Yuka and Go were a happily married couple. One day, Go's NTR fetish was exposed to Yuka, after which she began avoiding him. However, later on, Go is surprised with a birthday celebration. It turns out Yuka hadn't been avoiding him at all—she had been secretly planning a birthday surprise. Relieved, Go feels reassured. Yuka says, "I'm sure you'll enjoy this..." and shows him a video. The video is a realistic cuckold tape showing Yuka having creampie sex with a strange man.
