To have a strong and stimulated vagina, these double balls are the ideal toy for you. Insert the balls into your vagina and feel the incredible stimulation they provide. Each Kegel ball contains a smaller weight inside, so with every movement of your body, the balls knock against each other, sending delightful spasms throughout your vaginal muscles. These spasms will not only stimulate your intimate area but also work as a workout, strengthening and toning your internal muscles for maximum pleasure.
