[Iwai] Kataomoi Osananajimi to Kozukuri Suru Koto ni Narimashita

Kinoko-making sex.. It feels so good that I can't think of anything else—Kiyohana is the only daughter of a long-established Japanese confectionery store. I like my childhood friend Yushi.. but due to a certain system in the country, I couldn't freely choose a marriage partner, so I was keeping a lid on my feelings. However, the person who was fatefully matched with a tremendous probability was Yushi..!? A trial cohabitation life that begins that day. After a long-standing love affair, Seika forcibly invited him to confirm the compatibility of the night..! It feels completely different from touching it myself, and I feel so convulsive that even my toes cramp..? An exciting child-making life between lovers who can't be honest.
