Chapter 1 The Meeting

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.
