mommy has been working out lots and it sure shows, doesn't it stepson? Are you impressed at my booty gainz and how large my biceps are getting? It seems to me you are VERY excited! Each time I flex you get excited down there! Does it turn you on to have such a muscular stepmommy? All of your friends have fat, ugly stepmommys but you have a hot one. I think you love it when I'm home flexing, it's like to never go out anymore. This black latex dress sure shows off my sexy muscles. Maybe you should show me what my muscles do to you. Kneel in front and I want you to milk for my muscles. It's ok you need the practice and how else will you learn to milk yourself if stepmommy isn't guiding you?
