Kotori was asked by her father, who deeply cared for her, to visit an elderly neighbor's house. Her father simply said, "That man is important, so you must obey everything he says," and sent her off. The man was a pervert obsessed with cunnilingus, who used seductive words to confuse Kotori and toyed with her untouched body using his foul-tasting tongue and cock. Still unaware of pleasure, Kotori followed the man's instructions helplessly, letting him do as he pleased.
