you're home from college with the flu and your stepmom comes in this morning to check on you. after a moment of talking, she feels something under the covers. she pulls them back to reveal the diaper you're wearing... the soaking wet very FULL diaper you're wearing! she learns you've snuck into the nursery in the middle of the night to put one on.
don't worry - this will be our secret. in fact, now that she knows, she's gonna change you out of the very full wet one you're wearing now.
she takes you to the nursery and lays you down. she undoes the used diaper and immediately you go peepee on her!! (simulated with a squeeze bottle). she laughs as she goes to clean herself off. once she does, she gets back to it - taking off the wet full diaper and showing it to you! she then puts a clean fresh dry one on you before leading you back to bed and tucking you back in.
now that step mommy knows, she says she'll do this for you any time.
