Use this pump to enhance blood circulation to your most sensitive areas. Adjust the cylinder to ensure a tight seal around your vaginal region. A high pressure is necessary for an effective seal. We suggest using a good water-based lubricant to achieve the required seal for successful pumping. Its easy to operate; place the cylinder over your chosen erogenous zone and squeeze the pump to draw blood into the area. You will experience suction as your clitoris temporarily enlarges and becomes more sensitive. To release the pressure in the cylinder, simply press the release valve on the bulb. The industrial-grade acrylic cylinder can also be detached from the pump using the clip system, leaving your clitoris suctioned inside. The kit includes 1 pussy cup, 1 hose, and 1 hand pump.
