Matsumiya, who was attending a university in Tokyo, received a call that her mother, who she had left behind in the countryside, had collapsed, so she hurried home, but she found a group of old men hungry for young women waiting for her. She was threatened and forced to give a blowjob, and was forced to give a facial, and was made to satisfy the men's pent-up sexual urges, but on the other hand, she used the techniques she had learned in the city to please the men and climaxed herself, turning her into a naturally lewd woman.
