Gathered in a cramped, dimly lit classroom, a line of young, eager twinks await their lesson. The teacher, a dominant, older man, paces, his gaze flicking over their naked bodies. He orders them to masturbate, their hands gripping their hard cocks, pre-cum beading at the tips. As they stroke, they're told to piss, the stream arching out, splashing on the floor, and onto each other. The teacher joins in, his thick cock adding to the mess. The twinks, their bodies glistening with piss and sweat, continue to jerk off, their moans filling the room as they cum, their loads mixing with the urine and teacher's semen in a filthy, erotic display.
