The Volution Egg isn’tlike any other male sex toy. The twisting and ribbed sensation it gives you adds a whole new dimension to male sex toys. Now not only will you feel sensation going up and down but the twisting design makes it so that you feel sensation running from left to right and around. But that's not all! The Volution Egg is also ribbed inside to increase the sensation even more as it stretches and fills while you use it.
