CONTENT WARNINGS (spoilers): kink negotiation, roleplay, safe word usage, consensual nonconsent, watersports, dirty talk
Sans had probably let this go too far. It didn't feel right to call his heat an excuse for his behavior, not when he'd spent plenty of heats in solitude before. Now every time he started getting even a little warm, he prevailed on his brother to treat him to a quickie, even if Papyrus was on his way out the door to patrol duty.
Now, though, it was even worse, because he was thinking of asking for more than that. Their play the first time had stuck in Sans's mind in such a way that he found himself thinking about it in the wee hours of the morning when he'd kicked the covers off himself from overheating, thinking about it when he was washing up in the shower and let his fingers sneak down to his pelvis, and maybe worst of all, thinking about it while looking right at his brother when they were in a room together. Papyrus warning Sans that he was going to 'punish' him played over and over in the masturbation material reel inside his head.
Sans still couldn't quite believe he'd reached a point in his life where he thought things like that about Papyrus of all monsters. He'd always thought Papyrus was attractive, but in a sort of appreciative way, objective. This week called into question all the times Sans had enjoyed Papyrus touching him with a stray hand, every time he'd been pleased to do what Papyrus told him to do. It rewrote his whole family history in a filthy way that Sans was half intrigued by and half mournful about.
He was so messed up, wanting to get Papyrus involved in this. To keep doing it. And yet, some part of him wanted to find a way to frame this so it wasn't a bad thing, that this was something they were both allowed, for entirely selfish reasons. He wanted to not think about how it was wrong and just enjoy himself.
And there was no denying that with the level of trust already between them, it brought up so many more possibilities for sex that, if Sans were completely honest with himself, he wouldn’t have trusted anyone else to do with him.
“Hey Boss, have you ever thought about, like...role plays and shit?”
His brother froze in place where he was showing Sans his system for organizing socks by colour and size, “...why are you asking?”
“Um,” Sans squirmed, already feeling the wetness of heat coming back. They hadn’t had sex for almost twelve hours, and that was apparently long enough. “I was kinda...starting to heat up again, and I guess I was just...thinking about it...” Sans had actually started to get used to casually mentioning the progress of his heat cycle to his brother, an idea that would have mortified him before. But what had he expected, Papyrus to make fun? His brother was always almost exceptionally appropriate, and this turned out to be no different.
Papyrus straightened up, slowly placing his socks back into his drawer before reaching out towards another drawer and pulling it open. He rifled around inside of it for a moment and pulled out a small red leather-bound book. He spun on his heel back towards Sans and took a seat next to him where he sat on Papyrus’s bed.
“As a matter of fact,” he started, flipping the book open to reveal dozens of handwritten pages, “I’ve made...notes about many concepts that interested me.”
“Oh my god, Boss.”
“It’s important to be prepared!”
“No, I just, I mean. It’s impressive.”
“Of course it is. I’ve noticed that many of these ideas require careful forethought and planning in order to maximize their potential.” Papyrus went on, only the barest hint of colour to his cheekbones from Sans’s praise betraying his otherwise perfect calm. “There’s a few in here that I think you might like...did you have anything in mind specifically, though?”
Sans leaned over to look.
“A few I might like, huh...?” Sans shifted so he was awkwardly cross-legged, suddenly worried he’d mark up Papyrus’s bed. “I guess I was thinking, like...burglar, or...some kinda...like someone sneaking in and...” Sans’s face was starting to feel like the surface of the sun, and he wasn’t sure it was all just from his heat.
His brother didn’t seem to need him to clarify any further, however. With what little Sans had said, Papyrus was already flicking through pages until he stopped and pointed at one in particular, the title big and bold. “Home Intruder with Rich Backstory. This is an excellent choice. I’ve already done nearly all the required research for it.”
The page his brother pointed at was packed full of notes and, what looked like possible diagrams and illustrations? There were quick doodles with descriptive paragraphs beside them detailing exactly what the scenes were meant to portray. And. One part in specific seemed like...character notes?
“What kinda research exactly, bro?” Sans didn’t know there was anything that could be researched about making up a sex fantasy.
“Well, if you want it to be believable you have to really get into the lives of the characters that’ll be involved. I suppose it’d be simpler on your part since you’d be playing...you. But, beyond character guides, there’s notes on activities to try out and things to avoid and just general notes on safewords and—” Papyrus stopped. He flipped the book closed, one finger still inside like a bookmark, before turning to face Sans. “We don’t have one.”
“Have...?”
“A safeword, Sans.” Papyrus frowned, expression going tense. “We haven’t really discussed any sort of boundaries at all.”
“Oh...but it’s not like you ever go too far, and I mean, if I didn’t want something I could just say no...” Sans stopped, more fully appreciating that Papyrus really did know what a ‘home intruder’ scenario implied. “Unless I...didn’t mean it when I said it...oh...”
“My apologies, brother. I should have laid out the ground rules even before our first encounter. I suppose I was...distracted. Though, of course, that’s no excuse.”
Sans pat his brother on the arm.
“Jeez Boss, I’m fine, don’t worry about it.”
“Even so...we should discuss it now if we’re planning on engaging in more complicated scenarios.” Papyrus placed the book to the side, shifting in place so he had his whole body turned towards Sans, giving him his full attention. “Do you have any hard limits I should know about? Things that you absolutely would not enjoy no matter what the context?”
“Oh.” Sans had never actually had to think about it. What kinds of things might come up if they did this? That was just like the Boss, to know all the details about something and be truly prepared. “I guess I’m...not actually crazy about the idea of getting, like, beat up? Or choked for real,” Sans tugged at the spiked choker around his neck, half of his teeth showing in a sideways grin. “...despite appearances.”
Papyrus nodded. “I will make a note of it. And if there are any new limits you discover, either while thinking them over on your own time or even during the middle of a scene, you should let me know immediately. Though I suppose in order to inform me during, we will need to establish our safeword.”
“Right...” What exactly were the criteria? Were there right and wrong safewords? “Did you have any, uh, written in that book too?”
“I did think of several...some likely a little too ridiculous for practical use. In the end, I thought simple might be best and went with ‘blue’ for ‘stop’ and ‘orange’ for ‘go’. We can diversify them further if we need to do so in the future. Unless you had ideas of your own?”
“Heh. Boss. You know you shouldn’t tempt me to put words in your mouth, unless you want the safeword to be Fartmaster.”
“Ugh.” Papyrus rolled his eyelights, though there was a hint of a smile on his face. “Fine then. If there are no objections, we’ll use my suggestion.”
His brother got up off of the bed, picking up his book as he went. He walked over to his closet, pulling the door open and bending slightly to reach around inside. Papyrus retrieved a box after a moment, shutting the closet door once he had it out and then placing it on the floor. He reopened his book and, presumably, flipped back to the appropriate page.
“I believe I already have most of the required equipment, but I’ll give it another look just to make sure...” He glanced up at Sans. “How soon would you like to do this?”
“Equip—?” Sans cut himself off from his shock. Whatever adventure Papyrus had planned out in this much detail, presumably with his usual extra enthusiasm, Sans kind of wanted to be surprised. “Would...tonight...work?”
Papyrus leveled a look at him that was positively predatory, smirk curling up on his face. “Tonight would be just fine.”
***
Sans waited in the kitchen, with his back turned to the entryway. They’d talked about Papyrus sneaking up on him, but Sans wasn’t able to hold still for the time it took to wait, and ended up goofily shuffling along the kitchen cabinets so that his back was perpetually to the entrance.
It wasn’t obvious whether it was his anticipation that made him so attuned to the moment his brother stepped into the room or whether Papyrus had decided to forgo the sneaking entirely, but the sound of his footsteps as he crossed their tiled floor seemed to reverberate loudly as he approached. His boots thudded with every step, sending vibrating jolts up Sans’s spine the nearer he got. But even so, it felt sudden and unforeseen when Sans was pulled back, an arm around his waist and a bone construct at his throat.
“Well, what do we have here?”
Sans felt tingles of excitement from the tips of his fingers down to his groin. The boss was already so into it. And he was...convincing. Sans opened and closed his mouth without reply, not quite having to fake the nerves that paralyzed him at the feigned threat.
“Dangerous thing, leaving your door unlocked like that…” Papyrus’s voice was low and rough already, breath hot against the side of his skull. He tightened his grip on Sans, squeezing around him almost tight enough to be painful. His hand with the attack pressed the slightest bit closer. “For most, that’d be a death wish...but...”
His brother’s hand around his waist trailed downwards, edging at the waistband of his shorts. “I think I like the look of you.”
Sans took quick, short breaths, angling his chin higher as the bone construct drew closer. All it had taken was the mere suggestion for his pussy to form between his legs, the smell of his heat already starting to hang in the air. Sans made some kind of small whimper as it formed, too obvious under his shorts.
Sans could feel Papyrus’s chest rumble as he laughed, pressed as close as they were together. “I thought I smelled something interesting. Tell me, is this why you left your door open? Were you hoping someone would take initiative and give you that fuck you’re so desperate for?”
The colour of Sans’s face deepened a few shades, his mouth hanging open just to breathe. It was difficult to hold back admitting that yes, that was precisely the reason, because that didn’t seem like that fit the situation too well. Would it ruin the mood if he gave in too easily? Papyrus’s voice like that, saying those things, was just about impossible to resist.
“I...”
In one forceful motion, his brother spun him around and slammed him back against the counter, the edge of it digging into the back of his spine. The action was jarring but Papyrus wasted no time in refocusing Sans’s attention. He grabbed Sans’s wrists into one of his hands and pinned them back against the high cabinets while using his free hand to redirect his line of sight, holding Sans’s face still by his chin. Sans was left staring up at his brother, the familiar sharpness of his features shrouded by the sudden dissonance of his new persona...and...
The moustache.
“Pfft.” Sans did his best to maintain a straight face, but the sound still left his mouth.
Papyrus narrowed his sockets at him. “What exactly about this situation is humorous to you?”
“Nothing. You’re a surprisingly handsome home invader.”
He could visibly see his brother’s cheekbones redden at that, but Papyrus’s expression didn’t change. He pressed harder where his hand held Sans’s, scraping them against the wood. “Well, aren’t you lucky then. Getting fucked by someone entirely out of your league.”
“Ow,” Sans squirmed in the rough hold. At first he’d been reacting to the pain, but that comment deserved it more. It wasn’t like Papyrus had to rub that in.
There must’ve been something in his expression because Papyrus’s grip faltered, slackening just the slightest, “...too much?”
He looked concerned, and a hint embarrassed as well. His demeanor had entirely switched from what it was just a moment ago. Somehow, it made the moustache on his face look even more out of place.
“Uh...” Sans was grateful he hadn’t had to break out the safeword for something like that. He looked away. “I mean, you’re not...wrong...” He wiggled his fingers. “But maybe the, uh, slamming me around kinda hurts...”
Papyrus let Sans go entirely, his hand coming down to rest on Sans’s shoulder instead. Then he frowned. “You do know that anything I say in character does not apply to how I really feel, correct?”
Sans shut his mouth and looked down at the floor, feeling even more foolish for letting the words get to him.
There was a momentary pause as his brother waited for him to respond. Seeing that Sans wasn’t about to, however, Papyrus placed both his hands lightly at Sans’s humeri before leaning down and pressing a soft kiss to his face. “I will be more careful with what I say. And, with how I handle you.”
“Th...thanks, Boss.”
As Papyrus drew back again, there was a considering look in his eye. “Did you want to rest for a bit?”
“What? No, no, I don’t need-” Sans tried for a light laugh, but it probably sounded nervous. “I’m not that bad, come on.”
“It’s... it’s not about being ‘that bad’, Sans.” Papyrus searched Sans’s face, worry plain in his expression. “This is about trusting each other. I need you to trust that I would never do anything that you didn’t genuinely want.” He reached back out to hold one of Sans’s hands in his own, rubbing a thumb against where he’d gripped too tight around his wrist. “And... I need to be able to trust that you’ll tell me when I overstep my boundaries. No matter how small you may think it is. That’s what our safeword is for.”
Sans hadn’t really thought about it as something that went both ways. But Papyrus didn’t actually want to hurt him, they were doing this for fun, so the idea of letting his brother do things he didn’t want just to save his own pride...really was pretty stupid.
“Okay, Boss. Sorry. I’ll, uh, I’ll use it if I don’t like stuff.”
His brother nodded, still stroking his wrist. “So, tell me honestly. Do you want to stop?”
“Nah, I wanna try again.” The touch to his wrist alone was getting a reaction from Sans, oversensitive from his heat so that even, or maybe especially a gentle touch was amplified. “Besides, I can’t resist you when you’re wearing that.”
Papyrus let a hand drift up to his face, touching the fake hairs with surprising delicacy. It was possible that he had missed the teasing lilt behind those words entirely. He cleared his throat, “Yes. Well. I did put a lot of forethought into this so. I’m glad you appreciate it.”
A lot of forethought...come to think of it, Papyrus hadn’t brought anything else in with him that Sans could see. It couldn’t be that the moustache was the equipment he’d referred to?
This time, when Papyrus touched Sans again, it was with clear purpose. He placed one hand at Sans’s back, pulling him flush against him, while the other wandered up to his face, thumb working into the space of his jaw and parting his mouth. “Now then...shall we get back to it?”
Sans’s pussy gave a twinge of renewed interest at the contact.
“Y...yeah, um. Orange.”
“Good,” Papyrus murmured, his smile going from soft to heated in an instant, “I think I’ve kept you waiting long enough. Your poor pussy must be drenched by now.”
He followed the comment up with a shift of his hips, moving so that Sans’s legs were spread on either side of his leg in between them. Papyrus bent his knee and pressed it into him, just the slightest bit of pressure to drag the fabric over the wetness gathering there. With Sans’s mouth still parted, it was easy for his brother to lean in and slip his tongue into Sans’s mouth, licking into him, wet and warm, while his thumb remained firmly in position to keep Sans from drawing his mouth closed again.
Sans twisted his legs around Papyrus’s knee, only accomplishing more friction. The grinding was making him moan low into his brother’s mouth as he kissed him. He ended up closing his eyes, trying to get himself back into the mindset of the scene. He was in heat. He’d left the door open and got caught by a stranger, and now he was at his mercy. Sans felt an embarrassing squirt of wetness soak into his brother’s knee while he rubbed there.
“I like that enthusiasm,” Papyrus said, pulling back enough to smirk against his mouth, “So, I’ll reward you with a choice. Would you rather I bend you over and fuck you on the countertop or would you rather be spread out on the floor?”
“Bend me over,” Sans pleaded automatically, only a second later snapping his mouth shut in embarrassment. Playing along with not wanting this was more difficult than he’d really put in for.
“Didn’t even need to think about it, hmm? Not even a bit of hesitation.” Papyrus smoothed over Sans’s slip-up, bringing it back into the scene. He flipped Sans back around, pushing him face forward onto the counter, taking care to be much softer this time around. He pressed in from behind Sans, enough so that he could easily feel the heat pooling at his brother’s groin as his magic started to take shape. “Guess you really did want someone to walk in and take you. Fuck you until you were dripping cum down your thighs.”
Sans shivered. This time it was his heat that made him impatient enough to grind back with his magic, too eager to feel something after stopping and starting.
“Maybe. A little...” he said weakly, trying to peek behind him.
“Then it’s a good thing I found you isn’t it, my lovely little whore?” Papyrus’s magic had fully taken form now. Sans could feel it pressing into him from behind, hard and hot and just a few layers away from being right up against him. It seemed like his brother had infinitely more patience than him however, as he didn’t make a move to get any closer, simply rutting lightly against him right where he was.
“I want to hear you beg for me.”
Sans was already beginning to lose himself a little, for a second nothing registering but feverish warmth and wetness, desperation, and his brother’s hard cock pressing into him the answer to all his problems. He whimpered, one leg lifting like he was going to kick out, but he only ended up squirming uselessly again.
“I, fuck, please...” His face rubbed into the counter, spreading some drool on it. “I’m...I really need it...”
“Oh, is that right? You want me to fill you up?” The noise from Papyrus’s zip coming down sounded far louder than it had any right to be, “Maybe I ought to use you as my own personal toilet. How would you feel about that?”
Sans felt like he’d been zapped stupid by a ridiculous spike of arousal, probably his whole body lighting up a deeper shade of red. It was incredibly dangerous for Papyrus to know his kinks so well. Sans didn’t manage to get much of an answer out except for another involuntary twist of his legs.
“Gg...” he said into the countertop, shorts so soaked through it barely felt like they were covering anything anymore.
His brother moved in closer, letting the weight of his dick lay against the back of Sans’s sacrum through his shorts. His fingers trailed downwards, pressing in through the fabric and toying with the wetness there while rubbing against his tailbone. “If verbal answers are proving difficult, maybe you should try showing me how much you’d like that.”
Papyrus leaned forward, the long length of his body easily encompassing Sans from above, his arms coming down on either side of him. “Why don’t you undress for me?”
For the first time during the game, Sans found the appeal to making Papyrus work a little harder for it. Sans pulled against the hold.
“Don’t...don’t use me as a...toilet, don’t do that...”
There was a tense second where Papyrus froze, entirely unresponsive. In the very next however, he relaxed with a low, breathy laugh. “You were so eager for it just a second ago…I find it hard to believe in your sudden change of heart. Especially with you squirming underneath my cock like this with your pussy dripping wet.”
His brother brought his hands down to Sans’s shorts, thumbing into them with ease. “Maybe I just need to give you a little incentive.”
He tugged at them roughly, dragging them past Sans’s hips and part-way down his femurs before letting gravity do the rest. The fabric was drenched and heavy, falling down to his ankles with a wet slap against the kitchen tiles. It left the heated magic of his pussy completely exposed, the cool air of the room almost uncomfortably icy on his conjured flesh.
“Look at you...I can practically see you throbbing. Are you still going to pretend that you don’t want this?”
Sans squeezed his legs together, although from that angle he was almost certain it made his pussy stand out more.
“No...I can’t help it.”
“Then...” Papyrus said, voice so soft it was a wonder Sans heard it at all. As it was, it felt like every syllable was shooting straight down his spine, teasing at every vertebrae. “Why don’t you just give in?”
Sans rubbed back against Papyrus’s crotch again, this time only half aware he was doing it until he caught the noises he’d started making in his throat. He was getting more desperate, and the longer this kept up the harder it would be to hold back.
“I need it...” he whined.
“There’s a good whore. Honest at last.”
Papyrus rocked against his sacrum a few more times before he let his cock slip into the slick between Sans’s legs, readying himself with the wetness from Sans’s pussy. He brought one hand back to hold his length in hand, pushing only slightly past Sans’s folds and teasing at the threshold.
“I want you to use your hands and hold yourself open for me.”
Sans shook his head, but his hips bumped backwards again, trembling with need.
“No? It’d be a shame to waste this all over the back of your spine,” Papyrus drawled, pulling away from him, “But if you don’t want it in you, I can still enjoy the sight of my piss dripping off your bones.”
A dirty thrill captivated Sans, at the idea of getting punished like that, and he curled up his fists in front of him, though he couldn’t resist sliding one foot to spread his legs just the slightest bit wider behind him.
“Don’t. Just fuck me. Don’t do it like this.”
Papyrus shook his head, the motion close enough to feel as he followed it up with a kiss pressed to the top of Sans’s spine. “I’m afraid this is the price of disobedience, sweetheart.”
It felt like too sudden a change when Papyrus leaned up off of him, the solid weight against Sans’s back retreating. His brother stood back and readjusted himself, gripping his cock in hand, the head wet with Sans’s own fluids and glistening under the kitchen lights. Papyrus made eye contact with him, holding his gaze as he started to relieve himself.
Warm liquid splashed against the back of Sans’s spine exactly as his brother has warned, a shiver running through him from the point of impact. Papyrus continued to piss, letting his aim inch downwards until it was spilling over his sacrum and dripping off of it, just narrowly missing his pussy on its descent. The stream angled off to the side until it was trickling down his leg and it felt like his brother had marked every inch of him in it. All except his pussy, which clenched when a stray few drops passed, sliding just pass his clit.
It was driving him crazy. Whatever urges he’d been suffering before, now he felt like he truly couldn’t stand it. He let the side of his face press into the counter, and he reached back with his hands to belatedly hold the opening of his pussy open, his legs still trembling under the leftover streams of warmth.
Papyrus laughed, a deep, hoarse sound that wasn’t doing Sans’s trembling any favours, “It’s a little late for that. Can’t use you like a proper toilet without any piss left, can I?”
He wasn’t done though, that much was evident by the way he hummed as if in thought. His brother took a step closer to him, reaching out and letting his fingers brush against Sans’s stretched folds, dipping shallowly into his pussy, “I do appreciate your attempt at correcting your earlier behaviour though...I can tell you regret your actions.”
His brother leaned back over him, one hand still playing with his pussy while the other balanced him against the countertop. Fingers circling Sans’s clit, he mumbled an offer against the side of his skull, “So, tell me, pet...if not a toilet, how does being my cumdumpster sound instead?”
Sans’s breath came out shaky. It was hard to stay still when he wanted to keep grinding against his brother, the finger on him felt so good.
“Oh god. I want you to blow a load in me. I can’t...stand it anymore.”
Papyrus’s breath hitched as Sans spoke, and he could feel the press of his brother’s cock against his tailbone throb with interest. He removed his fingers and wiped them against Sans’s leg. “I’m going to pump you so full, you won’t be able to wash me out for weeks.”
With the promise growled out, Papyrus took hold of himself again and rubbed against Sans’s wetness twice before pushing into his stretched open pussy. He sank in with ease, Sans’s slickness more than enough to make the passage smooth. He gave a groan as he slipped in deeper, a full body shiver racking through him and consequently through Sans underneath him as well.
Sans gave a long whimper at its entry, barely playing at this point as he rocked his hips backwards. His words came out rapid and muffled into the counter.
“Ah. Uhn. I needta be fucked. I need to be fucked so bad.”
His brother swore at that, body bearing down heavily on top of Sans as he fucked him with renewed vigor, filling him up to the brim before withdrawing just enough to make Sans want it even more. The pace was fast, almost ruthless in how quickly Papyrus kept slamming their hips together, cock stretching him out even further than his fingers could as he held himself open. Sans’s grip was slipping too, phalanges needing to regain purchase with every squirt of slickness that escaped from the mess his brother was making of his pussy, precome dribbling out of him steadily.
“Is—is this what you wanted?” Papyrus panted, not letting up for even a second, “Your pussy tight around my cock while I wear you out? Being nothing but a toy for me to use?”
“Oh fuck,” Sans gave up his hold on his pussy, slipping his fingers out to let Papyrus fill him entirely. He brought his arms back in front of his face on the countertop, bracing himself for Papyrus’s thrusts and simply sinking into enjoying the pure physical fulfillment. “Oh fuck, oh fuck, yes, I wanted it, it’s so good...”
“God,” his brother groaned, pressing into him as best as their positions could allow. Papyrus’s cock made loud, slick noises as he kept that punishing pace, twitching and throbbing deep inside of him. He turned his head enough to press a closed mouth kiss against Sans’s shoulder. “Fuck, Sans. You feel so fucking perfect around me.”
Sans hardly registered that they’d both slipped, he was too caught up in finally getting exactly what he needed, and his brother’s body pressing over him, enveloping him in a warmth he was fairly certain emanated from his pulsing soul.
“Ahh. Boss. Boss...Boss...haa...ah-h...”
Papyrus’s thrusts were finally starting to get a little more erratic, and Sans could tell he was getting close. His brother fucked into him harder, deep enough that it felt like he was testing the limits of what Sans’s magic could take. Papyrus uncurled one hand from where it had somehow wound itself protectively around Sans’s middle and brought it down to his pussy. While he continued to pound into him, Papyrus rubbed firmly at the swollen magic of his clit.
Sans came almost immediately, head tilting back to moan loudly as relief and pleasure washed through him. His pussy kept giving rippling contractions over his brother’s cock as Sans’s noises fell into something like a mess of whines.
“Boss...” he mumbled, “want your cum in me...I wanna fucking drain you dry...”
“Fuck .” Papyrus swore, voice choking off as his body shuddered with release. His brother rocked against him as he came, hips still smacking together. His cum flooded into Sans with a force that instantly made him feel full, even as more continued to pump into him. He could feel it start to drip out of him, dribbling down his clit and onto the tiles beneath them as his brother continued thrusting into him, riding out his orgasm.
Sans almost slipped down and collapsed, the stimulation making him weak.
“Ohh...oh fuck...”
He closed his eyes, concentrating on how good everything felt, his knees almost knocking together as his body started to go limp.
Coming down from his high, his brother seemed to notice how close Sans was to teetering off the edge of the countertop because he re-wrapped an arm around his waist and supported him.
“Careful, brother.” He said, voice gone downright soft in comparison to earlier. Still, he didn’t help Sans up, much more interested in keeping him pressed against the countertop as he started to pepper kisses along his shoulder blades and spine. “You did so well.”
Sans was so oversensitive, he moaned a little just from the kisses. He rolled his head to peer back at his brother.
“Boss? Is that you? I didn’t hear you come in. Listen, I’m really sorry, but I just cheated on you with this super dashing burglar...I couldn’t help it, I’m too weak-willed...”
At first, Papyrus looked confused. Then his expression quickly morphed into exasperation, followed by a smug little smile. “Cheated on me with a burglar, huh? Would you say that he...stole your heart?”
Sans felt a thud from his own soul.
“Oh god, Boss, you’re amazing.”
Papyrus’s face, though already flush from exertion, went just the slightest shade darker. “I—I already know that, Sans. I don’t need constant reminders.”
He leaned back upright, a hand still against Sans’s back to keep him from tipping over the edge. It seemed like he pulled out with some measure of reluctance, though it was possible the feeling was mitigated by the way his cum slopped out of Sans’s pussy as it clenched when Papyrus backed away. His gaze certainly stayed fixed there long enough. Finally, he turned back to Sans, flipping him around and pulling him up so that they were chest to chest.
“You performed admirably, brother,” he said, sweeping in for another gentle kiss, “Some rest is typically par for the course in these circumstances. What would you like to help you relax?”
Sans felt like he had to reboot his brain after he heard his brother suggesting that he, Sans, relax. Then he was immediately gripped with a greedy compulsion to take advantage of the phenomenon.
“Lying in bed,” he blurted out first. “The really fluffy comforter. Do we have cocoa?”
Papyrus blinked at him, a faint sort of amusement crossing his face. “All of that is simple enough to put together. I’d have thought you’d want to get clean first, though?”
“O...oh.”
Sans briefly looked himself over, like he needed a visual reminder of the piss and cum all over him.
“I guess I...you really think of everything, Boss.” He peeked up at Papyrus. “...shower together?”
From the way his brother’s face lit up red at the suggestion, it was clear that he was reading a little more into it than an innocuous suggestion. “The- the point of you showering is to get clean , Sans. Going in together is-” He trailed off as his gaze wandered downwards, no doubt catching sight of the way Sans’s legs were still faintly trembling, “Though I. Suppose you might need a little help with that...”
“Boss, I. I really don’t think I could go again tonight. I was literally suggesting we both get clean at the same time, as crazy as that sounds from me.” He smirked. “But then, you’re the one telling me to ‘relax,’ so maybe we fucked so hard we switched for a day.”
It used to be that seeing Papyrus get embarrassed was a rare occurrence. Somehow, in the last few days, it felt like he’d seen it more than he had in years. Even now, his brother turned his head to the side, avoiding eye contact. “That. Sort of phrasing could have confused anyone. Though, it—it doesn’t matter now, in any case. Let’s just go and get cleaned up already.”
Clearly eager to cut the conversation off there, Papyrus scooped Sans up into his arms, supporting his weight easily as he turned out of the kitchen and moved to carry him up the stairs.
