I had been urging my wife for some time to join the club but she had been reluctant. However on this flight I convinced her to only wear leggings and a sweatshirt, I was in shorts and a tee-shirt for the possibility of some fun in route.
After we had leveled at 7500 feet and the three kids in the back had passed out we started with the foreplay! It was difficult putting the seats of the 172 back far enough and trimming the plane to stay somewhere near our altitude. Finally we worked all that out and we had our clothes off and I rolled over on top of her. Her breasts were bared and nipples erect. As I kissed her we started to engage in the act. She was ready and came before I had a chance to really enjoy myself. A few moments later we were both satisfied and relaxing in each others arms.
It was then that I looked up and saw my four year old looking at me very strangely! I rolled over and got things under control before starting my decent into Reno. My daughter never did mention anything to me and I never brought it up!!!
