Most political and pop culture watchers believe that Robert F. Kennedy, left, and John F. Kennedy, right, had an affair with Marilyn Monroe, center.

Most people are well aware that the Kennedy brothers were all-time freaks. But this takes the cake.

An oval office orgy featuring former President John F. Kennedy, former attorney general Robert F. Kennedy and legendary blonde bombshell Marilyn Monroe is allegedly about to go on auction, the media reports.

A former Hollywood bodyguard says the steamy, never-before-seen reel — said to have been shot on 8 mm film — will be auctioned by the Tulare County Sheriff in California which has seized the property as part of a lawsuit involving William Castleberry.

Castleberry told RadarOnline.com that the sex tape of JFK, RFK and Monroe “is real. I had it for years and I never released it out of respect for Joe DiMaggio … I’m just sick about it and I’m desperately trying to raise money to get it back.”

Castleberry, 56, is a memorabilia collector. He refused to divulge how he obtained the never-before-seen sex tape or what exactly is on the tape. 

The issue came to pass because Castleberry was hit with a judgment of $200,000 after he allegedly sold a fake statue to several people in Visalia, Calif. Castleberry had been working to satisfy the judgement but, according to Castleberry, the lawyers demanded a balloon payment that he simply couldn’t handle.

“They demanded a $90,000 payment I couldn’t afford and that is when the sheriff came in and seized the sex tape and all of my other memorabilia I have been collecting my entire life,” he said.

The lawyer for the plaintiffs said he heard that there was an explosive tape of the iconic trio that was among the items seized from Castleberry’s property.

“I was told several years ago that Mr. Castleberry had a sex tape of Marilyn Monroe, JFK & RFK,” said attorney Ryan Sullivan, who is representing the plaintiffs in the case against Castleberry.

“I was at the house when the sheriff was seizing the property. I’m simply trying to recover the money for my clients… I was able to locate a 8 mm film in a canister at the house, which was turned over to the Visalia Sheriff’s Department.”

Sullivan was trying to tame the rising excitement. “I have no idea what is on the tape, it could be what Mr. Castleberry says, or it could be a Disney cartoon. The only way anyone will ever know is if they buy it and view it. The entire lot will go up for auction on Tuesday and the minimum bid will be $200,000.”

Rumors have run wild for decades that Monroe, who died in 1962, had affairs with both Kennedy brothers, but not at the same time. This would mark the first time that it’s been alleged that the woman born Norma Jean had sexual intercourse with JFK and RFK simultaneously.

A desperate Castleberry said he is trying to raise money before his stuff goes up for auction.

“Mr. Castleberry has until Tuesday morning before the lot goes up for auction to get his stuff back,” Sullivan said. “He would have to pay over $200,000 to satisfy the judgement. If he fails to do so, the auction will proceed.”

If he does secure the apparent prized possession, Castleberry said he plans on “releasing it all to the world.” He said, “I had hoped to give it all to a museum, or even open one myself. If I don’t get it back, well, okay. It’s just stuff and I can start over. My wife is extremely sick and when I go to heaven someday, I’m not taking a U-haul full of stuff with me.”

Other prized possessions seized included a signed Babe Ruth jersey and books by Thomas Edison that were also signed by the inventor.
