ADN-016 Perverted brother-in-law raped sister-in-law while brother was away

When I was young, my mother left home for another man. My father cried every night, which made me very sad.

However, I still behaved normally at school so that people wouldn't find out about my family's affairs. A few years later, my father remarried, and I had a new family, a gentle and kind mother, and a sister who was a bit addicted to games. I was really happy.

A few years later, I left my hometown and went to study at a university in Tokyo. Because it was the first time I had to live alone, my father was very worried, but he was also very proud of me. My mother was too, which made me the happiest. But just a few years later, my father passed away. Today is my father's birthday, so I returned to my hometown.
