YAG-023 Ogawa Nano (Ogawa Nano) Yabai Imouto: Humiliation Yabusame (ei Ten)

Today, my mom was late coming home again, so I took my sister out to play. Since my father has been away for a while, I've been taking care of my little sister in my mother's place, watching over her every day. I've come to realize that I know her growth and needs better than her own mother. Today, I drove us to a quiet mountain road. I made her wear a coat and put the leash on her collar, letting her walk like a pet. When Nano said she wanted to go potty, I let her squat down and relieve herself like a dog.
