My wife and I live next door to my wife's parents in an apartment building. My mother-in-law, Aki, is very pretty and beautiful, and I still get excited when we eat together. Maybe that's why I haven't had sex with my wife recently. She wants to have children, so she wants to, but I'm not sure... One day, my father-in-law got injured at work, and his younger brother, who works with him, came home carrying him. There, I found the aphrodisiac that my father-in-law was taking, and after asking him about it, I found out that he had been having sex with Aki, who seemed a little frustrated, almost forcibly.
