The teacher is asked by absent parents to check on their daughter's condition and visits the home with a camera for reporting purposes. Frequently absent from school, Yui is tempted by the teacher under the pretext of her poor grades. When told "suck it," she greedily takes the teacher's cock into her mouth; when told "fuck me," she immediately mounts him in cowgirl position, completely submissive. During the second visit, she is pushed to the limits of pleasure through toy torture. Now transformed into a woman who actively craves pleasure, Yui eventually accepts creampie after creampie. This film depicts her complete descent into becoming the teacher's obedient sex doll.
