50 Shades of Grey: Banker Edward Sonderling is Real Life Christian Grey

"He whipped, she snapped,” is how the New York Post titled its expose of Priority Investors LLC's Manhattan investment banker Edward Sonderling whose girlfriend Frankie Santiago “embraced a role as live-in fetish slave” playing out “bondage fantasies" similar to the ones student Anastasia Steel and Christian Grey play out in E.L. James' erotic novel – and upcoming film – Fifty Shades of Grey.

Santiago, also known in the bondage-domination S&M community as “Althea Lyn,” was arrested Monday and charged with stalking, criminal mischief and aggravated harassment after having a “knock-down, drag-out” fight with Sonderling at the East 57th Street apartment where they lived. Santiago (27) recently found out Sonderling (53) is training other “Anastasias” on the side.

Santiago and Sonderling — known as “King Eddo” on Manhattan’s BDSM circuit -- where regulars in the Fifty Shades-style local scene where King Eddo bragged about being a “whipping aficionado.” According to the Post, Santiago (Althea Lyn) -- who had been a live-in “fetish slave” for about three years -- was once whipped at a downtown fetish event by Sonderling who shouted to the audience, “She has had a lot of practice. I whip her every morning before breakfast.”
