Our publisher Mike ran into this device at the Adult Entertainment Expo in Las Vegas. It took him a good five minutes to work out what it was for. "This is fascinating," he thought to himself, "and it really needs to be written up for Gizmag. But certainly not by me." So I'm not sure whether to take it as a compliment or a measure of my character that he immediately sent the story my way ... anyway, in the interests of transparency, I wish to point out before we get started that the only chastity devices I have ever used have been my looks and my personality – and even those powerful tools haven't been very effective.
