Naive student, Aki, finds himself in over his head when his curvaceous, mature teacher, Yumi, lures him into her private tutoring session. The air thick with tension, Yumi begins her lesson, her low-cut blouse revealing ample cleavage. Aki's gaze wanders, and Yumi catches him, a sly smile playing on her lips. She leans in, whispering, "You like what you see, don't you?" Aki's face flushes, but Yumi persists, guiding his hand to her breast. He hesitates, then squeezes, feeling her nipple harden. Yumi moans, her hand reaching for his cock, tracing its outline through his pants. "Let's see how well you've learned," she purrs, unzipping him.
