Stepping through the two sets of double doors, Gabe was surprised at just how sharp the transition was between the freezing cold weather outside where the blizzard was still raging strong, and the front lobby of the pharmaceutical company's offices that were so snugly warm he immediately began opening up his heavy winter jacket. The Maine coon cat wasn't the only hopeful visitor, from the look of it, with many of the seats in the lobby filled by people waiting patiently, one of them in the middle of getting up to head to one of the receptionists.

After stomping the snow off his boots, Gabe headed for the desk with the 'Inquiries' sign hanging over it, giving a small wave to the immaculately dressed vixen behind the desk. "May I help you?" she asked him as he approached, looking up from the computer in front of her.

"Yeah, I'm here to take part in a trial," Gabe explained, pulling off a glove and reaching into an inner pocket on his jacket.

"Ah, another one for trial 44078?" she remarked, holding her hand out expectantly as Gabe took out a piece of paper. But after glancing at it, she raised an eyebrow, glancing back up at Gabe, then at the paper, then at Gabe again. "Ah... YOU'RE here for 5377," she remarked, as though the numbers meant anything to him.

"I... guess I am?" Gabe offered, shrugging as he took off his fogged-up glasses and wiped them clear on his shirt before placing them back in front of his brown eyes.

She gave a little smirk that he wasn't quite sure what to make of, and typed something into the computer. After hitting the Enter key, she turned the screen to face him and lifted up the keyboard, placing it on the edge of the counter. "Enter your details, please," she instructed, and he set his gloves down so he could type. There was some extremely long legal disclaimer at the bottom, but he didn't have all day, so he skimmed over it; references to various laws, blah blah blah, patient details are confidential, etc etc, no liability for damage or destruction of clothing, weird but okay, patients must follow instructions, yadda yadda...

Once he had filled in the form and signed it, the receptionist took the keyboard back and typed something in before hitting the Enter key with flourish. Looking back at him, she began, "Doctor Fang will be right along, so if you'll please take a-"

Before she could finish her sentence, the double-doors at one side of the room were flung open by a tall wolfess with dark gray fur and amber eyes, her fluffy tail and waist-length hair both a lighter shade of gray, wearing a long labcoat that went all the way down past her knees. "Gabe?" she called out expectantly, yet cheerfully, and Gabe could swear her tail was wagging.

"That's... me," Gabe answered, raising a hand. He glanced back at the receptionist, but she only smiled at him, though he was sure he saw her wink, too. What had he gotten himself into?

"Follow me!" Dr. Fang called out, waving Gabe forward, and he did as asked, stepping past the rows of seats where other people were waiting. He was starting to have doubts, and not just because of the way Dr. Fang's hips swayed back and forth almost hypnotically as he followed her along, barely paying any attention to the impeccably clean and sterile corridors he was walking through.

She suddenly stopped outside of a door, and swiped a badge she took from her pocket through a reader before entering the room. Gabe's unease grew, only to ebb a little when he looked inside and saw what looked like a perfectly ordinary examination room. It had one of those tables for lying on, some cabinets, posters, a sink, a box of gloves, and all the other things you'd expect to see in a doctor's office, plus a big mirror along the wall opposite from the table.

"Take a seat," the doctor instructed him, "And feel free to hang up your jacket."

"Oh, thank you," he replied gratefully, hanging it on a hook by the door. Under it he was dressed far more lightly in a long-sleeved shirt and some tan slacks, his collar of fluffy fur sticking out over the top of the shirt. Taking a seat on the table, he tried to lighten the mood by asking, "So, uh, should I roll up my sleeve, or...?"

Dr. Fang turned and gave him a smile, opening a cabinet and taking out a white plastic bottle with no label, instead just bearing "#5377" on the side, written in sharpie. She gave it a shake, its contents rattling around for emphasis. "No shots, just pills," she reassured him.

"Ah, good. Um, by the way, when do I get paid...?"

"You'll be given the full sum on completion of the trial." Nodding, he held out a hand, but she didn't hand the bottle over to him right away. "I would also recommend that you start wearing much baggier or stretchier pants than that from now on." She gestured to his slacks, and he glanced down, then looked back up at her questioningly. "In case of side-effects," she explained.

Gabe hesitated, but $2000 was still $2000. He could afford to buy a few extra pairs of pants. "Anything else?" he asked, his eyes on the bottle as she handed it over to him.

"Take two pills with water before you go to bed each night," she instructed. "Now, I just need to take a few measurements and you can be on your way..."

--------------------

After a lot of seemingly routine measurements like temperature, blood pressure and so on, Gabe had left with the bottle of pills stashed in his jacket alongside the doctor's business card. It certainly seemed easy enough: just take the pills for a week and he'd be two grand richer. There had to be some kind of catch, but these things were tightly regulated, right? So it had to be safe. He made only one small detour to buy a couple extra pairs of sweatpants and track pants, then headed back home.

The pills were unremarkable when he shook a pair of them onto his hand that night, each just dark green and yellow. The only notable thing about them was their awful taste, but he didn't feel any different even after several minutes, so he went off to bed and curled up under the covers.

The next morning when his alarm went off, Gabe yawned and stretched as he reached over and switched off the alarm clock. It was back to work for him. The dress code permitted sweatpants, right? Most of his coworkers certainly seemed to-

Gabe's eyes widened as he swept back the covers and noticed the bulge in his pajamas. Morning wood was normal – but it didn't normally go past his knees and his balls certainly weren't THAT heavy.

It had to be the pills. Tugging off his pajama bottoms, Gabe stared in awe at his stiff cock as it bobbed upwards, free of the fabric confining it. It was definitely bigger, and thicker too, but his balls had grown substantially, each one now the size of a tennis- no, a baseball. His girlfriend Jade would certainly be pleased, but Gabe felt apprehensive.

Without bothering to get dressed, Gabe went bottomless over to his closet and dug around in the pocket of the winter jacket for the doctor's business card, immediately calling her. As it rang, it occurred to him that it might be an office number, but she picked up on the third ring. "Hello, Dr. Fang speaking," she answered.

"Doctor! It's me, uh, Gabe, from yesterday, the trial, uh, 5377," he fumbled in a panic, before taking a deep breath. "Something's wrong!"

"What's wrong?" she asked, sounding concerned.

"My, uh, well, uhm, you know," he stammered, then breathed again. "Did you maybe mix these up with some, uh, 'male enhancement' pills?"

He heard her hum for a moment. "I see. And how much bigger have your penis and testicles gotten?" she asked nonchalantly, sounding more interested than worried.

"Uh, like, a few inches?" Gabe guessed, murmuring, "I was already kinda big... um... but my balls are way bigger now! They're, like, baseball sized! I can barely hold one in each hand!"

He heard her writing something down. "Fascinating. Beyond projections, though perhaps I should have measured your initial size... anyway, let me assure you that this is nothing to worry about, Gabe," she said reassuringly. "Keep taking the pills."

"But-"

"If you don't complete the trial, you won't get paid..."

He bit his lip. Two thousand dollars! And what was he so worried about? Guys all over the country wasted money on pills for bigger dicks that didn't even work. Here he had some that really worked, AND he was being paid to take them! "Okay," he replied after a moment. "Thanks, Doctor."

"Of course. Have a good day, Gabe," she replied, and hung up.

Gabe put his phone down, and looked at his thick, throbbing cock, then at the clock on his phone screen. He had time to take care of this problem, and hopefully it wouldn't cause any issues at work. He put down his phone and idly stroked his cock as he walked to the bathroom, finding that he was a little more sensitive than usual. Opening the shower door, he faced it as he stood and jerked faster, not wanting to take too long and make himself late for work. His other hand held one of his big balls and caressed it as he jerked off, thinking about Jade. She'd definitely love his new size. Maybe he could surprise her with it the next time they-

Grunting, Gabe spread his legs a little and shuddered as he brought his quick self-care session to an end, though the climax itself was anything but quick. He groaned as thick ropes of his cum splattered over the back wall of the shower and ran down the tiles, loudly and messily erupting from his tip as he felt his balls pull upwards in their sack on each shot. He came harder than he ever had before, and when he finally opened his eyes, he was astonished at how much of a mess he had made of the shower, cum dripping down the tiles thickly.

--------------------

Gabe stumbled through the automatic doors, trying to ignore all the stares that came his way. He couldn't really blame them: it looked like he was smuggling something in his pants. It didn't help that all the plain-colored ones he had were dirty, so he was forced to wear a pair of tartan sweatpants, and all of the lines only further accentuated the massive bulge made by his endowments. Each of his nuts was the size of a basketball – yesterday. Today they were even bigger! Each one was wide enough to cover his leg and still stick out some to the sides, and his cock had grown to match, making an immense bulge of its own running down the front of his pants over the two orbs and down under them.

The receptionist stared in awe as he approached, her eyes not moving from his loins as Gabe stood in front of her. "Can I help you?" she asked him again, though in a far more sultry tone than last week.

"I'm- I'm here to see Dr. Fang," Gabe stammered. "Uh, clinical trial, um, #5537... er, no, #5377..."

The double doors at the back flung open again. "Gabe!" Dr. Fang called out excitedly, "Just the man I wanted to see! Come along!"

"Call me, stud," the receptionist whispered, passing Gabe a business card that he took without thinking.

Gabe had to be careful not to knock over any of the little stands or displays as he went – or other visitors, for that matter. "Sorry. 'scuse me. Sorry. Coming through..." he murmured, his immense package bouncing and wobbling around with each step. He'd figured out quickly how to move effectively with all the weight up front, but it didn't make it any easier to avoid smacking into things.

Dr. Fang led him back to the same examination room as before, and he hung his winter coat up again before heading to the table. "Pants off," Dr. Fang instructed, and Gabe shyly pushed down his sweatpants, letting his cock and balls hang freely as he took his seat on the table – not a single pair of his underpants could possibly fit him anymore, so he was going commando.

"Oh!" she exclaimed simply as she saw what he was packing, staring wide-eyed for a moment before straightening up. "Even more effective than we had hoped!"

"I thought you said these were side-effects..." Gabe murmured.

Dr. Fang shook her head as she opened a drawer and pulled out a measuring tape. "Oh, no," she began as she started taking measurements, "The growth is expected. The potential side effects could have included sudden erections. Quite hazardous to you and to people around you if you don't have stretchy pants."

"I... see," Gabe murmured, watching her measure him up, writing down each one: cock circumference and length, then the same for his balls, as well as his whole sack's width and height.

Her hands rubbing against him made his shaft throb and swell, to which she simply replied, "Ah, yes! Good idea, I should get an erect length as well," and rubbed one hand along his dick until it was at full mast, then stretched the tape out along it. "Three feet and... three-sixteenths of an inch extra," she mused, turning and writing it down. Her wagging tail brushed against his cock and made him groan, squirming in his seat.

"Uh... doctor..."

"Hm?" Putting down her pen, Dr. Fang turned back to him. "Ah. Yes, don't worry, I'll have someone help with that. I have... other business to attend to." He couldn't decide if the look she gave him was more of a smile or a smirk. "Thank you for your participation, Gabe. You can collect your check on the way out. Wait right here."

Not that he was going to wander around with a raging erection that would barely fit through the doors anyway. Gabe watched her slip out of the room, and thankfully, it was only a couple of awkward minutes of him glancing around at the posters, and occasionally poking his cock and wondering if it was going to go down on its own or not, before the door opened again.

"Gabe?" a feminine voice asked, and he saw a red fox peeking into the room, holding the door open a crack.

Gabe reflexively tugged his shirt downwards, an utterly inadequate motion when his cock was jutting three feet out in front of him. "Oh, h-hi! Yeah, that's me," he answered.

She stepped into the room, wearing a plain blue shirt and pants typical of a nurse, though the shirt was struggling to contain the sizable bosom underneath. She had short, combed-back brown hair with a little purple streak on her right side, and her tail swished behind her a bit as she closed the door behind her. "I'm Nurse Mindy, Dr. Fang asked me to... take care of you," she told him with a smile.

"Oh," he replied, nodding, then watched as she undid the buttons on her shirt. "Ohhhh..."

She had another light shirt on under her scrubs, but no bra, something immediately apparent as her big breasts bounced freely once she had opened up the second shirt. "Sit back and relax," Mindy urged, stepping closer to him and wrapping her tits around the end of his shaft, squeezing them against his sensitive flesh with both hands.

"Uhn... yes ma'am..." Gabe murmured, panting as she began pumping her breasts up and down the end of his cock. His hands held onto the edge of the table he was sitting on, gripping it firmly when he felt Mindy press her muzzle to the end of his shaft and slurp along it with her tongue, lapping up some of the precum leaking from his tip – the flow copious enough that it continued to dribble down the underside of his shaft anyway, onto her tits, slicking them up.

Expertly, she continued to raise and lower her body, sliding her breasts along the end of his enormous cock, though she could only tend to the top half of it. Gabe panted and leaned back as her breasts, steadily more and more covered with his precum, were squeezed up and down his shaft, all while she kept nuzzling, licking and kissing at his cockhead, lapping up some of his precum while most if it kept spilling over her front, making a mess of her as well as him.

Despite her instructions, Gabe couldn't help but rock his hips a bit, thrusting between her bountiful soft breasts, the tip of his dick pressing against her muzzle and making her lean her head back a bit. She took it in stride, giving him even longer and bigger licks in response, pumping and squeezing faster with her tits, making him moan out louder.

"Uhn... here it comes..." he groaned, his toes curling as he felt a tingling running along his spine indicating an impending orgasm. "L-Look out, I'm gonna-!"

She licked right over his urethra at that moment and he gasped out, shuddering on the table as his orgasm hit. A massive blast of seed erupted from his cocktip like a firehose, cum spraying all over her head and gushing off to the sides and down her front while some of it shot right past her head and splattered onto the ceiling. Gabe yelled out as he kept cumming hard, those enormous balls hanging in their sack churning and clenching as they unloaded with huge ropes of thick, hot cum that splattered all over the place.

The nurse continued to bounce and squeeze with her breasts even as they and her hands were quickly coated in a thick layer of Gabe's cum, more of his seed spraying all around and painting her white. The ceiling, the far wall, and the mirror got heavy coatings of his jizz, the excess spilling down towards the floor as he moaned out from his long orgasm, squirming and shuddering on the table, every upward clench of his balls accompanied by his urethra bulging out from the heavy load of cum surging through it and erupting from the tip to splatter all over everything in front of him.

By the end of it, Gabe was incredibly dazed as he stared up, cross-eyed, in the wake of his climax. His balls gave one final pump, and a splatter of seed that still would have filled a pint glass splurted out and ran down Mindy's already cum-coated chest. She was totally covered from head to toe in his jizz, and it was dripping from the ceiling onto her, the floor so completely coated that it was running out under the door.

Opening her eyes, Mindy stepped back just a little with a wet slurp, strands of cum still connecting his cock to her breasts. "Feeling better?" she asked playfully, shaking her head a little and sending drops of cum flying.

--------------------

As Gabe's cum splattered all over the 'mirror', Dr. Fang groaned on the other side, her labcoat open as she stroked her cock furiously, the herm's hand a blur. The unlit room on the other side of the one-way glass grew darker as more of Gabe's thick jizz splattered onto the glass, but she didn't care, lost in the moment as she trembled and shot her own load of cum, keeping her muzzle shut tightly to avoid making too much noise. It was nothing compared to even one blast of Gabe's cum, but she still shot ropes of her cream onto the mirror, her hand, and across her own front, her breasts getting a splattering of her own seed.

"Well..." she panted to herself as she came down from her peak, leaning on the back wall during her afterglow, "That was... quite something. Clearly the... experiment is a success."

She panted for a little longer, then turned to the intercom by the door and pushed a button. "Clean-up crew to exam room Alpha-Three," she instructed.

"And bring the BIG hoses."
