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...
