After failing the university entrance exam twice, the young man lost all motivation to study, so his parents called in the talented private tutor, Hitomi Ueno Ueno. Wanting to impress the beautiful and sexy Hitomi, the young man resumes his studies! Hitomi, nicknamed the "virgin killer", shows her true colors to the young man who is too simple and still a virgin. To get him to concentrate on his studies, she naturally shows him masturbation, gives him a blowjob, washes him in the bath, and jerks off his erect penis. However, she says that "if you get full marks, you can have sex..." and that this is the secret to improving his grades.
