Screaming O BigO Vibrator Ring

The Big O Vibrator Ring is the only vibrator ring in the world that automatically switches between nine vibration patterns and can be used frequently as the replaceable batteries last +80 minutes. The ring at the bottom also acts as an erection ring, providing your male partner with a more potent erection. You can also enjoy it to the max in the bathtub, as the Big O is waterproof.
