans’ soul
felt warm with the fact that his brother was confiding in him, trusted him with
this knowledge. But at the same time he felt despair in his mind.

 Sans tried to not show how his soul fell at Papyrus’ words, he knew that
Papyrus could not know, but he had hoped so much….so much….that he was not
alone with the resets. He tried to not tremble as he listened to his brother.
He focused on his brother’s sorrow to ignore his.
He had not know Papyrus was so depressed. He wrapped his arms around Papyrus
again and nuzzled his cheek softly.

“you are the strongest monster i know boss. and…gaster is gone. gone and not
coming back. he can’t hurt you. and even if he did somehow come back, i would
not let him touch you.” His last comment came out much fiercer than he had
intended and he flushed embarrassed and ducked his head.

Papyrus smiled a bit at that. “Just like old times?” He chuckled a little then
sighed. “I can take care of myself now… But… That makes me feel safer..” He
smiled at his kind words. “I DON’T THINK WE’VE TALKED LIKE THIS SINCE WE WERE
CHILDREN. IT’S STRANGE, IT FEELS A LITTLE WRONG BUT IT MAKES ME...HAPPY…?” He
sounded as though he was confused by his emotions.

Sans found himself smiling despite himself and hugging his brother tighter.

 “i’ve missed times like this, papyrus….” he murmured sleepily. “i…” love
you….he did not say. he did not know how Papyrus would take that, it was risky
enough using his name. He coughed slightly and continued, hoping Papyrus did
not notice how red his face was. “nothing wrong with it, boss. i like making
you happy.” He realized how that sounded and flushed redder, hiding his face.
“Papyrus.. Papyrus is fine..” He smiled at his older brother. “At least when
it’s just the two of us.” He reassured. A light blush covered his cheeks when
he saw how flustered Sans was. He chuckled a bit. “YOU LIKE MAKING ME HAPPY?
COULD HAVE SWORN YOU TOLD ME YOU WISHED I WAS DEAD TWO DAYS AGO….” He leaned
his head on his shoulder. “I DON’T UNDERSTAND YOU SOMETIMES, BUT I GUESS I AM
NO BETTER..”

Sans flushed even brighter when Papyrus laid his head on his shoulder and
fought the urge to lean in closer to his brother’s warmth. He did nuzzle
Papyrus slightly though, his soul beginning to glow with happiness. He and
Papyrus had not been so close in years. He hoped this was not a dream, if he
woke up from this he might just actually follow through with his plan to dust
himself.

 “it’s okay papyrus…i don’t really understand myself either.” Sans sighed with
self-deprecation.
He glanced up to see Papyrus blushing. Before Sans realized what was happening
his little brother suddenly leaned forward to clack his teeth clumsily against
Sans’ cheek in a skeleton-kiss. Once Papyrus realized what he had done he
pulled back with a brighter blush.

“I LOVE YOU…. A-AS A BROTHER! YES YOU’RE MY FAVORITE BROTHER!” He blushed
embarrassed as he caught the words from his mouth. “….I’m showing weakness
aren’t I…..”

Sans  jumped slightly turning to face startled eyes towards his brother, his
eye lights flickered into the shape of hearts for brief moment before returning
to usual. Without really even stopping to think he leaned forward and pressed
his mouth softly to Papyrus’ before pulling back slowly, his face entirely red
as he suddenly realized the line he had crossed.
***** Brotherly love *****
Chapter Notes
     This chapter is basically entirely smut with a little bit of angst,
     lots of fluff. Enjoy it my fellow Sinners!
“s-sorry b-boss! i’m sorry, i’m sorry” Sans yelped frantically as he tried to
pull away and fell of the couch with a thump. He did not want to see the
disgust on his brother’s face. He was such a twisted, filthy, horrible monster.
How dare he try to take advantage of his brother…he pulled his knees to his
chest and started to claw at his face as he tried to figure out what he was
doing.
Before he could do himself any damage his wrists were grabbed in the firm grip
of his brother’s hands as Papyrus pulled his hands away from his face, looking
up Sans saw that Papyrus was blushing intensely as he stared a little glassy
eyed at Sans as though he needed a moment to process what just happened. After
a moment Papyrus smirked and yanked Sans up to his knees before dropping his
wrists.
Sans was so shocked he didn’t resist.
Papyrus grabbed his chin and brought his face up. “I said Papyrus was fine..”
He pressed his mouth against his brother’s and held it for as long as he could.
He slowly wrapped his arms around Sans, pulling him closer.
Sans gave a small gasp of shock before allowing his brother control, and when
his brother pulled him closer he eagerly crawled back into Papyrus’ lap,
straddling his hips and whining needfully in the back of his throat as he
absently began to rock his pelvis against his brother’s. He had not known how
much he’d wanted this, but now that Papyrus was touching him he did not want
him to stop. He conjured a tongue with his magic and once Papyrus pulled back
the slightest bit he lapped at his brother’s teeth.
“pa-p-apyrus…” he panted with a flushed face, his eye lights dilated.
A deep red blush covered Papyrus’ face as he kissed his brother. He followed
and summoned a tongue as well. “MY SANS…” He purred as he pried Sans’ jaw open
with his tongue. He wanted this, he needed this. All of his worries, memories,
need to keep a strong image, all worries left him as all of his thoughts were
on his brother. He thrust his tongue into his brother’s mouth, tasting his
tongue, laving over the roof of his mouth, the back of his teeth, dominating
him.
Sans gave a small moan as he allowed his brother to dominate him and leaned in
closer to Papyrus, tilting his head back. His brother’s possessive claim on him
had him trembling in delight and he gave a pleased moan and wrapped his arms
around his brother’s shoulders. “yours, always yours…” he breathed happily
before delving back into the kiss, sucking on his brother’s tongue.
Papyrus smirked possessively at the confirmation. Yes, he wanted his brother
all for himself. He shuddered when sans began sucking on his tongue. He moaned
in pleasure, pulling sans closer to him and grinding him. There was a red
glowing coming from between his legs as a bulge grew in his pants that he
grinded up into Sans.
Sans started to chuckle when he felt his brother shudder against him but his
sound of amusement became a shuddering moan as Papyrus ground up into him and
he rocked his hips back a little desperately, his magic beginning to focus and
build at his pelvis. he wanted this, he wanted it so much. Papyrus made him so
hot, he already felt wet.
He shifted on Papyrus’ lap, trying to ignore the growing lust he was feeling,
he was already corrupting his baby brother enough…
Papyrus smirked down at his big brother. “MY SANS…” He pressed his mouth
against Sans’ neck bone. “I BELIEVE YOU’RE HIDING SOMETHING FROM ME.” He
teased. He had noticed the red arousal  glowing through Sans’ pants. His tongue
slid out of his mouth and began lapping the side of Sans’ neck. “You’re mine… I
don’t want anyone else to have you...Understood?” He purred, his voice dropping
low and his tone sent heat pooling quicker to Sans’ loins.
Sans squeaked in embarrassment and lust began to fog his mind at his brother’s
possessive words. His magic began to coalescence into a more tangible form at
the base of his pelvis and due to his submission to his brother his magic
formed a dripping vagina rather than his usual cock that he would form when
pleasuring himself. He bucked his hips into his brother’s pelvis with a mewling
cry and hid his face in his brother’s shoulder.
“pa-papyrus…” he whined, he had not ever imagined that his brother would tease
him like this, and it was turning him on so much, even though it was
embarrassing.
Papyrus chuckled, amused by his brothers desperate movements. He grabbed his
brother's chin and forced him to look at him. “You know I’ll let you have me if
you just beg.” He smirked, his eye light glowing a bright thirsty red. “Or if
not I’ll just tease you more until you do..” He slowly slipped his hand up his
shirt and fondled his rib cage.
Sans flushed an even brighter red as he met his brother’s eyes, and for a
moment he felt like begging might be beyond him, until he felt his brother run
teasing phalanges over his ribs. He shuddered at his brother’s ministrations as
his pride fell away.
“papyrus, please…i need you….” he begged shamelessly as he bucked against his
brother again wantonly. He leaned forward to lick his tongue up Papyrus’ neck.
Papyrus grinned in pleasure. “Very good Sans.” He started to unbuckle his
pants. “Undress yourself.” He gave a quick kiss to his brother before he
undressed.
His erection sprung free, it was bigger than what Sans thought it would be.
“Well...I’m waiting.”
Sans stared hungrily down at his brother’s girth and moaned in want as he
quickly scrambled off his brother’s lap and practically tore his clothing off.
Underneath his layers he was surprisingly delicate and most of his bones were
scarred or scratched. He froze indecisively for a moment, embarrassed by his
body before gazing almost shyly at his brother.
Papyrus ran his eyes slowly over him, from his crown to his toes, his eye
lights dimming with lust and his teeth widening into a hungry growl; he
obviously liked what he saw, and considering he was a warrior he might even
find Sans’ scars arousing, which had never occurred to Sans before. He dropped
his eyes, flushing under his brother’s scrutiny, his pussy began to drip his
arousal down his femurs.
Papyrus chuckled, a deep sound that had Sans trembling. “FEELING SUBMISSIVE I
SEE?” He purred as he smirked and he placed his hands on Sans’ hips, pulling
him closer until he stood between his spread legs. He then let a hand wander
over Sans’ pelvis, teasingly, before pressing rougher as he began to drift
towards Sans’ opening. Sans gasped and arched his spine, trying to rock his
pussy into his brother’s hands, wanting his fingers in him, wanting to be
filled.
He examined his brother with half-lidded eyes, focusing on his brother’s cock,
it was huge. He licked his teeth hungrily and moaned. He wanted to be filled,
but more than that, he wanted to taste his brother. Wanted him in his mouth.
All it took was that thought to cross his mind before he carefully grabbed
Papyrus’ hand in his before he dropped to his knees between his brother’s
spread femurs. He released his brother’s hand and placed his own on his
brother’s hips to keep his balance as he bent down to engulf his brother’s
delicious looking cock as though he were starving for it, he all but inhaled
the length.
Papyrus made a shocked gasp as Sans wrapped his tongue around him, before
pulling the cock into his mouth, conjuring a throat to swallow around the
dripping head of Papyrus’ arousal, trying to take as much of Papyrus in his
mouth as he could. He made a mewl of pleasure, Papyrus’ magic tasted so good,
it was so hot and heavy in his mouth. He rolled his eye lights up to look at
his brother’s face, seeing him red faced and panting, his own eye lights rolled
back.
Papyrus placed his hands hesitatingly on Sans’ skull, holding him, pulling him
closer. Sans gagged slightly before swallowing, he made a chuff of pleasure
when he heard Papyrus swearing underneath his breath. Papyrus began to rock his
hips, thrusting his length deeper down Sans’ throat almost roughly, and then
with a low growl he began to fuck Sans’ face while drool and precrum dripped
out the corners of his gaping jaw. Sans hummed happily, enjoying the feeling of
being used for Papyrus’ pleasure.
He was feeling so wet, his pussy was soaked and his arousal was forming a
puddle on the floor beneath him. He wanted this cock in his pussy, and he
wanted it now. He lifted his hands from his brother’s pelvis and pushed on his
wrists lightly, and although Papyrus tightened his grip and thrusted a couple
more times he eventually relented with a low drawn out groan.
Sans slowly pulled himself off of his brother’s cock, a string of saliva and
precum attached from the tip to his tongue and he gave his brother a lewd smirk
as he slowly rose back to his feet, displaying his soaked pussy with a purr,
“i’d love to swallow your cum brother, but this needs attention…”
Papyrus was still gasping and panting softly, one hand clamped hard around his
cock and he was sweating, but he slowly regained control as he breathed deeply,
and then he smirked and leaned further back, eyeing his big brother with
admiration.
“I actually wasn’t expecting that, Sans, it was a pleasant surprise.” Papyrus
murmured more to himself than to Sans as he dropped his eyes from Sans tongue
to examine his pelvis, he peered at Sans’ vagina curiously, trailing his
fingers over the puffy lips of his vulva.
Sans did not know why, but he suddenly felt nervous and looked to the side with
a small scowl (more like a pout) and tried to cover himself with his arms.
“s-shut up…” he growled, embarrassed. Papyrus was still teasing him, and
although he was starting to like being taunted and embarrassed, enjoyed being
dominated and wanted to demeaned, humiliated... this whole night was unusual;
almost surreal. He was beginning to feel more and more like it was just a dream
and he would wake up in bed, cold, alone, unwanted. He felt tears prick at the
corners of his eyes.
This was the worst thing he could have imagined, except for seeing Papyrus’
dust in the snow. But being without Papyrus after having finally felt his
touch...it might kill him.
“WAIT, NO, I DIDN’T MEAN IT WAS A BAD THING…” Papyrus sounded startled as he
stopped touching Sans and pulled him into a hug.
Sans stared at his brother with a small squeak of surprise when he was pulled
into the hug and he shamelessly crawled into his brother’s lap squirming
teasingly against his brother’s girth..
“no…paps, it’s….not what you said that upset me. i just keep thinking that i’m
gonna wake up because there is no way i’m lucky enough for this to be real…” he
explained as he began to nuzzle his brother, still rocking his hips needfully.
“Sans….” Papyrus started softly as he hugged him even tighter. His magic
vanished for the moment. “THIS ISN’T-” He sighed and pulled him into a
passionate kiss. “HOW ABOUT YOU SLEEP WITH ME TONIGHT. THAT WAY THROUGHOUT THE
ENTIRE NIGHT I CAN REASSURE YOU THAT THIS IS REAL.”
Sans eagerly return the kiss while throwing his arms about his brother’s
shoulders. When he heard his offer he looked up with hearts in his eyes.
“yes papy, show me” he breathed. “make me yours”.
A small blush covered Papyrus’ face and his eye lights grew dimmer and he
licked his teeth angrily, it was obvious that the submissive talk was starting
to turn him on again. Sans grinned at his brother, noticing the blush. So
Papyrus liked submission? He could work with that. Papyrus’ magic started to
form again into his exposed erection, hard and throbbing, already leaking
precum. Sans was a bit surprised, but also smug that he could so easily make
his brother so aroused so easily.
Papyrus made a low growl as he grabbed Sans and laid him on the couch. “I’LL
MAKE YOU MINE THEN.” Papyrus promised with a deep purr before he kissed him,
hard and hungry, holding the kiss as he slowly slid inside of Sans.
“ahhnnn! papy! so bi~g…” Sans moaned while he threw his head back; clinging to
his brother and wrapping his legs around Papyrus’ hips as his walls fluttered
and stretched to fit his brother’s cock.
“so big!” He repeated with a happy whine.
Papyrus was blushing, holding to his brother’s sides as he thrusted into him
over and over, making each thrust harder and faster than before. He watched
Sans, panting, as Sans moaned underneath of him.
Sans loved how rough Papyrus was being and tilted his hips to let Papyrus ram
him deeper, his slick walls making lewd noises as he was being pounded. His
heart shaped eye lights were rolled back in his head and his tongue lolled out
as he panted, absolutely loving the brotherly attention he was receiving.
“uhnnnn! pap, papy!” he gasped. “harder! use me, brother! make me yours!”
“IF YOU INSIST~” Papyrus purred, he took one hand from Sans hip and slammed it
against Sans’ neck bone, choking him, and his other hand clawed at his rib
cage, using that as a handle to move him back and forth. Pap leaned down and
shoved his tongue in his mouth.
Sans gave a loud keening cry as Papyrus became abruptly rougher with him before
his breath was cut off when his brother wrapped his fingers around his neck,
slowly choking him. As his vision became fuzzy around the edges he felt as
though his mind was beginning to float, and all of his attention became
narrowed onto his brother’s hand around his throat, and his cock in his pussy.
He was beginning to drool.
Papyrus chuckled a little. “Honestly you’re so adorable when you’re
vulnerable..” He chuckled again. He was getting close. He moaned out and bit
what would have been his lip.
Sans gazed up at his baby brother with absolute adoration in his heart shaped
eyelights, basking in his brother’s praise. He would not have thought it, but
his brother’s praise was fueling his lust, making him burn hotter. He wanted
more praise. He wanted more. He thrust his hips against his brother, trying to
meet and match his pace.
“S-SANS I… I’M GOING TO CUM!…” He clawed harder onto his ribs trying to hold it
a bit longer but he couldn’t. He needed to make his brother his. He pulled out
and came all over his brother's chest and face. Papyrus smirked a little, it
was such a beautiful sight.
Sans gasped out a cry of complaint as his brother abruptly pulled out, although
he purred with pleasure as his baby bro came all over him. He pulled one hand
away from Papyrus’ shoulder and ran a finger through some of the cum on his
ribs and put his finger in his mouth to suck some of his brother’s taste.
“hmmm, you taste good, papy….” He moaned, rocking his hips a little
desperately. He looked shyly up at his brother. “i still have not come…”
Papyrus’ magic vanished. “Oh well we can’t have that now can we?” He leaned
down and kissed Sans’ opening before lapping it up with his tongue. He slid two
fingers in and thrusted them in and out as fast as he possibly could.
Sans squealed, and embarrassed by the sound clasped his hands over his mouth,
flushing bright red. “pa-papy!” he gasped. His brother’s ministrations quickly
brought him to his own end and he bucked his hips frantically against his
brother’s face and came apart with a wail.
Papyrus licked the area and his fingers clean after Sans orgasmed. “WELL THIS
WAS DEFINITELY A PERFECT END TO A LESS THAN PERFECT DAY....” He pressed his
teeth to Sans’ gently. “Let’s go to bed shall we? I promise I’ll keep you safe…
You’ll wake up to me tomorrow morning.” He whispered in a manner that was
almost sweet, and was certainly romantic, and Sans felt his soul throb with
love.
Sans allowed his magic to dissipate slowly and he smiled sweetly and satiated
at his brother and nuzzled him. “that sounds wonderful, papy…”
Papyrus picked him up and carried him to his bad. “PLEASE...I KNOW THIS...MAY
SEEM CRUEL, BUT CAN WE NOT LET ANYONE ELSE FIND OUT ABOUT THIS? MEANING I’M
STILL GOING TO BE AN ASSHOLE TO YOU IN PUBLIC...” Papyrus asked hesitatingly,
he seemed a bit worried but when Sans laughed he chuckled before kissing him
again. He laid down next to his brother. “I don’t think I’ve ever been this
happy…”
Sans giggled weakly and nuzzled his brother’s throat with a possessive purr.
“that’s ok, brother. i don’t mind. it’s our secret. To an extent i like it when
you are...aggressive. i like it when you praise me...but when you insult
me...it makes me a little wet..” He admitted shyly, his face flushing with the
thoughts of how dirty he was. Papyrus wrapped his arms tighter around Sans and
made a low possessive growl.
“YOU’RE A SLUT, BROTHER…” Papyrus accused with a pleased growl.
Sans chuckled as he cuddled happily with his brother, still not quite believing
his luck. He was here, with his brother, in post coital bliss. He had never
imagined that Papyrus would talk dirty to him, it was super hot. He grinned up
at his brother, “I guess i am, but i know i’ve never been this happy…” he
chuckled a little sadly as he hugged his brother tighter.
Something occurred to him and he glanced up at Papyrus shyly, flushing
brightly. “um, next time…can you….come inside me?” he asked softly before
dropping his eyes.
Papyrus blushed, not expecting that question at all. “You want me to come
inside of you?” He looked at him but smiled warmly. “Of course, my precious
Sans.” He pressed a kiss again this forehead. He had his arm wrapped around his
brother. “DO YOU THINK YOU’RE GOING TO SLEEP OKAY TONIGHT?”
Sans nuzzled his brother with a sigh of happiness and curled into his brother’s
arms sleepily. “of course i want you to…that…i want you to claim every part of
me…” he admitted with a soft smile before yawning. “and i think so, i might not
even have a nightmare tonight…it’ll be good to sleep the whole night for
once...” he murmured as he began to drift off.
Papyrus smiled and fell asleep shortly after his brother did. This is the
happiest he’s ever been in his life. His childhood was miserable but Sans
always made it better. “Thank you Sans…” He whispered as he drifted into
slumber.
***** Nightmares and flames *****
Sans had slept wonderfully, no nightmares, no invasive memories, no insomnia,
it was the best sleep he’d had in years, and he was so comfortable that he
never wanted to wake up. But he had work, and something else niggled in the
back of his mind as he blinked sleepily, slowly coming awake, in an unusually
peaceful manner. He had not had any nightmares, in fact, he had had a very,
very nice dream…
Papyrus called out for Sans in his sleep, tears rolling down his face.
Sans blinked fully awake, sitting up, he had heard his name? he looked around,
wait, he was in Papyrus’ room? He slowly realized that it had not been a dream,
he had spent a wonderful, beautiful night with his dear brother….he looked down
to see his baby brother weeping in his sleep, obviously having a nightmare.
“papyrus, papy!” he cooed as he leaned down to wrap his arms around his
brother, nuzzling his neck and pressing a skeleton kiss against the side of
Papyrus’ cheek, conjuring a tongue and lapping up his brother’s tears. “papy,
i’m here!”
Papyrus jolted awake, his eye light was red in defense. “STAY AWAY FROM US!” He
shrieked.
Sans flinched back ever so slightly, even though he knew Papyrus was not
talking to him, he was disoriented from the night terror. “S-sorry… I…” He
rubbed the scar on his face. “I’m sorry… H-HOW DID YOU SLEEP?” He quickly
changed the subject as more tears rolled from his eyes.
Sans shifted back smoothly to dodge his brother’s flails and then moved forward
once he calmed down again, nuzzling his neck and licking his tears while
purring softly.
“I slept wonderfully.”
He looked at his hand and the shadow of a circle was forming but he quickly
shook it away. “T-that’s great. YOU DESERVE IT..”
Sans saw that his brother was still unsettled from his nightmare and was not
being soothed so he sat back to peer up into his brother’s face.
“how did you sleep, papyrus? you look a little, rattled.” he teased lightly.
“FINE. I SLEPT FINE.” He pressed his hands to his temples. His other hand had
Gaster’s circle looming over it, he forgot to shake that one away too. “I
SHOULD GET READY FOR WORK…”
“don’t lie to me papyrus.”  Sans growled low in his throat and glared at his
brother. “you are still shaking. i won’t let you go in such a state…” he
trailed off when he saw the circle looming on one of Papyrus’ hands and his
eyes widened. “what….is wrong with your hand?”
Papyrus quickly shook it away. “NOTHING. IT IS JUST A THING THAT HAPPENS WHEN I
HAVE A NIGHTMARE, NOTHING THAT THE GREAT PAPYRUS CANNOT HANDLE. DON’T WORRY
ABOUT IT.” He stood up. “UNDYNE WILL KILL ME IF I’M LATE…”
Sans narrowed his eye sockets and stood up and stood in front of his brother
with a huff of annoyance, his arms akimbo, totally comfortable with his present
nakedness. His brother was not usually so evasive, in fact he was usually
incredibly straightforward and blunt. Tact and Papyrus were fleeting
acquaintances at most. But Papyrus obviously did not want to talk about
whatever it was that had him crying in his sleep. Sans would let it go for now,
but he wanted to soothe his brother before letting him leave for patrol, and he
had a brilliant idea of how to go about doing that. He licked his teeth
hungrily and gave his brother a half-lidded leer.
“fine. we’ll continue this later, but first i’m going to calm you down.” he
smirked as he knelt down in front of Papyrus and began to lick and suck at his
pelvis, determined to bring his brother pleasure. He also wanted to taste Papy
again. His brother felt so good in his mouth, heavy and hot.
Papyrus squeaked in the most adorable fashion, his face glowing a bright red,
“S-SANS! WHAT ARE YO- I’M GOING TO BE-hhhnnnnngggggg~” his magic started to
form a penis right before Sans’ face. “S-SANS~ j-just make it quick..” He
blushed as his brother sucked on him. It felt so good but he really had to get
ready for work.
Sans smirked up at his brother in triumph and then opened his mouth wide,
letting his tongue loll out, and swallowing his brother’s cock as far back as
he could, choking for a moment before his conjured throat adjusted and his eyes
rolled back and he hummed in pleasure as he sucked his brother happily,
enjoying the taste of his magic.
Papyrus was cumming quickly. “A-ah! S-SANS!!” He screamed as he came all inside
of his brother’s mouth. Sans swallowed eagerly, humming with pleasure as he
felt his brother’s magic meld with his own. Papyrus’ genitals disappeared
shortly after that. He was panting, his face flushed, but he seemed much more
relaxed and Sans felt triumphant. “I.. Have to go to work now..I’LL SEE YOU
TONIGHT.” Papyrus seemed a little flustered and Sans resisted the urge to tease
his little brother.
Sans licked his teeth to make sure he had not missed any of his brother’s cum
and with a chuckle as he decided to let Papyrus get away with avoiding the
subject. For now. He smiled sweetly at his brother and got up to stretch.
“ok, papyrus. have a good day, kick ass. i’ll get going on my shift at the
sentry station too.” Sans said with a wave. He watched his brother get dressed
and leave, and to his pleasure Papyrus stopped to drop a kiss to his forehead
before he left. Sans felt as if he was floating, he was so happy.
If he had known that Papyrus actually reciprocated his feelings, and that he
would be so sweet about it, and that it would make him so happy, he would have
kissed his brother much sooner. The thought of just reaching up and pulling
Papyrus into a kiss while he was in the middle of screaming at Sans for his
failure to do whatever had him flushing with a small guilty grin.
He was so happy that he actually felt a surge of energy, he took a shower for
the first time in weeks, scrubbing his bones until they glowed. He got dressed
in a clean set of clothing although it was identical to what he had been
wearing, just less dingy.
He was still happy as he went downstairs and ate some leftover breakfast
spaghetti.
He took that happiness with him as he took a Shortcut to his sentry station,
and he actually managed to stay awake for most of his shift, only having to
take a couple cat-monster-naps the whole time. All told he was actually proud
of himself.
His shift was uneventful and boring, as always. No humans. He sometimes
wondered if there were any humans left; maybe they had all killed themselves.
Of course that meant the monsters would never break the barrier, but in his
darker moments he sometimes thought that it did not matter.
But now that he and Papyrus were, well, something, he was starting to
hesitatingly think of having a future with him. Of them. Together. And being
together on the surface, not having to worry about always being on the
defensive, not having to play any parts in public...it would be glorious. It
made his soul hum and warm under his ribs, and he could see the glow through
his shirt. He felt embarrassed by the blatant display of love.
And speaking of their new relationship...he frowned thoughtfully to himself as
he stuffed his hands in his pocket and took a Shortcut to Snowdin, on his way
to Grillby’s for some well deserved after work Mustard. He should probably
break things off with Grillby. Not like he and Grillby were anything official,
but since he payed for his tab with his body that would still probably count as
cheating on his brother.
He flushed as he remembered his brother’s possessive growls from last night.
His brother had said that he wanted no one else to touch Sans; and although it
had been spoken while in the throes of passion Sans was inclined to believe
that Papyrus meant it. His brother never said anything he did not mean, he was
so cool like that. It was a point of honor for him. And his possessiveness was
really a turn on, and Sans was inclined to be obedient.
So that meant telling Grillby they needed to stop. With that in mind he
bypassed the bar and stopped by the house first to grab some gold from their
stockpile which they had hidden in a safe box. He took enough to cover his tab
(with a bit of extra) and then with a spring in his step and a wide toothy grin
he went to the bar.
As Sans sauntered in he saw the usual crowd at their usual seats with their
usual poisons to drown their sorrows (not that all of them were upset, just
about half), and he gave a jaunty wave. A few seemed confused by his excess
energy but the rest just called out to him before returning to their
conversations and their drinks. He wound his way through the crowd until he got
to the bar and grabbed one of the stools, waving at Grillby to let the purple
imp know he was there. Grillby acknowledge him with a leer and after a few
minutes he plonked a glass of mustard mixed with alcohol before him; his usual
poison of choice.
Sans sipped his drink slowly, savoring it, enjoying the spicy burn, watching
Grillby work and listening to the other patrons. Grillby was a little short
tempered, and quite aggressive, but he was a good bartender and kept up with
all his customers in a way that Sans always found impressive. And if he was
being honest, Grillby was pretty darn hot (hyuk), but, in his own opinion his
brother was hotter, and Sans also had an emotional attachment to him, so it was
really no contest. He would chose his brother every time.
“You certainly seem in a fine fettle today, Sans…” Grillby commented while
placing a second glass before Sans. Sans usually drank himself nearly
incoherent of a regular basis, so this was the usual way of things. But today
he was determined to only drink in moderation so he could be home to greet his
brother. The thought had him grinning and he turned to grin up at Grillby,
trying not to look too excited although he figured he was probably flushing a
bit.
“uh, yeah, grillbz, i actually, ah….met….someone...ya know?” He started to
explain, feeling a darker blush rise to his cheeks and he ducked his head shyly
as he started on his second glass.
“Oh…?” Grillby prompted in a dark tone that Sans was too distracted to notice.
“yeah….so…” Sans glanced up and saw that Grillby had him fixed with a fiercely
intent stare which usually had Sans squirming in his seat. He dropped his eyes
hurriedly. “so...um, our...arrangement. i...uh, think i should just start
paying for my tab the, uh, usual way, with gold.”
Grillby was silent for so long that Sans chanced another look up at the
bartender, he felt a chill run down his spine at the look Grillby was giving
him. Imps did not usually have the most expressive of faces, but Sans had no
trouble reading the look on Grillby’s right now. He looked absolutely pissed.
Sans shivered and dropped his eyes again, playing with his glass for a moment
before chugging it back and reaching into his pocket to slap his gold on the
table.
“so, um, i gotta go early tonight so...this should cover my tab, see ya…” he
muttered quickly as he slid off his stool, nervous sweat on his skull. Before
he could leave though Grillby had his wrist captured in a crushing grip that
had him biting back a whimper.
“Why don’t we discuss this in the back…” Grillby growled as he dragged Sans
into the storeroom while the other patrons kept drinking.
---
“SANS, ARE YOU HOME?” Papyrus called as he entered the house that night,
closing the door gently before walking up the stairs to his room to change out
of his Battle body.
Sans had been in his room, huddled on his bed while wrapped in a blanket and
staring blankly at the wall when he heard his brother come home. When he heard
Papyrus he hesitatingly crept out of his room and stood indecisively in his
brother’s doorway, wringing his hands, trying to decide if he should tell
Papyrus what had happened. He did not want to bother him, or add to his
stress…he was wearing his jacket with the hood up shadowing his face and his
hands crammed in his pockets.
He tried to stop shivering, and winced as every movement sent sharp jolts of
pain from his pelvis up his spine.
“OH, THERE YOU ARE SANS.” Papyrus turned to greet him, a cautious smile on his
face, but it became a frown when he saw Sans. “WHY DO YOU LOOK LIKE THAT? DID
SOMETHING HAPPEN? DO I NEED TO KILL SOMEONE?”He approached his brother.
Sans eyes shrank to pinpricks and he dropped his gaze to the floor as he
hunched his shoulders. Papyrus was so perceptive, and...Sans had never thought
he would behave so protectively. He’d like it if Papyrus killed Grillby, but…it
might set a bad precedence and it might actually give Papyrus trouble. He
couldn’t burden his brother like this. He forced a smile on his face although
it did not reach his eyes and he looked up at his brother, trying to blow it
off.
“nah, it’s cool, bro…”
Papyrus’ old attitude quickly returned. He slammed his hand against the wall
right next to Sans’ face. “WHAT THE FUCK HAPPENED SANS?! DON’T MAKE ME BEAT IT
OUT OF YOU! WHO THE FUCK HURT YOU?!”
Sans flinched and looked up at his brother, but not fearfully, more like he was
ashamed.
“papy…i…i’m sorry. i didn’t….” he was trying not to cry and he dropped his
eyes, not wanting to see the disgust in his brother’s eyes. He shifted his
weight from foot to foot, wringing his fingers together so roughly that the
scrape of bone on bone was clearly audible.
“grillby collected his tab today…” he muttered.
Papyrus raised a brow bone and just gave Sans a look of exasperation. “I KNEW
YOU OWED HIM MONEY, YOU SPEND ENOUGH TIME THERE EVERY NIGHT DRINKING YOURSELF
UNCONSCIOUS...WHY IS THIS SUCH A BIG DEAL…? HOW MUCH DID YOU OWE HIM EXACTLY?”
He crossed his arms and scowled at his older brother waiting for some sort of
terrible response.
Sans closed his eyes in annoyance and gave a trembling sigh before raising his
head to hesitatingly meet Papyrus’ eyes. His brother really was naive in some
ways. It would have been somewhat cute in any other situation.
“he….won’t accept gold from me paps…” he prompted, trying to get his point
across without actually saying it.
Papyrus’ eyes widened and he forcefully grabbed Sans’ shirt collar. “WHAT THE
HELL DO YOU MEAN SANS? WHAT THE FUCK DO YOU MEAN HE WON’T ACCEPT GOLD?!” He
gritted his teeth to the point it was audible. He was getting the point now but
he just wanted to be sure before he snapped.
Sans shrank in on himself and ducked his head, not meeting Papyrus’ eyes and he
felt himself flushing in shame and anger and self-hatred. He was so weak, so
worthless. Papyrus would abandon him…
“he…takes….the….tab out of….my body.” he whispered, closing his eyes in shame.
“i….tried to pay him today…with gold, and….tried to break it off with him,
because…i have you…i did not tell him about you but i tried to break it off
and…and…he…he….wouldn’t…accept it as payment…and forced me into the storeroom,
and….he….” He sobbed and could not continue. “i’m sorry, i’m sorry
imsorryimsorry…” he whimpered.
Papyrus lifted his up by his collar and slammed him against the wall as hard as
he could then letting him fall to the floor. He had no words to even say to his
brother. Anger boiled deep inside of him ready to escape, he took it all out on
his brother, punching and kicking him until he was in tears. “I SEE HOW IT
FUCKING IS, YOU SLUT! YOU’LL SLEEP WITH ANYONE!I” He kicked him across the
floor out of his room and locked the door.
“BECAUSE I’M SUCH A GOOD BROTHER, YOU HAVE FIVE MINUTES TO TELL YOU BOYFRIEND
TO GO HIDE UNLESS HE WANTS TO BE DUST TONIGHT!”
Sans had not expected his brother to be happy to hear about his affair, or his
rape, but he had not expected his brother to…throw him out like this and act
like he’d wanted it. But he should have known it was too good to be true. With
tears in his eyes he curled up outside his brother’s door, trying not to sob
and he winced, at the injuries his brother had inflicted on him which paled in
comparison to the pain in his pelvis from his earlier rape or the pain in his
soul from his brother turning from him.
He sat there in shock for an indeterminate period of time, sobbing.
But he was also beginning to get angry, he had tried to be good, he and Papyrus
had only gotten together last night, and he only ‘paid tab’ to Grillby once a
week or so, and it was not like, a regular thing, and he had gone to break it
off right away, it was not his fault that Grillby could not take no for an
answer…and he had been honest with Papy too, so why take it out on him?! He
struggled to his feet.
“i don’t care what you do to that rapist. but maybe you can compare notes on
abuse!” he screamed through the door before turning and limping painfully into
his room and slamming the door before crumpling into a sobbing mess.
---
The sound of Sans screaming and the door slamming made him jump. Compare abuse…
But Papyrus would never…he remembered throwing Sans to the floor, attacking him
like an animal, just because he had been raped, for trying to be faithful to
Papyrus. His soul clenched and he felt horrified.  Fuck… Fuck fuck fuck he did
it again.
He had not meant to, but the thought of someone touching Sans, hurting Sans, it
had made his vision swim with red, and he had not known what he was doing. He
could never control his temper.. He tried so hard around Sans especially
through everything that happened but he failed. He took his anger out on his
brother, hurt him for his own pleasure, just like his father… No. Tears welled
up in his eyes. He was only going to turn bad like him.
He pulled a switchblade from his pocket and drove it deep into his arms. There
were scars before from other times he went overboard on Sans. There were scars
from two days ago when he kicked his face in. This was all proof he would never
get better. He couldn’t. He dropped his knife and grabbed his leather jacket
and scarf then ran out of this house with no intention of coming home. He
couldn’t hurt Sans anymore if he was not around…
***** Reconciliation *****
Sans had wrapped himself back up in a blanket as he sobbed on his cold bed when
he heard his brother leaving his room, and leaving the house…the door slamming
behind him with an eerie finality. Was he going after Grillby? Why would he
leave without saying anything? Sans had expected Papyrus to confront him again,
for yelling if nothing else.
He scrubbed his arms over his eyes and pushed himself up. He had a bad feeling
in his soul. He took a shortcut to just outside the house and looked around
desperately for his brother, just barely resisting the urge to call out his
brother’s name. He did not want to draw attention to himself or ruin his
brother’s reputation.
His brother’s reputation was the most important thing to him right now, it was
what kept them both safe, and his brother’s position was what kept them housed,
clothed, fed. And his brother had worked so hard for everything they had, Sans
refused to ruin it for Papyrus. He had to stop Papyrus from ruining everything
he had worked so hard for, Sans was not worth it.
---

 Papyrus was running as fast as he could, avoiding the main streets as he
passed through the alleyways so he would not have to face anyone. He made it
deep into the Snowdin woods before he just collapsed. Fear was starting to
corrupt him. He was suppose to be strong. Bad things happened to him when he
wasn’t. Why did he always beat up Sans? What made him any different than his
demon of a father? The circles on his hands were visible again and so were the
obscure cracks on his face.
He fell in the snow and just screamed. He didn’t care if he drew attention. He
was having a panic attack, he didn’t care about anything right now.

 ---
Sans stood indecisively in the doorway, looking back and forth, looking for any
sign of his brother. He could tell that he had not gone to Grillby’s, so where
was he? Then he thought of a place in the forest where Papyrus liked to go when
he was upset as a baby-bones. He snapped his fingers and took a Shortcut.
He did not see Papyrus, but he could feel him nearby, Papyrus’ soul called to
him, he was terribly upset. Sans was taken aback, why was Papyrus so upset?
He ran towards his brother, one arm around his ribs.
“papyrus!” He called as he finally lay eye lights on his younger brother. “what
are you doing out here?” He started to walk towards his brother, feeling relief
that Papyrus was okay, he’d been so worried....he finally had a good look at
his brother and he slowed as he grew concerned.
Papyrus was hyperventilating, his eye lights the smallest of pinpricks as he
was very obviously in the middle of a panic attack, his body trembling so much
that Sans could hear his bones rattle from where he stood. He had the same
cracks as Gaster and the same hand holes as Gaster. He looked at Sans only
panicking more, he started to hyperventilate. The circles in his hands formed
to actual holes. He needed help. He was terrified and angry and pathetic and
jealous. Sans could feel the emotions resonating with his soul.
Sans froze in shock for a moment as he saw the spectre of Gaster overlay his
beloved brother, sucking in a slow breath through his teeth as his mind spun in
fascination.
Sans clutched with one hand at his ribs, right over his frantic soul as he saw
his father peering through his brother’s eyes. He took a deep shuddering
breath, his eyes glazing over and he bit back a moan. He’d missed his
father...it had been so long since he had last seen Gaster. He felt his bones
warm as he thought of his father, he knew Gaster was not a good father, not a
good master, but he had never minded much, unless it caused Papyrus pain…
That was what snapped him out of his fascination. Papyrus was in pain. How long
had Papyrus been suffering with this haunting, how long had he been suffering
in silence? He forced himself to take a step forward, and that step broke his
paralysis and he ran across the small clearing and almost threw himself into
his brother’s arms as he began to nuzzle his throat.
“papy, papy, it’s ok!”
It was working, his brother was successfully calming him down. It took a few
moments but the Gaster marks were slowly fading away until he was his normal
self again.
Once Papyrus completely recovered he stood up like nothing ever happened.
“LET’S GO HOME. ARE YOU INJURED? SHOULD I TAKE CARE OF YOU TONIGHT?” He was
hoping he could make this about his brother again. Sans did need the attention
and care.
Sans felt a great relief and felt a weight lift of his soul when his brother
became calm again. He stood up slowly, not bothering to hide his slight wince.
‘i’ve had worse, bro…” he said with a shrug when Papyrus asked about his
injuries. He scratched the back of his head thoughtfully and darted his eyes to
the side wondering if he should mention Grillby again and his shoulders hunched
and he decided he did not want another fight.
 “and…i’d like to sleep with you again tonight but…as for…taking  care  of me…”
he felt terribly unclean, he never wanted anyone to touch him again. But all
the same, he needed his brother’s touch. He would not let Grillby soil what he
and Papyrus had. He turned determined eyes to Papyrus. “i want you to claim me
as yours. again and again until no one else will dare touch what’s yours.”
“Sleep with me again…?” Papyrus muttered slowly, sounding not quite pleased by
the idea and Sans remembered the night terrors and how he had to witness that.
“MAYBE THAT IS NOT SUCH A GOOD IDEA…” He shook his head and gave Sans a weak
smile, pulling him into a gentle hug. “IT MAKES ME HAPPY THAT YOU STILL WANT
ME...I’M SORRY JEALOUSY OVERTOOK ME…” And he leaned down to kiss Sans gently,
lovingly. Sans melted into his brother.
After Papyrus pulled away Sans leaned up to press a gentle skeleton-kiss
against his cheek, nuzzling his neck vertebrae and then leaning against his
chest.
“i don’t mind you being jealous, papy…” he murmured softly and he wrapped his
arms around his brother. “and i don’t mind you…hurting me a little…i…just want
you to talk to me when you’re upset.”
“I JUST, CAN’T GET ANGRY SANS, CAN’T GET UPSET. I CAN’T CONTROL MYSELF WHEN I’M
ANGRY...I CAN’T EXPLAIN- I CAN’T TALK TO YOU ABOUT IT...I’M NOT ALLOWED TO BE
WEAK, CAN’T LET YOU SEE ME WITH ANY WEAKNESS...I’VE TOLD YOU THAT BEFORE,
SANS!” Papyrus exclaimed, sounding a combination of angry and terrified.
Papyrus’ words confirmed Sans’ fears that Gaster had irredeemably traumatized
his baby brother and he felt pure hatred flare in his soul briefly before
allowing it to ebb and he smiled up at his brother with understanding.
“that’s fine bro. you are the strongest monster i know. i won’t ask anymore,
just…let me be with you? i…love you too much to…want you to be alone. and…” he
blushed. “i like waking up in your arms…”
Papyrus blushed slightly at Sans’ words and it seemed to break the tension, he
took a deep breath, suddenly relaxing into a calmer attitude and he hugged Sans
tighter.
Sans looked down and gathered his pride in a little ball and figuratively threw
it over his shoulder.
“also…can…you….do something…about grillby?” he almost whispered, trembling
against his brother.
“OF COURSE...DO YOU REALLY THINK I WAS JUST GOING TO LET HIM GET AWAY WITH
THIS? I’LL MAKE HIM PAY FOR TOUCHING YOU.” Papyrus snarled as he tightened his
arms around Sans possessively.
Sans nuzzled his face against his brother’s chest, feeling relief. “i did not
think you would, i just wanted to hear you say it…”
“DON’T WORRY SANS...HE WILL BE PUNISHED. AND AS FOR SLEEPING WITH ME, WELL... I
GUESS ANOTHER NIGHT WON’T HURT...” If he could get through this night without
night terrors everything would be alright. “HOW ABOUT WE GO TO BED AND THEN IN
THE MORNING I’LL DEAL WITH GRILLBY?” He kissed his brother's cheek. “IT’S
DANGEROUS TO BE HERE THIS LATE. LET’S GO.”
Sans hummed happily and grinned up at his brother. He liked getting his way,
and being submissive and shy seemed to get his brother to do things his way, he
would have to remember this.
“do you want to shortcut with me?” he offered with a shy smile, he had never
showed this power to his brother, and was not quite sure how his brother would
react.
“ALRIGHT, JUST HURRY UP AND GET US OUT HERE…” Papyrus sounded impatient, and
gestured flamboyantly for Sans to lead the way, apparently taking Sans’ words
as the literal definition. Sans chuckled and took his brother’s hand. He gave
his brother a wink and bent space around them, bringing them out in the middle
of the living room.
“now, we’re home!” Sans cheered, spreading his arms as he dropped Papyrus’
hand, spinning to face him as he gestured grandly.
Papyrus blinked slowly and looked around, acknowledging that there were indeed
in their living room.He looked down at Sans, his expression almost impressed
and Sans grinned broadly.
“awesome, huh bro?”
“I’M GOING TO BED. ARE YOU STILL JOINING ME?”’ Papyrus grumbled as he looked
over at him, a sad expression on his face.
Sans grinned broadly and chuckled. “yes, of course. every night, given the
chance!” he said enthusiastically as he chased after his brother, moving faster
than he had in years.
Papyrus grinned as he led the way to his room. He slowly stripped then put on a
pair of sweatpants. “HONESTLY I’M EXHAUSTED.” He collapsed on his bed. Too much
had happened today. He felt his brother snuggle up against him. He couldn’t
help but smile and wrap his arms around him. “Good night Sans.”
Sans curled into his brother’s chest and felt his body relaxing, feeling safe
for the first time since this morning. “goodnight, brother…” and he drifted off
to sleep.
---
Papyrus had the same nightmares as he had the last night. It was a twisted
melding of memories and fears, and all he felt was pain and the fear of
weakness. He woke up in the middle of the night and left, not wanting to wake
up Sans with his screaming and thrashing. Papyrus was outside sitting in the
snow with a flask in his hands. The Gaster marks came back. This was so much
easier to hide when Sans wasn’t so close to him… He needed new ways to hide
secrets.
Papyrus finished the flask and passed out in the snow. The Gaster markings got
worse. At least when he was alone in his room he could hide this. The night
mares continues and he rode them out until morning. Papyrus didn’t wake up,
with the lack of sleep he was getting he just stayed there tiredly freezing in
the snow.
---
Sans slept well, Papyrus’ presence keeping his nightmares at bay, his
subconscious aware of his brother’s soul on a deep level and comforted out of
any anxiety. But once Papyrus left he fell adrift, and immediately began to
thrash and moan fretfully, reaching for his brother as in his mind he raced
through a dark tunnel, trying to rescue Papyrus from the human, but knowing he
would be too late, and only find dust. he began to cry as he fell into
darkness, alone and bereft.
“papyrus!” Sans sat up in bed, gasping and crying. As he realized that he had
been having a nightmare again and he wrapped his arms around himself and
whimpered turning to Papyrus for comfort….only to find Papyrus not in the bed.
He leapt out of the bed almost before he realized what he was doing.
“papy?” he called, worried. Maybe he had to use the bathroom? They did not
often have to relieve themselves of spent magic unless they had a build up, but
it was possible…or maybe he got thirsty?
After checking his room (just in case), the bathroom, and the kitchen and
living room he concluded that his brother was not here. He pulled on his shoes
and coat and opened the door, thinking maybe Papyrus had gone to Grillby’s…and
almost tripped over the half-frozen prone form of his brother.
“pa-papy?” he gasped, horrified. With a whimper he knelt down and pulled
Papyrus into his arms and shortcutting them into Papyrus’ room. He stripped
Papyrus down to his bare bones, and followed suit, and bundled them into the
bed, trying to warm his brother up.
The flask tumbled down to the floor as Sans stripped his younger brother. The
Gaster markings were also very visible, his hands and actual holes in them.
Papyrus whimpered in pain slightly unconscious. “S-Sans….” He mumbled in
between groans of pain. His body was starting to warm up a bit more but he
wasn’t awake completely.
Sans nuzzled his brother’s neck and planted skeleton kisses all over his face,
allowing his soul to glow with love and lust, hoping it would warm his brother.
“papy, brother, love, i’m here.” he breathed softly and rolled to lay atop his
brother, desperate to warm him.
Papyrus slowly opened his eyes and examined his brother. “Sans…?” He sounded
like he was in horrible horrible pain. He coughed up a bit of dust. “Sans….”
His arms wrapped around the other weakly.
Sans lifted his head when he heard his brother’s voice, tears in his eyes.
“papyrus!” he leaned up to press his teeth against Papyrus’ gently. “please
stay…stop leaving…” he thought hard for a moment, remembering what Papyrus had
said earlier. “if you cannot be seen as weak….just blindfold me. and we can use
earplugs too….that way, no witnesses, right?”
“M-Maybe…” He examined the holes in his hand. “IT…HURTS….” He grunted “I JUST
WANT IT TO STOP....” He gripped onto Sans shirt. Sans could see the pain in his
eye sockets. “I DON’T WANT TO LEAVE...” The pain was getting worse.
Sans leaned up and pressed a skeleton kiss to his brother’s mouth before
pulling back slightly and licking his brother’s teeth lightly and he moved to
straddle his brother’s lap. He began to lick down his brother’s neck, pausing
to bite lightly now and again and grinding his hips softly against his
brother’s.
Papyrus rolled over making Sans  fall off. “NOT NOW SANS….” He clawed at his
face. “I THINK I’M GOING TO GO TO GRILLBY’S. KILLING SOMEONE SHOULD MAKE ME
FEEL BETTER…”
Sans sat there thoughtfully for a moment, eyes darting to his brother’s face
and then away and he flushed.
“can…i watch?” He asked softly, squirming as the thought of watching his
brother completely overpower Grillby was making him so wet.
Papyrus sat up glancing over to Sans with a considering expression before
smirking, “ALRIGHT, IF YOU WISH.” He got up and started to get dressed. “I
THINK I’LL BRING SOMETHING….SPECIAL….FOR THE OCCASION.” Papyrus rustled through
his closet, he pulled out a leather whip and cracked it on the floor. “I
HAVEN’T USED THIS IN A WHILE...”
Sans could not keep the unholy glee from his face and he got up eagerly and
pulled his clothing back on quickly.
“i think i’ll enjoy this…watching you…” Sans admitted with a small blush. He
pulled on his coat and shoes, ready to go. “after you, boss.” The term of
respect was now a term of endearment. He was ready to follow his brother to
hell and back.
Papyrus gladly accepted and lead the way to Grillby’s. His mood went back to
normal, you couldn’t even tell he cared about anyone, even his brother. He was
ready to kill.
He kicked down the door to the bar, they probably haven’t even opened yet.
“GRILLBY!!” He cracked the whip on one of the wooden chairs, shattering it into
millions of wood shards.

Chapter Notes
     I know a lot of you were looking forward to this!
See the end of the chapter for more notes
Sans followed meekly behind and to the left of his brother, scowling and
hunching his shoulders as if he was angry and unhappy, as if he was being
punished. But his eye lights were glowing with unholy glee and he was enjoying
the show already. Papyrus was in his element, his spine straight, his eyes
blazing, his voice deep and dominating. Sans was so wet. He never would have
thought that his brother’s anger would turn him on so much- at least when it
was not directed at him.
But it did; as soon as Papyrus challenged Grillby and started being destructive
Sans felt lust coil in his pelvis, his face flushing and he fought to keep a
wide grin off of his face. He almost laughed as he imagined the expression on
Grillby’s face when Papyrus just dominated the scene. His brother was so cool.
But then he actually did see Grillby, and his mind stuttered to a halt. He
could not help but remember what had happened just a couple hours ago when he
had last been in here, his mind replaying the incident on a frenetic loop that
had him shaking and sweating within moments despite his mind frantically trying
to block out the images.
Grillby looked startled at first by the intrusion, his purple flames flickered
pinkish red momentarily as he turned from where he was cleaning behind the
counter, and his face gave the impression of annoyance and disgruntlement, but
it soon smoothed out to calm arrogance. The flickering of his flames flared up
and then lowered into a simmer.
“And what do I owe to this…honor? It is closing time, as you are surely aware?”
He asked as though completely bored and uninterested in the answer, although
with the way his flames flickered Sans could tell that he was annoyed with the
damage. His purple-red eyes flared with the reflection of his flames and Sans
had the impression that Grillby was examining the damage closely. Really, the
only thing Grillby actually cared about was his bar, so Papyrus damaging it was
just about perfect as far as Sans was concerned. Perfect as a starter at least.
He would not be completely satisfied until Grillby was dusted; he did not even
want the monster tortured, he just wanted him dead.
“YOU KNOW EXACTLY WHY I’M HERE.” Papyrus growled as he lashed his whip again,
destroying a second nearby chair. “YOU TOUCHED SOMETHING THAT BELONGS TO ME,
AND BY UNDERGROUND ETIQUETTE I’M ALLOWED TO PUNISH YOU IN ANYWAY THAT I’D
LIKE…” He started his way to the bar tender.
Grillby did not have a face as such, but he gave the impression of narrowed
eyes as his attention shifted from the imposing figure of Papyrus to the
smaller figure coming behind him, hunched inside his overly large hoodie. When
his gaze landed on Sans’ the smaller skeleton flinched slightly and shifted to
stand behind his brother, his eyes dropping to the floor in shame and to
Grillby’s amusement, fear. He turned his attention back to Papyrus, grinning
smugly and feigning ignorance.
“I have no idea to what you are referring to, but if you keep destroying my
property I’ll have to add it to your brother’s tab…” Grillby responded with a
low purr that had Sans shivering and trying to vanish behind his brother, tears
springing to his eye sockets. He could not help but remember what had happened
here earlier today, Grillby dragging him into the storeroom, none of the
patrons caring, even ignoring his screams….Grillby enjoying his screams.
Hurting him on purpose to make him scream...the patrons in the bar just
laughing and yelling encouragement through the half-closed door...
Sans wanted to cling to his brother, maybe this was  a bad idea, seeing
Grillby, seeing him and being seen by him, was starting to make him feel small
and weak and helpless and he wanted to leave now. He looked up at his brother,
hoping Papyrus would not see how weak and pathetic he was, almost trembling in
fear from the fire elemental. He was not really able to focus on what his
brother or the bartender were saying, but when Grillby all but purred the word
‘tab’, he could not help the strangled yelp of fear that he was not quite able
to stifle and he started to back away with his eye lights flickering out.
“heh….br-boss…i…think…i…will wait outside…” he stuttered softly, trying to
maintain an even tone. Grillby’s attention turned to him and the promise of
retribution that seemed to glow from him had Sans feeling sick as he glanced up
at his brother. Papyrus stepped fully in front of Sans protectively, so that
Grillby could no longer see his brother, which also cut off Sans’ veiw of
Grillby; freeing him of his paralysis. Sans relaxed slightly, and backing
carefully away he exited the bar as quickly as he could.

---

Papyrus cracked the whip once before lashing out with precision, slicing
through Grillby’s cheek. “I’M SORRY, WHAT WAS THAT?! MY BROTHER DOESN’T OWE YOU
SHIT . I ONLY KNOW THAT BECAUSE YOU REJECTED ALL HIS MONEY.” He nodded slightly
at Sans when he left before focusing all of his attention and killing rage on
the monster before him. He was even more angry than before now that he had seen
Sans tremble in fear from just being in the same room as his abuser.
“SO LET ME GET STRAIGHT TO THE POINT. I’M GOING TO KILL YOU. EITHER YOU CAN LET
ME KILL YOU OR YOU CAN HUMOR ME AND FIGHT BACK.” The whip cracked on the floor.
“WHAT WILL IT BE?” Papyrus snarled, only his honor allowed him to even give
Grillby this warning, this option. Otherwise the other monster would already be
dead. Well, he’d be dead no matter what.
Grillby scoffed, clearly disbelieving Papyrus had it in him to carry through
with his threat and he placed his hands on his hips as he gave Papyrus a
disdainful glower. He started to say something but he growled in annoyance when
the whip licked his cheek. He narrowed furious purple red eyes at the skeleton
before something seemed to suddenly occur to him and his eyes widened and he
began to start laughing coldly.
“Oh I see! You’re just jealous I had him first!” Grillby smirked knowingly,
pausing to lick his lips with a leer. “He’s never had cause to complain of
our…arrangement before, but he suddenly comes to me, begging me to change how
he paid his tab, he would not tell me why, but I had my suspicions…but he would
rather have YOU?! That is rich!” He started laughing again before straightening
up and giving Papyrus a slow once over of disdain. “I doubt you can do for him
the things I can…he makes the most delicious sounds when I take him…he’ll be
back before long. Why don’t you just leave now, I’ll let the damage stand.”
Then he turned dismissively.
Rage. That was all Papyrus could feel or think right now. His eyes glowed red
and he gritted his teeth. “DON’T YOU EVER FUCKING TALK ABOUT MY BROTHER LIKE
THAT!” The whip cracked shear across Grillby’s back, his intent to kill
transmitted through the weapon, tearing into the magic flame of the elementals
form and causing him to shriek. “I’M GOING TO KILL YOU THEN PRETEND YOU NEVER
EXISTED, YOU DISGUSTING SPECK OF GARBAGE!”
Grillby whirled with incredulous fury, purple flames flaring out, black at the
tips and his narrowed eyes flared a dark blood red and his teeth flared into a
snarl as he gave the impression of disbelieving rage.
“You little worm! You dare…what the fuck is your problem?!” He was almost
incoherent with rage and his flames colored a darker violet shade ran through
with black and white. His hands curled into fists aglow with darker flames. He
took a step closer, tendrils of flames starting to curl up from between his
fisted fingers as he formed flaming lashes. “Since when have you cared about
that slut of a brother of yours? He was  begging  me for it!”
“I’VE  ALWAYS  CARED ABOUT HIM! FOR EXAMPLE, I’VE WANTED HIM BUT NEVER TOOK
ADVANTAGE UNLIKE  SOMEONE  WE BOTH KNOW!” Red bones surrounded the two like a
cage. Now Grillby would be forced to stay here and fight, or die. “SO WHAT WILL
IT BE? ARE YOU GOING TO TRY AND KILL ME OR WHAT?”
Grillby gave the impression of narrowed eyes as he began to circle in towards
Papyrus. He made an angry hiss like a steaming water kettle and his flaming
lashes lengthened until the reached the floor. He flicked them experimentally
and then flung them out at Papyrus, aiming for the face.
“Or, I’ll do more than try. I’ll  char you to dust and then fuck your dear
brother in your remains.” He growled ferally. “And make him scream my name as
he cums all over your dust, forgetting all about you as he submits to me, just
like he has before.”
---

Sans had been standing on the stoop just outside the bar, shivering in the
cold, arms huddled around his ribs. His eye lights were dim and he stared at
the dingy snow at his feet, mind feeling as though it was swirling in sludge
and it was hard to think straight. But slowly he started to calm down, he
slowly stopped panicking and with a slow blink he looked up at the empty street
and realized with a guilty start that he was a filthy coward. He was always
like that, just, a weak little wuss. His brother was in there, perhaps
endangering himself, and all for Sans. He should be in there, watching. With a
small nod he turned and enter back in quietly, hoping to not distract his
brother. He saw a bone cage surrounding his brother and the bartender.
Papyrus dodged most of the flames. He felt as though Grillby was going easy on
him. He summoned a bone and shot it straight into Grillby’s chest. “IF YOU WERE
SO SPECIAL TO MY BROTHER THAT HE SUBMITTED TO YOU AND ‘FORGOT ALL ABOUT ME’,
HOW COME HE NEVER TALKED ABOUT YOU…? HOW COME IT WAS ME HE CAME HOME TO EVERY
NIGHT? YOU MIGHT HAVE TAKEN ADVANTAGE OF HIM BUT YOU TWO NEVER HAD ANYTHING!”
 Papyrus taunted cruelly, a snarl twisting his face.
Grillby growled and ripped the bone out with a sound like crackling flame and
flung it at Papyrus with disdain as he lashed out again with stronger flames,
actually feeling some killing intent now, his flames flaring out further.
Grillby considered throwing Papyrus’ abuse of Sans in his face, but he was
quickly going past the point of talk, he wanted to kill.
Sans was slightly taken aback by how Papyrus and Grillby seemed to be fighting
over him which had him flushing slightly. He liked Papyrus fighting for him, it
made his soul feel warm. He started edging around the inner wall to get a
better look at his brother, hoping he was unharmed.
The bone Grillby flung back at Papyrus hit him square in the face, making the
crack in his skull worse. Papyrus fell to the ground, magic disappearing from
sudden weakness. He felt like he just had the wind knocked out of him. He was
dizzy. He quickly tried to recover but it wasn’t fast enough.
Grillby saw an opening and lunched forward with a gleeful laugh, his flaming
lashes flickering out to take out the annoying gnat before him, only to be
startled when his flames ricocheted off of small red bones, he whirled to see
Sans standing outside the barrier, glowering at him, his left eye glowing
crimson and full of hate.
“oh no you don’t!” Sans snarled with seething hatred hissing between his teeth
as he reached out with a hand, gesturing curtly and holding Grillby in place
with blue magic on his soul.. “you be good and let my brother teach you your
place. get him, papy.”
Grillby froze in place, first with the shock of seeing his attack reflected,
and then physically trapped as the color of his soul was changed, gravity
trapping him. His mind went awhirl, very confused by everything he was seeing
and hearing. Sans defending his brother, calling him anything other than boss,
threatening him...
That stalled enough time for Papyrus to regain his strength. He leaped up from
behind the bones, whip in hand, and cracked it over his neck while with his
other hand, conducting a storm of white bones down upon him. “GO TO HELL…” Was
all he could say.
Grillby whirled to face the attack, but too slow. He started to lash out with
his flaming whips but stumbled when he was hit in the neck, falling to one
knee. He only had a chance to snarl before he was destroyed.
Papyrus  wiped the dust from his jaw, the crack along his eye became bigger. He
stared at all that remained of the flame elemental for several moments with a
blank expression before a triumphant smirk, his teeth parting in a pleased grin
as he turned to face Sans.
Sans found himself cheering as he saw the Imp crumble to dust and he wanted to
rush into his brother’s arms, but he had to wait for Papyrus to dispel the bone
barricade.
“you were amazing papyrus!” Sans applauded with admiration. He all but jumped
in place before he thought of a way to thank his brother and he dropped his
eyes submissively. “i think i need to thank you for…proving your ownership…” He
added shyly but with a small smirk.
Papyrus grinned as he dispelled the bones and made it to Sans’ side in two
strides and pulled his brother in for a heady kiss. Sans moaned into his
brother’s kiss, wrapping his arms about his brother’s shoulders happily.
Papyrus slowly pulled back, “YEAH...DON’T MENTION IT…” He smiled weakly.
Sans could see some uncertainty in his brother’s eyes and was determined to
ease it, he all but threw himself into his brother’s arms, wrapping his legs
around his brother’s hips and kissing him hungrily.
“i love you, papyrus.” He breathed between kisses before lapping at his
brother’s teeth. “i love you most.” He added as he moved to nuzzle Papyrus’
neck.
Papyrus’ cheeks flushed red and he returned the kiss. “I love you too… LET’S GO
HOME AND...CELEBRATE.” He chuckled a little, sounding more confident and happy
as he carried Sans home.
Sans almost purred at his brother’s decision and allowed himself to be carried,
relaxing completely in his brother’s hold, feeling safe.
“You were my first….” Papyrus suddenly muttered, so softly as if he hoped Sans
didn’t hear him. Sans glanced up at his brother with a startled squeak, feeling
a little embarrassed, but quite pleased by the admission. He’d been his baby
brother’s first, and hopefully his baby brother’s only lover. Sans leaned up to
kiss Papyrus eagerly, tightening his embrace and rocking his hips frantically
against Papyrus. Hearing that he was his baby brother’s first enflamed him more
than he could have ever imagined. He also felt a sudden possessiveness well in
his soul for Papyrus and he started to say something when Papyrus broke their
kiss to continue hesitatingly.
  “…..how many others have you...been with…?” Papyrus asked in a low tone, but
more audible than his barely whispered confession. Sans felt a little caught
off guard by the question and he flushed bright red and ducked his head. he was
not prepared to discuss this, but his brother deserved absolute honesty. And
Sans could tell that he was trying to sound like he did not care, but Sans just
knew that it was eating his brother up inside, Sans was not sure why, but then
he remembered his brother’s whispered comment about Sans being his first and
realized that Papyrus was jealous and maybe thinking that Sans was not taking
this as seriously as he was. Oh Papy….
“i…i’ve been in love with you for years, pap, like, head over heels and sick
with longing for you. but…i never thought you….would ever return my feelings.”
He started softly, embarrassed. “and…well, i was in heat…my first heat, it
caught me really off guard, you know? no one goes into heat anymore...i’ve been
so confused, but going into heat every other month...and it was driving me
insane.  i got drunk because…i was hoping to be unconscious so i would
not…throw myself at you,..that was the first time grillby suggested i could pay
my tab with….additional currency. he was my first.” Sans was ashamed and a
little angry, realizing that Grillby had taken advantage of him when he was
extremely weak and not thinking straight.
“i…thought of you at the time though…i…never wanted him, i wanted you.” He
added, ducking his head and hiding his face in his brother’s shoulder. After
pausing for a moment he continued.
“some…of the dogs...well, doggo caught me at the sentry station while I was in
heat once...he….uh...helped me through it that time...and now he seems to think
we have a thing...the others just....threatened me…i never had sex with them,
but they would….make me blow them.” he mumbled, hating how weak and easily
manipulated he was. “i’m sorry pap….” he almost sobbed. “i never wanted anyone
but you!”
Papyrus blushed, he wasn’t expecting that answer at all. When they got inside
their house all he could do to respond was to kiss him passionately. He was
furious about the dogs though. He questioned if he could murder other guards
and get away with it. Probably.
“I’VE LOVED YOU SINCE WE WERE CHILDREN, SINCE WE WERE STILL IN GASTER’S LAB….”
He admitted as he pulled away from the kiss slowly. Sans was a little surprised
to hear that, when they had been in Gaster’s lab, that had been 20 years ago.
Papyrus had not even been an adult yet, and Sans, well, Sans had been somewhat
infatuated with their father at the time. Completely devoted, slavishly so.
He’d adored their father. Not that it brought him anything but pain, but he had
simply not been able to help himself, his father had dazzled him, and made him
feel so good...he shook his head violently.
Gaster was gone. Papyrus was here. Papyrus was all that mattered. He had
Papyrus, and Papyrus had him, and they loved each other. And Papy had just
killed someone. For him. He cuddled closer to his brother’s chest. After
hearing how long his brother had loved him, he almost wept. For years and years
they had both loved each other, they had missed out on so much time that they
could have been together. Well, no more missed opportunities.
“then we have a lot of time to make up for, brother…” he breathed lustfully,
his eyes lights glowing a soft red and shaped like hearts. He began to run his
fingers lightly over his brother’s neck and down his scapula before trailing
his fingers back up, pressing into Papyrus’ vertebrae slightly harder, trying
to ease the remaining tension he could feel there.
Papyrus shuddered and eagerly carried him to his room. He dropped Sans on the
bed and eagerly clipped the leash to his collar. “NOW THAT YOU’RE MINE I CAN’T
LET ANYONE ELSE HAVE YOU, TOUCH YOU, LOOK AT YOU. I’LL KILL ANYONE THAT
THREATENS THAT…” He grinned darkly and ripped his brothers jacket off. “YOU’RE
MINE SANS, AND I’LL NEVER LET ANYONE ELSE HAVE YOU UNLESS I’M DEAD.” He
hungrily kissed him, summoning his tongue and lapping his brothers teeth and
neck.
Sans loved his brother’s dominating attitude and did not struggle at all, even
though the leash surprised him slightly, but he found himself flushing red as
his brother claimed him. He allowed his brother to pull his jacket off and then
fell forward onto his hands and knees looking desperately up at his brother and
then keening softly when Papyrus began to kiss him.
“yours, papy, always yours!” Sans vowed, leaning up into his brother and
returning the kiss hungrily. He allowed his brother’s tongue to dominate his
mouth, tasting him, running over the roof of his mouth and the backs of his
teeth, simply moaning his pleasure.
Papyrus was obviously pleased with his submission. His eye light flared red
creating magic in his pants. “Of course my precious brother…” He purred as he
leaned down to kiss him again before continuing to strip him fully. “Now...tell
me what you want. Beg for it.” He unbuckled his pants slowly.
Sans moaned low in his throat as his brother pulled away and then his eyes
dropped to watch his brother’s hands unbuckle his pants hungrily, unconsciously
rocking his hips. He had been dripping wet with need since seeing Papyrus dust
Grillby, and he was drooling at the thought of having his brother’s cock again.
“i want….your cock, brother…” he moaned, his eye lights flickering into heart
shaped as he panted wantonly. “i want you to fill me with your cum!”
Papyrus grinned, his erection sprung from his pants, it twitched in excitement.
His hand gripped the leash tight while his other hand wandered looking for the
riding crop he kept nearby. Once found he smacked the bed hard the touched
Sans’ face with the tip of it. “Such a good boy… Shall we begin or should I
torture you a bit more~”
Sans was slightly annoyed that his brother wanted to waste time with teasing
him instead of fucking him, but decided to let his brother get his dominating
rocks off. He rubbed his face against the riding crop slightly, wondering in an
off hand manner if it would feel nice to get smacked with the crop in his
dripping pussy. He turned his eyes up to his brother and smirked.
“whatever you think I deserve, boss…” he teased, his voice slightly husky.
“Mmm...very well then.” With Sans off guard papyrus forced his cock into his
brother's mouth and started thrusting him, forcing him to deep throat. He held
his head in place so he couldn’t move from the pain or lack of air. Sans made a
small squeak of surprise that was quickly turned into a gurgling gasp as his
brother shoved his length into his mouth. He quickly conjured a tongue and
throats and tilted his head up slightly as he tried to swallow around Papyrus’
cock, moaning softly as his eye lights rolled back in his head and drool began
to run down the corners of his mouth. He loved the taste of his brother, the
weight of him on his tongue.
He was starting to drip juices down the insides of his femurs and he reached a
hand back to start desperately fingering himself, he felt so empty, he needed
relief.
The crop smacked the back of his hand “I didn’t give you permission to touch
yourself.” Papyrus growled as he thrusted down harder, deeper. Papyrus then
moaned softly in pleasure, happily watching his brother be tortured
Sans whimpered with frustration as he pulled his hand reluctantly away and his
placed it back on the bed. He started to look pleadingly up at his brother
until he began to thrust harder; Sans eye lights rolled back again and he was
starting to feel light headed from the pressure in his conjured throats.
Papyrus grinned as he fucked his brother's face, panting in pleasure. “You’re
behaving so well I might just have to bend you over and fuck you properly~”
Sans whined in need at his brother’s words, bucking his hips at the thought of
being filled, of being fucked, his inner walls clenched around nothing, and he
almost sobbed with frustration and he began to suckle harder on his brother’s
cock as he looked up at him with a pleading expression.
“Very well…” Paps pushed him down on the bed and slid his length deep inside of
him. He gasped out feeling his soaking brother squeeze his member. “S-SANSS~~
AAAHHH!!!” He jerked the leash as he started to fuck Sans faster.
Sans keened in pleasure as he threw his head back, before being pulled forward
by the leash. He wrapped his legs around Papyrus’ hips and his arms around his
shoulders, panting in pleasure, his tongue hanging from the corner of his
mouth.
“y-yes…broth-er…so….big…!” he gasped.
Papyrus tugged the leash as he fucked him recklessly. “Scream my name slut! Who
do you belong to!” He bit down on his neck hard, his penis thrusting in and out
as fast as he could.
Sans gasped as his brother sped up and tried to meet his thrusts as best he
could. “pa-py, pap-y-rus! I be-long to y-ou, pa-pyrus!” He gasped as best he
could between long moans. “uhhhn….harder, papy!” He gasped frantically as he
bucked wildly against his brother, trying to angle himself so that Papyrus hit
his G-spot. “so big, so good papy!”
Papyrus found his way into Sans’ g-spot and kept going. He was getting close.
He had no intention of pulling out though. He held down his wrists and kissed
him, shoving his tongue deep down his throat as he came inside, his cum
sticking to the walls of Sans’ vagina, filling him.
Sans shrieked when Papyrus found the bundle of nerves at the back of his magic,
and began gasping and writhing with overstimulation, his eye lights rolling
back and he arched his spine violently, pressing his pelvis as close to his
brother as he could, panted with pleasure, moaning his appreciation until his
mouth and throat were full of his brother’s tongue. He tried to cry out with
his own climax when he felt Papyrus cum inside him, his voice muffled by his
brother’s tongue. He shuddered through the biggest orgasm of his life, tears of
release trailing down his cheeks and he suckled his brother’s tongue.
“Such a good boy… My good boy...” Papyrus kissed him rewardingly and he slowly
pulled out, a long trail of cum oozed out of Sans. Papyrus cuddled and cooed
his brother, actually in the mood to show off his affection, probably because
of all the shit they went through. “My Sans…”
Sans had not expected his brother to be so affectionate, even after sex, but he
was not about to complain, not when he had been wanting such affection for
years, starving for it. He curled happily against his brother’s chest, nuzzling
his neck, licking his vertebrae softly.
“i love you, papyrus…” he breathed softly, almost not believing his luck.
Papyrus hesitated for a moment before whispering, “I love you too Sans..”
Papyrus was tired after everything that happened today. The nightmares, the
fight, the sex.. Before Sans could even notice he fell asleep with his brother
in his arms.
Sans slowly blinked open his eyes from where he had been dozing when he felt
his brother relax completely against him, and blinked slowly in shocked
amazement to see that Papyrus had felt secure enough around him, safe with him,
to have fallen asleep. He felt his soul swell, he did not think he could have
ever loved his brother more...he cuddled happily against his brother about to
follow him into sleep when he remembered his brother’s nightmares and reactions
to being seen weak, his REVULSION to being seen as weak, something Gaster had
obviously instilled in him.
He did not know why his father had ever done something like that; he had never
done that to Sans...he had mocked Sans (almost teasingly) about how weak he
was, and he tried to make Sans stronger, but he never did anything to instill
fear of being seen as weak in him. Sans felt a flush cover him, shame and
arousal and guilt. He had not thought of his father in years. Which in one way
felt like a betrayal to his first love, but thinking of him now felt like a
betrayal to Papyrus. He rubbed his temples, fighting off an impending headache.
He had to focus on Papy. Gaster was gone and never coming back.

 He pulled away carefully from his brother and slowly sat up, struggling to
think through mind hazy with exhaustion and post-coital bliss. He looked
thoughtfully at his brother’s scarf and decided that it should function as a
suitable blindfold, and used some blue magic to summon it to himself with a
huff of laughter before looking for something to block his hearing. They did
not have earmuffs or earplugs or anything like that, but after a long moment he
saw some headphones, earbuds really, that should work well enough and used some
blue magic to bring them over too.

 He carefully placed the earphones in his ear canals and then wrapped the scarf
securely over his eye sockets, and then curled happily against his brother,
following him into sleep.
---

Papyrus slept very soundly that night. Though the night mares still lingered,
they always did even when he slept well, though they were getting darker. Yet
darker…until disembodied hands with holes through the palms reached out for
him; until he was grabbed and dragged away from Sans. He shrieked out for help.
He tried to wake himself up but he couldn’t; for he was already awake.
Chapter End Notes
     Enjoy the fluff while it lasts!
***** Nightmares from shadows *****
Sans slept soundly that night, safe in his brother's arms, nightmares kept at
bay as he felt his brother's soul thrum in time with his own, and he was happy,
adrift in a sweet fantasy of safety and peace. His dreams were vague, fleeting
images, but nothing that really left an impression on his mind, and he just
slept. His sleep was so restful that for once his magical reserves began to
recharge. It was as though his soul knew before he did that he would need the
boost, that he was going to be in danger and need the reserves.
But although he did not wake up when Papyrus vanished, his dreams abruptly
became troubled with violent flashes of violet and red, jagged shapes pressing
around him, shadowy tendrils capturing him, and he finally came awake all at
once at dawn with a strangled scream, tears pouring down his cheeks. He
carefully pulled off the scarf and looked around desperately for his brother,
whom he knew on an instinctual level was gone even before he had woken up. He
carefully removed his headphones.

 Papyrus was indeed no longer there. He stared blankly at the spot where his
brother had been, eye lights shrunk to pinpricks and he reached out a trembling
hand to touch the bed beside him. It was cold, Papyrus had not been there for
hours. Sans bit back a small whimper as his mind whirled. He thought for a
moment that Papyrus had left early for work, but....he looked down at the scarf
in his hands, looked to see his uniform and battle body still in a pile on the
floor. No, Papyrus could not have left for duty, not naked...not without saying
good bye. Maybe he had had nightmare and was outside again? Or just downstairs?

 He shortcut into the living room, no one was there.

 Shortcut outside. No Papyrus.

 He began to feel panicked. He shortcut to his room, pulled on a oversized red
t-shirt, some track pants, grabbed his coat, but did not bother with socks or
shoes. He was frantic.

 He began to shortcut to any place Papyrus may have gone.
Sans’ sentry station.

 Their private sanctuary in Waterfall, a little cave surrounded by Echo
flowers.

 Undyne's house (although he did not dare enter or even let his presence be
known).

 And finally...soul pounding, fear lodging in his throat, his last
hope...Gaster's lab.

 He stood at the entrance, exhausted from so much magic usage, terrified,
sweating with fear and overused magic, his hands gripping tightly to the bottom
of his hoody.
Gaster was gone, spread across time and space, right?

 But...was he really?

 Hands shaking he slowly pushed open the door, the hinges squeaking from lack
of use and he winced, his eye sockets going black and he felt a chill travel
down his spine...he had a horrible sinking feeling in his soul. This may not
have been the best plan...but he needed to find Papyrus. No matter the cost, he
had to save his little brother.

 He slowly entered the lab, only making it in two steps before freezing in
place, trembling.

 "p-papyrus? Boss?!" He called into the darkness, his voice wavering only
slightly.
The door slammed shut behind him. He heard the lock slam home with a deafening
finality. It was dark. Sans instinctively backed up in the darkness, one hand
reaching for the doorknob before falling away, knowing it was useless and he
began to breathe heavily, eyes darting around frantically, looking for Gaster
and he tried not to show how terrified he was. He tried to appear brave as he
stepped forward hesitatingly.
"It's alright Sans. Daddy's home now~" A deep, slightly husky voice seemed to
whisper in his ear, echoing through his mind strangely; Sans made a strangled
gasp and flinched away, eyes frantic even as his body reacted to the familiar
tone with a needy warmth starting in his bones.
In the darkness further away from him came the disembodied voice again. “You
know, I never understood why you call your baby brother 'boss'. I would have
thought you were the one who would have taken charge after I...vanished. If I
can even call it that.” Gaster’s mouth twisted with wry amusement, although it
did not reach his eyes; he was anything but amused.

 "i...you know why i defer to him..." Sans sputtered, almost in tears. He
remembered once, when he was very, very small, a baby-bones, before Papyrus had
been created, when his father had been, affectionate; very
affectionate...almost doting on him, spoiling him. But Gaster had become
increasingly unstable, and increasingly obsessed with 'fixing' his mistakes.
Sans shivered and tried again, looking at the floor, ashamed of his weakness.
"i call him boss because he's...stronger than i am...the...you know how...much
a failure...i am..." He muttered angrily, but also a little sadly, he did not
want his father to think he was weak, he wanted to please his father...
Wait, where had that thought come from?
“Oh Sans. My darling boy. You were never a failure except in your own mind, and
do you think I'm stupid? You think I don't know why I was scattered across time
and space Sans?"

 He flinched when Gaster continued to speak and looked up in shock. "i never
thought you were stupid fa-...gaster..." he said in shock, still refusing to
use the familial term although it had almost tripped off his tongue. "whatever
i may think of you...i never thought you anything other than brilliant, you
created the core for fuck's sake!" he ignored his father’s question, it had
seemed rhetorical. Besides, his mind tried to repress that memory of the
incident...of his involvement. But his soul twisted and ached with guilt and he
began to twist his phalanges together nervously.
"SHUT UP SANS! THAT'S NOT WHAT I MEANT!" His father formed in front of him and
grabbed him by the throat. "YOU FUCKED WITH MY MACHINE! YOU TRIED TO GET RID OF
ME! And it worked for all these years but I fixed it and I have no intention to
leave my family again." His grin was evil. A purple tongue slowly glided up the
side of Sans' cheek.
Sans' eye lights sputtered out when his father reappeared in front of him, his
hands desperately scrambling at his father’s wrist and he let out a strangled
squeak of shock at his father's appearance and he could not stop the shiver
that rattled his bones. His father looked....different, partially melted, but
still substantially himself. He bit back a moan of pleasure as his father
roughly shoved him against the wall, but although his body was reacting with
lust to his father his mind was racing in fear.
Sans tried to shake his head in denial at his father’s accusation, closing his
eyes and turning his head away when his father licked him, frightened by the
sensation, his body’s betrayal of his will.

 There was a horrible noise in the distance and the room went cold. In a room
downstairs Sans could hear the faint sound of Papyrus screaming. And as he
heard his brother scream and all other thoughts fled.

 "where is papyrus?!" He growled, eyes glowing red in rage as he turned his
head back to meet his father’s eyes, furious. He bared his fangs fearlessly,
ready to fight.

 "Oh your brother? I'm helping him with that terrible condition I had to leave
him with... I left in the middle of an experiment with him." Gaster explained
in an almost bored tone, seeming amused by Sans’ anger and Papyrus’ pain in
equal measures. He seemed cruelly pleased by the irony that Sans had tried to
get rid of Gaster in order to protect his baby brother, only to indirectly be
responsible for his current predicament.
Sans could hear Papyrus was screaming in desperation, Sans has never heard
anyone scream like this before.
"you...what? what are you doing to him?!" He asked in a trembling voice. He
also felt horrified and sins crawled up his back, if what his father said was
true, than Papyrus had been suffering for 20 years from whatever unfinished
work Gaster had done to him...Sans had done that to Papyrus, caused him
unnecessary harm when all he had wanted to do was protect him...he felt ill. He
felt lower than dust. He felt like crawling into a hole and falling down. He
felt like curling into his father’s arms for comfort...Sans shivered, fighting
the urge to do just that.
Gaster grinned at him with pride, as though he was pleased that he asked. "Why
tell you when I can show you? But I'll only show you on... One condition..."
His eye light flickered a dark purple as the ran down Sans’ form with a eerie
intensity.
Sans trembled as he looked first up at his father and then in the direction of
Papyrus' screams. He was terrified of what the condition could be, various
horrors whirling through his mind. But it was no decision. He went submissively
limp in his father's hand and nodded.
"a-a-anything....please...take me to....papyrus..." he whispered, closing his
eyes in defeat.
"I want you the way your brother has been having you..." Gaster purred hungrily
as he pulled Sans closer by his neck. Sans eyes shot open in shock, his eye
lights first dilating in disbelief before sputtering back out and he trembled,
red tears already pooling in his eye sockets, his face flushed a bright cherry
red. He had not been expecting this, of all things…How had his father even
known that he and Papyrus had....they'd only been together a couple days!
Had he been watching them? And if he had...how had he not contacted Sans before
this? Sans had missed his father so much!
The thought hit him like a guilty punch to the soul and he looked to the side,
trying to hide his hurt expression, knowing his father would only manipulate
him with his own pain if he knew. He also wondered a little guiltily if his
father had known how much Sans had used to pine for him, if he knew that Sans
had always been in love with him. He found himself flushing an even brighter
red that began to travel down his neck and coloring his ribs -his soul starting
to glow through his shirt- with embarrassment and tried to pull away until he
was pinned to the wall and Gaster forced his tongue into his son’s mouth. His
hand trailed along his back in a loving manner. Black tendrils coiled around
Sans' wrists and ankles, holding him to a wall
"You will be good for Daddy won't you?" He cooed sweetly with his voice ringing
in Sans’ head.

 Sans whined helplessly as his father molested him, knowing that fighting was
useless. And to his shame his father's domination of him was starting to turn
him on and he could only hope to hide his reaction as long as possible. He
pressed his femurs tightly together and went limp in his father's tentacles
"Such a good boy, Daddy is going to take good care of you from now on." Gaster
promised with a low growl that had Sans bucking his hips reflexively, his face
bright with shame. Several floating hands were summoned and grabbed Sans. A
pair of tentacles wrapped around his legs, starting from his ankles and winding
up until the were halfway up his femurs, underneath his shorts, stroking
gently, squeezing. They slowly spread his femurs apart, making the glow in his
shorts clearly visible. A pair of hands held his hands above his head. A third
hand began to lift his shirt while a fourth began to trail almost lovingly
along his ribs. The hand then tightened around his lower rib, pulling slightly,
causing a low desperate moan to burst from Sans although he tried to stifle it.


 Gaster seemed very pleased by his response, his eyes half-lidded in lust as he
summoned his cock, the magic he formed was purple and the cock was bigger than
Papyrus'. He let Sans stare at it in bemused lust for a moment before he had
his tentacles pull Sans down so that he was on his knees on the floor, and one
of the hands grabbed him by the back of his neck to force his mouth onto it.
 Sans instinctively fought against his father's grip when he realized that he
was being unfaithful to Papyrus, Papyrus would hate him!

 "wait- i can't-papyrus!" he tried to explain before his father’s actual hands
pried his mouth open and forced him to suck.  He was forced to swallow his
father's length, he gagged momentarily at the unfamiliar girth (he was so big)
and his tongue and throat automatically formed without his having to even think
about calling his magic.
Gaster let out a small moan and he continued to hold his son close, bucking
into Sans’ mouth.

 Hearing his father moan above him, before he'd barely done more than swallow
the cock had Sans feeling a sense of accomplishment, it was almost like praise,
and he shut his eyes in shame and began to suckle even while tears dripped down
his cheek bones.

 He could not help it, Gaster tasted so good, he was so warm and heavy in his
mouth, so thick.
"Good boy Sans..." Gaster whispered, cooing at his son. "if you keep this up I
might make you my bride... No more experiments, no more hurt, just pleasuring
me on command. My beautiful son... How does that sound?"

 As if the prospect of having Sans at his every whim was turning him even more
on, Gaster’s member twitched in his mouth, he had even started to pre-cum a
bit, it tasted so good. He slowly pulled his length out of his son's mouth to
hear an answer.

 When Sans had been very young, before he had been driven to feel hate that
equaled his love for his father (but still, even then) he had worked himself
tirelessly in order to gain his father's praise, and even now, just the
smallest amount had him feeling wet and his hips twitched as his pressed his
femurs tightly together, still feeling ashamed by his body's evidence of
betrayal. He was beginning to feel heated, and he felt so empty, he needed to
be filled.

 He found himself staring up at his father while he spoke, his eye sockets
glassy with unshed tears and lust and he had to admit, the offer was tempting
and when his father began to leak precum into his mouth he could not help the
desperate moan that he  made as he suckled harder, or the small moan of
complaint he made when Gaster pulled out. His father’s magic tasted so good, it
had a stronger taste than Papyrus’, less spicy, more musky. It went straight to
his head and to his groin and he wanted more.

 He gasped shallowly, trying desperately to remember what his father had asked.
It was important...He flushed bright red, ashamed still further by how he was
reacting, this was his father, his own father! He may have been in love with
him, and fantasized, and his father had touched him when he was little but...it
was still wrong wasn’t it? At least, he thought it should feel wrong, but his
soul was straining, eager for his father’s touch.
His mind whirled in panicked circles, thinking frantically for any reason to
refuse, but then he thought of his brother, Papyrus....he made a desperate
gamble.

 "papy too, please? we can both make you feel  so  good....if...you let papy
too...i'll never deny you...never refuse you..." he swore breathless, looking
up with desperate eye lights. “please, daddy?”
Gaster grinned broadly at Sans' negotiation, looking absolutely delighted. "Of
course Sans. I would love to fill both of my sons with my cock. But first I
want you to show me how good you can be..." The tendrils spread Sans legs open,
a disembodied pair of hands all but ripping Sans’ shorts off, and Gaster licked
his teeth hungrily when he saw the evidence of Sans’ arousal. He had not yet
formed anything, but his magic was coiling in a heavy swirl in his pelvic
girdle.
Sans almost could not believe how easily his father had agreed, and despite
himself, the thought of his brother and him being with their father without the
pain of constant torture, of no more experiments, of just being with their
father, even if he was...using them as sex toys, had him feeling relaxed and
pliant.
Gaster shoved his huge cock into Sans' pelvis hoping this would trigger him to
making a vagina to penetrate. "I love you Sans... Please tell Daddy you love
him too? I need to know how much you want me." His father's lewd words had him
squirming and feeling hot. So when his father began to penetrate his already
swirling magic it coalesced almost immediately into a dripping pussy and he
gave a small squeal at the sensation and turned his head away in embarrassment.

"D-daddy..." Sans gasped wantonly. His daddy was so big...
"Look at daddy when you're talking to him Sans.. I've taught you better than
that." He kissed him tenderly. His cock was way too big for Sans' cunt but
Gaster obviously loved how tight Sans was around him. He could feel it
stretching over his length trying not to break, the thought of it breaking only
made him thrust harder, faster, grabbing Sans throat.

 Sans writhed on his father's length, whining helpless as his magic tried to
adjust, the length reached the base of his floating ribs, filling him so
completely, his eye lights rolled back as he rolled his hips desperately,
loving the pain of being overfilled, the stretching. He gave a small gasp and
tried to meet his father's eyes as he trembled.

 As his father began to thrust into him, he gave a high keening cry and tried
to shift his legs, wanting to wrap them around his father's hips to pull him
deeper, so desperate to be used. It felt so good, so good. Like he had been
made for it, his father filled him so good...

  He was such a slut...

 "d-aa~dddy" he keened with pleasure before one of his father's tentacles
slipped into his mouth. Mindlessly he began to suckle the appendage as he tried
to maintain eye contact, his hips trying in vain to meet Gaster's thrusts.
Gaster trembled as his son sucked on the tentacle, it was equally as sensitive
as his cock. He summoned another, sliding it into his ass, triple penetrating
his son. "Y-yes..." He trembled "Daddy's here... Keep calling my name..."

 Sans was not expecting the third tentacle and writhed, first trying to avoid
the penetration, scared of the pain he thought it would bring, but then
shifting his hips back to accept the intrusion, giving a small mewl of pleasure
as he realized that it added to the feeling of being filled. He thought he
could easily become addicted to this, it felt so good.

 "Daaaa-mmmmmnn" He moaned around the tentacle in his mouth, attempting to obey
Gaster.
Gaster grinned, fucking his son harder. He was about to hit his climax. Cum
squirted out of his cock all inside of Sans’ walls. Mid way through cumming
Gaster pulled out and squirted all over Sans' face and ribs. Cum leaked out of
his vagina and dripped down his whole body. "You belong to me again...." He
assured, claiming his son as his property

 Sans mewled at the feeling of being filled, but when his father pulled out he
could not stop the small wail of loss that he made, his vagina walls clenching
as if trying to pull him back in, and he writhed, wanting his own orgasm, and
he gave his father a desperate, pleading look as he sucked harder on the
tentacle in his mouth.
"Aw, you wanted to orgasm as well? Very well. I will reward you with that." He
calmly slipped two fingers into Sans' vagina and started fingering at the G-
spot with max speed

 Sans threw his head back and wailed around the tentacle in his mouth, his hips
rocking frantically and his legs trembled. Every time his father hit his G-spot
he squealed and he did not care in the least that he sounded like a total slut,
it felt so good, he wanted it to never end, but finally he  reached his climax
and came apart in his father's hold, absolutely wrecked, drool leaking down the
corners of his mouth, eyes staring unseeingly at the ceiling, and he went limp.
Gaster pulled away his hand covered in Sans' come. He simply licked his hand
clean and collected himself. "Shall we go see your brother then?"

 Sans tried to focus on his father, still dazed. That had felt amazing. He
blinked slowly, coming down from his post-coital high slowly as Gaster lovingly
stroked his cheek. He all but purred at the affectionate touch, nuzzling his
daddy’s hand and he was about to respond lazily when he jolted upright when he
remembered what his father had said earlier about his brother’s condition.

 "you said...he...was..." He tried to focus and shook his head, his scientific
mind whirling. "he was in the middle of some experiment. i...want to help
you...i don't want him to die. i want us to be together...for a long, long
time..." he looked up at his father shyly, a small flush over his cheek.
"i...don't want to hurt him...but...i want him to be healthy..."
Gaster looked over his son unamused. "You are not to interfere with my
experiment Sans. This is an important and very secret experiment."

 He opened the door to the basement. Papyrus was still screaming and crying. He
was strapped to a machine naked. He had the same cracks Gaster has in his face
and the same holes in his hands. His body looked broken but it wasn't. He
looked up and Sans and Gaster and frantically started speaking in wingdings.
Gaster understood every cry for help but Sans was rusty when it come to
wingdings

 Sans flinched back and huddled in on himself, looking down at the floor with a
scowl, angry at himself for making such a presumption.

 "i'm sorry, daddy..." He apologized meekly. "i just..." he trailed off, trying
not to cry. He was such a fuck up, his father knew it as well as he did. He
reached up to grip his collar tightly, letting the spikes dig into his hands
hard enough to draw marrow, embracing the pain as he wallowed in self-hatred.


 He automatically trailed after his father, leaving his shorts abandoned on the
floor, not bothering to clean any of his father's cum off of himself, barely
aware of his surroundings.

 He looked up numbly when he heard his brother's desperate cries, his eye
lights flickering as he tried to pull himself out of the depths of self-hatred,
his mind hazy. He could  barely understand wingdings, it had been too long.

 When he was finally able to focus he blinked, blinked again, and looked
between his brother and father. He wanted to ask what his father had been
doing, but was terrified of receiving another rebuke. He shivered and although
he wanted to approach his brother's side, comfort him, he just huddled in his
father's shadow, feeling shame make his bones rattle.

 All his prior confidence just, drained out of him, and he could feel nothing
but shame, weakness, how inept and worthless he was. He almost collapsed under
the weight of his own sins as he tried not to sob.
Gaster grinned at his creation and started speaking in wingdings. Papyrus
looked emotionless. He obeyed every command, Sans just couldn't understand it.


 "Yes excellent Papyrus.... Now.... Let's see what happens when I..." He pulled
a lever and electricity flowed through Papyrus. He screamed out again, his body
started to melt in a dark goo and slithered away, just like Gaster can. Gaster
seemed pleased. Sure he got out of the restraints but it was okay. Papyrus
couldn't escape this lab without dying.

 His brother's scream of pain finally knocked Sans out of his cycle of self
hatred and he came to himself with a jolt, eye lights flickering frantically as
he watched his brother seemingly melt. Was Gaster trying to turn Papyrus into
whatever he was now? Sans trembled, not knowing how he felt, but only sure he
did not want his brother to be in pain. Without realizing it he shortcut to his
brother's side, tried to gather him into his arms.

 "papy, i'm here..."
Papyrus frantically grabbed onto his brother. Sans returned the embrace of his
brother just as frantically, trying to hold him together.

 Gaster hissed and stormed up to them. "Sans get off of your brother! You're
interfering with his tests!" He back handed sans across the face. Sans  cried
when he felt himself be ripped apart when he was backhanded by his father, his
father who had only a few minutes ago embraced him so tenderly, made him feel
loved, wanted...he clutched his phalanges to his head as his mind tried to make
sense of what was happening, he was so confused, so lost.
"His body is very fragile right now he can't die until after I'm don—..." He
quickly cut off what he was saying. "Sans go upstairs."
Sans mind whirled.

 He loved his daddy.

 He loved his brother.

 He lusted after both...

 And...

 Hadn't daddy said they would all three...

 "d-d-...daddy?" He whimpered. "you-you said...we three...would be
together...you..." he started to hyperventilate, his magic flickering wildly
around him, he fell limp against the floor, so tired, too tired to make sense
of what was happening.

 He stared blankly at his brother, his mind hardly focusing on his father's
words, he attempted to obey his daddy, desperate for praise, but he was so
tired...so very tired...

 "pa-papy...daddy...please..." he felt himself losing consciousness, his hand
reaching for Papyrus and tears poured down his cheeks even as everything went
black.
***** The choice that shatters a soul *****
Sans’ consciousness drifted in darkness and he felt as though he was sinking
into sludge, and the more he struggled the faster he sank. It was thick, cold
and oily, and he felt as though he would never be clean again. The thick liquid
invaded him entirely as he was without any protection, his skeleton bare. Every
orifice was filled, his eye sockets, his mouth, his nose...his soul. He tried
to scream in fury and fear as the viscous fluid invaded his soul, but he just
choked, and it began to burn as he wailed in pain.
And then he had fallen onto some solid surface, the coils of chains tightening
around him, choking him as horrific images flashed before his eyes, too quick
for him to recognize but enough for his subconscious to pick up on the
impressions of tortures. He tried to struggle, to escape, but to no avail.
Every movement just tightened to coils around him until he could no longer even
breathe, and then they kept tightening, wrapping around his soul, as he
crumbled to dust...Papyrus in the distance...just watching.
Sans came awake with a sudden stifled cry of fear, his eyes frantic and
unseeing, and he trembled with repressed panic from a nightmare; he was
trembling, tears pooling in his empty eye sockets before trailing in red
streaks down his cheeks as he tried to figure out where he was. His breath
coming out in frantic pants, and he slowly realized that he had woken up in
what he could only assume was Gaster's make shift bedroom. He was on an old bed
with wool blankets. It was actually quite comfortable. Gaster was next to him
cuddling him close, evidently waiting for him to wake up, Sans slowly looked up
at his father, he noticed in the back of his mind that he was wearing nothing
but his t-shirt, but he did not feel shy.
"Shh, shhh, pet, you had a nightmare. You're safe, nothing will hurt you..."
Gaster held his son close, voice low and soothing.

 Sans blinked slowly, trying to calm his racing soul; desperate for comfort he
turned and burrowed into his father's chest without shame.

 "daddy…! daddy..." he whimpered, barely coherent as he clung to his father.

Gaster kissed his son's forehead "there there... I'm here. It was just a bad
dream..." he cooed, his voice still low and soothing, seeming to wrap around
Sans as he felt himself calming down.

 Sans all but climbed into his father's lap, shivering, allowing himself to be
comforted and he slowly relaxed although his soul felt heavy. He just lay limp
in his father’s arms, enjoying the soothing hand that ran gently up and down
his spine as he allowed his mind to put the recent events in order, discard the
nightmare, and prioritize his concerns. It took several minutes of silence
before the most important thing occurred to him.

 "daddy...did you lie about papyrus? about the three of us being together?
i....i promised to do anything for you for him...please daddy...i love him so
much-" he stopped himself mid plea with a startled gasp, eye lights flickering
up quickly to his daddy's face before skipping guiltily away and he flinched as
waited for his daddy to punish him as he deserved, trying not to sob as his eye
lights went out.

 His daddy would strike him, he knew it. Abandon him as worthless. Leave him
alone...

 He trembled.

 Gaster eyed him, frowning a bit. Something dark moved behind his eye lights
but  Sans did not notice.
 "Shh shh it's okay... I forgive you. Yes.... I did lie. But only because
Papyrus wouldn't be useful to either of us. He's dying Sans. You wouldn't
understand why but he needs to. But that just means the two of us could stay
together. No more pain... No more fear. How does that sound?" Gaster spoke
softly, still soothingly and he hugged Sans tighter, his voice dropping to a
seductive tone as he repeated his proposition.

 Sans hesitantly raised his flickering eye lights to gaze a little fearfully up
at his daddy, hardly believing that he was not being punished and he still
trembled even as he melted into his father, his gaze turning into tentative
hope tinged with slight adoration, his face slightly flushed. He'd always had
something of a crush on his daddy. He dropped his eyes shyly, listening
silently to his daddy, the words taking too long to sink in.

 His brother? Dying? Because Gaster wanted him to? Or because he had made a
mistake? Was it because it had been 20 years? Was it Sans’ fault? Sans could
not find the strength to ask such questions but he felt as though the words had
hit him straight in the soul and it was hard to breathe, it hurt so much he
could not even move, could barely think. He just stared blankly at the wall,
starting to hyperventilate until he felt a pressure along his spine, his father
running firm fingers down from the back of his neck to his coccyx, and he could
not help the small moan that he gasped as he arched into his father’s touch.

 No...Gaster had said 'needs to'...Gaster had planned for Papyrus to die;
wanted him to die. Sans would lose Papyrus, his baby brother...just when they
had finally shared their love...Papyrus had even killed Grillby for him...his
mind was whirling. Father wanted Sans to himself, he did not want to share,
that must be why he was killing Papyrus. Did that mean he actually cared about
Sans? Wanted him? Loved him?

 "daddy...if...if someone had...hurt me..." he asked shyly, his voice barely
above a whisper and his fingers curled into Gaster's shirt.

 Gaster impatiently looked down at his son. "What do you mean? I know you can
defend yourself? You have my powers Sans..." He looked interested nonetheless.
He wanted to know what his son had been doing.

 Sans looked up at his father in confusion, his eye lights flickering. "what?
you....and Papy....always told me...that I was weak, worthless...i only have 1
hp...the...the" he looked up at his father, eye sockets widening with horror
and his breath hitched.
"I only gave you 1 hp because you were too powerful. But now you're older, I
can trust you more.... I could heal you, make you stronger..." Gaster started,
sounded thoughtful.
 Sans dropped his eyes and he tried to crawl away, shivering with self disgust
and terror, sweat beading his brow as he hyperventilated. "they...papy killed
grillby for...touching me....raping" he ducked his head and gagged. "-me...and
the dogs...." he suddenly had the revelation that his father probably did not
actually really love him, that he was just using him for some reason, that he
had not realized Sans weakness, that now he would be disgusted and leave
him...or kill him...he gave a broken sob and he felt his soul twinge with
another crack.

 Gaster growled softly and reached forward to grab Sans by his hips, tugging
him firmly back into his lap as he held him close. "You're with me now. Trust
me.... No one can get to you." Gaster growled and Sans shivered and allowed his
father to hold him, clinging to his daddy with desperation. He just wanted his
head to stop hurting, didn't want to be alone anymore.

 "da-daddy..." he murmured as he curled back into his father’s chest. He sighed
tiredly. “daddy? you....love me? right daddy?"

 "Of course I do.... Why wouldn't I? If I didn't love you why would I have
shown you so much attention earlier?" He kissed him tenderly. "Why would such
an idea get into your head Sans? You’re my first baby boy."

 Sans made a small mewl in response to his daddy's affection, his hips rocking
once before he realized what he was doing. He flushed bright red and ducked his
head, embarrassed by how needy he was.

 Gaster chuckled darkly, stroking a firm hand down Sans’ spine again. "You're
very desperate Sans. I can't reward you if you hadn't done anything.... Now if
you want to work for it then maybe I'll treat you." Gaster all but purred as he
shifted Sans on his lap.

 Sans squeaked and covered his face with his hands and pressed his femurs
together. His father’s voice just went right through him, made him feel so hot
and needy.

 "i'm sorry daddy...i don't mean to be...just been so easily...riled lately..."
he apologized meekly before peeking up at his daddy shyly, feeling sorely
tempted.

 He kissed his son again. "It's nothing to be sorry about.... I am more than
happy to fuck you Sans. You feel so good around daddy’s cock, so hot and tight.
I just want you to earn it. Work for me. If you help speed up my experiments
I'll have more time to show you affection…” Gaster promised with a deep voice,
dripping with lust.

 Sans breath hitched and his hips gave a second frantic buck and he hid his
face again. His magic was beginning to build in his pelvis again and he was
starting to feel warm and his bones felt itchy. He made a low moan in the back
of his throat and looked up at his daddy coyly.

 "ok daddy..." he agreed with a soft pant. Then he blinked and looked confused.
"but...you don't want my help with papy? must he die?"

 "He has to Sans.... It's a part of the plan darling." Gaster explained
reasonably, taking one of Sans’ hands in his and kissing the phalanges lightly,
then worked his way up until he kissed his cheek. "I don't want you touching
your brother.... But you can help me with the other phases of my plan" And then
he pressed his teeth against Sans, deepening the kiss the moment Sans
responded.

 Sans mind whirled, he felt hazy, confused, but he leaned into his daddy,
nuzzled him, opening his mouth eagerly to his father’s tongue with a moan even
while he tried to reconcile his emotions with his thoughts with his soul.

 Just 3 days ago he had been still having nightmares of his father, had been
certain that his brother had hated him, had been all alone.

 Then he'd found out that Papyrus HAD loved him, like Sans had loved him for
years.

 And Papyrus had been sweet and attentive and protective and...

 But daddy loved him too, and he'd loved daddy even before Papyrus had been
born and now daddy said Papyrus had to die...

 Sans didn't realize that he was clutching his chest, breathing shallowly in
pain, his eye lights flickering weakly.

 He didn't know what to do...he wanted to be a good boy for daddy, but he and
Papy were supposed to be together forever...

 Together...

 "daddy...when...he is about to die can I have his soul?" Sans asked slowly as
he calmed down with an abrupt suddenness.

 If he absorbed Papy's soul....they would always be together

 "No! And don't ever ask that again!" Gaster snarled, his eye lights flashing
red-violet in fury. Sans flinched at his father's anger, shrinking back in on
himself and staring up at his father blankly, his horror causing his eye lights
to blink out.
"The reason why I'm going to kill him is so I can absorb his new modified soul
and become a god Sans! I will be the most powerful monster in all of the
underground! Every single time line! I have figured it all out Sans, all of my
years of study. And you will rule with me, don't think I would leave you
out..." He kissed his son hard, hungry, as if trying to devour him, his tongue
thrusting down Sans throat as he shifted Sans to straddle his hips and began to
rut into his son with a violent intensity.

 Even as he reeled in terror, mind frozen in shock, he submitted to his
father’s lust, magic forming a dripping pussy at the base of his pelvis that
had his father growling possessively into Sans’ mouth as he rocked his own
arousal into Sans’. Sans let the words run circles through his mind, trying to
understand, but he didn't, it was if his father was speaking wingdings....he
shuddered slightly, and then with a sudden snap the words penetrated the fog of
his mind and with a broken sob he pulled away, and with a desperate whine he
shortcut the the corner of the room, staring at his father with a heartbroken
look, huddled into a ball, tears pouring down his cheek as he shook like a
leaf, pushing himself into the corner.

 "why would you..." he gasped, having trouble getting the words out through his
terror and grief. "why would you lie like that daddy? you'll just...use me
and...then kill me like papy..." he whispered. He felt ill, his father just
wanted power, that was why he’d made Papyrus, and he was obviously just going
to use Sans for the same purpose. He never loved Sans. He never would. Sans was
just a toy...
He sobbed again as something seemed to snap in his soul and he stared blankly
ahead. "I...will do whatever you want daddy...you don't have to pretend to love
me or want me..." he whispered brokenly.

 Gaster walked toward him confidently "Oh but I want you anyway..."Gaster
purred, seemingly not caring that Sans was having a panic attack. He knelt down
in front of Sans; lifted his chin and kissed him. "You're such a good obedient
boy.... I'll might even give you the honor of watching me murder your little
brother. We can rule the universes together Sans... You do want to be with me
don't you?" Gaster asked with a low, seductive purr.

 Sans sobbed and tried to flinch away. "I don't believe you..." he whispered,
scared.

 "There's only one way to find out isn't there Sans?"

 Sans shivered and looked up at his father, desperate for his words to be true,
but terrified as he remembered all the experiments from his childhood. But it
seemed no matter what he did he would loose his brother, so his father was all
he had left. With a small gasp he held out his arms.

 Gaster pulled him close into a hug, nuzzling his throat for a moment before
biting lightly, causing Sans to moan. "Shall we go kill your brother then? He's
ready.... I've injected him with enough determination and dark matter that he
is almost corrupt and absorbing his soul will give me the equivalent of 50
human souls!"

 Sans wrapped his arms around his daddy's neck and his legs around his hips,
hiding his face against his daddy's neck, nodding even as he felt his sins
crawl down his back. He was betraying his brother. But...he slowly realized, a
little giddily, his brother would live in his daddy, he would still have both!
He hugged Gaster tighter.

 Gaster walked Sans to the lab. Papyrus was in a special cage, he looked
absolutely terrible. He saw sans and started banging on the walls calling his
brother for help. "SANS! SANS HELP ME!!!" He was crying.

 Gaster chuckled and looked at sans. "You know.... I think it would be amusing
if you killed him. Him begging makes me laugh." Gaster handed Sans a knife.

 Sans looked up at his father with blanked eye lights, horrified, and he slowly
looked over to see his brother, and then back to his father. He looked down to
his hand, seeing the hand and the knife as if they did not belong to him.

 His mind raced. He could kill Papyrus to please his father. He could shortcut
into the cage (try to) and grab his brother and escape (try to)....but the cage
would probably block that attempt, then daddy would kill them both. If they did
escape....determination would kill Papyrus anyways, and they would not be able
to avoid their father's reach long anyways...so what choice did he have?

 "do...i have too?" he sobbed in a whisper.

 "Yes sans." He grinned, his eyes full of sadism. "Go on... Kill your baby
brother.... Make daddy proud."

 Papyrus looked at him in fear which only made things worse. He was begging.
"SANS! SANS PLEASE! DONT DO THIS! HE DOESN'T CARE ABOUT YOU! I LOVE YOU SANS!
PLEASE!!"

 Sans looked at his brother sorrowfully and then back at his father. He knew
his father didn't love him, but Papy was dying, there was no way he could
escape with his brother, keep him alive. But...maybe one day he could get
revenge. As long as he got his father to believe sans completely under his
control...but he would never be able to forgive himself for this...he closed
his eyes, feeling exhaustion overtake him.

 "okay daddy...i love you daddy..." he said softly, kissing Gaster gently on
the teeth before taking a shortcut into the cage. He gave his brother a broken
look. "i'm sorry papy....i love you...don't worry....i'll be right behind
you..." Sans promised with a sob. He gave his brother a loving kiss, stabbing
the knife into his brother's vulnerable soul before reversing it to stab his
own...
***** Consequences will never be the same *****
Papyrus looked at his older brother in disbelieving horror,  his eye sockets
empty hopeless voids and he shuddered in despair that Sans knew echoed his own,
could he do this? He had to…
 "But.... You promised...." Papyrus whimpered; his last words before he
completely turned to dust. Sans froze for just a moment, the slowly dawning
horror of what he’d just done, of how he’d just murdered his little brother,
his baby brother… came crashing over him like a wave, his hand trembled as he
began to turn the knife on himself.
Gaster teleported inside the cage in that moment; laughing loudly as he
snatched the knife away just after Papyrus began to dissolve into dust and
before Sans could act to finish his own life. He grabbed hold of Papyrus' soul
eagerly, his face a mixture of lust and unholy glee that had Sans trembling,
eye sockets wide and his breath trembling.

 "Oh no you don't. I'm not letting you escape from me that easily, my love...My
darling Prince." Gaster growled.
Gaster cackled as he started to absorb Papyrus' soul, turning into a god like
figure that still resembled himself. "My prince.... No... King...." He scooped
up his son into his arms, cradling him possessively against his chest as he
kissed him hard and deep on the mouth. "I always knew you loved me more than
your brother." He cooed with satisfaction as he held Sans possessively, almost
tight enough to crack Sans’ ribs.
Sans sobbed with terror but threw his arms around his father and met the kiss
with a mixture of sorrow, anger, lust, and self-hatred. He was despicable, but
he wanted his daddy to make it all better.

 "daddy...don't leave me..." he sobbed. Gaster was all he had left now. He
killed his brother...he deserved to die, but if daddy did not want him to
die...he would just make his daddy his world.

 "I would never Sans.... You killed your brother just to be with me. You've
earned a reward Sans~" Gaster purred, his voice deep and husky with promise,
his eyes hooded as he gazed hungrily at his son.

 Sans looked up at his daddy breathlessly, flushing and looking heated from the
tone of his father’s voice, feeling his magic pooling in his pelvis already.
He was such a filthy slut.

 "...what kind of reward daddy?" He asked shyly, although he wondered  inwardly
if anything was worth the fratricide he'd committed. Willingly.
He felt ill, his sins crawling up his back, his soul throbbed painfully and he
gasped with as a sharp crack let him know he had damaged his soul with his
actions; it was all that he deserved. He leaned into his father, trying not to
whimper, trying not to cry. Gaster placed a pair of fingers under his chin and
all but forced his head up.

 "Whatever you want my king..." Gaster promised while he kissed him lovingly.
"And then after we will take what is ours."

 Sans blinked up at his father, all his fears and sins fleeing his lust addled
mind and he stared at his father, flushing faintly at the affectionate kiss.
"king, daddy? but...aren't you...going to be king? wouldn't i be your queen?"
he flushed redder at the statement, eyes drifting the side. "especially
since..." his eyes widened and he clapped his hands over his mouth as his whole
face flushed a bright crimson. He hoped his father did not ask what he was
about to say, it was so embarrassing. He did not know how his father would
react if Sans were to admit that he wanted his daddy to impregnate him, wanted
to be swollen with his seed….he pressed his femurs together, trying not to pant
even though just the thought had him feel wet and needy.
Gaster chuckled, sounding deeply amused. "If you want... I'll be a god either
way. King is only a step down. But I want you to be whatever you're comfortable
with." He kept kissing down his neck bones, lightly biting the vertebrae and
causing Sans to moan.

 Sans flushed a brighter red, fervently grateful that his father had not asked
him to finish his statement. He continued to look away shyly although he
shifted his head to give his father access to his neck and tried not to pant
too audibly.

 "i...am not very good at being in charge..." he muttered in shame, because
that was what a king was right? The one in charge? Who...did all the ruling and
making orders and shit? He was really much too lazy for that to be remotely
palatable for him.
"You won't have to be in charge, you're only purpose is to be obedient for me.”
Gaster informed him, slightly impatiently. Then his expression softened to a
possessive leer. “You can do that can't you…?" He asked with a purr.
Sans stared up at his daddy with half-lidded eye sockets and nodded slowly.

 Gaster looked pleased with his response and snapped his fingers, dark magic
danced beneath them summoning a bed. He pushed Sans down and slowly started to
pull off his t-shirt while licking his teeth hungrily, his violet eyes hazy
with lust.
Sans squeaked slightly in surprise, but laid back willingly enough, looking
shyly up at his father while allowing himself to be undressed. His daddy was
going to make him feel good again, he began to tremble eagerly, his face
flushing red and eye lights going hazy with lust as he submitted to his father.


 "daddy….” he moaned, lifting his hips as his father took off his pants in a
teasingly slow manner, his fingertips brushing roughly over his pelvis.
“daddy....please…”

 The tentacles coiled around him once more, starting at his ankles and winding
up his legs slowly, squeezing as they went until they got to midway up his
femurs; another set wrapped gently around his wrists, almost lovingly. Sans
shifted his attention to watch the tentacles curiously, enjoying the feeling of
them stroking his bones, the pressure, the feeling of helplessness.
"Such a good boy sans.... Daddy loves you so much.. I want you to marry me
Sans.."

 Sans’ spun his head back to face his daddy so fast he nearly snapped his own
neck, his eye lights diluted so much they nearly took up his entire eye sockets
and his flush extended down to the middle of his rib cage.

 "D-daddy?" Sans asked breathlessly as if he could not believe it, his eye
lights shrunken to pin pricks. Not that he was against the idea, in fact, the
prospect had him squirming.
"Be my lover, with me forever. You have proven yourself. I'll give you the life
you deserve... Pleasure you everyday, love you everyday. My darling son..."
Gaster promised huskily as he loomed over him, eye lights almost glowing as he
kissed him once more

 Sans eye lights flickered into heart shapes for the briefest of moments, and
although deep inside he knew he was being manipulated, he reached for the
promised affection eagerly, metaphorically and literally, reaching his arms out
to his father, and squirming eagerly beneath him, moaning wantonly into the
kiss.
"is that a yes then..? My queen..?" Gaster grinned happily, his eye lights
returned the heart shapes. "The timelines will be ours tonight, there's no time
to lose. Let's get married tomorrow. We can make it as public or private as you
want. I want the best for my bride."

 When his father's eye lights became hearts is surprised him, that was not
usually something that could be easily faked, and it may just be his father's
lust, but it did warm his soul slightly, as well as inflamed his lust and he
wrapped his legs around his daddy's hips and bucked into him with a whine.

 "daddy! take me! please!" he demanded, he needed to be filled; now.
"First... Say you want to marry me. Then I will take you." Gaster teased as he
hungrily lapped at his neck and ribs, the tentacles were starting to pull his
femurs apart, a pair wrapping around his spine and coiling around his lower
ribs, stroking and rubbing and squeezing, Sans writhed and mewled beneath his
father, eye lights rolling back.

 "daddy~" he whined with a pant as he tilted his head back. "yes, daddy!
i'll....marry you..." he whispered shyly, but with absolute devotion and
sincerity in his voice. “i want to belong to you daddy…”

 Gaster’s eye lights were hearts again as he pulled out his throbbing cock and
rubbed it against Sans' pelvis. "My bride... My beautiful son...." he purred
possessively.
Sans gave a stifled moan, stuffing his fingers in his mouth as he rocked his
hips up against his father's; arching his spine and curling his toes. His pussy
had already formed, wet and dripping and he rubbed himself shamelessly against
his father, wetting his length with his juices.
"Ahh ahh ahh let me help you with that..." A tentacle finished winding it’s way
up his spine -Sans writhing and moaning at the sensation, his eye lights
dilated and hazy- before sliding up the side of his face gently before shoving
its way deep down his throat, it was wide enough that he jaw barely fit around
it. It tasted exactly like Gaster's cock. Sans whined low in his throat as the
tentacle entered his mouth, his tongue and throat forming the moment the
tentacle passed his teeth, and although the tentacle was almost too big,
pressing his jaws as wide as the joint allowed, he almost purred with pleasure
at the taste and weight of it on his tongue. Daddy tasted so good.

 He swallowed as best he could, trying not to gag although tears did spring to
the corners of his eye sockets. The weight of the tentacle on his tongue, the
way it stretched his throat the the burning point, it was so good...

 Gaster made a low growl deep in his throat, his teeth clenched in a snarl and
he suddenly thrusted himself inside of his son, hilting immediately before
pulling almost all the way out and he started bucking his hips back and forth,
making love to his sweet future wife, panting lightly, and to Sans’ fevered
mind, it did seem that his father was being more vocal this time, more into it
then the first time he’d fucked Sans. His eyes rolled back and he squealed
around the tentacle when his father entered him, and his thoughts began to go
hazy, it felt so good, daddy was so big!

 He gasped as best he could, trying to buck back, to meet his daddy's thrusts.
"Such a  sweet  boy Sans...so tight and hot for daddy...This isn't too much for
you is it sweetheart?" Gaster cooed softly, sounding almost concerned.

 Sans made a small whine in the back of his throat around the tentacle as he
met his daddy's thrust the best he could, shaking his head frantically; he
wanted more!

 Gaster smirked as he rammed his giant cock deep inside of his oldest son. He
pulled back and rammed hard again and again, making Sans scream around the
tentacle stuffed down his throat, the sound coming out as little more than a
desperate gurgle as he threw his head back and arched his spine before wrapping
his legs around his daddy's hips to pull him deeper.

Gaster grabbed his cheek and yanked him closer. "You are quite the slut... I
absolutely love it.." He licked his cheek again. “Daddy's little slut..."

 Sans whined slightly when his daddy started talking dirty and flushed red, but
did not even try to deny it. He sucked harder on the tentacle and rolled his
hips.

 "I love you so much.... My precious bride..." He started to thrust faster,
getting closer to climaxing and he pushed himself up until he was on his knees,
his hands gripping Sans’ pelvis almost to the point of pain and his new angle
allowed him to penetrate deeper and he found Sans’ G-spot which had Sans
squealing breathlessly around the tentacle, squirming frantically, not sure if
he was trying to get away or get closer as he threw his hands to the side to
grip at the blanket beneath him.

 Sans tried to call out but the tentacle muffled all his cries as he too felt
his climax building, a tightening ramping pressure within his magic that was
making his vision go fuzzy around the edges. He just gave his father a look of
adoration as he chased his orgasm.
Gaster was coming close, he was panting. "S-scream daddy's name won't you
Sansy?" He was getting close, his magic built up about to burst

 Sans tried to comply but all that came out was a gurgled moan, so giving his
dad as arch a look as he could manage (while still looking completely
debauched) he tugged slightly with his hands at the tentacle in his mouth.

 But the garbled noise seemed to be good enough for Gaster; he threw his head
back with a low groan as he came deep inside of Sans, filling him deep,
refusing to leave him. Sans eyes rolled back and he made a high keening whine
around the tentacle as he felt his father's cum fill him, it felt so good and
it sent him over the edge and he came, his walls convulsing around his father,
milking him dry. Even after his vagina oozed with cum his daddy continued
thrusting until his magic faded completely several minutes later while Sans
whined and writhed, crying from overstimulation.
As soon as his daddy finally pulled out he would reach for him, a look of
satiation on his face.

 "Daddy..." he panted, exhausted, but satiated.

 "Yes son...?" Gaster took his hand and held it gently

 Sans looked shyly up at his daddy, face flushing as he leaned forward to
nuzzle his daddy's hand.

 "...cuddle?"

 He smiled down at his son. "Of course... Anything for the love of my life." He
snuggled next to Sans and kissed him tenderly, his eye lights were shaped like
hearts

 Sans flushed bright red, his eye lights also hearts, and his soul began to
flutter.

 "really, daddy?" he whispered coyly as he rubbed himself against his daddy's
chest, snuggling into his arms.

 "Of course..." He pulled sans close and sighed, sounding happy, or at least
satisfied. He held Sans close and they laid in comfortable silence for several
minutes until Sans was half-asleep.
“Sans... You don't miss your brother do you?" Gaster asked slowly, his voice
low and tight; he sounded angry,  possessive.

 The possessive tone in his daddy's voice had Sans feeling warm and he felt a
tinge of pleasure of having that emotion be displayed by his daddy, but he also
felt sad by the question and he looked away as he thought about how best to
answer.

 "of course i do..." he sighed and turned his attention back to Gaster, staring
him straight in the eye as he continued. "...i raised him....i was...i always
loved him, and...you reinforced that in the early days so i just never....got
over it. and...well...you saw,,.what we did together...?" He trailed off,
feeling sad, embarrassed, guilty, and he closed his eyes with a sigh. "i became
rather co-dependent on him over the years, it was the only way to survive, i
would have been killed if he had not staked his claim on me, and intimidated
everyone away....but..." he opened his eyes again "you....absorbed his soul
so...really...he's...still there?" he looked a little confused. "and i..it was
only just an...hour ago that i..."  he could not say it...he closed his eyes
feeling guilty.
Gaster only frowned. "You don't have to pretend Sans. I know you've always
loved me more, you've even proven it to me." He was definitely sounding
jealous, his voice deep and tight. Jealous of his own son now, even though he
was dead now, no longer a rival. "Don't think of me as your brother. I am only
me... And I'm here to love you better than he ever will." He kissed Sans
tenderly. "We're getting married first thing tomorrow morning, I don't care
what you say, then after that I will give you the fucking of a lifetime.”
Sans eyes snapped open to stare up at his daddy with shock, a small flush
coloring his cheeks. Did Gaster sound, jealous? If he really was just a means
to an end, would his father be so...possessive and jealous? Sans did not think
so, and he began to tentatively hope that maybe, just maybe, the heart shapes
in his daddy’s eye lights were not illusions, were not lies. He felt a twinge
of guilt about Papyrus, but he was also so happy that his daddy wanted him so
badly.
 “And take this disgusting thing off!" He ripped Sans' collar off, the one
Papyrus gave him, and destroyed it in one touch. "You're mine now."
“i can’t wait for the honeymoon, daddy…” he teased lightly, not complaining at
all about the ‘I don’t care what you say’ line, although that had made him feel
slightly cautious with showing any attitude or resistance. But he had always
liked being dominated, so having his daddy control him was more of a turn on
than anything. He flinched a little when his collar was ripped off, but did not
complain. Instead he leaned up to return the kiss.
Gaster hungrily deepened the kiss. "Now go get cleaned up and come to bed won't
you? We have a long beautiful day tomorrow..." He kissed his son hard once more
before dismissing him. "I'll be late to bed tonight. I'm going to start my
empire, the perfect setting to our marriage."

 Sans returned the kiss with a matching hunger, mewling softly with
disappointment when his father pulled away. He felt a little dazed but was
starting to feel coherent again, but he could not help but peek up at Gaster
with cautious delight.

 "you actually want me to share your bed? every night?" He tried not to sound
so hopeful for a positive answer. He flushed and dropped his eyes. "i would
have thought you would prefer to...have privacy...or...get tired of me
or...well I get nightmares and...and would not want to...disrupt your sleep
daddy..." he realized he was babbling and with a small whispered apology he
slipped out of bed to clean himself up.
Gaster gently grabbed his shoulder before he could leave, pulling Sans into his
arms and nuzzling his neck possessively. "Of course I do... Do you not trust me
when I say I love you? I can take away your nightmares... It won't be hard." He
kissed him once more before letting him go

 Sans looked up at his father with a shy smile as he calmed down from his
anxiety attack. "i trust you daddy..." he said softly. He acknowledged to
himself that he probably shouldn't trust Gaster, but he did.

 "Good boy.... Now hurry up and get to rest. Daddy has a lot of work tonight
and then in the morning we are to be married. And then after... Daddy is going
to fuck your brains out like never before.." His voice purred

 Sans' eyes glazed over and his breath hitched at the promise in his daddy's
voice and he made a small mewl in the back of his throat as he hurried to
comply. He found a wash-stand in the corner of the room and gave himself a
quick wash before trying to decide if he should crawl into bed naked or pull on
his dirty clothes. He decided to just pull on his t-shirt and crawled into bed,
exhaustion weighing on his bones as he started to get comfortable.

 "night daddy...have fun taking over the world..." he murmured as he drifted
off to sleep.
***** Wedding Day *****
Sans woke up that morning to the feeling of a large throbbing cock shoved deep
inside of his vagina. His father had taken him as he was asleep, and from the
feeling in his pelvis his father had been at it for quite awhile, and Sans
could tell from the residual tingling and how wet the bed was beneath him that
he had cum at least once or twice while his father plowed him. Sans had been
panting and rocking his hips even in his sleep, and he slowly blinked his eyes
open with a low moan; he looked up to see his father staring intently at his
face, heart shaped eye lights were fixated on him. Disembodied hands were
caressing the half-asleep skeleton, stroking along his pelvis and his ribs, one
hand wrapped around his spine and stroking him firmly in time with the
thrusting of his hips. The hands on his ribs were pulling, almost to the point
of pain, but it sent a burning sensation down Sans’ spine and straight to his
pussy, and he arched his spine with a squeal as he blinked his eyes open in
shock before cooing with pleasure at the feeling of being stretched so full
that it burned.
"daddy!" Sans gasped as his eye lights dilated and he reached out to wrap his
arms around his daddy's shoulders as he rocked his hips to meet Gaster's
thrusts.
"Good morning Sans... I'm sorry I couldn't help myself" Gaster moaned as he
leaned forward and lapped at his teeth hungrily when he saw that he was awake.
Sans conjured his tongue and lapped his father's tongue a couple times like a
kitten before opening his mouth for his father to take.
Gaster shoved his tongue deep inside of his mouth, thrusting harder.
Unfortunately he was already close to cumming, he's been going at Sans for a
while now.

Sans sucked on his daddy's tongue with a happy moan, his eye lights becoming
hearts as he was pounded into; his daddy was so big, it felt so good...his
daddy's driving pace was pushing him closer to his own release and he began to
buck his hips even faster, trying to drive his daddy's thrusts even deeper.

 “da-daddy~” he squealed happily, throwing his head back and writhing
underneath his daddy wantonly, not in the least upset about being taken while
asleep. “uhnnn...so big daddy!” he gasped and threw his head to the side as
Gaster hilted roughly, pausing before pulling out slowly, teasingly.
“da-da…ddy~” he whined, needing more. “please!”

 “Oh, Sansy...does my little boy like waking up to his daddy’s big cock?”
Gaster panted, leering at his son as he teased him.
“da~....daddy, yes, please, harder, please daddy!” Sans whined desperately.
“As you wish, daddy loves wrecking his little boy…his little cunt is so tight
and hot~” Gaster purred as he resumed his earlier pace, pounding into his son
so quickly that Sans could not meet the thrusts, could barely make a coherent
thought, all he could do was pant and moan as he was used.
“Even after you’ve cum so much you’re still so tight around me, oh...I made you
so perfect for me!” Gaster growled as he leaned forward over Sans, pressing his
son harshly into the bed beneath him as he angled Sans’ hips up towards his
chest, thrusting deeper and hitting Sans’ back wall every time he hilted,
making Sans wail and squirm.
Gaster came inside of his son once more, eye lights flickering into purple
hearts as he made a low moan, panting ever so slightly from exertion.
Sans made a low gasp when he felt his father fill him, bucking his hips
frantically while he chased his own climax, finally coming with a small cry
before laying back and blinking sleepily up at his father, his cheeks flushed
red.
The lay like that for a few minutes and then Gaster slowly drew out of his son
with small groan that Sans echoed before he lay down besides his son, wrapping
one arm lightly around him and just staring at him for another couple minutes.
"My child..... It's our wedding today.... In a few hours I'll be able to call
you my wife...." Gaster broke the silence with a pleased grin before he leaned
down to kiss his son hard and possessively.

"i can't wait, daddy...it will be wonderful..." he looked to the side
thoughtfully as he considered something he ought to bring up. His bones were
feeling very warm, and he had been so easily riled the last few days, almost
insatiable. He glanced back up at Gaster shyly. "i...think i might be going
into heat..." he whispered.

Gaster chuckled, but he looked not only pleased, he looked delighted, and
hungry. "Do you think you can control yourself until after our wedding sans?"
He asked in a low teasing voice, even as he stroked a hand lazily down Sans’s
sternum.

 Sans flushed, pressing his femurs together as he nodded. "yes daddy..." he
promised, but in reality he was not sure. He was so hot...
But Sans realized he was behaving thoughtlessly so looked up at his daddy with
a sweet smile, his golden tooth glinting in the low light. "so...was your night
successful, daddy?"

"Of course it was... Our empire is growing Sans... And I have gathered quite
the audience for today." Gaster boasted.

Sans beamed up at his daddy, he was so amazing and powerful; but the thought of
such a large audience had him ducking his head and flushing, suddenly very
nervous.

"are...you sure you....want me daddy? i'm...so...damaged..." he whispered,
running one hand over the large crack above his left eye socket, and thinking
of all the cracks in his bones...he was hideous.

"Are you comfortable? I can change anything to your comfort. Of course I want
you... If I didn't I wouldn't be marrying you. I built you to be my future wife
and now here you are... Sans you were to marry me before you were created. Your
brother was made in case something happened to you. If you survived then your
brother was to be executed." Gaster purred as he leaned down into his small
son, pressing a femur into Sans sensitive pelvis, still soaked with their
release.

Sans blinked once and slowly turned to look up at his daddy, eyes wide, and a
blush slowly covered his face down to mid-ribs and he rocked absently into his
father, spreading his own femurs lewdly.

"...you created me to be your wife?" he breathed, hardly able to believe it.
His daddy had made him for this purpose...he shifted, closing his femurs
suddenly around his father’s rutting against him with a gasp and flushing a
darker shade as he tried to repress his lust, although his bones all felt warm
and overly sensitive.

 But a thought intruded on his mind, and he wondered...all the experiments, the
tortures...what point had those been for?
"Of course I did..." Gaster cooed lovingly.  "I loved you since before you were
born..."

Sans looked back up at his daddy, and all thoughts of the dark, cold, lonely
nights chained to an examination table fled and he all but threw himself into
his daddy's arm, still rutting mindlessly against his father’s broad femur,
sliding his still soaked pelvis against him.

"i just want to look beautiful for you daddy!" he gasped.

Gaster kissed him tenderly. "And you will... I picked out a beautiful dress for
you... Are you ready to get dressed for our wedding my love?"

 Sans arched his spine and tightened his arms around his daddy and returned the
kiss, and he gave a small moan as he felt heat pool in his pelvis as his magic
began to form, but he pulled back, trying to rein in his lust and nodded. "i'm
ready daddy..."
Gaster summoned a beautiful dress that was black and white. "For you... The one
I love the most...." Gaster cooed, and Sans did not see the calculating look in
his father’s eye lights.
Sans stared at the dress a little breathlessly, it was beautiful. He had never
given much thought to wearing dresses before, wearing feminine crap like that
would have just made him a bigger target, but he had to admit that it was very
pretty, and he was itching to try it on, to be praised...to make his daddy hard
for him. He squirmed a bit where he sat, his mind already thinking to the
honeymoon before he reined it in with a sharp mental jerk and he turned to look
up at his father with a serious and determined expression. "what do i need to
do for the ceremony?"
"This will be different since the ceremony will just be us two but.... Just let
me do all of the talking and then say 'I do' when the time is right." Gaster
informed him a little impatiently.
Sans raised an eyebrow and shrugged lazily, although he was feeling very
excited. "okay daddy." he got up and stretched, allowing his joints to pop and
settle, he glanced over his shoulder and saw his father eyeing his form
hungrily, and Sans felt just so slightly smug.
"Now go get changed... I'll get changed as well. I want to look handsome for
you of course." Gaster informed him, his voice slightly husky.

 Sans glanced shyly up at his father, blushing slightly as he took the dress,
focusing his attention on the material, admiring the workmanship (and also
figuring out how to put it on). He went to the wash basin and cleaned himself
thoroughly, scrubbing his bones until they glowed. He even put some effort into
forcing his magic to heal some of the deeper cracks to make his bones a little
smoother, also (considering his father liked to be so rough with him) he made
his bones just a little sturdier and his ribs a bit springier.
After making certain he was absolutely spotless, Sans began to pull on the
dress, although he had to contort his spine a few times to get it laced up
properly. It reached to the floor, swishing around his feet, light and airy. It
was a really fine gown.
He frowned at the floor as he adjusted the skirt, wondering why he was allowing
his father so much control over him...it’s not like he had anything else to
live for with papy gone, (at his hands, he’d killed him, he was the worst), and
the sex was amazing, but he was honestly wanting to please his father so much
it hurt...even though he knew, he knew deep in the back of his soul, that his
father was just...playing him. And that hurt more than he thought it would.  
He really did want to look beautiful for his father, he wanted his father to be
proud of him (actually pleased, and not just claiming to be pleased to
manipulate Sans), he wanted his father to take one look at him and have to
restrain himself from tearing the dress off of him...he wanted to drive his
daddy insane with lust. He glanced thoughtfully at the bodice and adjusted it a
bit until it showed a bit of clavicle and sternum. It actually flattered his
delicate figure rather well, he just wished there was a mirror…he actually took
the time to look around the room for the first time and to his satisfaction he
found a full length mirror in one corner of the room.
He practically skipped over to the mirror and gave himself a critical once
over. The bodice and waist were a little loose, and after careful
consideration, using some of the extra magic practically dripping off his over
sensitive bones, he formed an ectobody from his knees up to his clavicles, with
just enough of a bosom to press into the front of the dress, and he admired the
effect, pleased.
He gave a small twirl in front of the mirror, enjoying the feeling of having a
body, enjoying the feeling of the dress swishing airily around his ankles.
Gaster stepped into view as he finished spinning, his eye lights twinkled into
hearts, his face flushing purple and he growled hungrily as he slowly
approached his son. "Sans.. You look beautiful...." He purred, his voice
sending a bolt of lust down Sans’ spine and he gave his father a coy grin.

"hello, daddy..." he purred in return.

 Gaster was in a dark violet tailored suit, he looked quite handsome in it. He
stalked slowly towards Sans, his face slowly smoothing into a more calm
expression and he carefully kissed Sans as lovingly as he could. "Are you ready
son...?" He asked softly, and Sans could all but feel the tension roiling in
waves off his father; he was restraining himself admirably, but Sans had
finally managed to crack his control a bit it seemed.
Sans could not have been more pleased by this, he leaned up into his father
happily, a small flush on his cheeks.

"yes daddy..." he repeated, almost giddy.

He picked up the edges of the full skirt and gave a little spin, this time
deliberately putting a show on for his father, smiling coyly. "the dress is
lovely."

 Gaster’s eye sockets went half-lidded as he hummed thoughtfully.
"I'm glad you like it... It will go very well with the ring I picked out for
you. Now we must go." Gaster commented with a small pleased grin as he took
Sans’ hand and started out the door at a brisk pace.

Sans allowed his father to lead him, and took the chance to notice how well his
father filled out his suit. His bones felt very warm and lust coiled in his
pelvis. With a slightly breathless gasp and a flushed face he dropped his gaze
the the floor, picking up the edge of his skirt with his free hand so that he
would not trip and embarrass his father.

"I took note that you didn't want an audience but... I thought we should at
least have one person watching.” Gaster commented airily, turning to look down
at Sans with a loving smile. Sans looked up to see one other monster in the
room with them.

 A monster strapped to a chair. A familiar, beloved figure that Sans had never
thought he would see again, not even in his dreams.
It was Papyrus.
He was screaming with a ball gag in his mouth.
Sans mind shrieked.
Sans had been a hesitatingly a little excited about the wedding, almost looking
forward to a life as his father's queen (bedmate? Sex slave? ), hoping to have
his father’s children and maybe someday, somehow, get his father to love him.
To return his feelings even the slightest. But the moment they entered the
chamber his body locked up, his eye lights flickered out and the only reason
forward motion continued was because of his father's hold on his hand. His mind
would not accept what he was seeing, and he felt something vital fracture.

Gaster seemed to not notice how upset his son was (either of them), or else he
did not care as he chuckled and waved an arm grandly as he gestured to the
bound skeleton. "Just for our big day I took Papyrus from the past to come join
us... In a couple hours you wake him up to comfort him from a bad dream. Oh how
I loved fucking with him when he slept... Too bad he's dead now, and all
because of his older brother." Gaster explained lightly, as if he was not
literally breaking Sans’ soul.
Papyrus was desperate, screaming, tears streaming down his face, he was so
scared of his father and he did not know what was happening. He was so scared
he was shivering, and Sans had never seen his brother in that state, not ever.
Even when he had woken up to find Papyrus having a nightmare he had not seemed
so, lost, so small and frail, so...helpless. And he had done this to him, it
was his fault.
"papy..." Sans finally managed to gasp weakly before slowly turning to look up
at his daddy with haunted eyes, trembling, reproachful. He could not believe
that Gaster would do this to him; could do this to him. His father had already
made him prove his loyalty by killing him, how could he possibly make Sans face
him again? It was the worst thing his father had ever done to him, and he felt
revulsion for his father run a chilly finger down his spine, and for the first
time since he had run into his father, he felt a deep, seething hatred, coiling
in his soul and pulling apart the love.
"daddy...why would you..." he struggled to formulate a question, any question.
His mind whirled. How long had their father been taking Papyrus against his
will in his dreams? How many times? And why had he never come to Sans in his
dreams, did he even really want him? Was Papyrus his first choice for a lover?
Why torture Papyrus this way? Why torture Sans? Why?
He looked back to Papyrus with a horrified sob, but did not try to leave
Gaster's side although he suddenly felt disgusted by the feeling of his
father’s hand in his.
"Because I knew you would want your baby brother at your wedding? Was I wrong?"
Gaster asked gently, as though honestly concerned. Papyrus was screaming for
help, screaming for Sans, not knowing of what Sans would do to him in the
future. Not knowing that all he had to look forward to was pain and then death.
Not knowing that him loving Sans was the worst choice he could have ever made.
But this was the tipping point for Sans, as it had always been. Papyrus had
always been his sore spot, and his father knew that very, very well indeed.
Sans looked up at his father with a snarl, eye lights flickering back to life,
his left eye light glowing with a crimson flame and he ripped his hand from his
father's with a low growl and stood facing the taller skeleton with his hands
in tight fists on his hips as he restrained his fury the best he could. He was
actually shaking with fury, and he tried to ignore the way his father’s eyes
dropped briefly to his heaving bosom.
"you know exactly what you were doing, bringing him here. i already submitted
to you, i…-" he was about to admit to loving his father but bit that back, his
father would only use that against him. Just like he was using his guilt and
fear against him. "-why are you trying to...destroy me?" He asked, his voice
hitching with pain, the hatred began to recede as he looked up into his
father’s eye lights, it was so difficult and tiring for him to maintain.
"Destroy you? And here I thought I was being nice letting you see your brother
again. Alright. I guess if you never want to see him again... You must really
hate him." Gaster sounded disappointed and as though Sans had hurt him by
refusing his thoughtful gesture. He raised his hand about to send him away
"daddy no!" Sans lunged forward, grabbing his father's arm frantically. "please
daddy..." he tried not to cry, his father was so cruel..."please daddy...I'm
not stupid, and neither are you...you..." he stuttered to a stop and pulled his
father's hand to his face and nuzzled it. "don't hurt him daddy..."
Papyrus was hyperventilating through the ball gag, it was obvious he was in
pain. He wanted Sans to help him, why wasn't he helping him?
Gaster smiled and put his hand down. "Very well. I only want to make you happy
Sans." Gaster said lovingly.
Sans flinched slightly before peering up at his daddy, not quite able to hide
the heart broken look in his eyes before he pulled away, dropping his eyes and
shivering slightly as he wrapped his arms around his ribs and looking at his
baby brother. His soul ached with the despair that his father really thought he
was so stupid as to buy that. While blatantly trying to break his mind. His
father did not love him, he doubted his father was even capable of more than
possessiveness and lust, but Sans...Sans loved his daddy, loved him to the very
depth of his soul.
Oh, poor Papyrus...why couldn’t daddy have just left him alone, Sans felt the
weight of his sins on his back as he started to walk towards his brother,
almost against his will.
Papyrus looked at him with a pleading look on his face. The ball gag and the
ropes were hurting him badly. Sans turned his head ever so slightly, just
enough to peer carefully at his father. He just had to be sure...
Gaster just watched, a small sadistic grin on his face.
Sans whirled his face back to look at his precious brother, took a second step,
and when his father did not say anything he broke into a run while picking up
his skirt, and threw his arms around his brother's neck, trying not to sob.
"i'm so sorry papy, i love you..." he whispered softly, trying to ease his
brother's pain.
Gaster only watched in amusement.
Papyrus was confused. He tried mumbling hoping sans would take the ball gag off
Sans raised his fingers and after a moment took off the gag, stroking his
brother's cheeks lovingly with gentle phalange tips.
His bones were starting to feel warmer, even with his emotional distress.
Papyrus coughed then looked up at his brother. "Can we go home yet...?" He
asked trembling, terrified of what their father had in store for them. "I
just... Want to wake up... And you to tell me everything is going to be
okay...."
Sans climbed into his brother's lap, wrapping his arms around his shoulders
lovingly. "for you this is just a bad dream, papy. you'll wake up soon, with
me, but...the me here...can't wake up..." Sans tried to coo soothingly, his
voice broke slightly, but he thought he had managed to sound comforting.
Papyrus nervously kissed his brother assuring him everything would be okay.
Gaster’s face flushed with sudden rage, his teeth twisted in a snarl and it was
obvious that he felt a pang of jealousy as stormed toward the other two. He
back handed Papyrus violently until he was in tears "Don't you fucking touch
him you son of a bitch!!" Gaster all but screamed, eye lights burning with a
violet flame.
Papyrus yelped in pain.
Sans blinked and then scowled as he leaned forward to pull Papyrus protectively
to his ecto bosom and gave his father a growl. "why do you care?" he snarled,
surprised by his father’s mood swing, and angry that he’d hurt Papyrus.
Gaster growled, still looking furious, but now actually looking a little
frantic in his anger, his eye sockets wide, his eye lights glowing pin pricks.
"Because you're mine! You’ll always be mine, mine and no one else's! MINE! Now
let's hurry up with the ceremony!"
"What ceremony...?" Papyrus asked with tears in his eyes, shivering with terror
at his father, eye lights darting frantically between him and his brother,
confused and scared and in pain.
Gaster forcefully shoved the ball gag in his mouth. "One more word out of you
and I'll be shoving something much bigger in your mouth." Papyrus cowered in
fear. He knew what he meant. He just wanted to wake up... He hated his
nightmares.
Sans scowled and with a look of pure defiance kissed Papyrus' cheek before
climbing off his lap (reluctantly, he was starting to feel hotter, he wanted
more physical contact). He stared up at Gaster with a small growl. "if I'm not
allowed to touch anyone else neither are you!" He snarled with more
possessiveness than he had meant to display. After the words left his mouth he
clapped panicked hands over his mouth.
Gaster growled and grabbed Sans almost desperately, pulling Sans flush against
him, lifting him enough that he could grind their pelvises together. "You are
mine and you will only be mine! That's why I killed your brother! Really I
could have done that experiment on anyone but I chose your brother just to take
him from you! And with our marriage you'll be mine forever!" He dipped him and
kissed him deeply, hungrily.
Sans gasped softly when his father grabbed him, face flushing a bright red and
he did not fight the embrace although his eyes started to slide over to Papyrus
before he was suddenly leaned backward, his squeak was muffled by Gaster she
mouth, and turned into a hesitant moan. His ectobody included a vagina, but now
he was starting to feel wet, and some of his arousal began to drip down his
thighs.
"Wait what...?" Papyrus was starting to panic at what his father said.
Marriage? Killing? And Sans didn't care?? He was kissing him back. Thoughts
swirled through his head until he just started screaming through the gag.
Sans was clutching his fingers in the front of Gaster's suit, panting slightly,
allowing his father to dominate him, he was being so forceful; Sans moaned
softly before his mind finally registered that Papyrus was screaming and he
began to try and pull away.
Gaster held him tighter, lifting Sans up in his arms until he reflexively
wrapped his legs around his father’s hips, and Gaster began to rut almost
animalistically up into him, harsh and violent, causing Sans to keen in
pleasure, his head thrown back, their tongues connected by a dark violet strand
of saliva.
Then as though he had made his point, Gaste abruptly released him, curious on
what he was going to do, although he at the very least did not drop Sans,
merely slid him down along his body, allowing Sans to feel every inch of his
father’s throbbing erection.
Sans stumbled back when his father released him, although he was finding it
hard to think, his daddy smelled so good, felt so good, tasted so good, he
stared hazily up at his father with half-lidded eye sockets, moaning softly,
wanting his father’s cock so badly. His heat was starting to become inevitable
rather than just a possibility, his bones were burning, he wanted so badly to
be mounted.
He stumbled a few steps towards Papyrus who was still screaming, and slowly
turned to look at his brother. Daddy smelled good, but so did papyrus. He
turned his fully to stare at his brother, his head spinning. Gaster acted
almost jealous one moment, yet made it clear that Sans was just a toy to break
the next...he stared from one potential mate to the next. Gaster was stronger,
but Papyrus offered more emotional stability. He stared up at his father again,
lust warring with common sense. He started to approach Papyrus with slightly
glazed eyes, intending to untie him.
He pulled the ball-gag back out of his brother’s mouth gently.
"Sans! I- I don't know what's going on.... This is a dream, this is just a
dream. It's only a dream." Papyrus kept repeating to himself. "Sans I just want
to go home with you... I'm... I'm so scared...Sans...Please... pleased...Let's
go home...." He sobbed.
Sans stroked his brother's cheeks, and briefly wonder what would happen if he
tried to Shortcut with Papyrus. "it is just a dream papy..." He soothed, voice
husky.
"Then let help me wake up...." He muttered, voice breaking, tears painfully
streaming down his cheeks
Sans just stared at his brother silently for a long moment and then turned to
Gaster slowly, "daddy...send him back?"
"Oh but Sansy we haven't even gotten married yet... I'm sure you don't want to
send him home so early~" he leaned down and whispered to Sans while grinding
his erection slowly into his son, Sans shivered as his father leaned over him,
trying not to inhale his scent as his eye lights diluted slightly. His daddy
smelled so good...he started to pant slightly and found himself trying to grind
his hips back against his daddy's helplessly. He was so hot...Gaster was also
panting slightly, licking his teeth while Sans shuddered and tried to bite back
a moan, eye lights crossing and he panted, leaning forward to brace his hands
on his brother’s shoulders.

"...this is the day we killed him after all." Gaster continued with a dark
laugh.
The nightmare before Gaster returned. The one that made him change. The one
that started all of this. This was the day it happened. Sans froze, eye sockets
opened almost wide enough to crack and eye lights flickering out. This was the
beginning of the worst day of Papyrus’ life...Sans had been part of the worst
nightmare of his life, and then by the end of the day he would die by his
hand...but he could not allow him to suffer even a moment more.
He turned his head to kiss his daddy softly, putting all the love and pain he
could into the kiss, pressing his tongue gently into his father’s mouth,
putting his all into trying to make his father feel SOMETHING. ANYTHING. He
whimpered desperately as he pressed himself as close as he could, and the
moment Gaster began to wrap his arms around him he pulled away.
Twirling on his toes he slipped away from his father before lunging forward he
made a grab for his brother and with grim determination he took a Shortcut.
***** Marriage Ceremonies *****
Gaster had never been so furious. He tried to grab his sons before they
disappeared, screaming for Sans almost desperately as they were swallowed by
the void, his eye sockets wide as he tried to reach for Sans’ fading form.

Papyrus held onto him for dear life, crying softly into his shoulder. "A-are we
home yet...?" he whimpered as they appeared in his room, the void fading away
from them. Sans carefully settled his rattled brother into bed, tucking him in
lovingly and kissing his forehead as gently as he could, wiping his tears away.
"of course papy. it was all a bad dream...i love you..."
"I love you too Sans... Promise me we'll always be together..?" He smiled at
his older brother, still calming down. Sans crawled into bed with his brother,
holding him gently, rocking him and humming a lullaby while he fell back
asleep, but never once answering his brother’s plea.

He wished he could stay, but Gaster would find them both, take them back. And
he would not be so forgiving. Besides…despite the weight of his sins, despite
his fear and disgust, Sans still loved his daddy.
He took one last look at his baby brother, ingraining the image of him sleeping
calmly into his mind, to treasure. And then summoning all his courage he
Shortcut back to Gaster. He stood shivering with terror, waiting to be dusted.
Gaster was waiting back in his dimension, pacing, almost beyond fury by this
point, he was running on pure feral instinct. Once Sans came back he
immediately grabbed him by the throat and slammed him into a wall "I DIDN'T
GIVE YOU PERMISSION TO LEAVE!" He screamed in wingdings. He lashed a magic
attack at him, slicing open his cheek bone. "Let's just get this over with!" He
was still speaking in wingdings. He forced the ring on his finger and kissed
him before dropping him to the ground. "You're mine now! You're not allowed to
do anything without my permission! You are NOTHING without me! Always remember
that!" Gaster all but shrieked.
Sans was surprised that his father had not dusted him, and all his fury seemed
directed at the thought that Sans was leaving him for Papyrus, in fact he
seemed possessive and jealous more than anything else...and although the
'marriage ceremony' was a little disappointing, he found himself admiring the
ring briefly before shyly looking up at his father. "yes daddy..." he breathed
as he rubbed his femurs together under his dress. He was dripping with arousal,
he was so hot...
Gaster sighed. "And here I thought we were going to have a perfect wedding. But
you had to ruin it didn't you." He side eyed him. "You're going to have to earn
your forgiveness Sans." he growled, but it seemed he was finally calming down
although his eye lights were snapping with sparks and he was breathing heavily.
Sans flushed a bright red at the thought of how he could earn his father’s
forgiveness and his hips twitched. As he slowly stood up he briefly considered
saying that Gaster had ruined their ceremony first by bringing Papyrus, but let
it drop. He walked over to his daddy, head lowered submissively. "i want your
forgiveness , daddy..." he said in a husky drawl as he looked coyly up at his
father, face flushed.
Gaster was pleased by his reaction and held his son close, abruptly seeming
more in control of himself and much calmer, he stroked his fingers lightly over
the gash he had caused in Sans’ cheek, soothing away the pain. "There there it
will all be okay..." Gaster considered him for a moment as he nuzzled into his
father’s hand, eye sockets half lidded. He seemed prepared to make a concession
as he asked softly, "How about we start this whole day over again?"
Sans leaned into his father and nipped at his fingers lightly, happily inhaling
his scent as his eyes lidded until they were bare slits. At his father's
suggestion he shivered and looked up nervously at his father. "whatever you
think is best, daddy...but...please...no papyrus...i...just want you...and
seeing him confuses me..." he leaned further into his father's embrace and
looked shyly up at his face.
Gaster smiled softly "If that's what you want darling. I apologize I thought
you would be happy to see your brother, but I assumed wrong." Gaster seemed
pleased with his answer, eye lights glowing a warmer shade. He waved his hand
and started to bend time. It was morning. Sans was in front of the mirror again
yet he still had all of his memories of what happened
Sans blinked, feeling disoriented briefly as he slowly turned to face his
father, feeling his face flush as he took in his father's appearance once
again. He still felt so hot...
He walked slowly to his daddy, dropping his eyes shyly. He hoped that after
this he would no longer be tortured with his brother. If he could just convince
his father that he wanted nothing more to do with Papyrus, maybe they would
both stop being tortured with each other. He resolutely turned his mind away
from Papyrus, and focused on the monster before him, allowing his lust free
reign so to cloud his mind and make his ruse easier.
"i...hope you like my appearance daddy..." he greeted breathlessly, gesturing
to his ecto beasts.
"You're beautiful sans..." Gaster growled as he leaned down to kiss him
tenderly. Sans leaned into the kiss eagerly, feeling more heated by the second.
He wrapped his arms slowly around his father’s neck, brushing his phalange tips
over his clavicles and neck vertebrae teasingly.
"Shall we get going?" Gaster asked in a husky voice after he eventually pulled
away, his face slightly flushed.

"yes daddy." Sans purred.
Gaster took his hand once again and walked him out of what was soon to be their
room. The chamber he took them to this time was different. They were now in
what seemed to be the King’s Judgment Hall. "I thought a change of scenery
would add more effect" He explained, and Sans nodded thoughtfully, although the
room made him shiver as he remembered some of the darker resets.
Sans let his father lead him, walking as close to his side as he could in the
dress. "it looks lovely, daddy." He looked around to see if it was still a
private ceremony...and briefly worried that his father would find some other
way to humiliate or punish him...
There was no one there. Gaster took both of his hands. "I know it's not
tradition since you wanted it to be private but I'll make it work. Sans... My
son...my darling love..." He pulled out the ring and slowly slid it onto his
finger
Sans looked up at his father with a flushed face, trying to hide how happy he
felt when his father behaved lovingly towards him, and how guilty his happiness
made him.
"I, Wingdings Gaster, as your father, have loved you before you were born,
wanted the best for you; I am the best for you, and I will do everything in my
power to keep you as a happy wife. I promised to be an attentive, protective
husband, to keep you from harm, to give you everything you want or need. I take
you as my wife, to have and to hold, in sickness and in health, until dust do
us part, and even into the void.” Gaster began, his eye lights staring steadily
into Sans and he radiated sincerity as he made his vows to Sans. Sans found his
face heating up and he could not keep the adoration from his eyes as he kept
them locked to his daddy’s.

“And do you, Sans Serif Gaster, promise to be a loyal obedient wife in all
ways, to forsake all others, and bind yourself to me? To be supportive of all
my endeavors, to be whatever I need of you? Will you take me as your husband?
To have and to hold, in sickness and in health, until dust do us part, and even
into the void?"
Sans blushed even brighter and tried to not sound too love-sick as he replied,
"i do."
"Then I pronounce us man and wife..." Gaster cooed as he slipped the wedding
band once more onto Sans’s ring phalange.

Sans leaned forward to kiss his father, eye lights flickering into hearts.
Gaster held him close and kissed him tenderly. "My wife..." He whispered to his
son
"daddy...h-h-husband..." Sans replied, flushing so red that he felt like his
heat was radiating off of him and he ducked his head shyly.
"No need to be so shy around me...." He kissed his cheek "let's go home.."
"f-for...our honeymoon?" he asked hopefully, he was feeling so hot it was hard
to think straight.
He ran a suggestive hand down his father's chest before spinning flirtatiously
away. He gave his daddy a half-lidded look full of lust over his shoulder as
his voice dropped to a husky purr.
" I seem to recall you promised to fuck my brains out..."
Gaster smiled at his son, a hungry smile and his eye lights flickered violently
even though he sounded calm. "Of course... You are getting impatient Sans." He
picked him up bridal style and carried him home
Sans threw his arms around his daddy's shoulders, nuzzling his neck before
licking lightly, squirming against his father's chest. "I can't help it...so
hooot~" he moaned.
Gaster threw Sans on the bed and practically tore his dress off. "Keep your
body..." Gaster growled. Sans gasped when he was thrown on the bed, smirking
with pleasure when his dress was torn off has he had wished, as he had hoped.

A moment later he stopped smirking and he threw his head back with a keening
cry, “ohhh~!” arching into his father. Gaster had grabbed onto the pseudo flesh
of his waist and he had started sucking on his ecto tit hungrily, nipping
lightly before laving the soreness away with his tongue and then suckling as
though trying to breastfeed. Sans heat was finally starting to effect Gaster
and his movements were becoming more animalistic.
Gaster continued to suck on his son’s tits, alternating between them; biting
them softly as his hand trailed down between Sans' legs, pressing into his ecto
body along the way.
Sans gasped with pleasure, but it was not enough. He spread his legs eagerly as
he writhed beneath Gaster, rocking his hips, trying to get the pressure he
longed for. "daddy...don't tease!"
Gaster smirked as he raised his head from Sans’ breasts, mouth entirely wet
with his own drool, and he licked his teeth hungrily. "oh but darling that's
what I do best~" he slowly slid down Sans’ body before leaning down and kissing
his already sopping wet opening. His tongue gently poked at the entrance in a
teasing manner before fully penetrating inside. His tongue was long and
tentacle-like. It filled him up well, not as much as his dick did but still
pleasurable.
Sans started to whine when his father teased him before making a desperate mewl
and throwing his head back when his father thrust his tongue inside his
dripping pussy, his walls clenching around the tentacle-like appendage.
"d-daddy...so....mmmmm....but....please...i....i....need...i want..." he
trailed off, flushing and covering his face with his hands, embarrassed to
admit what he wanted
"You want what Sans?" He pulled his tongue out so he could speak. It was soaked
with his son’s arousal. "No more unless you tell daddy."
Sans squeaked and his fingers tightened on his face and he rocked his hips
desperately.
"i....i...please....it's...." he was hoping his daddy would not make him say
it.
"Then I guess we're done here if you won't answer my request." Gaster sighed as
he started to pulll away.
Sans gave a small wail of despair; he squirmed, so needy, his cunt so achingly
empty, he needed his daddy. He was so needy that he was dripping with lust, a
small puddle of his juices already making a damp puddle between his legs.
He peeked through his fingers shyly. “i….want you...to…” he took a deep breath.
“mark me...claim me in every way…” he slowly slid his hands down his cheeks and
neck, resting them on the curves of his breast as he tilted his head back to
bare his throat before continuing with half-lidded eyes. “wreck me...dominate
me….fuck me senseless…” he flushed brighter and looked away as he got the rest
out in a breathless rush, “fuck me unconscious and keep fucking me, make it so
i can’t walk for a week…” he slid his eyes shyly back to his daddy as he
whispered out what he wanted the most, so desperate that he ached with longing.
“i want to bear your children...please daddy, impregnate me…”
Gaster's face flushed a dark purple and he gazed down at his son with something
like awe. He hadn’t been expecting that at all. Though considering the
sadistically gleeful leer he gave Sans, he was happy to comply. He grabbed him
by the throat and held him off the bed. "And you don't want me to hold
back....? Are you sure this is what you want?" He was crushing his neck,
strangling him. Magic was forming fast in his pants and he hungrily eyed his
son; his wife, begging and pleading for his daddy to wreck him.
Sans’ eyelids slid down halfway and he made a moan deep in the back of his
conjured throat, having conjured tongue, throat, and uterus as well as his
pussy by this point, although this in addition to his ecto-body was straining
his magic a bit; but thanks to his heat he had enough to spare for once. He
reached his hands up to wrap loosely around his daddy's wrists and arched his
spine, trying to grind against his father's arousal as he panted with his
tongue hanging out.
"yesssss.....please...more..."
Gaster ‘s control snapped then, he threw his new wife to the carpeted floor and
attacked him, shoving his length deep inside of his vagina, nearly tearing at
his uterus. He thrusted hard, Sans’ head banged against the floor with the
violence of his father’s thrusts. He summoned tentacles to coil around Sans’
body so he couldn't move until he was finished. Ankles to pelvis were complete
engulfed in a black mass of tentacles, stretching his legs wide for his father,
his arms trapped above his head in a similar mass, his ribs being teased and
yanked, his throat being strangled; he could barely squirm; it was glorious.
Sans gave a gasping wail as his eyes rolled back and he moaned every time his
daddy hilted within him, crying out his enjoyment of the rough abuse. He did
not fight Gaster's hold, but tried to meet his thrusts the best he could as his
mind began to go fuzzy around the edges and he gave himself over to lust,
screaming as he felt something tear, but crying out with pleasure a moment
later, so lost to lust that the pain just inflamed him.

The tentacles were starting to strangle him unconscious while his father fucked
him senselessly
"d-dad-dy…~" he gasped as his vision began to fade around the edges. "so-
good..." he moaned with delight. "don't stop!-fill me with your cum...." he
pleaded.
Gaster was bracing his hands on the floor to either side of his son as he
pounded him relentlessly, his tentacles started to tighten their grip around
his neck as he was slowly reaching his orgasm, filling his unconscious son with
all of his cum
Sans hands tightened around his father's wrist as he was on the cusp of
consciousness, his body arching almost frantically as his father came, and he
came as the blacked out, his pussy clenching greedily as he milked his father
dry, his body convulsing with the violence of his orgasm and he gave a
contented murmur as everything went black.
***** The morning after *****
Sans did not stay out long, the force of his heat had him regaining awareness
less than ten minutes later. And as he had pleaded, his father was still
pounding into him relentlessly; he had flipped Sans over until he was laying
half prone on the floor on his front with his father holding his hips up and
fucking him from behind, growling harshly with every thrust he made, hilting
violently within his son. His ectobody was still formed somehow, so his breasts
pressed against the rough carpet in a delicious friction that he barely noticed
compared to the fucking his sore and over-sensitized vagina was getting. He
wailed as even while he regained consciousness he trembled through another
orgasm.
And yet Gaster kept going, snarling while Sans’ wall clenched like a vice
around him, his fingertips digging brutally into Sans’ pseudo flesh as he
continued to thrust in and out, even against the pressure of Sans’ climaxing
walls, and the forceful stimulation had another orgasm building right on top of
the previous. Sans started to shriek and tried to move from his father’s grip,
tears streaming down his face at the over-stimulation before wailing loudly as
the second orgasms crested and then sobbing when his father finally hilted and
released his hot cum into his vagina, overflowing and dripping down his already
sticky thighs.
Gaster froze above him, panting loudly from exertion and Sans lay limp and
spent on the floor, still sobbing softly. But then as his daddy slowly pulled
out Sans started to whine softly, despite how worn he felt.
“Oh...darling…don’t worry, daddy can keep going....I’m not done with you yet…”
Gaster purred as he gently picked his son up before laying him face down with
his torso on the bed, knees on the floor and ass facing his father, their mixed
cum still oozing from his swollen pussy and Sans grabbed up thick handfuls of
the blanket by his head, grateful to have something to grab onto even as he
arched his back with a needy whine to present himself.
“Daddy’s little boy is such a little slut…” Gaster cooed as he ran his fingers
gently against Sans’ slit, pushing his cum back inside, Sans mewled at the
sensation and rocked back against his daddy’s hand, not denying the claim.
“Don’t worry, Sansy...daddy will make sure you can’t walk for a week, just like
his little boy asked so nicely for…” Gaster continued with a growl as he thrust
two fingers harshly inside Sans’ cunt, causing him to arch his back and cry
out. He thrust his fingers in until he found Sans’ G-spot and kept pounding
into the spot until Sans wailed and came again, but sobbing because he wanted
more.
“daddy...please…” he whined, bucking into his father’s hand as his father
forced him to ride out his orgasm.
“Use your words, baby, what do you want?” Gaster growled, thrusting harder.
“i want daddy’s cock in my pussy!” Sans cried, desperate, not caring how he
sounded. Gaster removed his hand so quickly that he splattered their mixed
juices all over himself, but he did not seem to care as he grasped Sans’ hips
and lined himself up with his son, his cock hard and throbbing again already,
his body in tune with his sweet boy’s heat, and he thrust in with a grunt.
“Good boy, daddy’s good little slut, such a good wife…” Gaster praised in a
husky growl as he began to thrust, a little slower than before, but with more
precision. Sans keened softly at the praise, and moaned appreciatively at the
more gentle pace, able to take the time and truly appreciate the size of his
daddy.
Gaster was not able to keep up such a slow pace for long though, and after only
five minutes he was pounding his son into the bed as hard as he could, his eye
lights dilated and hazy with lust, glowing a deep purple that was almost black
and he panted loudly, long tongue hanging out of his mouth as he mounted his
son who was squirming and whining like a bitch in heat, driving him mindless
with lust.
It did not take long for Sans to be fucked back to unconsciousness, his body
only able to handle so much; and his father did not stop until he too fell
unconscious from magic depletion after cumming so often in his son.
---
Sans woke up slowly, feeling sore all over, but very, very satisfied. He was in
bed with Gaster, his daddy, his husband. He was already cleaned up and in an
old black t-shirt that he assumed belonged to his father. His father didn't
notice him awake. He was in bed looking over notes and finishing equations. He
had a stern look on his face.
Sans heat was not quite done the edge had been well taken care of, and Sans
could feel his lust winding down, but he still felt a little needy, and at the
very least he was still aroused, but one look at his father's face had him
hesitant to ask for help. He suddenly wondered what day it was and how long
they had been going at it, because he remembered coming to a few times, and his
father had still be fucking him senseless; against the wall, on the bed, on the
floor again...his father was so attentive. Sans licked his teeth hungrily, he
wanted more.
But at the same time his father had just become a god, had said something about
gaining control of all the timelines. Obviously he was very busy. He had
already wasted a lot of time on Sans, granted it had been their Honeymoon, but
he could not expect his father to spend every waking moment fucking him...he
squirmed with indecision and need, trying not to whine.
Gaster noticed then that he was awake and slid his eye lights over to him
"What's wrong darling?" he asked gently, affectionately.
Sans took his father's acknowledgement of him as an invitation and squirmed
shamelessly into his father's lap, straddling his father's hip and beginning to
rut desperately. "i need more daddy...please..."
Gaster pushed him out of the way, looking impatient, but not actually upset.
"We fucked for almost a day straight, Sans, I actually passed out an hour ago.
Let me work..." He was putting his notes back in order. "....unless you want to
pleasure daddy as he works, no."
Sans allowed himself to fall on the bed beside his father with only a small
mewl of complaint, but at his father's suggestion he looked up with half lidded
eyes.
"ok daddy..."
Gaster took out a half masted erection in case Sans really wanted some sexual
attention and went back to work.
Sans nestled himself happily between his father's legs and began to lick the
erection lovingly, wrapping his conjured tongue around as much as he could
until the cock was fully engorged before pulling it into his mouth and
swallowing as much down his conjured throat as he could, moaning with pleasure
at the taste.
Gaster shuddered. His pencil fell onto the bed for a moment before he picked it
back up and attempted to write more numbers and equations as his beautiful son
sucked on his large cock. "Yes sans.. Just like that...."
Sans purred when he heard his father's praise and turned his eye lights to look
up at his daddy, eye lights flickering to heart shapes. He began to suckle
hungrily, wanting to taste his father's release.
Gaster continued his notes and science, trembling under pleasure while doing
so. His erection twitched and throbbed in his mouth
Sans just stared lovingly up at his father, enjoying even the smallest reaction
he caused, feeling so happy to bring his daddy pleasure. He wanted his daddy to
cum in his mouth, but after a while his own dripping pussy could no longer be
denied. He pulled himself off with a wet pop, and then before his father could
react he got into his knees and impaled himself with a squeal as he allowed his
legs to collapse and slammed all the way to the hilt in one go, his eyes glazed
over completely and his tongue hung out of his mouth.
Gaster gasped as his notes fell to the ground from suddenly limp fingers, he
arched automatically up into the moist heat of his son’s insatiable pussy. "S-
sans! I didn't give you permission to—" he trembled under his son before
growling ferally and flipping them over as he took control.
Sans felt briefly triumphant as his father trembled beneath him before making a
gasping mewl as his father took control, arching eagerly into his daddy,
reaching out his hands to cling to his broad shoulders.
"unnnnh! yes, daddy! so big!"
“Such insatiability while in heat...your magic reserves are impressive, my
love..”Gaster growled, his male ego stoked by his son’s words and he began to
thrust as hard as he could, hitting Sans’ G-spot every time, grunting as his
son’s overstimulated and used cunt still tightened so lovingly around him.
Sans did not last much longer, and his father quickly filled his son with his
load and kissed him tenderly "Now Sansy... Let daddy get back to work okay?"
Sans keened as he was filled and returned to kiss before pouting softly. "i
told you I was in heat daddy...you should have expected it...besides...you
haven't..." he blushed and turned his head to the side. "marked me..." he
continued shyly.
"Marked you how...? I've cum inside of you countless times?"
Sans flushed and bared his throat shyly.
He chuckled "you want it in your mouth?"
Sans sighed with a pout. "i want you to BITE me daddy..."
Gaster blushed not expecting that "Oh Sans.. You should have said so" he
breathed hungrily.
Sans dropped his eyes shyly. "is what i meant by marking..." he muttered,
embarrassed.
Gaster pinned him to the bed and kissed him. Tentacles coiled around him,
weaving through his rib cage so he couldn't escape
Sans gave a happy mewl and watched his father with half lidded eyes which slid
slowly closed as he leaned into the kiss.
Gaster kissed his cheek and then his jaw, then down his neck before biting hard
on him, worse than Papyrus ever could, his jagged teeth tearing deep.
Sans gasped as his eye lights rolled back and he trembled beneath his father,
writhing at the mixture of pleasure and pain.
He clawed at his rib cage as he sunk his teeth deeper into Sans' neck bone. He
worked his way down to biting parts of his ribs. Sans arched his spine
frantically as he tried to grind into his father, a small moan falling past his
teeth.
"Da-daddy..." he pleaded.
A tentacle pressed against his formed vagina "My sweet, needy little Sans..."
Gaster noticed something as he was marking his ribs but he wasn't going to say
anything yet. He just stayed silent for a moment
Sans spread his legs and tried to rock his hips to cause the tentacle to enter
his still hungry pussy.
"yes, yes daddy...please daddy..."
The curious tentacle slithered it's way up Sans' vagina and tickled his g-spot
Sans gasped and arched his spine more violently, his head thrown back and he
rocked his hips frantically at the sensation.
Gaster went back to biting at his neck, marks were left all up and down his
torso
Sans' eyes slid shut and he made a thrumming purr at the back of his throat as
he went limp, loving his father's rough treatment.
"uhn...daaa~dddy"
The tentacle thrusted in and out in hopes to make him orgasm. He needed to
speak with him
Sans writhed underneath his father, panting slightly.
"more daddy....more..." he pleaded
"Sans..." He panted slightly. "You're pregnant sans.." He pointed to the small
orb of magic in his torso
Sans' eye sockets flew open and he stared at his father in surprise before his
eye lights rolled back and he wailed as he came, clenching tightly around the
tentacle.
Gaster’s magic disappeared and he sat back up to examine his post-orgasmic son.
Sans looked utterly debauched, his eyes glazed and his face flushed and
slightly shiny with sweat, his tongue hung out as he panted and he finally
looked satiated. He was covered in bite marks, some of the deeper ones leaking
marrow. He looked almost indecently pleased with himself.
Gaster nodded. "Get yourself cleaned up. I'll remove the child when you come
back." He stated uncaringly.
Sans froze and stared up with wide eyes, eye lights shrinking to pin pricks. He
opened and closed his mouth several times before managing to speak in a low,
hesitant tone.
"daddy...? i...i want....to carry it...for you....give birth...."
"You actually want to carry this child? I've already raised two children, I
don't have time or patience to raise more." Gaster sounded only slightly
impatient, but was watching Sans curiously.
Sans shifted to sit up, wrapping his arms protectively around the newly formed
soul. "i want to carry your baby..." he growled. "i'll raise it."
Gaster nodded, seemingly satisfied with Sans’ declaration. "Very well. If that
will make you happy."
Sans eye lights flickered to hearts and he threw his arms around his father and
kissed him deeply.
"thank you daddy..."
He sighed and kissed him back "anything for my beautiful wife.."
Sans felt as though this was the happiest moment of his life, and he all but
melted against his father. "i love you daddy..."
"I love you too Sans. I trust you'll keep our family tradition when it comes to
names?"
Sans nodded enthusiastically and grinned. "of course, daddy."
"I'm excited to see what you choose." He pressed a kiss to his forehead "I do
love you, my darling wife..."
Sans smiled happily as he sat up and stretched his arms languidly above his
head; he had been planning to get out of bed to clean himself as his father had
suggested, but the moment he tried to put weight on his legs he collapsed with
an undignified squeak. His father just sighed, but as he came around the corner
of the bed (on legs that also seemed a little unsteady) he looked partially
amused, but also very, very smug.

“Well, my sweet wife, it seems i succeeded in part in causing you to be unable
to walk for a week…” he teased as he bent down to lift Sans into his arms. He
carried Sans to the washstand and lovingly washed him, being thoughtfully
gentle over Sans’ sensitive pelvic area.
Sans just relaxed and allowed his father to clean him. After he had cleaned his
son to his satisfaction he carried Sans back to their bed and sat down with
Sans curled against his chest, running a hand down his spine slowly. Sans' eye
lights became heart shaped again, for a prolonged several moments rather than
just a flicker and curled up against his father's chest.
Gaster held his son and future child close. "I did not think I would ever have
another child... I wonder if it will be another boy?"
Sans glanced up shyly, nuzzling his father's chest. "so you do want it, daddy?"
He sighed and kissed his son's head. "If it will make you happy.. I will be
willing to raise this child with you."
Sans leaned up to gently press his teeth against his father's.
"it will...it will make me so happy, daddy...growing heavy with your
seed....bearing your child..." Sans purred, eyes half lidded. Gaster flushed
slightly but smirked.
"Not only will they be your child but your sibling as well.. A better sibling."
Gaster explained.
Sans felt a twinge in his soul when Papyrus was mentioned, even if it was a
rather oblique mention, but hid the reaction as he leaned into his father,
relaxing and chuckling softly.
"heh...kinda weird...but...i'm looking forward to it..." Sans laughed softly.
"I'm glad. And who knows? It might even be a girl…” Gaster mused thoughtfully.
Sans smiled softly at the thought. "i would like having a daughter..." he
agreed.
"That sounds wonderful Sans…” Gaster seemed excited by the idea.
Sans hummed happily and closed his eyes as he relaxed against his father as he
considered his new life. He loved his father so much, he wanted to make his
daddy happy...he felt a little warm and squirmed slightly, aghast, since he was
pregnant he should not be in heat any more! And he was sure his father was
probably tired and would not want to be bothered with his needs any more…
But too his shock and delight, his father showed every evidence of enjoying his
neediness. He teased him a bit more, but then took care to completely exhaust
him.
***** 2 months later *****
Sans curled up against his father's chest, stroking one hand sleepily up and
down his father's chest before  curling his phalanges into his father's shirt
possessively.

 Gaster rested one hand on his son's growing belly. "They're getting bigger."

 Sans was feeling completely at ease in his father's lap, happier than he had
ever been.

 "who would have thought i would have twins...you're so potent daddy..." Sans
teased softly.
Gaster chuckled a bit nervously. "I have a thing for always making two it
seems."
Sans just leaned up and nuzzled his father's throat lovingly.

 "just too much for your own good, daddy. not that i mind...at least i'm not
craving conflicting foods..."
Gaster smiled and planted a kiss on Sans' cheek. "Is there anything I can do
for you?"

 Sans leaned his head back against his father's shoulder and gazed up at him
with adoration, his eye lights soft.

 "hmm...well...speaking of cravings...." he flushed slightly.
"Hmm? Are you hungry for something?"

 Sans nodded thoughtfully, his grin turning mischievous because he knew what
his father's reaction to what he wanted would be.

 "yea'...you won't like it...." he started with a grin as his eye sockets
became half-lidded. "i want spaghetti covered in mustard with pickles..."
Gaster barely seemed surprised. "Well of course you do. The science behind your
strange request is that pregnancies usually cause the craving of pickles,
spaghetti will cause you a sense of nostalgia that your hormones crave at the
moment and simply you love mustard.

 Sans just chuckled and shrugged before leaning forward to nip his father's
clavicle lovingly.

 "that makes as much sense as anything else daddy..." he cooed sweetly. "you
intend to indulge me?"
Gaster chuckled to himself and kissed his son. "I love you Sans..." He kissed
him even deeper "I love you so much"

 Sans moaned softly and leaned up to give himself up to his father, opening his
mouth wide in submission as he curved his spine to press himself against his
daddy.
Gaster smirked and let his long tongue slide into Sans' mouth.
Sans moaned and writhed against his father, suckling on his tongue.
Gaster pulled back and chuckled. "Now now you're pregnant with two children...
Do you think you should be doing this?"

 Sans licked his teeth hungrily and began to rut into his father's pelvis. "you
started it daddy..." he reminded Gaster.
He chuckled again "it doesn't mean you have to follow Daddy's foot steps~"

 Sans continued to rut into his father, eyelids half lidded and he just
grinned. "but daddy...you make me feel  soo~ good~..."

 "You'll hurt the children dear~" his voice purred as he grinned behind his son


 Sans snorted. "'m only a couple months along...and they are well cushioned by
my magic." Sans explained flippantly.
"It's up to you darling... Daddy has his big cock just dying to be touched~"

 Sans whined when his daddy started talking dirty to him, his eye lights
dilating and he began to rut harder against his father, sliding his hands up to
his father's shoulders to anchor himself for more frantic motions.

 Gaster summoned his giant dick for his son to play with. "My wife... My
beautiful, please won't you be a dear and suck on Daddy?"

 Sans moaned happily at the thought and eagerly slithered down his father's
body until he slid off his lap and settled between his thighs, licking his
father's length hungrily. A long stripe from base to tip, and then he began to
suckle on the tip.

 Two disembodied hands grabbed Sans head and forced him to deepthroat his
father. "Oh Sans~ you've never been this hungry for me~" he kept him down for a
while before forcing him to bob his head up and down

 Sans made a muffled gurgle of surprise when his father's huge cock was shoved
down the throat he had conjured at the same time he'd conjured his tongue. He
gagged momentarily, reflexively trying to pull away, but then he managed to
start swallowing around his daddy's length and his throat stretched to
accommodate the length and he happily went along with the ministrations of the
disembodied hands.

 Gaster smirked at how obedient he was. "Good kitten..." He magically conjured
up a leash and collar for Sans which he proceeded to tug on while being
pleasured.

 Sans was moaning at the taste and feel of his father's cock when he suddenly
felt something leather around his throat and then a tug that had him whining
around his father's length. He peered up at his father lovingly as Gaster's
words penetrated his lust fogged mind and he deliberately purred.
Gaster's length twitched, holding up his jaw. "Yes my beautiful son... Keep
sucking Daddy like that... You're daddy's little slut..." He tugged the leash.
"Swallow all of Daddy's length.."

 Sans whined softly at the mixture of praise and filthy talk and he was all too
eager to obey as he swallowed his daddy's cock until his face was pressed
against his father's pelvis.

 Gaster grabbed his son by his formed throat, squishing it hard around his cock
chocking him. He started moving his hand up in down as if masturbating with
Sans' throat. "How much pain would you go through to make me cum beautiful?"

 Sans gagged briefly when his daddy grabbed his thrust but he adjusted as he
continued to remind himself that as a skeleton he did not actually need to
breathe, he only felt like he was suffocating. He looked up at his father, eye
lights flickering to heart shaped and he wiggled until he was up on his knees
so that he was angled down for his father to have a straighter fuck. Also so he
could start running light phalanges over his pelvis, he was so wet and needy
himself. He gave his father a look of devotion and utter trust, silently
submitting himself to whatever his father desired of him.

 "Look at you... Your mouth full of your father's cock, submitting to me,
pregnant with me, and now masturbating to me using you. How sick.... Don't
stop.. Daddy's getting close." He started thrusting faster. Tentacles swarmed
sans body, entering his eye sockets and his vagina, penetrating hard

 Sans purred as his father degraded him before wailing as he was suddenly
penetrated. He writhed and tried to pull away for a moment before adjusting and
beginning to moan.

 The tentacle was thrusting fast, Gaster was forcing sans to cum fast. Gaster
was getting close. He moaned out as his load released deep in Sans' throat, it
exploding inside of his rib cage and getting his entire body gooey with cum

 Sans eye lights rolled back and he moaned at the taste of his father's release
before wailing through his own orgasm.

 "hnnn~ daddyyyyyyyy~!"

 Gaster's Magic disappeared making Sans gasp. "You're such a good boy..."

 Sans panted softly as he collapsed across his father's lap, humming contently.


 "love you daddy..."

 "I love you too sans..." He pressed his mouth against Sans'

 Sans purred softly and returned to kiss, content to just stay as he was for
awhile. After a few minutes he pulled away and sat up, stretching languidly.

 "well, now that I've had my breakfast," he started, only half teasing, "what's
on the docket today?"
"Well today i have a lot of personal experiments to work on. I'm sure you'll be
fine on your own with the children?" He gestured to his baby bump "I won't be
far if you need me."

 Sans rubbed his hand happily over the bulge, feeling them react to his touch,
pulsing slightly and shifting within his womb to get closer to his hand.

 "well...i think i want to go take a long bath and do some reading, i want to
catch up on my quantum mechanics," he mused thoughtfully.
"Quantum mechanics?" Gaster smiled a little "I didn't know you were taking an
interest~"

 Sans looked to the side shyly and shifted his weight, he may had forgotten to
bring up that he had been studying advanced physics.

 "well...i...want to help you..." he whispered.
Gaster had a very genuine grin on his face. "Well, I would be more than happy
to help you with your studies if you'd like."

 Sans looked up at his father eagerly and slid to lean into him, eye lights
flickering into stars of excitement.

 "oh, i've been having trouble understanding the most recent premise in the
electromagnetic fields...
Gaster smiled and took his hand. "Here lets go to my lab, I can help you with
that.. Visuals are easier to understand and more fascinating”

 Sans laughed and tugged at his father's hand slightly.

 "lemme get dressed first daddy!" he teased.
"Alright if you wish.."

 Sans snorted and twirled coyly away from his father. "you know quite well you
don't like anyone else seeing me naked..." he huffed.
"No one else is in my lab right now. I know how to take care of my property
Sans." His fingers trailed along Sans' jaw bone

 Sans turned his head to the side slightly and nipped lightly at his father's
finger tips while purring. He looked up at his father underneath half-lidded
eye sockets.

 "well, i do have that new dress i wanted to wear..." he suggested.
"You really want to distract me from my work don't you darling?" Gaster pulled
him into another kiss

 Sans purred and leaned into the kiss before pulling away.

 "i can't help it daddy...if i could have your cock in me all day i'd still
never have enough..." Sans admitted coyly.
"Hmm. Alright." He had an idea, an idea that would mainly be for his amusement.
"Come to the lab with me."

 Sans looked up at his father hopefully and obediently followed, not bothering
to get dressed.

 "I have an idea that will help with my work and keep my sweetheart entertained
at the same time." They entered his lab. "Sans hop up on this bed."

 Sans flushed eagerly, pleased by the endearment and excited to see what his
father had in store for him. He scrambled onto the bed.

 Gaster strapped him to the bed tight so he wouldn't be able to squirm. "This
way I can continue my work and you can just sit there tight until I'm done.."
He snapped his fingers and purple magic formed between Sans legs in the form of
what seemed to be a dildo though it was shaped and sized exactly like Gaster's.
It impaled his forming vagina and started thrusting in and out 5x as faster
than Gaster ever could

 Sans panted slightly when he was tied to the bed looking up at his father's
eye lights trustfully and moaned when he saw the dildo before throwing his head
back with wail as he was impaled.  Was immediately reduced to a drooling
sobbing mess.

 Gaster smiled and turned away. "Keep moaning my precious slave, it's music to
daddy's ears. Please do tell me when you want to start your lesson, or else
this won't stop until I command it to. Even if you cum 26 times in a row." He
smiled and sat down in his chair continuing his experiments.

 Sans was almost incoherent by this point but he still managed a shaky nod as
he whimpered. Soon after he lost all ability to think clearly at all. He could
only writhe and moan, calling out his daddy's name periodically.
Gaster was able to get some work done, loving the sounds and screams Sans made
as he worked "now now I'm going to have to start doing this often. Hmm... How
about I make it bigger." The magic stretched,  making sans feel like he was
going to break

 Sans started to sob as the appendage stretched inside him, his walls burning
as they tried to fit the increased girth.

 "Hnaah- too...biiiig~" he wailed, but his hips still bucked into the motions
and his eye lights were glassy.

 "I'm sorry bigger? Is that what you said?" Gaster purred as he extended the
magic slightly larger

 Sans screamed, arching his back, eye sockets shot wide and eye lights
flickering frantically, a trickle of drool at the corner of his mouth. He
spread his legs as widely as he could in a futile effort to fit the increased
size.

 "daddy please~ it hurts!" He sobbed.

 Gaster grinned widely in pleasure. "Now now sans, not until you cum for
daddy~"

 Sans gasped, eye sockets filled with tears of pain but he nodded and tried to
arch his hips to angle the huge pseudo cock to hit his G-spot, more drool
trickling from his mouth and he whined in a mixture of pleasure and pain.
"Good boy sans.... Take it all.... Cum for daddy.."

 Sans turned to stare at his daddy, eye lights flickering to hearts despite the
pain and with a wail he came on command.
Gaster grinned satisfied. "Now then. Will you behave enough to help me with my
experiences or should I leave you here?"

 Sans moaned tiredly, hips twitching as he came down from the violence of his
orgasm. He nodded and shifted, tugging at his restraints.

 Gaster untied him. "Now retrieve your clothes. I'll be waiting at my station."


 Sans nodded obediently and shifted, wincing in pain, the increased girth had
cracked his pelvis a  little, but he did not want to disappoint his daddy so he
slipped off the bed and almost fell as his legs collapsed.
Gaster chuckled with cruel amusement and turned to just leave him there.
