Underfell sans x Female Reader

***LEMON***

The day you fell down into the underground was the day your life flipped upside down, not that you mind. Sure the monsters here wanted to kill you but if you show that your not some weakling they respect you, well most of them. It was kill or be killed after all.
Your not sure why but lately Sans has a bone to pick with you. He is more rude and vulgar when your around. Undyne says it's probably because he's hiding something which gets you very curious. What could Sans possibly want to hide?
You try to ask Papyrus but it seems as though he doesn't know either. The only info he did give you is that Sans spends more time in his room lately and rarely comes out. This gives you a plan of action.
You wait to see Sans leave his house with your own eyes and sneak into the house. Making it up the stairs to Sans room you find the room to be unlocked for some odd reason. With curiosity in mind you sneak into his dirty room. Nothing out of the ordinary catches your eyes and you debate on whether or not you should confront the skeleton about his behavior.
Deciding that confrontation may be the better choice to satisfy your curiousity you sit on the bed and wait.
And wait.
And wait...
And lay down...
And fall asleep.
Your awoken by the front door slamming shut. You rise to a more sitting position when you see Sans walk into his room. His eyes are automatically on you as your rub the sleep from your eyes "Its about time you got here, I fell asleep waiting for you." He didn't say anything but he approches you cautiously. Why is he being so cautious?
He takes a seat next to you and just stares, which makes you feel nervous all of a sudden. "W-what?" You look away from him as you stutter, you never stuttered in front of anyone before.
It's dark in his room but some light is being emitted from the window, giving the room a blue like glow.
Let's see, your in Sans room, your on his bed with him and he hasn't said a single word, and its dark....and your alone with Sans... These thought make more nervous as time passes.
Sans boney fingers graze your chin and slowly you turn your head to look at him, he's got this far away look in his eyes that you've never seen before. It's cute. Giving your situation and the way Sans is oddly treating you makes you blush. He takes notice and chuckles in a deep alluring voice "ya know doll face, you surprised me." You try to look away from him but the way he was rubbing your lips generally with his fingers made you shiver and unable to look away " I never thought you'd be so eager to jump my bones. I mean look at your situation here. Do you think there is any escape for you?" He smiled his sinister smile but there was a softer side to it.
You smiled and gently placed a hand on his thy making you blush more and knowing exactly where he's going with this. Sans face blushes red when you place your hand on his boney thy and slowly move it toward his pelvis. Two can play at this game. Slowly you lean and whisper to the side of his skull "who said anything about escaping?" Slowly you brush your hand against his bone and he lets out a low grunt and slowly puts his boney hands on your hips pulling you into his lap. You took this chance to look Sans in his eyes, they where full of lust and a hint of something else. Could this be why he was been avoiding you?
You wrap your arms around Sans neck and Sans blush darkens "Why where you waiting for me anyways?" He is being much kinder than usual... You look away "I was wondering why you were being more...rough around me. Is it because your hiding something from me?" He chuckles "Well.. maybe its better if I show you why." With out warning he slips his red tounge out of his mouth and slowly grazes it on your neck making you shiver and he lets out a low growl. "Mmmh, your skin is so soft..." You pull him closer to you and he takes a bite of your shoulder making you his in pain but in pleasure as well. Sans releases you from his bite and laps the mark hes made on you and moans at the tast of your blood. Slowly you move your hands under his shirt and start rubbing his sternum, he leans his head back and you make a attack for his neck and slowly lick it. "Nng, hehe Hey Im suposed to be the dominante one here..." You nibble his neck and he makes a loud moan which makes makes you smile "Nng!" Sans quickly recovers and flips you onto your back and hovers over you with a toothy grin "Your blood tasted so good, I wonder if the rest of your body tastes just as good..." You blush as Sans hand slides under your shirt and tears it off "Hey! I liked that shirt!" He grins "And I like it off." To make a point he starts to rip the straps off your bra untill they are finally off and exposing your (size) breasts making you blush. He chuckles darkly has he grazes your skin with his tounge and masases one of your breasts making you moan. "You like that doll?" His tounge flicks your nipple making you moan slightly louder, you can feel your body ake in need. "Sans..." He stops and looks at you in your (e/c) eyes with his red ones that are full with lust "Ya doll face?" You can feel your body growing hot and you advert your eyes away from his and whisper "please...." Sans chuckles low and suductive as he keeps his gaze on you "please what? Look at me when you say it." Your face grew red but your body grew hotter as you turned your eyes back toward the skeleton, you wanted it, you wanted all of it and my god you where enjoying it. If this was a dream please, let it never end. "I..." Sans hands began to slowly move down your stomach making your lower areas grow hot with need for attention. "Please Sans..." His hand stops when it reaches the button of your pants and he raises an eyebone "Please what? You got to be more specific." This is torchure, pure torchure, you want to tell him but are so nervous too, your about to get boned by this suductive and attractive skeleton and he wants you to say it out loud for him, of course your nervous but, maybe he thinks you wont be able to say it? If thats the case then he is so wrong.
You look Sans straight in the eyes and beg "Sans please...please fuck me!" Sans skull shades a dark red and his grin twitches and this time he looks away from you for a second and chuckles nervously "Hehehe, I didn't think you'd actually come out and say it....and like that..." He removes your pants with ease along with your underwear. You now lie completely exposed to him. "Well look at what we got here..." He lightly places two fingers between your legs "Seems like my little girl here is all worked up."
His little girl? The thought makes you blush that he conciders you his...technicly your about to be.
"How much do you want me?" Sans removes his shorts and exposes his red cock as he strokes it in front of you. You wimper a reply "B-badly." Sans smirks and positions his shaft at your enterance "Are you ready to" Oh no "to enter the" please don't tell me he's "Bone zone?" With that he slams into you making you scream in pleasure and pain. You grab his shoulders as he pumps you full with his length and moans loudly "Damn...uh...you feel so fucking....mmmmng good!" You moan loudly and Sans takes this as a chance to make out with you while pumping you full. The feeling of pleasure overwhelms you and you can't help but be a moaning mess, then you feel something rubbing against your clit making you moan louder, Sans breaks the kiss and you see many red tenticles around you rubbing you in many places. "Sans...Sans...Sans.." The only thing you can manage to say is Sans's name. "Yes...say my name louder." You comply "Sans" The pleasure is too much "Louder" You don't know if you can take much more "Sans!" Any minitue and you'll "LOUDER!" Your about to "SANS!!!"
Both you and Sans reach your climax and colapse on the bed in a sweaty, panting mess.
Sans rolls off of you and stares at you with a grin "I love ya doll face."
Your face grows red as you smile back at him "I love ya too."
He chuckles "We are definitly doing that again."
You laugh "Yes, definitly."
