    Summary

    After college, you and your friends set out to look for a new place to live, hopefully somewhere familiar, with familiar faces. That plan gets scrapped pretty quick when you stumble upon a lively Southern city and its diverse population of both humans and monsters.

    Oh, and you're feeling pretty at-home in this hole-in-the-wall bar there. As well as with the bartender. He's pretty hot.

    Summary

    This is a human AU. Humans are trapped Underground, Frisk, Chara and the other fallen are monsters. Sans and Gaster aren't related, and Chara and Asriel are still alive.

    Sans is a young adult who needs a job, and Gaster is the one to give him one. At first, Sans comes off as lazy, uncaring, and unreliable, but soon the scientist learns that there is more to him than meets the eye.

    Summary

    Sans is in trouble. There are going to be a lot of hypnotic or tentacle sex themes in this. This is going to also be a lot of rape. Also I do chapters on my own, but please suggest pairings! Any AU Sans x Original! Sans! I can do more than one chapter and theme for any pairing. My favorite is---

    Dust! Sans x Sans...

    Summary

    Leaving the Underground lifted a weight from all Monsters, but the surface isn't quite what they made it out to be. The Monsters find themselves launched into a convoluted, modern world. The legal system is nonsensical and selectively applied, the regulations make building seemingly impossible even for well-heeled humans, but they themselves have not a single coin of human currency. Orcs are invading the country and the humans remain delusional about their intent and their actions and with the rule of their masters come weirdly one-sided customs. The traitorous centaurs remain alive and well, with a large reservation just to call their own. In their intent to resettle to the surface, the Monsters must defy apparent odds, dismantle threat after threat and work towards a peaceful and continued existence of Monsters and Humans.

    Current: A Knight's Coolest Dish
    The village is completed. The Monsters on the surface seek to settle down in their new homes and prepare for the incoming semester. And even on the way, some stumbling blocks await them.

    Summary

    It hasn’t been an easy 15 years since since the barrier atop Mt. Ebott broke and monsters were reintroduced to the surface world. The uneasy acceptance of monsterkind was hard won by many sacrifices though over the years tensions have settled into a general, though in some cases begrudging, acceptance.

    You are a grad student at the local university, eagerly pursuing a degree in Geophysics and Planetary Sciences in hopes of returning to the National Park Service. One step closer to the future you’ve had planned out since you were 17.

    Plans change, though… and along the way, you might undergo a metamorphosis too.
    *Please do not assume this is just a student/teacher kink fic, because it is not :)

    Summary

    All of the different Sans and Papyrus copies from the AU are here and they are all living together under one roof! The original versions of themselves! What is the catch or the reason? That is rather simple, their own universes were all destroyed, the kicker is that it was not errors fault, they don't know what happened, but it cannot be fixed. Now, several years later, they are all coping with the losses of their other friends while making new ones.

    There seems to be someone who wants things to fall out of place though, and he is targeting the original Sans to get it done. Now all of the AU have to band together closer to get him back after he is taken! How is this going to end? They will need to go back to their own universes to look back and see what they were taught that was important to them when they had gotten to their newest home. After all, lessons taught by friends are one of the most valuable things that you can gain, lets just hope it is enough to get them out of this.

    Summary

    It's been a year.
    One year since Frisk freed all the monsters from MT. Ebbott and became Heir and Ambassador to all monsters.
    In that time, they have made life for the monsters wonderful; They now had lands to farm, all the space they could want, and as much sunlight as they could handle.
    Life is good.
    Frisk now lives with her family, usually spending the weeks alternating between Toriel and Asgore, and spending the weekends with the rest.
    (Frisk particularly enjoys the weekends with Undyne and Alphys – They don't always make sure that she eats her vegetables, and they don't always remember that she has a bedtime.)

    Once a month, Frisk visits the underground.
    Her family believes it is just to visit the few monsters who stayed, and while that is part of the reason, her main intention is... different.

    Summary

    when the world went up in flames as monsters crawled out of the underground, humanity turned to its best chance at survival : hunters; an organization specializing with dusting the things that go bump in the dark. you're one of those hunters, tasked with a mission that went ass up faster than you could even blink, all because you were arrogant and impatient. now you're stuck with the consequences and you'll be damned if you go down without a fight.

    it's...better than it sounds. and it will pick up after the first chapter, which is a bit of a bumpy ride.

    Summary

    Sans disappeared one day with a note on his pillow, leaving you, a teacher at Dreem Elementary, and your son, Crisanto, by yourselves.

    It's been years since you've seen him, having only his quick letter to remember him by. But what happens when others try to help you? When they are willing to risk their lives to bring your husband back? To make your eyes smile as much as your mouth does?

    Please enjoy :)
    (Just putting this out there: although this is a Sans/Reader, it also focuses on your son. Like, a lot.)

    Summary

    Monsters have been freed from the underground, and honestly, you don't really think they should have. You wouldn't consider yourself 'racist', you just fear for your own safety when murderers wander the streets and move in next door.
    So spilling coffee all over a very large and intimidating skeleton monster was probably not your best move ever. But instead of gutting you, he offers to buy you another coffee. And, despite his... 'crude' language, he seems to be a nice guy. Maybe monsters aren't so bad after all?
    But why do the monsters who used to pay you no mind now cast you pitying looks and avoid you all together?
