Vinayak Rama and Reynold Carvalho have been jailed for raping the girl in a forest area in Leicester on October 1 last year.
Rama has been sentenced to 10 years and six months after admitting two counts of rape and Carvalho has been jailed for eight years and three months after pleading guilty to one offence of rape, the Leicester Mercury reported.
Rama, who was a passenger in a car driven by Carvalho, persuaded the victim to get in the vehicle and raped her in a secluded wooded area.
During the court proceedings, the defendants said they did not know the girl was below the age of consent as the victim told them she was 17, the report said.
The prosecution contended that the girl did not consent but was compliant to what happened.
