A very quiet, leak-proof, innovatively designed, fully automated masturbation penis pump for one-handed use. The pump has 3 suction functions, the set function can be locked. The intensity of the vibration increases the blood supply to the cavernous body. In addition to increasing erectile function, it can also be used to increase the size of the penis. It is easy to use, with a single button to control the addition or reduction of air. The sides are metric graduated and the wall is completely transparent. It works simultaneously to provide the true suction effect and the deep throat experience. Cleaning: before and after each use, the ring should be removed from the cylinder and both should be washed with lukewarm soapy water and a utensil cleaner. A water-based lubricant is recommended. The product is waterproof, but the head part must not be placed in water! The package also includes a penis ring.
