I would have linked the Honeymustard collection and Slave AU by Askellie, but Iâm pretty sure youâve already read them. You may have seen some of these before, but I hope I showed you some new, horrible stuff to look at! :P
â â â â â â â â â âÂ
Thank you for the fic rec submission, anon!! Youâre right, a bunch of these are by some of my good friends so Iâve read âem, but there are quite a few that Iâve never even heard of before :O
For anyone interested in some dark fic recs, the anon from a while back came through with this list! As I havenât read all the fics on this list, Iâm unsure what warnings to give for each fic in specific but at a glance, a good chunk of these involve noncon and/or torture so please read the warnings before deciding if itâs the fic for you!
Beyond that, if dark fic is the thing for you, enjoy! Bâ)
I'm so excite you're doing this meme! Can I ask about T, U and V for Underfell Sans and Underfell Paps in general?
Wahhh, Iâm excited too!!! ;w; I actually wrote all this out and lost it so now Iâm rewriting it ;o; I hope itâs a good read for ya, Nil! huehuehue ;3
UF!Sans
T = Toy (Do they own toys? Do they use them? On a partner or themselves?)
Due to aforementioned Bad Brain Stuff, I donât really see UF!Sans as the type to invest any real interest in switching things up for himself. He doesnât care to use anything more than what he has on hand to take care of himself. Post-recovery and relationship however, I think heâd be down to experiment a little. Heâd be good with both using toys on a partner and having them used on him and I think heâd come to really enjoy it quite a bit.
U = Unfair (how much they like to tease)
I headcanon UF!Sans to be a bit of a tease no matter which iteration of him it is, but the degree to which heâs comfortable getting playful with a partner like that varies pretty distinctly from one to another. For example, Sans in AAA would absolutely thrive on being a tease while the one from s&s would enjoy it but not at the same level.
V = Volume (How loud they are, what sounds they make)
The boy is vocal af. Moaning, panting, whining, swearing, dirty talk and beggingâonce he gets really into it, Sans sorta loses himself in the moment. Trying to hold it back results in a lot of shredded pillows and bedding because those teeth are murder on soft objects. âKeep Quietâ kink is a p hot one though, so no oneâs really complaining.
⊠except maybe the neighbours.
UF!Papyrus
T = Toy (Do they own toys? Do they use them? On a partner or themselves?)
UF!Papyrus is an experimenter at heart. Whether or not a version of him ends up really into it, I like to think he at least tries most things just to see if it really pings him or not. So yes for sure to owning toys and using them on himself or a partner would depends from fic to fic. :3
U = Unfair (how much they like to tease)
An unintentional teaser. Papyrus likes to really pick his partner apart and thoroughly please them (going through all the steps in his Advanced Dating Manual ofc) so that slow, steady pace can really work people up without him really knowing that itâs happening. Of course, once he knows, he can go either way on extending it or having mercy depending on who it is and how heâs feeling Bâ)
V = Volume (How loud they are, what sounds they make)

âI've got one more I want to do.â
The monster got up and slid off the bed. He walked toward the wall.
âCome over here.â
Sans hopped off the bed and started to follow, but got an uneasy feeling he couldn't explain to himself as the other monster leaned back against the wall. Sans' arousal was inexplicably dissipating into nothing, being replaced by a quiet anxiety.
The monster put on a show of making a decision. It spoke quietly, barely above a whisper, but Sans heard every word.
âI wonder how dirty you really are?â
And when Sans caught the look in the monster's eye, somehow he knew.
âHow about you call me...â
âNo. Don't. Don't you dare, don't you fucking dareââ
âBoss.â
A perfect copy of Papyrus stood in the shadows.
Sans stumbled backwards. The Papyrus copy didn't follow. It stood regally upright against the wall. Sans fell to the floor and scooted himself further away with rapidly kicking feet.
âCome here, Sans.â
Sans froze. Something about the phrase had been drilled very effectively into him. But Onion's training lost an internal battle against deep revulsion. Sans stayed where he was, and the Papyrus copy did too. That look it was giving himâit was psyching him out, wanted to break his spirit by getting him to come to him on his ownâ
Or maybe not. Sans caught the flash of a lens in the corner above the monster. Did it know the camera was there? Was it against the wall on purpose? Did it know it happened to be in the best blind spot in the room? That couldn't be a coincidence, could it?
But why would it...unless it was doing something it wasn't supposed to. Muffet had let Sans endure a number of horrors already without stepping in once, but maybe this was finally something she wouldn't allow. If she knew it was happening.
Sans remembered the monster in the monitoring room, toggling the sound of the different displays. Had they heard the monster use Papyrus' voice, or had they missed it? Was he speaking too softly? They needed to get the visual.
Sans just had to stay over here in the middle of the room, where nothing could hide from the cameras, and wait. Either the monster would be drawn out and his game would be up, or he would give up and do something less utterly despicable. Sans looked at the door.
A shadow fell over him.
âThatâs not going to do you any good, dear brother.â
Sans felt a cold wash of horror flood through him as a firm hand came down to grip at his shoulder, phalanges disturbingly familiar in their weight. Fear froze him in place, unable to even move his head to turn back around to look at the monster wearing his brotherâs face. He heard a chuckle from behind him and he was struck by an image from what seemed like ages ago, watching movies with Papyrus on their couch, passing comments that made his brother groan in frustration, reveling in the sense of accomplishment when one finally, finally , won him a startled laughâ
âPlease,â he croaked, and the monster shifted into view in front of him, crouching down till he was at eye-level. Sans immediately looked down, body starting to tremble even just at the sight of polished red boots, âPlease. P-please donât. I c-canât. I canât .â
The monster was in full view of the camera now but there was no sign of Muffet or any guards. Was she on her way? Would she stop this? Or had the monster standing in the blind spot just been a coincidence? He certainly seemed unconcerned right now, center stage and in full view.
Sans risked another glance up at the camera.
âSans, stop that.â The copy scolded lightly and the tone was so perfectly Papyrus that Sans could feel the automatic apology forming at his teeth. But there was the edge of something teasing in it, an undertone heâd never heard his brother use before, and that was just enough to hold the words back. He continued to stare up at the camera, desperately hoping that, of all things, Muffet would at least spare him this .
A sigh.
The monster shifted forward and scooped Sans up into his arms.
âNo,â Sans gasped and started to kick, the instinctive need to escape rushing in as the monster pulled him up close to his chest, âNo, no, noâdonâtâI wonâtâMuffet wonât let you!â
He tried fiercely not to think too close about the practiced feel of being in his arms, tried not to compare it to the hazy, drunken memories of being carried upstairs to his room on nights when heâd come back loose-limbed and swaying from Grillbyâs. Or worse still, of being carried after the encounter on rotten egg street, clinging to his brother for safety and protection after the slug hadâ
He kicked harder, wanting more than anything to put as much distance between the two of them that he could. Unfortunately, his continued struggling only prompted the monster to grip onto him tighter, gloved claws biting into him and making Sans wince. He still refused to look at the copyâcouldnât meet his gaze head on when he knew what heâd be seeing.
âI think youâre forgetting who I am.â Sans shook his head. He wasnât the Boss. He wasnât Papyrus. He wasnât . âMy position in the Royal Guard gives me the benefit of holding power over a lot of weaker monsters, Sans. Getting a few guards to turn a blind eye isnât that difficult a task.â
The monster tossed him down onto the bed and Sans bounced lightly on it once before quickly scrambling up and instinctively reaching for his magic. A sick lurching in his soul reminded him that it was still well out of reach, the tracker still embedded deep within his core. A swell of panic overwhelmed him at the thought and his fingers shook even as he clumsily pushed a hand into his ribcage to reach for his soul. Heâd have to pull it out, heâd have to dig in and rip it out of himself and, if he couldnât, heâd just crush his soul within his own palm because it would still be better than thisâ anything would be better than thisâ
Two hands wrapped tightly onto his wrists, wrenching them immediately away from his ribcage. The shock of it made Sans gasp aloud, phalanges twitching still in the phantom search for his soul. A frigid chill coursed through him as the shapeshifter slowly crawled closer towards him, the black of Papyrusâs copied outfit more vivid than it had any right to be as it filled up Sansâ field of view.
âYou ought to be more careful, brother. You could get hurt like that.â
âFuck you,â Sans snarled, yanking at his captured wrists and twisting in the sheets. Heâd rip his arms out of his sockets if it meant a chance at getting away. He wouldnât let this happen. He wouldnât . Heâd die if it came down to it but he wouldnât let this monster use his brotherâs face and debase him like this.
â Sans .â The monster sighed and the admonishment in his voice was so nostalgic that Sansâ soul skipped a beat at the sound.
He was going to be sick.
âG-get off me! Get off of me, you fucker!â He spat, pushing back the nausea and gathering all the vile resentment building inside him into a heated struggle, âYouâre not him! Fuck you, youâre notââ
He was silenced by the press of a wet kiss to his mouth, a tongue slipping easily in between his parted teeth. He was too shocked to do anything but freeze stiffly as the monster licked into him, fingers prying into the space between his jaws to keep him from biting down. His soul churned uncomfortably but fear kept him locked in place.
The Papyrus copy pulled back and Sans truly looked up at him at last, head feeling heavy and body shaking. Sharp cheekbones, scarred socket, pointed teeth; not a single feature out of place. A face as mock-angry and long-suffering as Sans remembered it, despite the smug expression currently adorning it. Everything down to the slightly crooked ridge of Papyrusâs nasal boneâit had healed wrong. Papyrus had broken it when they were just kids. His brother had fallen flat on his face while chasing after Sans in anger over some prank or another. Sans remembered laughingâwas absolutely identical.
He felt the tears spring to his sockets, âYou canâtây-you canât do this to me.â
It was as if the fight had been drained out of him, his emotions leaving him weak and trembling and completely out of sorts. The monster climbed over him, pushing him softly into the mattress. Sans couldnât find it in himself to offer even token resistance. Tears continued to drip steadily down his face as the shapeshifter pinned his wrists down to either side of his head, boxing Sans in underneath him.
Papyrusâs scarf dangled over his face, tickled where it brushed against him.
Sans shuddered.
âS-stop. Please. Youâyou can be anyone. Anyone . J-justâjust not him . Please, I⊠I-Iâll do a-anything. â
âHmm, thatâs quite a thing to say.â It was almost a relief to hear the monsterâs natural voice spring from between Papyrusâs teeth, all reedy and high-pitched, âI had a back-up option in mind but⊠can you really be sure that youâll like that any better?â
He couldnât.
There was no form the monster could possibly take that Sans would â like â any better. He could only ever hate it a little less. But, between being raped by someone he knew and talked to from time to time and being raped by his brother â
⊠Sans would take what he could get.
The monster leaned further down over him, let the tongue uncurl from Papyrusâs mouth and licked a long, wet stripe along the side of his neck where the hood of his jacket didnât obstruct it. The monster stayed there for a moment, grazing his brotherâs teeth against the notches of his vertebrae teasingly. The full-bodied shudder of revulsion that followed only made the monster chuckle again, forcing Sans to bite back a noise of distress at how its voice had switched back into Papyrusâs familiar cadence.
âI suppose it doesnât matter,â the shifter said as it pulled back up again, âSince Iâm enjoying your reactions far too much to consider changing in the first place.â
Sans felt his soul sink deep, a black void of horror enveloping it entirely, âNo, no, no. No, please, Iââ
âShhh,â the monster soothed, a red-gloved hand coming up to stroke his face.
At the contact, tears sprang afresh in his sockets. The monster huffed out a breathy laugh at the sight of them. It drew out its conjured tongue once more and Sans squeezed his sockets shut, not wanting to see the red glow come any closer. His tears spilled over at the action and the shifter drank them up, leaving crawling sensations in his bones in the wake of its attention.
It brushed a hand down towards the hem of his shirt, lifting just enough to expose his spine.
Sans felt like he was choking on his pleas and his own rising nausea. But the monster ignored him, happy to indulge in its continued exploration of his body. Its hand slid underneath the ratty, red t-shirt he wore, reaching for his spine. Papyrusâs copied fingers curved into the dips between each vertebra as they travelled teasingly up and down. Try as he might, Sans couldnât distract himself from the feeling, each caress wrenching another wretched sob from him till he was shaking and begging for mercy with every breath.
Despite the fact that he was still mostly dressed, he felt completely stripped naked. What good were an old shirt and a tattered jacket when his pelvis was bare and he was pinned to a mattress, waiting to be fucked? He was powerless; no magic to speak of and no way to escape this living nightmare. Even if he attempted to fight further, itâd be pointless. With his luck, the monster would likely hold him down and take him anyway; wouldnât even dust him afterwards to spare him the horrors.
Still, as the monster used Papyrusâs hands to stroke at the crests of his hips, Sans couldnât stop the instinctive fear that gripped him and screamed at him to act.
He lashed out with a rough kick, the retaliation unexpected enough to actually catch the monster solidly in the chest, â NoâŠ! No, no, no! G-god, fuck , Iââ
But the struggle was short-livedâPapyrusâs armour didnât leave room for any lasting physical damage and, once the surprise wore off, the monster grabbed onto his flailing legs with ease.
â Enough ,â the shifter growled, Papyrusâs eyes narrowing at him as it twisted the offending leg sideways.
Sans yelped at the pain that shot up through the bone and felt his HP slide down incrementally. Its grip tightened further, enough that Sans could hear the leather of Papyrusâs gloves creak and his own bones start to groan in protest. Sans didnât want to obey, but the sudden burst of energy had been ripped right out of him with one brutal wrench of his leg. Instead, his body continued trembling, hiccoughing sobs escaping him at the slightest movement from the monster above him.
The monster continued to keep him trapped, one hand pressed firmly to his chest to keep him down while the other felt around at his side. If Sans still had it in him to be anything other than mind numbingly terrified, he mightâve been curious as to see what it was doing. As it was, the stern gaze periodically peering down at him from Papyrusâs face kept his limbs too locked up to react. So, when the monster wearing his brotherâs body finally found what it was looking for and turned back towards him, Sans could do nothing but stare in horror at the glinting silver spoon in its hand.
âOpen wide, dear brother.â
This was really happening.
âI promise youâll feel much more relaxed after this.â
This was really happening.
The monster brought the spoonful of pudding up to his mouth.
Sans screamed .
âNO! NO! FUCK YOU! LET ME GO YOU FUCKING FREAK!â
It was one thing to be forced to endure this torture and another thing entirely to be forced to enjoy it. To make him want itâto make him complicit in this abominationâ
No.
No .
As Sans began to struggle, the monster let the full weight of Papyrusâs body drop down onto him to keep him restrained. It easily pinned both his wrists back with one of Papyrusâs much larger hands and, with the other, calmly inched the spoon towards his mouth. All Sans could do was strain his head back as far as he could away from the drug.
Maybe if he was loud enough, someone would hear him and know something was wrong.
âI HOPE YOU BURN! â
Maybe Muffet would be pass by and wonder just why her tuna was suddenly so active that he was yelling loud enough to bring the walls down around him.
âI HOPE IâM AROUND TO SPIT IN YOUR DUST! FUCK YOU! FUCK YOU! â
Maybe, maybeâ
The monster let go off his wrists and slapped him, sharp and firm, across the face.
The shock of it made him cry out, pain spreading like a pulse from the point of impact even as his HP took another dip. The shapeshifter used his moment of disorientation to push the spoon into his mouth and spill its contents onto his tongue. Quicker than Sans could react, it recaptured his wrists with one hand and clamped the other over his mouth to keep him from spitting the drug out.
Sans struggled against the hold but the monster held on tight, challenging every angry buck from Sans with a calm, impenetrable stoniness. Desperate, Sans tried to smear as much of the pudding as he could onto the glove sealed over his mouth but, already, he could feel it start to dissolve on his tongue. Panic was settling into him, along with a creeping warmth suffusing into his bones.
He could feel the tears spring back to his eyes.
The Papyrus copy grinned at the sight of it, âYou owe me this, brother.â
Sans tried to focus on the words instead of the way his magic was starting to strain against his restraint in an effort to form, âW-what⊠what a-are youâŠ?â
âJust think about it,â Not-Papyrus said, letting his eyes drink in the sight of Sansâ body going flushed underneath him, his efforts not enough to keep the drug from doing its job, âDo you have any idea how much of my time Iâve spent chasing after you? Over and over again, no matter how many times you got kidnapped on a whim?â
It wasnât Papyrus saying thisâ it wasnât him. But.
The words stung all the same.
Sans knew it was trueâheâd regretted the fact enough on his own by nowâbut, for the shifter to bring it up with such confidence⊠like he really was PapyrusâŠ
Sans had to shake the thought away.
He reminded himself with a bitter pang that it was public knowledge what a nuisance he was to his brother. The fact that the shifter knew about it and brought it up shouldnât surprise him as much as it did. Not when he had even the subtle twitches of Papyrusâs face down to an eerily uncomfortable science.
Still, there was something to be said for a monster that knew someone elseâs weak points so intimately. He wanted to cower, to hide away. He couldnât look the monster in the eyeâtoo afraid to see disappointment in his brotherâs face.
A hard shiver ran through Sansâ body, the pudding slowly taking full effect. Yet again he wished the drug did more than just shoot up his arousal, wished it would at least dull his other feelings in return so he wouldnât be pent-up from so many disorienting mixes of emotions. Heâd rather feel nothing at all than both want to be fucked and hate every minute of it.
In this case, it mightâve been best if the pudding just knocked him out completely.
The monster didnât react to his bodyâs shaking save for giving Sans a stern frown that seemed plucked straight from his memories of Papyrusâs lectures, âDo you have any idea how much money Iâve spent on rescuing you? And from situations you couldâve easily avoided?â
He had some idea.
The guilt was overwhelming.
Papyrus deserved better. Papyrus deserved the best things this shitty world had to offer.
Sans was not one of those things.
Not-Papyrus shifted his weight back at last, even deigning to let go of Sansâ wrists, but Sans made no attempt at retaliation with his newfound freedom. He couldnât. Not now when the pudding had made his cunt form in a surge of magical arousal, already slick and wet and ready. It was all he could do to keep his legs together, hot tears spilling down over his face as the monster pretending to be his brother took a long, lingering look over his form.
It was gross.
It was nauseating.
He didnât want to see the way Papyrusâs sockets half-lidded with lust. Didnât want to see his baby brotherâs gaze focused on his exposed pelvis with a hunger heâd never seen in them before. Like it was taking everything he had not to fuck Sans right then and there.
He hated it.
He hated it even more that, when the shifter lifted up his shirt this time and brushed Papyrusâs hands against his ribs, his body tingled with welcome anticipation.
He shouldâve had the whole cup.
Maybe that way he wouldâve overdosed into sweet, blissful oblivion.
The Papyrus copy moved in, pressed his brotherâs mouth to the side of his skull as he hissed, âWith the amount of gold Iâve sunk into your well-being, I should be able to have you whenever I like.â
The words felt like ice water being poured into his soul.
Papyrus wouldnât say that, he reminded himself.
Papyrus wouldnât say that .
But it didnât make a difference what Papyrus would and would not say when the monster wearing his face was scorching the words into Sansâ mind for an eternity.
âD-donât do this.â He was back to begging, desperate and fearful, âPlease d-donât⊠please donât do this to me.â
âWhat are you talking about, Sans?â Not-Papyrus said with a sigh.
Even that was just like his brother. The sigh, the frown, the scrunch of his browbone, the inflection of his wordsâ âWhat are you talking about, Sans? Of course I know what Iâm doing!ââevery part was exactly as Papyrus wouldâve said it. He could only wonder how long the shifter had watched his brother to perfect its imitation.
A sick, roiling feeling ripped through him at the knowledge that heâd likely learn more about his brother now than heâd ever wanted.
âW-why would you⊠why would⊠w-why do this?â
âSans,â the Papyrus impersonation scolded, looking pointedly at the slick gathered at his pussy, âDonât pretend that you donât want this when youâre so wet already.â
You did this to me, you bastard , he wished he could shout, I donât want this. I could never want this.
But all he could manage was a pathetic whimper, blubbering and teary.
The copy gave him a weary look before patting the side of his femurs as if to console him. Sans desired nothing more than to back away from the touch. Not that the shifter noticed or cared about his revulsion as it slowly changed from patting at his legs to smoothly stroking both his femurs easily up and down.
âYou look good like this, brother,â the monster continued, murmuring lowly, âAll dripping and eager for me.â
The words made him instinctively recoil, body shuddering, âD-donât⊠donât touch me. Donât t-touch me.â
The copy ignored him, instead moving to peel off the gloves from his brotherâs hands. âTell me the truth, Sans. How long have you wanted me to fuck you?â
The sickening lurch the words provoked in him kept Sans from speaking.
It didnât matterâthe monster went on, unhindered by his silence, âIs that why you kept getting kidnapped?â
With the gloves folded and placed carefully to the side, the monster rubbed the bare bones of Papyrusâs hands against Sansâ thighs, all the way up to his hips. Sans shivered at the touch, his internal disgust battling against the shot of arousal the pudding forced through his system. Papyrusâs hands travelled further up still, toying with the zipper of Sansâ jacket before reaching up and pulling at it by the shoulders. The fur of his hood tickled against his face as the monster adjusted it till he could easily snake it off of him.
Once off, that too was meticulously folded and set down, neat and orderly, as the monster imitated his brother.
âWere you waiting for someone to put you in your place? To fuck you like a whore till you were gagged and filled with cum?â
He continued speaking but Sans didnât say a word. He couldnât, grinding down his teeth the way he was to keep from making any sound at all; to keep from vomiting at the imagery every sentence sparked in his mindâs eye. It was difficult, not in the least because the copy had both Papyrusâs hands underneath his shirt now, stroking lightly along his ribs, playful and teasing. It was unnerving to feel bone against bone like that, hands that werenât his own touching him in a way that even heâd never bothered to.
âWere you hoping Iâd get mad enough to do it myself?â Not-Papyrus rumbled the words with dangerous promise, hands scraping roughly back down along Sansâ spine, sharp points catching in the notches along his body and making him hiss.
Still, Sans didnât answer him.
Maybe if he just lay there like the tuna he was advertised as, the shifter would get bored with him and leave.
âWell.â The hands retreated and it was only the clink of a belt being undone that let Sans know where theyâd gone, âYou certainly got what you wanted, didnât you brother?â
He looked up and felt his soul nearly stop dead in his chest.
The monster had worked open Papyrusâs pants and was now lightly thumbing at the head of his erection.
It shouldnât have been surprisingâheâd expected as much, after allâbut, somehow, actually seeing it was different from having guessed at what would happen. If heâd had the presence of mind, he mightâve noted the length of it or the thickness or the way the magical construct was just a shade slightly darker than his own red. As it was, all he could comprehend was that it was actually happening; that this freak of a client was going to put that inside of him.
That it was going to fuck him with his brotherâs cock.
âN-no. No⊠no, oh g-god, no,â Sans scrambled backwards, bunching up the sheets under his feet as he pushed at the mattress in an effort to get away, âF-fuck, donât. Donât t-touch me, d-donât come near me!â
Papyrusâs mouth only curved up into a smile, bemused.
The monster stalked forwards, stroking leisurely at Papyrusâs dick. Sansâ back hit the headboard. There was nowhere for him to go. He darted his gaze around, searching for an escape while still stuck in a confused loop of angry curses and desperate pleas. None of them mattered. The shifter continued towards him, reaching out with Papyrusâs unoccupied hand to grab at his ankle.
With a firm tug, he pulled Sans down onto his back again. Even as he shouted and squirmed and tried to push away, the shifter grabbed onto each of his femurs tightly, spreading his legs wide and putting his dripping cunt on full display. It lined them up so that the head of Papyrusâs cock was just the barest inch away from him.
âS-stop! Stop, stop, d-donâtâ!â
Sans choked on his words as the monster slammed into him.
â Ohh ,â the copy moaned with Papyrusâs voice, and Sans didnât think heâd ever be able to unhear just the way it sounded, echoing as it was around the inside of his skull, â Fuck , thatâs good.â
It was big. Even with the pudding making him wet, it stretched him almost to the point of pain. Sans tried to focus on that; tried to focus on the ache of his walls instead of the fact that he was being filled up withâ
Donât think about it.
Do not think about it.
Still, the tears formed at his sockets.
Still, it felt like his soul was being crushed with the weight of what was happening.
âDo you feel that, brother?â the copy whispered, reverent and low and with the familiar familial address that just made Sans flinch all the harder, âDo you feel how tight your pussy is around my cock? Itâs like you were made for me.â
The monster slowly pulled part-way out of him, the space Papyrusâs cock left making him feel sickeningly empty. It paused for a moment before rushing back in, just as hard as the first time and somehow even deeper. Sans could feel it sting inside him. The imposter repeated the motion. Again and again and again till it sped into proper thrusting and Sans felt his brotherâs erection throb within the confines of his cunt.
The horror of it seemed to crash down on him all at once.
Sans let out a broken wail of despair.
âG-god, no⊠s-sto⊠p⊠s-stop, I ca⊠nât take it⊠I canât t-take any⊠more, ple-easeâŠâ
âShh,â Not-Papyrusâbecause that was the one point he desperately needed to latch onto to keep him sane; that this was not his brother, not Papyrus , because slipping into any other thought for even a moment would destroy himâsoothed, rubbing a careful hand along the top of his ilium in a manner gentler than Sans could ever remember his brother being with him, âWas I too fast for you, Sans? I suppose, in my haste, I forgot to consider how delicate you are.â
The shifter pulled out and Sans felt his pussy clench, bereft of the girth of Papyrusâs dick.
âJust let the Great Papyrus assist you with this, brother.â
Sans was going to throw up.
The monster rubbed the full length of Papyrusâs cock against the folds of his cunt, the wetness allowing him to slip easily back and forth. Sans tensed at the teasing, gripping tight onto the bedsheets even as the tears continued to stream down his face. The copy dragged his cock upwards till it pressed against his clit. He circled the head around it, building a rising intensity with each grazing pass over the nub of magic. Then, the monster let the weight of the erection lay there for a moment against it and Sansâ felt his cunt throb in anticipation. With a chuckle, the monster pressed a thumb down against the head of Papyrusâs cock and let the phalange slide down to stroke at Sansâs clit, smearing it with pre-come.
âAhh⊠ah, ahnâŠâ Sans couldnât hold it back anymore. The drug in his system made every touch burn in the most pleasant way, made him want and need and desperate to come. It wasnât enough to take his fear or his repulsion away, but it was more than plenty for overcoming his urge to stay silent.
âEnjoying yourself?â the shifter asked, Papyrusâs voice playful and sultry.
There was only one answer to that and Sans gave it in the form of another choked off cry.
âItâs okay to like it, brother.â
It wasnât.
It definitely, absolutely, was not .
And Sans hated that he did.
The monster shifted a little, held Sans more firmly as it re-positioned Papyrusâs cock at his cunt. Sans braced himself but the copy only dipped in shallowly with the head. Slowly, carefully, it repeated the motion, dipping in and out of his folds. It lingered in a few of the pseudo-thrusts, swirling the head around the inside edges of his pussy, rubbing firmly against the walls. Sans shivered every time, the action only making the tension inside him go tighter and tighter.
It changed tactics again, pulling out and rubbing the dampened head against the outside of his pussy once before circling it back towards his clit. There the monster began to rub, firm and with purpose, using Sansâ own slick gathered onto Papyrusâs cock to ease the way as it dragged the full length of the erection against his small bundle of magic.
âO-ohh⊠mnn, a-ah⊠hahâŠâ
He was starting to pant and drool, eyelights threatening to roll up into the back of his skull.
âThatâs right, Sans. Let me hear you.â
His body was going tense, locking up all rigid.
âAh-ah⊠hahh⊠nn âŠâ
âYouâre close, arenât you?â the monster said, and without waiting for an answer, it increased the pace, shifting Papyrusâs hips up at the same time to better the angle. It rocked against Sans, rubbing and pressing the magic around and over his clit again and again till it hit the perfect amount of pressure at just the right place.
The sensation of release ran through him.
Automatically, the feeling prompted Sans to announce himself like heâd been taught to. âIâm⊠I-Iâm gonnaâIâm coâ uuhming! â
Long, tapered phalanges stroked him through his release, keeping the aftershocks going till he felt well and truly sated. But as the haze of orgasm disappeared, so did the numbness of his mind. He was dimly aware of something being whispered to him, low and encouraging, but he couldnât hear it over the deafening buzz of his own utter humiliation and disgust.
He came.
A client took his little brotherâs form and rubbed Sans off with an imitation of his dick
and
he
came .
Sans let himself go motionless, still and silent as he stared up at the ceiling.
He really was the worst.
âNow itâs my turn,â came the copyâs voice of his brother and still Sans couldnât find it in himself to move or to say a single thing.
âSince Iâve done so much for you already, youâll have to do a little something for me.â The shifter leaned fully over his body then, dipped down just far enough to press a chaste kiss to the front of his mouth, nuzzling against him afterwards in a way Papyrus hadnât done since they were kids, âCall me âBossâ, Sans.â
He wouldnât.
He wouldnât say or do anything at all.
Let the monster have him. How much worse could this get?
âBrother, are you listening?â
Itâs not like he could hate himself any more than he already did.
â Sans .â The imposter was starting to sound impatient, voice reminiscent of the tone Papyrus took on every morning he tried to wake Sans up.
If only he could curl up and go to sleep right now.
Maybe, if he was lucky, heâd never wake up again.
âCall me âBossâ or this is going in your mouth next.â It commanded, timbre hard and unforgiving, as if that would make a difference.
What did it matter? Either way he was already filthy.
Either way heâd never be able to look his brother in the face again.
â Do it, Sans. â
But suddenly, the voice was all wrong.
It had gone back to being high-pitched.
Sans cautiously looked up at the unforeseen switch to see Papyrusâs face looking grim and foreboding. âDo it. Or Iâll tell your brother you begged me to turn into him.â
Sans froze.
He stared at the shifter, soul kicking up into a frantic pace in light of his panic, leaving all his bitter apathy aside.
âYou⊠you canât do that.â
âAre you so sure about that?â A cruel, creeping smile spread wide across Papyrusâs face, âYou know what? Better yet, Iâll tell him the truth . Iâll tell him that you came just from me grinding his dick against your dirty little pussy.â
Sans felt dizzy, like all the feelings heâd been desperately suppressing were hitting him all at once. âHow would⊠he⊠h-heâd never believe you.â
âWith a brother that constantly disappoints him like you do, Iâm sure this wouldnât be too much of a stretch. And if heâs a little difficult to convince then, well,â A laugh, and suddenly Sans was hearing his own voice speaking aloud to him, âI could always work my magic and let you do the talking, if you catch my drift.â
Sans hadnât thought it was possible for him to feel any lower than he already did.
Heâd been wrong.
He scrambled up to his knees, resisted the urge to lay himself out prostrate as he begged, âNoâŠ! N-no, please, donâtâdonât tell him. Please donât tell him, I-I⊠Iâll do w-whatever you say.â
There was a lengthy pause where the monster considered him.
Sans felt every second pass like the worst imaginable sort of torture.
âGood,â the copy finally said, letting its voice change back into Papyrusâs low growl, âNow go on and call me âBossâ.â
Sans didnât feel any better for having convinced him. âO-okay, Boss.â
âBeg me to fuck you.â
âP-please fuck me.â
ââBossâ.â
Sans swallowed down his nausea. â⊠BossâŠâ
âDo not toy with me, Sans,â the Papyrus copy demanded, voice laced with warning, â Say the whole thing. â
â⊠please⊠f-fuhâŠâ He couldnât stop the tears flowing down his face, couldnât stop the way his voice trembled and shook with shame as he spoke, â⊠p-please fuck m-me⊠BossâŠâ
âThatâs better.â
The copy grabbed him by the shoulders and laid him back down. This time around, he didnât wait even a moment before tossing Sansâ legs up over his shoulders and getting himself ready. He stroked himself back up to full hardness, rubbed his length tentatively against the lips of Sansâ pussy making him flinch, still sensitive from his orgasm.
âI want you to be vocal. I want you to end every fucking sentence with âBossâ if it comes down to it.â Papyrusâs face swam in his vision through his tears, but Sans nodded along mutely anyways, âIf you donât follow through, a certain skeleton in Snowdin is going to learn some very interesting things about his trashbag of a brother. Am I clear, Sans?â
âY-yes⊠Boss.â
âThatâs good, brother.â
Without any further preamble, Papyrus pushed into him, full and thick and filling him up to the brim. His fear made him tense, made him clench around the cock inside of him. The feeling only made his assailant moan aloud.
âDoes that feel good?â he grunted as he tightened his grip on Sansâ legs.
âY⊠yeah⊠B-boss,â Sans managed to force out, feeling his chest go tight like his body couldnât restrain the feelings he buried in between his ribs.
Papyrus thrusted into him harder. âI bet you used to touch yourself while thinking about me. I bet you would fuck yourself on your fingers and wish it was my cock instead. I bet that you wished that I was there to fill you up with my cum.â
God god god heâd agreed to do this.
He was scum, he was dirt, he was the lowest of the low.
âY-yeah, Boss.â
âI bet youâd let me fuck you in front of everyone and stake my claim.â Papyrus picked up the pace, his movements faster and faster with each push till Sans felt constantly full, filled up entirely to his deepest, âYouâd just lie back and take it like a whore, wouldnât you, Sans?â
âI⊠I-I⊠would⊠B-boss.â
âMmm, thatâs good, Sans,â he praised and, despite himself, Sans shivered at the genuine praise spilling out from between his brotherâs teeth, âDonât hold back.â
Papyrus continued rutting against him and the motions went from uncomfortable to something a lot more pleasant. Sans could feel his body start to prepare once more, slicking the way even further as it readied to take another orgasm. His pussy gripped tight around the cock inside of him, hugging it in a way that made every thrust feel that much harder. He could hear Papyrus groaning above him, panting and cursing under his breath.
âAh-ah-hahh⊠nn!â Sans moaned at the friction, every upward motion hitting him just right.
His brother leaned further over him and Sans squeezed his eyes shut, not wanting to see his face any nearer. His action was followed by low laughter as Papyrus continued to fuck into him and Sans felt his face grow hot with embarrassment. His brother was close to coming now, he could tell by the way his hips were starting to stutter in their rhythm.
Just a little more and itâd finally, finally be over.
A hand stroked his face softly. âI love you, brother.â
Sans eyes shot open.
âI⊠w-whâŠâ The tears starting spilling over his cheekbones in earnest, âN-no. No. H-how could yâŠâ
The thrusting sped up, making him sob all the harder. â Nnn , thatâs it. Come on.â
âStoâŠp⊠stop, stop⊠n-no more⊠no more, p-please.â
âAhh, fuck , thatâs so good, brother,â Papyrus panted, and Sans could feel his cock throbbing with the need to release, âYouâre clenching around me, Sans. Ask me to let you come. Remember what youâre doing this for.â
Sans choked back another desperate wail for mercy, tried to force himself to use the words he needed to instead, âI-I want⊠I w-want toâŠâ
Die. I want to die.
I want to die I want to die I want to die die die .
âWhat do you want, Sans?â Papyrus prompted him again, relentlessly rutting against him now, his hips smacking up against Sans till the sounds of it filled the room. Sans felt the tension in his body ramp up once more, his soul twisting in a sickening way.
âP-please,â he whimpered, not sure what he was begging for at this point.
âSay it.â
âL-let me come.â
ââBoss.ââ
â⊠B-bossâŠâ
â Sans .â His tone was not negotiable.
The pressure was building inside of him, rising higher and higher. It pressed against every single one of his bones, torturous in its intensity.
Papyrus rammed into him hard enough to make him scream, more tears springing up in his sockets from the strain. â Say it. â
âAhh⊠ahn, I⊠letâŠâ He couldnât hold it back anymore. Not with the way he could feel every thrust so deep inside him, rubbing against his walls. He couldnât take it, âL-let me c-come, b⊠let me come, B-boss⊠p-please.â
âYou may.â Papyrus smirked.
And with a few more well-aimed thrusts, Sans felt the tension in his body finally snap and he turned his head to the side
and
threw up.
Sans was hardly aware of the rocking against his hips dying down to a stop.
He had a hand thrown over his midsection, clenching weakly at his shirt as excess magic expelled from within him. With every heave, he felt more and more light-headed but he couldnât stop until there was no more left to give. He made piteous groans as his body emptied itself, hacking and coughing when it finally seemed at an end.
He felt weak.
He couldnât even lift a hand to clean off the bits of vomit still clinging to the sides of his mouth. Â
âWell. Thatâs a bummer.â The voice was all wrong again and Sans shakily turned back to face the monster, noting that it had pulled out of him though it was evidently still hard, âI donât think your brotherâs the type to be into that.â
Sans was quiet, staring at the monster with more clarity than heâd had since the start of all this.
âBut thatâs alright,â it continued brightly, âI did have one other choice. And I think itâs plausible that he might take an, uh⊠shall we say, âscientific interestâ in this sort of thing.â
Right before his eyes, the monster shifted till Sans was looking at a very familiar dark coat and a face he hadnât seen in ages. He felt cold all over. Bones rattling at the sight.
Gaster gave him a crooked grin. âWould you say that youâre a bit of a daddyâs boy, Sans?â
âGet off the bed and stand up, please.â
Muffet. Muffet was here. Sansâ head snapped up. She was flanked by two large guards. The client had gotten off the bed and was standing next to it. Muffet looked at Sans and for the first time since Sans had met her, there was something like true remorse in her eyes.
She didnât say a word, instead nodding at the guards who walked up and grabbed the client under each arm. Sans could hear it break out into protests but Muffet didnât even look its way as the guards dragged it forcibly from the room. Instead, she watched Sans quietly. Once it was just the two of them in the room, she sat down carefully beside him on the bed.
âSweetieâŠâ She started, and instinctively flinched at the pity laced in her words.
Sans hated Muffet. He hated her.
He wanted to shout. He wanted to scream. He wanted to fucking hit something because this was all her fucking fault .
But.
He was just so, so, tired .
So, when Muffet wrapped her many spindly arms around him and began stroking at his back, Sans simply leaned into her and started to cry.
   He wasnât taking any visitors but the human found him anyway.
It wasnât like it was hardâhe hadnât left the dark confines of his room in days. Muffet had monsters checking in on him around the clock, concerned that he would try to hurt himself, especially since heâd been skipping multiple meals. Sans wanted to laugh at her.
If he knew how to kill himself with all the safeguards she had in place, heâd have done it already.
As it was, all he could do was lay in bed and think about how disgusting he felt.
âSansâŠ?â the child called out to him.
He didnât respond.
He wanted them gone.
He wanted everything that reminded him that there was a world outside this room to stay out and never come back.
He wished that they would all just leave him alone.
Leave him alone to sleep and sleep till he never woke up again.
Frisk moved up closer to him. âWas it⊠was it really bad this time?â
No way he could tell a kid about something like that, even if heâd felt inclined to in the first place.
Besides, what would he even say? That heâd gotten fucked by a monster wearing his brotherâs body? That every time he closed his eyes, all he could see was the look on Papyrusâs face as he slammed into his cunt? That all he could hear were the sounds of his groans? That no matter how many times Woshua cleaned him, he could still feel his brotherâs cock penetrating him through the wetness of his cunt?
No.
A child had no business being exposed to that.
The human put a careful hand on his arm before quickly drawing it back, as if afraid to frighten him, âItâs not⊠good for you to stay all alone like this. You should go out and talk to your friends. Leave your room and eat something a-and⊠take care of yourself.â
He didnât bother responding to tell them just how incredibly unappealing all of that sounded.
âI thinkâŠâ Frisk hesitated, and although Sans wasnât looking at them, he could imagine the exact look of reluctance on their face, âI really think you should tell your brother, Sans.â
That was the absolute last thing he would ever do.
He wasnât telling anyone that, least of all his brother.
If the world had any mercy in it at all, Sans would never see Papyrus again.
He would quietly fade from his brotherâs life and things would be better for it.
âHe⊠he wants to help.â
No one could help.
Unless they were willing to dust him, no one could do anything.
âHe cares about you. You know that, right?â
He shouldnât.
He wouldnât ânot if he found out about this.
âSansâŠâ The human sounded desperate, âSans, Papyrus loves you.â
Like a dam breaking inside of him, Sans laughed.
Sans laughed and laughed and laughed till his body was shaking and Frisk was taking several steps back away from him. He could see them tremble and it only made him laugh harder, pain racking up along his ribs and lancing through his soul. Their mouth was moving, they were trying to speak to him, but he couldnât hear anything over the sound of his own rancorous laughter.
He laughed and laughed till he was screaming and sobbing and thrashing in bed.
By the time Muffet came in with guards to hold him down, the human was already gone.
 <<<<<<<<<<
 He wasnât taking any visitors but the human found him anyway.

As it was, all he could do was lay in bed and think about how disgusting he felt.
âTell me what you need and Iâll fix it, Sans.â
The determined way they said it ripped a bitter laugh from the haze of his apathy, âNo one can fix this, kid.â
âWhat happenedââ They seemed to think better of what they were asking, âWhat⊠what wouldâve made it better?â
âNothing,â Sans spat, and his voice came hoarse from disuse and stale anger, âNothing wouldâve made it better. The fucker had a friend in the guards. The only thing that even stopped it this time was that Muffet finally saw what was happening and came in to put an endââ
Frisk wrapped their arms tight around him.
Sans was shocked into silence, arms dangling uselessly at his sides as the child hugged him close.
âLeave it to me.â They whispered, full of promise.
 <<<<<<<<<<
 One hand clamped over Sansâ mouth and pegged his head against the wall. Another hand held up a cup of the drug. The monster tipped it into Sansâ eye socket. Sans screamed into the hand and thrashed his limbs. But by the time the monster let him go, he could feel the substance making its sluggish journey inside him.
Sans curled into a ball.
âOh god. Oh my god. Oh my god.â
The monster pet Sansâ back.
âThereâs no need to be so difficult. Youâre going to enjoy it, of course.â
My position on topping/bottoming is literally âeveryone is always a switchâ lmfaooo I know I tend towards uf!sans being submissive but thatâs just cuz I like seeing my fave get wrecked hahahhh,,,, otherwise, Iâm literally down for anything tbh, so donât worry anon--I got u Bâ)
(also, lowkey dedicating this to @morelikeskelesinstwopointoh because I havenât been able to get this line from their fic out of my head since I read it hhhhhhhhh so this drabble was def influenced by that Bâ) <3 tho the bros are in a much healthier relationship in this lmfao the dynamic is totally different)
Pairing: Fellcest
Words: ~1700
Warnings: Definitely nsfw, light bondage, dirty talk, blowjobs??, face-fucking??, idk man itâs somewhere in between the two tbh, letâs just generalize it as âoral sexâ lmfao, also Sans is taking charge here so if thatâs not your thing you might wanna skip this over,,
âOpen up, Papy.â He teases, dragging the head of his cock along the sharp, serrated edges of his brotherâs teeth.
Papyrus glowers at him, flushing a deep, humiliated red from his bound position on the floor between Sans spread legs. His femurs are tied to his fibulae to keep him kneeling and his arms are fixed firmly behind his back. Sans would have gagged him too---usually does when they do this---but today requires more thorough use of his brotherâs mouth.
Besides, by now Papyrus knows when to keep quiet anyway.
Sans strokes the side of his brotherâs face, admires the sight of his self-confident sibling trussed up below him. He ruts himself lightly against Papyrusâs clenched teeth, hissing when the pointed tips catch at him and leave pinpricks of pain in their wake. He smirks when Papyrus snarls at the motion and jerks away from his touch.
âAww, donât be that way, Boss,â Sans grins, hooking his thumbs firmly into the spaces behind his brotherâs tightened jaw, âOpen up for me, yeah?â
Papyrus refuses, grunting as he strains to keep his mouth shut and staring defiantly up at him. Sans feels hot heat pulse through his bones at that expression on his brotherâs face, grips in deeper with him thumbs at the sight of it. His claws arenât as sharp as Papyrusâs---he doesnât maintain them like he should---but theyâre still pointed enough to drag a wince from his brotherâs perpetually angry face.
âYou gonna let me do this?â He lets his voice drop into a low growl, just barely hanging at the edge of a threat, âOr are you gonna be difficult, Pap?â
He rubs his length, hard and leaking, dangerously close to Papyrusâs scarred eyesocket, circling around the rim of it. Pre-come smears against his brotherâs face, wet and glistening where it clings to his bones. Itâs a clear warning and his brother doesnât miss it, shuddering reflexively as Sans continues to move lazily against him.
After a momentâs hesitation, Papyrus relaxes his jaw. Itâs enough for Sans to gently pry it open and bring the tip of his cock up to. He brushes a hand softly over the back of Papyrusâs skull as he presses into his mouth. His brother averts his gaze, cheekbones burning brightly.
âYou alright?â Sans asks, the tenderness in his tone is momentary but especially important when his normally headstrong brother gets like this; quiet and pliant under his touch.
Papyrus answers with a flick of his gaze up to meet with his, lets his tongue manifest against the weight of Sansâ cock in his mouth. Sans groans at the feel of it filling in around him, hot and wet and giving under the pressure of his dick. He slowly buries himself further, keeping hold of his brotherâs face from either side, grip loose and relaxed. Â
âAhhh, so fuckinâ good,â Sans praises, brushing his thumb along Papyrusâs cheekbone even as his brother starts to get that antsy, self-conscious look on his face that he always seems to whenever he gets down on his knees for him, âInch that mouth open a little wider for me, Pap.â
At first it seems as if his brother will refuse, eyelights darting up at him, fierce and imperious. Papyrus doesnât say a word though so Sans doesnât pay it much mind, already used to the internal struggle his brother engages in whenever heâs the one to submit. Itâs something that happens even on nights like tonight, when Papyrus is the one to suggest it in the first place.
With some measure of reluctance, his brother stretches open a little further and Sans smiles, shifting his hips up and sliding further into the warm, wet heat of his mouth. Papyrus makes a bitten back noise as Sans presses up to the hilt, filling him entirely. He can see the way his brotherâs eyelights go hazy for a moment, soft and vulnerable in a way that they only get when heâs like this.
âYou look perfect like this, Pap,â Sans whispers, dragging partway out of his mouth before slowly pushing back in, relishing in the slow drag of friction against his brotherâs tongue, âSo fuckinâ perfect with your mouth full of my cock.â
He follows his words with a few shallow thrusts and Papyrus relaxes into a moan, the vibration of the sound rocking up through his body from where theyâre connected. Sans shivers at the sensation, pushes a little quicker in and out of Papyrus as his brother shifts around in his bound position. He keeps watch closely, notices it immediately when the tension starts to ebb out of Papyrusâs body. Itâs not long before he lets himself go lax in Sansâ grip. Papyrusâs sockets flicker shut and he goes still and compliant.
Sans pulls out.
âHaahh---â Papyrus gives an open-mouthed enhale, âS-sans, what---?â
The dazed, confused look on Papyrusâs face is ridiculously appealing, especially with his mouth still parted like that, saliva and pre-come dribbling down his chin. His sockets are still partially lidded, posture slumped and defenseless. His brother is completely open to him when heâs like this, unguarded and entirely exposed.
Sans loves it.
He tightens his grip on the sides of his brotherâs face, digs in so hard that even his blunt claws leave scrapes along the expanse of bone, âI wanna fuck you up, Papyrus.â
His brotherâs sockets widen fractionally at that, and Sans doesnât miss the way his body quivers at the words. Papyrus stares up at him, the heat of his magic still colouring his face hotly. Sans wants to run his tongue along it, wants to taste every bit of bone his brother has to offer, wants to feel the coarseness of his body and his scars catch against his flesh.
... but maybe some other time.
Today itâs about what Papyrus wants.
His brother lifts his chin just slightly, lets his jaw fall slack. Papyrus doesnât speak, but Sans can see the message in the heaviness of his gaze as he strains against his bonds.
âThen do it already.â
Sans grins.
He slams back into his brotherâs mouth without preamble, taking satisfaction in the way Papyrus half-gasps in surprise when he does. Sans doesnât wait for him to adjust before pulling back and bucking right back in again, his cock thick and full against his brotherâs tongue. Papyrus groans at the feeling making Sans shiver appreciatively at the reverberation.
âFuck, Boss,â Sans pants, rocking his hips back and forth, âDidnât know you were such a little whore.â
Papyrus squeezes his sockets shut with another barely restrained moan.
âYou gave in so easily.â
He punctuates with a quick thrust and Papyrus breathes in shakily around him.
âGuess you must really love choking on my dick, huh?â
He gives Papyrus only a fraction of a second to register his words before he slams back into him. His brother makes a strangled noise of protest, spine arcing outwards as he bends in reflex. Sans slowly pushes all the way in, watching as tears start to gather in the corners of Papyrusâs sockets, before stopping there. His dick pulses in the tight, wet heat of his brotherâs mouth and Sans grips himself at the base to keep from coming.
Papyrus weakly strains against him but, as he struggles to pull away, Sans grabs onto the back of his skull with both hands and keeps him there, firm and unrelenting. He can feel the way his brotherâs conjured throat clenches desperately around him and he groans and bucks into it even as Papyrus chokes. Sans presses his brotherâs skull further onto him till heâs grinding the head of his cock against the walls of Papyrusâs magic and the tears are spilling over onto his brotherâs face.
Itâs when he feels Papyrusâs body start to go limp against him that he finally pulls out and his brother gasps aloud, broken and ragged and wet.
Papyrus hunches over, pulling in frayed breaths one after the other. The slick in his mouth drools over the edges of his parted teeth, tears mixing in as they fall down off his face. Sans watches for a moment before moving forward. He cups Papyrusâs skull in his hands and thumbs away the tears that continue to gather at his sockets.
He leans in close, âNext time, Iâll make you beg for me like the slut you are.â
Papyrus trembles in his hold and Sans pressed a soft kiss to the top of his skull before pulling away again. Sans grabs himself in hand and strokes roughly without any regard to finesse. It doesnât take much before heâs coming, painting wet smears of fluid onto his brotherâs face.
He continues to strokes himself through his climax, keeping careful watch of the way his brotherâs eyelights have gone cloudy with arousal, gaze unfocused. When heâs done, he reaches forwards and drags his fingers through the cum on Papyrusâs face, letting it collect on his phalanges before he brings his hand down to his brotherâs own neglected erection. He wraps a tight fist around him, slicking him up with his release before tugging at him, quick and practiced.
Papyrus comes with a hiss pressed out between clenched teeth.
Sans smiles and kisses him again, this time to the side of his face. Then he reaches around to undo the leather straps holding his arms together and follows with the same for the ties around his legs. As soon as heâs released, Papyrus starts rubbing at where the binds have left light bruising on his bones.
âReally Sans? Do you seriously have to finish on my face every single time?â Papyrus says even as he inspects himself, voice patchy and rough, âFucking disgusting.â
Restraints all undone, Sans settles in against his brother side, leaning into him with a satisfied sigh, âItâs not like it ever stops you from coming.â
âItâs still gross.â
âMmnn,â Sans snuggles up close to him, wrapping his arms around his brotherâs middle, âGuess next time Iâll have to come down your throat.â
