The entire Masako family attended a prestigious private school, and so it was only natural that Rina, the daughter, had her first choice of school. Rina shoulders the hopes of her parents. However, during a three-way meeting, Rina's teacher tells her that with her Rina grades, she "cannot get in." Rina's mother, who knows the truth, is saddened and concerned only about appearances, saying, "I can't face my relatives." "Can't you do something about this?" the mother pleads with the teacher. And then, of all things, the mother sells her Rina Rina to the devil. "If you let me pass, you can do whatever you want with my daughter," she says, negotiating a backdoor admission. Her homeroom teacher gives her a deep throat training that makes her vomit, gives her a throat-throbbing instruction, and fucks her tight pussy. Rina should have hated the deep throat, but contrary to her feelings of dislike, Rina throat is throbbing and she squirts with self-deep throating! Before her interview with the head of the school she wants to attend, she goes for a drool-drooling walk with a mask on and has some pre-throat training. At the end, the head of the school and his secretary use toys on her throat and give her a strong deep throat 3P. What will become of Rina?
