A South Australian survivor of child sex abuse has told a court how he became a "sex slave" as a child for a schoolteacher he wanted to be a "father figure".
Former Adelaide teacher Bevan Charles Wilson, 72, is awaiting sentencing in the District Court for maintaining a sexual relationship with a child in the 1990s.
Judge Jane Schammer last month found Wilson guilty after a trial.
Today, his now 41-year-old survivor read a statement to the court, saying his life was "torn to pieces" by Wilson.
"When I was a child, I wanted a father figure in my life because I didn't have one," he told the court.
"I wasn't so wrong to think you'd be a father figure … but I thought you were going to kill me when you flicked that evil, twisted switch in your head.
"You were, and still are, a monster — a vicious and scary one."
He said he never imagined he would start dying "piece by piece" in his childhood because of Wilson's crimes.
"You made my childhood something I was ashamed and embarrassed by. I felt humiliated and scared — I started to hide from the world," he said.
Survivor turned to drugs to cope
The survivor told the court that he turned to drugs in his younger years to "numb the pain".
He said he reported Wilson's crimes to police when he was 35 years old, and the court process had taken up the past six years of his life.
"It has brought up lots of memories and trauma of what you did to me. I've had to be brave enough to remember the past which I try to forget," he said.
"To get justice, I had to relive and bring everything to the surface again — the process has broken me."
The case was adjourned until September so Wilson's lawyers could seek a medical report about his Parkinson's disease and dementia.
Speaking to the media outside court, Wilson said he had no remorse.
