I start out, back to the camera, pretty close, with pants and a shirt that doesn’t quite cover my midriff. I bend over or squat down and just a little bit, about an inch, of my buttcrack is showing. Slowly, over the course of a few minutes, more and more of my crack is exposed until about half of my ass is showing. At that point, I just pull my pants down to the bottom of my butt cheeks and bend over and squat down so you can see my ass cheeks open and close as I move around, oblivious to the fact that I'm being watched.
