Watching porn together with dad

My stepdad thinks I do not know what he does on his laptop, but I do. So when he asks me to help him fix it, I notice that he has a couple tabs of porn open. I act a little surprised, because I do not want him to be embarrassed. It is not a big deal. Sometimes he needs to take a little break. Maybe if I watch some porn with him, he will be able to relax some more.
