Once she is assigned her position within the firm, Ai Mizushima is introduced to her direct supervisor. He wastes no time instructing Ai on the daily duty he expects her to perform for him- he wants sex, every day, no questions asked- and he wants it on her desk. Because he is not much older than her, he thrusts inside her much longer than the old men on the board. If every day is going to be this busy , Ai can only think to invest in some good lube to keep in her desk.
