IN THIS SCENE DIANA WEAR AN ARMBINDER OVER HER OWN TURTLENECK SWEATER
From Chapter 30.
"...Diana was the janitor for the studio after all photo shoots. Many times after crawling into bed after cleaning the studio she would have very erotic dreams. Most of the time she was in tight bondage and strong gag and needed to clean the studio as such. With her arms bound behind her cleaning the studio became a much more difficult task. Any missed spots would result in severe punishment".
