I've been looking with keywords like sounding, insertion, event checked fetish in case there was something there, but I can't seem to find anything related. What would be a good place? 🤔
There isn't one afaik. Just a note that Lemmyverse (and LemmyNSFW) is very vanilla currently and fetish content (especially like this) tend to get downvoted by folks who don't know how to filter out or block specific types of NSFW content in their feeds.
Just try to name your new community (if you start one) smartly so that audiophiles don't get confused 😉
