Cupping Kits are based on the oriental method of using suction to pull impurities of the body through the surface of the skin. In fetish play cupping kits are superbly diverse! They can be used on many areas of the body, such as breast, nipples, penis, and ass. The cup suction leaves a temporary mark on the spot it was attached. Vacuum cups are easy to use, simply attach the cup to the hand pump, hold the cup over the desired area--or body part, pump, and let go! The cup will stay stuck by the skin being sucked into the cup!
