The accused's mother said she was home when the woman, aged 18 at the time, arrived to see her son on the night of the alleged offending.
Soon after she went to bed, leaving her door open, and the pair then went into her son's bedroom next to hers to watch a film, she said.
Over the next one or two hours she heard them talking and laughing through the wall, she said.
The man's mother then went to get a drink of water and seeing her son's TV still on, she walked into his room. He was sitting on the bed fully clothed and told her the woman had left, said his mother.
"She'd made a move on him. He'd asked her to leave," she told the court.
The young woman told the court yesterday that although they had earlier had consensual sex, her feelings for him changed and on September 25 she made it clear she did not want anything sexual to happen between them.
Once they got into bed, however, he became sexual towards her and his advances escalated in spite of her resistance, she said.
The man maintained no sexual contact took place, said his lawyer Todd Simmonds, who suggested the woman made up the allegations of violation and indecent assault because he had rejected her advances.
'You felt jilted, you felt rejected, you felt angry and you've pointed the finger at this young man," Mr Simmonds told her.
The trial continues.
