Whip your sex muscles into top shape with dangerously sexy Dare Devils. These sensually weighted, gorgeously styled balls are meant to strengthen and tone up your pelvic floor muscles, which can lead to more awareness, sensitivity and control over sensation and pleasure during sexy activities. When they're inserted into the vagina, you'll need to flex these special muscles (the same ones you flex when doing kegels) to keep the balls in place, and to feel the subtle vibration that occurs with movement. Since they're worn completely internally, you'll be able to secretly work out anywhere and anytime, from in the car to in the office to on the street with no one being the wiser. The sturdy beads within the soft casing can be removed, so you can start slow, with just one weight in place, and work your way up to both if you like.
