I'm not exactly sure why, but I'd always just assumed that finding Japanese SM magazines from the Golden Age would be a difficult, if not impossible, undertaking. So I never bothered.
Then I found out that Zetsu had got his hands on several of these collector's items during his recent trip to Tokyo. He and Master "K" had been taken to some shops by Urato Hiroshi, the fellow who used to rig actresses for Nikkatsu bondage flicks.
Suddenly, I realized it was time for another SM Safari.
