Designed for discreet internal use, the weighted balls deliver a thrilling erotic tingle with every jiggle. Each time you move your body, the balls stimulate the Kegel muscles for maximum toning and training. Wear the balls for toning up, and to enjoy spontaneous seductive sensations. The versatile exercise balls are perfect for the first time and experienced users. For extended arousal slip the pleasure balls inside the vagina during intimate solo play explorations, or as part of your couple’s foreplay fun.
