Elizabeth James is waiting for her good friend Alex Reynolds to be done getting ready so they can head out to a night of partying with their friends at a national spanking party. However, Alex decides that since Elizabeth has been acting like a immature little girl throughout the entire day, her outfit should reflect her behavior. Also, to be on the safe side because she will be drinking, Elizabeth is told to trade her panties in for super thick Rearz training pants. Initially, Elizabeth throws a fit but her tune soon changes when Alex lays her across her lap for a hard, hand spanking. Reluctantly, Elizabeth brings over her backpack and lets Alex pick out a suitable outfit: a plaid shirt, overall shorts and pink training pants. Alex warns if she keeps whining, Elizabeth will be dressed in a diaper and pacifier instead. Elizabeth complains that no one will want to play with her and she'll look so silly, but Alex explains to her that all of their friends already know that she's the baby, now she just looks more the part. Later that night, Elizabeth returns to their room to go to the bathroom, but is unable to undo her overalls in time, resulting in a very wet accident on the couch. Before Elizabeth is able to hide what happened, Alex walks in and demands to know what's going on. This proves to Alex that she should have put Elizabeth in a diaper to begin with, and makes the girl take off her wet training pants. Once again, Elizabeth finds herself across Alex's lap, this time for an even harder spanking with a mean wooden spoon and is much more submissive after being so embarrassed. With only minimal whimpering and whining, Elizabeth lays down with her pacifier and stuffed bunny while Alex changes her into a AB Carousel diaper for bedtime, along with her princess Disney pajamas. By the end of the night, Elizabeth is so in little space she's too busy playing with her stuffed bunny to even be trusted enough to pull her own pants up. Led by the hand, Elizabeth is put to bed for the night, while Alex goes back out to hang out with their friends like a big girl.
