The WC's drab, tiled walls echo with the sound of a zipper descending, revealing a hard, eager cock. The man, lost in his own world, begins to stroke his length, his grip tight and rhythmic. The camera, hidden discreetly, captures every vein, every twitch, every drop of pre-cum that beads at the tip. The air is thick with the scent of sweat and sex, the sound of flesh against flesh punctuating the silence. It's a private dance in a very public place, a secret exhibition for the camera's unblinking eye.
