    Summary

    It's been a year since the barrier broke and you are finally able to move out of your shitty apartment. After weeks of searching, you find a three bedroom house in need of a roommate. After doing some research and seeing the pictures, you immediately fell in love with the place. Everything about it was perfect. Well, except the monsters who own the place. Out of all the monsters in the Underground, why did it have to be the skeleton brothers?

    You weigh the pros and cons. On one hand, you can move out of that god awful, roach infested apartment. On the other hand, you have to live with the one person who can destroy you. The answer is so simple. But your heart isn't. Also, cockroaches should be burning in hell.

    Summary

    A skeleton and a human meet in mental hospital...

    What sounds like the start of a bad joke is Jane's reality. Which in all honesty isn't all that funny.
    Despite not really believing that she belongs in a psychiatric hospital, she tries her best to blend in and keep to herself, so she can leave as soon as possible.

    If only there wasn't a certain skeleton making it way too hard to stay away.

    A skeleton and a human meet in a mental hospital - and that isn't even nearly as terrifying as it you would think when you feel like you don't belong anywhere.

    Summary

    Sans was tired. He’s tried everything to stop his timeline from resetting. There where a few times he almost succeeded, when it had been Frisk instead of Chara who had faced him in the Halls of Judgement. But Chara always got her way in the end. There was only so many times he could witness his friends and family turn to dust. Sans was losing the will to fight. And he was certain that as soon as he gave up, Chara would erase this timeline entirely.

    So he faces down Chara, because he’s the only one who can. She’s on another genocide run, and he’s waiting patiently in the halls of judgement. Chara comes to him, he begs her to stop, they do battle, and he dies again.

    Chara resets for the final time. One more genocide before she erases the timeline for good. But this time, it isn’t Frisk who falls into the Underground. It’s a human no one’s ever seen before. And she just might be the key to breaking Chara’s hold over the Underground.

    Summary

    Between two part-time jobs and coursework, you don’t have time to look for a serious vanilla relationship - much less something more suited to your tastes. Turns out a certain Mutt didn’t get the memo.

    Shameless reader-insert fic, where a misunderstanding in the S&M club where you work as a bartender leads to sexy, kinky shenanigans with everyone's favourite Swapfell brothers (and a few more monsters on the way~).

    Slow-build: this was meant to be a PWP, but… I think it may develop a plot. SwapFell Papyrus (Mutt), SwapFell Sans. This is what happens when I can’t find enough stories featuring Mutt, apparently. I’m... sorry? #SorryNotSorry

    Summary

    It has been five years since monsters have emerged from Mount Ebott. Humans and monsters are coexisting peacefully for the most part, but the crime level has been getting higher by the day. Helen is just trying to keep herself and her brother afloat. In the 1930s, it's hard enough for a single woman to get by without depending on...unsavoury means. It doesn't help that her past holds secrets that destroy her fragile family in a heartbeat.
    Skeleton brothers Papyrus, Sans and Gaster have been leading dangerous enough lives on the surface. But when Grillby and a young human boy suddenly come into their home with an extremely injured lady, they find themselves pitted against a dangerous individual who wants nothing more than to keep humans and monsters separated, indefinitely.
    These four shall find their lives intertwined deeply. And if they aren't careful, monsters may find themselves a thing of the past...along with Helen.
