Lorna Shannon is one of the most senior girls in St. Justs Academy but she is in trouble. A report has been made to the headmaster that she was having some sort of sex with boys from the upper school. At first she denies this and so the headmaster has no option but to spank her bottom. She has to go over his knee, very embarrassing for this senior, her white school knickers are removed and she is spanked as hard as the head can on her bottom for telling lies. But, this will not be the end of the matter.
