I had to visit my 'sister' in her room, and when I got there, I couldn't resist the urge to get down and dirty with her. She wasn't my sister, but that didn't stop me from treating her like one. I started by teasing her, running my hands over her body, feeling her curves through her clothes. Then, I began to undress her, revealing her perfect figure. She was moaning and writhing in pleasure as I touched her, and I could tell she wanted me just as much as I wanted her. I took her to the bed and began to fuck her, thrusting into her with wild abandon. She was screaming in pleasure, her body convulsing under mine as I brought her to orgasm after orgasm. It was the hottest thing I've ever done, and I can't wait to do it again.
