At 26, I work as a company employee and have married my senior at work. My wife is a divorced woman slightly older than me, raising her only daughter named Hikari. The girl is affectionate and full of energy, which made my wife warmly accept me. After we started living together as a family of three, Hikari became even more attached, clinging to me like she was making up for the fatherless days of her past. As our happy life continued, one day Hikari accidentally witnessed my intimate moments with her mother. From that day on, she seemed to awaken to something new, beginning to show a special interest only in me—drawing closer and desiring me more intensely.
