It's been eight years since I married Saki. Because I'm a workaholic, I haven't been able to give her enough attention, and our relationship has gradually grown distant, becoming awkward between us. Lately, I noticed she's always on her phone. I wondered if there was something so important she had to keep checking it. On a whim, while Saki was asleep, I snuck a peek at her phone. Among the many pictures saved in her album, I found some revealing and obscene photos of my wife. They were filled with Saki's "hidden side" that I didn't want to know about... Saki, whose mature body was devoured by a stranger, reached a climax that I, her husband, had never seen before. The shock of being betrayed by my wife was surpassed by the excitement of having her taken by another man.
