A married school teacher allegedly told a teenage boy that he had a “bigger penis” than her husband in a string of dirty texts, a court has heard.

Kandice Barber, now 35, has denied having sex three times with the then 15-year-old student, including once in a local field.

The teacher is accused of claiming she was pregnant with his baby and sending the boy topless snapchat pictures.

The married mum has also been accused of sending the teenager a string of texts where she complimented him on his penis size.

And in another, the teacher said she wanted to play a game to see who could be “horniest” while she the pair were in class, a court heard.

Aylesbury Crown Court in Buckinghamshire heard that other students had been shocked at seeing Barber’s nude pictures.

One schoolboy, who cannot be named for legal reasons, told a jury on Thursday: “I was shocked that it even had started. I thought it was something that only happened in the newspapers.”

The student said he was told that Barber had sex with her alleged lover and that she told him she was on the pill, so he did not wear a condom, the court heard.

The court heard evidence from one of the boy’s close friends who was allegedly with him the first time he contacted the then 33-year-old teacher online.

The court heard he said he saw a message on his friends phone, from Barber, asking: “Do you prefer boobs or bum?”

The message had been sent at a sports event where the pair are said to have swapped Snapchat details.

Snapchat is where the two communicated, the court was told.

The witness said that Barber had told her 15-year-old student that she had “had a dream about [him]” before exchanging details on his phone.

The schoolboy witness said: “Next morning, he showed me messages of her sending him messages including ‘morning’, and stuff like that. He seemed pretty chilled about it, as if it was like just another girl.

“One time, we were in English and she was teaching another class. She sent him a picture of her teaching."

The jury head that the two met up in October 2018, and had sex on their second meeting, as opposed to the first meeting as the complainant testified originally.

The witness said: “First I didn’t believe it at all, then I started seeing the videos and messages and all that, I was like 'yeah, it’s probably true.

“She told him she was on the pill and he didn’t wear a condom.

“The messages said that he (the complainant) had a bigger penis than her husband. In another message she told him 'when I’m teaching you, let’s see if we can make each other the horniest we can without the others knowing’.”

The court was told that the “video” referred to was a three-to-five second pre-recorded video which the defendant was said to have sent to her pupil on Snapchat while he was in class.

The jury was also told that the student had gone to see Barber in her office several times and left claiming they had been kissing.

In March 2019, during a police interview, another student claimed to have seen the pair go into her office and also spotted them talking in hallways.

He had not believed rumours of the pairs affair until he saw pictures.

Topless pictures sent to the student from Barber were allegedly spread throughout the school and eventually made their way to the headteacher, the court heard previously.

The witness said: “There was one time we were having lunch in the sports hall, when [the complainant] went outside to the closed off bit on the stairs. He came back and told us they had kissed and talked a bit.”

Barber, of Wendover, Bucks, denies three counts of causing or inciting a child aged under 16 years to engage in a sexual act.

She has also pleaded not guilty to one count of sexual communication with a child, one count of causing or inciting a child to engage in sexual activities while in a position of trust and one count of causing a child to watch a sexual act by a person in a position of trust.

The trial was adjourned until tomorrow.
