It is a condition of being limited to teacher's who attend school in spring vacation, the countermeasure which the school side prepares "intensive supplementary class" using this spring vacation!!

So, i am this March "Failure" for me a crisis. However, this condition is unexpectedly nice...

What a coincidence this spring vacation teacher's who where in the school, all are attractive and cute older sister teacher's only... So, a supplementary lesson is man-to-man and naturally on holiday... Moreover, only two people in the classroom...

Moreover, true older sister of me who has gone for one's post to this school as a teacher in spring joins too, a lewd exciting private lesson starts...
