    Summary

    Just one of your generic ABO Island fic, with a bit of a twist of a female skeleton who's tall than all the Sanses yet smaller than all the Papyruses.

    + Thanks for reading! Hope you have enjoyed it so far! +

    Summary

    Stretch has a condition that puts him in a low-level sort of heat constantly. Usually, he's medicated and fine--
    And usually, Boss isn't around.
    Of course the one day he forgets to medicate, Boss happens to be there. Instead of making a fool of himself, though, Stretch finds himself on the receiving end of a confusing but welcomed performance. Stretch is more than willing to act the comic relief, but can Boss fill the role of casual lover, or will it be a more challenging part than either of them thought?

    Summary

    Four AU’s have come to a happy ending on the surface. It is a new beginning for everyone, but Berry is haunted by his past that still clings to him and threatens to pull him back into the darkness, unknown to his now growing skeleton family. The newest skeletons are from the last set that surfaced: Fellswap. They are not going to let Berry be taken. Howl and Daemon, the two newest skeletons, have to dig into a horrible truth and show the world Berry’s past, and with the help of their fellow skeletons, they hope to make a better future for him and all other monsters.

    This is adapted from a role play with GetMcDunkedOn and me (Diyami). I hope you enjoy it.

    Summary

    Co-Creators: StormyFictioners and TempestJewel

    Multiverse Surface AU (Original Sans fixes machines and brings them to the surface) Undertale is the only one of the Universes that have reached the surface.

    Summary:
    Stretch is blind. While everyone in his Universe knows this, he doesn’t want their Alternates to know about his condition. Blue is hesitant to agree with Stretch’s secret, but reluctantly promises not to tell and let Stretch tell them himself.

    Basically a cross AU shipping party that will eventually become smut induced love/angst/fluff. READ THE TAGS, enjoy the story.

    Summary

    Snakehands: this is a bit of a game - Gaylie and Comic4244 have started this fanfic but they will not be the ones to finish it. Coming parts of the main story will be written by the talented authors Diyami and Hailsam. Other talented writers will be writing side chapters that are an important part of the whole series. Expect chapters and characters to have a different feel as each author has the freedom to write what they want and characters and parts may also seem a little different, but it's all part of the game.

    Anyone who may want to contribute a chapter please contact me on Discord at Snakey#2625, especially if you have your own AU.

     

    Summary

    Hailsam: The Underswap universe has a slip in the void. Skeleton brothers are jerked across the multiverse, far away from one another. Stretch takes up the journey to find his brother, and perhaps prevent his world from slipping back again. Meanwhile, Blue falls into Underfell, finds himself perhaps falling in love, and then tragically captures the King's roaming eye. Will Stretch ever find his brother again? And if so...will he be the same Blue that Stretch remembers?

    Summary

    For Anjel_X, who raised up the fact that smol Sans almost never gets to top Bara Red during a heat.

    So I decided I'd knock out a few birds with one stone: Kustard, heat, and all the goodies that come with it~
