    Summary

    After living in Ebott for five years now, it certainly doesn't seem how you remembered it to be. With the release of monsters happening just after you moved back into Ebott, you've started to notice a lot of changes within the city. At this point, you don't know whether that's a good thing or not. One of the more notable and recent changes is the Monster Integration Program. A program you'll hopefully get accepted into. You can't help but feel as though this simple program holds a lot more importance to you than you'd like, and the simple fact of 'not knowing why' has you feeling anxious. Perhaps you'll meet someone important because of it...?

    Summary

    (Swapdream Multiverse with Diabetic Reader)
    Your multiverse was absolutely crazy. Obsessed with the way of thinking promoted by the godlike entity that calls himself Dream, positive emotions and thinking are prioritized and negativity ends up demonized as a result. But you don't really like that way of thinking. Not one to wallow in your own emotions, but your life sucks. Being a diabetic sucks. And you'd like to be able to feel every bit of negativity without being told off, thank you very much (Swan X Reader)

    Summary

    So I literally never see anything with a diabetic main character and especially not a diabetic /Reader fic. Skeletons are sexy so lets play around with ideas while I get a diabetic reader a harem of their own!
    (I have been diabetic over 20 years and I honestly can't tell if I should be annoyed or amused at my own title)

    Summary

    Listen don't expect much from me. I write this in my spare time and I'm always busy. This will probably be one of the shittiest things you will read on this site. I'm trying. If you want to insult it, be creative. I don't want "this is bad" or "this is cringe". First off your reading fanfiction by a freshman about a murderous deranged skeleton from an indie game that the internet gave a glowing dick and sexy tumblrman award to. Grow up. Second off you will either put positive things, constructive criticism, or you will be creative with your insults. Make me laugh bitches.

    If not, you can get rear ended by a car so hard that when you wake up out of a coma you end up masturbating to the Cars movies and grow a crush on Mater.

    Judging by that you can tell what kind of person I am and how this fic will go. Read at your own discretion.

    Summary

    “It's late, and it's raining,” you state, tugging his sleeve and halting his steps. The smell of smoke is strong, and it mixes with the earthy scent of the night. “Why are you trying to sneak away? You know you can stay for as long as you'd like.”

    He turns around, his figure darkened by the poor lighting of the patio, plus the lack of a moon.

    “solid suggestion, but you and i both know that's not a good idea anymore,” he replies, his voice sounding on the edge of exhaustion.

    Far used to his behaviour – one you've been a witness and victim of for the past few months – you roll your eyes and fetch a candle and a match from your pockets.

    “Oh, please. Don't be silly! You're always welcome here.”

    And as the flickering flame brings about clarity into the deep darkness of the garden, you quickly draw back a comment on him being dramatic.

    He's covered in dirt, and the injured body of a familiar face lays motionless on the floor.

    “just to let you know," he says, chuckling, ”i was only gonna drop this off." He gestures at a small, black box he retrieves from under his suit. "but that was your last chance to reject me, so now the fault's on you, if ya didn't want this.”

    Summary

    When your creations turn into reality, things were never meant to go well. Both you and your brother turn into the characters that both of you created and dread to be in. An alternate universe full of death and war.

    -----

    You were tired from this. Hell, both of you were. You were placed in the front lines while your brother created dangerous explosives. All of this just to survive, to live for another day. All memories are forgotten of who you once were before this painful life.

    Who knew a sudden mishap of a machine could be a savior for the both of you?

    Summary

    ”Hi there! Do you need any kind of help or are you just look-”

    You swallowed the rest of your sentence completely. Your mind trying to process the very thing which was in-front of you yet finding nothing which could explain either what or whom stood before you.

    ”Yo wazzup ma Dudette! Nice ta meet ya lil’ fella hehe” he waved one of his hands toward you before shifting both of his hands into a ’hey’ expression, fingers pointing toward you as his eyebrows arched up and down. ”I’m totes just checking out your Mad-Rad collection of music yo. But I waz thinkin’ - ya don’t have anythin’ totes more in the 90’s styles yo?”

    What on earth was standing before you?

    *A feel-good story about the values of friendship, laughter, the true meaning of living and possibly the meaning of having a Soul.*

    Summary

    You, a Witch, owned a potion shop in Ebott city where Monsters, Humans and supernatural beings lived in relative harmony. You had once had a chance encounter with two skeletons Monsters but to your surprise, both of them were supernatural beings! Quite rare for Monsters to be. Even though you had a hectic meeting with the skeleton brothers, the three of you became quick friends. The vampire skeleton Sans helped you around your shop when he could while his brother Papyrus, a werecat, came around to show off his partners…? Yeah you thought it was a weird way for him to bring you extra customers but highly appreciated!

    Everything changed when one adorable blue skeleton invited you to a yearly masquerade party and something unlocked inside two skeleton's minds when they saw you getting all nice and comfy with another Monster.

    They couldn't let their beloved witch be taken away now could they?

    Summary

    Alice is a disabled woman living alone, her sister-in-law gets her a suprise for her birthday.

    Best. Birthday. Ever.

    So, this work is still being written and has some tension between the mc and her new little noodle. That being said, I havnt decided if I'm going to leave things at mutual pinging or let things bloom, mostly cause I can't help but writing romance and smut. I've got about 6 chapters done and updates will NOT be on a schedule.

    Feel free to give suggestions, comments, or even offer tags I should add.

    Summary

    College is never easy, especially when you're majoring in Astronomy.

    And it's ten times as hard when you're shoved into another universe full of monsters, humans, and skeletons who are dying for your attention.

    You haven't been into Undertale AU's and the hot skeletons in them since you were an awkward teen...
    And now that you're an even more awkward adult, all it took was you being bored one night, and finally opening AO3 for the first time in years to get isekai'd into a world your younger self would've died to go to.

    What are you gonna do?
    And why are they all still so hot?!

    Summary

    It was the only job you could grab. Along with the apartment-life blues, and your college education still ahead of you, could your setting be any more typical?
    Maybe...if some of your regulars hadn't emerged from several feet underground a few years ago.
    But, darn it, you chose this particular store for a reason, and you were going to show these fascinating new faces in and out your door with a smile that (surprisingly) has nothing to do with the fact that you were getting paid for it.
    Good thing, too, because you might get to make some bone-ified new friends in the process.

    Inspired by several AO3 users (listed in the first chapter notes)

    Most importantly, where the hell are all these other skeletons coming from? Why are they all so cute???

    Read on to find out!
