Vacuum pumping is gaining popularity both as a form of sexual stimulation, and as a way of increasing the size of your cock. The acrylic cylinder goes over your cock and forms a seal when you press it into your crotch. Attaching a hand pump (available separately) you can draw out the air from the tube - which forces an erection by drawing blood into your penis. The sensation is incredibly horny, and you'll immediately have the biggest erection you've ever experienced! It is claimed that with prolonged use, it can actually increase the size of your cock. Start with a smaller cylinder - that is a little larger than your cock when erect, then work your way up to the bigger cylinders. The measurements are diameter (width) and length of the tubes in inches.

Each cylinder is made of the finest, medical-grade, industrial strength, clear acrylic. Each cylinder contains a state-of-the-art air valve which allows for quick and easy disconnection from the pump while maintaining pressure within the cylinder.
