A ROCKHAMPTON man charged for allegedly sexually assaulting his teenage step-daughter was "tyring to help him understand her", day one of a trial in Rockhampton District Court heard today.
The man, who was 39-years-old at the time of the alleged offending, previously pleaded not guilty to one count of common assault, two counts of rape and three counts of sexual assault.
Crown prosecutor Ryder Reid told the court the trial was "about consent" and the complainant was "afraid of (the defendant) as he would become violent if she did not comply".
He said the defendant was a "controlling male figure in the family environment".
Mr Reid said the charges related to the defendant allegedly performing sexual acts in front of the girl, asking her to help him perform a sexual act and making her perform a sexual act on herself.
Mr Reid said the defendant "began showing sexual interest" in her and showering with her after an incident in the car in which he lost his temper and punched her in the arm and leg.
Mr Reid said when the complainant told the defendant to stop he said she "should become more comfortable with herself".
The court heard the man admitted in an interview with police he had sexual relations with the girl but said it was consensual and the girl "said she was desperate to have sex" and "that's when things got weird".
The trial, which is expected to finish on Thursday, continues tomorrow.
