A 69-year-old grandmother has revealed how president John F Kennedy took her virginity in a sordid affair that lasted 18 months.

Mimi Alford claims that Kennedy seduced her on his wife's bed, told her to engage in sexual acts with an aide while he looked on and made her take drugs.

The extraordinary revelations were made in her newly published autobiography, which even go as far to claim that she assumed she was pregnant with the president's baby.

In Once Upon a Secret, Alford also says that the aide arranged for her to have an abortion, despite it being illegal at the time.

Her affair with the president allegedly began in the summer of 1962 and continued until he was assassinated in November 1963, when she was just 19.

Alford also discusses that the pair never kissed and how he would completely ignore her when his wife was in the office.

Following an evening of cocktails, Alford said the president led her into his wife's bedroom and removed her clothes without so much as uttering a word to her.

When she recoiled, the president reportedly asked: "Haven't you done this before?"

She replied: "No." Afterwards, on her way home, Alford said she kept thinking that she was no longer a virgin.

"The fact that I was being desired by the most famous and powerful man in America only amplified my feelings to the point where resistance was out of the question," she said.

She also recalls an evening at Bing Crosby's ranch where the sex drug amyl nitrate was being passed around and Kennedy forced her to take it.

"I was sitting next to him in the living room when a handful of yellow capsules - most likely amyl nitrate, commonly known as poppers - was offered up by one of the guests.

"The president asked me if I wanted to try the drug, which stimulated the heart but also purportedly enhanced sex.

"I said no, but he just went ahead and popped the capsule and held it under my nose. He didn't try it himself. This was a new sensation and it frightened me. I panicked and ran crying from the room."

Alford also revealed that, after a few months, the president "dared" her to perform oral sex on his aide, Dave Powers, because he "looked a little tense".

She last saw Kennedy a week before he was killed. He said he would call her, but he never did.
