John Kennedy was a pretty randy guy according to Mimi Alford. She was a 19-year-old and worked as a White House intern when she says she began an affair with President Kennedy. The details of that alleged affair are recorded in her new memoir, "Once Upon A Secret: My Affair With President John F. Kennedy." According to jornalists who received an advanced copy of the post, JFK's friend Dave Powers allegedly gave Alford several daiquiris to drink at the pool before the president arrived and whisked her away into the White House. Steamy details of the ensuing sexual encounter follow, including the fact that Kennedy kept his shirt on. According to Alford, the president had sex with her in Jackie Kennedy's bedroom (his wife and American first lady). They only allegedly did it there once though, the first time. After that, she claims they kept their affair to JFK's bedroom, according to the New York Post. She says that the president had a kinky side. In talks with Alford, he allegedly tried to get her to tell him naughty things she did as a schoolgirl.

According to the book, he allegedly made Alford wait in a hotel room for hours until he called for her. Usually, he would only call at night. Alford called this "the Waiting Game." Other times, Kennedy allegedly made steps to ensure the affair would be kept secret, according to the New York Post. When Alford told Kennedy she had met Lyndon Johnson, she claims he told her to stay away from the vice president, fearing that Johnson could use his knowledge of the affair to his advantage.
