Well, a few years back Cosmopolitan [UK] had this cover catch headline: The Kinky Castle - where men are kept in dungeons. Wow! I remember seeing it and thinking: hey, i thought that was a mag with some classy propriety.
I regret not buying it and reading the article.But it could hardly have been an undercover job - no doubt the owners o that Dominatrix Fortress (or whatever) knew they would be appearing in the press.
