    Summary

    Reader leaves home to chill down a little and she falls into the Underground. Sans is there, ready to meet the anomaly of the timeline, but he feels like his soul is calling for her. He knows there's something wrong. Where is Frisk? Why is (Y/N) there instead? Why did she fall so late? Why can't he get the fog out of his skull and remember?
    He needs someone he can cling to. But he can't let himself. Not yet. You'll help him and the entire Underground lead to a fair life on the surface. You'll make sure of it. And you'll lend Sans your shoulder. You'll slowly convince him he can lean on you, past his shell.
    The only problem is... what is he hiding from you?

    Man I'm sorry this was an awful summary idk how to do this

    Summary

    Fired from your job; unable to pay your rent, nor your college fee; possibly going to court for something you didn't do. That's how Frisk finds you. Or, rather, that's how they bump into you, run up Mt. Ebott and make you run after them. And now you're in the Underground with a child, and you are pretty sure they adopted you as their brother. And you have magic?

    or,
    Reader falls into the Underground with Frisk and has to deal with monster's freedom, his own magic and resets.

    Summary

    Working full-time isn't easy, but it's worth it. What's not worth is the mess you leave at home, the late visits to the market, or wasting free days just to do housework. Since a kid, you hated doing chores and always wondered if there's a way to escape from it. And what about a househusband? Or better, a lot of househusbands so they don't overwork themselves? It sounds dumb, was what you thought...

    Summary

    The paradox of freewill states that if an omnipotent being could exist, one who knew the past present and future, that freewill could not. The existence of an omnipotent all knowing being would determine that all choices and decisions were predestined and no matter how autonomous you may feel you are you truly are a puppet to fate.

    After the monsters were freed from the underground you had been plagued with strange dreams, light headedness, nosebleeds that bled black goo, a voice you can't understand reverberating through your head. You have knowledge of things you shouldn't know. Haunting probably wasn't the right word for it. It felt more like only half of your body was being possessed by an intruder.
    The paradox of freewill states that if an omnipotent being could exist, one that knew the past present and future, that freewill could not.
    W.D. Gaster was the omnipotent being in this equation.
    OFFICIALLY DISCONTINUED
    And you weren't satisfied being a puppet anymore.

    Summary

    You are a college student that just want to get yourself together, get a degree and make money enough to live alone in a cozy flat. But what should you do when you struggel with studies and different jobs while sharing a life with skeletons whom seem to don't like you?
    Determination won't be enough to keep living in this hell. And a friend of yours make sure you remember that everyday.

    Now the breaking news:
    - I love comments
    - No beta reader
    - English is not my mother language
    - Long time until next update
    - I am as bad as Asgore to name and nickname the characters

    Summary

    Kinktober 2021 is here, and so are some horny skeleons!
    --
    the reader can be male, female or unspecified (based on the chapter you are reading of course) :D
    -
    There is absolutely no rape or dub-con, there may be con-noncon.
    --
    All the characters are based on my versions, such as the 'home for lost souls' boys or the 'a tyrant and an addict'. even the AU's that aren't in the canon story line of either of them, because this is a spin off series and not at all canon to my previous works.

    Summary

    It was cold, so cold, too cold.
    You were draining, slowly, as an orange whose juice would be taken....
    the warm juice, the warm and red juice. Leaking, through a dam's rift.
    You felt like an empty Shell, empty of what it contained, empty, too empty.
    You couldn't see anymore, couldn't hear anymore, couldn't feel anymore.
    You were surrounded by emptiness. An emptiness that took everything, and nothing at once. Then, Came the light.
    and you were no longer, empty.

    Or when a reader who got not memory except for Undertale and common sense, wake up as the most mysterious skeleton of the band ; W.D. Gaster
    It's way before Frisk fall underground, but after the Asriel/Chara incident.

    Summary

    You were pushed down into the abyss with a valuable ability, and a pivotal mission:

    Collect their souls, as they have with ours. For our country.

    Will your morality overrule your sense of mission? What is with this country, and what secrets does it hold? What led to you falling down that wretched hole?

    ..and who is that tall, lazy-ass skeleton fucker who looks like he doesn't give a damn?

    Summary

    Reader is a bunny (mom)ster with a load of poor choices up her sleeve.

    One is engaging in a shitty rebound relationship with a bad-tempered, human man and nearly getting herself killed when the truth comes out.

    Another is hopping right on her savior's lap and kissing him after a few too many drinks.

    And yet another is calling her ex when being more than rightfully rejected by her savior.

    The list goes on and on and on.

    Summary

    When you moved in with your friend from middle school, you didn't expect this to happen.

    It started off well.

    Her soulmates were fine. Some rougher around the edges, but they all seemed like good people. You got along swimmingly with a lot of them.

    Until one day, they all started hating you as if you had murdered someone.

    You were subjected to cruel comments that broke you down until you were a shell of who you once were. You force yourself to suffer through this until you could move on.

    Until then, you will have to suffer.

    Summary

    I’ve been in need of some non-binary readers in this fandom. I would’ve thought a fandom with a gender-neutral protagonist would be more open to the idea of gender neutrality, but it seems like the majority of fics are gendered.
    WARNING: shitty writing.
    I’m new to the writing stage, and if you wanna help me get better with grammar or phrasing, feel free to! :)

    Summary

    C pouted. “You two never let me do anything. It’s not fair.”
    Ink and Cross traded a look. “Oh nooo, it’s almost like the last time we listened to you it caused the X-Event,” Cross said snarkily.
    Ink snorted. “Nice. But do we have a deal?”
    “Sure, we have a deal. I needed to get back in Nightmare’s good graces anyways.”

    Summary

    What if Frisk wasn't the final one to fall down to The Underground? What if you were the one instead? Down and out of luck, you thought that disappearing in the mountains and never coming back was your only option when you couldn't see any, but fate has other plans in store for you when you decide to drop down into a dark land desperate for escape.
    Although ready to leave this world, your heart fills with determination.
