you fall in the underground and a little skeleton falls in love with you and kills for you what will you do? what will happen? well you got to read to find out!

You where dating Sans until you found him cheating on you with another women. So you make a decision to leave him and move on. Sans also makes a decision. A decision that you wont be leaving him. EVER.

This is a yandere sans x reader. there will be some lemon. I mean, honestly! There are tons of these', and none of them are actual smut. Ok, time for background info. You are a human that fell into the Underground. You have lived with goat mom for 5 years, making you 15 years old. You asked Toriel if you could leave, and she allowed. now you meet Sans, and that is where this story begins. I don't own characters. this is set in classic undertale. Smut, gore. got it? good. Might be slow updates.

hey guys this is my first yandere story and i hope you like it and it might be short but its something right? hehe ok onwards to the story. and i will maybe update with more stories of yanderes just leave a comment below and ai will try to make that yandere ok.

I'm just adding on to someone els because they are to lazy to make a ending. So I'll just finish it because I'm pretty board.

This is my first story but i have been told i am a good writer soooo enjoy i guess.

The funny skeleton we love and we thought we knew takes a dark turn. Any images used belong to their rightful owner.
