Zeus stood in the doorway with a stern look on his face. His right hand wrapped around the knot of his sharp red tie, adjusting the lay of it across his broad chest. A black suit coat with thin yellow pinstripes hung around his shoulders, framing the muscular torso of the large pegasus, whose eartips almost grazed the door jamb above him. His long, gray neck turned side to side, allowing him to survey the situation in the research laboratory he'd been called to to deal with an ongoing liability issue. As a lawyer for SynTech, the winged stallion was no stranger to unusual disturbances among the thousands of researchers, assistants, scientists, support staff, and security that worked in or under SynTech Tower.

The pegasus's wings fluttered outwards briefly before resettling around his shoulders. They pressed through the back of his shirt and coat using specially reinforced slots hemmed into the fabric. A dark gray tail flicked across his wide thighs, brushing all the way down to the upper part of his wide onyx hooves. The tail was streaked with bands of gold, similar to the gold running through his dark gray mane and hair. His mane hung like silk across his smooth hide, soft and shiny in the light of the hallway behind him. With a professional eye, the SynTech lawyer tightened his grip on his briefcase with his other hand and strode forward. He ignored the slick and deep puddles of sticky white cum, and the unbearably hot and moist, musky atmosphere in the room. The door remaining open didn't help much to relieve the overwhelming scent filling the air. His nostrils flared and the long, thick bulge traveling down the right leg of his pinstriped suit pants twitched despite himself.

"Mercury?" he asked, eyes narrowing a bit as he watched the target of his gaze continue on with her activities. He set his briefcase down on the single table still upright in the room and hit the latch with a finger. The high-tech suitcase popped open, revealing a screen, keyboard, and various office supplies like paper and pens. The screen flashed on as the pegasus continued speaking. "Mind if I have a word?"

Against the far wall of the room, a good ten feet or so from where the stallion waited for a response, a bright yellow mare lifted her eyes. The pale pink of her irises matched the color of her swollen nipples, as well as the enormous maleness stretching from her thighs. Her plump, full yellow hide was taut and swollen, adding inches to her hips and belly and breasts, amplifying her already curvy figure. She leaned forward, both hands wrapping around and squeezing down into the base of her enormous erection, which stretched a good four feet into the air in front of her, the tip rising from the ground to the same height as her head. The mare's muzzle opened slowly and bands of gooey liquid stretched between her lips as a long groan escaped. Drips of goo fell from her elbows as well and ran down her breasts, beading and rolling over until they were reabsorbed back into her belly. Her hips shifted, pumping forward as the base of her massive arousal shoved her equally impressive bright yellow balls flat to the floor between her legs, which had to spread to accommodate their weight. From within the immense sac, Zeus could see clear signs of wriggling as arms, legs, and occasionally faces shoved outwards against the straining, taut yellow hide.

The pegasus tapped a few fingers at the keyboard in the briefcase next to him, though his eyes remained locked on the mare until he pulled up the information he desired.

"Well, Ms. Mercury Drop," he said, "it seems you're a part-timer at the Pinnacle Club as a hostess and waitress. According to this, you volunteered for an experimental research program designed to amplify certain characteristics in order to better serve your customers."

The stallion paused and glanced up at the gooey, dripping mare. Her breasts spread around the girth of her cock as she pulled the huge arousal upwards, and at the tip, the pair of furry feet sticking out of the end disappeared. The mare leaned back onto her rump, groaning and gasping, as a large bulge traveled down the enormous shaft and into the churning, round sac. As Zeus watched, a few bulges and shifting movements still pushed on the enormous balls from the inside. The stallion grabbed a form next and made a few ticks, then signed at the bottom with a flourish and stowed it back inside the briefcase, which snapped shut and pulled all of the contents back in as he clicked the button on the handle. The stallion's muzzle pulled into a smirk as he moved his large gray hands to his suit coat.

"After the experiment was a complete success, you went a little overboard with your celebrations, but nobody's perfect," the pegasus grunted. His coat draped over the suitcase, followed by his shirt and tie, then his pants. The mare's eyes widened as she watched him approach, a lustful look burning in her pale pink eyes. "Still, we've got to make sure we keep any potential liabilities in check."

The stallion's massive, flaccid pink maleness dropped across Mercury's head and muzzle. The mare moaned as she squeezed at her maleness with her hands, working the bulge of the furry otter inside down the length to join the rest of her "customers" in her sloshing, goo-filled balls. Mercury's long muzzle turned to the side, lips spreading wide, automatically opening, as her gooey body deformed under the heavy weight of the pegasus shaft draping over her muzzle and head. Her eyes closed as she tasted the pegasus stallion's skin, and the big male's hoof scraped on the ground as he realized she was just as warm and tight as she appeared. Her dripping body shoved forward, eager and impatient, throat bulging with a soft stallion shaft. The length stretched, still soft, pulled down into her belly as her muzzle shoved up against the base. Zeus closed his eyes and leaned forward, one hand bracing his broad, muscular arm against the wall, while his other wrapped around the mare's soft head, squeezing her deeper, shoving her forward and flattening her gooey body against his crotch.

"This experiment was supposed to help with macro week at the Pinnacle? I can see why they'd aim for that," the stallion grunted, his tone changing from the business-like monotone of before to a more sensual, deeper sound. Mercury's throat stretched as the pegasus cock suckled deep down began to fill out and grow, hardening fast in the rippling confines of the goo-mare's throat, every inch of the fat stallion-shaft outlined and squeezed and showing through her stretchy, gooey muzzle and neck. Zeus closed his eyes and tipped his head back, hips pushed forward, keeping his musky, round balls draped over the mare's soft yellow chin. "I bet you'd make for a real proper liability claim if you grew a hundred feet tall. Nnnff..."

Within a few short minutes, with Zeus having to do very little, the eager mare's throat pulled the first few drops of musky, salty pre-cum from his growing length. He wasn't even fully hard by the time he felt the first jerk and gush of warmth spill into her dripping figure. Almost immediately, the pony's breasts swelled. The pink nipples hardened as she suckled all the more eagerly, each drop of thick pegasus seed causing her to grow a bit more, as her gooey body converted the musky essence into even more drippy, horny goo-pony flesh. The churning in her sac escalated as she recycled the males she'd already milked to the last drop, and Zeus had no doubt she fully intended to do the same to him once she was done extracting every ounce she could.

The pegasus grinned as his fat, dark gray sac swelled with arousal. The pale yellow pony's distended jaw dripped with her own goo and his seed as he flexed his cock, giving her a taste of just how productive the oversized stallion could be. Her breasts flattened to the floor around either side of her maleness as she fell forward, dragged onto her hands and knees by the weight. The yellow mare's huge maleness squeezed right through her immense tits, pulsing and shooting between the stallion's legs as he leaned forward, squeezing his hips until he got just the right amount of pressure on his long, thick horsecock. He could feel her scraping and squeezing and grinding around every little inch of his maleness, especially the flared tip and fat medial ring. The stallion's hips clenched as he pushed forward again, thrusting now, grinding against her as she groaned and gurgled and sloshed. He stared down past the top of her head, watching as her rump twitched and flexed, each spurt of his warm pre-cum fueling the size of her ample backside. The gooey pony's tail was lifted, hips shifting as her legs spread to either side of her massive balls, which were even fuller and rounder and bigger than her wide hips and glutes.

Zeus dragged his hips back, pulling more than half of his impressive length from the goo-mare's muzzle. Mercury's eyes opened, watching with eagerness as more and more of the fat, warm length came into view past her dripping muzzle, leaving a stream of thick white seed to puddle around her equally drippy tongue. The mare's breasts swelled larger yet as her body absorbed more and more of the muscular stallion's essence. Zeus didn't seem to mind as he nonchalantly teased the tip of his thickness across the yellow mare's lips. His gray hand squeezed around the base of his pink length, causing the veins to pulse as a few ropes of pre-cum splattered across Mercury's yellow muzzle. They were pulled in and absorbed almost immediately, making her lips fatten up significantly. The lawyer grunted, enjoying very much how the mare's caress felt around his flexing tip as she kissed her way along the urethra. Each blast of seed rolling down her sticky hair and shoulders was absorbed into her skin within moments, soon doubling the weight and heft of her massive breasts, to the point they flattened over her thighs and the floor in front her. The mare's light pink shaft speared between the enormous tits, spreading them apart as the huge cock, now thicker than her own curvy hips, throbbed in the air behind Zeus's back, reaching nearly up to his head as it pulsed between his thighs. The stallion's hooves scooted forward, pushing against her swollen sac, eliciting a gurgling rumble from the mare as she closed her eyes and shuddered. The pegasus closed his eyes as he leaned forward, his hard and taut thighs shoving against the massive breasts spilling from Mercury's chest as he struggled to keep his thickness within reach of her moist, warm lips.

The mare sagged, beads of goo rolling down her body irregularly, but often, forming and reabsorbing as she shuddered and wiggled and jostled, her entire yellow frame bloating as the churning noises in her fat balls amplified. The stallion pulled himself away from her front, despite her gasps and moans, and walked around behind the mare. The weight of her breasts pulled her forward, tipping her so that she was laying across the huge stallion cock growing further away from her by the moment, while her legs spread around the nearly four-foot-tall yellow sac between her thighs and knees, which was pulled up hard and round and dense to the touch, showing hardly any movement now as her enormous, swollen maleness flexed with more urgent need. Shifting his hooves in between her plump, thick thighs and her enormous balls, the muscular stallion dropped his massive length along her backside. The plus-sized pegasus smirked as he felt the broad, wide maleness splat into the gooey mare's rump cheeks. It sank in until the mare's overgrown ass wrapped entirely around the achingly hard, flared pegasus dick, hiding much of the veined maleness from view, before Zeus's hips pushed forward, flexing his cock up and out of the warm embrace. Zeus brought his hands down, smacking them into the sides of Mercury's hips. She did her best to wiggle her hips and shove backwards against the hung pegasus, to feel more of his incredible thighs strain against her plump hips, but the weight of her breasts kept her chest pinned to the floor, unable to do more than wiggle as her legs and arms dangled far from the floor.

Mercury stretched open her muzzle, but the rapidly dripping and stretching bands of goo revealed little of the inside, though the mare's turgid length erupted, accompanied by wet groans and gasps. Zeus didn't stop shoving forward, grinding deeper between her clenching, soft, gooey cheeks, which rippled and tugged at every little bit of his sensitive, fully-flared stallionhood. Filling and stretching the gooey body of the mare until his thighs smacked into her rump cheeks, he could see her belly stretching to the sides, pulling her flexible "skin" tight down her sides and back as she inflated even larger. She wiggled desperately, clearly needing and wanting more even though her body began to show signs of strain in her growing figure. The mare rolled forward, and Mercury's eyes flashed, tongue flopping out, a stream of drool catching on the floor as her hips were suddenly pulled backwards. The big, powerful pegasus grit his teeth, eyes closing as he shoved the gooey hips back and forth, dragging Mercury across his long and powerful thickness. Thrust, splurt, thrust, spurt, with each timed stroke ensuring the lawyer deposited his virile, potent seed far deep into the softening figure beneath him. Mercury's needy cries followed another huge blast of seed from her vastly grown shaft, which created a splatter more than ten feet across on the other side of the room, and after a few particularly deep, rough thrusts from the pegasus, half a dozen cum-covered lumps of dark brown fur fired out the end. Each one landed on the far wall and slowly slid down until they created a pile of wiggling, groaning, gooey otter bodies on the floor. The soaked figures of the otters were significantly shrunken down, the smallest only three feet tall, though none appeared to mind as they groped at their bodies and arousals, cumming uncontrollably as the gooey mare's seed dripped from their open muzzles and backsides.

"Well, that makes things easier," the stallion grunted through his broad, flat teeth. "Now that they're out of the way..."

The mare's plaintive cries escalated. Zeus's wide hips pumped hard, flattening the goo-mare's entire lower body down into her fat balls, only slightly smaller now that her snacks were forcefully ejected. His nostrils flared, mane waving back and forth as he flexed his chest and arms, using more of his power to keep his huge shaft thrusting. Mercury's breasts, still growing, continued to spread across the floor. Her slender arms stretched outwards across the dripping orbs, scraping and merging into the flesh as she was unable to reach more than halfway down the swell. Both large nipples were out of few, flattened into the floor and scraping back and forth as the pegasus stallion grit his teeth and pumped harder yet, spreading the flexible goo-mare open wider and wider, until her enormous rump cheeks spread rippled around the sides of his hips like she was trying to surround him. The stallion's enormous sac flung forward and back between his legs, slapping down into the warm balls billowing between the mare's spread legs.

The pegasus stretched his wings out behind him suddenly. The large wingspan filled the room as he flapped and beat his shoulder muscles. Huge gusts of wind whipped behind him, forcing the pegasus forward harder than if he'd just used his grip and hips to get the job done. Mercury's head arched, muzzle dripping open as her eyes widened, bulging outwards. Mercury's skin turned transparent in splotches across her belly and breasts as Zeus flexed harder than ever. His wings sent huge gusts backwards, propelling his massive length into Mercury's bloated, taut rump cheeks until they clapped against each other around the stallion's backside, surrounding his muscular midsection completely. The mare's belly and breasts surged outwards, inflating like a water balloon as the stallion's whinny of pleasure rocketed from his throat. Head back, mane tossing, Zeus dropped his professional mannerisms, and instead stamped his hooves and pawed at the mare's slender shoulder while filling her body with long-deprived orgasm. The muscular pegasus fired a load unlike anything she expected. Having already taken unknown gallons of what turned out to be mere pre-cum, Mercury's eyes rolled into the back of her head as her cock switched from rapid pulses of seed to a single steady stream. Her toes curled, draping over her pulsing sac, as the dribbling and dripping bits of yellow rolling down her body multiplied along with her gasps and moans for more.

The pegasus shuddered as he released, huge nuts flopping against the back of the mare's sticky, plump backside. His fingers dug in as her body got softer and more flexible the larger it expanded. Soon, as Zeus felt a second tide of seed about to erupt into the warm and rippling mass of goo, her pale yellow body turned even more see-through, losing opaqueness rapidly. The stallion's massive pink cock appeared first as a shadowy outline, then as a visible dark red log, angry and throbbing, flexing and kicking deep inside the shifting sprays of thick white cum, visible jets of musky horse seed flooding outwards with every heartbeat before being absorbed. The cycle continued as Zeus leaned over, hips pumping and wings beating, hooves scraping on the floor as he clenched his belly and used his core to grind himself against the mare. He grinned, teeth bared in a frenzied, lustful smile.

White pools of horse jizz formed in the mare's breasts, suspended in the nearly completely clear flesh of her gooey form. Unable to convert the rapidly escalating amount of cum pumping from Zeus's arousal, Mercury's body stored it instead, and her growth increased exponentially. Streams of cum drained from her huge cock, fat nipples, and open muzzle as the last few bands of yellow rippled through her body, swollen to eight or nine times her original width, spunked up with so much cum her very bodily integrity came under attack. Her massive hips wrapped around the stallion completely, holding him in place as he wriggled between them. Her breasts filled the room from wall to wall, shoving upturned furniture and equipment out of the way as they jostled and bloated. The mare's enormous balls squeezed between Zeus's muscular legs so that his knees and calves applied constant pressure around the base of the immense pink cock, tighter than any cock ring. The gooey length slapped against the floor in front of Zeus and Mercury, wild and out of control; the tip scraped over the far wall of the room as the length, which was softening and losing integrity just like the rest of her, bent into the corner so that the flared horsecock pointed upwards and blasted the ceiling. Beneath the length, the pile of half a dozen shrunken, groaning otters wriggled and moved, realizing their fun wasn't quite over as they dug their webbed paws against the stalk, shoving and pushing against the gooey, semi-solid maleness.

Mercury's eyes widened as her enormous body throbbed one last time. The otters wrapping themselves around her hyper-sized maleness squeaked with surprise as they felt the tension go out from underneath them. The mare's eyes closed as her head suddenly collapsed into her shoulders. The gooey features melted into her breasts, which melted into her torso and belly. Zeus grunted, still thrusting even as he felt the mare dripping from his cock and through his fingers like warm, rubbery candle wax. Her yellow color returned somewhat as her body spread, flattening, a gush of musky seed expelling from all sides as, like a piece of rubber on a hot car dashboard, she melted into a puddle of uncontrolled lust.

The stallion snorted, only half-satisfied. His massive shaft bucked and he was forced to grab it with both paws as the puddly mess of the mare's body spilled around his ankles and hooves, still warm and rippling. The pegasus grinned as he used both hands to force his cock down, until the dribbling, pulsing streams of seed aimed into the yellow puddle.

"And until you're able to keep control of yourself, I'll be in charge of your safety, of course," the stallion grunted. "We'll get your signature... nnnfffghh... later!"

The stallion's cock flexed in his hands, but he tightened up his shoulders and leaned forward, keeping his tip buried into the puddle of yellow mare-goo. His cock flexed again, and the puddle suddenly shrank. A round bulge formed in the tip of his cock that traveled swiftly down his huge length as the rest of the goo followed, instinctively keeping together as much as possible. The stallion's huge balls dropped down to the floor and flattened over the waves of thick seed as they dragged the goo down into what the big, muscular male considered a safe place for the hungry, horny goo-mare. For now. He leaned back, hands stroking his magnificent length as it bobbed up into the air. The otters, recently shrunken, recovered enough to realize what had happened and crowded around the pegasus, none coming past his hips. As Zeus felt the gooey mare ripple and wriggle around inside his bulging, shifting balls, the pegasus finally relaxed a little and smirked at the otters as their webbed hands stroked along his length.

Well, they did want to thank him properly for the assist, and how could he say no to a request from a client? The stallion licked his lips as he swung his massive stallionhood towards the nearest otter, both hands around the base. He merely had to snort once, nostrils flaring, hoof scraping, and the otter practically dove into his tip. The wriggling, squeaking male's slender head and shoulders stretched the pegasus wider than the gooey, liquified mare did, and he had to widen his stance as his massive, inflated, goo-filled sac jiggled rapidly with anticipation. His maleness bucked, lifting upwards, carrying the otter with it so that the small male's legs and feet pointed towards the cum-covered ceiling. The pegasus leaned back, his huge dark gray sac acting as a counterweight, and stroked his hands down his length as the rest of the otters shoved into his legs and nuts, churring and stroking and squeezing at him.

The stallion's eyes closed as he moved his palm across his shifting urethra, feeling the outline of the otter's chest and belly and cock push back against him as he dragged the male down to join the mare. The otter's head was halfway to his base, his feet having just disappeared into the broad, flat arousal, when Zeus grabbed the next as the remaining four worshipped at his enormous sac.

"Don't worry," he groaned, as his enormous orbs rippled, stretching outwards in all directions as the gooey mare helped drag the otter down and surround him inside his tight, heavy balls, "I'll let all of you out once I'm done with the... nnffff... paperwork!"

* * *

"Mr. Zeus, message for you, sir."

The stallion paused mid-stride, calm and professional as ever. The stallion's suit jacket hung immaculately from his shoulders, his mane was brushed until it gleamed, and his tie stretched down his button-up shirt, not a wrinkle in sight. The wide-pointed tip of the red tight lay flat across the huge base of Zeus's maleness, which draped from his hips casually, effortlessly, despite being nearly three feet long. It pointed almost straight out, held aloft by his immense balls. The undersides of his roiling, churning sac hovered inches from the floor, hanging from his wide hips down past his knees and calves, obscuring almost his entire lower half thanks to the girth of the glistening, rippling orbs. They pulled downwards like water balloons hanging from a garden faucet, all the weight of the squirming otters and sentient mare-goo puddling into the middle and giving the stallion a pair of glistening, jaw-dropping eggs. There was no possible way he could squeeze himself into a pair of pants, so the stallion chose, after taking care of the liability issue down in the lab earlier, to simply go without, rather than waste time attempting to jury rig a solution. Besides, judging from the way the stallion's nostrils flared and his facial features tightened every so often, trying to wrap his immenseness up would be a poor choice before long anyways. Dozens of people squeezed by down the hallway, many panting and staring and sniffing as the big winged horse's musk followed after him, along with plenty of dribbles of pre-cum. The stallion nodded and greeted the people he knew even as he flattened them into the walls with his musky sac or smothered them in the half-hard glistening pink length of prime, begging-for-attention horsecock. Zeus kept his wings tucked up neatly behind him even as his swollen balls scraped against three sides of the hallway at once. A team of custodians was already hard at work down at the other end of the hall cleaning up the messes he left behind. Zeus's round and toned rump cheeks flexed as he turned to the side, which forced his enormous cock to slap against the wall and scrape down the white paint, leaving a second coat of white behind as he looked at who spoke to him.

"Ah, thank you, Terrence," the stallion said, accepting the slip of paper from the junior assistant, a white and brown clydesdale with a muscular build, though much smaller than the pegasus overall.

The clydesdale's eyes dropped, staring hungrily at the massive arousal swaying from the other stallion's hips, lewd and obscene and completely irresistible.

"Anything else I can help you with, Terrence?" Zeus asked. He was used to the looks of shock and lust. In fact, he enjoyed being able to make people do a double take. It was part of the job. The clydesdale's pants swelled as the pegasus shifted the weight of his body from one hoof to the other, making his entire sac and shaft swing to the side. Signs of internal wriggling and a muffled assortment of squeaks and moans followed from his balls, which continued to gradually, slowly, achingly stretch and fill even as he spoke. "Perhaps you'd like some on-the-job training?"

The clydesdale's eyes went even wider and he nodded furiously, practically drooling as he watched the massive stallion's balls.

"In that case, let me show you my favorite containment techniques for when you come across a situation that requires immediate liability remediation," Zeus said, his maleness lifting from the swollen, round gray sac. Powerful thighs flexed, shoving the incredible weight of the swollen balls forward one step at a time, shifting the bulging and rippling orbs side to side with his legs and hooves each step he took. The lawyer advanced on the clydesdale, pinning the stallion against the wall with his upturned length, while his enormous sac squeezed against the wall in front of him, spreading the clydesdale's legs wide to the side. The powerful pegasus held his ground, meanwhile, forcing his swollen orbs to spread to the sides and out back between his black hooves and muscular calves. The motion from within Zeus's magnificent balls increased substantially as the pegasus rose up thicker, harder, and fatter from tip to base. Zeus lifted his dark gray fingers to his red tie and smirked as the stallion's pants not only tented into the heat of Zeus's balls, but dripped from his thigh all the way down to where the silky white fetlocks draped from the assistant's suit pants over the wide, dark brown hooves. The clydesdale's hips shuddered as his nostrils flared, unable to stop the rush of lust as he caressed the fat veins feeding the stalk and broad flare of the tip with his fingers.

"And don't worry - if you're not out by the end of the day, I'll put in the overtime request myself. Heh heh heh..."

The end
