The Air cushion cup by Tenga is a masturbator that uses the power of air pressure and specially designed texturing to massage your penis. The jelly inner sleeve (which comes pre-lubricated) contains 24 air cushion chambers that create a uniquely tight clinging stimulation. This jelly sleeve resides in a discreet plastic tube (or cup) with a hole at one end; this allows the user to control the vacuum tightness of the sleeve. The air pressure caused by pumping in and out of the tube is converted into intense pleasurable sensation by a series of tightening and massaging nubs. This texturing grips the penis from all sides and creates an immense amount of stimulation to the head and shaft.
Per the manufacturer, this item can be disposed of after use. If additional use is desired, the internal materials can be removed and the sleeve rinsed before reassembling.
