I feel like I have cheated on my wife but I don't think I am responsible for it. I give my wife massages and am pretty good at giving them. A nearby neighbor who is a friend of ours was offered, by my wife, a massage by me. I thought it would be innocent enough but I was still a little concerned. I figured my wife wouldn't have me do this if she thought something may happen. Also the neighbor was married so I was probably just worrying about nothing. I went over to her place and her husband was away so it was just us. She asked where the best place to do the massage would be. I mentioned something like a couch would do. She suggested we just do it on her bed. She told me to wait in the living room as she got undressed. She left and came back with a towel wrapped around her. She led me to her bedroom and pulled the covers off the bed leaving just the sheets. She tossed her towel away and jumped on the bed face down. She was fully nude. I mentioned I only give massages to my wife and this could be awkward. She asked how I massaged my wife and I told her I would get on top of her with a knee on each side of her and her between my legs. She said she didn't have a problem with that. I got on top and she quickly stopped me and told me to get off. She undid my pants and pulled them down along with my underwear. She then removed my shirt and socks leaving my just as naked as her. She got back on the bed and told me to get on top of her again. She mentioned it was more comfortable for both of us this way and there was no need to mention any of it to our spouses. I had my hands all over her back and my cock and balls were pressed up against her ass. It was time to do her front and I told her to roll over. I was getting a view of her tits and pussy and she was getting a good look at my cock. She told me to fuck her. I told her I couldn't. She said she could see I wanted to referring to my hard cock. She spread her legs and told to not disappoint her. I couldn't resist and did as she asked. There we were fucking each other. I never finished massaging her front but she didn't seem to care.
I left and my wife called her to asked how the massage went. Later my wife told me what she said. She told me the neighbor loved the massage and asked for another. My wife told me that she told her that I would be over there in a few days to give her another one. I knew I should have said NO but I did go over. There wasn't any massage that happened this time and it was basically us have sex again. She was more satisfying than my wife which made her impossible to resist. This went on for months until the neighbors had to move away due to the husbands job.
