[Modern pornographic imaginary genius, F4U's first collaboration!] A teacher who does not know about the ejaculation management system is concerned about Mr. Momonuma, a girl with glasses who is shaking in the classroom, and forms a pair. A teacher, confused by the sudden ejaculation management, but accepts it for the students. However, she is a super lewd tech whore even though her appearance is very sober...! Even in class, the library, and at home, she is so dragged out it’s ridiculous! “If it can fit, can it be stuffed?” Every day, a unique girl is crushing the golden ball!
