Yandere Au Sanses [Discontinued] by Nightime_Ash

I wanted to make a yandere book, so here it is!!! You can ask for oneshots, friendship oneshots, but there will be no bad words, no inappropriate stuff, and no gore. I'll make a different yandere book that does have gore, but not the other things. This book is for the Yandere Alphabet mainly.

Psychopath Nightmare and Killer stalking and taking advantage of Ink and Dream. ⚠️ Major gore warning, I am going all out with this >:)

The title also these are my lower quality writing I may be updating some of them to fix grammatical mistakes and change them to my current writing style.

Inktober but it's written stuffs by NoneSoupForYou

It's a little thing of written stuff about Undertale and it's aus. Some for a day might be short and others might be longer. It'll have angst and fluff or just complete chaos. It'll also switch from human to skeleton, just a heads up there. Also the prompts are made up by me so..yeah. Anyway, hope y'all enjoy this!

The Enemies Maid (Ink x The Bad Guys) by frost_flames

Blue and Dream are away, and Ink gets captured by the Bad Sanses! He thinks that this is the end for him, until they tell him that he was going to be their... maid? As Blue and Dream try find a way to save their friend, Ink gets closer to the Bad Guys. Then it all goes downhill from there... The ships in this story are as follows: Ink x The Bad Guys Blue x Dream Classic x Red

Sans Aus in a school what could go wrong? Lots of things, do people die? I don't know, but ships are included. You could say it is a slow burn kinda thing or it went pretty quick, but chaos ensues and it isn't my fault. (FandomError)
