A British science teacher had a year-long affair with one of his pupils after having sex with her in a school store cupboard, a court has heard.
Michael Taylor, now a principal, began a secret relationship with the teenager days after she turned 15, the jury was told.
They allegedly met once a week for "music practice" during which the girl performed sex acts on him.
She was told to keep playing the xylophone during the incidents so anyone passing the classroom would not disturb them, the court heard.
Leicester crown court was told the teacher liked to be called "Mr Taylor" during sex, telling the girl: "You've got detention with me at the same time next week."
