The entire Masako family attended a prestigious private school, and so it was only natural that their daughter, Rina, would choose that school as her first choice. Rina shoulders the hopes of her parents. However, during a three-way meeting, Rina's teacher tells her that with her current grades, she "cannot get in." Upon learning this, Rina's mother laments and laments, saying, "I can't face my relatives," and only cares about appearances. "Can't you do something about this?" the mother pleads with the teacher. And then, of all things, the mother sells her daughter, 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 teacher gives her a deep throat instruction that makes her vomit, her throat gets pounded, and her tight pussy gets screwed. Rina should have hated the painful deep throat, but contrary to her feelings, her 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-training done to her throat. The head of the school and his secretary use toys on her throat and give her a strong deep throat 3P. What does this have to do with Rina's chances of passing the school entrance exam?
