The Two-O is just like the award winning, top selling Screaming O vibrating ring, but with an extra enhanced motor designed to double the pleasure for mutual enjoyment. The popular Screaming O ring has one vibrator to be worn on the top for her but the Two-O improves mutual pleasure by adding another vibrator for him. What really makes this ring amazing is the Screaming O's trademark pleasure knobs that are designed to transfer the vibrations through the length of the penis which are now powered by dual motors to really turn him into a human vibrator! Disposable Fun!
