My husband and I and my wife's parents live next to each other in an apartment. - My mother-in-law, Aki, is so pretty and beautiful that I still get excited when we eat together. - Maybe that's why my wife and I haven't had sex lately, and she wants to have a child, so I guess she wants to, but I just don't feel like it...At that time, my father-in-law got injured at work, so we had to go together. - My father-in-law's younger brother, who works, came home carrying it. - There, I found the stimulant that my father-in-law was taking, and when I heard various things from him, I found out that he was half-forced with Aki-san, who was feeling frustrated. - I happened to witness the scene and went next door to deliver my luggage. - The moment I saw Aki sleeping under the kotatsu, I remembered what I had done with my father-in-law's younger brother, and thought it would be okay to touch her, if only for a little bit, so I did. - When Aki woke up, I hugged her and told her my feelings. - After that, I indulged in an act with Aki-san while stealing my wife's attention. - However, there is no way that his wife will find out about this kind of relationship...
