Alleged sister rapist: 'She wanted to practise having sex'

A FRASER Coast man is accused of getting his little sister drunk and stoned, repeatedly raping her and giving her money to buy the morning after pill hours after one of the assaults.

The 37-year-old man cannot be identified for legal reasons, but his trial is under way in Brisbane Supreme Court.

The Coast businessman has pleaded not guilty to three charges of rape, two of indecent treatment of children and one of supplying a drug to a minor.

The alleged victims are his younger half-sisters and the offences are said to have occurred in Brisbane and Hervey Bay between 1998 and 2006.

The girls were eight and six years old respectively and their brother was aged around 16 when the alleged offending began.

Crown prosecutor Mal Harrison told the jury on Monday the first charge of rape related to an incident in 1998 when the family was living in Brisbane.

The man is accused of entering his little sisters' bedroom and lifting the eldest girl from her bed.

He took her into his room and laid her down before removing her underwear and spooning her, Mr Harrison said in his opening address to the court.

The girl - now aged around 29 - says he then raped her.

Afterwards, he told her not to tell her mother and father and that if she did her parents would disown her and they would kick her out.

The alleged indecent treatment stems from an incident sometime between 1999 and 2002 when the defendant is accused of holding both girls on his lap and kissing them sexually.

Mr Harrison said the final set of offences - two rapes and the supply of drugs - allegedly took place in Hervey Bay in the man's unit and while his housemate was at home.

The victim was 14 years old at the time and was visiting her brother's home to attend a going away party he was holding.

Mr Harrison said the girl had never used drugs until that day, when her brother is accused of giving her marijuana in a bong.

It is also alleged he gave her alcohol.

"It was her first time using drugs and she recalls feeling slow and lazy and laughing at things she wouldn't normally laugh at," Mr Harrison said.

The girl did not remember much after that.

She woke up the next morning dressed only in a T-shirt and her brother lying next to her in his bedroom.

Mr Harrison said her brother asked her to perform a sex act on him, which she refused so the man started masturbating before he allegedly raped her orally.

"She felt like she had no choice," Mr Harrison said.

Mr Harrison said the girl did not recall being assaulted during the night but that she suffered extreme soreness in her genital area and also in her stomach the morning after the party.

Before she left, the brother is alleged to have given the girl $20 and told her to go and buy the morning after pill.

It is also alleged that he spoke to a family member and "made certain disclosures" and that he said "he had done something stupid", Mr Harrison told the jury.

The brother also told the family member the victim was to blame for the alleged assault, saying "she said she wanted to try new things and practise having sex".

The brother's sisters will give evidence over the coming days, as will the man who lived in the house where the last two alleged rapes are said to have occurred.

The trial before Justice James Douglas continues. - NewsRegional
