Or you could just do what I've been doing for years: run ads in your local free paper for girls to do modeling, get them over to your place and then see how many will get naked, masturbate and suck dick on video. You'd be amazed how many "normal" girls will do this for $200 or so. Something about pointing a camera at a girl brings out the "bad" in them. I've got a large video collection of girls I've done this with but I never asked for nor got releases. Since I never planned to release the videos, I didn't care about releases. But it is a fun hobby that anyone can do. Legal? I don't know but no one has complained yet.
