If you are dreaming of a larger penis, this penis enlarging penis pump is the answer. The Lust Buster Vacuum Pump is an easy to use penis enlarging device. It has a strong and durable plastic cylindrical housing, which measures 7.5”. To use, simply slip your penis into the plastic cylinder, then squeeze the advanced pump action rubber bulb to activate the suction and create a vacuum around the penis. The suction causes the blood to rush to the penis, encouraging tissue and muscle growth and, over time, resulting in a larger penis. For best results, daily use is recommended. Along with the penis pump cylinder there is a multi-speed mini vibrator for pleasurable stimulating sensations to the penis too. For additional information, there is a measuring scale along the side of the penis pump. The opening of the pump has a rubber sleeve to ensure an air tight fit at all times. There is also a quick release pressure valve for reassurance and safety. The Lust Buster Vacuum Penis Pump requires 2 x AA batteries to power the mini vibrator (not included).
