The Original Vacuum Cup's hourglass shape provides a sublime tightness. This is achieved by combining the curve in the mid section and a special one way air valve on the silicon sleeve which creates a vacuum effect. The air hole at the top has a removable seal, allowing you to fully control the tightness level.

These advanced features, combined with an arousing "slurping" sound, and vibration, give you the feeling that you're enjoying a real deep throat experience. The cup itself has a soft, gentler grip for a maximum relaxing experience.
