Fetish Fantasy Series Deluxe Vibrating Nipple Pleasure Cups Black. Make your nipples perk with pleasure with the incredible Fetish Fantasy Deluxe 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 them most! <br /><br />For best results, turn the micro vibrator on, place the cup on your breast directly over your nipple, connect the flexible, non-kink air hose to the cupping device, squeeze the EZ Grip trigger handle until you reach your desired suction level, and remove the hose. Once you remove the hose, the pleasure cup will maintain its powerful suction until you pull the release pin on top of the cup. You will enjoy direct vibrations to your most sensitive erogenous zone while your partner enjoys your new puffy look! <br /><br />With as few as 2 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.
