A teacher has been jailed after a horrifying sexual affair with a 15-year-old boy pupil.
The schoolboy was so devastated by the then-25-year-old Fay Mcrobbie's sexual demands that he confessed he'd considered sexually harming himself in a bid to make himself less attractive to the woman.
The story of the learning support assistant's illicit affair with a boy 10 years her junior was revealed in court at a sentencing hearing which saw Mcrobbie jailed for more than two years.
Oxfordshire educator Mcrobbie, now 32, groomed her student into joining her martial arts class, where she kissed him and began a romantic relationship.
Reading Crown Court was told that she was planning a future for the pair, while the boy felt under immense pressure as her emotional crutch.
The victim, now in his early 20s, stood up in crown court to express how the teacher's controlling behaviour had deeply affected him.
"Fay was relying on me emotionally, I felt responsible for her feelings," he said.
"The relationship only got worse, arguments were getting more frequent and the reasons were getting more silly each time. I was becoming severely depressed as I could not speak to anyone, Fay was my only friend.
"As I was going to be leaving school and going to college, I wanted to stop talking to Fay but she was planning a future for us."
When he told her it was over and he had a new girlfriend his own age, she "broke down" and threatened suicide, he said.
"At the time I would have done anything to get her away from me, I even considered genital mutilation - I thought if I had nothing there to interest her then she might leave me alone."
The "wholly inappropriate" relationship began while Mcrobbie was teaching the student at school in Wokingham, Berks.
She invited the boy - with the school's knowledge - to her martial arts training classes. The pair would travel to the sessions together, allowing their "friendship to flourish into a relationship," prosecutor Robin Miric said.
Sitting at Reading Crown Court, the judge heard how the couple first kissed outside a martial arts class during a play fight which led to participating in "mutual masturbation" in the training hall on at least 10 occasions.
"One day before training, we were play-fighting when things took a turn and we kissed," the victim said.
"Before this point, I did not have any interest in girls, it was unexpected for me. After this, we would get to training early so we could do more sexual stuff.
"Over the summer holidays we went to a friend's house, this was the first time we had sex. I felt I wanted to run away, I was very much not ready, it was the first time I was naked in front of someone else.
"I felt dirty, I could not stand the sight of myself in the mirror and I felt my innocence had been taken away."
After the relationship had turned sour, the victim later disclosed his secret to an employer who, with his permission, informed the police.
Mcrobbie was arrested on May 16, 2019, and gave a "no comment", interview but later admitted three counts of causing a child to engage in sexual activity.
Defending the sobbing teacher, Robert Slinn said: "Fay is appalled by her actions. She has gained a real insight into the lasting damage her behaviour has had on the victim. She knew it was damaging at the time but she was fatalistic in her own view.
"She was unable to view a future for herself, she was seeking validation. She knew that this relationship was, from the outset, a breach of trust and wholly wrong.
"Her relationship with the victim was, although wholly inappropriate, a genuine affection. Despite being completely misplaced, she believed she was in a relationship. Now, her reputation is forever marked."
During sentencing, Judge Paul Dugdale said Mcrobbie had committed a "gross and terrible breach of trust".
He said: "You involved him in a full relationship, he was far too young and vulnerable to be in that state with anybody let alone an adult who is 10 years older than him.
"The reality is not only were you acting in breach of trust, having a sexual relationship with a pupil 10 years younger than you, but you were also behaving in a controlling coercive way towards him because of the perception that you were in a relationship and you needed him to support you in the difficulties in your life.
"You used him for that purpose as well as using him for your own sexual gratification. He was not remotely able to deal with it and you caused a lot of damage. I have taken into account everything I have read about your mental health but while that may be an explanation, I am afraid it is not an excuse."
Mcrobbie was jailed for two years and four months and will be subject to a Sexual Harm Prevention Order for 10 years.
