On The Road Again - Chapter 19

The chugged water started to hit both Isla and Jill about an hour after they emptied the bottles, but when it hit, it hit hard. Jill started to get fidgety, and Isla crossed her legs the best she could with the added bulk from her already wet diaper. They started exchanging casual glances, recognizing the desperation in each other's eyes. Isla knew their current competition: fill your diaper the most without it leaking. She had already filled it a little bit and didn’t want it to leak, so she started to hold her pee in rather than just letting go.

Jill, on the other hand, had a dry diaper, so Isla wasn’t sure why she was holding on. Through their eye contact and subtle smiles, Isla discovered that she was adding a competition to the competition. She wanted to see who could hold it the longest. Isla obliged, crossed her legs and turned her head to the window.

“How much longer till we’re there?” Jill asked Kennedy, who was softly singing along to her car tunes.

“Another hour. Why? You need to stop?” Kennedy asked with a smirk.

“Nope! Just curious,” Jill responded.

“Okay, well if you need to stop let me know; it was an eventful day for your bladder yesterday!” Kennedy continued.

“Good thing you’re driving. If you had passed out like Heather is, you might have wet the bed again. Or, the seat rather,” Jill snapped back. Heather snorted, fast asleep in the front passenger seat.

“Yeah yeah, I was drunk. Are we ever going to live that down?”

“I don’t know. Are you ever going to let me live my accidents down?”

“Why don’t we just all forget about all accidents, hey?” Isla cut into the sister's bickering. “If last year and yesterday were any indications, none of us deserve to be talking any shit about anyone's bladder control.” Jill smiled at Isla for her intrusion. After a beat of silence, Isla continued. “This is supposed to be our big fun final road trip! Let’s be civil at the minimum.”

“Yeah yeah, okay, I’ll be nice,” Kennedy rolled her eyes and sighed.

The need to pee built during the conversation, and when Isla and Jill refocused back on the state of their bladders, they both realized just how close to losing control they were.

Jill pulled out her phone and turned to Isla. “Wanna play hangman?” She asked. Isla nodded, then Jill started writing into a note on her phone. Then, she handed the phone to Isla. Isla looked at it and saw that there was a hangman game in the note but that there was also a message:

Jill:  “How much longer can you hold it?”

Isla put in her guess for the letter, then typed a response and handed it back to Jill.

Isla: “Like maybe a few more minutes, you?”

They continued to pass the phone back and forth.

Jill: “I’m already leaking.”

Isla: “Why don’t you just let go?”

Jill: “I’m trying to win… ;).”

Isla: “Win the battle, but not the war. I’m only holding so that I don’t leak.”

Jill: “Fair. I kinda like seeing you struggle over there.”

Isla: “Am I being that obvious?”

Jill: “You keep changing the way your legs are crossed and gripping your knees.”

Isla: “Well, you’re not so subtle yourself. You fidget like crazy when you’re desperate.”

Jill: “I can’t help it. It’s also making me horny….”

Isla: “Really?”

Jill: “Yeah, IDK, I think it’s kinda hot to lose control when it’s into a diaper.”

Isla: “I’d say it’s kinda hot in or out….”

Jill: “You’re so dirty.”

Isla: “I blame you.”

Jill: “True, I did kinda make this a sex thing didn’t I?”

Isla: “I think it was already on the verge of being a sex thing for me,

Jill: “Well I’m glad I’m the one to have awakened that in you.”

Isla: “Likewise…”

“What’re you two doing back there?” Kennedy asked.

“Just playing hangman….” Jill responded, and both girls blushed.

“Uh-huh. You two become BFFs overnight or something?” Kennedy continued. Isla and Jill looked at each other and chuckled.

“Pretty much!” Isla replied. Kennedy turned her eyes back to the road, and the girls turned their eyes back to the phone. Jill started typing her message but suddenly stopped. She looked up at Isla with wide eyes. Jill erased what she was writing and began frantically typing a new message.

Jill: “It’s coming out!”

Isla: “OMG! Are you trying to stop it?”

Jill: “Yeah, but like it just doesn’t stop! It feels amazing.”

Isla: “I wish I could feel you fill it again.”

Jill smirked when she read the message, but then her face turned pale, and her smile faded. She suddenly reached down and felt around her butt.

“Shit,” she whispered.

“What’s wrong?” Kennedy asked.

“Nothing! Just lost...hangman….” Jill replied, then frantically began typing.

Jill: “I leaked. Look at my butt.”

Isla looked up from the phone to see Jill turning her whole body to the window, so a clear view of Jill’s butt was on display. The first thing Isla noticed was just how much the diaper showed under Jill’s sweatpants now that it was full. Then, she noticed what Isla wanted her to see. A wet patch about the size of a baseball had formed below her right buttcheek, outlining her diaper slightly. Isla snorted with a laugh, then typed into the phone.

Isla: “I guess I win then!”

Jill: “Yeah yeah, rub it in. You still have to prove you can fill yours without leaking though….”

Isla: “Well if I leak, we’ll both do each other's punishment. Deal?”

Jill: “Deal…now pee.”

Isla looked up from the phone and made eye contact with Jill. Jill was giving Isla this smug grin, and Isla raised an eyebrow. She leaned back into her seat and, for some reason, cleared her throat. Jill laughed.

Isla knew she probably would've held on a little bit longer. Certainly not all the way to the hotel, but long enough that her diaper would at least still be warm when they got there. She figured it was an advantage since now she could, in theory, regulate the amount of pee she was letting out instead of holding until she totally lost control.

Jill watched on eagerly as Isla took a deep breath, relaxed her bladder, and prepared to push.
