Dangerous Sister Nano Ogawa

Today, Mom called to say she'd be coming home late again, so I took my younger sister Nano out to play. Because of our age difference, I've always been the one looking after her while Mom is at work, so I know more about her development than Mom does. As usual, I drove us to a quiet mountain road where I stripped Nano naked, put a coat on her, fastened a collar around her neck, and took her for a walk like a pet. But when she suddenly said she needed to pee, I let her go right there, just like a dog.
