Stretch the soft silicone cock ring to slide over the head of your erection. Once in place at the base of your shaft it will enlarge your penis & help you keep your erection for a longer period of time. The edge of the ring is studded with nodes that aid in clitoral stimulation. For the best part just turn on the vibrating bunny ears & your partner will go wild. While her clit is being teased by the bunny; your entire erection has become a pulsating vibrator. You both will be in bliss.
