Notes
     This is some really heavy subject and I'm sorry if this fanfiction
     troubles you, I'm just experimenting and this is the first time I've
     touch this type of fucked up shit. Again, I'm sorry.
See the end of the work for more notes
Sans looks over his brother with a fond smile. He had just finished sewing
Papyrus's new outfit, or as Papyrus calls it; his new battle body. When Sans
had handed him the clothes, the pure joy in Papyrus's face just warms Sans's
heart. When Papyrus hugged Sans to show his appreciation, Sans loved his warmth
and it made him felt happy for once.. But there's a feeling in his chest. A
sinful feeling that he just wished to ignore. The need to slip down his hand
into Papyrus's.. No. He needs to stop. He doesn't need to taint those innocence
of his.
Thankfully, Papyrus let go of him before even lay a hand on his bones and
distract himself with his new outfit.
He sighed, disappointed and enraged with himself. When did this feeling came
from? Oh, right, his silly crush that evolved into a more serious thing had
affected the way he thinks. He couldn't stop the nasty imaginations running
through his mind but he knew he could hold it in.
He took a deep breath and looked over Papyrus to see if he's done trying out
his outfit. He could feel his breaths became heavier than ever when he sees his
brother in the outfit.
"Wowie, Sans! This is so cool, look at me!!" Papyrus smiled brightly and
twirled around and seeing all the details and works put into it, swaying his
hips side to side and Sand could clearly see his brother's sacrum and pelvis
which led him into trying not to think of it as much as possible and smiled at
his brother, sweating his magic, nervously.
"Y-yeah, bro, it looks really great on you..!" Sans was squirming a little bit
on his seat, trying to not let his magic get out of control as he rubbed his
thighs together. He was obviously trying not to get distracted by staring at
his brother but he couldn't help it, his brother's outfit was too revealing too
ignore.. "P-Papyrus? Could you sit on my lap?" Shit, what did he say? Sans
couldn't believe at what just came out of his mouth and was unspeakable when he
just realized that it would just made his situation worse. Before he even have
the time to stop Papyrus, he looks down only to see Papyrus already sitting on
his lap with those innocent eyesockets. "Haa.." He managed to hold the low moan
back before his brother heard him, damnit, why is his magic is so goddamn
sensitive?!
"Brother? Are you okay?" Papyrus asked and scoot closer on his lap which made
him nearly went crazy with these little touches by Papyrus. He huff in a
response and saw his brother looking at him with a confused face. The pure
expression drove his mind to madness as his magic suddenly reacted out of
control which made him to summoned out a cock by accident, and he's pretty sure
Papyrus could feel it judging by the surprised face he's pulling. "Sans, is
there a pen in your pocket? I know you've always need it for science and stuff
but why can I feel it from here?" Sans didn't know whether to laugh or die.
Well, he did the first one with a nervous laugh and would probably did the
second one in the future.
"Well, that's because i-its not a pen." Sans avoided Papyrus's gaze in shame.
Does he really needs to be selfish and took his brother's innocence for his
sake? Sans wanted too but it just felt wrong, Papyrus was still a babybones,
after all. An 11 years old babybones..
"Not a pen? Then, what is it? It felt.. Really big to be a pen." Papyrus
shifted uncomfortably on his lap, causing his erection wanting more than just
unintentional teasing. "Brother, are you okay? Do you have a fever? You're
really hot right now. Do you want any of my help?" That's it, he will actually
do it, its fucked up but he knows someone out there would reset the timeline
and everything would just be normal to what it was and Papyrus would have no
memories of it.
Sans smiled weakly at his brother and nodded. His brother beamed with
excitement and asked, what is it that he can help. "Well, um, could you just
stand there for a second?" Sans pointed at the empty spot infront of him.
Papyrus nodded and get off Sans's lap and went to the spot Sans's was talking
about, which was just 2 inches away from Sans's seat. "Well, uh-"
"Sans, why is your pants glowing?" His brother asked, innocently.
"Its -ah- something that your magic could make if you really love someone." Or
if you're just lusting over your little brother in a sick twisted manner.
"Ooh, can I make it too?" Sans nodded, hastily. Desperate for his brother's
touch but he needs to be patient. "How?" Sans formed a disgusting smile on his
face.
"Let me help you, come closer, bro." Papyrus came closer to Sans without
hesitation, is he really that eager in helping him? Well, he supposed its for
the good. "Okay.." He let out a sigh and give a quick kiss to Papyrus, which
was only their teeth clashing in together. "You trust me, right?" Papyrus
nodded. Sans let out a chuckle and lightly caressed Papyrus's spine down to his
sacrum and pelvis and watched as his brother was startled by the sudden touch.
The expression on Papyrus's face urged him to continues as he pulled down
Papyrus's pants. He felt the dread in his stomach get bigger but he got over it
and caressed Papyrus's lower half to find a sensitive spot of his.
"Haa.. Brother?" There it is. Sans rubbed his finger on the spot and he could
feel Papyrus squirming above him. Low moans could be heard coming out of
Papyrus's mouth. Sans summoned a tongue and licked the spot multiple time which
caused his brother to let out some lengthy moans. "Ahh.. Brother..? What is
this...?" Sans looks up to see Papyrus had actually conjured up a tongue and a
throat which was a surprise for him but he knew Papyrus was a smart kid for his
age so he just beamed proudly.
"That's a tongue, Papy." He watched as his brother played around with the
orange tongue. "Alright, bro. Could you, um kneel?" Papyrus stopped playing
with his tongue and hesitantly, kneeled infront of him. That's his good little
brother.. Sans thought and spread his legs, making his erection more visible.
He then, open the zip to his pants and freed his hard cock. Papyrus's eyes
widen at how large it is. "Now," he began, "use that tongue of yours, Papy.."
Sans whispered to Papyrus.
Papyrus, unknowingly, obeyed Sans and leaned his head closer to his erection
and licked it a few times just like how Sans licked at that spot that made him
feel good. "That's it, that's it. Now put your mouth on it." Sans whispered,
yet again. It made Papyrus hesitant but he do it nonetheless and wrapped his
mouth around the glowing cock. "Now, go up and down." Papyrus go in a bit
further and then went up just like Sans had told him. "Aah, good, good, now, do
that again and again but faster." Papyrus does it rapidly, again. "Ah, yes,
like that -aahh!" Sans seemed enjoying it so Papyrus continued bobbing on his
cock.
As his brother continued on, he could feel himself reaching into a climax. His
moans was getting a bit louder too. "Good boy, good boy.." Sans managed to
muttered it to Papyrus, as one last final thrust from his brother made him came
in his brother's mouth and face. Blue liquids dripping down on Papyrus's face
to his chin. It took his brother by a surprise when Sans cum shot right at his
face too. Sans let out a sigh of relief. He patted Papyrus's head and give him
a warm smile. "You're a good boy, Papyrus." Papyrus seemed to like the
compliments that Sans had gave him.
"Thanks, Sans! But what is this.. Blue.. Uh." Before Sans could say anything,
Papyrus swallowed the cum that is in his mouth and all that is on his face. "It
tastes.. Weird.." Sans was shocked. He couldn't actually thinks that Papyrus
was going to... Oh shit, he's hard again. "Oh, brother! Your blue stuff is up
again!" Sans was embarrassed and horny at the same time. "Do you want me to
help you, again?" No, no.
"Yeah.."
"Do I do it, again?" Papyrus said and was ready to suck his cock, for the
second time but Sans stops him. "Brother, what's wrong?" He wanted to say that
what they're doing is wrong but instead he said;
"Could you conjure up a butt, bro?"
Papyrus began to think if he knew what a butt was and weirdly, he remembers
Undyne, uh, shaking her butt in the school while she's dancing. "Let me try!"
He then, uses the same technique that Sans had did to him but more rougher, he
don't know why but he wanted more than gentle touches.
Sans watched his brother, nervously, holding back the urge to jerk off to the
sight of his brother touching himself. Then, suddenly an orange ecto body of
Papyrus's lower body started to formed. A a cute small cock and a butt was
formed and Sans could feel himself humping in mid-air by just staring at
Papyrus.
"Sans, I did it!" Papyrus leaped happily which made his cock bounced in sync.
Sans twitched in excitement but also disgust for himself. He really hoped that
someone that controls the timeline actually reset for good.
"Good job, Papyrus!" He didn't know if his enthusiasm was real or not. "Now..
Come here." Before Papyrus could even move, Sans latched onto Papyrus and hold
him still above his crotch, Papyrus was light just like he expected.
"E-eh, brother?" Papyrus looks down and see his brother's hard cock beneath,
nearly touching the ecto-skin of his.
"Papyrus, look at me." Sans pleaded as Papyrus looked at Sans with a worried
expression with a tint of fear in his eyes. Sans hates making his brother fears
him. "Shh, you trust me right?" He could see that Papyrus was hesitant this
time.
"Uhh.. Yes. Yes, brother, I t-trust you." Papyrus said in a small voice. Sans
wanted to hear more of that voice, louder.
"Thank you, Papy. I love you, okay?" Sans gives Papyrus a peck on the forehead.
He could feel Papyrus shaking beneath him and he hated it.
"I love you too, Sans.." Papyrus hoped that it doesn't sound seem that forced,
he really loved his brother but he was also scared of what Sans would do to
him. He trusted Sans, right? Then, why does this feels wro..? No, Sans had
given him so much, its time to repay his brother.
"What I would do would be a little painful at first but it will eventually
feels better. Ready?" Papyrus nodded. That was all Sans needed.
As Sans lowered Papyrus's body, his cock came in contact with Papyrus's hole.
Papyrus hold his breaths in when he felt that Sans was going in. Suddenly, Sans
deepened his cock more which made Papyrus gasped and choked out a sob. It hurts
but he does it for Sans.
"Brother..?" Papyrus's breath was cut short when he felt the whole length of
Sans's cock in him. "S-Sans.. It hurts..." Papyrus cried out.
"Shh, you're strong, you can do it." Was all Sans had said before beginning to
thrusts Papyrus's body into his cock. Papyrus moaned out in mixed pleasure and
pain, tears streaming down his cheekbones. This felt so wrong but there's no
turning back. "You're doing great, sweetheart. I'll keep on going." Sans said
in a soothing voice and thrusts into Papyrus more.
"S-Sans! Stop! I don't like this, anymore!" Papyrus choked out a sob as his
brother thrusts into him a bit harsher when he said that, earning a yelp from
the younger brother.
"I-I can't stop.." Sans gritted his teeth and forces a few more hard thrusts
with anger, not to Papyrus but himself. Papyrus screamed and begged to stop but
he could not hear it, as he reached his climax, again, cumming instantly into
his brother's ecto-part.
Silence was what they met when both of them stops panting. Papyrus quickly get
off Sans's lap and get his clothes off the floor and looked back at Sans, his
body shaking, violently. With one last eye contact with his brother, he left
the room without saying anything.
Leaving Sans drowning in guilt and blame. Why couldn't he stop this in the
first place? Why was he so incompetent at holding back his magic?! He shuts his
eyes tightly as tears started falling from his face. He wanted to go back. HE
WANTED TO GO BACK.
>RESET >CONTINUE
>RESET<
He opened his eyes to find himself in his room, what did..? He looked besides
him and there was.. Papyrus's new outfit?

Flowey was stunned. He was actually disgusted at what he had witnessed. As much
as a goon Papyrus is, he doesn't deserve that, no one does. Manipulated to do
those disgusting things by his brother.. Flowey was enraged. He never hated a
timeline so bad but this one took the cake.
Flowey let out a frustrated scream and stabbed the ground with his bullets.
He's forever holding a grudge on that smiley trashbag.
