I'm your step-sister and ever since we met, I've always acted innocent and introverted. One day you try to encourage me to come to a party with you, but I decline. You leave and then I say, "well since step-mom and step-dad are gone for a week, I think I have to show him I’m not that innocent." Then I prepare everything, dress up and hide behind the door. When you come back and close it, I gag you and whisper dominantly in your ear, toying with you like never before. You moan through my hand, eventually slipping away and losing control. You wake up tied up, blindfolded and have headphones on, so that all your senses are covered. My phone is connected to the headphones and I say, “good morning, remember to listen to me. You have something that I want, and you're going to make this easy for me. It goes silent, and you don’t know where I am. I quietly walk up hovering one hand over your mouth, and the other slowly jerking you. Before you make a sound, I handgag you and then crawl on top of you. I take off the headphones and say, "I guess stealing your cum is gonna be easier than I thought." You beg me to let you go, so I shut you up with a piece of duct tape. I start riding and kissing you, convincing you I don’t have a mask on. "Since you've been obedient, I guess I’ll let you see my face," I tease as I put on my mask. I slowly take off the blindfold, but at the same time I say, "but it’d be foolish of me to let my hostage see who I actually am, wouldn't it?” as you catch a glimpse of my masked face. Then I make you cum hard. You wake up as if it were a dream, and see me sitting there in a shower robe and towel over my head as if I just finished showering. You tell me about your dream, and I want to know more. As you tell me what happened, I strip off the towel/robe without you noticing. After you finish, I giggle and push you onto the bed, handgag me and say, "I just think it's funny that what that burglar wore in your dream sounds exactly like what I’m wearing." Your eyes widen, and now you know it was real. I tape your mouth shut, and put my mask back on. "I hope you're ready for round 2. I have so much more I want to do to you. Guess I'm not so innocent after all, am I?" I blindfold you and say, “I forgot one more thing.” As you slowly fall deeper into a state of mindlessness, I say, "that's a good boy. Don't worry, your stepsis is going to take good care of you. Sweet dreams"
