I noticed there weren't any SF Paps x readers so I decided to make one,and there might be some visits from a radtastic skele! 'I bet you're right home slice bride slice!' Fresh Sansy said wiggling his eyebrows, 'Bwahaha!I can't take you seriously when you do that,hope you enjoy the story!' I laughed.

The old bookstore wasn't your home anymore, you finally realized. It was with them. It was with him. (Sans (Undertale)/Reader. The story takes place in second person view. Reader is not Frisk!) (art is by @Elmer_Heiji on twitter)

You have been in the underground for about a year now. You live with Papyrus and Sans, but things aren't going too well. Sans sets you up with your crush, Grillby, without you knowing. Will he return the feelings?? Or will he leave you in a worse state than you were before you met him...

What happens when Y/n wants to explore Mt.Ebbot with her sister Frisk? Find out in this new story! This is my first book so please no bad comments!

You woke up on bed of golden flowers without having anything to remember. Going to an adventure where you met with many monsters to go home. Easy, right? Not really, actually but anyways! - I do not own any characters from undertale -i did this only for fun, don't judge me -this story is abit (alot) angsty so be prepared~ -Chara is evil(sorry i just had to-)

Anyone is welcome to join this little RP for Undertale! Never hesitate to ask if you want to join! ~~~ Cover art by zarla-s!

(Cover Art is not mine.) You don't remember who you are, or who you used to be. You've woken up in an abandoned costume shop with amnesia, after the second human and monster war. The monsters were victorious this time, and practically all that's left of humanity is trapped in the Underground. You find a journal explaining how to survive trying to live among monsters, and you become aware that you are one of the less than ten humans still on the surface. Deciding to live among the monsters instead of risk it in hiding, you enter a monster-filled city, and meet a certain skeleton. Undertale: ©2015 Toby Fox. All Rights Reserved.

Sans has lived through countless timelines. He's seen the kid make friends with everyone, only to give up in the final moments. He's seen the kid killed, over and over and over again. Sometimes, he'd even done the killing himself. And no one ever remembers. Not even the kid herself. It's an exhausting cycle, one that never seems to end. But there's something different about this run. Another human's fallen down... the kid's sister.

Finals are coming up and you're determined to ace them, and that means that you enlist the help of your best friends, Sans. Well, his full name is Gaster!Sans, but you just call him G, it's easier. Anyway, it would all be fine... if you didn't have a gigantic crush on him... and if he wasn't a, well, let's just say he 'gets comfortable' with a lot of different girls. Yeah, things get a little messy. A lot of sexual innuendos Sorry... Just, yeah, sorry

A long time ago, monsters and humans lived peacefully. Then, war broke out. The monsters were forced underground, and the humans were left above. A killing machine was created, to destroy all the monsters in the underground. This is her story. Asgore is the prince, who lives in the palace with his father (Nazur) - who is on the edge of death - and his wife (Toriel) and son, Asriel. Toriel and Asgore are about 20. Gaster and Grillby are buddies around 19. Sans and Papyrus have no set age, they're experiments. If they did, they would be 17 or 18. Reader-chan is 18.
