Bilal Hussain and Shazad Rehman are accused of repeatedly raping one girl and raping two other girls they picked up in the Keighley area.
Mr Hussain, 23, of Leeds and 30-year-old Mr Rehman, of no fixed address, pursued teenage girls between 2010 and 2011, Bradford Crown Court heard.
They have pleaded not guilty to nine rape charges and supplying cannabis.
Mr Rehman has also denied two charges of sexual assault which relate to one of the rape complainants and a fourth young girl.
The pair also deny a charge of conspiracy to pervert the course of justice.
‘Out of their depth’
Prosecutor Michelle Colborne QC told the court on Tuesday: ”They acted together travelling from their various home addresses in Leeds and Halifax to the Keighley town centre where they specifically targeted vulnerable girls, all underage.”
She said some of the girls, none of whom can be identified, had difficult backgrounds or were emotionally fragile and may have been seeking attention.
”They were out of their depth,” she told the jury.
”They were supplied with strong alcohol and cannabis, enticed to believe they would have fun, that they were special. In truth what was on offer was beyond their control.
After one of the girls told Mr Hussain she thought she was pregnant, he allegedly said she had to terminate the pregnancy or he would kill the baby himself.
Miss Colborne said Mr Rehman boasted to a woman they could get any girl they wanted and described them as ”fresh meat”
