The California Exotics Black Jack Stroker highlights the best use of penis pumps -- masturbation. Inside the vacuum chamber a robotic masturbator slides up and down while you create perfect pressure using the quick release valve. The result is very similar to an awesome blow job without the risk of teeth. Once you've achieved your desired suction you can let the machine do all the work -- leaving your hands free and clean for Internet surfing or caressing your partner. Now this is a good use of technology! Sphere: Related Content
