On a lazy Christmas day, I was lying in bed when I noticed my stepmother walking towards me, her hands exploring her curves. I was taken aback when she suddenly reached down and began pleasuring herself with her fingers. I was caught off guard as she continued to ride out her own pleasure, her body moving rhythmically against the bed. The sight of her, a curvy blonde MILF with a big, fat ass, was too much to resist. I found myself joining in, my own hands exploring her body as she continued to ride out her own pleasure. The sensation of her body against mine was intoxicating, and I couldn't help but lose myself in the moment. As she reached her climax, I felt a sense of satisfaction wash over me, knowing that I had helped her reach that peak. It was a moment I would never forget, a perfect way to end a perfect Christmas day.
