Springcest 2026!

Springcest Fest is a shipcest (fictional incest) bingo event with a special challenge: to include all 3 squares of your bingo in one work. 

You can choose to make your bingo from any of three of the 3x3 cards below: 

The yellow time card designed by @windytalishar: Top Row: They grow up so fast | Deadline | Forever Middle Row: Making up for lost time | Back in the day | Monthiversary Bottom Row: Waiting | Never change | Too old

The blue horror card designed by @legsfreaky: Top Row: Kept prisoner | Flesh wound | "Help me!" Middle Row: It's all in your head | Haunted by their victims | Holy water Bottom Row: "Don't you trust me?" | Foaming at the mouth | Demon child

The green language of flowers card designed by @litcest: Top Row: Mimosa (Chastity) | Yellow Rose (Devotion) | Myrtle (Marriage) Middle Row: Poppy (Sleep) | Primrose (Youth) | Marigold (Jealousy) Bottom Row: Foxglove (Deception) | Wolfsbane (Poison) | Basil (Rivalry)

This event will run from April 20th to June 20th.

The goal is the same as any other bingo: to make a row, column, or diagonal by using each of the prompts, except this time you have to include them all in one work… or if you’re feeling particularly inspired: a full blackout card where you fill every prompt in one work. 

Works do not need to be posted specifically on AO3, they can be posted anywhere, but our AO3 event page has all our info and FAQs.

Good evening, Macrocest Fam!

I’m here to announce the second year of Macrocest Bingo: Macrocest Bingo Night Edition! Macrocest Bingo is an event centered around fictional incestuous relationships (shipcest). This edition will feature night-themed prompts but there will still be a variety of regular opt-in prompts included.

The bingo card request form will go live on November 15th, 2025 and will close Dec 15th, 2025.

Like last year, there will be a variety of opt-in categories including fluff, angst, smut, kink, and dead dove. Within those categories there will be more specific options (e.g. “kidfic” under fluff, “watersports” under kinky, “noncon” under dead dove) you can opt into.

We now have multiple bingo size options!

We will have 3x3, 4x4, and 5x5 options available.

Like last year you can request multiple cards, in different usernames and now in different sizes. For example, you could do a fluff-themed card under an Pinecest Tumblr username and a smut-themed card under a Gravescest AO3 username. Remember, though, that the more requests you make the longer it will take to make and send them to you.

There are two main rules:

1. No AI-generated works.

2. You can use two prompts from the same bingo card in one work, but they should be in two different chapters. (However, if you have two cards you may use two prompts from different cards in the same chapter. The two cards can both be from this year or one from 2024’s winter edition + this year’s.)

Otherwise, this event is meant to be very open to different kinds of incest and creative works.

Faux-cest/incest roleplay, pseudo-incest (godparents, raised like brothers, etc.), step-siblings, selfcest, implied incest, etc. are allowed. Any type of art is allowed: music, painting, origami, quilting, collaging, whatever brings you joy.

Original works are allowed. Dark content is allowed. Microfics are allowed. Combining with other events is allowed.

If you’re not much of a creative yourself then you could make a podfic or fic rec list of fics that fit the prompt.

Fills do not need to be posted on AO3 to “count” so you could do something like make a collage and post it on Tumblr. Actually, you don’t need to post at all! You could use the prompts in a private RP. The goal of Macrocest (& @microcest) is to get more shipcest into the world, even if it’s just for you.

There is no official due date, you can take however long you wish to complete your card(s). You can start posting as soon as you get your card.

I'm lusting (,,>﹏<,,)

I should draw more of these 2...

New fic out for @cestween​ 2025!!🎃 Prompt: Stalker

This was meant to be 1 chapter and done, but the plot has spiralled out of control (as usual), and is consuming my every thought. Will be working on this over the course of the next month or two, bar the occasional break to work on other deadlined projects.

Another Saturday night, another outing.

Months of meetings and dates, firsts and lasts, none of them his.

Natsuo sits in the corner booth. Touya stares through the café window.

His little brother’s date doesn’t show up, tears fall from stormy eyes.

Touya, he— he stands in the alleyway, and watches. His feet twitch.
