I took a break when we were filming a movie to have a cigarette on the rooftop of the building. But then when I was up there, I started thinking about the scene we had just shot - not with me in it - and I got really horny. It had been awhile since I had sex, so I started touching myself a little. I was having a moment! I guess everyone was waiting on me downstairs, and our camera man came up to get me...I kept telling him I needed a minute, until I just decided he could stay and watch as I masturbated. That seemed much more logical than having him run up and down the stairs until I finished to see if I was ready.
