My mother's friend Sumire visited my house and my son Shosuke was completely fascinated by her neat beauty. He is nervous and can't speak well, so he takes the joke seriously and unintentionally exchanges a passionate kiss. In the middle of the night, when Sumire is unable to sleep because of the excitement of a young man's kiss, Shosuke visits her... While telling each other that it was only for tonight, they piled their bodies on top of each other. However, the young man's libido could not be satisfied with that, and Shosuke sneaked into her room the next day.
