A couple is facing criminal charges after they were caught having sex in public at the Wisconsin State Fair, according to police.

Desiree Anderson, 28, and Robert Beasley, 28, were arrested yesterday in connection with their X-rated tryst inside an open air coliseum on the fair grounds in West Allis, a Milwaukee suburb.

Anderson and Beasley--who apparently were previously married to each other--were having sex in the stands of the coliseum, which is the site for horse and dog shows. The duo, seen in the below mug shots, were frolicking in full view of other fairgoers, at least one of whom recorded the couple in action (as seen above).

Upon discovering that he was being filmed by a stranger, Beasley--who was atop Anderson with his buttocks exposed--waved at the camera and smiled. When video of the raunchy duo began circulating online, a State Fair spokesperson responded that the incident was “appalling” and “inexcusable.”
