A police summary of facts said the man photographed the victim with his cellphone while she was naked after two of the three instances of intercourse.
After a complaint was made to police, the man was spoken to and said while he believed the sexual activity was consensual, he knew it was wrong.
A victim impact statement read in court by one of the victim's supporters described her as a confident woman who felt safe in her own home prior to the offending.
Afterwards, the victim ''cried every day'' and could not bring herself to visit her workplace to see friends which ''took its toll on an emotionally vulnerable young lady'', the statement said.
Judge Maze said there was a ''predatory nature'' to the man's offending.
She ordered final name suppression to protect the identity of the victim and the defendant's school-aged children, who she said would endure undue hardship if his name was made public.
