I read this hentai doujin off of aerisdies.com and I really liked the story, I thought it would be fun to try out in a group setting if any girls (and guys) might be interested. The girls would mostly be the waitresses in various costumes (maids, nurses, etc.) and the guys would mostly be the customers. Of course we can switch things up and have female customers or gay customers coming in for male waiters, whatever roles people feel most comfortable with.
Basically, the owner is a sleazy, lazy jerk who doesn't want to pay the girls very much, and they're all working for him either because they're desperate or they're being blackmailed. They all live in the upstairs apartment above the cafe, and work there part or full-time (might be best to be part-time if you're not too frequently online.)
The girls can do dances, striptease, whatever, doesn't necessarily have to be sex (especially for the cheapskate customers.) There can even be groups and double-teaming.

Well, anyone who's interested, please post and if possible, mention what sort of character you'd want to play. And tell your friends!
