Picky is supposed to be going to a friend's house to study, but Step-Daddy catches her dolling herself up for a night out. When he finds that she is wearing skimpy panties instead of her training panties, he hoists her over his knee for a spanking. Once her bottom is sufficiently reddened, he puts her into training panties for her study date.

Once in her friend's van, however, Picky removes the training panties and goes to the club. Unfortunately, she forgot to grab her training panties when she was dropped off that night and had to improvise. She pulls on another pair of training panties and rushes to bed. Step-Daddy heard her come home, though, so he comes up to check on her and finds her in a different pair of panties.

After getting her to confess to her deception, she is taken to the changing table for a proper diaper. She can't be trusted in training panties for a while, so it will be 24/7 diapers for a while.
