This vibrating masturbator is designed in a shell form which allows it to mold itself around the penis. The sides are flexible which enables you to determine the tightness of the masturbator yourself. The interior is designed with a ribbed structure for extra stimulation. The masturbator is also waterproof and can be used under the shower. Start the vibrations easily by pressing the uppermost button briefly. Use the lower button to switch between settings. The masturbator can be charged via a USB cable and is easy to clean after use with warm water and toy cleaner.
