You don’t know me all that well but we need to have a little chat. You’ve been dating my younger step-sister now for a while and I hear you are pressuring her to have sex with you. I’m sure you’re a good guy and all but I don’t think she is ready to give up her virginity at eighteen years old. This is where I come in. Any time you and my step-sister are going to go out I want you to come here early so I can jack you off. You’re going to give me your baby batter instead of filling her with your seed. She doesn’t need to know about this.
