Beach With Parents And Aunt

My aunt is divorced and is a good friend with my mom. Our family always goes to the nude beach. I don't really like it, but I have to go or else we don't to to the beach at all. So we went, this time bringing my aunt. I have never seen her naked, but she is only in her early 30's and seeing a naked woman made my dick semi-hard. I knew for a whil that my dick was bigger than my dads, but nobody ever mentioned it. My mom and dad went to swim and my aunt and I stayed to watch our stuff. My aunt turned to me, looked down and said: "that's a very big cock, I bet you will make a lot of girls happy in your life...a lot". She said the second "a lot" very quietly and gently brushed her nipples. I will be honest, I was too shy to say anything back and walked away, since my dick was getting very hard. She hasn't mentioned it since, so I hope everything is okay.
