My wife is giving birth next week. However, in this day and age, it was difficult to give birth at home, and the husband and wife were taken care of by her sister-in-law's house who lived near her. Her sister-in-law is kind and beautiful enough for her big brother. …he looked happy. But the reality was different. Her azoospermia was discovered when her sister-in-law, who was not blessed with a child despite her waiting, had her older brother undergo an examination. Witnessing her sister-in-law who was stricken by her despair, I was lustful.
