The men, two of whom are brothers, deny more than 50 charges.
They have faced claims that they attended drinking parties where a young girl was forced to sit naked and then raped.
The allegations - which date back to the 1990s - have been made by the daughter and son of one of the defendants.
A jury at Coleraine Courthouse on Thursday heard the two accused brothers giving evidence.
The father of the alleged victims told the court he was numb with shock when he first learned his daughter had made child abuse allegations against him.
"They're untrue," he said. "I have never, ever, ever harmed my children. Not even smacking."
When asked about drinking parties at his home he said he was "a party animal", but he denied that his children had been present at these events. His elder brother also denied raping the girl, and denied attending the parties where she was allegedly raped.
He told the jury: "It never happened. It's totally insane ... she is lying or mistaken. I have never in my life touched that wee girl."
The jury, though, has been told the two brothers recently pleaded guilty to a string of sex offences against their own sister - beginning when she was just four years old.
One of the brothers told the jury that he'd been drinking when he abused his sister, but he claimed that in 1997 he confessed the abuse to his parents.
The trial continues.
