Riku-chan is a sports-oriented girl who belongs to the girls' soccer club. She hasn't had a boyfriend in two years and has become quite distant from sexual matters in her daily life. However, youthful sexual desires aren't so easily suppressed. Once unleashed, Riku-chan starts sweet-talking for Yoshi-chan's sake. In reality, she seeks pleasure by accepting the penis of an old man who is more than 20 years older than her.
