“The Benefits of Pet-Sitting" - Story by Kaz

Chapter 1: Unique Tastes

Rush wasn’t your average anthro. Granted, in a world of unique hobbies and animalistic impulses there weren’t too many ‘average’ anthros. Still, Rush stood out even from most of the others. His appearance wasn’t anything strange, just a very tall and athletic Great Dane. Black all over with a white underbelly cut into two sharp triangular markings on his belly, along with ‘socks’ and ‘gloves’ style markings on his wrists and ankles. Floppy ears, like those of border collies added an endearing cuteness to his profile. No, it wasn’t Rush’s appearance that set him apart.

Nor was it his job. Rush worked as a delivery courier for a popular app-based food ordering service. It was something of a ‘gig’ but he also specialized in drawing art for pay on the side. His commissions weren’t wildly popular, but they were known enough to bring in a decent chunk of side change. Lots of anthros did things like art and story commissions.

His apartment didn’t make him stand out, not even to his neighbors. Rush kept to himself for the most part and wasn’t a partier. His one bedroom apartment in a standard residential tower was a bit messy if anything but he wasn’t a slob or anything like that. No funny smells, sounds or sights for his neighbors to pick up on.

Perhaps his hobbies then? No, there wasn’t anything out of the ordinary about hiking and running. Having exercise as a hobby was a very modern thing to do, and being alone with nature helped ease Rush’s thoughts. He enjoyed playing video games sometimes like any other young anthro these days. What could it possibly be that made him so unique? Ah right...his obsession with dogs.

Rush had always been fond of his feral canine counterparts. At first it had been a sort of childlike curiosity in something so similar to himself yet so different. As he grew older though, he began to notice different qualities in this canine companions that drew his attention. The way they strutted around fully nude with no shame, their exposed packages bouncing and bobbling for anyone to see. The way they didn’t think twice about humping someone’s leg or another stray mutt if the urges called. He found himself utterly fascinated with their freeing sexuality and it led to a rather unhealthy obsession with canine anatomy.

Being canine himself, Rush was sporting the requisite pink and purple mottled flesh dog dick. Complete with a sheath and even a decently sized knot he began to familiarize himself with canine anatomy from a young age. However there was something more primal and uncontrollable about the feral dogs...Even the way they’d lipstick wildly whenever they became slightly aroused, or the watery precum that’d flow like fresh water from a faucet. His own dick never did that, and it felt very mundane.

Of course, such an obsession didn’t develop without exploration. It wasn’t enough to google search things like ‘dog dick’, ‘horny dog’, ‘knot sex’, ‘dog cum inside’ and similar terms. The images and videos only further stimulated his cravings. First came the toys. There was no shortage of companies that specialized in silicone penetrative toys modeled after animal anatomy. In a world of anthros it was as commonplace as anything. It started honestly enough, with just a few toys. Rush found that he couldn’t control himself however and soon he had more toys than he knew what to do with. Some huge, some medium and even a few small ones. Different shapes and textures, some with terrifyingly large knots. It was a menagerie of dog.

After the toys came memorabilia and decor that focused on the sexuality of dog. Hand made tapestries, a beautiful colored glass bong and even random knick-knacks. It wasn’t long before his adult life became overtaken completely by this fierce obsession. He became something of a recluse, no longer having friends come over. He’d spread his obsession out thoroughly through his apartment and every room held blatant signs of dog-fucking supremacy. He was all but shouting “I’m a zoophile!” to the masses.

Eventually the self-toying and fantasies became boring for him. He’d spent so long staring at the shapes and sizes of dog penis littered around his home that he was growing tired of it. He needed more, he craved the thrill that could only come from experiencing the next level. He knew this would require some advanced research of course. One couldn’t just buy a new pet dog for fucking or anything like that. He began browsing his local social media for mentions of homeless dogs. As he clicked through the posts, he noticed that one particular shady part of the city seemed to be a hotbed for activity...

He’d set out on his mission one calm summer evening, driving across town to a place he’d normally never visit. Boarded up buildings, the sound of shouting in the distance and broken glass littering the sidewalks told the story of the seediest part of town. Even businesses couldn’t survive here. Luckily for him, that meant he’d have privacy for what he had planned.

Part of his obsession had led him to dark places on the internet, places where you could buy anything you wanted. For example, rubbings and drippings from female dogs in heat. The kind of stuff that would drive un-fixed mutts wild with primal urges. Now, he knew these dogs weren’t just going to come strutting up to him all friendly like. He’d come prepared with fresh food and treats. He just hoped for his sake that they weren’t going to tear him to shreads. So many things could go wrong with his little experiment...he could lose his life, dignity or even both. The cravings wouldn’t allow him to stop though.

Rolling up to a particularly dingy alley, he spotted a beautiful labrador nosing around the dumpsters in the alleyway. It was a hellhole. The labrador wasn’t particularly strong-looking but his tail bobbed and wagged with frenetic energy. There was plenty of life left in this dog. Rush remembered that first nervous step out of the car – the labrador had turned enough to give him an uncensored look at bouncing, bulbous balls swaying alluringly below a rather plump sheath. Gods, how exciting!

The labrador noticed Rush’s scent almost immediately and perked up in alarm mode, baring its teeth and stepping back further down the alleyway. Rush sucked in a breath and made sure he had everything, beginning to approach the alleyway. He’d stopped about twenty feet from the dog, hearing the warning tone in its growls that told him not to get cheeky. He spread out a worn blanket and set down his bag of goodies, praying to some unknown god that he wasn’t about to be mauled in a back alley.

Once the food came out, the labrador seemed to have a change of heart. Fear and malice turned to curiosity and hunger. The tail was wagging as the dog tentatively approached Rush. It wasn’t long before the lab was hungrily chowing down on the fresh meal, nosing at Rush for a second helping afterwards. Thankfully Rush had found a friendly stray, one that perhaps had recently been thrown from its home. He delighted in the attention and treats, and it wasn’t long before Rush was naked from the waist down, gripping the grungy blanket with tears streaming down his face as he got brutally fucked by a stray dog, mercilessly fed inch after inch of fat rocket.

Over the next few weeks he’d go back, revisiting his new friend. Always around the same time, and he always brought more food than one dog could need. Still, it warmed his heart to see his new friend eating his fill and seeking out Rush’s affection. Always ending his visits with a sore tailhole and a bowel full of hot dog cum, the watery fluids even leaking out and running down his inner thighs. He almost always smelled like a wet dog anymore, mixed with a starchy smell that only semen could produce.

And so Rush’s obsession started as a simple curiosity and unchecked had flowered into this monstrous life-consuming thing. He was going twice a week to get bred by a stray dog, coming home to smear dog cum into his fur and fuck himself senseless with dildos of every size. He was a knot bitch, and a very happy one at that.

The unpredictability of gig culture meant that there was bound to be a slowdown. And of course it hit hard in the early months of Fall one year. Rush found himself in need of some quick cash to handle a few forgotten bills, and he wasn’t quite sure what to do. He checked into the other courier related service apps around with no luck, finally resorting to the local ads website in the hopes of finding a quick and easy payout.

Scanning the entries on the simple website, he flipped past countless landscaping requests, babysitting needs and a few elder care options. His nose wrinkled as he scrolled and scrolled, but he felt his heart jump into his chest as he read the title for one of those posts. ‘Dog Sitter Needed – Will Pay Exorbitantly’. What kind of people would word an ad that way, he thought to himself.

His heart started to beat faster as he began reading through the advertisement. It seemed that some extraordinarily wealthy couple in the best part of the city needed to go on a short-notice vacation for a few days. They had made arrangements for their pet in the past but such short-notice during the busy Fall season meant that there was nobody to take him in and look after him. The ad read with such politeness and almost desperation that Rush couldn’t help but hurriedly tap on the reply button. Especially noticing the amount was four times what he currently needed to make ends meet.

As Rush typed in his response, mentioning that he had a ‘wealth’ of experience caring for dogs he couldn’t help but let out a deviant snicker. Sliding a finger down into his underwear to rub against his tender, slimed over tailhole he pulled it away and lapped at the dog cum residue he’d left there from the previous evening. Oh, he certainly had a wealth of experience. And he was going to get paid to sleep with this dog, very handsomely. If only he could have known something was terribly amiss with this listing...

Chapter 2: Pure Bliss

Rush spent the day after applying for the pet sitting gig on pins and needles. He wasn’t sure if he’d get the spot. Surely for that amount of money more than a few people had applied, right? He didn’t exactly have credentials or anything like that so he wasn’t too confident he’d get chosen. Still, if he wasn’t picked for the job at least he had his stray friend to look forward to. He was beginning to think he might adopt the boy.

It was late afternoon the day before the pet-sitting gig was set to begin when Rush’s phone went off with a text tone. The speed at which he unlocked his phone and opened his messages was incredible to say the least. He’d been lounging around his apartment with a TV show on, idly contemplating another knotting session with his biggest toy.

His eyes scanned the message frantically and he let out a whoop of delight as he processed the news. He’d actually been chosen to pet sit for the rich couple! They texted that they were impressed with the thought he’d put into the application and were sure he’d be the perfect fit for their precious boy. Rush’s fingers trembled as he tapped back a response thanking them and requesting the address.

He let out a long sigh of relief as he set his phone down and closed his eyes. Soon his money troubles would be over! And he might just get a fat load up his ass for his trouble as well. He couldn’t think of a better way to spend a couple of days. He shook his hands eagerly and looked around. Was he even going to be able to sleep before it was time to head out the next day?

Rush spent a good portion of that afternoon riding his favorite extra large knotted toy, relishing in the stretched out feeling it gave him and the immense pressure he felt when the knot locked in. He always took his time with his toy sessions, flipping through photos and videos he’d taken with his stray friend in the alleyway to really maximize the fantasy and pleasure.

When it was finally time for bed, he indeed collapsed into bed exhausted from the day. His emotions had been running high since getting the text back, and then adding on the toying session he had was enough to drain anyone. He slept like a log, drifting off into pleasant dreams of what was to come the next day.

He jolted upright for his alarm the next day, having set it with just enough time to shower and prepare for the trip. He scrambled out of bed and rushed to the bathroom, not wanting to even risk the possibility of being late due to traffic or something. Once he was freshly showered and dressed, he grabbed a duffel bag and grinned while packing ‘the essentials’. One huge bottle of silicone lubricant, an extra throwaway towel and a change of clothes. He was only supposed to be pet sitting for two days after all, so there wasn’t really a need to pack many clothes.

He contemplated packing his favorite toy in case the dog turned out to not be in heat, or incapable of having sex for some other reason. Something told him that he wasn’t going to need it. So he zipped up his packed duffel and checked his pockets to make sure he had everything. Wallet? Check. Keys? Check. It was now or never.

As Rush started the drive to the address he’d input into his GPS, he had to fight with himself not to speed or break traffic laws. He gave himself a little pep talk, reminding himself that he’d have plenty of time alone with the dog soon enough. No need to put himself in danger for a quick thrill. Still, it was a powerful urge to repress.

As the scenery began changing from apartment buildings and small houses to ritzy downtown business districts and rolling hills, he took a deep breath. The GPS showed that the address wasn’t far now. Into the ritziest part of the city past sprawling homes built on the hillside, he finally reached his destination. Turning into the drive, he practically bounced in his seat from eagerness as he made his way through the automatic wide iron gate up the stylized stone driveway. Just like in the movies, the driveway formed a loop around with a tidy two-car garage off to the side, and the main house nestled snugly against the driveway circle. In the center of the roundabout was a patch of well maintained emerald grass and a single small tree.

As he pulled in against the closed driveway door and got out of his car, he felt his heart leap into his throat. He was really doing this! And he’d be getting paid to do it! It was really sinking in as he slung his duffel over his shoulder and traipsed up to the front porch, ringing the doorbell on the stylish mid-century modern house and wearing a broad smile.

Moments later he was ushered into the house after confirming his identity. The missus seemed to be in quite an annoyed rush while the man of the house strolled casually over and shook Rush’s paw, giving a firm squeeze and a welcoming smile. Niceties were exchanged, and before he really knew what was happening the couple was pulling out of the driveway and zooming off in their luxury sedan, leaving Rush all alone in a strange new place.

He heard the bounding paws before he noticed the dog, gasping as an absolutely breathtaking huge mastiff bounded around one of the corners, barrelling straight into the surprised anthro and knocking him to the floor. His duffel landed underneath his head and cushioned him from the fall but the wind still got knocked out of him.

Brutus introduced himself in a flurry of licks and excited deep barks, which Rush didn’t try to stop. He felt shivers racing up his spine as the dog’s warm slobbery tongue dragged up and down over his face. He didn’t even stop it from dipping into his muzzle, spreading his lips just a bit wider as the dog explored every possible inch of his new playmate.

After long enough had passed, Rush decided he was going to see how far Brutus was willing to go, gently pushing on the massive black and white dog’s chest to nudge him side, getting on his paws and knees to unzip his duffel, shakily pulling out the bottle of lube he’d brought with him. Brutus excitedly nosed and pressed at the prone anthro’s hips, sides and shoulders before sneaking his tongue in to give more surreptitous kisses.

Rush reached back with timid hands and undid his shorts, pushing them down and sliding them off. He’d come prepared without his underwear, so as soon as the cargo shorts skidded away he was bared completely for Brutus. He didn’t immediately get a reaction, so he resorted to slapping and tapping at his ass, prompting Brutus to investigate.

Rush yelped at the sudden invasion of slobbery dog tongue, the jowls mashing into his inner cheeks as Brutus greedily licked into the dane’s tailhole, spreading it and depositing a healthy amount of his saliva inside. Rush’s yips turned to moans as he pressed his ass back and let the dog explore deeper, feeling the tongue curl and withdraw again and again. Finally, he seemed satisfied with his work and gave a huff of hot air into Rush’s distended hole, sending a shudder up his spine.

He expected to have to help Brutus in his next task, but he really didn’t. The dog leapt up as though driven by instinct and mounted Rush, causing his jaw to drop as he felt powerful muscular dog chest pressed firmly against his back, soon to be followed by jabbing thrusts in between his cheeks as the meaty red tip of Brutus’ dog dick sought its target.

Rush definitely had done his fair share of preparing, but mentally he had expected anything but this. He could tell by the heavy wet plap-plap-plap sounds behind him and the sensation of something smacking his own dangling nuts that Brutus was very much intact. A few more choice thrusts later and Brutus found his mark, drawing out an elated moan from Rush as he lost his grip on the lube bottle he’d been holding – so much for that...

Brutus was muscular and so his thrusts matched that powerful energy. Within seconds the dog was buried to the sheath inside of Rush, gyrating so hard that Rush had to struggle to maintain his balance. He felt the soft warm opening of Brutus’ sheath mashing against his puckering, quivering hole again and again as his body struggled to keep up with the primal breeding.

As was natural for dogs, they both had their tongues lolled out. Encapsulted in pure bliss, Rush’s moans got louder and louder. Brutus’ claws dug into Rush’s thighs and left a sharp sting that helped remind Rush he was being fucked by a feral dog – someone's pet. The more of Brutus he felt ram into his ass, the more he realized this dog was quite big – larger than even his largest toy. Hell, just the main length of Brutus’ cock was almost as big as the knot on his biggest toy. He wondered what that meant for the knot...

Rush’s eyes closed tight as he pressed back as best he could into the erratic canine thrusts. He could feel himself stretching to what he thought were his limits, but then something terrifyingly massive began ramming hard against his hole, struggling to gain purchase and slide inside. At this point, the copious amounts of precum and the dog’s own slobber had made a frothy mess of Rush’s backdoor, so everything was more than lubricated enough. Slam, slam, slam. Every body-rocking thrust brought Brutus closer to the point of no return.

And like that, without warning the dog forced his knot into Rush, making his eyes go wide with panic. He could feel his legs spread out further than they already were from the size of the knot, his pelvic bones struggling to accommodate such an impossibly large penetration. All he could do was stupidly drool and make weak grunting moans as Brutus introduced himself in the very best way possible, turning Rush’s wildest fantasy into a visceral reality...

Chapter 3: Side Effects

As hot dog cum flooded his bowels for the umpteenth time, Rush was in paradise. He could feel the strain in his hips as his pelvis struggled to contain the monstrosity lodged inside of him. It didn’t hurt – he'd done more than enough prep for it to feel good instead. His poor prostate was smushed to a pulp by the obscene intrusion, causing him to rocket his cum across the ground underneath his heaving chest as the two cemented their new bond.

He could feel the cum stream tapering off inside of him, but there was a new pressure deep in his belly. Something he hadn’t been prepared for. He was certain he’d cleaned himself out very thoroughly so it couldn’t be that. Not to mention the pressure was growing, ever so steadily. It was almost minute in how much it changed but he could definitely feel it getting bigger.

After about an hour stuck tied to Brutus, the mutt finally got tired and dislodged himself with an obscenely audible slurping pop sound, leaving Rush gaped for the gods as a thick rush of air whooshed into him, setting the ends of his nerves on fire as his hole began to mend itself, working to clamp shut once again. With Brutus’ weight off of him, he collapse onto his belly, wincing as he felt a slight bump there that hadn’t been there before...

Rush laid on the ground like that for a few hours collecting himself, during which time Brutus pranced around and he got more than a good look at the dog’s equipment along with flurries of kisses to his panting face. When he was finally able to roll over and pick himself up, he winced at his wobbling knees. He really had just taken the most brutal breeding of his life. If only he knew it wasn’t over yet.

He hobbled his way to the shower, still riding out the pleasure high of what had just happened, tossing his dirty clothes down and running the hot water to relax his aching muscles. Mostly it was his knees and calves, but his lower back ached a bit and there was this inescapable sensation of growing pressure in his belly.

After taking a much longer shower than he normally would, he stepped out and stretched, toweling off and stepping in front of the floor-length mirror placed in the corner. What he saw made his jaw drop. He had to turn to the side to be sure, but he definitely looked bloated. He brought his paw to his rounded out belly. It wasn’t severe, but it was more than it should be. He could barely see the faint outlines of his six-pack anymore as his belly had grown enough to begin to hide the muscles.

The rest of the evening passed by in a blur. He knew that he only had all of the next day to spend with Brutus, and he contemplated going for round two at some point. For now he focused on feeding the dog and making sure he had fresh water, taking him outside for an evening bathroom break. The boring things one had to do with their pets.

When he finally curled up into the guest bed for the night, he felt more exhausted than he’d ever been in his life, drifting off to sleep almost immediately. His dreams as always were filled with bouncing, plump dog dicks and fat throbbing knots pouring bucketloads of dog cum directly up his tailpipe. His favorite kind of dreams to have.

The early afternoon sun burned its way through his numb eyelids, causing him to wake and slowly squint his eyes open. As reality returned his senses to him, he became aware of a rather extreme pressure in his midsection. Struggling to sit up, he shielded his eyes from the sun streaming into the room, looking down at himself and going rigid with shock.

His belly had ballooned out overnight into what resembled a final trimester pregnancy. His belly button had even popped outwards, all trace of his athletic physique lost. As he climbed out of bed he looked at the clock on the nightstand, gasping when he realized he’d slept much longer than he’d planned to. He’d slept away the entire day and into the next. Brutus’ owners were due to return in a matter of an hour or two.

Not knowing how he was going to begin to explain himself, he struggled out of bed and rested a hand on his lower back to support the new weight of his immense belly. He felt a rush of pressure and could almost swear that something moved inside of him. Shaking off the thought, he waddled his way to the stairs and grunted, using the railing to support himself all the way downstairs. Brutus was waiting happily, tongue lolled out as he sprawled out on the living room rug, clearly just as contented as ever. A happy bark told Rush that Brutus had missed him!

As he reached the living room, he felt a twinge of discomfort followed by a much more visceral sensation of movement in his belly. He sank to his knees and cradled his belly with both hands, letting out a low groan. Suddenly, his anus dilated and he felt a deluge of warm fluid pouring down his inner cheeks and thighs, splattering wetly onto the carpet below. His eyes went wide as he stared between his legs at the clear fluids. Was that....did his water just break? How was this even possible?

He didn’t have long to think about it as another pressurized sensation swept over him and drew out a long moan, the anthro dane gently lowering himself onto his back and planting his heels onto the ground, spreading his legs wide. Oh yes, something was definitely moving inside of him, and whatever it was wanted out!

As the pressure moved lower from his belly into his anal cavity, he felt something press firmly against his prostate, sending his cock into rhythmic spasms of pleasure and drawing weak feminine moans from his lips as he cradled his belly and closed his eyes. He barely had to even push when he felt something beginning to emerge from his weakened tailhole, spreading the ring nearly as far as Brutus’ knot had done.

“Oh f-fuck...fuck me! Am I...giving birth???” Rush shouted out. He could feel sweat beading on his foread and trickling down his face as he fought another sharp wave of pleasure and pressure, the rest of whatever it was inside of him sliding out with a wet slurp, landing softly in a pool of clear fluids that reeked of dog cum.

Rush sat up just a bit on his elbows and his eyes went as wide as they possibly could when he indeed saw a beautiful black and white puppy beginning to writhe free between his legs, letting out its first adorable cries as it was given life. He really was pregnant. And from the looks of it, that wouldn’t be the only one coming out of him before it was over!

For the next few hours, Rush bounced between cumming violently and pushing pup after pup out of his sore, abused rear end. Brutus watched from the next room over, having moved when Rush entered and lost control of the pregnancy. There was a gleam in the dog’s eyes, and the way he refrained from investigating told Rush that perhaps this hadn’t been the first time he’d watched an anthro birth his pups.

The front door swung open just as Rush let out another pitiful series of moans and thrust his hips back and forth, feeling another pup slide free, his anus flexing and squeezing at the emptiness it left when it was birthed. A spluttering deluge of birthing fluid followed that pup, joining the group of five others that had crawled nearby, mewling and yapping cutely.

Brutus’ owners closed the door and Rush heard the soothing voice of the missus cooing down at him as they appraised the situation. “Oh, good boy. Brutus really liked you...this is more than we usually get in one sitting. Relax, and push them out for us...” Rush had no idea what he’d been expecting the reactions of the owners to be but it certainly wasn’t that. They’d just walked in on a very clearly male and very clearly aroused anthro giving anal birth to their pet dog’s young and their first reaction was praise and comfort...

Rush didn’t have long to dwell on it though. He felt the final cub beginning to emerge, but his anus had clamped down tight after the previous one, having squelched out the deluge of clear fluids. He gave a push and viscerally felt the pup sliding through his bowels and into his anal cavity, panting so heavily he thought he might hyperventilate as another orgasm wracked his body, his cock jumping and splattering his seed across the room, which was now thoroughly mess-ified from what was going on anyway.

Sure enough, his body relented in its constant sweeping contractions as the final pup emerged and joined the cluster of others, prompting the man of the house to clap his paws together and chuckle, eyeing Rush with pure happiness. Appreciation even. The missus had come back from the kitchen with a towel-lined basket and gently scooped the new pups into it, carrying them off upstairs and cooing gently at them all the way. That left the man and Rush alone as the dane struggled to come down from his biggest pleasure high he’d ever experienced.

“Well you did good sport. Just because you did so good we’ll double what we told you we’d pay. Thanks for taking care of our Brutus. We knew we picked right.” The man scratched at his chin and looked from Brutus to Rush. “Those were some gorgeous pups. Would you come back again for the same price next week?”

Rush’s mind was wheeling. He had to try and process everything that had just happened. Last he knew he’d been getting the fuck of his life from a dog he’d just met, knotted and swollen with cum. Then he woke up and had so little time to understand that he was pregnant before he gave birth to a full litter of pups. All of which led up to the couple returning and praising him, asking him back again...It was a no-brainer for Rush as the pleasure began to subside and a wicked grin crossed his face. He propped himself up weakly on his elbows and smirked up at the man, nodding. He’d be back...many times if he had any say in it. And so began the bond between Brutus and Rush, surely with many adventures yet to come...
