A male employee is working overtime alone. The daily grueling work makes him doze off at his desk in the office. Unaware that the male employee is asleep, a young and cute cleaning lady, Rinka Natsume, is diligently cleaning. The man wakes up to the sound of cleaning and becomes aroused when he sees Rinka working hard. He grabs her breasts and kisses her passionately to silence her. Rinka is surprised but doesn't resist much and gives in to the male employee's demands. A few days later, when Rinka comes to clean late at night, the man is waiting for her again. This time he seems to have brought an adult toy, and when he presses a vibrator against her clitoris, her panties become soaking wet!
