Sayu-chan is a high school student with a full-figured F-cup. Usually, she's a serious and quiet top student, but this time she goes on an overnight trip with her crush teacher. As soon as they arrive, remote-controlled vibrator in the ryokan! Sex in the hot spring! Blowjob on the ping-pong table! Attack while sleeping! She is tormented one after another. Initially shy, her expression of pleasure and orgasm as she gains more experience is a must-see!
