Muscle Material

Fahr and Kahl are (C) Zhu

Fahr smiled as he held up result of several days of hard work, the last piece finally finished in his hands. The muscular, golden-furred lion inspected every seam and stitch on the garment, using a critical eye to ensure everything was up to his exacting standards. Just as the feline used the gym to sculpt his body into a toned, limber machine, he used his sewing machine and small studio space in the apartment he shared with his boyfriend to sculpt clothes.

The fabric glimmered in the light as he drew a finger down the side of the outfit. "Perfect," he thought, tail whipping behind him with excitement. The only thing left to do was to try everything on and surprise Kahl, his golden retriever boyfriend, who was currently off at school. The canine studied hard to earn his degree in nutrition and gastronomy, but it also meant they didn't get to spend as much time together as Fahr would like. This weekend would be different.

The fabric caught the lion's eye again. He rubbed his deep, rich red mane with a paw as he set the garment back down and picked at a few stitches, repairing them where they went slightly askew. He hunched over his work desk, naked from the hips up as he applied the finishing touches. Nothing was going to spoil tonight.

The material itself was strange. Fahr ordered lots of different fabrics online, but he hadn't remembered where this particular batch came from. It was smooth to the touch, like silk, but much stronger and surprisingly stretchy. It stitched easily, without bunching up, and even cutting it was a breeze compared to the trickier fabrics he'd worked with in the past. Too bad there was only enough for one small outfit, but he was sure Kahl would like it.

The lion worked quickly and delicately, surprising for such a large male. His arms were buff, rich with power, as were his legs. He was particularly proud of his perfectly toned chest and abs, especially the thick ruff of red fur sprouting from his sternum and running down the center of his belly, into the thick hair around his meaty package, currently wrapped up in a pair of tight blue jeans. His long tail swayed behind him as he worked, tuft flicking to and for as he concentrated.

Fahr purred to himself as he finished up and put away his tools, but stopped abruptly when he glanced at the clock. It was already 4:30 - Kahl would be home any moment.

The lion grabbed his completed garment and rushed into the bedroom, undoing the fly on his jeans as he went. He'd just managed to get the pants off and was working his tight underwear down his beefy thighs when he heard the door open.

"Fahr? I'm home!"

"Be right out!" the lion called, lunging towards the door and locking it. No sense ruining the surprise by having his boyfriend walk in on him now.

"I picked up take-out on the way home!" the golden retriever called. "Hope you're hungry!"

The lion grunted as he pulled the fabric over his torso, then the matching bottom. He turned side to side in front of the full-length mirror on the back of the door, checking the fit. A little loose here and there, but overall, pretty good. Too bad he didn't have time to clean up the stray hem he noticed, but it was too late now.

"Sounds great!" he called out, smoothing his heavy paws down his muscular chest, flattening the material somewhat over the chest fur sprouting between his pecs.

Kahl stood in the living room, where they often ate their meals on the couch. The small dining space served as Fahr's studio and the bedroom held most of Kahl's books, leaving the living room as the only place they could comfortably sit together for meals. The canine's back was to the hallway when Fahr emerged from the room clad in his new, handmade clothes.

"Hello, lover," the lion said, his voice a low growl.

Kahl's tail wagged furiously as he turned around, but the retriever's muzzle dropped open in shock when he saw what his boyfriend wore.

The lion leaned an arm against the door jam of the hallway entrance, one leg bent coquettishly at the knee. A sparkling white top flowed down his broad chest and belly, a girlish, feminine top that accentuated the lion's hard and fat pecs. His nipples pressed outwards, tenting the light material even through the tight bra made from the same material that wrapped around the lion's chest. Fahr purred as he watched his boyfriend's eyes drop to his hips, where his large maleness tucked into a clean pair of panties, wrapping halfway around his hip. The semi showed off the lion's size as it stretched slightly outwards, pulling the fabric away from the big feline's hips.

"Whoa..." was all the canine said as he stared, wide-eyed, at his muscular boyfriend.

"You like it?" the lion said, purring again, turning around to show off his defined rear end. The fabric hitched up under his tail and squeezed his thick rump cheeks together.

"Yeah... that fabric looks amazing on you," the retriever said, forgetting all about the food in the plastic bags on the coffee table behind him. "I mean... it's lux, right?"

"I don't even remember buying it," Fahr said, his voice husky, dropping lower as he walked into the living room, towards Kahl. "But I'm glad I did."

"I am too..."

The canine met his boyfriend halfway, leaning back and tipping his muzzle up towards the bigger male. Kahl shivered as he felt the fabric rub against his fur and closed his eyes, tongue pressing out to meet Fahr's. The lion's growls sent rumbles through him as heavy paws reached down, squeezing at the retriever's sides and hips, possessively grabbing at him.

Kahl splayed his fingers over the fabric covering Fahr's chest, feeling the hem of the bra underneath. At first he'd thought it a little strange his boyfriend liked to dress up this way, but now, he'd come to enjoy it. Seeing such a muscular hunk in such revealing clothes got his motor running in a big way. The retriever's ears went back as he closed his eyes, moaning into the lion's muzzle. He slid his paws up, over his boyfriend's shoulders, and curled his fingers into the lion's long, luxurious mane, then further back, where the mane was longest and deepest by his ears.

Fahr shuddered as his maleness throbbed inside the tight white panties. His nipples were rock hard inside the tight homemade bra as his fingers dug into Kahl's rump, tugging the smaller male in nice and close. He could feel the canine's erection through his jeans and purred all the louder.

Eventually, their kiss ended. Kahl moaned and panted, eyes half-closed as his nostrils flared, inhaling his boyfriend's musky scent.

"The food's gonna get cold," he murmured, rubbing his paws back down to the lion's pecs again.

"Who cares?"

The lion lifted the canine by the rump, and Kahl gasped as he wrapped his legs around his boyfriend's hips. Their muzzle met again as the big feline carried the canine into the bedroom, where the lights were already off.

Their makeout session resumed, with the lion on top, Kahl underneath. The golden retriever's legs spread wide around his boyfriend's hips as they pressed together, bulge to bulge; Kahl couldn't resist rubbing at the bigger male's belly and chest, feeling the ripples of muscle beneath the smooth, feminine clothing.

Fahr moaned hotly, his breath washing over Kahl's long muzzle. The feline's paws gripped at his boyfriend's body, squeezing him possessively around the belly before dropping to the canine's pants. Kahl let him pull them off. His own paws were too busy rubbing against Fahr's pecs to worry about it.

The lion arched his back, pushing his chest into Kahl's fingers as he dragged the dog's jeans off, then his underwear. They separated for only a moment to get the retriever's shirt off before pressing back together, tighter and closer than before.

"Damn... you feel so huge," Kahl gasped, loving the weight of his big lion's hips pushing him down into the mattress. "I mean, you must've got swole at the gym today or something."

The lion grunted, pushing his muzzle into the thick fur around Kahl's neck. "Didn't go to the gym today," he muttered. His teeth opened to nip at Kahl's neck and the canine seized up, then groaned and shoved his hips restlessly up against his boyfriend's bulge.

"Whatever you're doing, keep it up," Kahl gasped, both paws taking a fat pec in each paw and squeezing hard. His fingers could wrap all the way around the shelf-like muscles, with his thumbs positioned squarely around the bulge of the nipple in the center. They flexed into his palms and he let out an urgent moan. "Fuck, these are huge..."

The lion didn't respond as he leaned down, switching to the other side of his boyfriend's neck. Kahl's fingers shifted lower, over the lion's belly, tracing the contours of his abs through the shimmering white fabric. The glossy feel accentuated how deep cut Fahr's abs were and Kahl moaned again. He struggled to reach lower, but managed to get a few fingers around the thickness stretching the smooth white panties; the canine's tongue flopped out when he felt the girth throb into his palm, which came away wet.

"Holy shit... Fahr..."

The lion's backside rippled and stretched as he crouched over Kahl. The big feline ignored what his boyfriend said, focusing on teasing and licking and nipping the canine's sensitive neck, occasionally working his way over to the muzzle for a kiss.

Kahl lifted his paws back up as the heavy lion's hips thrust down needfully. The canine's fingers traced the lion's pecs and his eyes widened. They were definitely bigger. Not just from a week ago or a day ago, but from a few minutes ago.

"Fahr... Fahr, you're... so big," he gasped, trying to form words as the relentless feline's muzzle pressed into the side of his neck, then shifted up to his ear, huffing and snuffling around the inside. Kahl's legs kicked helplessly, automatically, as the teasing set his teeth on edge and his cock on fire.

The lion's purrs changed to rough, deep growls. His paws grabbed Kahl's wrists and pulled them up, past his head, up against the headboard in front of them. The canine's eyes widened as his nostrils flared. Fahr's scent was so strong... filling his nostrils, invading his brain... the lion's eyes glowed yellow in the darkness as the big male leaned back, lips spreading in a smirk.

"Can't get enough of me, huh?" the feline said. His voice sounded lower, rough than normal, and his shoulders blocked out the windows, stopping any outside light from entering the darkened room. Kahl stared, moaning, shifting his hips, trying to speak but slammed by too much sensory overload to managed it.

Fahr lifted his arms as his hips pressed forward and down, grinding his bulging white panties against his boyfriend's belly, pinning the canine to the bed as he showed off. Kahl always liked it when the lion flexed for him, putting on a show. The golden retriever's eyes widened as he watched the lion's arms bulge outwards, spreading the pelt, stretching it. Fahr's pecs pressed outwards, pushing and stretching the fabric just as much. His fat nipples poked outwards, wrapped by the stretchy fabric, as the strap of his bra strained to contain his growing chest.

"Fahr! You're... you're growing!" the canine finally managed to gasp.

The lion grinned and flexed his biceps, then brought his arms around in a circle, making his pecs bounce.

"It's all that good food you're feeding me," the feline purred.

"No, I mean... you're... ooonnfff... oh, fuck..."

Another blast of pungent musk flattened the canine into the mattress. He gasped, tongue out, panting, watching, arms still laying limply over his head where Fahl placed them earlier. The lion's shoulders swelled, swallowing up his neck, the changes accelerating. More red hair sprouted from his mane as it lengthened, reaching down his chest to just above his thick nips. The big male's belly hardened as the ripped abs deepened, sharpened, going from a six-pack to a 12-pack before the disbelieving golden retriever's eyes.

"What the..."

The lion shuddered and flexed again. His clothes stretched tight around him now, outlining every single bit of power in his bulky frame. Despite the stretch, the material didn't break, didn't give, and the seams held... somehow. Even the lion's proud stalk, currently pressing out and up, pulling the waistband out from his hips, refused to tear, though dribbles of clear pre-cum rolled from the tip through the fabric.

Kahl reached out, unable to resist anymore, and dug his fingers into his boyfriend's chest. The lion's golden fur was longer and deeper than before, though his muscles were somehow even more pronounced, even in the darkness. Kahl pulled the lion down on top of him and whined as the feline's maleness shoved into his belly, fat and hard and definitely bigger than before.

The musk rolling off the lion's growing body sent seizures of pleasure through Kahl's body. He shivered and shook as he pressed himself against the lion, licking and lapping over the huge feline's chest, lips spreading around each of Fahl's nipples in turn, wetting down the fabric surrounding them with his tongue. The lion's eager rumbles encouraged Kahl on as he moaned right back.

And still Fahr grew bigger, stronger, more massive. The bed creaked beneath them as the lion's hips thrust slow and steady, grinding into Kahl's belly, rocking the canine back and forth. Huge paws groped at the retriever's sides and hips, digging massive fingers into his pelt until he was limp like putty in the lion's paws.

Still the fabric didn't break. Fahr was easily a foot taller than before, but at least that much across the shoulders, probably more. His belly felt like a rippling mountain range of muscle, all peaks and valleys. Kahl couldn't understand what was happening, but the canine's scent-loaded brain didn't much care. He pressed his nose into the lion's mane, under his chin, and inhaled as though he were trying to breathe the whole lion in.

"Oh fuck..."

The canine whimpered as he fell back, cock jerking against the lion's heavy sac, spurting a stream of cum into the white fabric wrapped around the feline's balls. Kahl came hard, an instant orgasm sending shivers from his ears to his toes. The musk made his eyes roll back in his head as he arched his body into his boyfriend's thrusting hips, groaning needily. His fingers reached out desperately, curling into the long pelt, pulling him down, wanting his weight on top of him, squeezing and enveloping him, taking him.

The lion's blazing eyes opened wide as he pumped harder. His cock felt amazing. His body felt amazing. His boyfriend felt amazing. He loved how squirmy Kahl felt underneath him, so small and lithe compared to his own massive frame. His biceps swelled and his thighs expanded as the bed creaked again beneath them.

There was no holding back now. Fahr had to have this canine's tight rump. Rough paws flipped the retriever over onto his belly as he leaned back for a moment. His huge maleness pressed outwards lewdly, curling at the middle, with the waistband pulling the tip slightly back towards the lion's belly. He was easily over a foot long now and swelling fast. Fahr wrapped his paws around Kahl's hips and pulled the whining canine up to meet his meat. He ground his hips down, rubbing his fabric-encased shaft between the retriever's cheeks, under his tail. The white fabric still showed no signs of breaking as the lion's figure grew even more rapidly.

Fahr growled as he pulled the waistband down. His maleness flopped out, smacking between Kahl's cheeks. The canine wriggled and pushed back eagerly, paws pressing flat to the headboard to stabilize himself. Fahr grunted and flexed all over as he gripped his shaft at the base with one paw and squeezed. Thick streams of pre-cum splattered under his boyfriend's tail, painting the yellow fur with stripes of seed.

There was no foreplay now. Fahr pressed forward, grinding his fat tip into the canine's hole. Kahl keened, long and high-pitched, as the thickness spread him open. His toes curled and uncurled, his knees bent, kicking against the bed, as the huge maleness pressed inside, relentless and powerful, overwhelming the dog's aching ring.

Fahr surged forward. His shaft throbbed, flexed deep, popping into the retriever's rump. Kahl cried out as the huge lion leaned over, chest to the dog's backside, shoving him down into the mattress. The lion's body flexed, pecs rubbing against the canine through the feminine top. Kahl wriggled and squirmed, gasping, moaning, even squealing as the lion's hips pushed down, filling him with inch after inch of lion-stalk.

Huge arms pushed underneath Kahl, then wrapped around him entirely, encasing his chest and arms and belly. The lion's hips pumped in, driving deep, hard and fast now. The canine's head twitched, his eyes rolled back in his skull, his nostrils flared as those huge biceps squeezed him. The lion's pecs ground into his shoulders, pressed against his neck, then surrounded the back of his head as the big feline got bigger. And bigger. And bigger.

Kahl cried out again, a second orgasm ripping through him. His hips jerked frantically as he struggled to push back into the lion's thrusts, wanting it all, needing it all, lusting for the scent of his boyfriend, that masculine smell of power and sweat. Red fur draped around his face, covering his eyes, as Fahr's hair continued to grow. Even the hair in the lion's armpits lengthened to ridiculous proportions as his body filled out.

The big feline grunted and drove his maleness deep. Primal need overcame him as he felt his squirming boyfriend moaning beneath him. The urge to rut, to breed, to dominate overcame him as his shaft thudded heavily into the canine. It was nearly as thick as Kahl's thigh and showed no signs of stopping as the white fabric stretched farther and farther around the feline's growing muscles.

Fahr got both paws around Kahl's hips, fingers interlocking over the canine's smooth belly. The idea he was so much larger now barely registered as he hauled his boyfriend back and down, forcing his cock deep and true. He leaned back, kneeling, thrusting up into the air as Kahl followed suit, shoulders bouncing back against the lion's immense chest, pinging off the bigger male's pecs.

The bed cracked. All four legs gave out at once, dropping them a foot or so onto the floor. Kahl wailed and leaned back, arms reaching to wrap around his boyfriend's neck, hands disappearing into the lion's oversized mane and shoulders. The canine's belly distended with the shape of the lion's arousal as the feline panted hard, head over the dog's shoulder, watching the ripples in his stomach.

Fahr's teeth came out as he felt his orgasm near. His chest grew harder, larger, pecs immense and full, swollen and crossed with veins. His nipples poked into Kahl's backside, each as fat as a shot glass on the ends of the slabs of meat beneath. His powerful legs compressed the mattress beneath them as he forced his cock deeper, holding himself as the canine spasmed around him, using his paws to keep himself hilted, as the pleasure and pressure grew and grew and grew and...

Kahl's howl echoed in Fahr's ears. The lion's cock shot off, huge loads of lion-seed erupting inside the canine's distended stomach. The lion wrapped both arms around the male, clutching him tight, pulling him into his chest and stomach, flexing against him as his shaft rhythmically pumped inside, flexing and lurching.

Kahl came for the third time himself, shooting so hard his small, by comparison, load splattered against the wall above the headboard. His arms stretched back, tugging and pulling on Fahr's red mane as he howled and bucked and twitched in his boyfriend's oversized biceps.

The golden retriever shuddered. He could feel the log inside him, plugging him up, still pulsing, still emptying into his bloated stomach. The dog panted hard, tongue out, as his head rested between his boyfriend's massively engorged pecs, which were so large they essentially had cleavage. The bra somehow remained strapped around them, though pulled taut like a wire.

The lion's breathing gradually calmed as he squeezed the canine close, hips not moving. His warm breath washed across Kahl's muzzle as the canine shuddered, unable to relax with such a big meat inside him.

The feline growled suddenly and leaned forward, shoving Kahl into the mattress. The canine gasped and jerked as he felt his boyfriend's huge nuts slap against the back of his thighs.

"Again!" the lion growled. "Again!"

That's when he felt the massive length inside him swell again, and the huge pecs grind down into his shoulders, burying him into the mattress. Kahl whimpered as he came yet again on the first stroke of the lion's renewed thrusting.

"Again!" he heard himself moaning. "Again!"

"So the shipment arrived?"

"Yes."

"And the results?"

"Above average."

"Excellent. Send him another batch next week. Let's see if they'll both get dressed up..."

The tiger leaned back in his tall office chair, fingertips pressed together, a devious smile on his face.

"After all, Danathco always delivers..."

The end
