The men deny 51 counts including rape, arranging child prostitution and trafficking a child within the UK for the purpose of sexual exploitation.
The charges relate to girls aged between 11 and 15 and cover a period from 2004 to 2012.
'Want to be loved' Jurors at the Old Bailey were told the girl, who cannot be identified for legal reasons, met three of defendants Kamar Jamil, Anjum Dogar and his brother Akhtar Dogar, while she was living at a children's home aged 14.
The court heard she drank and took drugs "to the point of passing out because she knew what was expected of her".
Noel Lucas QC, prosecuting, said the teenager felt she had to do what she was told by the men, otherwise they would threaten her and get rough with her.
It is claimed she was taken to alleyways, woods and various houses and flats where men would have sex with her.
Mr Lucas also told the court the girl had said to a friend: "I have no choice, I just want to be loved. I've never been loved and this shows me love."
The court has previously heard the group of men deliberately targeted vulnerable young girls with troubled upbringings which made it less likely anyone would be looking out for them.
The trial is expected to last until April. The defendants are all in custody.
The defendants are:
- Kamar Jamil, 27, of Aldwych Road, Oxford
- Akhtar Dogar, 32, of Tawney Street, Oxford; and his brother Anjum Dogar, 30, of Tawney Street, Oxford
- Assad Hussain, 32, of Ashurst Way, Oxford
- Mohammed Karrar, 38, of Kames Close, Oxford; and his brother Bassam Karrar, 33, of Hundred Acres Close, Oxford
- Mohammed Hussain, 24, of Horspath Road, Oxford
- Zeeshan Ahmed, 27, of Palmer Road, Oxford
- Bilal Ahmed, 26, of Suffolk Road, Maidenhead
