Explore, experience and entice yourself with these Ben Wa balls. Insert these spheres into your vagina and squeeze your Kegel muscles to see how long you can hold them in. The silky smooth luxurious finish makes insertion totally comfortable, and the smaller girth makes these perfect for Ben Wa beginners. The stronger your Kegel muscles become, the greater force you can apply to a dildo or penis, increasing friction and the control you have over your orgasms. These balls are completely waterproof, so you can retain them in the tub or shower, and they are attached to a convenient retrieval string to make you feel comfortable that you won't "lose" them as you writhe in ecstasy!
