As I sat in the bath, I couldn't help but feel eyes on me. I glanced over my shoulder to see my stepsister, Emily, watching me intently from the doorway. She had grown into a stunning young woman and her tight curves pressed against her clothes left little to the imagination. "Do you need something, Em?" I asked, trying to sound casual. She smiled and stepped into the bathroom, her gaze locked on my rising cock. "I saw that you had a package delivered today," she said, her voice quivering slightly. "I was wondering if maybe... you wouldn't mind sharing it with me?" I swallowed hard, my heart racing in my chest. This was the moment I had been dreaming about for years. I nodded, my throat too dry to speak. Emily knelt down in front of me, her soft hands wrapping around my cock as she gently e xpressed concern for my wellbeing.
