The girl, who felt threatened and intimidated, performed oral sex on five of the youths during her hours-long ordeal at two isolated toilet blocks and on a building rooftop in Sydney.
During one incident, she was told, "Just smile like you're enjoying it," while one youth later gave her his phone number and asked her to call him.
At times, youths yelled at their mates to "hurry up, it's taking too long" and "your turn's up".
Four of the teenagers, who were aged 15 and 16 at the time and cannot be named, faced a sentencing hearing in the NSW District Court on Thursday.
Three have pleaded guilty to one count of aggravated sexual intercourse with a girl under 14, and the fourth has admitted two such offences.
A fifth youth, referred to as KD, will be sentenced separately, a sixth is before the Children's Court, and no information was available on the seventh, who is referred to as "an unnamed male" in the agreed facts.
The offences took place in July 2007, at two different toilet blocks in Yagoona parks and later on the rooftop of a Bankstown building.
The facts said the girl agreed to meet KD at the Bankstown Bus Depot on that day, after having first met him days earlier at a shopping centre.
He arrived in full school uniform and, to her surprise, was accompanied by two other youths, one similarly dressed and the other in partial uniform.
The trio caught the train to Yagoona railway station, where the girl was led to a public female toilet block in a park, where four other males were seated outside.
Comments such as "you're hot" were made to her, before KD asked "would you give my friends head jobs?".
When she said no, he continued to question her, resulting in her feeling "threatened and intimidated" and saying "yeah whatever".
She went into a cubicle with one youth, with whom she had oral sex, after which another teenager said "I'm going to root her" before penetrating her and causing pain.
After they were disturbed by council workers, the girl was surrounded and walked to another toilet block in a nearby park where more oral sex took place, as well as digital penetration.
Later, at a building rooftop in Bankstown, another youth arrived and she was told to give him "a head job".
She said: "I don't want to. I've had enough. I've had to give everyone head jobs today.*"
She eventually complied "feeling angry that she was being forced to do something she didn't want to".
That evening, the girl was told video footage of her performing oral sex on one youth had been sent to another male.
In sentencing submissions, lawyers for the four referred to their immaturity, lack of sex education, good family backgrounds and contrition.
One of the four boys, who was only at the rooftop, had not known about what happened earlier and had "taken the opportunity" to engage in his first sexual encounter, Judge Richard Cogswell was told.
He adjourned submissions to February 20.
