It was during this period that he photographed his mother-in-law topless without her knowledge or consent.
He also repeatedly played pornographic movies in front of her and his sister-in-law while giving them lifts in his car by placing his phone in the car's centre console in clear view of his passenger.
The second time it happened, his sister-in-law plucked up the courage to tell him it was inappropriate and he stopped.
When his mother-in-law found out, she admitted the same thing had happened to her.
Previously she had been been too embarrassed, ashamed and humiliated to say anything about his behaviour.
Jenkins' marriage deteriorated and when he moved out of the house photocopies of the secret photographs were discovered among possessions he had left behind.
He told police the images weren't photocopies or even based on photographs, but rather images he had drawn freehand that were created in his mind.
He also denied any of the other behaviour, claiming the issues had arisen due to family conflict that was before the courts.
He was released on bail on Monday to appear again in August for sentencing.
