Cestember 2026 begins next month!
Cestember is a month-long multifandom incest event with daily prompts hosted by @macrocest in September.
Basic Premise:
There is one prompt each day of September. You can choose to fill any number of the prompts or all of them.
Optional Weekly Theme:
For this year we have our daily prompts of course; but, we want to change things up a little bit each year to keep it interesting, so this year we have suggested relationship themes for each week.
For example, September 29th we have the suggested theme “unwitting incest” and the prompt “portals.” This could be used in a work where there is a portal glory hole where neither person knows who is on the other side. The suggested theme could be a large or small part of the work, it’s up to you.
(Remember these are suggestions, not requirements. Feel free to ignore them completely. They are merely to inspire you to branch out and try a new dynamic or possibly return to an old pairing.)
