Puff.....Puff..... come on you have to keep running (Y/N), dammit you yell in your head biting your lip making it bleed.

"Come on (Y/N) i'm tired of running after you in this silly game"  sans Yells from not far Behind you in a sing song voice. Tears start running down your face.

He killed them all, you hiccup rubbing your eyes trying in vain to stop the tears running down your face.

Is it my Fault? what did i do to make him snap?

FlashBack--

Come on sans, were going to be late you yell smiling ear to ear turning around to look at sansonly to see him not there you raise an eyebrow in confusion, you yell in surprise as you feel arms wrap around you lifting you up and throwing you over there shoulder, turning your head to see sans smiling, didn't mean to scare you. You smile Hugging him back, come on Sans were going to be late and you know how papyrus is, Sans nods his head as his eyes flash a blue but you didn't see already turned around pulling him

over----

You throw yourself into a snow pile covering yourself up as you hear footsteps stop in front of you, hearing a sigh you feel yourself being pulled out of the snow pile, your tears frozen to your face you let out a cry in protest trying to get away from him.

"Calm down (Y/N), I don't understand why you're acting this way" sans yelled out in anger

Never had you seen him mad it scared you, you shut your eyes as tight as you could and curled yourself into a ball whimpering out "sorrys" and please don't" Sans let out a breath pulling you closer, starting to walk back to his and papyrus house.

time skip--

Sans set you on his bed in HIS room, never had you been in his room only outside the door waking him up or telling him the food was done, looking around his room it was messy and you could tell it was his room you smile to yourself, you feel the bed sink telling you someone sat beside you snapping you out of the good times making you from and tear up again.

(Y/N) please look at me sans pleaded with you, You bit your lip again winching as you make it bleed again. Sans sees your lip bleeding and pulls you to him his eyes tearing up "I'm sorry (Y/N), I never wanted to hurt you or the others but they were in the way and an....." He hugs you tighter to his chest laying down on his bed flip you over so he was on top of you straddling your hips "you're going to have a real good time tonight (Y/N)" Sans said into your neck in the corner of your eye you could see a bright blue light.

Your body shudders with pleasure, not in control of your body anymore, Sans lets out a laugh knowing he's getting to you , Sans starts moving his hips rubbing on your area Sans eye start glowing brighter as the time went on.

Soon after that you were panting and huffing trying to catch your breath Sans layed next to you sitting up and doing something with his hands, soon after you feel him pick you up and walking to a blue glowing door, you close your eyes as what he did to you flashes in your mind

flash---

As he thrust his hips over your area you close your eyes trying not to let out a moan, "come on (Y/N) let it go, let everything go your mine now, NOBODY CAN HELP YOU" Sans yelled out in a sadistic cry of madness, you let out a moan/cry as you know he's right. Hes movement gets harder, finally you let out a loud moan, stopping Sans from his action Sans start whispering things and snaps his fingers together as you lay under him with nothing on and his over top of you with a blue member, "Magic (Y/N) MAGIC" Sans says as he sees your eyes on him, noticing your cold you cover yourself up from him seeing your body.

Sans let out a cry of anger "Never hide yourself from me, YOU'RE MINE NOW" you let out a whimper as he put two fingers in your sex, you let out a cry and arched your back as he started moving his fingers in and out of you in a fast manner, Sans sees your mouth open and leans down and kisses you, you try to fight back, Sans adds another fingers and you gasp again and he slides his long blue tongue into your mouth roaming every inch of your mouth making you understand he owns you now, against all odds and your body betraying you, You let out another moan and feel yourself getting hot, you relax and when Sans pulls away your a flustered red mess and he's loving that he can do that to you.

He pulls his fingers out of you and puts himself as the entrance of your sex he looks at you dead in the eyes, his blue eye brighter then you could ever think it could go " this is it (Y/N) you're mine now" Sans says in a very husky tone filled with insanity and love as he pushed himself in to your sex, you let out a cry in pain and try to push him away, making him sigh out in pleasure not noticing your struggling as Sans start moving in and out slowly, Gaining speed the less you cry out in pain, soon enough Sans thrusting into you in an inhuman speed making you cry out but not in pain, you wrapped your legs around his bone body and cried out his name, as his blue flames enveloped you both " I'm cumming oh god (Y/N)!" you let out a loud moan telling him you were to, you both came with one another, Sans fell on one side of the bed as you tried to catch your breath

Flash over----

Your his Now Sans hold you closer and you let his name slips off your tongue making him shudder, Stepping through the Blue door you see a bed and what looks like a shower room, releasing what's happening you struggle to get free, how could you be so stupid Sans lets out a chuckle " welcome to your new home (Y/N)" NO!! you scream as Sans waves his hand making the door to fade along with your freedom, a tear slips out as Sans pulls you to him kissing your neck making everything turn black

I'm Sorry i Wasn't Strong enough
