A Book Of UnderTale Oneshots But It's mostly Sans suffering
~Discontinued until further notice (Sorry :< )~ angst, fluff, ships, xreaders, (but mostly angst because haha Sans suffering go brrr) I'll do it all! Except Fontcest, I don't really ship that. And Lemons, limes, or smut. Sorry, I'm not a sinner :/ But this book is basically me just putting down random oneshots that come to mind! Lot's are inspired, others are my ideas! Anything inspired I will put credit to the person I was inspired by! There will also be oneshots that I've already written thrown on here! (Avalanche, Stop or suffer, etc.) If anyone actually reads this and has a request, just comment it below. Alrighty, let's start! (btw none of the art in the stories are by me, unless I say so.)

YAOI, SLASH AND ALL THAT. If you don't like that, don't read! Adding warnings as I go... Warnings will be in chapters. Please tell me if I didn't add a warning where there should be one and I'll add it.

A bouquet of oneshots, by me, for the lovely reader who took their time to read this! Requests are gladly accepted, but be warned, I procrastinate a lot and I'm a very busy person, so they will take a long while. Slow updates! Like very slow

Sanscest One-Shots (old)
This is a bunch of Undertale one-shots. And a bunch of Undertale and Undertale AU ships. Most of these ideas I wanted for books but, don't have enough time nor ideas. The cover isn't mine. Also, all of the characters aren't mine. I'm just giving them the credit even if I don't know all of the creators of the characters.

☆ the book will include sanscest, undertale ships, and (mostly) xreader oneshots. ☆ might accept requests soon! ☆ will NOT be doing incest, OCs, ships I heavily dislike, abusive relationships, etc. ☆ updates whenever I feel like it. ♡ please do check out my other undertale books I put up !!! ♡ if one particular oneshot becomes popular, i might put an actual book for it. ♡ low caps is for aesthetic purposes, but only for the title.
