Sure, I bet it happens to one degree or another fairly frequently that a wife looks at her husband differently when she sees him in a submissive role. I accidentally caused something like this without the physical punishment progression. My wife's sister and husband are big into swinging. With their urging and my support, she has discovered the fun in these activities when she goes across country to visit them (nothing with either of them, but they set her up with guys from home parties or clubs). She is shy and submissive and these trysts have really stretched her plain vanilla comfort zone. Her head would swim and she would come back with limited details, telling me she was so overwhelmed that she often felt like she was out of her body watching herself, dreamlike. So I'd get a rough description of each guy and what they did and then she would be done talking about it.
So she would come back and dismiss the events like a fact of "we went to the zoo and then out to dinner" Whereas I was sexually exploding in fantasy and masturbation, wanting to hear every detail repeatedly. All this to say I was so obsessed with seeing her fucked that I answered a bull's ad on Craigslist. Over a few conversations, I told him all about her and my situation, and he played my need to his full advantage. We worked out a plan where he talked to us both together and then separately. My wife was not keen on any of this but I begged and begged. I gave into his reasoning that he should just take her out alone and then start getting her comfortable with him doing her in private. In fairness, she was coming around. Although she gave me little detail, she was wanting to continue seeing him. Only later did I realize she was much further along than he let on as he used my info on her submissiveness to push hard at training her to be his little slut.
So finally we get to the day I am allowed to watch and I am totally blown away by what she is willingly doing for him with no hesitation. My straight vanilla wife was a different person. This made me so nervous and uncomfortable - I thought she would be embarrassed but instead I was. Then he turned on me and made me submit and put me through similar paces. He was a different guy than the one who would always be reassuring me how he was helping our marriage. My wife to was shocked by the whole thing so it wasn't discussed with her ahead of time either. I understood what my wife meant by being out of your body as I felt frozen, not even sure how I was eventually found myself just following his orders unquestioningly.
Afterwards and in the months to come, she would tell me that she was totally repulsed and couldn't unsee what happened. It killed her sexual interest in me although she still loved the other aspects of our marriage. At first she didn't think she wanted to have sex with him again but his alpha demeanor was too much to resist. So surprise, they both decided that it was best for all if I stay home and the two of them continue to meet. This was a few years back and it lasted another 6 months. My wife is back to low key normal but twice has taken on boyfriends as her needs ebb and flow. We sleep naked in the same bed and touch each other daily. I will occasionally service her orally but intercourse is very rare.
She has been flirting with a new guy and is close to closing the deal. One of the first things she told me after their first date is that he is the type that won't want to share her. Half of me finds this over-the-top exciting (think adrenaline rush) and half of me is afraid to death of where this could go.
