Add the sensation of suction to your fetish play with this Beginner's 6 Piece. Cupping Set. Based on ancient Chinese cupping therapy, these modern day plastic suction cups create a powerful vacuum that stimulates your hot spots and delivers amazing sensations. The suction action gently increases blood flow and excites your sensitive nerve endings, creating a one-of-a-kind feeling unlike anything you've experienced. The cups can be used virtually anywhere on your body - but they really feel great on the nipples, clit, buttocks, or any other erogenous zone! Each cup has its own built-in release that instantly relieves pressure when you pull the black pin. To use, lightly lubricate the skin first, then attach the flexible hose to the valve on the top of each cup. Pull the EZ-grip trigger and watch your partner's skin rise with suction. After you've reached your desired tension, remove the hose from the cup and the suction will remain constant until you pull the pin. The cupping set works great for BDSM medical play or for an all-over soothing kinky fetish massage. Once you remove the cup, the suction leaves a temporary red mark on the spot it was attached to. Be sure to pump cautiously, excessive suction can cause breaks in capillary blood vessels, resulting in a "hickey" type bruise on your skin.
