That is how it would be for me too. My progression to becoming a cuckold has happened slow over time. It initially started when I heard my wife cumming in her sleep while she was talking in her sleep during a dream. It happened several times over a couple months and the 2nd time I knew I wasn't the lover in her dream and that he was well endowed.
Around the same time I realized how friendly/flirtatious she had become with certain acquaintances she had with black guys along with some sexual innuendos she started using. At first I was scared by this but over time the thought of it began to turn me on . Then one day when I was changing at the gym this young black guy had gotten out of the shower and was walking around the gym naked. He had one of those cocks that hung down his thigh and was very thick. He remained naked for a while in the locker room and as he groomed himself and as he walked back and forth to the bathroom. I couldn't help but look at him. I began to think if my wife would like this guy and I began to get a hard on. There were other guys in the locker room so I quickly dressed so they wouldn't notice. But from that day on I knew that I needed to be a cuckold
