The theory behind pussy pumps is pretty simple, a vacuum draws blood into the labia and clit, enlarging and increasing sensitivity. Find out for yourself if extreme levels of pleasure really are possible with the pink Pussy Pump. The 4 inch long cup is ergonomically designed to fit around the pubic area and fit tight for maximum effect. A no-kink hose connects the cup to a small and manageable bulb, and when it's squeezed, a vacuum is created within the cup that is thought to draw blood to the area, in turn increasing your pleasure. There's a quick release valve on the bulb for your safety and comfort, and you can actually disconnect the hose at any time with no loss of suction. It's easy to use and easy to clean, try it out, you maybe pleasantly surprised by the results.
