"Got a syringe?"
Ponyville Hospital Urologist’s waiting room had found itself inhabited with only two foals, a filly and a colt of about the same age; the colt, blue with an aqua green mane and the filly, white with a cream mane. They waited for their names to be called out in order to start their appointments.
The wait was supposed to be quite short, especially since the test was routine but it dragged on and on for reasons that the two were unaware of.
“Oh c’mon! Just what are they doing for it to take this long?” The filly complained after dramatically waving her hooves and exclaiming loudly. Looking towards the colt she noticed that there was no real response from him.
Sighing, the colt just stared at the pure white walls of the room, his gaze dull and unamused.
“What’s your name?” She asked. “Mine is Sweet Release.”
The colt took another deep breath and sighed. Thinking to himself that he just had to be stuck with a talkative little filly while he waited. “Azure Blossom.” He finally replied before going back to his original pensive position. He didn’t know why, but he dreaded this wait and she didn’t help any.
“Oh, I see, you aren’t very chatty. You look… scared.” She said, frowning a little, as she tried to empathize with Azure. “As if something big is gonna happen to you soon.”
The two foals then waited for a little while more. It didn’t seem like anypony would call them soon. Eventually the colt got bored of staring at the wall and looked over at the filly and spoke. “Do you know anything that can pass the time?” he asked.
The filly scratched her chin a little bit. She was a frequent visitor of the hospital, thanks to her father’s job, so she was aware of many things; up and including where to go if one was bored in the waiting room. Although, she didn’t want to go too far away. She thought for a little bit, until her face lit up with inspiration.
“There’s a private wing not too far away from here, we could visit that.” She said.
“Well,” the colt said, looking at the door that led to the appointment, “They haven’t called us in yet. We could take a look.”
Sweet Relief jumped off her seat, stretched her front hooves and walked away from the waiting room. Strolling down the empty corridor, on her right Azure followed close behind.
After a bit of walking through the alleys of the hospital, the two arrived in front of a dark green door with several planks nailed to it. Sweetie Relief casually bucked the door, making it open up with the sound of splintering wood.
“Easy peasy.” She grinned, strutting inside.
The colt looked inside. It certainly looked like part of the hospital, but the fact that it wasn’t lit was enough to reveal it didn’t see much use. Most of the doors were unhinged and the floor was dusty, in stark contrast with how the rest of the hospital looked. The lights, when turned on, flickered slightly before agreeing to the task of revealing their surroundings.
“Creepy,” the blue colt whispered to Sweet, a little unnerved by the turn of events.
Sweet Release shrugged with a chuckle. “Oh, it’s not so creepy. Just a bit underused. I mean, the nursery looks like it has just been abandoned, and most rooms are still quite clean.”
He nodded, not really agreeing with her. However, one word caught his attention and he frowned. “Nursery? Like for foals?”
“Yeah. What else?” she said “Wanna see it?”
His interest piqued as to why a nursery would be abandoned, he nodded in affirmation. After all, they had all the time in the world to explore, in his mind.
Sweet Release giggled, as she read the colt’s expression of interest. She gestured to the door on her right. “This way Azure.” She said, as she opened the door to the nursery. The nursery contained five white cribs, what looked like a metal changing table and several pieces of machinery of unclear function.
“Doesn’t look too much like a nursery to me,” he said, gazing around the room. “There’s a lot of machines around here…”
“Well, what did you expect? This is a hospital’s nursery, clearly they gotta do a lot of things that they can’t do with either magic or hoof,” Sweet Release said. “Besides, more things to explore!”
“I guess,” Mumbled the colt, still unnerved by the machines. Doing his best in not to think about how they could be used for the moment. “I wonder if they were foals like us or younger…”
“Weelll…” She said, looking at the ceiling and smirking “We could test that out.”
Azure made a face at her. “What? Really?” he asked, looking around. “What if it’s… cursed or something? After all, it’s still magical and stuff…”
“Cursed? I don’t see why it would be.” Sweet Relief stated as she walked towards one of the cribs, smirking all the way. “And besides, what kind of curse could have been put on this place?”
“Good point,” the colt murmured, but still had a few doubts about that given the spooky nature of the area and the fact it was abandoned in the first place. “Hey, wait for me!” he called, not wanting to be left alone.
Sweetie Relief chuckled, as she had another idea pop in her mind. “I’m thinking, maybe you’d like to play around with these? Diapers mustn’t be too far away, so if we start to play babies or something…” she stopped herself mid-rant to mentally berate herself. “Nevermind. Though, I’d try some of these stuff out.”
“You try it out first,” Azure Blossom said, looking grossed out at the idea. What pony in their right mind would regress themselves to a foal?
Sweet Relief quickly ran towards the changing table and looked underneath it. She spotted several unused packs of diapers still lying there, ready to be used. Sweet Relief grabbed one of them, labeled as ‘Silly Filly Diapers for Big Foals’, and opened one up, revealing a variety of diapers inside. She pulled one of them out of the pack and unfolded it onto the floor, then placed herself onto it.
Azure looked over, surprised that she was serious. Trotting over to the filly and her diapers, as much as he didn’t like the idea but it was something to do. “Need any help?” he asked her curiously.
The filly quickly taped up the diaper onto her crotch. She got up and shook it, making it crinkle very loudly and taking a few waddling steps forward, shaking her head.
The colt looked a little unhappy that he was ignored like that. “Okay then,” he said, looking the filly over. “How does it feel?” He shook some of his mane away from his eyes, his head tilted in a questioning pose.
“Feels good,” she said. “Wanna try one on?”
“I'll… I'll pass,” he muttered, blushing. She looked cute to him, younger than her age. “Unlike you, I'd like to keep my potty training.”
“Oh, c’mon,” she said, walking towards him and brushing her tail under his muzzle. “I know you’ll like it. I can just read that on your face, you just gotta have the guts to do it!” Sweet Relief said, as she turned around and walked towards the diaper pack and took another one out before picking it up with her mouth and trotting back towards Azure Blossom. “Ready to diaper up?”
“I- but- erf…” He grew flustered, a beet red. “Fine, but this is your idea!” Azure pouted a little, looking away while he laid down on the floor.
Sweet Release giggled, unfolding the diaper and sliding it underneath Azure’s butt before pushing it down over his crotch and taping it up. “There, all snug and warm!”
The blue pony, noticing she completed the change, stood up with wobbly legs. Unlike the filly, he looked uncomfortable in the soft padding that made him walk funny.
The sight of the colt’s discomfort made Sweet Relief giggle, as she went on to poke his padding, making it loudly crinkle. “You’ll get used to it, trust me!”
He muttered something under his breath. “Trust you… right…” Just wearing the diaper made him feel like a foal in need of a change.
Sweet Relief then quickly walked towards one of the machine, one made of a metal oval sphere and a small bedding in the middle. She quickly climbed ontop of it and laid down on the mattress, looking at Azure and winking at him.
“Hey!” he said, running after her unsteadily, nearly tripping over his own hooves as he hurried to her. “That might be dangerous!”
She giggled as she rolled onto the mattress. “And what coudl be the worst that could happen? A scrape on my knee?” she said somewhat jokingly. “Not that a sissy, trippy colt like you could tell me what’s dangerous and what is not!”
“Sissy?” He frowned, taking offense to that statement. “I’ll show you what being a colt means!” Without much thought, he waddled to a similarly-shaped machine and landed softly on the mattress inside.
The filly giggled. “Well, somebody has to activate it first,” she sing-sang “You just happen to have taken your seat later, so…”
He rolled his eyes. He wasn’t about to be outdone by a filly, so he hopped off the bedding to flip the nearest switches, not caring what they did before hopping into the pod, sticking his tongue out at her.
The ovals quickly closed onto the foals. Sweet Relief and Azure Blossom, now inside the pods, noticed several metal rods poking them all over before sliding into their diapers through the leak guards, making her blush and him squirm. Sweet’s blush grew stronger as she felt one of those bars brushing against her young private parts, stopping just underneath them. there was a whirring sound, where tension grew high and... nothing seemed to happen.
“Is it… broken?” the blue colt asked uneasily, more than a little tense. “Are we stuck in here?” He dared not move as the cold, metal bar whirred downwards, towards his plot.
The earth filly shook her head, not that he could see it. “We’ll be okay. These are for foals after all!”
The machines whirred for a few seconds more before it ground to a halt and retracted from their diapers, leaving no obvious change to the foals. The pods opened shortly after, and the two exited with nothing but a slightly mussed-up diaper and wasted time.
“I guess… I guess it was broken,” the colt mused, hopping out of the machine. “It wasn’t even scary.”
Sweet Relief shrugged as she jumped out of the pod. “Why don’t we play a game instead, sissy?” she asked, knowing it would incite a response from Azure.
His lips pursed in annoyance, shifting to a more hostile stance. “I told you, I’m not a sissy. What game?”
“We play ‘you don’t have’ with the stuff around here!” She explains with a grin. “We each find something to put on the other from this room and we put it on the other, claiming that they don’t have that privilege anymore! Ready?”
The colt made a face at that, but he didn’t back down. “I go first!” he said with a grin, dashing off to look for something to take away from his new friend. “Hmm… ah! Here we go!” He returned quickly with a pacifier gag. “You don’t have the ability to talk clearly!” He smiled, affixing the infantile bondage gear around her muzzle, silencing all but the babble.
Not wanting to be outdone, the filly trotted off once the pacifier was in, looking around the room. It was a big room, so there were a lot of things around to play with.
Sweet Relief kept looking around for a long time, unsure about what to choose as privilege to revoke from the colt, until she noticed a spreader bar hidden just behind the diaper pack. Grinning, she returned and held it up. “You dow’t haw da abiwity to mow awound too well!” she said, or attempted to say, around the pacifier, affixing it on the colt’s hind legs, forcing him to waddle further.
Getting into the game, the colt walked clumsily around, unsure about the spreader bar that hampered his movements somewhat. He kept looking around the room, in the hope of finding something he could force onto the filly.
He finally laid his eyes on an oversized swaddling blanket used for newborn foals and smiled. This would make him win, for sure! With a wide grin, he turned back to the pacified filly, waddling profusely. “You don’t have the ability to move at all~”
It took some time, but soon Sweet Relief’s body was enveloped in the binding cloth, unable to move more than a wiggle. With a sigh, she admitted defeat through the pacifier.
“Yes!” Cheered Azure, all smiles. He was stopped, however, by the filly’s whines. It seemed she needed to go to the bathroom badly. However, the colt ignored her whines, and instead proceeded to ask the next question.
“What’s your dare now?” He asked, waddling in circles around the filly.
“W-weww…” she mumbled a little, a little down that he ignored her pleas. It wasn’t like he expected her to use the diapers, right? “You can’t…” She had to look around, unable to move at all, so she had to rely on sight to find something else to use. She then spotted a metallic object, its shape vaguely resembling the average little colt’s crotch. “Mmm! You can’t cum!” She giggled behind the gag, making the colt pale. The thing she was looking at looked suspiciously like a chatisty belt, and cold besides.
However, he couldn’t chicken out now; he needed to win! So, pulling down the diaper a little bit, he slid the belt on and pulled it up. Instantly a shiver went down his spine as the metal was as cold as he expected it to be. He pulled up the diaper quickly, hoping its warmth would clear up the cold, panting a little. “There, now…”
“Where you two have been?” A loud deep male voice called out from outside the nursery. Sweet Relief looked back, and saw a yellow nurse with a light blue curly mane walk in the nursery, an aggressive grin on her face.
“C’mon, follow me now, before you two hurt yourselves!”
Azure Blossom and Sweet Relief, sighed, as they took the gear off each other with the nurse’s help and walked behind the nurse, towards their appointments with their respective doctors.
A feeling of dread began to wash over Azure as he separated from his companion, the same feeling he had at the beginning of the day. He wasn’t sure what ‘Urologist’ meant, but the thought of it gave him the shivers.
“Let’s hope it does not involve what I think it does..” he thought, as he passed the waiting room from where he came.
After a shorter wait, Azure Blossom's name was called out by the nurse, a slender gray pony with light green mane.
The colt took a deep breath, as he walked towards the nurse with unsure steps, forcing an uneasy grin on his face before trotting behind her to the examination room.
The urologist’s studio was rather unproportioned, at least by Azure’s standards of “proportions.” The white and black examination table was extremely large, and a good chunk of the nearby wall was occupied by several pieces of beeping and whining machinery. The doctor, a sturdy and tall unicorn, was light green and had a rust-colored mane, tail and handlebar moustache. He wore round glasses and his coat, which was just a little bit larger than him, was a suspect pinkish colour as if it was immersed a couple of times in blood and summarily washed with only water and soap afterwards.
Azure Blossom’s heart started to beat faster at the sight of the doctor. He didn’t look reassuring in the slightest on his own, and the thought that he was going to fiddle with his lower parts made him even more nervous. But, since he had no other choice, he moved forward towards the doctor, who was compiling papers.
When he was done, the doctor rose his head. His face immediately brightened up, as he slammed the papers down and rapidly walked towards Azure Blossom.
“Oh, you’re here at last!”
“Yes, I am,” Azure said halfheartedly, his face falling, and visibly nervous.
The doctor chuckled as he grabbed him. “Raise your tail and prepare yourself,” he said, setting Azure on the examination table. “Because it’s gonna be a long ride!”
The nurse promptly rolled a tray full of odd instruments towards the examination table. Azure Blossomon looked at them all with a gulp. It went from a long elongated tube, to a spreader, to an extremely long needle attached to a giant syringe.
Azure Blossom felt cold sweat run down his face, uneasily checking the medical instruments laid out in front of him. All the bravado about being a big colt in front of Sweet was leaving at the very sight of the creepy objects.
“Nurse, bring in the saline solution for the sounding IV,” the doctor said with a clap of a hoof.
As he did, the doctor turned to the colt. “Are you ready?” He asked with a slight sneer. “We’re here to check the healthiness of your stallionhood and bladder.”
Azure nodded nervously. The nurse inserted the big needle into a long thin tube and hooked it up to the IV he had brought a few moments before. The doctor took Azure’s sheath with one of his hooves and made a circular movement on the tip with his free hoof, causing Azure to shiver as his rod slowly rose out of its pouch.
Once it was out, the nurse grabbed the needle and inserted the tip of the needle inside the helmet of Azure’s penis, making him yelp and twitch in pain.
The nurse kept pushing further inside his cock, causing Azure further pain and yelping. “I-is it supposed to hurt so much?” He asked, as he bit his lip so to not cry out. The doctor and the nurse only chuckled, saying nothing, which unnerved Azure even further.
Azure felt the tube sliding down his penis, before turning inwards towards his insides. He felt utterly violated by that, but he remained silent, both in the attempt to look like a big colt and because he didn’t even know what was going on- which with silent creepy doctors was something of a major problem.
“I-Is it good?” he tried to ask the doctors after a period of silence, his voice unable to stop shaking.
“Depends on what you mean,” the doctor said just as Azure felt his innards begin poked somewhere. “You mean that it arrived in your bladder? Yes, that’s good.”
He shivered, trying not to think that there was… something in his bladder. “Will it be there for long?”
The nurse opened up the IV’s bag, thusly allowing the clear liquid to start flowing. “It depends, it can last from ten minutes to an hour” the doctor said with a wink. “Although, if I were you, I’d wish it lasted at least half an hour.”
The colt began to moan and squirm, feeling the liquid rush into his bladder and stay there, as if he were peeing in reverse.
The doctor took his stethoscope, putting the round end onto the colt’s lower body, and inserting the ear cuffs in his ears, mumbling about as he listened to the otherwise-imperceptible noises coming from Azure’s body. For his part, the colt squirmed about uncomfortably due to the forced reverse urination forced on him.
“Um… oh gosh…” he muttered, still feeling quite uncomfortable, as he noticed that his lower body was slowly revealing a small bulge that rapidly expanded, stretching his skin. “I-is t-that supposed to happen? Like-e… at all?”
“Actually, yes. It would be quite a bad sign otherwise,” the doctor said, chuckling as he took out a watch from his coat’s pocket. “And the endurance and holding test begins now!”
Azure visibly and audibly gulped as he stared at the tube- now empty again- that was leading deep inside him and that had filled his bladder up. He concentrated in ignoring the discomfort it brought, unaware of the actual consequences of failure but with his mind more than eager to fill in for reality. Images of him peeing himself in front of the doctor and, in a flash, being padded up with a diaper whose size could only mean inability to move- not without great effort in doing so, flew through his head, making the colt fidget a little as he was left to his thoughts.
As time passed on, the colt felt his need to pee grow increasingly intense. He let out a whine, he let his rear hooves tremble and quake, he bit his lip and he felt his heart beat faster. The doctor’s silence did not help matters, especially since he didn’t seem too impressed at the show that he was being given.
“Three and a half minutes in and you’re already squirming around,” he said with a small scary smirk. “That does not bode well for you, y’know? If you give in... ”
The colt gulped again, before resuming his whining, strongly and utterly wishing to ask to the doctor just what was going on inside him. However his discomfort, the doctor’s look and the procedure itself discouraged him from daring to do so, his bravado fully gone by then, fully replaced by fear and insecurity. His heart started to pound in his chest faster and faster as he started to profusely sweat.
Then the unfortunate but inevitable event happened.
Azure felt his bladder expelling a trickle, briefly giving him relief in the release, just before realizing what had just happened to him.
“N-no!” he cried out, as he saw the tube going up his penis being filled with a yellow-ish liquid and as he saw the doctor closing the pocket watch with a frown, all while, just behind the doctor, the nurse was furiously scribbling notes on a notepad.
“You have held your new urine in for six minutes. that’s about as much as a four-years old filly can hold it in.” The doctor said dryly, before bursting into a fit of chuckle, patting the nervous colt’s head. “Of course that doesn’t mean you’re more suited as a filly!”
Azure nervously chuckled as well.
“Yeah… that wouldn’t be too fun…” he said, before taking a deep sigh, while the doctor turned around and grabbed the papers that the nurse was giving him. “What now, doc?”
There was silence, as the nurse ran to a cabinet, opened it and then extracted both a large white and blue can and a box of disposable gloves, which the doctor took with his magic as soon as he finished to scribble on the notes.
“It is time for you to undergo a prostate exam!” the doctor said while he was gloving his right hoof in and while the nurse- in order to make the examination easier- was turning Azure on his back.
The colt bit his lip as he then felt the nurse spreading his rear legs out and spreading some lube around his butthole- followed by the doctor dipping his right hoof into the same transparent lube- which made Azure shiver a little for the cold.
“At my three, I will start the examination,” the doctor set his hoof next to the colt’s asshole. “Is that alright?”
“I- I think so,” the colt mumbled softly with a nod, trying not to look at the hoof and imagining where it was going to go.
“One… two…” The doctor set his hoof real close to the colt’s butthole, but not quite entering in it, until…
“Three!”
With a loud squelching sound, the doctor rammed his limb deep inside the colt’s anal cavity. Azure gasped and whined, blushing strongly, feeling quite violated by the act but also feeling unable to do anything at all about it. He felt powerless and- most likely- he really was.
As he lightly squirmed, Azure could feel the doctor’s hoof worming its way inside him, only stopping when he poked an organ- one that made Azure’s little penis quiver.
“Do you feel anything yet?” The stallion asked, poking Azure’s organ more. “Because I think I’m already touching your prostate.”
“I-is feeling… umm…” the colt blushed and let out a whimper. “y’know… my ding-dong… odd, counts?”
The doctor let out a small chuckle, as the nurse started to pace around the examination table.
“Why, yes, it’s just what I wanted to cause!”
The colt gulped and nodded.
Suddenly, Azure felt something clamping down inside him, sending shivers down his spine and prompting his penis to harden up immediately, causing him to jerk to an uncomfortable position on the table as he was metaphorically standing on the tip of his dick.
“So quick?”
“W-what?” Azure asked, a little nervously. He wasn’t too sure what the question was for, but he doubted he really wanted to know.
“Oh, it’s simple, little one, you seem to get it hard quite fast… almost too fast.” The nurse said with a chuckle, stopping to pat Azure’s head. “You remind me of a certain mare I know, she usually walks the streets and…”
“Nurse Jellyheart, I’ve told you many times to not refer your sexual activity to patients,” the doctor deadpanned, as he kept pinching and feeling Azure’s prostate’s, much to the colt’s embarrassment. “It’s not professional and it may scare them off.”
Azure thought that the nurse talking about his sexual habits was last on the list of things that were scaring him right now.
A few second later, Azure felt all of his lifeforce concentrating onto his dick. He loudly moaned, he squirmed and, finally, he felt release.
“Well… that’s worrying.” the doctor said. “So little sperm produced… even for a colt of your age, that is… disappointing.”
Azure gulped loudly. His heart started to beat faster and faster, as he awaited the verdict.
“W-what is it? I-is it bad?” He asked with a tiny little whine. The nurse let out a roaring evil chuckle, as the doctor rapidly pulled out with a loud plopping sound, much to Azure’s (brief) relief.
“Well, the good news is that you aren’t sick…” he said while taking up the clipboard with his clean hoof, making Azure sigh of relief. “But you aren’t very masculine. I think you should take some strong estrogens and maybe some genital plastic surgery. In fact, we may start right now…”
