The Ultra Soft Double Vibrating Beads 15cm is fully waterproof for a range of play possibilities. This dual penetration penis ring brings fantasies of double penetration to life without the need for a third party. The elastic ring provides gentle pressure at the base of the penis, which can produce a stronger and longer-lasting erection, while the 10-function bullet stimulates with exciting vibrations. Wear the vibrator either above or below your penis and bend the shaft into a curve to fit your preferred position. Always use with a generous amount of water-based lubricant for maximum enjoyment.
