"Thanks! I'll be sure to get it back to you before the train arrives. Any chance I could get your contact information in case we miss each other?" he asked with a nervous chuckle.
Kara have him a half-smile. "You can have my e-mail address. I check it so often there's no way I'd miss it."
Frank actually lingered for quite while chatting us up, especially Ginger and Kara. I was trying to decide whether or not they were in flirting territory when I noticed Samantha had crossed her legs. I didn't think much of it until about twenty minutes later when my eyes fell on her again. By then, she was holding herself and rocking her torso as subtly as she could, and I realized that her bladder had chosen a rather unfortunate time to start filling up. She hissed a couple of times at Ginger to signal for her to wrap it up, but she just couldn't do it loudly enough without calling attention to herself. I managed to catch her darting eyes a couple of minutes later, as her urgency was fast becoming less subtle, and jerked my head in the direction of Kara's and my cabin. She rolled her eyes and threw her hands up as if to wonder how the hell she didn't think of it. She then rose to her feet as casually as she could and hurried to the door, grabbing her crotch and inhaling through puckered lips as soon as she was behind Frank.
I led her out and slid my key into the slot without a moment's delay. Sam had already unzipped her jean shorts before I'd even quite managed to close the door and re-lock it, and just as I did so, she unbuttoned them in an instant and practically tore them together with her panties down to her shins. She had barely begun collapsing onto the nearest seat before a forceful torrent of pee just exploded out of her. The poor girl gasped as her butt finally landed on the already wet seat. "Oh, my God!" she breathed before moaning long and loudly. The flood hissed audibly against the cushion as she spread her legs and kept peeing desperately. "Oh, that feels so much better!" She continued openly relieving herself for about a minute and a half before she finally sighed in deep satisfaction as her deluge dwindled almost as quickly as it erupted. "Oh, I owe you one, Terri!" she said breathlessly. "I don't think I could've held it much longer!"
Sam dutifully cleaned up after herself, and we returned to find Frank ironically gone. When she realized what had been happening, Ginger apologized profusely for her apparent inattentiveness. Sam just assured her that the immense pleasure of relief had been worth it!
By that time, nightfall was fast approaching, and we all decided to watch a movie or two on Ginger's laptop before going to bed. Fortunately, there were no more wet interruptions. That would come later after Kara and I retired to our own cabin for bed. I was just about to execute the final cleaning for the day when Kara idly stood up in front of the seats in the nick of time. I'm not even sure she noticed her timing as she promptly lowered her boxer shorts, planted her bare butt on the nearest seat, leaned back, and let what seemed like a gallon of pee freely gush out of her, absolutely drenching the cushion. She peed for a minute and a half with her eyes closed in contentment before a satisfied sigh escaped her lips. She rose to her feet just long enough to pull her boxers back up before lowering herself to the floor and crawling into her sleeping bag. I chuckled to myself and then efficiently cleaned up her huge puddle before climbing into the fold-out bed above the seats.
All good things must come to an end, but we certainly made the most of returning to the States. Sam went commando in a skirt on the plane again, and I envied her when I saw her shamelessly empty another full bladder onto her seat. The second time, she was in the middle of snacking on some Ritz crackers that we'd packed when she pulled her skirt out of the way again with her free hand and simply spent another minute or so pissing once more into the fabric.
Fairness was restored when we reached Kara's car in the airport parking lot. Kara was driving this time, so as soon as she climbed in, she unfastened her jeans and pulled them along with her panties down to her ankles so that she would already be prepared whenever the urge hit. Sam didn't even bother putting her panties back on when we landed, so she just sat down and could have relieved herself right then and there if she needed to. I hadn't planned on it, but since I had gorged myself on the last of my awesome European fruit drink all the while we were collecting our luggage, the timing was just right, so I was lowering my own pants as soon as I was in the car and peeing forcefully onto the cushion before had we even pulled out of our parking space, moaning in pleasure at the combined feeling of the deflating pressure and warm puddle around my thighs and privates. Ginger, sitting in the backseat next to me and realizing that she was the only one with her pants still on, shrugged and rectified that in no time.
Although she was the last to drop her pants, Ginger was only the second rider to wet her seat, and quite thoroughly. She was reading some iZombie fanfiction on her iPad when she simply diverged her thighs, leaned forward a bit, and began peeing without even looking up from her story. Her seat was completely drenched by the time she finished.
Kara and Sam, however, took it to a whole new level. About halfway through the trip, we agreed to stop at McDonalds to fill our stomachs. We were waiting in line at the drive-through when a sudden loud hissing signaled that Kara had just let loose on her seat as she idly kept up with the queue. She barely finished peeing her usual gallon before it was her turn to order! Finally, we were pretty close to home and had stopped at a gas station. While Kara was pumping the gas, I suggested that we take the opportunity to clean up the seats. "Hold that thought," Sam piped up. Even before she finished the sentence, I could hear her release another torrent of pee onto her seat. She moaned softly and continued pissing for another minute or so. "Okay, let's do it!" she said when she finally finished relieving herself. "I doubt any of us will have to go again before we get home."
