A man accused of killing the husband of his former lover has denied the affair ever occurred, a court has heard.
Bradley Scott Purkiss is jointly accused with Margaret Anne Otto for the 2017 murder of Ms Otto's husband, Risdon Vale tattooist Dwayne Robert Davies.
Both accused have pleaded not guilty.
Mr Davies was last seen by Mr Purkiss on May 26, 2017, and his body was found a week later at Levendale.
Taking to the witness box on Monday, Mr Purkiss told the Hobart Supreme Court he and Ms Otto were only ever friends.
Mr Purkiss said their relationship was never of a physical sexual nature and he had no intention to pursue this with Ms Otto.
"She was just my friend's wife," Mr Purkiss said.
"I would talk to her like I'm talking to you now."
Earlier in the trial, the court was played a video of Ms Otto's interview with police where she admitted to having an affair with Mr Purkiss, which concluded the year before Mr Davies' death.
Mr Purkiss said Ms Otto had "tried to crack on" to him on one occasion but he had turned her down.
The accused said he had received sexually explicit images of Ms Otto sent from her phone.
"I'd actually received photos [of Ms Otto] from Ms Otto and Dwayne himself," Mr Purkiss said.
Mr Purkiss said he was not aware of what was going on within Ms Otto and Mr Davies' marriage.
"I didn't know how Doc [Mr Davies] was treating Marg," he said.
"It's none of my concern how he treated his family."
Mr Purkiss denied downplaying his knowledge of Ms Otto and her relationship with her husband.

Earlier in his evidence, Mr Purkiss said it was Mr Davies who had arranged for three men to bring two motorcycles to Elderslie for the pair to look at on May 26.
Crown prosecutor Allison Shand said this account differed from what Mr Purkiss told police in 2017.
"The first time we hear of any of this is during your evidence today," Ms Shand said.
Ms Shand suggested to Mr Purkiss he made up these events to fit the evidence of the trial, which Mr Purkiss denied.
The court heard Ms Otto told police on the night Mr Davies disappeared Mr Purkiss came to her home at 11pm.
She said he pulled out the CCTV box, told her she was "free", took an empty shotgun shell with the number six on it and put it down on the bench and threw a bracelet belonging to Mr Davies into the fire.
Mr Purkiss denied going to Ms Otto's house that night.
Victim and accused 'best mates'
Mr Purkiss told the court he first met Mr Davies in 2011, when he got a tattoo done by him, and the pair became friends in 2014.
"We became close friends," he said and told the court he considered Mr Davies to be his best mate.
Mr Purkiss said he and Mr Davies shared a number of interests including tattooing, smoking cannabis, collecting things and tinkering in their sheds.
The court heard Mr Davies had owed Mr Purkiss $17,800, including $5000 for renovating the tattoo shop and $9000 for renovating his Risdon Vale home.
Mr Purkiss said this debt had been mostly "squared away" aside from Mr Davies needing to paint the kitchen at his Elderslie home.
He said Mr Davies was going to pay off the debt by giving him two motorcycles, both of which did not belong to Mr Davies, and other small items.
"I don't like money very much," Mr Purkiss said.
When asked by his lawyer Alan Hensley if he murdered Mr Davies, Mr Purkiss said "no I did not".
Mr Purkiss also denied Ms Otto had asked him to carry out the murder.
"I would have informed my mate if his wife had made a comment of those words," he said.
The trial before Chief Justice Alan Blow continues.
