A father and son 'raped an eight-year-old girl together', a court was told.
David Brennan, aged 55, and Sam Brennan, aged 22, both from London, are accused of a combined total of 32 counts of child sex offences.
Woolwich Crown Court heard that they also made another victim, aged nine, wear the father's wife's underwear.
The pair, both from Eltham Hill in Greenwich, deny jointly raping an eight-year-old girl and a nine-year-old girl between 2003 and 2005.
David Brennan has pleaded guilty to some of the charges, including raping a child under 18, five counts of indecent assault on a girl under 18, one count of indecency with a child, and two counts of inciting a child to engage in and watch sexual activity.
However, he denies 18 other sexual offences, among them seven counts of raping a child.
His son Sam also stands accused of taking indecent photos of a child, one of indecency with a child, and one of engaging with a child in non-penetrative sex. He denies all the charges against him.
The trial continues.
