A very tauric transformation
This is the second TF story I've ever written! It was crafted with the help of a friend, and I hope you enjoy it. Feedback is greatly appreciated!(Apologies if formatting is weird at the moment, I wrote this on my phone. I'll edit it to be more tradition later)
Slick: me

************************************************
"Dude I got in" Slick said as he walked in the door, holding a small paper bag. The cabbit had always been a bit of a size queen, and desperately wanted to be bigger downstairs, a lot bigger. He'd applied to take part in a virility enhancement drug trial in the hopes of becoming egregiously endowed.
"Dude no way!" replied Luka from the couch, "when are you gonna take the pills?"
"Right now, I can't wait to become a super hung stud."
Slick fished the pills out of the bag, opened the bottle, and dumped the whole thing into his mouth, washing the pills down with a big swig of water.
"Uhhhhh, dude I don't think you're supposed to take all of them at once" said Luka with considerable concern. Slick, however, had a devilish grin on his face.
"If one a day is supposed to make me a little bigger, then all of them at once should make me huge. Ohhhhh fuck I can feel it starting already"
The Cabbit's arms started to bulge with new muscle, his neck thickening as his chest became broader. His shirt tore open exposing an emerging 6 pack. The pressure in his pants was incredible, and he ripped them off to free the beast that was quickly growing inside.
He could see his dick was steadily expanding along with his balls, which ached as they quickly filled the space between his thighs, forcing his legs apart as they sloshed and churned, filling with more and more cum. He suddenly felt a weird pinch at the bottom of his torso, and looked down to see a new, second pair of legs growing out from his hips.
"Ohh fuck dude what are those?" he asked
"Dude I think you're turning into a taur. That's so cool!" replied Luka.
While his new forelegs grew, Slick fell to the ground as his original pair started moving backwards, along with his genitalia as his torso lengthened behind him. Within moments, he was standing again, only this time on 4 legs.
The growth of his tauric torso had given him more space between his thighs, and his already oversized endowment took full advantage. He howled as his balls suddenly expanded further, growing until they rested lightly on the floor, so large that they brushed against his thighs whenever he moved. They roiled as they sagged with their heavy load of spooge. His dick surged forward, knot expanding to match, until it reached all the way between his forelegs, drooling with a veritable river of precum.
Slick raised a foreleg and started pawing at his cock while Luka watched, drooling. The room was starting to fill with an intense, salty musk that was almost hypnotizing to Luka. He slowly got up and started to walk over to Slick, mesmerized by the pheromones he was emitting.
Slick meanwhile, experienced a few more odd sensations simultaneously. He felt two new points of pleasure, one where he might expect it, directly in front of his dick, but the other was strange, it was inside his mouth.
His mouth filled with a salty, musky fluid and his tongue was suddenly extremely sensitive. It started pushing past his lips as it drooled, and as it became visible to him, he could see he now had a cock for a tongue. It dripped pre down his chin and onto his chest as its tip honed into a point, gaining a series of ridges on it's underside, and a knot that locked it outside of Slicks mouth, for the time being at least.
Slick could only breath through his nose now, and he got a concentrated dose of his own musk, moaning as it supercharged his already raging lust. He could feel something sliding along his dick, and quickly realized he had grown another, directly in front of his original, complete with its own sheath. Between his hind legs he could feel an extra set of balls sliding to the ground, giving him a full double set of male equipment.
While Slick was enjoying all the new changes to his body, Luka had been slowly approaching, stripping as he walked, entranced by Slick's musk. His cock was hard as steel and dripping as he approached Slick, walking around to his rear and stuffing his face between his rearmost set of balls. As he took a big huff of Slick's musk right from the source, he came a little. He hefted each ball individually, they felt so dense and he could feel and hear them slosh and churn with dozens of gallons of cum. He slid underneath the ball sack, stuffing his muzzle between all 4 and taking another huge whiff. At this point he was completely hypnotized, but he needed more. He reached out from under Slick's balls and grabbed one of his knots, using it to pull himself out from under his balls, so he could grind his whole body against Slick's cocks. He climbed on top of the lower one, sandwiching himself between the two cocks and humping them, eliciting a startled moan from Slick. As the cocks soaked him from head to toe in pre, he started slurping it up. After he drank what felt like a gallon, his tongue started to tingle and swell. A hole opened up at the tip that quickly started to drool pre of its own.
Within moments, Luka had a brand new cocktongue of his own, pointy and knotted like Slick's, but lacking the ridges. He suddenly felt the desperate need to stick it in something.
He climbed out from between Slick's cocks, and rose to meet his face. He slid his cocktongue along Slick's and wrapped his paws around both, frosting them together. As he approached his climax, he moaned as he began to slip his tongue into Slick's mouth, and slip slicks tongue into his in turn. They slid slowly together until their knots were squished together, straining until they were both knotted in each other's mouths, tips down each other's throats.
They both exploded, each dumping what felt like gallons directly into each other's stomachs, as their (relatively) regularly placed cocks dumped their loads on each other. Luka's sizeable but comparatively diminutive load was lost amongst Slick's tsunami of spunk, blasting Luka until they were completely soaked from head to toe in spooge.
As soon as they finished, their knots softened enough to separate from each other, but neither felt satisfied.
Slick felt his balls immediately begin to churn and slosh with a new load of cum, and Luka felt his begin to swell between his thighs as his dick grew.
Luka managed to moan out "I need you inside me" around his still deflating cocktongue, and Slick gladly obliged. He rolled onto his back and helped Luka slide their quickly expanding pucker over his lower dick, using his forelegs to push him down, inch by inch until his stomach started pushing out from the sheer size of it.
Slick rolled back onto his legs and started thrusting in and out of Luka, grinding his upper dick against Lukas upper body. Luka moaned as his prostate was obliterated by Slick's person-sized tool.
As he was speared by Slick, Luka felt a change in his crotch. A kind of burrowing sensation below his stomach, that quickly reached the surface, splitting open into a plump, swollen, wet spade behind his balls. He screamed as an unbelievably sensitive point of pleasure opened at the front of his slit, moaning as his balls slapped into it with each of Slick's mighty thrusts.
Slick could smell the change in Luka's scent and felt a change in himself. He felt a intense need to breed, to stick his cocks in two holes at once, to empty his balls over and over until he could no longer move. He quickly pulled his lower dick out of Luka's ass and thrust it into his brand new pussy, spearing his upper dick into Luka's ass at the same time.
Luka's body spread and grew around Slick's dicks, his torso expanding and lengthening to accommodate his full length. As he too grew a pair of forelegs, Slick wrapped his own around Luka's mid-hips to get better leverage, burying his muzzle in Luka's neck, inhaling his new, enticing musk. Slick himself felt a yawning cavity open under his tail, his asshole expanding to match Luka's in size. As his pussy finished forming a huge clit spawned at the bottom, splitting his slit open as his lips suddenly began winking and drooling with pints of feminine fluids, soaking his balls and leaving a puddle on the floor.
Both taurs felt themselves going into heat, feeling the deep, hot, clenching need to be filled to the brim, and then bloated even further with cum. Slick felt an intense need to take something in both his holes but right now, his need to pump some seed was greater.
As his male equipment expanded to match Slick's, Luka felt his balls churn as an extra set thudded into his sack and a second massive dick thundered out from between his hind legs, already drooling quarts of precum.
He could feel Slick pumping him with pre by the gallon, bloating his womb and his intestines with his musky lube. He turned his head around to kiss Slick as their cocktongues extended again, drooling into each other.
Suddenly their throats began to feel extremely sensitive, and each felt their esophagus turn into a third, fuckable passage, lubricated and craving cum. To Luka, his throat suddenly felt like a second pussy with a heat of it's own.
With this new, pleasurable addition, both their brains whited out as they orgasmed everywhere at once. Their cocktongues dumped cum by the gallon down each other's convulsing throats, milking each other's tongues for every drop. Luka's torso bloated with the deluge of spooge from Slick's massive balls, while his own equipment flooded the kitchen, sending spurts as far as 20 feet. His ass and pussy undulated and churned as they milked Slick's massive endowment for every drop of the dozens of gallons it was dumping into him. Meanwhile, Slick's new pussy went off in a sympathetic orgasm, squirting his juices for feet behind him as his pucker clenched and unclenched, desperate for something to fill it.
As they came, their balls were already churning and roiling as they cooked up fresh loads, extending their orgasm for minutes.
As they floated in a sea of pleasure, Luka felt his heats cool slightly, but he somehow knew that it would never disappear. His slit would always drool intensely with the need for something to fill it, and his throat would forever crave to drink gallons of cum. His balls would always need to be emptied, his dick would sling pre at all hours, and his thoughts would never be free of sex again.
Slick felt it too. His dick still ached to be in something again even as he pulled out of Luka. Even though he just came it was already pumping out precum by the gallon. But even more, his slit and ass needed to be filled NOW.
He walked around to the Luka's front and used a hind leg to pull his muzzle into his snatch. Luka shoved the tip of his muzzle into Slick's drooling and clenching slit and took a deep breath, the musky scent making his cocks harden so much they hurt as his balls swelled even larger between his hind legs, so large he could barely walk.
He needed to be inside Slick more than he needed to breathe, and Slick needed him inside just as badly. He motioned to Luka as his mouth was still blocked by his drooling cocktongue, and Luka understood immediately. He quickly speared into both of Slick's holes, immediately pumping in and out as fast as he could. He needed to cum and he knew Slick needed his cum too.
As Luka's hips slammed into him, Slick felt a new change start. Every time Luka's balls clapped his, he felt a jolt of pleasure as his chest began to expand. His nipples grew immensely, expanding across his chest and elongating as they were carried forward by a rapidly expanding pair of breasts. They pumped up with every thrust, already sloshing and aching as they filled with milk. They felt four more points of pleasure down their upper torso as 2 additional pairs of progressively smaller breasts grew beneath his first pair. They grew rapidly until the first was an F cup, with the second an E and the third a D. Despite reaching their final size, they continued to swell as they became so overfull with milk that they looked like they were defying gravity as they lifted off of their chest.
Luka saw this new growth and reached around to milk his mate, squeezing each nipple to help his friend relieve the agonizing pressure in each mammary.
As soon as he so much as grazed a nipple, though, it immediately sprayed out some milk before starting to pump milk by the gallon. Slick's breasts were so productive that even this constant stream was not enough to reduce the pressure in their giant milk tanks, they continued to fill with more and more milk even as dozens of gallons leaked out of their nipples.
As Luka massaged their nipples, Slick underwent their final change. The tips of their nipples gushed milk as something emerged from their tips. Each of their nipples was growing it's own cock! They expanded rapidly until they were as long as Slick's cocktongue, and their output increased as finally, Slick's breasts reached equilibrium. They pulsed and throbbed as they began to shoot out dozens of gallons per minute, Slick's dicks doubling their spurting output to match and their pussy started gushing so much fluid they almost fell over.
Luka reached around to jack off two of Slick's nipple cocks, as their tongues met again and they pumped their heads back and forth to fuck each other's throats.
Within seconds they reached their ultimate climax. Their cocktongues pumped so much cum down their throats that their upper torsos bloated so much they looked pregnant and their cum started to back up out of their mouths, dripping between them. Slick's nipples came and throbbed as they gushed with hundreds of gallons of milk while their cocks dumped their massive load onto the floor. Slicks holes convulsed around Luka's poles as their brain went white, eagerly accepting every drop he pumped out. Luka was so productive that with every clench gallons of cum and femspunk shot back out onto the floor.
Even so, he was pumping Slick so full their belly touched the floor and started trying to lift them up. Luka was lost in his own haze of pleasure as his dicks pumped endless amounts of cum from his debilitatingly large balls, pussy gushing with torrents of fluid as both it and his ass pumped out the excess of Slick's cum from their previous mating so he could be mounted again.
After 20 minutes, both were utterly exhausted, and finally separated. With mild concern, both could feel their balls ache painfully with a freshly churned load of cum, asses, pussies, throats, breasts, and tongues all demanding more action, but their bodies were too tired. They both fell asleep on the floor, drooling and dripping from everywhere.
An hour later, there was a knock at the door. Slick called for the visitor to come in, as they were still too bloated to move despite the gallons of cum dripping out of them every minute. As the door opened to reveal their neighbor, they could see her eyes instantly glaze over as their combined musk took over all of her thoughts, and she began to strip as she slowly approached the pair of taurs.
All the way down the hall, doors opened as the musk ensnared the entire floor, and dozens of fresh potential converts stripped as they approached the duo's apartment.
As their combined fluids seeped into the walls, soon the whole building would be full of hung, horny, dual-sexed taurs.
Slick and Luka couldn't be happier, after all, two taurs wouldn't be enough to satisfy each other.
