Kink Vibrating Silicone Cock Cage 2 and Plug. The Caged 2 vibrating silicone cock cage from the Kink by Doc Johnson Collection takes sleeves and rings to another level with a long line design, built in ball strap, and two powerful vibrating bullets positioned for double the pleasure. One bullet sits at the top of the shaft, placed ideally for partner stimulation, and the other fits inside a tempting anal plug for backdoor fun. A strategic open design along the shaft of the smooth silicone sleeve keeps direct stimulation strong while the snug fit of the cage and ball strap tug and tease the wearer into a raging, rock-hard erection. Kink by Doc Johnson is an exciting collaboration with Kink
