MIMK-090 Niece and Time-Killing - Live-Action Version - Yagi Nana

Originally, my niece was very close to me. Perhaps it's because her parents were busy and often brought her to my house nearby. As she neared the time for school entrance, I felt her growing up. From that point on, I started seeing her as a woman. During spring break, my niece watched porn on my smartphone. It was bad, but... my niece, who had become interested in sex, and I crossed the line. To pass the time, I made her squirt with hand jobs, made her cum with toys, and even had sex without a condom. Neither of us have romantic feelings; we're just continuing our physical relationship out of interest.
