A jury has retired to consider its verdict in the case of a 71-year-old masseur accused of sexually assaulting 15 women - including a police officer - and a 15-year-old girl over more than a decade.
Charles William Davidson is facing trial on seven counts of rape, 32 counts of sexual assault and three counts of indecent treatment of a child under 16.
The Crown alleges Davidson touched the alleged victims sexually during what was supposed to be a therapeutic massage.
The alleged behaviour - occurring between 2003 and 2015 - included tweaking and twisting of nipples, inappropriate touching of groin areas, as well as digital penetration.
"These all occurred under the guise that he was performing a legitimate massage upon them," prosecutor Judy Geary has told the Brisbane District Court trial.
The jury heard Davidson would often steer conversation toward sexual subjects, including telling a client his favourite style of massage was "erotic" or talking about their breasts.
Davidson's actions were exploitation by a person in a position of trust, Ms Geary told the court in her closing arguments.
Davidson first massaged clients informally at his house before establishing a home massage business and eventually working in physiotherapy and chiropractic clinics around Brisbane.
But Ms Geary said the women were expecting to have massages that had a therapeutic purpose.
"We are not talking about some sexual massage place," she added.
Ms Geary asked the jury to consider the "incredible similarities" in the descriptions each of the women gave about what happened.
But defence lawyer Simon Lewis said there were "little errors" in evidence heard during the trial.
He also told the jury police had obtained records of people who had received massages, calling them to ask if they had any concerns.
Something the women previously thought was a bit odd, or made them feel a bit uncomfortable, may have taken on a "sinister" tone when contacted by police, Mr Lewis added.
He told the jury it would "be nuts" for Davidson to inappropriately touch a woman "for no apparent reason" after being told she was a police officer.
Davidson faced a total of 34 sexual assault charges at the start of the trial, but two have since been dropped by the prosecution.
He did not give evidence or call any witnesses.
The jury retired on Thursday morning to consider its verdict after Judge Julie Dick summed up the evidence.
