This time, a new request has been received to the famous Sugo tutor Shichikai who is sure to pass the exam. His client's son was a virgin in two ro (a traditional Japanese court noble). A bad student who is not willing to study and always comforts himself every day. Having anxious about how to motivate, Hishiro develops erotic classes that stimulate children's boys by making full use of his disgusting body and draws out his sleepy academic abilities.
