That black thing in front is taken from a dog shock collar and can be activated with a remote control at a very long distance. It also has 10 power settings. I have two of these and believe me they work great. The ladies that have worn then hate them but they are sure well behaved when they have it tucked between their pussy lips. I have ever gotten over seven before they were a blubbing mess, screaming and begging.
!!!! Now, if there was a wireless remote bullet vibe attached in just the right spot, this could be so perfect.
