    Summary

    Papyrus is sick of Sans treating him like a child, and (Y/n) is tired of being who everyone expects her to be. When these two find each other they both immediately hit it off, but will Sans or her family try to interfere in their good times? Probably good thing the Great Papyrus is good at sneaking out and (Y/n) is bold enough to be herself! This story is completely self-indulgent and purely smut based plot (its barely there), but if you wanna come along on the journey of Papyrus getting to say fuck and be an adult strap on in friend.

    Summary

    ‘Soul Tattoos are a normal thing for humans and monsters who have hit puberty and are blossoming into adulthood. These tattoos will vary in color, size, and shape the goal of which is to find the human or monster who shares your tattoo although it may not be in the same location the tattoo itself will be identical. For humans, the match itself is straightforward, and should the bonded pair dislike each other no sever side effects are currently known to happen. However, for bonded monsters there are extreme side effects should certain events happen in the bonded pair of souls. If the human in a bonded monster pair dies when the bond is settled the monster in turn shall die from the shock and heartbreak of losing their mate. In any instance a monster who loses a bonded mate will die not long after their Soulmate, but there is a way to extend this with humans. By having a child with said human making them a mage you will extended your life and theirs preventing a quick death.’

    Trying to turn his life around as a vigilante Dust finds himself in a Soulmate AU bonded to a young woman named Willow. Will he give into the bond or use her? and can he avoid his old life?

    Summary

    (Y/n) lost her job, which sucks. If only she hadn't lost her second job, and apartment, as well! Now all she's got is a camper full of her crap on the back of her truck, and nowhere to go. At least she found this campground, even if it is in the middle of nowhere, and looks like no one has been around it for a while, and a skeleton with a head wound tries to make her into a meal... Rough start to making new friends, but his brother is sweet enough!
    And then there's the other skeletons who inhabit the other cabins, who all look vaguely similar... Their explanation of "cousins" only goes so far, but there are more concerning things to worry about, like how almost every skeleton is trying to get into her pants, their heats, and where her clothes, particularly her socks, keep disappearing to?!

    Summary

    In a universe filled with so many possibilities, you come to realize that life hates you, and your only chance of getting out of it alive, is to accept fate, and just roll with the punches. However, with that in mind, you thought having a soulmate was for suckers, and refused to give in to the scam. But as previously mentioned, the universe hates you, so why not have more than one soulmate they said.

    (Just a bunch of soulmate au's I've thrown together. This is supposed to be fun.)

    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.

A particular skeleton who has already become well off in the surface world offers you a place to stay, not realizing that you come with a twist of magic all your own.

    Summary

    Unlike many other stories loosely inspired by the likes of Skeleton Squatters and the Landlady by Tyrant_Tortoise, the female-presenting reader, which uses second-person perspective, are not from 'this' modern universe at all - not even a variant. To clarify, your home is a sort of mix between conventional fantasy and modern city life, or otherwise considered modern fantasy.

    You aren't going to have a good time.

    erratic updates, since i don't have much actually written down.
