A solo gay session turns into a intense CBT ball play. The muscular, hairy-chested man sits on the edge of the bed, legs spread wide. He takes a deep breath, then carefully places his heavy, low-hanging balls into the awaiting metal clamp. A sharp intake of breath as he tightens the screw, feeling the pressure build. He strokes his thick, hard cock, leaking pre-cum, as he turns his focus back to his aching balls. He removes the clamp, gasping at the sudden rush of blood, then repeats the process, this time adding a gentle tug, milking his balls until he can't hold back any longer, cum erupting from his cock in hot, sticky ropes.
