Usui, the president of the P●A club at GQE Academy, discovers that the son of a student council member is in possession of obscene books. He holds his homeroom teacher Kimajima responsible, but Kimajima has already fallen into the hands of the student council members, the real target! Instead of getting rid of them, Usui lets them play with her voluptuous body hidden under her flashy clothes to their heart's content. Together with Kimajima, who has become practically their masturbation toy, the two are forced to repeatedly serve their cum-in-the-mouth dicks as their sex toys... This is a luxurious collaboration between Usui Ren, who trembles as she orgasms with her explosive body that is unlike anything you'd see in a Japanese girl, and Mio Kimijima, who boasts perfect proportions and beauty!
