I caught my sexy 28 year old wife fucking our 40 something year old neighbor. He recently got divorced and my wife had told me during the day that she would sometimes go over and check on him to see how he was doing. However, I did not realize how she was making him feel better until I cam home from work early a few weeks ago. When I got home I did not see my wife but knew she was around since her car was in the driveway. So I went next door to see if she was hanging out with our neighbor. I heard voices coming from his backyard and when I looked over the fence I saw my wife with her skirt hiked up over her ass riding the neighbor's very large dick on a lawn chair by his pool. I thought I would be pissed but it really turned me on. She was so sexy bouncing her ass up and down on his dick and I could tell she was loving it more than I could ever give her. I left before they finished and later that night I told her what I saw. She was really surprised it turned me on, but now the neighbor comes over a few times a week and I watch him fuck her. Our sex life has been so much better since I became a cuckold as I now fuck my wife almost daily and we both get off talking about him banging her.
