NinjaShot

Proving once again that the Japanese are way ahead of the game as far as certain perversions are concerned, NinjaShot offers insider tips on "Peeping, Voyeur, Upskirt shot, X-ray, Hentai, Exhibitionist, Flashing, Maniac video, Way of peeping, latest Camera technorogy and Ninja", brought to you by the genius who unleashed the notorious Helicopter Fuck upon the world and illustrated with plenty of pictures to show the various techniques in action. Unfortunately, the site doesn't seem to have been updated since last fall (though there's still sporadic activity in the message board area)—we hope it doesn't have anything to do with that police activity they were worried about?
