Reddit reviews Pink Box: Inside Japan's Sex Clubs

On three occasions with two women. No, not sharing.

Definitely one of the more interesting things I've done. I've had a few offers to play with couples, I've had a 16yr old offer sex for payment, an offer to star in an AV movie, asked to buy used underwear for money, actually help sell old school uniforms for money (shirt, ribbon, skirt, socks for 100,000yen!), been to a happening bar. I'm a little interested in going to a ranko party, just to have been to a real orgy, but the only well known foreigner-friendly one quietly disappeared a few years ago, probably worth looking up.

I really like this book too: http://www.amazon.com/Pink-Box-Inside-Japans-Clubs/dp/0810992590
Amazing look at some of the creative and just weird stuff that is hidden away in Japan's massive sex industry.

Great book about the clubs here:

News flash sparky, this image existed long before Anonymous called for action. It's from a book called Pink Box. It's relevance to the cause at hand is purely coincidental, and its posting on Reddit isn't part of that action.

I think this is what you're looking for.
