I left my hometown to live in a university dorm and used the break to return home for the first time in a while. My parents and grandfather live at home. After grandmother passed away, grandfather became depressed and half-bedridden, so mom takes care of him. Dad has no interest in the family and is always out. One day, a strange voice leaked from my grandfather's room. It was unmistakably the sound of a woman moaning. Curious, I quietly opened the sliding door and saw… inside the room, my mother was having her breasts sucked while she lovingly stroked my grandfather's dick.
