Sayu is a voluptuous high school girl with F-cup breasts. Normally a serious and quiet honor student, Sayu goes on a two-day trip with her favorite teacher. As soon as she arrives, she is attacked one after another with a remote vibrator at the inn! Sex in the hot spring! Blowjob at the table tennis court! Attacked while she is asleep! At first, she is quiet, but as she gains more and more experience, her appearance of feeling more and more and climaxing is a must-see!
