[FGAN-144] More useful than studying for exams Erotic tutor's obscene language class

I'm close to taking the exam, so I'm busy studying every day. Meanwhile, the teacher in charge couldn't come because of a cold. I can't afford to take a single day off from my studies during this important time, so I ask for an alternative tutor. - Then came a beautiful teacher with a miniskirt sex appeal. - A teacher who emits merciless sex appeal to me who forbids masturbation for the exam. Noticing that I was conflicted between reason and desire, the teacher provoked me by shifting from Japanese language classes to sex education classes.
