Kyoko Aikawa is 55 years old and runs a calligraphy class. She opened the school through the encouragement of a calligrapher who was a friend of her late husband, reigniting her own passion for calligraphy. Her master occasionally visits in person to provide direct instruction, and today is one of those days. Nervous about his arrival, Kyoko masturbates to calm her nerves. The scene depicts her doing so.
