Waking Up Warming Up

Dedicated to FireRose2001 for reading this and giving me motivation to post it! Thank you so much!!!

When you woke up, it was rather quite cold. A quick glance around confirmed that the wetness you felt seeping into your bones was snow. Dang it. You pulled yourself up, long black hair hiding your face. You slipped your hands into your hoodie pockets, hoping the grey fabric would keep them warm enough to not get frostbite. You walked along the path, miraculously free of snow despite how deep it was when you were lying in it. A bridge reared up from the horizon, two bars on either side of it as if stretched across a chasm you probably could have jumped across or walked around if you could have been bothered. You tilted your head. Was it supposed to be some barrier? Well it wasn't a very good one. You could easily fit through, even if you weren't so short. You went to take a step, but the snow crunching behind you made you freeze. A deep, soothing voice made you jump and nearly slap the person behind you.

"Hey now, is that any way to greet your new friend?" As much as the voice was smooth, it also sounded rough too. You doubted they were going to be your "friend".

"Turn around and shake my hand," they demanded. You turned around, slowly. It was a skeleton, taller than you. He wore a red jacket with black faux fur around the hood, black basketball shorts and red sneakers. He held out his hand and grinned, revealing a row of shark teeth, one gold, and white pin pricks for eyes in his eye sockets.

You narrowed your eyes at him, but grabbed his hand to shake anyways. But that's not what he had in mind. He pulled on your arm, the force pulling you to him and effectively making your hips meet his. You instinctively wrapped your arms around his ribs (since he wouldn't of had a stomach) instinctively.

"Hey toots, name's Sans~" he leant down and growled into your ear. You pulled a face at him, but gave him your name anyways.

"A sweet name for a beauty like you..." He grinned, and it reminded you of a predator, like you were his next meal. Or play thing. You flopped back in his arms, to look back at the bridge and effectively gave him a good shot or your boobs and pressing your hips against his.

"Oh, that?" He eyed your chest, although you weren't looking at him. "My brother hunts humans. It was meant to stop them coming through~" you shivered at his tone, pulling yourself back up to look at him face-to-skull. "I couldn't care less about capturing one~" you could tell he was lying. "But he's a fanatic."

You questioned why you weren't trying to escape Sans' intimate hold. But you just couldn't be bothered, and to be honest you were enjoying it. Even if it was for all the wrong reasons.

You looked him in the sockets. You still felt sleepy and extremely lazy. You pushed his arms away, and Sans' eye flashed a red until you jumped onto his back, wrapping your arms around his neck and resting your head against his shoulder blade, rubbing your crotch against his spine as your legs rested on his pelvis. Sans chuckled, and the vibrations ran through your body and down your spine. "Guess I'm taking you home," he chuckled again and grabbed your legs, beginning to walk through the snow until a flash of red overtook you and you were suddenly in a dark-ish room. It seemed messy from what you could tell, before you were thrown onto the un-made and surprisingly comfortable bed.

Sans stood by the door, left eye glowing a fiery red, the same glow coming from his pants. You heard the door lock as he walked over to the bed and crawled on top of you, grinning at you as he lowered himself onto you and pressing a hardness you didn't realise he had against your stomach as he held himself up with his arms. "You're a real tease toots~" he said, looking down at you with a long, red tongue lolling out of his mouth dripping spit onto your hoodie. Sans lowered himself more until his boner pressed against your clothed crotch, and began to move himself against you. His eye flashed as a moan escaped your mouth. You loved the attention, even though you didn't known Sans for more than five minutes. Fuck it, you thought, and wrapped your arms around his neck and lifting one leg to wrap around his pelvis.

"Oh fuck yeah~" Sans groaned and went harder. You pushed him off of you and sat up, taking off your hoodie, pulling it up over your head slowly, and hopefully sexily. Sans stared at your bra-clad chest, tongue lolling of his mouth again. You loved making him this way, even if you just met. You couldn't take it anymore, you wanted him to rub up against your flesh, wanted him inside you no matter how he did it. His bony hands instantly travelled to your jean zip, undoing it and slipping his hand inside your underwear, and then teasing you. You groaned, putting your hands on his shoulders and spreading your legs wider. He smirked at you, licking your cheek with his tongue before dipping a finger inside you. The intrusion made you moan, biting your lip and moving your pelvis around. Sans moved it in further and then back again. You couldn't help but bite your lip harder but moan anyways. It seemed like Sans really loved it when you did.

"M-more Sans, please!"

Another finger joined the first, and then another, until he was almost fisting you. Your walls stretched and burned, you couldn't help but feel like a masochist for enjoying this pain you had never felt before. With him inside you, the urge to have his mouth on yours was overwhelming. You grabbed his jacket and lay back, pulling him on top of you. You yanked his head down, arching your back with his fist still inside you, smashing you lips against his. He was a skeleton, but somehow he magically could kiss you back while fisting you. He was the best skeleton ever (and the only one you knew and would ever need). You moaned against his lips, arching your back and squeezing your legs against his wrist. Every time he moved his fist, a squelching noise reddened your cheeks. Natural lubricant really comes in handy, no matter how embarrassing it was. Sans pulled away, his eye sockets closed half way, left eye burning a passionate red. He groaned. "You're so wet~" you blushed and groaned in half-assed embarrassment.

"Just fuck m-me already," you panted, looking up at him with a lust filled gaze. If you were honest, you were losing your mind. Sans was in you, but you really wanted was him to fuck you, hard. A primal urge was rising up and taking over. You pushed Sans away, effectively making him pull his hand outside of you, and hooked a finger inside his basketball shorts, mouth open and eyes lidded. Sans sucked on his fingers, coated in your juices, and slipped out of his pants. You ran your hand over his exposed ribs under his jacket before you allowed yourself to look down. Sans shivered under your touch, glow brightening. He was big, from what you could tell. You licked your lips, and vaguely thought should you really be doing that? Before thinking fuck it and took him into your mouth suddenly, making Sans inhale and groan at the wetness around him. You had taken him by surprise. A bony hand that wasn't inside you grabbed the back of your head as you sucked and licked, bobbing your head hesitantly. You closed your eyes and focused on not letting your teeth touch him. Sans' grip on your hair tightened and pushed your head down as he thrusted up. You choked, but refused to pull away as he continued to fuck your mouth. You did your best, and soon you felt his cock swelling. You wanted to pull away, but his hand prevented you from doing so. He pressed his hips forward, his dick going past your cheeks as a warm liquid came into your mouth and down your throat, swallowing the rest as he remained in your mouth after he was done. Sans panted, pulling you up by the hair as his seed dripped from your lips and down your chin to your bare breasts. He kissed you roughly, sticking his tongue in your mouth to wrap around your uvula. You gagged, trying to pull away but Sans' hands were planted firmly on your hips. His tongue pulled down on it, rubbing it before swiping across the roof of your mouth. Your tongue rose to meet his, his taste still coming on strong. Surely Sans could taste himself in your mouth. He smirked against your lips, retracting his tongue and pulling away. You followed after him and opened your eyes, whining. A trail of spit linked your mouth to his. You pouted.

"My brother will be home soon~" he half purred into your ear, pulling your jeans off and hugging his bare (and now dickless) pelvis against your ass as his arms wrapped around your waist and put his face in the crook of your neck, nibbling on the skin there.

You huffed. "You're fucking me next time."
