    Summary

    You watched him unwrap his lunch, pouting.

    “C’mon, man. Not even a bite?” He started eating and you groaned dramatically. “I’m starving. I’m dying right in front of you. You’re killing me, Papyrus.”

    “good,” he muttered around a mouthful of food.

    “Wow, rude. I have no idea why we’re friends.” You sighed, eyeing the glittery burrito.

    “because you like to mooch off of me,” Papyrus snorted. He finished it off, cracking a grin when you whined in distress. “besides, y’know i only eat this because m’lord made it. he can always tell when i give it away. i’ll get ya something from a food truck later.”

    You nearly cried. “Thank you! I swear, I’ll pay you back when I’m a millionaire.”

    “so, never?”

    “I’ll try.”

    Papyrus shook his head with a grin, reaching out to pat your head. “guess that’s better than nothing.”

    You beamed, soaking up the affection. Papyrus always had your back.

    But… you were still so hungry. You worried that soon, food trucks wouldn’t be enough. Nothing would.

    Summary

    The wonderful, beautiful, and quite frankly magical Moontamble has given me her permission to post my little Not Your Doll interpretation of her story, House of Sans!

    Yes, those pairings are accurate. It's going to get wild.

    This is an alternate universe where red Reader from Not Your Doll has just been kicked out by her parents, unprepared for responsible adult life. Her aunt can't take her in, and her only saving grace is a weird ad in the paper for a live-in maid. Tired of homeless living on park benches, she jumps at the opportunity only to discover two problems: One, there is an unexpected learning curve when it comes to her first real job, and two, absolutely every single resident of the house has a crush on her. Just GREAT.

    I wrote this as a way to get around a persistent writer's block with NYD Core early on, and with over 16k words of draft, it kind of got away from me.

    ***** I can't promise any consistent updates on this thing, it'll just be whenever like Mobfell. *****

    Summary

    Error and Lust could never get along but of course not. They're total opposites; a haephiaphobic glitch and the whore. They're fights were getting on everyone's nerves so some punishment was in order or at least that was what the Sanses were going for. Instead it failed epically and a new out Come was the result. Akarun was born, the fusion between Error and Lust. The Sanses now rush to find a way to separate them but maybe being fused isn't so much of a bad thing. They can finally learn about eachother and maybe get along.

    Summary

    It's not that Y/N had a bad life, just one that wasn't very fun or fulfilling. When you meet Papyrus and Blue, everything changes. When you learn your twin sister, Edwina, met them, you fear you've lost their friendship as you had so many that Edwina wooed away. But, to your surprise, Papyrus and Blue were just the begining. Through a series of events not of your control, you find yourself even more intigrated into the lives of several skeletons. Some don't like you and some do, but that's life.

    And your life will never be the same.

    Summary

    Many, many skeletons from many different universes are all living in one city. They've all been freed by their various humans, and are learning to mingle with each other and the humans. Skeletons start to meet, form bonds, discover things. Drama, laughs, and sorrow is abound. The creator of all of these characters sits back and watches, and, occasionally, slips into the world to mingle. Can they all really come together and make this mess of life work? Or is everything doomed to fall apart?

    Heavily inspired by Kamari333's 'Ebott is a Multiverse' series.

    Summary

    “Just,” Red sighed, slight annoyance in his voice. “Just fucking save it. Alright? Don't even start.” Red got out, his hands clenching shut as he avoided eye contact. He looked so utterly defeated.

     

    “Red,” Dance breathed, his soul thumping loudly in his chest. “You're beautiful.”

     

    -Red comes home and is hurt. Dance, being the only one there, insists on helping Red but things don't go the way they plan.-

    Summary

    We know very little about Error's past. He couldn't have always been the Destroyer, right? Where did he come from? Was he always a glitchy mess, or was he forced into that by Fate? Will he be able to forge his own Destiny? If you want to know the answers, or at least my version, read on.

    This is a story of an AU nearly as old as Underswap and Underfell, that has been hidden from the rest of the Multiverse. This is the story of Error learning about who he was before he was the Destroyer. This is the story of Error making his own Destiny, after centuries of being trapped by Fate. This is the story of Error and Startale.

    Oh, and a dog of course. You can't have Undertale without dogs!

    Have some Error Oneshots to either warm your heart and make you smile or clench your SOUL and make you cry!
    Sub!Error x Anyone

    (AUs or characters doesn't belong to me unless I said so. Undertale belongs to the one and only Toby Fox, and it's AUs belongs to their wonderful creators out there. I only own the story and the plot. The characters' characteristics will change and be altered for the sake of each and every story.)

    Summary

    This morning had started out excitingly, with you hearing people in the only other apartment on your floor as you closed your door to go to work. The last tenant was long gone before you moved in 5 months ago, and for all this time you thought that maybe having neighbors might make you feel a little bit less lonely.

    But now you would give anything to be lonely again. Lonely, with no neighbors throwing orgies on their first night.

    Summary

    You've hit rock bottom, or perhaps hell's bottom. You are now surrounded by hordes of lustful monsters that crave to woo humans into their beds, for the chance to take their virginity is sought after, like a one of a kind rare gem.

    Though the creatures of the underground treat you with respect, like a royal princess, it doesn't stop them from trying to take advantage of you, nor being bribed or sweet talked into submission. The worst of them is a tall lanky skeleton who laughs oddly. He vows to have you one way or another, even if it kills him. He has to, if he wants to reach his life long dream. But he wants his cake and eat it too, for he soon after wants you to fall for him as well.

    What are you to do? Is there any chance of escape? What risk do you take? And how far are you from becoming a fallen human? Just what will become of you then?
