Of course she's doing laundry now. I just got home and the little brat is on her knees in front of the washing machine, wearing that tight bodysuit that leaves fuck-all to the imagination. She asked me ten minutes ago if I had any more clothes for her. Now she's bent over, ass in the air, pretending to be real focused on sorting socks. She thinks she's so clever, but she's obviously trying to get my attention like some bratty tease. I walk up behind her and put my hand on her lower back. She flinches, but she doesn't move away. "You've been down there a while, sis. You looking for something? Or are you just putting on a show for me?" I get down behind her, pressing my crotch against her ass. "This is what you wanted, isn't it? You want to play housewife for your brother?" She lets out a fake gasp and tries to squirm away, but she doesn't put any real effort into it. "Stop it! I'm just doing the laundry," she whines. I grab her hips to hold her still. "Yeah, you're doing something. You've been bent over this machine for ten minutes waiting for me to come see the show." My hands slide down over the thin fabric of her bodysuit. "Don't... please..." she whispers, but she pushes her ass back against me. "That's not what your body is saying," I tell her, pulling the crotch of her bodysuit aside. I can feel her pushing her ass against my dick. "Do you want to make your brother hard? Do you want to submit to your brother? Is that all you're good for?" I ask, my voice low and mocking. She continues grinding her ass into my crotch with a desperate little moan. "Yes," she breathes out. "Oh wow, sis, are you okay?" I say, my tone shifting to one of fake concern laced with cruel amusement. "How horny are you right now? You're fucking dripping for it, aren't you?" "Please," she whimpers, arching her back even more. "Please what? Tell me what a slut you are for your own brother." "I'm a slut," she gasps, forcing herself back against me again. "I just want to be used. I want you to treat me like an object." "An object? That's all you've ever been," I tell her, finally freeing my cock and pressing the head against her. "A warm hole for me to use when I'm bored." I push into her in one rough, deep stroke. She cries out, a sharp, genuine sound that gets swallowed by the churning machine. "Look at you," I grunt, setting a punishing rhythm, my hands gripping her hips hard enough to bruise. "My bratty little sister, begging to be fucked by her brother. Tell me again what you want." "Don't stop!" she screams, her voice cracking as she meets every thrust. "Use me! Just use your stupid slut sister!" "That's better, this is your real job now. Being my personal fleshlight."
