Stag party stripper accused of raping best man

A buck's party stripper raped the best man with a sex toy before swinging a punch at him and threatening to call her bikie mates, a Melbourne court has heard.

Linda Naggs, 39, of Rosebud, is accused of sexually penetrating the man after she turned to him when the groom decided he did not want to be part of the show.

Naggs entered the party on Victoria's Mornington Peninsula in September last year cracking a whip and performed an act for the groom before moving on to the best man, a witness told Melbourne Magistrates Court today.

The alleged victim's brother said the best man had his top off and pants half down when Naggs began riding him like "a dog or a horse".

He said he heard his brother tell Naggs "don't put it in" before he squinted and jolted.

Naggs then became a "little bit hysterical" and onlookers were trying to calm her down when his brother became angry and told her to leave, he said.

Another witness said the alleged victim, who cannot be named, was cheered on by a crowd of up to 30 men.

The man appeared reluctant to take part and a naked Naggs forced him to his knees and "pulsated" him with the sex toy which she was wearing, he said.

Naggs wore a "cheeky smile" throughout the incident, but the alleged victim turned red in the face and screamed at her.

"He said: 'Why'd you do that for? You didn't have to do that'," the witness said.

The alleged victim pushed Naggs in the chest and she responded with a punch but missed, the witness said.

Party-goers intervened to keep the pair apart, he said.

The alleged victim's brother told the court Naggs threatened to call her "bikie mates".

He said that before the incident, onlookers had been cheering in a "mature way" and urging the alleged victim to "c'mon".

"It wasn't over the top rowdy or aggressive," he said.

He said his brother was "very conservative" but appeared to be happy and smiling before the incident.

Naggs - who was part of an entertainment line-up that included another stripper and topless waitresses - has been charged with one count of rape.

Her committal hearing before Magistrate Elizabeth Lambden continues.
