A sicko Queens teacher known as “Mr. Blunt” sexually abused a junior high schooler for two twisted years, plying her with pot and porn, the girl claimed in a lawsuit.

The unnamed educator and guidance counselor tormented the accuser from 2000 to 2002 while she attended Junior High School 189 in Flushing, threatening to report her marijuana use if she revealed what was going on, she contended in a Queens Supreme Court lawsuit filed against the city and the Department of Education.

And when the alleged victim — whose name is being withheld by The Post — tried to avoid him by telling him she was menstruating, he “demanded that [she] show him soiled sanitary napkins and/or tampons,” she alleged.

“At a time when [she] should have been enjoying sports, interacting with her peers, and focusing on her studies,” the educator was instead forcing the student to “watch pornographic videos and endure intense sexual harassment, and sexual assaults,” the accuser claimed in court papers.

“Due to the trauma,” the student does not remember the teacher’s real name, the lawsuit claimed.

She remembered her abuser only as Mr. Blunt — based on his giving her weed or “blunts.”

The former student is suing for unspecified damages under the Victims of Gender-Motivated Violence Protection Law, which opened a two-year legal window for victims to bring past claims of sexual abuse to court.

The city Law Department said it would review the case when it was served.
