Monica and her Step-daddy have gone to visit the newly opened ABDL diaper factory. Her outfit of choice is a crop top, jean skirt and DDLG panties.  She starts to tease him while they find a moment to themselves, knowing how much he loves her short skirts, and her girly panties. Being the mischievous girl that she is though, she teases the idea of stealing one of the unreleased diapers to try on and play with. As if by magic, something suddenly changes beneath Monica's skirt.  Her panties suddenly feel puffier becoming the all-to-familiar feeling of a diaper.  How did that happen??  Confused, she lifts her skirt and inspects herself.  It was one of those brand new, unreleased diapers she was just talking about!  Her skirt can barely cover it as she hadn't actually planned on wearing one underneath it today, resulting in her struggle to conceal it, looking around for anyone Who might be looking. Thankfully still alone. Something else was happening though.  She suddenly feels a growing urge to pee, and that feeling only continues to rise and rise, her bladder feeling as though it were on fast forward!  With barely enough time to prepare herself, she begins to wet her diaper. But the feeling of relief isn't subsiding!  Her diaper swells... She's finally stopped but her diaper is huge!  Her skirt fails to cover it even from the front, and she can't even close her legs together!  She feels around it, hoping that it doesn't explode. Apparently Step-Daddy loves it. Monica can't help teasing you again. But where can she change?  They'd better go look before anyone sees them. ***This was a custom video.
