Add a little fun to pelvic workouts with these luxurious colour-changing Kegel balls. Wrapped in silken black silicone, not only do these jiggle balls contain free-roaming weights for discreet arousal, they also change colour with the heat of your body. “I flush from the constant movement of the silver balls. They weigh down inside me, massaging me internally and make me needy, needy for sex. Oh, the sensation is exquisite.” – Anastasia Steele Tipping the scales at 90g and entirely encased in silken silicone, this set features two balls, which change colour from black to purple as your body heats up. As you move, the internal weights jiggle about. As your muscles clench around them they provide a light internal workout, which can improve vaginal tightness and aid orgasmic strength. The jiggle balls come with a Fifty Shades of Grey storage bag, making them an ideal erotic gift for fans of the books. Slather your jiggle balls generously with water-based lubricant before use, to ensure smooth insertion and a comfortable experience.
