Yura Kana's performance of wild deep throating is the polar opposite of the disciplined world of entrance exams. Her strict image is such that when a cock is forced down her throat, shedding tears as she serves, a scene that stirs the viewer's desire to conquer. The dull sound of her throat being slapped and her ragged breathing. Her intellectual mask falls away, and she is transformed into a woman writhing between pleasure and pain. Cruel and lascivious oral training is carried out under the guise of education. The roar that resonates in the back of her throat plays a melody of immorality.
