Summary
This is a human Afterdeath werewolf au. The main ship is Afterdeath. But there is some implied Science x Geno, Errink, Cream, Kreme, ScienRed, Dustberry, Crossmare, Killermare Horror x Dust at some point. This is a slow burn, but it will eventually have smut.
Warnings: This first chapter has extreme violence and torture in the beginning, including some implied non-con. There will likely be death and other forms of violence throughout the story.
Fully covered in a black cloak. Everything around him seemed like darkness and death, just like the masked man. He could only see his mouth, which was unexpressive. He looks almost ancient. Frisk trembled slightly, bowing to him while Geno could only stare slightly before avoiding his eyes and walking past. The cloaked man stopped.
"You're looking better." The man's voice was deep and almost soothing, at least to him. They continued to walk, and Frisk glanced at him as they continued on their way. They walked in silence until the others were out of earshot.
"Who was that?" He asked, and she trembled slightly.
"H-he-" she cleared her throat, "he's the judge, and…he was the one who found you."

Summary
•``!english not my first language, srry, i use translate!
This is a translation of my work, which you can find on my account.When the sun outside burns worse than student debt, and the only place with working air conditioners is wrapped in university gossips that practically promise your inevitable doom, there’s only one thing left to do: forget everything and relax in the quiet and cool — at least until your peace is broken by the one person whose heart has belonged only to you since the very first meeting

Summary
Geno works the late-night shift at “Afterhours Brew”.. a cafe shop in town center that rarely gets much attention. At midnight, the shop always empty: Thats how Geno likes it. Soft lights, slow music, no annoying customers, and no rush. Just him and the warm smell of coffee. But every night, Reaper walks in. Same order, same seat, same tired look. And every night he shows up earlier and earlier, as if he’s running out of excuses not to. He claims he just loves the quiet. But the way he looks at Geno says something else entirely — Like Geno is the only thing keeping him awake. Reaper loves coffee. But He loves the hours when it’s just the two of them more . And Geno .. might be starting to stay awake for him too.

Summary
This is a vampire AU Afterdeath story!
He heard the footsteps get closer and closer until they stopped in front of him. Geno felt himself tense up.
"A skeleton?" The Duke's voice shocked him. He thought it would sound evil-sounding or deep, but it was silky sweet. Almost too sweet. It was perfect in every way.
"He's new, came here a week ago," Mr. Muffet stated.
"Hmm." He heard The Duke hum. Geno finally dared to look up. His eyelight nervously moved to the other's face. He didn't see much in the shadows but he could see his mouth. He narrowed in on that. The teeth looked normal. "I pick this one." The words made him pause in shock. Pick?

Summary
High school is rough. Even rougher when you have shit parents and mental illness. Even *even* rougher when you think you might be queer and your parents are homophobic. Yeah, Reaper is not having a good time - but luckily he's got an interesting new friend named Geno to help figure out just what the fuck this whole "teenage years" thing is about.
PS - for the best vibes, listen to the song in the chapter titles (names are in each chapter's notes); ill add a playlist link here when the fic is finished!! <333

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. -

“So if I were to get you drunk, you would be more honest? Gotcha.” by 12Hiraya12 for MoonMoom
Fandoms: Undertale (Video Game)

Summary
In where I got inspired while reading "Fill the Void" by MoonMoom when Ink mentioned about Geno's honesty if he was drunk.
It was Geno's 21st birthday! Yay! He's finally legal and able to drink, he says he doesn't want to but when did things ever go his way?
“Cheers!” They yelled and with that, Geno took his shot.
Note:
Spoilers to a bunch of things on Fill the void by MoonMoom, if you haven't read it and want to read it, don't read this. I recommend reading Moon's story, well, you should anyways. :P -
