A young J-cup female teacher is assigned to a "nude school" whose educational philosophy is that "students and teachers should face each other naked!" The principal himself gives her one-on-one instruction as she is confused in an unfamiliar environment. The busty teacher is touched by the spirit of compassion as she uses her mouth and beautiful big breasts to serve the penis, and when she is penetrated in the slit, she awakens to the true meaning of education and accepts this unique rule.
