Marlon Brando enjoyed two nights of passionate sex with Jacqueline Kennedy and wanted to bare the intimate details to the world, a new book reveals.

In "Bobby and Jackie: A Love Story," which details a purported post-JFK assassination affair between Jackie and Robert F. Kennedy, C. David Heymann has obtained passages from Brando's account of how he hooked up with Jackie in 1964. They were in the first draft of the Oscar winner's 1994 memoir, "Songs My Mother Taught Me," until an editor friend of Jackie (by then also the widow of Aristotle Onassis) at Random House insisted they be cut, Heymann writes.

The first time, "according to Brando, [their] three-hour meal included a good deal of drinking ... Jackie and the actor danced and drank. During their dance, Jackie, deeply attracted to Brando, 'pressed her thighs' suggestively into his. They danced again, then sat down and began to 'make out,' " according to Heymann.

He relates: "In Brando's words, 'From all I'd read and heard about her, Jacqueline Kennedy seemed coquettish and sensual but not particularly sexual. If anything, I pictured her as more voyeur than player. But that wasn't the case. She kept waiting for me to try to get her into bed. When I failed to make a move, she took matters into her own hands and popped the magic question. 'Would you like to spend the night?' And I said, 'I thought you'd never ask.' "

A week later, Jackie again hooked up with Brando at a Sutton Place apartment he borrowed from a friend. Commenting on Jackie's "boyish hips" and "muscular frame," Brando said, "I'm not sure she knew what she was doing sexually, but she did it well."
