Caught him watching porn in the living room..

I caught my dad watching porn in the living room. My mom and I always suspected he was because she found it on his tablet before, but this time I walked in to find him watching it. This is the first time I’ve seen him doing it but I’ve heard it before because he always has the volume up so loud on all his devices but he’s denied it. 🙄 This time he couldn’t. What would you have done? He got mad and yelled at me. 🤔 He’s just mad that he finally got caught.
