I suspect she must got some sort of naughty thrill out of posing like that. She was maybe just too embarrassed to tell you about it.
I can imagine a lot of very personal questions when your wife was already very nervous being a bit of a shock but I suspect they would need to know all that stuff...
I can't see her not getting a thrill and a buzz out of doing it even if she was really nervous. I have done a couple of topless boudoir shoots myself and I was really nervous and self conscious certainly the first time but doing it made me feel very naughty and I have to admit that thrill and...
That's a shame if she was more nervous than excited about doing it by the time she was having her hair and make up done for the shoot, most women would have found that part quite relaxing and a treat.
I can understand how a lot of waiting about with just her own thoughts about the shoot running...
So was your wife nervous about the shoot or excited about doing something naughty and daring at that point when she was sat there ?
Strange for them to ask her to wear such an ordinary outfit for a topless shoot.
