Part Seven

Unfortunately, I wasn’t quick enough.

Step by step, Kate walked me all the way back to the car. The soaked underwear didn’t help my mental state, I was constantly distracted by the way the snug pull-ups somehow managed to both cling to me and slightly sag all at the same time. Each step made me cringe in awkwardness, and made it that much more difficult to find the words to change Kate’s mind about this excessive prank. 

Rather than thinking of anything to say, however, the only resistance I could muster was yanking my hand out of hers as we approached the car. But it was too late. “We’re ready!” Kate exclaimed as she pulled open the car door. “Sorry that took so long. Annie had a little accident that held us up.”

I could immediately feel the heat rushing to my face at her offhand comment. Like usual, she was blaming me. The ‘innocent younger sister’ act worked all the time, but this was different. There was an embarrassing double meaning in her words. Our parents would obviously hear it as something else, but Kate and I knew exactly what she really meant.

“It’s fine,” our mother said, “Just get in. We’re behind schedule.”

With those words, my fate was sealed. 

Amidst her haste to get back on the road, our mother didn’t seem too concerned with whatever ‘accident’ Kate was talking about. Aside from my little blush, I probably looked normal. That was the point about this little dare, as no one was supposed to know what I changed into underneath. But it also didn’t offer me many options for delaying our departure from the rest stop. Not only would cleaning sticky Gatorade off my private areas take forever, but now Kate had the option to follow through on her threat and rat me out if I tried anything.

Knowing Kate, she could probably make them believe her. Not only was she a clever little actress, but wearing soaked pull-ups would easily confirm her story. “Go on, Annie,” Kate said. She gave me a serious look while gesturing to the open car door.

Annie. As if my current underwear situation wasn’t bad enough, I’d have to suffer through that nickname until I could steal away to a bathroom at our cousins’ house and change back to my regular underwear. 

Without a word, I shot her a glare and got into the car. 

Thankfully, my skirt was long enough that I wasn’t nervous about my movements giving away what I was already sacrificing so much to keep secret. However, the faint crinkling and personal knowledge of what I was wearing was still enough to keep me on edge as I climbed into the back seat of the minivan. It was my preferred spot for road trips, as I usually got some solitude thanks to the distance. I don’t mind socializing with my family, but road trips admittedly make me impatient and a little moody. I’d rather kill time with my phone.

I definitely wasn’t ready for what it was going to be like to sit in the double pull-ups. It was like landing on a cold sponge; all the drink that had sagged down during my walk earlier had slowly soaked into the thick padding. I sharply inhaled from the feeling, trying my best to settle on the wet pillow that was now my underwear. My thighs still couldn’t close completely thanks to the bulk between my legs, so I made sure to adjust my skirt to avoid even the slightest risk of one of our parents looking back and glimpsing the girly pull-ups.

Surprise, surprise, Kate had more in store for me. Rather than sitting in one of the more spacious middle seats like she did for the first leg of the trip, she climbed into the back with me. “I thought you might want some company,” she said. Her words were for our parents, but her little smirk was just for me.

“Thanks,” I muttered. I immediately glanced away to avoid staring right at her cleavage as she kept her body slightly bent as she made her way between the middle seats. It really wasn’t fair. Same red hair, same skin tone, but literally all the height and curves in the family. 

“By the way, you look so cute today!” Before finding her seat, Kate reached out and pinched one of my cheeks. Lowering her voice so our parents couldn’t hear, she added, “Your blush matches your pull-ups.” The last word was extra hushed. At least she was following through on her end of the deal.

Still, I couldn’t help but worry about the chance of her being overheard. “Kate, sit down.” I quickly swatted her hand off my face, still averting my gaze as much as possible while her boobs were more or less right in my face. It was less about jealousy, and way more about the fact that she was my sister. The last thing I wanted to see up close was her cleavage in a tight tank top. Just to hurry her up, I echoed what our mother said, loudly enough for the parents to hear. “We’re behind schedule.”

Kate just rolled her eyes. “So serious, little sis. You really need to loosen up.” Pinching down a little harder on my cheek, she finally let go and plopped down across from me in the back. “We’re ready!” she said.

I avoided the temptation to rub my cheek, not wanting to give her the satisfaction. 

Just like that, we were pulling out of the rest stop and back onto the highway. The blue-roofed building left my view in a matter of seconds, as did any possible chance of calling this whole thing off. I was going to be stuck in wet pull-ups for hours. 

Turning to me with her lips pursed in a triumphant smile, no doubt thinking the same thing, Kate got right to business. She wouldn’t have joined me in the back for no reason, after all. 

“Hey, Annie,” she said, “Can I give you a make-over?”
