Mai, who entered the household as the second wife, lived happily, but her only problem was that she could not open up to her son-in-law, Fuuta. It is difficult for her to become a mother of adolescent boys. She was prepared for it, but she didn't think she could even hold a conversation... One day, Mai, who is worried about her, takes an outrageous action to shorten the distance between her. Naked socializing is the best way to open up to her. That's what she thinks. Mai bursts into the bathroom naked while Fuuta is taking a bath. However, this action causes her forbidden desires, which Fuuta has hidden in her, to go out of control.
