Whether you believe these things actually make your penis bigger or not, there is nothing more fun than sticking your dick inside a giant tube and pumping away till the cows come home, eh? It's fun, it looks insane, and it feels kinda good. Yet this pump goes one step further and features a state-of-the-art vibrating pouch so it acts as a penis pump and jerk-off tool at the same time. So no matter what, you're going to get something out of the Vibrating Big Man's Pump, be it a larger pecker or 30 seconds of pleasure and a spermy prize at the end.
