A few days later, Karen had to meet a client in a town around fours hours drive. She said she would stay overnight, and I offered to accompany her and share the driving. We left early, and Karen was dressed in a tight-fitting knee-length dress as the meeting was in the afternoon. We left early in the morning, and as we drove, we talked about her work, life, family and eventually sex. By this time, I was driving the car, and Karen had her hand in my lap, her fingers lightly caressing my erection. The more we talked about sex, the harder my erection got, so Karen unzipped my shorts and was now stroking my erection. At the same time, I leaned over and encouraged her to raise her skirt, and I could see her panties. I then asked her to lower the top of her dress. So she leaned forward, unzipped the back, lowered her dress, and sat topless for an oncoming vehicle to admire. Karen caressed her breast when trucks approached, waving so they might see.
We were now driving alongside a railing line, and she asked me to stop. So I stopped the car between the road and the railway, and Karen said she wanted to fuck me. I jumped out of the car and walked over to her side. She opened the door ad standing next to the door, leaned over as I lifted her dress. She pulled her panties to one side, and I rubbed my cock against her vagina. She looked over her shoulder and said, "fuck me". I grabbed her breast and started to fuck her with deep quick strokes. It didn't take long before I could feel my orgasm approaching. Karen was already coming hard with her orgasm, and with no one around, she was calling out to be fucked harder. As I was about to come, when I heard a train approaching, so I stopped. Karen told me to keep going. She wanted them to watch. So I fucked her with all my strength. She was pushing back hard against me. We both came, me thrusting deep, Karen pushing and panting as the train roared and raced past. Karen then waved as the drivers sounded the horn.
Later that day, Karen finished her meeting, and we shared a coffee. Karen smiled, saying she enjoyed the conference, with her panties soaked, and she could smell the musty aroma between her legs every time she moved. We rented a ground-floor apartment on the beachfront without sharing it with family and intended to sleep together that night. We shared dinner at the local restaurant but hurried to return to our room. We had sex a few times at that stage, but sleeping with her was a new dimension I was looking forward to.
Returning to our room Karen started to undress, so I went to close the curtains. She asked me not to, as she enjoyed showing off. She said when Steve was away, she sometimes left the curtains open at home and often flashed her breasts as passing truck drivers on her long drives. So we undressed and sat naked, watching television and chatting in full view before the open glass doors. As we sat and kissed, Karen lay back and started caressing her stomach and tracing the edge at the top of her trimmed pubes. As she did, she hoped some young guys could see as she teased her clit. At the same time, I stroked my cock, watching as she started to masturbate in full view of anyone outside. Her fingers were teasing her clit, exploring her lips, and opening herself. She was aroused and wet as her fingers explored deep inside her vagina. Finally, I could not control myself any longer and climbed between her legs, held her legs fucked her long and hard. I am sure if anyone were outside, they would have heard if they couldn't see us. We fucked again that night with the lights out, but it was erotic as we could see people walking along the beach. We drove home the next day and talked about our previous sexual encounters and found a new depth to our friendship and relationship.
Just before my wife and I left to return home, we visited for a family BBQ, and I was helping Karen in the kitchen. I noticed carpet burns on her the top of her feet and knees. She smiled and told me she had sex with a guy at work on the boardroom floor, she was on top riding him, and that is how she sustained the injury. She said she came home late with wet panties and had to shower discretely to clean up her mess, and Steve had not noticed anything.
At the end of our visit, we returned home. Unfortunately, we lost direct contact with Steve and Karen. We later learned they had separated a few months after we left. I remember thinking Steve should have tried and worked that one out as she was hot and had good fun, but a bonus was her sexual attitude. Unfortunately, our marriage was also in trouble, and about a year later, I was back to being a single guy.
