The soft and smooth texture of the Futurotic material provides a very natural feel for these duotone weighted pleasure balls. Each pleasure ball has a smaller, free moving ball inside. This creates weight as well as movement. Using your favorite water-based vaginal friendly lubricant, insert the balls vaginally leaving the nylon cord outside (like a tampon string). Play with them at home using a vibrator on the outside to feel exciting vibration on the inside. Or take them out for a spin as you go about your business. It will be your sexy little secret. As you walk and move, the weighted balls move inside you, creating stimulating arousal. Squeeze your little friends, working your vaginal muscles* as the tensions of the outside world melt away. Who said women don't have balls? Why not wear them to that next important meeting? Just make sure you take care of your special little jewels by cleaning them in warm water afer each use. Experiment and enjoy. *Also great for exercising the muscles for bladder control.
