Two years into our marriage, I love Shiori but we've fallen into a rut. I confessed my desire for her to be taken by another man, but she rejected me… So I encouraged my younger brother, who has feelings for Shiori, to seduce her and set up hidden cameras to spy on them during his business trip. What started as a game turned into something more when I saw the expression of guilt and pleasure on my wife's face as another man penetrated her. However, watching them genuinely fall for each other and connect left me anxious, but it was too late… All I could do was watch helplessly as my wife became his in just three days.
