Sorry to post so soon, but this one is too good to miss. It's actually a compilation of women masturbating - but the fascinating thing is that it's mostly the same woman, in several different masturbation sessions. The orgasms are excellent, all of them with genuine squirting (as opposed to the often-seen fake squirting, which is really urine). If this one doesn't do it for you, I think there's no hope. Let me know how you like it, either on this thread or in PM.
