It's been eight years since I married Saki. Because I was a workaholic, I wasn't able to pay her enough attention, and our relationship gradually grew distant and it became awkward. Recently, I noticed that my wife was always fiddling with her smartphone. I wondered if there was something she was so curious about that she needed to look at. On a whim, I took a peek at Saki's smartphone while she was sleeping. Among the many images saved in the album, I found some naked and lewd erotic images of my wife. They were filled with images of Saki's "other side" that I didn't want to know about... Her ripe body was devoured by a stranger, and Saki reached an orgasm I, as her husband, had never seen before... The excitement of having my wife cuckolded exceeded the shock of being betrayed by my wife.
