After their son fails his university entrance exam, the father is devastated. Upon investigating the cause, he discovers that a popular female teacher had falsified her academic credentials. Even more shocking, it turns out she had been teaching the boy sexual knowledge during class, revealing her lewd nature. To appease the angry parents, she is forced into sexual servitude. She uses her large breasts to envelop the man's cock and performs blowjob after blowjob in apology, exposing her true perverted side. But this isn't enough to satisfy the parents' rage—soon, students and the cram school director join in, creampie-fucking her pussy one after another. Her depraved behavior escalates further into an orgy of gangbang and creampie-filled special lessons.
