Doyle finished giving evidence in his defence yesterday, telling Crown prosecutor Harry Mallalieu he had never committed any of the crimes and that the three girls had colluded against him.
He said it was a case of them getting "vengeance" on him because they hated him.
He told Mr Mallalieu some of the allegations meant he would have to have had sex three times in one evening.
"I'm not that fit a person, no way in hell would that happen. I can't see anyone being able to accomplish that."
Doyle questioned why one of the complainants would accuse him of sexually offending against her, but then come and stay at his house several years later.
Mr Mallalieu asked why Doyle would allow the complainant to stay with him. "Weren't you concerned for yourself that you might have more false allegations made against you?"
Doyle said he felt safe having the complainant stay because he had his son in the house and was "a forgiving person".
Mr Mallalieu and the defence will deliver closing addresses to the jury today and Judge Thomas Ingram will sum up the case.
The jury are expected to begin deliberating either this afternoon or tomorrow morning.
