An Arizona couple was arrested for having threesomes with their 15-year-old babysitter — even going so far as to film one of the romps, authorities say.

Jeffery James Swartz, 27, and Samantha Ohlman, 23, were arrested Wednesday after the victim, now 16, told Maricopa County Sheriff’s Office detectives about the alleged trysts with the couple — whom the teen met through her brother before getting hired to watch their children, KPHO reports.

The victim and her brother, according to court documents obtained by the station, went to the couple’s home in Tonopah in May to help them with their swimming pool. Ohlman then began to ask the girl if she wanted to have sex with her and Swartz.

“The victim replied she didn’t know if she wanted to and said it was awkward because of their age differences,” the court documents read. “Sammie invited the victim to spend the night at her house and the victim accepted.”

Ohlman later showed the girl several sex toys and some lingerie before Swartz returned home from work, according to court documents. After several offers and an oil bath drawn for the victim, the girl finally relented, telling detectives she “felt pressured” to have sex with the couple after their multiple advances.

The three then had sex, court documents show, before a second encounter at the couple’s home in mid-July. The victim said Ohlman grabbed a camera from a nightstand during the second tryst and began to record her having sex with Swartz.

“The victim reported that she asked Sammie not to record her, however she continued recording her,” the documents continue. “After Sammie and Jeff had sex, Sammie told the victim that they always record the time they have sex with other people and she showed the victim a video of Jeff having sex with another female.”

The girl told her grandmother about the encounters Aug. 1 and she notified authorities. Detectives later interviewed Swartz and Ohlman at their home, where Swartz denied the allegations.

Ohlman, during a separate interview with detectives, admitted to the trysts with the teen. She also told investigators that Swartz recorded sex acts with the girl but said she believed the footage was deleted, court documents show.

Swartz and Ohlman have been charged with one count each of sexual conduct with a minor, furnishing obscene material to a minor, sexual exploitation of a minor and luring a minor for sexual exploitation. They are scheduled to appear in court Sept. 7, jail records show.
