A high school girl feeling unwell is taken to the infirmary. Under the watchful eyes of her classmates, she is made to urinate into a washbasin under the pretense of a urine test. Obeying the teacher's instructions without resistance, she displays a masochistic obedience. Her act of urinating while wearing bloomers fully expresses her submissive nature. Her innocent appearance and obedient demeanor highlight the appeal of this work.
