パイズリ教室-成績下位はP組に隔離され強制連続射精教育を施される学校-

When your grades drop to lowest in the class,
you are moved to Class P, which does breast-fucking everyday.
As the only boy here, the girls all want to breast fuck you.
But it changes into a harem hell when they won't stop
no matter what you say, or how many times you cum.
