I Found Out that My Stepsister is Doing Porn

As I watched my stepsister Mia, I couldn't believe my eyes. There she was, on my laptop screen, performing in a porn video. The video showed her being pleasured by a man whose face was blurred out. My heart raced as I struggled to control my arousal.I made a decision. I had to confront her about this. Tomorrow, at the breakfast table, I would bring it up. My cock throbbed in anticipation of the confrontation as well as the possibility of seeing more of my stepsister's body.The next morning, I waited for Mia to sit down before broaching the subject. She took a sip of her coffee before looking at me."Yes, Alex?" She asked innocently."Mia, I need to talk to you about something," I said, trying to sound casual, but my voice betrayed my nervous Mia looked up from her book and met my gaze, her eyebrows furrowed in confusion."What is it, James? You're acting really strange."
