Doskebe's mother in charge of explosive ass ejaculation, Fujiko Minegishi

There is a rumored student dormitory that if you live in any kind of vain life, you will be accepted to the school. Fujiko, who is the manager of this dormitory without any strangeness at first glance, uses secret student management methods to concentrate on his studies. The contents were radical in that they fed beautifully large buttocks, wore a stewardship between the crotch of the dormitory students, concentrated on studying and gave 'a reward' for ejaculation only to those who achieved high grades. Even today, students dream of passing and superb ejaculation, and continue to go to the desk all the time.
