His Cousin And My First

I'm a divorced dad and I've always been curious about being with another guy. I was in high school when I first saw other guys naked when we had to shower after gym class. My stepson has a cousin close to his age that's gay and we started messaging each other a couple of months back. He started flirting with me and I flirted back. He said that he wanted to be my first and make love to me slow and gentle. We made plans to get a room for the weekend and we finally got together last week. We had sex all weekend but I loved blowing him much more. I'm worried that he's going to say something to my stepson and show him the pictures.
