Do you like nipple stimulation and do you want to increase the sensitivity of your nipples? Then this nipple pump is perfect for you! The nipple pump is very easy to use. Place the cups on your nipples and use the squeeze ball to pump. A vacuum is created in the cups and that has a sucking effect on your nipples. The blood supply to your nipples is increased, making them bigger and more sensitive. An air release valve is attached to the squeeze ball, so you can lift the vacuum with the press of a button. Clean the cups well after use with a toy cleaner or mild soap for hygienic use.
