My Stepsister Asks me to Fuck her before going to Bed while her Husband is at Work

My heart was pounding like a drum as my gorgeous stepsister, the 18-year-old Russian beauty with a blonde mane and a body to die for, walked into my room. Her husband was out of town, and she couldn't wait to break her no-strings-attached rule. I could almost feel the electricity in the air as she whispered, "I need you to fuck me before I go to bed tonight." I was in shock, but my cock was already standing at attention, ready for the action. She was a hot step-sis, and I couldn't resist the temptation. We started with a passionate kiss, our tongues dancing in a intimate dance. Then, she dropped to her knees, her big blue eyes looking up at me as she opened her mouth wide, welcoming my big dick into her hot, wet mouth. She sucked me off like a pro, her head bobbing up and down, her lips tight around my shaft. I could feel myself getting closer to the edge, but I knew I had to hold off. We switched positions, moving into a reverse cowgirl, her tight pussy sliding up and down on my cock. I could feel her every inch of her, her big ass bouncing as she rode me. She was moaning loudly, her voice filled with pleasure, and I knew I had to make her cum. I turned her around, putting her in a doggystyle position, and I slammed into her, her big ass taking every inch of my cock. I could feel her getting tighter, her body shaking as she reached her climax. I pulled out, my cock ready to explode, and I shot my load all over her face, her tits, and her blonde hair. She licked it up, her eyes filled with satisfaction. It was a night neither of us would ever forget.
