Alex won't have her little girl behaving like this so she hauls Dorothy off the floor and over her knee. She lifts her daughter's school uniform dress and spanks her bottom firmly, first across the seat of her tight-fitting white panties, and then on her bare, round bottom. But a spanking isn't the only punishment awaiting Dorothy.
Dorothy has acted like a little baby by getting this fussy, so mommy has decided to put her back into diapers. Dorothy doesn't believe that she can: she only has a tiny diaper meant for a real baby at hand, after all. It's a very babyish thing, too, of course: printed with little baby bunnies.
But Alex is determined and after powdering Dorothy thoroughly, she tapes her little girl into the diaper that she was so sure wouldn't fit her. Dorothy is thoroughly humiliated, especially when Alex tells her that bad behavior in the future might mean she has to go back into diapers...forever.
