In the dimly lit classroom, Yuria Mano, the epitome of Japanese schoolgirl innocence, is about to receive an education far beyond her textbooks. Her teacher, Yuichi Nakajima, a man of restraint, finds himself unraveling under her doe-eyed gaze. As she innocently asks questions about the lesson, he can't help but notice her wandering hands, her subtle shifts in her seat. With a swift motion, he locks the classroom door, and Yuria, understanding his unspoken command, eagerly unzips his pants. Nakajima's massive, uncut cock springs free, and Yuria, a true student of pleasure, takes it deep into her mouth, her small hands working his shaft as she struggles to take him all in.
