Start "training" her

"Good morning, how do you feel my little girl?" You ask with a mocking intonation. Your father part is buried somewhere deep as you totally submerge in the most nastiest part of your mind.

"What is happening?" Jenna is trying to get her hands free and her panic raises. Seeing you totally naked doesn't help it either. Yet the situation is so bizarre that she still fails to understand what is about to come.

"Jenna, you are anything but stupid. You are naked and tied up. I am naked and you can see how hard my dick is. What is a logical conclusion? I'll fuck you and I'll fuck you hard" As her eyes go wide with pure shock and she fails to answer anything you continue "You see... you are an adult now and that means I can make you into my obedient fucktoy. And training starts today"

"Daddy, not... It is impossible. I am your daughter" She finally starts to talk and get rewarded with a hard slap in her face. In your story, which lays on the table in your room, Jenna will start enjoying it in the process if not that you wouldn't be that forceful "I am not your daddy anymore, Call me master"

"Daddy..." This time her voice is much terrified but you won't none of this and land a strike on her other cheek bringing both of them to sexy red color "I said call me a master!"

Jenna trembles with fear as you gently slide the very same hand that slapped her face along her neck "Be a good fucktoy and you'll enjoy it. I know that deeply inside it is what you have always wanted."

"No, daddy, please. Stop this insanity. I won't tell anyone" She insists on not addressing you in a way you desire. It may be a time for a more severe punishment for disobedience. Question is are you ready to really hurt your Jenna?
