Stuck Together (Nightmare!Sans x Reader) by rainbowlixur

(First wrote this on Quotev loll) Humans and Monsters. Most people despise monsters, but not you. In fact, you fell in love with one. A king. And a Human. Who knew that a monster made of negativity could feel love. Who knew a person could love someone like that. Who knew that you being a negativity battery, would lead to a love story. Who knew that *he* would fall for someone as simple as you. #3 in #nightmare - 5/23/22 #3 in #xsans - 5/23/22

Conduit Tale-An Undertale Fanfiction Novel by Serena_Walken

(Complete)Hopeless and in despair, Sans never thought he could escape the resets and continues caused by FRISK that tormented his life. But, when he thinks the kid is possessed and stops FRISK once and for all he finds out ... that he never really knew anything after all. No more resets. No more saves. No more hiding. Life will never be the same for the Underground. Souls and Science can be an unforgiving bitch. Relationship: Because of the nature of the way this fanfiction works, there are several Frisks. He knows all of them, but Sans only falls for one, and she is definitely over the age of 18. This doesn't blossom until some time later though, as this is way more than a sweet romance. Buckle up for some tragic dramatic scifi-twisting to the fantasy world of Undertale!

Resets (Sans X Reader) by Memovie360

The humans sealed the monsters underground with a magic spell, after a long war many long ago and thats where they stayed until about a hundred years ago. The monsters had broken the barrier, and the humans were just beginning to get used to the new creatures roaming alongside them. This had caused havoc on your family, your parents hated you, and each other. It all troubled you, so you decided to end it. You stared at the hole leading to the underground, you closed your eyes and fell forward, but what happened next left you wondering, bewildered beyond compare. Now that you have the option to reset, your deciding if you should end everything, but you knew he'd remember. You knew it would phase him, but then you realize your not the only one with this power, and must stop them from misusing it. But will you be able to? Read to find out. (Cover created by me, story may contain a few slightly graphic scenes but anything erotic will not make its way into the storylines, minor tigger warning, suicidal theme IS inside this story, please continue reading, updates weekly, also READ THE PROLOGUE!!! It has background info that is relevant to the plot line)

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.

Fight or Mercy | Underfell x Abused! Reader by YuniccAfton

[2nd book] ((COMPLETED)) {Undertale AU - Underfell} [WARNING:ENDING AND PLOT IS VERY CRINGEY] "Long ago, two races ruled the earth, the Humans and the Monsters. One day, war broke between the two races. Many have fallen to serve their kind. Years later, the humans were victorious. With their magic, seven of their strongest wizards sealed all the monsters underground with a magical barrier. Only a human soul could pass. Mt. Ebott 201X, they say those daring enough to climb up the mountain.... never return. " "Leave them, Y/N! Run! " ___________________________________________ I'm a Undertale addict. I freaking love the story line and characters! One of my favorite AUs is Underfell so I'm finally making an X reader. Also, if there are wrong spelling or grammar, please tell me. I'm using GoKeyboard. Enjoy my Crappy 2nd book!

The Fallen One by NinjaGamerGirl333

You have fallen into a strange world... will they be friend, or foe? This is an underfell story, so I hope you enjoy! Also, I will be using the pronoun she, but for all the male readers, just replace it with he. Sorry if this is an inconvenience, I just think it would be easier to write that way. Y/N ~ your name E/C ~ eye color H/C ~ hair color S/T ~ skin tone Leave a comment, and share this story! I will try to update at least every day, so there will be almost no wait for new chapters. ~NinjaGamerGirl333

Underlust sans x reader ( some lemons 🍋) by kirishimas_croc

All the monsters have been released from the underground but what happens when creatures full of lust meet some smexy humans Note: was originally inspired by written love on quotev BUT does contain a plot COMPLETELY different to it so if you have the audacity to comment about this READ THE FIC FIRST and then tell me it's similar to something you have read before

Stone Cold Pacifist (Horror Sans x Reader) by ReapingZen

PLEASE READ BEFORE GETTING INTO THE STORY. Your name is (Y/n), and you play the role of an unusual pacifist. In the story of Horrortale, your unique soul allows you to see WD Gaster who no longer holds a powerful connection with the underground due to the inactive core. After your parents are killed, Gaster makes a deal with you. He will help you extract revenge on your parent's murderer, and in return... you were going to fix the core in the underground. While Sans failed to do it when everyone went insane, you knew what you had to do because well. The creator of the core told you everything that you needed to know. The real trick isn't the resources that you've been gathering during your time on the surface for the job, it's the things that are in the underground that you have yet to obtain. While it is true that you have a lot of experience with fighting and a high amount of LV thanks to Gaster's guidance... you now decided to stop killing, and start saving. ...... But can a stone cold pacifist truly manage her way through Horrortale? Okay, a quick note. This story is rated mature, blood, gore, some more sensitive things that you might find extremely suggestive. Since people are enjoying my Nightmare x Reader story, I decided to do a little bit extra. My updates with this book will be a bit slower. (Totally didn't write this story because I wanted to do a drawing of horror for the cover.) This story is kind of a slow burn, but unlike my other story, the reader is no pushover. Like in the The King's Queen, the cover DOES belong to me, so please do not steal it, etc. Remember these important keys when it comes to reading the story! (Y/n): Your name (E/c): Eye color (H/l): Hair Length (H/c): Hair color (S/c): Skin color (F/c): Favorite color

Flowerfell Sans x Abused! Neko! Reader by Suki004

I made this book for @KawiiPotao6678 they have never read a flowerfell x reader so I made this book for them. But all you other people can enjoy as well. Sorry if some of the information on here is wrong I am not very familiar with the Flowerfell AU. I will look up what I can and learn more about it while making it. I will also fix what mistakes I have made because some people are so picky about spelling (not saying any names). I own nothing but the story!!!!!!!! I don't own you!!!!!!!!! I don't own undertale!!!!!!!!! I don't own Flowerfell!!!!!!!!!!! Nothing is mine!!!!!!!!!!!!!

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!)

An Oath of Mercy || UnderFell Sans x Reader by StrawberryMilkSnake

One clumsy moment and a broken leg are all it takes to leave you at the mercy of the very edgy and very hostile monsters of the underground. Thanks to your knowledge as a doctor (and oath to do no harm), you're able to convince the Great and Terrible Papyrus to keep you alive. But how are you going to find your way back to the surface with a bum leg and a short skeleton that doesn't seem to like you? | - UnderFell Sans x Human Reader - Enemies to lovers but Fell is the only one hating - Your leg privileges are revoked, and Fell needs to wash his mouth with soap - Flowey is an equippable companion and decides to help you cuz he actually gets something out of it - My own interpretation of UnderFell (tho from what I've seen it doesn't really have a narrative anyway)

My Fault - Underfell Fanfiction (Sequel to Your Fault) by DragonzRawesomE

{COMPLETED} It has been just two weeks since the event that changed Papyrus' life forever. Too late, it seems, he realized what he had. And now that it is gone, he has fallen to pieces. How, or if, he will be able to cope, he truly does not know. And as if that wasn't enough, there are countless mysteries in store for this burdened skeleton-- coming from people he thought he could trust, and in places he thought that he knew. Will Papyrus ever be able to solve the mystery behind this devastating chain of events? Or will he, too, fall prey to the ever-expanding void that is engulfing the souls of himself and everyone around him? PLEASE NOTE: This book is the second in its series. It contains major spoilers to the first book, as well as this book may not make much sense without having read it first. So, if you want to keep the excitement of the first book without any major spoilers, I HIGHLY suggest going and reading that first. It is titled Your Fault.

Broken Souls 1 - Sans × Monster!Reader COMPLETE by NeonVixen

Instead of you being a human, you're a monster in the Underground. I will continue to go back and edit or merge parts until I have completed the story. Parts that I am actively working on will be labeled "[under editing]" Also, art cover is an action figure off of fangamer.com. they have more action figure characters that are so cute. I am not affiliated in any way with fangamer.com. This is my 1st story in a VERY long time. I like to do things a little different as far as reader inserts go. 1. Instead of Y/N for your name, I use _______. Why? Because when I'm reading a story and read Y/N I think Y/N and then have to remember the name of the character I've made in my head, where as if I see _____, I immediately replace it with the name because there is no word for me to read. Love it or hate it, comment. I can be persuaded if the masses disagree. 2. I don't do H/C, E/C, etc., because it does the same thing that Y/N does for me. Instead, I will be as vague as I can on insert character descriptions giving the reader more freedom to imagine what they look like without forcing it down their throats. 3. For undertale specifically, I am more inclined to make monster!reader inserts, because that makes more sense to me. This will not always be the case. If the masses prefers human!reader inserts, comment so that I may be persuaded to do so. Also, feel free to ask for requests. The more requests I get, the more inclined I will be to do more stories. They don't just have to be undertale related. I will give you credit for any requests at the beginning of the story.
