When I woke up in the morning, I had the body of an adult ~ A lewd adult body, a day's experience ~

One morning, Mizuki wakes up to find that her body has become a dynamite body. However, Mizuki, who wanted to become an adult as soon as possible, was delighted and said, ``It's like becoming a mother!'' Then, she tries her best to do housework, saying, ``Starting today, I'll take the place of my dead mother!'' However, her brother deceives her, saying, ``This is also mother's work,'' and forces her to do obscene things.
