A court heard that a child sex ring member abused two vulnerable female students "on a large scale.
A girl who was then 12 or 13 years old claimed that she was abused in Aylesbury, gham County and passed between 60 men who had sex with her.
The 11 men on trial in Old Bailey denied to varying degrees 47 sexual assaults between 2006 and 2012.
Prosecutor Oliver Saxby said the girls were used to believing that their "terrible" torture was normal.
Both of them come from a turbulent background, and when they are taken in by men, they all want to feel like they are growing up.
The allegations include multiple rape of children under the age of 13, child prostitution and "Stuttering" of girls for sexual purposes ".
In general, 45 allegations involved A child, which could not be determined due to legal reasons, were referred to as "A", and four other allegations involved A second girl, referred to as "B ".
Mr. Saxby said: "This case involves large-scale sexual exploitation of children.
It is characterized by two young girls. . .
Sexual abuse began at the age of 12 or 13.
"Both girls have unstable backgrounds and are perfect targets.
"Their lives are 'Off track '.
They are looking for places to get excited, pay attention, stay away from school and family.
"They want to feel like they are grown up and taken care.
For a group of men who want casual gratification that is easy, normal and easy to get, they can easily become prey.
The girls are good friends and they get gifts like alcohol, dvd, food and occasionally drugs, says Saxby.
"They are children. They say these men are their boyfriends.
They were passed from one person to another.
Sometimes every day.
"You may agree that its scale is terrible.
It is estimated that she has had sex with about 60 men . "
Eleven people in the trial were accused of being one of the men who abused female students.
At that time they lived in ellesbury, where alleged abuse occurred, some of whom were friends.
The trial continues.
