We've been teaching our step-son and step-daughter since I can remember that it is not only fun to fuck your step-family, but it feels good. They know it is natural for a step-mother and step-son to fuck, a step-daddy and step-daughter, or a step-brother and step-sister to fuck. My step-son is a little nervous about going away. He's going to miss fucking his step-mother's pussy whenever he likes. I love fucking my step-son. He knows that. Good thing I'm sending his step-sister to join him. She'll be able to give him pussy whenever he needs it. There's nothing likes a step-mother's love though, or her pussy
