Put Henry the Hoover down and slip inside this strong vacuum masturbator cup instead. The Strong Cup from the Air Tech series offers a firm and effective suction with incredible results. Internal air chambers dynamically increase the strength of the vacuum suction, so you can upgrade from plain-sailing pulling to furious fapping. The Tenga Air Tech Strong Vacuum Cup Supertight features thick, raised ribs and a super-tight grip for intense, more-than-satisfying play sessions. Based on the Original Vacuum Cup masturbator, the Air Tech range is free from an internal sponge, making them hygienic, washable and suitable for multiple play sessions. Simply lube up, play, wash and play again and again!
