A Bexleyheath Academy assistant vice-principal had sex "all over the school" with a pupil, a court has heard.

Stuart Kerner, from Aylesford, is accused of six counts of sexual activity with a child and two counts of sexual activity with a child by a person in a position of trust. He denies the charges.

The 44-year-old's trial began at Inner London Crown Court today (November 18).

It is alleged many of the sexual encounters took place at Bexleyheath Academy in Woolwich Road and one day "in bed" at his house in Russett Close, Aylesford, when his wife was away.

Prosecutor Warwick Tatford said: "They had a nice time and it must have been very exciting for her, like they were some kind of married couple.

"We say this was a breach of trust, a teacher giving into temptation and conducting a full-blown affair.

"They had sex or sexual activity in a number of different rooms, all over the school.

"She sought this relationship and like many many modern teenagers she had a wide sexual knowledge."

On one occasion it is claimed Kerner praised the teenager on her sexual technique.

It is also alleged Kerner falsified school records to keep their affair secret.

Mr Tatford told the court that on one day the girl was marked absent from class but the record was later changed by someone using the login of Stuart Kerner.

Mr Tatford said: "He wanted to cover his tracks to say she was in class when in fact he was having sex with her on the other side of the school."

They allegedly had sex in the classroom with Kerner keeping many of his clothes on, including his waistcoat, tie and shirt.

The charges range from March 31, 2011 to November 30, 2012 when the schoolgirl was 15 and 16 respectively.

Kerner was arrested on January 28, last year.

He has more than 20 years of experience as a teacher. He taught religious education, politics and ethics at the school. 

The trial continues.
