The class teacher, ``Mr. Kana,'' was probably worried about his student, so he often visited our home. She is a talented female homeroom teacher who gently knocks on the door and patiently talks to her students who are shutting themselves in their shells. "I'm always sorry, teacher..." Even though the male guardian was hesitant, his eyes were drawn to Kana-sensei's tight ass...!
