Kris and Kevin are into it big time doing a hard core “69”. I notice that Kevin is hard. He is not longer than me, he is about the same length, bu... he is much thicker than I am. Kevin then starts fucking his wife doggie style. He is giving it to her hard and fast. Kris is loving it, but at the same time she is also watching us.This is when the problems started. I was too scared and/or nervous being naked in front of my wife’s friends. I couldn’t get it up. Soft, I am no longer than 2”. No. It would never do for his wife to find any trace of his time here upon his person or his clothing. So he used the shower here, kept clothing in the modern bathroom to change into when necessary. He never worried about her coming down here. He had brought her down here himself before he had done any of the back breaking work. Had brought her down the rickety steps and taken her into the damp, dark cave full of cold stale air and creepy, squirming bugs. She'd lasted all of two minutes before. "I said, "That is what makes it so exciting, and since we will never see him again, and he obviously enjoyed it, because you are one sexy woman, what is the harm?"She just stared at me, but I could tell that she was getting interested and was flattered by the look she got from the truck driver.I said, "Look, let me pull next to another truck, you look at the driver, and if he looks interesting, let's make his day. I know it will make mine, and I think you will enjoy the attention."She sort of. I did as I was told. I was sure glad I’d read a few porno stories. I wanted to do this right. I remembered they said to always be gentle. Don’t grab or squeeze a woman’s breasts until your partner is ready. She put her hands behind my head and pulled me to her breasts. Damn, this was good. Now I wanted more. While sucking her nipples I undid her belt and the buttons on her pants. I opened them and pulled them down her legs. She was now standing there in her panties, sexy ones too. She told me.
