This is from the "White" series of Tengas that have a softer, gentler grip for a more relaxing experience. Fantastic stimulation made possible by the unique air-cushion mechanism. World’s first onanism cup (onacup) to adopt an air-cushion mechanism without relying on the elasticity of sponge or urethane materials. The ultimate, never-before-experienced clinging sensation has been achieved by allowing free changing of the air pressure in the 24 air-cushion chambers of this masturbation cup.
