A golf coach dubbed the "King of the Kids" told a child that kissing him would help improve her game, a Brisbane court has heard.
Sean Patrick Lynch, 68, is accused of grooming a 12-year-old girl before engaging in multiple indecent acts with the "gifted" junior golfer over a period of 20 months.
A District Court jury was played audio of a 2019 phone conversation between the girl and a man identified as Lynch recorded by Queensland police.
In the phone call the girl asked the man whether he could remember an alleged indecent incident.
"We didn't go too far with that. I was weak ... all that's happened, can we just forget all that stuff," the man identified as Lynch said in the recording.
The girl responded: "But I can't."
"Little did Mr Lynch know that (the girl) was at a police station and that call was recorded," crown prosecutor Chris Cook told the court.
Lynch groomed the girl then indecently treated her at his house and around golf tournaments in Queensland and NSW from April 2017 until December 2019, Mr Cook said.
The girl was aged between 12 and 15 at the time.
Lynch had worked as a peak performance golf coach and a sports psychologist, earning a reputation as a junior mentor, Mr Cook said.
"Because he helped a lot of younger children (he was referred to) as the King of the Kids," he said.
The girl - who once aspired to become a professional golfer - first met Lynch who ran a high performance academy in late 2016, the court heard.
"From around Easter 2017 Mr Lynch commenced sexualising (the girl), gaining her trust, grooming her," Mr Cook said.
The grooming "escalated" and they began exchanging text messages and having phone conversations that the girl later described as "smut", the court heard.
She would at times stay at his home with his family at his spare room downstairs.
Mr Cook said during one of her stays Lynch started kissing her, "telling her that he was happy for it to stop but that it would help her golf so much".
He also inappropriately touched her and asked her to send indecent pictures of herself on the phone, Mr Cook said.
Once she turned 14, Lynch showed her pornography "quite a lot" when they were alone at his house.
After she went to the police in 2019, the girl said in a conversation with Lynch he told her "she was the one who wanted all that to happen and that he was just trying to help her", the jury heard.
Lynch has pleaded not guilty to 11 charges including indecent treatment of a child under 16, possessing child exploitation material and grooming.
The trial before Judge Vicki Loury continues.
