Hi! This is my collection of undertale x reader one shots. You can request stuff any time!

After the barriar broke, Y/n, a 18 year old boy noticed many mosters move in to houses near by, and a family of monsters and a human as your neighbors. I don't own any of the art shown here, credit goes to the one who made them. Undertale was created by Toby Fox

Everyone was hanging out since the treaty was signed between the bad and the good sans. It was a party for everyone to relax and blow off steam and to try to get along.... Too along for some cases... especially Error and Lust... Or voilet/Unlust some may call him... depending on his mood of course... Things just went after that... (This is an Au btw... Should be known by errorxlust and other ships.... Nightmare and Dream belong to Joku {dreamtale} - have to put this since Joku asked everyone)

(No one did it, so I am, also cover not mine, it didnt fit sadly) After a long day at school, you decied to explore the cave up Mt Ebott, when you fell you find yourself in a multicolored world, after you find Fresh!Ink you see another version of him and now the story begins here... (Oml this desc...) (Book completed) (Old book ;-;)

Uh.... Author-chan here ♡ You're gonna read my Undertale One-Shots! Filled with lemons, fluff, um.....angst...? Is that a thing? I don't actually know all the genres... Anyways, I don't actually own Undertale but I damn do wish I did. It belongs to Toby Fox. So Reader-chan, this is you cue to go read the book and put yourself in various situations with your favorite Undertale characters! It's probably going to mostly be with Sans here, anyways. Enjoy! and vote! and comment! and send me as many requests as you'd like! (But not too many, I have a life, y'know.) ♡

Here you can read pure yanderes and I hope you'll enjoy.

You used to have peaceful Dreams but now you have aggressive and torture filled Nightmares that sometimes keeps you in them for hours at a time or they just come in the form of hallucinations keeping you awake for hours.right now your being tortured by someone who's covered in black and yellow goop.

While nightmare was giving people nightmares he got to your dream and when he gave you your nightmare he saw that you befriended the monsters that he sent in and then he got curious.
