[Reducing Mosaic]NAIAD-007 AI Live-Action: The Dangerously Inappropriate Photos of My Stepdad and Sister

【Finally, AI in live-action! Just like the atmosphere!】This is a story from last summer when I went back to my hometown during university break. Our family consists of my mom, me, my sister, and my stepfather who remarried a few years ago, making us a family of four. The thing that surprised me the most upon returning home was how much my sister had developed. She had grown taller, her chest had become larger, and she had grown more feminine than I had imagined, which made me quite nervous. After taking a bath, wearing just a towel like that is way too careless. As a virgin with no experience, I was really flustered w her ass, it was in such a great shape… so… this is the main point? Bored at home, I thought I'd work on my seminar assignment and borrowed an old-looking laptop from my stepfather's room. Thinking back now, he must have been hiding something. And that's how I accidentally found it.
