With six cups in graduated sizes, you can experiment with powerful suction and increased sensitivity! Stemming from Chinese medicine, this unique method of relieving sore and aching muscles also makes for an erotic massage, intense BDSM play, or an exciting exploration of self pleasure. Simply place one or more cups directly onto the skin, creating a strong seal, and attach the hand held pump to the green and red tip of the cup. Pull the pump trigger to create suction, working towards your comfort level. Lubricate the skin first in order to slide the cups around for different sensations. The pump may be detached and the cups will still remain attached to the skin by the vacuum. Acu-Points centered at the top of the cups provide additional stimulation against the skin, should you choose to pump that far. When you are finished, the pressure released easily by pressing on the red tip.
