After my first deployment, I returned home for a much-needed rest, and fortunately, it was in late November and the lead-up to Christmas. The festive season and warm summer days at the beach were relaxing. To keep my fitness up, I would swim for 5km along the beach behind the surf break. As I merged onto the nude beach, there would be people sunbathing and playing on the beach. I would remove my swimmers, and as I was extremely muscular and fit, I noticed some of the women and men would be looking at me. It was great for the ego, and I would walk back up to the barracks to shower and change. As I did, I admired the women, some hard great figures and wondered if they were swingers, shared wives or would cheat on their partners. The idea of having sex with some of these women would start to give me an erection. I am not a small guy even after a swim in cool water, but by the time I had passed, I was definitely bigger.

One time, as I walked back up the beach, I passed a young family, and as I did, the woman asked if I had enjoyed my swim. We started chatting, so I sat next to her, with her hubby on her other side, while the family played in the water. They were both fit and confident being naked. She had a great body, suntanned and shaved. He was very friendly as we chatted, and they asked if I would be interested in coming over in the afternoon for a swim in the pool. They gave me their address, put my swimmer on, and headed for the barracks for a shower and lunch.

I arrived at the address around 2:00 and was greeted by my husband, Adam. He showed me through to the backyard and swimming pool where they were swimming in the pool. I noticed they had swimmer on and was glad I was wearing mine. His wife Clare waved and invited me in, and I stripped on my shirt and joined them in the cool water. Adam bought out drinks and wet sat around the pool edge. They were curious about my work, as they were in the medical field, and I learned they were doctors. At that point, there was little physical contact and no mention of anything sexual. So, what happened next caught me by surprise.

I asked Adam if I could use the bathroom, and he suggested I use the ensuite to their bedroom; it was closer. He suggested Clare show me where to go, and I followed her down the hallway. It was a nice new modern home with good quality furniture, fixtures, and air conditioning. When I finished my business and went to walk down the hallway, Clare was standing in the kitchen. She smiled, and I walked up and asked her if she needed a hand. Clare looked out through the window quickly and then back at me. With one movement, she stepped towards me, grabbed my face and kissed me the longest, passionate kiss I had received in months. Her hands were exploring my chest and upper arms. Clare was almost breathless as she told me to follow her into their bedroom. As we walked back down the hallway, she held my hand with one and untied her bikini top with the other. We stopped at the end of the bed; she removed her bikini bottoms, and I removed my swimmers. Laying on the bed with her, she wrapped her legs around me, kissing me passionately again. I guided my erection against her opening and slowly allowed her to relax and take me into her. She tilted her hips up and groaned as I went all the way. I started long, slow movements as she moaned for me to fuck her hard. So I rested on my hands and pulled her legs up and did just that. She was groaning and continued asking to be fucked hard.

I must have looked distracted because she told me not to worry. Adam enjoyed watching her fuck. That idea must have been just enough to see her crash into an enormous orgasm. As she lay there panting, one hand on her forehead, I continued pumping her wet open pussy. She smiled, and when I looked out the window, I could see Adam watching from a distance. I thought to myself, if he want to watch, then we can give him something interesting.

I grabbed Clare, rolled her over, and pulled her onto her hands and knees. This time, I moved around so she could see his wife being penetrated nice and deep. The act of being manhandled and taken from behind must have been erotic as Clare was coming again. This time, I could feel my orgasm build, and I came, and I knew it would be a big load. I made sure it was not too deep because when I pulled out, I turned her arse towards the window. So he could see my cum dribbling from his wife onto their martial bed covers.

Clare rolled over, and as she looked up at me, I climbed back between her long, shapely legs. I looked into her blue eyes and noticed her long blonde hair was a mess; her large, full breasts and pink nipples were warm under my caresses. I leaned over and kissed her again, and I could feel my erection growing, pushing against the soft folder of her vagina. As my tip disappeared, she stopped me and suggested we go outside before they came looking for us.

I went outside dressed in my swimmers with a glass of cold water, the aroma of her sex on me. Adam looked up from his deck chair and smiled; I knew he had seen us. As I sat down, Adam suggested I stay for dinner, and when the family was in bed, we could have a video night—the rest of the afternoon passed quickly. We enjoyed a healthy dinner and a couple of glasses of white wine as we watched normal TV shows with the family. It was kind of nice to be away from the guys at the barracks.
