Stranger at the beach

I was just making some nude beach content for you on a near by beach, and suddenly I notice this guy standing bit further and watching me. I did not say anything at first, but continue to do my stuff. He started coming closer and closer, and I did not object. It's been a while since I had sex, so I was in a really good mood. And the warm late day summer sun made me feel really open to this kind of flirt. What do you think happened next?
