Yesterday, a video interview with one of the students was played to the court. She explained how the artist would lock the door to his studio before becoming physical.
"You need this experience, it will make you a better arts student," the woman said the man would tell her.
Defence counsel Phil Hamlin said his client categorically denies any touching was inappropriate or without consent.
He said the artist "believes honestly" that when there was a sexual relationship it was "obvious" it was consensual.
Today Hamlin cross-examined the first student via video link, questioning whether she was fabricating parts of her story.
"You didn't protest at all, did you?" he began, further asking why the teen left the private studio and walked into the main studio "as if everything was normal".
"Yes, because that's what he told me [to do]," the teen replied.
"He was gentle and friendly when he had sexual activities with you ... He never forced you to do anything at all, did he?" Hamlin continued.
"In a way he did," she replied.
Hamlin said the teen was looking back on the incidents with "different eyes", but at the time was "willing to participate".
"I was not," the student said, adding she had no choice because she was "scared" to tell her parents.
"I'm also threatened by him," she said.
"That's new," a seemingly surprised Hamlin replied. "Tell me about that."
"He would text me in the middle of the night and tell me I had to go to his classes otherwise I would fail," the student explained. "And he also said that he would ring my mum."
Hamlin asked the student if she was "making this up as you go along?"
"I'm not," she replied.
The defence lawyer continued his cross-examination by questioning why the student would ask the artist for help and wished to meet with him in his private studio if she felt threatened.
"It was completely consensual, wasn't it?" he said.
"No, like I said in the video there was no consent," she replied.
Hamlin said further evidence that the relationship was mutual was the student's attendance at exhibitions and her social media conversations with the artist.
The lawyer asked if the artist had a Facebook page that included several of his students, who would converse with each other.
The teen denied there was such a website, but later said the experienced teacher "would share his life with us".
Photos of social media messages between the artist and student were also presented to the court.
Hamlin said the student was often the one instigating the online conversations with the artist.
"At all times of the day and evening, weren't you?" he said.
"Not necessarily," she replied.
"You're having regular contact with him ... that's what we can see, can't we?" Hamlin continued.
"Yeah. It's based on what I'm working on in art," the teen said.
Hamlin added the messages also showed no evidence of the teen making excuses to go back to the art class, as she had indicated in her video interview.
The trial continues.
