“So tell me what you think darling,” Rarity asks showing the newly fixed garments to Twilight. “I had to fix it but also reinforced it with stronger materials to fit when your bust decides to expand,” she explains showing off Twilights new wardrobe.

“I see, thanks again Rarity,” Twilight says examining the garments.

“Think nothing of it Twilight, after all that is what friends are for,” Rarity happily replies. “After all you must at least remain decent while dealing with this syndrome,” Rarity adds.

“Yeah I know,” Twilight responds already dealing with one of the after effects of it, her supple D cups are no more as her boobs when not fully inflated are now a nice ripe E cup now. She still has little to no solution of how to fix this, or how she got it for that matter. “I don’t even know how this happened in the first place,” Twilight complains.

“Have you tried retracing what you did before it happened?” Rarity suggests.

“Well lets see, I had just gotten home from after that friendship problem at that erotic club… the club!” Twilight exclaims now filled with determination at her potential lead.

“The club? You mean Flanksworth?” Rarity says slightly confused on what Twilight has in mind.

“I didn’t have it before so Flanksworth must be where I can potentially find a clue,” Twilight says before rushing for the door with excitement. “Thanks Rarity,” is the last thing Twilight says before bolting out the door.

“Wait! You forgot the clothes I made for you!” Rarity shouts out trying to get her attention but to no avail the alicorn princess was long gone and heading to her destination.

After a short run Twilight soon finds herself at Flanksworth. The club she visited for the friendship problem which may be the root cause of this whole shenanigans.

Twilight approaches the entrance only to see the line isn’t what it was the other day, rather more scarce and with a different bouncer, a female one at that. The bouncer was light green in color with a rather masculine looking face which would confuse most ponies if not for her bust, her mane and tail that were light green and light yellow.

“Line is that way,” she says sticking a thumb out and pointing to the back.

“I am aware but I must get in,” Twilight politely says causing the mare to groan in frustration.

“Look I get asked this every time, I don’t have a dick that you can suck to get in and I don’t care how big is whatever you are packing,” she states. “I have a partner who I very much enjoy sex with,” she finishes her explanation. “So if you want to get in, head to the back of the line like every pony else.”

“Well um I wasn’t planning on doing any of that, my name is Twilight Sparkle I was here yesterday and helped out two of the mares that work here,” Twilight explains.

“Oh yeah think Boner Garage mentioned you,” The bouncer points out.

“Yeah, I just would like to see Scorch if that’s possible, I have something really important to ask him,” she mentions with a hint of begging in her voice.

“Eh I guess since you know Scorch and since the line is barely full I can let you go on ahead,” she states unhooking the velvet rope and allowing her to pass into the erotic club.

She enters to the familiar sight of the stage seeing the two mares she helped Velvet Rumpcake and Tiddy Tina, both giving a double strip show with them licking and groping each other while the crowd of patrons go wild. Twilight blushes at the sight especially when they spotted her and give an excited wave to her follow by blowing a kiss to her, to which Twilight puts a pep in her step heading to Scorch’s office.

She gives a knock on the door.

“Come Ngh in!” a voice on the other side shouts. Twilight takes a moment and hesitates remembering last time walking in on some mare being speared by his cock. She mentally prepares herself for what might be on the other side, before grasping the doorknob and twisting it open.

Inside she sees nopony except for Scorch sitting down with an oddly wide grin plastered on his face.

“Oh hey Twilight, wasn’t expecting to see you here again,” He says with a surprised tone in his voice. “I guess you saw Tina and Velvet’s show?” he asks her, causing her to turn crimson again.

“Yes but that isn’t why I am here,” Twilight explains.

“Oh so here for some pleasure then, I won’t tell,” Scorch says in a sultry tone causing Twilight to turn red with embarrassment.

“N-no not that definitely not that!” Twilight stammers out quickly. “It’s about something else, I think something odd happened to me when I came here,” Twilight explains. ‘Ever since I visited here my breasts have grown to propostorious proportions randomly,” she informs him.

“Hmmm that is odd,” Scorch points out. “I have heard about this condition before but never looked into it,” he admits. “But if you ask me I believe you may have caught it from somepony perhaps,” he explains.

“So you believe it’s contagious? That is a possibility, but there isn’t much to support it,” Twilight notes.

“How about you interview most of my mares who were working here,” Scorch suggests.

“Wouldn’t it be faster just to interview the ones I met? Like Velvet and Tina as well as Boner Garage to be safe,” Twilight questions, she isn’t sure how many mares were working.

“Well it’s incase if one pony had it first then gave it to somepony who you ran into as well as customers,” Scorch explains. “Plus I have just the pony for the job,” he mentions, pushing his chair back. Twilight raises an eyebrow before seeing a head pop out under his desk, at least he was more subtle this time around. The figure stepping out from under the desk standing much taller than expected at about almost seven foot to be exact, with an egg shell white coat and a beautiful sleek black mane with a few highlights varying from pink to purple. Her legs looked quite curvy but had a hint of muscle in them which is seen throughout her body finding the perfect balance of the two despite the fact that her legs do look like they can crush a watermelon with little to no effort at all, atop her chest sits two pillowy mounds she can call breasts they look to be about no less than a J cup in size. Her outfit is pure a pure black latex suit with a zipper going down her valley of cleavage that hugs her curves tightly. She gazes down at Twilight causing Twilight to gulp nervously looking at this behemoth of a mare. “Twilight meet Flanksworth’s resident disciplinarian Tanya Titantanks,” Scorch says introducing her.

“It iz pleazure to meet you,” the tall mare says with an odd thick accent.

“Uh the pleasure is mine, I am Twilight Sparkle,” Twilight says giving a polite introduction.

“Da, don’t worry mizz Zparkle I vill promize to find vat you are zeeking, you have mein vord” Tanya says before heading to the door escorting Twilight out of his office.

“Best of luck!” Scorch yells out to them before the door closes.

“Come ve vill start by interviewing all ze girlz from yezterday,” Tanya says before leading her off to the employee’s only section, a part of the area where the entertainers can relax and prepare for their shows or entertaining customers. It is split off into two areas one for the mares and another for the stallions, the two enter the mares area.

“Alright front und center!” Tanya shouts as she enters the back area causing all the girls to stand straight up in a line together, seems this is what Scorch meant by the disciplinarian. “Now lizten, zis here iz Twilight Zparkle ze princezz of friendzhip and zhe haz zome queztionz for uz,” Tanya explains to them. “Und I vant you to treat her like you vould treat me und zhow her the zame amount of rezpect,” Tanya booms.

“Yes Tanya!” they all say in unison, making the tone change from the back area of an erotic club to a military boot camp.

“Twilight zey are all yourz,” Tanya says with Twilight meekly clearing her throat.

“Th-thank you Tanya, I just would like to speak with anypony who was here yesterday,” Twilight asks.

“You heard her all poniez who weren’t working yezterday go get back to vork!” Tanya booms once more, causing a few to quickly scatter and go back to their duties.

“Alright I will be blunt has anypony here had an issue with their breasts growing to large size randomly after thy seemingly rumble three times?” Twilight asks, hoping for some information no matter how small it may be. The room falls silent with the mares looking to each, unsure what to make of it.

“Vell? Zee Princezz azked a queztion vhere is zee anzwer!?” Tanya shouts causing them all to stiffen straight up.

“Well I haven’t had any experiences like that, I was down in the gloryhole section,” One mare pipes up.

“I was stuck with a rich client all day so I didn’t see or experience like that,” another chimes in.

“Only big thing I saw was this mare’s fat cock,” A third notes.

“Okay, how about any clients?” Twilight asks them.

“I didn’t have any female clients only male,” one informs.

“Wouldn’t it be better to ask the male performers?” a second one adds.

“Yeah they get more female clients,” a third one points out.

“Hmm they make a fair point,” Twilight mutters to herself. “Tanya can we go talk to the stallions?”

“Da ve can,” Tanya says. “Alright dizmizzed!” she shouts before escorting Twilight to the stallions performers, the mares soon ease up no longer worried about receiving a scolding by Tanya.

“Alright ztand up ztraight!” Tanya booms again getting the attention of the males, as almost all of them scramble to attention, except for one. “Ve have a princezz here vho vantz to azk zome queztionz!” she shouts before noticing that one stallion isn’t at attention and is busy seemingly getting changed. “Oi you zere vat iz your name!?” she shouts clearly angry at the stallion getting changed.

“Uhm it’s Magma, my shift just ended so I’m getting ready to leave,” he explains.

“Zat iz no excuze I vill deal vith you perzonally,” Tanya booms. “But before that princezz Twilight haz a few vordz,” she says glaring at Magma.

“Thank you Tanya, I am here to ask if any of you had an odd experience with a mare whose tits suddenly grew large randomly,” Twilight asks, causing a few mutterings.

“Nope sorry,” one chimes in.

“I only have male clients and none of them grew tits, they just pounded me in the butt,” another mentions.

“Well I guess this was a dead end, thank you all for your cooperation,” Twilight says with a sigh.

“You are all dizmizzed except for you!” Tanya announces before grabbing Magma.

“Wait me? Wha- hey put me down!” Magma proclaims, as he is lifted up by Tanya who escorts Twilight out.

“I am zorry I failed you in your zearch and worzt yet, zomepony acted out of line,” Tanya says with a hint of sorrow in her voice.

“I wasn’t out of line! I was just trying to leave!” Magma protests trying to squirm his way free, but cannot escape her grip.

“It’s okay,” Twilight politely says after all she didn’t do anything wrong and Magma was just trying to leave.

“Nein I must be reprimanded for mein miztake pleaze follow me,” Tanya says before escorting Twilight to one of the backroom’s marked ‘Peep Show’.

As they make their way into the room it is dominated by sofas and loveseats and a huge bed at the end of the room, to which Tanya throws Magma onto.

“Um Tanya, just what are you planning?” Twilight asks, unsure of her thought process.

“Zimple I vill dizcipline zis ztallion and pay for my failure by having you watch. Zis iz how you zay two birdz with one ztone,” Tanya mentions as she begins to pull Magma’s pants down exposing his lower half and in particular his semi erect penis.

“Wait I have nothing to do with this my shift is ov- mph!” Magma tries to protest but is stopped by Tanya sitting on his face.

“Now is not zee time to be talking, ve have guezt to entertain.” Tanya states. “Pleaze Twilight, get comfortable and watch az I zhow him domination,” Tanya claims before unzipping her suit allowing her boobs to fall free of the latex prison and wrap around his dong. Twilight gulps before slowly sitting and watching the show, least she knows why this area is called the Peep Show. “Mozt marez barely know how to zuck a cock properly, I vill tame zis cock vith mein lipz,” Tanya states before wrapping her lips around his pecker and in the blink of an eye engulfing half of his length in one go, she is quite talented. She begins bobbing up in down eliciting muffled moans from him, with his cock growing rock hard and standing at a proud twenty inches when it isn’t down Tanya’s throat. “Gulp, gulk, schluck,” are a few of the sounds Tanya makes as she continues to down his dick while her hand sneaks it’s way to fondle and squeeze his hefty sack of nuts. Twilight has no other choice but to sit and watch unable to unglue her eyes from the sit or leave the room, granted the sight was making her snatch damp with excitement, she fights to suppress the urge to masturbate however taking practically all her willpower to stop herself from indulging to desire. Tanya eventually incorporates her tits into the mix having them wrapped tightly around the base of her shaft as she swallows more of his inches, spit shining his meat each time taking him deeper in deeper into her throat.

“Mpphf! Mmmm gonna blow!” Magma shouts out still muffled by Tanya’s asscheeks, his cock thrashing and throbbing in her throat before exploding unleashing a torrent of hot cum down her gullet filling her with warmth. Not even struggling she easily gulps down his seed as if it weren’t even a challenge, she swallows every last drop even stroking his base to coax any straggling amount he hadn’t fired off yet.

“Mmmm zis is healthy male, produce plenty of cum,” Tanya notes pulling her soft lips off his member and raising her ass off his face allowing him to breath once more. “But ve are far from done da,” she says before fully removing her latex suit and stroking his softening member to prevent him from going limp on her. “Now zat you have zeen mien cock zucking zkills I vill tame your beast with mien bottom,” Tanya warns him before climbing atop him pressing her pucker against his cock tip before slowly engulfing his meat stick. Magma moans as Tanya hits his base with her ass wobbling with the smack of her bouncing off his lap over and over. Twilight turns red watching Tanya’s heavy ass raise and fall slamming into Magma’s red orbs each time, Magma on the other hand is holding onto her jiggly rump as she continues to ride his bitch breaker like an unbroken stallion. While holding on for dear life Magma makes the effort to knead her wobbly ass, showing it’s softness and jiggle to Twilight who bites her lower lip feeling a slight heat of lust come over her as she continues to fight it with all her might she can muster. However that in it of itself was a battle with the sight she is watching as well as the scent of sex and the musk of a male are enough to drive an average mare wild with lust, but Twilight soldiered through it not giving in to the temptation of pleasure, no matter how much she wanted it.

“Unnnnngh!” Magma grunted out his cock being held captive in Tanya’s booty hole, his cock throbbing in time with his heartbeat. Tanya soon wraps her bountiful bosom around his head, fully engulfing it minus his horn which sticks out.

“Zuch a naughty beast of a cock you have, but don’t vorry Tanya vill tame it,” Tanya reassures him rubbing his head that rests between her titties, still riding his ‘beast of a cock’ with great vigor. Magma soon felt more blood leaving his head and being rushed to his dick barely able to breath while surrounded by mounds of soft titflesh. His balls soon start to tighten rapidly giving off a tell tale sign he is close to his long awaited orgasm, and not a moment sooner despite being an Amazonian, Magma can barely keep up with Tanya’s heavy rear bouncing off his lap.

“Mmmmphf! I’m cumming!” Magma shouts still muffled by Tanya’s mammaries, as his cock begins unloading it’s gooey contents in her asshole,fully lubing it up with plenty of stick seed.

“Da, zat iz good keep cumming,” Tanya whispers stroking the back of his head, while Magma keeps pumping his thick baby batter into her. “Princezz Twilight I hope you enjoyed ze zhow, but could you zee yourzelf out, I muzt make zure he iz fully milked,” Tanya says looking over her shoulder at the reddened Twilight, who is watching some of the spooge leak out of Tanya’s butt and backwashing onto Magma’s nuts. Twilight nods and slowly gets up and heads for the door, and leaves the room and the club heading home.

As soon as Twilight enters the castle a panicked looking Starlight runs up to her.

“Twilight! Where in Equestria have you been!?” She yells panting.

“N-nowhere!” Twilight respond in the same volume as Starlight her redness shining through.

“Well I don’t know where you have been but did you forget about the ponies your suppose to address?” Starlight informs her, only for the information to hit her smack in the head. Of course tons of ponies came from far and wide to hear her speech, well hopefully she has enough time to get ready and prepare for it.

“R-right, what time am I supposed to go on again?” Twilight nervously asks.

“You are supposed to be on in fifteen minutes!” Starlight informs her, to which Twilight scrambles to her room to get dressed with Starlight following behind.
‘This is the worst possible thing to happen, how can this get any worse?’ She wonders before feeling a rumble in her chest. ‘Oh no’ she thinks not now, as she throws on her Princess gown, this can’t be happening as she worries about this more and more.

“Ten minutes Twilight!” Starlight says knocking on her door, taking a deep breath Twilight composes herself for what is to come. She can do this, she just needs to give her speech and get out of the public eye as fast as she can.

“Okay, ready,” Twilight says as her and Starlight make there way to the balcony to address the ponies.

After climbing the steps that lead to the balcony Twilight steps out to see the sea of ponies awaiting her.

“Greetings my fellow ponies!” Twilight yells addressing the ponies causing them to roar happily. “I am greatly pleased that you all have gathered, I wish to speak to you about the current state Equestria is in,” Twilight begins remembering her speech. “I understand some of you may not be as open about us becoming more friendly with our neighbors and other denizens outside of Equestria, I as the Princess of Friendship believe doing this will help us become more aware and learn more about their cultures!” Twilight continues before feeling a rumble in her chest, this isn’t good that’s the second rumble. “A-and we should welcome them as one of us, as we have much to er uh learn from them and that they can uh,” Twilight says stumbling panicking internally and constantly repeating her points. Starlight senses this and goes to ask Twilight what’s wrong before she feels it, the third rumble. Her tits soon start to balloon with Starlight backing up slowly, the crowd confused not being able to see clearly while Twilight panics, grabbing her melons trying to stop it, but it was unstoppable. The fabric of her dress gives out her boobs flopping out onto the railing of the balcony, the crowd gasps in awe before roaring in cheers.

“Twilight! Twilight! Twilight!” they cheer happy to see her massive melons.

“Please uh listen I can-... oh fuck it,” Twilight says giving in utterly frustrated, resting her head in one hand while tapping the railling with another, her tiddies stopping at a large double K cup, causing the crowd to cheer while some flashes of cameras go off.

“Uhm, that isn’t contagious, is it?” Starlight asks Twilight only to get a lingering glare back. “Just trying to be safe,” Starlight says feeling odd, they did look so appealing. Before long Twilight let’s a sigh and takes her leave.

“Thank you all, and I dunno enjoy my massive tits,” Twilight says annoyed before taking her leave as the crowd continues to chant her name.

“Ugh why did this have to happen!” Twilight complains before sitting down on a nearby couch.

“It isn’t so bad,” Starlight mentions trying to cheer her up, staring longingly at Twilight’s tits.

“Trust me it’s gonna be all over the papers, and worst I am so fucking annoyed and horny at the same time! Why does this keep happening!” Twilight vents before getting back up and storming off to her room with Starlight following her.

“Wait horny?” Starlight asks as Twilight flops on her bed.

“I was at an erotic club trying to get information about this instead I ended up watching a show that’s why I was so late,” Twilight explains planting her face into a pillow.

“I see,” Starlight says before activating her horn using her magic on herself, as if being made by clay her snatch is replaced temporarily with a sixteen inch horse dick and two low hanging balls. “So how was the show?” Starlight asks before rolling Twilight over and latching her lips onto Twilight’s tit.

“S-Starlight!” Twilight shouts in confusion before moaning feeling Starlight’s tongue flick against her nipple. Starlight uses her magic once more, this time on Twilight boobies making them swell slightly before they then start leaking milk.

“You are fine with this yes?” Starlight asks, for Twilight to respond with a nod before Starlight uses her magic for a final time removing her and Twi’s clothing exposing each of their bodies to each other. Starlight goes back onto Twilight’s now lactating tit, with her drinking down heaping gulps of it, all the while aligning her new dong pressing against Twi’s purple pussy before spearing her way into her.

“Ahhhhhhhh!” Twilight howls in pleasure, at the initial penetration she immediately cums clamping down on the invader squirting out her own fem lube onto the bed covers. After a moment allowing Twilight to adjust to her size before working her hips while taking big gulps of Twi’s milk, her hips working on her own. “Ha ha, is this what you and Trixie have been doing in your private magic lessons?” Twilight asks inbetween pants, her cunt working to milk Starlight’s member, with Starlight nodding her balls echoing filling the room with the sounds of “Fwap fwap fwap.”

“Maybe I have maybe I haven’t,” Starlight teases popping off her nipple before latching onto the other one before rolling her hips as she continues to pound the purple vagina her pink pony penis is balls deep in nearly hitting Twilight’s womb her blunted tip nearly knocking on the entrance.

“Naughty mare,” Twilight says grabbing and pulling Starlight’s head into her teat, stroking the back of her head lovingly as she nurses from her as if she was a babe. Twilight sighed happily she is finally getting stuffed quite well, still quite turned on from the show Tanya had put on for her, she wraps her legs around Starlight in an attempt to draw her deeper inside of her cunt she was feverishly fucking.

“Shit I am gonna cum soon!” Starlight announces pulling off Twilight’s nipple having had her fill and doubling her pace slamming in harder and harder her balls flying back and forth, Twilight gasped at the sudden change in pace her large melons wobbling and shaking with each thrust, Starlight desperately trying to reach her peak and discharge deep in Twilight’s love canal. “Fuck, fuck I’m cumming! Oh sweet Celestia I’m cumming!” Starlight announces before putting her head between the mega mounds of melons and sheathing herself fully in Twilight cock milker and shooting off lance after lance of thick cum deep inside painting it from purple to white in an instant. Twilight howls feeling the hot liquid love spread throughout her giving her an odd feeling of warm fullness, watching Starlight spill every last drop of seed deep inside her, she really did need this. Starlight soon pulls out and flops backwards her cock slowly shrinking back in before revealing her slit once more, seems the spell lasted until she came. On another note Starlight seems to be support a bit of a paunch in her belly, could it be from all the milk she drank perhaps? Twilight wonders as more cum escapes from her and staining the linens. Ah well that can be figured out later for now sleep beckons as Twilight closes her eyes and dozes off.

Author's Note

In regards to Tanya's speech, she has an accent hence why there are Z's and V's instead of S's and W's it's simply how she speaks, felt like I had to write this for any confusion
