The jury in the case of a married driving instructor accused of getting underage girls to kick him in the groin have retired.

Father-of-two David Aston, 32, denies denies sexual activity with a child, causing or enticing a child to engage in sexual activity and making indecent photographs of children.

The jury at Oxford Crown has been told Aston, from Bell Close, Cassington, near Witney, met a girl through an Internet chatroom and arranged to pick up her and her friends on two occasions in 2006.

He then asked them to kick him in the groin. He is also accused of engaging in a sex act.

Aston told the jury he believed the girls were over 16.

The jury retired at noon.
