Pump Worx Glow In The Dark Pump. Turn off the lights, turn on the fun, and watch your cock grow as it glows! The Glow-in-the-Dark power Pump will give you the size and confidence you have always dreamed about without any harmful side effects. With each squeeze of the medical style pump ball, your pleasure rod will grow bigger, thicker, and swell with power. Once you penetrate the smooth, PVC opening, you will quickly discover throbbing, rock hard erections that feel great and last and last with no midway performance letdowns. The soft PVC sleeve forms a perfect air-tight seal with your skin, creating a strong vacuum inside the chamber that delivers maximum results.

To prolong ejaculation, slide the included enhancement ring over your shaft until it’s nice and snug. The tight squeeze will prolong cumming, help maintain your erection, and extend the fun.
