I didn't Close the Door to my Room and my Big Tit Step Sis came in

I didn't close the door to my room and my big-titted step sis came in, and my life took a wild turn. I was innocently lounging on my bed, lost in my thoughts, when she sauntered in, her massive rack practically exploding out of her tight top. I was taken aback, but the sight of her was too much to resist. She looked at me with a mix of desire and mischief, and I knew she wasn't there just to chat.

The room was filled with a tense, electric energy as she closed the door behind her, locking the world out. She began to undress, her eyes never leaving mine, her breath growing heavier as she revealed her luscious curves. I watched, spellbound, as she revealed her massive, natural tits, her nipples already hard and begging to be touched.

I couldn't believe what was happening. My step-sis, with her big, juicy ass and massive tits, was standing in front of me, ready and eager. She didn't need to say a word, her body was doing all the talking. She crawled onto the bed, her big, firm ass swaying with each movement, and straddled me. I felt her hot, wet pussy against my hard cock, and it was all I could do not to explode.

She started to grind against me, her big tits bouncing and swaying with each movement. I could feel her wetness soaking through my jeans, and it was driving me crazy. She leaned down, her big tits pressing against my chest, and whispered in my ear, "I want you to fuck me, little brother."

I was in heaven. I flipped her over, my big dick ready to explore her tight, wet pussy. I pushed it in, her eyes rolling back as she moaned in pleasure. I began to fuck her hard and rough, her big tits bouncing with each thrust. She was moaning and screaming, begging for more.

The room was filled with the sounds of her moans and my grunts, our bodies slapping against each other. I could feel her getting closer, her pussy tightening around my cock. I wanted to make her come, to see her scream my name.

She reached her peak, her body convulsing as she came, her pussy pulsing around my cock. I couldn't hold back any longer, I pulled out, my big dick erupting with ropes of hot cum, painting her stomach and big tits.

As we lay there, panting and sweaty, I knew this wasn't the end. My step-sis was a wild card, and I was ready for whatever she had in store. The door wasn't closed, but the world outside was a million miles away.
