Seeing his son's poor grades, the father asked his friend's wife, Cai Cai, to tutor him. However, upon seeing Cai Cai's beauty and physique, the son couldn't concentrate on studying. Seeing this, Cai Cai, in order to relieve the accumulated sexual desire, used extremely vulgar "special tutoring" methods, restoring the son's mental and physical vigor.
