A married city teacher at a Brooklyn high school where two of her colleagues carried on a sapphic tryst had a month-long sex romp on the campus grounds with her 16-year-old student, a new court filing says.

English teacher Erin Sayar, 35, is accused of having sex with 11th-grader Kevin Eng at least eight times last December when she was supposed to be tutoring him. The trysts happened in her SUV and at Brooklyn’s scandalized James Madison High School — which was dubbed “Horndog High” in 2009 when two female teachers were axed after two handymen caught them in a naked embrace in a classroom.

Sayar also plied her pupil with pot she kept in a work file cabinet, according to court documents the teen’s family filed in Brooklyn Supreme Court on Wednesday.

“I love you so much,” Kevin wrote his teacher in one Facebook message, according to a Department of Education investigation report.

The affair may have continued if not for the teen’s jealous girlfriend, who hacked into his Facebook account and discovered the steamy messages between Sayar and him, the filing says.

The girlfriend then snitched to school officials, who informed the student’s mother in January.

Kevin, who’s now 17, initially denied any hanky-panky but eventually ’fessed up to an investigator in late March.

He acknowledged that Sayar picked him up from his home past midnight on one occasion. “Eventually, they began kissing and then engaged in sexual intercourse and oral sex inside the SUV,” the DOE report said.

He also described tattoos on intimate parts of Sayar’s body. Investigators also pored over the teacher’s cell phone records and found she and Eng exchanged an astounding 3,856 text messages during a 17-day period last December.

“As parents, we entrust our teachers with the care of our children to cultivate and nurture their foundations, not to exploit their innocence, nor rob them of their childhood,” the family’s lawyer, Bruce Baron, said.
