Underfell Stories

‼️⚠️WARNING: MATURE THEMES SUCH AS SEXUAL ACTIVITY AND TW'S PLEASE READ AT YOUR OWN RISK⚠️‼️

You have a twisted life, and you're in an orphanage because you're parents died in a terrible car accident...or at least that's what everyone says. You go to this annoying school called Pinecrest High. Everyday, you go to a tree to help you with your nerves. And one day, a certain skeleton saves you from certain doom. Yes, this is an X Reader story. This story updates slowly and I need lots of time to think about the plot points. I'll change the story summary when the book is finished to make more sense. Just please enjoy the story :3

In a secluded part of the underground a tower exists sounded by a giant stone maze sounded by cavern walls in this space those that live in it consider it a direct world from the rest of the Underground and those that are in the maze thay have no way to escape or at least that's what they thoght

A sprawling collection of Sans x Male Reader and Papyrus x Male Reader one-shots, each exploring different universes, scenarios, and emotions. From lighthearted dates filled with laughter and teasing, to dark, intense encounters in twisted timelines, these stories dive deep into the bonds between you and the beloved skeleton brothers. Whether it's classic Undertale, an AU like Underfell or Swapfell, or even modern-day alternate worlds, each chapter brings a fresh take - romance, angst, action, or even a bit of smut, depending on where the story leads. No two stories are alike, but they all share one thing: you at the heart of it all, finding love and connection with Sans, Papyrus, or even both in unexpected ways. Perfect for fans of slow burns, wild adventures, and multiverse chaos, this anthology will make you laugh, cry, and maybe even blush. 💀✨ Your story. Your choices. Your skeletons.

A fox hybrid meets some skeletons and some fall for her, she meets Frisk again but something drastic happends to them, she ends up being distant once more. What will happen next?

Summaries... my worst nightmare... Anyways, the characters of this book are not mine, they are from their creators of Undertale, Underswap, Underfell, etc. etc. Ever since the Alternate Universes of Undertale found out about each other, they started to come together in one place that lets all monsters from all Universes in. Only a few do stay there. Cover Art was created by me, DO NOT USE IT FOR ANYTHING ELSE, thank you.

I got tired of bad or short one shots and decided to take the writing into my own hands. Please suggest more ships at any point in my chapters. I want to write anything you want. This will also have a mix of fluff and smut in it, so there may be two chapters of one ship. Ship names will be at the beginning of chapters, as well as if the chapter is fluff or smut. >-< #35 Selfcest 13 June, 2022 #38 Selfcest 20 Oct, 2021 #67 Selfcest 5/3/2021

Sans finds himself in the UnderFell universe when something goes wrong with his teleportation magic. Finding himself next to the door where he speaks to the mysterious lady who makes him laugh, he thinks nothing of it. However, noticing something different, he becomes unsure. That is until he meets a mysterious look-alike blocking his path... NO SMUT / LEMON Maybe fluff ;)

You're a 16 years old girl (Sorry guys). You live alone. As a Graceling, you're despised for your powers, but you've never let that bother you. Alright, maybe it did bother you. Your whole world changes when your bully gives you a box with no explanation. Also, the picture for the cover isn't mine.

Just something I wanted to try. Sorry if it's bad. This will contain mature content. None of this is mine. All rights go to those who owns them. You are part monster and human. You can form into a wolf. You have a adult wolf size and a cub form. In your wolf forms you can't talk to people. The only way to communicate with anyone they have to be a part of your pack they have to be blood relative or a mate. And when you change between your human and wolf your clothes do not magically stay on. You are butt naked. Only cuz I think it stupid and makes no sense you would have clothes on.

Originally from @OitsyoboiNm. After countless genocide runs, classic couldn't take it anymore and was getting really depressed. Now it is up to ink, dream and Red (Especially Red 😏) to get him on the right path again. Will they be able to save him before other skeletons get there way?

Перед прочтением прочтите первую часть. После сброса пройденного на пацифиста Фриск начинает свой путь заново. Но будет ли это вновь пацифист? И какие теперь будут отношения с Редом? Встретит ли шатенка вновь Нину?

Just fanart that I absolutely LOVE (I lie, I love all the fanart I receive!)

i know the wallpaper is unrelated.. i need to search for the right wallpaper sorry! so basicly its about you prentending to be a boy at a school... since your guardian enrolled you at some school with full of boys....but you need to finish your school year! will the sanses will notice that you are a girl? Females Only sorry...

Ehhh...I was bored...? *shrugs* I own nothing obviously. Just sharing amazing artwork. I'll add to it as time goes on. No rush... It's not in any particular order so... *hides in a box* Not all pictures are child or innocent cinnamon roll appropriate. You have been warned.

It's been another Reset. What happened this time? Frisk claims to have not put in a reset. Who did the reset? Also, Ashia has gone missing. Where was she? But, there was reports on monsters going missing recently. Then suddenly, Ink goes missing as well. Sans has a hunch that Error is all behind this. It's up to Sans, Geno, and Fell to reach Ashia and Ink. Can they rescue them before they become... ...CoRrUPTeD?
