Bound jock Brock Avery is strung up in the middle of the room with his mouth tape-gagged shut. He struggles to get free, but his hands are securely tied to the ceiling and won't let him. He struggles to exhaustion and finally collapses to his knees. He comes to and finds himself retied on the floor with a huge boner sticking out from his jock. The harder he struggles, the harder he gets. Finally he can't take it any longer and his cock erupts without ever being touched!
