Have the throbbing, steely hard-on you desire with Pumpworx Silicone Power Pump, the penis pump that delivers bigger, thicker, longer-lasting erections. The medical-style squeeze ball creates a vacuum effect that draws blood to the penis and increases sensitivity. Watch your cock grow through the clear tube, and use the quick-release valve to relieve pressure. When you’re ready, slip out of the pump and enjoy prolonged, rigorous fun! Easy to clean with soap and water, and comes with an enhancement ring for extended pleasure. (Please see our tips on How to Pump Your Cock and/or How to Pump Your Clit to enjoy your purchase safely.)
