I don't know anywhere dedicated to NSFW AI stories (I think I heard of the NovelAI community having a Discord for it or something), but you could try the AI-Generated Text tag on Ao3:

Granted the works in there aren't all necessarily going to be entirely or even mostly AI, since the tag is a bit broad. I have seen at least one account on Ao3 dedicated to posting AI stories though, and surprisingly there wasn't hate in their comments sections (or maybe there was but they were moderating/deleting it), just some people pointing out when the AI did silly things (like going back and forth on a character's pronouns).
