Jimmy needs more relief

About an hour later, Jimmy woke up from the pressure in his groin. He felt as though he had been holding in his urine for days, except that the feeling was more "tingly" and about six inches lower.

As he looked up, he saw that they were still driving on the on the highway. The landscape was becoming more suburban, with houses and the occasional strip mall indicating that they weren't far from the Pacific City outskirts. There were also more cars on the road, and since Francis was a slow driver, someone came whizzing past them every few seconds. The sun was on it's way down, which meant their road trip was almost at an end. The rest of Jimmy's family was quiet: his father was busy driving, while his mother and sister had also fallen asleep.

"Mom?" Jimmy leaned forward to touch her on the shoulder, but a sudden pain in his nether-regions made him pull his hand back and grab his crotch. There was an intense heat radiating through his pants, and his genitalia felt swollen.

Francis glanced at the rear-view mirror. "Hey there, Buddy. You okay?"

"Huh... Wuh?" His voice roused Audrey, who blinked a few times while wiping away the long thread of drool that was running down into her cleavage. "What is it?"

"I think he's in pain or something," Francis replied, his eyes back on the road.

"I'm... Uugh," Jimmy groaned, breathing heavily. "I feel so full, Mom... Like, like I'm going to explode--"

"Oh! Okay Honey, umm..." Alarm bells were going off in Audrey's head. I thought those **** were safe... Did we give him too much? Or too early? "We... We'll be there soon," she said out loud, giving her son a weak smile. "So just hold on, okay?"

Jimmy just nodded, cradling his inflated balls through the thin material of his track pants.

"Step on it," Audrey hissed to her husband, before undoing her seat belt and turning around, kneeling on her seat. She reached back to Jimmy, gently moving his hands away. "Honey, let me take a look at this..."

Meanwhile, Emily was waking up. "Wha--What?" She blurted out when she saw her mother bending over her seat, pawing at Jimmy's crotch.

Ignoring her daughter, Audrey fussed over the tremendous bulge in Jimmy's pants."Okay, um... We need to get you out of these, Hun. That should ease the pressure a bit. Open that button."

"What the fuck, Mom? Not in here," Emily protested. "I'm not sitting in a swimming pool of jizz the whole way there!"

Again, Audrey took no notice. As soon as Jimmy opened his fly she started tearing his pants down, revealing pale legs and a pair of black underwear. One of her son's testicles was bulging out of the left leg opening: it had tripled in size, the skin of the plumped-up ball sack growing tight and shiny as a fresh apple. "Ah--Oh boy," she gasped, before biting her tongue. That doesn't look good... We may have fucked up, here.

"Okay Honey, I don't think this can wait until we get to Salt Bay," Audrey murmured. "We'll stop and you can relieve yourself again, okay?"

"Uh... Dear, I don't think we can," Francis piped up. "We just passed an off-ramp, and I don't think there's another one anytime soon."

"Are you sure?" Audrey looked over her husband's shoulder. "What about that turn right there? The one coming up?"

"Oh, no, that'll take us all the way to Seattle," he scoffed. "Huge detour."

"But this is an emergency," Audrey began, but within seconds they were past the turn-off and back on the elevated freeway. Sighing, she turned back to Jimmy. "Okay, we'll have to do it in the car," she stammered, looking around frantically as she came up with a plan. "You... Uh... You can put a condom on and jerk off into it."

Jimmy frowned: they had bought a three-pack of condoms at the airport in an attempt to contain the worst of his ****-induced leakage. That worked for a while, but as they walked into the parking lot the friction of his pants caused a full-on orgasm. The condom went rocketing off his dick like a cum-filled missile, splattering against some poor bastard's Porsche. Condoms #2 and #3 were secured with an elastic band, but that only made the pressure worse: his forceful cumshots had busted a hole in both, less than an hour into their drive.

"I... I think we're all out," he mumbled, but Audrey was busy patting down her jacket.

"Shoot! Francis, hand me your wallet."

"What, why--"

"Your spare condom," Audrey snapped, pulling it out triumphantly.

"Oh my God, I wanna be dead," their daughter moaned, letting her head fall against the window. She had seen this kind of blatant sexual conduct on TV, but wasn't ready for her own family to be acting that way.

While Audrey fumbled with the condom wrapper, Jimmy's second testicle slowly bulged out of his briefs leg. The other leg was inflating as well, nearly ripping open as a bulge the size of a Pringles can pressed into it.

"It's not going to fit him, Audrey," Francis said, slightly annoyed. He knew that this would just fail and mess up the entire car.

But Audrey couldn't care less, handing Jimmy the little latex ring. "Honey, put this on, okay?"

Jimmy took it with one hand, pulling down his briefs with the other. A terribly-engorged shaft popped into sight, reddened with thick veins crawling over it. It reminded Audrey of a bodybuilder's arm, and though she was concerned and blushing, she couldn't help but stare. Her worries only grew as she watched Jimmy try to fit the condom over his swollen tip, the sound of stretching rubber sending shivers down her spine. It took him a few seconds of plucking and pulling before he managed to fully roll out the condom, and in the end it barely covered his glans... But Audrey sighed with relief nonetheless.

"Good, that's really good. Now just try to have, um, some nice thoughts, and... And we can get the pressure out," she said, giving Jimmy an encouraging smile.

"Oh God," Emily squeaked from the corner.

"Mom, can you put Pornhub on?" Jimmy pointed at the headrest monitor, his hand already rubbing at his latex-sheathed tip.

"Yes, sure Honey... Um, let's see..." Audrey fumbled around with the controls for a while. "...Huh, I'm getting a weird error. What's 'Father Mode?' It says I need an 'Alpha OZID,' whatever that means..."

"Puh... Please hurry," Jimmy grunted.

"Oh--Okay, I'll just--Here, I can still get to 'Dadhub.' Is that the same as Pornhub?"

"Mooom!"

"Right, right... Okay, got it! What do you want to see? Big tits are your favorite, right?"

Emily let out another squeal. "Ew, Mom! Gross!"

"Oh, don't be such a baby. We're in America now," Audrey teased, without taking her eyes off the monitor. "Or are you just jealous because you didn't inherit your mother's assets?"

"Uh... Mom, all these girls have dicks," Jimmy interrupted, knitting his brow.

"Huh, they do, don't they... Wait, what about this one? 'Son fucks bimbo Mom and cums all over Dad's...' Oh, my..."

"Good enough, just put it on," Jimmy begged. His mother obeyed, and as the video started the car filled with moans and grunts... Not to mention the slap slap slap of Jimmy's hand on his huge, sticky cock.

"Gross," Emily said again, rolling down her window in an attempt to escape the sights, sounds, and smells of her brother relieving himself.

Unfortunately, she was treated to a close-up view of the van beside them, where another young man was also getting his rocks off in the back seat... He, however, was balls-deep in his own mother's asshole.

"O-oh... Holy shit," Emily whimpered, head whipping back around just in time to see her brother jerking off faster while Audrey nodded encouragingly. She ended up keeping her head down and sending a text to her friends back home, roaming charges be damned. Jane isn't going to believe this, she thought, trying to block out the loud moans (both live and recorded) coming at her from all sides.
