Caught in the Act: Brother walks in on stepsister in the middle of a solo session with adult content

It was a typical evening at home, and the house was relatively quiet. My sister, Rachel, was in her room watching a movie, and I was in the living room playing video games. Suddenly, I heard a loud moan coming from Rachel’s room. I tried to ignore it, but it persisted, and I got curious. I quietly walked to her door and peeked inside. I was shocked to see Rachel on her bed, naked, and watching an adult video. I was about to leave, but Rachel spotted me and asked me to stay. She explained that she was watching the video to learn more about her body. I couldn’t believe it, but I stayed and watched with her. And that’s how I learned everything I needed to know about female anatomy.
