*In a tabloid one-two punch, the National Enquirer is reporting that O.J. Simpson had sex in prison with a transsexual who is HIV-positive, and Radar Online has the woman on video giving her detailed account.

(Radar Online and the National Enquirer are both owned by publisher American Media.)

According to their reports, it all went down at the Lovelock Correctional Center in Nevada, where O.J. has been serving time since 2008 for a botched robbery and kidnapping.

In the video posted on Radar, HIV-positive transsexual Jazmena Jameson claims she and Simpson got it in on several occasions.

“I was the closest thing to a real woman,” she told Radar, claiming they began having sex in 2013.

“I used to be the lead porter for the laundry, so I was responsible for O.J.’s laundry,” Jameson said. “I would deliver laundry to his room.”

“We used to joke around and stuff, and finally one day he said, ‘You have big titties. Are those implants or the hormone shots?’” Jameson claimed. “And he wanted to see them … I don’t mind showing anyone, you know, so I ended up showing them to him. He said, ‘You better get up out of here!’”

Simpson looked, but didn’t touch, she claimed. One month later, it was a different story.

“I ended up having oral sex with him,” Jameson alleged.

“I went in there, and we were just … flirting. I’m very flirtatious like that,” she said. “I ended up teasing him, dancing for him … I walked up on him and said, ‘You can stop me if you want to.’ I knew he wasn’t going to stop me … Then it was too late …”

“I kept talking to him and it got harder,” she said. “I gave him oral sex … I made sure he reached his climax.”

But the cellblock hookup could come back to haunt him — because Jameson says she’s HIV positive.

“I’m HIV positive. I have to be really careful,” she said. “I guess that wasn’t being completely careful.”

“It would have been an extremely small chance” that he contracted HIV, she said, but a chance nevertheless.
