[Modern pornographic imaginative 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 they form a pair. A teacher is 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 calm...! Even in class, the library, and at home, she is so overwhelmed that it’s ridiculous! 'If it can fit, can it be stuffed?' Every day, a unique girl is crushing the golden ball!
