Came into my Stepsister's Room at Night

As I tiptoed into my stepsister's room, I could barely contain my excitement. She was fast asleep, her big, round ass perfectly outlined by the thin silk of her nightie. I couldn't help but wonder what she'd look like without it. As I inched closer, I felt her warmth, her soft breaths tickling my cheek. I was in for a treat. Her tight, little pussy was clenched shut, just waiting for my big dick. I knew it would be a tight fit, but I couldn't wait to fuck that sweet little cunt. I reached out and gently traced my fingers along her inner thigh, feeling her shiver with anticipation. She was already wet, I could tell. Her dark, glossy hair fell over her face, casting shadows that only made her look more enticing. I leaned in, my nose inches from her ear, and whispered, "I'm here to fuck you, little sister." She jumped, startled, but quickly realized what was happening. A wicked smile played on her lips as she turned to face me. "You're a naughty boy, aren't you?" she purred. "You're going to regret this," I teased, my heart pounding with excitement. Her eyes widened as I pulled back the covers, revealing her big, bare ass. I couldn't wait any longer. I grabbed her hips and positioned her on her hands and knees, her ass pointing straight at my eager dick. I ran my hands over her smooth skin, feeling her tremble beneath my touch. She looked back at me, her eyes filled with a mix of fear and excitement. "Be gentle," she begged, but I knew that wasn't in my nature. I thrust my big, hard cock into her tight pussy, feeling her scream as I stretched her wide open. She was a virgin, and I was her first. I knew it would hurt, but I couldn't stop myself. I pounded into her, my cock slamming against her sweet little cunt. She moaned, her fingers digging into the sheets as I ravaged her body. I grabbed her hair, pulling her head back as I fucked her from behind. She cried out, her pussy tightening around my cock as I plunged deeper and deeper inside her. I could feel her juices flowing, coating my dick as I filled her completely. I knew I was being rough, but she loved it. She loved the way I stretched her out, the way I made her feel like a dirty little slut. I could feel her pussy getting tighter and tighter, her moans getting louder and louder. I knew she was close. I reached around and rubbed her clit, feeling her body shiver as she came undone. I couldn't hold back any longer. I felt my own orgasm building, and I knew I was going to fill her sweet little pussy with my hot cum. I thrust deeper and deeper, my body shaking as I released inside her. As we both collapsed onto the bed, I couldn't help but think about how much I loved fucking my stepsister. She was so tight, so sweet, and so fucking sexy. I knew this was just the beginning of our little game. I was already looking forward to the next time I could sneak into her room and make her mine.
