Arona claimed there was a threesome with the woman and the acts were consensual.
During her closing address yesterday, Crown prosecutor Anna Pollett said the two men "helped themselves" and took advantage of an incapacitated woman.
Contrary to evidence by Arona and Chambers, the complainant's statements to a doctor and police and the evidence she gave in court were entirely consistent, Ms Pollett said.
Ms Pollett said the complainant remembered she was not in a fit state to give consent.
"She certainly wasn't able to perform the type of sexual acts the defendants would like you to believe," she told the jury.
Ms Pollett said the complainant did not try to embellish or add to her original prior consistent statements.
The defendants' evidence was inconsistent, particularly when compared to text messages and phone calls between them and what they told the complainant, she said.
Ms Pollett said the defendants knew they were in trouble and have tried to rebut the allegations by attacking the woman's credibility.
"That includes calling her a groupie, a liar, a crazy, evil woman who was out to get them and bring them down, she said.
Ms Pollett said there was "no setup, no axe to grind" as the two defendants had tried to suggest during their evidence.
Chambers, who had given evidence over the past two days, repeatedly denied he was involved in a threesome despite Arona's evidence to the contrary.
He claimed the woman was being " flirty" and indicated she was "up for" having sex with him and for some reason has made up false allegations.
"She was not incapacitated. She was not passed out, she was in control, and she knew exactly what was going on in that room...she's lying," he said.
Ms Pollett put it to Chambers that in one phone call Arona told Chambers to say to the complainant she took off her clothes and they just helped her, and he did so.
Chambers insisted he never took off the woman's clothes and she was in control throughout their sexual encounter.
Despite telling the complainant he was wasted and could not remember much about that night, Chambers told the jury he was "tipsy" and tired but coherent and had total recall of what happened.
The two defence lawyers will give their closing statements to the jury today, followed by Judge David Cameron's summing up and the jury will then retire to consider its verdict.
