The scene starts with your step-mom coming to find out what you want for dinner. You know she'd do anything for you. She explains how she REALLY loves you. She's teasing you and showing off a lot of cleavage and of course she spies your boner! She tells you that your boner means that you feel the same way as she does, you have a mutual attraction. Some people will say that's wrong but she convinces you there is nothing wrong with this kind of relationship and you are soon balls deep inside your step-mom ;)
