I've always had a thing for my step-sister. She's got this irresistible allure that's hard to ignore. She's not just hot, but she's got this naughty side to her that's just as appealing. I've been trying to resist the urge, but it's becoming increasingly difficult. Every time I see her, I can't help but think about what it would be like to be with her. I know it's wrong, but I can't help it. I've been fantasizing about her, and I've finally decided to act on my desires. I went to her room the other day, and we got down and dirty. It was everything I had imagined it would be. She's a wild one, and I loved every second of it. I can't wait to do it again.
