Stroke4u, the master of self-pleasure, presents a solo show that's not for the faint-hearted. With his massive cock straining against his boxers, he starts his session by roughly fondling his heavy balls, already filled with pent-up desire. He lubes up his sack, massaging the sensitive skin, before bringing out the clamps. One by one, he attaches them, gritting his teeth against the intense pressure. With his balls now a deep shade of purple, he uses a vibrator to edge himself, denying his release until he can't take it any longer.
