Book excerpt: The remarkable true document that is The Mistress Contract opens with a piece of paper that was signed in 1981 by a woman and her wealthy lover. The contract establishes an exchange that she thinks fair: If he will provide an adequate and separate home for her and cover her expenses, she will provide him with “mistress services”: “All sexual acts as requested, with suspension of historical, emotional, psychological disclaimers.” For the duration of the agreement, she will become his sexual property. Then — on a small recorder that fit in her purse — this extraordinary and unconventional couple began to tape their conversations about their relationship, conversations that took place while travelling, over dinner at home and in restaurants, on the phone, even in bed. This book is based on those tapes. It is a candid record of what they had to say to each other privately about the arrangement and its power relations, their physical relationship and the sexual forces that shaped it. As private and intimate as it is, though, the book also turns an unblinking light on a period of intense upheaval between men and women. Looking back now, thirty years later, this extraordinary couple — who are still together — are willing to reveal their most private moments to our scrutiny. What they capture in The Mistress Contract is an unapologetic revelation and a bold provocation.
