My mother passed away before I could even remember her. It was just my father and I living together ever since. I can never thank him enough for everything he has done for us. One day, my father remarried a beautiful woman named Yui. She was so young and attractive that I couldn't help but feel nervous around her. Every night, she would have passionate sex with my father, their moans echoing through the hallway outside our room. Their intense lust was too much for me to handle; it felt like a constant provocation.
