Teenage girls were sexually exploited in Rotherham by older men because they were easy targets who "needed to be loved", a court heard.
Eight men are on trial accused of raping and sexually abusing eight teenage girls.
The men, aged between 33 and 39 and all from South Yorkshire, are charged with dozens of offences said to have taken place between 1998 and 2005.
All the men deny the charges at Sheffield Crown Court.
The jury was told how girls were "lured by the excitement of friendship with older Asian youths" but then sexually assaulted and passed between men.
Prosecutor Michelle Colborne QC told the court how the trial involves what allegedly happened to five girls, who are now women in their 30s, between 1998 and 2005.
She said: "When they were in their teens, they were targeted, sexualised and, in some instances, subjected to acts of a degrading and violent nature at the hands of these men who sit in the dock."
Ms Colborne said the girls had unsettled home lives and they "believed sex of some kind or other was a necessary price for friendship".
'Easy to exploit'
The prosecutor said that two of the complainants were sisters who were "effectively abandoned" by both their parents when they were very young.
She told the jury that the sisters "had already been corrupted" when they came to the attention of two of the defendants, Mohammed Imran Ali Akhtar and Tanweer Ali.
The previous exploitation had begun when one of them was as young as 11, she said.
The prosecutor said: "These sisters, like so many others, were easy to exploit because they needed to be loved."
