A jury's heard how two ex-BBC radio presenters from Leicestershire had sex in public 'knowing and taking delight in the fact' that teenage boys were watching.
Julie and Tony Wadsworth both deny charges of outraging public decency and indecent assault on young boys.
The prosecution alleges the boys, who were around 14-years-old at the time, were encouraged to take part in sexual activity.
It's alleged the offences happened in the 90's at a park in Warwickshire.
Husband-and-wife Tony and Julie Wadsworth are alleged to have encouraged seven boys, including a teenager looking for a golf ball, to take part in sexual activity in wooded areas of Warwickshire between 1992 and 1996.
Julie Wadsworth, 60, and her 69-year-old husband, from Broughton Astley, Leicestershire, deny indecent assault and outraging public decency by having sex against a tree in full view of boys.
Opening the case against the couple, prosecutor Miranda Moore QC said they were known to the public as Wadsworth and Mayer (Julie's on-air surname) and had worked at the BBC's former studios at Pebble Mill, Birmingham.
Alleging that Mrs Wadsworth had engaged in numerous sex acts with boys in parkland while her husband acted as a look-out, Miss Moore told jurors the broadcaster had admitted engaging in "hanky panky" with him while outdoors.
Some of the couple's alleged victims claim Mrs Wadsworth was variously dressed in a "flasher's mac" trench coat, white high-heels, stockings, suspenders, and a split-skirt at the time of the offences near Atherstone.
Outlining the prosecution case at Warwick Crown Court, Miss Moore said:
Mr Wadsworth - who has presented shows with his wife on BBC Radio Leicester and Birmingham-based BBC WM - is alleged to be guilty of indecent assault in the same way that an intruder's look-out would be guilty of burglary.
Alleging that Mr Wadsworth acted as an early warning system for his partner, Miss Moore told the jury of seven men and five women:
On one occasion, the court heard, an alleged victim was "spooked" by Mr Wadsworth standing nearby with a camera around his neck. Jurors were told Mrs Wadsworth reacted to the boy's concerns by telling her husband to "go away for a walk" and proceeding to perform a sex act on the youngster.
The trial continues.
