Rarity Belle, caught smoking behind the school.

Sunset Shimmer, caught bullying two freshman.

Both of them are going to be spending their Friday afternoon in detention with everybody's "favorite" literature teacher, Midday Sun. They expect this teacher to give them the occasional scowl before they're allowed on their merry way for the weekend. But what they don't know is that Principal Celestia has granted him special permissions after reinstating domestic disciplinary actions.

Miss Belle and Shimmer will have a lot to think about after both of them get a firm spanking.
