Steamy Sibling Showdown

Alex trudged through the front door, his shirt glued to his chest by post-game sweat and August grime, legs like jelly after the win. Mom’s voice boomed from the kitchen speakerphone, ordering him to shower before touching anything. He grunted and hauled himself upstairs, only for the screen door to slam as Sophie strutted in, all golden limbs and swaying hips in her tiny volleyball shorts and cropped sports bra. “Nice game, Alex. Miss another layup or trip over your own dick?” she teased, faking a hip check that pinned him to the wall. “We won, and at least I don’t serve like a catapult with Parkinson’s,” he shot back. She ruffled his hair, laughing. “Oooh, burn. Still acting like you run the place after college?” Their banter echoed up the stairs, but every time she jogged ahead, her perfect ass bounced in those painted-on shorts, stirring the familiar forbidden heat he’d fought for years.

Sophie blocked the bathroom door with a smirk. “Shower’s mine. Your hair takes forever anyway.” Alex protested, but Mom’s yell cut through: the hot water heater was broken, forcing them to share or go without. Sophie shrugged, unbothered and strong as ever. “No biggie. We shared everything growing up.” Alex’s heart raced as they returned upstairs, her hips swishing dramatically. “Aw, scared to see a girl naked, baby bro?” she taunted. “I’m not scared, I just don’t want to see you naked. Like, ever,” he muttered, sweating already. She popped her head out, grinning. “Come on, or need an invitation?” He stepped in, eyes down, but caught her tossing the sports bra and shimmying off the shorts, fully naked and unashamed.

Sophie spun like a runway model, her D-cup tits perky, nipples pink, landing strip above her smooth pussy. “See something you like?” Alex turned away, neck popping. “Jesus, sis, try being normal.” She laughed, stepping into the steaming spray. “This is normal. Maybe hit the gym more.” The stall was cramped; their bodies brushed constantly, water cascading over her glistening ass. She handed him body wash. “Scrub my back, gentleman?” His hands slid over slick skin, tension building with every stroke as she arched, pressing her ass back. “Getting handsy?” she quipped, witty and bold. He lied about sand, but she grabbed his hand, smacking it onto her ass cheek. “I know you’ve stared since puberty.” His cock hardened instantly against her thigh.

Sophie spun, pinning him to the tile, tits squashing his chest, breath hot. “You ever fuck a girl?” He shook his head, horny and panting. She pressed closer, thigh grinding his hard cock. “Want to?” Without waiting, she kissed him fiercely, tongue swirling, then dropped to her knees for a wet blowjob, stroking his shaft while water dripped down her back. “You have no idea how long I’ve wanted this,” she said, pumping faster, balls cradled. He groaned, hands in her hair, the taboo thrill making him throb. She stood, guiding him between her legs, rubbing his tip against her dripping wet pussy. “Fuck me, Alex. Do it,” she commanded, strong and unyielding, jumping to wrap toned legs around his waist.

He thrust into her tight pussy, pinning her against the wall as hot water rained down, her ass cheeks spread around his cock. Sophie moaned loudly, nails digging his back. “You’re so fucking big. I knew it.” Their bodies slapped wetly, her massive tits bouncing wildly with each deep stroke. She rubbed her clit, panting, “I’m gonna cum—fill your big sister up!” Her walls clamped hard as she came, gushing around him, milking his cock until he exploded, thick cum pulsing deep inside her dripping pussy. They stayed locked, sweating and panting, juices mixing and leaking down her thighs.

After toweling off and pretending normalcy at dinner, every glance from Sophie promised more heat. “We’re definitely doing this again,” she whispered later, eyes sparkling with wicked intent. “Next time, even rougher—and maybe louder for Mom to hear.”
