A female doctor is accused of killing her husband with a hammer after they engaged in a threesome with a teenage girl.
Chamari Liyanage is alleged to have murdered Dinendra Athukorala over fears their sexual activity could burden her career.
The Sri Lankan couple had threesomes with a number of other women, including a 17-year-old girl.
Liyanage is on trial charged with killing her spouse, also a doctor, with his own hammer.
When police arrived, the walls were splattered with his blood and she was curled up beside the bed, it is alleged.
The jury at the Supreme Court of Western Australia heard how the defendant was at breaking point and had become fed up of her "controlling" husband.
She had told police how he was physically violent, forced her to engage in sexual acts and controlled her finances and kept tabs on where she went.
