Chapter 1: How did all this happen?

“Where is that book?” Twilight ponders searching up and down her royal library for this book with no luck thus far, scanning every shelf for it but with little to no success. “I know I saw it around here,” she mutters still searching while pulling out books before placing them on a table quite annoyed as she cannot find what she is seeking. She soon stomps the ground in frustration and pulls on the collar of her wool sweater.

“No luck huh?” Spike asks Twilight entering into the library.

“No i’ve looked everywhere. I thought we alphabetize these last week?” she says looking at him.

“I thought you told me to categorize them based on genre,” Spike responds not pleased with being potentially blamed for her not being able to find what she is seeking.

“Well it doesn’t matter least I know why I haven’t been able to find it since I thought we alphabetize them instead I keep finding ‘Anon’s Bizarre adventure’ and ‘One Kick Stallion instead of the book I am looking for,” she mentions starting to now change her search to a different shelf.

“We have One Kick Stallion?” Spike says before grabbing the manga book and going off to read it. Twilight quickly finds the shelf she didn’t search and spots the big red book on the top shelf, she gets a ladder to help her reach it as she climbs it struggling to reach it.

“Ngh come on,” she says only getting her fingertips to touch it before pulling it out. “There woah!” she exclaims accidently losing her balance and falling on her plush bottom and ruffling her short skirt. “Ow…” she groans slowly rising back to her hooves at least she got the book she had been looking for. Picking it up and going to join Spike who was deep into reading his own preference, as she begins studying her own book titled ‘Mythical Illnesses and Curses’ grabbing a sheet of paper on the table and taking notes with her magic looking into some of the oddest occurrences of illnesses and some curses have happened in the history of Equestria. “Hm Anudeispedia a supposed disease only found in stallions where they must see nude mares or they will supposedly turn red and puke blood and die, it has been reported this turned out to be a false illness by doctors researching and discovering it was used to trick mares into undressing for horny stallions,” Twilight mutters jotting it down as notes before going on to continue reading about false illnesses, and taking notes for her research. “Hmmm this looks promising the gae a symptom that includes stallions having intercourse with other stallions who are originally who believed they were attracted to mares but couldn’t exactly rise to the occasion in bed but found they could with stallions,” Twilight continues to mutter slightly annoying Spike having to hear her recite the book. “Let’s see Ligma was an illness believed to take a popular pony’s life but it later turned out to be just a made up rumor,” she continues which annoys Spike to the point of closing his manga book and and go read his book elsewhere with Twilight unaware he even left. “A lot of these are just bogus none of these seem real at all,” Twilight complains realizing this book is rather just recounting false illnesses and things that seemed like curse but were easily explained in the end. “Uggggh and here I thought this would be an interesting subject,” she complains before turning the page. “What’s this one, Sudden Big Tiddie Syndrome, a mare in San Franciscolt discovered one day her breasts grew to an abnormal size before returning to original size, this wasn’t investigate further as she was married and personally her husband loved her and would have sex with her everytime they grew to the large size,” she reads aloud before closing the book. “Welp this was a waste of time,” she claims balling her notes up into a ball before sighing as she heads out of the library and back to her room.

She soon returns to her room and flops onto her bed.

“And here I thought I was onto something with these mythical illnesses,” she whines before burying her head into her pillow letting out a deep angry sigh. “I wanted to discover something interesting to show princess Celestia that I can fix aside from friendships but nope instead I just find a bunch of dead ends!” she shouts quite annoyed.

“Hey Twilight! The map is reacting for you!” a voice shouts knocking on the door.

“Huh?” Twilight responds before opening it with her magic. It was Starlight as she gains Twilight's attention.

“The map it’s responding there seems to be a friendship problem,” Starlight exclaims as the two race to the map.

Upon arriving with Twilight panting Starlight points to the location on the map.

“Seems like there is a friendship problem here in Ponyville,” Starlight informs her walking over to the map seeing Twilight’s cutie mark floating over Ponyville.

“Here in Ponyville? I find it hard to believe a friendship problem could be here,” Twilight mentions looking at the map.

“The map doesn’t lie,” Starlight retorts.

“Well that’s true,” Twilight says. “I guess I should go find whoever is having a problem,” Twilight says before departing to find out who exactly is having the problem.

After about an hour Twilight made her way around Ponyville searching for whomever is having a friendship problem before bumping into a familiar face.

“Oh Twilight you simply must watch where you are going,” A marshmallow colored mare responds after the two unkowingly had a small collision with each other.

“Sorry Rarity I am in a hurry somepony is having a friendship problem here in Ponyville,” Twilight informs her.

“I see well I believe I can point you in the right direction for that,” Rarity responds.

“Really? Who?” Twilight questions surprised at the convenience of this task.

“Over at this adult club called Flanksworth I saw two ponies having a very heated exchange,” Rarity mentions before giving a small wave. “Well good luck I must head back to the Boutique and get to work on my Spring fashion line,” Rarity says before strutting her way back to her boutique, with Twilight heading over to Flanksworth.

She soon approaches the large building with the giant neon sign reading ‘Flanksworth’ approaching to see a long line of eager patrons wanting to get into the club. Twilight views the line with slight concern she can’t exactly wait that long now can she? She makes her way over to the bouncer drawing his attention.

“Uh, excuse me,” she asks before he snorts.

“Back of the lines that way,” he grunts sticking his thumb out pointing to the line.

“Well that’s the thing I need to sorta skip the line,” she says, laughing nervously.

“What reason would that be for?” he snarls back quite annoyed, considering some patrons do try to skip the line from time to time.

“I am the Princess of friendship and I believe there's a friendship problem going on inside,” Twilight explains figuring that being honest may work out in her favour.

“Oh you mean Tina and Velvet? Those two have been at each others throats lately,” the bouncer responds, “How do I know you are the real Princess Twilight exactly?” the bouncer questions eying her as if she is suspicious. Twilight rolls her eyes and sighs stretching her wings out while activating her horn to prove she is an alicorn princess. “Hmmm guess that checks out,” he responds not quite sure what he expected her to do to prove she was who she said she was but that was satisfactory. “Head to the bar and ask for the manager Skorch,” he mentions unattaching the velvet rope for her to enter, causing a bit of grumbling from the line.

“Oh come on! I’ve been waiting for an hour!” one complains.

“Why does she get to cut the line!? I offered to suck his dick! What makes her so special!?” another whines, which Twilight takes as her cue to hurry on inside and avoid any unnecessary drama or attention.

Inside Flanksworth, Twilight sees first hand why this club is so popular. It isn’t just a strip club or a trendy dance club, it seems to be something simillar to a sex club! A large stage for the ‘merchandise’ to dance and entertain the customers while they buy drinks from the bar, and back rooms or booths for them to get a bit frisky with the girls.Twilight feels herself turning from purple to crimson in moments as she quickly power walks to the bar before getting the cute bartenders attention.

“Uh h-hi I am looking for t-the manager Skorch,” she asks dying to get out of here and back home.

“Sure thing cutie that way and first door on your right past the bathrooms,” the bartender tells her giving a small wink while pointing in the direction with Twilight nodding and wandering to where they said.

Twilight takes a deep sigh before knocking on the door reading in large letters ‘Manager’s Office’.

“It’s open come on in!” a voice calls from beyond the door with Twilight doing as instructed.

She soon would come to regret it as it swings wide open and reveals a yellow orangish alicorn stallion with a burgundy mane balls deep in some pegasi mare’s snatch.

“Hello there, I’m ungh shit your tight, Skorch the manager here at Flanksworth,” He calmly says not stopping fucking the mare while carrying out this conversation.

“G-good day, I am Princess Twilight Sparkle I had recently heard that there is a friendship related problem here,” she nervously mentions.

“Oh that explains why you’re here about Velvet Rumpcake and Tiddie Tina,” Skorch says figuring out the purpose of why the princess of friendship is here. “They have had a falling out since an incident recently,” he continues spanking the mares jiggly rump.

“What kind of falling out?” she asks trying to pretend like he isn’t having sex with someone in front of her. He lets out a grunt before ceasing his movement collapsing on top of the mare as her wings flap happily and he moans before slowly getting up and letting out a sigh of relief.

“Basically from what i know is a client who is a regular of Tina’s recently wanted to spice things up with Velvet instead so Tina thinks Velvet is stealing her clientele and that’s where we are at,” Skorch explains pulling out of the mare and sitting back in his chair.

“Okay that is a rather odd reason to ruin a friendship,” Twilight notes.

“Yeah it sucks since they haven’t been able to work together, kinda kills the possibility for threesomes,” Skorch points out causing Twilight to blush.

“R-right maybe if I can speak to them, I can help work them through this,” Twilight suggests.

“Eh sure why not, Boner Garage go get Velvet Rumpcake and Tiddie Tina for me,” he asks the mare he finished fucking.

“Sure thing,” she says walking out with cum dripping from her snatch. After some time two mares one a dark red color with a white mane and a huge butt that jiggles each time she takes a step, and the other a light green with an electric blue mane and tits about twice the size of her head soon enter both purposely looking the other way from each other with mass amounts of disdain on their faces.

“Girls I brought you two here at the request of Princess Twilight,” Skorch explains.

“Ugh I don’t see the problem here aside from this big butted ho stealing my customers” Tiddie Tina spits.

“Please least this butt gets customers unlike those saggy tits of yours,” Velvet scoffs back causing Tina to slap her plush rump before the two start physically fighting.

“Wait stop, stop!” Twilight cries getting the two to stop mid fight. “Now listen you two were friends are you really gonna let this client tear you apart?” Twilight asks them.

“Well… I don’t want it to,” Tina admits letting go of Velvet’s hair.

“Yeah I don’t want to either, it was a slow day when I took him for a private show cause he wanted to try anal for the first time,” Velvet replies looking down.

“Wait why didn’t you tell me? You know I don’t do anal, so that’s why he requested you,” Tina exclaims.

“Friends?” Velvet asks.

“Friends!” Tina says pulling Velvet into a hug.

“Well… that went faster than normal,” Twilight admits.

“Well either way glad to have them back as friends again,” Skorch admits before reaching into his drawer and pulling out what seems to be a piece of paper and handing it to Twilight.

“What’s this?” she asks before looking down and reading it. ‘Free private show and sex session coupon!’ she soon turns to crimson again.

“Consider it a thank you for helping out,” he tells her with a friendly smile.

“U-um yeah okay thank you I have to um go now so bye,” Twilight says before taking off out of the club and back to her castle.

She soon gets back before walking to the library.

“Hey Twilight how’d the friendship problem go?” Starlight says passing her by with a wave.

“Fine! It went totally fine! Nothing out of the ordinary!” Twilight exclaims still a bit shaken up about the world she had stepped into.

“Are you sure?” Starlight asks

“Yeah of course why wouldn’t I be!?” She questions Starlight making her feel uncomfortable.

“Okay what got up your butt?” Starlight questions.

“Nothing! Nothing at all! No phalluses or toys nothing!” Twilight screams reminded of everything she saw.

“Right I’m gonna go hang out with Trixie now,” Starlight says before awkwardly walking away from Twilight. Twilight sighs heading into the library deciding maybe a book will be the best way to calm down.

Twilight uses her magic to grab a book off the shelf and sit down before sighing and diving into the literary wonders of the book. Turning the pages as she finds herself lost between the pages and time seeming to be endless for her to read and should she finish she simply grabs another one with her magic and repeats the cycle. While already on her fifth book something felt off, a rumbling sensation she could feel resonating in her body, she dismissed it as a sign she may be getting hungry and would grab a bite to eat after she finishes the book. Once again she feels it but it isn’t coming from her stomach it’s coming from her chest? She looks down feeling them rumble then suddenly feels as if they were inflating! They soon begin straining against her wool sweater.

“What in Equestria is going on!?” she claims aloud, she has always been a double D cup so what is happening to them? As they soon burst through the sweater still growing rapidly from an E cup to F cup than a G cup! She panics not knowing what to do as her tits now rest on the table still growing until they stop at a double I cup. How did this happen! How is this even possible? These thoughts rush in her head trying to apply logic to this situation. She tries to stand up but is met with a difficulty since she isn’t used to having such a weight on her back from her enlarged rack.

“You know I don’t get why Twilight says manga books rot your brain they really- Sweet Celestia!” Spike cries out at the sight of Twilight beached on the table with her massive set of titties. His face suddenly becomes flushed with a blush after all he had turned eighteen and he always has been a connoisseur of great melons namely Rarity’s but these are even bigger than hers. His dragonic dick soon bulges against his pants, turned on and surprised at the same time. As for Twilight she doesn’t know what to think her face equally as red as Spike’s, due to the embarrassment and suddenness of this whole situation but what’s more is why is she so turned on by this? She bites her lip before looking to Spike.

“Um Spike, do you think you can help me out? I’m kinda beached here,” Twilight asks him, after all this is a thing friends do right? Help other friends who are stuck due to their boobs growing too large, casual stuff. Spike gulps before walking over and lifting them taking a sharp gasp at there softness and soon becoming distracted as he gropes them over and over a clawed finger brushing over her purple nipple eliciting a moan from her. Instinctively he brushes by it again soon reaching to pinch it. “Ah S-spike! What are you doing!?” Twilight exclaims her panties gushing with juices as he toys with her tits. Moving his mouth to her nipple before he suckles her teat, as if he were still a baby before reaching down and stroking his dragonic member through his pants. Twilight tries to protest but the words that escape her are nothing but moans each time his tongue flicks across her areola, filling her with pleasure. Were her nipples always this sensitive or is this another side effect of whatever has happened to her mammaries? Or is it because of that club and how everypony there was having a good time and indulging in each other’s bodies for pleasure, maybe that is why this feels so good? He soon pops off her nipple before looking at her eyes deeply.

“T-Twilight do you mind if I…” he mutters stumbling on each and every word, his heart beating ten times as fast as normal at what he is asking her for with sweat pouring down from his head. She picks up on it quickly and figures out by looking past her enormous melons and down at his pants seeing the outline of his donger, she nods panting as if to say it is okay. He swallows heavily moving his hands to his pants before slowly lowering them, exposing his erect thirteen inch dragonic member and baseball sized nuts. Twilight gulps seeing for the first time Spike’s penis in its glory, she had caught him fapping once or twice but he usually hid it from her. He soon climbs on the table lifting her boobs before aligning his lap underneath her melons before dropping them with his cock parting her bountiful bosom with his tip peeking out from her cleavage, she looks down before seeing his member be more exposed he quickly works his hips fucking her massive tiddies. Twilight feels the quaking of his crotch slamming upwards on the underside of her breasts causing them to jiggle along with a quiet slap slap sound of his balls hitting her soft flesh making it wobble each time. Twilight cranes her neck downward before wrapping her lips around his pointed tip, making Spike moan with pleasure at the warm wetness of her maw, and sneaking a hand down between her legs as she uses a few digits to enter her drooling cunny. Spike moans and groans each time he seeks out more of her mouth. Twilight soon scoops her large tits in her hand before lifting them up and down matching his own speed with his thrusts, feeling him twitch between her breasts while his member throbs in time with his heartbeat. “Ngh….” is all he lets out his dragon spooge hitting her tongue making her eyes go wide with surprise at the hot salty treat the dragon is shooting into her mouth, she lets him fall out of her mouth which results in her getting a face full of his load before he shoots the remainder of it all over her oversized jugs coating them with plenty of dragon cum each, before she ends up swallowing the hot treat he left her.

“Ah You should have warned me you were gonna cum,” she complains with a pant.

“S-sorry it felt so good,” he apologizes, while Twilight is soon able to lift the chest weights she is sporting off the table.

“I-I'll scold you about that later but first you gotta help me with a problem,” she says standing up and pointing behind her, her cunt has soaked her panties with it’s juices begging for attention. Spike nods as he moves off the table and goes behind her. She bends over giving him approval and access as he starts hiking her skirt up and lowering the soaked undergarment exposing her purple plush rump and winking pussy. He gives her butt a squeeze before aligning his dick with her entrance feeling the moistness already trickle onto his tip as well as the heat her snatch is breathing out onto his donger. Taking a big breath of air he slowly advances forward spearheading his way into the purple pussy before him as it parts and surrounds itself around him, hugging him tightly. Twilight bites her lower lip, unsure of this newfound sensation inside her but it’s divine, he takes but a moment to get his bearings inside her before he begins moving his hips pulling out before slowly and methodically sliding back inside her.

“O-oh Rarity you are so tight,” Spike remarks clearly lost in a fantasy in his head thinking he is fucking Rarity instead of Twilight which Twilight lets him indulge for now. He enjoys his soft and slow pace making a little impact when he bottoms out against her plush bottom, each time coping a feel of Twi’s butt as he keeps his steady pace up not wanting to ruin it being still tender after already cumming once hence his approach. Twilight however having not yet reached an orgasm of any form bucks backwards against his pelvis causing her rump to bounce ever so slightly in time with his thrust each time echoing with a loud ‘plap’. “T-Twilight, I am still sore!” Spike complains snapping out of his fantasy and feeling her force herself back against his crotch in her attempt to take command and speed up the pace. She ignores his compliant and shakes her ass in defiance as she forces her ass back down upon him bouncing off him once more only harder. Each bounce causing an echo throughout the empty library. The force of her bounces making her massive boobers shake each time her mind trapped in lust eager to get off, her pussy clamps down on the draconic penis tightly threatening to crush it at any moment.

“Cumming!” the two cry out in unison with Twilight gushing around Spike’s member and Spike shooting another thick load of creamy baby batter into Twilight’s penile prison. Twilight sighs happily her eyes crossing while she rides a wave of pure pleasure and Spike holding on for what feels like dear life, with a mix of feminine juices and spunk dripping onto the floor below. After some time the two come down from their respective orgasms both panting to catch their breath and suddenly Twilight’s massive tiddies soon begin to shrink as if deflating and return back to their respective size albeit still covered in Spike’s cum.

“Fuck that was an interesting spell you tried out Twilight,” Spike remarks pulling his now soft cock out of her.

“It wasn’t a spell I don’t know how they grew to that size,” Twilight respond wondering how that happened. “Tch whatever it was just ruined my favorite sweater,” she complains about the large ripped hole in the sweater.

“Just go see Rarity she can fix it probably,” Spike suggests while putting his pants on.

“Yeah good idea, and speaking of… you called me Rarity while you were doing me,” Twilight teases recalling which makes Spike turn fully red in embarrassment and having been caught red handed. “You were fantasizing about fucking Rarity weren’t you?” Twilight presses before Spike quickly bolts for the door too embarrassed to be seen now that he has been found out. Leaving Twilight all alone still confused as to what happened to her.

Chapter 2: A Quick Fix

In the castle’s dining area Starlight hums happily setting the table with the plates, silverware and last but not least the food. Using her magic to set plates of pancakes, a bowl of various fruits, beverages and plenty of syrup and butter. She takes her seat now that the table is set waiting for everyone else to arrive.

“Ughhhhhhh,” Twilight groans wandering in looking like an absolute mess, her mane and tail both are frizzy and unkempt, her eyes have bags underneath them.

“Good morning Twilight, sleep well?” Starlight asks before realizing that was a stupid question to ask.

“Does it look like I slept well?” Twilight snaps back giving a glare at Starlight. “I was up all night researching odd illnesses,” Twilight informs Starlight before using her magic to pour her a cup of juice and grab some pancakes and syrup.

“Odd illnesses? I thought you gave up on that?” Starlight questions recalling seeing the book and crumpled up notes she left from yesterday.

“Certain circumstances made me change my mind,” Twilight mentions, deciding that clearly she contracted big tiddy syndrome like in the book. But how? The symptoms are the same yes but how did the first reported mare get it? Is it permanent? What causes it? She has to find out, if anything to prevent it from happening again.

“Morning Starlight,” Spike announces entering the dining room and sitting down before blushing at Twilight. “M-morning Twilight,” he nervously says before reaching for pancakes.

“Morning,” Twilight says giving a small wave before shovelling forkfuls of pancakes down her gob. Starlight looks at the two sensing there is a small amount of tension in the room. She looks back between the two before slowly piecing it together.

“Oh sweet Celestia what did you two do?” Starlight proclaims looking at the two seeing Spike starting to sweat bullets and Twilight seemingly not caring about it.

“Well...uhhh,” Spike stammers out.

“We had sex,” Twilight flatly says before taking a bite out of a banana.

“You did WHAT!?” Starlight shouts.

“T-Twilight!” Spike stammers out embarrassingly.

“What? It’s not like anything has to change, it was the heat of the moment,” Twilight explains causing the room to fall silent.

“Well I guess that’s true… I just hope Rarity wouldn’t be jealous,” Spike points out.

“Spike… you haven’t even asked her out yet,” Twilight mentions.

“I-I’m working on it,” Spike it admits, he hasn’t worked it out how to ask such a beauty like Rarity out. After all she deserves only the best and Spike does want to be the best of the best,

“You will now when the time is right Spike and she will fall head over hoof for you,” Starlight encourages drawing a happy smile out of Spike. The trio proceed to enjoy the rest of breakfast scarfing down plenty.

“Ahhhhhh I’m stuffed!” Spike proclaims patting his stomach with a big grin plastered on his face.

“I will get to cleaning up,” Starlight says, using her magic to grab all the dirty dishes and fly them into the kitchen.

Elsewhere in the castle a loud banging noise is heard at the entrance to the castle.

“I’ll get it,” Twilight said getting up and heading towards it using her magic to grab a brush to fix her mane and tail.

She swings the door open only to see the familiar face of the postmare, Derpy Hooves.

“Package for Princess Twilight Sparkle,” Derpy says reaching into her mailbag and pulling out a clipboard and the package in question. “Sign here please,” the cross-eyed mare asks handing the clipboard while Twilight quickly writes her name down. Twilight hands it back and Derpy hands her the package before placing the clipboard back in her bag. “Have a nice day,” Derpy says before flying off.

Twilight heads back inside holding the package wondering what could it be?

“Whatcha got there?” Spike asks as he walks by curious to see who was at the door.

“Just some mail, seems I got a package,” Twilight notes.

“Oh from who?” Spike asks, curiously Twilight looks down at the package label before seeing a seal and her face turning red once she sees the name ‘Flanksworth’ on the side of the package along with the sender's name being Titty Tina and Velvet Rumpcake. “So who’s it from?” Spike pipes up curious to know who sent Twilight the package.

“O-oh you know nopony special I think this is one of Pinkie’s gag packages, you know,” she tries to play off while internally screaming for her dear life.

“Ah those are always fun be careful with it, I don't want to clean up the confetti this time,” Spike says before wandering off. Twilight breathes a sigh of relief as she makes her way to her room to open the package.

Upon reaching her room she slams the door shut. She moves to her bed sitting on the edge before opening the package, revealing a giant purple dildo, a folded up note, what seems to be an instruction manual, a harness like item and several vials containing a white liquid. Twilight feels herself turn fully red as she picks up the giant horsecock dildo complete with it’s own set of balls too, she blushes further flicking the blunt headed tip seeing it lean before flopping around slightly. She gulps grabbing the note and unfolding it before reading it.

‘Dear Twilight, We know that Scorch gave you that coupon as a reward, but we wanted to pay you back personally. So we went down and bought the best quality dildo, it’s a whopping nineteen inches and three inches thick! And it even has this cool feature of actually cumming like a real cock but the fake cum is like super expensive, so we asked one of the studs here at Flanksworth if he could donate some of his seed and he happily obliged so you can have some fun with it. It also comes with a harness to attach it to that turns it into a strap on if you have any marefriends who are into kinky stuff like that. We even named it! It’s called Twilly’s Dee, get it? Cause Dee is like the letter d and it’s slang for a dick oh well Tina thought it would be funny just so you know who’s writing the letter. Oh and don’t worry about the quality we made sure to test it for the Princess of Friendship and it’s the bes! We also disinfected it too so don’t worry about it being not clean. Be sure to stop by to visit us just to chat or for some pleasure. Sincerely Tiddy Tina and Velvet Rumpcake. P.S careful with the cum, the stud we got it from apparently has accidentally knocked up a few mares here and his seed is super potent so don’t use too much without proper preparations on hand.’

Twilight sighs putting her head in her hands. While she appreciates the thought she can’t believe they did something like this, she lifts her head up. She reaches into the package before reading the manual.

‘Thank you and congratulations on your purchase of the Mistress’s Bitch Tamer 8000 dildo!’ the first page reads. ‘This is our latest model from Naughty Wyvern productions the Bitch Tamer 8000 comes with various features such as; refillable balls, stimulation levels that result in an auto cumming feature, a pleasure stimulator and strap on to dildo capabilities. So whether you yourself are looking to break in your partner or be tamed yourself. Naughty Wyvern is not responsible for any sexual injuries you may suffer or stuckage in any orifices the product was put in or any impregnations you may experience. Please fap responsibly.’

Twilight blinks a few times not quite sure how to feel about that as she puts the manual back in the package. She then lets out a before going into her drawer and getting her ruined sweater. If anypony will know what to do, maybe it will be Rarity and if not least her sweater will be fixed. She changes out of her outfit for something more casual a simple black shirt that hide her push up bra, some yoga pants and to top it of her limited edition Princess Celestia zip up hoodie, she then closes the package and puts her torn wool sweater along with the package in a bag before heading out.

She makes her way through Ponyville being greeted by all the residents of the town. She smiles happily to them even waving to more than a few who greet her. So far nothing can ruin her day… that is until she feels an odd familiar feeling, her chest begins to rumble slightly.

“No…” she says to herself, trying to as if tell her tits to not pull what she thinks they will do to her again. Especially outside with tons of ponies around every corner, she internally begins to panic but doesn’t feel the second rumble. She doubles her pace trying to get to Rarity’s boutique as quick as possible while still being polite to any passerby wishing her a good day. After cramming a research session she learned a bit more from the mare who first was reported of having it, the main reason she knew when it would happen was the rumbling. It would happen three times before eventually ballooning after the third rumble, she did also note that whenever they expanded she got extremely horny whenever they did expand however specialists chalked it up as ‘horny embarrassment’ or perhaps that she was exhabitionist. At least with this slight knowledge Twilight knows what to look out for but her main concern is the other effect, the mare who first had it was a B cup and had since in her normal condition had gone up to a J cup when not inflated. This bothered her as her breast have maintained their current D cup size this could happen to her as well, she must find a cure or some sort of prevention method aside from hiding and waiting till her tits shrink back down to their regular size.

She soon makes it about halfway to the boutique, thinking she will eventually be able to make it there before the second warning rumble would ever occur. Or so she thought…

“No no no! We can’t put that in the gift basket!” a voice cries out in complaint. It was Bon Bon and Lyra and they seem to be arguing about something, until they turn their attention to Twilight.

“Oh good day Twilight think you can help us out?” Lyra asks her.

“Well what exactly are you two doing?” Twilight asks the duo, she knows she doesn’t have much time but her instinct to help other ponies is currently overriding her worries.

“Were supposed to make a gift basket for Cherilee’s anniversary of becoming a teacher,” Bon Bon explains.

“But we can’t quite decide what to put in it,” Lyra tells her. “I thought we could put like flowers and fruit and stuff,” she continues.

“And I thought we could fill it with supplies she would need for school, you know pencils, erasers, rulers,” Bon Bon explains.

“Well both are good ideas but why not mix the two together,” Twilight suggests before it kicks in. her chest starts rumbling. She immediately starts panicking internally once again, this is her body warning her for the second time she doesn’t have much time before her boobs expand.

“Yeah your right!” Lyra exclaims.

“Can you help us pick the stuff out for the basket? We want it to be perfect,” Bon Bon explains, which causes Twilight to bite her lower lip. On one hoof she does have to get to Rarity’s before the syndrome kicks in but on the other this is her duty to help other ponies.

“I suppose I could,” Twilight decides figuring if she can quickly assist them she can rush over to the boutique and hideout there till they shrink back down, surely Rarity won’t mind.

“Great let’s go!” Lyra cheers as they all go along shopping for items to put in the basket, they quickly fill it up with various supplies along with flowers and fruits as well as some various mane care appliances and face creams.

“Alright that should be plenty, thanks again Twilight,” Bon Bon says before her and Lyra give a wave goodbye. Twilight breathes a sigh of relief now all she has to do is get to Rarity’s before the third rumble in her chest occurs. Unfortunately for her as if on cue the moment she turns around her chest rumbles once more, it was too late and there was nothing she can do. The moment her chest stops rumbling it begins to inflate growing larger and larger just like last time, the fabric in her shirt stretching to the maximum capacity when her tits reach EE cup, her bra unfortunatly gives way snapping off as it can no longer hold her chest pillows up any longer. Her shirt follows suit ripping thankfully the only part not being torn is her hoodie mainly due to the fact she didn’t zip it up it just moves out of the way for her enlarged boobies to take full view unhindered by any form of fabric, they stop growing after hitting a J cup, much larger than last time, being exposed to the breeze of the day causes her nipples to grow stiff due to being freed from their prison. Okay it happened but she is only fifteen minutes away from Rarity’s and surely nopony would be able to spot her now I mean her melons are bigger but that shouldn’t draw attention to her, right?

“Holy Celestia! Look at the big tiddy purple pony! Her tits are so big they’re hanging out!” a male pony shouts. Twilight stands completely still holding her breath.

‘Please be talking about somepony else.’ she thinks to herself. ‘Please sweet Celestia let there be another pony who is purple and him not talking about me please!’ she internally screams.

“Woah those melons are like the size of my head!” another comments.

“Wait, I think that’s Princess Twilight!” one exclaims, and just like that Twilight slowly wishes she could dive into a hole and hide. But strangely enough it feels… good? Why is she enjoying this?

“Sweet Celestia that is Princess Twilight!? When did her boobs get so huge!?” a pony questions. Now slowly being crowded Twilight basically gives up, with an annoyed sigh she slowly makes her way to Rarity’s with her swollen mammaries, a task proven quite difficult due to the extra weight and the crowd of stallions staring in awe. The more they stare with their slackening jaws the more aroused she gets, could she be developing an exhibitionist streak herself? Or has she always been like this.

“If your all gonna stare can somepony get me a drink!?” she complains out loud as a few ponies scurry off to get her a beverage. After a minute or two, one returns with a beverage handing it to her. “Thank you,” she says taking it and taking a large sip through the straw tasting the beverage, it was fruit juice she then looks at the gawkers. Shrugging she nestles the drink in between her tits with the straw facing her as she takes another sip and starts casually walking drawing the attention of everypony as she walks down the street. A few of the onlookers trip as they stop to stare at her naked breasts some even with their marefriends immediately get kicked in the crotch or end up in an argument for staring. This makes her feel even more better for some reason, her snatch freely spilling juices staining her panties.

After some time and a whole cup of fruit juice later she finally arrives at the boutique opening the door which catches Rarity’s attention.

“Welcome to Carousel- Great Mooning Mare in the Moon!” Rarity exclaims, her soft white marshmallow cheeks turning crimson at seeing Twilight and her new found weight enter.

“Sup,” Twilight responds before going to throw her cup out in the trash.

“Twilight? Wh-what happened to you? Your chest is so massive!” Rarity stammers not believing what she is witnessing, she always had a bigger rack then Twilight with her bountiful F cup bosom. But Twilight is sporting makes her feel outclassed boobie wise.

“Long story,” Twilight says. “I got something called ‘Sudden Big Tiddy Syndrome’ it causes my breasts to expand randomly, can’t tell if it’s genetic or something like that,” she begins to explain. “Yesterday my boobs expanded and destroyed my favorite wool sweater and while I was on my way here it happened again destroying my bra and my shirt I thought you could fix my sweater and shirt and maybe tailor me some clothes that can support these puppies,” Twilight finishes explaining purposely leaving out the whole bit with Spike, while Rarity stands there trying to process all this.

“So… is it permanent?” Rarity asks.

“Nope it goes away after awhile,” Twilight responds.

“Well I guess I can do this for you as your friend. Come come,” Rarity tells her as they head into the back.

Once the two get in the back of the boutique, Twilight puts her package down on a nearby table.

“Alright let’s see where did I put that,” Rarity says to herself looking in some drawers before finding what she needs. “Ah ha!” she proclaims before turning to Twilight with some measuring tape. She approaches before wrapping the tape around Twilight trying to get an accurate chest measurement.

“Hehe, hey watch it Rarity that tickles!” Twilight tells her trying her best not to laugh.

“Stay still darling I need these measurements,” Rarity scolds her trying her best to measure Twilight’s overly large bust. Constantly struggling as Twilight’s laughter causes her boobs to jiggle making it harder to get an accurate measurement. She grunts in frustration accidentally groping her time and time again, a mix of lust and jealousy. Why was she feeling this way anyway? She did have one of the biggest busts in the group but now she has to compete with Twilight newfound knockers. She continues to measure her chest but keeps fondling her over and over.

“Um… Rarity?” Twilight awkwardly asks, figuring out she must have finally measured her chest by now. So why did she keep measuring her and squeezing her chest. “Have you got the measurements you need?” she asks her.

“Yes darling I got all the measurements I need,” Rarity casually says still squeezing her melons before flicking her thumb against her nipples.

“Then shouldn’t you stop?” Twilight asks being slightly turned on by this turn of events.

“No,” Rarity flatly states. “You are turned on by this though aren’t you?” Rarity says with a smug grin.

“M-maybe…” Twilight meekly responds. She was getting aroused by all this, and after the other ponies staring at her this is just the icing on the cake.

“I knew it!” Rarity states soon tossing away the measuring tape and openly fondling Twilight’s chest and licking her nipples. “You are loving this aren’t you?” Rarity asks only to reach down between Twilight’s legs using two of her digits to rub against Twilight’s sopping wet panties. “Such a slut! You are soaking wet down here!” Rarity exclaims soon pinching and twisting Twilight’s nipples, causing her to scream in pain and pleasure. Twilight wasn’t sure what has gotten over Rarity but has remembered the rumors she heard about Rarity being a closet dominatrix. Either way nothing Twilight can do but enjoy what’s happening. “Hmm, let's see how much damage these fat cow tits of your did,” Rarity mentions using her magic to bring the bag over pulling out the package and the sweater. “Oh what have we here?” she asks in before opening it and pulling out Twily’s Dee. “Oh my Twilight you saucy minx, a mistress’s bitch tamer 8000? You slutty mare you planned this didn’t you?” she asks her grinning before flicking her tongue across a nipple making Twilight holler in pleasure. “No need to say anything you already answered that question, and I am feeling in a rather randy mood,” Rarity admits in a husky voice before releasing her breasts to go over and put on the harness, leaving Twilight panting wanting more. She easily slips into the harness and makes sure everything is secure, she pulls out the vial of cum provided by the mysterious stud and puts it in the dildo before easily snapping it onto the strap on portion. “Perfect, now before I get to business lube it up why don’t you?” she says before pushing Twilight down to her knees and face to face with the huge purple silicone dong. Rarity grabs Twilight’s horn before slapping Twilight with the dildo. “Go on I haven’t got all day,” Rarity mentions giving another cock slap. Taking the hint Twilight opens her gob and starts taking the first few inches of the fake donger. In the strap on a custom pleasure stimulator that gave shockwaves of pleasure to Rarity’s little button making it feel as if she was actually getting head from Twilight, such advancements in pony pleasure. Rarity soon seeks more and begins to force Twilight to take more by pulling her cock forward moving her to take more then half and unhinge her jaw slightly.

“Glup! Slurrp! Mphf!” Twilight lets out various sounds before hitting the base her chin bumping into the silicone balls, with Rarity guiding her Twilight finds herself stuffing down the plastic purple phallus, opening her throat to welcome it as deep as her throat will allow it.

“Hmm that should suffice,” Rarity notes before pulling out, allowing Twilight to catch her breath with her panting like a dog in heat. “Now that it is properly lubed up under my work station, on all fours ass up,” Rarity commands leaving Twilight to obey as he crawls under the desk and lifts her dainty rear up as high as she can go, practically shoving her own face into her own pillowy breasts. Rarity pulls down Twilight’s yoga pants just enough to expose her soaking wet panties and moving them out of the way revealing the purple pussy the alicorn princess was hiding, she then aligns the strap on with it’s target before cocking her hips back and giving a hardy thrust forward parting Twilight like a curtain.

“Ooooooooooooh!” Twilight cries out in pleasure gushing and tightening around the plastic member. Rarity begins a steady pace slamming home each time causing the titflesh that is beaching Twilight to wobble with each thrust. Before too long Rarity uses her magic to fetch the ruined sweater and to remove the fragments of the ruined shirt from Twilight’s body and gets to work all the while still working her hips not missing a beat. Twilight can only moan loudly while Rarity happily hums getting lost in her work and almost forgetting she is fucking Twilight with a strap on, working diligently to repair one of the garments. The room fills with multiple plap plap sounds, as Rarity still feeling the stimulation but rather not focusing as much on it with her hips working on auto pilot constantly pounding Twilight’s purple pussy, but still working her hands to sow the sweater back together and stitch it up very nicely and making sure it is just as fashionable as it once was.

“C-cumming!” Twilight announces her snatch clamping down desperately trying to milk the fake penis as if it were a real one seeking it’s seed, spraying fem juices all over the floor.

“Magnifique I am done!” Rarity announces finishing fixing the sweater before her own orgasm is reached in celebration triggering the phallus to begin discharging the load provided from the vial deep inside Twilight, painting her cunt white and packing her womb. “Oh my that is quite an aftershock,” Rarity notes finding her balance by leaning against the table while Twilight sighs happily. “Well darling I fixed and reinforced your sweater, so you keep lying back while I fix your shirt and get a whole wardrobe ready,” Rarity says and as if cued Twilight’s tits slowly begin shrinking before Rarity although she can’t see due to Twilight being under a table. “Anyway time for round two,” Rarity says looks like Twilight is gonna be stuck here for awhile, not that she doesn’t mind after all.

Chapter 3: Bad Timing

“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

Chapter 4: Whoops

A newspaper is thrown and hits into the front door of the castle, before the door is opened by Twilight yawning and stretching adjusting her eyes to the sunlight before bending down and grabbing the paper, and retreating into the castle.

Twilight soon opens up to read the headline.

‘Princess Twilight’s speech great success! Everypony loving her idea of friendship using big breasts! Approval rating through the roof!’

Well seems her speech has made front page and not in the way she wanted. She rolls her eyes quite annoyed by this turn of events. ‘Friendship by using big breasts?’ that has to be the dumbest thing they wrote but then again there was nothing else she could do. For all they know that was planned despite it being an accident, hopefully this doesn’t reach Princess Celestia and the ponies of Canterlot.

“Ugh why me,” Twilight complains, before throwing the newspaper aside. How can she show her face after this? All of Ponyville saw her expanded knockers, and she still hasn’t found a way to reverse or stop the effects of it. Instead she has been caught in an oddly arousing situations with her friends and has soon lead to them doing the deed. Speaking of which, where has Spike been all this time? She hasn’t seen him since breakfast yesterday which is odd considering the many duties he has here at the castle, so where has he been? She didn’t see him at the Royal addressing, and Starlight never mentioned seeing him or having him help look for her, so where could he have gone? Twilight gets up from her self mopping and goes off to look for him.

“Spike! Where are you!?” she shouts as she searches in the kitchen, the map room and library but to no avail. She soon feels her tits rumble giving a warning to her of what comes next. Well at least she isn’t out in public and considering that both Starlight and Spike have seen her with her jumbo jugs that it would be no problem now.

She soon makes her way to his room since that is the only place she hasn’t looked. She gives a knock on the door.

“Spike you in there!?” she calls out to no answer, she crouches down to look through the keyhole. Sadly she sees nothing before eventually feeling the second rumble in her chest, she sighs before removing her top as to not have it ruined like many of her other clothes. Besides no one is around so decency can take a back seat, however she still hasn’t found Spike, where could he be? Surely he left some form of clue as to where he went. Using her magic she easily unlocks the door before entering Spike’s room.

Walking in she notices the room is surprisingly clean, seems like he has taken the advice of that book she gave him. ‘How to get the mare of your dreams by keeping your room clean’ was one of the best presents she gave him considering how messy he use to leave his room before reading that. She quickly looks through his room trying to find some sort of clue as to where he has gone, perhaps that will be an idea of what to get him a journal solely for situations like this. However, she does find a big box under his bed only containing what looked to be a purple cylinder shaped object with the name ‘Pocket Ponut’ written on it and at one of the ends was a simulated mold of a white vagina, that has been used very well and considering the odd dried up off white stains used recently. Twilight slowly puts it back in the box not sure what to think about finding it but making a mental note to wash her hands after. When did he get it? And how did Twilight not know about it? Surely this wayward dragon is quite sneaky it seems.

However before long she feels her third rumble sighing as she knows what happens now with her melons ballooning slowly to a much larger size, good thing she took her shirt off because it seems to be going much faster without any form of restriction. They soon reach a double K cup, before Twilight flops onto the bed with her boobflesh wobbling as she lands. This is the first time she is alone for once without anypony walking in on her for once and some lewd shinanagaians ensuing. It does feel kinda good to be alone with nopony to bother her, maybe just this once she can enjoy the experience of it. She roams her hand across her expanded mounds, giving them light squeezes as her other hand follows suit reaching and teasing her areola before grabbing and twisting her tender nipple which sends a shock of pleasure that runs down her spine. A cute moan escaped her lips as her other hand gropes her right tit bringing it towards her maw to suckle on her purple teat, covering it with her own saliva before pulling and pinching her nipple in her other hand. This was nice it’s just her and no pony else, her snatch getting wetter by the second she continues to tease and play with her headlights completely left out and ignored from the fun. She can get used to these titanic jugs, after all Rarity always loved to show off her own cups despite never admitting to it and all the stares it would attract from the stallions followed by some glares from jealous mares. She lets out a happy sigh thinking back to yesterday when ponies were staring at her, mouths open in shock and desire, bulges and tents forming in their pants, minds slowly running with lewd fantasies of what they would do with her jumbo jugs. Dear Celestia just thinking about this was driving Twilight wild her pussy is practically gushing with her juices as she is thinking about this, and she hasn’t even touched herself yet but there is a great fire down there, that is yearning to be put out.

A loud banging noise coming from the closet causes Twilight to snap out from her enjoyment and immediately sitting up and looking at the closet.

“Spike?” she says before getting up and approaching it, before it bursts open and a figure rushes and knocks her over onto the bed.

“What were you doing in my bed!?” a slightly feminine voice questions, Twilight looks up trying to get a good look at the figure who rushed her. It looks like Spike with more softer features and a set of J cup sized knockers.

“Spike is that you?” Twilight asks unsure if this is the real deal or some doppelganger.

“Of course it is!” Spike yells back. “I’ve been grown these things and worst yet look what I am missing!” she shouts before getting up and pulling her pants down, to reveal a naked slit. “My dick is gone!” she cries.

“What!? How did this happen? And why were you hiding in the closet?” Twilight questions utterly confused as to what’s happened.

“Okay… here’s what happened, it all started after breakfast…” Spike begins.

Yesterday in Spike’s room after breakfast…

“Boy does Starlight make good pancakes!” Spike cheers, before lying down on his bed staring at the ceiling pondering on the events of last night. He doesn’t know what came over him, just seeing Twilight and those juicy melons made him go bananas, and while he did imagine he was doing it with Rarity the whole time, he did feel kinda embarrassed afterwards. But Twilight said it was a one time slip up and it won’t hurt their friendship, hell it might even strengthen it which is a huge weight off his chest. He lets out a sigh of relief before feeling a familiar sensation, seems thinking about yesterday and Rarity got him all hot and bothered. Luckily he has just the thing to fix that.

Spike leans over the edge of his bed searching for his box of ‘fun’ toys, in particular his favorite. The ‘Pocket Ponut!’ a very expensive toy he had to save up for months to afford. But it was all worth it for the pleasure and enjoyment he has gotten out of this thing.

He stands up to take off his pants kicking them aside for now before flopping back onto the bed. Positioning his toy right above his dragonic member, with it kissing the entrance of the fake vag. He lowers it slowly allowing his cock to spear right through it causing it to part around him engulfing his donger. He lets out a moan of pleasure as he continues his slow and even pace until his balls feel the plastic mold against them. He soon lifts it back up until only the tip remains inside before bringing it back down, finding an even pace to his masturbation aid. He barely even notices the rumbling in his chest that has happened twice as he is too distracted by rutting his favorite toy, slickening it up with his dragon pre cum, speeding up slightly eager to reach his peak. He hits his limit before shooting off his load into the toy flooding it with his dragon spooge as if he was trying to impregnate it, a goofy grin spreading across his face totally in bliss until he feels an odd rumble in his chest. He ignores it not thinking it is anything but slowly he feels as if his chest is…expanding? This drags him back down from his orgasm to notice what is going on, he scrambles to remove his shirt before panicking, he is growing boobs!

“What in Equestria!” he exclaims not knowing what to think as his newfound melons keep growing going past F cup, did he get the same thing as Twilight? How is it affecting him, wouldn’t this only affect mares? Whatever the case may be he finds his new found mammaries have stopped growing giving him a pair of double I cup breasts. “Well this is odd,” Spike thinks to himself unsure of what to think, he moves a hand to grope his own boob. It does feel like a real breast, but what caused it? He felt his chest rumble and they started to grow to a ridiculous size, originally Spike thought it was an odd spell Twilight misused on herself, but maybe it’s something else? Could it be a curse? Hopefully this isn’t permanent. Oddly enough Spike’s dick is still rock hard despite having just dumped a fat load of dragon baby batter into the fake pussy, could it be he is strangely turned on by his sudden growth of his own knockers? Well whatever the case may be he still does have his toy out, so might as well rub another one out. He soon picks up where he left off a task aided by the spooge he already let out, dripping down his cock and pooling on his sack. The tightness hasn’t faded for him as his dick throbs inside the plastic mold, while a clawed hand fondles his left tit drawing out a moan from him as he continues to use his mastabtory aid. He closes his eyes and lets his imagination run wild as he fantasizes about his first time with Rarity, of her descending down on his aching member and taking him whole in her supple cunt. With his hands reaching to feel her bountiful bosom, while thrusting upwards eliciting a moan from the beautiful mare, his hefty nuts pounding into her pussy lips each time he fully sheaths himself in her, her soft rump gracefully bouncing off his lap each time. Both panting heavily taking pleasure in each others sweaty bodies the smell of lust filling the room, along with the sounds of sex, Spike reaches to grab a firm hold on her boobs feeling a pressure rising in his shaft. Coming back down to Equestria and out of his fantasy Spike removes the toy before stroking himself to his release shooting thick wads of cum all over his belly and on his new found tiddies, covering them with his dragonic seed. His tongue falls out of his mouth as his eyelids grow heavy, the grip on the toy all but fading away as sleep takes him.

Hours later…

Spike slowly wakes to the sound of somepony banging at his door.

“Spike!? You in there!?” the voice calls out, it was Starlight and judging by the tone in her voice something was wrong. “I can’t find Twilight and her public addressing is supposed to start in an hour!” Starlight says with a shaking worry in her voice, she waits for a response from Spike but hears nothing as she sighs in annoyance before taking off to look elsewhere.

“Oh snap I forgot about tha-” Spike starts to say before cutting himself off. What’s wrong with his voice it sounds more feminine then it should be, he looks down at his chest before realizing he still has boobs albeit slightly smaller now at about what could be considered C cups. He slowly gets out of bed grumbling about this idiotic spell before looking in the mirror and turning his face into one of horror. “Ahhhhhhhhhhh!” Spike screams now noticing his body is more feminine in more ways than one. He now had more definitive curves to his body, most of his masculine features are gone and toned down to more softer features his scales were less rugged and more sleek. But worst of all his crotch no longer bared his pride and joy, now gone and replaced with a pink slit. “This is the worst day of my life, ever,” Spike sobs, now realizing he has gone from a dragon to a dragoness. How did this happen!? Why did it happen!? What can he do!? He continues to ponder as he paces back and forth, is it permanent or will it wear off? Either way he cannot be seen like this by anypony until it does wear off, hopefully.

“And that’s what happened, and ever since my boobs keep growing randomly!” Spike tells Twilight, shaking her as he still doesn’t know what is the cause of it.

“It’s okay Spike I can explain,” she says back to him. “It’s called Sudden Big Tiddy Syndrome, I originally thought it only affected one random mare but seeing as what happened to you it’s clearly contagious,” Twilight points out.

“Yeah I figured as much,” a voice says from the hallway, with both of them turning their attention to see who it is. It was Starlight and judging by her destroyed shirt and J cup jugs and angry expression. “I thought you said this wasn’t contagious!” Starlight complains.

“I didn’t think it was!” Twilight fires back.

“Well what are we supposed to do!?” Starlight questions.

“I don’t know, I am sorry all this happened,” Twilight apologizes realizing this is mainly her fault after all, she did bring this in somehow.

“Ugh why you didn’t tell anypony else is beyond me, we all could have looked into this instead of each of both of us fucking your brains out!” Starlight complains causing Twilight to turn crimson.

“Wait you two?” Spike points out.

“Yes we did, her tits expanded during her speech and then got horny afterwards,” Starlight explains before having a realization. “Wait, do you get off on this stuff Twilight?” Starlight questions.

“Uh well…” Twilight stammers out not sure how to answer.

“She was masturbating in my bed a few minutes ago,” Spike rats out Twilight.

“That settles it then, you Twilight Sparkle are a little slut aren’t you?” Starlight says with a devious grin plastered on her face, while walking into the room. “A horny little alicorn who gets off on her tits expanding to the point she would let anypony with a dick into her marehood,” Starlight teases, lifting Twilight’s head up with just a finger. “And since you gave us these big honkers it’s only fair we teach you a lesson for acting like an airheaded bimbo,” Starlight says lighting her horn up causing both her and Spike to grow dicks and balls respectively. The only difference seems to be while Starlight has grown a pink horse dick, Spike seems to have regained his lost cock. “Now be a good girl and suck our fat cocks,” Starlight commands pointing at her dong.

“Um well do I hav- Mppphf!” Twilight says getting cut off by Starlight’s pink horse member spearing past her lips, forcing Twilight to start sucking her off. Spike approaches in slapping one of Twilight’s cheeks with her dragonic dick eagerly awaiting her turn into Twi’s maw.

“Yeah suck it up like a good slut!” Starlight teases before grabbing the back of Twilight’s head and forcing more meat into her mouth then she can handle.

“Gluck! Glup, schluck!” are the only sounds Twilight can use to protest but she couldn’t help but feel a tad bit turned on by this, after her time with Rarity she did enjoy being utterly dominated by a mare with an intimidating aura to her, and Starlight has filled that to a tee. Twilight however does do her best to orally please Starlight, thrashing her tongue along the underside of the veiny intruder.

“Don’t hog her mouth! I don’t want to be slapping her with my dick all day,” Spike whines almost drawing the ire of Starlight.she pulls out allowing Twilight to get a few breaths of air into her lungs.

“Alright then have at her I am gonna pound that pretty purple princess’s pussy then,” Starlight says with a smirk on her face, using her magic to lift Twilight onto all fours on the bed and lowering her panties. Juices already flowing out of her snatch. “Sweet Celestia, you are this wet? You secretly are enjoying this aren’t you?” Starlight teases jerking her cock before lining up with Twilight’s love canal.

“Alright then, open up Twilight!” Spike says before ramming her dragon dick into Twi’s maw. Meanwhile Starlight begins spanking Twilight’s purple derriere leaving her handprint visible while her free hand strokes her dong keeping her erect.

“Guess it’s time to plow this princess’s cunt then,” Starlight teases before nonchalantly shoving her meat spear past Twilight’s purple velvet curtains and exploring her moisten depths. Twilight squeals a bit at the sudden penetration only to slightly gag on the slick dragon penis in her mouth, feeling her body being rocked forward when Starlight bottoms out inside her. “Oh I think our little slutty princess likes it rough,” Starlight notes feeling Twilight constrict around her.

“Oh does she?” Spike asks Starlight. “If so I might get a bit more rougher and make her take me deeper,” Spike claims as he thrusts forward, entering her throat. Depositting plentiful amounts of pre cum to lube his way and give Twilight a salty snack while she’s at it. Soon the two get quite rough with Spike pulling Twilight’s mane as she sucks her off and Starlight ramming her way into Twi’s womb and constantly spanking her purple jiggly bum until it turns from purple to red.

“Fuck yeah I could keep this dick if I get to fuck this slutty snatch everyday!” Starlight cheers speeding up to further ravage the purple cunt even more. Her balls hitting against the purple clit sending a tingle through out Twilight’s body further fueling the fire of her pleasure of being spitroasted by a horny dominating mare and a lusty dragoness. The duo take full advantage of Twi’s body drilling themselves as deep as they can go, constantly causing Twilight to rock back and forth onto the others rod taking an extra inch and a half of them. The room filled with the sounds of constant ‘plap plap fwaps’ each time Starlight’s sack slams into Twi’s entrance or when Spike’s nuts bangs into Twi’s chin. The scent of sweet and wild lust filled their nostrils with Twilight’s brain going blank between squeezing Starlight’s pink cock and sucking down Spike’s pipe. She could get use to this, just getting rutted day in and day out by these two, isn’t that what friends do right? Help each other out? Either way it feels good, maybe this is one of the positives of her whole syndrome, or maybe Starlight is right and she has just been a closet slut turned into a closet bimbo now due to her syndrome? Who knows might as well enjoy the fucking. She soon clamps down on Starlight’s invader as she sprays the pink nut sack with her feminine juices, and staining Spike’s bed.

“Oh cumming already?” Starlight teases, before grabbing and pulling Twilight’s tail to tell her to back her ass up a bit..

“Awwww damn that’s gonna take forever to come out,” Spike whines noticing Twilight’s juices are getting on the bed spread.

“You are getting sucked off, and are worried about your sheets getting dirty?” Starlight questions giving a hardy thrust followed by a spank to Twilight.

“Hey gotta have priorities,” Spike responds before fully sheathing herself in Twilight’s maw. “Fuck I’m gonna cum!” she proclaims as her cock throbs and twitches rapidly causing pressure to build up along his shaft. She pulls out slightly going from Twilight’s throat to her mouth leaving just the tip inside while her hand latches onto her rod and furiously strokes it to draw out her load. The first blast of dragon seed hit’s Twilight’s tongue giving her a nice taste, the second one hits the back of her throat causing her gag reflex to go off. Spike soon pulls out at the last second to finish all over Twilight’s face and massive mammaries, marking her as much as possible.

“Mmm Yeah you love dragon cum don’t you?” Starlight teases, watching Spike unload all over her. Using Twilight as a canvas, and Spike’s cock as a paint brush and her cum as paint she fully coats her and her tits before going back into her throat to shoot off the last remains. Doing so causes Twilight to gag slightly as her head is held down by Spike’s hands to the base of her crotch. Twilight’s eyes go wide as she coughs and gags forced to swallow Spike’s load, she ends up coughing some of it up onto the base of her crotch and some fall onto Twi’s jumbo jugs. “Swallow that dragons cum!” Starlight commands desperately humping Twilight, her peak just in sight.

“Fuuuck that was a good blow job,” Spike proclaims pulling out one last time, feeling her cock growing soft. She begins watching Starlight feverishly plow Twilight’s pussy in, her face determined to cum with her gritting her teeth. Twilight having been on the receiving end of this can only endure it as her poor abused snatch is further ravaged by the pink intruder, her tits and butt wobbling around each time Starlight fully sheathes herself inside.

“Ngh aghhhhhhhhh!” Starlight lets out as if it was some sort of roar to announce her orgasm as cum begins shooting out of her cock and slowly filling and spreading throughout Twilight’s vagina and even entering her womb. Starlight collapses onto Twilight’s back forcing Twi to support Starlight’s upper body and big boobers, while being filled with plenty of nut butter to the point it spills out and drips down onto the sheets.

“My sheets…” Spike whines quietly while she watches. Twilight sighs happily enjoying the warmth she is feeling while Starlight finishes dumping the last of her load inside her.

After some time Starlight passes out with her magic wearing off causing her cock to disappear while Spike’s mysteriously stays. And speaking of mysterious things their breasts still remain the same size not shrinking back down. It is then when a loud banging is heard from the castle doors.

“I’ll go get it,” Twilight said getting up and walking to the front, buck naked wearing nothing but cum and with mare spooge leaking out of her cunt.

She soon get to the door and swings it open only to be greeted by the sight of Rarity with no top on sporting a pair of what she can estimate as L cup size melons.

“Twilight I believe we have something to talk about,” Rarity remarks, with a glare in her eye.
