[SEMC-004] I laid hands on my only niece. (Censored)

My niece was lonely without siblings, and since she was a child she was more attached to me, her uncle, than her parents. I often took her out to play and gave her pocket money. We even took a bath together. Of course we didn't take baths, but our relationship didn't change even after we became adults, and from the time she entered high school, I started to think of her as a woman. We hadn't had many opportunities to meet recently, but my parents invited me to dinner while they were on a trip. She seemed lonely, as she had recently broken up with her boyfriend. On the way home, I hugged her in a drunken state, but she didn't seem to mind, and we naturally kissed each other. Before I knew it, we were naked and embracing each other in a hotel room.
