Directed by Mike John Released 12/9/1999 VHS 7/2001 DVD Cast: Anastasia (aka Anastasia Blue), Daniella (aka Daniella Rush), Sharon, Laura, Cativa, Cherry, Cricket, Lexington Steele, Mr. Marcus, Sean Michaels, Jake Steed This series was begun by Sean Michaels, who can be a very good actor and director. But by around 1996 or so, he seemed to get bored with the porno scene, in part because he has probably done it all. The quality of his work seemed to go down, and Mike John was added to this series as co-director to make the results better. John was a nobody before getting hired on by Anabolic and Diabolic, but he quickly proved his abilities with movies like this one. I believe Sean Michaels still had a part in the creative aspects of Up Your Ass 12, but Up Your Ass 13 is purely a Mike John creation. Since he wasn't the much-lauded director he is now, he had to make do with an inferior collection of female talent.
