Kaho has such a high sex drive that she masturbates in the office restroom whenever stress builds up. Her latest source of frustration is an incompetent subordinate who cannot even book separate hotel rooms for a business trip. Yet he has one exceptional talent: he is extraordinarily good at nipple play and sex. Trapped in a shared room, Kaho is driven into orgasm after orgasm until morning and gradually surrenders to his technique, ultimately letting him creampie her repeatedly.
