a new life down there

this is a fell sans x reader, why you might ask? because I do not need to create a name for the character I created. XD.
it was only 7 years since he changed still, he became what he so much hated. a monster is what he became. his soul has rotten and his friendly smile has faded to a crooked one with no happiness behind it. what also changed was how he treated you. at first, you were happy with the change. but now you wanted to back to it was back then when you were both younger. he needed to get out of that house. but after you knew why he was in this state you decided to free him and yourself. you must save the monsters down there. for your sake and that of your family

I hope you like it. also, it has 18+ shit because of eeuh ye...... I had a dream about that so you have to read that dream now. '

there will be no random dick here just soul shit you know...........
