    Summary

    Despite good intentions (or slightly selfish ones), Asgore Dreemur hasn't always had the best behavior. But at least at this moment, right now, he hopes he only cares about her well-being, and the well-being of the make-believe family she has made herself. Keyword: hopes.

     

    (TLDR: Toriel doesn't love Sans for the right reasons, and Asgore has been stalking her for years.)

    Summary

    Frisk falls down bla bla bla.
    something somthing love- friendship... power....

    ***

     

    I posted this before and orphaned it- it was meant to be an intro to a soulmate AU for a shameless sans/reader fic but that fell off the rails and I removed both.... Now I feel this is just a good bit of fluff that deserves to exist on its own. Might give that second fanfic another shot- feeling cute might delete later lol

    Summary

    In an Undertale alternate universe called Underlust, where almost every monster is hypersexual due to being injected with lust in order to increase the monster population, Mettaton is an outsider. As a ghost, he was not injected with the lust substance, and he is completely different from everyone else because of this. He feels out of place as a bookworm and nerd who has little interest in sex, and he feels lost because his quiz show is unsuccessful in the Underground. But Mettaton might not be as alone as he thinks. A certain skeleton loves Mettaton's show and wonders if anyone in the Underground shares his rare capacity to value love outside of just sex.

    This story contains graphic descriptions of sexual assault, anxiety and other mental illness, self-harm, and lemon. Because the plot depends so much on these triggering topics, it would be difficult to provide in-text trigger warnings every time something comes up. It would also be really hard to understand the story without reading those sections. If you don't feel comfortable reading about those things, I’d highly suggest not reading this story.

    Disclaimer: I do not own Undertale or Underlust!

    Summary

    It was just a normal work day for Y/n....
    Untill it wasn’t.

    (This is 100% self indulgence. What follows is bullshit I find funny or interesting that I can't put in my other stories)

    (....Maybe I should actually make a proper summary because this is becoming a whole thing now....
    ....it's mostly reader and Red centric....there, I did the thing)

    Summary

    You, the reader, in this case Bea, are obsessed with Undertale, and a short skeleton. But once the monsters break the barrier and publicity spreads of their arrival, it's suddenly pertinent to keep the monsters from ever finding out that their lives were a video game. You still play the game avidly, despite the unknown effects; however, when a certain pair of skeletons become your roommates, you discover pretty disturbing things about the game you're playing. However, will you keep playing the game under wraps in hopes Sans will never find out? Or will you be forced to give it up?
