Sandrine Brown, 31, got close to the first pupil when she was only 13-years-old in May 2008. The teacher, who was head of girls PE, then started talking to the teen online before swapping numbers. A court heard they started a sexual relationship when the schoolgirl was just 14 after becoming close during the summer holidays. The youngster regularly slept over at Brown's flat in Stoke, Coventry, and engaged in sexual activity with her in her car. They even had a sexual liaison in a school store room. Brown then made contact with the girl's friend, starting a relationship with her in January 2010. The girl was only 16. The jury were told how she then spent time with both girls, who can't be named for legal reasons, in a hotel room in February 2010. Brown admitted one charge of inciting a child to engage in sexual activity while in a position of trust as a teacher. She also pleaded guilty to five counts of sexual activity with a child, again while in a position of trust. She showed no emotion as she was jailed for only 18 months at Warwick Crown Court today. Judge Richard Griffith-Jones, the Recorder of Coventry, said: 'This case is a tragedy. 'Most particularly it is a tragedy for the two now young women who were young girls at the time that they were sexually abused by you. 'But it's also a tragedy for you because you were blessed with intelligence and athleticism and sensitivity. 'Young people whose emotions are developing, whose bodies are developing, whose characters are not yet formed, who are there to be set examples by people like you to aspire to and mould their characters. 'It's very often the case that young teenagers look up to people who teach them and regard them as role models and inspirations 'There couldn't be a greater betrayal of that responsibility to have these developing young people in your care and then to be so weak and self-indulgent as to take advantage of them sexually as you did. 'I have to send you to prison because of that gross breach of trust and the effect it has upon the people who are the victims. 'They will carry it with them, as you will, that's the terrible damage.' He added: 'The other aspect which compels me to take the course I'm going to have to is that this involves a matter of public confidence. 'Think if the thousands of parents who send their children to school thinking they are being looked after and this happens.
