The District Court in Perth has been told the former partner of bikie Troy Mercanti is an exhibitionist who got into fights with other women over him.
Mercanti, a member of the Finks Motorcycle Club, is on trial, accused of assaulting Tammy Kingdon on five occasions between 1997 and 2012.
Mercanti's lawyer Colin Lovitt suggested to Ms Kingdon today that she loved to get naked in public and was delighted to be sleeping with a bikie when she met him at age 19.
Ms Kingdon broke down in court as Mr Lovitt then showed the jury pictures of her during her early 20s, when she worked as a stripper and dancer.
Yesterday, Ms Kindon described to the court how Mercanti punched her so hard a tooth fell out during a Christmas party in 2006 at his parents' house.
She testified that Mercanti's brother picked up the tooth and drove her to hospital, where she told doctors she had fallen down the stairs.
Ms Kingdon broke down in court as she described how her former partner forced her to stand in her front garden naked.
She said on one occasion in October 2011, Mercanti punched and kicked her in the couple's home before dragging her outside naked.
She said he later made her sit on a dog bed with a bone in her mouth, before attacking her again when she refused to bark.
It is alleged she suffered fractured ribs in the incident.
Mercanti has pleaded not guilty to the charges.
His defence team will argue Kingdon lied about the abuse to gain custody of the couple's two children.
The trial continues.
