Chapter Text

There was nothing like walking a snowy path early in the morning. The air was frigid and nipping at his bones. Cars were slowly moving by as he walked down the sidewalk, his orange eye lights watching each one pass by with careful nature, not wanting to slip off the road. The roads were quite slick because of the season but he could hear the faint sound of the gritter truck moving along the street. He paused to watch the large truck as it passed him by, the salty scent reached him slowly and he decided to finally move on to his destination. The tall skeleton didn't want to be late to meet up with his friend, that would be quite rude of him if he did.

Walking towards the upcoming shop he smiled, the smell of brew and baked goods filled the air as he stepped inside a quaint new coffee shop. He unraveled his scarf a little and glanced around the room looking for his friend. The shop looked rustic, the front where the cashier was, was painted black with all assortments of pastries on show behind glass. The menu behind the stand was written in white chalk, easy to read and it had doodles over it with examples of the beverages. The walls of the inside were bricks that matched perfectly with the black armchairs and dark oak tables that sat around. Not to mention there were ever present love hearts for a certain day. Valentine's day, the day he absolutely dreaded was tomorrow and he wouldn't even be able to spend it with anyone.

He shook his head slightly, getting his mind off the whole day entirely and kept looking for his friend. Once the tall skeleton spotted said friend he went to go sit down with a happy smile. They said their hellos and chatted about how cold it was before going up to order together and munching on breakfast sandwiches as they caught up back at their table.

When their drinks were near empty the orange eyed skeleton got a text, from his brother of course. He sighed as he read it and the other leaned back in the soft cushions of the armchair and asks, "is Sans doin' any oka'? ya look stressed from somethin’." His friend sounded concerned for his brother which made the taller relax slightly as he set down his phone on the table.

"He doesn't talk to me as much as he used to. The past few years around the holidays he just sort of.. clams up I guess? I think it's because of the death that happened at the mall but he won't admit it.." Sans had told him that the security guard had let them in and they wandered around for awhile and Sans went home early. He had found out the next morning of the guards death and it seemed to tear the smaller up.

"sounds terrible, 'm sorry he had ta go through that." The monster ate the rest of his food and tilted his head slightly, watching as Papyrus thought for a bit and trace little shapes on the table until he spoke again.

"Sans has actually gotten sick, again, his excess magic is making his bones slimey and it smells absolutely dreadful." Sighing he sipped on the last of his drink. "I made him go up to our family cabin for the week until it stops. He promised to call me tonight to check in, I can't imagine he's very comfortable up there all alone, but jeez, if you smelled it you'd know what I meant." Papyrus set his cup down and tapped his foot impatiently staring down his phone as he did.

The other chuckled lightly and waved off his worries, "’ave more faith in your brother Paps. i'm sure everything’ll turn out. tha’ sick huh?"

"Yes," his face scrunched up just thinking about it. "Sans does nothing to fix it either, just lets it ‘ride it course’, which if you ask me, is absolutely disgusting to clean up after. So I make him go to cabin, save my nose and my house." Papyrus glanced up to the other as he spoke quickly. He felt quite energized after the espresso he just had. Sighing and stretching out a little, Papyrus was feeling a bit cooped up on the chair, not being able to move around as he spoke.

It was nearly a godsend when his second favorite monster, Undyne, texted him and he replied back instantly to it. "Can we reschedule this for later? I'm sorry to just suddenly run out on you, but it’s important, I've been challenged to a cook off. The Great Papyrus never backs down from a challenge!" He exclaimed as he fixed his scarf once more.

The monster across from him shrugged and shooed him off. "o’ course, challenge is a challenge, I’ll tex’ ya to meet up again." His eyes stayed focused on Papyrus as he gathered his garbage and thanked the other for such a nice brunch. Papyrus racing out of there after throwing his trash away in the can. Hurried off towards Undyne's home, nearly slipping on the snowy path but he managed to catch himself and press on, as always. The other monster chuckled softly and rose from his own chair, time to do some shopping.

Sans' steps faltered as he walked up the wooden porch steps. The cabin had been passed down through his family and had always been in good shape. Papyrus and he both pitched in to keep the place intact for when they needed time away from each other. Looking back to the driveway, he noticed his car had made tracks in the snow leading to where he parked. He clutched his duffel bag to his chest nervously, he had stayed here many times before but had stopped staying alone all together after the Christmas incidents. He knew his brother wouldn't let him back into their house right now though, not when he smelled, "like a rotting skunk," as his brother had put it.

He shivered and then glanced to the sky, it was noon but he could remember the look on his brothers face when Sans woke up that morning; drooling in his sheets, clutching his pillow, his brother had cringed at the smell in the room. Sans had some relief when he left knowing his brother wasn’t aware of why he was in such a state.

The skeleton dug around in his sweater pocket and shakily brought a key to the doorknob, unlocking it and listening as the creaking old door opened. He found himself standing inside the cozy log cabin, that had only one bedroom and a bathroom. Sighing he closed the door, slumping back against it as a shudder made its way through his body. He dropped his duffel bag on the cold hardwood floor and shut his eyes taking in deep, calming breaths, fisting the key in the palm of his hand.

The cabin smelled clean, familiar, like pine and cider. His brother always cleaned the place after every visit. He cleared his head with the familiarity of the fresh scents, then shook it slightly as he made his way to the table in the kitchen. He set the key down and went to see what they had left over in the fridge.

Papyrus had stayed here last, of course, not even two weeks ago with god knows who. The fridge was sort of bare but he had expected that. Going shopping for food had been uncomfortable enough with the looks he was given as he was in early sub heat. Sans decided to make the few trips in and out of the small cabin, bringing in groceries after turning on the lights in the kitchen and family room.

The small skeleton put all the perishable foods away and left everything else out on the counter, the chore becoming to much in his state even if he wasn't a lazy bones. He eyes a box of cheez-it, snatching it up he wandered to the couch and opened up the box. Pulling out his phone from the shorts he was wearing and texted Papyrus that he had made it safely. He turned his phone off and set it to the side afterwards to snack on his prize, before easing into a small nap.

It was around a hour and a half later when Sans awoke from the feeling of burning up. He stripped out of his sweater and made his way into the bedroom, dragging along his bag, setting it on the dresser. His sweater had been left on the ground next to the bed, as he flopped down on top. The bedroom had light oak walls and the same hardwood floor as the rest of the house, the furniture and bed were made out of the same walnut wood and the bed was sturdy and had to weigh about a hundred pounds itself.

Sans nuzzled into the soft duvet, feeling up the blanket that was folded next to his face. He cracked an eye open staring at the pillow, licking his broad teeth as he managed to shimmy out of the rest of his clothes, leaving only the present from R on. He had kept it, surprising himself, but it was helping with his heat. It felt as if he wore nothing but it also kept him feeling secure in a way, lightly he traced over the lace and blushed at matching blue at the feeling against his bones. Giving in he ended up grabbing the pillow and moved it between his femurs, slowly starting to rock on it.

Groaning in relief at the touch to his burning magic, he pushed down into the soft, fluffy material. The lace being pushed into his soaked folds was a stimulation he enjoyed, until he realized that he had felt it before. Thick boney fingers pressing against the lace, rubbing over his wet lips through the material. Sans startled slightly at the flash of red eyes in his mind and groaned. “damn it!” Trying again he cleared his head, rubbing up against the pillow again, moving one hand down to rub at his clit harshly, needing to get relief.

He began to pick up the pace, thrusting harder than before, the stimulation not getting him anywhere, just making him need more. He needed to be filled, he lowered his head down and moved his other hand to his folds, thrusting in three fingers at once. It wasn’t enough, it wasn't like having the thick red cock inside him, scraping along his walls with a perfect fit. Screaming he shoved his face into the pillow, tears dripping down his face slowly as the pain became stronger with every thrust, and every stray thought.

Pulling the pillow out, he raised his hips and pinched his clit harshly, the three fingers still thrusting deeply inside. He couldn't get off, Large fingers teasing him wider, curling into the bundle of nerves perfectly, A voice whispering next to his skull, “yer doin’ so good for me sansy.” stretching him wider and putting a slight pressure on his clit. His dreams merging with the actual events, he was hornier than ever but he didn't have what he needed to finish himself off. He sobbed, this is going to be a long heat if he can't get himself off at all. Red eyes and sharp teeth smirking at him, “yer mine sansy, only mine.” The growl sent shivers up Sans’ spine even now.

--

The large monster had managed to drive to the cabin that evening, following the signal he had in his car that tracked his little mate’s phone. It was quite a ways out but the smaller was worth any trip and there was a lot of privacy out here. He felt wound up as he imagined his mate all alone, not to mention in heat. He knew for certain he would spoil the pretty little skeleton, especially with it being Valentine's day. He had quite a few things in the trunk of his car for the occasion, most were clothes for himself and some snacks he though Sans might like.

Was he obsessed with the smaller? He could laugh at that, this had gone way past obsessions by now. He wasn't obsessed with those blue eyes, or those small smooth bones, nor even the pretty magic he showed. No he wasn't obsessed. He was in fucking love with Sans, completely head over heels. He planned to show it in any way he could, be it murder, sex, or food, however the little one wanted him too, he would do it.

With that thought in mind the monster turned down an unpaved driveway, going all the way down. His headlights were on as it was getting dark fairly early. Red eye lights glanced at the muddy tire tracks in the snow before him, slightly filled in with the fresh dusting of snow. His little pet had been here for a few hours, enough to make him more needy and more willing for stimulation. That ever present smirk widened slightly, finally pulling up behind the others car, placing his own in park as he scanned the area. Seeing nothing alarming, he climbed out and began into walk the perimeter of the cabin, making sure no one was around and that there were no traps or cameras in the area.

Deeming it free and clear, he made his way back to the car to unload his bags to the porch in one trip, leaving the door unlocked as they were in the middle of nowhere. The large monster made his way up the slippery steps and to the door finding it to be unlocked. He snorted and opened the door, stepping inside to the rather cold cabin dropping his bags by the door. Listening closely he could hear the echoes of whining coming from the bedroom and smiled, closing the door he spoke quietly, “must ‘ave been expectin’ me.” The large monster locked the door and walked towards the bedroom door, pulling off his coat and leaving it on the back of the couch.

The large monster approached the bedroom door and leaned in for a moment, he heard a sobbing moan and he groaned deeply in response, head hitting the door softly he felt his magic respond. “fuck, all ready fer me.” Reaching up he pushed open the door and the sight was both alarming and arousing at the same time.

Sans’ pelvis up in the air facing the door, three fingers deep in his dripping blue cunt, the lacey thong pushed to the side, his other hand braced on the headboard as Sans cried out, “please please please, fuck I need to cum, please let me cum.” tears pouring down his face, the large monster could see he was struggling.

The big monster approached slowly, dropping his pants and kicking them off, his fully erect cock sprung from it’s prison and he groaned. “come on precious, cum fer me.” Red eyes let out a deep rumble from behind the small skeleton, merely a foot away from the bed. He watched the others face as the SansUNDERTALE™ gasped out, eyes scrunched shut, still completely unaware of the intruder that was in the room.

Sans was so close, the voice echoing through his head, but it sounds so real, telling him to cum for him. He pulled his fingers out and harshly thrust them into the lace and dragged over his clit, with a scream he finally came. It was a weak climax and he began to sob, he got no relief from it, he wished the other monster was here. “p-please, you need to fuck me, please fill me up. i need you!” Sans couldn’t help crying out, he hoped that the other knew he was in heat because he realised he could not get through this one without him.

The large monster moaned at the begging the other was doing, he licked his teeth, hungry for his little mate. He knelt down carefully, sharp fingers hooking into the lace and tearing a hole through it as quietly as possible. Leaning close he breathed deep, inhaling the most beautiful scent he has ever smelt and chuckling internally when remembering his brothers description. Then without pause shoved his broad tongue deep into Sans magic and flicked his thumb over the still lace covered nub, giving him a little relief from the strain he has clearly gone through.

The hand Sans used to play with himself shot down to grasp the mattress as his other hand gripped tighter onto the headboard, he let out a loud pleasured scream at the sudden intrusion. Building up quickly, now with real stimulation and the tingle of magic touching magic, Sans came again quickly, moaning loudly and muttering curses. Once the tremors stopped ripping through him he collapsed into the mattress face first and took in a deep steadying breath before peaking one eye out to look directly into the eye lights of his captor? Rapist? Lover? He wasn’t sure anymore.

The larger looked into those hazy white eye lights and smiled gently at the smaller, with blue excess dripping down his chin. “heya sansy, thought ya could use a han’.” He licked his teeth clean, red glowing tongue swiping those sharp fangs and teasing the smaller at the sight. He watched as Sans shuddered, not sure if it was at the sight, his voice or just aftershocks of his intense orgasm.

The smaller carefully moved to lay on his side while coming down from the high, keeping his eyes focused on the monster grinning at him. “how'd you find me?” Sans pondered in a mumble gulping a little as the monster made his way onto the bed. He still looked weary of the skeleton looming over him.

“sweetheart, i ‘ave my ways. ya shoul’ know better than ta keep yerself cooped up in such a state when ya got me ‘ere ta take care o’ ya.” he wrapped his arms around the blue eyed skeleton who jumped slightly at the touch, ending up only to sigh, melting into his arms as he massaged down Sans’ spinal cartridge moving down towards the lower lumbar.

Sans nuzzled into the fabric of the man’s undershirt and sighed, “i should have realised you would find out, but it’s not like i can just call you. you didn't exactly leave your phone number.” Sans chuckled softly at the thought of being raped and then finding the rapist phone number listed in his phone contacts under Naughty Santa. How would someone logically react to something like that, clearly not beg for them to help fuck ‘em through a heat, that's for sure.

“oh? did ya want mah number sansy?” kissing the top of Sans’ skull and shifting a bit awkwardly as he was still painfully hard. He kept himself at bay for now because for once the other was really trying to converse with him, instead of escaping him. His chest rumbled softly at the thought of Sans calling him over, to hang out or for a quick fuck, it was a pleasing thought. “i’ll give it ta ya when we’re done.”

His hands teased down lower on the other, feeling the lacey fabric on their pelvis he couldn't help the small laugh that left him, “ya really like them lacey thin’s don’ ya. wearin’ one the firs’ time and now wearin’ the one I got ya. i’s a good look.” The rumbling grew louder as Sans hid his face in the monster's undershirt. His arms tightened around his mate, waiting for the smaller to talk.

Taking a deep breath, the blue eyed skeleton got the courage to speak. “The first time was for a dare. I-I'm only wearing these because.. because of the heat.” voice trailing off as ‘R’ rolled onto his back, moving Sans to lay on his ribs.

The red girth was pressed up against the slick opening that Sans’ heat had made in preparation. He grinned lazily watching the other stutter and slightly wiggle his hips back onto the member. The Red could feel the juices from his little mate, sliding over his length, lubing him up in his squirming. A small grunt of arousal passing his teeth as he stared at the others flushed face, closing in and licking gently over his blunt teeth, kissing softly and easing the smaller into a sweet and tender kiss.

Sans readily accepted the large tongue into his mouth, intertwining it with his own shorter one. Moaning into the kiss, he ground his hips down softly and started to whine, “please, help. please, please fuck me,” his heat building back up deep in his core. Remembering his fail at riding him the first time he whimpered softly, “sorry i can't ride you. i'm not good at this.”

“i's ‘aight sweetheart, ya jus’ worry ‘bout how yer gonna walk afta this.” A soft rumbling purr was ripped from Sans at that making the other purroud. He placed a few more kisses on Sans’ blushing face, moving around once again to have his mate laying under him. “yer so perfect, sansy. der's no one in da whole world who shines brighter than ya.” he kissed his precious boy as he spoke, leaving the other breathless and panting at the praise.

Sans began to get more heated with every kiss, thrusting up to the others pelvis, trying to get some friction. He started to whine into the kisses and gripped the larger monster ribs through his shirt, panting, he started to caress the bone beneath his hands, feeling how the other was built. This was new territory and he was going to explore it, but he was getting a bit desperate and decided to lick along the collar bone to speed things along. Biting down around the bone, he gave a small suck before releasing and licking the small indents.

The larger monster keened under the attention to his bones, hips stuttering above the other and groaned, “a’ight sweetheart, le’s do dis.” Leaning down to nuzzle Sans’ neck he lined up his cock with the slick waiting entrance, slowly easing himself into the opening. Moaning he as managed to slide all the way to the hilt without any resistance, “see sansy, ya were made jus’ fer me. perfec’ fit.” He remained seated for a moment because no matter how easy the fit, it’s better to be prepared.

He enjoyed be this close to his mate. Being surrounded by him was something the larger would never be tired of. The pleasurable face Sans made was more than enough to get him moving, loving how he was being touched by his little lover with want instead of the usual rejection he was used to getting. He could see himself with this skeleton forever, he just hoped the little skeleton could love him too.

After a moment to settle, he noticed his little pet start to squirm, thrusting his hips up, moaning softly. The small voice whining out to him, “move sir, please.” the little one groaned and if the larger was having trouble restraining himself before, hearing the small needy whines definitely made it hard to hold back now. Grunting slightly he pulled back and then thrust back in harshly to gauge the others reaction.

Sans was getting impatient, but as soon as the member tried to pulled back immediately regretting his decision for movement, whining more until it slammed back home and he moaned openly. Every time bringing the same reaction until Sans was tearing up and gasping a sting of loud moans, gripping the largers’ ribs tightly as he whined out, “more sir, please harder.”

‘R’ got the message loud and very persuasively, eagerly picking up his rhythm. Pulling one leg to wrap around his pelvis and the other pushed up against Sans’ ribs, he start hitting deeper and faster. The moans only got louder and the string of needy whispered curses were making his mind blank in need to help his little mate. R glanced down watching as his thick red cock slid in and out of the drenched blue folds, groaning at the sight of his now purple cock sliding in and out of the others magic, his movement faltered and his thrust hit sharper than normal. Sans screamed out momentarily, gasping he looked to see if he hurt his pet, only to hear the scream die down into a repeated muttering of, “again, please again~.”

They were both seeing stars now the larger monster was plowing into him with an eager sharpness, both panting moaning messes, the slick magic coating sans, surrounding the larger in that intoxicating scent, (yeah screw Papyrus’s opinion) R was in absolute heaven and he was never leaving this monster again. Sans’ walls began to flutter around him, pulling deeper, Sans was close again, but he wanted to drag this out some more. Pulling out fully he grabbed the small whining skeleton and flipped him over to plant his face into the mattress and pelvis on display. Holding Sans there for a moment to enjoy the glistening purple view that was wiggling in his face, chuckling softly. “hold on tight sansy.”

Before Sans could react the large monster leaned over him, completely enveloping him in his size, then thrust in harshly. Sans scrambled and caught hold of the head board tightly, “fuck!” he shouted in bliss, giving a fully body shiver at being completely surrounded by the monster. This monster that has never harmed him, and never actually come after him with ill intention, just cared for him, teased him and fucked him really good twice. He let out a wanton moan and tried to thrust back into the other, but he couldn’t keep up to the pace and power of R. He was close, so close it was intoxicating, so close he coul…. His clit was pressed and he screamed his release clamping down on the thick girth seated inside, the large monster still stroking his clit through his orgasm.

R smiled, panting, he stilled once the others walls convulsed around him, holding him in place, he waited patiently for the other to come back down before he rumbled his chest on the others spine and began to thrust harshly again. The moans that were escaping his small lover were enough to push him on, one hand caressing his spine moved up and grabbed the back of the smallers’ neck holding him down, the other hand gripping his pelvis, pulling it back roughly with every thrust. “ya like tha’ sansy, like when i pin ya down an’ fuck ya from behin’. ya like when im rough with ya.” they weren’t real questions but he felt the smaller nod along with them and keen below him, his purr stuttering under his moans.

Sans gasped when a very sensitive bundle of nerves was pressed into and cried out, “Rr-! Rrrrrr.” wanting to call out his lovers name.

This however, made the monster frown, thinking his good boy was growling at him, so he pressed his weight into the small skeleton and growled back. “yer tryin’ ta stop me?”

Sans shook his head panting heavily, “..nh..name..” he all but mewled out, hands tightening on the headboard.

R’s deep chuckles slowly shifted into a pleased purr. “m’names red sweetheart.. say it. say my name.” When he finally does, it came out soft and sweet. Sans started to chant his name over and over quietly, riling him up further. Red slammed into the little cunt. “ f-fuck...yea, that’s it love, louder! let everyone know yer mine!”

Through the torturing pace Red set, he felt himself getting close and growled near Sans skull, “ya ready ta cum again for me.” another nod and a groan sounded out. The larger purred and smirked, “good boi sansy. we’re gunna cum together when i tell ya, got it?” another moan and a sharp nod, he leaned down, replacing the hand on Sans’ neck with his tongue as he licked along the bone softly when his mark was starting to show more with every time he left it. Groaning loudly he muttered, “cum for me sansy.” Before he moaned deeply, sinking his teeth into the mark once again and seating himself inside the smaller skeleton. As his first rope of hot cum hit Sans’ walls and he felt the smaller monster’s walls clamp down and milk him for all he had, he gave it up willingly.

After he had no more cum to give he pulled out his dick and watched the mixed juices pour out in a thick purple ooze, running down quivering femurs. Quickly he grabbed his small mate and pulled him into be the little spoon, caressing and kissing him gently he smiled, “i gotcha sansy i gotcha, ya just res’.” He let his rumbling purr vibrate through the worn out body, coaxing him to sleep. Red sighed and glanced at the time, a little past 1am, they had been at it for at least five hours already.

Once the smaller was deeply asleep he got up to grab some supplies for his little needy mate, for when he wakes up again. Grabbing some water bottles, some fruit and a couple granola bars he made his way back to bed, placing them on the nightstand. He climbed in, wrapping around his little mate, pulling the blanket up and falling into a quick sleep, knowing he needed to get as much as he could when he could.
