Rainbow has gotten in trouble for humiliating her step-sister. She threw the poor girl out the front door with her diaper showing and constantly teases her for wearing them. So, Step-Daddy decides she needs some time in diapers as well. After putting her in a thick diaper, he locks her in the pillory until she soaks her diaper. An hour in the pillory is too much for her, though, and she wets just to get released. Of course, Step-Daddy has to tease her a bit for wetting before he releases her. A lesson must be learned.
