Luke had to pee so badly, his bladder was about to burst. His mom and older sisters were all crammed into a small van for a road trip. Luke desperately needed to relieve himself as he was squirming uncomfortably in the back seat.
"I gotta pee so bad, it's an emergency! I can't hold it much longer!" Luke exclaimed frantically.
His mom looked back at him from the front seat with concern. "Oh honey, what are we going to do? There's no rest stops for miles. You might just have to wait it out."
Luke squirmed uncomfortably, the pressure in his bladder becoming unbearable. His older sister Stacy who was sitting next to him noticed his distress. A devious idea formed in her mind.
"Hey Luke, I think I know a way you can get some relief," Stacy said with a smirk. "Why don't you pull out your dick and let us milk it like a cow? I bet a nice long piss would do the trick and save your poor bladder."
Luke's eyes widened in surprise at the lewd suggestion. "What? You want me to whiz on you? That's so weird!"
Stacy smirked back at him. "Desperate times call for desperate measures, bro. Besides, I've heard rumors your dick is huge. I'm curious to see it in action. C'mon, whip it out! We'll make it worth your while..."
Stacy unbuttoned her shorts and shimmied out of them, revealing her lacy thong underneath. She reached over and boldly cupped Luke's crotch, feeling his cock throb and stiffen through his jeans.
"Ooh, it IS big!" she purred, now fully invested in her kinky plan. "Mom, Paula, you have to see this too! Luke's packing some serious heat down here. I bet he's a real pissmaster."
Luke's mom and other sister Paula turned to look, their eyes widening as they took in the sizable tent forming in Luke's lap. His rock hard erection was clearly outlined and straining against the confines of his fly.
"My goodness, Luke! I had no idea you were so... gifted," his mom remarked, her voice dripping with lust. "Well, in that case, why don't you take Stacy up on her offer? I'd love to get a taste of that big boy too."
"Yes, let it rip!" Paula added breathlessly. "Piss all over us! We want to feel your hot golden stream!"
Their vulgar urging was too much for Luke to resist. His cock was throbbing almost in agony now, aching for release. With a groan, he unzipped his fly and pulled out his enormous dick.
It sprang free, slapping against his belly before bobbing obscenely in front of his face. His sisters gasped at the sight of it - he was hung like a horse, thick and veiny and at least 10 inches long.
"Woah, it's huge!" Paula whistled in awe. "I can't believe we're related to that monster."
Luke's mother ran her hand along his shaft, marveling at the smooth skin and impressive girth. "Mmm, yes, this is definitely a prize-winning specimen. I'm going to enjoy savoring your tasty piss, son."
Stacy grabbed Luke's cock and pointed it towards her face. She opened her mouth wide, sticking out her tongue in anticipation. "C'mon Luke, give it to us! Let loose with that big pee pee!"
Luke couldn't hold back any longer. He gripped his immense dick and aimed it at his sister's eager mouth. Suddenly, a powerful stream of piss erupted from his cockhead in a high-pressure jet.
"AAHHH FUCK YESSS!" Luke groaned in relief as his dick let loose, spraying Stacy's face and filling her mouth with his acrid yellow piss. Stacy gulped it down greedily, not spilling a single drop.
"Hnnnggh your pee is so hot!" she moaned, savoring the taste of her brother's heated urine. "Don't stop, I want it aaaaall!"
His other sister Paula dove in, opening her mouth next to Stacy's, fighting to get a taste of Luke's endless piss flood. The two girls lapped at his cock like thirsty bitches at a trough, swallowing every drop.
Finally, Luke's mother joined in, pulling her shirt down and offering her tits. "Don't forget about me!" she demanded breathlessly. "I want you to soak my big mommy milkers!"
Grinning, Luke redirected his golden stream, soaking his mom's heaving breasts. Rivulets of piss ran down her cleavage and dripped from her hard nipples. She squeezed them, squirting out her own milk and mixing it with her son's piss.
"Ooh Luke, you're going to make me cum!" she cried, her eyes rolling back in ecstasy. "Keep peeing on mommy's tits! Drown them in your pissy flood! Ahhhnnngh!"
Stacy and Paula continued to suckle at Luke's cock, noisily slurping his piss straight from the source. They gulped and swallowed feverishly, determined to drain him dry.
After nearly a full minute, Luke's stream finally began to slow to a trickle. His sisters milked him for every last drop before letting his spent, dripping dick go with wet plops.
They sat back, panting, their faces drenched and dripping with piss. Stacy licked her lips with satisfaction. "Mmm, that hit the spot! I knew your huge cock would have some serious piss packing power. You sure showed us who's boss."
Luke smiled weakly, feeling completely drained both physically and mentally. He tucked his softening dick back into his jeans. "Geez you guys are freaky! Who knew using my dick as a piss hose would be the ticket? I'm all drained now though. Think I'm gonna pass out..."
As Luke's eyes fluttered closed, his mom leaned over and kissed his damp forehead. "That's my good boy. Just rest now. Mommy and your sisters will take care of you. You'll be ready for another round soon I'm sure..."
She glanced down at Luke's crotch with a wicked gleam in her eye, already contemplating when and how they could get him to piss on them again. After all, they had a long road trip ahead of them...
