A prostitute tried to extort $15,000 from a married Missouri man — secretly recording their illicit encounter, and posting the sordid scenes to Facebook, court documents show.

Kailynn Havannah Alexandria Moore-Jones, 22, filmed herself getting intimate during a threesome with the St. Louis County man and another woman after meeting him on an escort website in August, according to federal court documents cited by the St. Louis Post-Dispatch.

Moore-Jones then barraged the man with a series of calls, texts, emails and Facebook messages demanding that he pay $15,000 or else she would post the hot and heavy footage of their session, FBI Special Agent Kassandra McKenzie wrote in an affidavit.

The jilted john ultimately sent $2,200 in three wire transfers to Moore-Jones, but she wasn’t satisfied with that haul and wanted more money. She later posted a graphic video of her encounter with the man on his Facebook page, as well as his wife’s and employer’s, according to the affidavit.

The victim turned to the FBI for help in August and called Moore-Jones two days later as investigators listened in. She agreed to delete the footage if the man sent more cash, the affidavit states.

Moore-Jones, who could not be reached for comment early Tuesday, was arrested in late August in Tucson, Arizona, where she picked up two of the wire transfers at a Walmart, authorities said.

She pleaded not guilty on Monday to extortion in US District Court in St. Louis, the Post-Dispatch reports.
