The males of the Lambert family had always been known for their extreme hairiness and manliness. For being a stereotyped species known for their submission, foxes, one wouldn't think they'd be so manly. 

But yet, their recent bloodline had borne the most manliest males of them all: Simon. His body is covered in jet black hair that seeped that distinct earthy smell so much; that you could smell it coming from him even if he was several rooms away for you. 
When he was younger, he tried to shave off the body hair that just miraculously grew out of thin air when he was 12/13, but to no avail. Within just a couple of days, it grew back to full length. 
That's not to mention that his voice broke when he was the same age as soon as his body hair started growing, and many teachers and friends thought of it as an early puberty. That is, until they knew he was from the famous Lambert family - purely known to house the manliest men in the whole world. 

After some time, he learned to embrace it. If he can barely get into a shirt because of the thickness of his body hair, so what? 
If somebody complains about his smell after when he sprays as much deodorant as he can on himself, so what? He learned that there was no point trying to hide something in plain sight. 
Besides, as he grew older, his sexual experiences widened. Simon started to bed with less women, as they always complained about the smell, the excess of body hair, or maybe both. 
But the gay men? They were different. They loved his masculinity! 
Simon would find himself to be appreciating men more, as they appreciated him in turn. In fact, he could never get the gay men off him. When he was at the gym, every man turned to look at that luscious hairy body, where barely a smidge of his orange fur could be found under that huge blanket of wiry, yet wavy body hair. 

Knowing how much men loved him, he began to experiment with the same sex more, until… He began to like them more than women. Men just love his body more than women, who always seem to complain about it. 
This incurred some complications within his current relationship with his wife: for one, sex was no longer enjoyable. And two, they began to grate on each other's nerves more and more - until they had enough, eventually divorcing. 
Having a son that's now 12 years old (quite near that age where the “special puberty” happens), he took him under his wing so he could support him as much as possible in this strenuous time of his life. He doesn't want his son to feel lonely like he did when it happened, so he was monitoring slight changes carefully. But looking for slight changes was futile, as the puberty always happened in one go. Still, he would try his best. A part of him was always looking forward to this moment, infact, he was quite horny thinking about it. 

His son looked quite cute: orange auburn fur, sky blue eyes; he had all the makings of his father… Before his puberty. 
When his son grows up tonight, Simon is quite curious on how he'll change. 

Before having learned to love himself and his extremely manly body, Simon acquired a kink for musk and manliness too. 
Seeing his son go through the transition between boy to a full on manly male worthy of his family's name… It made him sigh in anticipation and huge cock quiver for attention underneath those tented pajama bottoms. 

His son, Andrew, is stirring in his sleep. Simon sat on the chair in his room, carefully watching through his sleep-deprived state.
“It's going to happen” he thought to himself, so he got his cock out - ready for the inevitable changes that his son will go through. 
He wanted to see it all, maybe even record it, in hopes of not busting his fat load too early. 
But Simon was in for a big, big surprise. 

He noticed his son sweating and stirring in his sleep, and he soon awaked with his paw to his head - sweating profusely and inhaling deeply. 
“These were the first signs…” Simon thought to himself. 
 noticed how his daddy was sat across the bed from him, watching intently with his hard cock jutting up in the air. 
He had heard many tales from his father that his cock was big and it was normal for men to walk around naked as it “let all their musk out”. But seeing his daddy's cock right then and there, with that darkened face… Andrew felt his own loins tightening. 
Andrew uttered out words, barely able to control his voice - other symptom of the upcoming puberty. 
“D-Daddy, why are you here? And why do I feel so strange?” 
Simon put his paw around his 11 inch cock, slowly stroking his meat to his cute son that was going to turn into a man anytime soon. He made direct eye contact with him.
“It's alright, son. Your body is going through changes, and you just need to let it happen.”

Andrew could feel something in his loins changing, morphing even - and it was in between his legs. 
Letting out a deep, surprised cry that was far deep for his age, Andrew jumped out of his bed and looked down between his legs with horror. 
Meanwhile, Simon just balked in surprise - his cock jutting forth some puddles of precum to pool into his forest-like chest hair - but his own cock was nothing compared to his son's. 
Simon had already grown a cock that was thick as a tree trunk, and dropped down to the floor from its sheer weight and size. 
Most surprisingly of all, the entire foreskin was loose and veiny. 
Deep down, Simon knew the answer: his son was going to be the manliest offspring of his family. He barely had time to think as he raced away from his son's increasingly musky bedroom, to his own - his hands trembling from shock and anticipation as he gripped his phone and called his brother, Sam. 
He wanted all males to be present and accounted for during this very special time of his son's life, so he urged Sam to come as quickly as possible! 

As he returned to his son's room, he could not believe what he was seeing. So much so, that he dropped and shattered his phone on the carpet from sheer shock. 
Andrew’s puberty had progressed tenfold, and the lust with it. 
“But how?! In such a short amount of time…?!” Simon’s thoughts danced around his head, and he could barely piece anything together. One thing was certain, though: his son was the manliest kid he has ever laid eyes on. 
What he once viewed as a loving boy of innocence, was now progressed into this hairy man child. Hells, even the cock was bigger than his body - and nearly twice his width! 
His son's body grew taller and thicker slightly, yet even the small increase in height did nothing to compare to the size of his cock. 
Simon’s eyes stayed open in amazement as he watched the wiry hair of body hair thicken over every imaginable part of his fur. What started out as pubes on his body eventually amalgamated into this massive mass of black, seeping fur. 
In many ways, it was like a second fur coat. And it put his father's to shame.

At the base of his cock, his pubic hair grew like tendrils - thick enough to be considered roots, coiling and curling together as they grew further - eventually reaching up halfway Andrew's shaft. 
With the thick, unimaginable amounts of copious body hair, came a musk that would wilt flowers from its sheer strength. 
It was hard to discern at first, as the smell was on a completely different level that Simon wouldn't even think possible. 
Think that distinct earthy smell, but deep. So deep, infact, that it was even peeling off his wallpaper! 

Sweat poured profusely off Andrew’s body, and at first he was confused to what in the world was actually happening to his body.
His puberty was only just starting - as what would come next would change himself forever. 
He felt his heart pounding, blood pumping, and strength coursing through his veins like he was just at the aftermath of a strenuous workout. 
He watched in awe as he saw his hands increase twice in size, followed by the thickening of the forearm, and his bicep become fatter, more defined, before finishing with a sinewy touch. 
Once his other arm had gone through the same process, Andrew felt newfound strength powering through him. He felt like a berserker; a warrior in a storm. But the storm would not stop here, for his legs, chest and back were also popping out with muscle and increased body fat to go along with it. 
No longer was he a boy with the body one would expect of his age, he was a boy with a body of a Greek god! 
The body hair now completed his muscular form perfectly, and he felt himself becoming taller as he admired every inch of his new body, not even acknowledging his father's presence - too taken aback by the nature of his “special puberty”. 

Simon was even more surprised than before. He wanted to say something - comprehend the why, how, and what, but no words were able to leave his agape mouth as he leaned back against the peeling wall and sat in the carpet. This was well beyond his expectations, so much so, that he was even scared about what's to come next. 

Thick black hair sprouted from beneath his armpits, being greased up from musk. The hair grew so long that it peeked out from his arms. Once his nose caught a whiff of that heady scent, he raised his pit to discover a sinewy pit of black hair, all clumped together from sweat, and thick enough to touch his nose and get a full force waft of that manly scent. 
His own cock throbbed to attention; like a beast flapping about as it erected, the skin pulling back slightly to expose that thick cockhead. Still in a mix of amazement and reviere, Andrew looked down to see his fat cockhead hitting him in the chin, the precum lurching upwards and nearly hitting one of his eyes. Even the precum was deadly - every shot was not inferior to the last, infact his lust only kept on  growing stronger and stronger, until a pool of precum lied between his shocked father's feet. 

Everytime Simon tried to look up and down, he was met with the body of his son. Those fat, churning nuts hung low and were what only could be described as “behemoth balls”, probably housing so much powerful cum in them to destroy a few houses if his son wasn't to do that with his sheer strength of body instead. 

Andrew tried to say something, but nothing intelligible came out this time. Just deep room-shaking gurgles (a sound akin to an ape), accompanied by an insatiable need between his legs that is aching to be quelled.
But as he became aware of his libido, he didn't have any second thoughts. He simply needs a hole now. And the closest recipient to his desires? His father. 

Once he gained familiarity with his body after persistent admiration, so too did he gain familiarity with the nature of his voice. 
“You're nothing but a bitch now, Father.”
Each word was said in such a low, baritone and utterly demeaning tone - that it shook his own father with fear from the very core of his soul. Windows threatened to crack as Andrew stepped closer to his bitch, but he just kept whimpering in fear, out of reach of those burly arms. 
Andrew smirked, feeling the slight brush and tingle of facial hair growing on his face as he did so. 
“So this is what masculinity is all about”, he thought. 

Several loud knocks at the door prompted both male's attention. 
As soon as Simon was about to reach for the door, Andrew threw him in a merciless embrace - mashing his face together with so much hair that his father's entire head was lost of that dense jungle of grease. 
“Where do you think you're going, bitch?” Andrew barely spoke above a whisper, but even his voice then reverberated in his room several times. 
Simon got so intoxicated from that musk in a matter of seconds, that he just passed out. 
When Andrew tossed him back to the floor with nary an effort, he made sure to spit on him as a sign of dominance. 
“Who's the man now?” He said, grumbling, and taking hold of his door handle that was crushed from just his sheer touch. 
Grunting out in frustration, Andrew threw the door off its hinges and made sure to get a good eyeful of his uncle - who was probably frozen in fear and begging mercy before he threw off the door, as he still is doing now!
Andrew nonchalantly rolled his eyes, and pulled him a gruff embrace (the man nearly being knocked out of air in the process), and whispered into his ear as he his face was being shoved his hairy shoulders. 
“What man needs an obstacle like a door in the way? It's just keeping my away from my fuckmeat. Your brother won't save you now.”
Once he gave chance for his uncle to pry free from his grip, that useless fuckmeat was pledging mercy once again. 
“Please, don't do this! I have a wife and kids!”
Andrew laughed so hard that windows shattered and his uncle had to subconsciously cover his ears.
“Hahaha! That's what my father had, before he got a taste of masculinity. But now, his time as alpha male is over. It's my turn become alpha, starting with you - my own uncle - becoming my first fuckmeat! 

Andrew thrusted Sam’s head down, nearly smashing his face on the carpet from his strength. 
His gruff hands explored all of his uncle's hairy back, a fine black like his father but greying a little. I taking the smell with his nose, Andrew chortled.
“Such weak musk you have, little uncle.”
Once that huge cockhead spasmed around his uncle's hairy hole, he whimpered in submission and just accepted it. 

Andrew drooled out, happy that his cock had finally found a hole, slowly slinking in his stretched uncle's asshole inch by inch. He knew he wouldn't get it all in, but it felt amazing to the man-boy. His first experience with sex was fucking his own uncle's tight hairy asshole in a show of dominance, and it couldn't get any better than this. 
It was a good job Andrew's cock was producing a plentiful amount of precum, else the entry would be even more painful! 
Andrew gruffly forced his way in like a true man would, until his uncle could take no more, his asshole stretched to an immeasurable size to accommodate the thickness of his nephew's huge cock. 
Holding him up and across, Andrew thrusted his uncle's body up and down like a fleshlight, his cock garnering great pleasure as he did so - quivering and aching to seed into this tight orifice. 
Given that it's his first sexual experience, Andrew knew he wouldn't last long - his teeth gritting together as he felt himself approaching that sweet release of his male batter.
After all that initial pain, his uncle was euphoric with pleasure given that his nephew's huge cock hit his prostate like nothing else. 
“I'm going to cum!!! Time to fulfil your purpose, little fuckmeat!” Andrew cried, shouting so loud that people two doors over would be able to hear that bellowing cry. 
He felt his balls tightening, reaching off the floor to belch thick, milky substance straight up into his uncle's stomach - inflating it within a matter of seconds. 
His cum was not just goopy or thick, it was like a liquid! It came pouring down from the overflow, splashing all over the floor. 
As the seconds whizzed by in Andrew's amazing orgasm, the sea of overflowing cum reached up to his knees and he popped off his uncle with a loud ‘schlorp’ sound. 
Leaning back against the wall with his hairy pits raised, he let his afterglow musk fill the room as his uncle and father floated on a sea of his cum. 
His gargantuan cock jutted out several more loads as he leaned back, adding to the pool of cum swirling around him. 
Though his virility was far from expended, Andrew was tired from the transformation, the puberty, and the sex. 
Perhaps, when his uncle and father rise from unconsciousness, he could use them both as a fucktoy. 
Whatever his next step, he was looking forward to the future. 
Ah, puberty was amazing.
