At about 4:30 a.m., deputies responded to a call about a prowler in the area nearby Countryside Baptist Church.
As deputies checked the area, they saw a man and a woman walking down the road together. The man told deputies that he was walking the woman back to her house.
Deputies then determined that the man and woman were brother and sister—and that they had just had sex in a tractor trailer parked outside of a church.
The church also happens to be across the street from a school.
Christopher Buckner, 20, and her half-brother Timothy Savoy, 24, were arrested after admitting to having had sex three times in the tractor trailer.
The pair apparently told the officer that they decided to have sex after watching The Notebook.
WJCL reports that the couple was charged by police with incest, sodomy and prowling.
