On the day the vice principal comes to observe Mai's class, while the students read from their textbooks, Mai is touched intimately by the vice principal—her skirt is lifted, her buttocks groped, and her groin fondled. Though embarrassed, she finds the sensations overwhelmingly pleasurable. After class, she is further aroused in the locker room and forced into a deep kiss. Eventually, stripped completely naked except for her garter stockings, she succumbs to a moment of temptation that crosses the boundaries of her pride as a teacher and her professional distance from students.
