The Road Trip, Part 31

Part Twenty

Stuck with a pacifier in my mouth and a determination to not blow my cover after I had done so much to keep this between me and my sister, I could only whimper in displeasure as Kate told our parents that we didn’t need to pull over after all. 

The conversation more or less ended there, and I could only glare at Kate for her betrayal as she settled back into her seat. “What?” she asked, “I said I would talk to them. I talked to them. Now hush, little sis.”

Every fucking time! Twisting words and manipulating things so technically she hadn’t done anything wrong. It’s how she got me into trouble when we were kids, and it’s how she kept convincing me to make this road trip worse and worse for myself. And it’s not like I could put all the blame on her. Not only should I have known better, but it’s not like she was forcing me to do any of this. It may have been in a begrudging fashion, but I did agree to go along with most of this. Kate was just too good at pushing my buttons. 

I tried to distract myself with my phone, but the clock at the top of the screen was impossible to ignore. As was the pressure in my bladder, the inevitable flood that I needed to hold back until we made it to our cousins’ house. Thirty-five more minutes, plus the effort of getting to the bathroom while no longer being able to clamp my legs together. 

Each minute was more painful than the last. A small pothole was enough to cause me to briefly lose control again, and another short stream of pee added to the warm, damp spot I was already sitting on. I squeaked into the pacifier and looked at Kate with wide eyes, but she seemed completely disinterested in my plight. She was focused on her own phone, texting away without a care in the world while I was fighting to keep the most humiliating thing possible from happening to myself. It hurt to try, but that was better than the alternative.

Today wasn’t my lucky day, however, as the stretch of highway that we were driving on was the kind that was in need of some repair. Less than a minute later, we hit a slightly larger pothole, and that was it for me. 

More warm pee was released into my pull-ups, completely out of my control. ‘No! Please, no!’ I pleaded to myself, to my body. But it was too late. I couldn’t do anything to prevent the dam from bursting. A wave of warmness spread all over my crotch, and then the U-shaped padding underneath took effect. The section underneath my ass began soaking things up, immediately followed by the front of the pull-up. Unlike the cold Gatorade, which had been dumped in from the back, this was warmth that was spreading outward. From me. Because I was wetting myself. 

I tried to hold it back, I really did, but my efforts were fruitless. If anything, the muscles in my bladder were doing the opposite of what I wanted; pushing, to release everything. It’s like my body was punishing me for resisting its natural urges. I clutched my phone in my hands, pretending like nothing was wrong, but I could feel my cheeks radiating heat as I blushed from the faint hissing that the pull-ups only slightly muffled. As my stream continued, the warmth in the pull-ups spread, soaking the padding underneath my ass and making its way past my crotch and towards my waist. 

Were the pull-ups enough to keep any of this from leaking?! At first, I had been horrified that this was happening to me. But now, I was nervous for a whole new reason. Between the full bottle dumped down my underwear earlier, and the ongoing flow, how much could two pull-ups take? I also hadn’t realized my bladder was this full. It took at least a full minute for the steady stream to finally fade into a trickle. I kept glancing down at the seat, desperately yet subtly trying to ensure that nothing had soaked through to my skirt or the leather beneath me. 

It was only when I looked up again, still horrified that I had just wet myself as a college girl, that I noticed Kate grinning. “You didn’t!” she exclaimed, clasping a hand over her mouth to keep from laughing out loud. “Annie, we’re almost there,” she said, lowering her voice so the conversation was just for us, “You couldn’t hold it just a little longer?”

I felt so small, so defeated. While this was Kate’s fault in a lot of ways, I couldn’t but blame myself as well. How did I let things get so out of control?! I didn’t just wet myself, I soaked the pull-ups. Sitting in a warm, wet mess that was a lot worse than sticky Gatorade, I could only meet Kate’s eyes and offer a tiny shake of my head. 

No. I couldn’t hold it. I tried to tell her, but she didn’t listen. 

“You know I used to babysit, right?” she asked, “And whenever little girls have accidents, they need to be punished. And no, I can’t go easy on you just because we’re sisters. Let’s start with your phone privileges.” Just like that, she plucked the phone from my hands before I could register her words and make a move to stop her.

“Mmm!” I whined into the pacifier, “Kate-”

“Ah, ah,” she said. Before I could mumble more than that through my teeth that had to stay together to keep the accessory in, she grabbed it and pushed it back against my lips, “No talking. Nod if you just had an accident.”

Blushing all over again, I meekly nodded my head twice. The pigtails brushed my shoulders from my movements, though the childish braid of my beautiful red locks was nothing in comparison to the ballooned pull-ups between my legs. 

“It’s a good thing we put your pull-ups on before the drive, isn’t it? Otherwise you would have ruined your cute outfit and these nice seats. Now, if you want my help getting cleaned up without our parents finding out, you’re going to have to do something for me.”

Once again, I was stuck. Before, there was at least the weak defense that I could use if Kate tried to get me in trouble with her innocent angel act. But now that I had soaked the pull-ups with my own pee, I couldn’t claim Gatorade. If anything, the sports drink was working against me worse than before, as it served to make this ‘accident’ look a lot worse than it actually was. 

Rather than silently communicating with my head, I just met Kate’s eyes and waited. It was the one bit of defiance I could find as her older sister. I wouldn’t write her a blank check, but at this point I was embarrassed and vulnerable enough that I felt like I’d probably end up going along with whatever she said.

Or so I thought. 

Cutting right to the chase, and certainly not mincing words, Kate looked me dead in the eyes and gave the pink pacifier an assertive push. Her expression was mostly serious, but there was the slightest hint of a smirk at the edge of her lips. I knew my brat of a sister well enough to know that this wouldn’t be a fun idea, but I had no idea just how far she intended to take things until she bluntly said,

“I think you should shit yourself, Annie.”
