The Beginner's Vibrating 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, flexible PVC opening, you'll quickly discover throbbing, rock-hard erections that feel great and last and last with no midway performance letdowns! The clear vacuum tube allows you to watch your cock grow, and the quick-release valve relieves pressure with a push of the button. Choose a speed on the vibrating bullet and enjoy extra stimulation while you pump up your pleasure rod. Beware of imitations! Only this potent pump can deliver results that truly satisfy! 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. When you're done, simply detach the cylinder from the vacuum hose and restore it to like-new quality with Pump Worx Toy Cleaner and warm water. Requires 2 AA Batteries (Not Included)
