Vibrating panties were originally conceived and brought to market by California Exotic Novelties' President, Susan Colvin. The designs have changed over the years, as has the technology. There are basic models that hold a simple vibrating bullet that works manually, to hi-tech remote control units such as the Astrea mentioned above (a DR. Laura Berman Item) to the Remote Control 10-Function Little Black Panty. The remotes are fantastic for couples looking for some discreet fun while at home, or out in public. The anticipation of a surprise "buzz" when out will add some new thrills to any relationship!
