When I Returned Home, I Found That My Grandfather And Mother Were Having Sex. What I Saw That Day Changed Me Into A "mature Woman Lover" For The Rest Of My Life. Momoko Isshiki

It's been five years since I left my hometown to live in Tokyo, and I've come back home for the first time in a while. My parents and grandfather live in the family home. Since my grandmother passed away, my mother has been caring for my grandfather, who is depressed and mostly bedridden. My father has no interest in the family and is always out and about. Then one day, a strange sound leaked from my grandfather's room. It sounded like the cry of an animal in heat. Curious, I quietly slid open the shoji screen. And there... in the room was my mother, vulgar, moaning as my grandfather greedily sucked her breasts while lovingly fondling his own cock.
