Two schoolgirls are put through an extensive caning session by their headmaster, with a sadistic prefect enjoying her power over them. The girls learn a lot about each other, and about life, in the course of the afternoon. Later at Jennifer's home, her dad gets excited when he sees the marks on her bum. And then mom gets involved, offering to persuade the headmaster to let the girls off further spankings. Mother ends up taking far more from him than she intended.
