Hi sissyj! Feminization is one of my favorite activities. I always appreciate a certain degree of self-care and vanity, and of course love to humiliate subs through it. I find that "girl talk" often happens as an extension of the humiliation - that you're not enough of a man to talk about "guy things", only "girl talk" for you!
Double domme sessions are super fun for feminization! It wouldn't be a waste of all, in fact it means we can go through different outfits!
