The Queens middle school teacher charged with raping a 14-year-old boy twisted his trust to take advantage of him, the victim told The Post Saturday — and shared some of the sickening messages he said she sent him.

The teen, who The Post is not publicly identifying, said in a phone interview that 33-year-old Melissa Rockensies began grooming him shortly after she began filling in as an educator at his school last year.

“I feel like she took advantage of me because of my age and I was vulnerable with her,” the teen said, noting he began emailing her over a problem he had with another kid at school.

“I felt comfortable with her. I’m smart but I don’t make good decisions. I work off of impulse. If someone says let’s go do something I’d say all right let’s go do it.”

The mother of three soon began messaging him on Instagram, he claimed, and over the course of almost a year fired off a barrage of depraved messages, which she then urged him to delete.

“Oh and delete the chat okay love you byeeeeeeee,” Rockensies allegedly wrote to the victim, who provided screenshots of the message and others to The Post.

“You’re gonna be lucky once I put this kid to sleep,” she allegedly wrote in one exchange shared with the Post, referencing her own children.

In another, Rockensies allegedly wrote: “I want you so bad and now I gotta go read kids books like …wtf.”

She also allegedly wrote to the boy: “Study up on your technique and I’ll be moaning for you all day and all night daddyy” and “I wanna be able to kiss those lips of yours.”

The teen said he was stunned when the Corona Arts and Sciences Academy dean — who once posted online about helping kids understand consent — first abused him.

In September, after allegedly exchanging hundreds of emails, the pair began messaging on Instagram, with Rockensies eventually suggesting they meet up in person at a supermarket, he said.

They went on a walk in a park afterward, where the teacher hugged the boy “really close” and said “she wanted to kiss me,” the teen recalled, noting she followed through and kissed him.   

“This came out of nowhere. I wasn’t expecting it because she said she has a husband and stuff. I felt weird like I had to hug her back. I hugged her. I kissed her. That’s how it started.”

The alleged sexual abuse lasted until late May or early June, the teen claimed, noting he usually met Rockensies before or after school and sat in her car.

“She’d tell me where to go to meet her, where the car is parked,” he said, noting they met up almost every day except Wednesday, when “she had to watch the kids.”

“Every time we’d meet up, we’d have sex.” 

Rockensies also gave the boy money and bought him gifts, including nicotine devices, he claimed. 

“Most of the time she [gave] me money,” he said.

“The most she ever gave me was $500.”

Last month, the teacher claimed the teen had threatened to gun down her family if she didn’t fork over $5,000 and reported him to the principal, police sources said.

The student rebuffed the allegations he had threatened Rockensies, claiming he had been grounded from Instagram after skipping summer school — and that someone else had been messaging her from his account. 

After the threats were reported to authorities, the teen said he went to the police and showed them their sexually explicit messages.

The teen’s grandmother said she was disgusted by the abuse.

“They are making him out to be the monster and he is not. The victim is my grandson,” she said, noting that she planned on getting him into counseling.

“He is a minor. She is old enough to know better.”

Earlier this week, Rockensies was charged with rape, criminal sexual act and acting in a manner injurious to a child less than 17 years old.

The charges included allegations that Rockensies exchanged sexual social media messages with the victim, and met with him for sex in her car.

If convicted, Rockensies, who has pleaded not guilty, could face up to seven years in prison. 

The sexual abuse charges ironically came after the teacher shared an infographic on Facebook in October 2021 explaining how to help “kids understand consent.”  

Rockensies’ husband, William, claimed that his wife is innocent despite prosecutors revealing disturbing details about her allegedly abusive relationship with the teen. 

“She’s been a big part of the community at her school,” he said.

“We all support her. We’re saying she’s innocent. I won’t elaborate any further why.”

Rockensies did not respond to messages left requesting comment.
