Not every workout is on a mat. These Fifty Shades of Grey Inner Goddess Silver Pleasure Balls fit neatly inside the vagina to help tighten the Kegel muscles, often stimulating the G-spot too. Add a bit of your favourite water-based lube, insert the first ball, then the second. Once you're familiar with the way they feel you can sit, stand and walk around, giving those Kegels a good routine. This intermediate set is perfect for those looking to move on from beginner level, weighing more and being smaller than a starter set. Get to grips with these and your vagina will thank you. To quote Anastasia Steele: "I flush from the constant movement of the silver balls...the sensation is exquisite." Enough said.
