On a quiet afternoon, two floppy eared puppy brothers are happily playing around in their living room. “Waaaaaiiiiiiit!” In the midst of an impromptu couch pillow/tickle/paw fight, the younger of the pair suddenly brings the battle to a halt. "I have to pee!" He declares with a giddy wag in his tail for the silly announcement. The older brother giggles, also finding boyish intrigue in that knowledge, but he promptly dismounts his sibling, and the pair skitter off to the bathroom.

They both arrive at their relieving destination. The younger brother pauses by the sink to bend over and pull down his shorts, baring his blue cartoon briefs clad butt. Just as he steps out of his shorts, his older brother jumps in front of him with an opportunistic chipper "I have to go too!" Being the bigger boy, he only tugs down the front of his pants to let his uncut length slip out. A healthy stream quickly spurted forth and burbled into the toilet.

"Hey!" The younger pup protests through chuckles, wrapping an arm around his big brother and peeking around his shoulder. His chuckles are contagious, the older brother sticks out his tongue as he pulls back his foreskin and they both titter at the silly sight of a golden river shooting out of his pink tip. The younger pup's footpaws stomps and he bounces out of desperation, but he doesn’t complain watching the very last drips of his big brother’s potty break. "My turn!" He pipes, releasing his brother to hop in place. 

"Wait, wait" The older brother giggles as he shakes his dripping member with exaggerated gusto, flopping his little worm far longer after the rouge pee droplets had disappeared. 

"Come oooooon!" His brother whines, his own giggles growing pained as he squeezes down on his undies bulge and does a twisting step back and forth. 

"Wait, I think I feel more!" The big brother teases, closing his eyes and grunting as he pushed on his empty bladder. 

"Hrrrrrrng!" The younger brother grapsed his older counterpart's hips and grunted as he tugged with all of his baby bro might, but he barely budged his snickering sibling. He gasped feeling pee surge to his bits and quickly released his brother to jam his paws between his thighs and double over. 

The older pup laughs at the display. "I'm almost done!" He claims, leaning his crotch forward to aim an imaginary stream. 

The younger brother lets out a pained groan and shivers, feeling pressure grow behind his tender length. But suddenly, an excited smile pops on his face. "Imma pee on you!" He leans up on shaking knees and impatient feet, fishing through his briefs and pulls out his already leaking boyhood with a tail wagging in anticipation for that sweet release. His instantly accelerating stream lashed upwards along his brother’s body like a rising whip. He arched his back and tried to aim to keep up with his eager bladder. 

His older brother first flinched, feeling his side suddenly grow hot and wet with a heavy pattering, only to screech when yellow rain doused his neck and shoulders. "Aaaaaaaa! Ok, Ok!" He threw himself against the wall to escape his little brother's wrath. 

The younger brother lets out a shaky giggle. He squeezes his tip and clenches to stop the flow, but his bladder, already teased with relief, angrily refuses and he yelps as he's hit with a sudden pang in his crotch. He takes heavy breaths and waddles forward with his member dribbling between his fingers. He huffs out as he finally reaches the toilet and completely relaxes his inner muscles. He let go of his stout length, letting it rest on his scrotum and leaned his hips forward to aim into the toilet. "Hmmmm..." He coos, his eyes going floaty and his tail giving satisfied wags as he let those waves of relief course through him. Unfortunately, he didn't get to enjoy that for long. 

With his guard down in a potty break bliss, the older pup crept behind him and whipped the front of his waistband up, pulling his briefs taunt over his bulge and smothering his formerly free-flowing stream, instantly soaking through the thin fabric. 

"Ah!" He yelps, feeling a flash flood of pee invade the intimate spaces of his crotch. "No, no, stoooop!" The little brother pleaded, tugging on his sibling's bigger boy arms, but his cries fell on sadistic ears. "Mmf!" He let out a whine and squeezed his thighs together, attempting to clench his flow back. But his bladder had no patience left, and his raging stream resumed after a meager pause, loudly hissing underneath his darkened raining underwear, with multiple hot rivers branching down his legs. He was helpless but to just sink down and let it happen, shivering among the conflicting feelings of relief, wetness, and clammy heat on his most sensitive parts. By the time it ended, his face was wet with tears as well. His privates steamed in his completely soaked briefs, a rapid drip still falling off the tip of his bulge. He choked back sobs, determined not to seem more like a baby in front of his big mean brother. 

"Now we're even!" His brother released his underwear with a toothy grin, his own shirt dripping with urine. 

'Even!?' But his little brother had to go first! Those sad tears suddenly turned into ones of petty anger, as he spun around and sunk his teeth into his dumb, mean brother's arm. A screech, a punch, and the two were tussling on the floor in a puddle of puppy pee, much less playful than minutes earlier. In the end, neither won the battle as their parents broke them up and they were forced into a peace treaty bath.
