Are you nervous, honey? That's understandable. My Step-Daddy is a very intimidating man and I know you want to make a good impression. Don't worry! I'm going to help you. I'm going to make sure you understand exactly what is expected of you on your weekend away. You see, my Step-Daddy is the head of the household and he's going to want you to show him your submission. You'll do this by servicing his cock - sucking and fucking with appropriate obedience. I know it's going to be a bit humiliating, maybe even painful, but you'll do it for me. Won't you, darling?
