[Reducing Mosaic]ADN-366 I have to have unprotected sex with my sister-in-law on her fertile days as a substitute for my broke and impotent brother. Akari Tsugumi.

My wife is giving birth next week. However, in this day and age, it was difficult to give birth at home, and the couple decided to take care of 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.
