    Summary

    Kinktober 2021-2022-2023 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.
    not only kinktober but also any short sexy time works i make as well.

    Summary

    Edge, a dom with years of experience under his belt, has been having second thoughts about his role recently. More and more the idea of being a sub calls to him, and despite his fears he is drawn to the role. But a sub needs a dom, and who better than the enthusiastic, kind dom he'd been talking to for months online, the one that makes his soul race every time they talk?

    He didn't expect it to be Papyrus, though.

    Summary

    "Don't be surprised if this doesn't end the way you want it to."

    "Oh do not worry, it will. This is what brought them here, and if it wants them back, who am I to stop it?"

    He only worries for their safety, but who is he to judge the other's decision?

    A malfunction of this magnitude is improbable, but not impossible:
    That was when they saw it, two beings, one larger and one smaller. While the machine had once spat out skeletons on a regular basis, it was deemed derelict after the last two came through over 6 months ago. It seemed other universes lacked the means or the will to travel elsewhere, thus it was shut off for good; the safety of the skeletons and the city was considered more important than the possibility that untamable beings traveled through. How could it have produced two more if it was unplugged? And why had it exploded in the first place, it was unpowered! All of their minds filled with fear, curiosity, and gloom.

    Summary

    (TOLD IN YOU/YOUR)
    A reaper, a few gods, and a bunch of skeletons.

    The life of a reaper wasn’t boring to her, everyday she would gather souls and lead them into eternal rest, and repeat.

    She watched creatures and Humans die, easily surpassing their lives and meeting once again in the underworld - or when she is evaluating their lives.

    One day, Y/N was told she was moving areas. A whole new continent in the world, in a city known as Ebott, where monsters had emerged from the mountain nearly five years ago.

    What happens when a workaholic with stubbornness to boot moves in the neighborhood, with skeletons causing havoc in her life?

    And, uh, well.. let’s say she isn’t the easiest person to get along with.

    hello, hey, hi Oki, so you know me by now. If ya haven't already I highly recommend reading Kamisori (Zombietale). even if the story and plots are completely different maybe you can get some sense of (a few) of the character's personalities.

    Zombietale is a really good fic! I love it!

    Summary

    What if you also got into an otome game that you recently passed? So you don't know either. God, you're not even the protagonist, but just a background character who flashed through the story a couple of times!
    "... Although, it's even better..." - you thought. After all, it's better for you to watch everything than to participate in a love drama.
    However, things don't always go the way you want them to. And now love interests are sticking to you
    "Leave me alone! Go to the protagonist!"
    "Baby, we only need you."
    What's wrong with this game?

    Summary

    Sticks and stones are worse than words and you have the text message to prove it. Now your soul is literally broken and your very name has been seemingly erased from the collective vocabulary of the universe. At least there is an adorable skeleton child to distract you from taking care of yourself.

    Summary

    Sans was taking a nap one day at his sentry station in the underground. He didn’t expect to wake up on a strange train with a strange child talking to him.

    He also didn’t expect being forced to kill strange versions of himself. It reminded him of someone he heard a long time ago.
