I have deep respect and affection for the bright and kind teacher who is the advisor of the swimming club. However, one day, I accidentally find out the teacher's secret. After the swimming club practice is over, I witness the teacher doing something with the other members by the pool after school. "Such a serious teacher... that can't be!" I couldn't help but feel depressed and erect as I watched her become a meat urinal to satisfy the desires of the other members.
