Experience 5 suction settings as your penis gets bigger and bulges with rock-hard sensitivity. This pump includes a long cylinder with grooves for maintaining your grip and measurements along the side to keep track of your gains. No bulbs or hoses necessary - the automatic pump will cause pressure to build within the cylinder, easily managed by the plus and minus buttons. A light up display shows your tolerance as blood flow increases, engorging your penis and making it hypersensitive to every touch, suck, and thrust. When you've had enough, a pressure release valve will quickly free you from the vacuum.

The silicone sleeve of the cylinder helps to create a tight seal, but can be removed. Do not use with silicone lubricants.
