Feel the powerful gripin your hand as you pump yourself to the max. Place the TPR ring around the open end of the plastic cylinder for an airtight seal. Attach hose to cylinder and pistol-grip hand pump. Apply a small amount of water-based lubricant before inserting an erect penis, then pull the hand grip to start the intense suction power. Monitor your progress with the pressure gauge and release air by pulling the trigger above the hand pump.
