Slipping securely over a nipple, the Bulb's firm cylinder surrounds even the smallest sweet spot to provide an airtight seal. Once in position, squeeze the purple bulb to activate suction. Inner pressure will draw skin up through the cylinder, stimulating nerve endings and encouraging firming blood flow.
4 little O rings are included. To keep sensitivity and sexy perkiness going for longer, place one over the mouth of the cylinder pre-pumping and slipped off and over the nipple afterward.
