Day 5 Stepsister Watching Porn and didn't Notice me Entering her Room... I Fuck her until Cum inside

Day 5: Her stepsister was always a bit of a wild one, but today she took it to a whole new level. I walked into her room, and there she was, watching porn on her computer, totally engrossed. I couldn't believe my eyes, but I couldn't look away. She's a 60fps beauty, with a big-ass and a Brunette mane that cascades down her shoulders. She's a genuine amateur, a real babe, but she's not just any babe, she's my stepsister.

As I watched her, I couldn't help but get a little excited. She was a petite teenager, only 18 years old, but she had a big-dick of a personality. I couldn't believe she was watching porn like this, and I couldn't believe how much I wanted to join in. She was into it, her body moving in rhythm with the porn she was watching, her big tits bouncing gently.

I decided to make my presence known, and she jumped, startled. But I saw the spark in her eyes, the way she bit her lip. She knew I was watching, and she liked it. I approached her, my heart pounding. She looked up at me, her big-ass perched on the edge of her bed, and she asked, "What are you doing here?"

I didn't answer. I just reached out and touched her, feeling the heat of her skin. She gasped, her eyes widening. I told her to turn around, and she did, her big-ass swaying gently. I undressed her, my hands feeling every curve of her body. She was mine, and I fucked her until I couldn't hold back anymore. I fucked her in the cowgirl riding position, her big-ass bouncing up and down on my big-dick. She moaned, her head thrown back, her big tits swaying. I felt her tighten around me, her body trembling as she came.

But I wasn't done. I flipped her over, her big-ass in the air, and I fucked her in the doggystyle position. She was amazing, her big-ass taking every inch of me. I couldn't hold back anymore, and I came, filling her with my cum. She moaned, her body trembling as she came again, her big-ass taking every drop.

It was a day I'll never forget. A day when my stepsister and I broke all the rules. A day when I fucked her until I came inside her, filling her with my cum. It was a day of pure, unadulterated lust, and it was amazing.
