    Summary

    You’ve lived a hard and… unique life, you will admit. Through this, you had somehow managed to become friends and roommates with two skeleton brothers. Okay, great, this can be handled. They're quirky in their own way, and you quickly grow close to the both of them. Okay gr- oh. Oh fuck. Well, this is awkward. Multiple Sanses are now in your world, and it looks like their staying in your house for a bit. Okay, this can’t be that bad… fuck, I jinxed it. Because guess what? Whether you like it or not, it’s a Reverse Harem now. Okay, it’s time to get guided through the rest of your life with the help of the Undertale gang, a skeleton shattered through space and time, and well…. a lot of Sanses too. Very awkward indeed.

     

    Currently being rewritten to be less cringey and actually line up with my current plotline instead of being all over the place.

    Summary

    Just my own interpretation of Sans' death in Undertaker's Genocide route as to why we don't see him die onscreen.
    What if his father, Dr. Gaster, had a part in this, had a part in helping him, had a part in the fate of every monster in the Underground?
    Note: inspired by another story, idk the name

    ☆ Story #194: Hanahaki Disease #1: Stargazer Lilies

    The Hanahaki Disease is an illness born from one-sided love, where the patient throws up and coughs up flower petals when they suffer from one-sided love. The infection can be removed through surgery, but the feelings disappear along with the petals.

    Papyrus is in love with Mettaton...re!

    Summary

    This story depicts the struggles of the monsters after moving to the surface. The coldness they were met with and the problems they have to deal with after encountering humans. Mostly Sans and Frisk centered, it follows the evolution of Frisk growing up as an ambassador, and Sans' feelings and comfort around humans. Just like in today's society, we are having a hard time accepting anyone that does not look or think like us, we tend to isolate them, make them an enemy, judging on looks, race, ethnicity etc., in this case, the monsters became the race that almost everyone decided to label as enemies.

    Penetrative sex on reader.
    Gaster has a knotted penis.

    Summary

    You've done everything there is to do in every timeline, over and over and over again. Life is monotony. There's only one entity missing--the entity you've dedicated your life and research to finding. You both fear and love him.

    Reader is ambiguous gender (no mentions of genitals).
    Mild sexually implicit themes but no outright sex.
    Reader's desire to "not exist" is intended to follow the implications of non-existence in the UT universe, ie. Gaster in the void, and not intended to imply suicidal ideation. However, if you are highly sensitive to such themes, please use discretion.

    What happens when a good underfell Papyrus meets a not so good version of himself?
    Edge, a fell papyrus, has been living with his boyfriend Blue in a peaceful timeline for a while now so what happens when another tall dark skeleton shows up? Instant hatred.

    Summary

    You know, when one dies they expect to be brought to a place somewhere else; another plane that would supposedly to be their heaven or hell or whatever they think the afterlife is.

    When he died, he expected hell, or even limbo, heaven probably was out of his grasp even with that bizarre stunt he last pulled; not meeting a familiar melting figure in the void of death and reincarnating as a flaming baby.

    His memories have blurred, he can't remember much of his personal life but what he does remember was playing a certain game before things went to hell. Now in his new life, he has to deal with being an entirely different species, a protective incendiary older brother, the ghosts of children, a psychotic flower too curious for his own good with a matching teenage ghost that fully reawakens when Frisk falls and a new sense of pyromania.

    Things had gotten worser and weirder when and after The Accident happens. And Gaster was not making things easier for the both of them. Nothing is making sense but at least when the resets happen he'll have Sans as understanding company; now if only the skeleton would stop being weird.

    Summary

    Everyone is born with a mark that connects them with their soulmate. Some are super clear, giving you the name of your soulmate, while others are just pictures and you have to rely a bit more on your gut to find your special someone. In this world their are both monsters and humans. Time period wise it's more of medieval times, with lords and castles and all that good stuff. This is completely because I have no self-control and may be addicted to this game...
    ((Technically this is a Papyrus/OC story but you can substitute for yourself if you'd like :3))

    Summary

    Lancer de le Pique, the Prince of the Dark World, is sprinting through his life, hiding from his father. Not like there’s anything wrong with him. He loves Lancer, really. Otherwise, he'd be out on the streets. He just wants to toughen him up. And it’s not like a few punches or whips can bring Lancer down…right?
    But one night, a Lightner falls into the Dark World. He has terrifying bone for skin, voids for eyes… and a hoodie, a smile identical to Lancer’s. It started with prejudice, then questions, and then handshakes, and then a little noogie or two. And maybe… just maybe… the start of a new friendship. A friendship that may soon lead the fate of the entire Dark World.

    Summary

    It all started with a paper. A simple college essay. Who knew you'd be trying to rescue someone who's trapped in the Void itself, let alone maybe having feelings for him too?
    You didn't really plan for it, nor ask for it. Then again, who really asks for anything to happen in their lives?
    You know one thing, at least. You don't regret the choices you've made.
