I have always had fantasies about other guys we know fucking my wife, then one night I just came out with it during sex and mentioned one of the guys. She liked the fantasy and as she sucked my cock, she told me "Show me how he cums in my mouth. Then we had a few 3sums with a work friend of mine. But for a long time back in the 70's-80's I never really heard of the term cuckold. That came to me through sex stories. Then the cleanup cuckold stuff that really gets this old cuckold off. At first it was just thinking of other guys fucking my wife, and the wife sharing during our early days 3sums.
