    Summary

    You've always had hidden feelings for the certain mysterious skeleton monster who likes to joke around and slack off most of the times. You didn't know how it happened, you just found yourself nervously sweating and heart thumping when he accidentally brushed his phalanges against your hand. Since then, the feeling grew more intense whenever his presence is around you. You've considered confessing your affection for him, but you're scared how he's going to react especially you've never heard of a human having an interspecies relationship with a monster before.

    And it doesn't help being half naked right now with only a towel draped around your trembling body, hidden inside San's closet while trying to figure out how to get out of here without him noticing you.

    Summary

    One day you woke up in a body that is not your own with no memories of what happened before. You somehow ended up in a bar and met a few weird looking things that call themselves monsters. The weird fire one takes you in and you met a lot on interesting people- or well skeletons and other fire beings? God you wished you had your memories and a body that isn't 15 or so inches long.

    At least this fire one lets you stick around.

    Summary

    You met him at a bar.

    To be fair, it was a very nice bar. You didn't usually go to those kinds of joints straight after work, but it had started raining, and you were not looking forward to getting soaked. Thankfully, you had noticed Grillby's open, and it was awfully convenient. It being in the 'monster' side of down didn't perturb you. Monsters were already involved in your life.

    Summary

    The joys of being the only mage in an Underground society full of humans that wanted his head cut off, put on a stake, and burned... they were truly limitless. Being constantly targeted for harassment and always getting picked on for fights, having to constantly be on edge and defending himself and his abusive younger brother from the outside world that wanted them dead.

    On top of everything, he fucking hated his job.

    What he hates more is breaking a promise.

    What he hates a lot less is a skeleton monster that enters his life suddenly and changes it just as fast.

    Summary

    The world is a big place, but the multiverse larger.

    You never guessed you'd be where you were now, you'd never believe anyone if they told you. Just imagine someone came up to you and said "Heya kiddo. Guess what? A black boned skeleton that you used to read about in fanfiction just destroyed your universe and now you're a failed experiment and a few centuries old!"
    yeah, it gets worse.
    After years of running and hiding you finally found a home, one shared with a particular pair of skeleton brothers that adored you with every ounce of their souls and you them. You were happy, flourishing in the (fairly) peaceful life selling your goods and befriending kind monsters and humans.

    And then those stupid skeletons had to mess with their machines!!

    Summary

    It was cold, so cold, too cold.
    You were draining, slowly, as an orange whose juice would be taken....
    the warm juice, the warm and red juice. Leaking, through a dam's rift.
    You felt like an empty Shell, empty of what it contained, empty, too empty.
    You couldn't see anymore, couldn't hear anymore, couldn't feel anymore.
    You were surrounded by emptiness. An emptiness that took everything, and nothing at once. Then, Came the light.
    and you were no longer, empty.

    Summary

    You never leave your house without your gloves.
    The auroras paint the sky above the mountain every night, yet snow never falls.
    And the Favored Child is anything but.


    You stumble into the Underground, only to find that it's under the influence of a time aberration worse than that of Mount Ebott itself - a particularly vicious time-loop, to be specific, and seeing as the Favored Child has been missing for a few days now, you can only guess how long it's been in the loop. Rather begrudgingly, you set out to fix the mistakes of the child. You've not been an apprentice for a long while, after all. If anyone is to take responsibility here, it's you, the adult mage.

    Summary

    A little spot for my shameless Sans x Reader oneshots and momentary inspirations to gather! Particularly, of the magical kind. Nagas, sirens, winged monstrosities, cursed creatures, fantastical beasts of all shapes and sizes... maybe even a normal skeleton once or twice, if you’re lucky! Canon is a speck in the rear-view mirror and we're all just here to have fun.

    So just sit back, relax... and enjoy the mess that is me being totally self indulgent.

    Summary

    Sans and Papyrus were your best friends until randomly they just cut off all contact with you. This went for everyone else in your life so it didn't really hurt that much when they did.

    The only question is why they didn't do it sooner.

    So after two years of loneliness, what was originally a drop off turned into a hospital trip, a broken leg, and your once best friends now homeless.

    What should be happening is them owing you a thanks for rescuing their so called, "Cousins" from a fire.

    Yet here you are offering them a place to stay, at your big ass mansion for the next eight months.

    So now you live with the people who abandoned you, along with their so called "family" who by the way don't really like you because you're a mage, but it's barely relevant to the plot so -

    What could possibly go wrong?

    Dying due to a car crash wasn't on your agenda,

    Even more so,

    Being told to survive 5 months in the body of another person wasn't on the agenda either.
