A dominatrix has told how shamed driving instructor David Aston talked of his taste for underage girls as she whipped his private parts with stinging nettles.

Dominatrix Annie Jones, 51, said she first met Aston around 10 years ago when he employed her sexual domination services.

She said: "I could tell he was strange from the start.

"He was only about 21, but he wanted me to wrap stinging nettles around his groin and also to punch and kick him.

"He used to talk about liking very young girls, but I didn't think he was doing actually doing anything with them.

"I will tell police if I think someone is doing is something illegal.

"Now I know what he was doing, I wish I'd done more."

Mrs Jones said she last spoke to Aston around six months ago.

She said: "He was going to come and see me again, but then I didn't hear from him - I thought he must have been getting his pleasures elsewhere.

"I was really shocked to hear what he had been doing with young girls, but in some ways it doesn't surprise me because he was so strange.

"He should go to jail for a long time."
