A court heard Dominique Krief, who had responsibility for looking after vulnerable pupils, first preyed on his child victims after taking them to his home when they were aged 14.
Krief, a former Leeds United academy footballer who has also played for Harrogate Town and Farsley Celtic, continued to meet one of the victims and sexual activity took place in his car.
The 30-year-old, of Hammerton Drive, Garforth, also forced himself on a fellow teacher in a sports room. Philip Standfast told the court Krief grabbed the woman and tried to kiss her. He then told her he wasn’t going to let go of her until she told him she wanted to have sex with him.
The attack only ended when Krief was disturbed by a pupil knocking on the door.
Krief pleaded guilty to six offences of sexual activity with a child and one of sexual assault.
At his sentencing hearing yesterday, a judge read a letter from Krief, who was engaged at the time of the offences, which stated: “I am full of guilt, shame, remorse and utter disgust at my behaviour.”
Jailing Krief, Judge Christopher Batty said: “You were sexually attracted to them and you abused your position as a teacher in that school in order to get close to them with only one thing on your mind – your sexual gratification. It mattered not to you that they were your pupils. It mattered not that they were aged 14.”
