Has your micro gotten a little...macro? Well have no fear! We made a separate collection for your longer fics based on the microcest prompts!!

Microcest is a weekly multifandom microfic prompt event for incest pairings that posts prompts to Tumblr and BlueSky every Wednesday. This collection is for works that are too long to be considered a microfic.

Macrocest is on Tumblr, BlueSky, and Dreamwidth.

Q: When will the prompts be posted?
A: Prompts will be posted weekly on Wednesdays around 10am EST/New York timezone.

Q: Where are prompts listed?
A: You can find our past prompts on our Tumblr under the tag #microcest prompt or on our BlueSky Microcest Prompt Feed.

Q: The day for the prompt has already passed. Can I still write a fic?
A: YES! You can still submit a work for any prompt that has passed.

Q: Will you reblog my post?
A: Yes, we will reblog every macrofic that tags our Tumblr/BlueSky account. Give us 72 hours to have it reblogged before reaching out to us about it. If we still have not reposted it in that time, then please feel free to DM or send us an ask about it.

Q: How should I incorporate the prompt into my work?
A: Feel free to use the exact word/phrase in your work, or just use the prompt as a general idea. (Example: if the prompt is ‘not in the swimming pool!’ then you can use that as a quote from one of the characters, or simply write about a scene where something ensues that maybe shouldn’t be done in a swimming pool.)

Q: What is the word count requirement? What's the difference between a microfic and a "macrofic"?
A: Microfics are generally anywhere between 50 and 500 words, however we understand they can be a bit longer than that. We recommend that around 1k words you switch from our Microcest Collection to our Macrocest Collection. (We are not going to be strict with this.)

Q: Can we join a prompt from Microcest/Macrocest with other events?
A: Yes! As long as it follows the rules of both/all of the events!

Q: Is faux-cest allowed? As in people not blood related partaking in roleplay?
A: Yes! Faux-cest, pseudo-incest, step-siblings, incest play, implied incest, etc. are allowed.

Q: Can I use a prompt for a non-incest pairing?
A: You can use a prompt for a non-incest pairing, just add it to our Oops Not Incest instead!

Q: I have an idea for a prompt, can I submit it to you?
A: Yes! Send your prompt here!

Q: I have another question that wasn’t answered here. Is there somewhere else I can ask?
A: Any other questions can be asked by sending us an ask on Tumblr or emailing us at [email protected]

1. All works need to include incest, but every fandom is welcome!
2. Relationships can include more than just the incest pairing, but the incest pairing must feature.
3. NSFW, Dead Dove and dark content is welcome, but please tag them accordingly.
4. If posting your microfic on Tumblr, please tag @macrocest and include:

- the name of the prompt
- your word count
- a note of nsfw content or triggers (somnophilia, underage, etc.)

This might look like:
