The Butt Boy is a vibrating butt plug with a difference. Its unique shape means you can slip in the 1.75 inch diameter Butt Boy and enjoy anal and perineum stimulation at the same time. Simply turn on the vibrating bullet, sit down and rock for hands free fun. The 8 inch total length Butt Boy is made from silicone so it is hypo-allergenic and feels great against the skin. It's fully waterproof for easy clean up. You can also remove the vibrating bullet for use on its own. Batteries included.
