:: MOVIE DESCRIPTION ::
Sarah has been a real brat to her older sister, Joy. Sarah has been going through her big sisters clothes, looking for something to wear out. Joy walks in and catches her, and Sarah tries to claim she was there looking for her cat. The same cat that mysteriously just ran off!
Joy goes off on her telling her that she's not going to fall for that one. That she's been borrowing her clothes, and worse, borrowing her panties and bringing them back wet! So this time, Joy has a solution. She's going to put her little sister in a diaper, and if she can manage to bring that back dry, then she'll let her borrow clothes.
Sarah won't have any of that. So she tries to get out, but Joy is much much bigger than her little sister. Sarah was born a little small, and thus, is the smallest of all her siblings by a stretch. Joy has no problem putting Sarah into a neck hold and slamming her onto the bed. Sarah, realizing she has no hope of beating her bigger sister, still mouths off but let's Joy diaper her. And as long as no one is getting to her panties, no one would notice. Which leaves Sarah mouthing off even more to her big sister.
Later that night, Sarah comes home and to be expected, is in a totally soaked diaper. Joy teases her a bit, but Sarah claims she couldn't get it off, that is was on too tight etc. Joy, of course, knows just how easily it could have come off so that means her little sister intentionally wet her diaper. But she can't just leave her walking around wet, so she does the nice big sister deed and takes off her little sisters wet diaper.
