A Lady Plays for Keeps (Cruel Games Book 3)

Leslie is determined to lose weight and exercise more. Diets and gym memberships aren't enough for her. As a sexual masochist, she designs more powerful incentives to motivate good behavior in the first two stories. And she doesn't hesitate to include her husband, Alex, in her new, healthy lifestyle. In the last of these three stories, she is convinced to apply her motivation techniques to a whole class of senior university students.
