Five years have passed since my mother passed away. Unable to accept that my mother had passed away, my father couldn't bear to see me like that, so he wanted a new mother and decided to remarry Ayano last year. However, I couldn't call Ayano, who exuded adult sexiness, my feelings became even stronger. Then last night, I peeked at my father and Ayano having sex. I wonder if Ayano didn't notice that I was peeking. No... that's not true, I definitely made eye contact with Ayano...
