The door creaked open, and my heart leaped into my throat. I was sprawled on the bed, scrolling through my phone, when she walked in. My step-sister. She was wearing that schoolgirl outfit – short plaid skirt, white top barely containing her big tits, hair in pigtails. Total chaos.
"WTF are you doing in MY room?" she asked, her voice a mix of annoyance and...something else. I could see the flush creeping up her neck.
"Wrong room," I mumbled, trying to play it cool. But her eyes were glued to me, not the room. She stepped closer. "Liar. What's that in your hand?"
I knew I was busted. My hand instinctively tightened around myself. God, she was so fucking hot. It felt wrong, but the taboo was electrifying.
She leaned in, her big natural tits practically begging to be touched. "You're watching me?" she whispered, her breath hot against my ear. "Naughty, naughty..."
Suddenly, the anger melted away, replaced by pure desire. "What if I am?" I challenged, my voice hoarse.
She straddled me, a playful glint in her eye. “Then maybe I should give you a show you’ll never forget." She started to bounce on me, her bouncing boobs driving me wild. The bed squeaked with each thrust as she rode me like a seasoned pro. This cowgirl position was insane!
Her loud moaning filled the room. Every touch was electric, a symphony of forbidden lust. I grabbed her hips, guiding her harder, faster. Her body was perfect. We were both lost in the moment, consumed by raw passion.
I flipped her over to missionary, burying myself deep. I went harder than I ever thought I could, and felt the hotness release inside of her as I filled her with my creampie. "Oh God, yes!" she screamed, her body convulsing.
Afterward, we lay there panting, the silence thick with unspoken words. The passionate sex had changed everything. This wasn’t just a mistake; it was something real, something we both desperately wanted.
