Experience the unique sensation of a stretchy soft sleeve inside a vacuum pump that squeezes and pulls like the real thing, with a tight TPE chamber textured for extra pleasure. Choose from three speeds of vacuum suction, or opt for the special feature that sucks and releases alternately for an incredible fantasy-fulfilling sequence, all the while humming along with a 9-speed vibrating base. Use the silicone sleeve to turn your vacuum toy into a penis pump to build length and girth – and even keep track with measurements along the side. Height: 34.3 cmDepth: 9.4 cmWeight: 751 gram.
