I am happy to say that many of my fantasies have turned out to be her fantasies too... SPH, cuckold role play, chastity, corporal punishment, etc.
I do recall a specific event that was her indulging me in my fantasy at my request. I think in the end she quite enjoyed it too, but this was definitely something I asked for and she was very kind to do for me... I described a scenario where she led me to the basement and ordered me to strip completely naked, and then she cuffed my feet and hands and lifted my hands all the way above my head using a rope strung over a beam and then securely tied. My mouth was gagged. She then would proceed to spank and whip and flog me, pour hot wax on my chest and caged genitals, and tease and torture me. And then blindfold me and leave me there alone in this incredibly aroused state as she went about her business, talked on the phone, perhaps even answer the door and let someone into the house leaving me worried I might be seen this way. Finally, she would come down and recline on the couch near me and use her favorite dildo and vibrator to get off while I could just hear her whimpers and moans and not see or do anything.
I have to confess this fantasy still gets me hard as a rock. But more so because just that one time my wife pulled it off absolutely perfectly, and in my mind I can still visualize it and even feel some echoes of the pain and arousal.
