AU Sans x Reader oneshots 2(Requests closed) •~complete~• by ReaderReads10

I couldn't just leave you guys there! Enjoy the book! Feel free to request

мułт¡-ƒคหdσм σหε รнσтร [Finished And No Longer Accepting Requests] by XKawaiixreaderx

I am no longer taking request! "This is a one shot book where you'll find different fandoms that people have requested. This book was created when I was younger and just starting to write things of fiction. This does have cringy parts and the smut is a bit weird. I'm not proud of some things I've put in this and I've deleted problematic posts that I made (nothing too bad tho! Just some that come off as creepy) Overall it has its comedic parts so I hope you'll enjoy the chaotic trainwreck this book is."

UnderTale Universe One-shots by aholmes405

HEY GUYS!!!! This is a book of one-shots obviously.This will have one-shots of all different universes. (underfell, underswap, undertale, etc.) I am taking requests and would love to do anything that makes you guys happy! Credit goes to the respectful artists.

A Book Of UnderTale Oneshots But It's mostly Sans suffering by JDStudios

~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.)

One shots. by wearelazytoday

What the title says. Mostly about Error, because I cannot stop thinking about ideas regarding him... Either way! One shots! There will of course, be one shots about others, not just Error. Uh- ships are mostly after death and destructive death, but if there are any recommended ships I will gladly try some of them out! Ships (if there are any) should be written at the top of each oneshot, if there are no ships in it, it should say "No ships." Any pictures or art used in this book do not belong to me. Nor does the cover art. *cough* UnderTale belongs to Toby Fox. I don't know why I'm doing this- help- Also. Personal favorite is the Encased in Glass one shot.

Sanscest One-Shots (old) by NoneSoupForYou

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.

Error's book of angst and fluff (finished) by Leffee

Please for goodness heavens, don't comment if you're really young, I had to delete enough of cringy comments. Also please don't leave any suggestive comments, there's a reason why this book doesn't have lemons (aka I'm sex repulsed). Just some one-shots about Error!Sans. Mostly fluff and some angst. Basically me throwing here whatever comes to my mind. Error is short, not because I said so, but because it's canon. In some chapters ships are directly shown, while in others they're not. If that's the case then they're probably friends, but there's nothing stopping you from seeing them as a ship. (Cover belongs to yufy01 on tumblr)
