It was the perfect ending to a perfect weekend.
Annie having an accident purely because she was overwhelmed by emotions was rather telling in terms of her reverse potty training taking hold. I wasn’t sure if that was actually a thing or not, though I had to imagine constantly using her diapers was both physically and psychologically taking its toll. As long as Luna and Lilah kept on her, she would hopefully start having accidents like this more often, rather than simply relieving herself out of desperation.
I still couldn’t believe this had all worked out so well. Daring her to wear pull-ups had been so impulsive, and I had honestly expected her to refuse. But she’s always been so stuck up, and was apparently obsessed enough about being called Annelise that she was willing to embarrass herself a little for the sake of her full name. All I had to do was twist the deal in my favor, and it didn’t hurt that I managed to fake her first ‘accident’ within minutes of her putting on the padded underwear.
Everything else was just a matter of pressing my advantage and improvising along the way. I never really had a plan. Every step in little Annie’s regression was just another idea that came to me, and it didn’t hurt that the twins were on board as soon as I told them the truth. As for Aunt Miranda, she seemed to share my perspective about how Annelise had always been a pain in the ass. She probably had a more polite way of saying it, but still.
As it turned out, it didn’t take much to make a stuck up bitch come across as a whiny brat. Especially when that brat had been falsely advertising so much about her size and other features. Unlike me, she had never really grown up. Physically or otherwise.
Instead of changing Annie’s once again used diapers, I just made her sit in the wet padding as I got ready for the drive. There really wasn’t that much packing to do, as I had taken care of most of it the night before. My suitcase was a lot more full this time around, as I was taking home basically all of my sister’s stuff. She didn’t need her bras, because she didn’t actually have boobs. She obviously wasn’t going to be wearing panties any time soon. And the new wardrobe we had given her courtesy of our cousins’ old clothes was much more appropriate for her than any of the outfits she had packed for the visit.
Annie was too young for a cell phone, as our parents had made her wait until she was fourteen before finally caving and getting her one. Thankfully, I didn’t have to wait that long. Between the idea of conveniently being able to reach me while I was out, most of my friends already having phones, and a bit of eyelash batting, I got mine for my thirteenth birthday. Of course, most tweens had phones these days compared to when my sister and I were in middle school, but whatever. It wasn’t as if Annie would ever be going anywhere without supervision.
After putting my backpack on and grabbing my suitcase, I used my free hand to hold Annie’s for the last time for a little while. When she came home from her extended stay with our cousins and her time at the day camp we signed her up for, I’m sure I’d be able to treat her like a little girl just like I had been doing all weekend. As for her wet diapers, I’d let her figure out how long she wanted to stay in those. Either she’d speak up right away to get changed, or sit in the used padding for an hour or two to avoid the embarrassment of having another accident so soon.
By the time we made it downstairs, our parents were saying their goodbyes and moving towards the front door to put their shoes on. I walked Annie over to our cousins and told them to take good care of her, who assured me that she was in good hands. We had already schemed plenty last night, so I didn’t need to give them any last minute instructions. Also, I had their numbers, and was sure we’d be texting plenty over the coming week. I obviously expected pictures and maybe videos, both for being entertained from afar and increasing my collection of leverage over my little sister.
Our parents’ attitude towards little Annie had already shifted to a combination of judgmental, concerned, and impatient. After hugging her goodbye, Mom told her to behave, and to do everything Aunt June said. It really was more like she was an irresponsible child than a self sufficient college girl.
I took a private moment Annie while our parents brought my things to the car. Pulling her in for an embrace, loving that her face was practically in my boobs thanks to how short she was without her heels, I murmured in her ear, “I’ll miss you, brat. Be a good little tween this week, okay?” When she gave one of those quiet nods, I insisted on a real response. “Okay, Annie? You’ll behave, right? All week?”
“Okay,” she mumbled, “I’ll behave, like, all week.”
Perfect. Between her daytime accidents and the constant filler words, I doubted she’d be seen as anything but an immature little girl in my absence.
“Good,” I replied. Shifting back, I rounded things out by giving her a kiss on the forehead. This was a much better look for my sister. She was finally being treated the way she deserved; between her constant whining and her petite size, it made a lot more sense for her to be the younger one between us. Just for good measure, I asked while I still could, “How old are you, Annie?”
“Umm, I’m, like, twelve,” she said. No hesitation, aside from the awkward speech.
“Twelve years old,” I affirmed with a smile, nodding as I met her eyes, “Body of a tween. Maturity of a tween. And you still wear diapers 24/7. You’re twelve, Annie.” She probably was too distracted by any number of things to catch how I was subtly implying she’d be that old whether she was in diapers or not. “Be good, brat.” I stepped back and gave her a pat on the head, treating myself to one last once-over of her amusingly youthful image.
Then I gave one of her pigtails a teasing flick before swiveling on my heel and heading to the car.
As we pulled out of the driveway, I smirked at the sight of Luna and Lilah flanking my little sister on the front porch. I was counting on them having plenty of fun with her throughout her stay.
‘Later, brat,' I thought to myself.
When the house was out of sight, I took out my phone and sent a text to my BFF. Without my cousins physically around, I was going to need someone to gossip with about all of this. And it wouldn’t hurt to have a partner in crime for when Annie came back home.
At this point, I was determined to keep my sister in diapers all summer. Or, better yet, all year.
