"Now darling," Diana said, her voice slightly amused. "Don't play with your pussy right now. Just imagine you're having your period, dear. Girls do... you know. I told you I want your body to feel feminine inside and out, and there's only one thing you can put into that opening that would make you feel even more feminine, isn't there? You don't want that just yet now, dear, do you?" Bob wasn't sure he had heard what he had heard. "What?" was all he could utter.
