Prologue
This is a direct sequel to my previous chapters - *Sweetie Belle's regret* and *The perversion never ends* Read them first before taking this one on.

Celestia aligned the star above. Fluttershy blinked. Stirring, she turned to witness Sweetie Belle walk up to her bedside. “Hey mom, I kinda need to go to school now… and after, Rarity is going to want to see me.” Dang I’ve overslept - Fluttershy quickly rose - suppressing a yawn In the process. “That’s fine dear, just make sure your back before evening.”

Before the filly could turn, Fluttershy quickly reached out, stopping her and pulling her close. Fluttershy hunched down and affectionately planted a sloppy kiss on the filly’s mouth. And in a nonchalant manner, pressed her tongue inwards. Blushing the filly accepted, opening her mouth, letting the mare do as she pleased.

“Be back soon” cooed the mare. Parting ways, a small string of saliva could be seen in between them. Fluttershy begrudgingly watched the little flank dart out. Standing the mare stretched her legs. Opening her dresser, Fluttershy realized she needed a couple of special items from the nurse’s clinic. There simply wasn’t enough time yesterday to pick them up she thought. Venturing downstairs for breakfast, Fluttershy eagerly began to plan her day out.

Like before Sweetie Belle trotted forth, entering the school building. Greeting friends and sitting down for class as she did. The filly was rather thankful that her hind didn’t hurt; this time around. However she was quite nervous. Would Cheerilee want anything from her today? She thought. Her fears got confirmed when the magenta mare briefly asked her to stay.

“Sweetie Belle you wouldn’t mind helping me organize some pictures, after class would you?” It was obvious what her intentions were. “Y-yeah sure… Cheerilee” responded the filly hesitantly. Apprehension spreading like wildfire within her. This will be the last time…right?

The filly could already feel butterflies wash over her as the school bell rang. The day’s lessons concluded. Yet her private session had just begun. Like previously, Cheerilee began by locking the classroom door and closing the blinders. Before walking up the uneager filly.

“Well now, how are we today?” queried Cheerilee with a smile, as she placed a hoof on Sweetie Belle’s shoulder. “L-let’s not do this” whispered the filly nervously back. Cheerilee simply motioned her downwards. “I want you laying down on your withers. I’m going to straddle your pretty little muzzle; for today’s lesson...

“N-no please, I don’t want to kiss you’re… lady parts again… I don’t like it.” Shaking her head, Cheerilee said “well that’s too bad sweetie.” Before pushing the foal backwards. Sweetie Belle deftly landed on her withers, just like her teacher had requested. Simultaneously Cheerilee quickly towered over her, lowering her hindquarters down.

“I’m not going to lie sweetie. Knowing that this would happen again today. Well… let’s just say I couldn’t resist. I made sure not to wash my hinny for you again.” Cheerilee immediately pressed her lower lips down onto the filly’s. Closing of any further protests.

However this was more than the usual play. Cheerilee moved over the filly’s muzzle, hampering her breathing. Dominating Sweetie Belle in more ways than one.

Realizing that she was unable to breath. The unicorn’s eyes grew wide, struggling, yet unable to budge the big mare on top of her. Cheerilee simply smiled as her subject squirmed below her. Before raising her plot just tad.

In a panicked fit, Sweetie Belle drew in as much air as she could ‘Pwaaa’. “Sweetie if you want to get through this. You are going to have to please me like you did before.” Said the magenta mare mockingly as she returned her plot over the filly’s muzzle.

Buried in between Cheerilee’s neither’s, Sweetie Belle contemplated her harsh situation. Unable to properly breathe with no possibility of escape. Meant that only one real option persisted. Opting to do as asked, the filly uneagerly rolled her tongue out. Pressing it on the aroused sex before her.

In her flustered state she hadn’t quite noticed the strong smell deriving from Cheerilee slit. Focusing at the task at hand, it became rather clear. The musty smell lacked any pleasant notes. Hints of sweat and dried urine combined with the mare’s arousal was all but prominent. Revolted she gagged in her mouth. Not sure, if she was going to be able to this.

Unpleased with her progress, Cheerilee motioned her haunches forward. Completely suffocation the filly below. Taking the hint Sweetie Belle started licking the marehood back and forth. Knowing that she wouldn’t be released if she didn’t.

“Mmm, yes… that’s a good girl,” grinned her teacher, “make sure you make me nice and clean down there.” Whimpering the filly continued on. Fighting the awful taste, trying not to choke up.

Smiling the mare reached down and spread her labia apart. Making sure the filly reached her deepest parts. “I could… ‘mnh’, I coul– ‘pha’, do this forever ‘aha’.” Moaned the mare lustfully. Nothing gave her greater pleasure than forcing little filly’s to eat her out. The humiliation they suffered alone - was enough to get her off. Seeing foals writhe under her never got old.

The illicit taste continued to flow with every second. Sweetie Belle struggled not to swallow too much of her nectar. Wanting to be anywhere in the world but here. Reaching up, she parted her lips from the hole below and placed them on top of Cheerilee clit. Sucking away at the nub. Pleasuring the mare in every way she knew. Hoping to end it faster as she did.

“That’s right baby, make sure you clean beneath my hood.” The mare lifted her clit hood up, allowing for better access. Twitching as the filly sucked away, milking her of everything she got. “I swear you ‘ahhn’ are getting ‘mnh’ better at this!” panted the mare, tensing her haunches.

However the mare wanted more. More of everything. Thinking of no better way to humiliate the unicorn. Cheerilee slowly leaned her withers back. Motioning her pussy far forward, thus replacing it with her tailhole instead.

The filly noticed the small change in position. Instead of her pussy, she was now staring up at her butt hole. She can’t… does she want me to... Before she could fully comprehend the situation. Cheerilee pressed her plothole down on Sweetie Belle's slick muzzle. The mare was firmly holding her down by this point. Not taking any chances.

Stunned and disgusted, Sweetie Belle began protesting by thrashing about. “Aw c’mon now. Don’t disappoint me now” edged Cheerilee on. Not able to take much more of this. The filly squirmed, struggling to get away, yet was unable to. Looking up all she could see was her teacher’s asshole. Reluctantly and cautiously she ushered her lips forward. Expecting the worst.

Closing her eyes, the filly surrounded Cheerilee’s star with her lips. Taking a moment before anxiously bringing her tongue out. And in a circular pattern, she slowly began licking around the hole. “That’s the way! See you can if you just put your mind to it.” Chuckling the mare leaned back, taking in the new wave of pleasure.

The new bitter taste didn’t exactly reassure Sweetie Belle any. Her dignity utterly destroyed. Yet too defenseless to do anything about it. The mare had her pinned down. There was no respite to be had. Just endless humiliation as she lapped away at the glistening hole.

After a while Cheerilee began alternating between her pussy and ass. Forcing the filly to clean her out both ways. “’Ah’, ’ahn’, ’aha’ I’m getting close Sweetie!” could be heard. The mare moaned vigorously. Tightening her hindquarters, and with a love strained voice; sharply cried out ‘Aahhhhaa.’ Spraying the filly down with her love juice.

‘Hah’, ‘hah’, ‘hah’ panted the mare satisfied. However like previously, she needed more. “That was lovely sweetie… just hold still - here comes your reward.” Said Cheerilee as she held her down. Prying her lips open with her front hoofs. Cheerilee lined her marehood up with Sweetie Belle’s mouth. And began releasing a steady stream of warm yellow liquid down her throat. Peeing directly down her esophagus.

Slow to react, and in shock, Sweetie Belle wriggled her head sideways. Trying to get away. Having preempted this, Cheerilee simply closed her haunches fully. Holding her in place. Making sure the filly took most it down before spilling the rest on the floor.

Choking and coughing, the filly was released from her prison. Distraught she quickly staggered up. Blinking and clearing her eyes for a moment. Turning she saw Cheerilee exit the classroom whilst saying “I’m going to get a mop, I’ll see you tomorrow for class.” Grabbing her saddlebag, the filly darted out.

While outside Sweetie Belle quickly trotted over to the nearest bushes. Trying as she may, she was unable to throw up. Gagging and heaving; yet not quite able to hurl anything up. Defeated she began walking home. Hoping she could sneak inside without Rarity noticing.

A short walk later and Sweetie Belle had found herself outside the Carousel Boutique. Taking a moment and regaining some composure. The filly stealthily peered through the windows. She was relieved to see Rarity in kitchen eating a sandwich.

Opening the front door, Sweetie Belle quietly slipped into the boutique. And proceeded upstairs into the bathroom. Showering she began to relax. The hot water poured down on her stained fur. Washing her clean. Reaching for a towel, the filly dried herself briskly before venturing downstairs. Rarity hadn’t seen her at all yesterday she realized.

Ventured to the kitchen and acting like nothing was out of ordinary. Sweetie Belle’s greeted her older sister with a smile. “Hey sis! How are the new dresses coming along?” Looking up Rarity indifferently stated “fine, fine dear, how’s school?” The mare quickly returned her eyes to the fashion magazine she was reading.

Lying Sweetie Belle said “all good, I’ll be heading over to our clubhouse later. I’ll just eat something first.” Nodding - Rarity flipped another page. Usually her big sister’s apathetic ways would annoy her. However this could sometimes turn into an exploitable strength; like today for example. Whenever Sweetie Belle wanted anything done quietly. She could always count on Rarity for not prying into any details. Too busy with herself like always...

After finishing her lunch the filly marched steadfast over to Fluttershy’s house. Bracing herself for her next encounter. Taking solace in it being the last. No matter what, Sweetie Belle could never quite anticipate what Fluttershy would do. Which didn’t calm her nerves as she walk onwards.

Reaching her destination, the little unicorn hesitantly knocked on the pegasus door. Hoofsteps echoed inside. Shortly after Fluttershy opened the door. Greeting and motioning the filly inside. Whilst simultaneously locking the door behind her.

“Welcome back sugarcube,” smiled Fluttershy, “ready for some fun time with mommy?” Not sure what to expect, the filly sighed and answered “y-yeah I guess so…” The mare placed her hoof below the unicorn’s muzzle, while lustfully saying “head on upstairs sweetie, I’ll be right with you.”

Moving upstairs with heavy steps. Sweetie Belle feared the worst as she entered her least favorite bedroom in the world. It didn’t take long for Fluttershy to reappear. This time around she didn’t carry anything with her. “All right honey, go ahead and lie down on the bed for me.” Fluttershy motioned her forward. Uncertain Sweetie Belle looked up. Smiling the mare continued “go on now.”

Doing as told, Sweetie Belle climbed up on the bed, lying down as instructed. “Good now hold still.” Reaching to the nightstand table, Fluttershy withdrew two short ropes from the drawer. The filly grew ever nervous seeing the ropes “w-what are you… going to do to me?”

Leaning in Fluttershy spoke “I’m just going to tie you down. Don’t worry, it won’t hurt.” Taking the rope, the mare started looping them around Sweetie Belle’s front hoofs. Before tying them to the forward-facing bedposts. Content she couldn’t escape, Fluttershy took the second rope and encircled her hind legs. However instead of tying them on the next set of bedposts; at the foot of the bed. She pulled forward, tying them on the same posts that her front hoofs were on.

Subsequently she pulled Sweetie Belle’s hind legs up and over. Exposing her neither’s completely. Sweetie Belle began to complain “t-this position... is way too embarrassing mom!” Ignoring her Fluttershy reached for the nightstand table again. Withdrawing a simple muzzle gag and fastening it on the filly. Locking the small straps behind her head.

“There all nice and secure.” Grinning the mare rubbed her haunches together in lust. “Yesterday after playing with your little behind all day. And seeing how stretched you had become. Well… I just thought we could try something a little bigger. Knowing you would protest a lot, I figured the only sensible thing to do, would be to tie you down.”

Grabbing a bottle of lube from the drawer she continued “it’s going to get a little intense now sweetie. If you want to cry that’s fine. Nopony is going to hear you with that gag on.” Placing herself on the bed just behind Sweetie Belle. Fluttershy began smearing the lube on her right hoof. Making sure the filly saw. Before reaching forward and pressing her hoof on the puckered hole.

Eagerly she circled the foal’s soft tailhole, loosening it up bit by bit. The filly under her moaned and squirmed as she worked away. After a minute or so, the pegasus reached behind her own hindquarters, and extracted the small pink dildo. The same one that she had used on Sweetie Belle previously. It had been lodged in her pussy all day. Teasing her gently as she walked around Ponyville.

Bringing the toy forward, she brusquely pressed it on the filly’s plothole. Squeezing it inside, stirring her further. Tugging the toy in and out rapidly whilst listening to the sweet grunts below. “I’m assuming Cheerilee had her way with you again today no? She won’t bother you in the future... if you don’t ask her to of course.”

Pulling the toy completely out, the mare replaced it with her right hoof. Applying more lube to it, she pressed forward. Slowly trying to edge it in. Almost she thought, just a little more. Standing, she quickly walked over to her desk, withdrawing a metallic speculum. “The things you can get from the nurses clinic nowadays.”

Takin the speculum, the mare carefully drove it inside Sweetie Belle’s loosening butt hole. Smirking as she started turning the small notch, swiftly expanding it. Stretching the filly open. Strained Sweetie Belle groaned loudly ‘gafh’ as each notch was turned. However Fluttershy didn’t stop until she hit an impasse. Leaving it still and gazing down. She could see that Sweetie Belle was reasonably clean inside. Not surprising as she had evacuated everything she had yesterday.

With an evil smile Fluttershy began turning the notch once more. The filly started wriggling in discomfort. One turn, two turns, three turns - slowly but surely. Her tailhole was forced to expand to new heights. Leaving her expanded for a moment, Fluttershy grabbed the lube and poured most of the contents down into her gaping hole. The cool substance caused the filly to tense up.

Returning to the notch, Fluttershy rotated it one last time. Before compressing it fully. Retracting the tool she quickly lined up her right hoof. Pressing firmly on the filly’s stretched anus - it slowly gave way this time. Her hoof was sinking inside. The warm embrace continued to resist her intrusion. Not halting she began twisting and jerking it. Beckoning her hoof down further in the process.

Sweetie Belle suffered greatly. Tears streaming down her face. Completely stunned by pain and discomfort. Unable to do anything but wiggle and grunt as Fluttershy eased her hoof into her bottom. The feeling was unbearable. She tugged at her ropes, trying desperately to break free.

Fluttershy slowed down, content when she saw that a quarter of her hoof was buried deep inside. “There that should do it.” Leaving her hoof inside for a good minute, before slowly retracting it. “This is just warm-up dear.” Withdrawing entirely, Fluttershy reapplied the rest of the lube on her hoof. Before bringing it back. Carefully sliding it in, this time somewhat faster. Motioning her hoof back and forth as she did.

It had taken a long while to get to this point thought Fluttershy. However it wasn’t the destination that was important. Like always, it was the whole journey - the entire experience that mattered. Like previously she began pulling back, withdrawing her hoof. Before plunging it back inside. Each time thrusting faster and stronger.

Working up a good rhythm, the mare started pumping in and out repeatedly. Her own pussy dripping with excitement as she hoofed the little filly’s backdoor. Feeling the strained back passage loosen further with every tug and pull.

Sweetie Belle’s agonizing treatment gradually turned less painful over time. Her ass slowly relaxed to accommodate the massive girth. Yet it was all still far too uncomfortable and arduous to yield any real pleasure. The immense pressure reminded her of the enema she had been forced to take.

Grunting and squirming fervently whilst shaking her head sideways as to say ‘no’. The filly bit hard into the muzzle gag. It seemed nothing she did alleviated her current situation. Giving up on the ropes she slowly began accepting the now rigorous thrusts from Fluttershy. Not clenching her tailhole, was about the only thing that helped.

The warm hole persisted to protest slightly. However only slight resistance could be felt. Ominously grinning, Fluttershy began slamming her hoof in and out rapidly. The new pace slowly changed something in the filly. Instead of just painful grunts. Small but delightful whines could be heard through the gag.

“Mmm, does sweetie like that? It’s okay, just relax your little tush for me. It will feel good in no time I promise.” Changing her pace again, Fluttershy started doing long powerful thrusts. Almost pulling completely out before ramming home. The filly couldn’t help but arch her back up. Her bottom being penetrated wholly and aggressively with no respite.

Her body no longer felt like her own. Strange conflicting emotions incessantly swept over Sweetie Belle; confusing her young senses. The unmistakable hint of pleasure building within her. A warmth that was impossible to deny. Embarrassed she began moaning through the gag.

This was just the cue Fluttershy had been waiting for. Smiling she pulled out completely. Leaning forward she unhooked the muzzle gag. “’Ahn’, ‘ah’ w-what did… ‘mnh’ you stop for? I was g-getting close…” said Sweetie Belle bewildered. “Oh, so you want more?” answered Fluttershy slyly.

Catching herself, the filly just realized what she had asked for. “N-no… I umm…” Amused Fluttershy leaned back, placing her hoof on the filly’s tailhole. “C’mon now sweetie, ask for it like a good foal.” Teasingly she encircled her gaping hole.

“I… I,” with a heavy blush Sweetie Belle stammered, “p-please continue…” Fluttershy barely able to hold herself back. “’Hmm’… no, you are going to have to ask better than that.”

“’Ah’ p-please, ‘hah’ put your hoof back… in my… rump.” Happy to oblige, the pegaus squeezed in. ‘Ahhhn’ moaned the filly, feeling the large hoof return. Brusquely the mare began hoofing her mercilessly.

“See... being with me isn’t all bad.” Taunted Fluttershy. Gritting her teeth Sweetie Belle braced herself. The heavy pounding was unrelenting. The strange fullness and the immense pressure; drove her closer and closer.

“G-go a little s-slower, ‘gah’ please mom!” cried the filly. Picking up the pace Fluttershy rammed even deeper than before. Working her hoof further down; trying to get as much in as possible. Stretching the filly to new dimensions.

Sweetie Belle began to shake, tensing her haunches slightly. “I… I, I’m ‘aha’ going to…” At the last moment Fluttershy quickly took her left hoof. Placing it over the filly’s little clit. Rubbing her off like crazy. Overwhelmed Sweetie Belle screamed ‘AHHHaaahhnnn!!!’ Cumming hard like never before. Spraying her love juice all over Fluttershy. Riding her orgasm out, Fluttershy continued to rub and hoof Sweetie Belle. Until she ceased writhing all together.

‘Hah’, ‘gah’, ‘aah’ panted the filly. Spent she relaxed in her ropes. Without warning Fluttershy began pulling out. Slowly, taking her time. Feeling the warm albeit loose insides surround her hoof. Before retracting it fully. Sweetie Belle hardly even noticed.

The pegasus proudly stared inside the gaping hole she had caused. It could always be bigger… Content she leaned over and untied Sweetie Belle’s ropes. Bringing her hind legs carefully down. “So… how was your first hoofing? I wasn’t too harsh on you, was I?” Said the mare somewhat sincere.

Not sure what kind of answer Fluttershy wanted. Sweetie Belle simply replied with “It h-hurt a lot at first… but 'hah' then I… k-kinda got used to it I guess…” In a motherly fashion, Fluttershy reached forward and embraced Sweetie Belle. Hugging her close. “That’s a good girl.”

Letting Sweetie Belle rest for a while, the mare started preparing the next phase. Gathering the various supplies she had purchased from the nurses clinic beforehand. Fluttershy excitedly entered into the bathroom. Filling a rather large enema syringe. Before venturing back to the resting filly.

Turning Sweetie Belle saw Fluttershy walk up to her with the new goods. “An e-enema again?” murmured the filly unhappily. “No honey, this isn’t for your butt.” Was all the mare said, before connecting a rather lengthy tube to the end of the syringe.

“I’m not going to tie you up this time around, I trust you won’t do anything to upset me.” As she spoke Fluttershy patted the filly’s head to reassure her. “I bought this small gown for you today. It’s pretty enough even for Rarity’s taste. It will help cover your rather, ‘ehem’ opened hind - for when we leave.”

“But first let’s prepare.” Fluttershy took what was left of the lube and applied some to the tube end. Bringing the tube up, Sweetie Belle could see that the end of it, tapered off. “Do you know what this is called sweetie? It’s called a catheter, you see this small narrow end? This part goes into your pee hole.”

Nervously Sweetie Belle asked “a-are you sure it’s safe to–“ Cutting her off Fluttershy stated “hush now - I know you can handle it just fine.” Taking the tapered end and aligning it with Sweetie Belle’s urethra. Fluttershy carefully eased it in. Motioning the tip slowly - and with the utmost care - forward.

Not liking the new sensation the filly yelped ‘mnaa’ as Fluttershy coaxed the tube further inside her small canal. Closing her haunches in protest. “Now now, be a good little filly and open your legs for mommy.” Uneagerly Sweetie Belle spread her legs. As she did, Fluttershy inserted the last half centimeter inside.

“There, all done, how does it feel?” asked the pegasus. “I-it kinda b-burns a little” replied the filly. “It will go away in a bit, just hold on dear” continued Fluttershy calmly. Reaching next to her, Fluttershy took the syringe. And without delay, pushed on the large syringe handle.

‘Gasp!’ exclaimed Sweetie Belle. Closing and grinding her haunches together. The filly tried to stem the flow but nothing helped. “P-please… I was already full… n-not so much mom…” Giggling the mare halted momentarily. Allowing Sweetie Belle to adjust for moment. “I bet you’ve never felt something quite like this before?”

However there was no visible bulge yet. Thus Fluttershy continues to pour in more. ‘Nghh’ could be heard from Sweetie Belle as she took more inside. “There there, that’s a good filly. I want you to take as much as you possible can.” Said Fluttershy tenderly. “But I’m already 'ugh' so full mom… no more p-please!”

A bulge was starting to form just beneath her stomach. “No… not quite there yet sweetie, sorry” returned Fluttershy, as she depressed the handle again, causing another steady stream. The little unicorn began squirming as the onslaught carried on.

“I-I really don’t think I can… take…” Halting her ministrations, Fluttershy placed the syringe down. “That should do it. Let me just disconnect the catheter end from the tube. Then we can head out.” Working fast, Fluttershy unscrewed the tube part from the end piece. Leaving Sweetie Belle plugged. “It’s truly amazing how these new catheters work. As I fill you with water. I simultaneously inflate a small retention balloon inside with water. It’s super hard to deflate by yourself. But that’s kind of the point.”

“But h-how am I going to pee with this in me then?” questioned Sweetie Belle anxiously. “You’re not,” answered Fluttershy lovingly, “we are going out for a walk, make sure you put on the gown before we leave.” Hesitantly the filly said “N-no... m-mommy I can’t go like this…”

“’Hmm’ and who do think is going to deflate the catheter in you? Your sister? Or perhaps Twilight?” What would you tell them? They wouldn’t believe anything you said. Besides if word got out, your entire school would laugh at you nonstop. Do you think Cheerilee is going to back you up, if that ever happened?”

“Get dressed and meet me downstairs in five.” Defeated the Filly did as told. No matter what, Fluttershy always had good counterarguments. It’s true, who would believe her instead of Fluttershy? She thought. Pulling the gown over her, the filly drudged downstairs.

Leaving Fluttershy’s house both ponies headed to the park area. The park was overlooking a small lake - the only one in ponyville. As the sun was beginning to sink, the water playfully reflected the last rays of light. Cascading them both as they walked along the cobblestone pavement.

“How are you holding up Sweetie Belle” asked Fluttershy. “It’s r-real bad mom, it feels like I’m… going to explode if I don’t pee.” As the filly spoke, she began clamping her hindquarters together, stressing her gait. “You can relax dear, I want you walking like normal. Nothing is going to leak out.”

“It’s not because of that,” replied Sweetie Belle, “It’s uncomfortable, I can’t help the clenching.” Not many other ponies were around, the only ones there were on the opposite side of the lake. Thus Fluttershy reached down and lifted her gown up. Exposing the filly’s stretched tailhole. It still hadn’t closed.

Never miss an opportunity the mare thought. “W-what are you doing? There are others here? Whispered Sweetie Belle concerned. “I want a good view, besides there are no ponies here right now.” Humiliated Sweetie Belle was forced to openly flaunt her behind.

The new fullness inside was already getting to her. Small pangs of pain shooting through her. Making her spasm and clench involuntary. This is getting bad...

After walking for ten more minutes and nearing a bench, Fluttershy decided they both needed a pause. Sitting down the mare brought her hoof up. Opening her muzzle she dribbled several drops of saliva on it. Before reaching under Sweetie Belle, placing it on her butt hole.

“Y-you can’t be serious... not now… not here… not like this p-please.” Whimpered Sweetie Belle. “Hush dear, let mommy have her fun.” It came as a surprise to Fluttershy. But after fondling Sweetie Belle for a good five minutes. She managed to squeeze her hoof inside once more. Obviously Sweetie Belle was still quite stretched from before.

“Oh my... I didn’t quite expect that.” Said the mare gingerly as she began pulling in and out. Gently hoofing the filly, trying not to cause too much discomfort for her. Sweetie Belle did her best not to let any noises out. Gritting her teeth and moaning lightly as Fluttershy pulled her large hoof out of her ass. Feeling the outer ring flex before jamming it in again.

At that moment two ponies neared them. They walked closer and sat down on the bench opposite to them. Sweetie Belle didn’t recognize them at all. Both of them looked like they came straight from Manehattan. Friends of Rarity maybe? Here on business? Sweetie Belle quickly noticed that Fluttershy had stilled her hoof.

However seeing the two earth ponies in front of them settle down. Withdrawing various trend magazines and quietly keeping to themselves. The filly could feel Fluttershy softly start thrusting again. This time pushing far into her ass. The new pressure combines with her extreme need to pee - elicited a small yelp.

Yet the two mares in front of them didn’t seem to care. Like Rarity they were too busy browsing their magazines. So this doesn’t just apply to my sister then she thought to herself. Annoyed yet thankful it was the case for now.

Fluttershy impressed by Sweetie Belle endurance, started sliding her hoof in and out. Feeling the slickness inside meant that plenty of lube was still present. The open benches allowed for half decent access.

Sweetie Belle audibly groaned 'mngg' as Fluttershy methodically hoofed her behind. Quickly she disguised her pleasure with a cough. Earning her a quick, albeit uninterested glance from the two mares.

Fluttershy loved taking long strokes. Whenever she retracted her hoof completely out. She purposely lingered on the puckered hole before firmly pressing inside. Not stopping until the bench constricted her.

Sweetie Belle desperately needed to pee. As she felt Fluttershy’s hoof slide in and out. It viciously pushed on her bladder. It took all she had to just sit upright. Brining her small hoof up, she deftly wiped the sweat from her forehead. And with a fake smile she continued to endure.

Unexpectedly both mares swiftly rose from their seat. Seemingly having finished their read. They started walking downhill. Leaving only Fluttershy and Sweetie Belle. Out of range Sweetie Belle let out a load moan. “’Ahhnn’. W-was all of that ‘aha’ really necessary?” asked the filly irritated.

“Well… it took your mind of the retention didn’t it?” answered Fluttershy slyly. Pulling out and leaving her gown up, Fluttershy motioned the filly to follow her into the parks only public restroom. Previously there were only three outhouses here. However ponyville’s recent popularity had led to an increase in visitors. Thus these new facilities were built to help facilitate any guests. Several small changes like them had occurred all around of late. For the better Fluttershy personally believed.

The pegasus quickly checked the five stalls, making sure nopony was in them. “Finally” said Sweetie Belle out loud. “P-please remove… this, will you?” Turning she exposed her flanks to Fluttershy. Sadly for her, it seemed the mare had other ideas in mind. “Oh no… not yet sweetie” responded Fluttershy daintily. “Huh? Then w-what are we doing in here for?”

Reaching into her saddle purse. Fluttershy pulled out a medium sized syringe. She pulled the syringe handle out completely. Settling it on the sink. Parting her hind legs, she brought the tube opening next to her marehood. And with restraint, she released directly into it. Before replacing the handle to it.

Sweetie Belle was about to turn to face her. However she was halted. The mare held her in place with her left hoof. “No! p-please don’t put any more in… I’m begging you don’t!” cried the filly. Ignoring her pleas Fluttershy connected the syringe onto the protruding catheter end. As she did, she immediately pressed down on the small handle. Releasing the warm liquid inside her already straining bladder.

Stomping with her front hoofs and whimpering 'mnhhuh'. The filly thought she was about to burst from the pressure. However nothing came out - no matter how hard she tried. “Don’t even try… the catheter has a small valve in it. You won’t be able to pee unless I want you to.” Stated the mare playfully.

“Just one more should do the trick.” Repeating the process, she quickly refiled the syringe with her own. Before connecting it back on. Filling the filly up once more. Shaking Sweetie Belle begged and shouted “I can’t t-take any 'gahh' more! Please!”

Feeling a fair bit of resistance Fluttershy stopped. Before sadistically squeezing in some more - for good measure - before pulling out. Emptying the rest in the sink. “There all done… you can pee when we get home.” Trembling and sweating Sweetie Belle said “I-I c-an’t, I need… I n-need…”

Bringing her hoof to the filly’s muzzle, Fluttershy made a ‘hush’ noise. “You’re doing great, just hold on for a little longer okay?” Before she could answer, Fluttershy motion her outside. Pulling her gown down - both ponies began walking home. Even with the dress on, the inflated bulge could be seen realized Fluttershy.

The trek back was grueling. Sweetie Belle struggled and shuddered all the way back. Stopping once or twice as the discomfort became too much for her. Each step reminding her of her predicament. The filly impatiently squeezed her haunches tightly as they neared Fluttershy’s house.

Entering inside Sweetie Belle nearly collapsed on the floor from exertion. Panting and sweating profusely. “That’s a good filly, come along now, let’s get you upstairs.” Said Fluttershy as she helped her upstairs into the bedroom.

Bringing Sweetie Belle down on the bed. Fluttershy simultaneously reached under it, withdrawing a white diaper. The filly didn’t even protest this time around. She just turned her head slightly to the side. Trying to hide an embarrassed blush as Fluttershy began fastening the nappy on her flanks.

Before Fluttershy fastened the top cover she ventured into the bathroom. Filling the medium sized syringe with water. Before bringing it back to the filly. Leaning over, she made sure Sweetie Belle didn’t see her reattach the syringe on the catheter end.

Sweetie Belle too strained and tired to notice much. She simply laid back, trying to relax. Waiting for Fluttershy to finish attaching the diaper. Unbeknownst to her Fluttershy was slowly pressing down on the syringe handle. Filling her ever so slightly. Topping her off.

The filly began quivering prominently as Fluttershy pressed a quarter of the water inside. “H-hey are you d-done yet? I really… n-need to go…” The mare mischievously said “sorry dear, I'm just having some trouble with the catheter.” For fun Fluttershy pulled the syringe handle back. Extracting the yellow liquid. Before slamming the handle down. Resulting in a sharp cry 'ahhn' from Sweetie Belle.

“Oh sorry, these catheters are more complex than I thought.” As she spoke she withdrew the handle once more. Like previously she slammed it down hard. Causing Sweetie Belle to jolt up slightly. “’Hmm’, yes almost got it now.” Doing the same again she retracted the syringe and forcibly pushed inward. This time making Sweetie Belle twist sideways in agony.

Content she turned a small notch; deflating the catheter inside. Disconnecting the syringe as she did.
Hastily Fluttershy pulled the front diaper cover over. “There all done, the catheter inside will flush out as you pee. Go ahead sweetie.” Not needing to hear it twice Sweetie Belle grimaced and pushed. Like a dam bursting, the diaper filled rapidly. The filly noisily groaned in relief. ‘Gahhhh’ as the water and urine discharged forth.

Rubbing her haunches together and panting. The liquids poured out for a good half minute. Before simmering out in small intervals. Trickling and stalling; leaving only a swollen, discolored diaper in place.

“Such a naughty filly, just look how much you’ve let out.” Sweetie Belle closed her eyes in shame as Fluttershy pressed on the full nappy. Toying with it before unstrapping it. “Okay, lift your legs up a little.” Ordered the mare as she removed the diaper. It was however unable to contain all the liquid properly; it started dripping. Causing Fluttershy to speedily dash into the bathroom. Departing it and bringing back a wet cloth.

“Hold still” said Fluttershy. Bringing the cloth forth and wiping Sweetie Belle. Cleaning her and helping her stand up from the bed. Wobbling and exhausted the filly went downstairs. Dreamingly she opened the door and exited the house. Her mind seemingly blank…

Epilogue

Two weeks had passed since Fluttershy’s last plaything had left her. Getting up from her bathtub and drying herself. Feeling bored she said to herself aloud “well… time to head back to the spa… for another one…”

Author's Note

Well here we are again. My final chapter, what can I say. It been a helluva ride if anything else hehe.
As most of you can see I’m not an expert in writing. I did this to challenge myself and to prove to others that. No matter how bad you think you are, you should always give it a shot.
I did this story mostly out of frustration as I mentioned before. It’s hard to find in depth pervy stuff like this on FIM. With my short story, well… my hopes are that it will inspire others to write stuff like it. Maybe it will, maybe it won’t. I must confess ‘Celestia’s Relaxing Vacation’ was the story that inspired me to write mine. Sure both stories are different. However the aforementioned story explored a lot of fetishes thoroughly. And that is something I can appreciate. No matter how messed up your story is… there will always be people out there, looking for something just like it. So with my final good bye. I would like to thank everyone that took their time to read my bizarre fanfic lol! Have a good one!!!!
