Four minutes after that Thompson urged her to show off one of the girls by abusing her on camera. He then exposed himself while the pair joked that the child would not know what was going on as she was so young.
When the victim complained about what was happening, they even used the chat language expression of lol which means laugh out loud.
The 24-year-old pervert then asked her to abuse the second sister, but instead the babysitter lifted up the youngsters dress for the webcam.
The weblog ended after 35 minutes.
Later that evening the family returned home and the mum discovered the damning computer weblog. It had been moved to the computers recycle bin but not permanently deleted.
I was in complete shock as I read it, said the mum.
Each line got worse and worse and I find it difficult to describe the feelings that came over me, it was just total panic followed by disgust.
I wanted to believe it was all a mistake but when I read it again it was obvious something very wrong had been happening and I called the police.
The harrowing court case was concluded at Birmingham Crown Court on Thursday where Thompson was jailed after admitting arranging and facilitating child sex offences and causing or inciting child pornography
KIRK THOMPSON WAS JAILED FOR ONLY 2 YEARS AND HIS GIRLFRIEND WHO I CANNOT NAME DUE TO LEGAL REASONS WAS PLACED ON A SEX OFFENDERS REGISTER. THIS IS NOT JUSTICE.
