It was almost noon when Blake's workday began. The otter and his companion Finir stood ready in their wash cabin, waiting for their first client to appear. The two otters owned a washing bay for ferals, offering their paws to help those without them. Everybody with four legs and the need for a throughout cleaning was welcome, in exchange for appropriate payment, of course. Both males were already undressed, stripped down to their dark brown fur, so they wouldn't make a mess of their outfits during the cleaning. Eventually, someone approached and knocked on the door. Finir went to open and let their first customer in. A huge, hazelnut draft horse stepped into the washing bay, greeting the males with a happy neigh. 

While his companion closed the door, Blake led their huge client to the center of the room, the stallion's hooves clopping on the slatted wooden floor. By the looks of it, Maestro, as declared by a collar around his neck, had been working all morning. Marks on his fur where the bridle had been resting hours-long identified him as a carriage feral. A bag was hanging from his collar, keeping everything he needed within reach of his muzzle. His entire body was drenched with sweat, his fur glistening and damp, his legs covered with the dust and grime of the road, and he radiated a pervasive, masculine stench that quickly filled the entire room. The draft stallion was just another one of many sweaty, hardworking customers that perused their services. 

The large male's musk elicited an excited sigh from Blake. This was one of the reasons why he loved doing his job. Why he was doing what only very few others would do by choice.

While he still wallowed in the smell, Finir took care of business and showed Maestro a painted steel sign that listed all of the services the otters offered. The quadruped's eyes flicked over the shiny surface, his ears tilting as he compared the benefits of the services to his available budget. Once he made up his mind, a quick tap on the placard sufficed to clarify his wishes. The stallion requested a full service, everything the otters had to offer, and the companion's eyes met for just a moment to exchange a bawdy grin.

Blake grabbed a bucket of soap water and a brush and went to work where the scrubbing was needed the most. He dropped next to Maestro's hind legs and worked the sullied fur as hard as he could, loosening the crusts of solidified dust, sweat, muck, and grime. Part of the filth came off as crumbs, while the other part dissolved into the water and created an icky, muddy slurry. The frilly parts hanging over the worker's hooves, a hallmark of cold-blood horses like Maestro, were particularly dirty and required the most effort. Blake wasn't too fond of this part of his job, but it couldn't be all fun, could it? Luckily, his experience was hugely improved by the smell and the sight he was granted. The otter leaned against the stallion's powerful, muscled thigh. With his nose pressed against the sweaty fur, he inhaled musk-ridden air while staring right at his massive junk. The leathery sheath and the pair of hanging, bloated balls were an alluring sight, insignia of a strong, potent male. Just looking at them made his muzzle water and his mind cloud with arousal. Further down, his dick jumped up and swelled with blood in record time.

After the two otters had taken care of Maestro's hooves and lower legs, Finir in the front and Blake in the back, it was time for the best part of the full service. Before they cleaned everything else, they would first make the mess even bigger, and Blake would be right in the middle of it. Now, he would get really intimate with the male's magnificent bits. "Alright, that'd be the worst taken care of. Blake, honey, would you mind helping our big boy out? I'm pretty sure he's saved up a nice load for you."

"Of course. I'm already on it," Blake grinned and rubbed his paws. He gave the huge stallion a pat on the back, telling him to get down on his knees. Then he slipped under him and shuffled up to his sheath, greeting the sweaty fold with a deep huff. Maestro's potent stench filled his nose and his lungs, piercing right into his mind and flooding him with horny heat, drawing a horny groan from his muzzle. It smelled intoxicating and masculine, and Blake needed more. He greedily pushed his snout into the damp hole, nostrils flaring as he sucked its musky treasures up. The otter couldn't stop drooling, just spit running over his lips as he savored the potent cocktail of sweat, musk, leftover piss, and strong equine pheromones.

Finir joined him, kneeling behind his companion. He took a big, indulgent sniff and assessed with a trembling voice, "Shit, you smell amazing, Maestro." Then, he grabbed his buddy's head and pressed it firmly against the glistening sheath, forcing him to wrap his lips around the leathery skin. "Here, let me help you, honey."

The large stallion neighed jovially, enjoying the horny affection the otters showed him. His muscles twitched and tensed in eager anticipation. Hadn't he been down on his knees, he would've pranced around the box with excitement.

Blake grunted lustily as his buddy rubbed and massaged his neck, preparing him to swallow the stallion's piss. While this service was technically not necessary -- there were plenty of clean public toilets scattered about the town -- this part of their service had become quite popular for some reason. He groaned in surprise as the other otter suddenly pulled up his tail, spat on his asshole, and rubbed it in before pressing his half-hard chub against it. Before he knew it, Finir had sunk most of his shaft inside and let loose with a savoring sigh. Blake felt a wet warmth expanding in his bowels, hearing a soft hiss and a noisy splatter as his companion emptied his bladder inside him. He gasped into the sheath while Finir groaned,  "Ah, that's good. Maestro, please, go ahead. Fill that slut!"

Before Blake could say anything, the sweaty fold on his lips jerked and a strong, steady stream of musky urine rushed out of the dusky depths. His muzzle quickly filled with the pungent liquid and he had to swallow rapidly to have any chance of keeping up with the stallion's excessive output. The fluid rapidly coated his tongue and his mouth cavity as it gushed into his throat, splattering back into his nose and running over his lips. Despite his best efforts, he couldn't contain all of it, droplets falling from his lips and dribbling from his chin as he gulped as fast as he could. 

The dick in Blake's ass hardened as the other male watched him struggle with the flood. While he was still busy drinking piss straight from the tap, his buddy began to thrust with lazy strokes, panting his enjoyment right into his ear. "You really like being a toilet, don't you? A piss and cum dump for everyone who looks at you funny," he purred. "We would probably earn an even greater fortune if I tied you to the outside wall after work and let a bunch of random passersby take out their pent-up horniness on you."

Then, his partner suddenly pulled his face away from Maestro's sheath. The stallion snorted in surprise. He wasn't even remotely done urinating and he simply couldn't stop himself, pissing on and draining the remaining content of his bladder all over the otter's face. Blake sputtered and gagged as the golden stream hit his open muzzle, showering his entire upper body while his companion chuckled with horny glee.

Maestro sighed with deep relief once he was done peeing and the last drops escaped his sheath. While he stood back up, the otters seized the opportunity to give him an impromptu intermittent show, momentarily delaying the cleanup. Overwhelmed by lust, Finir bent Blake over and went savage on his ass, fucking him with all he got. The horny, piss-soaked otter quickly lost himself in a flurry of lust and arousal, howling as his buddy rawed his ass while their customer watched them with shameless interest.

A lewd part of the stallion soon graced them with its presence. A thick, pink and brown mottled horsecock had flopped out of Maestro's sheath and dangled down in front of Blake's face. Once the lusty otter noticed it, he instantly grabbed it and guided the flat tip to his lips, kissing and licking the glistening surface. He pushed his tongue into the damp cumslit and sucked on it, drinking the mixture of musky sweat and salty pre from the leaky hole while stroking the throbbing shaft with both paws.

Finir wrapped a paw around his companion's cock and jerked him off while he hammered his hole, bringing them both closer to a mutual orgasm. A few more hard thrusts and the otters came one by one. Finir's muzzle opened and he filled Blake's ears with a husky howl while he buried his cock deep inside his ass and unleashed a big, wet load. His twitching dick and frenzied stroking rapidly triggered Blake's climax, who squirted his nut all over the slatted floor, right into the shallow puddle of horse piss underneath him.

"Alright, sorry for the holdup, Maestro. I just had to take care of something," Finir apologized, pulled out of his buddy, and slapped him on the butt. He pulled Blake back on his feet and led him to a sturdy breeding rack. With some assistance, he helped him climb onto the contraption and restrained him with several straps around his limbs and tail. Then he pushed the rack and willing victim next to the stallion and connected it with a few hinges in the floor. "And now he's all yours."

A burst of excitement rushed through Blake's chest as he was presented to Maestro, mentally preparing to be mounted by the massive male. His loosened rosy anus twitched and squirted otter cum and piss as he eagerly welcomed the imminent wrecking. "Yes, now I'm all yours, stud."

Maestro appreciated the sight with an exultant neigh, prancing and sidling about before he actually moved behind the restrained otter. A loud bang echoed through the room and rang in Blake's ears as the male jumped onto the rack and plummeted onto the cushioned struts. The breeding rack groaned and creaked under the immense weight. It gave a little but didn't break. Seconds later, the flat head of the stallion's humongous prick kissed his sphincter, throbbing and leaking all over him, ready to go in. 

However, Maestro was simply too excited and eager to align himself properly. Instead of pushing directly against the otter's loose asshole and slowly working his way inside the tiny ring, he just slammed the tip against Blake's butt without rhyme or reason, again and again. However, the otter's anus was still too tight to simply yield to the massive horsecock, so the stallion just ended up pummeling Blake with the full force of his hips, tenderizing his butt with massive slaps and shoving his tail around. This impressive demonstration of raw strength made Blake groan and grunt with helpless joy. This was a great foretaste of what the horse would do with his insides.

After watching the feral male's struggle for a bit, Finir finally decided to step in and lend him a paw. He patted Maestro's flank insistently until he calmed down enough to listen and allow him to grab his wang and guide it to Blake's pucker. "Hoo, give me a moment to help you, will you? Here, just like that," he whispered and pushed the horsecock against his partner's tailhole. "Now you push forward, but just a little." 

The pressure on Blake's ring rose rapidly, and suddenly his sphincter gave in with a noisy, wet slurp and gobbled the fat tip right up. He wheezed as the throbbing, hot meat forcefully pulled his rectum open. His pucker was now stretched wide and bow-taut, and he could feel every throb and twitch of Maestro's cock. "Fuck, you're big," he blurted out, his hands cramping up while he tried to deal with the insertion. And he knew full well that this was just the beginning.

"That's it, you're inside him. Probably can already feel how fucking tight my slut is, can't you? But not for long," Finir snickered raunchily. "Go for it and don't hold back. He likes it rough. Nothing makes my sweetheart here happier than a fat cock forcefully rearranging of his insides, am I right, Blake?"

"Uh-huh," Blake affirmed, gradually failing to think coherently as the insertion made his mind devolve into a horny mess.

The other otter gave the stallion a pat on the butt and the hulking mountain of muscle began to move with a thundering snort. Maestro eagerly pushed his tool into the tight male. The very first thrust went already deep inside the otter, smushing his prostate and filling him with hot, throbbing cock meat. The relentless stretching activated all the nerve endings inside him at once and sent an incomprehensible flood of stimulation to his brain. Blake went cross-eyed and his tongue flopped out of his muzzle as his jaw refused to close. Almost all air escaped his lungs in a single, drawn-out cry, his limbs slackened, and his tail fell down, drooping over the stallion's steaming wet horsecock.

Soon, the draft horse reversed his thrust. He forcefully pulled back before instantly plunging back in, shoving his cock a little deeper than before. Without granting Blake even just a second of rest, Maestro continued to thrust into his ass, gradually increasing the pace as he broke him in. The noises of the penetration were as loud as they were obscene, gross slurps and wet squelches accompanying the steady foray on his poor asshole. The little male quickly lost himself in screams of pleasure, the pitch constantly rising and his voice swelling with lust as Maestro fucked him with feral vigor. Every thrust crashed down with relentless might, shaking his entire body and mind, and telling him loud and clear that he wasn't in control anymore. Blake was so full and helpless right now, nothing more than the horny stallion's cock sleeve, his toy, and he loved it.

The joints of the abused rack creaked and clattered as Maestro thrust deeper and deeper, going harder and faster until he had seized all the room he could claim. The stretchy otter's body had limits that not even years of experience could circumvent. The horse only managed to fit in half of his gargantuan schlong, but he used that part as best he could, pounding his tight, howling cock sleeve hard and thoroughly. Every single one of the stallion's thrusts stopped with a resounding thud as the flat tip smacked against the top of Blake's guts, hammering his diaphragm and completely overwhelming him. Air entered and escaped his lungs in sync with his partner's thrusts, his howls and squeaks fully controlled by the rhythm of the pounding. 

The stimulation was getting even worse as more and more nerves joined the chaos, flooding his brain with raw pleasure and supercharging his lust. No training in the world could prepare him for this. His vulnerable little mind just wasn't made for such abuse, and it rapidly deteriorated and crumbled under the savage assault. There was no up or down, no past or future, just the omnipresent, overbearing sensation of the fat, throbbing horsecock ravaging his insides. Maestro was fucking him completely silly, and he had only just begun the pounding, still far from reaching any climax.

Piercing neighs, lusty whinnies, and deafening snorts filled the air as Maestro bred Blake like a mare in estrus, pumping his rod in and out with feral force. All muscles in the male's body worked together toward the same goal, cumming into the rapidly loosening otter hole. Sweat ran down his flanks and his stench had grown even heavier, rank with the odor of sex. The sight and smell were strong enough to lure their watcher into the obscene union.

Finir stumbled closer and hugged the stallion's left leg with one arm while he buried his muzzle in his taint, greedily inhaling the Maestro's pervasive scent. His tongue darted out and flicked over the glistening, dark skin, and he licked the sweat right off. While the horse ceaselessly wrecked his companion, he eagerly worshiped his delicious backside and jerked off to the smell, the taste, and deafening sounds of vigorous sex.

The little otter was tighter than any mare, and Maestro could only keep up the frenzied pounding for so long. After just a few minutes, the male succumbed to a powerful orgasm. His tip swelled and flared up inside his clamoring cock sleeve, grinding the thrusting to a halt as it fattened enough to form a seal with Blake's insides. Finally, his urethra opened, his balls tensed up, and he unloaded a volley of voluminous spurts of thick, hot horse semen, the mess rushing into the smaller male with an obscene gurgle.

Screwed completely silly, his brain flooded with pleasure, Blake barely even registered what was going on. Before he knew it, the vigorous pulsing, twitching, and sloshing in his swelling belly triggered his own orgasm. His penis bounced and twitched violently as he unloaded rope after rope onto the slatted floor and drained the last bit of air from his lungs with a blissful howl.

Blake's climax was powerful but short-lived. As soon as the all-encompassing high diffused, he began to recover from the insane romp. His pounding heart slowed and his rattling, shaky breath normalized. And yet, the horsecock stuck inside his ass was still not done. It kept pulsating, pumping, and twitching, and mercilessly inflated him with more and more semen until there was enough inside him to turn his belly into a taut, sloshing ball of cum.

However, all things must come to an end eventually, and even Maestro's full, heavy breeding orbs ran dry after a minute of cumming, the spurts fading to a weak trickle. The flare inside Blake's guts recovered and allowed his huge partner to pull out. Not that the otter noticed much of a difference. Everything below his waist still numb, tingly, and stretched to its limits. He only heard the nasty slurp and wet pop as the horsecock left his ass.

Bloated and full with cum and piss, the overwhelmed otter could barely move a finger, much less climb out of the rack. Thankfully, his companion joined him and allotted him some new work. "Fuck, he really filled you up, didn't he? Come, honey, I'll give you something else to do. But first..."  Finir took care of his own urges. Without any warning, he grabbed Blake's head, pushed his rigid cock against his lips, and rammed it into his muzzle. The restrained male was too exhausted to complain, and simply embraced the short but intense face-fuck. A few hard pumps and his partner bust a nut in his throat, feeding him a little more cum.

"Ah, I needed that. Now, come." Finir grabbed the rack and pushed it behind the stallion, aligning his buddy's muzzle with Maestro's swollen, dark brown pucker. Then he took the largest butt plug he could find and plugged Blake's gaping, battered asshole. Only then, he loosened the restraints so Blake could help himself to his reward. "Here you go, some sweaty, musky horse ass. Have fun, honey."

Blake needed no further encouragement. He clumsily pulled his paws out of the restraints, reached around the stallion's huge rear, and dug right in. He kissed, licked, and sucked Maestro's puffy pucker, and relished its earthy, musky flavor with bawdy groans. The taste alone made him hard again in no time, his throbbing tip perpetually leaking pre on the ground. While he washed and cleaned the horse's backside with nothing but his ravenous tongue, his companion took care of most of the actual work. The otter grabbed a bucket of fresh soap water and a brush and started to clean and scrub the massive stallion, a pretty daunting task, but one he had done many times before.

Soon, Maestro looked prim and proper again. The cleaning was finished. His masculine scent was softened and masked by the scented soap, his fur shimmered in the light and was neatly groomed through extensive treatment. Meanwhile, Blake had turned into the complete opposite of clean, his body swollen with fluids, his fur damp and reeking of sex and horny stallion. 

Now that they were done, Finir helped him down from the rack but didn't grant him any rest. His buddy immediately forced him to his knees and casually used his throat to relieve some more pent-up horniness that had accumulated from the sweat-inducing work. But Blake didn't mind. His companion was the more articulate and business-minded of the two, taking care of the cleaning and business, while he was the slut and cum rag, who gladly took care of the sexual urges of the clients and his companion whenever he could.

Maestro seemed highly pleased with Blake's and Finir's work and blessed them with a happy neigh as paid for the service, giving them a fat tip for their effort. He then gave each of the otters a kiss on the cheek and slowly walked out of the washing bay. Blake's eyes followed him on his way out, catching one last glimpse of his majestic backside before the stallion left to continue his daily work. Another satisfied customer who would undoubtedly return one day.

Once Maestro was gone, Finir bust another nut and pulled out. Then he heaved Blake over to a little shower in the corner and quickly rinsed him clean. Before too long, there was a knock at the door. The next customer had arrived and waited to be served. "Ready for another round, honey?" Finir asked with a saucy grin.

"Always!" Blake slurred in response, excitement welling up inside him. Hopefully, they ordered the full service as well.
