Two Telford brothers convicted of sex offences against girls have been jailed for 18 and 14 years.
Ahdel Ali, 24, and Mubarek Ali, 29, both of Regent Street, Wellington, were also convicted of controlling child prostitution and trafficking girls.
The younger brother, who was given 18 years at Worcester Crown Court, was convicted of raping a girl of 13.
Stafford Crown Court heard offences took place in the Telford area between March 2008 and December 2009.
The jury heard the brothers had sexually abused, trafficked, prostituted or tried to prostitute four Telford teenagers.
Ahdel Ali was found guilty of one charge of rape, 11 charges of sexual activity with a child, three charges of controlling child prostitution, one of inciting child prostitution, an allegation of inciting a child to engage in sexual activity and meeting a child after grooming.
He was cleared on one charge of inciting child prostitution.
Mubarek Ali was convicted of four charges of controlling child prostitution, two of trafficking in the UK for sexual exploitation and a charge of causing child prostitution.
Judge Patrick Thomas QC said the brothers' motives were "squalid, demeaning and selfish".
He said the brothers were both "cold hearted and cynical" and "present significant danger to the public" and told them that they had shown "no remorse or regret".
Tayyab Khan, defending Ahdel Ali, urged the judge to be lenient because "this type of rape is not like other horrible types of rapes".
Mr Khan told the court that the 13-year-old girl said in evidence that she had not been forced to do anything, had loved him and she described him in court as a "pleasant person".
The judge interjected, saying: "I'm sorry Mr Khan, he's been convicted of rape."
Mr Khan said the girl told the court during the trial it had been a consensual relationship.
Speaking after sentenced, Det Ch Insp Neil Jamieson, senior investigating officer for West Mercia Police, said: "Ahdel Ali and Mubarek Ali targeted these girls because of their vulnerability and then systematically groomed them in such a way that eventually they could exploit them sexually for their own gain and gratification.
"This trial has been an ordeal for those giving evidence and I would like to pay tribute to the strength and character shown by all of the victims who came and gave evidence."
