My sister and I were alone since we were little... We lived far away from civilization, but that was okay. At least we had each other. Our useless uncle was our only relative, but he couldn't do anything... He wasn't worth anything. That's why it felt safe... But then everything went wrong. I poured all my love into my sister. Yes, she would be mine, without anyone interfering. I swore to make her completely mine, no matter what. So I never wanted her to perform fellatio on me... But she betrayed me in this unexpected way. I became so angry that I wanted to kill her, and at the same time, I got incredibly aroused... It was the most exciting thing as a living being. How low will I have to sink to get rewarded? *Note: Content may vary depending on the recording method.
