Becky and Ashley start getting ready for their class with Miss Rachelle. The girls get setup, put their aprons on and start their class. But when Becky turns around, that's when Miss Rachelle notices her puffy Molicare purple butt.
Miss Rachelle demands that Becky explain to her why she's wearing a diaper. To which Becky explains how she wet her pants outside, and when she came inside Ashley forced her into a diaper. Miss Rachelle asks Becky if she would like to skip ahead in some lessons so she can get some revenge on Ashley and put her in a diaper too! Becky, of course, happily agrees.
Ashley, on the other hand, doesn't want to go back to this portion of class. She's already had to do it and doesn't think it's fair Becky gets to skip ahead like that. But, Miss Rachelle says Ashley gets diapered by Becky, therefore Ashley gets diapered.
The girls girls go back to the couch so they can lay Ashley down and get her diapered up. Once diapered, the two girls go back to their tasks. Only, not too long after Ashley realizes she really has to use the bathroom. Miss Rachelle tells her too bad, that's what her diaper is for. Plus, it'll give Becky some experience changing diapers.
Not wanting to wet herself, she tries holding it and tries begging some more, but no one will have it. Becky even goes so far to "help her along" by tickling her until Ashley wets her diaper in front of both of them. Now that her diaper is soaked, she's hoping for a diaper change.
