It rolled around just recently that my buddy, famous dirty scribe, kink class teacher M. Christian and I were invited, once again, to Sin in The City, in Las Vegas. Chris and I managed to teach at this convention three years ago, when it was held at the Riviera Hotel and Casino, a mere week before it was torn down. (This is the casino that stands in as the “Tangiers†in the movie Casino). Way back when, we had had a grand old time teaching our dirty writing class, a cupping class and one on alternate bondage. This year we came in to manage the writing class and alt. bondage again, with Chris also managing double duty as one of the judges of the conventions’ International PERSON of Leather Contest.
