Reiko is a teacher, but she also has a physical relationship with her student. On the surface, she behaves as a strict teacher, but after school, she enjoys the young body. She enjoys this double life, but recently, her student has started to ask for a relationship even inside the school, seeking more thrilling pleasure. She refuses because it's dangerous, but when he caresses her forcefully, she becomes weak in the knees... In the bathroom. In the staff room. In the nurse's office. Reiko repeats her secret affairs right next to her students.
