Glass is the super-sexy material for sex toys and we love it! It is smooth, so there is no friction, it gives firm stimulation - which is ultra hygienic so it wont harbour bacteria. We love the weightiness of this dong, it feels wonderful in the hand, but even better when all those blue dots are rubbing firmly against your insides! Join the thousands of orgasmically happy men and women who enjoy an orgasm with the Clear waters - it's a whole new dimension to your pleasure! You can enjoy a cool one or a warm one. To cool it down place in the fridge for a short time or place in warm water for a short time to warm up the glass. Playhouse E-glass.
