Mr. Playboy: Hugh Hefner and the American Dream is set to hit bookstores later this year, and Playboy founder Hugh Hefner has called it “the most authoritative book ever written about me.”

In the book, author Stephen Watts tells of Hefner’s Chicago hook up with another man and a foursome he had with his brother, his wife and his sister-in-law.

The book chronicles the many sexual encounters Hefner has had over the years, including two tales that, as of yet, have gone unreported on the 82-year-old media mogul’s life.

In the book, Watts writes: “Hefner’s thirst for sexual experience became so strong that he even had a one-time homosexual experience.

“One evening in downtown Chicago he was propositioned and, according to Sellers, he ‘thought, what the hell. Found it an interesting experience. As far as I know, the guy just gave him [oral sex].'”

He goes on to tell of his three-way, foursome and group sexual encounters, saying in one four-way, he had sex with his sister-in-law while his brother watched.

Tell alls such as these are frequently done without the consent of the subject, but Hefner has given this book his seal of approval, saying, “it’s all essentially true,” according to Towleroad.
