Your step-mom is pregnant and has to talk to you about your time together and how that will change now that she is expecting. And all her breastmilk is going to have to go to your step-sibling now. But she tells you not to worry because step-mommy is going to turn you into a good little cocksucker. You can enjoy all the yummy milk you want and need from your step-dads cock. Don’t worry, step-mommy will tell you exactly what to do and how, and she encourages you to stroke yourself while she tells you all about how to suck your step-dads cock and get all the milk out.
