A married woman comes to the gym to lose weight. Gym trainer Yoshida loves boobs more than food, and even though he thinks "You shouldn't look!", he can't help but stare at the married woman's breasts... As the married woman changes into her sportswear, Yoshida, while erect, teaches her stretching, muscle training, and the aerobic bike. Before she knows it, the married woman is covered in sweat, and her sportswear becomes so transparent that there is no point in her wearing it anymore...
