It's been five years since I left my parents' house and moved to Tokyo, and I've finally returned home. My parents and grandfather live in my home. My grandmother passed away, and my grandfather is depressed and half-bedridden, so my mother is caring for him. My father has no interest in family life and is always out and about. Then, one day, I heard a strange voice coming from my grandfather's room.
It sounded like an exaggerated animal noise. Curious, I quietly opened the sliding screen door. And there I was...inside the room, my mother was moaning as my grandfather devoured her breasts, while my grandfather lovingly played with his penis.
