One armed bandit pump – easy-to-master penis enhancing system

A powerful single-handed pump, the one-armed bandit courtesy of Doc Johnson™ is primed to set you on the path to vast riches of sexual pleasure. This wonderful piece is made of durable plastic and features a comfortable donut seal base that ensures a tight and secure fit that also accommodates to most sizes.

The pump works by way of an ergonomically designed finger piston that requires only two to three fingers to operate. As you pull the piston up, air gets sucked through the flexible coil hose, increasing the pressure within the cylinder. This powerful suction, coupled with the air-tight donut seal, brings blood flow into the penis, increasing the girth. Once the desired size has been achieved (or if you want to quit early), just push the quick release valve underneath the piston.

While some men say pumps increase size, others think they have no effect, and although pumps can extend length during use there remains no conclusive evidence to support either claim.
