I was living in the dormitory at school and came back home during a long holiday. My parents and grandfather live at home. My grandmother died a year ago, and my mother has been taking care of my grandfather who was shocked and bedridden. As for my father, he doesn't care about the family and is always out and about. One evening, I heard strange noises coming from my grandfather's room. Had a stray cat gotten in? It sounded like that. Curious, I quietly slid open the shoji door. And then... inside the room was my mother in a vulgar pose, sucking on my grandfather's breast while lovingly stroking his dick.
