Joseph is more than capable of getting into Paula's head over the phone—she knew he could take complete control if they ever met.
Paula is a whole different woman over the phone—confident, in control, even dominant. Except when it came to Joseph. He was in a class by himself and he knew it. Not only could Joseph control her actions by voice alone, every pleasurable sensation that flowed through her was his to demand.
