I think it is a perfect idea.

I have a board with tons of RPGs' on it as well as sexual RPGs' and they have worked out quite well. You can work with any topic in the BDSM role and discover all limits with a char.

Take it to a mansion in a secluded area, throw in some sex, murder, drugs, rck n roll, and so much more. Perhaps a brothel, or simply a strip club.

I used a brothel and strip club, added a money hack and it really turned out far better than i imagined.

Especially with VB codes it is quite fun.

You could even add a scheme for that forum to give it life.

RPGs' are a great way to broaden your horizen on anything sexual. Setting up char Bios to let everyone know what kind of char you are playing, give them equipment like chains, cuffs, paddles, clamps, etc.
