Peterborough restaurant owner Mohammed Khubaib, 43, was convicted of rape and grooming offences last month.
During his trial at the Old Bailey, the jury was told he forced a 14-year-old girl to perform a sex act on him after getting her drunk.
He had a "persistent and almost predatory interest" in girls, the court heard.
Det Supt Gary Ridgway from Cambridgeshire Police said the sentence showed "just how serious this type of offence is".
"This represents justice for young people who had the courage to stand up in court and relive some very difficult experiences," he said.
Khubaib was the tenth person to be convicted under Operation Erle, which focussed on allegations of sex abuse by other groups of men and boys against young girls.
Four previous cases led to nine male defendants being jailed for 59 offences against 15 girls from Peterborough and elsewhere in the East Midlands.
"We are pleased with this sentence today as it represents justice for the girls and young women who suffered at the hands of this vicious criminal," said Wendi Ogle-Welbourn, from Peterborough City Council.
She praised the "bravery" of the victims who had given evidence during the course of the trial.
"Their courage in reliving some absolutely horrendous experiences at the hands of this criminal has enabled us to get the result we did today and means that other girls and young women are safer in our city," she said.
Cambridgeshire's Police and Crime Commissioner Sir Graham Bright described Khubaib's actions as "crime of the worst kind".

The £200 "monocular", which has a built-in laser illuminator to improve viewing in the dark, will be used by Stafford Borough Council inspectors.
During winter months it is more difficult to catch irresponsible dog owners, the council said.
Staff members who use the monocular will be uniformed and wear a badge, a spokesman added.

"The only people who should be worried (about this) are the inconsiderate dog owners who are not clearing up after their dogs," a spokesman said.
Previous council schemes have involved people ringing a phone line to highlight the worst-hit areas.
Staff are already targeting these "hotspots", the council said, but have found it difficult since the clocks went back.
Councillor Frank Finlay, cabinet member for environment and health, said the council had tremendous support from the community to get rid of this "disgusting crime".
"These night-vision goggles will help us overcome this problem and let people know that, even under the cover of darkness, they cannot get away with showing blatant disregard to their fellow citizens," he said.
A businessman who plied teenage girls with vodka before sexually abusing them has been sentenced to 13 years.
