Very good! To me, the ideal video is either a video cam with ample storage secreted on a dresser or? I've had partners who didn't know I filmed until after. The other is a spontaneous, "Hey. Let's film ourselves for fun." Then preset cam on dresser. I use my Canon R-800, I'm sure some are better, but it's fun to review when girlfriends get together).
Fun video, I just question the premise. If it was that easy you'd see it happen more often. And what ninny is going to let a total stranger video you having sex?
