I caught you doing something, while I was quietly stood outside your room. You were watching Gooner porn. Your eyes were rolling into the back of your head, and you were stroking your cock. I have decided to enslave you. Being your step-sister means you have no way of escaping me. You will now belong to me. I will use you whenever I please. You will be made to play with your cock, whenever I want you to, I do not care if you are exhausted. I will mindfuck you, invade your brain and make your body into my favourite toy. I will mesmerize you into repeating mantras. My body makes you so weak, and so very desperate. My tits, my ass, voice and face are all triggers, my secret destructive powers. Your personality will fade; your brain cells will be erased. All of your life will be controlled by me. I know this isn’t the step-brother/step-sister relationship you thought you would have, but you didn’t know who you were dealing with.
