Beast Brother’s Bathroom Domination with Sexy Sister

I watched my step-sister bend over the bathroom sink, her tight skirt riding up her thighs. The steam from the shower made her skin glisten, and I couldn’t resist stepping closer. She gasped when my hands gripped her hips, but she didn’t pull away. I pressed my hard cock against her ass, feeling her tense up as I whispered in her ear, ‘You know you want this.’ She whimpered, and that was all the consent I needed. I pulled down her panties and slid into her wet pussy from behind, fucking her hard against the marble counter. Her moans echoed off the tiles as I pounded into her, my balls slapping against her clit with every thrust.

She braced herself on the sink, her tits bouncing as I fucked her deeper. I reached around to pinch her nipples, making her cry out. ‘Fuck, you’re so tight,’ I grunted, pumping into her faster. The sound of our bodies slapping together filled the bathroom. I could see her face in the mirror, her lips parted, eyes half-closed in ecstasy. She was loving every inch of my dick inside her. I pulled out and spun her around, lifting her onto the counter. She wrapped her legs around my waist as I shoved my cock back into her, fucking her missionary style. Her nails dug into my back as she came, her pussy clenching around me.

I didn’t stop, pounding her through her orgasm until I felt my own building. I pulled out and shot my load all over her stomach, watching my cum drip down her skin. She looked up at me with a satisfied smirk, then slid off the counter and knelt in front of me. She took my still-hard cock in her mouth, licking off the remnants of her own juices. I grabbed her hair and fucked her face, using her throat until I was spent. She swallowed every drop, then looked up at me with those innocent eyes. We both knew this wasn’t the last time.
