If you enjoy nipple play, you'll love this nifty little device. A mini pump specially designed for nipple enhancement, this simple toy applies suction to a small area to help increase blood flow and sensitivity. Includes stretchy nipple rings. To use, apply a little water-based lube to your nipples and the rim of the pump, depress the bulb and place over your nipple. Now, s-l-o-w-l-y release the bulb and watch as your nipple gets sucked into the clear tube. This in itself feels amazing, but once removed your nipple will be left erect and super-sensitive for subsequent pleasure. Combine this pump with the included O-rings to maintain firmness and sensitivity.
