A three-hour streaming group sex tape aired recently in China by condom giant Durex seemed to leave viewers wanting more when the promised orgy stopped short of climax. The innovative condom and sex-toy marketer sprung its latest surprise to grab even more attention from consumers used to the company's humorous and risque pitches. This time around, 50 couples gabbed, flirted and smooched before heading for the sheets. Alas, what seemed poised for an epic romp turned into a tease when the screen disappeared in a cloud of white smoke.
