Size Matters See Thru Nipple Boosters 2.5 Inch

Suction and increased blood flow to the nipples can increase sensitivity
and improve circulation. The Size Matters See-Tru Nipple Boosters
enlarge and stimulate using gentle suction. Simply place them over the
nipple and squeeze the bulb to create a mild yet effective vacuum. Once
you let go, these fun nipple toys will stay in place on their own. With
the see through chamber, you get to watch all the action as you play!
