"you are mine now (y/n)~"

 " sans ... what have you done!? why did you kill them!?" your tear fall down on your soft cheeks looking at your once dear skeleton friend is now covered in monster dust " i did what i had to obviously there were to close to taking what is mine...." sans answered,moving towards

You backed away quickly.

" what did they nearly take to make you kill them ....!?" you yelled , your eye closing slity as you glared at sans waited for his response.

Sans look at you if this was joke with a crazy slime . Make you jump a little

" it is you ....(y/n)...." sans laughed making you fear him more than you were once before.

"You love me...right !? "

You look down and stood there in silence look back at sans see that is eye sockets disappeared, leaving only blacks holes in his skull.

Taking deep breath "sans.... I am not yours ...you freak!.. you killed so many ..innocent monster !!" you hissed,quickly turning around and running away from sans like your life depends on it.

Sans took this badly just stared off at you as you ran make sans

Laughed to himself.closing his eye sockets

His hand starts to glow neon blue snapping his boney fingers disappearing and reappearing in front of you make you crash into him.

Feeling his arm around you hugging you tight pressing your chest to his bone chest

Putting your two hands against his chest trying to get away from him seems that sans hug you more tight not letting you go.feeling sans cold breath on your head make you shiver " you now......." sans move one arm rubbing your back up and down slowing and the other arm hold you and places.

" you so cute .....in i going to keep you to myself "

Make you cry wishing this is just a dream.

Feeling his bone fingers wiped away your tears replaces your face with some

Of monster dust.

"Shhh.. don't cry ..(Y/n).." with a clam voice make you feel safe and warm but you knew very well that sans killed all of them toriel,undyne,aphlys and ... papyryus more tear falling down your face

Realizing that there NEVER coming back.

" sans ......w-why me ..." you said

He smiled and kiss your soft lip he move to look at your drown eye

" Everything .....(y/n)..can't you see?" he responded

" G-Get away from me!" you screamed throw punch at his bone chest

He grabbed your hand stopping you from punch him in the chest

" i don't think want to (y/n)...."

You opened your mouth to protest, anger boiling inside of you. Only to silenced hiss teeth onto your lip, and almost instantly you tried to pull away, you were held in place by a pair boney of arms wrapping around your waist, squeezing you tightly against his bone chest , making you  wince .Sans noticed you're doing and pinched your hip cause you to yelp,Sans took the opportunity to slid his tongue inside your mouth explore everything and inside your mouth, you instantly pressed your hands against his ribs attempting sans off you a low growl sounded from him making you stop fear that sans will kill you,You got an idea, you bit his tongue hard, Feral growl escaped sans mouth as he pulled away , his neon blue tongue dripped out his mouth as he glared at you, A dark aura spread around on sans

" D O N'T even think about it ... you are mine now (y/n)" he growled into your ear, making you tense.

" you will love me as much as i love you ...understand (y/n)" as you nodded your head, knew very well that you have no choice to say yes

Your eye filling with tears of regret wishing that you didn't fall in that underground world. And perhaps my friends would have never gotten hurt.

Feeling sans wraps his arms around you body, rests his skull on your shoulder and hummed a song

" Now .. you mine and only mine (y/n)..."
