A teaching assistant who had sex with two teenage pupils at the school where he worked has been jailed for two years and nine months.
Ryan Stewart, 26, developed relationships with the girls using social networking sites on the internet and through text messages while working as a maths coach at a South Yorkshire secondary school, Doncaster Crown Court heard.
Stewart admitted having sex with the 15-year-old and the 17-year-old, at a previous hearing.
He denied further offences involving two other girls, aged 14 and 15, but these were ordered to lie on file by a judge.
The court heard Stewart admitted having sex with the younger girl on three occasions, twice in his car and once at his parents' home.
Fiona Swain, prosecuting, told the court: "This is a child who regarded the accused as her boyfriend.
"She still has feelings for the accused. She feels it was her fault for getting him into trouble."
Stewart, of Grampian Way, Thorne, South Yorkshire, admitted nine counts of sexual activity with a child, in relation to the 15-year-old girl, between October and December 2007.
He also pleaded guilty to five counts of sexual activity with a child by a person in a position of trust, in relation to the 17-year-old, between October 2006 and October 2007.
