Bratty, demi-sœur, humiliation des pieds

Well, well, well... if it's not my stepbrother! You look really embarrassed. What's the matter? Do you think I'm going to make fun of you? I am because I know your dirty little secret! What is it about feet that causes you to get so hot and bothered? And it's not just any feet. It's my feet. My feet drive you absolutely crazy. They make your little willy get bigger. Oh, and it's not just my feet that drive you wild. You like stepmom's feet, too! If only she knew you were wanking off to her feet! What a sticky little situation we have here, dearest stepbrother. What shall we do? We can't have you walking around getting a boner every time you see your stepmom's feet or mine. And what would your friends say if they knew? I could ruin you if I wanted, but I think I'll just make you do things for me. Lots of things.
