Quinn's Russian Master

Lovely young Quinn is working as a restaurant server when a rough looking Russian customer winds up at her table. She's had lots of middle-aged customers flirt with her before, but never like this one. He leaves her a thousand dollar tip, which astonishes her. And then he shows up at her apartment in a limousine to offer her an 'indecent proposal'. He'll hire her as his personal assistant as he travels the world, at a monthly salary greater than what she makes in a year.
He doesn't have to tell her what the catch is. It's understood she would be sleeping with him during his travels. He invites her for dinner and, agonizing over the decision, she agrees. She's never slept with a guy twice her age, but he looks sexy in a macho sort of way. And the prospect of traveling to Paris and other places she'd never be able to go on her own was too good to turn down. In short order she's astonished at his prowess in bed and on her way to Paris in his private jet.
Along the way she learns that his tastes are kind of kinky, and before long she's being overwhelmed with the dark fantasies he spins. She plunges into the role of a sexual submissive, taught by him, his many female assistants, and then his male friends as well. It's all shocking and intense for the previously unsophisticated and innocent girl. But the heat is so scalding and the benefits so great, she can't bring herself to say no!
