Hidden camera captures stepmom's skirt teasing my hardening cock

I stumbled upon a hidden camera in my stepmom's room, and to my surprise, it had been capturing her in some rather compromising positions. As I was going through the footage, I came across a clip where she was wearing a short skirt, and I could see her round ass bouncing up and down as she moved around. It was clear that she was trying to tease me with her seductive moves, and it was working. My cock started to harden as I watched her, and I couldn't help but imagine what it would be like to fuck her. I've always been a big fan of big asses, and her ass was definitely on the bigger side. I couldn't resist the urge to touch myself, and I started giving her a little show as I stroked my cock. The sight of her on her knees, fucking me with her tight ass, was enough to make me cum all over the place.
