I'm interested in this, as a flip-side to my usual nature in such a game idea.
I'd like to be the leader of the female gang of lesbians, the sexy bitch who plots, and thinks of new schemes, while enforcing the mean headmistress' rules.
I rarely play a dominant, but all I have to do is think of what my favourite style of lesbian villianess in a high school would do...
also based on very real girl-gangs in Japanese high schools (very wacky, but with interesting ideas).
Also, it woudn't be just for her fun, it's also profitable. The gang might terrorise half the girls in the school, but your one particular girl is deserving of special
It would in fact be the first time that I've ever played a dominant in a game online in years (God alone knows how long, because I can't recall)
