In general I'm really looking for a "slutty" 18-25 or so year old girl teaching another girl about sex; convincing her to join in a threesome with a boyfirned/etc./ sorority hazing; or porn with newcomers where an industry veteran walks them through things. Light femdom and maybe forceful kissing, but i'm not really into clamps and tying girls to sybians and that stuff.
Nubilescasting and some other casting with female agents/etc. come close to this, but can't really find much of it that isn't heavier femdom stuff. THere seem to be a couple series of older couples or MILFS "teaching" sex to their stepsons or daughters, etc. but not a whole lot of this stuff. My favorite scenario would be sorority pledges, but there seems to be not as much sorority porn as one might hope or imagine.

Another bonus would be if the guy in the threesome was there mostly as a prop (moreso than in in usual porn) and was ocassionally critiqued or teased by the . Or if he's someone the slutty girl is helping score, that kind of thing. Like a guy gets "kidnapped" and used for a sorority ritual, etc.
