Yuria Mano, the eager Japanese student, finds herself in detention with her strict, well-endowed teacher. She's been a naughty girl, and he's decided to teach her a lesson she won't forget. With her big doe eyes and pouty lips, she begs for a chance to make up for her mistakes. The teacher agrees, but on his terms. He unzips his pants, revealing his thick, veiny cock to the blushing teen. Yuria, excited and nervous, takes it in her small hand and begins to stroke. The teacher guides her, teaching her how to use her mouth, her tongue, her throat to pleasure him. She gags and drools, but she's a fast learner, taking him deeper with each thrust. Just when she thinks she's mastered the art of deepthroating, he pulls out a vibrator, ready to teach her another lesson.
