It was a day like any other in Nook's Corner, with the locals coming and going to the chiming of the doorbell, browsing the inventory of the cozy little store, buying carpets and wallpapers, chatting, laughing, socializing, but Tommy hardly noticed any of it. The little tanuki stood behind the counter, leaning forward and clutching the edge with trembling paws. He was feeling hot, shivering as if he had caught a fever, and he was so dizzy too, even though he had been perfectly fine fifteen minutes ago.

That's when Bob had come in to return a pair of dumbbells he had bought half a year ago for his New Year's resolution. The purple cat had tripped over the carpet in front of the counter and dropped everything, but it wasn’t the dents in the floor paneling that concerned Tommy. No, it was the sight of the feline's big, round butt that had burned itself deep into the nookling's mind when he had dropped on all fours to look for one of the dumbbells underneath a show table.

Obviously, it hadn’t been the first butt Tommy had ever seen. He only needed to look into the mirror to see one whenever he wanted, but this was different. He had never seen one like this before, pushed out, so round and full, so soft, squishy, and begging for a squeeze like a big stress ball. Not to mention the pair of smaller orbs that dangled down from it like plump cherries, jiggling and bouncing as the cat groped for his dumbbell. The little tanuki’s paws tightened even harder around the countertop and he groaned.

Why was he feeling like this? Why couldn't he stop thinking about Bob's big butt, even though the cat had already left? And why was there an odd bump on his dark blue waist apron, looking like a stem for the notched leaves that were the store's logo? At least the store was empty right now, as everyone had left for lunch, so nobody would catch him like this.

"Tommy, what's wrong? You're shivering." A deep, sonorous voice suddenly pierced Tommy’s thoughts, full of concern. "You look like you've caught a cold."

"A-ah!" The little tanuki squeaked and jumped up as his portly uncle Tom stepped beside him, and he hastily moved his stubby paws in front of his bulging waist apron. "N-no, it's nothing, Uncle Nook."

Tom raised a brow and looked at Timmy, who was stocking gift cards on the other side of the counter. "What happened, you two?"

The nookling's twin brother returned their mentor's gaze with a shrug. "I'm not sure. I wasn't looking when it happened, but I think it has something to do with Bob?"

"…with Bob. Yes," Tommy muttered and looked down with a blush, abashedly shuffling his feet.

"What did that lazy bum do this time? Did he try to pester you for a discount again?" Tom wondered, his paws on his hips.

"No, he fell and dropped his dumbbells," Timmy explained. "Then he got down on all fours and looked for them."

"…looked for them," Tommy whispered.

"And I'm not sure why, but Tommy started staring at his butt and just kept staring," Timmy continued his matter-of-fact retelling.

"…kept staring…" Tommy's blush deepened, and he tucked his striped tail between his legs, ducking away from his uncle. How often had they been told not to stare at other townsfolk? It was rude. Indecent. Naughty. Was that why he was feeling so funky now? "I'm sorry. I didn't mean to, Uncle Nook. It just happened, and I couldn't look away."

Tom took a step closer, but to Tommy's surprise, he didn't start chastising him. Instead, he nodded. "I see, yes yes. How are you feeling now, hm?"

"H-hot. Weird. And tingly? I'm not sure. Do you get sick from looking at other people's butts?" the timid tanuki whimpered.

A soft smile grew on his uncle's lips, and he shook his head. "No, don't worry, Tommy. You're not sick. This is just a sign that you're growing up, my boys," he chuckled.

"We're growing up?" Timmy asked.

"Growing up?" Tommy echoed.

"Yes, indeed. Come, let's head to my office. I will show you what I mean," the mature tanuki invited the twins with a wave of his paw. Then he stepped out from behind the counter and went for the door, flipping the OPEN sign to close the store for noon.

Tommy hesitated to move, still hovering both stubby paws over his bulging apron. However, when Timmy moved past him, he gathered enough courage to stumble after his brother into their uncle's office.

Half of the space in Tom’s office was taken up by his large, precious desk. Its dark wood was decorated with artfully carved floral patterns, and a large armchair with dark green upholstery stood behind it. The floor and walls were paneled with dark wood and decorated with landscape paintings of the village and its surroundings, the window was covered by blinds that only admitted a trickle of daylight, and the air was slightly stale, imbued with the smell of wood and the store owner's rich, familiar musk.

The flustered nookling stopped to take a shaky breath, still trembling as he wondered what Tom had in mind for him. He looked at Timmy. Timmy looked at him and shrugged.

Before any of them could say anything, their uncle entered with heavy footsteps. The wooden floorboard shook and creaked as the portly tanuki walked past his nephews and squeezed himself behind his desk. Without much ado, he gathered all sheets and documents into a big pile and dropped them into the closest empty file cabinet on the wall behind him. Then he swiped aside what was left and patted the edge of his desk. "Please, come closer. Take a seat, you two."

"You want us to sit on your desk, Uncle?" Timmy asked in surprise.

"On your desk?" Tommy whispered.

"Yes, right here," Tom Nook replied, giving them another encouraging wave.

Timmy was the first of the nooklings to get moving. He only paused when he reached the desk, shooting their uncle a wary look as they usually weren't even allowed to touch his most precious table. But when the mature tanuki nodded, he turned around and climbed onto the massive wood slab.

Tommy hesitated a little longer, but eventually followed his brother's example. Taking his paw, he climbed up and sat right next to him, shivering slightly as the cold, varnished wood touched his butt and big, plump nuki balls.

"So, what do you want to show us, Uncle Nook?" Timmy wondered, kicking his legs back and forth as he curiously looked at their mentor.

"…show us, Uncle?" Tommy echoed the sentiment, his thighs clenched together.

"Please, take off your aprons, you two. You don't need them in here," Tom requested as he slumped onto his armchair with a comforting smile.

"Sure!" Timmy chirped and untied the knot that held his waist apron, baring his chubby thighs and his big, drooping hazelnut ballsack without a moment's hesitation.

Tommy wasn't nearly as keen to strip his apron as his brother, tugging the blue fabric in between his legs. "I-I don't know, Uncle Nook. Are you sure it's okay if I do it?"

"Yes yes, it's all good, Tommy. I'm not upset with you. No, I'm actually quite happy," Tom chuckled. "And don’t worry. It's just the three of us here."

Biting his lip, Tommy tugged at the knot of his apron with quaking fingers, loosening the string until the fabric unraveled on its own and followed the call of gravity. As it fell down, it brushed against whatever caused his bulge and stirred a strange, sudden tingling. Gasping softly, he looked down and his eyes grew wide as plates as he spotted his engorged penis. "O-oh, what's wrong with my pee pee, Uncle Nook?"

The young tanuki glanced at his twin to see if his pecker had changed too, but Timmy's member looked the same as ever. Wrinkly, soft, and flaccid like a little chocolate elephant's trunk, so tiny as it lay atop the male's big, plump sack. Meanwhile, his own was like a fat, swollen sausage with no more folds and wrinkles, standing straight up with a hint of pink glittering at the tip, and most disconcertingly, it was pulsating.

"Why is it so big?" Timmy asked, pointing at his brother's cock.

"…so big?" Tommy whimpered, clutching his thighs as he tried not to panic.

"Don't worry, Tommy. That's a perfectly natural thing to happen when a boy gets old enough, and it looks like you're both old enough now, yes yes," Tom explained with a comforting hum. "It's called an erection or boner when your pecker gets big and hard like that."

"But why does it happen? Why does Tommy have one and I don't?" Timmy wondered with a hint of indignation. A twitch went through his soft shaft as he kept staring at his twin.

"You said it happened after you looked at Bob's butt, hm?" Tom asked.

Staring at the armrest beside his uncle, Tommy nodded coyly. "Uh-huh."

"Well, there you go. Sometimes, if you see someone you really like or something that gets you all hot and fuzzy inside, your pecker gets hard. No use in fighting it because it's just part of who we are, yes yes," the mature tanuki chuckled. "Other times, it even happens for no reason. Or when you're really relaxed, especially in the morning after a long, good sleep." He rose from his armchair with a smirk, only to drop to his knees in front of Timmy. "While it is tricky to hold back an erection, getting one is as easy as winking. You just need to give it a little attention~"

The nooklings peered at their uncle in open-muzzled awe as he slipped his big, round head between Timmy's legs and reached for his small, limp cock. He grabbed it as tenderly as a delicate flower, squeezing it a little and tugging on it to slowly peel back his nephew's long, loose foreskin. With a smack, it revealed a soft, round pink tip underneath, and as he kept baring more until its rim became visible. Hovering his long nose above it, he took a deep sniff.

"A-ah, Uncle Nook, what are you doing? This feels funny," Timmy gasped, gripping the edge of the desk as he was hit by an unfamiliar sensation. "It tingles."

"…it tingles," Tommy whispered. He wasn't even getting touched, but just watching the other tanuki made his insides tingle and his heart pound. He couldn't look away, and he wasn’t sure why he was so electrified by it.

"Good. Sit back and watch, Timmy," Tom purred and kissed the nookling's round, soft tip. "What I just pulled back is your foreskin. It's what protects your glans, because it's quite sensitive, yes yes." Then he darted out his tongue and brushed it against his nephew's tip, licking across his peehole and around with a warm huff.

"That's my peehole. That's dirty, Uncle. That's where my pee comes out," Timmy gasped, but he didn't stop him. His eyes were wide in awe, and his whole body trembled as he watched his member swelling in Tom's grip, thickening and stiffening with gentle throbs. "I-it's getting bigger."

"…bigger." Tommy was sitting on the very edge of the desk, his own erection pulsing and stiffer than ever, but completely forgotten as he was enthralled by the exciting view.

"Don't worry, it's fine, Timmy. I actually like how it smells and tastes. So thick, so salty, so musky," the mature tanuki sighed, smacking his lips as if he was savoring an expensive wine. "It's delicious, yes yes. And you see how you are getting an erection now, hm?"

"Y-yes. Oh wow. It's so tingly and warm and stiff. So twitchy," Timmy squeaked.

"…so twitchy," Tommy echoed, his own pecker throbbing and oozing pre.

"Indeed, and it's still growing. You boys have really big peckers. That's what, five inches, hm?" Tom held his other paw next to Timmy's turgid schlong to measure it. "You're bigger than most other grown-ups, and you're going to get even bigger when you grow up."

"Oooh, my pee pee is going to be even bigger?" the nookling gasped.

"Yes, so big and delicious," their uncle purred before he swirled his tongue around the rim of Timmy's glans. Then he wrapped his lips around it and slowly glided it into his muzzle, taking inch by inch until his lips pressed against his furred crotch.

"A-ah? Aaah?! Ooooaaaahh!" Timmy burst into a wet, high-pitched cry as Tom swallowed his whole pecker to the base, clenching his paws and feet in overwhelmed delight. Even after the older tanuki pulled away again with a naughty slurp, he was left shaking and speechless for another moment. He hiccuped. Then he stumbled out, "What was that? That felt so… so… warm. Wet. Tight. Good. How did you do that, Uncle Nook?"

"With lots of practice, Timmy~" Tom chuckled and pressed his lips against his nephew's glans with a fat smack. Then he pulled away, a strand of glittering saliva dangling between his muzzle and the nookling's throbbing, spit-soaked penis as he turned toward Tommy.

Tommy sat up and licked a strand of drool from his lips. A powerful shiver raced through him as he was at the center of his uncle's attention once again. "It's even bigger now. And leaky? Sorry," he apologized meekly.

"Don’t be sorry, Tommy. That's completely normal when you're getting aroused," the portly tanuki purred and wrapped his hand around the timid boy's shaft. Steadying it with a gentle squeeze, he kissed his tip and lapped up the spilling pre with a wet slurp.

"We're getting aroused?" Timmy asked, his wetted cock trembling in the cool air and starting to drool like his brother's shaft.

"…a-aroused?" Tommy whispered, mewling in confused pleasure as his uncle's ministrations flushed him with fresh hot tingles.

"That's what you're feeling like right now, all hot and tingly. Sensitive and excited, curious and probably eager to look at naked bodies, yes yes," Tom chuckled.

"But why? Why do we get boners? Why do we get aroused, Uncle? Why do our bodies do that?" Timmy inquired.

"Why?" Tommy muttered, biting his lip.

"When a girl and a boy really like each other and want to have children with each other, they get together naked. The boy gets hard like you right now and puts his penis into the girl's vagina. That's what grown-ups call sex," Tom explained, demonstratively tightening his paw around Tommy's cock and stroking it to draw out another stunned squeak and squirt of pre from the young tanuki. "The boy thrusts it in and out until he feels like he's about to explode."

The nooklings gasped in unison.

"But it's a good kind of explosion. It's fun and pleasant, like an extra reward for having sex, yes yes. And that's where your balls come in."

"Our balls?" Timmy reflexively reached for one of his plump, saggy orbs.

"…balls?" Tommy looked down at his own ballsack, draped over the edge of the desk and hanging down.

"Yes, your beautiful, big, wrinkly balls, yes yes," their uncle swooned, dragging his tongue from Tommy's tip to his sack, swishing it along the raphe before he shoved his entire snout into the loose fold between his swollen testicles.

Tommy groaned as the mature nuki huffed and licked his nuts with hungry sniffs and slurps. Then, his uncle plastered his thick, wrinkled skin with kisses all over, not missing a single inch before he pulled away with a satisfied grunt.

"These gorgeous fellas produce something that's called sperm. Trillions of little droplets that can swim like fish, and when a boy has an orgasm and cums, they all come out from your peehole in big spurts." He drew his finger from Tommy's balls up to his tip, tapping his leaky urethra. "If they end up inside a girl's vagina, they swim deep inside her, and if she's fertile, there are tiny eggs inside her that wait for the sperm to cum and hug them. Once that happens, they grow into a baby inside her. That's what all of this is essentially for: making babies, and with balls as big and gorgeous as yours, it's like you boys are made for that. In fact, they're going to get even bigger when you grow up, yes yes."

Tommy's mind was too clouded with arousal to follow all of his uncle's explanations. Especially when he talked about tiny eggs and droplets, the boy lost track, but he clearly felt Tom's enthusiasm as he talked about it. The twinkle in the mature tanuki's eyes was almost as exhilarating as his warm, soft paws around his cock and sack, and he wondered what it would be like to have an orgasm. Not that he expected to find out, as there was no girl in sight.

"What? Our balls are going to get even bigger? But they're already so big and heavy," Timmy gasped, still groping his massive orbs with slight concern.

"Oh, don't worry, it's fine. I would know, yes yes," Tom chuckled and let go of Tommy's bits. As he got up on his feet, the twins immediately spotted a suspicious bulge on his waist apron, and when the chubby store owner untied it, he revealed that he was having a boner as well. Only slightly longer than their peckers, it was all the thicker for it, interspersed with pulsing, meandering veins and glistening with sweat. However, it was his massive nutsack that caught their attention like honey. Like their own, it dangled down below the male's knees, comprising two huge balls inside an excess of thick, wrinkly skin that filled out the entire space between his fat, soft legs. "As big as this, and maybe even bigger~"

It wasn't the first time Tommy had seen his uncle's huge, drooping balls. The lowest part of them peeked out from underneath his apron at all times anyway, but the situation changed completely how he thought about them. Looking at Bob's butt and then talking about boners and sex had rewired his perception of Tom's now irresistibly intriguing nuts, and he was unable to look away from them. A strand of drool dripped from his open muzzle, and his paws clenched the same as with Bob's plump, soft backside as he was overcome not just by a fresh rush of tingling arousal, but the maddening urge to touch, to squeeze, to hug those massive orbs.

"Do you want to touch them, hm?" Tom asked with a smirk as if he had read his nephew's mind. Strutting around the desk, he teased them with a perfect view of his swinging, bouncing schlong and jigging, swaying balls, flaunting the sheer weight of his fat assets. Then he bent over to open a cabinet on the floor, flicking up his big, striped tanuki tail to flash his huge, plump ass at them, the puffy pink hole in between, and his bloated sack hanging low.

Tommy let out a shaky, high-pitched moan as he was reminded of Bob's backside in the store earlier. The tingles grew almost painfully intense, and the blazing heat inside him made him sweat and pant. Too excited to sit tight any longer, he slipped off his uncle's desk, leaving behind a shiny, sweaty imprint of his soft, tubby backside on the varnished surface as he stumbled toward Tom.

"Oh, it looks like someone can’t wait to get a closer look?" the mature tanuki laughed as he turned around and spotted his usually so timid nephew. “Don't worry, it's fine, Tommy.” He had grabbed a large terrycloth beach towel from the cabinet and draped it across the wood-paneled floor. Then he dropped onto it and lounged himself across his back, his feet pulled up against his butt and his sweaty, wrinkly balls spilled across the soft fabric. Folding his paws behind his head, he winked at his nephew and purred, "Please, come closer and have a look. Cop a feel. Take a lick. Explore me however you want~"

Pressing his fists against his pudgy chest, the nookling shot his uncle a hesitant look. This felt too good to be true. Was this a test? Was he dreaming? He cautiously glanced back at his twin brother, only to find him sitting on the other edge of the desk, leaning forward as he ogled their uncle with big, hungry eyes and drool dripping from his chin.

Finally, Tommy stepped forward, only to trip over the edge of the beach towel. With a squeak, he tumbled right onto his uncle, but Tom caught him with his feet and slowly set him down on top of his giant, gorgeous balls.

"Careful, Tommy!" the mature tanuki chuckled. "No need to rush. Take all the time you need~"

"Sorry, Uncle," Tommy whispered, his heart racing a mile a minute as he slowly wrapped his head and quite literally his stubby arms around the older male's testicles. They were even larger up close, each of them bigger than his own head, and below the loose, wrinkled skin, they were firmer to his touch than he had expected. "Oooooh."

"What is it? Do you like it, hm?" Tom purred, his half-lidded eyes resting on his nephew as the young male gingerly explored his orbs.

"Yes! They're so big. And so heavy. And so hot," Tommy sighed as he glided his chubby paws across the foldy skin. His uncle’s sack wasn't just warm to the touch, but veiled in a layer of sweat and the male’s thick, familiar musk. His slender snout twitched as he breathed in the exhilarating aroma, and he let out a soft mewl as the rich, potent concoction made his head spin and fanned the blazing fire inside him. Drooling and dripping from his tip, he pressed his nose into the cleavage between Tom's massive balls and took another deep, heavy breath. "This smells… so good. It's making everything tingle even more."

"Wonderful. Go ahead, sniff them, Tommy. Lick them. Kiss them. Whatever you want, yes yes," the mature tanuki encouraged his nephew.

Tom didn't have to tell the eager nookling twice as he parted his lips and flicked his tongue against his sweaty sack, filling his muzzle with its salty taste. Tommy shivered, groaned, too dizzy to think for a moment. Then he went in for seconds, treating his uncle's balls to another, deeper lick, slurping along the natural folds and drooling all over as they were more delicious to the horny cub than an entire bowl of his favorite ice cream.

Tommy would've probably continued savoring and spit-washing the other male's big, sweaty nuts for the rest of the day, but Uncle Nook grabbed and waved his thick, pulsing cock and diverted his growing curiosity to his fat manhood. "Do you maybe want to give this a closer look too, hm, Tommy?"

"OooOoh, yes, Uncle!" the little tanuki squeaked and climbed further onto the other male's bloated balls. Hugging them with his whole body, he only paused briefly with a hot gasp when his achingly erect, twitching pecker slipped against the wrinkly, sweaty crease between the orbs, showering him with a fresh, prickling rush of stimulation. Then he reverently wrapped his paws around Tom's big, throbbing penis. It was stiff and hot, pulsating against his pawpads, yet soft and squeezable. "A-and you put this inside a girl?"

"Yes, or a boy," Tom replied with a wink.

"A boy?" Tommy gasped, reflexively bucking his hips as his glans bumped against his uncle's sack.

"Why would you do it with a boy?" Timmy wondered from the desk.

"Because it's not just about making babies. It's also a lot of fun on its own with someone you really like, yes yes," the portly tanuki chuckled, tenderly stroking Tommy's head as he thrust against his ball cleavage with a shaky moan. "Isn't it, Tommy?"

"Ah, yes. This feels so nice. So soft and warm and nice, Uncle Nook," the nookling whimpered, his big blue eyes rolling up as every stroke against his uncle's hot, sweaty sack showered his receptive mind with even more stimulation. He tightened his hug around Tom's and pressed his lips against the side of his schlong, drooling over it, huffing it, lapping at it, taking in more of that exhilarating musk and salty, sweaty aroma. "It's weird. Your peepee tastes so good. Is that why you licked ours?"

"Yes, they're delicious. And it feels really nice for me too, Tommy. Don't stop," Tom groaned, a lustful tremble in his voice as he reached for the edge of his foreskin and pulled it up two inches before his nephew's eyes.

Both nooklings watched in amazement. Then, Tommy moved his muzzle a little further up and started licking the loose fold and the thick, throbbing glans underneath. Before he knew it, he even tucked his taster into the hot, soaked gap in between tip and foreskin, delving it deep inside to slurp up his uncle's tasty, salty flavor, and he eagerly gulped down the sticky clear goo that oozed from his urethra while his hips moved faster and faster as if they had developed a mind of their own. "Why is your pee so tasty, Uncle Nook?" he whimpered, finding himself unable to pull away or stop at something that should've grossed him out.

"Because that's no pee, Tommy. That's precum. It's sticky and salty and slippery to make sure that a penis slides more easily inside a girl or boy," the mature nuki explained.

"But boys have no vagina. How do you put it inside a boy?" Timmy interjected, his head tilted in confusion.

"…inside a boy?" Tommy echoed his twin.

With a big smirk, Tom raised his legs and grabbed his ankles, bending his legs as far over his body as his big, round belly would allow.

Tommy wasn’t prepared for his uncle's sudden movement and tumbled back over, plopping onto his butt with a surprised squeak. However, any budding complaint melted into an open-muzzled gasp when he laid eyes on the chubby male's fully exposed backside. Two big, fat buttocks embraced his tight pink pucker like the cheeks of a peach, and the little nuki was too mesmerized by the view to say a single thing.

"Every boy has a nice, tight hole down here, which is perfect for practicing breeding with girls and having lots of fun," Tom cooed, swishing aside his big, striped tail and spreading his snug, clenching anus with his paws.

"A-are you sure?" Timmy asked hesitantly.

"…sure?" Tommy gasped, less reluctantly, as something about that juicy, winking hole made him drool even harder.

"Yes, I'm very sure. It even has something inside that's called a prostate, which feels amazing if you rub it with your pecker. So why don't you go ahead and put your pee pee inside my butthole, Tommy?" Tom suggested with an encouraging smile. "I promise it'll feel even more amazing for you. Come on, try it."

Tommy hesitated for one more heartbeat, but his uncle's words and promise convinced him. Rubbing his cock against his balls had already felt great, so he couldn't even imagine what it felt like for something to rub his cock all around. He got up on his knees and hastily shuffled toward the other tanuki, moving close enough that his twitching tip almost touched his fat pink ring.

"Grab your pecker and press it against my butthole," Tom instructed his nephew with a visible shiver of excitement. He let out a deep groan when Tommy's glans kissed his ring with a pre-soaked smooch. "And now you very carefully and gently push it in. Don't go too fast, so I have time to get used to it."

Tommy nodded quickly, trembling even harder than his uncle when he exhaled, and his asshole opened up with a wet smack. Then he gingerly thrust forward, parting the puffy pink ring and sinking his tip inside, his foreskin peeling back to expose the most sensitive bits. He honestly wasn't sure what to expect, only hazily remembering the sensation of his uncle’s lips around his pecker, so he was completely blown away when he was hit by a massive surge of sensations. "Aaaahhh, it's so warm! And so tight! And so… ooooOOooohhh…"

Words failed the nookling. His paws clenched up, his fingers trembled, and his whole body locked up as his uncle's channel wrapped itself tightly around his sensitive penis. The hot, clenching hug overwhelmed him so much that his mind blanked, and it also stirred an odd, new pressure inside him, exacerbating his arousal and fanning his lust into a hot, sparkling rush.

"Ah, wow, you're really big for your age, Tommy," Tom groaned, his voice quaking with pleasure much greater than for his favorite honey or bells.

"O-Oh, that's not bad, right?" Tommy gasped.

"No, not at all. I love it, yes yes!" the portly tanuki laughed. "It's perfect, Tommy. Now grab my legs with your paws and give me the rest of your big, perfect pecker."

Tommy's eyes widened and his cheeks flushed with excitement. He hurriedly wrapped his stubby paws around Tom's thick, plush thighs and pushed his hips forward, sinking the rest of his sensitive erection into that tight, clenching tunnel.

The little nookling moaned out with shaky pleasure as he was overwhelmed by even more stimulation, and he paused again once he was balls-deep inside his uncle, his heavy sack draped across the other male's plump backside.

"And now keep going. Pull back, thrust forward, just like you did with my balls, Tommy. In and out," Tom told his nephew.

"O-okay, Uncle Nook," Tommy whimpered. Not that he needed much instruction, as his natural instincts kicked in and pulled him backward. He groaned as his uncle's tight, hot insides rubbed against his sensitive pecker again, and again. He swiftly realized that the more he thrust, the faster he thrust, and the deeper he thrust, the more he received of that exhilarating, addicting stimulation, and he quickly picked up his speed, barely able to control his surging lust as he had never experienced anything like this in his young life. "Ooooh, this feels so good, Uncle! I love this! I love your butthole! It's amazing! Breeding is amazing!"

"Yes, you're doing great, Tommy. Keep it up," Tom replied, his voice growing heavier and throatier with every thrust.

His uncle's pleasure riled Tommy up even more. Never before had he heard or seen Tom in such a state, which opened up a whole new world of fun to the boy. Tightening his grip, he bent over the bigger male and thrust even faster, moaning, mewling, gasping for air, and sucking in Tom's sweaty, intoxicating musk while trying not to choke on his spit. "Yes! So good! I love you, Uncle!"

"I love you too, Tommy," the mature tanuki replied and winked at the other nookling, who was sitting on the edge of the desk, spellbound by the spectacle. "I love you both, my wonderful boys~"

Tom's words were disrupted by wet, meaty slaps as Tommy was now pounding him fast enough that his heavy, drooping sack started to swing and flail like a pair of wrecking balls. Again and again, they battered against his uncle's fat butt, making it jiggle and ripple with the promise of the boy’s first big, gooey load of his life.

At the same time, the little tanuki bent forward so far that he almost buried his face back against Tom's huge, heavy balls, and the sight and smell of these wrinkly, sweaty breeding orbs and fat, throbbing schlong sucked him in like the promise of a whole tub of ice cream. With a hungry moan, he opened wide and shoved his tapered snout into the gap between the balls and the base of his cock, sniffing, huffing, kissing, and slurping it, gorging himself with needy greed. His paws didn't remain on his uncle's thighs either, but slipped down onto his sack to squeeze and knead them all over, exploring and savoring every inch and fold, every ounce of his impressive virility while his own balls started churning with a wet, audible gurgle.

Drowning in stimulation, overwhelmed and completely taken up by his uncle's tight hole and delicious aroma, the pressure inside the young male surged to a point where it enveloped his whole mind. "Oh, this is so good, but so weird," he whined, struggling to grasp the unfamiliar sensation. Only one thing came close to it. "It feels… like I'm… going to p-pee."

Tommy tried to slow down and pull out before it got too much, but his body refused to comply. The urge for more was uncontrollable, and the mere thought of stopping made him thrust even more desperately. "U-uncle Nook, it's so good, I can't stop! I'm going to pee!"

"It's fine, Tommy. You're not going to pee; what you're feeling is your first orgasm, yes yes," Tom reassured the distraught boy. "Don't fight it. Don't hold it back. Cum inside your uncle. Let it all out!"

His encouragement dissipated the timid nookling's hesitations, and before long, the stimulation and pressure grew so intense that Tommy couldn't hold them back for much longer. "Uncle Nook, it's coming! I'm peeing! Ooooh!" he cried out.

Tommy's cry melted into incomprehensible bliss when he succumbed to his first-ever climax. It was like a dam bursting inside him, flooding him with pure, perfect bliss instead of water as it swept away all his thoughts and worries. With it came a heavenly rush of relief that went beyond the most satisfying piss with the fullest, most aching bladder, and he stopped thrusting altogether, collapsing onto his uncle's soft, warm body and hugging his massive balls against his tubby chest as he unraveled into the greatest joy of his young life.

The nookling's heavenly bliss was paired with an intense bodily reaction as the muscles in his entire abdomen began to flex in a frantic rhythm. His heavy, swollen testicles jumped, the loose, wrinkly skin of his sack rippling and jiggling as they clenched and tightened inside, and buried inside his uncle's butt, his penis twitched and tensed just as vigorously. For the first time ever, his urethra stretched and widened to accommodate his incredibly thick, gooey seed, and his peehole opened up to shoot a fat, stringy rope deep inside Tom's guts.

"It's coming out! Peeing! So much! So hot! It's coming out!" Tommy whined in a lust-drunk mantra between sloppy licks and kisses, his drool washing all over his partner's crotch, soaking his skin and fur. However, it was nothing compared to the flood that burst from his tip, as a violent volley of squirts and spurts erupted from his cock like from an open fire hose. "Peeing… so much…"

"Yes, let it all out! Give it to me! Cum inside me, Tommy!" Tom groaned with guttural delight, clenching his toes as he savored the stuffing.

Unfortunately, their intimate union wouldn't last as the mind-shattering climax overwhelmed Tommy so much that his paws loosened and he failed to maintain his balance. Slowly slipping to one side at first, it wasn’t long until he lost grip altogether and fell onto his side, yanking his spurting, twitching pecker out of his uncle with a helpless squeak.

However, it hardly mattered that the young tanuki's cock had slipped out of its tight, warm embrace, as he kept cumming in a blissed-out stupor regardless. Clutching the towel beneath him, his face remained scrunched up with joy and his eyes stayed rolled back while his penis whipped up and down with every violent spurt, blasting rope after rope of his thick, milky white seed far across his uncle's office, already brimming with trillions of swimmers and far beyond the blanks a normal 8-years-old would shoot.

"Yes! So good! Best thing… ever!" Tommy warbled in his trance, oblivious to the mess he was making of himself and the wooden floor around. Not to mention that a lot of it splattered Tom's thick thighs and bared plump backside, glazing his loose, cream-stuffed butthole with an extra layer from the outside.

Meanwhile, Timmy watched his twin brother's eruption with heated interest and beads of sweat darkening his fur as if he was sitting in a furnace. Biting his lip, he clutched the edge of the desk so hard that it almost hurt, while his pecker was pulsing and leaking pre like a broken faucet. No drops, but a steady stream of sticky, clear goo washed down his strikingly thick pre-adolecent girth, soaking his inner thighs and balls, dripping down on the floor to form a small puddle beneath his feet.

"Aaah, I'm so hot, Uncle Nook, and my pee pee is so hard it hurts," the tanuki boy whimpered, panting and sweating as if he had run a marathon. "What do I do?"

"Don't worry, I can help you with that, Timmy," Tom purred and rolled onto his side, pulling his upper leg against his soft, cushy belly. With a wink, he patted his lower thigh and beckoned Timmy with a wave. "How about you come here and put your pecker inside me too, hm? After all, it would be mean of me if I only let Tommy practice breeding with me. Just…"

The portly tanuki wasn't even done talking when Timmy jumped off the desk and stumbled toward him, desperate to take care of his aching arousal. Especially seeing his brother's continued, open-muzzled delight fired the boy up like nothing else, and he dropped onto his uncle's lower leg without hesitation.

"Oooh, this feels so good," the pent-up tanuki groaned when his sweaty cock slapped against his uncle's thigh. The mere touch was enough to make it twitch furiously, squirting a rope of pre all over Tom's nuts with the same force as Tommy's still ongoing, seemingly bottomless eruption.

"And it's going to feel even better once you've put it inside, yes yes," Tom promised, spreading his soft cheeks for his nephew.

As Timmy was overwhelmed by horny anticipation, the primal breeding instincts tucked away deep inside him finally woke up completely. He shifted forward and grabbed his uncle's raised leg with both paws, hugging his thick, furred thigh against his chest as he glided his sensitive pecker against the bigger male's loose asshole. The fact that it was soaked and dripping with his sibling's seed barely bothered the needy boy. On the contrary, Tommy's thorough pounding and slippery baby batter made it all the easier for him to slip his tip into his uncle's hole and then ram in the rest with a high-pitched whine.

"O-oh fuck, you're just as big as your brother," Tom grunted as he was spread once more by five glorious inches of preteen cock meat, and Timmy left him no time to get used to the second stuffing.

"Oooh, you're so warm and tight, Uncle. This is… this is so good!" Timmy babbled, drooling against his partner's thigh as he took to the leg-glider position as a fish to the water. In and out, in and out, his hips moved in a rapid blur, fueled by the uncontrollable desire to relieve that hot, sweaty tension inside him, but first, it grew even more intense as the first signs of a rapidly building first orgasm built inside him.

"Yes, you're doing great, Timmy. Don't hold back. Go as hard… hhhnnnff… as you want," Tom encouraged his nephew with a throaty groan, his whole body shaking from the boy's frantic rutting.

It wasn't only his uncle's words that spurred Timmy on further, but also his smell. Like his twin, he was immediately hooked on Tom's thick, intoxicating musk, and he pressed his nose tightly against his furred thigh to breathe in more of it with deep huffs and moans. Soon, he was going hard enough that his ballsack was swinging up and down wildly, making his uncle's lower thigh ripple and jiggle with resounding claps, all the while he was hit by stray spurts of cum from his brother.

Still on his side, still cumming, Tommy had wrapped his stubby, sweaty paw around his spurting pecker. First, he had only grabbed it to hold it steady, but the extra tickle of stimulation from the touch naturally spiraled into more. He squeezed it, stroked it, and now pumped it with breathy mewls, drawing out fresh globs of gooey sperm. Not really looking where he was aiming, he ended up shooting most of it directly at Tom and his brother, showering them with rope after rope while his sibling was in a heated rush to dump his own first load deep inside their uncle.

Not that Timmy's rush was going to last particularly long. Already primed from watching Tommy's eager pounding, the tanuki boy lasted for about a minute of relentless, mindless thrusting before the pressure inside him spilled over. "Ah, Uncle Nook! It's happening! I'm gonna pee too! I'm gonna…"

Timmy's head tilted back, his tongue lolling from his muzzle as he burst with a resounding cry of bliss. It was as if he had been struck by roaring thunder and blinding lightning all at once, his mind shattered by an incomprehensible surge of pleasure while his body kept on moving, his thrusts even fiercer, needier, yet unsteady and jerky.

"Yes, don't hold back! Cum for me, Timmy! Let it all out~" Tom roared with joy, wrapping his bushy striped tail around his nephew to hold him close as he bust his nut.

Timmy managed a few more shaky thrusts. Then he slumped against his uncle's thigh, panting, heaving, moaning, and whining in overwhelmed bliss as his nuts initiated their breeding dance. Jumping, clenching, churning their thick, sloshing contents, they forced his load through his prostate and up his flexing pecker, out of his widening peehole and deep into his uncle's guts to mix with Tommy's previous eruption.

"Oooowwwaaah, this is the best. Thing. Ever!" the young tanuki squealed, pushing his spurting cock as deep into Tom as he could. "So much! So warm! So hot! So good! So tingly! So much! So good!"

Timmy unloaded a whole ounce of his creamy, gooey boy batter inside his uncle before the bigger male loosened his tail's embrace around him. No longer steadied by Tom, it didn’t even take a heartbeat before his shaky paws lost their grip on his uncle's sweaty thigh, and he followed his twin brother's fate, slipping off while he was too busy cumming his brains out to stop it.

However, the boy didn't drop onto the towel, but he fell right on top of his brother. Both of them yelped in surprise, only to reflexively catch each other with their arms in a spontaneous hug, and while Tommy moved his paw away from his cock and Timmy no longer enjoyed the tight, squeezing embrace of his uncle's ass, they quickly found a perfect substitute. Face to face with their soft bellies and bodies squished together, their cocks ended up pressed tightly against each other.

At first, Timmy was too stunned to move, but with his brother's hot, swollen pecker throbbing against his own, it was only a matter of moments before he yielded to the instinctive urge to thrust. Slowly, he glided his sensitive, spurting penis against Tommy's member, only for his twin to join in with shaky hip thrusts, and with mutual moans, they tightened their hug and thrust faster.

"Oooh, Tommy, this is so good," Timmy groaned, sharing his passion with the one person who understood him better than anyone else.

"…so good," Tommy warbled, pushing his snout deep into the crook of his brother's neck as he lost himself in his resurging climax. All the while, he spilled spurt after spurt of his cum over Timmy's chest and belly while the other boy did the same with him, wet, naughty squelches filling the office as they smeared and rubbed their lewd scent over each other and into their fur and skin.

"I love this. This is amazing. Thank you for showing us, Uncle Nook!"

"Thank you, Uncle Nook!"

"You're more than welcome, boys," Tom chuckled, a beaming smile on his lips as he sluggishly pulled himself up from the towel. He took a quick look around to assess the mess they had made. Then he gave Timmy a pat on the back and headed for his desk to pick up his waist apron. "And you're a lot more productive than I expected. Plenty to clean up, yes yes, but that's on me. I'm proud of you two~"

The round, fuzzy ears of the twins twitched at the praise, but they didn't respond. They were still too enraptured with each other, frotting, moaning, and hugging in a rapturous trance as their first ever orgasm washed through their minds like one. Already two peas of a pod, it bound the twins even more inseparably together, yet their endeavor into a whole new world of lewd fun and sex had only just begun.
