The Pleasuribe Pump helps to increase performance. Use it with a water-based lubricant to help create an airtight seal. Insert your penis, then press the hand ball to create a vacuum. As the air pressure increases, blood is drawn into your penis, which slowly increases the penis size. A quick-release button offers instant balance at any time. Transform your penis pumping session into sexy solo play with the addition of the vibrating bullet which offers a low to high speed to enhance your session through tingling vibrations.
