A married teacher let out a bloodcurdling scream as she was jailed for a year after having sex with a schoolboy.
Lauren Cox, 27, let out a screeching cry as a judge sentenced her to 12 months in prison today.
The teacher admitted a having a 6-month-long sexual relationship with a 16-year-old boy, which was discovered by his mother.
Cox also said "I'm sorry" to her tearful family sitting in the public gallery as she was taken to the cells at Croydon Crown Court.
An emotional exchange took place between the victim's mother, who undertook her own investigation to expose the abuse, and Cox's mother.
Cox's mum burst into tears as her daughter was sentence, and the victim's mum said to her as she exited the room: "I didn't have a choice, he is my son."
Her mother replied: "You did have a choice. How do you sleep at night?"
Judge Adam Hiddleston jailed Cox for 12 months after commending the boy's mum for the way she handled the situation.
He said Cox kept the relationship secretive, but the boy's suspicious mum spotted him getting into her car before contacting her telling her to resign and never see her boy again.
Judge Hiddleston said: "Her calm and sensible reaction to this came to her as she suffered considerable shock.
"After you made a full confession you begged to break the news and she allowed you do to so.
"And then you didn't do as you said. At that further meeting you had sex with him again in a flagrant breach of trust instilled in you by his mother.
"Despite being warned to desist by the victim's mother you offended again."
Judge Hiddleston accepted that she groomed the boy, having known him before he turned 16.
She began grooming the boy just six months after she was married, and was forced to move into her parents' home once it was discovered.
He said: "The relationship between you and the victim changed, one would say, across the line.
"The effect on the victim has been considerable. He described how you emphasised the need for secrecy which led him to distance himself from his friends and family.
"The constant need to lie led to him becoming depressed."
The judge took into account her guilty plea and that she had destroyed her chances in the career she had excelled in.
He said: "In all likelihood you will never be able to work with children again.
"You did break all of the rules, rules you were very well aware of.
"You have brought shame and disrepute on yourself but you have so taken a very noble profession into disrepute.
"I don't believe I would be doing my duty if I did not send out a message loud and clear that betrayal in this situation must result in an immediate custodial sentence."
Crying throughout the hearing, she found herself unable to look at her family in the public gallery but apologised as she was led to the cells.
Cox wrote an impassioned letter to the judge apologising for her actions but vowed she would fight to teach again.
In it, she wrote: "I fell in love, I made him happy and the feeling, I believe, was mutual.
"If there's even a minuscule chance of me being able to resurrect my career I will fight for it with everything I have."
Brian Reece, prosecution, described the impact the relationship has had on the boy.
He said: "For anyone who reads about this who might make jokes about 16-year-old boys who might queue up for this offending, in the real world [the boy] must deal with the consequences."
Cox, of Oxted, Surrey, will also be placed on the Sex Offenders' Register for 10 years.
Cox seduced the boy after giving him a lift home from school and encouraging him to hug her.
The relationship then developed, and the pair had sex in her car , at her marital home and in his family home.

She also send him explicit photographs, including pictures of her naked and performing sex acts.
Croydon Crown Court heard suspicions about the illegal relationship was first raised by the boy's sister, but the full details were only emerged after his mother began to investigate.
Brian Reece, prosecuting, said the pair first time became close in February last year.
She then encouraged the boy, who cannot be named for legal reasons, to continue by messaging him on a social network where she promised to take him out when he reached sixth form and spoke about her difficult personal life.
Cox continued to give him rides in her car and they ended up kissing and told him to keep their relationship secret.
The next time in her car she got the boy to touch her intimately on March 16 and either later that month or in April they first had full sex.
Mr Reece said: "The sex continued between them and they met at least once each week.
"Four or more incidents were at her matrimonial home.
"And there were a few occasions where it happened at [his] house, where they were taken by surprise.
"They thought they had managed to slip out (of the house) but they were wrong.
"It was that information, in the hands of the mother, that would lead to the exposure and ending of the relationship."
The victim's sister came home on May 9 and Cox slipped out of the house but the child noticed her car and spotted her sandals.
The boy confessed to his mother and a forensic examination of the car by police in September discovered traces of his DNA.
Cox was arrested in September last year after the head of the school, which cannot be named for legal reasons, was alerted and then told social services and the police.
Her lawyer, Ronnie Manek, defending, said Ms Cox truly loved the boy and was suffering throughout from depression.
He asked the judge to suspend any prison sentence adding: "She is ashamed of her behaviour, extremely ashamed.
"Once on that merry-go-round of emotions she found it hard to get off. She herself got into a relationship with an older man when she was 19."
Cox pleaded guilty to five counts of sexual activity with a boy aged 13 to 17.
She admitted of sexual touching with the boy on two occasions in March last year as well as sexual intercourse between April and September whilst being in a position of trust.
