In the dimly lit, cluttered study, the horny old professor indulges in a late-night solo session. His wrinkled, hairy hands grip his stiff, uncut cock, stroking it feverishly. The scent of aged sweat and musk fills the air as he grunts and moans, his body tensing as he unloads a thick, ropey stream of cum onto the dusty floor, fantasizing about the tight, young holes he'd love to fill.
