What is a Nipple Pump?
A nipple pump is a sex toy that applies suction to the nipple to increase blood flow and enhance sensation. Nipple pumps are generally used before or during sex to enhance sensitivity and sensation. Other times they are used by people regularly to enlarge their nipples over time.
Nipple pumps are made much like a penis pump, but instead of a cylinder-shaped piece they have a bulb or cone shaped piece to go over the nipples. They may be pumped manually, or include a mechanical pump for effortless pumping!
