Willing in Vegas

Chloe and Zach have been dating for a while and the relationship has been great except that Zach isn't used to being in relationships. He isn't the faithful type. Thought Chloe is the eccentric type, and always keeps him interested, his wandering eye still wanders. Zach has an upcoming boys trip to Vegas and as everyone knows, what goes on in Vegas stays in Vegas. Chloe knows Zach is the cheating type, and she was well aware of that when they got together.
Unlike many women Chloe is able to separate love and sex, but to teach her boyfriend just how valuable she is, Chloe is orchestrating a sexual romp with the help of some call girls in Vegas. The catch is Zach will have no clue that the dominating woman controlling the other women is her. She'll let Zach off his leash to have fun, but when Chloe takes over will Zach know it's her or will he be too blinded by sex to catch on?
