    Summary

    Gonna try my hand at this for the first time! These will all be Sans/ Reader, but might play around with various AU's I don't normally mess with.

    Might also sneak some canon or not canon scenes in here from my fics if they fit hehehe.

    Also going to try to do some of these with Gender Neutral readers, which I am not very good at but gonna get some practice in! GN Reader will stand for Gender Neutral reader.

    Summary

    As you walked you failed to hear the screams of terror of a bus going over 100 miles per hour and the sounds of it starting to bust down- it speeds near the sidewalk—the people in it shriek. Their blood curling screams didn’t occur to you, your headphone quality being way too good. Your shoulders relaxed as you stretched your limbs; very much unaware of the danger and pain that would very much make your life way more miserable. You should move out the way. But- likewise, you are unaware. Of death flickering and time excited to cut your strings.

    The bus is almost out of energy- and has been stopped.

    Or so people thought.

    It began to tilt- right where you were very much slowly walking. Andddddddddd—

    It didn’t crush you to death.

    Summary

    Seeing a murder in an alleyway was the last thing Riley ever thought she’d see happening in her small town WestonVill. Having the murder disappear over night and the murders move in across from her was also something she’d never expect to happen. But here Riley Dottingham was, being pursued by two mentally unstable skeletons.

    If she could only figure out what they want from her.

    Summary

    You are on death's bed, there is no denying it at this point. Your good friend listened to you rave about an upcoming otome game you have been desperate to play since you've heard of it's creation. Only to sadden when your prognosis would keep you from seeing it in your lifetime. Well this good friend manages to get you a copy. So who would have thought that when you eventually passed on, you'd wake up as a healthy you? With goat ears, nubby horns, and a cute fluffy tail? Also a barrage of skeletons waiting on you hand and foot, calling you their queen... After playing many routes, there is one thing you are sure of... To make sure Black doesn't kill you like he does in the game... yet you don't seem to understand the stark contrast of yourself vs the queen as the skeletons do... and if you aren't careful? Black and the others will fall head over heels for you.

    Summary

    It has been a few days since they took you. You still don't know why, but you were more than happy that their apparent leader - “Nightmare” they call him - has ordered for them not to kill you. That doesn't mean that you were particularly safe either. When the one they refer to as “Dust” complained, Nightmare just told them: “As long as you don't kill her, I don't care what you do.”

    Why was he so adamant about keeping you alive though? Not that you were one to complain about that fact. It was just… these guys have proven themselves to be quite the violent bunch, rampaging through half the town where they then ultimately captured you while you were hiding out with some strangers.

    Summary

    You died.

    Plain and simple, one moment you were there, strapped to the table in that ever so dark laboratory. Then a loud cracking had occurred - the sound of your own soul giving up. It had been deafening, like ice breaking beneath your feet. That purple crystalline heart shattering like fragile glass, unable to persist any longer.

    The testing had been too much for you, not even you could persevere through it. Not after months—years.

    You…died?

    Then why were you here? More importantly where? What had Gaster done? And why did reality seem to glitch in and out with every painful thrum from where your soul should be? And who were these skeletons that felt oddly familiar to your soul.

    >> Persevere?

    Summary

    ‘Whaat?” He's being coy. Hmph. “What’s wrong, huh?”

    "You know what's wrong-"

    "Say it." Killer husks, and suddenly, Cross is very aware of how close he is right now. "Say it."

    “They’re a kid. You just said you wanted to fuck a kid.”

    “Kid.” He sighs dreamily, clicking his tongue. “But, like, not any kid. Our kid. Our special little human.”

    “That makes it worse.” He’s going to be sick.

    Summary

    After endless resets and what feels like an eternity spent waiting, Sans no longer remembers how long he’s been alone or how many times he’s painted the Underground in dust.

    The dust that never leaves his hands. The echoing voices that never stop.

    When another human finally falls into the Underground, Sans expects the game to continue. But this one is different. Against his better judgment, he hesitates.

    Mercy is a mistake he can’t afford.
    Yet...
