Several years ago my wife and I experimented with MFM threesome fun with a few of our mutual male friends. It was all about pleasuring my wife with no male-to-male contact unless by accident while we concentrated on her in double penetration. We both enjoyed it a lot and I enjoyed seeing her being pleasured by another man as I just watched and stroked myself. Time has passed and we're in our 60's and we no longer do threesomes, but I now find that when having sex with my wife I fantasize that I am one of them, or a stranger, having sex with her while I am away. It is almost always necessary to fantasize in this manner in order to maintain arousal or reach orgasm. Do any other men ever fantasize like this?
