Backed by her position as a school teacher, she turns her attention to a mysterious sexual fetish, leading to developments beyond imagination. During class, she deliberately suppresses her urge to urinate, indulging in this unique pleasure, and her mannerisms and behavior begin influencing her students. However, one day, she can no longer hold back and crosses the line, standing in front of the blackboard as a massive stream of urine spills down to her feet in a shocking scene. Woven with such intense depictions, this work holds a unique and compelling allure.
