In Tokyo, the teacher in charge of the D/M class at the Ejaculation Management Academy, Hinako Nanase, is busy with the guidance and management of erections and ejaculations. You're not just going to shoot out cum whenever you feel like it, are you? You've got to fill up those balls first. Then, manage ejaculation by tying up the testicles with rubber bands. Get your dick hard looking at the teacher's pussy. When you're about to come, hold back yourself. That's self-management. Under the agonizing guidance of the sadistic teacher Hinako, male students who can't help but ejaculate multiple times a day despite having their cum managed, school sex life.
