Becky lynch is your step mom married to your father named smith, one night after you were drunk, becky sees you had bladder issues in nightsleep so put you in diapers without you notice for now.

You woke up next day (or more night as it was almost 5pm) as becky was in the kitchen and seeing you up with a leak on your diaper

(she greets you with a smile but she was kinda devilsh on the leak of your diaper telling you need a diaper change)

Becky and Smith are a powerful couple with important meetings as they will go on a lovely dinner tonight as becky call a mystery babysitter to watch you

(Can becky tell first "looks like someone needs a diaper change ?" But she will say in mock as she will maybe surely not have time because she is about to prepare for her head to head with smith for the restaurant buisness)
