Watch real-time growth with a clear vacuum tube on a cock trainer pump, letting you see every inch expand as you pull.

This 4-piece system uses a Sure-Grip pump trigger for controlled growth and includes 3 soft PVC sleeves that gradually increase in diameter—start small and work up to the largest for a custom fit.

Penetrate the smooth, flexible PVC opening and you'll feel throbbing, rock-hard erections that last, with a quick-release valve to relieve pressure at the push of a button.

The tube's visibility plus a tight seal on each sleeve creates a powerful vacuum that rapidly expands length and girth. When you're done, detach the cylinder from the vacuum hose and clean it with Pipedream Toy Cleaner and warm water.
