The world-first air-cushion design of the Air Flow Cup allows air pressure to flow between 24 internal chambers for completely new feedback upon insertion. This cup utilizes air pressure that fills up each of the 24 cushion chambers in between the sleeve and the plastic outer cup, mimicking the missionary sexual position fantasy. Instead of using sponge or urethane material to fill up space, the air chambers naturally apply even pressure around the inner sleeve, creating a sensational stimulation to the head and shaft of your member - delivering your most intense orgasm ever! The four-fold tightening zones and combination of nubs to convert changes in air pressure squeeze the penis from all sides. The Air Flow Cup comes with an adjustable air hole for your desired tightness. For an even better Tenga CUP experience: remove the sticker placed on the Air Hole of the Tenga CUPs before use. Additionally, you can control the vacuum suction of the CUP if you cover the Air Hole with your finger. Product Features:
