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
A sweet little series set in a world where monsters had been captured from the beginning instead of shoved underground.
Eventually, as the years and generations pass, both humans and monsters slowly forget the monsters were ever free.
We follow the story of an aging little zoo hoping to expand and take in a few monster pups. And the stories of several monsters who find themselves being transferred to the place.

Summary
The Multiverse was frozen.
Deep, black ink dripped from the code of AUs.
Nothing new was being created, and nothing could be destroyed. Everything felt definitively fuzzier at the edges as the balance of energies refused to tip for anything...The entirety of the Multiverse was decaying, slowly but surely, and it was all because a certain Creator has gone missing...

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
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
The monster with beautiful blue irises that I sworn to never make cry again. I then turned around to see Horror, his one eyelight resembling a sort of fiery, red amber sunset you'd see in movies. I wish I could bask in their gaze forever, without them having to reciprocate for my heterochromiac eyelights; the self inflicted scars on my face engulfing any beauty you could possibly find in my eyes. It pains me to see them scared of me...
OR
dust horror and blue make some shitty french fries in the kitchen

Summary
“Stop messing around. We’re supposed to be keeping watch.” Cross huffed, turning to face XChara fully.
XChara glared at the snow when Cross said that. He reached down and scooped up some snow into his hand.
XChara ignored Cross’s attempts to get him to lock in. “Why do I even try…” Cross rolled his eye lights and turned back to face the crowd of people, but was hit by something cold and hard on the side of his skull.
“BAHAHHAHAHA!” XChara was rolling on the ground clutching his stomach from laughing as he watched the snow slide down Cross’s cheek.
-----
Cross and XChara find themselves stuck in the middle of an ongoing Multiverse war as they where sold off to Nightmares gang for his super secret evil plan----
first time writing fan fiction, kinda nervous
