Brandon Lee Aaron, 27, was arrested by police in the small town of Panama after sending explicit, sexual texts to the girl, the Tulsa World reported.
An older sister helped police find Aaron, after she reported the sexual relationship between her sibling and the man.
The 15-year-old told social service workers she twice had sex with the man. After being asked if Aaron had identifying marks not visible when he was clothed, the girl replied he had a tattoo of his ex-girlfriend’s name on his penis.
Aaron was arrested on Sept. 22, the paper reported.
After denying he had sex with the teen, Aaron later told police he “knew it was wrong.”
He is being held at the LeFlore County Detention Center in western Oklahoma, in lieu of $25,000 bail. He is charged with two counts of second-degree rape.
