Any good subreddits for posting transbian erotica?

I’ve been wanting to do some NSFW short stories as a means of getting me back into writing. Got a really cute idea for one about a smexy witch lady giving a nervous egg an instant girlification potion. Steamy hijinks ensue.

Only problem is, I don’t know what to do with it? r/sexstories doesn’t really seem like a community with the kind of audience I would want. And websites dedicated to horny stuff just generally seem pretty shady. I don’t want to put in a ton of effort only for nobody to see it though, so I don’t really know what to do. Any ideas?
