My wife and I are in our mid 50's and have been swinging for the last ten years. However, we had never done any swinging without each other being nearby. Well, until this one time......
I had to make a business trip from our East Coast home to San Francisco. My flight arrived in the late afternoon and my first meeting was the following morning, so I went to the hotel gym to work out the kinks from the long flight. I was the only one in the gym until a few minutes into my run on the treadmill, these two women came in. One looked about 30 with long blonde hair, a slim figure and these very inviting 34D's pushing against her tight work-out top. The other women looked a few years older, had very short brunette hair and clothes too baggy to even guess what was underneath. Both women got on nearby cardio machines and I could hear them giggling during the rest of my run. After running, I went over the free-weight area and a little while later the women joined me. The blonde, Nina, and the brunette, Mary, struck up a conversation and I learned that they were also there on business as co-owners of their marketing business. Nina was clearly the more outgoing of the two while Mary was kind of quiet and didn't say much. After shooting the breeze for a while Nina suggested that we all go to dinner together. Mary didn't verbally object but it was pretty apparent that she didn't like that idea. I ignored Mary's reluctance and we made our plans. It was then time to get showered and ready to go out.
The Gym had its own shower area so one would not be dripping sweat all over the hotel to get back to one's room, however, there was only one unisex shower. The women suggested that I go first because they wanted to work out a little more. While I was in the shower, I heard their giggling again very close by and peeking around the see through shower curtain. I saw Nina trying to hide behind the corner of the wall while sneaking a peek at me with Mary right behind her. If they wanted a show, they would get one, so I vigorously soaped and massaged by package for my audience. When I went to turn off the water, they both snuck back out of the shower room.
After getting dried and dressed, I walked out into the Gym and told them whichever of them wanted next could go now. To my surprise, they went in together. Figuring that turn about was fair play, I waited until I could hear the shower running and went to same place by the corner of the wall. Nina and Mary's hands were all over each other as Mary massaged Nina's perfect breasts and I got my first look at Mary's nice body with finely-shaped 34C's. I was mesmerized by this sight while stroking my growing cock until I realized that I needed to get out of there before they left the shower. I did my best to hide my boner and went back to my room to wait for them to be ready for dinner.
