Netoraserare, Volume 1 (English, Paperback, Shikishiro Konomi)

After two years of marriage, Shuujirou and Haruka shared a marital lifestyle anyone would be jealous of. To outside observers, they seemed so happy together and had the perfect marriage. However, behind closed doors, Shuujirou's sex drive has stalled and Haruka doesn't know what she can do. One day, a twisted desire comes bubbling to the surface that shocks Haruka to her core as Shuujirou utters these words, begging on the floor: "I want you to sleep with another man."
