Allison Marchese, 39, from Connecticut in the United States, sent two teenagers winking emojis, saucy texts and half-naked selfies, a court heard yesterday.
The mum-of-two cried in court as relatives of the boys told of the impact her actions have had on their lives.
One parent said: “The actions done by this woman has caused immeasurable damage to my son.”
Judge Melanie Cradle told Marchese: “You were a teacher and you were in a position of trust. And the bottom line here is the victims are kids and were their teacher.
“A person who is engaged in the noble profession of shaping lives, values and thought processes of our youth.
“It’s certainly a gift you should’ve taken more seriously.”
One of the students, 17, had told police that Marchese called him to her classroom where they kissed.
He also said that she then started touching him “downtown.”
Marchese, whose husband Robert taught at the same school, then locked the door when he entered.
He told police officers that she then closed the blinds and performed a sex act on him.
After the incident he “freaked” out and told Marchese that she should pay him AUD$260 to not tell anyone about what had happened.
But the teacher then threatened him, claiming “her father was an abusive man who had spent time in jail and had contacts in the Mafia.”
Marchese had earlier sent him “weird” sexual messages, the court heard.
She had also shared partially nude photos on Instagram, which could be viewed by other students.
She claimed that one of the X-rated selfies she sent to a student was meant for her husband and she “did not know how a student would have got it”.
Another pupil said Marchese started messaging him “nonstop” when he was 14 through Instagram.
Marchese said she “couldn’t concentrate during class because he was so good-looking and she could not sleep at night because she was thinking about him.”
