A kung fu teacher has been convicted of sexually assaulting two young girls in self-defence classes in Liverpool.
Peter Channell, 60, partly undressed the girls, aged nine and 11, kissed their necks and forced them to touch him, Liverpool Crown Court heard.
That would happen "for real" when an attacker struck, he told the girls.
Channell, of Handfield Road, Waterloo, Merseyside, had denied four counts of sexual assault, but was found guilty. He is due to be sentenced next month.
Channell was released on bail, but will have to sign the sex offenders register immediately.
The court heard Channell asked the girls if they wanted to be naked while learning a technique which involved them being blindfolded.
He claimed he was highlighting men's "weak points", which included the eyes, nose and throat.
David Owen, prosecuting, said Channell taught the martial art under the "pretence" of helping girls fight off attackers.
Channell provided the court with hand-written descriptions of the martial arts moves he claimed he was teaching the girls.
Mr Owen said: "The pages show the detail and degree of deceit in his perverted sexual desires.
"Looking at it more closely, it gives a disturbing insight to his approach."
