A U.K. man who admitted to having sex with and abducting a 13-year-old girl after posing as a schoolboy will spend 30 months in jail.

James Chester, 22, befriended the girl's brother, became part of the family and was even seen by her mother in school uniform.

Chester had initially enrolled into a secondary school when he was 19 but was found out. He met the family from Portsmouth, England in early 2007 and began a sexual relationship with the girl.

Prosecutor Mary Johnson said Chester told the family he was 16 when he was really 21, the Portsmouth Crown Court heard.

The teenager, who was not identified, said she willingly had sex with Chester about 50 times.

"You knew you were entering into a sexual relationship as a young man of 21 with a girl of 13," Judge Graham White told Chester. "Not only did you deceive her, you also deceived her parents whose job it is to protect her."
