Step-Mommy gets an email from your school, your grades are back, but they're not what she was expecting. You're usually a Grade A student, but suddenly you've started to fail your classes. Step-Mommy tries to talk to you, and eventually you tell her all about the girl you have a crush on in your class, you get distracted by her, but she will never go for you, she's kissed a lot of boys, but you don't have any experience. Step-Mommy is shocked, and hurt that you're interested in another girl other than step-mommy, she sounds like a slut, kissing all those boys! You don't need her. But you tell her how sad you feel, and step-mommy decides that the only way for you to get kissing practice, is by using step-mommy. You can use her big fat lips to kiss, and step-mommy tells you how much girls love their asshole and pussy's kissed too, so you better practice on her too. Don't worry about your cock twitching, if you need to stroke step-son, then do it, you and step-mommy can cum at the same time whilst you kiss step-mommy's holes.
