A Hound's Heat

Chapter 2

A few weeks had passed since Tachi obtained his new Houndoom. There were no other Pokémon that could stand up against the mighty fire dog. What's more, Gunther had seemed to only increase in size every day, getting a bit bulkier, heavier, and taller. The training that the water wolf was putting him through was paying off tremendously. Everything that Tachi made Gunther do put an inch or so of size and a few pounds on his body. He was now a head over the wolf and at least a hundred pounds heavier.

The gigantic, lumbering form had to bend down to fit through doorways and move sideways through doors if they weren't a set of double doors. Gunther had gotten so obsessed with getting larger and stronger that he had pushed everything out of his mind. His past was gone. As far as he knew, he was always a Houndoom and he wanted to get better for Tachi. The wolf had given him everything he ever wanted and more.

There was a new development that began to emerge in Gunther, however. Despite eating a tremendous amount of food and meat, he wasn't able to be completely satisfied. On more than one occasion, when Tachi pleasured Gunther, he could feel certain orifices spreading rather easily and tugging whenever he inserted a body part. Whenever that would happen, Gunther would spasm and tense, his muscled body rippling and almost unable to control himself from stuffing the wolf in deeper. He kept his mind, though, but Tachi knew he had to act fast, otherwise Gunther wouldn't keep it for much longer.

Figuring that he would simply introduce Gunther to his new predatory nature, Tachi looked around for him. The Houndoom was steadily pumping weights in the gym and that's where the wolf found him. Tachi entered, watching and perking his ears as Gunther sprawled on his bench, steadily pumping what seemed like a ton of weight. Those black-furred muscles rippled and pulsed, veins steadily trailing over those limbs and pecs. Sweat dripped onto the floor from his powerful body, musk filling the room that easily overtook everything else.

The gigantic pecs wobbled and tensed with each forceful push, brushing against the broad chin of the Houndoom as he exercised. Tachi brought himself closer to watch those huge, red mounds of flesh and fur bounce and bulge with strength and power, shining in the light from the dampness they had. The huge, black nipples were pointing down from the sheer size of those mountains, shining and dripping with brine as well. The wolf drew himself closer and watched those thighs tense and flare, trying to keep himself up.

Between those thighs, the massive package was kept only by a large, red speedo, audibly straining it while the blood flowed through that body. Those abs were rippling, but also let a thick, gurgling growl go right after the barbell hit the clasps of the bench. He slowly sat up and growled, reaching down to rub his big paw over the huge chest mounds, thumbing a nipple while he let a rumbling, ground-shaking growl as he did. However, he noticed someone staring, blinking and seeing Tachi.

"Oh, hey master! I didn't see you there," Gunther grunted with a grin.

Tachi immediately moved forward, uncaring that the other was dripping with sweat, and gripped his huge arms around those massive pecs, growling and squeezing them while he lifted his head, trailing a lick over that chin. The heat was incredible, almost feeling like he was engulfed in a sauna as those wide tree-like arms engulfed him into the huge muscle tits that his face was pressed between. The musk was all he could smell now, buried into that flesh and fur while he nuzzled deeply into Gunther's cleavage.

Gunther growled deeply to his trainer, nuzzling through that blond hair while he held him tight, leaning down to kiss against that muzzle, taking Tachi deeply while his large lower lip caressed against Tachi's chin. Their lip-lock lasted a few minutes, making out and thrusting fat tongues together while saliva trailed down their chins. Tachi was soon covered with that musk and sweat, though he didn't seem to mind, and grinded himself deeply against his Houndoom while their massive packages meshed.

The two giant baskets smacked loudly together while the wolf humped, making Gunther groan out a heavy rumble, speedos creaking against each other. Gunther was leaning forward, letting his tremendous weight weigh down over the wolf, almost pushing him down while the strains grew to tears. Saliva meshed, coating the wolf's face while he was pressed back, soon pinned down by Gunther's huge body, feeling those arms hold him tighter, almost hiding him completely with the huge fire dog atop.

The heat only increased around him as the passion and arousal grew with the insistent Houndoom. A deep, rumbling growl left the broad chest of the canine Pokémon while those paws gripped along Tachi's broad pecs. The black paws easily engulfed those limbs, squeezing and working the bulging biceps. He kissed and slurped into the wolf's maw, broad tongue filling and bulging those cheeks out while saliva continued dribbling down.

Tachi's fat cock throbbed in his speedo, causing it to strain further against Gunther's, louder rips being heard while he rolled his hips. Black flesh was showing through the slits of the failing material, rolling himself against that body a bit harder, grinding his paws into the massive pec mounds that rose and fell above him. His fingers sank into that flesh, gripping into the tits and wobbling them about while he rubbed and kneaded, trailing to those nipples and squeezing firmly.

Gunther let out a loud, thunderous groan of pleasure as those sensitive handles were gripped, throbbing fatter and harder beneath those fingers, spreading them easily while they grew as well. Tachi trailed his thumbs over the tips, shoving them along the middle and pressed them inward, noticing that they spread easily enough, but gasped as he felt the squeeze and tug that followed a flex of those mounds.

It was that instant that Gunther's red speedo broke free, popping off to the side and smacking to the floor as the gigantic, throbbing dog meat slapped along Tachi's front, pinning him down further as he grinded downward. The weight of the huge meat and powerful body of his Pokemon knocked the wind out of the wolf, but Tachi quickly drew his thumbs out and pushed against the chest muscles slightly.

"Nnnh... wait, Gunther..." the wolf panted, soon breaking the kiss as they breathed hotly against each other's faces. The fire dog seemed somewhat confused, but did as he was told, sitting up somewhat and looking down as his heavy dick throbbed over Tachi's big muscle gut, dribbling a pint of precum that landed messily over Tachi.

"Is everything okay, sir?" the huge dog asked, panting and lapping over the wolf's face with his sloppy tongue.

"Yeah, of course. I want to make you feel even better, though, and let you have your fill," Tachi murmured with a smirk.

Gunther only looked more confused.

"You found a way to make me less hungry?"

Tachi smirked and brought himself up from beneath his massive partner, looking around and humming.

Nearby, a rather massive lion was pumping up a barbell similar to how Gunther was previously. He was nowhere near as big, but it was obvious that the feline had been looking toward the two as they stimulated each other. His package was bulging with the musk that was flooding around, trying to ignore it, but failing. The lion seemed to be about seven feet tall, a few hundred pounds, and now his cock was almost pushing down his leg hole while he lied back.

After a few more minutes, he let the bar latch back to the bench, slowly sitting up, and blinked when he realized he was being watched. Tachi smirked at the recognition, using his finger to motion the feline to them. A heavy swallow came from the feline's throat, but he slowly walked forward as he was motioned. Tachi was the owner of the gym, after all. Approaching closer, the lion stood there, unsure of what to do.

Gunther blinked and looked to the lion, then back at Tachi with a tilt of his head. He wasn't sure what was going on until the wolf drew his paw down and rubbed along the slit of his fat, throbbing cockhead. The precum continued to dribble, causing the big fire dog to moan and arch, not knowing that his slit had spread as if trying to catch the fingers of his master. That cock throbbed a bit harder, almost seeming to lengthen an inch in its pulsing need.

It was that instant that Tachi reached up, gripping the back of the lion's head, and drew him down with a powerful tug. The lion gasped, having no time to react to the wolf's powerful grip, and soon felt a tight, hot maw engulfing his face--except it wasn't a maw. The huge, heated cock of the Houndoom had spread at the tip, engulfing the lion's muzzle and face with a simple shove! Tachi watched as the feline's head easily slipped in, that cock immediately clenching and pulling a few more inches.

The great Houndoom was caught off guard, giving a loud, snarling roar as he felt the pleasure running through his body like electricity. He almost fell back, but instead pressed forward and shoved himself against Tachi, gripping his huge arms around him again and grinded the tip, and the lion, against the wolf's front to push him in deeper. This led to roaring again, the huge dick rippling and tugging in his shoulders with a thick, heavy "shclorp".

Tachi gasped as he was drawn to the massive front of his Houndoom, grinning broadly as he squirmed and tensed, trying to peer through thin eyes at what was happening. Whenever he saw, those red eyes widened, seeing the torso of the lion embedded into his cock. He paused for a moment, staring in bewilderment before a flex of that monstrous member caused another few inches to slide into the hungry flesh. Gunther let another spasm go, gripping Tachi again and howled.

"T-Tachi! W-what's... rrrnngh... going on!?" he roared out as he shoved himself against Tachi, grinding forward while his cock tensed, rippling and bulging visibly with every swallow it took. Each flex drew the lion in deeper, making the inner walls slurp and tug, the body of the squirming feline easily slipping further as precum dribbled around him.

"Mmm, just let it happen, Gunther. I know what you've been wanting, even if you didn't," Tachi stated plainly, stroking along his huge pecs while he watched that cock work, rippling and sucking. Thick, wet suction sounds continued to ring through the gym while the lion was pulled up to his waist, kicking a bit more to try to stave his descent, but it was no use. Gunther was enjoying it too much.

Gathering a bit of courage, Gunther reached down, gripping the lion's ankles with his great paw, pressing him forward and deeper into his cock. After gaining a bit of his composure, he moaned louder, arching and rolling his hips more slowly as if beginning to thoroughly enjoy the sensation of a squirming meal being sent down toward his most masculine area. The lion's form visibly bulged out that dick as it pulled him down, veins throbbing along the length as those balls gurgled audibly in hunger.

The fire dog rubbed over his huge cock, breathing heavily while the lion slipped up to his ankles. That paw pushed down those feet, letting them disappear into that slit and down his great, hungry pillar of meat. Gunther leaned back, letting his cock stick up in the air as gravity assisted the constant peristalsis of the swallowing cock, watching in fascination and pleasure as the meal slid deeper, toward his huge nuts.

Tachi watched in delight while he rested against his massive Houndoom, reaching out to rub against the throbbing dick while the figure beneath that flesh began filling that sac below. Those huge balls grew with the big bumps and hills, molding with the shape of the lion while he entered them, feeding them more and more size from the collection in his cock. After a few more moments, the lion slipped completely in with a heavy, gurgling splash into those balls.

Gunther stared, panting and wide-eyed at his massive, squirming testicles. He reached down, rubbing them and giving a loud snarl of pleasure as the lion tried pushing out, but there was nothing he could do. He was being moved about by the strong paw of the Houndoom while a curious expression turned into a fiery grin, growling and gripping a bit more. Bubbling, not unlike lava, could be heard in that huge sac as it churned.

"W-wow... I didn't know it could... do that..." the fire dog panted while he stroked his sac, feeling the gurgling continuing, the firm bulges of the lion's form slacking in movement.

"Yep, you've been trying to pull me in, you know. You'll be truly sated, now," the wolf stated in reply, smirking up at him.

The gurgling continued noisily through the gym. The huge balls worked over the lion within, melting him over, getting him to smooth out and slosh inside. Steadily digesting, precum began to splatter from Gunther's cock once more as the two huge balls evened out, moving his big fingers over it to feel that there was nothing left of the lion. There were no solid bulges, only thick, heavy Houndoom cum waiting to be fired out.

"I don't feel... hungry anymore," Gunther murmured, grinning brighter, seeming happier than he had been previously.

"Well, I'd hope not. You have more hunger to sate around your body now. All of that strength and power have to be fueled somewhere," Tachi stated with a smirk, looking up at Gunther.

It didn't take long for the dog to press down once more onto Tachi, taking him into a deep, passionate kiss that sealed their lips together, thrusting tongue and saliva along each other's maws. Gunther's cock was throbbing harder than ever now, grinding against the wolf's front as he was pinned down. Precum dribbled harder, gushing over and coating Tachi in a thick layer of hot, heavy liquid that smelled of the lion, but was quickly being overtaken by the Houndoom's scent.

Tachi couldn't resist as he was pressed down, grinded against by that huge cock and the powerful body hanging over him. His arms were pinned by the great paws of his massive fire dog, giving out a loud groan as that cock pressed against his face. He felt it shoving against him, splattering over his muzzle, causing him to sputter and pant. He arched, unsure of what Gunther had in mind, but he gave a louder groan as he was pressed down further.

"Mmmnh... I could eat you too like this," Gunther growled, a smirk coming over his face.

Tachi's eyes widened as he saw the slit spread in front of his face.

"W-wait, wait Gunther..." Tachi stated, almost about to wriggle from beneath.

A deep, rumbling chuckle left the Houndoom's muzzle while he grinded again, shoving that slit against the wolf's muzzle, engulfing it. Tachi gave a spasm and tried to pull back, whimpering and pushing at it, but it was no use. There was no way he could dislodge himself from it. He squirmed and kicked, trying to pull away as he felt the tug up to his face, seeing nothing but huge, red cock filling his vision.

"It would be so easy, sir..." the huge fire dog rumbled, smirking a bit more while he watched Tachi squirm. However, he let his cock relax with a heavy sigh, letting Tachi pull from the hungry slit. "That's not how you're gonna go down, though," he snickered.

Tachi stared at the huge Houndoom, shuddering and grunting, gripping around that cock slowly and began to stroke it again.

"I want more, though," Gunther commanded, growling with a broader grin while he drew his hips back and then grinded forward again. "Otherwise I'll take you now."

"I'll get you more. I have a trainer to face today. You can devour him and his Pokémon if you want," Tachi murmured, panting and pumping that cock again.

"I like the sound of that. I need more, master," Gunther replied, groaning deeper as his cock throbbed, gushing another gout of precum. It throbbed, pulsing harder as the veins pushed to the surface along that dick, gaining more size while the pulsing was audible to the wolf beneath, but it seemed to flare and swell wider. It bulged and throbbed, widening over the wolf's form while he was grinded down into the floor of the gym.

Tachi could only nod and moan while he gripped around the tremendous pillar of meat grinding into him and along his body, coating him with more and more precum while he kneaded against it. It was half the size of his body and only seemed to lengthen in mere moments while that sac gurgled loudly behind Gunther, throbbing louder and heavier while the canine's arousal grew with it.

Gunther's growls grew louder, reaching down and pinning the wolf's arms down again, this time more tightly. He squeezed them while he rolled himself back and forth, letting the bottom-side of his shaft get stimulated by the wolf's muscular body, curls of smoke rising from his nostrils as his hips jerked and pumped like pistons to a mighty steam locomotive. Every thrust sent another splatter of hot, steaming precum over the wolf and the floor.

That sac sloshed and gurgled louder, starting to pull up toward that waist. Gunther snarled and slammed himself harder, now focusing on his own pleasure rather than caring about the wolf's safety. He felt his orgasm approaching, causing his huge, sweaty body to tense and ripple, muscles flaring all over. Arms and legs spread while he rolled his eyes back, humping harder while he gripped the wolf's arms, his groans growing into growls.

Tachi could do nothing but brace himself. His fur was thoroughly coated and matted down by all of that sticky liquid, knowing that Gunther was about to climax. He tried to move his arms, but they were easily pinned down by his powerful Pokémon. He grinded upward, sliding his own cock against that huge, slapping sac that was steadily moving over him, precum gushing from his own big, black wolf cock as it was pinned to his belly.

It wasn't much longer until Gunther froze in his thrusts. He snarled, grinding down over Tachi while the bottom-side of that cock flared up, bulging bigger and wider until it was followed by a bellowing roar from the fire dog. A plume of fire erupted from his maw while white spunk did the same from his cock. Tens of gallons of cum exploded, firing over Tachi and covering him in white while those balls surged, gushing and tensing to unleash it all.

The gym was quickly flooded, cum even firing against the far wall and leaving a loud, splattering smack to sound through the gym. It was drowned out by the roar of the powerful Houndoom, however, as he thrust and gushed over his trainer, hiding him beneath the blanket of white. It piled over him, gushing and steaming, almost looking like white lava. The wolf, being of watery descent, could easily breathe even beneath the deepest and thickest of liquids, but he was still thoroughly pinned by his companion.

It lasted for what seemed like an hour. The gym was thoroughly coated in white as the huge dog came down from his orgasm, moaning and sliding from Tachi's coated body, pulling him up in the process. The wolf was dazed, dripping all over with white as he was licked over by the thick, powerful tongue of his Houndoom. The wolf gained his composure once more, blinking and then grunting as the thick, salivating tongue draped over him and cleaned him.

After the white was replaced with saliva, he was held to the powerful chest of his Pokemon, squeezed and kneaded by the powerful muscles as those arms engulfed him. Tachi nestled close, rumbling in delight as he nuzzled against his Houndoom's chin.

"The trainer should be here soon. Are you ready?" Tachi asked with a smirk.

"More than ever before," Gunther replied.

---

A thick fox pushed through the entrance doors of the gym, moving forward and looking around. There were no other trainers around, but the 6'4" vulpine gave a grunt as he saw the large battle arena nearby. He approached it, eyes glancing from side to side while nothing was heard or seen. It was almost as if his meeting with the leader had been forgotten. With a huff, the fox placed his paws on his waist, disappointed.

It was then that the lights dimmed and overhead lights came on and shined on the arena. Whenever it came into view, the massive wolf was already standing in the far square at the other side of the field, arms crossed while he smirked. The fox was startled, almost falling back.

"So, you've decided to show up. I'm afraid that was a mistake," the wolf stated matter-of-factly.

"I've come to beat you, Gym Leader Tachi! You and your Pokémon will fall!" the fox yelled, bringing out a red and white Pokeball, clicking the button to let it swell into his paw. "Go, Manectric!"

With a heavy-handed throw, the fox launched the ball into the air to have it unlatch, red energy bursting out of it and filtering onto the ground, revealing a rather large Manectric. It was obviously powerful, sparks bouncing from his body while small laces of lighting bounced through the air around him. A deep, growling snarl came from the four-legged canine Pokémon.

Tachi raised an eyebrow at it, examining it and then looking to the thick fox. He hadn't even given the Manectric a name. A "tsk" came from his lips as he tilted his head.

"That isn't your only Pokémon, is it, boy?" the wolf asked.

The fox blinked and glared at the leader.

A sigh escaped his muzzle while he shook his head. He smirked afterward, giving a snap of his fingers as he took a step back. Behind him, the huge silhouette of the powerful fire dog was made apparent. His red eyes glowed through the shadows as Gunther moved forward, slowly moving around Tachi, and into the large box of his side of the arena.

Deep, powerful growls rumbled from the huge chest of the Houndoom, smirking down at the now gawking trainer and Manectric.

"Gunther, have at them," Tachi stated rather plainly.

It took no time at all for the fox to realize that he was in over his head. It was as if a gigantic shadow moved faster than lightning itself. Gunther appeared so suddenly in front of the Manectric that it didn't have time to react. The massive, black paw had reached down and gripped him, lifting him up and toward his pecs and maw. A thick, red tongue slid along Manectric's muzzle, causing him to squirm and snarl.

The fox sputtered, staring up at the gigantic Houndoom that was at least five times his size, seeing him almost taste his Pokémon. The Manectric squirmed, gasping and snarling, sputtering at the saliva splashing over his face while Gunther licked over him, seeming to enjoy the sparky tingles that popped over his tongue.

It didn't take much longer for Gunther to spread his lips, sliding them over the other Pokemon's muzzle and face. That maw slid forward, sinking further until the entire head of the Manectric was inside of Gunther's hungry maw. He sucked and slurped, trailing his thick tongue over the electric quadruped, growling loudly over it while he trailed his paw up, pressing against his lower half. He pushed it in further, taking a slight swallow, sending a bulge to the big dog's throat.

The other trainer was speechless. The vulpine's eyes were wide, staring in disbelief and awe at the big Houndoom taking down his powerful Manectric in one swift slurp. He saw the bulge in the fire dog's throat, watching it ripple and swell further with the squirming form of his electric type. The fox didn't know what was going on, or if it was even a battle, watching the middle of his Manectric sink into the Houndoom's lips.

A large burst of electricity erupted out, almost engulfing Gunther's body with it, but it soon stopped as it seemed to have no effect. The big fire dog scratched over his thick abdomen as he took in more of the Manectric, completely unfazed. Thick, rippling walls of that powerful neck continued moving the electric dog into the bigger fire dog. Heavy swallows sounded out while he lifted his head, letting him descend easily toward his gurgling belly.

The Manectric squirmed harder, whimpering and yelping now that he felt the hot, sticky walls kneading him and pulling him down more, letting loose another electric attack that only sent him in a few more inches. He yelped once again while his waist was being tugged, and finally the smaller canine was sliding down to his feet. The tongue bathed him in hot saliva, hearing the gurgling, hungry belly below him while he slipped down.

Now that he was fully in that maw, the last few swallows pulled him down toward the belly, pushing those abs out on Gunther's form while the Manectric slipped beneath them. The Houndoom lifted his head once more, taking one last gulp to push the last of those bulges of his meal to his belly, leaving his maw to hang open and his tongue to loll, letting a deep belch go that rumbled the walls. A lick over his lips followed before he turned his attention to the quivering fox.

Wasting no time once more, Gunther brought himself toward the fox and lumbered over him, looking down at the puny male. A chuckle escaped him while he lifted let his huge package smack over the vulpine, leaving him to fall back from the impact, leaving him to stare up at the gargantuan taint and rump of the fire dog. He still was unsure of what was going on, in a complete and disbelieving daze while those massive, wide globes of ass neared his face.

It was slow motion for him, but the fox gave a loud, muffled cry as those cheeks engulfed his face, leaving his muzzle sinking into that wide, puckered tailhole beneath that long, spaded tail. He reached up, trying to push himself away and press the Houndoom upward, but it was counterproductive. Instead, those paws sank into those wide cheeks, between them, and up into that thick hole as well. The cheeks squeezed him with a flex, drawing him up to his shoulders in a single, solid motion.

Gunther let out a pleased, rumbling moan while he arched himself backward, slipping back against the male below him while he began to squat, sinking inches of the fox into his backside rather quickly. He spread his legs, panting and reaching below his massive tire-sized balls, pressing against the squirming legs of his new prey. The pleasure was intense, sending waves of throbs through that huge fire dog cock, dribbling precum while he rolled backward.

The fox's form was half-way inside, leaving Gunther to bend forward some to feel those legs smacking against his fat, wobbling nuts. They gurgled a bit more while the trainer was consumed, each flex of those wide, bubble-like cheeks devouring more of that frame, hot passage squeezing along those thighs, and soon only the fox's feet remained outside of those mounds of fur and flesh. He was panicking, feeling every hot ripple and squeezing clench draw him deeper and deeper to where his Manectric was.

With one last arch of his hips, Gunther gave a louder snarl as those feet disappeared, sinking between the massive mounds of rump flesh, tailhole soon hidden by the large tail and those wide, rippling cheeks that bounced and smacked together once more with a heavy flex. A low groan followed as he sat back, Gunther gripping around his belly as it gurgled over its latest meals, panting hotly while the gurgling started.

The squirming slowed rather quickly as the broad abs tensed, clenching over the captives inside while the fire dog leaned back, licking his lips before lifting his head once more. His maw spread, letting another loud belch erupt from that maw, causing the insides to clench around the meals, gripping them tighter to knead and break them down even more swiftly. The bulges beneath those abs were already smoothing over, leaving thick, sloshing softness.

The ripples and pulses started moving through Gunther's body. A deep groan escaped his frame while he arched upward, his belly clenching, abs seeming to brick a bit tighter over that front. Veins pushed to the surface of his arms and pecs once more while everything began. He tensed, arching and flexing with a deep snarl, sounding through the gym while his body pulsed, arms starting to flare with inches of muscle adding onto them.

Those pecs pushed outward, rounding further and pressing along the broad chin of the Houndoom, leaving his tongue to loll over them and drool. His thighs were pressing apart with each throb, veins visibly moving over those as well while he lifted his head back and snarled. Gunther was steadily growing, adding on pounds of the meals he had just taken into his belly. His cock throbbed harder, leaving a gush of liquid to splash over the ground, spaded tail smacking the floor.

Tachi watched from afar, but seeing how Gunther's body was beginning its growth, he perked up. A smirk was drawn on the wolf's lips as he saw those powerful mounds of fur and muscle bulge and ripple, expanding before his eyes. That broad back pressed outward, simply swelling with every pulse and gurgle that erupted from that huge body. Tachi moved closer, trailing his broad paws over that expanding surface, kneading into the muscle as Gunther enjoyed his steady increase.

The Houndoom's groans only grew deeper while his muscles expanded, including his neck and shoulders. Thick pops and deep, meaty creaks moved through that body, echoing through the gym while his form expanded, gripping at his own pecs to feel them swelling and spreading his fingers while they pushed out. He panted, drooling almost mindlessly before he felt those mounds pushing outward, bulging even more, nipples fattening while his belly slacked in girth and regained its tremendous cement-block abdominals.

Tachi slipped around, looking at that gigantic cock that rose from between those widened thighs, dribbling precum while veins fed that meat with size and heat. The wolf saw the red eyes lock onto him, followed by a broadening grin from that drooling maw. Without giving Tachi a chance to react, those two big, black paws reached down, gripping around his waist and pulled him forward. The wolf didn't resist, especially now that he was engulfed by orange and black fur-covered muscle.

With his senses overloaded with everything that was Gunther, the wolf moaned and buried his face into those huge mounds and grinded his face up and down along one of the curves.

"Fuck, Gunther... you've gotten so big," Tachi groaned, being coated with a bit of sweat and even more musk.

"Master...I need more. I want you," Gunther rumbled, shaking the wolf with his voice.

Tachi grinned and nuzzled along that chest, lifting his head up and trailing his muzzle along the bigger one, taking him into a rather lustful kiss. Those lips locked once more while Gunther held him tighter, Tachi bringing his paw up and stroking against that cheek while tongues danced. Those appendages meshed and smacked together to make saliva dribble down their chins, but soon the kiss parted while they looked at each other.

"Take me then, Gunther. Use me as you wish," Tachi whispered.

As if taking that as a command, the big dog gave one more lick to Tachi's face and guided his head toward his chest. That big paw almost engulfed the entirety of the wolf's head and press that muzzle into the crevice of those huge mounds. They flexed, squeezing over the tip of the wolf's face while he saw nothing but those huge, orange mountains that were his Houndoom's chest. They moved against him and squeezed over his cheeks as he began to inch into it.

That big, black paw pressed Tachi against Gunther's cleavage, making the wolf gasp as it easily engulfed his entire head now. A flex and roll of those shoulders sent those mounds rippling and tensing over Tachi's head, drawing it deeper into that moist, musky valley. Tachi heard Gunther moaning out whenever he flexed, deep grunts of concentration coming from his throat while the wolf began to sink further.

Each tensing bulge pulled the wolf's head a bit further, followed by his shoulders while Gunther held him. He stroked over the wolf's back, but gripped him and pulled him inward, letting his massive mountains squeeze and steadily devour him. The pectoral muscles were throbbing bigger, swelling and bulging with the entering wolf. Gunther moaned a bit more, feeling his chin being pushed upward by the steady increase of mass.

Tachi slipped further and further, his own pecs being squeezed and pulled while his arms were pinned down, moaning in muffled tones inside of that torso. He squirmed, flexing to perhaps make it more exciting for Gunther, but the Houndoom easily pinned him further, stuffing him into the swelling pectoral muscles. He snarled out, gripping Tachi's legs while he shoved and arched. Those mounds rolled and wobbled, being fed even more.

Those soft, yet tensing walls were steadily pulling, every moment sending a few more inches of the wolf into the hungry torso of his huge Pokémon. Gunther arched and moaned, lifting his head to avoid his own muzzle being engulfed by his pecs, moving his paws from his master to grip at his nipples. He kneaded and twisted them, causing him to snarl louder while he flexed, swallowing Tachi up to his waist now. The wolf's cock was steadily throbbing below, dribbling precum over the huge Houndoom dick.

It only took a few more moments for nothing but the wolf's feet to be hanging out, leaving Gunther to pant and grunt. He squeezed his nubs a bit more, watching his powerful chest mounds swallowing Tachi, hiding him from the outside world with one more ripple and tug. The wolf was completely consumed by the gargantuan torso, moaning loudly and rolling his pecs around, alternatively to each other.

Tachi felt the heat seeping into his form, already lulling him into a stupor while Gunther enjoyed his top-heavy body. His heavy breathing sent his mounds to rise and fall, but soon the flexing began again, tensing harder and flaring, sending added pressure through Tachi inside. A few pops and snaps were heard, leaving Gunther to grin drunkenly while his arms started pulsing once more. Throbs signaled a new wave of growth, causing his deepening voice to moan even louder.

The wolf inside shuddered, gurgling and arching while his form softened, meshed into the walls of the pecs while they squeezed and gripped him. His consciousness was slipping away until he passed out completely, fully belonging to the powerful Houndoom. His body was squeezed harder, being worked down while his belly tensed, lines deepening while his mass increased. Everything that Tachi had been was now being added to Gunther.

Gunther gripped his pecs, snarling in bliss and lifting his head back, moaning louder as his cock throbbed harder, giving a few hard gushes while his orgasm approached once more. The gym was now empty aside from the Houndoom, fondling his pecs and watching them move about. He gripped his nipples once more, holding them like handle bars while he arched and pressed upward. Gallons of precum flooded over the floor.

A few more gurgles and creaks signaled a few hundred pounds more added from the wolf which led to a few flexes of those arms. They flared with size, bulking as sweat dripped down the gigantic, watermelon-sized biceps and down the wing-like lats of his sides. The feel of so much strength beneath his fur sent Gunther over the edge. Gallons of cum spewed from his dick, hitting the far wall and splattering against the ceiling as he roared.

The roaring continued while cum gushed and gushed, flooding the area while he spread his legs, one paw reaching around his huge, pulsing dick while the other gripped his balls, letting his new pectoral muscles engulf some of his dick, almost fully wrapping around the huge meat. He pumped and thrust, launching more and more of that white liquid along the ground and walls. It lasted for minutes, almost seeming like an hour, and finally ebbed to a constant, trickling drool.

Gunther panted, licking over the tops of his mountainous muscle tits, squeezing his nipples once more while he relaxed, leaning back some as he closed his eyes. He gave a firm smack to one of the pecs, causing it to jostle and ripple with its non-flexed softness, watching it bounce and collided to the other before coming to a slow stop. With a lick of his lips, he belched once more, rattling the walls as he signaled his victory.

"Mmnh... thank you, master. I will use you well and get even stronger," he murmured into his massive mounds, kissing over both of them.
