Abaco burst from the water's surface with enough speed to launch himself a short distance into the air amidst a spray of droplets. The orange and white Suicune landed gracefully on the grassy shore by the lake he had just exited, his mint-green mane flowing back from behind the matching crest on his forehead, his wavy ribbon-like tails twisting forwards to float by his sides as he came to a stop. Despite having just emerged from the lake, no water dripped off of him; his body simply absorbed it.

Turning around, he walked back to the edge of the lake, its mostly smooth surface glittering in the late afternoon sunlight. He lowered his head to drink a mouthful of water, nodding in approval afterwards; the lake's waters were crystal clear now, purified by the legendary Pokemon's powers. "Perfect," he muttered to himself, before raising his head to glance up at the sky. It was getting fairly late, so that would have to be enough for one day. The human settlements nearby had their own industry and agriculture, and all the pollution that came with it, tainting the otherwise pure and pristine bodies of water in the region. It fell to Abaco and his other family members to spend much of their time undoing that damage, filtering vast volumes of liquid with cleansing them of chemicals and other pollutants.

He began the trek throughthe rainforest back to his home, such as it was. Technically, the entirety of Polaris Cay was his family’s home, a picturesque tropical island out in the ocean, blessed with lush rainforests, numerous fruit trees, a tall mountain, and wide beaches. The island got its name from a curious quirk: anyone could always see the north star from the island in the night sky, no matter the time of year or season.

The typical resting place for Abaco and his family after long days of their thankless work was an overwater bungalow. Originally a fleeting attempt by humans to tame one of the island’s pristine lagoons, it had long been forgotten and abandoned years ago, until the Suicunes had reclaimed it from disrepair. But, there was one particular part of it he would always return to each night, and that was where he was heading to, striding between the trees and occasionally casting his gaze towards other nearby wild Pokemon. He towered over most of them, and they knew not to mess with a legendary Pokemon like himself. Most wild Pokemon revered the Suicunes on the island, keenly aware of how integral they were to life on it. Furthermore, the few who had foolishly challenged the Suicunes had all been quickly defeated and left on the ground in a faint.

The journey did not take Abaco long to complete. Deep in the rainforest he came upon the large, fallen log by a clearing that he had claimed as his own, but someone else was already there by the time he arrived, sprawled on his side with his forelegs resting on the leg. Another Suicune, Frangipani, shared his father's bright orange body coloration. However, his mane was bright pink, fading to a magenta color close to the tip. In addition, the other male's crest and tails were both yellow, fading to orange at the tip of each, as was the half-hard canid cock hanging from the massive sheath between his legs.

"Took the scenic route today, did we?" Frangipani teased as his father entered the clearing.

"I was just enjoying the waters of the lake on the western side," Abaco remarked, his eyes glancing between Frangipani's legs. Although Abaco was certainly a well-endowed male, his son had outgrown him by the time he had become an adult, a fact that Frangipani enjoyed reminding Abaco of at every opportunity. "Could barely wait for me to get back, hm?"

The younger Suicune raised a rear leg to show off more prominently, proudly displaying himself to his father. "It's the highlight of my day," he replied. "I got back quick enough to have some time to think about what I'd like to do tonight."

Abaco walked over to Frangipani and sat on his haunches, a pose that allowed him to display himself to his son. He spread his legs to reveal his sheath and the pink tip of his cock that was peeking out from it, his balls resting on the mossy ground under him. "Just so long as you properly purified the waters around here today," he reminded Frangipani.

Frangipani gave a small laugh, his gaze drifting between Abaco's legs. "Of course I did, Little Aba," he teased affectionately, lowering his leg and starting to stand up. "In fact, I probably did a better job than you," he added with a smirk.

"Is that so?" Abaco responded, raising his muzzle at the challenge. "It isn't a contest."

"I know, I know... but I did have an idea for one," Frangipani remarked as he got to his feet and padded over towards Abaco, sitting in front of him. "You haven't pissed anywhere since this morning, have you?"

Abaco tilted his head and grinned, having an idea of where this was going. "No, I haven't. You know my routine."

Frangipani nodded. "Good. I have a challenge for you! Why don't we see who is holding more, hmm? Whoever pisses for longer wins."

"Wins what?" Abaco inquired with a smirk.

"The loser's ass," Frangipani remarked, winking. Rising to his feet again, he turned around and wiggled his rump towards his father, flaunting his rear, as well as the heavy ballsack that was bouncing between his legs. "I bet you'd like a shot at this, wouldn't you?"

It was a very tempting offer, one that made Abaco hum deeply, his cock slipping a little more from his sheath. "You’re on, big boy. I hope you're ready to get pounded."

"We'll see about that!" Frangipani teased, turning his upper body to look back at Abaco with a grin. He walked over to the edge of the clearing where there was a large, mossy boulder sticking out from the ground. Once there, he cocked a rear leg, partly to get into position and partly to flaunt his endowments to his father once again, his dick hanging from his sheath while his balls rested against his inner thigh. "I'm ready when you are."

Abaco chuckled as he got up and leisurely strolled over towards his son. "There’s no need to rush your defeat," he taunted playfully, taking his time as he got into position on the other side of the rock. "You like showing that cock of yours off, but remember who gave it to you."

Frangipani was unfazed, grinning widely. "Jealous, Little Aba?"

"Not when I have you all to myself," Abaco admitted with a smirk, finally raising his rear leg upwards, his shaft hanging halfway out from his sheath. He glanced back, able to see the loins of both of them, his son's extra size undeniable with the two of them side by side like this. "All right, big boy. Show me what you can do."

"Heh, gladly," Frangipani said confidently. "Ready, set... go!"

The two of them began pissing at the same time, or as closely to one another as made no difference. Two thick and heavy pale golden streams gushed out from their cocktips parallel to each other as the Suicunes began relieving themselves. Abaco's urine splashed almost directly down to the ground, while Frangipani's piss struck the bottom of the boulder on account of his half-erection, darkening the stone’s mossy surface immediately. The air around them was filled with the sound of liquid splashing, from both the pattering of Frangipani's piss on the rock and Abaco's on the ground, quickly forming a puddle that his stream splashed into.

Frangipani let out a loud and exaggerated sigh of relief as he watched the two streams of piss gushing from them. "Ahhhh, that's good. I've been soaking up water all day, and it feels great to finally let it all out."

"Mmm, likewise," Abaco agreed placidly, his cock twitching as it continued to emerge from his sheath as he enjoyed the sight and the relief he felt. Being two legendary creatures of water, their capacity for their particular element was immense, both of them pissing out a full pint of liquid every five seconds or so, with no signs of stopping. His emerging shaft brought his stream closer to the boulder, splashing in the puddle growing around it. Chuckling in amusement, he murmured, "I was in the lake for so long, I might have brought most of it back with me..."

"We'll just have to see if that holds up to my swimming all the way upriver," Frangipani fired back with a grin, wiggling his hips. He was enjoying the show just as much, glancing between his loins and his father's, comparing the two and reveling in being bigger in every way. Both from the immense relief washing over him and from the lewd display, his cock started to stiffen the rest of the way, the twitching length making his stream splash across the rock, staining more of the stone’s surface. Enough Suicune urine had gathered at the base of it that it was flowing all the way around to the other side, unable to soak into the ground faster than the two males could piss it out.

Pints became gallons as the two of them continued to relieve themselves, giving soft sighs and groans of satisfaction. The big puddle around the rock spilled off deeper into the rainforest, the start of a new – if temporary – yellow river of piss. Frangipani did not take long to become fully aroused, his stiff cock making his piss come out in a harder, narrower jet that sprayed off the rock in a shower of droplets, and Abaco was not far behind him. Soon, both of their shafts were throbbing under their bellies, the urethras swollen out from the heavy streams of piss gushing through them, their uninflated knots out in the open, balls hanging and swaying slightly from the subtle movements of their bodies as they kept their balance on three legs.

"Are you enjoying this contest?" Frangipani taunted, raising his voice slightly over the sound of splashing urine. He wiggled his hips to make his cock bounce, splashing piss all around the rock as he went on, "Or are you turned on by the thought of having your son's huge cock buried in your ass?"

"I'm just looking forward to being on top of the family stud for a change," Abaco remarked with a smirk. He took a quick glance forward; the gallons and gallons of urine they had pissed out were flowing even further into the rainforest, spreading out across the ground a little, and he lost track of the winding yellow river among the trees.

"Could have fooled me," Frangipani teased, "Especially since I think my victory is getting close..."

Abaco looked back, comparing their streams; Frangipani was still going strong, but Abaco himself was starting to gradually lose strength, his stream coming out in an arch rather than a hard and straight jet. Unfazed, Abaco kept his breathing steady, hoping that he might outlast his son yet, but it was for naught; the arch of his urine continued to wane, soon becoming a dribble onto the ground underneath him just as his son's stream showed the first signs of running low. Abaco clenched and tried to get out what he could, managing just a few more spurts, but after the third clench he was completely dry.

"You lose, Little Aba..." Frangipani remarked with a chuckle, his ribbonlike tails dancing triumphantly as he continued to empty himself the rest of the way. He gave another satisfied sigh, both from winning and from the relief, watching his father lower his leg, while Frangipani's own stream slowly came to its conclusion – though each final spurt of the Suicune's urine as he clenched his muscles was still a cup of liquid at minimum.

"So it seems," Abaco said as he conceded, grinning in excitement. The older Suicune stepped away and back to the fallen log, resting his forepaws on it, lowering the front half of his body as he hiked up his rear and spread his legs submissively. "Come over and claim your prize, big boy..."

"So quick and eager to raise your tail! If I didn't know any better, I'd suspect you wanted to lose from the start," Frangipani said teasingly, lowering his leg and walking up behind his uncle, admiring the other Suicune's cock and balls. He reared up and put his forepaws on his father's rump, shifting closer, sliding his erection underneath Abaco's body to rub his yellow cock against the pink length of his father. "Do you submit this easily for every male, or just for me?"

Abaco gave a flustered huff, his cheeks flushing a deep crimson. "Are you going to mount me or not, stud?"

Frangipani leaned forward, shifting his hips back and then forward again to line his cocktip up against Abaco's tailhole, nudging the ring of muscle with his hard flesh, leaking a little precum against it. "I'm the one in charge here, Little Aba," he asserted in a playful yet dominant tone. "We'll start when I'm good and ready."

Abaco's claws dug into the fallen log as he felt his son's cock teasing at his back door, and he drew a deep breath, trying to relax. "And how long will it take you to-"

He let out a gasp as Frangipani interrupted him mid-sentence by applying enough pressure to start penetrating, making the pair groan aloud together as the younger Suicune slowly but gradually slipped more and more of his hard flesh into his father's clenching anal tunnels. Abaco's toes curled and he dug his rear claws into the ground as Frangipani penetrated deeper, sliding in little until that yellow knot was pressed up against Abaco's rear entrance.

"What was that?" Frangipani asked rhetorically as he ground lightly against his father's posterior.

"N-Nothing," Abaco mumbled, feeling the heat of his son's hard flesh stretching out his ass. The smaller Suicune’s pink shaft throbbed in anticipation, already drooling a thick bead of precum that clung to his pointed dick tip.

"That's what I thought," Frangipani asserted, moving his front paws to Abaco's shoulders and holding him down. He only made very slow, shallow movements with his hips, however; despite his dominant attitude, he didn't want to hurt the Suicune his cock was buried inside of, and gave Abaco some time to adjust to the girth spreading his anal tunnels.

Soon enough, he pulled back further and began to thrust in earnest, even if his pace was still gentle. Both of them moaned out together as Frangipani's hips slapped against Abaco's, the younger Suicune's uninflated knot pressing up against Abaco's familiar sphincter. Frangipani's balls swung on each thrust, bumping lightly against Abaco's smaller but still impressive and plentiful orbs, the pair panting for breath from arousal and, in Frangipani's case, exertion.

Abaco kept a tight grip on the log as his son gradually picked up the pace, bracing himself and holding his body as steady as he could. As Frangipani leaked more precum into his father, he was able to thrust a little faster, slicked by his own fluids, making both of them groan in pleasure. His virile nuts slapped lightly against Abaco's sack on each inward thrust as he properly pounded his father's rump, the force of his thrusts making Abaco's shaft bounce underneath him, sending little bursts of precum flying all over the ground below.

Both of them panted and moaned louder as they continued, Frangipani savoring the tightness of his father's anal walls while Abaco reveled in the feeling of his son's cock plunging into him again and again. The clearing was filled with the sound of Frangipani's hips meeting Abaco's ass, as well as their pleasured moans and fervent gasps for breath. The younger Suicune kept a firm hold on his father as he drove his shaft into those squeezing walls, eyes shut tight from the ecstasy he was reveling in. Even though both of them were quite promiscuous, Frangipani particularly adored the velvety tightness of the older Suicune's plush and wet rectal walls. No other male that he’d pinned under him felt nearly as good, and each thrust of his father’s hips back against his own reminded Frangipani of why he loved burying his cock in that indescribably pleasurable tailhole so much.

But then as he moved back and forth, pounding away at his father's ass, his knot knocking against Abaco's back door, he felt the older Suicune shudder under him and heard him moan out louder. Abaco was trembling in climax, and Frangipani heard the splattering of ropes of Suicune cum against the ground underneath them as his father blew his load. "You love this forbidden buttsex, don’t you, Little Aba?" Frangipani gasped out between heavy breaths, not far behind him.

"Yes!" Abaco moaned out needily, eyes shut tight from the orgasm coursing through him, rocking his hips to push back into his son's thrusts. "Yes, I love it! And I will never stop craving it!"

"Aah... and I... love it too...!" Frangipani forced out as he felt his climax approaching, shoving his hips harder into his father's rump. He felt that clenching hole start to give, and with a final shove, his knot popped in through the ring of muscle and was surrounded by Abaco's tight, warm walls. Frangipani succumbed to his orgasm and let out a deep, satisfied groan that mingled with his father's moans from being knotted, the yellow bulb of flesh swelling out just inside of Abaco's ass as Frangipani came hard.

Abaco moaned out louder, shuddering heavily from the surge of heat into his body. Each heavy throb of Frangipani's shaft was accompanied by an eruption of thick, hot cum, and the younger Suicune's knot ensured that not a single drop of it went back the way it came. The two virile balls resting against Abaco's pulled up again and again as they unloaded into the older Suicune, pumping so much of Frangipani's seed into him that by the time his son's climax had ended, Abaco's belly had swollen out slightly to contain it all.

For a little while, the only sound in the clearing was the two Suicunes panting heavily, both basking in their afterglows and recovering from their intimate moment. Frangipani rested on top of his father, thoroughly locked in place by the knot lodged in Abaco's tailhole, his paws loosening their grip and sliding down to hold Abaco in a gentle and tender hug. Abaco hummed softly, gently reaching down with one paw to rub over his swollen belly, enjoying the warmth filling him from his son's potent orgasm.

Eventually, Frangipani lowered his head and nuzzled at the side of his father's neck. "Hey," he murmured, getting his father's attention.

"Mm?" Abaco responded, shifting slightly, giving a little clench around the knot lodged in his ass.

Frangipani shivered a little bit, but just gave Abaco another gentle nuzzle. "Thank you," he said quietly. "Life wouldn't be the same here without you. I love you."

Abaco gave a smile, doing his best to nuzzle back to Frangipani's head. "And I love you too," he replied between breaths, his ribbon tails reaching up and loosely wrapping around his son's body affectionately.
