    Summary

    Nova just wanted to use the machine to find her friends... she never asked to be thrown into a whole new universe. As a cat. She didn't want to be 'adopted' either. By a 7 foot tall skeleton no less.

    [I'll add more later, sorry for the bad summary. Basically my OC fucks with something that shouldn't be fucked and is adopted as a cat by Edgey boi. This is purely self indulgent.]

    Summary

    You and Sans have spent the last five years toiling in the lab on your magnum opus: a looking glass into alternate timelines. But when you test it one late night in the lab, the impossible happens and you are taken into a world much more violent and crueler than your own. Needing to survive until you're rescued, you will have to use all your wits, charm, and determination to convince three paranoid skeletons you aren't insane or a spy. Good luck, doll.

    Summary

    Error won.
    But his victory wasn't what he expected, fused with the lone survivor they fought off the demon that tricked him. But now alone in THE END, they work to rebuild everything they lost, at least until they are offered redemption by a strange entity. They cannot change their fate but if they help an Error from another reality, they can stop the past from repeating itself.

    But that is harder than it sounds, especially since the demon has other plans.

    Summary

    Basically, this is a collection plot points in TFTM that aren't important enough to make it into the main story.

    "But Petals, why?"

    Out-of-story answer? I'm facing a lot of writer's block and I feel this could be good for fighting that. In-story answer? Fleshing out relationships between timeskips/before the main story. I hate taking breaks from writing, so I decided to make extra content for my blorbos

    If you don't know what TFTM is and this is how you find out (first of all, I am SO SORRY), Tales From the Multiverse (TFTM) is the story of an 18-year-old faoladh called "Delilah" who finds herself exiled to Underfell. This is due to her mere existence as a monster being a crime. In spite of her status as an outsider and an anomaly, she lives on with the goal to return to her home. The question is, can she survive the underground long enough to even achieve it?

    Summary

    Flex has been apathetic at best since the human fell into his underground. He doesn't care about anything, he doesn't dance anymore, and he definitely doesn't stare after pretty girls who own the dance floor.

    Except... Maybe he does stare at this one. Just a little.

    Summary

    (I'm doing a 30 day NSFW art/writing challenge to improve my nsfw works in both regards, and all of it for LJxSans because my hyper fixation is them for some unholy reason

    Day 7: Rimming/Anal

    WARNINGS OF RAPE)

    A reset happens, as Sans expected. He figures Laughing Jack doesn't remember him anymore, so he goes to fuck some random bunny monster he's had a few flings with before.

    Things go wrong pretty quickly.
