Anal Insertable Smart Balls

These anal insertable balls are a blast, and offer more then ordinary ben wa balls. Small metal balls inside the silicon are equipped with quiet independent vibrators that are activated by movement. That means after these are inserted, you will enjoy the vibrations in your ass with every step, turn, or sudden motion. The vibrators are so quiet that if you dare, you can venture out into the world without anyone else knowing they are on but you. (Although some people may notice a smile on your face.)
