A Brooklyn teacher caught naked in a lesbian sex romp was given the heave-ho this week — after ridiculously claiming that she ended up naked and sweaty with a colleague on a classroom floor because she was being treated for low blood sugar.

Spanish teacher Alini Brito, 30, said colleague Cindy Mauro led her into a darkened classroom at James Madison HS for an insulin shot and candy when a dizzy spell forced her to the ground.

“[I] started getting those — my heart beating fast, a little dizzy, and I knew that I wasn’t feeling well,” she told school officials regarding the November 2009 incident.

Brito said she ended up on the floor with her feet propped up on a chair while Mauro knelt beside her.

But testimony from two school janitors and a school safety agent who walked in on the duo that night disputed Brito’s account.

The safety agent said she saw Brito “naked on the floor with her legs kneeled, like in a birthing position, and I saw the blonde between her legs.”

“When I opened the door, she looked up and told me to shut the door, shut the door,” the agent added.

Hearing officer Mary Crangle dismissed Brito’s claims and slammed her conduct as “outrageous” and “unprofessional” in giving her the boot.

A decision on Mauro’s fate is pending.

“There is no possible medical, nonsexual assistance that a partially naked person could possibly be rendering to another naked person in the position described,” Crangle’s report read.

The action in Mauro’s third-floor classroom occurred as students were performing in a music competition in an auditorium downstairs.

“It is clear that [Brito] can no longer garner the respect that is necessary for an effective teacher, nor any longer be a role model for students,” the report said.

Several attempts to reach Brito, who is married, were unsuccessful.

But she and Mauro both disputed the allegations that they were naked or drunk.

The report said they had spent more than three hours at a local bar before returning to the school performance.

Brito also said the claims against her came in retaliation for a discrimination complaint she had recently filed against a fellow teacher.

But Assistant Principal Jodie Cohen, who was called to the classroom, said Brito had been singing a different tune that night.

“Alini came over to me and grabbed my arm and begged me, and said, ‘Jodie, please, please don’t say anything, please,’ ” Cohen reported.
