Make your nipples perk with pleasure with the incredible Fetish Fantasy Vibrating Pleasure Cups! Using techniques derived from ancient Chinese cupping sets, these one of a kind nipple stimulators allow you to apply amazing suction to your nipples and combine the sensation with thrilling vibrations! The plastic pleasure cups are lined with super soft silicone and feature powerful micro vibrators that deliver incredible vibrations where you want the most! With as few as 3 pumps on each breast, your nipples will swell with passion, leaving them erect, puffy, and super sensitive. Once the tingly vibrations kick in, you will enjoy hands free stimulation to your most sensitive areas. To release the suction, simply pull the pin on the top of each cup to relieve pressure.
