ROE-544 When I went home, my grandfather and mother were having sex. That day's incident turned me into a lifelong 「mature woman lover」―. Inamori Masaru.

I left my hometown to live in Tokyo and used my time off to return home for the first time in a while. My parents and grandfather live at home. After grandmother passed away, grandfather has been half-bedridden due to grief, and mom is taking care of him. Dad doesn't care about the family and is always out. One day, a strange voice leaked from my grandfather's room. It was unmistakably the sound of a woman moaning. Curious, I quietly opened the sliding door to see… Inside the room, my mother was having her breasts sucked and lovingly jerking off my grandfather.
