Tay gets home and rushes into her room for a quick change. She's been hiding the fact she's wearing diapers. Lately, due to college and everything else going on in life. Once in her room, she quickly changes out of her wet diaper and puts on a nice, fresh, dry diaper. Just in time too because as soon as she gets the last tab of her molicare on her sister Becky barges in.
Tay quickly throws her blanket over herself, covering her diaper. Becky doesn't notice, but she's quite the bratty little sister. She wants some attention from her big sister. Tay tries to get rid of her little sister by telling her she needs to get ready for a test tomorrow, and that she wants to be left alone.
Becky doesn't go for it. She continues to bug Tay. She even tries to start up conversation by telling her sister that she wet herself. Tay is a little offended, but can't say anything . . . Well, until Becky just yanks the sheets off her revealing big sister in a diaper. Becky doesn't understand and starts teasing her, begging and begging to know why her sister is wearing a diaper!
To get Tay to admit why she's wearing a diaper, Becky starts tickling her sister. She keeps tickling and tickling, begging to know why she's diapered. Tay can't take it though and even though she just changed out of a wet diaper, she wets herself again. She practically floods her diaper. Tay breaks down and explains to her little sister why she's wearing a diaper. A college age girl wearing a diaper because she can't control her bladder anymore as can be seen by her now wet diaper.
Becky calms down and decides her big sister needs a change. Tay is flabbergasted, but Becky continues to hunt down her diaper supply and change her sister. As she's searching though, she comes across other items such as a onesie and cloth diapers. Since Tay said she wanted to go to bed, may as well wear her night clothes, right? And a nice, thick diaper too. Despite being the "b@by" sister, Becky does a good job of changing her big sisters diaper.
Now that Tay is changed, Becky begs to be diapered. After some bratty princess whining, Tay gives in. Tay unzips the petite Becky's footed PJ and begins diapering her. Becky though wants the pretty pink cloth diaper with the pink panty. Once both are all diapered up, Tay still wants to go to bed. She really does have an exam the next day. Of course, bratty little sister still wants to talk. This time though she has a small confession . . . She likes the diaper. She really did pee herself earlier because she wants to be back in diapers. Tay isn't really amused since she has to wear them, but is ok with it but really wants to go to bed.
The next morning they wake up. Tay is of course wet and gets up to get changed. She didn't expect to see a wet spot under her little sister though. Becky peed right through her diaper! On purpose too! Tay quickly gets up to get her sopping wet sister changed. She goes to put Becky back in panties but Becky wants another diaper. Tay caves, grabbing one of Becky's old diapers. Only Becky has grown since then. Tay grabs another Molicare and gets her little sister all changed. Now Becky wants to change her big sister to.
Now that both are freshly diapered, Tay makes Becky go throw the wet sheets into to wash. So Becky grabs the sheets and heads out. Tay freaks, telling her to go put on some clothes so mother doesn't see her in just a diaper. Becky, liking the diapers, doesn't mind getting caught so she walks right out in just her diaper.
