Yukako was cleaning while shaking her breasts and plump belly. "Have I gained weight recently?" I muttered while touching my sweaty belly. My son, Shinji, who was looking at me, came up to me and said, "It's better to be healthy and warm than to be thin." I started touching Yukako's belly. For a while, Shinji rubbed her belly and buried her face, taking care of Yukako.
