My wife at a picnic

[Hurrel]

Last summer my wife and I attended a picnic with some friends; there were about 40 people there, we knew a few.
We sat at a table with some other couples, one who was a black man from overseas. He was in his mid-forties (my wife is in her early '50s) and I could tell she was attracted to him. I didn't think too much of it but later I seen both of them walking down a trail into the woods and which leads to a lake about 1/2 mile away.

I was very surprised, if it was innocent I believe she would have at least told me she was going for a walk but she hadn't said anything. I sat there for a minute and wondered about following them. It was exciting seeing her walk away with him and it started to make me hard. I wanted to follow and watch them if they had sex but I also loved the excitement of not knowing for sure. My wife has had sex with others previously so there was a good chance she would let him have his way with her.

I decided to let her have some fun if that's what she wanted. I waited for quite a while when I seen them return.
When she got close I was pretty sure by the look on her face that she had sex with him. When they got back to the shelter house they split company and she came and sat next to me. I nonchalantly asked her how her walk was and all she said was "it was fine" and dropped the subject. When we got home she undressed and while she was in the shower I went over to the laundry hamper and found the panties she had on; they had cum in them.

She had let him fuck her and I was wishing then that I followed them down the trail.

When she finished with her shower she came into the bedroom naked and got in bed. I was rock hard and wanted her so I reached over to her. She must have still been excited because I was soon slipping my dick in her. It didn't take long for me to cum in her since I was so turned on. When we finished she rolled over to sleep but did not act like anything had happened at the picnic. Over the next few days I would casually mention the picnic and even brought up her walk but she never said anything more about it.

I still get tremendously excited when I think about that day. I only wish she would confess to me and would tell me all the details.
