The 7.5 inch long Extreme Enlargement Pump is one of the most different penis pumps available.

This penis sex pump has the standard tube, although it is larger than normal and it has the standard pump action rubber bulb. In addition it also has a pressure release valve, so if you end up pumping a little more than you should you can quickly release the pressure.

What makes this sex pump different are the nodules inside the cylinder which stimulate your penis as you work the pump. A free noduled cock ring is also included.
