The sadistic office lady uses a masochistic employee to measure the strength of the whip with a nine-strap whip, a riding whip, and a single whip. The office lady doesn't care that the man is suffering, and enjoys whipping him, switching between different whips one after the other. The office lady starts a whipping game using dice and playing cards. If the dice show a 1 or 2, she uses a single whip, if it's a 3 or 4, she uses a riding whip, and if it's a 5 or 6, she uses a nine-strap whip. Next, the man draws a playing card, and it's a tense game in which he is whipped that many times. The office lady rolls the dice with a smile, and the man chooses a playing card with a fear. The office lady then plays with the man, whipping him mercilessly with a smile. The man was unlucky that day, and he drew numbers on the cards many times, becoming her prey and pleasing her.
