Kinoshita is the quiet, plain accountant at his workplace, isolated from the rest of the department and seemingly easy to target for a little stress relief. But once undressed, she reveals huge tits, a thick ass, and extreme sensitivity from going so long without sex. She gushes and climaxes again and again, making him feel like an irresistible stud. Deciding she is too good to remain merely a discreet married fuck buddy, he sets out to mold her into the perfect mistress for his tastes.
