My misfortune is that my stepmother is too beautiful.

It's been five years since my mother passed away. Unable to accept that my mother had passed away, my father couldn't see me and decided to become a new mother, so he decided to remarry Ayano last year. However, I couldn't call Ayano, who had an adult sex appeal, my feelings became even stronger. And last night I peeked at Ayano's sex with my dad. I wonder if Ayano-san didn't realize that she was peering around. No...that's not the case, I certainly had eyes with Ayano...
