Seven-Day Trial

Part 3

Tachi was almost disheartened that Bobert's training week was coming to an end. He considered doing a few things that might make him a "bad slut", but at this point, he was afraid that Bobert would end the week early. The otter was undoubtedly planning a big finale--each day seemed more grand than the previous. The great wolf wasn't going to ruin it.

Despite having been shown to be a cock-loving lupine, many members of the gym still shuddered in his wide berth. The wolf was somewhat relieved that no one disrespected him, even though he noticed a few more whispers amongst the patrons whenever he moved through the gym. Tachi thought he'd be able to make it through the week without anyone trying anything, but there was one that thought he could try to claim the great wolf, too.

Tachi decided to finish up a bit of cleaning, himself, instead of calling his janitorial staff in. He was on his knees, trying to scrub down a few of the weight benches that were showing a lackluster dullness.

"Hey there, slut," the voice came from behind the wolf.

A tingle ran down the wolf's spine--the sound was unfamiliar.

"I beg your pardon?" Tachi's deep rumble had a rather angry undertone. He turned his head, having to lower his shoulder somewhat while his aquatic-colored eye pierced through the buck that had been watching since the first day. A few of the patrons had slowed their activities as the deep voice shook the room.

The glare caused the deer to shrink back slightly, his own eyes widening for the moment. However, his confidence came back as he stepped forward, even though his leg gave a slight quiver. His brown fur quivered while he raised his antlers high, trying to appear bigger than he was. If Tachi were standing, the buck would barely come up to the wolf's waist.

"I-I said, hey slut. You like dick, don't you?" the buck stated, putting his fists to his waist, standing as if he were at attention with his groin sticking out. The room went quiet.

As if hoping he had misheard the buck, the repetition made Tachi's eyes grow fiercer. The beastly wolf slowly brought one of his gigantic feet to the floor, pushing himself up to rise higher and higher until his mountainous body shadowed the brown-furred deer. The front of his form was darkened and it made his eyes glow with their angry gaze.

It was then that the buck knew he had fucked up.

The huge paw of the wolf came down and gripped the male's shirt, lifting him upward. The buck's feet were lifted at least fifteen feet off the ground as Tachi held him at eye level.

"Do you know who I am?" the wolf's voice was rumbling through the male's small, dangling form.

"Y-yes... yes! M-M-Mr. Marin! Please, I'm sorry!" the buck choked, holding to the gigantic paw that gripped his shirt so tightly.

"Not yet, you're not," Tachi glowered, "You must think that because I submit to him that I am just some filthy trash heap that anyone can get off on."

"N-n-no! No! I don't... I don't think that at all, sir! Please forgive me! I'll do anything!" the buck whined, practically shivering all over.

"I think you do. Let me see... you're Jackson, aren't you? Barry Jackson, yes..." the wolf looked over the buck's face while his piercing eyes thinned.

Hearing his name caused the buck to cringe further, almost trying to curl up in the great wolf's fist.

"If you try anything like this again, I will feed you to my rat and enjoy your squirms through his great, green gut while you gurgle away into nothing. Hell, I might even devour you, myself. I haven't had venison in a while. Would you like that?" Tachi's face had become less monstrous and more curious, if anything.

Another whine escaped the deer's throat, looking as if he were about to cry.

"P-please... no, anything but that, Mr. Marin..." Barry squeaked.

Despite appearing so monstrous and angry, the sight caused the wolf to soften a bit more. He gave a snort through his nose as a burst of steam erupted, leaving the deer to squeak and squirm slightly.

"Confidence is key, Mr. Jackson," the wolf stated, slowly lowering the quivering cervine down to the floor, who immediately collapsed as his legs gave out on him. "You almost had it. Have you ever seen Bobert wince in my presence?"

"N-no... no sir," Barry murmured, looking up at the great beast.

The massive beast lowered his leg and soon leaned over the buck, who shuddered back a bit in fear. Tachi brought his paw forward, trailing a claw along the deer's chin as he lifted Barry's head to look him in the face.

"That's where Bobert excels. He has more self-confidence than most I've met. Granted, it might be because he has such a... gigantic cock, but he has gotten to know me and has cared for me. There's love there. You can't simply go up to a stranger and expect them to kneel," Tachi explained, his eyes still glinting with a strange, fiery glow.

Barry stared up at Tachi's face, but soon looked to the side while he lowered his ears.

"W-what... what about the squirrel guy? And the mouse?" Barry murmured quietly.

The wolf felt a heat build in his cheeks, though he glared down at the deer once more.

"That was still confidence, Mr. Jackson. Neither of them faltered. And besides, they were an extension of Bobert, of sorts. Besides, I like big boys. Train harder and then we might talk," the wolf stated, giving a light tap to the deer's cheek with his trailing finger, smirking a bit, "and I can help with that if you need it. I do enjoy bucks, after all."

The buck's eyes came back up to the wolf, though a blush was creeping into his face.

"BUT," Tachi growled, his anger seeming to return at full force, "do not EVER try that again. Never assume someone wants to be treated like that. Do you understand me?"

Barry winced at the powerful voice, nodding quickly and whimpering beneath Tachi's scowls.

"Y-yes sir, never again. I'm sorry," Barry whimpered.

Tachi nodded with another snort, soon giving a light pat between the deer's antlers before rising again. He rolled his muscled, broad shoulders as a few loud pops came from his titanic back. A smile had come across his muzzle once more as the air around the wolf changed.

"Good, good. Now, get back to your workout. Everyone should get back to their workouts," Tachi called out, looking around at the staring patrons with a raised eyebrow. Even though he had been paraded around as the otter's slut, everyone quickly got back to what they were doing under the command of the powerful, beastly wolf.

That was a good warm-up. After the fiasco with the buck, the wolf decided to get to his own workout for the day. He drew himself to the larger benches he had installed, looking over the shiny metal and the blue cushions capping the tops. He grinned, setting up the proper weight for his bench press. After locking them in, the wolf settled himself on the new bench and leaned back, sighing in delight as his massive back was thoroughly supported.

While in the middle of his third set, Tachi didn't notice the otter had snuck into the gym.

Bobert snuck up to the bench and watched the bar rising and falling, near the thick pit bush that was practically hanging down from beneath his arm. A grin came over his face as he gave a few sniffs to the masculine scent of the wolf, though kept quiet as he watched the powerful pecs rising and falling above that gargantuan belly. Whenever the bar came to clank against the latches, Bobert slid up along the wolf's side to rub along the broad gut.

The touch startled the wolf, causing him to gasp and look down. He blinked and huffed while his face reddened, bringing his huge arm down and around Bobert's waist, boosting him up along the round mountain of hairy belly.

"H-hello, sir," Tachi murmured, completely different from his earlier rage.

"Hey slut. Working hard, it looks like," Bobert murmured, crawling up along that belly a bit more until he was resting atop, kneading into the thick, hairy surface.

The wolf let out a rumbling growl as his belly was rubbed, feeling the expert paws sliding through his fur and hair, shuddering somewhat while lying back on the bench. There was already a sheen of sweat on his blond, cream, and gray body, but the otter didn't seem to mind. A huge paw came down and slid along Bobert's back, arching his belly along that form while the otter grinded forward, huffing out at the feel of the round, soft orb folding against him.

"Forgot how much you liked belly, sir..." the wolf murmured with a shudder.

"Shush, slut," Bobert murmured--Tachi felt the heat of the otter's face.

A grin came along his muzzle as he pressed the otter more thoroughly along his belly, letting him feel it gurgle and slosh against him while he grinded upward. He could feel Bobert's groin steadily bulging against it, leaving the wolf to lick his lips. It was soft, but firmed up when he tensed it. There was quite a bit of flab on the surface, but beneath was a ball of muscle that could expand when contracted. The heat that it gave off left the otter groaning and grinding harder.

Tachi remained quiet as the otter enjoyed his belly, though another grind caused the wolf to let out a rumbling belch that shook Bobert and the bench beneath them. He chuckled afterward, settling and bringing his huge paws forward, sliding his thick digits along the otter's back. It slid along and then moved further over the otter's body until his arm began to engulf him, squeezing the mustelid into the folds of his great belly.

Bobert's blue eyes opened to look past the gigantic pecs and into Tachi's, grunting as he was engulfed in the great limbs of his pet. He gave another grind as he was held, lifting himself and squirming along the broad pecs, sliding through the thick fluff that the wolf had gained over the past week. Bobert grinned and lifted his head, pressing his big nose to the wolf's, looking a bit more into those eyes.

Tachi perked his ears as the other wormed his way between his pecs, and when their noses touched, his face went red. He looked to the side, not locking eyes while his cheeks heated up, though didn't remove his muzzle from the otter's.

"You're certainly a bit more... lovey today, sir," the wolf murmured with a sheepish grin over his beastly muzzle.

"Is that a problem, slut?" the otter asked, bringing his paws forward to comb through the thick beard that Tachi had grown, "Maybe I just want to enjoy the monster I've created."

Tachi gave a smirk at the statement, soon rumbling and pressing his nose a bit more firmly into the other, even trailing a kiss against his lips with his own thicker ones.

"No, sir... Just surprised me," the wolf murmured deeply in reply, closing his eyes as he felt the rubs.

Bobert pressed his lips forward, taking a deep kiss to the wolf's lips while he tilted his head, stroking through the thick chest hair and fur that bristled beneath his touch. Through the lip-lock, the otter trailed his paws to the far ends of those mountainous pecs, gripping the thick, black nipples pointing downward, squeezing and massaging while he rolled his massive package along that chest.

The grip to his fat nubs caused Tachi to tense, groaning out into the kiss as his package surged with size, his hips rising a bit while his pecs pushed up, flexing against the otter and pinning him further into his arms. He heard Bobert gasp, quickly relaxing his hold to not harm the otter, but soon held him a bit closer as he returned the kiss in full. His big, fat tongue filled the otter's mouth in their lock, tilting his head as he gave another deep, powerful rumble.

After a few more moments of tongue action, the otter pulled back with a gasp and then squirmed downward to press along that belly again, rubbing and grinding into it while he grunted.

"Got a surprise for you, slut," the otter murmured as his shorts ripped, soon bursting off easily to let his great mustelid dick slap along that gut. Precum trickled as he slid himself, his tire-sized nuts gurgling noisily behind him.

"What, it's not this, sir?" the wolf asked, smirking as he trailed his thumb along that huge cockhead, letting it tease the slit. He felt it spread and even squeeze at his digit, making Tachi blink somewhat.

Bobert snorted with a grin, pulling his hips back as he waved behind him.

Tachi perked, looking past his huge arms and the otter they held to see a broad, lumbering figure moving into the weight room. His eyes widened whenever he saw the red and cream fur in the light, seeing the massive bruin stepping forward and looking around, seemingly for someone he was missing. Still holding Bobert, Tachi sat up and grinned somewhat as their eyes connected.

Lorank's jaw went slack at the sight of the gargantuan wolf. He stomped forward and looked down at him over the monstrous pecs he had, himself. They wobbled with his steps, bouncing with their own weight before his shadow covered only some of Tachi's frame. He had never seen the wolf so huge--or anyone, for that matter. Not too often, anyway.

Tachi grinned a bit more as his face reddened, slowly standing from the bench to greet his bruin friend. It was a strange feeling, being able to look the bear in the face at eye level, but it wasn't unwelcome. He saw the wide paws of the bear slowly rise upward, pressing against the wolf's arm and chest, feeling the powerful muscle beneath while Tachi flexed. The muscle grew turgid and bigger, bulking before the bear's wide eyes.

As they tensed and rippled like real muscle, it seemed to excite the mute bruin even more. His paws slid along Tachi's front, moving through the thick hair coating it, before drawing his arms slowly down along the wolf's waist while his massive chest and abdomen pressed up against Tachi's great muscle gut and mountainous pecs. Their muzzles moved close as they leaned in, Lorank pressing his lips to Tachi's.

Fortunately for Bobert, he was right in the middle. He was engulfed in pectoral muscle and musky chest hair, sliding along his form while his lower half was caught between brick-like abs and a great planetary belly. The otter gasped and pressed against the walls of soft muscle, trying to push them apart, or at least, get out from between, but they were steadily pressing harder against each other.

The wolf's arms raised to wrap around Lorank's broad neck and shoulders, sliding his fingers through those red locks as their lips meshed. Tachi shuddered at the ever-increasing warmth between them, despite Bobert being caught in the middle. The otter seemed to be enjoying it, feeling the rubs and pinches the male was giving them at their middles. Tachi grinded forward, squeezing him further as their lips locked further, nipples starting to mesh from their grinds.

Saliva trickled down Lorank's chin, dripping down along the crevice of their hairy valleys, though enough got through that it began to splash onto Bobert's pinned form. It slid over his hair and head while the musk engulfed him, causing the otter to groan and shove a bit more against them, listening to the deep rumbles and gurgles of both beasts' stomachs against him. He pressed upward, reaching to comb through more of that hair while the drool dribbled onto him.

Tachi felt their fat nipples meshing together, pressing firmly before his own sank forward into Lorank's. He winced, feeling them almost squeeze his own with their firmness, feeling them bloat and pulse, getting thicker from their arousals. The wolf was steadily slobbering into the bear's gaping maw, their lips sliding over each other as they shared increasing passion with each other. Neither of them could get enough of each other.

Their pecs were soon matted with saliva and sweat as the heat increased, the musk building around them from their gargantuan size. Bobert was being coated with all of it, moaning from between them as precum splattered from his cock, gushing over the lower garments the two beasts wore. He stroked and squeezed, groped and gripped where he could. His small paws could barely reach anything, but that didn't keep him from trying.

"You seem to like this body, Lorank," the wolf murmured between parting their lips to breathe, diving back in soon after.

Lorank's eyes opened, nodding quickly before he pressed more firmly against the wolf, his huge junk sliding and slapping against Tachi's. It bulged and strained his garment before it broke off rather quickly, leaving the massive, black cock to rise up against Tachi's junk, which was also steadily swelling. The bear gripped against the wolf's form even tighter, grinding against him as he breathed and huffed with growing lust. It had been a very long time since he had someone big enough to take his entirety.

Bobert had almost passed out from the rough squeezes and flexes around him, moaning coming muffled from beneath the masses of muscle he was being crushed into. The musk was overriding his senses and he could do nothing but enjoy the saliva and sweat that was steadily dripping all over him. His cock was making a huge puddle below until Lorank's massive cock shoved upward, feeling it shoving against his feet while it shoved to Tachi's junk.

Feeling the insistent thrusts from the bear, Tachi grinned and grinded back, growling to the beastly bruin while their lips meshed even more. His sheet-like covering creaked and strained before it tumbled away as well so the two black spires of meat could shove and slide against each other. Precum dribbled from both tips as their arousals grew, the wolf leaning back a bit more as he sat against the bench. Tachi felt the otter stagger from between them, dripping with both of their liquids, until he slowly brought himself to the head of the bench while Tachi leaned back.

"You guys caught me in the middle of my workout... going to have to keep pumping," Tachi murmured with a grin, gripping the bar. However, he lifted his thighs up, sliding them against Lorank's and hooked himself close, grinning to the panting bear.

"I agree... slut. Keep pumping... while we pump you," Bobert panted, obviously out of breath from his earlier predicament. He seemed to regain himself quickly, though, and shoved his cock along Tachi's face.

Instead of recoiling like before, the wolf spread his lips and eagerly sucked on the fat cockhead, trailing his tongue to bathe the dripping head, smearing the precum about. He listened to the otter's groans, feeling him shove forward and spread his throat. Tachi responded by swallowing over it, lifting his hips and began to gyrate against the bear's cock, who eagerly pushed back, growling like the giant he was.

Lorank drew his huge paws down, sliding against Tachi's thighs before he spread them, shoving his throbbing cockhead into the bulky ass of the wolf. Surprised that it spread so easily, he entered, letting his huge head squeeze through, sinking deeper and deeper while he bared his teeth and gave a deep growl. He arched further, watching that waist bulge only slightly and accept more of it.

Tachi winced and squirmed at the huge length--even though he had grown, Lorank was still gigantic, even for his size. It spread his ass slowly while it pushed deeper, pressing down a bit harder while he squirmed on the bench. Sweat dripped down his hairy body while he gripped the bar above him, starting to pull it off the clasp to lower it. When it brushed against his chest, he lifted again, causing his gigantic mounds to bulge bigger, raising upward.

Bobert sank his cock into Tachi's maw while he spread it, watching his throat bulge and the hair ripple with the movements of the member beneath. He groaned as the wolf immediately went to swallowing and sucking over the thick meat, squeezing with the powerful muscles moving through the wolf's chest. The otter gripped the huge shoulders that rippled with the movements, watching the bar rise and fall in front of him.

The monstrous bear cock was steadily pushing through the wolf's body, watching that belly and chest bulge out with the shape, but grunted as his waist pressed between the wolf's thighs, fat blond-covered balls squeezed between him and that waist. He panted, shuddering at the heavy ripples around his gigantic dick, leaning over slightly to grip against the wolf's broad waist. It had been so long that he felt his entire length squeezed at once. Sweat dripped down his face as he looked down at Tachi with wide eyes, watching him swallow Bobert's cock.

Tachi was tensing and flexing where he could, massaging over both Lorank's and Bobert's cocks. He sucked and slurped, rolled his hips and squeezed them together while they both shoved into him, making him moan, even though it was muffled. His nose was buried into the huge nuts of the otter, though he took in the scent with shudders and grunts while he continued his set. His rump clenched harder around Lorank as he felt him pull backward, the deep growl of the beast causing him to shudder.

Lorank was hanging over Tachi, almost wanting to lie down on him, but he let his cock pull back half-way before he shoved in again, his groans only getting louder while he felt it engulfed once more. He wasn't as vocal most of the time, but the feeling was too good to keep quiet. His growls were deep, shaking the floor while he looked down at Tachi, bringing himself back and slamming forward again, leaving Tachi to shove harder into Bobert's groin.

At the feel of being knocked around so easily, Tachi quickly latched the weighted bar, fearing he may drop it. He stayed spit-roasted, however, and brought his arms slowly down to engulf the otter's waist. His paws slipped down, gripping into Bobert's thick rump while it shifted with his thrusts, feeling those cheeks flex with effort to drive himself inward. His thighs gripped more firmly into Lorank's waist, drawing himself to slam down while he pulled Bobert with him.

Saliva was spilling over the otter's cock while precum dribbled back around Lorank's mighty dick. Tachi felt his belly pushing upward with both of the men's liquids, but his rump clenched to pull Lorank in harder, his rump almost sucking the bear's dick deeper. He rolled forward and back, sliding between both of the monstrous dicks while he stroked along Bobert's back, whimpering around the huge member while he was taken from both ends.

Lorank's grunts grew more vicious while he slammed deeper and harder, leaving the bench to creep along the slightly-padded flooring. He gripped onto Tachi a bit harder while he slammed, his huge, hairy balls along the floor and bench itself, gurgling and sloshing with a steadily-building amount to pump into the squirming, beastly wolf beneath him. He was leaning over now, pressing his massive pecs into the wolf while he lifted his head to lap and kiss at Bobert's chest and face, coating him in more saliva.

Bobert sputtered at the saliva soon splashing into his face again, kissing back a few times before he pulled his face back slightly.

"Nngh... stop that, you big lug," the otter panted, grinning, "make out with the slu--oh yeah..." He gave another thrust, having almost forgotten that he was fucking the wolf's face.

Lorank gave a growling huff before slurping the otter's face once more, soon lowering his head to kiss and trail his tongue over the wolf's spread muzzle. He moved down to lap and nibble on the wolf's bloated neck, feeling the moving member beneath the thick beard that the wolf had grown. He huffed as saliva coated the blond fluff that the wolf now had, sucking against his neck while Bobert groaned louder from the increased pressure around his cock.

The precum was bubbling up in the wolf's belly. It was swelling from both cocks slamming through him, feeling them sliding along each other and grinding against the tips, Bobert's even sinking into Lorank's through some of the thrusts. He was gripping around the wolf and the bench now, slamming harder into him as his balls churned. He panted, lapping into the gigantic bush that had grown over Tachi's chest, snorting in that powerful scent deep between them.

Tachi drew his arms up to squeeze into Lorank's massive muscle tits, feeling them flaring beneath his touch as he sucked on Bobert's dick more and more. It slipped down his throat harder with his heavier thrusts, hearing the otter's grunts through his jabs. The sweat coated him so thoroughly that it was dripping onto the floor around them, leaving the musk to spread further through the room. His great, black cock was pinned between himself and the bear above him.

Precum coated all three of them as Tachi arched, the great, black member splattering between their huge chests and even splattering on Bobert's front. They were all groaning and grunting over each other, two gigantic beasts under the command of small, huge-cocked mustelid who was holding both of their heads. The otter's fingers coiled through their sweaty locks of red and blond, tugging them a bit while he slammed forward.

Lorank seemed to grunt and tug back, however, looking up at the otter somewhat with his blue eyes. He smirked a bit at the tugs before he went back to smothering his own muzzle into the forest of blond that had engulfed the gigantic wolf's cream-furred pecs. He snorted and snuffled his muzzle against it, soon moving over to one of those big, black nipples to latch and suck on. His fat tongue slid against it, feeling it throb and firm beneath his lips.

Tachi squirmed and arched, rolling his eyes back while he was pleasured and assaulted in all manners. His nipples were hard, sweat dripping down his flesh while Lorank sucked, leaving him to grip his huge arms around the bear's head to hold him there, smothering his face into that huge tit all the more. He felt Lorank grunt and squirm somewhat at the surprising strength, but he continued to suck and slurp to pleasure the clenching wolf.

Everything was clouding his mind. The scent of his master otter, the weight and smell of the bear, the two monstrous cocks inside of him, and the precum stretching his belly was too much for him to handle. His cock flared, bulging up between their massive, hairy bodies, and he exploded. Cum gushed from his dick and fired along their mountainous pecs, gushing so hard that it splattered against Bobert's front. The spasming caused the wolf's inner muscles to clench like a vice, his throat pulling on the otter's like a vacuum.

Lorank and Bobert both felt the sudden suction around their cocks, leaving them both to gasp and grunt, thrusting a bit harder while their dicks slid against each other inside the wolf. The friction from all sides was enough for both of them to seize up.

The otter was the first to moan and cry out with orgasm, his titanic balls pulling up before erupting with cum into the wolf's body. The underside rippled through that throat and gushed gallons and gallons into that belly, flooding around Lorank's cock, adding more heat and pressure to it while he humped. He leaned over Tachi's head and held onto Lorank's, squeezing into his thick hair while his orgasm raged through him.

Lorank held off as long as he could, but the grip around his entire dick was too much. With the added heat and gushing of Bobert's semen, the bear gripped roughly around the wolf and belch, roaring out like a monster, himself. His cum added to the swell already there, but his own seemed to splatter out from around his cock. That belly surged, however, and began to push the bear up. The heavy splatters of cum sounded below the roars of the bear, still arching and thrusting in sharp, hard ruts.

Tachi was squirming in the throes of pleasure. He felt the pressure increasing at his belly, feeling it creaking and straining with the steady pumping of both of the big, black dicks pushing through him. Sweat was pouring from his form, but was covered by a lot of the cum that he was gushing. He thrusted and arched between them. With the pressure increasing, the cum splattered harder from his wide rump, around Lorank's massive dick.

It was difficult to say how long they were splattering into and over each other. Tachi's torso was getting so tight that some of the otter cum even splashed from his maw around Bobert's member. The wolf's pecs had pushed up from the liquid gushing through him, but it was steadily being forced out through their hard pistons. Tachi rubbed where he could, caressing the bear's head and along Bobert's side, holding him tight to his maw.

Bobert was the first to slow, coming to a trickle, but he kept his cock deep within that throat as Lorank continued gushing, just to make sure that the slut didn't belch up his cum. He had plans for that. He stroked along the cheek and beard of the wolf beneath, watching him shiver and tense from the bear unloading into him. The pressure almost caused him to get pushed back, but he kept deep inside, giving a few more grinds into him.

Tachi was next to come down from his orgasm, followed quickly by Lorank. There was a massive amount of seed along the floor, but not nearly as much as usual. The wolf had taken almost all of it. Tachi sloshed heavily, looking rounder at the middle than usual, even if it was tight as a drum. He felt Lorank slowly pulling back until the massive dick flopped out, hitting the floor with a heavy, meaty thud while a deluge of cum followed.

After Lorank had finished, Bobert let his own huge meat slide from the wolf's maw, slapping over his tire-sized balls and drip with the last bits of cum. He panted, stroking along his softening member while he saw the slut smile up at him, dripping with cum over his muzzle as he audibly swallowed the rest down. A grin came over his own muzzle.

The bear was breathing hard, massive pecs rising and falling with their size, slowly bringing himself to slide to the side of the bloated wolf. He leaned down, trailing his huge paw along the wolf's cheek after Bobert had pulled back, looking over his masculine, hairy face that had been disheveled and mussed. He used his big fingers to smooth the beard back into place, combing his hair down and smooth once more, though he leaned down and pressed his lips to Tachi's once more.

When their kiss began, Tachi tilted his head and let his own lips mesh tightly, saliva already pooling through their sloppiness. The bear's tongue filled his maw, causing him to sputter somewhat, but he eagerly sucked on it afterward while his own slid against it and coiled where it could. The huge red arms gripped around his form once more, the great paw stroking through the blond hair while their oral appendages played.

Bobert grinned while he watched the two beasts make out, reaching forward to trail his fingers through the mops of blond and red, feeling the thick, moist hair curl around his fingers while he kneaded between their ears. The sight made his cock throb again, but he remained quiet while his huge bear friend took his slut on a slippery slope of salivating tongue.

After a few more minutes of lip-lock, the great bruin pulled back and panted, smiling down at the huge wolf while he combed through those blond strands as well.

"Slut," the great bear rumbled as he did at the festival, voice shaking the wolf and otter, as well as the room itself.

It was the second time that Tachi heard the bear speak in the matter of weeks and it caused his cock to surge once more while his eyes widened. Bobert must've told them to call him that--or maybe he was truly acting like a slut. He couldn't deny it, he wanted a second round already with his cock throbbing against his bloated, gurgling belly. He lifted up and kissed the bear once more, licking along his chin while the big bear growled out in bliss.

Lorank looked at the clock on a nearby wall and huffed. After a moment of deliberation, he brought his paw to Tachi's cheek and leaned in to kiss him once more, though forlornly took himself away and pointed at the clock.

Tachi looked to it and nodded somewhat.

"It's alright, big bear, I understand. You've gotta get back to your hotel. Thanks for coming to see me," the wolf rumbled, lifting himself up and squeezing against the bear's chest, to which Lorank gripped around his shoulders in reply.

Lorank reached down and rubbed against Tachi's chest, soon sliding along that arm as he trailed his fingers between the wolf's, lifting his paw up and seeing that they almost perfectly matched in size. He looked to Tachi and grunted, holding the paw up a bit as if motioning to it.

"Oh, I'll be like this for a while, Lorank, don't worry. We'll probably have more fun soon, I'll come see you and we can play around in the hot spring. Who knows, I might end up getting bigger if Bobert fills me up a bit more," Tachi chuckled, soon kissing Lorank's big, red paw.

Lorank seemed relieved, smiling and smooching the wolf's nose before pulling back once more. He waved to the huge wolf and then gave a light bow to Bobert before turning and departing the gym, seeming bouncier than when he had arrived.

Tachi sighed in delight, looking down at the grinning otter afterward, though perked his ears. He had half-expected the otter to follow the bear out.

"Sir?" the wolf asked, tilting his head in confusion.

"Hm? What?" Bobert asked, blinking up to the wolf as he walked forward, gripping into that belly.

As if instinctually, Tachi drew his massive arms around the otter's lithe body and lifted him up, sliding him atop the massive, straining belly and against his huge, hairy chest.

"Are you not leaving?" Tachi asked.

"No, do you want me to?" Bobert replied with a raised eyebrow.

"N-no sir, no! Of course not, especially if you want to stay."

"Good. Since it's the last two days of the week, I think I'm gonna spend most of them with you."

Tachi's face reddened slightly at the prospect.

"I'd like that," the wolf murmured in a whisper, trailing his huge muzzle along the otter's neck and chin, kissing it lightly.

The otter churred softly to the affection, trailing his paw along the thick beard of the wolf, tugging it lightly while grinning.

Tachi growled and kissed a bit more as he brought the otter upstairs, flicking his thick, blond tail behind him. His belly was gurgling, though not as heavily as it normally did--perhaps it was because of the heavy bear cream that came with the otter's. He grunted, however, as heat built up through his form. He held the otter closer while he breathed heavily, stomping a bit heavier up the stairs. As he reached his living area, the wolf moved through and shut the door behind him. He huffed a bit as sweat trickled down his cheek.

"You okay, slut?" the otter asked, tilting his head.

"Y-yeah, this is when... your cum makes me grow," the wolf chuckled sheepishly, grunting as his gut gurgled louder, leaving him to wince a bit.

Bobert perked a bit, a more mischievous grin sliding over his muzzle.

"That quick?" the otter asked.

Tachi nodded, grunting again as he quickly moved through the hallway into his bedroom. He huffed and shuddered as his cock throbbed upward, starting to rise with the growing heat while he gently scooted into the silky covers with the otter in his arms. His massive body now covered most of the bed, save for a bit of width. What would once fit five or six of Tachi now only fit one. He had to bring his arm around the otter to keep him up, to make sure he wasn't pushed off the bed.

The heat was steadily growing along the wolf's body as his grunts grew louder, arching somewhat while he lifted his head against his pillow. He watched the otter crawl up along his chest and then settled on his gurgling belly. Tachi lifted his paw and stroked along the back of his little master, smiling at him through his growing haze, but soon lifted his head back again as he breathed roughly. A pulse shot through his form, leaving him to tense and snort.

Bobert rubbed through the hair-covered belly, feeling it practically rippling beneath his touch. He squeezed into it while he listened to the grunts and groans of his slut, watching his muscles tensing and flaring beneath the thick fur surrounding him. The heat radiating from that noisy middle was causing him to perspire as well, wiping his brow and combing his locks back to squeeze against the surface a bit more.

Tachi's body was tensing harder, his thick claws gripping into the sheets and mattress beneath. He snarled and arched, groaning louder, though not in pain. Precum was gushing from the huge cockhead, causing the monstrous wolf to moan further. He shakily reached a paw up to grip against Bobert's back, holding him against the hairy muscle gut he had, grinding up against him while he panted and snorted, steam bursting from his nostrils.

The pelt of the wolf looked to be straining while the muscles flared beneath it. His form rippled over the bed, pushing over it all the more, shuffling the blankets about. He growled deeper, his form tensing while his teeth bared as pops and snaps sounded through the room. His tendons were realigning to better support the throbbing muscles, which were steadily tensing bigger now. They bulged all over, through an arm and pushing up a pec, his calf and thigh tensing bigger and expanding against the bed.

"F-fuck... fuck, sir... it feels so good..." the wolf gasped, his voice deepening even more, almost sounding too bassy to understand.

"Hush, slut. Keep growing," Bobert grunted as he felt the belly moving further beneath him, spreading his arms and legs out as he lied atop.

The wolf gave a deep, grunting whimper while his form expanded further, filling the bed more and more until his feet were starting to press past the edge of the mattress. His claws almost shredded the silky sheets beneath him, but he was careful not to squeeze too hard. That body was dripping with sweat, however, and coated the sheets regardless. He was breathing harder while his cock throbbed, shoving against the otter along his belly.

Bobert sputtered in the shower of precum that he was getting, reaching up and squeezing along the gigantic length that was steadily spreading wider. He pumped the stretching flesh while he brought his feet down, shoving them along Tachi's huge, hairy tits while the hair bristled and spread over more of those mounds. His toes clenched around the fattening, black nubs that were nearly the size of tires, themselves.

Tachi was scratching at his chest now while the fur bristled, feeling his beard thickening while his hair lengthened all over. It was still being overshadowed by the growth of the muscle beneath it, but it increased the thickness of scent just the same. His claws seemed sharper while his teeth grew more visible between his large lips, saliva trickling down his chin while he tried to bear the strength that was adding to his frame.

The belly slacked somewhat, though was still quite soft and pudgy beneath the otter's movements, but those pecs pushed up, forcing their way around his muzzle while his head was pushed back. His groans were shaking the walls while his cock splattered the canopy above, precum gushing at a copious rate. The otter was being coated quite thoroughly while the wolf arched and grinded, snarling while his back pressed him upward from its expansion.

The wolf's blond hair covered most of his cream fur, now. It draped all over, giving him almost a regal look, but it was still somewhat matted through the sweat his great body was producing. He arched as he felt Bobert going at his cock all the more, feeling the arms squeezing and sliding up his length while he squirmed and gripped the bed a bit more. His entire back now covered the surface of the bed while his feet were hanging near the floor.

After gaining another couple of feet and what seemed like a few more hundred pounds, the creaking bed almost gave way when the otter pumped mercilessly at the spire of black. Tachi lifted his head back further, gasping and grunting, his groans growing to a gigantic howl, once more sounding like a beast from Hell to wreak havoc amongst the city. Windows shattered, glasses broke, and the sound waves sent a crack through the very walls of the room.

Bobert winced at the roar, but more so at the gargantuan cock erupting with its liquids. He felt the bulges along the underside before it exploded upward, firing through the ceiling and breaking the plaster apart. Gush after powerful, volcanic gush flooded the room and through the ceiling, causing another hole before it was brought down enough to splatter widely. Tens of gallons of cum were flooding the room all the more, starting to gush through the hallway and, once again, down the stairwell.

The otter's jaw went slack at the sight of so much semen. Those balls were nearly hanging to the floor from the bed, too, but they were clenching and pulling up with each gargantuan gush. The walls were coated, the ceiling, most of the furniture in the room, as well as Bobert himself, while the gallons splattered with heavy, wet plops and spurts. Everything was doused in white while it rushed through the hallway and down the stairs, and would remain as such until later.

Half an hour had passed before the wolf finally came down from his orgasm, leaving him shivering and gasping in pleasure. He brought his paw up and reached for the otter, soon drawing him forward while he dripped all over. The wolf trailed heavy, sloppy licks over the otter's face and neck, over his chest and hair to clean him, hot breath wafting over the mustelid's face.

Bobert grunted as he was moved along that hairy gut and chest, soon gasping as that tongue bathed him. He dripped with saliva instead of cum, now, and kissed against the big appendage as it trailed close enough. He pressed closer into his huge slut, soon burying somewhat into his thick hair while he breathed in that scent, kissing against that huge muzzle and holding his cheeks.

"Good slut..." the otter panted, looking into those blue-green eyes with his own blue ones.

Tachi's hazy expression was soon pushed away as he heard the praise, his face red once more while he kissed against the otter's lips in reply. His gigantic arms came more thoroughly around him, despite both of them covered in white. He rolled to his side somewhat, smothering the otter into the gigantic muscle tits while the wolf breathed deeply, swiveling his ears with a sheepish smile down to the otter.

"Thank you, sir," the wolf whispered, kissing him once more before engulfing the otter into more fur and muscle, letting him breathe in nothing but the powerful, masculine scent of his monstrous form.

"We'll have to get some food afterward, I wanna bloat this belly up more," Bobert murmured, kneading into the belly he was pressed against.

"Yes sir. You can feed me as much as you want," the wolf replied with a smile.

The otter nodded, burying his face into that thick beard as his breathing grew shallow, followed by the wolf's as they dozed with each other.

*****

Sometime during the morning, Bobert had scampered out of the gym without much of an explanation. He simply said he would be back in the afternoon after he finished his preparations. He gave a slap to the big belly to make it wobble, still having quite a bit of heft from the practical buffet the otter shoved down the wolf's gullet in the previous night. The otter trotted out while the cleaners began another round of work.

It was the last day of the week and Tachi shuddered with excitement. Whatever Bobert was planning, it was going to be good. He was having to bend down farther to fit through the doors and there was no chance he would fit in the broom closet anymore. He'd have to hire a full-time janitor at this rate. Nonetheless, he had finished his workout for the day and grabbed a towel. He had grown so large that Alus's clothes would no longer fit.

After he got the sheet-like towel, he wrapped it around himself and headed toward the wooden door on the side of the gym. He tugged it open to let a billow of steam rush out, bending down to push through and enter the doorway. The log-lined room was rather large in itself and would seat even Tachi's size comfortably, especially since there was no one else in it. He sighed in delight as the scented clouds meshed through his fur, soon settling down along one of the large benches inside. The steam was already causing his fur to mat, water dripping from his form after it collected there.

Minutes passed while he dripped with water. The wolf lifted his head back and settled it against one of the logs, sighing in delight as he simply relaxed inside. Sweat began to mix with the moisture in his fur to cause his scent to overpower the sandalwood of the steam. His masculinity was even more apparent with his blond hair pressing more closely to his frame, looking even more massive than he usually was, considering there was a lot of fluff there.

Even the steam couldn't block out the sudden scent of otter, however, or the cool air that meshed with the steam. Tachi stirred from his relaxation, perking and looking forward, seeing a towel-covered Bobert before him. It was a large towel, but even it couldn't cover the entirety of the huge otter cock below with his head nearly touching the moist floor. It was already dripping with that sticky, clear liquid.

"Hello, sir," the wolf murmured with a lazy smile, sitting up slightly more attentively.

"Ready for the finale, slut?" Bobert asked with an increasingly-malicious smirk.

"T-the finale?" the wolf asked, a bit nervous from the expression.

Behind him, the large, midnight-furred squirrel pushed through, looking just as large as he had been whenever he wrestled the gigantic wolf--his waist was covered with a towel as well. Following Vincent, the red-headed mouse was quickly moving in, his golden eyes glinting in the dim light. The two men moved forward and slid to the massive sides of the wolf, bushy and thin tail flicking about.

"O-oh... Hello Vince, Jeff. I didn't expect you guys so soon again..." Tachi murmured with a grin, bringing his gigantic arms slowly along the rodents' shoulders, drawing them into the thick bushes beneath his arms. He growled out in delight at the feel of their muzzles shoving into those pits, his musk engulfing them and causing both of their cocks to swell and lift their towels.

"Couldn't keep away from you too long, big slut," the squirrel rumbled, snorting in that scent while that huge arm locked his muzzle into that muscled pit. He growled, lapping deeply while he gripped into one of those gigantic nipples, tugging and thumbing along the edge of the cups they had formed.

"We needed another piece when Bobert so graciously offered more fun," Jeffery stated, doing the same as his squirrel companion. His face was easily hidden in the thick bushes beneath that arm while he stroked the other fat, black nipple.

Bobert smirked a bit more and then growled, slowly drawing himself toward Tachi and stroked along the towel-covered member below.

"Gonna join in this time, sir?" the wolf asked with a sheepish smile.

"Of course, slut. This isn't everyone, though," Bobert murmured while he lifted his paw up, patting the wolf's blushing cheek.

Behind Bobert lumbered one more massive figure, pushing through with his own towel. Lorank smirked down at the wolf while he entered, shutting the small door behind him. He lumbered forward and leaned his head down, pressing his thick lips against Tachi's, tilting his head while he trails his fat tongue into that maw.

Tachi blinked at the sight of the gigantic form, smirking a bit after those lips met his own. He closed his eyes, drawing his paw up to grip against one of those arms, further locking Vincent and Jeffery into his blond-covered pits. Their tongues meshed, saliva once again dribbling down their chins while they made out. The wolf drew his paws along the rodents' backs while he grunted, though blinked as Lorank pulled back and licked his own lips.

The big bear looked around and then grinned, slipping himself down onto the floor while his towel spilled off his junk. He rubbed the surface of the throbbing, black cock as the four new arrivals gained moisture over their bodies. The steam was billowing over their muscularity and flesh, matting slowly to show off more of their size--save for the otter, of course. He wasn't as muscular, but he still had his own swimmer's build.

As Lorank slid to the floor, Tachi watched him rub that length. The wolf rubbed his chin somewhat and released the squirrel and mouse, leaving them to gasp and pant while sweat dripped from their faces. He leaned forward, kissing against Bobert's muzzle before he stood, walking over to Lorank and lowering himself. His cock was throbbing while the towels slipped off, all five of the men naked for each other.

While Lorank's cock throbbed higher, the wolf turned and slowly slid his huge form along the bear's, sliding down into that lap to let his huge rump fold over the broad member. He was a bit bigger than the bear considering the previous day's increase, but the bear drew his arms around that waist to grip at Tachi's cock. Tachi gasped and arched, his gigantic black spire lifting upward through the stimulation, feeling himself being lifted by the large bear cock beneath.

While this was happening, Bobert waltzed up and then crawled along the thick, hairy front of his slut and brought his hardening otter cock against the wolf's face. As Tachi opened his maw, that fat head shoved deeply within his maw and throat, working it forward to push it down the neck of his slut, watching it bulge with his shape, precum already spilling down from the suction the wolf provided.

Vincent and Jeffery both approached to the sides again, trailing along the wolf's nipples and squeezing along their thickness. The middle of each one was puffy, the hole visible and obvious in the folds of the nub. The mouse pressed his thumb into the center, watching it easily sink in and feeling the squeeze of the flesh around it. He shuddered, pumping it a bit deeper as he used his other paw to spread it further.

"Damn... I bet we could fuck these," Jeffery murmured to Vincent, smirking at him while he stretched the firming flesh a bit more.

Vincent's red eyes lit up, looking to Jeffery's assault on the fat nub, smirking and drawing his fingers along the edge of the one he was near.

Tachi panted and gasped at the fondling to his nubs, arching somewhat and groaning around the huge otter dick in his maw. He brought his paws forward, caressing through the tightly-curled hair of the mouse and the long dark locks of the midnight squirrel. His chest tensed, pressing and bulking out against them while they stroked and tugged, leaving the wolf to breathe a bit harder, taking longer sucks over the otter's cock.

Adjusting his swelling member, Lorank began to lift the wolf upward, feeling him stand before his massive head shoved against the wolf's backside. He felt the creak and gray cheeks spreading more and more over it before the fat, black tailhole shoved along the head and began descending. Lorank groaned in pleasure at the quickness of it all, feeling those walls gripping him while he pressed upward. Foot after massive foot of bear meat sank into Tachi until the wolf was, once again, sitting in Lorank's lap.

Vincent lifted his thighs up whenever Tachi was lowered back down, his throbbing, pink cock slipping along the front of that mountainous, hairy chest. His tip kissed against the squishy nipple, feeling the flesh starting to spread around it with the more pressure he added behind it. With a groaning grunt, the dark rodent popped the head behind the nub, soon pushing forward while that pec bulged out with the bulge.

The wolf's reaction was instant. He clenched, giving a loud groan around Bobert's fat dick while his body rippled and tensed around the gigantic bear cock. His pecs bulged, seeming to bloat a bit bigger while the right one was invaded by the throbbing meat. Tachi squeezed against Vincent's shoulder, but pulled him forward to cause him to enter deeper. The pleasure was electrifying, leaving him t spasm and moan, muffled around dick.

Jeffery watched with curiosity. The bigger squirrel cock entered with surprising ease, so it encouraged him to lift up and do the same. His own big, pink cock slid along the unfilled nub, spreading it around his tip before he inched upward more slowly. The clench of the massive muscle tit caused him to gasp and arch, sending another foot of mouse dick into the huge mound. Both rodents were sinking deeper and deeper until their hairy groins were shoved up to the fat, black nubs, bulging those mounds out with cylindrical shapes.

Tachi's eyes were rolling back from the pleasure already coursing through him. His precum splattered on the far wall while he was penetrated in each hole, save for his navel, and moaned louder as he sucked harder on Bobert's member. He slurped and drank it down, feeling it throbbing in his neck and chest while the otter humped. Tachi was squeezing where he could, be it through his flexing pec mounds, his neck, or his inner walls to grip around Lorank's cock.

Those massive gray-furred thighs tensed as he lifted himself up on the bear's member before slamming back down again, sending all four of the grinding males to squirm about in attempts to get deeper into the slutty wolf. He gripped onto Jeffery and Vincent, stroking their shoulders as their hips drew back, sliding their dribbling cocks half-way out before shoving in again, starting to fuck the pecs that they were so engrossed with.

Bobert was enjoying all the bulges moving through Tachi's figure. Even those gigantic muscles couldn't hide the sizes of each of their huge cocks, all of them pushing into the wolf in some form. Those pecs wobbled with their size, the huge belly was stretching with bear cock, while that throat rippled around the otter's member. Precum was gushing from each of them, sending more ripples beneath the pelt and muscle of the monstrous wolf.

Each flex of those pecs caused the rodent cocks to be pulled in deeper, practically sucking them in. He tensed them and bounced them in alternating bounds, causing Vincent and Jeffery to give out wavering groans between each other. The wolf was lifting up and pushing down, sucking on every one of them in some way, each hole rippling to tug and squeeze. All four of the males were moaning while thrusting into the wolf, every bit of the wolf's form rippling and bouncing.

Lorank was growling while he gripped harder around Tachi's waist, lifting him up a few feet before slamming back down, leaving the wolf to gurgle and gasp in muffled moans over Bobert's fat otter cock. The bear squeezed along that hairy gut, rubbing his own cock through that muscle and flesh, arching harder and grinding with deeper, louder growls and grunts. He buried his face into Tachi's thick mane, snorting while the huge bear fucked him.

Precum was filling his belly at an alarming rate. Tachi's stomach bulged along his huge, black cock that the otter was sitting on, soon having to crawl up the swell to better get at that broad muzzle. The wolf grinded himself up and down, sucked, and flexed his mammoth tits around everyone; the pleasure running through his body was numbing him. His eyes were rolled back and the steam didn't help--his body was completely soaked with sweat and water moisture. He began rubbing where he could, over all four of the men that were using him.

It felt as if Lorank's cock was steadily swelling inside of Tachi, bloating thicker to stretch him wider. He swelled fatter and heavier over that cock, aided by the otter's gushing member down his throat. The precum that was flooding into his pecs would cause them to bloat as well. They pumped thicker and heftier, the sticky liquid seeming to simply add to the muscularity itself. Tachi rolled himself back, forth, up, and down, trying his best to squeeze and tense where he could.

The steam was billowing, but it wasn't overcoming the sheer scent of masculinity filling the room. Their copious sweat was drenching each other, meshed together so their massive forms grinded and smacked against the meaty walls around them. They were pressing so close to each other that their muscles were folding over muscles, slapping with heavy, wet thuds while Tachi bloated with more liquids from his companions.

Vincent and Jeffery were slamming deeper into those massive mountains, feeling them ripple and slap together with their size, but the bloating continued while they filled him with precum. It was obvious they were getting closer to their orgasm with how tightly they were gripping to the mounds. They soon squeezed onto the wolf's shoulders to steady themselves, rolling and arching with harder ruts.

Tachi's paws gripped the rumps of both squirrel and mouse, tugging them harder into his chest while he arched against them, sliding up Lorank's huge dick in the process. His back slid against the bear's thick abs and huge, hairy tits while he lifted his head and slammed down on Bobert's dick. His own cock was throbbing harder from all the stimulation, spraying the wooden door and walls with thick gouts of precum. His balls were gurgling audibly as he neared his own orgasm.

As Vincent and Jeffery arched a few more times, they both gasped and snarled. The squirrel gave a few more hard thrusts while Jeffery let out a deep, heavy squeak before they erupted into Tachi. The sensation of hair, fur, and muscle was too much grinding against their fronts that they unleashed their cum into those tits directly, causing them to flare up and swell out, starting to bulge with so much cum. Heavy spurts began to erupt from around their dicks, firing out of the fat, black nipples that were being stretched.

The wolf gave a loud howl around the otter dick in his throat, muffling it and sending vibrations through Bobert's member. It was like a chain reaction at that point. As his gargantuan chest was filled with semen, Tachi's own cock flared, bulging and sending an eruption of white out as well. It hit and splattered against the ceiling and walls of the sauna, leaving him to clench and grip not unlike the day before, rolling harder over Lorank's gigantic member.

While the sound waves moved through his dick, Bobert clenched, gripping his slut's blond headfur as he shoved and thrusted, gasping and panting in bliss. His fat balls slapped against those swelling mounds, feeling them pressing him up and backward while the two rodents filled them so thoroughly. After a few more rough, slapping thrusts, the otter cock let loose next. Gallons cascaded downward, flooding that belly directly.

Lorank was the last to explode. The great bear cock throbbed hard in the wolf's broad body, gripping around his waist as that belly swelled with otter cum. He felt the liquid heat around his member, along with the vice that crushed against his fat dick, and finally was led to his own peak. The bear roared with the other three while cum shoved through the wolf's body, filling that belly once more. His own eruption was greater than Bobert's, though both flooded Tachi's stomach regardless.

Tachi's eyes rolled back once more while he orgasmed and while he was orgasmed into. His entire torso was spreading against the four. His back pressed harder into Lorank's front while his gigantic muscle tits were shoving against Vincent, Jeffery, and Bobert. That belly stretched bigger, straining outward while he squirmed, forced to take every bit of it and unable to push any out. His maw was locked around the otter cock while his rump clenched over bear cock.

The squirrel and mouse were the first to die down, Jeffery pulling out first. The fat nipple let a gush of white splatter from pressure, trickling soon after. When Vincent pulled back, the other did the same. The huge pecs were hanging down and heavy with so much new size that it was a wonder they weren't engulfing his entire head. They grinned and gave a few wet pops of their paws against the jostling mounds.

Bobert was the next to finish after having dumped a few ten gallons of otter spunk into him. He slowly slipped out and let his fat cock slide along those mammoth mounds, a few more spurts firing from it before it trickled as well. He pulled back, letting his cock slap down between his thighs. He watched that belly bloating, listening to the straining creaks as the wolf squirmed in discomfort.

Lorank's own orgasm slowed after the wolf's came down, arching forward and then slowly pulling him upward. Easing Tachi back to the floor with his own powerful strength, Lorank stood and grinned, all four males looking down at his bloated, creaking form. He leaned down, giving a kiss to the wolf's muzzle before he stepped toward the door, waving to them and stepping out after grabbing another towel, sighing in delight. A rush of the wolf's white liquid followed him before he shut the door.

Vincent and Jeffery both took their own kisses, the squirrel stroking through Tachi's hair while he held his own for a few moments; Jeffery trailing small kisses against the thick, bearded jawline. After they drew back, the two bulky rodents grinned and trotted out as well--Vincent was sure to give a sway of his hips and his droopy, massive tail behind him.

"We'll be back again soon, slut. Enjoy your protein," Vincent murmured while Jeffery snickered, both stepping out while more of the white liquid splashed through.

Finally, it was only Tachi and Bobert.

"Enjoy that, slut?" Bobert asked, trailing his fingers through the wolf's cheek, wiping a few strands of saliva and cum from his chin and cheek.

"Y-yes sir... it was very enjoyable..." the wolf panted, barely able to move from being so heavily bloated and weighed down by the hundred or so gallons of spunk sloshing through his upper body.

Bobert hummed to himself and then leaned down, kissing the wolf's muzzle.

Tachi perked and returned the kiss quickly, tilting his head and trailing his tongue through those lips, bringing a paw forward and caressing the otter's thigh. As the kiss parted, the wolf smiled a bit sheepishly.

"Y-you're going to keep coming after this week, right, sir?" the wolf asked softly, ears swiveled while he looked pitifully hopeful.

"Oh, slut, of course I will. Leaving you alone for a while is what broke you of your sluttiness to me, after all," Bobert murmured, sliding that headfur back while he looked into those blue-green eyes.

"Mm... good. Maybe we can see how big I can get," Tachi murmured with a bigger grin.

"Maybe we can. Maybe we can see how big I can get," the otter stated, soon drawing back and turning. His hips swayed while he walked to the door, leaving the wolf bloated on the floor.

**Alternate Ending**

"In fact..." the otter stated, fully shutting the wooden door and stuffing a towel down below to make sure no one else could get in for the time being, "I think we'll do that right now."

Tachi's ears perked, looking to Bobert as he moved back toward him.

"Sir?" the wolf asked in a bit of confusion.

"We're going to see how big I can get--from you," the otter stated, trailing his paw through Tachi's beard and cheek fur once more.

Tachi's face went red while he looked to his black dick.

Bobert's eyes followed, looking to the wolf's member as well, before laughing slighty.

"Oh no, not like that," Bobert stated, soon lifting up what looked like a gun. It had the casing of a regular pistol firearm, but at the barrel, there was a glowing purple liquid. Or, at least, only a dribble remained inside of the glass chamber.

Tachi's eyes widened.

"Where did you get that? ...sir?" the wolf seemed oddly panicked.

"Hmmm...? This? Oh, I swiped it from your room last night. Quite a nightstand you have, slut," Bobert stated, twirling the syringe gun in his paw.

Tachi bit his lower lip, looking at the liquid a bit more while the otter played with it.

"D-did you inject yourself?" the wolf asked as he breathed a bit quicker, though his cock throbbed again. It was rising slowly.

"Sure did, slut. Don't worry, I looked at all the labels. This one increases genital size, huh?" Bobert asked, smirking a bit more.

"Y-yes sir... and... and," the wolf trailed off.

"Appetite?" the otter finished the wolf's sentence, pressing his own throbbing cock against Tachi's cheek.

"Sir... you're... you're gonna get very hungry," Tachi murmured with swiveled ears.

"Good thing I have a gigantic supply of meat to swallow," the otter whispered.

Tachi's face went redder. He swallowed heavily, looking to the otter cock that was already pulsing bigger in front of him. He couldn't move--was this what Bobert was planning all along? A shudder went through him, but it wasn't out of fear. In fact, he pressed forward, giving a kiss to the flaring head, reaching a paw to it and stroking along the length--he wanted it.

"Good slut. I knew you'd want to sink into your master," Bobert rurred, bringing a paw to his huge dick as he rubbed over it, shuddering as it spread his fingers as it throbbed fatter, hanging heavier between his thighs while his balls sloshed, hanging lower and lower after every few pulses. He groaned while it stretched, even sounding out with deep, low creaks while it filled out. The throbs caused it to rise, swelling before the wolf's face.

The wolf's paws slid along the length as it bloated into them, feeling it spreading his fingers apart as he gripped and rolled the flesh between them. He panted and watched it widening, steadily pushing against his chest as it bloated. He watched with wide eyes, always enjoying the results of any of his family's... concoctions. He was a bit careless, but he probably would've given anything to the otter if he wanted it.

Bobert was groaning louder as his cock stretched further, gaining inch after inch every few seconds, both in width and length. It was hot, almost reddening with how much blood was pumping through it. Veins were crawling along the sides, visibly swelling with the growth while those balls sloshed, lowering heavier and wider between his legs. Those thighs had to spread to leave more room for his growing junk, watching it with a lustful drool as it pressed harder and heavier against Tachi's hairy chest, sliding against his chin.

Tachi watched with a daze as it swelled in front of him. He continued stroking it, kissing the swelling head and trailing his tongue along the thick slit that was getting longer along that head, seeming to even stretch around the appendage working over it. He closed his eyes as he felt the precum smearing into his fur once more, slurping deeper along that slit before he shoved his tongue deeply into the head.

The new sensation sent the otter into a thrusting frenzy, shoving the massive head between the wolf's lips while he arched. Thick gouts of that musky liquid splattered down that throat, making it stretch around his length before he pulled back again, gasping as the tongue popped from the sensitive slit. He shook, panting with wide eyes while he looked down at his length, seeing it steadily spreading to a foot wider, gaining two feet more in length, and it was still fattening.

It was then that there was a strange, thick gurgling coming from the giant otter nuts that rested on the moist floor. Bobert shuddered more while he rubbed along his massive cock, bigger than his entire body, and starting to rival Tachi's gigantic form. It was a wonder how the otter was still standing, but he began to lean and grind it against Tachi's chest again, feeling every throb move through his body. The gurgle sounded out again, leaving the otter to gasp and groan in discomfort.

Tachi smiled lightly, trailing his paws against that massive head that pulsed into his face.

"The hunger is already setting in, sir," the wolf murmured, kissing that slit a bit more gently than before.

"Mmnh... I'll keep you close, slut. Well... most of you. I'm sure quite a bit will be... nnngh... gushed all over me and this gym..." Bobert panted, pressing forward while his slit began to spread against the wolf's face.

"Thank you, sir... I hope I fill you enough," Tachi murmured, shoving his muzzle into the thick slit.

The sensation threw Bobert off balance, falling forward against his cock as it suddenly clenched, seizing up and sucking over Tachi's head in an instant. The bloated cockhead stretched with the shape of the wolf's crown, but the huge length already pushed down his neck and began sliding over his shoulders like a gigantic, meaty snake. The otter moaned, rolling his hips uselessly while the slit pressed around the wolf's broad, bloated torso, inching along his form with steady slurps and tugs.

Bobert thrusted harder, almost crazed. The pleasure that was rushing through his body caused his form to tense, completely fascinated with how his growing cock so easily slipped over his slut. Each thrust pushed it over those bloated pecs all the more until the stretched head was pressing over that gigantic ball gut. There were creaks and strains of flesh sounding through the still-steamy sauna, the otter drooling while he pushed, devouring his slut.

A flex and squeeze drew Tachi along the pulsing length. He listened to the thick squelches and slurps that came from around him, shivering at the hungry gurgles of am "empty" sac below. He knew what the serum was doing to the otter and he embraced it. He squirmed forward as much as he could, despite being weighed down by the tremendous amounts of liquids inside of him. He playfully flexed, stretching the cock flesh even more, his outline along the bottom-side of that cock seeming to simply grow and bulge.

Bobert gasped and moaned at the straining of his cock, but he worked through it and pushed harder over Tachi's waist. He was half-way into the giant dick, now, while the otter leaned over the bulges his slut made. Despite the promise of a huge meal, his hunger was growing ever more ravenous. The billowing steam was drowned out by the heavy churns coming from that massive sac, sliding along the moist floor with his arching.

Tachi was adjusted while he was tugged forward, moved by the walls to bring his legs behind him. His huge, black cock was being engulfed by the bigger one, shoving along the bottom-side and making an even bigger bulge below. His legs kicked somewhat, pressing along the floor and even scratching into it to slip deeper. Precum was splashing around him, if only to lube up the walls to pull him in more easily.

The wolf's head would push through the ring separating that sac. A wave of cum met him, splattering into his face while he was pulled deeper, groaning while his shoulders inched afterward. Eventually, his gigantic pecs would push through, starting to bloat that sac further and further, stretching it along the wooden floor as the wolf fed it. He was up to his knees in the cock, and eventually only his feet were hanging down from the slit.

After Tachi's belly popped through, Bobert managed to lift his cock upward, leaning backward far enough to send the leverage through the huge, hungry meat log. The wolf's waist pushed through, followed by his gigantic cock, and his feet slipped down past the dark helmet of the otter's member. The rippling continued while precum belched up from the slit, greedily sucking the monstrous wolf down to feed those great bulges to that sac.

Tachi shuddered at the hard, heated rippling of the cock walls around him. He was steadily swallowed as if being pulled down an actual, sticky throat. The bulges of his form collected downward, pooling that sac out more and more with his body until, at last, his feet dipped in, launching him fully into the small sea of otter cum. He sputtered, panting heavily while he settled there, still unable to move from his previous bloating.

Bobert's body quivered from the strain. He stroked gently along his huge member as it pressed back down like relaxed elastic, going back to a more "manageable" size. Thanks to the serum, however, there wasn't much that could be done from the size it had gained. He let out shaky huffs of pleasure, reaching down to rub along the sac that was now bigger than his body. His paws slid through the fur and over the beastly wolf inside, a bigger grin coming over his face.

"Damn, I actually did it," Bobert panted, leaning into his sac as he trailed his paw over the muzzle of his slut, feeling Tachi press out against it.

"Yes sir. I hope you enjoy what comes next," the wolf murmured, although muffled through the musky flesh.

"Of course I will. I hope you do, too," Bobert murmured, leaning his head forward to kiss against the covered muzzle.

If anything, the gurgles only grew louder. Whatever the serum was, it didn't waste time. Bobert moaned as he felt his sac churning and squeezing, practically gripping the wolf inside as he squirmed. His body tensed again, going rigid while he rolled against the churning sac, huffing in delight and pleasure. He squeezed where he could, watching his gigantic sac work along his slut.

"O-oh God... it feels... so good, slut..." the otter gasped.

The wolf was squirming, gasping and moaning inside. His cock surged, precum splattering and adding to the waves of white that were splashing over him. Pleasure was rushing through him as his strength was sapped, causing him to slack and get weaker inside the squeezing walls. It was working into his hair, fur, and flesh, and the warmth engulfed him and caused him to shiver in delight.

"Y-yes sir... nngh... it does..." the wolf moaned inside, though his deep voice was lessening bit by bit.

After a few more moments of working over his slut, Bobert went rigid once more. His body tensed while his eyes widened, his heart jumping against his chest. He gripped over it, feeling his blood rushing all over, leaving his face to redden. Veins rose along the otter's groin, travelling upward to where his chest pushed out as well. The thick tubes began to appear along his arms and thighs as well, leaving him to shiver harder.

"O-oh God... fuck, slut... I feel you... all over..." Bobert whined, leaning over his gurgling sac, feeling the form within getting softer.

There was an audible throb that shot through the otter's body. It was followed by another, and another, soon going along with the male's heartbeat. It caused him to tense further, but the heat was counteracting the tension. As the loud pulsing continued, the otter's body began to flex. His body flexed all over, involuntarily or not. His thighs were pressing apart from the sudden growth down below, visibly shifting beneath the thick pelt.

Bobert continued his non-stop groaning, though his voice was starting to drop. First, it was only a slight octave, but as his pecs began to push outward, it dropped to a bass that vibrated the benches in the sauna. He bared his teeth while his shoulders flared--his left deltoid shoved out, then his right, evening out until his neck thickened. The mounds were already brushing his chin while his form bulked all over.

Tachi was shuddering inside of that sac. His form had taken on a white hue, quite a bit of his hair having dripped and melted away to reveal a softening body below. Liquid dripped all over, but it was hard to tell if it was from the cum he was in or if it was his own form diminishing. His muscles went lax while he submitted to his master otter, gurgling a few more times before he felt the squeezes molding him into irregular shapes. He was being balled up, kneaded down, and stretched along like putty.

"Nnnngh... bye for now, slut..." Bobert's deep voice rang out through the wooden room, rolling his growing hips down against the smoothing bulges.

There were a few more gurgles before it quieted. The great bulges that were once the wolf were now just smooth, gigantic nuts hanging beneath the growing otter. After it finished, the pulsing only grew louder and more intense. Bobert snarled and gripped around his cock, flexing his arms as they strained and rippled. There were thick, deep snaps that rang out from the straining body, the very bones of the otter even growing in size, repositioning bit by bit to further support the straining sinew.

Bobert practically roared as his back pushed out, having to arch from the swelling muscle as his arms followed suit, widening and pushing themselves away from the growing torso. His pecs continued surging while his nipples fattened, sweat dripping copiously from the thick flesh. The otter's paws were even popping thicker, claws sharpening and lengthening along the tips. His forearms were showing thick cords of muscle, continuously rippling with his movements.

Precum was gushing from his gigantic cock. With his lengthening legs, those huge balls were slowly lifting from the floor while he arched. His dick slapped along the wooden wall, gushing up along while his thighs and calves widened, creaks and groans sounding louder, although deeper, with the thickness that Bobert was gaining. He lifted an arm from the wall, watching through wincing eyelids as he intentionally flexed this time.

The bicep peaked higher and higher, bloating like a small mountain over the stretching arm. His forearm even widened with his movements, being at least a few feet around. He grinned a toothy smirk while he watched, the sight causing him to groan louder and gush more precum along the log-embedded walls. He arched and humped, starting to grunt and snort like the beast he was becoming.

Along with the growing muscle, an itch developed along his body. He reached up and scratched along his chin while brown hair sprouted, bushing slowly into a stubble. It soon bushed out into a beard, moving along his jawline while his brown headfur lengthened, getting longer and draping over his face while the sweat dripped down. Between his pecs, more hair sprouted. Brown began to cover the creamy fur, similar to how Tachi's had. It blanketed and bushed up down along his bricking abs.

The brown hair sprouted through the cream and tan fur of the otter. He continued to scratch in random places with one paw while his other stroked and pumped his gigantic cock, grunting while his underarms grew itchy as well. The hair sprouted into thick bushes beneath the now-gigantic arms while his groin gained pubic fur, everything bushing thicker while he gained the wolf's masculinity as well. His musk overtook the entirety of the room, having drowned out all four of the previous men's scents.

Along with the brown hair, there were a few blond strands that were sprouting along his body. It appeared as if Bobert was gaining a few slight highlights amidst the brown of his head, a few small follicles sprouting along that bush of chest hair. It wasn't as apparent as the brown hair, but there were definitely more hints of the wolf on Bobert's body.

The growth finally began to taper off while he pumped his cock, snorting like the beast he had become. Precum was gushing so hard that it hit the ceiling, but he began to work himself over toward the door in the process. With his bigger foot, he scooted away the towel he had laid down earlier, knowing that he would likely fill the wooden room with his slut had it remained there. He didn't want to have to swim at the moment.

Lifting himself up, the otter's balls were lifted high from the floor with his increased height. He flared his huge limbs and gripped around his cock, humping into it while the wide sac sloshed and gurgled beneath. There was nothing left of the wolf anymore, only steaming otter cum to erupt all over. It wouldn't be long from the sheer pleasure of his growth. His cock was already growing harder while his balls clenched.

With a final roar from the monstrous otter, the gurgling grew to a peak. The stomach of that gigantic cock bloated out, straining and stretching with the on-coming load, working its way up until it reached the tip. Spreading widely, that thick slit erupted with white. It hit the ceiling and splintered the wood before it coated it in mere seconds. Gallons gushed from that gigantic cock, hitting the ceiling over and over again before splattering back to the floor with heavy, wet splotches and plops.

The waves of otter seed were already rising along the walls of the sauna. It was rising up his ankles and his thick bull-like calves, panting heavily through his moans and snarls. It splattered back against his chest and cement block abs, reaching down to rub the musky liquid into his thick pelt and hair. He was clenching and rippling with all of his muscles, arching along the wall while his calves were covered, rising up to his thighs.

"Good slut... nnngh... My huge... powerful slut..." Bobert growled, his voice causing ripples in the steamy cum below.

The wooden door was steadily creaking with the increasing pressure of the flood of cum. It wasn't stopping. Bobert was up to his waist in white before the door popped from its latch, swinging open to release the liquid that had built up. It rushed into the gym and coated many of the exercise machines as well as the patrons using them. The otter's roars were less than the wolf's were, but it still caused many of the patrons to shudder.

The cum was flooding throughout the area with Bobert's intense orgasm, but it couldn't last forever. After a few more minutes of constant gushing, it slacked, getting less and less to a slight dribble while his big tongue trailed over the fat, black cockhead. He panted, slowly drawing himself from the wall as his cock slapped over his car-sized nuts, smirking and reaching down while he brushed a few of his longer, brown locks back.

"Good slut, I'll keep you close," Bobert said again, rubbing over his massive member as it slacked further, trickling the last few spurts of semen.

He stepped through the open doorway, having to bend over and squeeze to the side. After he popped out, he looked down at the patrons who dripped with white, chuckling deeply before he shut the sauna door back. Bobert rolled his broad shoulders, a few thick pops coming from them before flexing his pecs, caressing them and tweaking a nipple that easily filled his entire paw. He bounced them, bringing his other paw up to sink into the other mound.

"Mmm... an entire gym of sluts, all for me," Bobert growled, walking toward the lobby of the gym, sitting in the wolf's huge chair while he leaned back. After leaning back, the otter lifted his feet and plopped his large, padded soles on the mahogany desk.

There was a new gym owner in town.
