ABP-026 The curious son about sex and the outcome

When I was young, my mother left home for another man. My father cried every night, which made me very sad. Nonetheless, I still behaved normally at school so that everyone wouldn't find out about my family's situation. A few years later, my father remarried, and I gained a new family, a gentle and kind mother, and a slightly gaming-obsessed older sister. I truly felt very happy. A few years later, I left my hometown to study at a university in Tokyo. Since it was my first time living alone, my father was very worried, but he was also very proud of me.
