Kinktober 2019: Day Eleven

Pairing: Horrorcest (BloodSugar)

Featured Kinks: Anal Pounding, Anonymous Sex

Additional Warnings: Sex Toys, Light Spanking, Rough Sex, Creampie

----------

Papyrus regularly threw anonymous hookup parties exclusively for the monster community, and the parties always drew a massive crowd of both regulars and newcomers looking to unwind with no strings attached. This party topped all of its predecessors though. Papyrus had rented out an entire club venue, letting the thumping bass of the music and the strobing colored lights assist the monsters in attendance in keeping their identities a secret.

Blood, who once called an alternate universe known as Horrortale his home, never would've considered himself a party guy, but with sexual tensions at home rising to levels that even a skeleton with no lungs would consider suffocating, he decided to give an anonymous sexual encounter a try. Thankfully, Papyrus prepared his sensual soirees for all levels of experience with small cards bearing instructions laid out right at the entrance.

WELCOME TO THE GREAT PAPYRUS' EQUALLY GREAT ANONYMOUS SEX PARTY, the card read in embossed, gold-leaf capital letters. PLEASE HELP YOURSELF TO A CONVENIENTLY PLACED MASK OR GLOVES IF NECESSARY TO PROTECT YOUR IDENTITY! 

Blood checked the display of masks, choosing one that would hide the hole in his skull. An injury like that would be a dead giveaway if anyone here knew him. Blood's single working eyelight returned to the instructions on the card.

CONSENT IS VERY COOL, SO RESPECT YOUR PARTNER(S)'S BOUNDARIES. NO HUMANS, CHILDREN, OR CONVENIENTLY SHAPED LAMPS ALLOWED UNDER PENALTY OF ETERNAL BANISHMENT!

The levity of the message helped Blood to relax, and he passed through the entrance alcove into the main area of the club with an eager smile on his skull. The heavy bass of the music thrummed through his bones, stirring his magic. It took a moment for his vision to adjust to the dynamic lighting, but once it did, Blood liked what he saw.

Monsters grouped together on strategically placed couches or in shadowy corners in pairs or threesomes, and Blood even spotted a densely packed crowd having what appeared to be an orgy on the dance floor. Small tables dotted the venue with offerings of food, drinks, and sex toys. The scent of sweat and arousal drifted to Blood's nasal cavity as he made his way deeper into the club in search of a partner. He wanted something specific- a Papyrus-type, if he could find one.

Blood prowled through the club, bypassing interested monsters without sparing them a glance. He wanted what he wanted, and he pursued his intended quarry with a singular purpose. He caught glimpses of a tall, slender skeleton that fit his tastes, and the hunt began. The thrill of the chase awakened a hunger in Blood that had nothing to do with food.

Passing the dance floor orgy, Blood spotted his target again. The skeleton made sure they had his attention, then slowly unbuttoned the top of their sexy nurse costume, putting a pair of small   breasts with erect nipples on enticing display. Blood let out a low growl as another group of monsters passed in front of him, blocking his line of sight. By the time his path cleared, the other skeleton had vanished into the sectioned off seating areas in the back of the club.

Blood followed, letting his instincts lead him to the shadowed booths with their plush couches and low tables littered with condoms and sex toys. Blood heard movement; the other skeleton must be back here. The chase neared its end, and Blood's magic throbbed in anticipation of finally capturing his prize.

There.

Blood stepped around a partition and found his prey. The skeleton was bent over the arm of a couch, skirt flipped up, underwear conspicuously absent, and fingers sliding up and down their slick entrance before dipping inside their eager hole. Their other hand worked a dildo in and out of their asshole with practiced strokes. Blood's mouth watered, and his magic swelled, surging against his self control. With the colored lights strobing against the shadows, he could easily imagine this skeleton's ecto-flesh to be his brother's soft coral shade.

Blood let the fantasy consume him.

Positioning himself behind his pretend brother, Blood slapped the firm, curved ecto-flesh before him, then grabbed double handfuls to knead under his greedy phalanges. The sex toy fell from the other skeleton’s hand to be lost to the shadows, and they tilted their hips to encourage Blood to take what he wanted. Blood let his sockets close briefly, imagining different surroundings and his brother’s voice begging to be taken. His cock ached for coral colored ecto-pussy, but this would suffice. 

Blood let his basketball shorts drop to his patellae, smacking the ass again and causing the other skeleton to squirm in pleasure while he palmed his own dark red magic with his other hand. His shaft throbbed, pre-cum oozing from the tip to be smeared along the length for lubrication. Blood didn't have the patience to go slowly, not with a skeleton so similar to his brother bent over and spread open in front of him. 

Blood rubbed the head of his cock against the other skeleton’s pussy lips, using it to part the arousal-slicked folds and nudge at the treasure inside. He watched the other skeleton’s phalanges dig into the fabric of the sofa, and though the music from well-hidden speakers drowned out their voice, his mind easily added a soundtrack of moans and mewls that his own brother might make. 

Spurred on by his thoughts, Blood sank into the wet heat, savoring the way the tight walls dragged against his cock as he forced his way deeper without waiting for his partner to adjust. He couldn't hold himself back; it felt so right, so perfect, exactly the way he imagined Sugar's pussy would feel gripping his cock.

The other skeleton shuddered at Blood's rough penetration, but Blood was rapidly losing his grip on coherent thought. He pulled back for a thrust, and the friction made him growl with pleasure. He wanted more! Blood braced his brother with a bruising hold on each hip and slammed forward. His brother moaned, his whole body vibrating with excitement.

Blood set a savage pace, lost in thoughts of his brother, lost in the desire to pump harder, to go deeper. He wanted to claim his brother’s pussy; he wanted to destroy it, and leave the taller skeleton a dazed slobbering mess beneath him. The more he thrusted, the more magic surged to his cock, thickening and lengthening the already engorged shaft. His thin control was slipping, and in a brief moment of clarity, he worried that he might hurt this skeleton in his fervor.

He should slow down.

He couldn’t slow down.

He was close, so close.

Sugar's pussy stretched to its limit; Blood could feel the slick walls struggling to contain him as his cock dragged and pulled at them. Suddenly, his brother’s spine arched, and his gorgeous body stiffened. Blood's hips bucked into the movement just in time for his cock to be squeezed deliciously by his brother’s orgasm. 

Blood could hear the other skeleton crying out in ecstasy over the blasting music. One final thrust hilted his cock in the fluttering pussy, and he roared, filling his partner with thick ropes of scarlet cum. 

The orgasm did nothing to diminish Blood's lust. He wanted more. His shaft throbbed painfully, milked dry by his brother’s pussy clamping down on it over and over yet still left rock hard and ready for more by Blood’s pent up sexual frustration.

Apparently Sugar felt the same way because he reached back, grabbing his ass cheeks and spreading them apart to reveal a new hole for Blood to wreck, the rim still glistening with leftover lube from the dildo earlier. Blood heard his partner pleading, but the music drowned out the specific words. He imagined his brother begging him to fuck his asshole instead. His overabundant magic surged again, and his already fragile control crumbled. 

Red eyelight blazing, Blood lined himself up. His body burned with a heady mix of magic and desire. Punctuating his every movement with feral growling, Blood shoved his way into his brother’s tight asshole. The entrance dragged at him, fighting every thick inch of his cock and creating maddening friction that only drove him to seek out more of it. He could barely pull back to thrust because his brother’s walls held him so tightly, but he managed.

Panting and drooling, Blood began snapping his hips forward. At first, Sugar tried to push back on the forward thrust, but he soon gave up in favor of letting the waves of pleasure wash over him. Blood's pelvis pounded into his brother’s ass each time he hilted himself, the force hard enough to bruise. The bolts securing the couch to the floor rattled as Blood's powerful thrusts loosened them. Sugar could only hang on for the ride.

Blood leaned forward, adjusting his grip by wrapping his arms around his brother’s waist. The new position, bent over his partner's body, allowed him to get even deeper into the other skeleton’s hot, tight asshole. Blood could feel his brother trembling beneath him and hear the barely coherent praises being screamed despite the music, and it silenced the nagging worries that he might harm his brother in his uncontrolled state.

With another orgasm fast approaching, Blood began rolling his hips, focusing on long, strong movements to eke out every bit of friction he could get. His growls turned into huffs and whimpers, and his body ached for the next release. Somewhere in his foggy mind, an inner voice reminded him to tend to Sugar's pleasure as well. Turning his skull, he spotted a wand-style vibrator on a low table off the side. He snatched it up quickly as his pace stuttered. Switching it to the highest setting, he reached down and touched it to Sugar's neglected clit at the same moment he buried himself deep in Sugar's abused asshole.

Sugar stiffened and squirted all over Blood's basketball shorts, staining them and his own ecto-thighs with their mixed fluids. The movement squeezed Blood's cock, and it pulsed, emptying a hot load of cum deep inside of his brother. Finally satisfied, Blood's cock dissipated, leaving the other skeleton with both their ass and pussy twitching and overflowing with cum.

With his excess magic spent, Blood returned to his senses. He gently helped his partner settle into a more comfortable position on the couch. Small spasms wracked the taller skeleton's body in the aftermath of their powerful orgasms, but they gave Blood a thumbs up to show that they were alright. Still concerned, Blood pantomimed fetching some water, and his partner nodded.

Yanking his soaked basketball shorts up, Blood found his way over to one of the snack and beverage stations where he collected a bottle of water and a variety of snacks for his partner. It made him uncomfortable to think of any monster expending so much energy without food to refuel, especially one that resembled his brother. He shoved a protein bar into his own mouth as he walked, but he kept most of his haul for the other skeleton.

The couch was empty when he returned. After a brief search, Blood concluded that the other skeleton must have left. It was probably for the best. Blood wanted to avoid awkward questions by being home when his real brother returned from his book club; seeing his stand-in brother basking in the afterglow of a thorough pounding would have tempted him into an encore performance. 

Leaving the snacks and water in case the other skeleton came back looking for them, Blood teleported home and collapsed onto his mattress, exhausted but satisfied. 

He couldn’t wait for Papyrus' next party.

----------

Sugar breathed a sigh of relief when he stepped through the door into an empty living room. Thank the stars, his brother must be upstairs sleeping, the lazy bones. He hated lying to his brother, and making up details about a book club that didn’t exist was difficult. With his brother out of sight, he wouldn’t have to worry about his stilted gait raising brow bones. He wouldn’t need to make a mad dash to the shower before the scent of sweat and sex on him attracted Blood’s attention or risk more cum dribbling down his ecto where his brother would surely see it.

As much as he hated sneaking around, Sugar really couldn't wait for Papyrus' next party.

“O-oh my, d-darling! Who k-knew you were this skilled with your m-mouth?”  Mettaton’s voice malfunctions as he moans, his speakers crackling as you suck on his clit.

Kinktober 2019: Day Ten

Pairing: UT!Sans x UL!Sans (ClassicLust)

Featured Kinks: Bondage, Frottage, Cock Worship

Additional Warnings: Oral Sex, Hand Job, Mild Orgasm Denial

----------

Sans agreed to try bondage for the first time without much coaxing. Being tied up meant not having to move, right, and not having to move was the laidback skeleton’s favorite activity, especially during sex. He just wanted to lounge and let his partner pleasure him, and hooking up with the Sans from Underlust guaranteed 100% satisfaction on all pleasure transactions. Those Lust monsters were the Energizer bunnies of producing orgasms. They just kept going and going and going…

Actual bondage differed from what Sans imagined though. Lust wouldn’t be satisfied with some simple handcuffs attaching his lover’s wrists to the bedposts. Instead, the flamboyant monster arrived at the hotel room they’d rented in his universe (the innkeeper charged an hourly rate, and nobody asked questions) with a box full of cuffs, straps, ropes of various materials and thickness, gags, chains, blindfolds, spreader bars, and equipment that made Sans question his entire foray into this universe. 

“don’t worry; we’re only going to use the things you feel comfortable with,” reassured Lust, possibly responding to his counterpart’s nervous shuffling, or perhaps he gave the same disclaimer to every monster he brought here. “we’ll discuss some safewords too in case you’re unsure, uncomfortable, or want to stop. using ‘blue’ for ‘stop’ is pretty common.”

Sans nodded mutely, still taking in the bondage equipment spread out before him. "sounds good." Guess we’re really doing this, he thought, removing clothing items and discarding them haphazardly on his way to the bed.

Lust dug around in his treasure chest of bondage equipment while Sans got himself situated, finally fishing out two sets of conjoined padded cuffs with an adjustable strap connecting them. He set them on the floor and grabbed a spreader bar, holding it up speculatively in front of his Classic counterpart. Satisfied with his choice of equipment, Lust strolled over to the bed, still fully dressed, to peruse Sans’ naked body.

With a wicked grin that sent a delicious shiver up Sans' spine, Lust laid down the tools of his erotic trade. “get on your knees,” he instructed, then got to work securing the bindings.

First, Lust positioned Sans' arms behind his back, fastening the lined cuffs to his wrists firmly but not painfully. The matching ankle cuffs went on next, and Lust double-checked the fit a final time before adjusting the strap that linked the two sets of restraints. Finally, he nestled the ends of the spreader bar against Sans’ femurs just above his already trembling patellae, effectively immobilizing him while leaving him open for a bevy of pleasurable activities.

Sans shifted, testing the bindings. He definitely couldn’t move unless he tried rolling, but he had no desire to spend his sexy time face down on a hotel room floor. It truly hit him in that moment that these cuffs and straps left him completely at Lust’s mercy, relying on a single syllable soundwave as his only means of affecting the situation. He wouldn’t be able to touch himself; Lust would dole out, or even withhold, the orgasms as he saw fit. The lack of control thrilled Sans, and his magic began to pool in his pelvis.

Naturally, he cracked a joke to ease the tension. “now that i’m hog-tied, are you going to slip me your sausage?”

Lust chuckled, low and sultry, removing his clothes and laying them neatly on the bondage box before answering. “actually, you’re going to form a nice ecto-cock, and if you perform well, i might even let you pork me.” 

The Lustverse skeleton reached out with deft phalanges and stroked his Classic counterpart’s pubic symphysis, coaxing the rich blue magic into thick, hard cock. With the other hand, he swirled his own magic into plump pussy lips, already glossy with arousal. San groaned and tried to lean forward, but he couldn’t gain any momentum without free use of his limbs.

“lay back and relax,” purred Lust, placing a hand on Sans’ sternum and carefully pushing him backwards against the plush hotel pillows, “we’re gonna have a great time.”

Translucent purple ecto-flesh enveloped Lust’s bones, and every inch of that ecto-flesh rubbed against Sans’ needy cock when Lust backed up until his face leered at Sans from between his femurs. Sans gasped as a slender hand wrapped around the base of his cock, but he couldn’t thrust into it like he wanted to. Why had he agreed to be tied up?

“such a big, thick cock,” Lust moaned, rubbing his cheekbone against it and letting a bead of blue pre-cum streak across his face. Slowly, much too slowly, he stroked the entire throbbing length with one hand, then leaned in, kissing it softly from base to tip before letting his tongue dart out and catch a second drop of pre-cum. “mmm, so good.”

“f-faster.” Lust’s touch and his voice heightened Sans’ desire, but the speed at which he moved his hand only frustrated the bound skeleton. He needed more, but Lust was clearly in no hurry.

Letting more lewd gasps escape his mouth, Lust arched his back and rubbed his breasts against Sans’ cock then lowered his head and ran his tongue along the shaft, swirling it around the tip. “yes, so hot… you’re making me so horny…”

“do something… please,” whimpered Sans who wanted nothing more than to grab his cock and jerk it hard and fast until he came all over those perky purple tits. He couldn’t take all of this teasing, all of the gentle not-enough touches.

Lust pouted, putting a single phalange to his mouth in feigned innocent confusion. “is this what you want?” he asked in a lilting voice. Lust straddled Sans, holding himself above the other skeleton’s cock so that Sans could see the slick arousal on his pussy lips and thighs. ‘you want my tight, wet pussy on your thick, throbbing cock?”

“yes!” Sans’ frustration and desire combined into an unbearable need, the tension building and building with no release in sight, unless Lust would. Just. Cooperate.

Lust lowered himself, still in no hurry despite the fact that he could see Sans straining against his cuffs. Soft purple pussy lips cradled the dark blue shaft between them, Lust’s pulsating opening giving Sans’ cock a sloppy kiss. Lust’s breasts bounced as he rocked his hips, grinding his slick wet pussy along his counterpart’s aching length. He tilted his skull back, let his sockets close, and emitted the most lewd moans he could muster.

Pleasure built; Lust rubbed himself on Sans faster and faster, panting with his purple tongue flopping out his mouth. Sans just wanted to thrust, to sink his cock to the hilt in that tight little hole. He just wanted fuck Lust until the other skeleton couldn’t move. The tension and building pressure were too much. He couldn’t take it.

Without warning, Lust dismounted, standing on his knees between Sans’ femurs. In the same smooth motion, he took the swollen shaft in his hand, squeezed firmly, and began stroking it hard and fast, his hand sliding easily up and down the length now soaked by his own juices. Sans groaned and panted in response, bucking into Lust’s hand as well as he could. 

Pleasure ignited Sans’ entire body like wildfire in his magic, and cum exploded from his cock like a fountain, splattering across Lust’s face, tits, and stomach.

Sans basked in the euphoria of an amazing orgasm, surveying his handiwork. “my work here is done.” He expected a quick chuckle before Lust untied him, perhaps a response to his meme joke.

The seductive, mischievous smile never left Lust’s face. “oh, we’re only getting started.”

The monsters of Underlust were the Energizer bunnies of producing orgasms, after all. They just kept going and going…

Thankfully the hotel charged by the hour, not by the orgasm.

“Are you sure about this?” Sans asked, hovering over Blue. He hesitantly put one hand on Blue’s bare femur, running his fingers slowly up the bone.

“Yes.” Blue gave him one of his bright, gorgeous smiles, and Sans’ soul felt like it might leap out of his chest. He had no idea how he’d managed to get with someone so cute, and it was a miracle they had gotten this far. Blue frowned a bit, and Sans’ soul dropped. “Are you not interested in doing this with me? I know I was excited for this, but if you don’t want to have sex, you can just tell me.”

“No, that isn’t it.” Sans turned his gaze back down to Blue’s body. Blue’s bones were fully on display, so smooth and beautiful. A few of them glowed a faint shade of blue, but Sans’ eyelights were naturally drawn to the brighter blue glow between his legs. He gulped, gently squeezing Blue’s femur. “It’s just, well… This is my first time.”

“It’s mine too!” Blue took Sans’ hands in his, pulling them up to his face. Blue pressed Sans’ hands against his cheeks, and Sans traced the edges of Blue’s smile with his thumbs. “Isn’t that nice? We get to find out what feels good together.”

“Yeah, but I don’t wanna hurt you.” Now that Sans had started looking at Blue’s face, he couldn’t turn away. The light flush on Blue’s cheeks was adorable, and the way his eyelights sparkled even now made Sans feel weak in the knees.

Sans couldn’t help being nervous, though. His dick wasn’t that long, but it was pretty thick. Even if he had stretched Blue a bit, he had heard some horror stories of what happened when you tried to push into a pussy that wasn’t wet or open enough. Besides, what if he was a one-pump chump? He wanted to give Blue a good first time, but he didn’t know if he would be able to last that long.

“Sans.” Blue squeezed Sans’ wrists, bringing his focus back. “It’s okay. I trust you. If it does hurt, I’ll tell you to stop.” Blue leaned up, pecking Sans’ teeth. “I really want to share this with you. You don’t need to be so nervous.”

“Okay.” Sans leaned in and nuzzled Blue’s face, then sat up again.

He poured some lube into his hand, and made sure he was slicked up. He lined his cock up with Blue’s pussy, then looked up. Blue was staring at him, and Sans snorted.

When Blue made a questioning noise, Sans shook his head. “Heh, sorry. This is just crazy. It’s good though.”

“Yes, it will be better when you—oooh, yes.” Blue shivered as Sans began pushing inside of him, grabbing the bedsheets. “That’s it, keep going.”

Once Sans was fully inside of him, he had to pause. Blue was so hot, and the way he squeezed Sans’ dick felt so good. Sans grabbed Blue’s hips and closed his eyes, focusing on steadying his breathing. He could do this, he just had to relax and get used to it…

Sans gasped as Blue suddenly grabbed his shoulders, pulling him down. Sans practically fell on top of Blue, barely catching himself in time. He gritted his teeth as Blue wrapped his legs around his waist too, holding him close. Shit, why was this so hard?

“Oh wow. That feels good,” Blue murmured, pressing his face into Sans’ shoulder.

“Yeah.” Sans was starting to come down from the edge, and he relaxed as Blue kissed the top of his clavicle. “You’re totally okay? No pain?”

Blue pulled back a bit, looking into Sans’ eyes. “None at all. I’m ready, you can move.”

Sans felt some of the heat from before come back, but he wasn’t close to finishing again, so he nodded. He kissed Blue’s teeth, then shifted his hips.

Sans pulled out slowly. With Blue hugging him like this, he couldn’t really look at where they were connected, so instead he stared at Blue’s face. Blue was always pretty, but Sans didn’t often get the chance to look at him from this close. He was sure that Blue would let him stare if he mentioned it, but Sans didn’t want to seem weird. He got the chance to look all he wanted now, though.

Blue’s cheeks were glowing, and Sans could see a faint blue glow of magic coming between his teeth. He was doing his best to keep his eyes open, but they still fluttered with each of Sans’ shallow thrusts. Every time Sans tried to put how beautiful Blue was into words, it seemed to fall short.

“Gorgeous,” Blue said, squeezing Sans a bit tighter.

Sans chuckled. “I should be saying that to you.”

“Well then say it.”

Sans leaned in, kissing Blue’s neck. He nuzzled into Blue as he spoke, grabbing Blue’s hips. “You’re fucking gorgeous, sweetheart.”

Blue tightened up, and Sans groaned. Blue moaned back, rocking his hips a bit. Sans quickly got the idea, and sped up his thrusts. He could feel that his pace was uneven and a bit jerky, but Blue wasn’t complaining.

There was no way Sans could last long. He’d always gotten off quickly when he was by himself, and that wasn’t half as exciting as this. He moved his thumb to Blue’s clit, hoping that he could finish him off too.

Blue started fondling his own ribs, and Sans knew he was done for. When Blue whined Sans’ name, it was too much.

Blue held Sans close as he came, forcing Sans to finish inside of him. They both moaned, and Sans hid his face in Blue’s chest as he rocked his hips. He felt Blue’s fingers rattling against his back as he trembled, but it felt nice.

After about a minute, Sans blinked, his brain coming back online. “Did you finish?”

He hissed as he pulled out of Blue, his magic dissipating quickly. That orgasm had taken more out of him than he had expected, but damn, it had been worth it.

“No, but I’m sure you don’t mind helping me with that.” Blue twisted to the side, holding on to Sans’ waist with his legs. He easily flipped Sans over on to his back, moving up so that he was sitting on Sans’ chest. A bit of Sans’ cum was dripping out of Blue, staining his femurs the colour of Sans’ magic. “Do you?”

“Uh, s-sure. C’mere.”

As Blue took his place on Sans’ face, Sans kept looking up at Blue. You only got one first time of anything, and he was determined to enjoy all of his.

Honey-Bunny

"oh, honey-bunny," Castor cooed as he nuzzled his face against her rounded, bared belly, a low purr rumbling in his chest. "yer s'cute when yer rounded with our babies.~"

"Castorrrr," Honey whined. "You can't just say things like that!"

"yes, i can. 'cause it's all true. yer the cutest when yer gonna be a momma," he replied. He lifted his head up and smiled softly at her as his lights wobbled into fuzzy hearts. "gonna be the best momma fer our babies, y'know that? gonna have the prettiest babies too; li'l buns just like ya.~"

She whined again as she wiggled on their shared, Alaskan king-sized bed, messing up her carefully made nest of blankets and heavily scented clothes in the process. "Castorrrr! They're gonna be li'l skele-buns, like both of us."

He pushed himself up further and, carefully, eased her legs apart with a soft hum. "that so, honey-bunny?" He listened as she hummed in agreement and pushed herself upright onto one of the pillows from the nest wall. "guess i gotta celebrate with a snack from m'sweet, momma bunny."

Honey giggled shyly as she spread her legs a little further for him. "Then snack away, daddy bones."

Day 5 - Size Difference

I’m working on Orgasm Denial, Monsterfucking, and the long game of the Body Swap one. Might do a few more short ones tho. 

Day Five - Size Difference - Kustard (Bara!Sans)

“Are you sure about this Red?” Sans stared down at his very nervous boyfriend. Red took a few deep breaths, backing up to look up at his task at hand.

Sans was almost twice his height, and twice his width. Sans’s hands covered half of his ribcage. Sitting in his lap, Sans could kiss the top of his head, but only if he bent his neck down. Kissing him was almost suffocating at times, and Red’s attempts at oral had always ended in something that Sans found adorable but Red found frustrating.

“Yeah, I just gotta work up to it.” Red climbed up into Sans’s lap, determined that today would be the day. He’d finally please Sans the way he pleased Red. 

“I’m flattered you wanna Red, but I told you, I’m fine just playing with you.” Sans cupped Red’s cheek (well, head), and Red leaned into it. “It’s not like I’m dating you for sex.”

“I know. But you do this for me all the time. If I can do this, then maybe…” Red blushed, shaking at the thought of what he was going to attempt. “I can please you even half as well as you please me.” Red kissed the hand, then pushed it away to take off his jacket.

“You already do darling, but if you’re sure, we’ll take it nice and slow.” Sans helped Red remove his clothes, tossing them to the side of the bed. They were at Sans’s place, and Sans was only in a T-shirt and boxers, having almost gone to bed when his boyfriend had come over. Red stripped down to just his boxers, standing up on Sans’s thighs to drop them.

“Oh, babe.” Sans stared down at the delicious display before him.

Red put his hands on Sans’s shoulders, glorious red ecto covering his torso, pelvis, and parts of his limbs. He could practically taste Red from here, staring at the wet pussy between his legs. Standing like this put him just above Sans’s face; it was fun to lean down and be kissed for a change.

Red groaned at Sans’s thick tongue working its way into his mouth. Red couldn’t really run out of air, no lungs, but this did make him feel lightheaded. Sans pulled back when the hands on his body clutched his collarbone tightly.

“You back on earth love?” Sans half lidded gaze raked over the cute red blush on Red’s face.

“Mmhmm. Where do we start?” 

“With a snack.” Red was flipped onto the bed, Sans pinning him with one hand, not that he needed to hold Red down, just hold him still.

“This is supposed to be about you!” Red tried to get up, but fell back when Sans put his thick finger directly inside him. “Saaaaaans.”

“You need some prep if I’m even gunna humor your idea.” He wiggled it around, chuckling at Red’s moans and then gasps when he licked his clit. Red bucked and whimpered, only ceasing when Sans replaced the finger with his tongue.

“You’re gunna need to f-f-f-ffffffffff-AHHHHHHH.” His tongue finally really got going, slurping up some of his favorite flavor. “FUCK! Fit three fucking fingers!”

Sans couldn’t respond, his mouth was full, but he did look up at Red’s face with glowing eyes, holding his ribs down enough to cause Red to squirm. He tapped each of his three middle fingers in turn, letting Red feel their weight and size, turning him on even more.

Sans lapped up all of Red’s juices spacing out staring out his cute, overwhelmed face.

Sans honestly never expected to be able to have Red. He was a pretty big guy, and he knew Red was terrified of him at first. Red hadn’t lived this long trusting huge people who could crush him. And even when he had fallen for the cute face who also loved jokes and science, he wasn’t sure that Red would accept him that way. AND THEN, when he did, his main concern was that he couldn’t sexually please Sans with his own body. Sans couldn’t give a damn, he got more than enough in exchange.

There was a small part of him though that was desperately curious to see if he could though. 

He pulled his tongue out when Red laid bonelessly moaning and sensitive. The two fingers fit without much complaint.

“Saaaaans…”Red thrusted against the large fingers, groaning and trying to shove them deeper just with canting from his pelvis. “More, more of you, more!”

“If you want it that bad, we’ll step it up.” The third was a tight fit, but Red’s mind was too gone to mind. Red had taken three fingers before, he had bigger goals today.

“Oh fuck, Sans, fuck, I want it so baaad.” Red gasped and thrust recklessly against them. God, the stretching drove him wild. Red didn’t know if he could be satisfied with anything less ever again. Taking Sans could ruin him, make him unsateable for life by anyone else, but he was in too deep, too desperate to please the love of his life.

“Fuck Red, I’m gunna add a fourth. You’re doing so good babe.” Sans could feel his own erection trying to escape his boxers. Red might be able to, holy fuck. Even if he couldn’t, the idea that he might threatened to drive Sans insane.

“AAAAAAAAAAH!” Red’s body convulsed at the width it could fit, mind going blank at the resistance of his ecto to the intruding fingers. Sans only kept finger fucking him under he got a clean slide in and out without Red groaning in discomfort. He left them inside Red, waiting until Red’s brain clicked on enough to actually hear him, to speak back.

“Red, earth to Red. You’re sexy as fuck and I’d go to hell for you, over.”

“Hello earth, this is Red, over. I’m…” Red looked down to his face, meeting Sans’s eyes and taking a huge gulp of air. “...ready to come in for a landing. Over.”

“Red, are you-” Sans felt his soul flip around, suddenly lying on his back. Red whimpered at the fingers being gone, managing to get around his large boyfriend and climb on top of Sans, dropping directly over the rather large bulge in his shorts.

He grabbed at Sans’s waistband, pulling down until he finally set the bulge free.

The thick blue ectocock stood about as tall as his sternum, the huge tip widening down to a width that exceeded the four fingers he had taken earlier. He stood up, straddling Sans’s waist, adjusting just right to have the tip touch his waiting entrance.

“Safe word is Orion.” Red, nervously licking his teeth and lightly rubbing the tip against himself, locked eyes with Sans.

Sans looked incredulous, clearly trying to burn this into his memory. His cock twitched at the thought, Red forced to sway with the weight of it. He leaned onto it, just until it began to stretch him further than the fingers had.

“I...can do this…” Red dropped a little further. He was so, so full. How much had he taken?

After a quick glance down, he determined a third was in, two thirds to go. He’d need to put more weight into it to even attempt to sink down.

Sans was losing his fucking mind. Red’s face glowed as bright as their ectos, even only a third of the way down his cock. That’s as far as he got before he paused. He could see the very clear outline of dick right through Red’s body. Oh, this was so worth it, maybe Red would let him just fuck him with the tip, because this was too good to walk aw-

“holy fucking shit Red”

Red had gotten down to kneeling on Sans’s lap, two thirds now, and stuck just above the thickest part of the cock. He was as far up as kneeling could leave him.

“You’re so fucking thick Sans, I can barely take iiiiiiiiit!” Red’s mouth kept opening and closing, huffing out all the breath in his body. The line of Sans’s dick glowed fiercely in him, definitely protruding far above his pelvis and bulging his stomach heavily to fit so much inside of him. His brain fuzzed over, focused solely on the burn of the stretch and the thought of what he was fucking himself apart with. He turned to Sans, and unintentionally tightened around the huge thing inside him.

Sans always kept his composure pretty well around Red, Red the one to always blush and be embarrassed by all the antics and romance and flirting.  

His boyfriend looked half feral. Sans was staring him down like others might stare at works of art in a museum. Completely in awe, swept up in overpowering feelings, desperately in love. Red moaned.

“Sans!” Red reached for him, and Sans shakily lifted his hands to cradle Red’s face, wiping away the tears gathering in the corner of Red’s eyes. Red grabbed the hands, his own shaking so bad that Sans would worry if not for the fact that Red had declared a safe word beforehand. Red pulled them off his face, and guided them to his hips. Red sank a little further, but his body resisted even under the weight of them.

“Do it.” Red pressed down on his arms. 

“Red, you don’t have to do this.” Sans rubbed his fingers in soothing circles on Red’s waist, breathing like he ran a marathon. There weren’t many monsters even close to his size, he hadn’t got to have even this much with anyone before. Red looked stretched to the brink, his body struggling to contain him. He felt so guilty, but he didn’t deny that he wanted to grab those hips and ride out everything Red could take without physically breaking.

But maybe Red could hear thoughts, because he just glared at Sans.

“Yes I do. Do it Sans.” And Sans’s control was shot to hell, because he did.

He pushed Red down, slowly but steady, and didn’t stop until they were pressed flush together. Sans held him there, because any movement whatsoever and he’d pound the life of his poor little boyfriend.

Red’s eyelights had poofed out of his face, mouth open in a silent cry. The cock sat so high in his body, overstuffed and overstimulated. He had to breath through the feeling of containing more than his body was meant to hold. But he wanted this, he wanted Sans, he needed to do this for him. Sans’s eyelights had gone into full hearts.

“Fuck babe, I love you so damn much.” Sans released him a little, letting Red bounce only an inch, but feeling the way the thrust would shake his body. “Red, baby, please, talk to me, fuck.”

“Just, go slow.” Red shuddered when Sans thrust into him, a few inches this time. He gradually increased the length of the thrust, keeping the speed slow. 

Sans had to stare directly at Red’s face. It took every single ounce of self control he could muster to not slam into his ridiculously stretched pussy, to hear every noise he could drag out of that cute little mouth. He wasn’t sure how long he could keep this up. Hopefully as long as Red needed him to.

“Red, baby, I love you, you’re so tight, I can’t believe you took all of me, you’re incredible, I love you.” Sans’s pace increased, still gradual, but clearly gaining momentum.

Red could feel the safe word on the edge of his tongue, but swallowed the urge. His body bulged and shook under the massive cock pistoning in and out of him, pounding his abused magic, starting to actually slam into him. Sans grip on his hips turned iron as Sans essentially jacked himself off with Red’s body. Red’s hands laid limply by his sides, but he brought them up to instead rub over his stomach. He glanced down at the huge dick his body was taking for Sans, his lovely boyfriend whom his soul had already sold itself to. He pulled himself off of the edge of the safe word by focusing on what was happening.

He’d been stretched wide. He had taken Sans’s cock down to the hilt. He was going to take Sans’s load deep into his body. He was going to satisfy his boyfriend, the love of his life, in a way that no one else had managed to before. He’d said no one could do more than a very enthusiastic handjob for him. That technically made this taking Sans’s virginity. And that was more than enough for him to slip back into the mood. One hand rubbing over the rapidly appearing and disappearing bulge, another straying down to his clit and nearly screamed for touching it.

“fuck” Sans sped the fuck up, needing to get to the peak, to be there with Red. He openly stared at his gorgeous boyfriend, taking him without a single complaint, rubbing himself off on the experience of being fucked apart by his boyfriend’s huge cock. Red was getting tighter, Sans’s rhythm off beat, he called out for him.

“Come on Red, I love you, fucking, come for me!”

“SAAAAAAANS!” Red screamed so loud Sans almost flinched, but the second he felt that clench, he followed Red directly into freefall.

Red’s orgasm jumped through his body like a live wire. Every nerve lit up, burning and warming in turn, while he could feel his core getting hot and full and Red couldn’t think about anything else for minutes, mentally spaced and physically sagging against Sans, unable to do anything else but breathe raggedly and wait patiently to come down.

When he did come to, he tiredly looked down at his body.

It was glowing purple. All of Sans’s cum shone through his red ecto as purple magic. Sans hadn’t pulled out of him yet, so he looked up at him.

Sans’s eyes were closed. He looked as exhausted as Red felt.

“Sansy?...” Sans snapped to attention. He steadied him with an arm and cradled his skull with the other hand.

“Are you okay?” Red tightened experimentally around the softer cock inside him. Sans sighed happily, but searched Red’s face for any sign to pull out.

“Yeah, just sore.” He rubbed his stomach. “And very full.”

“You look good like that.” Sans rubbed a hand over his taut stomach. It felt warm and comfortable. It soothed some of the ache.

“I look pregnant.” Sans paused, choosing his words carefully.

“I...don’t retract my previous statement.” His face went bright bright red. And then he murmured softly.

“It’s possible...” Sans, in awe and so, so happy, smiled at him. 

“I love you.” He bent himself down to clank Red’s head. “You’re incredible.”

“Nah, that’s you.” Red stretched his arm up and back, looking back down at his stuffed belly. If Sans pulled out here, the bed wouldn’t be able to be slept on. It’d also probably ruin the carpet. “Though for such an incredible pair, we didn’t think too far ahead on this one. How do we not fuck up all the surrounding area when you pull out?”

Sans turned bright blue.

“Honestly, I didn’t think you’d be able to…”He hurriedly explained more. “I mean, no one’s ever even tried. It’s apparently intimidating up close.” Red chuckled at Sans looking so flustered.

“You shouldn’t have underestimated me.” Red sighed, feeling up his body and marvelling at the warmth and size again. The only reason Sans’s dick hadn’t slid out by now was solely it’s girth, Red’s body couldn’t push it out even after tightening so much. “Though it’s not like I made a plan either.”

Then Red had an idea. A fucking crazy idea, his body reminded him, but he did have one.

“Hey Sans?” Sans paused his current soft exploration of Red’s ectoflesh, still in awe, to look at his face.

“Yeah love?”

“How do you feel about a round two?” Oh, Red wanted to frame that face. Sans eyes had gone dark, and he had felt a pulse from the cock still inside him.

“Red, you really want…”Sans chuckled, low and deep, rumbling his chest and Red along with it. “You’re something else.” Red could already feel his plan working, even if his body groaned at being used so soon, so extremely.

“Listen, if we move, I’m gunna leave a gross splash zone in the bedroom. But only if we move while you’re soft.” Red wiggled his hips a little. “Think you could get it up again? Even if we can’t really move yet?”

“Could I?” Sans’s voice dropped an octave. “Babe, you’re still speared on me, filled with my magic. You’re goddamn gorgeous, and you’re asking for more?” Red felt Sans really getting into it. “You take my fucking monster cock like a champ, and you still want more of it?” He stroked all over Red’s body, growling at Red’s little whimpers of pleasure. “You’re some kinda freak, aren’t ya?”

“Only for you Sansy.” Red kept his body grounded by holding onto Sans’s ribs. He left little scratches from holding on so tight.

“Of course ya are. Now that I know you can take it, you think I’m letting you go?” Sans was already half hard again. Before, it was a pipe dream to have Red once, and now he might get to fuck him twice in the same night. “I don’t need any motivation sweetheart, just gotta wait out the clock until my body will let me.”

Red shivered at the insinuation, even though he still felt plenty warm. Sans’s dick was already starting to take up a lot of space. His walls sent out bites of pain, but they were soothed by all the lubrication still sloshing around inside him. Part of him worried that even suggesting this would set a precedent that Sans could have him however many times he wanted, the only prerequisite of there being enough time to prep for the first go. 

The other part of him hoped Sans would take that hint and run with it.

“We - mmmmphh - gotta move before you go too wild, big guy.” Red could feel that Sans fully recovered, his body still freshly aching from the wonderful scrambling of his insides 15 minutes ago. So thick, so hot. Red let his thoughts go, instead just focusing on every single feeling his body had about Sans’s intrusion.

Sans nodded, but honestly couldn’t even think of how to go about it. This was gunna be awkward, even with his size.

He put an arm under Red’s back, focusing mainly on his rib cage, and made sure to push their pelvises firmly together to keep most of the cum inside. He stood up off the bed, using both hands to make sure Red was steady first, and then slowly walking towards the door. Where to go? The only place without carpet was the kitchen/dining room and bathroom, and he didn’t know how Red would feel about either of those.

Then Sans had a crazy idea, and walked them both to the dining room.

The table was kinda low for Sans, practically just better than a coffee table; he really wanted to replace the stupid thing, but now, it would serve his purposes effectively. He moved right up to the table, grabbed Red with both hands, and then spun him around.

Red suddenly felt sturdy wood beneath his hands and knees. He whined at the sensation of being flipped. And then a large hand dropped on his back.

“You feeling okay?” Red couldn’t breathe. Sans’s cock, at this angle, already sunk lower into his ribs. He’d be knocking up against his soul at this rate. Not to mention, he was already stuffed full. Sans hadn’t pulled out and emptied Red’s body at all.

“Saaaaans.” It’s all he could say. His body and soul consumed by the intense connection, half of his body was taken up by Sans now. His wrecked moans were the only verbage he could muster right now. Sans didn’t want to accidentally hurt him.

“Red, what’s the safeword?”

“Orion.” So he wasn’t all gone. Just very, very lost.

“Brace yourself.” 

Sans started slow, thrusts to reaquaint Red’s body with his size. He didn’t need more than a few before Red moaned back at him.

“More!” Fuck, he’d give him more. So much more. This angle, he wasn’t moving Red with his arms, he was throwing his weight into them now. Each thrust was powerful, rocking the table Red was on, and Red only got louder. His arms had given out, letting his back curve downward, and Sans hit even deeper.

“FUCK!” He’d tapped Red’s soul.

Sans almost panicked, but Red canted his hips backwards, trying to take more of the fucking thing into his abused pussy.

His love was a freak. A wild delicious little thing, who loved Sans of all people, and Sans helplessly wanted to please him.

Each thrust shook all of Red’s bones and sent shockwaves through his body. Soul sex usually didn’t work like this, but damn if Sans’s huge cock hadn’t demanded it anyway. Where was he? All he could think about was being pounded into, how full he was, the stretch, the cum still filling him to the brim, and Sans name over and over and over again.

Red’s only sounds were very loud moans (thank the stars this wasn’t an apartment), tongue lolled out, swept away by pleasure and Sans was about to follow him.

“Red, I’m so fucking close babe. Come for me and I’ll pull out.” Sans desperately needed to see and feel Red orgasm, but he didn’t want to overfill his small body and hurt him. He could cum on his back. He’d look great anyway he could have him.

“DON’T YOU FUCKING DARE!” Red barely held on past the words. He was gone. All wild moans and clenching, Sans whole body fucking shook and only lasting thorugh three hard pumps before he came.

He slow thrusted through the pleasure, wave after wave spilling out of him, into Red. Sans watched him inflate even bigger than he thought possible. Stomach and body distended so much further and Red could only whine and claw at the table, endlessly repeating Sans’s name to the stars.

He came back down first, holding his small lover in his hands. Red was still shaking, a wobbly mess that got quieter and quieter until he heard one crisp clear word.

“Orion.”

Sans pulled out of him, and he couldn’t get out of the way fast enough. Red’s body gushed blue magic, some getting on the table, but mostly on the linoleum floor. Red’s knees knocked together, gush after gush dumping out of him, and once it stopped, Sans gently tipped his boyfriend into his arms, overturning him from on his hands and knees, to let even more flow out. 

Once it stopped, he pulled Red up into his chest like a teddy bear. He still had a little trapped inside, but it only made him look a little chubby.

“I love you.” He kissed him gently. “How you feeling?” Red rattled quietly against him.

“Exhausted from all the bone-ing.” Red’s eyes were heavy, but he did smile. Sans felt his soul explode in fondness. He cuddled Red close. 

“Let’s get cleaned up and sleep then, my gushing beauty.” Sans laughed when he felt Red softly hit him with his fists. He wanted to see the cute blush, but didn’t want to get too unfocused. He grabbed his hoodie, and walked back with Red, setting him on the table (a clean part) and wrapped it around him. “Gotta clean the floor. I promise I’ll come back and get you clean. Just rest.”

Red yawned and pulled the comfy hoodie tighter around him. Sans used an entire roll of paper towels, turned on the shower to heat up, and then swiffered the floor to clean the residue. It’d need a better clean later, but he was just trying to get them both into bed.

After that, he carried Red into the bathroom. He hung his hoodie by the door, carrying Red with him. 

Red focused his sleepy mind to let the ecto body go, letting the last bit of blue magic pour down the drain and on Red’s pelvis. Sans gently cleaned every inch of him (and himself) before turning the water off and pulling out some towels. 

Sans’s towels were as tall as Red, and drying him was so cute, his little head popping out the top, very warm and happy. Sans gladly let him have his hoodie back when the towel came off and Red almost shivered to death.

“Finally.” Red curled up right into Sans when they finally ended up in the bed. “I love you Sans.” He would’ve been so cold if not for Sans and his hoodie to keep him warm. He wasn’t full of warm magic anymore. Vanishing the ecto helped with the empty feeling. “You know that, right?”

Sans settled an arm around Red, touching as much of their bodies as he could. His soul glowed softly in the night, framing Red in the light.

“I definitely do now. You’re it for me. I’m yours forever.” Sans sleepily winked at him. Red hummed pleasantly.

“You’re gunna fall for the first guy you have sex with? Guess I’m lucky it was me.” Red laughed, but Sans looked serious for a second. “I know you like me for me, Sans. It’s okay.”

“I’ve been in love with you for months now. But after tonight, after actually having you, feeling your soul and seeing how far you were willing to go for me…”Sans beamed at him. “I’m yours. You can have anything you want as long as I have you. I love ya Red, I truly do.”

“Good, I’m taking half the bed.” Red blushed. “And I love you too Sansy. Honestly.” Sans pulled him up for a kiss, and they settled in with a smile. Red grinned as he fell asleep, tired and aching, but sated in his very soul. 

Well, until next week, at the very least.

Hope I did it justice!
