Vulva pumps create a vacuum around your vulva and increase blood flow to the area. They can be a fun and stimulation way to increase sensations. Place the cup over your vulva and use the squeeze ball to create a vacuum in the cup. Because of the increased blood flow, the aRea will swell and feel more sensitive. You can simply lift the vacuum again with the air release valve. Clean the cup well after use with toy cleaner or mild soap for hygienic use.
