In an old-fashioned classroom, Harmony's young harlots are meant to be learning, but detention turns into a playground for their insatiable desires. The girls, clad in short pleated skirts and white blouses, start to squirm in their seats, their eyes locked onto the teacher's assistant, a handsome young man. They begin to touch themselves under the table, their breathing growing heavier as they imagine him. Boldly, one girl stands up, her skirt riding up to reveal her panties, and approaches him, offering herself. The others follow, the room filling with the sounds of moaning and wet flesh as they take turns pleasing him, their detention turned into a sexual free-for-all.
