Girls might occasionally want some time alone. Two high-performance HD cameras, installed near the monitor and ventilation duct of a female-only DVD box set, secretly record their private moments. As they watch their favorite DVDs in the private room, their attention gradually shifts to their own bodies. They begin touching their clits with their fingers, slowly building arousal, until eventually inserting a large vibrator into their pussy, the wet sounds echoing throughout the room. All of it is captured on video, unfolding like a movie.
