Youko, the formidable Japanese dominatrix, sits astride her masochistic student, Inoue. She wears a lacy bodysuit, her thong-cut bottoms revealing her toned buttocks. Youko's heels dig into Inoue's shoulders as she smothers his face, her pussy and ass rubbing against his mouth. Inoue's tongue dutifully explores Youko's folds, her lubrication coating his eager lips. Youko's moans fill the room, her discipline momentarily forgotten in the heat of her pleasure, as she face-sits her student into submission.
