Slightest Touch - foreplay for ankles. Yes, ankles. : Shiny Shiny

At first glance you could be forgiven for thinking that this is one of those machines that makes you thin by sending electrical pulses through your body. It's not, though: it's much better than that (or so they say, anyway), so this is actually a naughty toy. You attach two electrodes to your ankles, and it sends titillating electrical impulses north, creating what the websites describes as "continuous, rhythmic and erotic sensations from beginning to end". It's $139.95.
