***** Chapter 1 *****
Sans felt it as soon as he woke up. His entire body felt heavy and sluggish.
Was he getting sick? He didn't want to miss out on working with his dad in the
labs. Sure a lot of things that he works on is confidential. However that
things that are not, he is allowed to look over and help with. It is so fun!
Sans smiled to himself as he got dressed. Today was going to be a good day. It
just had to be!
 
~```~
 
Gaster placed breakfast in front of his youngest, turning his gaze up towards
the ceiling. What was taking Sans so long to wake up? Normally his oldest was
up and downstairs before anyone. Pouring his coffee, he was tempted to go wake
him. His thoughts went over to his current project. Things was not working out
and he was honestly running out of solutions. He could tell that King Asgore
was losing his faith in the project. The longer that no progress was made, the
higher the chance that the project was going to get pulled.
 
Determination.
 
It was something that they managed extract from the humans. Both body and soul.
If his notes are correct, and they are 90% of the time, he believes that if
there is a child born of a Monster with human DNA-
 
A familiar scent tickled his nose, before Sans entered the kitchen.
 
"mornin' dad, pap."
 
Gaster looked at his son and discreetly sniffed the air once more...'Things
might actually work out after all!'
 
"We do not have a lot of time this morning, Sans."
 
 "i'm sorry dad." He didn't mean to close his eyes again, but it happened.
Sitting on his bed in the middle of getting ready, quickly turned into him
laying down with his feet still on the floor. He ended up sleeping for another
40 minutes.
 
Gaster didn't bother answering Sans, he just finished up his coffee and cleaned
up Papyrus' plate.
 
Sans scrambled to find something small to eat so that he wasn't going to fall
behind. 'looks like breakfast is going to be a cinnamon bunny.' He crammed the
sweet treat into his mouth and managed to put his shoes on right as Gaster was
leaving.
 
It didn't take long to walk to the Lab since they lived in these houses that
was for the Royal Scientist and the like. They stopped by the daycare inside of
the Lab, and dropped Papyrus off.
 
Sans thought that it was odd that all the older Monster's was looking at him.
More like staring, honestly. It made his soul shiver and he didn't like it.
Sans let out a tiny sigh of relief when they made it to Gaster's private
office.
 
"Sans."
 
"yes, dad?" Sans paused in grabbing his lab coat.
 
"I was thinking of having you help on something different today."
 
"am i doing paperwork?"
 
"Not today. I need your help in a more important project."
 
"sure dad, anything you need help with!" Sans could barely contain his
excitement! 'dad never asks for my help on anything important.'
 
"Come with me. You do not need your coat today."  Gaster led Sans out of his
office and deeper into the lab. He stopped in front of a door that had a keypad
on the right side. There was another panel that was at eye level, but it didn't
have any buttons. He typed in a ten digit code and pressed his eye socket onto
the higher panel. His magic flared briefly, then the keypad beeped 3 times.
 
The room was large with many different devices that both looked familiar and
unfamiliar to Sans. He wasn't sure how to feel about this room. Any complaints
was sure to get him booted out of whatever he was going to help with, so he
kept his thoughts to himself.
 
"Have a seat on the table, Sans. I need to fill in some quick paperwork, then I
will be right with you." Gaster didn’t bother turning around as he made sure
the door latched closed. He walked over to the desk he had, scanning it for a
fresh form. There was tons of half filled or failed forms scattered all over
the desk. Giving a tiny irritated huff, he scooped them all up in something of
an organized pile. Spotting a blank form, he placed it onto a clipboard and
grabbed a pen.
 
"Tell me Sans, how are you feeling today? Both emotionally and physically,
please."
 
The teen looked surprised at the question, but answered quickly. "emotionally
i'm feeling pretty good, happy even. physically... i feel a bit tired? and a
little hot? i might be getting sick, but i feel fine. i promise."
 
Gaster nodded as he started to write on the clipboard:
 
Emotional State: Great
Physical State: Normal {Note: From the subject's scent I initially thought that
his heat would not start for at least 4 more days. However it seems that I have
less than 2 days, perhaps even this time tomorrow, before he'll be in the thick
of it. First heats are always a bit unpredictable, anyways.}
 
"Alright Sans, I need you to lay back on the table and expose your soul to me."
 
"w-what? why do you need to s-see that dad?" Sans was surprised. He placed his
hands over his trembling soul, genuinely confused.
 
"Do you still want to help me? Or are you changing your mind?"  Gaster didn't
bother hiding the irritation in his voice. His son knew how much he hated to
waste his time. And that's exactly what he was doing.
 
"i still want to help. i'm sorry dad." Sans laid back on the oddly cushioned
table and summoned his soul forth. It felt weird that his soul was just out and
floating above him.
 
Gaster took a moment to read Sans stats and wrote them down:
 
LV: 1
HP: 10/10
 
Subject LV is naturally at 1. However the HP level is troubling. His HP should
be higher than 10 at his age. It seems I do not have that much room for error.
 
Gaster continued to record the rest of Sans stats, adding little comments here
and there. "You can put your soul away now." He said as he wheeled a machine
over. It was a flat screen with an array of buttons and dials on a separate
lower panel. He turned it on and grabbed the plastic tube with a flat end that
was attached to the machine. "Lift your shirt."
 
Sans hesitated a bit, but did as he was told. Gaster pressed the plastic tube
against his blue belly, adding a little more pressure as he moved it around. He
pressed a few buttons on the machine, several pieces of paper came out. Gaster
turned the machine off when it was done.
 
"You can lower your shirt now."  He said as he looked over the ultrasound
pictures. Laying the picture back down on the machine, Gaster picked the
clipboard back up.
 
The Subject's uterus is in great condition, as it should be. However it is on
the small side and it might cause pain in the later months of gestation.
 
As he was adding the picture to the paperwork, the phone on his desk rang.
Scoffing softly, he walked over to answer it.
 
Sans watched his father talk on the phone. He wanted to ask what that machine
was for, but he knew that his dad was irritated with him. He focused back on
Gaster after he hung the phone up.
 
"Just one more thing and then we are done here for today, Sans." Gaster walked
over to a cabinet that had grayed out windows and opened it. He took a jar out
and discreetly tore the label off, jamming it into the pocket of his lab coat.
Shutting the cabinet, he made his way back over to Sans.  "Take this cream and
apply it along your neck and wrists."
 
Sans did as he was told, taking minor note of the oddly neutral scent of the
cream. 'is this supposed to help me get better? i never used a cream like this
before.'
 
Gaster picked the clipboard back up, quickly adding some more notes to the
paperwork.
 
I administered prescription level Cedapein scent blocker to the Subject. As I
mentioned before his heat will most likely start sometime during the night.
With the Cedapein his scent will not change and garner any unnecessary
attention. If he manages to burn through the Cedapein before the morning, I
will personally apply more before we come back to the lab.
 
He placed the clipboard back on the desk and walked back over to Sans. "We are
done for today, Sans. You can go get your brother and go home." He grabbed the
cream jar from Sans.
 
Sans was confused, but he understood. Some days he had to work harder than
others. 'it seems like today is one of the easy ones.' he thought as he left
the room.
 
XxxX
 
Gaster only stayed at the lab for a few extra hours. Most of them spent
preparing for the next few days. 'Papyrus should be in bed by now. I'm not sure
about Sans, but it would still be important to check in on him.'
 
All the lights was off when he walked into the house. He was pleased to note
that the only scent that he was picking up from his oldest was leftover this
morning. 'It's was like he never came home.' It wasn't like he doubted the
success of the Cedapein, it was just exhilarating to know that its working so
well.
 
He peaked into Papyrus' room first. The child was fast asleep. Although it was
evident that he had gotten up sometime before he fell asleep. There was toys
both on the bed and the floor. He pulled the door closed and walked a few feet
to his oldest room. He gave a light knock just encase Sans was still awake.
 
Nothing.
 
Opening the door, he shivered as his son's undiluted scent hit him full force.
'It's not new. Must be from this morning.' Sans was sleeping but it was
troubled. He was tossing and turning, letting out an occasional pained whimper
or moan. He was sure that Sans heat had started, but he had to be
absolutelysure.
 
He quietly made his way over and pulled the sheets back. 'It seems that he was
getting overheated before he even went to bed.' Sans had on a thin shirt and
his boxers. Both was soaked through. Shirt with sweat and boxers with some of
the sweetest smelling nectar he's scented for a while. 'I'll have to apply some
Cedapein to his thighs before we leave in the morning.' Not bothering to
replace the sheets, he left Sans room.
 
Gaster grabbed one of his many notepads and began recording his recent
findings.
 
'This is going to work. I just know it.'
 
***** Chapter 2 *****
Chapter Notes
     I don't normally crank a chapter out this fast, but you guys have me
     in a special mood with the amount of attention this has been getting.
     Also today is my birthday! And I decided that today is also YOUR
     birthday!! Here is your gift! Enjoy. :3
Gaster woke up a little earlier than he normally did. There was too much riding
on the next few days to mess anything up. After getting dressed, he went to go
wake Papyrus up.
 
"Papyrus, wake up." The child whined and turned away from Gaster, trying to
sleep some more. "Now. This is not optional." Paps whined again, but he sat up.
Satisfied that his youngest was awake, he left the room. He looked at Sans'
room. 'Not yet.' He went and made Paps breakfast first. He filled a large bowl
with warm water before going back upstairs. He poked his head back into
Papyrus' room. He was getting dressed.
 
He went into the bathroom and sat the bowl down. He pulled a neutral scented
soap and added a few drops to the water in the bowl.
He left out and quickly grabbed the Cedapein that he brought home with him and
two towels. Paps was just standing in the hall when he came out of the bathroom
with the bowl.
 
"DAD?"
 
"Yes, Papyrus?"
 
"I-IS SOMETHING WRONG WITH SANS?"
 
"He's just a little sick. I'm still going to take him with me to the Lab. Do
you think that you can be a big boy and stay at home by yourself today?"
 
Papyrus' eyes was wide. He had asked a few times before, because 5 was
basically an adult, but he was always shut down. "I CAN STAY ALONE TODAY. TH-
THANK YOU, DADDY!" Papyrus slammed himself into Gaster's legs.
 
The older skeleton bit back a curse when he almost spilled the soapy water in
the bowl. "Yes, well go eat your breakfast and leave me to care for Sans."
 
"ALRIGHT DADDY!"
 
Gaster watched Papyrus race down the stairs and out of his sight. He wasted no
time going back to Sans room. He knocked softly and got a whine, instead of an
answer. He let himself in. He could smell it wafting from under the door, but
letting the scent hit him full force, made his mouth water. 'The Cedapein must
still be working. His scent is not as strong as it should be. However he is
still too noticeable.'
 
"Sans."
 
The teen's eye's slowly rolled over and locked with Gaster's. After a few
seconds of staring, it finally clicked that his father was standing in his
room. He must be late getting up!! Sans sat up quickly, only to lay back down
when the room started spinning.
 
"dad... i-i think i might be really sick..."
 
"It's alright Sans. I'm here to help you." Gaster sat the bowl of soapy water
on the nightstand."I'm going to get you cleaned up and then to the lab. When we
get there, I'm going to fix you right up. Have you as good as new in no time."
He quickly peeled the sheets off of Sans, not waiting for an answer.
 
He eased Sans boxers off, ignoring his sons flustered mumbling. Gaster was
almost disappointed to note that the fabric in his hands was more damp with
sweat than slick. He gave Sans thighs and intimate places a quick wash. He had
to work fast, since he had no idea when Sans heat might flare. He opened the
Cedapein and smeared a small amount on both thighs, before wiping his hands on
the second towel that he brought with him.
 
"d-dad...?" sans whined, pressing his legs together.
 
"It's going to be alright, Sans." Gaster answered back as he stood up and
walked to the other side of the room. He pulled out a simple outfit from the
dresser. He carefully put the t-shirt over Sans head and worked his arms
through. He was more cautious with the underwear and jeans, being sure not to
linger. Sans didn't complain the entire time. Gaster knew that he had to be
cutting it close.
 
He took a quick sniff of Sans and frowned. His scent was still bleeding through
a bit. He unbuttoned his shirt and placed it on Sans. It was a little too big
on him, but it would have to work.
 
"Just a moment Sans." Gaster breathed as he left the room. He grabbed another
shirt and quickly buttoned it up. He picked up the notebook that he was writing
in last night and went back into Sans' room. The teen was standing in the
middle of the room, looking down at his hands that was still covered by the too
long sleeves.
 
"dad... why i'm i wearing your shirt?"
 
"You asked me for it. I think that it looks good on you." Gaster answered as he
stuck the small book in his back pocket. He knelt in front of Sans and began to
roll up the sleeves. "There, that's better. Let's go now, Sans."
 
Papyrus had finished eating his breakfast and was playing on the floor when
they came downstairs. He let out a gasp of excitement at seeing Sans.
 
"W-WOW SANS! YOU ARE LOOKING COOLER THAN U-USUAL!!"
 
"thanks paps." sans beamed a bit as he put on his shoes. "come on papyrus. do
you want me to help you with-"
 
"DAD S-SAID THAT I CAN STAY HOME ALONE TODAY."
 
Sans looked over at Gaster, but he was not acknowledged. "Alright Papyrus.
There's plenty of food in the kitchen that does not need to be cooked. Behave
yourself. Come along, Sans."
 
The teen wanted to complain and insist that Papyrus needed to come with them,
but the last thing that he wanted to do was make his dad upset. Everything
would be fine, even if it didn't feel like it would.
 
~~~
 
Sans almost had the feeling that his dad was in a hurry. He was walking fast,
but never leaving him behind. It was odd, but how he was feeling was even
weirder. He felt really hot and tired, but he was also hungry and wide awake.
He was trying to think of all the sicknesses that he knew about, but now that
they were in the lab, his thoughts was getting fuzzy again.
 
Some idiot stopped them on the way back to the secured room. Gaster tried not
to blow the poor assistant off, but his mind quickly shot to the fact that he
was running on borrowed time. Sans was starting to look flushed and Gaster
mentally cursed. He snatched the folder out of the assistant’s hands. "Thank
you for the update. You may continue on." He grabbed Sans sleeve, pulling him
along as he started walking away. If he didn't have to stop, Sans would've been
tucked away by now. He was starting to get antsy. He knew that some of the
scientists have either figured out that Sans is in heat, or they're about to.
Quickly tapping in the code for the room and scanning his magic, he nudged Sans
inside. He let out a sigh of relief as soon as the door latched shut. Sans
whimper made him quickly whip around. He was flushed and looking faint. Gaster
wasted no time scooping Sans up.
 
"Don't you worry about a thing Sans. Daddy is going to take good care of you."
He breathed softly to the barely conscious teen. He laid Sans onto the same
table as yesterday, and walked over to a refrigerating unit. He pulled out a
small clear bottle that had a slightly pink liquid swirling around in it. He
opened it and dipped an eyedropper inside, filling it.
 
"...dad, i'm-i'm really hot-t..." Sans called out.
 
Gaster walked back over to Sans and gently pried his mouth open. "Lift your
tongue, Sans." the teen whined, but did as instructed. Gaster emptied the
eyedropper in Sans mouth and then walked away. After the liquid was put away
and the used dropper cleaned, Gaster walked back over to Sans. Sans' eyes was
open, but they were unfocused.
 
Gaster smiled widely. 'The sedative is working wonderfully! Now I can have an
uninterrupted start.' Sans let out a confused whimper, Gaster rubbed his hand
over the teen's head in a soothing manner.
 
"It's going to be alright Sans. Daddy is going to take real good care of you."
 
***** Chapter 3 *****
Chapter Notes
     This is where things start to get ugly, so please if this is not your
     cup of tea, please leave. Thank you.
     On another note, I want to thank everyone that's been giving this
     story love. You are the reason I continue to write. Please enjoy. :3
Gaster only had a vague clue as to how long the sedative was going to be
working through Sans' system. It was only tested on one other monster and he
was only minutes from turning to dust. It was a shame that he didn't get to
test the sedative again before now. He walked over to another bed that was
covered and snatched the sheet off of it. He transferred the limp teen onto
this new bed. It was wider than the one that was used the day before, and it
had five leather restraints screwed into it. One for each limb and one that
went across the forehead. Sans was too short to use the forehead restraint, not
that he would need it. The other four was more than enough. He pulled both
shirts off of Sans before securing his wrists in the straps.
 
Sans went from confused to scared. He trusted that his dad was going to cure
him of whatever sickness that he had, but all of this was brand new. His dad
didn't ask or say anything about him needing to remove his clothes, so why was
he doing it? Whatever his dad gave him made his body feel too heavy. His tongue
barely twitched in his mouth, so talking was out for the moment.
 
Gaster folded the shirts and sat them in a tray that was near the end of the
bed. Sans shoes was placed on the floor and nudged under the bed. Socks added
to the tray as well as his pants. He decided to leave the boxers on for now. He
turned away to collect the materials to wash the Cedapein off, since he wasn't
going to need it any longer. A thump against the bed made him turn around. Sans
left leg was in a different position. He watched as the boy's finger's twitched
and he weakly kicked his leg again.
 
Interesting!
 
"I am amazed Sans. You shouldn't even be able to do more than breathe and look
around the room right now." He watched his son struggle for a few more moments
before going back to what he was doing. It wasn't like Sans was going anywhere.
He had to improvise with the soap, but it didn't matter as long as most of the
scent blocker was washed away.
 
Sans flinched weakly and tried to get away from Gaster's hands when the older
male started to take his boxers off. "......nnnn-oooooo..."
 
"Don't start being a brat now, Sans." Gaster answered back, taking off Sans
last article of clothing with ease. He washed all the places that he applied
Cedapein to and then some. He smiled as Sans sweet scent immediately started to
bleed through. "Everything is almost ready Sans. There's one more important
thing to do before we get started."
 
Gaster walked over to a refrigerating unit and took out a syringe that was
already filled with liquid. He walked back over and showed the new item to
Sans. "With this we are going to free all the Monster's from the underground.
Aren't you glad that you volunteered to help me achieve our freedom??" There
was confusion written all over Sans' face. "You are apart of the biggest
experiment that I've done to date. Other than the core, of course." Gaster
explained as he uncapped the syringe. He used his free hand to press against
Sans' lower abdomen a few times before sticking the needle into the last place
he pushed.
 
"...ugghhh..." Sans felt a sharp pinch on his stomach and his body twitched
harder because of it. Whatever Gaster was injecting him with didn't feel like
anything magical. More drugs???
 
"You are ready now." Gaster placed the empty syringe on a nearby tray. Without
warning he picked up Sans' right leg and pressed it against the teen stomach.
"Now we can get right to the fun part."
 
"no d-don't..!!"
 
"It would be best if you do not make me angry."Gaster growled as he shoved two
fingers into Sans.
 
Sans let out a scream as his arms rattled in the restraints. 'what? why? why??
hurtshurtshurtshurtshurtshur-'
 
"STOP SCREAMING! Or I will have to gag you. In fact, I'll do it anyway." Gaster
pulled out his fingers long enough to take off his tie, ball it up, and jam it
into Sans' mouth. "I'm being nice to you, Sans. So relax and let me take care
of you." He stuck his fingers back inside and spread them out, trying to get
Sans ready faster. His scent was messing with his head. Sans was producing more
slick now, so it should be fine to continue.
 
He climbed into the bed with Sans, settling between his legs. He rubbed over
his crotch a few times before undoing his pants and pulling his dick out. He
purred as he brushed his mostly hard dick over Sans' entrance.
 
Sans jerked his arms hard enough to rattle both his bones and the restraints.
His legs was still too numb to do anything more than twitch uncontrollably in
any direction.
 
Gaster brushed over Sans' entrance a few more times before pushing himself
inside in one continuous thrust. Gaster took a brief moment to collect himself
before continuing. Sans was almost too tight, but he was already inside. It
would be counter-productive to back out now. He ignored Sans' muffled screams
of pain and kept thrusting. With how tight the teen was squeezing him, he knew
that he wasn't going to last long. With one last thrust, Gaster shot his seed
deep inside of Sans.
 
Sans was close to passing out at this point. Just when he thought the pain from
before wouldn't get any worse, it did. It got so much more worse. He was sure
that he was close to dusting. And when that didn't happen, he was wishing that
he would. Underneath all the pain he felt that weird feeling coming back. He
tried to focus on it, squeezing his eyes closed tightly. He started gagging
when the hot liquid burned his insides. It seemed to settle that weird feeling
a little. It was still there, but it wasn't making him feel as sick.
 
"Good job, Sans." Gaster praised as he pulled himself out and tucked his dick
away. He got off the bed and grabbed Sans' folder.
 
Subject managed to burn through some of the Ail tranquilizer, but it is still
going strong in his system. Despite being in heat, the subject struggled and
fought me during the entire mating process.
 
He paused to grab Sans' leg, lifting it up and looking at his entrance.
 
There is minimal amount of seed leaking out. This is good. As this is the
Subject's first heat, I will not know if conception has taking place until a
week after it has ended. Any other attempts will be known immediately due to
the abrupt end of said heat.
 
Gaster summoned Sans' soul and read his health. He cringed slightly.
 
Subject's health is currently 3/10. I might have been a bit rougher than I
originally thought.
 
Sans body suddenly went slack. Gaster wasn't worried only for the fact that he
was looking at Sans' health when it happened.
 
Subject has now lost consciousness. While sleep might help his health, I will
feed him upon waking. I'm unsure how much longer the Ail tranquilizer will be
present in the Subject's body. As a precaution his legs will now be placed into
the restraints.
 
Gaster secured each leg in the leather restraints, giving him a small amount of
slack. 'I hope that you conceived, Sans. I'd hate to have to try again during
your next heat. With little to no new information to work with, that is.'
 
***** Chapter 4 *****
Chapter Notes
     Sorry for taking so long to get this up.
It's been a week and Sans' scent is finally evening out. It was both easy and
difficult to keep Sans in the locked lab. The only one that put up a fuss was
Papyrus.
 
**flashback**
 
It wasn't very late, but he had to go home and check on Papyrus. The boy was
standing on the couch, playing some game when he walked in.
 
"Papyrus."
 
"HELLO DAD."
 
"I see that the house is still in order."
 
Papyrus ran over, his smile morphing into a frown. "DAD, W-WHERE IS SANS?"
 
"He's still at the lab. We are doing something very important right now. I only
came home to check on you. I will need to return soon."
 
"O-OH..." Being alone all day sounded fun, but nighttime?? He didn't think that
he'd ever have to go to bed while the house was empty. "C-CAN I COME SLEEP ON
THE COUCH I-IN YOUR OFFICE?"
 
"No Papyrus. You are just fine staying at home. Do not stay up all night. I
will be back to look in on you." Gaster left before Papyrus could complain
anymore. His youngest was fine with that explanation until the third day that
his brother didn't come home with him.
 
"D-DADDY! WHY IS SANS NOT C-COMING HOME?"
 
"I told you that he is busy."
 
"YOU ALWAYS S-SAY THAT. H-HOW COME HE'S T-TOO BUSY TO COME HOME, B-BUT YOU
ALWAYS H-H-HAVE T-TIME? S-S-SHOULDN'T BE THE O-OTHER WAY A-AROUND??"
 
Gaster frowned. 'It seems that Papyrus is a lot brighter than I originally
thought...' "Papyrus, you're grounded. You know better than to talk back to me.
No television for the rest of the week." He ignored Papyrus' cries and
apologies as he unplugged the TV. He took it upstairs and put it in his office.
His home office was always locked. He took a moment to look at Papyrus as he
threw a fit. He went back to the lab without acknowledging his crying son
again.
 
**end flashback**
 
That happened two and a half days ago. He planned on giving Sans another
examination and then sending the boy home. Anything to get Papyrus from whining
at him every time he went home. "Sans, are you awake?" His son stopped looking
at him after the first day. He didn’t care about that. He could see that Sans
was awake, he was just ignoring him. He will have none of that. He slammed his
hand next to Sans' head, making the teen jump.
 
"You will answer when I am talking to you, understood?"
 
"...yes, sir..." His voice was raspy with disuse.
 
"Good boy, Sans. I'm going to undo your restraints. After a quick examination,
you can go home." Whatever Sans was going to say didn't matter, he was already
undoing the leather straps.
 
"....w-why...?"
 
"What?"
 
"why did you d-do t-t-this?"
 
"Your heat made you a perfect subject."
 
"m-my heat??"
 
"That's what I said Sans. Your heat made you more fertile than normal. While
conception is not guaranteed, the chance of success is significantly higher."
 
"conception??" Sans voice squeaked out. While he didn't know what a heat was,
he knew what the word conception meant. "...but i can't conceive."
 
"You can and hopefully you did. If you didn't, then I will keep trying until
you do. Now sit up and tell me how you feel. Both physically and emotionally."
 
"my bones ache, i'm hungry and i feel like i can sleep for the next two days...
emotionally... i want to sleep."
 
The subject is feeling minor aches and pains in his bones, due to the fact that
he was immobile for the better part of six days. He is emotionally tired. Most
likely from not understanding his heat. I will give him a book to read so that
he understands better.
 
"Is the pain too much to walk home?"
 
It almost was, but Sans didn't want anything else that his father had to give
him if he could help it. "no sir. i'll be fine." By the force of will alone
Sans managed to stay on his feet when he got off the bed. He got dressed with
the new clothes that Gaster gave him and took a few steps under his watchful
gaze.
 
"It seems that you are fine. You may leave... And I'm sure that I don't need to
remind you, Sans, that you are not to speak a word of what happened outside of
this room. Or do you want to be responsible for the fact that the monsters are
trapped underground for the rest of time?"
 
He didn't. He knew how much Papyrus wanted to see the surface. Most of his
favorite books talked about the surface. He wouldn't be able to take it if
Papyrus was stuck underground his whole life. He would do anything for his
brother. "... i understand, sir." He moved a little bit faster than was
comfortable and went home.
 
Papyrus seemed to be on the verge of a nap when Sans walked into the house.
 
"SANS!" Papyrus scrambled off the couch and slammed into his brother. Sans
stumbled, but managed to stay upright.
 
"careful there pap."
 
"I-I WAS S-STARTING TO THINK THAT YOU WASN'T GOING TO C-COME HOME."
 
"why did you think that?"
 
"DAD SAID T-THAT YOU WAS TOO BUSY TO C-C-C-COME HOME. Y-YOU DON'T H-HAVE TO GO
B-B-ACK TO THE L-LAB, D-DO YOU?"
 
Sans softly rubbed the top of Papyrus' head, comforting him. "course not,
babybones. d-d-dad doesn't need me again for a while. now if you don't mind, i
want to go shower and maybe go to bed.
 
"O-OH, OKAY." Papyrus couldn't hide the disappointment in his voice.
 
"you know pap, what do you say about us having spaghetti for dinner?"
 
Papyrus let out a tiny squeal, nodding his head. "CAN W-W-WE?"
 
"sure can. then later tonight, i'll read you whatever you want me to read."
 
"I'M G-GOING TO C-CHOOSE MY B-BOOK NOW!" Papyrus squealed out, running up the
stairs.
 
Sans smiled fondly and then grimaced. The pain in his legs and hips made itself
known again. He forced himself up the stairs and into the bathroom. A shower
was out of the question since he was sure that his legs was going to give out
any moment now. A bath it was then.
 
~~~
 
Sans had no clue how long he was in the bath, but there was frantic knocking at
the door. He jumped and curled in on himself. Maybe if he ignored it, it would
leave.
 
"SANS? A-ARE YOU ALRIGHT??"
 
It took Sans a few seconds to realize that it was Papyrus talking to him
through the door. "...y-yeah. is there something wrong, pap?"
 
"I-IT'S BEEN A-A LONG T-TIME S-S-SINCE YOU W-WENT IN THE BATH."
 
"i-i must have fell asleep. sorry pap. i'll be out in a few minutes." 'did i
fall asleep?? it doesn't feel like i've been in here for that long...' The
water was ice cold when it was nearly boiling hot when he got in. When he came
out the bathroom Papyrus was standing there, waiting for him.
 
"S-SLEEPING IN THE B-BATH IS DAN-DAN-DANG -NOT SAFE, SANS."
 
"i know, pap. i'm sorry. you ready for dinner now?"
 
"YEAH."
 
Papyrus was so excited that Sans let him help in the kitchen. Help mostly
consisted of Pap just watching him do the prep work, or he asked Pap to pass
him something that was already on the counter. Sans felt like he only blinked,
but Papyrus was yelling at the top of his lungs.
 
"-ANS! SANS!!!"
 
Sans jumped, dropping the knife that was in his hand. "pap, wha-" the food was
burning! He turned the sauce off and snatched the noodles off the stove,
quickly dumping them into the colander in the sink. He didn't need to touch
them to see that the noodles was overcooked. Looking over at the sauce pan. He
didn't want to even imagine the condition of the pot, let alone the sauce,
going by the black smoke that was coming off of it. There wasn't enough to
start over.
 
"sorry pap. looks like i fudged it all up."
 
"IT'S A-ALRIGHT. WE CAN HAVE S-S-SOMETHING ELSE FOR D-DINNER."
 
"yeah..." Sans didn't understand what had happened. He was chopping some
tomatoes one minute and the next the food was completely overcooked.
 
 
 
After reading Papyrus his book, Sans went into his room. He felt like he could
sleep for a month. Maybe he would. He barely made it into his pajamas before
collapsing on his bed. He was asleep before his head hit the pillow.
 
There was no telling how long he was sleeping, but Sans felt like he could use
a few more days inside of the dreamless darkness that was sleep.
 
Sans jerked awake, but he wasn't in his room. He was back in the Lab. Back on
that bed. He couldn't be back here! His father told him that he was done!! He
looked down at his body. It came as no surprise that he was naked, but he
wished that he wasn't. However something was different.
 
His stomach was huge!
 
Like he couldn't really see anything past it. And it was odd that it was
glowing slightly more than normal. Before he could think more about it, the
door to the Lab beeped and opened. His father walked in.
 
"Nice to see that you are awake, Sans. I've already told you several times not
to ********* ********. While it is a little early, ******** *** ***** is the
only thing that I can do now. Has *** ***** caused you any pain since awaking?"
 
Sans' ears was ringing. Some of the words that came out of his father's mouth
was nothing but loud static. "sir?" He tried.
 
"The *****. Ignorance is not cute, Sans." Gaster sighed as he rubbed a hand
over his skull. It was a sure sign that that he was irritated almost to the
point of snapping. He grabbed a clipboard and wrote something on it, before
sitting it back down. "It doesn't matter. The ********** should be working now.
I'll just *** *** ***** ***."
 
The look on his father's face had his soul clench in fear. He had no way of
knowing what was said, but he didn't have to know. The fact that he was back on
this table told him that it was something that he wanted no part in what so
ever. The room was fading around the edges and Sans' feared that he was losing
conscious.
 
'maybe it's better this way. i don't want to know what dad wants to do to me.'
Sans turned his gaze away from the looming skeleton, allowing his body to relax
as much as he could. He couldn't relax at all. His father was going to hurt him
again!! Pain caused him to scream out. He was sure that he was going to die-
 
 
Sans jerked awake when something slammed into him. His soul was trembling and
his head was spinning. The room was too dark to see so he clicked his side lamp
on, nearly knocking it over in the process. It was Papyrus. Papyrus was in the
bed with him, his tiny body was shaking against his side.
 
"papyrus? what's wrong??"
 
"I HAD A B-B-BAD DREAM. I WAS C-COMING TO GET IN THE BED WITH Y-Y-YOU..."
Papyrus took a few breaths to try and calm his panic. "YOU STARTED S-S-
SCREAMING WHEN I-I-I CAME IN YOUR ROOM. I-I-I-" Papyrus' words trailed off into
uncontrollable sobbing, his tiny body shaking even harder.
 
Sans fear quickly slipped into self loathing. Papyrus was already upset from
his nightmare, and all he did was made it worse with his stupid screaming.
 
"i'm sorry papyrus..." He maneuvered the small body so that he could pull the
covers from under him. Sans slowly rocked Papyrus and hummed a soft tune. It
was a while until the crying and shaking stopped. He carefully tucked the small
boy in bed with him. He wanted to promise the sleeping boy that he wouldn't
have another nightmare, but he already knew that wasn't a promise he was going
to be able to keep.
 
Sans had a feeling that this was only the beginning of a fresh new hell for
him.
