Musk and Muscles

The large gray-skinned beast of a man bent down once more, over a ton of massive weight resting on his shoulders as he came down to a full squat position. His skin was a rugged surface of protruding muscles of grandiose thickness from a lifetime of lifting. The cracks in his skin impressed the illusion of dryness as he exercised, but that belied just how moist the ungulate truly was. Every time he lifted weights he perspired with such intensity that even at that moment, as he brought his butt close to the ground, countless drops of sweat fell from his arms, legs, face, and crotch to form a small puddle that had been building slowly. His genitals dangled between his legs and his ass was in full view, exposed with no covering to conceal his nakedness nor mask the tremendous musk given off by the hulking male. The odor he gave off would make anyone cringe and cough and recoil in disgust at the rhino that obviously hadn't bathed in well over a month.

He grunted loudly as he pushed himself up, his legs straining, veins popping out of every corner of his body as he hoisted the unimaginable weight up until he was standing straight. At 9 feet tall, he was truly an intimidating figure, massive pecks like bulbous mountain peaks and giant biceps and forearms that looked as though they could crush rocks. His back muscles were like a topographical map of some landscape full of hills and peaks. As he completed his latest rep, his brow was furrowed with an intense expression as he grit his teeth and grunted as he exhaled from the exertion. His eyes stared forward with ardent passion for his lifting, his lips curled back, seeming to attempt to reach the enormous ivory horn at the end of his muzzle. He was intimidating and off putting for most random people who came across him, fearful and evasive due to his massive frame and sickened by his pervasive musk.

However, the giant, muscle-bound behemoth chanced upon someone who marveled at his hulking stature and who found his ardent stink appealing. As he lowered himself for another rep of squats, the rhinoceros was being gazed upon by a fox/otter hybrid who sat on a bench in the pachyderm's private gym and watched with singular fascination towards his boyfriend's workout regimen. Unlike the rhinoceros who was a towering mass of muscle, the fox/otter was lythe and short, around 5 and a half feet tall and could barely instill timidness in a child. He sat as naked as his mate, a short, stubby muzzle with similarly stubby ears typical of his species. His paws looked fairly typical of foxes save for a little webbing between the digits and his tail wasn't nearly as bushy. His fur was brownish red, a good mix of fox and otter colors.

The fotter watched with amazement as his boyfriend brought himself to squat once again, a huge barbell with numerous weights that would flatten the smaller fur, only to immediately return to a standing position with an audible grunt. 18 reps and he still had two to go. The fotter wagged his tail, anticipating what came next. Unlike most people, he felt no fear or disgust towards the rhinoceros. Instead, he saw his giant, well-built frame as almost godlike, crafted to perfection with inerrant detail. He marveled at his flexing thighs that spanned a wider girth than the fotter from shoulder to shoulder. He was entranced by the pulsating variation in musculature of the pachyderm's various body parts. But most of all, he fixated mostly on the behemoth's infallibly-shaped rump, the movement of the inviting tail hanging and swaying over it, the curvature of the two perfectly shaped orbs, the crease glistening with sweat that dribbled down constantly over the surface, and of course the shadow formed by the close proximity of the separate gluts failing to hide the giant protruding anus in between.

He licked his lips to clean the drool accumulating from his anticipation of his partner's rest period. Unlike most other people who recoiled from the rhino's stench, the fotter not only embraced it but longed for it. The gym was warm, hotter than the outside usually which allowed the rhino to work up a sweat and exacerbate the odiferous chemicals exuding from his body. Being a private gym, it allowed him to workout the way he preferred: nude. From start to finish after every set he performed his musk got more and more powerful. Even now as the fotter watched him go for rep 19 the smell of unwashed rhino sweat, body odor, arm pit, crotch, and ass wafted over to the much smaller fur and tickled his sinuses and sent erotic jolts to his crotch, igniting his lust. His cock was hard and had been since the workout started. Oddly enough, even though he spends almost as much time in the gym as his mate, he never uses any of the equipment. In this aspect of the relationship he has a very specific and thoroughly enjoyable job.

The ungulate finished his final rep before setting the enormous barbell back on the specially crafted equipment. "Whew! Yeah! That's what I'm talkin' about." He boasted as he patted his ass and felt up his thighs to admire his hard work. He turned to face the fotter, his perfectly sculpted muscles bulging with every movement. "Ain't that right, Demi? You love what you see, don't you?"

Demi, a pet name for the fox/otter's real name, Demure, gaped at the rhino hungrily with his tongue lolling out. "Oh, yes! You're so beautiful Big Daddy!"

"Heh, damn right!" Shortly into the relationship, Demi began referring to his pachyderm boyfriend as Big Daddy or Big Papa and the rhino was agreeable. Big Daddy stepped over to a body-size mirror near where Demi was sitting and started flexing, showing off his toned physique. "Nobody's got a body like mine." He flexed his biceps, enjoying the build so much that he leaned over and kissed one. After getting a whiff of his sweaty funk, he leaned into one of his pits and took a sniff. "Whew! That is ripe! All right Demi, clean up your Daddy!"

"With pleasure!" The fotter didn't waste a second, sprinting to his feet and rushing to Big Daddy's side. He embraced the large man, unable to fully wrap his arms around him, but holding him tight as he brought his muzzle right into the rhinoceros's arm pit. The entire underside of his arm pit was completely coated in musky sweat with the majority of it culminating in a mass of long hairs that occupied the area, matted and basted in perspiration. Big Daddy kept his arm raised to allow Demi access to his funky pits. Demi opened his muzzle and pressed his nose against the putrid scented surface as he stuck out his tongue and began lapping up the rancid liquid, performing his duty when it comes to Big Daddy's workout; act like a towel to lick the profuse sweat that accumulates on his body. The job is mutually beneficial as it allows Big Daddy to workout more efficiently and Demi gets an erotic high from the copious pheromones present in the excretions.

Demi eagerly consumed a mouthful of aromatic rhino sweat and immediately felt his body heat up from the zesty flavor. His pits were particularly flavorful and spicy, like a mixture of garlic, onion, and various spices rubbed forcefully against the skin and allowed to sit and fester over time. The taste warmed the fotter's nether region and he shuddered with lusty delight as he continued with his duties. He licked first around the hair, the glisten of sweaty skin fading as Demi drank it up. Once the more or less naked skin was taken care of, he opened his muzzle wider and engulfed the swath of hair and began sucking away at the foul liquid clinging to it. The amount of accumulated sweat filled the fotter's muzzle and he gulped it down without hesitation, the flavor burning his throat and igniting a fire in his ass. His paws wandered over Big Daddy's body, one paw tracing the various hills and valleys of his back while the other explored the deep crevices and hard-as-diamond protrusions on his abdomen. The powerful stench and taste emanating from his boyfriend escalated his lust as he attributed it to such a powerful creature of varying muscle tone.

"Yeah, that's right, feel me up!" Big Daddy said confident of his figure. "You enjoy this perfect body, don't you? You enjoy the taste and the feel."

Demi eagerly dug his nose in while trying to get every last drop of sweat, burning as much of that spicy scent onto his nose as he could. When he was finished, he moved over to the other pit to repeat the process, his belly slowly filling with the potent perspirations of his odoriferous boyfriend. Even when Demi had sufficiently licked up Big Daddy's secretions, the spicy musk still lingered heavily in the dank crevice. Demi would be satisfied just burying his nose in the stench drenched corner, but his job there was done and he was expected to continue. Much to his joy and anticipation, the best was yet to come. So the fotter moved over to the rhino's chest and lapped up the glistening sweat coating the large protruding pecks. He picked the droplets off the matted hair on his tongue, the funky flavor making him shiver with delight. He continued down towards his abdomen, moving quickly to soak up sweat on his torso as quickly as possible so that he could proceed to the two sweatiest locations on the pachyderm's body.

"Mm, yeah, get down there Demi. Daddy's feeling particularly wet in that area. Gonna need to work hard to lick it all up. And right now it's particularly peppery."

Demi flexed his cock as he felt a surge of sexual excitement from his boyfriend's descriptions and he was anxious to begin cleaning his crotch. He hurried through the hills and valleys that made up his ripped abs until he was inches from the rhino's pride. A huge, naked phallus with a mushroom-shaped head and covered sparsely with curly pubes, dangled long and limp from his smelly crotch. Below that hung a pair of rhinoceros testicles the size of coconuts, densely packed with pubic hairs and too large for the fotter to hold in both paws. His entire package was drenched in sweat and as Demi's nose came closer he confirmed that the smell was especially fetid at the moment. He kept his mouth shut as he shakily breathed in the dense, acrid musk and moaned in ecstasy while his groin tightened.

He gripped the enormous ballsack and held up the shaft to gaze upon the glistening glans surrounded by spongy flesh on the rim. Demi moved his muzzle forward, constantly inhaling the offensive odor, moving his lips towards the urethral opening. He stuck out his tongue and jammed it against the tight cockhole, a sample of salty liquid stuck at the edge. Once he made contact, he began lapping up the tart liquid along the surface of the glans, his hair standing on end and his body shaking. He licked slowly along the surface of the large phallus, taking his time while moving downward towards his crotch. The ministrations tickled his mate's sheath, the rhino warming with sensual emotions and growing hard in front of his boyfriend.

"Mm, yeah, get it all. Lick it all up. I know you enjoy cleaning up my massive, bulging cock."

Demi moaned in response, reached his mate's groin, and paused a moment to sniff at the damp intersection between his leg and his dick. The smell was so intense it made the fotter's mind fuzzy and he felt a false orgasm approaching. He suppressed the urge to get off for the moment and continued to clean his boyfriend. He moved down the large sack, lapping at the giant surface, each hair providing sufficient fluid to stimulate his taste buds and his arousal. He licked up the front, spending a large amount of time at the intersection of his penis and his balls before moving down to the underside. Several hairs had accumulated a profuse amount of sweat and Demi engulfed the small patch, and hungrily sucked down the tainted excretions clinging to it. He continued to clean the scrotum, reach the backmost portion right before he reached the perineum and stopped.

"Good job. Now... you have permission to clean the sexiest part of my body."

Demi's ears perked up and his heart beat erratically. Despite a reservoir of the rhino's remnants ruminating in his belly and intense smell and taste of rhino musk still assaulting his senses, the fotter was never fully satisfied until he got to service the sweatiest part of the rhino's body. Demi moved around until he was behind his mate, staring up at the large, hard, perfectly crafted buttocks. He licked his lips and whined lightly as he moved towards the right glut, a thick coating of sweat glistening in the light. Hastily, he stuck out his tongue and dragged it upward along the surface, practically inhaling the smelly fluid as he soaked it up. The musky flavor was similar to his chest with a noticeable hint of the bitter taste of ass. He repeated the act, licking up more butt sweat and letting the flavor spark his taste buds and ignite his arousal. His cock was hard as stone, his knot fully formed with pre seeping out of the head while he licked along the rock hard surface away from the crack until he reached the end. Once finished, he moved to the other butt cheek and removed the accumulated perspirations, leaving behind a thin layer of his own spit which at this point smelled like a month old jock strap.

"Yeah, clean that ass Demi. Don't leave any sweat on my rock hard ass. Make sure to get into every corner."

Demi did as bade until the pachyderm's posterior no longer shined and with nothing left to clean it was time to move on to the main event. The fotter whined again as he stared at the moist crack. He reached up and grabbed Daddy's tail, moving it aside to grant him access. He leaned his face forward until it was inches from the damp canyon and he closed his eyes, inhaling deeply the bitter, pungent aroma of hot, sweaty, unwashed rhinoceros ass. The smell was explosive to the fotter's sensitive nose and it burned at the initial stimulation, but the effect on his lust was pronounced, causing him to groan and fidget as his crotch burned with intense orgasmic delight. Craving more of that stimulating scent, he sniffed again, inhaling more of the pachyderm's redolent backside and once again shivering as his crotch ignited with sexual passion.

With his nostrils burning with spicy rhino butt stench, Demi stared longingly at the wrinkled and tightly clenched anus staring back at him. Demi's favorite part of being Daddy's towel was cleaning off the source of the rhino's smelliest and most flavorful musk port on his entire body. The tight ring exuded such a rich assortment of odoriferous pheromones that just one swipe of the fotter's tongue along the rhino's back entrance was enough for Demi to lose himself in his lust. Anxious to get the taste of rhino ass in his mouth, Demi licked his lips and pressed his nose against the large beastly stinkhole and inhaled one last, long breath, starving his lungs of oxygen and filling them with ass stink. He shivered intensely and trilled, his eyes rolling into the back of his head. Foggy with salacious drives, Demi finished his work.

He leaned down under the rhino, stuck out his tongue, and dragged it from the giant, hanging testicles along the gooch and up to the base of the wrinkled tail, licking up large swaths of sweat and passing over the tight hole in the process. He tongue was awash with vehement flavors, salty, spicy, bitter, and rich with the familiar taste of both rhino and ass. The stench of Daddy's rear from never showering for some time and continuously working out was so exquisite that Demi couldn't bear it and coughed up a little as his throat adjusted to the intensity. But the response from his groin was equally acute and his whole crotch tingled with sexual prominence that his legs were so week he could barely hold himself upright.

"Yeah, baby! Lick that ass! Clean that funky sweat from between my butt cheeks!"

Demi took a couple of breaths before he joyfully repeated the process, absorbing more musk-ridden sweat into his mouth, accumulating it in his muzzle, and slowly swallowing it, letting the flavor spread throughout his inner maw as it pooled in his belly, the fotter rejoicing with the knowledge that the rhino's stink is settling inside of him. He did it again, licking up the sides of the crack, the taste just as prominent and just as stimulating to his cock, but with each ingestion of smelly rhinoceros excretions the negative impact on Demi's senses was diminished and he was able to dry the toned ass consistently. With a steady rhythm, Demi brought his paws up and grabbed onto Daddy's ass cheeks, gripping them hard, but with little success in affecting their form. The rhino's gluts were so well-toned that they felt less like muscle and more like actual stones.

"Mm, how you like Daddy's ass, Demi? You like those round, stone orbs? You like having a boyfriend with such a strong, perfect ass?"

Demi wanted to acknowledge him, but he wasn't about to interrupt himself from filling his muzzle with more aromatic pachyderm stink. The rest of the crack was fairly dry of the rhino's secretions, but the stench from the wrinkled sphincter hardly dissipated and the musk emanating from it was driving the fotter wild with lust. No matter how much he licked he wouldn't be able to clean the rhino's rosebud, but he didn't care. It was providing him a powerful and natural aphrodisiac and making him sexually voracious. With Daddy's crack 'clean', Demi focused his attention entirely on the puckered rink. He positioned his muzzle right under the closed cavern and began lapping away at the pungent back door, licking along the sides, over the ridges, along the wrinkles, and up over the secured entrance. Daddy needed to finish his workout, but the fotter was just so good with that tongue.

"Mm, damn baby! Ooh, that feels good!"

He responded by clenching both his cheeks and his asshole, giving Demi something new to stimulate his arousal. The clenched ass cheeks squeezed his muzzle while the tighter puckering of his sphincter drew his tongue towards the inside. Demi shuddered with delight and kept licking, this time more closely around the entrance, hoping to gain access to the inside. Daddy relaxed his gluts for a few seconds before tightening them again, showing off for the fotter in such a way that the rhino could also enjoy.

Demi continued his oral ministrations for only a short while longer before Daddy finally decided his needed to finish his last workout. "All right, that's enough," he said while shoving Demi's face off of his asshole. Demi whined in response, but Daddy flashed him a grin. "Don't worry. I got one more workout and you'll get more of my smelly ass to clean after."

With that, Demi started wagging his tail. "Thank you, Big Daddy."

"Of course. I need you to keep my ass dry."

After flexing a little more for himself, the pachyderm stepped over to a reverse sit-up bench and along the way Demi noticed his mate's cock was bouncing around and getting hard. He hadn't reached fully erect yet, though as at full mast the monster's organ was about 16 inches long and 4 and a half inches wide at the base. Demi felt his climax edging closer and closer with every sniff and every lick of that hot ungulate body, even without laying his paws on his junk. A short while longer and Demi wouldn't be able to hold back the torrent of fox essence that was building up inside him. If Demi could hold out just a little bit longer, he'd be in a position to amplify the sensations of his upcoming orgasm immeasurably.

Daddy got into position, though it was fairly difficult with his hardening member getting in the way, but he was able to tuck it under and get his legs in position for his last workout for the session. Demi quickly stepped over to the equipment and watched as Big Daddy began descending, then ascending, and repeating the process once, twice, thrice, and over and over again. Every time he bent forward, his ass clenched and the musculature hardened like petrified stone. Demi's cock twitched in anticipation for more of that rhino's ass on his tongue, his groin afire with that sexual tingling. After 100 reps, Daddy stopped and took a short break, breathing heavily while he checked out his body in the mirror, clenching his ass and flexing his leg muscles.

"Oh yeah! Keepin' perfection at its highest level," he said aloud.

"I don't think perfection does your body justice," Demi blurted out almost subconsciously.

Daddy turned towards his mate and grinned salaciously. "Damn! You're really horny today, aren't ya?"

"Oh, yes sir, I am."

"Heh, well hold on a little longer. You'll get more rhino than you can handle."

With that, Big Daddy returned to the bench and began a second set of 100 reps. Demi watched as every muscle from his back to his legs to his butt to his stomach flexed and relaxed with each rep, accentuating the pachyderm's hard work and dedication. His body was glistening again with hot, salty, lust-inducing rhinoceros sweat that Demi really wanted to stimulate his taste buds. His butt was beginning to glow again and as the stink of the rhino's odor permeated the gym, Demi's cock pulsated like a time bomb close to exploding. With his second set done, he took another break to catch his breath, relax, and flex for himself and his boyfriend once again. After a couple minutes, he climbed back onto the platform and prepared for his final set.

"All right, Demi. Last one and then I need you to go to work."

Demi let out a noticeable moan as Daddy began his final set, pushing himself to finish and seemingly anxious to finish his final rep so he could get his ass licked. His cock had softened slightly as the workout helped him focus, but the prospect of the fotter's tongue and muzzle glued to his posterior kept him from going limp and encouraged him to finish quickly. He had a little trouble finishing the final few reps, but once he did he quickly stepped down, muscles bulging with veins popping out and glistening with sweat that dribbled down his skin and formed small puddles on the floor. He leaned on the bench and pointed his butt in Demi's face and turned to face his mate. "All right... Demi. Get... to work," he said with a grin in between pants.

"Yes sir!" he replied racing to Daddy's rear end. The rhino lifted his tail to provide easy access to the fotter, whose muzzle was mere inches from the wet, musky surface in seconds. The smell immediately brought his decaying climax back up, the bitter and putrid aroma of rhinoceros ass stimulating the smaller mammal's insatiable desires. He opened his muzzle and dragged his tongue up along the sides, gathering up the salty mixture of rhinoceros secretions, the taste just as rancid as a few minutes ago, a testament to the powerful musk of an unwashed rhinoceros. He quickly cleaned the sides so he could focus on the crack, shoving his muzzle roughly against the surface right under the sphincter. He took a sharp inhale of the rhino's odiferous anus and shivered with lascivious abandon, his crotch burning with erotic stimulation and aching to release the rising level of fotter spunk in his scrotum. He quickly stuck out his tongue and dragged it up the middle of the sweaty rhino's dank, musky crack, the stink of his boyfriend's ass clinging to his taste buds. The mixture of salty, bitter, and spicy flavors burned his olfactory and gustatory nerves with such profound intensity, it was as though he hadn't spent the last couple hours cleaning the rhino of his perspirations. He licked again and again and again, along the sides and down the middle, eagerly swallowing the essence of his mate and no matter how many times he licked, the flavor barely changed. Big Daddy's ass was like an eternal source of stink-filled, pheromone-laden flavors and scents, a haven of erotic euphoria for the insatiable fotter.

With the rest of the rhino's rump relatively dry, Demi could once again focus on the most egregious source of lusty odors. He lapped the tight bud slowly, making sure every inch of his tongue got a sample of the pachyderm's hole. He shuddered as he continued to lick away at the wrinkled back entrance, unable to repress the powerful musk. Intoxicated by the rhino's ass stink, Demi enclosed his lips around the puckered hole and began to kiss it, his tongue continuing to explore and prod at the ring, trying desperately to penetrate it. Big Daddy was immensely enjoying the fotter's treatment, his cock growing harder as his anus was stimulated by his boyfriend's masterful ministrations. He felt his mate trying to enter him with his tongue and the sensation was making his dick pulse with unfathomable lust. His body was fatigued from the workout, but his desire for his reddish-brown boyfriend made him weak.

"Urgh! I can't take it anymore!"

Demi felt the hole begin to loosen up, but before he could spear his mate, Daddy stood up and turned around. The fotter got knocked lightly in the face by the rhino's 16 inch dong, but didn't get much time to enjoy it as he was lifted off the ground. He didn't mind though as it meant it was time to get wrecked by the massive beast. Daddy carried him over to the bench press, though he'd removed the bar in preparation for this moment. He let the fotter down, letting him flop down face up onto the bench and quickly grabbed his legs and held them up.

"How can you be so goddamn good with that tongue?"

"Heh, when you're properly motivated, you just let your body do the work."

"Hm. Well I'm about to get to work on your body, little man, so prepare yourself."

Demi let out a whimper, his heart beginning to race as Big Daddy leaned his face down to Demi's ass. Like Big Daddy, Demi also refused to shower and so he also reeked of musky odor and although his scent wasn't as strong as the rhino's, it certainly made the big guy happy. He sniffed the fotter's back door and grumbled erotically, taking another sniff of the dirty asshole, the scent sending him into an almost rut-like state. He leaned forward and began licking the tight hole, tickling Demi's rear end and sending jolts of pleasure through his lower body. His climax was teetering on the edge and it wouldn't take much to drive it over. Daddy continued to lap up Demi's behind, but the large animal produced a large amount of mucus and left a generous coating of rhinoceros drool caking the fotter's butt. He pressed his tongue forward and separated the anal ridges that sealed up that back entrance and pressed forward, entering his boyfriend with his large muscle. Demi groaned with pleasure and tried desperately to keep from releasing before the rhino had inserted something larger into his ass. Daddy coated as much of the sphincter walls with his viscous spit and once sufficiently lubed up, he retracted his tongue, smacking his lips as he raised up and stared longingly towards the smaller male.

"God, you're hot. You ready to take my hulking monster?"

Demi nodded emphatically. "I'm ready." Though eager, his heart beat nervously. Though it had gotten easier over the many times Big Daddy had fucked him, it still hurt every time he entered him and every second inside of him was quite uncomfortable. But no matter how uncomfortable it was, what that beast of a man's cock did to his body to stimulate his sex drive made it all the more welcome. Daddy climbed on top of Demi, using one hand to guide his massive equipment to the outside of Demi's small, tight ring. His head pressed up against the slickened hole and Demi took a few shallow breaths. Daddy smiled menacingly down at his helpless mate, making the fotter's heart beat faster and his groin tingle with anticipation.

Without any hesitation, he pressed his hips forward, attempting to push the fotter back along the bench. With his free hand, Daddy grabbed Demi by the shoulder and pushed him down onto his swollen cock. Demi felt the pressure in his ass build to an intense heat as the rhino's glans began to separate the fotter's sphincter. Before long, the large cockhead had opened Demi wide enough to press forward and with an agonizing fire spreading through the fotter's ass, Daddy managed to press forward and enter his boyfriend. The pain cause Demi to scream as he was speared by the immense phallus, the initial penetration always a challenge to withstand, but he always managed. Daddy quickly moved his hips forward, stuffing his cock inside the tight and moist innards, inflating Demi's intestines. As his dick became encapsulated by the warm, damp confines of the fotter's colon, the nerve endings fired with intense pleasure that he moaned loudly, his maw open and not attempting to control the flow of drool from his muzzle. A large swath of spit flowed freely from his maw and fell hard on Demi's neck and face, coating it and even catching a little in the fotter's mouth as he cried in pain. He didn't mind though as it just added to the intensity of the encounter. As Daddy quickly pushed further inside, he pressed up against Demi's prostate and the pain and discomfort of being inflated was augmented with explosive sexual pleasure and his cries turned to loud groans.

Inch after inch was buried in the smaller furs rectum, the large intestine was filling out forming a bump in Demi's belly. The pressure on his prostate was intense and his crotch burned with lascivious stimulation and his cock was pushing closer to blowing the fotter's load. Just short of the base, Daddy inserted almost his entire length into his boyfriend, the pressure squeezing back on his cock making him grit his teeth and groan ecstatically. He brought both arms over Demi's head and held himself up using the bench, the warmth of the gym and the staleness of the air enhancing the musky odor that radiated from the rhino as he hovered over Demi. The fotter couldn't escape it and he didn't want to, the smell making him writhe underneath the pachyderm in insurmountable lust as he was held in place by the monstrous dick.

Without waiting for his mate to acclimate, the rhinoceros pulled his hips back casually, removing almost half of his thick penis before shoving it back in. The motion caused Demi a fair amount of a burning ache in his ass, but also further stimulation of his prostate. Daddy repeated the motion, this time with more force to his thrust and slowly he built up a rhythm where each motion back and forth was enough to rock the bench beneath them. As Demi's ass was plowed, every nerve ending in his anus augmented the inescapable sexual torment on his prostate. In addition, the pachyderm's belly was rubbing up against the exposed and sensitive flesh of the smaller, knotted cock bellow. Mixed with the rhino's unfettered musk driving the fotter wild like a female in heat, Demi couldn't hold back anymore as his crotch exploded with sexual tension.

Demi reached his peak, trying to hold off his climax as long as he could, but sensing his vas deferens and urethra accumulating a warm torrential flood of fotter spunk. The pressure built for several seconds, the physical sensation immeasurably vibrant, and soon enough he couldn't hold back any longer and a long, hot, chunky shot of milky fotter jizz shot out and stained Demi under his chin. He cried out in orgasmic bliss as he fired a second shot just as enjoyable as the last. A third shot hit passed his head leaving a string to fall over his face with a little coating his mate's belly. As Demi enjoyed the throws of ejaculation, Daddy was grunting hard, shaking the bench like an earthquake as he wrecked his boyfriend's asshole, his mouth ajar with strings of drool dribbling out and hitting Demi on his muzzle, face, and even inside his mouth. Some of it mixed with Demi's juices and the fotter felt an extreme warmth fill his body as he continued to unload his balls onto his belly and chest.

Daddy was pumping harder now as Demi's climax started to wane, though he was still ejecting several smaller spurts of male milk on himself and his mate. Soon after, his own orgasm ebbed away, leaving his balls empty with the sensation that a small chunk of sperm remained stuck just inside his urethral opening. He wanted to jerk off to coax it out, but with his boyfriend rocking him back and forth like a sex toy, he couldn't do anything yet but let the rhino get off first. The warmth was taking its effect because Daddy was sweating profusely now, small driblets of perspiration fell from his chest, his stomach, and his neck and soaked into Demi's fur. He continued to hold his muzzle open to grunt and moan and coat the small mammal in odiferous spit.

Despite his orgasm abating, his prostate was still being pummeled and his cock was being rubbed, making the fotter especially sensitive under the larger man's weight. He shuddered at the feeling, hoping Daddy wouldn't take long as the sensation was overtly taxing on his sensitive and used cock. The rhino was pumping fast, eager to release his seed into his mate's guts and using every ounce of strength and stamina that remained to coax out his own climax. Every muscle was tight and flexed, his hips slapped Demi's ass, and his body a factory of abundant sweat and musky funk. As he plowed harder and faster, the bench banging underneath, Daddy opened his eyes and watched as a sliver of spit fell from his maw into Demi's waiting muzzle.

"God- *pant* ugh- You're ass *groan* feels so good! Take it- ugh- Demi!"

Demi smiled under his boyfriend's massive frame, his legs gripping the rhino's waist to keep them up in the air while he finish destroying his ass. Before long, Daddy's breaths were ragged and inconsistent. He eyed the smaller fur hungrily for a while, before leaning forward and connecting his muzzle with Demi's in a passionate and animalistic kiss. His muzzle was quite a bit bigger than Demi's, though and so may as well have been practically trying to eat his boyfriend's mouth. Demi adjusted to make it easier for the rhino to access his maw and once they were kissing, Daddy thrust out his tongue, filling Demi's maw with the thick, slick organ. Demi happily accepted the pachyderm's appendage into his mouth and as the rhino poked and prodded he filled the fotter's muzzle with his own saliva, which Demi sucked down with glee.

Daddy's pounding was starting to slow, but his thrusts were getting harder, meaning he was close. After a few more seconds of frenching, Daddy pulled away and began grunting hard with each thrust, gritting his teeth as he pumped harder and harder. "God, your mouth *grunt* tastes like ass!" he jibed.

"Heh, thank- ugh- you!" Demi relaxed a bit, letting Daddy use his body as he wanted, the thought of being his boyfriend's play thing keeping him hard despite his recent orgasm. Daddy seemed to be concentrating on achieving orgasm, his body glistening with sweat that soaked his used mate and stunk up the air around them. Demi inhaled through his nose in between thrusts, sniffing the rhino's odor to enhance the experience leading up to Daddy's release.

It only took a couple minutes, but Daddy's grunts turned into roars, his rhythm slowed considerably, and his thrusts were more powerful than ever. He was practically throwing Demi back and had the fotter not had a giant penis shoved up his butt, he'd surely have gone flying. With a final few grunts, Daddy arched his back, lifted his head back, and screamed in triumph as he shoved his enormous phallus deep into Demi's bowels and fully mated his boyfriend. After pausing a few second, he began making slow, rough thrusts, using the fotter's ass as a milking machine. Demi felt a warmth spreading throughout his belly as his intestines were filled with rhino cum. With his innards plugged so tightly and the pachyderm's seed so voluminous, it spread deeper into Demi's dank cavern, pushing further and further in as more and more rhinoceros semen was expelled from Daddy. Pump after pump he ejaculated hard into his mate's belly, emptying his balls for all they were worth.

Finally, with one more lazy thrust, Daddy hilted Demi and stopped thrusting, relaxing his head and back so that he lay panting over Demi's body. He was once again drooling on the fotter's head, who just smiled and sniffed the putrid essence exuding from the rhino. Daddy's jizz pooled inside Demi, warming his bowels and tickling him sensually. After a few minutes of catching his breath, Daddy lifted his head and shut his muzzle, ending the leaky faucet that was his maw. His boyfriend was soaked in sweat, drool, and a little fotter cum and stunk of both rhinoceros and fotter musk.

"Mm, that's the way I like you. Spent, stinking almost as much as me, and ass full of my cum."

"Thank you so much, Big Daddy. That was amazing."

Daddy leaned back. "I aint finished yet." Demi cocked an eyebrow as Daddy placed a hand on his belly and held him in place as he extracted his phallus from the fotter's entrails. Demi moaned loudly as the cock slid out of his intestines, his guts deflating and his ass stinging. When Daddy's glans finally exited with a pop, Demi's anus began leaking rhino semen that dribbled down his tail. At first it flowed like a small waterfall, but then depreciated into a light drizzle slowly out of his ass and continued like that for some time. Daddy stood up, his cock still semi-hard and wet with cum as he stared down at Demi. "Fucking you gave me a hard workout and my ass is sweatier than ever.

"OK, um..."

Before Demi could move, Daddy stepped around and lifted a leg over the bench, pointing his chiseled butt down at Demi's face. The fotter stared up lustily at the glistening ass, drops of butt sweat dribbling off the pachyderm and into the fotter's fur, mixing the fluids currently soaking his fur. Daddy lifted up his tail and quickly bent down, Demi barely having time to react, let alone do anything. The giant rhinoceros ass pressed against the small fur's muzzle, holding his head down against the bench. The pachyderm continued to lower himself, letting his weight go and forcing Demi to open his muzzle to fit the large posterior. As his boyfriend's weight came down, Demi was now stuck with his mouth open and covering the rhino's sweaty anus, an intense heat radiating from the puckered back entrance. "Get to work, Demi."

Trapped under the weight of the brawny ungulate, Demi huffed a deep breath in through his nose and with rhinoceros ass taint pressing against his nostrils and nowhere for any fresh air to reach him, he was forced to breathe in pure, undiluted, and excessive butt stink. His cock immediately flexed, his knot forming and pulsing, and his crotch tingling with newfound sexual drive. His fur stood on end as the potent musk riddled his mind and his tongue darted out, making contact with the large anus now sitting within his maw. The flavor was unscalable, a mixture of spicy, salty, and bitter fused with the unforgiving aroma of rhinoceros odor assaulted his taste buds, seeping into his mouth and inducing a tingling sensation on his tongue. The mixture of smell and taste sent jolts of pleasure through his body, culminating in a fiery longing in his groin to once again release his seed in an explosive climax.

The odoriferous sweat that accumulated during their harsh fucking dribbled down the crack and onto Demi's nose, enhancing the erotic effects Daddy's ass was having on his olfactory nerves. He shuffled under his boyfriend, barely able to move but unable to control himself as his ass and groin were alight with a building orgasm. His tongue went wild as it started rubbing up against the wrinkled surface, running up and down, side to side, along the top and underneath, at the tip and towards the back where the majority of his taste receptors were. He moaned constantly as the stink enveloped his senses, the flavor of the rhino's musky ass was now infusing into the fotter's own saliva.

Horny and hungry, Demi worked more forcefully as he pressed his tongue hard against the cracked skin, the organ touching nothing but rhino anus while more sweat continued to dribble down with a little seeping into his muzzle and inciting a new flavor to induce further sexual tension. The taste continued to dance on his tongue with no loss of the intensity or effectiveness on his libido. The pheromones were just as prolific as the flavor and scent with which they were attached. His sex drive led his tongue to the center of the stench-filled rosebud as it began to poke and prod at the closed entrance trying to attain a sampling of the most exquisite flavor the pachyderm's butt could produce. Though Daddy kept his asshole clenched, Demi noticed it was somewhat relaxed compared to earlier and he figured he might have better luck gaining entrance now. Daddy moaned up above, flexing his asshole randomly as Demi treated it to his oral ministrations. The large ungulate smiled as the wet organ graced his sensitive skin, basking in the sensation as he enjoyed the effects of the day's exercise. He flexed his biceps, his hamstrings, his chest, and his abs, feeling up the pronounced musculature as the small fotter below inhaled the olfactory effects of his sweaty workout. Before long, after a brief clenching of the tight orifice, it relaxed a bit more than usual and long enough for Demi to take advantage and drive his tongue hard against the hole until it slipped through and managed to descend into the dark, dank depths of Daddy's glorious tailhole.

"Ah, fuck! God, that feels good. Yeah, get in there. Clean your Daddy good."

Demi loved hearing Daddy bark orders at him, but he needed no words of encouragement, and thrust his tongue inward as deep as he could until he could penetrate no deeper. With his tongue embedded in the rhinoceros's rectum, he formed as strong a suction with his lips around the large ring and Frenched his boyfriend's ass as hard as he possibly could. He rubbed his tongue up and down, sliding it along the tight sphincter muscles to imbue the strongest taste he could on his penetrating organ. The flavor was even more pronounced and an intense sexual ardor exploded in his crotch, his ass radiating fervent heat as he approached a second climax. He sucked and sucked away at the ass trapping his muzzle, the taste getting more and more marked as it continued to slides in and out along the bumps and ridges of the wrinkled surface.

"Mm, God that feels good."

Demi inadvertently tickled Daddy's tailhole and the rhino clenched his asshole around the lengthy organ violating his backside and Demi's tongue was squeezed tightly between the anal muscles. At the same time, the rhino clenched his butt cheeks and squeezed the fotter's maw, a feeling of large, bumpy, stone-hard boulders holding it in place so he couldn't move or do anything but lie there and let the smell and taste of the fragrant ass propel his climax forward. After a few seconds, Daddy relaxed and without skipping a beat, Demi continued to French the musky rosebud, his peak close and hoping to coax it out soon. The sensation was no less effective on Daddy's ass and he clenched up again, trapping his tongue for a few seconds before letting go. The act was a thrill for Demi and an enjoyable one for Daddy, whose cock remained hard, though not fully erect. While he knew his boyfriend was close to cumming, he wasn't ready to loose another load, so he let the fotter tongue his back entrance while he continued to show-off and even kiss his own muscles.

Demi continued to shuffle restlessly under his mate, his balls close to exploding in a second powerful climax. For Demi, the fact that the rhino's butt musk was solely responsible for driving him to orgasm meant an even more stimulating release and one he was anxious to experience. His goal close at hand, Demi rubbed every inch of his sensitive tongue along the surface of the fetid orifice and sucked on the musky stink-hole with such alacrity his stomach was aflutter like a tornado of butterflies. Daddy clenched a few more times and Demi simply continued to tongue him after he relaxed, the smell of the sweaty crack clinging to his nose and sweat continuing to stain his face. Demi tried to coax as much of the odoriferous pheromones into his lungs as he could, huffing rhino ass ardently as he felt his balls close to unloading.

Within a short minute or two, Demi felt the effects of the stench-laden pachyderm ass finally bring his sexual release to fruition. Before long, he felt his balls tighten up again and his cock hole engorge with male fotter fluids. In an instant, he felt his penis erupt with seminal fluid that shot out hard in a powerful burst that splattered somewhere unknown to him. Daddy, though, paused his flexing as a long, chunky string of ejaculate fired straight up at him, landing on his crotch. With a mischievous grin, he clenched his asshole again, trapping Demi's tongue within and clenched his round, powerful, muscular gluts together, holding his muzzle in place around the musky hole while Demi let off another pressurized shot of fotter sperm. He fired again and again, the testicular juices staining Daddy's lap while the stench and aromatic flavor of the rhino's ass kept his climactic state at the most erogenous level. During his ejections, Demi lifted his legs in the air to try to reduce the immeasurable sensation in his groin, kicking the air lightly as he continued to let loose wave after wave of his spunk.

"Damn, Demi. I didn't know you huffin' and lickin' my asshole could get you off that hard. My crotch is covered in your cum."

Demi would've smiled at the thought if he could move his lips, but with Daddy trapping his tongue and muzzle in place, he just sniffed away at the backside odor as his second orgasm began to ebb away. Smaller streams of jizz ejected from his urethra, landing on his belly until the last of it oozed down his glans, his balls empty and only a small blotch of sperm remained trapped within his dick, though he was unable to coax it out. He just lay there panting heavily through his nose, the stink just as strong and potent as ever.

"Very good job, Demi. I think my asshole actually might've gotten a little bit cleaner." Demi wanted to shake his head, knowing full well the wrinkled ring was no where near any cleaner now than it was before. "But I think you can still do better, so keep workin' at it."

Demi groaned and his cock twitched, unsure if his face could remain plastered to the fetid rear end without building up to another orgasm. However, he had no choice but to comply, so he continued to lick away, the odor remaining powerful as well as the taste. He retracted his tongue, his muzzle afire with spicy rhino musk tingling the back of his throat. He tried to lick more than just the anus, getting the sides of where he could reach. Daddy even relieved some of his weight so that Demi could move his face and get a little more of the sweat that remained. However, after some time, merely remaining motionless was enough to keep Daddy's butt from glistening with perspiration and there was little more Demi could do to dry it up. He'd be content to remain where he was, sniffing rhinoceros ass stench all day and staring at those ripped, bulbous ass cheeks, but he was starting to get hungry and he knew Daddy would be as well, especially after such a strenuous workout.

Demi couldn't tell how long Daddy sat on his face as it was quite hard to determine the passage of time when you're just staring at and huffing pachyderm butt, but eventually the giant stood up and the loss of weight allowed Demi to breathe regularly again. He had to rub his jaw which had become fairly sore after being kept ajar the entire time, but the more disheartening thing to the fotter was that the air smelled fresher now, or at the least less musky and immediately he missed the unimpeded stench of his boyfriend's rump.

"All right, I think that's enough for now," Big Daddy said as he helped Demi into a sitting position.

"Ugh. Thank you, Daddy, for letting me act as your towel," Demi said in a weak voice, realizing it had only been about a half an hour since Daddy parked his rear on the fotter's muzzle.

"You kidding? I don't think any cloth could do as good a job as cleaning up my immense sweat as you could." The rhino gave his boyfriend a kiss on the lips, which Demi returned. "Ugh, seriously though. You entire face smells like my ass," he teased. Demi chuckled. "Well, come on. I could eat. Let's grab a bite and lie down for a bit." Demi nodded and the couple began to walk out of the gym. "Then later, we can finish the rest of the workout."
