JFK's Teen Lover Tells All in Explosive New Book Mimi Alford's 'Once Upon a Secret' recalls Kennedy fling By Neal Colgrass, Newser Staff Posted Feb 5, 2012 3:38 PM CST 49 comments Comments Aaron Shikler painted this posthumous official portrait of John F. Kennedy. (Wikipedia) (Newser) – A former White House intern's shocking tell-all about her affair with President Kennedy has arrived in bookstores. Mimi Alford's Once Upon a Secret recounts her first sexual encounter with JFK at a White House after-party in 1962: The president guided her into Jackie O's bedroom, "unbuttoned the top of my shirtdress and touched my breasts," she writes. After they had sex, he matter-of-factly pointed her to the bathroom. The 19-year-old kept thinking that night: "I’m not a virgin anymore.” The New York Post serves up more details about the 18-month affair: Their sex was “varied and fun.” The pair spent an “inordinate amount of time taking baths." They liked the musical “How to Succeed in Business Without Really Trying” and enjoyed singing it together. But "there was always a layer of reserve between us, which may explain why we never kissed,” she writes. JFK lost his composure after she met Vice President Lyndon Johnson. "Stay away from him," he told her. He once suggested that she relieve the tension of "first friend" Dave Powers during a noon swim. "This was a challenge to give Dave Powers oral sex. I don’t think the president thought I’d do it, but I’m ashamed to say that I did . . . The president silently watched.” During the Cuban Missle Crisis, JFK told her, “I’d rather my children red than dead." The two cried together while reading condolence letters after the death of his infant child, Patrick Bouvier Kennedy. JFK once mischievously suggested that she "take care of my baby brother. He could stand a little relaxation." She "absolutely" refused. See more from the Post here.
