Chapter Text
He woke to darkness, muffled voices, and...vibrators. Sans wriggled, but he wasn’t sure if he was trying to free himself or push the one lodged inside him deeper. It, along with a number of smaller vibators dotted around his body, hummed away as he achieved consciousness, horny and confused. He groaned, the noise warped by the ring holding his mouth open, as his wakefulness made the sensations stronger, but not strong enough.
His magic had formed in his sleep somehow, his cock already hard and aching. Sans tried shifting again, but he was thoroughly bound. He was on his back, his legs forced up and bent, leaving him uncomfortably exposed. Moving his arms was equally unsuccessful as they were bound together in some kind of leather sleeve, held tight to his chest by a length of rope tied to a collar.
He heard laughter and the sound of dishes. Someone was nearby, outside of this--he wasn't really sure--but it just felt like a big box. As he grew more aware of his situation, his breathing grew labored and ragged. Between the constant stimulation of the vibrators and his oncoming panic attack, he could hardly think of his own name, let alone figure out just what the fuck was going on here.
Everything built up in him before breaking like a wave and dulling again, but each time it left him that much more worked up. This went on for what seemed like days. Each time Sans regained that fleeting bit of rational thought back, he tried to find some weakness in his bindings. Eventually, though, he couldn’t even manage that much, as he felt himself approaching his orgasm.
Underneath the pleasure, his soul was beating hard and fast, with a dull ache. It felt like it was being squeezed, the overflowing fear, pleasure, and panic about to burst out of it at the seams. Even as he hoped his orgasm would come soon, he was ashamed of wanting just that. Sans just wanted release, and since he didn’t seem likely to be free of his bindings anytime soon, the other kind would do.
He groaned softly as he neared the tipping point, the slight bit of movement he could manage with his pelvis repeating unconsciously as he felt it build and build until, with a cry, he came. Cum splattered up and hit the top of his box with a unsettling splat. The majority of it ended up on his bound arms and rib cage, and proceeded to slowly drip down through him.
Sans panted, glad that it was over, until he realized that the vibrators were still going. As the extreme pleasure of his orgasm faded, the constant vibration hit his over sensitive body like a sack of bricks. He whined, feeling that much more weak and useless than before.
The muffled voices grew louder, and he heard footsteps come over to where he was trapped. Unsure if the monster on the other side was friendly or not, Sans kept as still and quiet as he could manage. There was a lot of rustling and crinkling paper.
“sure i can’t start with the big one?” that voice sounded familiar to Sans. He tried to get his mind to function and place it.
“OF COURSE I’M SURE!” Sans winced at the loud voice that seemed to be right above him. No, there was no way.
“oh, alright,” the deeper, mellow voice answered, followed by the sound of paper tearing. Sans listened intently for any indication of what was going on. There was a laugh, “what’s this?”
“YOU’LL SEE! OPEN THE NEXT ONE!” More unwrapping and chit chat that did nothing to enlighten him. Eventually, he felt his container move slightly. “ALRIGHT, NOW YOU CAN OPEN IT.”
“you really went overboard this year, didn’t you, bro?” Sans’s eyelights shrunk as light suddenly flooded the small space. As they adjusted, Stretch came into focus, looking down at him with a grin slowly spreading across his face.
“MERRY CHRISTMAS, PAPY!” Blue yelled from somewhere nearby. Stretch took a moment to look over Sans. The bound monster felt the urge to shift and cover himself, but the rope didn’t allow him to do more than rock himself very slightly. His pelvis squelched uncomfortably against the cum pooled at the bottom of the box.
“it’s perfect, sans. thank you,” Stretch looked away to the left, presumably where his brother was. Sans tried to form words, but they came out as grunts, not that either of the other two were paying him any mind.
“he did make a bit of a mess in the box, though,” Stretch was saying, and suddenly Blue popped into view.
“RED, LOOK AT WHAT YOU’VE DONE!” Blue began to admonish him, wagging his finger at him like he was- “BAD DOG!”
“hut!?” Sans stared up at Blue, uncomprehending.
“I’M SORRY, PAPY. I LEFT HIM ALONE FOR TOO LONG.” Blue deflated, clearly upset. Were they talking about the cum? What did Blue expect, with the vibrators? It wasn’t like Sans had wanted to cum. He didn’t want to do any of this. For that matter, the damn things were still going.
“Hhh,” he tried to get their attention, but they continued to ignore him, retreating from the box instead.
“it’s okay, sans. not your fault. he just needs to be punished. some training, and i’m sure he’ll behave better.”
There was more laughter, and the sound of paper crinkling.
“I GUESS IT’S FINALLY A GOOD THING YOU’RE SO LAZY ABOUT WRAPPING.”
Stretch came back into view, chuckling, still looking in Blue’s direction. He reached down into the box to pick Sans up.
Seeing the hands reaching to touch him flipped Sans’s panic switch back to maximum. He jerked in the ropes, nearly lifting his back off the bottom and shaking the whole box. Stretch finally looked closer at his face.
“hey, be a good dog and take your punishment.”
Sans’ wriggling wasn’t enough to prevent Stretch from taking hold of him, or from lifting him easily out of the box and setting him down on the floor. He was still on his back, with his legs spread out and his half-erect cock in full view, dripping cum down his arms and chest. Stretch made a ‘tsk’ noise.
Sans looked away from him, to the side. Blue had taken some newspaper off of Stretch’s carelessly wrapped gifts and rolled it up. Sans gave another panicked jerk as Blue approached, but the rolled newspaper was handed into Stretch’s waiting open palm.
“YOU SHOULD BE THE ONE TO DISCIPLINE HIM, PAPY. HE SHOULD GET USED TO YOU.”
“okay, okay bro.”
Stretch lowered his arm and lightly bat the newspaper against the end of the vibrator sticking out of Sans, making Sans grunt in distress. That shouldn’t have felt good, shouldn’t make Sans’ cock bounce against his stomach in renewed excitement.
Stretch moved the newspaper lower, below where the vibrator was sticking out, and rubbed it against the fuller flesh the magic had formed there. But he wasn’t going to...he couldn’t really…
Sans needed to protest, to somehow make it known that none of this was all right and he was definitely not on board for whatever sick games they’d roped him into. All he could manage were strangled noises of indignity.
Stretch was looking down at him with one eyebrow raised.
“bad dog. no messes.”
He pulled the newspaper away, then swung it back to swat hard against where it had been rubbing Sans a moment ago. Sans had been determined not to make any noise in response, but he couldn’t hold back the surprised yelp at the force Stretch had used on him.
The stinging pain of the blow persisted as Stretch pulled his arm back again. Sans made more garbled noises in an attempt to get them to pay attention. He winced as the paper started its descent, landing on his ass with a sharp crack. He cried out, the pain that much worse as it built upon the previous hit.
He began to cry, not that Stretch seemed to care, and could only whine as the third and fourth blows landed. His flesh felt like it was on fire, and Stretch reaching down to grip it firmly didn't help. Sans arched, as far as the restraint would allow, and cried out as the sensitive flesh was squeezed and pinched.
“think he’s learned his lesson?” Stretch asked absently as he he watched Sans squirm.
“I DON’T KNOW,” Blue mused. “IT IS TEMPTING TO PAMPER A NEW PET, BUT IF YOU GO EASY ON HIM NOW, HE MIGHT END UP DIFFICULT.”
Stretch continued kneading the sensitive flesh as he considered the words. Sans stared at him, horrified by the implications. Were they planning on keeping him? He tried to look at Blue, hoping to find some clue that this was just some terrible, tasteless joke, but he could only see the barest hint of his double’s skull from his position.
He was so caught up that he didn't notice Stretch had stopped touching him, or that he had raised his hand again. The series of quick, sharp smacks, three to each cheek, made him yelp and cry out. When they were over, Stretch stood and stepped back, giving Sans a once over.
“i think that’s good. i don’t want to spook him too badly, either.” He said. Sans tracked his movement as he set down the newspaper. “it would be nice to play with him today.”
Stretch dug around a pile of wrapping paper and boxes for a while as Sans watched closely on.
“where did it go…” he muttered.
“YOU DIDN'T LOSE IT, DID YOU?” Blue chimed in, sounding disappointed. “ALREADY?”
“nope, here it is.” He straightened suddenly holding up...a tiny collar? With a tag on it? What possible use could that have? The item seemed innocuous enough to Sans, but Stretch seemed awfully pleased to find it, and that was reason enough to worry at this point.
He knelt down in front of Sans and gripped his cock, giving it a tug that had Sans gasping. Lowering his head, Stretch stared down at his member while holding it steady. The tiny collar was slipped over the tip and down the shaft, squeezing him uncomfortably as it went. He tried to squirm as the pressure of it moved down further, finally settling at the base where it quickly became painful. Stretch stroked him a few more times, which didn’t help at all.
“the perfect no-cum collar for a mess-maker like you,” Stretch said with an eerie fondness in his voice. He stroked Sans’s skull gently behind what Sans was now realizing were probably some kind of ears. Just like Blue, to obsess over the details, even when kidnapping someone.
Stretch stood back up and settled himself on the couch. He grabbed one of the boxes and rooted around inside. Out came a remote, and then another, and then two more. Sans watched as he looked between them, deciding which to use. Nervous anticipation washed through Sans. Stretch finally smiled and looked up at him.
The vibrator against his lumbar spine sped up, the buzzing noise becoming louder. Sans whined and tensed his spine, trying to move unsuccessfully. The next moment, the one to the left of his sternum joined it. His whining grew louder as the vibrators shot pleasure through his bones, straight to his cock, which bobbed as his pelvis twitched.
He stared with watering sockets at Stretch, who only smiled back, apparently content to watch him squirm. Blue walked up, holding a mug, which he handed to his brother before turning to observe Sans, as well.
“I THOUGHT YOU WERE GOING TO PLAY WITH HIM,” he commented, lifting a brow bone. Stretch laughed.
“i will, but it’s fun to watch him play on his own, too.” Stretch replied. “he’s so cute.”
“HM,” was all Blue had to say to that as he continued to stand there. After a few more moments, he turned to Stretch.
“WOULD YOU MIND IF I…?” he gestured at Sans with a little smirk. Stretch let out another laugh and leaned back, sipping his drink.
“not at all, bro.”
Blue slipped off his gloves and set them aside before approaching Sans where he lay, helpless and panting. He also pet Sans like a dog as he settled on his knees next to him, but he kept it up, stroking down his face, testing his gag for any slack. After tightening it, very unnecessarily, he continued, testing the collar and the leather cuffs. Now that his attention, as shaky as it was, was drawn to them, Sans saw that they were made to look like dog paws, because of course they were.
He moaned his way through Blue testing all of the ropes and finding them satisfactory. Then he, with horrifying cheerfulness, tickled the underside of Sans’s feet, eliciting a series of yelps and broken laugher, until Sans thought he was going to pass out. That might have even been preferable, though he shuddered to think what they might do with his body in the meantime.
Instead, Blue reached down between his legs and grabbed onto the vibrator there. He began to pull it out, real slow, while Red groaned. His magic welcomed a break after being stretched for so long, and from the insistent, low vibration.
It was thrust back in roughly before being removed again. This time, when it was shoved back in, it was vibrating much more intensely. He yelped, prompting a chuckle from the couch. In broken thoughts, snatched from the moments Blue paused for a moment with the vibrator outside of him, Sans counted. Spine. Thrust. Ribs. Thrust. Ass. Thrust. Weren’t there four remotes?
He screamed as sharp, almost painful vibrations wracked him. The sensation was so strong he couldn’t tell where it was coming from. He was going to come right then and there. But he didn’t. Bewildered, Sans felt his body fail to release, the need to building up in his pelvis to join the painful pressure of the ring. Shit.
“Helllh!” Sans called out, eyelights snapping to where Blue was grinning at him. He had given up on moving the vibrator at some point, though Sans couldn’t pick the moment out, due to the torrent of sensations moving through his body.
“DID YOU TURN ON THE SOUL ONE, PAPY?” Blue asked, looking up at Stretch. Sans fought to understand his words. Soul?
“yep. Look at how much he likes it. that was a great idea, bro.”
Did he say soul? How had he been so distracted by everything else that he hadn’t felt something attached to his soul?
“Nnnnn,” he tried to express his unhappiness with this revelation when another wave of pleasure crashed through him, turning it into a loud, needy whine. Blue turned back to him and then looked down at his cock. It twitched, desperate to release.
“OH, I KNOW THE RING IS UNPLEASANT,” he punctuated the statement by swatting something soft against his cock. Sans winced, his magical flesh extra sensitive as it swelled with the need to cum. “BUT ONCE YOU’RE PROPERLY HOUSEBROKEN, YOU WON’T NEED TO WEAR IT.”
Sans dropped his eyelights down to his cock in time to see what Blue was using, only to see brown fur flick up and slap gently against his member. It was a tail, wasn’t it? He gasped as Blue did it a few more times, giggling.
“ARE YOU A LITTLE SENSITIVE?” Blue cooed at him, mocking. Sans tried not to squirm in response. He tried not to do anything, but nothing helped.
Blue shifted so that he was kneeling in front of Sans. With a wink, he leaned down and licked the tip of Sans’s cock. Sans gave a startled buck upwards. He really didn’t want Blue to do this, but at the same time...
For a while, Blue just licked at him, quick and teasing. Sans kept whining, right on the edge of not caring anymore that he shouldn’t want it. Suddenly, the other skeleton shifted onto his knees and elbows, and promptly took Sans fully into his mouth.
Sans’s hips thrust up as much as the bonds allowed, tears streaming down his face from desperation.
“Hnnnn...nnn!”
Blue’s tongue swirled around Sans’s cock while he tugged at the charm of the ring, pulling it against the base painfully. Sans squeezed his eyes shut, letting out a keening whine. For the first time of the evening, he was glad he couldn’t speak, or might have started begging. He just wanted to come. This felt too good and he just wanted it to be doing something, and god he wanted to come.
A shadow fell over Sans as Stretch stood just behind Blue, his pants unbuttoned and his expression lustful. He slowly walked forward. Sans’s whole body shuddered.
“you’re going to be a good boy, right?” Stretch asked as he began to fiddle with the rope holding Sans’s left leg bent.
Sans didn’t move. It wouldn’t work out to try to bolt now, would it? Maybe when they were finished with him he could try something.
The rope fell away, releasing his leg. When Sans didn’t struggle, Stretch reached across to his other leg, untying the rope there. Sans just let it slide to the floor too, staring up at the ceiling. As his legs stretched out to either side of Blue, his cock was released.
“READY TO PLAY, PAPY?” He asked.
That made Sans jolt. He scrunched both his legs up and attempted kicking himself away from them across the floor. Stretch caught his left leg, pulling it up sharply. Sans stopped kicking and let out a long whine. He sounded like a dog.
“bad dogs don't get to come,” Stretch warned as Blue climbed to his feet and stepped away.
Sans brought his free leg up anyway, bending it over his crotch in a very poor last attempt at modesty. He shivered in Stretch’s grasp.
His other leg was released as Stretch shifted to take Blue’s spot in front of him. Sans brought the other leg in to cover himself, too.
“look, he’s shy,” the taller skeleton said with an amused chuckle.
Sans just laid on his back, shaking. He wasn’t eager to be grabbed like that again, but as painful as the erection was, now that his cock wasn’t being stimulated directly, the rest of his situation was coming clearer again. They’d taken him in his sleep, tied him up like this...they were talking about keeping him as a pet. What was going to happen to him?
Stretch reached down and slipped the vibrator out of him, stopping to drag the tip around his anus before setting it aside. Sans’s hips gave a jerk at the touch. A breathy noise came out of him that was definitely not the kind of noise he wanted to be making.
“like that, hm?” Stretch asked. “then you’ll enjoy this.” He unzipped his pants, letting them drop slightly to reveal his long orange cock.
Sans went completely stiff. He didn’t know why it shocked him, but maybe somewhere in his head, he’d thought the brothers were just planning on playing around with him. Not this. This was definitely, absolutely, not okay. He kicked his legs out again, rapidly, wildly, lurching onto his stomach and scrabbling as fast as he could.
Stretch lunged forward and grabbed his leg again, pulling him back along the rough carpet. Sans flinched as his cock was rubbed on the floor.
“he really does need to be trained.”
Blue stepped in front of Sans and gave him a smack on the head with the newspaper.
“BAD DOG! STAY!”
Sans started fully sobbing, trying to curl up into a ball. His efforts were ignored as Stretch grabbed his pelvis with one hand. Sans could feel the tip of Stretch’s cock rub against his flesh. He gave another jerk, less to escape and more simply to express his panic. Garbled noises of fear came out of his stretched mouth, drool dripping down his chin.
Stretch slid into him easily, with a long, low groan.
Sans’s back arched at the intrusion. His cock gave another needy twinge, his eyes rolling up at the sensation of Stretch sliding into him, of being filled. When Stretch was all the way in, Sans shook his head, tears still dripping from his sockets. His shoulders trembled.
He knew it was useless, but he still attempted to speak, a “hwehhh wehhh” coming out instead of “Stretch, please.”
Sure enough, Stretch ignored him and began to slowly pull out before thrusting in again.
“Ha-anngh!”
At least this didn’t hurt. At least they weren’t hurting him, right?
Except for the aching erection, still stuck with the degrading dog toy around it.
“I’LL GO CLEAN UP BREAKFAST, YOU TWO HAVE FUN.” Blue turned to walk away.
“ngh.” Stretch seated himself fully inside Sans. He paused for a moment. “he’s still got a hole, bro, if you want.” Blue stopped and turned back.
Sans shook his head again. He tried wriggling his body, but all he managed was to flop like a dying fish on land.
Blue knelt down in front of Sans. “ONLY IF YOU DON’T MIND, PAPY. HE’S YOUR PRESENT.”
“go ahead,” Stretch said, and then started to thrust again. Blue lowered his pants, pulling out his cock, without wasting a moment. He had clearly enjoyed everything up to this point.
Sans looked at the cock, then at Blue’s face. He tried so hard to get out a ‘don’t make me,’ but it came out as comprehensible as the rest of his words.
“I KNOW IT’S HARD ADJUSTING TO A NEW HOUSEHOLD, RED, BUT YOU'LL GET USED TO IT.” Blue told him. “JUST HOLD STILL.”
Blue’s cock pressed into his mouth through the ring. Sans couldn’t do anything to prevent himself from tasting it. Moving his tongue only made him lick it, and trying to make more noise resulted in Blue’s cock giving pleasured twitches.
“MM, GOOD BOY,” Blue praised. Stretch picked up the pace, wrapping one hand around Sans’s cock and jerking. Sans yelled around the dick in his mouth, his legs kicking uselessly.
Both monsters continued to use him for their pleasure. Stretch gripped his pelvis, making sure to drive as deep as he could with every thrust. Blue set his hand on Sans’s head, moaning out encouragement as Sans was pressed forward onto his cock with each movement from Stretch.
Sans gave up. His body went slack, and he accepted the treatment with only some weak whimpers coming out of his throat.
“FEELS SO GOOD,” Blue groaned. He held Sans’s skull between his hands and went deeper, hitting the back of his mouth. Sans’s whimpers turned into choked, garbled sounds.
“yeah,” Stretch grunted. He began to pull on the ring, slowly sliding it down Sans’s cock.
Sans’s pelvis jerked involuntarily, but after that he held as still as he could. He shut his eyes. Just take it off just take it off…
“I- !” Was all the warning Sans got as Blue jerked his pelvis forward and came. Sans was startled into swallowing some before he started coughing and choking on it. Blue didn't take mercy on him, pressing deep into his mouth until he was spent. Finally, he pulled out, panting. Sans hacked some cum out through the hole in the gag, then gasped for air.
“OH, RED, YOU MADE ANOTHER MESS.” Blue scolded him as he pulled up his pants. “MAYBE WE SHOULD LEAVE THE RING ON…”
Sans looked up at Blue and shook his head back and forth rapidly.
“you’re so, mm, strict,” Stretch huffed. His thrusts became sharp and erratic. He slid the ring off in one motion at the same time he began to release inside Sans.
“Hnah...ahh...anhg…!”
Sans came in hard spurts, tingles running up his spine as he dissolved in bliss. For one second the situation wiped away, and he only felt divinely good as he kept coming onto the carpet and moaning.
Stretch pulled out with a hiss and let go of Sans’s pelvis. Sans landed on the floor twitching, still releasing cum.
“PAPY! JUST LOOK AT THIS MESS! IF YOU SPOIL HIM, HE’LL NEVER LEARN.”
“heh, there’s plenty of time, bro.” Stretch shifted behind Sans. Sans rolled the rest of the way onto his stomach and immediately regretted it, feeling his own cum sticking on him.
He was left undisturbed for a few minutes while the other skeletons moved around the room, Blue complaining about Stretch never cleaning up his messes.
Sans looked at them, then at the door. He inched toward it like a worm, trying to be as quiet as possible. He crinkled over wrapping paper that was strewn about, and his body froze. He looked over at the two again. Blue continued on to the kitchen, oblivious, but Stretch was watching him with narrowed sockets.
He stalked towards Sans, who cowered into a ball, shutting his eyes. Stretch grabbed him roughly by the collar and dragged him back to the space in front of the couch.
“guess sans was right. show the least bit of leniency and you think you can get away with anything.”
Sans shook his head, whining into the gag.
“no use begging now.” Stretch let go of Sans and bent down to unbuckle the gag. It probably wasn’t smart, but Sans spoke the second it came off, if for nothing else to see that he still had a voice.
“God fuck oh my god lemme go, lemme go, jesus what’d I ever do to you-”
“for starters, you have done your best to ruin christmas, and after sans put so much effort into making everything perfect. it's his favorite holiday, you know.” Stretch hissed out in low tones.
Sans’s face was shoved down into the already cool cum on the floor.
“the very least you could do is clean up your mess so he doesn't have to.”
Sans turned his head so his cheek was on the floor instead. The cum smeared along his mouth as he turned.
“Christm--what the fuck what the fuck are you-” He searched Stretch’s eyes for some sign that he was even the least bit sane. “What the fuck-”
Stretch was frowning at him, expression completely serious. It darkened as he spoke, and Stretch reached over to grab something, keeping one hand on his head.
“bad dog,” was all he said, and the rolled up newspaper landed on Sans’s sacrum sharply. Sans cried out, trying to shy away from the pain. Stretch cursed under his breath and increased the pressure on his head. Sans scrabbled his legs out behind him.
“No--stop, stop!”
“are you going to start behaving?”
Sans choked. “I just-” He gave in and sobbed once, his shoulders shaking, and the rest of his words came out thick. “I just wanna go home, please lemme go home, Stretch, come on, please, this is crazy. ”
Stretch knelt down and stroked Sans’s skull.
“this is your home now. blue and I will take very good care of you. there are just a few ground rules.”
“No...no! You’re nuts!” Sans lurched away, trying for escape again. Stretch yanked his collar, right back into the cum. Sans wriggled what he could of his body. “Don’t-!” He coughed at the taste of cum.
A series of blows landed all along his pelvis and femurs.
“Ahh!” Sans curled in from the pain, but that just made the cum rub over his face as it moved along the floor. “S-stop…”
“happily, once you clean up your mess.”
“You…” Sans didn’t even try to stop from crying anymore, words interrupted by ugly, blubbering sobs as tears spattered the carpet to mix with the cum. “You m-made me do this! You made me!”
“i’m waiting…” Stretch rubbed the newspaper along Sans’s legs. Sans flinched.
That was it. It didn’t matter if this was fair or not; it was happening.
Sans slowly turned his face to the floor and gave it a lick. He stayed frozen like that, shuddering.
“good boy,” Stretch’s tone wasn't any friendlier, but the newspaper moved away.
Sans wept into the carpet, licking at it between sobs.
“that’s a good boy,” Stretch continued to murmur while he went back to petting Sans. “be sure to get it all.”
Sans pressed his tongue into the floor, trying to make sure at least no more cum could be seen. Just let it be over.
Stretch started petting along his spine as Blue walked up.
“OH! YOU GOT HIM TO CLEAN IT UP!” He said, voice bright.
“yeah, i’ll take his training seriously, bro. sorry.” The hand on his back wiggled Sans slightly.
Sans stopped licking and curled into himself, hiccoughing between heaving breaths.
“You can’t d-do this to me…”
Blue laughed and pat him on the head before walking away again. Stretch pulled Sans up into his arms, cradling him on his back. Sans whimpered, but didn’t try struggling again.
“change is hard, red, but I think you’ll be very happy here. eventually.”
