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've always dreamt 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'll 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. When you've reached your desired size, just push the quick-release valve to reduce the suction and relieve the pressure. 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.
