You never know what may happen. She's definitely had the seed planted in her mind. Perhaps someday you'll get to see her having sex with another man. But, if not, it sounds like you're having a blast already I've said here many times, but I'll repeat it here as it's apropos. In the years my wife and I were together before we got into swinging, I would have easily bet everything I have that she would never swing. She was absolutely 10000000% against it. Yet, here we are. You never know what may happen.
We soft-swapped with a couple that sounds a fair bit like you two. Neither of them had ever dated anyone else, much less had sex with anyone else. We played with them a couple of times, and had a very good time both times. The husband was very accepting of the idea of her having sex with other men, but it isn't what she wanted for herself or for him to have sex with other women. He respected that of course, and respected their wishes. It was in very sexy to be with her, knowing she'd never had sex with anyone but her husband. Kind of like forbidden fruit. Watching her have sex with her husband was a treat as well.
I think it's awesome that you helped your wife bring out her sexiness. There's a sexual fulfillment, a sexual awakening that is awesome to behold in such situations.
