The Nicecream guy kept selling, monster kid was playing around, Grillby was cleaning up some spilled ketchup. Even in the Skeleton household, Sans was chillin in his room while Papyrus was working on his spaghetti.

I'm The Apprentice: Underfell Papyrus X Female Reader by JaysDreamCatcher

EDIT: READER AND PAPYRUS ARE BOTH IN THEIR TEENS!! WARNING: BOOK CONTAINS SWEARING/CUSSING AND VIOLENCE Just before she passed away, my grandmother told me about the monsters who lived under Mount Ebott. My mother hated everyone. My father died in the war of the monsters. My grandmother decided to whisper to me: "Promise me, You will find, A better family. One who will love you, No matter their duties. I will love you too, I will be watching you. No matter your choice, Let me hear your happy voice." So that's what I did. Her words went through my head as I climbed the mountain, hoping that a monster could help me. - "Sans flinched as the shouting downstairs grew louder. The ropes around my wrist seemed to grow tighter as I struggled, hoping to break free from the monster stomping up the stairs angrily. As Sans stepped back, his door was smashed open. I took one long look at the figure standing there and instantly knew: this is why I am here." - (SLOW STORY! MANY SLOW CHAPTERS BECAUSE OF DETAILS)(COVER ART NOT BY ME!)

Not all Nightmares are bad (Nightmare Sans X reader) by hunter3love

(EDIT: STORY IS BEING REWRITTEN! PLEASE CONSIDER REREADING THE REWRITTEN CHAPTERS [chpts. 1-31] ON MY PG!) You are a young teenager girl. You have a happy normal life........kinda. You're best friends with the angel of monsters, Frisk. One day you follow her and sans to strange place on accident.You see lots of hers and hims. But one in particular caught your eye. BTW THIS IS A FUCKING SLOW BURN SO STOP WHINING! (Edit: I made this back when I didn't know what I was doing. So lots of the story is very confusing. I will be rewriting this through the summer. I'm sorry)

Stuck Together(Errink) by The_Bi_Marshmallow

(This is the first book I've ever written so the start is probably sucky and has spelling mistakes) I haven't updated this in like a year, planning on rereading this and seeing where tf I might've been taking this. ⚠Needs editing⚠ Error and Ink may be enemy's, and polar opposites, but they are both more alike than they think. After being attacked by an unidentified enemy, both Ink and Error are both badly injured. Once the enemy disappears without a trace, neither Ink nor error can seem to teleport or create a portal out of the anti-void. They now have to work together and find get help in order to get out. From both sides in and out of the anti void everyone must help and research to get ink and error out. Will they find a way out? If so, what happens once they do? Will a truce become permanent? I remember people saying that Blueberry and Swap aren't the same person. But they're actually two different versions of the same character from Swaptale. So initially interpret my Swap sans as whichever design as you want. But the personality is supposed to be of swaps design. I'm just calling him blue. !! TW, this does include the gay and ErrorInk so this might not be for u. This will also includes mild course languages from time to time!! Ships: Errink (Error x Ink) Crossmare (Cross x Nightmare) MAYBE???? (There may be more added on later in the story)

Home (bad sanses x child reader) by catsinboxes17

You were an average kid, somewhat having a older mind than most of your classmates. you had always been into the undertale fandom, and even knew almost everything about the aus and soul colors. while what seemed like a normal day at school quickly turned around after a huge bang struck the class room next door. in this story y/n is nonbinary and 12-16 years old. But more interpreted as 14 I post a new chapter every 3 day and 5 days at the maximum. WARNING: this story will mention some forms of slight emotional harm. And Sexual abuse. Readers be safe. Please if you are in any danger, contact someone. You are not alone. With that aside enjoy the story . This story is finished as of September 1 2022, I encourage you to read my other story "Our Disturbing Love" And in the next month or couple weeks I plan on creating another bad sanses x reader.

Lost Cause by AlexBrant18

Remake since I am not much for the other one, but that doesn't mean I'm gonna forget about it. I didn't post the first one cause I thought it might be bad. If you want me to post it just ask! So anyways... Error had gotten sick of it all, he lost all of his anger for it and during a fight got a giant crack and set a portal to the Void where he died and was reborn as a child and sadly lost his memory. But when he's found things that seemed bad in ones eyes is good in his eyes. -2021 edit- -Grammar errors being fixed -I noticed a hand full of readers are lost or confused about Underswap Sans' and Undertale Sans' nicknames. Underswap Sans- Blueberry Undertale Sans- Blue I am fixing it since I have the free time. Happy reading!

No Empty Promises [Ink X Error] FINISHED by ReaperK

'It's all my fault...' 'Now he's gone...' 'If I would have listened, and believed him....' "I'm sorry," He let out a choked sob. ERROR cried, falling to his knees in his house. The ones he loved most were just taken from him. How could he live with himself? He left for groceries, and when he came back his greatest enemy he thought he killed a few months ago was in his house, holding the ones he loved. On the ground layed the one he loved, dying and becoming dust. "I-Im S-s-So s-s-O-r-RY..!!" He wailed out, dust laying on his lap. Nothing could bring them back, it'd take a miracle to find out how to revive a skeleton after he became dust. And it'd take forever to hunt through EVERY SINGLE AU to find the only ones he loved that were still alive. He LET him take them. But if he went and looked for them, they'd die. He took one deep, shaky breath as he wispered, "I'm sorry...." Then shock took over. Another voice just forgave him. Shakily, he turned around as tears stopped flowing. His eye sockets widened, and he started to sob the most he ever has. "HOW CAN YOU SAY THAT?!" "I LET YOU DIE!" "DON'T FORGIVE ME!!" "I LET HIM TAKE THE TWO AWAY, DAMMIT!!!" -WARNING- Rated R/18+ for Violence, Swearing, and suggestive content. CONTAINS: Deprsssing things, murder and gore, sexual content and more. READ AT YOUR OWN RISK. Cover art does not belong to me, only the storyline and ERROR's kitten. P. S. THANK YOU FOR AAAAAALL THE READS, LIKES, AND FUNNY COMMENTS. IT MEANS A LOT, YO. ~RK
