This is the best oral sex simulator we`ve ever found - it really is an amazing toy. Brand new from the makers of the original tongue sex toy, this has serious improvements all over. The tongue itself is made from super-soft silicone and it "laps" at three different speeds. The control unit is small and easy to operate and just in case you want some vibrations as well, the unit comes with a bullet vibrator that plugs right into the controller for dual action. Size: 5" (length) Material: Silicone Requires: 2 x AA batteries
