Kinoshita is the quiet, plain accountant at his company. She keeps to herself in the department, making her seem like a convenient choice for a little relief from his stressful job. But once her clothes come off, she reveals huge tits, a big ass, and an incredibly sensitive body—perhaps because she has not had sex in ages. She squirts and comes over and over in his hands, almost convincing him that he is some irresistible stud. Deciding she is far too good to remain just a discreet married fuck buddy, he sets out to train her into exactly the mistress he wants.
