    Summary

    Berry was at Muffet's that night, the friendly spider monster had asked him to come so she could let him try her new non-alcoholic spider cider. To tell the truth Berry had been getting a little lonely lately. His friend Rus had found someone to dote on and well… his brother meant well but he was hardly ever home anymore. Seems like Slim had taken a shine to Underlust and he was spending most of his time there getting wasted and doing stars knows what with the Lust brothers.

    Berry wished he had someone to dote on. Right now he was just lonely and alone at his house most of the time. His phone beeped and he checked it.

    Best Bro: sssorry bro, not comin hme 2nite

    Great, he shuts the phone and puts it back in his pocket sipping his drink… He almost wishes it was alcoholic so that the burn and fogginess would help him forget how utterly alone he was. He'd try with Muffet or something if he thought the flirts weren't her personality, but honestly he didn't really think of anyone in his universe in a romantic light.

    So there he sat alone drinking through a crazy straw.

    Summary

    Ink stumbled back, tripping on his own two feet as he looked at the chaos that once was Undertale #124. It was in smithereens, the people who had survived were disfigured, mutated by chance. Like someone had just let off a nuclear bomb.

    And then even weirder things kept happening. Dusttale #2 suddenly had a core reset, allowing the Sans to live a normal life again. Food appeared in ALL the Horrortale universes. Underswap had it’s first Murder timeline. Farmtale #178 had a civil war.

    Error came at him in rage, as universes he deleted suddenly rewrote themselves and a different universe was deleted instead. And Dream begged Nightmare to just leave his precious AUs alone. Neither Ink or Nightmare had done a thing.

    Then one multiverse council meeting led to the rediscovery of an AU Dream and him had forgotten about. Fraudtale. It was just supposed to be an AU where the skeleton brothers had odd personalities. But instead all was left were humans, all the monsters’ codes scattered in the void, according to Error.

    All but the Sans.

    And ho boy.

    They weren’t even ready for what hit them once this Sans had escaped the confines of his universe.

    Summary

    Y/N was a single dad. A scientist. And... Kind of an asshole. That's okay though, he tries his best (most of the time).

    Being forced into a job he hates and to resolve an issue between humans and monsters Y/N is thrown into a mess of skeletons, lies and bad choices.

    The skeleton brothers didn't realise what really went on behind closed doors until you showed up at their property. Proving them all wrong about this seemingly safe world.

    Stay safe, don't die and remember, Scientists Don't Always Get Along.

    Summary

    Just a bunch of Sans x Sans oneshots. These are not for people who don't like them. They have rape, fluff, angst, lemons, etc. If you don't like it, don't read it.

    I don't condone any of the actions in this book nor encourage or suggest them.

    I'm NightKiller0185 on Wattpad. My book is pretty much called the same thing.

    Summary

    "Who goes up to their friend that they've talked to only a few times, and just because they know their friend does sex work, they're like, 'Oh, hey, yeah, uh, you wanna do some kinky shit with me? My husband doesn't want to but I'm bored.' Like. In what world. Ugh, mine, apparently."

    While married to Sans for a few months now, and neither of you being particularly the type to have sex all that often, you couldn't help but find yourself more… curious lately. Unfortunately for you, as it turns out, Sans is not the experimental type, so he suggests that you look elsewhere to satisfy this curiosity.

    It's a good thing your friend Lust is willing to help you without hesitation.

    Summary

    If the tags and title haven't given it away, this is a one-shot request book! In other words, I want to write porn and have no ideas of my own. Drop a comment with an idea, I'll consider it, and I'll probably write it if I like the sound of it. First chapter will list what I WILL and WONT write, so make sure to check in on that first.

    Summary

    Reader self harming. Meant to be more of a comfort story with more chapters in progress. The skeletons find out that the reader is harming themselves and they want to help the reader with this. In their own ways though all with the same goal to help out the reader who they care about so much. Too much to let them be hurting even if they are doing it to themselves.

    Summary

    [Y/N], a creature made out of Greed and Lust, has been living among the pitiful humans for years, feeding off the sins that crept off their back.
    Sans and his alternatives personally think it's unfair, but shhh.
    [Y/N] ends up staying with the skeletons due to an 'aunt' that had too much money to spare.
    Also [Y/N] is a porn star, that's it, that's the reason why they're Lust and Greed.

    Summary

    There are only a few things harder than being a single parent raising a child by themselves. Try being a Monster mom with a gaggle of skeletons that are always up to all kinds of shenanigans and that fur’sure is going to be a cat’astrophe!

     
    My first Fic that I’m physically publishing? I don’t know if publishing is the right word……. Lol
    Hope you take a look and give me some feedback!
