I caught my wife having sex with the old dude who lives next door to us. We live in a condo complex next to a single, older guy who is probably in his mid sixties. He is kind of chubby and bald, not much to look at, but he is very nice, especially to my wife. I don't blame him though because she is very sexy, in her late twenties, and has a great ass. He harmlessly flirts with her, which I ignore, because I figured she would never be interested in him.

One evening we had him over for dinner. We had a nice time and talked about his career in the military, sports, etc. I had put back one to many beers as I tend to do and fell asleep on the couch at some point in the evening. I woke up around 11 pm to find that my wife and him were gone.

I went next door to see if she was over at his place. I figured they went over to watch a movie and did not want to wake me up. Never did I expect to find my wife in his bedroom on her hands and knees with her ass sticking up in the air and this old dude pounding away at her. I did not know what she saw in him until he pulled his dick out. He was probably twice my size, so I guess she wanted to experience what a big dick felt like. I had been the only guy she had sex with until this guy. She really seemed to be enjoying herself and moaning a lot like a whore. I left and did not say anything to her. This was about a week ago and I am still stunned she would fuck an old fat guy. I guess size matters after all, at least to my wife.
