The Rolling Tenga masturbator is perfectly compatible with the Vacuum Gyro Roller from Tenga to enjoy an intensely rotating handjob massage with a suction effect. It is simply inserted into the Vacuum Gyro Roller and pampers the penis fully automatically. Of course, the Rolling Tenga can also be used for a handjob without the Vacuum Gyro Roller. The Rolling Tenga is available in 3 different degrees of hardness of the inner structure: Regular (grey) for a gripping experience. Gentle (white) for a soft and smooth experience. Strong (black) for a very intense, dynamic experience. The disposable masturbator is ready for immediate use. After the soft insertion, the lubricant ring provides the penis with plenty of lubricant so that additional lubricant is not necessary. For the suction effect, remove the sticker from the vacuum opening at the end of the cup and close or open it with your finger (as desired).
