Russian teen stepsister exercises on an elliptical machine with a large penis

I had always been a bit of a voyeur, but this time, I went too far. When my stepsister came to my place, I was working out on the elliptical machine. She noticed my big cock and decided to give it a try. At first, she seemed a bit hesitant, but then she took me in her mouth and started sucking like a pro. The sight of her on her knees in front of me, her tight pussy exposed, was too much for me to resist. I pushed her against the machine, fucking her hard and deep from behind. The sensation of her tight hole around my monster cock was indescribable. It was a sight to behold as she took every inch of me, her petite body bouncing up and down on the machine as I ravished her. It was a wild ride, but one that I wouldn't trade for anything.
