I work in Tokyo and used my days off to return home for the first time in a while. My parents and grandfather live at home. Since grandmother passed away, grandfather has been depressed and half-bedridden, with mother taking care of him. Father has no interest in the family and is always out. One day, a strange sound leaked from my grandfather's room. It sounded like the roar of an extremely aroused beast. Curious, I quietly opened the sliding door to take a look. And then… inside the room, there was my mother gasping as she had her breasts sucked by my grandfather, while he lovingly played with his own dick.
