I had often asked my wife to try a bigger cock but for years she refused. Eventually a friend came into our lives who she was obviously attracted to. I asked again if she would like to try and mentioned that I had seen him at the gym in the shower and he was huge. We invited him round for tea and had a few drinks, to give her a chance to bring up the subject I took the dog for a walk before bed. When I got home the living room was empty and the TV off. I assumed that he had gone home so locked up and went to bed only to find them in the bedroom. She was on her knees sucking him and compare4d to me he was massive. We all got on the bed but I was almost cumming straight away so she told me to get off and he took her. My heart was pounding watching them and seeing her legs up and straining for it all. Eventually I went into the spare room and lay listening to them, she was making noises I had never heard before. Eventually he went home and I got to have my go. She was the biggest I have ever felt and soaking wet. I don't think she even felt me. This was the first of many men after that.
