Do married women who cheat embrace the act? Do they get off on it?

I ask because recently I had one crazy-ass night with an older married woman I work with. We didn't have sex, but we made out, I fondled/penetrated her a-hole with my fingers, and she gave me a pretty good blow job in her car.

Some months later, she introduced me to her husband. For me it was a bit awkward, but there was such a smile and joy in her voice and face when she introduced us. And then later that day she kinda flirted and joked with me about the whole thing. So I kinda wondered if she actually enjoyed it and maybe even got off on it??

Can any other woman out there who has cheated give me their opinion?
