Become rock hard with the high-performance pump system. Achieve an impressive erection similar to the iconic drawings of Tom of Finland by sliding your penis into the silicone sleeve of the cylinder and, if necessary, enhancing the seal with some water-based lubricant. Attach the hose to the top of the cylinder with the locking mechanism and press the comfort handles to start the suction. Every push, once the constriction begins, will be noticeable on the pressure gauge as well as on your penis. Heavy-duty, including cylinder for erection enhancement.
