The Vibrating Sure Grip Pump will give you the size and confidence you've always dreamt about without any harmful side effects. With each squeeze of the EZ-Grip pump trigger, 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. Turn on the powerful vibrating mini bullet and enjoy extra stimulation while you pump up your pleasure rod, or remove the bullet and use it for extra stimulation elsewhere. 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.) Features and Functions: Remote Control, Multispeed, Vibrates.
