Chapter Text
Too ashamed to open your eyes and blushing desperately, you curled yourself closer into Sans’ broad ribcage as he effortlessly carried your trembling body across the room. Reaching what appeared to be a lab table, Sans dumped you unceremoniously onto its cold metal surface. Sans smirked as he gently ran his claws up and down your stomach, with just barely enough pressure for your skin to tighten with goosebumps at the teasing touches.
“Can you be a good girl for me?” he murmured, caressing the soft flesh of your tummy. You let out a low moan and arched into his hand, desperate for more of the pleasant contact. Sans chuckled devilishly at your reaction and increased the pressure, his fingers digging into your skin.
“Answer me,” he growled. “And make sure to do it properly.”
“Yes… Master...” you choked out in a whispering whine, biting your swollen lower lip.
He chuckled again, his low pleased hum reverberating through your spine. “That’s it… Such a cute, obedient little human… And you’re all mine.”
Sans trailed a single finger up your torso, getting agonizingly slow as he made his way up to the bottom of your breasts. As he traced carefully over the soft swell, he pulled his finger away just as it barely grazed the tip of your nipple. You moaned loudly at the jolt of electricity that coursed through, then began to whimper at the loss of contact. You felt your nipples get almost painfully erect as you arched your spine off the table.
“Heh, are all humans this desperate?” Sans let out a husky laugh. “Just look at your face… You’re practically drooling for me.”
He circled each side with a tantalizing finger, spiraling closer and closer until he finally reached the rosy peaks and toyed with them roughly. You panted and wailed wantonly as he squeezed the tender flesh of your breasts, pushing them together and flicking his thumbs unrelentingly over your hard nipples.
“Ohhh, you like that, don’t you?” he growled, baring his fangs. “I think I’ll have a taste…”
Opening his jaw wide, Sans let his gooey red tongue curl down his chin. He pulled hard on your arm, jerking you into a sitting position. He immediately buried his face into your breasts, lapping at the sensitive skin with his hot, slimy tongue and rubbing his hard cheekbones all over them.
“Ughhh, so soft…” Sans groaned. “Why does your body have to feel so fucking good…”
He bit down hard on one nipple, licking and sucking at it through his teeth. With one hand he mercilessly tweaked the other, twisting and flicking the quivering nub until you thought you’d go insane from how painfully good it felt. You bit down hard on your lower lip as you were flooded with wave after wave of pleasurable shocks that coursed swiftly down to your core, inner thighs already slick with your fluids. Instinctively, you wrapped your legs around Sans’ torso as he worshipped your tits, holding on tightly to his clavicles to ground yourself.
“Fucking… shit fuck…!” Sans swore, stumbling a bit as you groped his bones, and you felt his entire body rattle. His face was flushed red and saliva dripped down his chin. In a flash, you were thrown back onto the lab table, your hands locked firmly above your head with hastily conjured magic chains.
“Can’t keep your hands offa me, huh, kiddo?” He smirked breathlessly. “Sorry to break it to you, but I’m the one running this show.”
Continuing to toy with your sensitive breasts with one hand, he leaned forward and kissed you deeply, shoving his tongue inside and swirling the tentacle-like appendage lewdly. His other hand groped slowly down the side of your body until it was squeezing your ass.
“You know, someday I’d like to spank this part of you till it’s bright red and quivering under my palm…” Trailing his tongue up your neck and in your ear, he growled. “Then I’ll bury myself in your ass and fuck you into the ground.”
You mewled weakly, and he chuckled, grinding his teeth into the crook of your neck. “Mmmm, but let’s save that for another playtime. Right now I want to claim this tight little pussy of yours… I remember how tight you squeezed around my fingers before, I can’t wait to feel you around my cock…”
He pulled away briefly, then slithered his hot tongue one last time over each of your oversensitive nipples. When he abandoned your chest to trail licks and nips down your torso, the cold air in the room ghosted over the stiff wet peaks and made you shudder violently. You writhed under him and the chains jingled weakly.
When Sans finally reached the apex of your thighs, he paused, sweat beading on his skull.
“Fuck…” he exhaled hotly. “You’re so fucking wet.”
Instinctively you pressed your thighs together to hide yourself, and Sans made a sound of disapproval.
“Now, we can’t have that, can we?” Sans murmured. He flicked the air and more red chains appeared, twining around your ankles and dragging slowly until your legs were splayed out and suspended in the air. He ran his tongue over his sharp canines before settling in for his meal. He ran the broad flat of his tongue up in one long stroke from the bottom of your folds up to your sensitive clit. A frantic moan caught in your throat as you thrust your hips up to meet him.
“Ooooh, eager, are we?” Sans snickered. “I suppose I can spoil you a little bit…”
He swirled his hot tongue around your clit then started to dip teasingly in and out of your quivering entrance. When you hiccuped and mewled haltingly you felt him grin against you and start slurping at your folds with renewed vigor. His hands crawled up the backs of your thighs until they were gripping your ass.
“Such a cute little pet… Trying to hide how good it feels....” he mumbled against you. “But I can see it written all over your body.”
When Sans lightly grazed his fang against your clit, back and forth, you tensed and clung desperately to the chains wrapped around your arm as you felt your body winding up towards sweet release.
Sans chose that moment to pull away, making you moan deeply in disappointment. He was breathing heavily, skull flushed red and his jaw slick and shiny with your arousal. He flashed you a lopsided smirk, the glowing red pinpricks of his eyes hooded with lust.
“Time for the main event,” he growled.
Sans shoved the waistband of his shorts down and his erection bounced free, trailing a bead of gooey red precum from the tip. His magic dick twitched and continued to drip ectoplasm as it stood at attention just under his ribs. To your unexperienced eyes it looked huge, with a monstrous girth that you were certain would tear you in half. Despite the fear, something clenched deliciously inside you as you imagined taking the mouthwateringly thick cock between your thighs.
“Whatsa matter?” He smirked. “Never seen a boner before?
Abruptly, the chains released you and you fell back limply, your hair falling in wild tendrils around your flushed, sweaty face. Sans loomed over you with a dangerous grin, making you feel incredibly small and insignificant. He slammed one hand down on the table near your face and leaned forward, pressing his hips insistently against yours. His hot breath prickled at your ear as he panted with need.
“That face you’re making… ” He grunted. “Just begging for a good fucking ...”
Sans ground the tip of his cock up and down against your slick folds and you whimpered. Slowly, he began to breach your entrance, the thick head of his cock stretching you painfully wide. Your walls strained around him, the burning stretch bringing hot tears to your eyes.
“I-It’s too big, please, I can’t--!” you sobbed.
Ignoring your pleas, he slammed his hips into yours, forcibly burying his cock into you as deeply as it would go. A throaty scream escaped you and your eyes rolled toward the back of your head.
“So goddamn… tight…” Sans hissed through his teeth. “It’s like you’re sucking me in…!”
Thankfully, Sans didn’t move, instead enjoying the sight of you squirming deliciously beneath him. His member twitched inside of you as he remained buried to the hilt, struggling not to give in to the urge to thrust wildly. You bit your lip so hard it bled, hardly able to breathe.
He pulled your torso up until you were straddling him and you instinctively threw your arms around his shoulders. Something tender passed through his eyes, and he pressed his skull against your forehead.
“Good girl...” he murmured.
Sans brushed your lip with his thumb and slowly began to drag his cock out of you. When his tip was grazing your entrance again, he slammed back inside you with a strangled growl. And again. And again. The pain jolted relentlessly through your core and blossomed into hot, pleasurable sparks, and each time he pulled out you arched to meet his thrusts halfway. Tears rolled endlessly down your burnt red cheeks, throat feeling raw from the succession of desperate moans and whimpers being extracted from you with every thrust.
When he reached down to rub your clit between thrusts, your entire body jerked and you cried out his name.
“Sans…!”
He froze.
“Say it again,” he commanded, his eyes dark with need. “S a y m y n a m e .”
“P-Please, Sans… Don’t stop… Sans…!”
He growled viciously and threw you back onto the table, draping one of your legs over his shoulder and rutting into you relentlessly.
“L o u d e r .”
Phantasmal red hands appeared out of thin air and began groping lewdly at your body, massaging your breasts, gripping your waist, shoving two fingers into the side of your mouth and forcing it open wider.
“Saaans!” you moaned, your cry muffled by the invading appendages.
“ F u c k . . . ! ”
Sans lurched forward and bit into your shoulder, forcing your body to bend so that your knees grazed your oversensitive nipples. He ground his teeth into your flesh, humping wildly into you with the crazed eyes of an animal in heat. The change in angle caused him to pound directly into a tender spot deep inside of you over and over, the feeling so extreme you felt yourself start to black out.
You screamed his name one last time as you reached your climax, your walls spasming erratically around his thick cock like a vice. Sans let out a choked groan and buried himself deep inside you, grinding against your cervix as he let out searing hot spurts of cum that overflowed for lack of space and dripped out of you onto the table.
He collapsed directly on top of you, panting and possessively clutching your limp form to his body. A deep growl rumbled from his chest as you drifted out of consciousness.
