He is perfect in everyone’s eyes; he helps when called upon, he encourages when many doubt, and he offers friendship for those who are lonely - Much like your case with him.
Yes, Papyrus is the picture-perfect example of innocence and chivalry. His knightly attitude is what drew you to him; he always gives you words of kindness and hope, he never seems to use or abuse you and it seems that no matter what happens you are always on his mind. After so many years within the darkness he was the sliver of light that reached out to you and offer you something that you thought you would never receive in your life time – unconditional love.
Yes, the tall lanky skeleton is a true friend in your books, always giving and rarely taking.
And it seems the skeleton thought of you the same way.
“HUMAN, YOU ARE THE BESTEST FRIEND I EVER MADE HERE ON THE SURFACE. THANK YOU.” He beams towards you.
“Well, it’s no trouble when it’s you, Paps.” You beam right back at him.
The two of you have the perfect companionship, a friendship that could withstand time and any storm -a relationship that is so pure and noble…. At least on the outside, to others - it would seem that way.
But, they don’t know the truth, they do not see past that gentleman façade.
The Papyrus that only he lets you see.

“HU-Human”

It’s so cramp in here, you could feel the warmth of his magic coursing through his bones - they rattle so softly as you let your fingers trail so tenderly down his exposed sternum. Clothing, both yours and his, long cast away upon the floor of the packed space you two occupy.  His heat is something you quickly gotten used to, it’s so odd but stimulating to find out that his attraction to you would trigger such strong reaction to his extraordinary body.
Fascinating, monsters are just so interesting – he is interesting. You lightly lick your lips as you finger the spaces between his ribs; rubbing slow, sometimes not. Your eyes focus on his face, your tempting but experimental touches are slowly unraveling the tall skeleton. You could hear his bones rattle more as his breath hitching every now and then.

“I-I need…” His voice is low, which is so uncharacteristic of him, it made you shiver as your own urges began to stir and awaken. You don’t think Papyrus knows how pleasurable his voice sounds – hushed and thick, dripping with wanton lust.
His boney finger tips trail their way up the side of your thighs – you lightly gasp from there feathery sensation. Papyrus let out an inaudible whine like groan as he grips your hips and pulls you close - so possessive.
The smell of his heat is starting to affect you, his sweet musk sends a pleasant haze over your mind, melting away all inhibition. You feel as if you are getting both drunk and high off his palpable lust - it’s fucking intoxicating.

“Please.”

His begging wins you over, stepping back - in what little space you have, you turn and present yourself to him. Flush within your cheeks you look over your shoulder and look up at him, nodding. This is okay; you want this, you need this, you want domination, you need his domination.
The look of a child receiving Gyftmas early, gleams within his sockets, he knells down out of your eye sight. Your heart pounds within your chest, without him in your sight your mind races with all the sinful possibilities, you can only go off the massaging and squeezing of your plump posterior.
The spreading of your lush cheeks causes you to gasp softly. His tongue, so long and thick, slither its way around your entrance – teasing and tasting your erotic opening. Papyrus is enamored by your dulcet tones, how you moan in a breathy manner - trying your best to keep quite.
More, he wants to unravel you more.
A sharp gasp escape from you as his hot drooling appendage squirm its way into your sopping entrance. Your nails softly rake against the wall as you bit into your lip, a long low groan left your throat - so debauched and full of need.
“Mmmm” purrs the skeleton as he relishes the taste of your arousal, your hips can do nothing but jerk and shudder to the movement of his ecto tongue.

Your lust is growing with every lap and slurp against your inner walls. Your body shake and quake under such attention,
“Pappy, please” you beg with a soft voice, barely a whisper.
Stars above, how could he resist that voice of yours. Withdrawing his tongue, he stood - all while savoring your flavor upon his slick conjure appendage. The only warning you were given is him taking hold of your hips. With a quick snap of his hips his long hot member penetrates you so deeply.
You inhale sharply only to claps a hand over your mouth to muffle the lewd moan that followed, his thrusting is merciless as he plunge back into your heat over and over again, the sound of bones meeting flesh cause the waves of pleasure to be amplify within your body.

“Mm, f-fuck” you huff as your drop the sleeve from your mouth.
A sharp slap to your backside makes you whimper at contact,
“Lan-language” he chides, with a slap to your back side in mid thrusts.
His pacing was fast and hard, randomly doing deep long thrusts. Your body at the mercy of his carnal act – he’s fucking you quite thoroughly. Your eyes roll and flutter as you try your best to hold back your moans, the hallway closet always did have such thin walls.
“So…t-tight.” He huskily groans as he grips a fist of your hair.
Your tongue lull out in pure ecstasy as he pull your hair, the tension on your scalp gives you a nice cocktail of pain and pleasure that you are happily and quite greedily enjoying.
Frantic becomes his pace as his climax draws near, he was becoming desperate as his breathing labor above you. The feeling of being pushed against the wall as he deepen his thrust cause you to nearly cry out his name - you bite your lip against it to stifle yourself.
Your blushing cheeks pressed against the wall as the skeleton pound into at mind numbing speeds, hunch over your quivering form as sweat drips from his brow and onto your arch back.

So hot!

Too good!

You could feel the familiar coiling of climax within the pit of your belly. Papyrus didn’t let up on his jackhammering speed, even when your walls slowly clamp onto his cock – his half-mast sockets watch the nearly hypnotic way your flesh jiggle as he smash his hips into yours.

You are the first to cum, having to quickly place a hand over your mouth as you cry out and convulse on the tip of your toes. The squeezing twitching heat of your climax was enough to send him over. The sensation of his teeth sinking into the flesh of you shoulder causes you to roll your eyes as your nails dug into the wall, he’s just too good at claiming what’s his.
The skeleton silence his climaxing groan within your assaulted shoulder. His cock throbs hot strings of seed deep into you, causing you to purr and shiver out of satisfaction.

He slowly loosens his jaw as you both came down your sexual high. Papyrus remove his teeth from your shoulder - you knew there will be a mark there again, you love it.
His and your is all that could be hear within the darkness of the closet. You feel him rest his skull upon the top of your head as you rest your body against the wall, it was cool compare to your burning body.
The sensation of him wrapping his arms around you causes your heart to flutter – such an alien feeling to you.
Ah, what a gentleman.
Slowly he pulled himself out of you, leaving behind your entrance dripping with his cum and aching for more.
Ah, what a beast.
He embraces you and hold you for what seems like the longest time, his hand was right over your heart - he feels every frantic beat, he wonders if it’s from the sex or maybe the position you two are currently in.

“I…love you, human.”
You let your body relax into him.
“I love you too, Papyrus.”
Such a cruel gentleman, but only you knew this.
