.As soon as Julian thought he had enough dancing he began undressing me. I had not had a passionate sex where my partner, out of sexual passion, did n...ot waste any time in undressing me. Julian certainly appeared desperately passionate. He undressed me and went for my cock. His mouth surrounding the bulb of my cock and his tongue circling the bulb. He did that for a while and now he wanted to fuck me. (The mistresses checked with them first that they did not have AIDS or any other STD). I looked. Joan did not seem to notice my erections on these occasions, or chose to ignore them. She made many sketches, before choosing the positions she would like to commit to canvas. She told me that a few of her class wanted to know if they could try me out as a subject. I immediately agreed, and Joan charged them a little extra for these classes. We finished with an enthusiastic class of six, four female, two male, all nearing, or at, retirement age. Every twenty minutes or so, I was given a short. I've always been touchy about being seen in the nude but knew itwas unavoidable. Not that I have anything to be ashamed about. I'm abit shorter than average, not carrying any extra weight, with somewhatfine features and a full head of thick brown hair. And I'm quite manly,if I can be blunt, where it counts. Even so, I'd rather keep my clotheson. That what I was thinking as I finished getting naked and stood therecalming my breathing. Then I pushed aside the red curtain and tried notto let. Embarrassed, shy, and somewhat very turned on, I pretended that I had not seen him. A couple of hours later, the families were heading home and we said goodbyes. My new friend seems to linger and told me that her c***d had gone for a sleepover with another friend. It was just her, me and my husband eventually and I was very confused as to what I should do. My husband caught me alone in the way to the loo and brought the whole thing out in the open. He said straight out that if I wanted to be.
