AND YOU NEVER WILL UNDERSTAND unless it's something you both agreed upon and are participating in. A good majority of cuckolds just do what they are told and they love it that way because we know we can never ever make her scream, climax multiple times and soak the bed.
My deceased wife of 38 years never lost respect for me and would actually get off watching me clean her BIG BLACK LOVER. She would rub her clit so hard and tell me to suck and lick his BIG BLACK COCK like a good little penis sissy. Before she died we seriously talked about it ALL>
She told me because you wanted me to have what I really needed and because you always put my needs before your own, IT MADE ME THE BIGGEST MAN IN HER LIFE even though I became a sissy, pantie wearing cuckold. She said it was better that way and I would never expect her to respond to her in the same way she did with her passionate, well endowed lover who had so much more stamina. That is why I would never be jealous. I knew she would always be my wife but understood she would always be her lover's woman and I would get to enjoy both the dynamics. People not into it that way will never understand the thrill. The reason most cuckold wives have such good lovers is because they are insatiable women. Their lovers big cock and passionate skills makes them respond the way they do, she doesn't have any control, it just comes out naturally. She cuckold me for almost 28 years and we loved each other to the end. Now I have a new woman in similar circumstances and it's great.
