While many would be content to lust over the wolf's pits, hairy chest and musky crotch which holds an 8-inch uncut cock under the most magnificent pube bush, what people fail to notice is the true extent of the wolf's needs. While he's jerking off over some needy fox face, his back slouched and arm leaning against the rocks, what's beneath his thick foreskinned cock which spurts precum like a faucet, and under his big balls that sway with his jerks? That's right, his fat fucking ass that only gets sweatier with each nose-huffing jerk.
This dude pumps his cock like a machine, so it'd make sense that he'd sweat up a storm.
If the overwhelming musk of the wolf tribe wasn't enough proof, then let this be a lesson: wolves fucking stink, and it doesn't matter what they do. If they so much as raise an arm, then their distinctive manly musk will come pouring out of their unshaven pits like a current which cannot be stayed in its course. It’s just as well, these 'fox visitors' (which may as well be the wolves' perpetual sex slaves at this point), need enough male musk running through their systems so that they can understand who's boss, and it enhances their libido to sexually satisfy the wolves to a point where these beasts would be begging for them to stop.
Because a masculine wolf beating off his 8-inch manhood in front of you, towering over you even (at a higher elevation), isn't enough for this young fox to know: his place belongs beneath them. He's got to smell in the musk first, get it flowing through his system, and then he'd be the ideal slave. As it stands, the fox's hands are firmly placed on the wolf's thighs, his eyes fixated on the wolf's foreskin rolling back and forth, his thick dick getting gripped tightly by the wolf's big hand, leaving only his pube-covered furry balls to swing freely about as he jerks it; an ideal opportunity at which the fox can assert his hierarchy... below the wolf, that is. The fox is short by usual standards, and that could be because of his younger age. As for the wolf, well... Let's just say that he is a man grown, and then some. This wolf's height is an astounding 7 feet, and even as he lays himself back against the grass, casually stroking himself off knowing that a young fox is watching him, it is clear that the wolf is far manlier and bulkier than the fox could ever hope to be even if he was the same age.
The fox's eyes grew wide as he watched the wolf jerk himself off, sometimes slowing his strokes to teasingly shake his cock in front of the kit, like it was something for the boy to play with. Even the feel of the fox's small hands against his warm, furry thighs was erotic for the wolf, who could get off from the sight of a curious youngster alone.
"Do you like watching daddy stroke himself off, young one?" The wolf said, his eyes burning with lust.
The fox felt his whole body shiver as he consumed the sight of the man before him, wafts of the wolf's crotch musk attacking his nose and relaxing his nerves.
"Yes, daddy..." He droned.
"You like watching big men beat themselves off, huh? Curious to see the 'white stuff' that comes out of my fat cock?"
The fox's mouth whimpered. His throat closed as more of the beast's potent musk took control of his senses.
The fox's tongue trailed over the beast's large balls, his other hand gripping the base of his cock, forcibly causing the wolf to stop jerking it and, instead, let his arms relax against the ground, knowing that the fox slut can handle it. But to say that he can 'handle it' would be an overstatement: this fox pays little mind to the throbbing of the wolf's cock in his hand, and instead thrusts his snout against his warm, fuzzy balls, inhaling deeply of his worked-up stink.

The man then throws his head back, groaning deeply from his throat.
"Awww, fuck yeah kiddo, that's the stuff..."
Then the fox's tongue travels farther down, licking the crack of his ass, making the wolf grunt out with surprise, his cock bouncing and throbbing of its own accord with every lick. 
"Damn, you found daddy's sweet spot, huh? Mph." 
It was clear the wolf was enjoying this spot of ass worship. It's about time he got some tongue action down there.
With one hand firmly pressed into the wolf's generous fluffy pube bush, the fox uses his other hand to push the wolf's left thigh apart, giving him more of an ass to dig his snout into. He inhaled the scent stored up there deeply as well, causing the wolf's eyes to roll in the back of his head, his tongue lolling out of his mouth. This heretofore unseen worship had attracted the much-deserved attention from the rest of the tribe and their designated fox slaves, as they had lots to learn about a wolf's sensitive spots.
Eventually the wolf decided to lift both of his legs, forcing the fox's head into his sweaty rump, uncaring to his muffles and cries. The wolf took great pleasure in feeling the youngster's face pushed up against his fat rump, the fox's tongue crazily slurping between his thick cheeks, into his big pink hole. There's no better source of musk than right in the wolf's sweaty ass itself. The fox's hands were now wrapped around the wolf's thighs, and every so often, the little slut liked pushing his nose against the wolf's asscheeks just to feel how fat they felt. He didn't know that manly men can be so thick! These wolves have so much cake!
Grunting heavily, the wolf blasted his spunk all over himself while he was getting a rimjob from a teenage fox who just did not know how to stop. His cock lurched and thick, heavy spurts of cum splatted in his face, trailing down his neck to his muscled chest, matting down the light hairs on them. His muzzle looked like it was dipped in cream, but that did not stop the wolf from licking it up with his long tongue which has a penchant for these types of situations.
Now that his big pink hole was soaked in a venerable amount of eager boy spit, the fox drew away from eating the man's musky hole with a deep sigh and set the big man's legs back down again. The fox clambered over the heaving wolf's body, his small hands basically the size of one abdomen and crawled his way up his muscled, cum-soaked body to kiss the man deeply on the lips. The wolf returned this kiss with a dark grunt, his cock flexing and flicking in its semi-hardness behind the fox's tiny, tail-raised orange-furred rump.
When the fox felt the warmth of the wolf's cock push against his ass, the boy moaned and his hole twitched instinctively, eager for the older man's meat. 
Knowing that there is no better time to strike, the wolf slowly pushed in his cock inside the teen's succulent hole, and the fox could feel everything entering his rear, down to the veins on this wolf's beautiful uncut meat.
Then, once he got halfway, he stopped slowly pushing in his meat and instead SLAMMED the fox's ass into his crotch, pulling him down by his hips. The little slut cried out in pain whereas the wolf was pigging out in lust knowing that his cock is inside someone who can barely take it.
"Breed that bitch, brother!"
"The little kid thought he got you!"
"Show those lowly whores what real men are made of!"
The wolf's face snarled as he listened to the encouraging cries of his men, getting more 'in the zone' of this act of male dominance.
His paws around the boy's lithe hips and lower body basically locked the fox whore into place and forced him to bounce in time with his new father's horny, lustful thrusts, which were more like stabs in the back. But eventually, the fox learned to love it - the pain subsiding from his virgin asshole being stretched like nothing else, and now all he wanted to feel was this fully grown man cock thrusting inside of him again and again.
But what these foxes have to learn is that they don't have a say in the matter; wolves own them. They can try to take advantage of them, but their feeble bodies and easily-grippable frames make for ideal fleshlights.
"Take daddy's cock, bitch," The wolf grunted out as he continued frantically thrusting into the fox's soft rump, spit flinging into his creased, pained face. 
The wolf's big balls slapped against the boy's ass with every thrust, his orange-furred rump not even visible underneath the layers of pube fluff his ass is buried in, not to mention the dark-furred milkers slapping against him time after time. The slaps of the wolf's balls against the slut's butt and clapping of his ass as he mercilessly pounded his cocksleeve was so loud that the entire tribe turned to listen and watch, multiple wolves frantically masturbating their cocks from the side of their cum and piss soaked loincloths.
"Give me your spunk, daddy!" The fox cried out, looking at the wolf with the wildest smile he's seen. The boy was blushing, but looked to be having the time of his life on a bouncy ride that is sure to end all bouncy rides.
This boy's eagerness caught the wolf off guard.
"Huh?! You want your daddy's cum, slut?!" The wolf started thrusting so hard that the fox was starting to tower over him now, his hips bucking wildly in the air. From a distance, it looked like the perfect sacrifice for the tribe. A small fox buried on a massive wolf boner, fucking on a cliffside, the fox raised up into the air by the sheer power of the wolf's cock and hips alone.
Overcome with love for his slave, the wolf grabbed the fox and flipped himself over so that he could really pound the kid into the dirt.
"Take daddy's pups, bitch!" The wolf snarled out as his cock exploded geysers of cum inside the teen's slutty hole and, in the heat of the moment, the wolf couldn't help but make out with the boy as he did so, at last professing his love for him with a deep blush and hungry look on his face that probably won't go away until he's been milked two more times.
Because wolves are just superior.
