A complainant has told a court Alan Jones made him feel "trapped" amid several alleged incidents where he was kissed or touched as a teenager.
The veteran broadcaster has pleaded not guilty to all charges in the indecent assault and sexual touching trial.
The trial, which began on Monday, is expected to last several weeks.
A man accusing Alan Jones of indecently assaulting him has detailed in court a night at the broadcaster's farm, where he said Mr Jones demanded he have a shower and come out wearing "a robe and nothing else".
Mr Jones, 85, is facing an indecent assault and sexual touching trial in the Sydney Local Court, which is hearing evidence from the first of six male complainants.
He has pleaded not guilty to all charges, and his defence lawyer told the court on Monday the case was actually about media rivalry and treachery from colleagues.
Complainant J began giving evidence on Monday that Mr Jones took an interest in his early sporting career, and gave him a phone, a car and weekly payments during a time where it is alleged the broadcaster kissed or touched him several times.
In court on Tuesday, Complainant J detailed a stay at Mr Jones's Fitzroy Falls farm in 2004, where he said he and the veteran broadcaster spoke over dinner and a glass of wine.
He said Mr Jones told him: "You've got to remember, there's only one rule here … there are no rules."
Mr Jones told the then-17-year-old to go and have a shower, the court heard.
"The defendant told me to go and have a shower and come back in a robe and nothing else," he said.
"It was, '[J], come back in a robe and nothing else.'"
The court heard Mr Jones told the complainant there were "no rules". (ABC News: Ethan Rix)
The man alleges he wore underwear under his robe, and said his "heart was racing" as he sat on the couch next to Mr Jones, who he alleges rubbed his genitals on the outside of his robe.
