The 17-year-old later told her mother the pair “grabbed her, took her pants down and took turns raping her”.

Mitchell Bowran is on trial on five counts of rape and Charlie Star on three counts of rape following the incident on the night of September 2, 2017.

Both have pleaded not guilty, with their lawyers arguing the trio had consensual sex.

The Wodonga County Court on Wednesday heard the alleged victim, aged 17 at the time, repeatedly told the pair to stop.

She said she “had never had sex before”, with Star allegedly then saying “well that’s going to change tonight”.

Prosecutor Peter Triandos said the pair had asked the teen to go behind a shed during the 18th birthday party after Bowran kissed her.

Bowran allegedly touched her before she said “I don’t want to do this anymore”.

Her belt was allegedly unbuckled and her clothes and bra removed, before her breasts were touched. 

Star allegedly digitally penetrated her before raping her without warning and putting his penis in her mouth.

Bowran allegedly began raping her, causing her to scream in pain, and causing him to laugh.

The pair allegedly continued to take turns raping her.

“She tried to scream but it was muffled because she was having trouble breathing,” the prosecutor said.

“Mitchell and Charlie were laughing ... she said stop, I don’t want to do this."

“Mitchell said come on, yes you do.”

The 17-year-old vomited during the incident, Mr Triandos said.

Bowran had allegedly forced his penis into her mouth by pushing her head down and wouldn't let her move, causing her to choke. 

The court heard the girl sat on the ground in shock for about five minutes after the incident and was distraught when found by a friend.

"She didn't know what to do," Mr Triandos said. 

"She began shaking. 

"Her pants were still down and her shirt was open."

IN OTHER NEWS:

She was picked up by a friend’s mother and went to the Wodonga Police Station.

Officers returned to the property on the morning of September 3, took photos of the scene and spoke to other partygoers.

The alleged victim was examined by a doctor the same morning and said she had been sexually assaulted. 

She had bruising to the front of her upper left abdomen, three abrasions on the front of her abdomen and cuts to the front of her left leg. 

The men told police it was a consensual encounter and the girl a willing participant who had instigated the acts. 

Bowran’s lawyer Hayden Rattray said the case was about consent, young people, alcohol, bad choices and regret.

“The defence case is that what happened behind the shed was entirely consensual,” he said.

The trial will continue on Thursday.
