****** The Food Chain ******
by Nerdytrashcan
Summary
     Sans is a really smart kid, in a school full of juvenile delinquents
     and criminals. All he wants to do is get out of his situation by
     graduating with good grades, but when the biggest asshole in the
     school shows up with more than perverted intentions, will Sans fight
     his way out of his current situation, or will he submit?
Notes
     This is a gift for bela-sins on tumblr, formerly known as nasty-
     bones, who had their blog taken down, and had to start from scratch.
     They are the creator of Underclass, a high-school AU, where Sans and
     Papyrus are unrelated, Sans is a nerd and Papyrus is a jock.
     Underclass is quite loving... Eh heh heh... Kinda messed that bit up.
     Anyway, appreciate constructive criticism, and go check out bela-
     sins, their art is quite good (bela-sins.tumblr.com), and while
     you're at it, I appreciate re-blogs
     (nerdytrashcanfanfiction.tumblr.com). Feedback is much easier to take
     on my tumblr, since I am on it more often, just message me. I hope
     you enjoy my indulgence, sinners. ;)
***** Chapter 1 *****
“Fuck, fuck, fuck…” was Sans’ internal monologue. The Maths exam was next
period and Sans’ cheat sheet was only on draft 4. A small skeleton with his
torn red t-shirt tucked semi-nicely into his ragged trousers squatted in the
center of a small closet, the only place where he could study in peace.
Everywhere else was either broken, filled with douches or filled with drugged
or boozed up kids. Sans lived in an extremely poor neighborhood, broken down
houses and litter plagued his street, and he shared his closet with 3 used
condoms, a 4 smashed bottles of cheap beer, a lot of rat droppings and a dead
bird, but it was quiet. Sans’ was the top of his class, even if that wasn’t
saying much. He was quite intelligent however, and he wanted out of this shit-
hole, he wanted to go on to enjoy his life beyond being a bum from a town of
bums. He wanted to go to university and become a computer scientist. All of
these dreams, all of these aspirations, and he was born into this slum, where
the norm was to earn your money by robbing gas stations and cars, and using
that money to buy cheap liquor. “I can’t fail, I can’t fail, I can’t…” ‘THUD!’.
Sans recognized that sound as a door being slammed open, although the volume
meant it could have easily been smashed off of it’s hinges. The smell of vodka
was immediately overpowering. Sans nearly screamed as he turned sharply towards
the entrance. A taller skeleton stood there, wearing a black leather jacket
covering a red shirt, with black jeans with switch-blade in hand, compared to
tucked in shirt and pants, he was quite normal. Papyrus was the leader of 'The
Guard’, a group of hooligans and under-age criminals. As degenerate as
Underground High was, there was one rule. 'Don’t fuck with The Guards, and
especially don’t fuck with Papyrus.’ Teachers were scared of him, the rest of
the staff bought drugs from him, all of the students wanted to be him, all
students except Sans. Sans hated him. Sans hated most people at this school
with a passion, although he thought of Papyrus as the worst of them all, he was
scum, criminal scum. 'Draft four will have to do… Shit.’ Sans panicked
internally, slipping his cheat sheet into his bag. Papyrus’ snicker was all
Sans needed to put him on high alert. Papyrus was drunk as shit, and caused
pure misery on his good days. “Lookie’ wat’ weev’ gat’ ere’ 'hic’.” Papyrus
slurred. Sans hated Papyrus, but he wasn’t stupid, he pulled out his money he
had intended to use to buy some food, but Papyrus would probably want it, plus
Sans didn’t really enjoy stale bread and cheese. “'hic’ Yoo’ got tha’ monee’
nerddd’?” Sans handed over the 1 dollar and 50 cents, along with the small
piece of candy he found on the pavement. Sans was remaining quiet with the
exception of slight grumbles. “'hic’ Thatz’ et’? Ya’ got anythong’ elz’?”
Papyrus scowled, waving his switch-blade as he popped the peppermint out of the
wrapper and into his mouth. “N-n-no… But you know I’m good right?” Sans
responded. Sans didn’t owe him anything, unlike most other kids who owed him or
some other member of The Guard drug money, but Papyrus was greedy, and much
bigger than him… And had a knife. “No I, 'hic’ dant’ you azhowl’.”  Papyrus
slurred once more, bringing the sharp edge of the knife up to Sans’ cervical
vertebrae, the cold edge of the blade causing tears to well up in Sans’ eyes.
“Please… Pap-papyrus… Don’t do this, please…” Sans muttered, sobbing. The force
of Papyrus’s hand pressed against his chest was overpowering, but it started to
lessen as Papyrus’ scowl formed a smirk. “'hic’ Nyeh-heh… Fine.” Papyrus
started, causing Sans to stop crying. He may be out of the frying pan, but
Sans’ was quite positive he was about to plunge head first into the fire. “I
stal’ went sumthen’ fram’ yoo’ thoh’.” Papyrus concluded, his sharp fangs
glistening from the dangling light. Sans’ knew that was coming. “Anything…”
Sans choked up, still worried. Without warning Papyrus  threw his body against
Sans,causing Sans to yelp in terror. Sans had  felt a cool breeze on his legs
as he realised that papyrus had ripped them clean off. Sans’ didn’t have any
underwear on, he couldn’t afford it. “'hic’ Nu’ underwar’. Wat’ u’ slut’.”
Papyrus snickered. That line caused Sans’ to go into shock and violently thrash
against Papyrus, but Papyrus was much stronger, and kept Sans pinned to the
wall. “Kummon’ 'hic’, youu’ hore’. Uwl’ fickon’ cut you.” Sans’ stopped
resisting, the threat of early death terrified Sans’ into submission. Papyrus’
tongue lolled out of his mouth and trailed up Sans’ neck causing him to wince,
the taste of salty tears  was candy to Papyrus. “Hew aboot’ we git’ thes’ shuw’
on da’ road whure’?” Sans did NOT appreciate being labelled as a whore,
especially by Papyrus. Papyrus threw his hand down to Sans’ pelvis and gripped,
causing Sans to sob harder. Papyrus’ hand went from sadistically squeezing to
caressing tenderly. Papyrus was grunting like an animal as he was trying
desperately to spawn Sans’ magic. Sans was scared, very scared, but the
grunting and the touching, it was driving Sans crazy. Sans was trying to fight
arousal like a crazed beast. He never thought this would happen to him, but he
was moaning like a girl from being violated by the the person who he considered
to be one of the biggest examples of evil. “PaAAH-pyruss. PleaAHH!” Sans cried
into Papyrus’ jacket. “Nyoh’. Hous’ eh’ good sloot’.” “Fuck, fuck, fuck.”
 “'hic’ Oeykay’.” Sans regretted that comment as he felt a strange sensation,
magic growing in his pelvis.
***** Chapter 2 *****
Sans had always been a bit weird, but he never expected this. He didn't expect
that he would be being molested by Papyrus of all people. He had plenty of
people he could fuck at a moments notice, simply because they wanted to stay on
his good side. Furthermore, Papyrus was gay? Sans had never seen him fuck any
girls, but it was widely spread that he did. Maybe he liked both, who knew. It
doesn't change much about his current situation, Papyrus was set on fucking him
right here, right now. Sans was doing everything he could to suppress his
magic, he didn't want to give Papyrus the satisfaction. Shame it wasn't
working. Non-biological monsters are hermaphrodites, and with their sexual
organs being magic, can form either gender they choose. Even still, when a non-
bio goes on heat, they go on either a male, or female heat, with the need to
mate being confined in one gender. Sans' was used to having female heats and
arousals, but NEVER, did he act on them. Apparently, he was going to get his
urges sated right now, despite what he would like. Sans felt soft magical
tissue starting to form in his pelvis, and Papyrus was taking full advantage of
this, Papyrus was pinching the lips of his now forming cunt, quite painfully.
He felt like he was being ripped apart from the groin up. “Eh heh. 'hic' Yuure'
lovin' thes'.” Papyrus purred. There was a strange softness in his voice, but
he could tell that the tone wasn't out of any sort of softness on Papyrus'
behalf. Papyrus' fingers pushed deeper into Sans' cunt, pinching deeper inside
him. This kept going until Papyrus had pushed his finger knuckle deep, scraping
against Sans' dry magic. Papyrus' fingers were cold, being as he was a
skeleton, it didn't surprise Sans' he was the same, but it didn't help. Along
with that, the pinching was unbearable at this point. Sans was screaming in
pain, praying for anyone to come and save him, but nobody would dare to go
against Papyrus. “AHHHH! PAHHHHPYRUSSS!” Sans cried out in pain. Finally,
Papyrus pulled his fingers apart, and retracted them from Sans' pussy, making
Sans feel like his slit was being shredded by sandpaper. Sans' mind, now blank,
was rejoicing at the rough bone being removed, but it was quickly replaced.
Papyrus had moved his head down to Sans' hole, and was licking at it like a cat
would drink milk, rapid and shallow. The sensation was new to Sans, sure he had
touched himself before, but never on a female heat. It made him feel icky, as
he would consider himself straight, and the time he touched himself while on a
female heat, his thoughts drifted to a different cuisine of monster. While it
was only natural of course, Sans identified as male, and it just felt wrong. So
he stopped doing it. Yet the tongue lapping at his pussy made it feel tingly,
as if the tongue was too shallow and he should want it deeper, but he didn't
want it deeper, he wanted it out. Papyrus hadn't removed his switch-blade, his
long arms from his lanky physique helped keep it to Sans' throat. Papyrus'
strokes with his tongue became longer, and deeper, causing Sans to let out
gasps, as if he wanted it. These gasps only egged Papyrus on, as he stretched
his magical tongue just that last extra hit to contact Sans' sweet spot,
earning Sans' first moan. Papyrus didn't stop there. Longer. Deeper. It was
driving Sans crazy. He hated it, but it just made him feel complete. Longer.
Deeper. Sans felt a pressure beginning to build in his pussy, it was completely
foreign to Sans. Longer. Deeper. Sans shouldn't have liked this, but the
pressure. It was completely different to the way Sans usually felt after
stimulation. Sans was sure the fingers were back, but they didn't feel like
sandpaper, they felt perfect. Faster. Deeper. The pressure was ready to
release. Faster. Deeper. Here it comes. Sans was screaming in a mix of hate and
bliss. Slowing. Swallowing. This wasn't right, the pressure should be
releasing. Slow. Shallow. No. Still. Out. “You stopped...” Sans uttered through
sobs. Papyrus pulled the blade from Sans' throat and opened the door. Hours had
passed and Sans was sure Papyrus had sobered up a bit, which makes Sans think
he was sick of it. “WAIT!” Sans felt himself scream. Papyrus grinned and turned
back to Sans “'hic' Yeah, you want more?” Papyrus sneered. Sans didn't want to
nod, but he did. “Nyeh heh 'hic' heh. Beg for it.” Papyrus whispered. “I... I
want you to finish.” “Try harder.”” Papyrus growled. “Please, Papyrus. I want
you to finish me off, I want you to make me cum.” Sans begged, bewildered by
what was coming out of his mouth. “Harder...” Papyrus finished. Sans couldn't
think straight. “PLEASE PAPYRUS I WANT YOU TO FUCK ME! I WANT YOU TO MAKE ME
CUM LIKE THE BITCH WHORE I AM!” Papyrus smiled a wide, sinister smile and shut
the door, returning his head to Sans' slit, and began diving his tongue in and
out and hard and fast as he could. It didn't take long for Sans to feel himself
go over the edge and come. Crashing waves hit him in the back, and he felt
himself being knocked into the sea. The sea was warm, and colours exploded
around him. He had never felt like such a complete girl... Girl..? Sans snapped
back to reality as the orgasm faded. “Pahh.. Pahhpy...” Sans' panted. “'hi'
Good girl.” Papyrus chuckled before Sans felt his satisfied cunt fill back up
again. Sans had finished, but Papyrus had not, Sans felt like this was Papyrus'
plan. “AGGRH! That really hurts! Why couldn't you do it before!?!” Sans cried.
“Because 'hic', you wouldn't have called yourself 'hic' a 'bitch whore', and
that 'hic' part is crucial.” Why did Papyrus need his consent if he was going
to rape him anyway. “ARGHH!” Papyrus moaned as he shot into Sans, filling him
up. Sans was beginning to black out from the stimulation. Everything was
whirling around him, but Sans swore the last thing he felt before falling
unconscious, was something clicking around his neck.
