I do have a past related to humiliation and ENF games with a past girlfriend. But my wife is a different story and I suppose the reason for my making my wife the center of my thoughts along these lines. Nearly all of it is fantasy with my thoughts about my wife being stripped naked at a dance club by some creep, and her standing there as everyone takes in her naked body. Because she is a haughty b*tch, I believe she would benefit from being stripped and humiliated.
The only real thing I've done to her is my brother and I allowed one another to secretly watch us have sex with our wives, including reverse cow-girl. My wife would die if she were ever to learn he had seen her in the nude and in orgasm. the memory still gets me hard. I wish I had more moments like that, but I do not.
