Her daughters are kind of sluts, but fairly responsible ones.
The 16ish one has a girlfriend who's an even bigger slut, who also fucks her brother.
The preteen so far has only fucked the boy next door her age(started off as rape, he got used to it) and her best friend(see above), but goddammit she's trying her hardest.
Meanwhile Mama is a school teacher who fucks her top three students Dominatrix style. She's kind of fallen for one of them, and the other two are already a pair.
