After a night out, my young stepsister gets a rough punishment in my dorm room

After a wild night out, my young stepsister found herself in a bit of hot water. She had been drinking heavily and making a fool of herself, all captured on camera by some of my frat brothers. It was a holiday, and I had invited her over to party with us, but things had gotten out of hand. When she stumbled back to my dorm room, I knew I had to teach her a lesson she wouldn't forget. Despite her protests, I took control, using her own embarrassment against her. I stripped her down and showed her the footage, watching as she squirmed in humiliation. But as it turned out, she wasn't the only one with a dirty secret. I revealed a video of myself pleasuring myself with her picture, which only seemed to arouse her. The rest, well, let's just say it was a rough ride for both of us.
