Young stepsister discovered pleasuring herself on my mattress

As I strolled into my room, I noticed a peculiar sight on my bed. My stepsister, a young, cute, and petite student, was lost in a world of pleasure, her hands exploring the depths of her desire. The sight of her, nestled on my bed, her petite frame adorned in wet panties, was a tantalizing one. I couldn't help but be drawn to the erotic scene unfolding before me. As I watched, I realized this wasn't my sister, but a hot stepsister, a seductive vixen who knew how to play the game. Her delicate fingers moved rhythmically, her body trembling with each touch. The sight of her wet panties, glistening under the soft light, was a testament to her arousal. I found myself drawn to her, the sight of her pleasure too much to resist. But as quickly as it started, it ended. She caught my gaze, our eyes locking briefly before she hurriedly got dressed and left. The room fell silent, the only evidence of her visit were the damp imprints on my bed.
