One of the teachers at a small Missouri high school is in hot water for peddling porn on OnlyFans to supplement her income. A student slipped a note under her classroom door to let her know.

X-rated moonlighting job revealed Friday led Megan Gaither, 31, an English teacher and varsity cheerleader coach at St. Clair High School, to be put on leave.

Teaching doesn’t support you financially. Summer paychecks take a lot of work to stretch. According to her, that’s why she did it.

As of last year, Gaither earned about $47,500, including a coaching stipend, from the subscription-based site.

She was placed on leave after it was revealed she was running an OnlyFans page with her husband, and her colleague Brianna Coppage resigned to devote all her time to porn.

After district officials learned about Coppage’s scandalous side gig to supplement her measly $42,000 salary, she was suspended on Sept. 27.

After ditching her teaching duties and making global headlines, the former teacher made close to $1 million selling porn.

After school officials discovered Coppage’s account, Gaither deactivated her OnlyFans account, which had about 1,500 subscribers.

At the time, she made about $3,000 to $5,000 a month on OnlyFans but kept her face hidden.

But rumors started spreading among students when she appeared in a video on Coppage’s page. According to the paper, while her face wasn’t visible in the video, which was shot in a hotel room, a photo from the party showed her wearing the same outfit she wore in the video.

“I wasn’t there for more than four minutes, and I definitely didn’t think it would ruin my career,” Gaither told the Post-Dispatch.

On Friday, Gaither called Coppage her best friend. They found out they were both on OnlyFans in June when Gaither made an offhand remark at a Busch Stadium teachers’ night.

Although she insists she has never acted unprofessionally and has gotten good reviews from school officials, she says the district put her on leave for “professionalism and student communication.”

She said: “I love every single one of them. They are why I said I would spend 30 years in that school, and I feel like I am abandoning them. I know I won’t see them again.”

She’ll likely reactivate her OnlyFans account since she and her husband have already discussed moving.

“All I’m trying to do right now is make enough money to support my family,” she told the paper, adding that other teachers might do the same.

Teachers are probably freaking out right now because two teachers from the same school have been caught in less than a month.
