I was so surprised when my stepson came home from college early. I was in bed trying to make myself cum after a long day. When he walked it, I was so surprised that I actually got turned on MORE! I could see that he was getting instantly hard, and I really wanted to see his cock. I didn't stop him when he pulled it out. He watched me from the doorway as I fucked myself till I came. Am I a bad step-mom?
