This modern version of the Cupping Set features 10 plastic cups, and the suction is produced by a pump. Although traditionally used for medical purposes, they can also be used for sexual purposes. They produce interesting physical and sensual results when used on nipples or other sensitive areas.
In traditional Chinese medicine, suction cups are often applied to the surface of the body at certain points, sometimes in conjunction with acupuncture and/or acupressure. Traditional suction cups are made of glass, and are heated before being placed on the body. As the air inside a glass cup cools, it contracts. This contraction creates suction which practitioners believe has therapeutic effects. While the medicinal purposes of these cups may be a mystery to us, their sensual applications are not. When used on the nipples and other sensitive areas of the body, the physical sensations created can be quite stimulating.
