Eleven men have gone on trial accused of sexually exploiting underage girls who had been plied with drugs and alcohol.
The five youngsters - aged between 13 and 15 when the alleged abuse began - are said to have been "passed around" among a group of men in Rochdale and sometimes subjected to threats and violence.
A jury at Liverpool Crown Court has been told that one of the girls became pregnant at the age of 13 and had to have an abortion.
Another, who had absconded from a council care home, said she was sexually exploited by large numbers of men and given "substantial amounts of alcohol such that she was severely drunk when she was used for sex".
She said: "They just get you proper hammered so that you can’t do anything."
She claimed that she would regularly find herself drunk to near unconsciousness, waking up with men having sex with her.
The court was told that the case followed an investigation by Greater Manchester Police, with the first arrest in 2008 and the final one last year.
The jury heard police missed an opportunity to intervene earlier when one of the alleged victims disclosed what had happened but officers decided at that stage not to take the matter further.
The defendants are Kabeer Hassan (25), Abdul Aziz (41), Abdul Rauf (43), Mohammed Sajid (35), Adil Khan (42), Abdul Qayyum (43), Mohammed Amin (44), Qamar Shazad (29), Liaquat Shah (41) and Hamid Safi (22).
Another defendant cannot be named for legal reasons. All deny the charges against them.
Many other men, who have not been identified by the police, are said to have been involved in the exploitation.
