Dominatrix Heide Victoria Bos wanted her on-and-off-again boyfriend hurt badly enough that he'd leave town.
He ended up dead.
Nick Cameron suffered 14 blunt force head injuries and two stab wounds when he was attacked over 11 minutes in the parking garage of his Melbourne apartment on July 10 last year.
He had taken his fluffy white terrier, Misty, into the garage when a man, who had allegedly been laying in wait beside Mr Cameron's rental car for seven hours, rushed at him armed with a knife and a hammer.
Neighbours heard Mr Cameron's yells for help. Efforts were made to save him, but he was declared dead about 45 minutes after the attack began.
A man has been charged with murder and is due to face trial in the Victorian Supreme Court next year.
Bos was charged with murder within weeks after Mr Cameron's death, but pleaded guilty in November this year to manslaughter on the basis that she was complicit in an agreement for him to be assaulted.
She met the alleged killer six weeks earlier on a fetish website, where she used the name "Hedonistic Siren" to meet "slaves".
"I am above you in every single way possible," her profile said.
She and Mr Cameron had a volatile and verbally abusive relationship, prosecutors told a pre-sentence hearing on Wednesday.
In messages Bos described Mr Cameron as hurting her in unique and nasty ways and asked if it was possible to get him to leave town and not come back.
Bos accepts responsibility for Mr Cameron's death, her lawyer Rahmin de Krester said.
"She feels guilt and shame that he died because of her involvement with (another man)," he said.
Chris Cameron penned a poem about his relationship with his son, and described his skills as a footballer and a friend.
"By crikey, if your mateship was appreciated, a locked in warm-hearted friendship was given and it was lifelong," he said of the 39-year-old.
Mr Cameron's partner was expecting their first child when he died. She told the court that the second half of her pregnancy was surrounded by loss and even now with each milestone in their child's life overshadowed by grief.
Bos will be sentenced in February.
