Caught jerking off! Stepdad jerks off on my videos

For the weekend I was back with my stepparents. When I got out of the shower in the evening, I wanted to go back to the bedroom to get my stepmother's skin cream and then the shock! The first thing I see is a huge thick hard cock smiling at me. My stepfather lies on the bed and jerks off on my videos that he downloaded from the internet. How perverted is that?
