One day, Sans fell sick. His sickness came out of nowhere and it cannot be cured no matter how many medicines Gaster gave him. Because of the sickness, Sans stayed still on the bed, just laying down or sitting on it under the blanket. The sickness can be seen from his face, half of his white skull was a little bit darker than the rest. Gaster and Papyrus had no idea what kind of illness Sans has, but they decided to take care of him no matter what, hoping that the sickness will soon gone either because of the medicines Gaster gave him, or disappears itself.

But alas, The sickness gotten worse...

Origin Of The Bros (Fontcest) by BubblyShip

(Toby Fox owns UnderTale, the cover is my own art, and I'm trying out unusual ships and Fontcest is the next in line following Sansdyne. Why not?) Papyrus used to have trouble making friends, so his Dad decided to new addition to the family would be a great way to make Papyrus a perfect brother! Or, if things spiral out of control, a perfect boyfriend. Gaster really should have considered making Sans' personality not fit so perfectly with Papyrus' before he created him.

Determination - G!SansxFrisk by Toasty-Writer

Frisk just wants to save monster and humankind, but does she have the determination to do everything she wants? Especially as she has now been blamed for the terrible crimes committed by her sister. G has stopped caring, but can this infuriating woman who becomes his neighbour pull him back into the world and seek for justice again. I'm so bad at descriptions :/ I'm delving headfirst into fanfiction. You guys may not like this story or even read it but I'm going to try. This is a Gsans and frisk story, there will be an attraction between them but it may be slow :P I do not own the characters or their respective AU's. I'm simply throwing my own twist into the mix hoping you like. I do not own any of the art featured in this book, they are just all amazing. Will involve some moderate language, violence and trigger warnings, hence the mature rating, I will warn at the beginning of chapter if there is a trigger warning.

Reset (Sans x Older!Frisk) by error-code-707

There are some things you just can't take back. No matter how many times you reset. After breaking free of Chara's grip, Frisk decides to do one final reset before defeating Sans or proceeding to the throne room. But some memories last longer than others, and broken trust isn't easy to repair. Female, aged-up Frisk. Starts out canon and then diverges. Eventual Sans x Frisk. Undertale was created by Toby Fox. I do not own Undertale, nor any of the characters. Some violent action scenes. Cover art is by amazing artists at http://www.zerochan.net/Undertale,Fanart and http://www.zerochan.net/Chara+(Undertale),Fanart

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.

What Is Love? by Rosu-chan

For many years, Frisk never once knew about Valentine's Day. What?!! That's probably what you're thinking. Anyways, Frisk has a huge crush on a certain skeleton who's also crushing on someone else. Will she be able to confess her love to him and live a happy ending? Also...Frisk is a girl in this story ;) UNDERTALE DOESN'T BELONG TO ME. IT BELONGS TO TOBY FOX. None of the used pictures&gif's are mine. And that's about it. Plz follow, vote, and comment in my books. I'll be happy to hear from you. Buh bye!!!!

What Lies Inside (Gaster!Sans x Reader ) by Jaethefallenhuman

"You know sweetheart, lying doesn't get you anywhere with me." He said lighting a cigarette and placing it in between his teeth. Vanilla, leather, and smoke is quite the intoxicating smell. "I'm not lying, also who gives you the right to judge if I'm lying or not?" Something flickers inside me, a warm burning feeling that fuels my anger with this asshole. Walking up closer to me he pins me against the wall, smoke dances around his skull in a vary of swirls and curves. "Let's get something straight dove, I am your worst nightmare and I am your best daydream. I can see right through people, ironic right? There's something about you, I know you're hiding something inside." He really is good at seeing through people, but the thing is I'm not like anybody else. The media I use in this book does not belong to me, they belong to their rightful owners! Gastersans is NOT my original character ! He was created by Borurou Undertale was created by Toby Fox Highest rankings #1 Gatersansxreader #1 Gastertale #19 Gastersans

[HIATUS] Don't Forget [Sans x Female Reader] by GabrielXander

You would think that with how shit your luck is, you would've been dead day one since falling into the Underground filled with scary monsters and a few spooky skeletons. However, much to your surprise, that did not happen (yet). You know how you ended up here, but you don't know... HOW. You're actually in the GAME Undertale now. And to make matters worse, there are some people who KNOW. You're surviving the best you can, but things are only going to get weirder from here on out. Gaster apparently needs your help? You're using the DJ to go to different AU's? You are gay now?- Okay, maybe that last one is just a joke, but still! You can only hope that your instincts are enough to keep you alive in these trenches. On God, they tryin' to drown you in this hoe! {Available on Patreon, Quotev, and Ao3 under GabrielXander}

Memories - (Sans x Frisk) by BatBanana

"I feel that I'm living in a dream right now, and any moment I'll wake up and find myself back in another nightmare." I say, eventually. "Welp, if you ever do, just remember, dreams can come true," he tells me, bringing my face closer to his. - Chapter 7 The reset button. Just the word is enough to give Frisk nightmares. Temptation grows strong inside her, but if she were to disappear, would everyone else be saved from the peril that a reset brings? Cover art done by me, and I do NOT own all of the characters in this story. Undertale belongs to Toby Fox, but some of the characters in this story belong to me.
