On the set of an adult video, of course there is a sexy actress, but in addition to that, there are always female staff members such as make-up, AD, manager, etc., but they are not filming all day long without any breaks, and there is always a waiting list for their turn. - If there is a staff member, most of the time they will wait and take a break in the waiting room or another room that is not in use when the cameras are rolling. - However, as you would expect from an AV production site, used underwear and sex toys are casually placed there, and some of the horny girls secretly masturbate to kill time. - In order to verify this, I left my camera behind in the clutter of my luggage, and while I was alone in a closed room, the camera captured every detail of the obscene acts of the girls indulging in masturbation! - !
