I was shocked to find a schoolgirl sleeping on the sofa when I got home! Her long, slender legs were stretched out, and her skirt was flipped up, revealing her white panties. I was even more shocked when she woke up and called me "Big Brother!" It turns out my parents remarried, and she was my new stepsister. From then on, life became chaotic as she tried to seduce me at every opportunity! Eventually, I couldn't resist and fucked her pussy!
