I headcanon Burgerpants as having an embarrassingly thick bubble butt-not absolutely disproportionate, but enough for it to be very noticeable. Nice Cream has some fun with it. Bonus for rimming/facesitting.
Instead of Chara killing Flowey, they give him the souls they've collected and he regains his old form. Together they go to the surface and begin the process of eradicating all humanity as a gleeful yandere couple; devoted to one another, but completely unstable and prone to possessiveness and violence
would anyone be kind enough to help me hash out the plot and other details of my human au sans/reader fanfic in which the (gender neutral) reader finds sans and papyrus, who were kicked out of home by their abusive parents, huddling under a bus shelter late one rainy night and takes them in?
in this au sans is 17, ftm trans, and has depression, ptsd and really low self esteem, and papyrus is 10 and autistic. their parents kicked them out bc they're fuckwads who couldn't deal w/ their "abnormal" children. the reader is uni-age and doing a teaching course. that's p much all i've got so far so if you're interested in helping me just hmu and i'll give you my skype
"Sure you don't need help?" the phone says and you jerk back to attention, nearly forgetting that you're still on the line.
"Yeah, I'm good. Just need to buy more food and clothes," you take another glance at the blanket burrito resting on the plush couch. An eye stares back, the older one is awake, for how long you don't know but they curl around the smaller one with a narrowed eye. They still don't trust you. "And toys. Definitely some toys."
"Alright then, ring me if you need help."
You nod even those the other people can't see and hang up, walking into the kitchen. You don't know much about taking care of a teen and a kid, considering how you yourself just started university not too long ago.
Heck, you're not even sure how to cook without the help of the miracle microwave your mom brought. What would you give for a How-To-Adult book right now.
Movement at the corner of your eye has you twisting around, a knife in reach. The older sibling has gotten the courage to look around, but hasn't left the little kid.
You sigh and open your cupboards, looking into your humble hoard for something edible. A can at the back peers up at you shyly and you raise your brow at it.
Alphabet spaghetti it is.
You need to leave for your part time job, but you left a note - explaining that you're going for work and this is your house so please don't wreck everything- on the coffee table and a set of keys. You also left two covered plates of the spaghetti there.
When you close the door behind, you hear a delighted cheer of a child from inside. You smile a little, then really, really hope they won't wreck the house.
On the bright side, you don't have much worth stealing. Besides your really plushie couch but you don't think they could drag it out of the door.
Yeah, you really need to get that book.
-
Hi, i know this wasn't really a prompt but yeah. You could add in things like trying to get the babies back into a somewhat working state. Maybe a Bath Time or going to the park on a not so crowded day to be comfortable round the reader. Sans would probably want to find a job to repay the reader and support his bro so yeah. Maybe he could start with organizing the reader's papers.
...and of course, finding the parents so the reader can kick their asses.
Toriel asks Alphys (and Undyne if desired) For advice on her sex life
Toriel has a problem in that she tends to choose men who are either A) on the unimaginative/vanilla side (Asgore) or B) Enthusiastic but Lazy (Sans) (either pairing is fine) - knowing that Dr. Alphys has a rich fantasy life and at least some NSFW Anime in her collection, she commissions her to write some kind of subtle-but-not-too-subtle fanfiction that she can conveniently leave around the house as 'inspiration'. Hilarity or Kinkiness or both ensue.
Incase I'm not clear - this should be a piece of fanfiction, written as Dr. Alphys (and Undyne or Mettaton if you want her to bring them in o the process) writing an inspiring AU for whomever Toriel's current partner is.
Fluffy, playful sex with no jealousy. Maybe the three of you are in a polyamorous relationship, or maybe Sans and Toriel just brought you home for the night. Nonbinary or gender neutral reader, please.
Napstablook is having trouble adjusting to their new robot body, but Mettaton wants them to feel good and confident about it. What better way than to show them just how much he loves every inch of their new body?
Burgerpants is getting a reward for all his hard work, and Mettaton wants it to be special. Aka Mettaton rides his overworked employee. I'd prefer if Mettaton has a cis males' genitalia in this, but its fine if you want to do something different.
I have the weirdest boner for skelebros in heat, disregarding the anatomical impossibility of it?????? So can someone give me some Papyrus/Sans where both are in heat at the same time and wind up fucking?
Sans’s didn't know whose idea was it to string mistletoe above the kitchen doorway. Whoever they were, he acknowledged their cunning and seasonal prank mastery, since he's fairly certain people don't put these things up unironically nowadays.
Sans stood beneath the doorway, staring up at the toxic, parasitic plant that dangled innocently from it. Across from him, Papyrus squinted at the bundle of leaves, puzzled by its place on the skeleton brothers’ ceiling.
“Sans, did you buy another house plant?” Papyrus asked. Sans snorted at the memory of the last time he tried to take care of something living. Rest in peace Planty, you will be missed.
“Nah, I could never replace the last one,” Sans replied with a shrug of his shoulders, leaning against the door frame.
“Then… What is it?” Papyrus asked again, looking more and more confused with each passing moment. Sans would have liked to leave him floundering for a few moments more, since that bewildered expression was so comical, but he could never leave his bro hanging.
“Mistletoe.”
“It does not look like an appendage, nor a destructive weapon!”
“That's because it's a plant.”
“Then what is it doing on our door frame?”
“It's a human tradition. If two people pass under it at the same time, they gotta kiss.”
“Why?”
“Gee, I dunno. Christmas laws. Can’t break ‘em.”
Papyrus's confused expression morphed into extreme concern at the thought of breaking the “Christmas laws”, as Sans so wisely put it. The smaller skeleton chortled and concentrated his magic, creating a transparent and soft pair of glowing blue lips. He puckered them teasingly, moving just an inch forward.
“C’mon, bro, it's the rules,” Sans teased, smacking his magical lips in a playful manner and punctuating the move with a flirtatious wink. Man, this whole mistletoe shebang was great for prank opportunities, he wondered why-
Every thought process slowed to a sudden halt when Sans felt a pair of warm, pliant lips against his. He jolted in surprise, finally realizing just how close his brother’s face is, and holy cow he's kissing Papyrus, and more importantly, when the hell did his innocent brother learn how to summon lips?
Sans stood there, like a deer in headlights, as Papyrus's lips pressed against his own. They were warm, and very soft, almost satiny. Papyrus stood just as immobile as his brother, probably unaware of what to do.
Sans pulled away first, his hands flying to his mouth and a blush threatening to dye his cheeks. He fought off his surprise. Play it cool. Nothing's wrong.
“Jeez, Pap, ya didn't have to kiss me on the lips,” Sans said, fighting off the shakiness in his voice. This would all be water under the bridge. He tried to laugh off his disappointment and forget the feel of Papyrus's lips. “That was pretty funny, bro. You just came on over and planted a- mff!”
Papyrus interrupted him, again by kissing him, but this time he grasped the front of Sans’s jacket and hauled him forward until their lips connected with bruising force. Sans couldn't stop the moan that bubbled up in his throat in time.
Papyrus pulled back, his cheeks orange and fistfuls of Sans’s jacket caught in his hands. Sans tried not to look mortified. “Uh…” Words, for the moment, failed him.
“Again.”
“W-what?”
Papyrus's lower lip caught between his teeth and Sans felt his gaze straying to the sight. “Kiss me again, and really show me how!” Papyrus looked down at him and his grip softened. He smoothed out the wrinkles in Sans’s jacket- not like the smaller skeleton cared at all- bashfully. “Please?” he added.
Well, Sans couldn't say no to that face.
“Can you summon a tongue?” Sans asked, his own already resting just behind his teeth. Papyrus nodded. “Awesome.”
Sans gripped the back of his brother’s head and hauled him down into a third kiss. He had to stand on his tiptoes, even with Papyrus bending over, but he could honestly give less of a shit. Their lips slid together perfectly, moving in an intricate dance that sent shivers up Sans’s spine and provoked a surprised gasp from Papyrus. Sans took the opportunity to press his tongue forward, slipping it with little trouble into Papyrus's open mouth.
His brother groaned and clutched at Sans’s shoulders, his fingers digging into his jacket. Papyrus's tongue responded shyly, but soon they moved into a passionate exploration of each other's mouths. Papyrus was unsurprisingly vocal, letting out soft whispers and moans as Sans’s experienced lips and teeth and tongue worked their magic (pun intended). Sans caught Papyrus's lower lip between his teeth and gently applied pressure, drawing a strangled noise from his brother.
He found himself pressed up against a wall with little warning. His head fell back in surprise and their lips parted with a slick pop. The two brothers stared at each other, awestruck. Then Sans snorted and Papyrus giggled, and soon they collapsed onto the floor in a pile of helpless laughter.
Sans made a mental note to thank whoever put up that mistletoe later.
Based on this comic: https://40.media.tumblr.com/d61de3b804596dd78b26b8b5f4e8d399/tumblr_ny78goakme1qc74hno8_r1_1280.png
Basically the premise is that two ghosts possessing the same object is the equivalent to ghost sex. So you can either go the route that they did it just for curiosity without knowing what was going to happen and being pleasantly surprised by how good it feels - or knowing what it would be like and wanting to try it out.
Sans comes across Mettaton topping Papyrus one night. He gets really riled up by it and starts jerking off to it and Papyrus's moans of pleasure. Bonus if Mettaton is secretly aware that Sans is there the whole time and says or does things because he knows it will get a stronger reaction out of Sans.
So basically, Undyne wanted to hit Sans (not hard, she just got annoyed) and Papyrus jumped in front of her to protect his brother. Everyone is weirded out and stuff and they find out that he only has one HP. Sans is ashamed of this, but his friends reassure him.
Alphys had forfeited long ago. Her magic just wasn't meant for fighting, and Undyne wasn't going to press her for it. She had tried her best, and although she hadn't managed to land even a single hit, that was something Undyne would always respect.
Now, Papyrus, he was the fun one. He had been the one she'd initially started sparring with, a sport that had extended to the rest of their friends. Even the queen had gotten in on the fun earlier. Her attacks were more restricted than the kings, less variety, but much harder to block.
"Try dodging," Papyrus had called to her.
"Fat chance!" Another streak of flames had gotten past her guard, not hot enough to do any damage but only just falling short of burning. Blocking really wasn't the best defense against fire magic.
Bone attacks, though, they were fantastic. She and Papyrus had matching grins as they threw bullets at one another. It was a deviation from his normal style, chucking bones instead of weaving them into patterns to be dodged. He wasn't too stubborn to adjust his strategy. It was good training for him, if he was to ever encounter an opponent that was able to hold their ground even under the effects of Blue magic.
Their match ended when she managed to lob a spear through his defense, sending it between two bones striking him in his chest. He staggered, the bones around him dissipating, and the rest of Undyne's bullets paused.
A low chuckle sounded. Undyne felt her jaw tighten when she looked up at Sans. Papyrus' brother was lounging in a chair, one eye peeked open to watch them spar. "I'm gonna have to call it, bro. Undyne's got ya beat this time."
Had that come from any other person, Undyne would have laughed and claimed her victory with no shortage of gloating. From Sans, though, she couldn't even bring herself to crack a smile. He leaned back further in his chair, eyes closing, fully intent on going back to sleep, and Undyne felt her eye twitch. He hadn't done anything. Not a single bullet had been conjured by Sans, not a single match had been fought with Sans. He'd just napped through it all.
She tuned back in to what they were saying at Alphys' voice. "I think he's right, Papyrus. You, uh, look pretty beat up."
Papyrus puffed out a sigh, clambering to his feet. "Alright, if you two insist. But do not think this is the end, Undyne!"
She managed a toothy smirk at that. "You wish." As he shambled off to rest, Undyne found herself looking back to his brother. "Hey, Sans!" she called. He opened his eyes, making a noise of acknowledgement. "You're up, bonehead!"
His smile slipped, just a bit. "Nah, I'm good," Sans said, waving a hand dismissively. "Watching you guys has me, heh, bone tired."
There was a low groan from Papyrus. Undyne looked to him, waiting for him to drag his brother to his feet and make him participate. The skeleton was silent, though, just watching the two of them.
Sensing no further disturbance, Sans relaxed into his chair again, eyes closed.
Undyne felt a stab of annoyance. A strained grin pulled at her lips as she materialized another spear, which spun so it pointed at Sans. "Yeah? Too bad!" A flick of her wrist had the bullet flying at Sans.
"Undyne, no!" It was Alphys who screamed. Undyne swung her head around to look at her girlfriend, whose hands were clasped over her mouth.
Behind her, where Sans sat, was a sharp "Ah!" of pain.
Papyrus had collapsed onto his knees, kneeling in front of Sans. The last glow of her spear was vanishing.
"Papyrus!" Sans scrambled out of his chair in record time, going to help his brother. Papyrus had already recovered, though. He rose to his feet, shrugging off Sans' concern, and glared at Undyne.
"What," he seethed, "were you thinking?"
She stepped back, not out of fear but just shock. Never in her life had she seen Papyrus look so angry. "Jeez, Papyrus, chill out."
"You attacked my brother!"
"Because he wasn't doing anything!" Indignation flared in her chest. "Do you just want him to lay around all his life?"
Sans said something to his brother, but Papyrus didn't heed him any mind. "No, but you don't have to go throwing bullets at him!"
"Papyrus," Sans' voice was warning.
"What the hell is your problem?" She marched close to him, glaring right up into his eye sockets. "You're the one that took the hit, it barely took over one HP!"
"And that would have killed him!"
"Papyrus."
They both fell silent. Undyne stared at Papyrus, who was giving Sans a stricken look. "Brother," he stammered, "I… I'm…"
Sans' shoulders had hunched up. The fur of his hood concealed most of his cheeks, but it didn't hide the way his eyes had gone dark. "She didn't know. 'S not her fault."
"Hang on." Neither of them looked at her, but Undyne knew she had their attention. "What's Sans' HP?" Behind her, she could hear Alphys tentatively approaching.
Papyrus looked to her, and then to Sans, who gave the slightest of nods. "It's… One. He has one HP."
Undyne felt her soul give a twinge. It settled on her slowly, like a blanket of snow, until she closed her eyes and shuddered. "So that one hit…"
"Would have killed me." Sans' voice was tight. He turned his head away from them. "But Papyrus took it, I'm alive, everybody knows, so let's just drop it." He turned, trudging off.
Alphys broke away to scurry after him. "W-wait!" He stopped, allowing her to catch up, and Undyne and Papyrus were close behind. "Sans, are you okay?"
"Well I'd be dust if I wasn't."
His suddenly-joking tone didn't dissuade her. Undyne felt a brief flash of pride, watching her girlfriend hold her ground. "No, I mean are you feeling alright? You look pretty shaken."
Sans nodded his head firmly. "I'm telling ya, Alph, I'm A-okay. Maybe a little rattled…" He grinned, but it fell short, and after a beat he let it drop. "Seriously, guys, let's just forget about it." Soon enough, he was grimacing. "Really. I get it, I've got one HP and that's pretty fucking pathetic, but if you don't mind I've got some slacking off to do, so…"
"Brother. You know we don't think of you that way, right?" Papyrus' voice was small.
"Yeah, Pap, I know."
Alphys hesitated. "Do you think of yourself that way?"
This time, he shrugged. It was answer enough, and before Undyne could blink, Papyrus had scooped his brother up into a hug. "Sans, do not think of yourself that way! You are my brother and an amazing one at that!"
"Aw, jeez, Papyrus." Sans tried to squirm free, but Papyrus was far from over.
"You may be an insufferable lazybones but you are a dedicated one! I've never seen someone be so determined to slack off, and that in itself is admirable." Papyrus finally Sans down, who seemed overwhelmed even as he tried to laugh off the praise. "Besides, you read me a story every night and you help take care of Frisk, and I appreciate that very much."
"Yeah!" Alphys jumped in with a nervous smile. "You really care about us, Sans. And even if you're not a fighter, w-well I'm not either. Who cares if we prefer to lay in bed some days?"
Alphys went quiet, and both she and Papyrus looked to Undyne. She rubbed the back of her neck, staring at the ground before forcing herself to meet Sans' eyes. "Alright, yeah, what they said. I'm sorry I almost killed you and stuff. To be fair, I did actively try to kill the human." She cracked a smile. "And, um. Fighting isn't always the answer, anyway. Actually, it's probably best to avoid it. Even if it is a lot more fun than diplomacy!"
Sans was silent. For a moment, Undyne cringed, sure she'd messed up even more. Then his grin returned full force, and he broke into laughter. "You're all a bunch of saps," he sniggered. "Apology accepted. But only if you wash the dishes tonight."
Papyrus was sure to make a very, very large dinner.
Sans was at Grillby's. Again. The shows on television were: a quiz Papyrus remembered all the answers to, a drama which made him feel sad, an old news report, and a cooking show where all the recipes needed ingredients Papyrus couldn't find.
Papyrus considered phoning Undyne, but she was probably busy with important Guard stuff. Or watching shows with Alphys - it was good that she didn't ignore her other friends for him!
He sighed, feeling... he wasn't sure. A little down, maybe?
Well, if he was down he just had to cheer himself up! Papyrus turned off the TV and rearranged himself on the couch, spreading his legs impolitely wide and sinking back into the cushions. Just the thought of what he was going to do boosted his mood, stirring anticipation in him as he loosened his chestplate and pulled it off.
He started by drawing the tips of his fingers over his lower ribs. The soft touch always made them tingle - he was dreadfully ticklish there. He stroked again, and again, slowly working his way to his sternum, and then slipped his fingers into his ribcage and stroked the inner surface. It felt so good he had to moan, so he did it again, reaching up further and closer to his soul. The proximity sent chills through him - a direct touch wouldn't feel good, not this early, but the tease...
He left one hand there, barely moving, and slid the other up his femur and then back down, thumb rubbing in small circles. He scratched as gently as possible, shivering at the tingles it caused as he slowly dragged his fingers closer to his pelvis. Dimly, he became aware that he hadn't removed his hotpants yet. He smiled, rubbing harder over them, teasing himself with the blunted sensation - then reached in and stroked hard over his exposed inner pelvis, letting his head fall back as he moaned again, louder. He started rubbing his sternum again at the same tempo as his pelvis, feeling his soul start to throb as he shifted restlessly - keep going, hand moving so slowly back to his sacrum, and then it would trail upwards till he had both hands deep in his ribcage ready to cup his beating soul -
"hey, pap? you okay - what're you doing?!"
Papyrus huffed, opening his eyes to see Sans stood in front of the couch looking stunned. Had he really been too intent on what he was doing to hear the door opening?
"T-TOUCHING MYSELF, OF - AH - COURSE!" The interruption was making it harder to reach his peak, but, Papyrus told himself, there was nothing stopping him from having a second round afterwards. And maybe a third.
Sans' face twisted in a very confusing way. "uh, you mind stopping?"
"WHY?" Stopping always left him feeling irritable, unsatisfied. Even just pausing lost some momentum, making it less satisfying.
Sans made a choking noise at the question. "please, bro?"
"I - AH -" Papyrus dragged his fingers up his spine, let his other hand slip into a better position to reach his soul - "I'M AL-MOST DONE, SANS, SO-"
"ohgodpleasedon'tgetoffwhilewe'retalking."
It took a moment for Papyrus to figure out what his brother had said. Then he growled as he dragged his hands back out of his ribcage. "WHAT IS IT?!" he snapped, stroking his ribs defiantly.
Sans glanced around desperately, eyelights flickering. "uh. i. (god, i don't want to do this.) how long've you been - touching yourself?"
"TODAY?" Papyrus asked, not certain why Sans would want to know.
Sans choked again. "no, no, nononononoooo. i, uh, i mean, at all?"
"EVERY DAY," Papyrus said slowly, "THAT'S HOW SHOWERS WORK. YOU NEED TO -"
"Pap!" Sans was definitely flushed now. "how fucking long have you been masturbating?"
"WAS I MEANT TO KEEP TRACK?" The longer this conversation went on, the less Papyrus understood it.
It didn't help when instead of answering his perfectly reasonable question, Sans whined like one of the Dogi who'd just had a bone stolen from them and turned away. "i can't do this. i cannot fucking do this. this is not -"
"WHAT'S WRONG?" Papyrus folded his arms, finally accepting that he wasn't going to be allowed to get back to pleasuring himself until the conversation was over.
"what's -" Sans spun to face him again, then breathed a sigh of relief at seeing him be less blatant about what he'd been doing. "do you not know that masturbation is supposed to be private?"
Papyrus felt more confused. "WHEN DID THAT BECOME A RULE? BECAUSE YOU WERE ALWAYS VERY LOUD WHEN YOU -"
Sans' eyesockets widened. "say what?"
"- AND UNDYNE OFTEN INVITES ME TO STROKE PARTIES WITH HER AND ALPHYS -"
"s h e d o e s w h a t ?"
"LIKE YOU HAVE WITH GRILLBY," Papyrus continued, "AND DOGGO DOES IT ALL THE TIME IN HIS STATION - EXCEPT HE USES HIS TONGUE -"
Sans whined again, putting his hands over his earholes. "i'm in hell. this is hell. what the hell."
"- SO I REALLY DON'T UNDERSTAND WHY YOU'RE MAKING SUCH A FUSS ABOUT THIS?"
Papyrus stared at Sans inquisitively.
Sans stared back.
"papyrus. please never masturbate on our couch again."
"DOES THIS MEAN YOU'LL STOP DOING THAT TOO?"
Sans gave a muffled scream. "i promise, paps, after this conversation i'm not touching myself again for another decade."
"REALLY? I THINK THAT WOULD DISAPPOINT -"
Sans did scream then. Loudly. For a very, very long time.
"FINE." Papyrus stomped off to his bedroom.
He never did find out why Sans had come home from the bar early that night.
