Petite sis helps stepbrother with his big cock problem

I caught my stepbrother pleasuring himself with my favorite toy, and I couldn't resist joining in. As an 18-year-old with a wild side, I knew I had to help him out. His big cock was just too enticing to ignore. I'm not your average innocent sister; I'm a horny teen who knows what she wants. I gave him a mind-blowing blowjob, taking his entire length down my throat. Then, I mounted him in cowgirl, riding him hard and fast. The sight of his thick cock pounding into me was enough to make me lose control. We switched it up, and he took me from the front in missionary, driving deeper and harder. Finally, we finished off in doggystyle, both of us completely satisfied. It was a wild ride, and I can't wait for the next time we get caught together.
