When I arrived to where they were staying I was knocked on the door where he answered with a beer in his hand shaking my hand he told be to take the b...er and sit down and relax on the bed and I was welcome to more in the mini fridge if I wanted some. He sat down in a chair and we made small talk. I asked where was the lady and he said she was freshening up in the bathroom getting ready.He called for her and in a few moments she came out in a sexy pink nightie complete with black high heels. I got up with my wife but she pushed me back down and she said, “My rules remember?” She went back and I could hear talking but couldn’t really make out anything. Finally, I did hear my wife say, “No leave the door open.” Then I could hear the unmistakable sounds of sex. I waited a little and started to look down the short hall to the bedroom. The bed was oriented so you could see right down to the little den and out on the deck. As I turned I caught a glimpse of my wife’s ass as she was. She is 5’5″, black eyes, brown streaked hair, about 60 Kgs. She was wearing a 34B bra and size 4 panties at the time, all packaged very nicely! I should know about the sizes. She started to visit me at my office almost everyday, I’m the only person in the office and soon things got more intense! We started to make out like kids in an car, both holding back because of our family relationship, but both knowing what was eventually going to happen! When the moment came that we decided to meet at a. I knew he’d be able to see the lacy top, knew he’d be able to see a glimpse of my pussy as he ran his hand appreciatively over the fine nylon. His next movement surprised me a little. Pushing me away dismissively he lay back and folded his arms behind head, watching me and inclining his head down towards his groin. I stood for a moment, the sensuous moment lost. In that one small movement he had reminded me this wasn’t a seduction, this was a business deal and I had been bought for his.
