Tina Marie Arie and Howard Windham were arrested on drug charges last Monday after a police officer responded to a Whataburger in Montgomery County, where a male acquaintance of Arie and Windham was passed out.
Arie, 44, who admitted providing the unconscious man with Hydrocodone, was arrested for delivery of a controlled substance.
Windham, 30, was found with the muscle relaxer, Soma, and arrested for possession.
The pair was cuffed and placed into a police cruiser to get booked.
According to a spokesperson for Montgomery County Constable Precinct 4, at one point, the officer looked in his rear view mirror and he "could no longer see Tina Arie," who subsequently explained she was resting her head in Windham's lap because she was "tired."
Suspicious, the officer pulled over to the side of the road to investigate, according to a press statement.
He discovered that, "despite being handcuffed behind their backs," the pair were engaged in a sexual act. Windham's jeans were undone."
It is unclear how Windham's jeans were unfastened.
A spokesperson said Arie was unaware whether the jeans were of the zipper or button-fly variety.
The officer "ordered them to cease sexual contact."
Though Arie and Windham could have faced an additional public indecency charge, investigators opted not to tack on a misdemeanor count to the more serious felony narcotics charges.
