#8 of RiftVeil Labs- Transformation series

Iarann is an avid explorer who is looking to have a new change in his life and get further in touch with the nature he loves, seeking to have a body modification procedure of his anthro coyote self. After gaining a larger sized form and an additional pair of paws to help him out with the shift, he might have his "paws" full with the crazy incident that unexpectedly hits him next.

A commission write for Iarann. So to be fair, this is not my highest quality of work (mostly due to having writer's block and depression issues as of late x_x) but I'm pretty satisfied with how it turned out. Enjoy :D

Needs of a Taur (Coyote-taur TF)

Iarann adjusted his black leather jacket with a quick flex upon exiting the lift station of the facility, relief going over him for being out of that hot elevator shaft. Even though the ride was a mere five minutes to reach the lower level from the surface, he could feel the sweat soak along his grey t-shirt and along his dark brown furry neck. Of course, this type of environment was all too normal for the anthro coyote. He was explorer and tomb raider by trade, having delved into exotic areas across the globe for the last several years ranging from cave diving in the Brazilian rainforest to the ruins nestled in the sandy dunes of the Arabian desert. Yet despite all the fun Iarann had engaging with nature and unearthing new mysteries alongside others, the coyote still felt like he was missing something; that or maybe his urges for being quite a dreamer started to getting more to him. Whatever the case, it all lead to him arriving here at Riftveil for his appointment that he was already 10 minutes late for as he checked his watch and rushed past a human researcher checking their clipboard.

"Sorry!," Iarann quickly hollered to the man, shooting the coyote an annoyed look before reaching down for the clipboard. The office he was looking for showed the name plate on the side at the far left side of the main lobby sector of the west wing, the name "Gill" plastered on the side as he maneuvered past a few workbenches. He stopped for a moment at the door, leaning down to catch his breath from the rush; the excitement and anticipation were all he could feel now.

"Ah perfect timing, sir," remarked a voice coming from the office room, making Iarann's ears perk up before turning his head into the room to see who it was. Sitting behind the wooden desk with slit eyes still fixated on the computer monitor behind a pair of glasses, a green scaled lizard shot an eye and a warm smile back to the doorway as Iarann stepped inside.

"Were you expecting me, Mr.-?," the coyote inquired with a few steps toward a brown cushioned chair.

"Gill," replied the lizard with a look back at him, alternating between the guest and the bright monitor as he finished typing his report. "And yes, you could say I was expecting you Iarann; our security staff mentioned you arrived about 10 minutes ago. Luckily, you're the only procedure scheduled today so it's no biggy for running a tad late," chuckled the lizard as he removed his glasses, placing them down on the desk. Gill gestured out a clawed leather hand toward the cushioned chair in front of the desk. "Please, have a seat. I need to run a few things by you before I take you to the procedure bay."

"Oh, ummm...certainly," Iarann spoke before slipping into the chair, his hefty muscled weight sinking into the soft cushion and bumpy backrest. "And first off, I do apologize for running late," he said with a brush of his hand behind his furry neck. "It took longer to find the location from the drive with the directions you gave me. Heh, I didn't realize I literally drove by the place two times before it hit me that the small blue house was the entrance." The coyote gestured with his hands outward. "I was under the assumption it was a BIG structure that you couldn't miss," he chuckled.

The green lizard smirked with a nod in his chair, leaning back a bit. "Indeed. You aren't the first to mention that or get lost finding this place. It's why we keep the bulk of Riftveil underground, besides for....security reasons." His gaze narrowed somewhat. "In any case, what matters is at least you found the place and arrived for your appointment, despite a slight delay. So then..." the lizard spoke while taking up a hologram clipboard, dragging over the coyote's image on his schedule list to pull up his biometric data sheet, "let's review your procedure request. That way you have full knowledge of what to expect; and...so we aren't held legally accountable for any...accidents."

A slight gulp tickled in the coyote's throat. "Right...I understand."

"Now let's see," muttered the lizard with a glance over the file through his glasses, carefully reading over the data and request statement that Iarann provided a week ago as the coyote listened on with full attention and responding as best he could to the questions the scientist asked him. For the most part, his procedure was expected to be pretty simple, since he was already in his original body form. The main thing Iarann was interested in was becoming a full-sized taur version of himself, giving him an augmentation to his lower body so that he could not only be for physically fit but also become a dream version of himself he always wanted to be. However, there was also an extra stipulation attached that the coyote insisted having done, which would be rather...odd, to say the least.

"All we need now is a blood sample to tie into your data file for our records and we can start up the procedure," remarked the lizard after several minutes of explaining safety protocol to the giddy client. "Do you have any other questions on anything I didn't cover?," Gill asked with an intent stare at the coyote. Iarann pondered all the details with a stroke of his furred muzzle as the lizard set aside his glasses. Everything did check out from the information they gathered from him, even down to what exactly they were going to do to him. Of course, science wasn't much of his strong suit so it kind of flew over his head as he was more fixated on how awesome it would feel to be a taur after all was said and done.

"Just one," Iarann spoke with a last stroke of his chin. "So...is all this going to be 'temporary', or...permanent?" Normally patients tended to ask about how agonizing the change could be, only to be so easily proven wrong when they get flooded with all the pleasure feelings during the shift; yet when it came to pain, Iarann was no wuss. Being bitten by poisonous snakes and remembering the feeling of those toxins destroy cell after cell in his blood vessels and having to wait long hours for the burn and torment to die off was WAY worse than anything this place could probably throw at him. For him, it was more about taking a step to something that could change his life forever, and if he was ready to take it at that. "I just need to be sure is all...so I don't have any doubts or 'buyer's remorse'," he chuckled with a brush of his hand behind his head.

"Oh ho ho, most definitely," replied the lizard with a sensible chuckle of his own. "We try not to keep anything of that nature secret from clients. As to that point...the effects you will have as a 'taur' will be temporary, initially. The beauty of this transformation procedure is that we are simply adjusting the genetic structure of your body, or more so adding to its line of coding. For all our other procedures we've done, a complete makeover change involves re-writing their code almost completely, hence why those types of procedures are permanent," explained Gill as the coyote nodded from his chair, stepping up from a slight ache in his upper back shoulder to stretch the muscle out some. "So in short, the treatment will be temporary for you today. Though if you want the effects to be permanent, we can simply schedule a follow-up visit to give you a potion for that."

"Great!," smiled Iarann with a quick nod. "Feels good to hear that. I uh...tend to make hasty decisions sometimes without thinking too much on them. But knowing that now, you know with having a choice in the matter heh heh, it DEFINITELY makes me less nervous for sure."

"Splendid, sir," Gill said, striding around the wooden desk with clawed feet stepping about the carpet floor. The coyote's ears perked again from the sound of a few bell rings going off, glancing down to Gill's coat pocket as the lizard reached to retrieve his phone. "Oh. Heh, looks like my colleague is finished with the preparations in the second procedure bay room," he spoke before locking the phone screen and glancing back into Iarann's blue eyes. "If you'll follow me, I'll take you to the room now." The lizard strode past the coyote, his large green tail swishing about under his white coat before turning the corner of his doorway.

My god...this is really happening!, the coyote pondered to himself as he followed close behind, a silly grin coming over his muzzle as his brown tipped tail wagged about. Mmmmm I can only imagine how this is going to feel. Urrrgghh...the anticipation is killing me! His eyes darted to the side entrance of the second room just several yards from Gill's office, looking over the tinted blue window that lined the side. The lizard only needed a moment to swipe his keycard on the pad terminal to the side of the slider doors, the digits beeping in sequence before a green bar light swept over the pad as an approval. Gill turned slightly to glance back at the coyote, who could only look on with curiosity before seeing the slider doors open and the light coming on in the dark room.

"After you, good sir," Gill replied with a hand gesture, letting the coyote step inside as he followed suit, leaving the doors to slide shut just behind them.


"Uhhh...this isn't what I um...had in mind for a simple procedure," spoke a rather-awkward standing Iarann, staring down at the metal platform touching his cold paws on the floor. It was already somewhat of a nervous feeling completely undressing behind a blue curtain in the corner room moments ago; but now he felt more like a test subject than an actual client in his current situation. The moment the coyote stepped on the metal plate, two arms snaked out of the top wall with clamps and instantly held him in place while he stood up, fastening on his lower wrists with a snug sponging cushion in the inner lining to make it not completely discomforting.

Wasting little time, the lombax rolled the computer cart to the center of the room, stopping it just to the side of the client. Taking a small capsule gun from his coat pocket, Bolt rubbed a cold ointment cloth on the coyote's upper arm and then with a careful placement of the gun end, he pulled the trigger; in a split second, it felt like a pin prick to Iarann as a small sample of tissue and blood was captured from his arm. "There we are," remarked Bolt while typing away on the computer, the scanner instantly picking up his genetic makeup through a full body biometric scan.

"Is that really necessary?," Iarann stared with a hesitant look in his blue eyes, twitching his arm as the sensation started to fade. "I mean, I did mail you in a sample of my DNA like you asked."

"Yes, but you see that was to make sure we could prep the potions or any other compounds needed that we were going to use in advance," smirked Bolt as his eyes remain fixated on the bright blue screen. "This was just to check your current health status." The lombax hummed to himself with a stroke of his chin, scrolling down the chart as all the areas matched up well. "Hmmmm, no signs of any foreign activity in your body. And...your DNA matches the sample you sent us." Bolt gave a toothy smile. "So...we're ready to get started!"

"W-wait a minute," Iarann mentioned with a puzzled expression, watching over the giddy feline who quickly approached his right side with two small vials and the capsule gun. "What do you mean 'my DNA matches'? Why wouldn't it if it came from me?!?" Even while on the inside the coyote was still just as excited as ever at the whole taur prospect, he still couldn't help but be a tad nervous at the sight of the gun and the pink and purple vials being shook slowly in Bolt's right paw. After all, this was the first time he came face to face with this group. What's to say this could be all a hoax?

"Oh?," inquired the lombax with a twitch of his long blue-striped ears. "Heh heh, nearly forgot to mention that," he said with a chuckle. "It's the other hidden reason we run another scan: so we know it's the real client. Might sound silly...but we've had an imposter preach this place before. Since then, we've stepped up security a bit."

"Ah...fair enough, I guess..." shrugged the coyote through his arm restraints, shifting his chilled paw pads on the metal floor a bit as he felt another ointment cloth rub over his brown fur on his upper back shoulder. "Gonna stick me again, I see?"

"Nah," smirked Bolt from behind as he positioned the gun on the shoulder. "I'm giving you a suppressing agent."

Iarann's let out a slight growl as the plunger came down, feeling three tiny needles puncture his coat before shooting a small dose of liquid into his blood stream. The coyote rolled his arm some with an initial discomfort, but immediately began to feel a slight chill on his inner body sweep over him as the pain vanished in an instant, making his teeth chatter some. "Brrr...I-I f-feel so c-c-cold..." chattered the coyote as Bolt uncorked the pink vial.

"Yea, sorry about that sir." The feline quickly raised the vial to the canine's lips, nodding for him to drink. "Take this; it'll get rid of the chill." Iarann nodded, taking the glass tube in his maw and gulping down the small amount of pink liquid. Bolt removed the vial and placed it in his coat, watching the coyote give a few licks over his snout.

"Mmmph...odd...I don't feel anything. No cold...no pain. Heck, I didn't even taste anything on...whatever that stuff was," he said while sticking out his tongue, leaving the lombax chuckling some.

"Yeah, that's science for ya," Bolt smirked. "Your body can still feel any sensations actually. Though not as strongly for the moment. That 'tasteless' potion mainly dampens your nerve cells so they can't fire off signals as easily. Hence you'll get like a few second delay before you feel a large stimulous, such as say....me kicking your ballsack," he grinned with a quick stare at the swaying pouch just below the canine's sheath. Iarann grimaced quickly at the thought, but Bolt simply waved him off with a paw. "Relax, I'm not that cruel." He grinned. "At least not to you anyway," he winked.

"Heh...you sure are a strange scientist," nodded Iarann with a slight sweat running along the side of his face, watching the purple vial with odd red dots moving around in the solution. "And ummm...thank you for uh, not doing that. Those are....p-pretty sensitive."

_They'll be ten times as sensitive in the next several minutes, friend,_thought the lombax to himself at the statement. "Not a problem," nodded Bolt. "Now then." With a few shakes of the purple vial, watching the red orbs pop and suddenly vanish into the mix, Bolt uncorked the vial and raised it up again to the canine's snout. "This stuff is going to taste VERY nasty, but I need you to drink all of it."

Iarann gave a loud gulp, his ears folding down some as his eyes switched between the purple substance and the lombax. "Bad? As in...?"

"Almost like drinking an overly ripe smoothie."

"Wait...how do YOU know what it tastes like? Unless you..."

Bolt gave several quick nods, a more stern stare showing on his brow. "Yes yes, I know because I drank that shit before. Ummm...pardon my manners," he said with a quick look to the side before continuing. "Long story short: the doctor had me drink it, I grew bigger and had an extra set of legs, and a few other side effects. So yes, I became a taur, just as you'll be when you drink this, alright? Anything else?" Bolt seemed to be getting somewhat edgy for once; then again, he was on a set schedule. He didn't want to miss game night later this evening with friends.

"S-so if I drink all of this....but," Iarann shook his head with a puzzled look. "W-what if I don't dri-".

Errrgh...this is getting nowhere, grumbled Bolt in his head. The coyote was cut-off instantly as he felt the glass vial push into his mouth, his eyes opening wide in surprise as he naturally gulped down the thick beverage being emptied into his muzzle. His body shuddered a bit, his tongue shivering in his muzzle with the taste of the brew hitting the appendage. The lombax was right: this stuff was vile! And unlike the other vial, this one was completely full, holding almost half a cup of the drink. With each swallow Iarann bit back the urge to hurl, his body trembling all over in the restraints, telling him to get this garbage out of him. That is....until the moment it hit his gut and his legs began to twitch.

A low growl and moan spilled out of the coyote's maw, an odd tingle sensation vibrating along his thighs and sheath as his hot red canine rod began to peek out of his hiding hole, feeling as if something had disturbed its slumber.

"Ugghhh...man that's....oooohhh..." Iarann moaned with his head tilted back, his body becoming conflicted with getting out that foul taste in his mouth while aroused at growing sensations sweeping over his muscles and lower extremities. Bolt simply chuckled from the side as he monitored the client, seeing his heart rate elevate while his tongue began to dangle out. To the coyote, he was experiencing a full blown body massage, kneading out those growing muscles with each passing second.

But for his sheath, oh: now THAT was ten times more gratifying! Slowly that red hot rod inflated in size, the veins on it throbbing with increased blood flow while a steady stream of pre began to bubble out from the tip. Below those hefty orbs were expanding as well, no doubt from those phantom-like rubs of soft-plush paw pads massaging over them. The lombax could only smirk at the sight; after all, he had the treatment before so he knew full-well how exhilarating the experience was.

With only a few minutes passing, the coyote spine had already stretched inch by inch as he grew taller in the restraints, giving partial winces with each additional spine bone that popped into place. To be fair, it was the only real painful part of the procedure since these sensations were directly linked along his spinal column, having to endure all those nerve centers being ripped apart and then reformed. Still, taurs were big: Iarann would need all the size he could get with those extra set of large paws coming out.

"Woww....heh...this is....I don't...even know how...to describe it!," panted the coyote, getting a brief shot of Bolt laughing behind him as the lombax came up and gave the taller coyote a quick belly rub, hearing him murrle from the attention over him.

"Oh yeah," snicker Bolt, seeing the client buck a bit from the arousing rubs. "Nothing like getting a hot massage session on your paws, crotch, rump, and anywhere else you can think of while you get bigger, eh?" Ah...looks like those feet are growing in now, pondered the lombax with another rub along his mid-waist. Iarann was too much in bliss to notice his belly getting slightly heavier, even contracting more through his bucking and squirming in the restraints. On the outside, it appeared as if he'd been knocked up recently from the growing mass; yet as it began to push out forward like something out of an Alien movie, those tiny digits wiggling out of that light brown coat well all the indication that the treatment was reaching the climax point.

"Eeggghhh!!!" Iarann shuddered at the new sensation on his chest, feeling a large mass of limbs begin to spill out rapidly to the metal floor while his backside stretched farther out behind till it was no longer on the plate. His tail wagged fast behind him, eager at how good and rich it was to be a larger fur while moaning some from his hot tip dragging along the cold metal below, drizzling his juices over the side. The explorer would probably be rather embarrassed if he saw just how horny he was getting with each passing moment.

Fur instantly sprouted over in dark and light shades of brown over his new limbs, flexing about as the paw pads rubbed against the cold metal floor below. Despite having an extra set of legs to control now, the coyote-taur seemed to be already well acquainted with using them as he moved about in place. That's when a large moan and growl erupted from his lips, having Bolt's ears perk up as he quickly saw a spike in Iarann's heart rate. Initially he showed concern for client, since he didn't want the final parts of the change causing his body to go into systematic failure from too much impulses affecting his nervous system. Just when he was about to speak though, he stepped towards the taur's front to only get a shot of white fluids splatter below his chest.

"Oh....well that explains it...," Bolt facepalmed himself before wiping away the fluids from his fur. From the looks of those new paws stroking over his growing shaft, it made sense why his heart rate elevated; after all, giving one's self a vigorous paw job with larger paws will tend to do that to you. Yet at the sight of it...a wicked smile started to come across the scientist. I mean, they were alone in the procedure room; it's not like anyone would know what happened if the feline decided to...collect a few taur samples for later use. "Hmmmm....Vash probably won't care...but how to do it," he mumbled with a stroke of his chin, staring at the back of the room at the equipment left about. For Iarann, who seemed to be muttering random noises at this point, it was all about flexing about those cushioning digits of his new feet up and down that hot red and slick rod of his with his head still tilted back. Even a few gentle squeezes of that cock flesh were enough to make him yip and bark in ecstasy, dousing his long brown coat in his fluids from large spurts. The changes might have been finished for the procedure, but this coyote was far from having his fill of the moment.

Meanwhile, Bolt was already snickering to himself from wandering over to the back left side of the room, grabbing a vacuum pump with a large cylinder container on the end. Normally the device was used for transfusions or cleaning up large messes if warranted, which in this case....seemed to be valid. Just need to adjust the nozzle some and....perfect!, the feline smirked as a larger glass tube end was expanded on the end. With a cock that big now and one that could certainly get larger from what he planned to do, making the drainage end wider was a necessity now. Besides, it's not like Iarann was in an objecting mood as he bucked more and more in the restraints, even while Bolt fastened the end snuggling over his bulbous cock just above that knot of his.

"Erghh...been a while since I used this damn thing," Bolt focused for a moment while punching in the new settings on the vacuum device. If Vash or anyone else found out about this little escapade, he wouldn't hear the end of it; the "feline with an urge of milking clients for samples" wasn't something he wanted to be known for. "Alright, let's start er up!" A flick on the switch on the end was all that was needed before a large suction on the hose instantly began to pump along that fat canine cock, making Iarann moan heavily at the new sensation. His body could somewhat sense what was happening, despite his mind running on his animal instincts atm. Already the machine began to drain large doses of white coyote seed down the tube with each pump, stimulating those orbs below into overdrive to keep up with the milking process. The taur panted and squirmed in the bindings, only being able to pleasure himself with those new limbs; still, that seemed to be enough from those new paw pads massaging those orbs for more and more of his seed as his cock inflated rapidly to into the glass tube.

It seemed like a mad science experiment to literally be milking a client of their own cum while they were just getting used to the aftermath of their transformation, yet from Bolt laughing and Iarann growling/yipping back and forth, there was little doubt that any of them would object to the idea.

Iarann's libido was on fire with each buck he made in place, orgasming left and right into that glass tube as it drank off that thick seed. And after going a solid fifteen minutes of shooting off large shots from his crotch, it was any wonder how long he could keep this up; he now had orbs the size of grapefruits dangling below that were churning full of seed just waiting to be squeezed and milked for all their worth.

Suddenly, a somewhat worried look started to come across Bolt as the taur howled loudly with another massive surge, making the feline stare back at the door. Crap! He's not gonna pipe down! The feline quickly leapt onto the large coyote's back, grabbing his head and giving it several shakes while it still leaned back. "Hey, stop it damnit! If you keep barking, someone's gonna come check in here!" It was no use though. Staring into those dilated blue eyes, Bolt bit his lip before hoping down and rushing over to the drawers along the back wall, rummaging for a tranquilizer as his ears picked up chatter coming from outside. Someone was coming, and he had to act fast! Great...never expected having to knock him out cold...but shit, I need to calm him somehow. Taking the large dart, the lombax rushed back over before plunging the needle straight into one of those thick thigh muscles, holding it in place as the drug entered Iarann's body.

"Ooohhh....uggghh....whhhattt...mmmm," mumbled the coyote as his head flung forward, feeling the slight prick to his front as his eyes immediately became droopy. The narcotic was strong, knocking him out faster than boxer could ever hope to with a well-placed punch to the head. His ears sagged while his head swayed from side to side before dangling lifelessly before his large frame, leaving his cock to sputter out the remains of his horny seed into the suction device. Bolt quickly turned the device off, crouching down to carefully remove the glass tube off that fat cock. It had swollen so much from stimulation that it looked like the glass was already fracturing in spots, being barely able to contain that monster.

"Bolt, is everything alright in there?" It was Gill from the sound of it, making the feline grimace even more as he dragged the device to the back wall while Iarann drooled somewhat from his maw in his slumber.

Great...why did it have to be the lizard of all thing?!? He can TELL when I'm hiding something, and it'll take a bit for my coyote friend here to fully recover from the ordeal. Bolt brainstormed fast as he adjusted his bracelet on his wrist, setting the scanner on the metal plate panel of the room to monitor Iarann for the next 12 hours. At least until he returned, he'd be keeping an eye on him somewhat. Alright, that should take care of him for now. I can sneak back over here in the morning and cart him back to the entrance...somehow.

The feline sighed, adjusting his coat with a glance back at the sleeping taur before staring down the door, seeing a silhouette of Gill already approaching. O boy...now for the fun part: keeping Gill and everyone else out of the room for the next 12 hours. The feline stared down at his bracelet, his eyes lighting up at the icon labeled "decryption/hacker". Hmmmm....maybe there might be an alternative after all, heh heh.

With a few strides forward, Bolt's tail swayed about beneath his lab coat as the room doors slide open, stepping out into the main lobby to "greet" his lizard colleague as they shut quickly behind him, leaving the large brown coyote taur to snore in his restraints while his front paws gently massaged over that fat shaft of his. Based on that silly grin in his muzzle, it can be safe to assume he was really enjoying whatever he, or whatever taurs, like to dream about.
