Since my divorce four years ago, my son, who is twenty-four and unmarried, and I have started to actually become pretty good friends. We always got along all right, but now he is older and lives on his own, there is not that mother-son friction, and we enjoy each others company. One day we went out to lunch together, and we were driving back along the coast. We came to this nude beach. At least the people there were nude. We were both surprised and thought that it was amusing. Just for fun, we thought that we would give it a try. So we got undressed in the car and walked down. We had never been naked together, so this was quite bold. But no one paid any attention to us, and after we got past our initial moment of modesty, it was fun. We walked along, and then we went and sat on the sand. While we were sitting there, my son got an erection. I could see that he was self-conscious about having that happen. I assured him that I wasn't embarrassed. In fact, I felt quite flattered that he could get an erection with me like that, and I can tell you that it was a very large stiff one! We both sort of just smiled and laughed about his physical display. Teasingly, I gave his hard penis a feel and we did a small kiss on the lips. Then we went back to the car to get dressed, and on the way his erection wnet down. Since our naked moment together, we've both joked about it, and there has been this sort of unspoken desire to maybe enjoy something like that together again, and not at the beach, either. Only so far we haven't.
