The tag came before the story did. Most people who write futanari roleplay chat arrived through drawn work, where futa has been a labelled category with its own conventions for decades, and turned up wanting the same thing in prose with somebody actually answering. That is what the roleplay room is for. Free, anonymous, nickname only.
The word, and the words that are not the word
Futanari is the term. Futa is the everyday short form and what almost everyone actually types. It is a genre label out of drawn and animated erotica, describing a fictional body plan, and it has been used that way consistently long enough that the conventions around it are stable and widely understood.
What it is not is a description of real people. Two other words get thrown at this material and neither belongs anywhere near it: both are slurs aimed at trans women, both get used by people who do not know or do not care about the difference, and neither is used here. Futanari is a fiction genre about invented anatomy. Trans women are women, not a category of erotica, and they have their own room at trans chat if what you are looking for is real people to talk to rather than a genre to write in. Keeping those two things separate is not politeness, it is just accuracy, and the writers in this room are generally good about it.
How the tags work
The genre inherited a tagging vocabulary from art sites, and it does real work in a chat room because it collapses a paragraph of explanation into three words.
- Futa on female. The most requested pairing by a distance. One futa character, one woman.
- Futa on futa. Both. A different scene entirely and a smaller, keener crowd.
- Futa on male. Less common in the room, heavily requested when it does appear, and overlaps with pegging in the real-world direction.
- Solo and self-focused. Description-led, one character, often the opener for someone testing whether they like writing the body before they commit to a scene.
Say which side you want to play as well as which pairing. Wanting to be the futa and wanting to be with one are not the same request, and the room fills up with people assuming the other person will guess.
Why it writes better than it draws
Art gets you the image and stops. Prose can do the parts art cannot: what it feels like from the inside, the awkwardness of clothing, the moment a partner realises, the difference in appetite and stamina that the genre takes as given. That is a genuinely rich seam and it is under-written, because most futa material never had to develop an interior life.
The writers who do it well treat the body as a fact about a person rather than as the entire personality. She has a job, a temper, a preference about who starts things. The anatomy raises the stakes of ordinary scenes rather than replacing them. A first-time scene where the other character has never been with a futa before is the single most reliably good setup in the room, because it gives both writers something to actually play.
What runs alongside it
Certain things travel with the genre and are worth naming in your pitch rather than hoping for. Size is the big one and it is the reason a lot of people are here, with the same mechanics as size kink proper: not the number but what the number makes difficult. Breeding scenes run hot for structural reasons and the breeding chat conventions carry over intact. Excess, volume, and the physical consequences of both are a standing request. Corruption arcs, where an ordinary character ends up transformed over a long scene, cross straight into corruption chat, and dominance framing is common enough that a lot of scenes are effectively femdom with a genre coat on.
None of that is compulsory. Soft, romantic, entirely domestic futa scenes get written here too, and the people who want those tend to have to say so, because the loud half of the genre is the other one.
House lines
Every character is an adult. Beyond that the rules are the same as everywhere else on the service, limits are named before the scene rather than discovered during it, and a quick out-of-character check mid-scene is normal.
One social note. Because the genre gets conflated with real people so routinely, the room is quicker than most to shut down anyone using the fiction as a way to be unpleasant about actual trans women. It is not a complicated line. Write the genre, do not use it as cover.
Getting a scene going
Front-load the pairing tag, the side you are playing, the setting, the register, and post length. "Playing the futa, futa on female, office setting, slow build, para posts" is a pitch someone answers in a minute. "Any futa fans" is not, because there is nothing in it to say yes to.
If the shorthand is unfamiliar, the roleplay glossary covers it and how to roleplay covers post length, pacing and the in-character and out-of-character split. Finding roleplay partners covers what makes a pitch land.

The room is open
Bring the tag and a character to hang it on. The second part is what gets you a good night.
