On the side of the interstate highway, a minivan pulled into a rest area. After the doors flung open, two girls and a boy climbed out of the back, while their parents exited from the front seats.

"Where's Jake?"

"He's still in there, asleep."

"Oh. Well do you mind watching him while I run the girls to the bathroom?"

"Yeah, sure."

In the back row of family minivan, a preteen fox had his legs pressed together with his hands on his lap. Pressure was building up inside him, and it was getting really uncomfortable.

"Uhh, can we stop somewhere?"

"Why?"

"I need to pee."

"Nick, were just at a gas station an hour ago. Why didn't you go then?"

"I didn't need to go then."

She looked all the traffic surrounding the car. "Well it might be a while. You think you can hold it?"

"Rrrgh... Yeah, I can try."

Nick's hands gripped his crotch

"Can't you guys just let me out on the side of the road."

"Nick, no, we can't. There's a state trooper right behind us."

Nick turned around and looked out the back window. Sure enough, there was a cop car right behind them.

"Well does anyone have an empty soda bottle I could use?"

Nobody spoke up.

"Argh, come on! There's gotta be something! I'm seriously about to piss myself."

"You could use one of Jake's diapers.

"What!? Like hell!"

"You got any better ideas?"

Nick grumbled to himself. "I'll just keep holding it."

Nick squeezed his legs together and grit his teeth. He wasn't sure how much longer he could last, but surely he could at least make it until they got to a bathroom. But the traffic wasn't clearing up; all of the cars were merely inching along the highway. He leaned forward and rested his head against the seat in front of him, closing his eyes and trying to concentrate. The grip on his privates was as strong as he could muster.

"Arghhh... God dammit." he muttered to himself. "Jake, get a diaper. Quick."

Jake got up on his knees and reached behind his seat. As he was doing that, Nick was desperately undoing his pants while trying not to spring a leak. After unbuttoning and unzipping, he raised his butt up off the seat and pushed his pants and boxers down around his knees.

"Hurry up Jake!"

His brother had a diaper in his hands and was starting to unfold it. But Nick got impatient and snatched it away from him, pressing it into his crotch and trying to adjust it afterwards. His legs began trembling, "Aah! Oh god!" It was coming, and there was nothing he could do to stop it. His whole body tensed up, and all he could feel was his hands and his crotch getting warmer as the diaper started swelling. "Aah! Aah!" He was still struggling against it, but that panic soon turned to relief. "Ahhhhhhh~~~" His muscles loosened up and he finally relaxed back down in his seat, letting the fluids flow as they've been aching to do for a while now. With closed eyes and a big smile on his face, he took a few breaths to recover and regain his composure. But as he relaxed, he heard some snickering. Opening his eyes again, he looked up and saw both of his sisters looking over the back of their seats at him.

"Hey! Do you mind!?"

"Girls, turn around. Give your brother some privacy."

"Thank you." Nick looked back down at himself. He pulled the diaper away for a moment to check on things; his stream of piss was still going at full-blast. "I hope this thing can hold all of this..." He adjusted the diaper so he would be peeing in a dry area, then pressed it against his crotch again to avoid accidentally spraying on anything else. "So what do you want me to do with this once I'm done?"
