A math and religion teacher in Sydney was jailed for a year for having a sexual relationship with her 15-year-old student in 2008. Four years later, she pleaded guilty to three counts of aggravated sexual intercourse when the boy, now aged 20, reported the matter to the police.

"When I was 15 she made me feel excited and powerful but as I matured I felt ashamed, angry, guilty and confused," the victim said. He also told the court that he suffered from depression and anger management issues.

The 51-year-old teacher and mother of three had a breakdown after her failed marriage, which led her to inappropriately deem the boy's request to help with math as something special.

Judge Colin Charteris stated that the victim also pursued the teacher. Even before the relationship started, he tried to grab the teacher's breasts as a dare.

"That does not excuse the offender's conduct," Judge Charteris said. He noted that the boy was only 15, and the teacher was 46 at the time.

"It's elementary to any school teacher that it's improper to engage in any sexual activity with students who are not able to render consent." He also added that "she was a mature woman" and that "she knew well what she was doing wrong."

Next July, the teacher is already qualified for parole. The judge accepted that she was genuinely remorseful, felt "great shame" at her actions and was "vulnerable" at the time.

"(But) she has paid a significant price for her foolish conduct," he said.

Meanwhile, another similar case happened in Worcester County, Massachusetts when a female sex education teacher had sex with her 14-year-old student on several occasions.

According to Sentinel & Enterprise, a local newspaper, Rachelle Gendron had sex with the victim in January 2013, March 2013 and three times in October 2012.

Gendron, 27, faces a state-mandated sentence of 10 years in prison if found guilty of enticement of a child under 16 years and five counts of rape aggravated by age difference. CBS Boston reported that evidence against Gendron includes texts and photos sent via text wherein she was "in various states of undress."

Her attorney, Andrea Levy, told reporters that Gendron pleaded not guilty and maintains her innocence.
