The father threatened to throw his partner out on the streets if she refused to have s*x with their son, a court heard.
The son, who is now 12, claims his father forced his mother to have s*x with him from the age of six. The man also allegedly r*ped his son, sexually abused him with a red hot poker and held a machine gun to his head after watching a James Bond film, it has been claimed.
The father is alleged to have filmed some of these incidents and shown them to others.
He is further alleged to have left his son locked in a box at their home in County Waterford in Ireland after he watched a film about a gorilla in a cage.
The boy’s parents face a total of 82 charges of abuse between 2007 and 2011, the Irish Times reported.
The father and mother have pleaded not guilty to 16 counts each of sexual exploitation and one charge each of child cruelty.
The mother has also denied 16 counts of sexual assault while the father denies 16 counts of rape and 16 counts of sexual assault with a poker.
Yesterday during the trial at the Central Criminal Court in Dublin, the boy told his father’s barrister, Colman Cody, that he loved his mother.
The boy, who was taken into care aged eight, said his mother only raped him “because she didn’t want to go homeless”.
But in previous statements the boy had said his mother was happy to have s*x with him and threatened to kill him if he didn’t comply, Mr Cody said.
The barrister also accused the boy of being bribed by his foster mother who allegedly gave him sweets and treats whenever he repeated allegations about his father.
The boy said his father owned “50 guns and 50 bullets”, which included a rocket launcher, an AK47, an Uzi sub-machine gun, “a sniper”, “a gun you can put a silencer on”, and a Beretta, “like you would see in Dr No in James Bond”.
He said his father also owned an 18th-century ceremonial sword and several knives.
