Summary
Just some short stories. Most of them are based off actually real stories I've heard before, others, are just from my mind.
I'd say their pretty good. (but no promises)
They're about Undertale AU ships. You may request a ship or even story ideas.
Please read. Or don't. I don't care. -

Summary
Cross finds himself responsible for the death of his universe. After years in the white unending void, his tears summon Nightmare, who brings him back to the Castle.
It’s the aftermath of a more brutal XTale au, where Cross deals with PTSD and OCD, while trying to make a place for himself in the gang. It’s difficult, when you make mistakes left and right.

Summary
The end times are here. Nuclear weapons took out a good chunk of the American population and killed others through radiation or the nuclear winter it caused. But Cross is still alive. He was living with his mom down in Mexico when the bombs went off, and now needs to journey across the country to find his family. Along the way, he meets Killer and his son Crescent.
Feelings, sadness, horror, gore, and potentially romance ensue. Oh yes, also there are zombies.

Summary
Dust was on his couch after yet another long day at work when he saw a blinding flash of light in his garden. Getting up he slowly approached the bay window to take a look outside... and saw four strange skeletons dressed as a viking, a noble, a knight and a Roman yelling in foreign languages at each other.
He didn't know why he opened the window nor why he invited them inside, but he did, and by doing so he sealed the beginning of a very weird adventure with his four new roommates...
Dust - Modern Time, speaks English
Horror - Scandinavian Viking, speaks Old Norse
Killer - Ancient Roman, speaks Latin
Cross - Medieval Knight, speaks Old French
Nightmare - 17th cent French Noble, speaks Classical French(Cross-posting on Tumblr ! @/mikimakiboo
Basically a story about the boys coming from different time periods and time traveling together
Short chapters but it allows me not to burn-out too fast :')
Also, time being what it is, I should specify that I did NOT use AI for anything in this story, the languages all come from long researches to translate word by word in some cases, I did it all myself without the use of AI)

Summary
Killer piensa que cada una de las decisiones que ha tomado hasta ahora han sido las incorrectas, pero aún así acepta el trato con el guardián de Au's, quién tiene la teoría de que el asesino puede redimirse si está dispuesto a cambiar.
Le entrega viales con la esperanza de que sentir algo nuevo lo motive a superarse y le regala un diario para que escriba en él.La historia está narrada en base a lo que él escribe ahí con excepción de uno que otro capítulo extra desde la perspectiva de otros personajes...
Intento apegarme lo mejor que puedo al canon de cada personaje...sus personalidades, ideales e historia, pero obviamente, por mera ficción, hay cosas que salen de eso.

Summary
Exactly what it sounds like; Flufftober 2025 with UTMV, except there's a different ship (almost) every chapter. Every chapter is in a different universe--except when they aren't. I don't know what else to say. Expect OOC-ness and fluffiness.
Also, I apologize, half of these ships do include Nightmare. I have a favorite.
Now including a table of contents! And if you can't tell, this won't be finished by the end of October. We persist, however.

Summary
Коли на вулиці сонце припікає гірше за борги по навчанню, а єдине місце з працюючими кондиціонерами оповите університетськими плітками про неминучу погибель в ньому, залишається лише одне: забити та відпочивати в тиші і прохолоді, допоки твій спокій не порушить єдина людина, чиє сердце з першого знайомства належить тільки тобі.

Summary
This is sort of a college AU, it isn't based on the canonical multiverse nor relationships.
The characters may be extremely mischaracterized, I don't care honestly. This is just my life but with sans AUs bc I can't find another method to cope with it.I may or may not finish it, I'll probably upload when something big happens in my life or something, sorry for gramatical mistakes and not being constant in my work.
Anyway have fun reading :]- Language:

I meant to post this on October 14th, to post a very Gay and genders not being "black and white". Better only "late" by two days, that never.
Currently I'm posting porn on racists/bigots birthdays to spread fun Gay/Lesbian/Rainbow porn. OR until the "credit card censorship" is less of a problem.

Summary
Nightmare is already scolding him in his condescending yet apathetic voice. “Given your name, I thought you would restrain yourself to murder.”
Killer grins, hiking his shorts back over his pelvis. “Gimme some credit boss. I gotta get my sick kicks and my dick wet at some point.”

Summary
A story about Ink and Co. being space pirates and are living in the vastness of space.
Dream and Nightmare are immortal pirate captains, well known and feared among merchants and other sailors alike as Burning Sun and Kraken.
Ink, also immortal, is a member of Dream's crew and has been his closest friend for as long as he can remember.
It's a dangerous life they live with the guard hunting them down and trying to kill them.
So what happens when Dream and Nightmare get a call asking for help from the very guards that want them dead, offering a full pardon for their crimes if they do.
All they have to do is catch someone who is known as the 'Destroyer' and bring them in, so they can be dealt with permanently.
Problem is, no one knows who that is.Series

Summary
My hatred grows, my determination intensifies. The dust surrounding me is insignificant compared to my rage toward the human. "I regret nothing," I say before unleashing my fury.
But then, Chara's words haunt me.
"Feeling something new, huh? I want to try again."⚠
- "Semi-Canon"
- This is just a fanfic that will likely end as soon as I run out of ideas. If you don't like what you read, I'm inviting you to leave! Thanks for stopping by! -

Summary
Killer’s vision blurred, his mind hazy with pleasure. He needed to cum, needed it so bad it hurt. But Nightmare wasn’t letting him, not yet. He just kept him there, stretched and full, as if daring Killer to break.
"Come on, baby," Nightmare teased, "You can take it, can’t you?"

Summary
Error and Nightmare moved on from each other. Finding someone else to spend the rest of their natural life with, they never expected to ever see each other again with how big the multiverse was. That was all proven wrong when their children became friends and they figured out they were both divorced, not to mention single.
(I am shamelessly going to make them hate/love each other)
*Fic inspired by Song: I Could Never Fall in Love With You by Tub Ring
