Keep one thing in mind, bob. 80% of the stories you read here are pure bullcuckolds brownie, as are most cuckolding stories. There are some real people here, and I'm sure some very real cuckolds but the stories people tell are the cyber equivalent of Penthouse Letters. If a story starts out with "I can't believe this happened" then chances are it didn't.
I too have fantasies about my wife fucking other guys, but I seriously doubt she'll ever do it. From time to time we'll play bedroom games along those lines but that's pretty much it. A lot of the guys here talk about eating sperm out of their wive's pussies and sucking a bulls dick but if the were  
really presented with sperm dripping out of their wife or a big black dick in their face they would run for the hills. I permisterally have no desire to do either one. The "true" stories, and "real" vids here get us off, but most of them are just wishful thinking.
Here's a perfect example
