Well, you could have knocked me down with a rabbit!
Flicking through my free copy of "Health and Beauty" magazine today (that's free to Advantage card holders, £1 to everyone else) and I noticed a weeny article on Vielle "a discreet battery-free clitoral stimulator."
Blimey, they'll be selling Naughty Nurse outfits and blow-up dolls next. Just realised I can't do a link without the directions - will have to follow up with link!
