Most of the wives actually felt hurt because their husbands felt unable to be honest with them about their kink. All the wives on the programme ended up being supportive and one was really turned on by the whole thing.
The sister could be a catalyst in the plot but I would imagine the wives would feel similar sense of hurt and humiliation that the man resorted to his sister for help with his kink rather than them. I suppose a little ingenious writing could make it fly but you are not giving yourself much to work with.
