What could be better than a vibrator that can be used under water? Imagine the possibilities - hot tubs, jacuzzis, bathtubs! What could be better than a long, hot soak and a big orgasm to go with it! The only rule of playing with a waterproof toy is to use a silicone lubricant - these do not dissolve in water. (Remember: silicone based lubes MAY NOT be used with silicone toys, they will erode them!)
