Cinnamon Twist gets a scare when experimenting with anal for the first time, so, to ease her fears, she makes an awkward trip to the hospital. Unfortunately for her, the doctor isn't entirely professional in his examinations.

Cinnamon Twist has always been curious about the small hole tucked just underneath her tail; however, she's never been brave enough to try anything. After reading a rather spicy chapter in her latest "romance novel", she finally musters up the courage to stick something up there.

Unfortunately, her lack of experience and the poor descriptions found in her smutfics of how to do it properly cause her to shove things in too fast and too hard with not enough lube and she ends up hurting herself.

Now she's nervously sitting in the hospital waiting room, worried sick that she might have done some sort of permanent damage. Fortunately for her, no actual damage was done.

Unfortunately for her, the doctor discovers this using some... questionable practices.

Version A contains anal, magical medicines, a patient that somehow doesn't question fairly obvious medical malpractice, magically assisted stretching, more stretching, deep stretching, an anal orgasm, somewhat extreme gaping and a temporarily[read: a couple of hours] destroyed ponut. Also, illegal workplace relations.

Version B is a rewrite of Version A but with some more extreme fetishes added in including an absurd level of obliviousness to severe medical malpractice, analingus, anal fisting (hoofing?), anal prolapse (like seriously, it's measured in feet), prolapse fucking, multiple anal orgasms, brief double anal hoofing and complete (though temporary) anal destruction. Also, story spoiler, a brief description of an ass that's been genuinely destroyed at some point in the past.

Reading Version A isn't required to enjoy Version B, and reading Version B isn't required to enjoy Version A. Both versions are self contained, and while I find the differences interesting, you don't have to read both.
Neither version of this story is vanilla. While there is no pain or blood or wastes, this story is not for the casual clopper looking for a light fic before nap time. Especially Version B. You Have Been Warned. Anywho, now that I'm fairly certain I've covered everything important, enjoy!

Version A

It was a bright and cheerful Saturday afternoon, the weather perfect for enjoying the great outdoors. Cinnamon Twist wasn’t enjoying the outdoors, nor had she all day. She was instead squirming awkwardly in a hard plastic seat in the corner of the mercifully empty hospital waiting room, as she had been for almost thirty minutes. Squinting past the harsh lighting, she looked at the small black-ringed clock in the corner of the room for the dozenth time. Not even thirty seconds had passed since she last checked. Glancing up at the white coated nurse manning the reception counter, she nervously did her best to straighten her own white coat as she once again regretted coming to the hospital in the first place. Sure, it had hurt plenty when it first happened, and was still aching gently when she worked herself into enough of a panic to risk going to the hospital, and was still a dull throb when she had embarrassedly murmured why she was here to the completely unfazed nurse at the desk, but now the pain had completely gone. Glancing at the clock again, she wondered if she could slink off and find some place to curl up and die of embarrassment.

“Miss Twist?” Oh. “Could you come here for a second?” Nevermind. It was too late.

Gracefully stumbling off the uncomfortable chair, she reluctantly trudged her way to the front desk. “Yes?”

The nurse deftly shook a large pill out of a bottle and held it out to her over the counter, along with a small cup of water. “This is Clean-Out. Have you ever taken it before?”

Taking the suddenly intimidating pill in her trembling magical grasp, she nodded. “Yeah.”

“Have you taken it in the last 24 hours?”

Cinnamon nodded mutely; her white coated face doing its best impression of the ruddy mane she was trying not to hide behind.

“Do you know how long ago you took it?” The nurse’s dispassionate tone provided a sharp contrast to the practically paralyzing subject matter which helped to calm Cinnamon’s frazzled nerves somewhat.

Glancing at the clock, she did some quick math. “A little over two hours now.” Perfect! Her voice didn’t even shake!

“You should still be good then, but it can’t hurt to take another one. Just remember to avoid taking more than three in a six-hour period.”

Nodding, Cinnamon quickly downed the pill, her brief bout of confidence quickly waning as she realized what taking Clean-Out meant. Before the full implications could settle in, the nurse interrupted her train of thought with an outstretched hoof, pointing at the door to the left of the desk. “Go through that door, Dr. Stable should be waiting for you in the last room on the left.”

“Thank you, Nurse Redheart.” The nurse just waved her off, returning to the small mountain of paperwork on her desk. As Cinnamon turned to head through the door, she missed Redheart quickly gulping down a pill identical to the one she just took.

Halfway down the somewhat short hallway, the pill took effect, causing her to shudder uncomfortably at the strong tingling sensation and sudden emptiness she felt throughout her gut. Swallowing, and steeling herself once again, she continued her measured march to the last door on the left. She managed only a brief pause before knocking, wincing at the decidedly male voice ringing out a cheerful welcome on the other side. “Come on in and make yourself comfortable, Miss Twist.”

The stallion, wearing a long doctor's coat with a small name tag proudly identifying him as Dr. Stable, MD, gestured to the even less comfortable looking plastic stool sitting next to the desk he was seated at. “We’re going to start with a basic health screening, so if you wouldn’t mind holding out your left foreleg…”

She obediently held her leg out, wincing slightly as the blood pressure cuff was firmly cinched on. “Wait, why are you doing this? Isn’t this normally a nurse’s job?”

“We’re always a little short staffed on Saturdays, and I tend to prefer a more… personal touch while dealing with patients. Also, I’m bored. You’re the first patient we’ve had all day.” Pumping the squeeze bulb quickly with his magic, he held his stethoscope to the crook of her leg, listening carefully as he slowly released the pressure. Removing the cuff when he finished, he pulled out a pen and quickly jotted down the results, glancing up as he did so. “Does your family have a history of high blood pressure?”

Put on the spot, Cinnamon blinked, trying to recall. “Uhh, I think my aunt on my dad’s side has it, but I can’t remember if she’s a blood relation or not. Sorry.”

“No worries. Your blood pressure is a little higher than it usually is, but it’s still well within normal.” Picking his stethoscope back up, he stuffed the earpieces back in. “Hold still a moment, I’m going to check your heart-rate and breathing.” Leaning forward, he placed the diaphragm against her sternum, causing her breath to hitch due to his proximity. He politely ignored this, simply staring at the clock on the wall as he counted. After fifteen seconds of near silence, he moved the diaphragm to her right flank, just behind the shoulder. “Breathe in… breathe out…” Moving to her left flank, he repeated his instructions. Leaning back, he took the earpieces out and hung the stethoscope on a hook. “I’m sorry if I make you uncomfortable, Miss Twist. Your heart-rate is a little high. Your lungs sound clear and healthy though.”

“It’s okay. I’m just a bit nervous.” Cinnamon bit her lip, scanning the anatomical posters on the wall in an attempt to avoid eye contact.

“That’s perfectly understandable. Now, if you’ll place this under your tongue until it beeps, I’ll check your ears real quick.” Cinnamon nodded, taking the plastic wrapped thermometer and gently placing it under her tongue. “Your left ear looks good, if you wouldn’t mind turning your head, perfect… This ear looks good too.” Leaning back to record the results, he glanced up at the thermometer as it let out a piercing beep. “Perfectly normal. You’re a perfectly healthy young mare, Miss Twist, so what brings you in today?”

She froze. Her blush, which had been slowly receding, returned in full force. “I, uh, well…” She risked a glance at Dr. Stable, seeing a kind and professional expression on his face as he sat patiently, waiting for her to finish her story. Steeling herself once again, she squared her shoulders, took a deep breath, and started again. “I was, uh, reading a, uhh… book, and I’ve always been curious, and so I decided to try it, so I used my small one, and got it lubed up as best I could, but I don’t have any actual lube, so I just used my own, and I went too far too fast, and suddenly it hurt a lot, like pretty deep in there, and I panicked, and after cleaning up as best I could, I came here as soon as I could, but it doesn’t hurt anymore, but I’m still kinda scared I might have hurt something, or caused damage, or something, but now it doesn’t hurt, so I almost went home, but I’m still afraid-” She finally ran out of breath, gasping for air as she tried to get her furious blush under control.

“Hey. Take a few deep breaths, I’m going to need you to repeat-”

“I SHOVED A DILDO UP MY BUTT AND I THINK I MIGHT HAVE HURT MYSELF!”

Panting from her outburst, she stared at the floor in front of her in shock, dying of embarrassment and wishing nothing more than to sink into the ground.

“Hey. Miss Twist. Look at me.” It took her a second, but she finally managed to glance up into the kind, caring eyes of a medical professional. “It’s okay. It’s perfectly natural to experiment there. You simply didn’t prepare yourself properly.” Standing up, he lowered the examination table as low as it would go. “Now, to make sure that you didn’t hurt anything, I’m going to need to do a visual inspection. If you wouldn’t mind standing up here?”

Her face still burning, she took deep gulps of air as she worked to quiet her racing heart, shakily heaving herself onto the shin high table as Dr. Stable trotted over to a cabinet and pulled out a large syringe. Glancing up at her, he said, “This is Thaumitized Prolaforaminisate B, or, as the over-the-counter version is known, Loosinal. It’s an advanced muscle relaxant and elasticity enhancer that will allow me to painlessly check for lesions and abrasions. Do you have any questions, Miss Twist?”

Gulping, she shook her head, staring at what had to be a cup and a half of ‘elasticity enhancer’, whatever that was. Based on his next words, she could hazard a guess though.

“Now, Miss Twist, if you wouldn’t mind turning around and raising your tail for me...”

Cinnamon stood, frozen to the spot for what felt like hours, staring at the syringe of what could only be described as magic butt lube. Dr. Stable, for his part, patiently waited for her to turn, maintaining a perfectly professional demeanor even as he held four hundred milliliters of magic butt lube in his telekinetic grip. Finally, Cinnamon’s legs unlocked and she slowly turned around, facing the wall away from the door and staring at it as if sheer concentration would cause her to teleport to the other side.

“Miss Twist, I’m going to need you to raise your tail for me.” After a long moment, she managed to will her tail to jerkily flop over her back, exposing her most intimate of areas to a near total stranger. Dr. Stable, making sure she wasn’t watching, took this time to admire her form. Two nearly flat teats were nestled between her hind legs, barely visible as she held her legs together tight. Just above them there was perched a thick pair of meaty ebony lips, still slightly crusty from being soaked recently and not properly wiped off, though they were bone dry now. A small, taught, perineum away rested her tight ponut, a clenching ring of flesh the size and color of an Oreo nestled just below a lightly furred and twitching dock, puckered so tightly that there was no hope of entry. Even as he took it in, the muscled ring relaxed slightly, just to clench so hard that it pulled the skin of her dock with it. Watching for a few more seconds, he marveled at the puffy entrance as it twitched in time with her heartbeat.

Tearing his eyes from the mesmerizing sight, he squeezed a small dollop of transparent goo from the syringe into his telekinetic grasp, bringing it quickly up to her squeezing back door. As soon as the cold substance made contact with her tailhole, she gasped, her tail whipping down on instinct, her dock smearing the substance in as it thrashed about, whipping her long red tail in the startled doctor’s face. Blushing madly, she stammered out an apology as she tried to get her tail under control. By the time she managed to pull her tail back up over her back, Dr. Stable was met with the surprising sight of moisture between her lower lips. Cinnamon grimaced in embarrassment, letting out a small gasp as the skin of her dock and anal ring started to feel warm and tingly, and seconds later she fought to hold back a quiet, strained moan as she felt her tailhole start to loosen, the tingly, warm substance slowly making it’s way deeper into her as her ponut relaxed. Dr. Stable was snapped out of his trance by the soft moan, pulling his gaze from her swelling, dampening lips just as the puffy ring of flesh above it started to unclench, the tightly wrinkled center softening as the muscles lost their tension.

“Are you okay to continue, Ms. Twist?” His eyes never left her softening ring, watching as each small wrinkle slowly smoothed leaving just the permanent wrinkles to gently unclench, widening from sharp gouges to gentle valleys.

After a few seconds of panting, Cinnamon felt adjusted enough to the alien sensation to nod, letting out a breathy grunt of affirmation.

Softly lighting his horn, Dr. Stable began to gently rub the ‘medicinal aid’ into her backside, delicately pulling the ring apart, squishing the relaxant deeper into her loosening depths.

Cinnamon, for her part, groaned and shuddered, the unexpectedly wonderful stimulation proving too much to ignore. A soft moan escaped her lips as her back door was stretched further, allowing the warming liquid deeper into her near-virgin depths. As she felt her anus finally relax, Dr. Stable stopped massaging her pillowy donut, simply holding it slightly open for a few seconds.

Dr. Stable gazed into her darkened depths, admiring the stark transition from the white hue of her coat to the deep grey of her genitals to the fleshy tones of her insides, just barely visible in the pencil-wide gape of her still softening ponut. “I’m going to need you to stay relaxed. I’m going to insert the nozzle of the syringe and on the count of three, I’m going to empty it.”

Cinnamon held her breath as the smooth nozzle slid past her incredibly sensitive ring, the magically stimulated nerve endings in the lubricated flesh of her back door practically burning at the friction they experienced. Against her will, and to her surprise, her nethers clenched in a sudden, powerful wink, spattering the tile floor just as the short nozzle bottomed out inside her twitching passage.

Ducking to the side, Dr. Stable dodged the spatter of natural lubricant, mildly shocked at just how into it his patient was, small streams of almost clear liquid now freely dribbling down her thigh. Shaking his head, he slowly counted, “One… Two… Three”.

Cinnamon groaned at the rush of cool liquid that left fire in it’s wake as it streamed into her butt, her front legs buckling as her hind hooves spread, leaving her in the perfect mating position, presenting everything she had to the world. All embarrassment was gone though, lost in a haze as the new angle allowed gravity to assist in dribbling her new favorite liquid deeper into her canal.

Carefully pulling the nozzle out, Dr. Stable watched as her ponut strained to keep it in, her chemically relaxed muscles weakly clinging to the nozzle and following it out before the heavy lubricative coating did it’s job and let the nozzle slide out, her asshole failing to close after it, left slightly agape as it rhythmically pulsed, as if attempting to close.

Grabbing a pen light from a stand, he pointed it at her twitching ponut, revealing the receding shine off the surface of the goo as it drained deeper into her, dodging once again as she winked once more, her bit sized clit holding itself out for almost half a second. Even as she powerfully winked for a third time, her tailhole never closed, the puffy ring of flesh sagging wider every second as the advanced lubricant did its job.

“Alright, I’m going to begin dilating your anus now, let me know if things become painful or uncomfortable.” A muffled moan was all the response he got, her head resting on her forelegs as her now similarly relaxed dock tried its best to flag higher, even as her tail simply flopped against her back.

Gripping the ring of her ponut, he began to slowly spread her, chewing on his lower lip as more and more of her forbidden tunnel was revealed. Easily reaching a nearly four inch diameter, he changed tactics, halting the spread of her ponut as his magic reached deeper inside, stretching and massaging her rectum as it went.

“Oughh CelestiaaAH!” Cinnamon groaned as she felt his probing magic reaching deeper inside of her, the stretching of her anal walls incomparable to anything she’d ever felt before, the tingling of his magic seeming to chase the warmth of the magical lube deeper into her before, after what felt both like an eternity and not nearly long enough, it finally stopped, feeling like it had opened up a clear shot to her very core. She groaned once again, not caring that she both looked and sounded like the biggest buttslut in the world.

Dr. Stable looked down the long, lubricated, fleshy tube, deep into his patient’s core, having stopped just shy of the bend into the colon. Resisting the urge to reach out and touch it, or to lick the veritable faucet between her legs, he began the slow process of stretching the entire length of her rectum wider, though he paid special attention to stretching her sensitive ponut even more, the ring of muscle having given up the fight entirely. He licked his lips, watching the once impossibly tight orifice spread and stretch until it was a smooth, wrinkle free ring, and then just keep spreading. Once he had reached a diameter of nearly six inches along the length of her rectum, and almost seven at the entrance, he stopped, ignoring the moans of protest from his patient.

Taking to probing along the lower wall of her rectum, ‘accidentally’ massaging her G-spot, he guided the flashlight around her walls, visually and magically inspecting every square inch. “I see no signs of any damage whatsoever in here.” He repressed a laugh, imagining a slight echo as he talked directly into her gaping ass.

“In fact, it looks very healthy in here. I would say that you would have no problems with insertions provided that you properly prepare yourself.” Cinnamon moaned loudly, feeling his hot breath against the walls of her ass, imagining just how close his face would have to be to her oversensitive rear end to be able to breath directly on it. “Do you have any questions before we conclude this checkup?”

She froze, going silent for a half second as she processed the fact that this was the end before wildly thrusting her ass backwards, practically shouting, “Please! Stretch me more! I need it!”

Chuckling, he gazed deep into her quivering rear end, “Alright, if that’s what you want, Miss Twist.” With that, he quickly stretched her rectum to match the width of her ponut, her deep moan of satisfaction telling him that that was indeed exactly what she wanted, the rapid winking of her clit simply providing further evidence. Continuing to stretch the walls of her rectum, he began to magically knead and stroke her ponut, forcing it closed and stretching it open again over and over, earning a loud moan every time.

The feeling of her ponut receiving such abuse was absolute nirvana to Cinnamon. The grinding and rubbing of her sensitive flesh as it was compressed together, followed by the euphoric stretching sensation as it was spread back out again overloading her brain, incoherent gibberish exiting her mouth in a near constant stream. The buildup of tension in her core began to overwhelm her, bubbling forth in the most massive orgasm she’d ever had in her life.

Seeing his patient nearing orgasm, he stopped playing with her ponut, resuming simply stretching it to its absolute max, the faint magical glow of the advanced lubricant when she reached a mind boggling ten inches across letting him know that it had reached the limit of what it could do, her ponut now just a thin, impossibly stretched ring at the end of a now perfectly smooth tube, excepting the gentle swells of her uterus and ovary.

And then she came. Hard.

Dr. Stable received a face full of mare cum, despite his best efforts, even as her orgasmic wail echoed around the small room, her clit launching out and staying out as her entire body locked up. After almost thirty seconds of continuous orgasm, she collapsed, exhausted.

Dr. Stable, having finished what his perverted sense of duty demanded of him, pulled out a cleaning kit, mopping up the mess that Cinnamon had left, cleaning the nearly unresponsive pony herself afterword. She groaned lightly as he carefully cleaned out the entire length of her gaping rectum, even going so far as to carefully scoop the last of the lube out of the depths of her colon, her swollen lips winking one final time as he did so.

As he finished cleaning the examination table, Cinnamon reached back, feeling the edge of the loose loop that used to be her tight tailhole, as if to confirm what she was feeling. Her face suddenly fell, the full extent of what exactly had been done to her ass sinking in. “I’m ruined.” She croaked hollowly; her voice still hoarse from her previous vocalizations.

Glancing over at her with a compassionate smile on his face, he responded gently, “No, you aren’t. Thaumitized Prolaforaminisate B is a forced elasticity enhancer, which means that as soon as the effects wear off here in about two hours, you’ll be just as tight as you were when you walked in the door."

“Really?” She asked, hope in her eyes as she pulled her hoof, which had sunken all the way to the fetlock into her asshole accidentally, out of her yawning cavern.

“Yes, though in some very rare cases, it actually reverts to being even tighter than it was before. Now, is there anything else you need from me, Miss Twist?”

Cinnamon looked around, as if suddenly reminded that this was actually a hospital room that she had just cummed her brains out in. “Uhh, nothing that I can think of.” She stood up, taking a step towards the door before she paused, “You said that this stuff was over the counter?” She blushed and looked away, as if she wasn’t talking to the stallion that had just brought her to an anal orgasm as he stared at the bend into her colon.

“Thaumitized Prolaforaminisate A is, though you’ll find the effects aren’t nearly as strong and they don’t last nearly as long as the hospital use only stuff. It should still be sufficient for your needs though.” He sat down at the desk, starting into the post visit paperwork he would need to fill out, before glancing back up at her. “Oh, two things, if you want to pick it up over the counter, just look for Loosinal, L-O-O-S-I-N-A-L, and it usually comes in a quart size, though you’ll have to pick up an applicator separate.”

“Oh, okay, that works.” She headed towards the door, opening it before he stopped her again.

“And thing two, send Nurse Redheart back, I’ve got a question about where she filed some of the paperwork.”

“Alright, I can do that.” Turning back around, she awkwardly limped back down the hallway, her stiff and sore legs certainly needing a good stretch.

Nurse Redheart glanced up at the sound of approaching hoof steps, rapidly pulling her hoof out from between her butt cheeks, stifling a moan as her hoof drug across the sensitive rim of her ponut one last time. Regaining her composure, she was back to lethargically doing paperwork just as Cinnamon Twist stepped back though the door. Glancing up at her, she asked, “All done?” Cinnamon nodded, a blush creeping across her face. “Perfect. If you’ll sign out here, you’re free to go.”

Picking up the provided pen, Cinnamon deftly signed her name before remembering the task she’d been given. “Oh, Dr. Stable wanted to see you. Something about paperwork.”

Redheart groaned with practiced disgust. “I already told him that I moved those files to the new filing cabinet. Whatever. I’ll be back there when I’m done with these.”

Nodding with satisfaction at a job well done, Cinnamon gave the grumpy nurse her well wishes before turning to the door, unaware that Redheart’s eyes had locked on to her rump the moment she turned around. Redheart almost whistled as she saw the ruined state of Cinnamon’s ass, her drooping tail doing almost nothing to hide the thin, sagging black ring that was all that was left of her ponut, or the six or so inches of intestinal tract you could see before the yawning depths were swallowed in darkness. As she stopped at the door to open it, a shaft of late afternoon sunlight and the swaying of her completely limp tail gave Redheart the perfect view of her entire rectum, down to the bend that signaled the start of her colon. Redheart barely waited for the door to close before her hoof shot back to her ass, furiously mashing against the toy she had left in there all day. Shakily getting up, she walked on three hooves to the door, carefully locking it before moaning loudly. After a few more seconds of furious masturbation, she returned to all fours and let out a breath, before walking over to the window and pulling the blinds apart just enough to peek through.

“I sure hope she doesn’t notice the state that she’s in. Everypony needs a show like that in their life.” Redheart muttered to herself, watching as the mare's gently swaying hips caused Twist’s limp tail to swing far enough side to side to show off everything. Unfortunately, a particularly strong swing caused her tail to brush up against the rim of her destroyed tailhole, causing her to freeze for a second before darting off into an alley. “Damn. Oh well. At least I got a show.”

Turning from the window, Redheart walked down the hallway to the last door on the left, not even bothering to knock as she barged in. “Alright, let’s see this paperwork you’ve got for me.”

Glancing up at Redheart, Dr. Stable wordlessly pulled up the side of his long doctor’s coat and revealed his massive throbbing tool, practically drooling at the tip.

“Aww, did destroying that poor mare’s ass get you all excited? Cause I gotta say, that’s the loosest caboose I’ve ever seen walk out of here. What did you do to the poor mare?” Redheart teased, walking up and trailing the tip of her tail down his aching shaft.

“She asked for it!” He protested, reaching out and telekinetically giving her ass a squeeze, causing her to moan and giggle.

“I could see her colon!” She laughed, licking her lips at the memory.

“Oh yeah? Well I’m about to see yours.” Opening the cabinet, Stable pulled out one of the dozens of identical syringes before Redheart shook her head.

“Not today, you’re not. I brought some normal lube cause I’ve been practicing. I want to take your dick naturally, no enhancements.”

“But I though you loved it when I messed up your guts.”

“Don’t get me wrong, I do love it when you wreck my rectum, but I really want your dick up my ass, and I want both of us to be able to enjoy it. Also, I’m tired of sucking you off after you’re done playing. I want you to blow your load where it belongs.” With that, she turned around and presented her ass to him, flipping her tail up to show the purple object lodged in her puffy hole. Slowly, sinfully slowly, she reached back and pulled out the foot and a half rubber horse cock, leaving her ring slightly gaped as the flare came free with a pop.

“Woah… Wait, hold on, so that’s why you wanted a scan of my dick! You wanted one you could take home with you!” Giggling at the doctor's theatrics, she pulled the bottle of generic lube out from under her hat and held it out to him, but she dropped it as he decided to first see just how deep up her tailhole he could wedge his long, thick, slippery tongue. After five minutes, when he had successfully managed to get his tongue far enough in to lick her G-spot, he retracted his tongue from the quivering mess that used to be his assistant. Grinning, he uncorked the bottle of lube, dumping the entire contents into her upturned ass, dribbling the last few drops around the rim for extra lubrication. After using his magic to knead it in, he mounted her and slowly eased the entirety of his dick into her ass, causing her to let out a long, low moan as the flat tip of his dick straightened the bend at the end of her rectum and just barely squeezed into her colon. I have the best job ever, he thought to himself as Redheart’s clit winked out and tapped his balls twice in quick succession. Nothing could be better than this.

Version B

Author's Note

Just as a quick reminder, Chapter B covers the same story as Chapter A but with more extreme fetishes. Originally, the plan was to keep it near identical until she came, at which point Dr. Stable would let go of her ass, allowing it to fall out. From that point, the differences would start. Unfortunately for me, and fortunately for you guys, I ended up rewriting almost everything. They have the same launch point and similarities in the order of events with the occasional sentence or phrase copied across, but other than that, it's completely new.

Version B

It was a bright and cheerful Saturday afternoon, the weather perfect for enjoying the great outdoors. Cinnamon Twist wasn’t enjoying the outdoors, nor had she all day. She was instead squirming awkwardly in a hard plastic seat in the corner of the mercifully empty hospital waiting room, as she had been for almost thirty minutes. Squinting past the harsh lighting, she looked at the small black-ringed clock in the corner of the room for the dozenth time. Not even thirty seconds had passed since she last checked. Glancing up at the white coated nurse manning the reception counter, she nervously did her best to straighten her own white coat as she once again regretted coming to the hospital in the first place. Sure, it had hurt plenty when it first happened, and was still aching gently when she worked herself into enough of a panic to risk going to the hospital, and was still a dull throb when she had embarrassedly murmured why she was here to the completely unfazed nurse at the desk, but now the pain had completely gone. Glancing at the clock again, she wondered if she could slink off and find some place to curl up and die of embarrassment.

“Miss Twist?” Oh. “Could you come here for a second?” Nevermind. It was too late.

Gracefully stumbling off the uncomfortable chair, she reluctantly trudged her way to the front desk. “Yes?”

The nurse deftly shook a large pill out of a bottle and held it out to her over the counter, along with a small cup of water. “This is Clean-Out. Have you ever taken it before?”

Taking the suddenly intimidating pill in her trembling magical grasp, she nodded. “Yeah.”

“Have you taken it in the last 24 hours?”

Cinnamon nodded mutely; her white coated face doing its best impression of the ruddy mane she was trying not to hide behind.

“Do you know how long ago you took it?” The nurse’s dispassionate tone provided a sharp contrast to the practically paralyzing subject matter, which helped to calm Cinnamon’s frazzled nerves somewhat.

Glancing at the clock, she did some quick math. “A little over two hours now.” Perfect! Her voice didn’t even shake!

“You should still be good then, but it can’t hurt to take another one. Just remember to avoid taking more than three in a six-hour period.”

Nodding, Cinnamon quickly downed the pill, watching in confusion as the nurse took one of her own. This oddity was forgotten moments later as she realized what taking Clean-Out meant. Before the full implications could settle in, the nurse interrupted her train of thought with an outstretched hoof, pointing at the door to the left of the desk. “Go through that door, Dr. Stable should be waiting for you in the last room on the left.”

“Thank you, Nurse Redheart.” The nurse just waved her off, returning to the small mountain of paperwork on her desk.

Halfway down the somewhat short hallway, the pill took effect, causing her to shudder uncomfortably at the strong tingling sensation and sudden emptiness she felt throughout her gut. Swallowing, and steeling herself once again, she continued her measured march to the last door on the left. She managed only a brief pause before knocking, wincing at the decidedly male voice ringing out a cheerful welcome on the other side.

“Come on in and make yourself comfortable, Miss Twist.” The stallion, wearing a short doctor’s coat with a small name tag proudly identifying him as Dr. Stable, MD, gestured to the even less comfortable plastic stool sitting next to the desk he was sitting at. “We’re going to start with a basic health screening, so if you wouldn’t mind holding out your left foreleg…”

She obediently held her leg out, wincing slightly as the blood pressure cuff was firmly cinched on. “Wait, why are you doing this? Isn’t this normally a nurse’s job?”

“We’re always a little short staffed on Saturdays, and I tend to prefer a more… personal touch while dealing with patients. Also, I’m bored. You’re the first patient we’ve had all day.” Pumping the squeeze bulb quickly with his magic, he held his stethoscope to the crook of her leg, listening carefully as he slowly released the pressure. Removing the cuff when he finished, he pulled out a pen and quickly jotted down the results, glancing up as he did so. “Does your family have a history of high blood pressure?”

Put on the spot, Cinnamon blinked, trying to recall. “Uhh, I think my aunt on my mom’s side has it, but I can’t remember if she’s a blood relation or not. Sorry.”

“No worries. Your blood pressure is a little higher than it usually is, but it’s still well within normal.” Picking his stethoscope back up, he stuffed the earpieces back in. “Hold still a moment, I’m going to check your heart-rate and breathing.” Leaning forward, he placed the diaphragm against her sternum, causing her breath to hitch due to his proximity. He politely ignored this, simply staring at the clock on the wall as he counted. After fifteen seconds of near silence, he moved the diaphragm to her right flank, just behind the shoulder. “Breathe in… breathe out…” Moving to her left flank, he repeated his instructions. Leaning back, he took the earpieces out and hung the stethoscope on a hook. “I’m sorry if I make you uncomfortable, Miss Twist. Your heart rate is a little high. Your lungs sound clear and healthy though.”

“It’s okay. I’m just a bit nervous.” Cinnamon bit her lip, scanning the anatomical posters on the wall, most of which seemed to be different angles of the reproductive organs, in an attempt to avoid eye contact.

“That’s perfectly understandable. Now, if you’ll place this under your tongue until it beeps, I’ll check your ears real quick.” Cinnamon nodded, taking the thermometer and gently placing it under her tongue. “Your left ear looks good, if you wouldn’t mind turning your head, perfect… This ear looks good too.” Leaning back to record the results, he glanced up at the thermometer as it let out a piercing beep. “Perfectly normal. You’re a perfectly healthy young mare, Miss Twist, so what brings you in today?”

She froze. Her blush, which had been slowly receding, returned in full force. “I, uh, well…” She risked a glance at Dr. Stable, seeing a kind and professional expression on his face as he sat patiently, waiting for her to finish her story. Steeling herself once again, she squared her shoulders, took a deep breath, and started again. “I was, uh, reading a, uhh… book, and I’ve always been curious, and so I decided to try it, so I used my small one, and got it lubed up as best I could, but I don’t have any actual lube, so I just used my own, and I went too far too fast, and suddenly it hurt a lot, like pretty deep in there, and I panicked, and after cleaning up as best I could, I came here as soon as I could, but it doesn’t hurt anymore, but I’m still kinda scared I might have hurt something, or caused damage, or something, but now it doesn’t hurt, so I almost went home, but I’m still afraid-” She finally ran out of breath, gasping for air as she tried to get her furious blush under control.

“Hey. Take a few deep breaths, I’m going to need you to repeat that one-”

“I SHOVED A DILDO UP MY BUTT AND I THINK I MIGHT HAVE HURT MYSELF!”

Panting from her outburst, she stared at the floor in front of her in shock, dying of embarrassment and wishing nothing more than to sink into the ground.

“Hey. Miss Twist. Look at me.” It took her a second, but she finally managed to glance up into the kind, caring eyes of a medical professional. “It’s okay. It’s perfectly natural to experiment there. You simply didn’t prepare yourself properly.” Standing up, he lowered the examination table as low as it would go. “Now, to make sure that you didn’t hurt anything, I’m going to need to do a thorough inspection. If you wouldn’t mind standing up here?”

Her face still burning, she took deep gulps of air as she worked to quiet her racing heart, shakily heaving herself onto the shin high table as Dr. Stable trotted over to a cabinet and pulled out a large syringe. Glancing up at her, he said, “This is Thaumitized Prolaforaminisate B, or, as the over-the-counter version is known, Loosinal. It’s an advanced muscle relaxant and elasticity enhancer that will allow me to painlessly check for lesions and abrasions. Do you have any questions, Miss Twist?”

Gulping, she shook her head, staring at what had to be a cup and a half of ‘elasticity enhancer’, whatever that was. Based on his next words, she could hazard a guess though.

“Now, Miss Twist, if you wouldn’t mind turning around and raising your tail for me...”

Cinnamon stood, frozen to the spot for what felt like hours, staring at the syringe of what could only be described as magic butt lube. Dr. Stable, for his part, patiently waited for her to turn, maintaining a perfectly professional demeanor even as he held four hundred milliliters of magic butt lube in his telekinetic grip. Finally, Cinnamon’s legs unlocked, and she slowly turned around, facing the wall away from the door and staring at it as if sheer concentration would cause her to teleport to the other side.

“Miss Twist, I’m going to need you to raise your tail for me.” After a long moment, Cinnamon managed to will her tail to jerkily flop over her back, exposing her most intimate of areas to a near total stranger. Looking back, she watched as Dr. Stable took this time to admire her form. Two nearly flat teats were nestled between her hind legs, barely visible as she held her legs together tight. Just above them there was perched a thick pair of meaty ebony lips, still slightly crusty from being soaked recently and not properly wiped off, though they were bone dry now. A perineum away her tight ponut rested, a clenching ring of flesh the size and color of an Oreo nestled just below a lightly furred and twitching dock, puckered so tightly that there was no hope of entry. Even as he took it in, the muscled ring relaxed slightly, just to clench so hard that it pulled the skin of her dock with it. Watching for a few more seconds, he marveled at the puffy entrance as it twitched in time with her heartbeat.

Tearing his eyes from the mesmerizing sight, he looked her in the eyes, setting the tube of clear lubricant to the side. “Alright, I’m going to prep you so that we can get you loosened up for the syringe. If you feel any pain or discomfort at any time, please let me know.” Licking his lips, he leaned forwards, gently kissing her puckered ponut. With a loud squeak, Cinnamon’s tail whipped down, pressing into the back of his head, roughly shoving his muzzle even harder into her back passage. Holding perfectly still, Dr. Stable let her slowly relax, her tail pressing less and less insistently into the back of his head, until with a deep breath, Cinnamon was able to force her tail back up again, giving the doctor enough space to resume working. Gently kissing all around the edge of her protruding ring, he extended his tongue, softly circling the sensitive organ, coating it in a thin layer of his saliva.

Cinnamon shuddered. She’d never been touched by anypony back there before, and now some doctor she didn’t really know was licking her, and it felt… weird. Not bad, per say, just odd. She tensed as she felt him straying closer and closer to the hole in the middle of her ponut, tracing every wrinkle as if he wanted to commit them to memory. When he paused, she was surprised to let out a mildly disappointed sigh.

“I need you to relax so that I can properly administer the elasticity enhancer.” He took another second to take in the sight of her rear entrance, still almost as tightly clenched as when he started, though now covered in a slick layer of spit, the reflections of the overhead lights seeming to dance as the dark skin twitched and flexed, almost as if it was inviting him back in. Heeding the call, he dove back in, lapping insistently at the hole in the middle of her dark ring before resuming tracing the wrinkles, though this time in the opposite direction.

Slowly but surely, she felt her sphincter start to relax, every adventurous press of his tongue at the center of her puffy ring of flesh finding its way a little deeper. She squeaked again as he enclosed her entire ponut in his mouth, his tongue’s efforts redoubling as she clenched tight, before loosening again, just slightly more than before. She repressed a groan, shocked by just how good having her ass eaten like this felt, shuddering once again as she felt him start to suck on her protruding ponut, his tongue drilling insistently into the relaxing center of her ring, worming it’s way deeper millimeter by millimeter until it shot forwards, having wriggled its way past her inner sphincter, the sudden friction causing her to softly cry out.

Thrashing his tongue around as deep as he could in her loosened backdoor for a few seconds, he savored the feeling of the strong muscles of her ponut clenching and squeezing the base of his tongue. Finally pulling his tongue out, he gave a quick kiss to the center of her ring, leaning back to admire the twitching organ, a hint of pink peeking out between every wink of her gently clenching ponut.

Panting lightly, Cinnamon looked back at the doctor, watching him as he stared at her suddenly cold tailhole. A flash of movement pulled her gaze to between his hind legs, causing her to blink at what had to be the largest cock she had ever seen in person bobbing beneath his stomach. Dicks were only supposed to be that big in porn, though she supposed the ponies in porn were real people too. A glint broke her out of her musings, a small bead of pre welling up at the tip of his urethra just to roll off the bottom of his flattened tip, adding to the small puddle beneath him. She watched, mesmerized, as his dark brown, apple sized balls softly jumped in time with his throbbing rod, swaying gently back and forth with his heartbeat.

Finally tearing his gaze away from her winking ponut, Dr. Stable was temporarily distracted by the glistening sheen of her marehood before he shook his head and cleared his throat, looking up at the blushing mare as her eyes were torn from his throbbing member to meet his gaze, before she flinched and averted her gaze, her blush growing even darker.

“Are you okay to continue, Ms. Twist?” She nodded, surreptitiously locking her gaze back onto his heavy balls as he walked to another cabinet, paying no attention as he pulled two foot-long gloves out of an unlabeled box, too busy watching the orbs gently tap against his inner thighs as he stepped up to the cabinet to notice him slipping a small packet into his front pocket. Breaking her stare as he turned back around, she returned to staring at the ground in front of her, trying her best to ignore the trickle of liquid dripping down her inner thigh.

Dr. Stable expertly donned both gloves, tying the included elastic bands around his forearm to better hold them on. Picking the syringe of advanced lube back up, he returned to her now significantly wetter backside, holding back a smirk at the effects his little show had on the now horny mare.

She gasped as he leaned forward and drug his tongue up the length of her marehood before shoving the flexible muscle back into her lightly loosened ponut, swirling the additional lubrication around inside of her cavity before withdrawing his tongue again. “I’m going to need you to stay relaxed. I’m going to insert the nozzle of the syringe and on the count of three, I’m going to empty it.”

Cinnamon held her breath as she felt the smooth nozzle press into her orally lubricated ring, the stimulated nerve endings in the tightly clenching flesh of her back door practically burning at the pressure caused by her tight ring trying it’s best to resist the invader. Against her will, and to her surprise, her nethers clenched in a sudden, powerful wink, spattering the tile floor just as the short nozzle entered her twitching passage.

Ducking to the side, Dr. Stable dodged the spatter of natural lubricant, mildly surprised at the volume of the splat, small streams of almost clear liquid now freely dribbling down her thigh. Shaking his head, he finished sliding the rest of the nozzle into her impossibly tight depths. “One… Two… Three”.

Cinnamon jumped at the rush of cold liquid before groaning at the feeling of intense magical warmth as it streamed into her butt, her front legs shaking as her hind hooves spread, presenting everything she had to the world. All embarrassment was gone though, lost in a haze as the feeling of incredible warmth worked its way deeper into her, far deeper than she’d ever felt anything go before.

Carefully pulling the nozzle out, Dr. Stable watched as her ponut clenched, doing its best to keep the medical lubricant from following the nozzle out, though it began to relax as the effects of the magical goo chemically and magically relaxed her muscles, leaving her gaping slightly, a bead of clear liquid forming at the entrance before rolling down one of the many wrinkles of her twitching tailhole.

Squirting the last few drops from the syringe into the cup of his hoof, he deftly caught the runaway drip with the tip of his hoof, rubbing it into the soft folds of her ponut, the warmth of the spellwork felt even though his glove.

Cinnamon groaned loudly at the feeling of Dr. Stable massaging her twitching ring, the lubricant’s effects obvious as her ponut relaxed and was pulled along with the motions of his hoof, her pussy winking at the intense feeling, feeling a little left out with its only attention being a single lick. Dr. Stable suddenly switched tactics causing her to moan heavily, swapping from rubbing the entire protruding muscle with the flat of his hoof to pressing the tip of his hoof into the center of her ring, firmly rocking it back an fourth in an attempt to spread the ring.

“I’m going to spread you open now, please feel free to stop me if you feel any pain.” He smirked slightly as she simply let out a long, low moan in response, her clit blinking out every few seconds. Returning his gaze to her black ring, he watched as her ponut slowly lost the battle against his hoof, stretching thinner and losing its wrinkles as it gradually conformed to the shape of his hoof.

Cinnamon glanced back at the glove covered hoof just as her ponut gave out, several inches of his limb disappearing into her ass in a moment, forcing the air from her lungs. Gasping, she stared at the leg inching forwards into her rectum, the flat end of his hoof working to push the glob of goo in her gut deeper with every second. She moaned in clear disappointment as his hoof stopped about six inches deep, before grunting at the feeling of his hoof receding, the squishy ring of her ponut being dragged along with, stretching the flesh in a new and wonderful direction.

Pulling his hoof out till the end of his hoof sat just within the ring of her distended anus, he drove forward again, her ponut following his leg into her loosening depths until it seemed to disappear. Repeating the action several times, he would pull his forehoof back until he could see the pink of her internals gripping onto his leg, then pushing back in an inch or two deeper every time.

As his hoof sank deeper than she would have ever thought an object that large could go, she groaned loudly, not caring that she both looked and sounded like the biggest buttslut in the world.

Dr. Stable looked down at her rapidly winking pussy, then back up at the slick ring gripping loosely around the top of his glove, having pushed as deeply in her as he could with his hoof, estimating that he was buried almost to the end of her rectum, the tip of his hoof mere inches from the entrance into her colon. Taking a moment to enjoy the feeling of her clenching walls slowly growing weaker and looser as the lube did its job in allowing him to stretch her far wider than she could naturally handle, he licked his lips in anticipation of what was to come. Pulling his hoof out just as she began to impatiently push back, wanting more of his hoof in her, she sighed in disappointment as his hoof left her rectum with a pop. Admiring his handiwork for a moment, he brought his hoof back up and pressed it against her dripping entrance, slipping in much easier than the first time.

Cinnamon bit her lip as the doctor’s leg drug her ponut into her rectum, stimulating every square inch of the sensitive ring as he slowly pushed until he was just as deep as before. Stopping just as he did last time, he paused for far too long before asking, “Do you want more?”

Her tongue lolled out of her mouth as she groaned a long “Yeeeeesshhh,” rocking her hips back as she attempted to force more of his hoof into her. Pulling his hoof entirely out of her again, he traced around the drooping ring of her ponut before hilting himself again, much faster this time. Throwing her head back, she grunted in time with his thrusts, her orgasm rapidly approaching. “Ah, ah, ah, Ah, AH, AAaauWHOAGGggh!”

Right on the brink of his patient’s orgasm, he withdrew his hoof, shoving his comparatively dry left hoof deep, and carefully pulling it just as he reached her peak, the barely clenching walls of her rectum gripping just hard enough against the rubber of his glove to be drawn out past her loose ponut, nearly a foot of pink flesh exiting her rear end, dangling free in the cold clinic air. Giving her a few moments to recover, he stared at the twitching, swaying length of flesh with barely disguised lust, his turgid cock slapping against his belly at the sight.

When her heart rate slowed enough for her to be able to catch her breath, Cinnamon looked behind her, trying to figure out what was causing the strange, if pleasurable, feeling at her rear end. It took her a few moments to figure out what she was looking at, giving Dr Stable time to gently grab her distended rectum with his magic and begin to inspect it. “I see no signs of damage, in fact, it looks quite healthy.”

Flabbergasted, it took her a few seconds to respond, though when she did, it was with a mix of shock and anger. “Healthy? HEALTHY!? You’ve destroyed my ass!” Taking a deep breath, a look of despair overtook her features. “My ass is ruined beyond repair…”

Magically lifting her chin with a compassionate smile on his face, he responded gently, “No it isn’t. Thaumitized Prolaforaminisate B is a forced elasticity enhancer, which means that as soon as the effects wear off here in about two hours, your ass will be restored to just as it was when you walked in the door.

“Really?” She asked, hope in her eyes as she glanced down at her prolapsed rectum.

“Yes, though in some very rare cases, it actually reverts to being even tighter than it was before. Does that help calm your fears?”

Cinnamon picked up her rectum gently, using her magic to hold it up so that she could stare down the hole at the end. “So, this will fix itself?”

Dr. Stable took it from her with his magic, stroking up and down the length of it, causing her to groan. “Yes. Your ass will be just as tight and beautiful as ever.” Stretching the tip of what used to be an internal organ, he pulled it out just a little farther, until the entrance to the colon was visible at the end. Stroking, stretching and teasing the entire length of her rectum, paying special attention to the perfect circle of her ponut and the wrinkled entrance into her colon, he looked her in the eyes. “Do you want to end this appointment here, or do you want to keep going?”

Cinnamon looked back down to her meaty tube, fascinated by the incredible feelings coming from what her brain told her was deep inside her, despite the fact that it plainly wasn’t. “You’re saying that anything you do to me will go back to the way it was, as if it never happened?”

“Yes. Nothing we do here will be permanent.”

She bit her lip, thinking for a second, before looking him in the eyes. “Ruin me.”

Smirking, he pulled the condom out of his coat pocket. “With pleasure.” Unwrapping the condom, he proceeded to wrap his rock-hard rod, even as he pulled a second syringe out of the cabinet. “You’re still dry in here, so we’re gonna need to fix that. Also, if you wouldn’t mind laying on your back for this?”

Nodding, she gripped her fleshy tube, holding it up as she flopped onto her back before lifting her prolapse straight up for him so that the goo would drain deeper easier. She groaned in shock, then bliss as the cold lube entered her colon, just for the heat to follow afterword. Squeezing her rectum like a tube of toothpaste, she worked her new favorite liquid deeper into her intestinal tract, not stopping until she was massaging her sensitive ponut, her magic faltering at the feeling.

Catching her rectum before it could flop onto her tail, he held it up, lining it up with the tip of his fully wrapped meat, gripping and stretching the tip of her tube even as he reared up and gently placed his hooves on either side of her. “Ready?”

Cinnamon nodded eagerly, groaning loudly as she felt the entrance to her colon stretch over the tip of his massive tool. Looking down her stomach, she watched as the bulge of his lightly flared dick traveled through her intestines, touching places that were never meant to be touched and rubbing against places that were never meant to be explored. She felt the edge of his medial ring press up against the tip of her protruding guts just as the bulge of his tip pressed against her ponut. She threw her head back, unable to contain a whorish moan at the feeling of the simultaneous stretching.

Dr. Stable bit his lip, holding back a groan of his own as he hilted the rest of his dick in her meaty sheath. Merely resting inside for a moment, he contemplated his patient’s words. With a shrug, he figured that she had asked for it. Gripping her prolapse tightly in his magic, he slowly pulled back.

Nearly overwhelmed by the sensation of her guts rubbing against each other, she couldn’t tear her eyes away as inch after inch of his cock was revealed, being followed by yet more of her intestines as they were pulled along with it.

Pulling from her tip with a pop, he admired the extra eight inches of slimy entrails he had pulled from her, the total length of her prolapse nearing two feet. Grabbing yet another tube of lube, he proceeded to empty it into her ruined ass, though she didn’t seem to mind as he massaged it down the length of her prolapse, rubbing her ponut when he got there. Pressing the tip of his dick to the tip of her length, he slowly, but firmly, hilted himself within her guts again, pausing as the lining of her colon reached the end of his condom once again. Gripping the tip of her prolapse, he stretched it out to the sound of a breathy groan before folding it back on itself, much like one folds a sock.

Completely overwhelmed by the new sensation, Cinnamon was reduced to mumbling gibberish, though a string of yesses was easy enough to decipher. Once the wrinkled flesh of her colon brushed the no longer wrinkled ring of her ponut, he began to descend into her depths once again, his tip popping past the ring of her ponut with ease. Tightly gripping her prolapse for a second time, he pulled back, sweat beading on his brow as he neared his orgasm, though his patient beat him there, practically screaming as a liberal coating of her juices sprayed his midsection, trickling down to drip off his balls. By the time his tip popped out of her, nearly three and a half feet of intestinal tract hung out her backside, easily long enough to drag on the floor behind her as she walked, though the trembling wreck that used to be his patient was in no state to walk anywhere at the moment. Giving her a few moments to recover and allowing him to get his rising orgasm under control, he simply stepped back, admiring the state of her ass, gently massaging the length of her massive prolapse. Almost professionally, he took a few moments to delicately manipulate the transition between her colon and rectum, rolling it around in his magic as he watched her come back from her orgasmic state, her eyes slowly regaining focus.

“That… was amazing. Easily the best orgasm I’ve ever had.” She picked her head back up, glancing down past her stomach to admire the state of her prolapse, she was surprised (and most certainly aroused) to see an additional foot and a half of her insides on the outside, the fear of permanency returning, though a small part of her sex addled brain had to admit how hot that prospect sounded. The ability to bring some stallion home and watch his face as she asked him to fuck her prolapse was tempting, the mental image of casually pulling her ponut wide enough for her rectum to flop out, dangling down in front of her imaginary suitor enough to get her hot and bothered again, her clit winking out with a soft shlop.

The quick movement was enough to catch Dr. Stable’s attention, stopping his intestinal massage as he glanced up to her furious blush and far away look. “Are you ready for another round?” Snapped out of her fantasies, she looked up at him and nodded, blushing slightly as a third tube of lube floated out of the cabinet, the nozzle slipping into the end of her prolapse without fanfare as he depressed the plunger, filling her guts with even more lube in preparation for another round of things going deeper up her than they had any right to. Once again, Dr. Stable squeezed the liquid down the length of her prolapse, pausing as he got to her ponut to spend some time stretching it wider and wider, the thick black ring becoming a thin band of flesh, the weight of her prolapse pulling it out from her body. Pausing to line himself up, he hilted himself in a single thrust, not pausing as he once again folded her prolapse over itself, driving deeper and deeper, though he did pause to ponder his next act as the flesh of her colon once again met with the dark ring of her tail hole. Feeling the burning need to go even deeper, he pulled the tip of her prolapse apart as he folded it over on itself again, the abrupt stretching causing her to let out a deep groan, her head falling back against the examination table as the telltale blue glow indicated that the magical lubricant had reached its limit.

As she felt the flesh of her intestines pressing up against her ass for the third time, Cinnamon felt his wide flare pass her ponut just as he let out a grunt, the rapidly filling condom pressing on her still internal walls enough to bring her to the precipice of her third orgasm, her sensitive walls rippling with every jerky thrust he gave. Just as she was about to cum, Dr. Stable’s strength failed him, the sensation of his wide flare passing through her intestines was enough to set her off. She cried out in bliss, the sensation of his tip pulling through her guts, unfolding and straightening them as it went pushing her orgasm to new heights. Even the sensation of the filled condom popping out the tip, her now four foot prolapse slapping wetly on the floor sent a pleasurable shock through her system. Her eyes having rolled into the back of her head in euphoria, she didn’t notice the flash of a camera, nor the click of the latch as the door gently closed again. It was quite a while before she was roused again, the feeling of Dr. Stable gently cleaning the length of her intestines before stretching them open to better clean the insides enough to get her to lift her head.

“Welcome back. How are you feeling?” She blinked at his professional manner, the only sign of his earlier escapades being the gentle twitching of his spent balls.

“I’m… I’m feeling good, a bit worn out, but good.”

“That’s good to hear. Give me a moment and I’ll be able to send you on your way.” Satisfied with his cleaning, the doctor began the slow process of reinverting her guts, causing her to hiss as her sensitive flesh rubbed against itself, unaided by lubrication. Squinting in concentration, he guided her insides back inside until the last inch disappeared past her ponut, the thin black ring doing little to close up after it. “Do you have any questions before you go?”

She hummed to herself, thinking for a moment before asking, “How would I go about getting some of that stuff?”

Dr. Stable smiled, having anticipated that question. “Thaumitized Prolaforaminisate A is available over the counter, though you’ll find the effects aren’t nearly as strong and they don’t last nearly as long as Thaumitized Prolaforaminisate B, which is what we used today. I don’t think the over the counter stuff will be sufficient for your needs though, so I’ll send you with a few syringes when you go, though you’ll need to come back and see me when you need more.” He sat down at the desk in the corner, starting into the post visit paperwork he would need to fill out, before glancing back up at her as she shakily got to her hooves. “Oh, two things, if you want to pick up some Thaumitized Prolaforaminisate A over the counter, just look for Loosinol, L-O-O-S-I-N-A-L, and it usually comes in a quart size, though you’ll have to pick up an applicator separate.”

“Oh, okay. I can probably remember that.” She headed towards the door, opening it before he stopped her again.

“And thing two, whatever you do, don’t mix the two together. Some of the alchemical ingredients don't react well with each other, causing anything you do to yourself to be permanent.”

A brief image of her prolapse falling out in front of her imaginary suiter crossed her mind, but the logical side of her brain told her that the many, many downfalls outweighed the singular benefit. “No mixing, got it.” Heading through the door, she awkwardly limped back down the hallway, subconsciously avoiding the puddle on the floor.

Nurse Redheart glanced up at the sound of approaching hoof steps, rapidly pulling her hoof out of her ruined ass, stifling a moan as her hoof drug back through the sensitive rim of her unlubricated ponut one last time. Quickly regaining her composure, she was back to lethargically doing paperwork just as Cinnamon Twist stepped back though the door. Glancing up at her, she asked, “All done?” Cinnamon nodded, a blush creeping across her face. “Perfect. If you’ll sign out here, you’re free to go.”

Picking up the provided pen in her mouth, Cinnamon deftly signed her name, not yet trusting her magic after her strenuous ordeal.

Redheart nodded, taking the slip of paper and dropping it in her ‘to be filed’ bin. “Feel free to drop by if you need to schedule a follow up appointment.”

Nodding self concisely, Cinnamon gave the bored looking nurse her well wishes before turning to the door, unaware that Redheart’s eyes had locked on to her rump the moment she turned around. Redheart almost whistled as she saw the ruined state of Cinnamon’s ass, her still hiked tail doing almost nothing to hide the thin, straining black ring that was all that was left of her ponut as it struggled to hold the blooming rosebud of her prolapse in. As Cinnamon pushed against the door, still not trusting her magic yet, the effort of pushing a pull door caused her ponut to fail in its valiant effort, her intestines slipping through to plop on the waiting room floor. She froze, seemingly hoping against all logic that Redheart hadn’t noticed.

“Would you like some help with that?”

Cinnamon finally made it home after enduring the most embarrassing ten minutes of her life. Redheart had, using only her hooves and mouth, carefully reinserted her intestines before wrapping her in bandaging in such a way that it looked like a cut on her flank instead of a desperate attempt to keep her intestines from prolapsing past the ruined ring of her ponut. Just as she closed the front door of her single bedroom house behind her though, she remembered Dr. Stable’s offer of a few tubes of Loosinol. Debating with herself, she found herself walking back out her front door, the desire for more of the incredible liquid far outweighing any potential embarrassment, though it’s not like there would really be any. Dr. Stable had shoved his cock up her massively prolapsed ass and had brought her to orgasm three times, and Nurse Redheart had helped her shove her intestines back in after they had fallen out on the floor. How could anything get more embarrassing than that? Opening the front door of the hospital, she noticed that Redheart wasn’t at the front desk. Shrugging, she trotted through the waiting room and down the hall, not noticing the quiet grunts coming from the room as she opened the door and walked in.

“I’m sorry I’m back so soon. I forgot to pick up the…”

Both occupants of the room stared at her, both of Dr. Stable’s forelegs sunk up to the shoulder in Nurse Redheart’s light grey ring. Cinnamon couldn’t help but stare at the nurse’s backdoor, the loose loop of flesh still having wrinkles despite having two of Dr. Stable’s legs passing through it. Her eyes were then drawn to the bulge sticking out just beneath her sternum, the skin of her stomach shiny with magical lube. Returning her gaze to the nurse’s ponut, she was surprised to find that the lube coating Dr. Stable’s bare forelegs had a white, creamy tint to it. She was broken out of her thoughts by Dr. Stable levitating over a half dozen syringes with a small cough. Taking the syringes, she backed out the door, closing it after her. So that’s why Nurse Redheart knows how to hide a prolapse.
