I Fell for a human -_Underfell!Sans X Reader_- (lemon)

(SLOW UPDATES AND UNDER EDIT)

You are a young adult, around the age of 19.
You don't really have a gender but can be called he/she or they
You were living with an awesome family when your father turned insane and killed your mom, brother, and two sisters while they were sleeping.
You on the other hand were wide awake when it happened so you got away but your father followed you.
He followed you all the way to the famous Mount Ebott where anybody who went there never came back.
You thought you had lost him when he made you fall into the underworld
Called Underfell

Will you survive the torture of a certain short skeleton?
Or will you be killed by other monsters in your journey?

Sans does treat you like a slave when he finds you, The Genocide Route is open for taking.
Kill or be killed is what this world will make you to be
