The girls are arguing very loudly and manage to disturb their step-dad, who is trying to work in the study next door. He asks them to be quiet but the noise starts again almost as soon as he's left the room. This time he makes sure they know he's serious by draping each step-daughter across his knee, in turn, for a quickfire spanking each. But after comparing the results of Step-Daddy's handiwork the squabbling sisters start to argue about who's fault it was they were now both sporting bright red bottoms!
