Soulbound Plants: Two Parts of One Soul Reunite. July 5 to July 21, 2025. Knives and Vash stand opposite each other on a bright teal surface lit with plant markings and encircled by a red thread of fate that ties itself firmly into the very words of the event.

“Soulbound Plants” has been designed to reflect the story of the plant twins, specifically as portrayed in Trigun Stampede, though elements from other versions of Trigun are also embraced. Each prompt will narrate a small aspect of the twins’ intertwined lives. All prompts are general, every creative is welcome to interpret the prompt however it inspires them, whether as SFW or NSFW or DDDNE.

We’re thrilled to announce “Soulbound Plants”!! A birthday event celebrating our favorite Plant twins! 🌱

🗓️ July 5–21
🎨 Artists, writers, creatives are all welcome!

Starting my stuff for Springcest 2025 with prompts set by @macrocest.bsky.social

I’m planning to do one fic per bingo board and will keep them all neat here in this thread.

#serpexwrites #macrocest #springcest2025

Officially, I’m starting my stories for the Macrocest Winter Bingo 2024 prompts by @macrocest.bsky.social

I am going for a blackout so for my own organization, I’ll be referring to the prompts as days and keeping them in this thread. ^^

chapter 1: #MacrocestBingo prompt "Our little secret"

A screenshot of a fanfic on ao3 Archive warning: Underage Relationship: Clive Rosfield/Joshua Rosfield Tags: 1510, Face-Fucking, Masturbation, Oral Sex, Clive has an oral fixation, Established Relationship, Short One Shot, Sibling Incest Summary: "Clive…are you sure this is what you want?" The question budded not from true doubt, but guilt. After all, when one asks, "What would you like for your birthday?" it's typical to expect something greedy of the recipient, centering their joy alone. And Joshua failed to see how straddling his brother's face without trousers was a gift for Clive…

💦Birthday Wishes🍰

A 1510 #Roscest fic for my #MacrocestBingo Winter card!

✨A short oneshot from Joshua's POV
✨Facefucking
✨Masturbation
✨We love Clive "Oral Fixation" Rosfield

Title: dripping red By: rivieras Summary: Rapid fire comments fill the screen, his eyes barely keeping up with the keyboard smashes and filthy words. Stoltz shivers. The thrill of people, strangers, watching him is intoxicating, enough to send his breath hitching and his heart racing in his throat. The camera blinks red.

Title: Smoking hot, only a street's width apart. Author: LegsFreaky Summary: When he turns back around, there's a look on Fuyumi's face like she's figured out the solution to ending world hunger, and Touya begins his mad dash out of the room in an effort to escape whatever she plans to suggest. "That's it! Why don't you two move in with each other?" Touya watches as Natsuo ogles their balcony neighbour for the nth time this month; he can't decide whether he wants to be her, or wants to fuck her too.

A graphic which says "Week 1 Progress 5 WIPs posted" with little icons of cameras, notebooks, laptops, and art supplies decorating the image. The bottom reads, "# Roscest WIP Fest"

Week 1 of #RoscestWIPFest has been bountiful and inspiring with 5 WIPs saved from the backlog!

And we see many more on the way with pledges and updates! 🔥 Keep it up! 🔥

An image which reads, "The WIPFest Begins Now!" Joshua and Clive are in chibi form, facing each other and preparing to attack each other playfully with cleaning supplies.

Onward, Roscest lovers! The #RoscestWIPFest has begun!
