The progress so far, and where to go from there

Sounds like your dynamic is well directioned! The main point on having a "wife" to become a "hotwife" is about building her self confidence and letting her explore herself sexually while being a married woman. Let her experiment, try different things, talk about those things during sex, just make sure for it to a fantasy both of you can live, not only you as a cuck husband!

Quit right.
