Two students who are struggling academically are constantly reminded by their homeroom teacher and have had their parents called in, so their close friend suggested they visit her home for her older sister to tutor them. However, when they were tutored by their friend's older sister, the two boys were not focused on their studies but rather distracted by something else. With her fair skin, shapely figure, firm breasts, and beautiful face, the female 'tutor' made it impossible for the two boys to concentrate on their studies. Instead of going to their friend's house for tutoring after school each day, the young men ended up getting 'tutored' in other matters rather than their studies.
