My Forever Secret

At the time my wife and I were in our 30's and her parents were in their late 50's. My wife at the time was relating stories to me that her parents were having problems. Her dad was telling her that her mom was very cold toward him and wouldn't take care of his needs. I really didn't think nothing of it. One night we went to a family celebration and on the ride back home my wife drove and her dad rode in the front with her. My and her mom were in the back seat. It was a dark road with an occasional light along the way. Several time when the we came up on a light I could see in between the front seats and I noticed dad's hand on my wife's leg. The more lights we passed the farther up her leg his hand was along with her skirt. Her mom was cuddling up to me but she wasn't seeing what I had in view. We got home and didn't think nothing of it. I would get off work at noon and her mom's house was on my way home. I noticed my wife's car there so I decided to stop by. I let myself in but the whole has was quiet. I went to the far back bedroom and the door was open. I was surprised to see her and her dad in bed. I could see them through the mirror and I was well out of their sight. They were naked in bed fondling each other and kissing. I was in total shock but very turned on. I then saw him turn her on her back and he mounted her. He was fucking her slow and deep and kissing very erotically. Finally he started short stroking fast and he cum in her pussy. I quickly rushed out of there quickly. It's been my secret to this day and now in our late sixties, I think about it and we still fuck good.
