An ACT university student allegedly raped by a fellow resident at an on-campus dormitory had a casual sexual relationship with the man in the weeks after, a trial has heard.
The woman said she entered the relationship because she thought she could stay in control and make it normal.
Her accused attacker is on trial in the ACT Supreme Court on charges of sexual intercourse without consent.
The 23-year-old man has pleaded not guilty.
His trial opened before Justice John Burns on Monday.
The Crown – led by Trent Hickey – alleges the man raped the woman in his room on campus in 2011.
The court heard the pair had been on a pub crawl when they kissed on the dance floor of a Civic club.
They then caught a taxi back to the Australian National University dormitory, where the man allegedly lured the woman to his room with the offer of a cup of tea.
The woman told jurors she had accepted as, since they had kissed, she thought it would be nice to get to know him.
The pair kissed and the defendant allegedly attempted to touch her genitals several times, but she pushed his hand away and said "No".
THe man then allegedly pushed her down, took off her pants, and digitally penetrated and raped her.
"I kept saying no. I couldn't believe it. I didn't know what to do," the woman said from the witness box.
"I just lay there. I was just thinking 'Why is this happening to me?'."
She then went back to her room via the back stairs so she would not be seen and went to bed, she said.
The woman told the court that she had a friend drive her to a Belconnen chemist the following day to get the morning after contraceptive pill.
But she did not tell anyone about the alleged attack until she reported it to dormitory authorities in 2012 and then the police the following year.
"I really wanted to [tell someone], but just couldn't," she said.
The jury was told that the man contacted the woman soon after the alleged incident to ask how she was, and she told him everything was fine.
She then organised to meet him after a mutual friend mentioned the defendant had told friends they had had sex.
"I just thought if I saw him I could tell him to stop telling people," she told jurors.
The woman said she met him in his room, where he reassured her he would tell nobody.
They chatted, he kissed her, and they had sex again, the court heard.
The woman told the court they had sex a further three or four times before a holiday break.
"I was so shocked it happened to me and I just wanted it to go away," she said.
"I just really wanted to make it normal. I thought if I had control over it then it would be ok.
"I know I could never have a relationship with him because it was disgusting to think about."
The court was told the woman then met someone else over the holidays and broke it off with the man when university resumed.
Her evidence will continue on Tuesday.
Earlier in the day, in opening submissions, Mr Hickey told jurors that the woman had continued the relationship with the man as she did not want to be a victim.
But defence barrister, James Lawton, argued that the pair had consensual sex on all occasions.
Mr Lawton indicated that his client would give evidence once the prosecution case had closed.
The trial will continue before Justice Burns on Tuesday.
