Chapter 42
The Road Trip, Part 42

Part 42

There was nothing to be done about it. 

The pacifier prevented me from speaking, and my legs were already spread for Kate as she continued the diapering process that was taking so much longer than I had anticipated. I winced as I felt the first puff of powder on my pelvis. It’s not that it even felt bad or anything, but the knowledge of what she was doing made me feel beyond embarrassed. I recognized the smell right away, but never in my wildest nightmares did I think that I’d personally ‘need’ baby powder. 

Kate’s expression was smug as she continued, but she didn’t have anything new to say. She just kept shaking the light blue bottle. The better way was to put a little into your hand and apply the stuff manually, but I wasn’t about to correct her on that. Her hands had been around my private areas enough. This way ended up creating a bit more of a mess, as I could feel my ass and thighs getting plenty of the powder, too. 

After another few seconds, I whined into the pacifier and shook my head again. Was she trying to use the whole bottle?! At this point, I was nervous that our cousins might smell the talcum through the diapers. Kate just rolled her eyes, like I was the one being difficult as always. “Hush, Annie,” she said, “And remember to smile. Also, you still have a lot of ‘likes’ to get through before dinner. You do want to be a good little sister in front of the twins, right?”

As if being diapered by my own sister and continuing to wear diapers wasn’t enough. And yet, I pushed a fake smile on through the pacifier and nodded my head in agreement. 

Kate smiled in response, though hers seemed more genuine. Definitely easier to enjoy all this from her end; the younger sister, in a position like this. Even after getting through all of this, and back to my regular underwear and status as her older sister, I doubted I’d ever be able to live the weekend down. I could already imagine her lording this over me forever, which is why I just needed to power through and not give her any more excuses to make it worse. 

Somehow, I needed to act like none of this bothered me; in that sense, a fake smile was actually advantageous. Though one way or another, I doubt she’d believe an act of indifference at this point. It was pretty clear all of this made me embarrassed and uncomfortable, despite how I technically agreed and went along with it every step of the way. 

“Almost done, little sis. Hang tight.” For what I hoped was the last time, Kate went back to her little station at the sink and grabbed more diapers and a couple other things. As usual, her body blocked most of my vision. “Okay, Annie. Ass up,” she instructed. The diaper pins in her hand made it easier to see that the diapers she brought back were different from the disposable ones she had been using during the changing process. She must have noticed the recognition in my eyes, since she happily offered up an explanation. “Cloth diapers are more cost effective in the long run,” she said, “Especially for a girl who has so many accidents in the middle of the day.”

My eyes narrowed for a split second before I remembered the plan I had quite literally just come up with. Softening my expression, I tried to look more neutral than anything else. Whatever. Diapers were diapers, though I was a little annoyed that she had bought both kinds just so she could clean me on one before wrapping me in the other. Did she actually expect me to reimburse her for both? Although if I was being honest with myself, I was way too vulnerable at the moment. She’d walk all over me if I tried to push back on something like that. 

For the time being, there was nothing to say one way or another. The recently purchased pacifier was in my mouth, which meant I had to awkwardly suck at it while Kate worked. That was for the better, in a sense. She was the only one that could talk, and a one-sided conversation would move things along. In a way, I was to blame for things dragging out when I first got on the changing table, since I had engaged in whatever things she had brought up. Those words were already blurring in my memory, as the latest things my sister had subjected me to had the majority of my attention. 

I simply lay still and waited for her to get started. Lifting my rear off the seat, I held myself up and waited for Kate to finish things up. We really had taken a while. If our cousins had decided to come looking for us, and happened to see Kate and I coming out of the bathroom together . . . There were plenty of non-diaper excuses for why I might need help from a fellow girl in private, but none of those would work if they glimpsed any of the things Kate had purchased. 

“Relax, sis,” Kate said, “Plenty of twelve year olds still need diapers. It’s not a big deal, okay?” She must have mistaken my nervous expression about the twins for the fact that she was about to diaper me. Though I didn’t like the idea of that, either. Why hadn’t I just hopped off the plastic table once I was clean? Oh, right. Kate had a million pictures of me, plus I had made a number of promises to her. I was a girl of my word. “You are twelve, right?” she asked.

This again. Faking another smile through the pacifier, I nodded without hesitation. ‘Happy?’

“That’s right,” she grinned. Laying out one diaper, then another, she said, “Twelve years old, for as long as you need your diapers.” A week. Of being Annie, and of being ‘twelve.’ We had gone over this several times, although it was honestly more daunting than it was tedious to hear it again. Where did Kate draw the line? Surely she didn’t expect more of the bubbly attitude I was faking for her and our cousins. There’s no way I could keep that up for multiple days. If anything, I was still holding onto the hope that she would let up about all this and let me off the hook once the weekend was over. “And your name is Annie,” she added on. 

The third diaper caused a bit of alarm as she placed it on top of the other two. All I did, however, was nod in regards to the nickname. In my mind, it also served as nonverbally affirmation about how she was going about with all this, although that hardly mattered. Kate was the kind of girl who always got what she wanted, and I wasn’t exactly in a position to push back on anything at the moment. I just wanted this to all be done, and would actually have preferred to be diapered just so I wouldn’t have to be bottomless any more. 

Taking all three layers at once, my sister adjusted the stack for a moment before covering my powdered crotch with the padding. Finally. “Head back, Annie,” Kate said, “It’s rude to stare.”

Whatever. It’s not like watching her work was going to change the outcome, and the position wasn’t particularly comfortable for my neck anyway. Still sucking on the pacifier, doing so a bit more naturally due to my nerves and not having anything else to do, I set my head down on the changing table and awkwardly stared at the ceiling. 

Other than the fact that I was officially being diapered at my age, this was actually the easiest part. Or at least, the quickest. Kate wrapped one side around me and began tightly pinning everything into place. Without any taunting or teasing, she did the same with the other side. The diapers felt a little bit too snug around me, but I wasn’t about to complain about that. Even if I had my voice, I could already picture her response. Something about how they’re supposed to be tight, in case of accidents.

“Almost done, little sis,” Kate said. I assumed the last pin was in place, because I heard her place something down. Still looking up, knowing this would all go a lot more smoothly if I continued to cooperate, I held still as she fiddled a little more with the pins. “All done!” she finally exclaimed. Dusting off her hands for dramatic effect, she took a moment to put everything back in one of her shopping bags before stepping over to my upper half. “You really are a good little sister,” she giggled. Leaning over and giving a patronizing peck to my forehead, Kate then took my hand. “Come on, little Annie. Let’s take a look at you!”

She helped me off the changing table, and I was plenty grateful it had held my weight the whole time. I’m sure it wasn’t designed for girls my size, even if I was pretty small compared to others my age. Rather than letting me put the shortalls on right away, Kate walked me over to the mirror and used a similar trick from back in the guest room. “Do you really think anyone’s going to believe you’re in college?”

There was a reason I went out of my way to hide all my immature features, and Kate really had stripped me of each and every one. My freckles were on display, my hair was up in pigtails, my chest was almost completely flat without the help of one of my bras, and I was SO short next to my sister without the usual lifts/heels I wore. And now I was bottomless, save for triple-thick diapers that made my thighs look noticeably slim. While most girls would probably desire to be that skinny, it only made me feel more self conscious about myself. And, of course, the pacifier didn’t help anything.

“I asked you a question, Annie,” Kate said. Apparently she wasn’t being rhetorical. “Do you look anything like a college girl?”

Obviously, I knew how small I was. I saw myself every morning in the mirror after a shower. But this was another level with the bulky underwear and the styling I would normally never choose for myself. Blushing, and once again a bit in disbelief as the tween in the mirror stared back at me, I shook my head. No. At the moment, I definitely didn’t look my real age. 

She just smirked. “Exactly. Now I’ve been, like, the best sister ever. Would any of your friends change your dirty diapers? Would our cousins?” That was an uncomfortable thought. Not even the changing part; I would die if any of my university classmates caught me wearing the bulky underwear I was currently sporting. The twins would be bad, too. Family gossip and all. 

Kate let go of my hand and pulled the pacifier out of my mouth with the other. “Do you have anything to say, Annie?”
