Living next door to us in the apartment complex are my wife's parents. My mother-in-law, Aki-san, is very beautiful and still makes my heart race when we eat together. Perhaps because of this, my wife and I haven't been intimate recently, even though she wants a child. Meanwhile, my father-in-law got injured at work, and his brother had to carry him home. I discovered my father-in-law's energy drink and, upon learning more from him, found out that he had been forcibly intimate with the somewhat sexually frustrated Aki-san. I accidentally witnessed this scene while delivering something next door. Seeing Aki-san sleeping in the kotatsu, I thought it might be okay to touch her a little, remembering the incident with her and my father-in-law's brother. When she woke up, I hugged her as if covering her, and confessed all my feelings to her. After that, I secretly indulged in intimacy with Aki-san behind my wife's back. However, it was impossible for my wife not to find out about this relationship...
