Being in the defence force, I mixed with various people, and being young and single created exciting opportunities. A word about my member size also sparked curiosity among men and women alike. Just for the record, I am straight. My only involvement with naked men is when we are sharing a woman.

One such experience was with a work colleague who invited me to a BBQ with his friends and family. I met his wife for the first time, a tall brunette with a womanly body, lovely hips, and D-Cup breasts. She was in her mid-thirties, and they had a couple of kids. The next day at work, I thanked him for the invite and how much I enjoyed the day. Then, to my surprise, he asked me straight out, “Would I like to fuck his wife”. I managed to stumble over a reply that I would.

He continued to explain that he would like to know that his wife was sleeping with other men and would like to watch at times. He also would like his wife to have sex with a group of guys. Finally, he shared that he would like to invite me around more often and wanted me to get close to her and see if I could seduce her.

Over the next few weeks, I would visit for drinks and meals and join them on family picnics and visits to the beach. During that time, I developed a friendly relationship with his wife. Sometimes, I even thought she was flirting with me when he was not around. But it was a day at the beach when we finally broke the ice. He was playing with the family in the water, and I stayed with her, sunbathing on a towel. I noticed she was getting sunburnt, and I offered to apply sunscreen. As I used the cream on her back, she commented on my hands’ strength, which felt good. I lay the cream on the back of her legs and moved slowly to the top of her legs, and my hand caressed the cheek of her bottom. She moaned, so I let my hand continue under the bikini bottoms. My fingers were now between her cheeks, and with the oily cream, slip my hands down between her legs. I gently explored the tight muscle between her anus and vagina.

At this stage, I was confused, and my heart was pounding out of my chest. My mate had explained that his wife was pretty prim. So here I am with my fingers at the edge of her vagina on a public beach as the family played nearby. As I allowed my fingers to explore further, the family raced up from the water.

As she sat up, she just smiled at me and then turned and kissed her husband as he flopped down on the towels. I was excited to see if I could create another opportunity and see how far I could go.

The rest of the afternoon was uneventful. We had dinner, sat around listening to music, and chatted over a few drinks. The family had retired to bed and suggested we jump in the hot tub for a while. I didn’t have bathers with me, and as I didn’t wear underwear, I would have to go naked. She said she didn’t mind and would look away.

We climbed into the hot tub. He and I were naked, and his wife wore a black string bikini that didn’t hide much. We sat and talked as they sat on one side of the hot tub, me on the other. They sat close to each other with his hand in her lap. Then, the subject switched to sex, and they quizzed me on my sex life. I explained my disadvantage and how most girls are scared off. She laughed and said I should focus on women with kids. They would be interested.

He excused himself for a bathroom break as we continued chatting. Then, finally, his wife confessed to me that she thought her husband was trying to encourage her to have sex with me. She was confused but said that if he wanted to do this, she would go along just once because she loved him. I sat there for a few minutes, contemplating the next move, and decided to slide over and kneel in front of her open, stretched legs. It was very erotic being this close to her. I was looking into her eyes, and I could sense her arousal by the circumstances and what might follow. We kissed slowly and passionately as my hands explored her body. The warm water made her skin smooth as I ran my hand over her sides and back.

As we kissed, I heard him coming back, and he laughed and commented that we were getting to know each other better. He was, by the look on his face and a growing erection, excited by the scene. As I sat close with my hand, exploring his wife’s exposed breast, she explained this would be the only time it would happen. She was not interested in having sex with other men or me, but she would do it tonight if he wanted this.

They agreed as she removed her bikini top, and I held her close and kissed her, feeling her breasts against my chest. As we continued, he made another request and asked if he could take photos. She agreed and asked if I would mind. It sounded like a great idea. He left to find his camera, and she suggested we find somewhere more comfortable, her martial bed. We dried, and she removed her bikini bottoms and, taking me by the hand, led me to their bedroom.
