I left my hometown and work as a salaryman in Tokyo. I used my days off to return home for the first time in a while. My parents and grandfather live at home. My grandmother passed away recently, and my mother is taking care of my grandfather who has been half-bedridden since then, depressed. My father is indifferent to the family and is just an alcoholic. One evening, I heard a strange noise coming from my grandfather's room. Was it a dog in heat that had gotten in? That kind of sound. Curious, I quietly opened the sliding door to see... Inside the room, there was my mother, happily stroking my grandfather's dick while he sucked on her tits.
