This wasn't fair.

Being sandwiched between two skeleton men on a 2-seater couch, watching the Mettaton biography special, when all you wanted was for them to head up to bed so that you could flick your bean already.

You'd been crashing at the skelebros place for a little over two weeks now, and not to brag or anything, but you'd become rather close. Sans especially seemed to appreciate your company, and you hung out together most nights, just chatting and eating at Grillby's. He was just so fun to be around! You'd pretend to groan in exasperation at his shitty skelepuns, but it was a little game you played wherein you both knew you loved them. His jokes reminded you heavily of 'Dad-jokes', something you would never tell him or admit that you enjoyed.

Papyrus really loved it when you joined him on his daily guard rounds, testing his human-traps. They never worked of course, but once or twice you had pretended to be incapacitated just to please him. The very first time, Sans had been watching, and you could see out of the corner of your eye the way his chest had swelled with pride. Whether it was for you or his brother, it really didn't matter, you were only too happy to earn your keep. The way Papyrus' eyes had lit up was for lack of a better word, utterly adorable.

"Nothing less from the Great Papyrus!" he had exclaimed, as you writhed uselessly under a net, putting on a show for him. The net was thin and not even secured down, it would have been all too easy to wriggle free, but his reaction was worth more than your human pride. He had an innocence about him that was very appealing, and with a slightly guilty heart, you had found yourself wondering once or twice what it would be like to…test it.

Which was ridiculous. What exactly was wrong with you! You were living with actual, real monsters…what state of mind must you be in to actually think about things like that?

The logic wasn't sound, but it hadn't stopped you thinking about it at night while you laid on their couch. It smelled of both of them, it wasn't your fault that it got to you. You were unsure whether these feelings you harboured were just morbid curiosity or the novelty of something different, but all you knew was that thinking about exploring their bodies was really doing it for you lately.

Which made it all the more awkward when both of their thighbones were pressed against your legs as you watched TV together. You were learning more about their physiology by the day, but the warmth seeping from their bones was a definite surprise. It was very pleasant; you had been expecting they'd be cold to the touch.

Sans shifted a little, spreading his legs wider as he leaned against the arm of the couch, his bony hand resting on his cheek as he watched Mettaton give a stirring speech on his days hosting a cooking show. Sans' leg was pressed harder against yours than before, and you felt an embarrassingly sudden twinge in your nether reigons. Since you'd been down here for so long, your hunger for contact from another person had become insatiable, and it was stupid how something so casual could set your blood on fire like this.

You must have inhaled a bit too sharply, because you could sense his eyes on you. His eyes were like that though; the soft glow from the pinpricks of light in his eye sockets made it impossible for him to be sneaky about staring at you in such dim light. You squirmed under his gaze, trying your best to avoid looking directly at him, but the intensity of it was getting to you. What on earth was he looking at, that damn skeleton!?

Finally, he seemed to come to some sort of conclusion, because he turned his head slowly back towards the TV. You let out a breath you didn't realise you had been holding in and sunk further into the cushions of the couch as your body finally relaxed.

There was a shuffling sound to your left as Papyrus dug out a blanket from between the cushions of the couch.
"Are you cold, human?" He asked, offering it to you. It was a navy blue mink blanket, with cute little duck designs all over it. You pursed your lips at it in a smirk, before looking up at him.

"Is this yours…? You asked, incredulously.

"Why, of course!" He said, proudly. "I have owned this for many years; I bought it with my very first payment from my very first job!"

Sans turned to watch the exchange, his grin widening slightly. "No fowl, it was his first…bill."

Papyrus narrowed his eyes.

"Heh. Heh. Waddle you looking at there, bro?"

You had to suppress a giggle.

"I guess that job wasn't all it was quacked up to be."

"Enough!" Papyrus practically threw the blanket over the both of you, before shrinking into the corner of the couch with a pouty lip and crossed arms.

You were laughing now, trying to disentangle yourself from the offending blanket, but your arms were too weak from laughter to be of much use. Sans was sniggering next to you too, and his eyes glowed happily as you found each other face-to-face beneath the blanket. You froze instantly, your laughter dying on your lips as you realised how close he was. His head tilted to the size quizzically as he looked you over, and it was so dark beneath the blanket you hoped he couldn't see the blush you could feel seeping into your cheeks. There wasn't much time to ponder over it though, as he was without warning launched straight into your lap. You screeched in surprise as the both of you were swaddled up in the blanket together, a resounding 'nyeh-heh-heh' left little doubt as to who was to blame. Your stomach lurched as the sensation of being picked up off the couch hit you – Papyrus had packaged you both up into a neat little parcel and had swung you over his shoulder.

"Looks like I succeeded once again in capturing a human! Plus, a bonus annoying brother!" He hollered, jiggling his prize for emphasis. Your face went beet red as the action was forcing Sans to move flush against you. He was lying almost directly on top of you, and your legs were on either side of his waist. Your nightie was hiked up to your bellybutton from the sudden movement, and it left you feeling horribly exposed. It was an extremely compromising position.

Sans was trying his best to disentangle himself from you, but his arm was hooked behind your head and the confined space was making it impossible to move. You could feel his entire ribcage through his thin shirt grate against your breasts, and the movements were forcing his knee in between your legs too. Your breathing became instantly laboured – from the stuffiness, you told yourself.

"Dammit, Paps!" Sans groaned, using his free hand to pound on his brother's back through the blanket. But Papyrus only laughed in response, deciding to take his captors on a bit of a ride. The bundle jerked up and down steadily, which indicated that he must be running through the house. Sans scrabbled uselessly at the section of the blanket in his brother's grasp above his head, but he couldn't get a firm enough grip from the constant moving.

It was then that Sans looked down at you, intending to make a joke about the situation, but he froze when he saw the expression on your face.

You had given in. You'd never been a slave to your primal urges, but this was just too much too fast. Your face was flushed as his ribs skated over your erect nipples again and again. They almost felt like fingers flicking over the sensitive nubs, and you buried your face in your hands when you knew that the skeleton man had noticed. A rush of wetness formed in your panties, and Sans' eyes widened almost comically as he felt it seep through the fabric against his knee. Papyrus was jumping up the steps of the house, one by one, laughing maniacally at his great game, and the movement was forcing the captive skeleton's knee right into your crotch in rhythmic motions. You tried to hold back your cry, but it slipped from your lips as you felt the hard bone press against your clit. It was mortifying, but the embarrassing situation was almost…turning you on more. You really were a bit of a freak.

Your face was still buried in your hands, but you sneaked a peak through your fingers at Sans. Holy shit…he was staring at you with such intensity that it knocked the breath right out of your chest. A few beads of sweat ran down the side of his skull, and his arms were shaking from the effort of trying to keep himself propped up above you. The skeletal features were scrunched up in a mixture of confusion and…oh my god, that was definitely arousal. You had no idea how his kind breathed, but that didn't matter when he was breathing so desperately through his nose, trying to keep any sounds from escaping his clenched teeth. His knee made an experimental movement, forcing itself deeper into your folds, and you felt your back arch involuntarily as you threw your head back. Sans huffed out a moan as his brow furrowed in uncertainty, but he repeated the motion several more times until your toes curled. His trapped arm gripped the back of your hair, pulling at the strands as he leaned over you even more, forcing you to look at him. As you stared up at his face, his eyes lidded and his left eye socket appeared to glow a soft blue. You licked your lips hungrily, and his pupil followed the movement of your tongue with rapt attention. Deciding to play with him a little, you did it again, this time biting your lower lip in anticipation, your eyes daring him to ravage you. His teeth parted in surprise, and you felt the fingers in your hair tighten their grip, pulling your head back and exposing your throat to him. A strange glow filled your little bundle, and it took you a second to realise that it was emanating from Sans' mouth.

"How in the hell…?" You muttered, moreso to yourself than to the skeleton still rutting his knee into your womanhood.

A tongue?

Sans chuckled lowly, his voice dark and impossibly deep. "Language…" The sound rumbled through your body, making warmth pool in the pit of your stomach and more wetness rush to your nethers. The bastard had somehow used his magic to materialise a glowing, blue appendage between his open jaws, which gaped obscenely. He slowly and deliberately repeated the motion you had teased him with earlier, and the animalistic look in his eyes made you quake to the core as the light illuminated his features. The tongue was dripping wet and intimidating long, it almost resembled a tentacle, and the skeleton man demonstrated its flexibility by leaning in and making a long, wet stripe of blue from the base of your neck to your ear. With his mouth this close, you could hear little groans and whispers of profanities emanating from him, which only served to make you want him more. You wanted that filthy mouth on you right the fuck now, and you didn't care that his brother was literally carrying your sinning ass through their house in his back.

As if on cue, the bundle which you had so wonderfully been canoodling in was dropped onto what felt like a springy mattress. Mercifully, the blanket didn't expose you to Papyrus, but the force of the drop made you and Sans roll over to switch positions. You glanced down at him in surprise as the blanket shifted a little, making only your head pop up from under it. Papyrus was standing over you, hands on hips and grinning in victory. He had somehow carried you both into his room and plonked you into his racecar bed. You panicked for a second, thinking maybe he could see what you and Sans had been up to, but Sans was now fully encased in the blanket and hidden from view.

"Remember this day human! For this is the day where I, the ever-so-great Papyrus, bested you." The taller skeleton bragged. He puffed out his chest with pride.

You felt Sans move under you but ignored him for now, you were still panting from your wild 'ride' and your mind was racing. You decided to try and get Papyrus to leave so that you could disentangle yourself from this mess, when you felt a pair of smooth, bony fingers slip into you.

And by 'into you', well, it was definitely IN you.

All you could do was stare at Papyrus, who was still laughing and preening over his victory, as his brother finger-fucked you beneath the blanket.

And you had thought you were a freak? HA.

Your thighs tightened around the little bony bastard in a warning, but it only made him do it slower, more purposefully, and he began using his thumb to circle the sensitive nub between your folds. Shit, he was good at this. How was he so good? A shudder travelled through your body, but you managed to make it somehow look like a fake cower of fear for Papyrus, who would not fucking leave and was still hanging around to gloat.

"See how you tremble before me! I must remember this trick, what do you think Sans?"

Sans didn't stop his ministrations for even a moment, but he comically lifted his free hand from the folds of the blanket to give a silent thumbs-up.

"Ah, yeah…" The sounds were out of you before you could suppress them. "Mm that really would work…"

Papyrus nodded, mistaking your face of pleasure for affirmation of his greatness. Sans twisted his fingers in a way that made your arms shake; it was getting hard to support your weight. If he didn't stop soon, you were going to be found out!

Your hands rummaged through the blanket, finding his narrow throat where they squeezed tight in a last desperate move to get him to stop. It did make his hands still…but oh no.

Oh GOD.

You felt a definite swell of movement and heat against your backside, and you realised too late that Sans was fucking rock solid.

FREAK.

You were turned on beyond all belief now, but Sans actions has also awoken a cruel streak in you. It was time for him to get what was coming to him. You skilfully manoeuvred yourself so that the blanket 'accidentally' shifted to expose Sans' face, which was flushed an amazing shade of blue. His eye sockets widened in fear as he realised that Papyrus was looking quizzically at him.

"Sans?" He questioned, as you grinned maliciously. "Are you alright? I was not not too rough with you was I?"

The question was innocent and genuine, but the way he had worded it…you felt what could only be Sans' cock pulse against you and you stared down at Sans in surprise. Papyrus moved forward and placed a gloved hand against his brother's forehead, checking his temperature. Oh, this was too good. You stealthily moved your hand behind yourself, grasping at Sans' manhood and beginning to pump furiously and without mercy. It was all he could do to not cry out there and then, but he managed to squeeze his eyes shut and shake his head as a no to Papyrus' question.

"Are you sure?" Papyrus ventured, unconvinced. His concern for his brother was touching, and it only made you grin more when you felt Sans' fingers resume their previous rhythm inside you. You had no idea he was such a kinky bastard, but to be honest, you had never felt so hot in all of your life. The thrill of doing something so lewd right in front of someone was so deliciously dangerous, and it made your head spin as you tried to hold your breath to ride out the waves of orgasm that overtook you.

Papyrus sat on the edge of the bed, still unawares of the 18+ action happening directly to the left of him, and leaned over his brother, resting his forehead against his. Sans gasped at the prolonged contact as you continued to pump him even faster, twisting your wrist on the upstroke as your juices flooded over his pelvis. His tongue lolled out of the side of his mouth obscenely as he began to pant, his breath ghosting over Papyrus' face who looked into his eyes with more concern than before.

"Your temperature is just so high, Sans! And you're hyperventilating."

"Ahh…yeah I am…S-sorry bro I just…nnngh…" Sans panted out. "It hurts a little…" Sweat poured from his skull from the effort of keeping quiet, and his tongue began dripping liberally. He wound his free arm desperately around his brother's shoulder, holding on for dear life as you felt him spurt something impossibly hot all the way up the small of your back. Papyrus' forehead was still pressed against his brother's, and his eyes widened in concern as he returned the embrace with his lanky arms, thinking Sans was just experiencing a bout of pain. He wanted to be there for him, to help him through it. The scene was both so touching and so erotic that you couldn't even stand it. Sans' bones clanked and shook as he came down from what must have been a very intense orgasm, and you felt the cock dissipate in your hands. You hadn't even realised that it had been made out of magic, it must have been the same as his tongue.

He panted languidly against Papyrus' ear, still clutching him urgently, and you locked eyes with him over his brother's shoulder. He looked absolutely wrecked, and as your mind cleared you were concerned for a moment that the whole thing had been a bit too much - that you had gone too far.

But he grinned sheepishly at you, pulling his fingers from your body and snaking his tongue out to taste the wetness on his fingers. Some of your goo dripped along his tongue and onto Papyrus' back, and it made you swallow thickly. Papyrus patted him on the back reassuringly, while all you could do was sit on top of his brother, feeling the heat rise up to your face as Sans winked at you, a promise of payback written all over his skelefucker face.
