At long last, Tenga enters the sex machine market with the Tenga Vacuum Controller - a suction adapter for converting your favourite Tenga cup into a powerful vacuum pump. By simply pressing the "release" button you can adjust the pressure of the vacuum. When these arrived at our office everyone was impressed by the strength of the suction and the quiet operation. As with most Tenga toys, they can be a little confusing if you are unfamiliar with the way they work, but we can assure you - nothing compares to the Tenga sensation and this new vacuum controller take their cups to the next level. Completely mind blowing masturbation!
