Playing with my innocent stepdaughter on the sofa - Teen self-pleasure

I was lounging on the couch with my stepdaughter, discussing her upcoming plans for college and her dreams of becoming a nurse, when I couldn't resist the urge to play with her cute little body. Despite her innocent facade, I had a sneaking suspicion that she was hiding something beneath her clothes. I gently lifted her skirt, revealing her smooth, untouched thighs, and began to tease her with my fingers. As I continued to explore her body, I noticed a hint of wetness between her legs, which only fueled my desire to discover what other secrets she might be harboring. I guided her to a nearby mirror, where she eagerly indulged in her own pleasure, her small hands skillfully stroking her delicate folds until she reached a powerful climax, leaving a trail of warm, sticky evidence on the mirror's surface.
