A British teaching assistant groomed a 15-year-old student by taking her home to see her sex toys and handcuffs — before getting caught when another teacher saw them at a Pizza Hut.

A jury took just two hours to find Melanie Rock, 34, guilty of sexual grooming and sexual activity with a child by a person in a position of trust, the Telegraph reported.

Rock was a communications support assistant at Medina College on the Isle of Wight when she started chatting on Instagram with the boy, who’d been kicked out of class for his bad behavior.

They then met several times — with the teacher giving him around $60 before taking him back to her home.

There, she invited him to “enjoy her room” — and directed him toward a drawer with handcuffs, black see-through lingerie and sex toys, the boy told investigators in an interview played to the jury.

He described being uncomfortable as the teaching assistant gave him a “koala hug” after inviting him to lie on her bed to vape.

In other get-togethers, Rock bought the teen disposable vapes and clothing worth almost $500 from Trapstar, a London-based streetwear company.

They were finally caught out when they went to a Pizza Hut together, where another Medina College teacher saw them.

“We need to make something up, because if he sees us I’m going to lose my job,” Rock told the boy in a panic — then lying to her colleague that the teen was her godson.

The other teacher did not buy it and reported Rock to school officials, who questioned Rock about the relationship.

“F—k, I’m f—ked, I’m going to be sacked now they found out,” she texted the boy afterwards, and begged him never to mention her name.

Rock was taken into custody by police at the school two days later, and told cops that she had met the boy by chance and took him to Pizza Hut because he was hungry. 

Rock told the court during her trial that she continued to meet with the boy outside of school because she was worried about him.

“I’m a [mom], I care, I care too much, I was trying to keep an eye on him,” she said.

She claimed that she never acted sexually towards the boy and denied they ever had physical contact in her bedroom.

The jury deliberated for just under two hours before convicting Rock of sexual grooming and sexual activity with a child by a person in a position of trust. She is scheduled to be sentenced in December.
