The Rockin Rabbit is a true lovers tool. Made of a soft rubber, the rabbit fits snug at the base of the penis, effectively helping maintain an erection. This alone will add extra-ordinary stimulation to both partners during love-making. Add one or both vibrating bullets to either end of the rabbit for clitoral, anal or testicular stimulation that is contolled by the multi-speed handsets. Or simply use the bullets on their own. Get ready to rock!!! (4AA)
