Misadventures Of Sudden Big Tiddy Syndrome

“Bleh, still nothing,” Twilight said before slamming her face into the desk. All these nights of constant research binges, but to no avail. All she has found are several spells to spice up her sex life and tricks how to make ones bust look bigger, but none that can help cure this syndrome. At this point Twilight might just be better off giving up. But no she has a few ponies riding on her to fix this, so she can’t give up no matter what might she need! To which she is greeted with a loud growl from her stomach, maybe first she better grab a bite to eat before continuing her research.

She decides to head out into town to grab a big lunch, after all so long as she doesn’t have sex with anypony, nopony can catch the syndrome. She gets herself dressed and fixed up her mane and tail to look somewhat normalish, at least by alicorn princess standards. Afterwards she heads out to get a big lunch, to make up for all her time researching.

As she makes her way through Ponyville, she is greeted by the numerous ponies. However after her royal speech debacle many are shooting catcalls at her, to which she now ignores. This whole situation has become rather numb to her in terms of her boobies growing at inconvenient times and has given up on acting modest at this point. It is out of her control, and who knows maybe some lonely stallion would love to beat off after seeing Twilight’s purple jumbo jugs.

She soon finds herself in the market purchasing several things she would need to make the ‘Ultimate alicorn supreme sandwich’ which is based on her level of hunger is just putting everything and anything on the thing.

“Let’s see I got cheese, pickles, peanut butter, jam, daffodils,” she mutters to herself seeing if there is anything else she would need. Unfortunately due to her focusing more on her stomach she hasn’t notice her melons rumbling twice giving the sign that pretty soon, she is gonna have some massive boobers soon. As she walks down to get some cheesy bread the third rumble hits her and her soon EE cup melons begin to grow. Thankfully she notices and with an annoyed sigh rolls up her shirt so it doesn’t get destroyed but in turn draws the attention of everypony within a radius of her. The two twin gals begin to swell and expand as if they were balloons, growing quickly and rapidly to the amazement of everypony. Her boobs soon swell and plump up to a nice HH cup, as she grumbled in annoyance and looks at everypony.

“What never seen mare whose tits grew before!?” Twilight asks the crowd of ponies who just sorta murmur in response.

“Oh my goodness!” a soft voice cries out from the crowd. “Twilight? Is that you!?” the voices cries out once more revealing to be Fluttershy having just got out from her yoga session judging by her yoga pants and tank top and rushes over to help cover up the bare chested, not caring Twilight. “Come on, let’s get you somewhere where you can cover up at least,” Fluttershy says before leading Twilight back to her cottage.

As the two mares get inside the cozy cottage, Fluttershy rushes upstairs to get an old curtain for Twilight to use as a makeshift bra to contain the calamity that is her mammaries. It was an old flowery print with a lime green background and pink flowers scattered throughout it.

“Here this should help keep your bosom well hidden,” Fluttershy declares handing her the old curtain for her to use.. “Tea?” she then asks her alicorn friend.

“Yes, please,” Twilight said using her magic to wrap the curtain into a makeshift tube top. Fluttershy quickly makes the tea before coming back out and setting it down on the coffee table.

“So… how did all this happen?” Fluttershy asks her, clearly unsure if this is the byproduct of some spell gone wrong or something.

“Well it all happened one day,” Twilight begins the long tale of explaining everything that happened. About how she and Spike had sex and how her tits kept growing bigger and bigger each time they randomly expanded. About how she had Rarity help her out but accidently got into a sexual encounter with her, and then about the royal speech going wrong and having sex with Starlight and giving her the syndrome too. “And that is pretty much it,” Twilight finishes with Fluttershy only blankly blinking. I mean she was suspecting something but this is a lot to take in.

“I see, sounds like a real problem,” Fluttershy comments, as a perverse thought enters her head. She had been keeping from her friends her secret thrill of exhibitionism from them, she would often go to Flanksworth and participate as a stripper under a stage name of course. And at times when a few of her fans would recognize her out in public she would give them, private shows in nearby alleys or bathroom stalls. But this news Twilight brought has given a whole new slew of possibilities but first she needs to contract it, without alerting Twilight to her secret nightlife fetish and antics.

“Eh I stopped caring about it,” Twilight said finishing up her tea before getting up to head out back to her castle. Fluttershy panics, so far from what she heard is she had sex with somepony then they got it, so by Celestia’s booty she is gonna get it too.

“Oh, um Twilight I have a small favor to ask,” Fluttershy mentions as she is on the fly thinking up an excuse to keep Twilight around.

“Sure, what’s up?” Twilight asks sitting back down, curious to what is ailing her friend.

“Well...uhh see I got this slight problem that I am embarrassed about,” Fluttershy lies still trying to fully work out her excuse.

“Well it can’t be any worse than your boobs expanding for little to no reason,” Twilight points out.

“You see, I’ve come down with a spot of heat,” Fluttershy says now figuring out her lie.

“Oh, you sure? I don’t smell anything out of the ordinary,” Twilight admits, after all she has had heat a couple of times and usually most ponies can smell it, especially the stallions.

“Oh uh well it’s a more rare type of heat,” Fluttershy makes up, forgetting who she is trying to bullshit here.

“Huh, well there is this place called Flanksworth, I think they offer a service to help mares in heat,” Twilight explains. “Plus I’m good friends with some of the ponies there so they will give you a good price,” Twilight finishes to Fluttershy’s dismay, foiled yet again by Twilight’s logic.

“W-well I don’t want it to be with somepony I don’t know, ya know,” Fluttershy tells her, trying to drop as many hints for Twilight to pick up on.

“I could go ask Big Mac then,” Twilight suggests, clearly letting this fly right over her head.

“No I was thinking more of somepony with a more feminine touch,” Fluttershy suggests.

“Hmmm well I do know a spell that might help,” Twilight said to which Fluttershy just grumbles in an annoyance. This is going to be going on forever so maybe it would be better to just go directly to the point. Fluttershy stands up and approaches her friend before instantly locking lips with her, causing Twilight to go wide eyed before her thinking ‘oooooooh’ in her head. The two pull away both searching for breath. “Okay now I get what you mean,” Twilight tells her, now understanding but now conflicted. If she has sex with Fluttershy she might catch the syndrome, but on the other hoof she is suffering from it, despite Twilight not noticing any of the signs from Fluttershy of being in heat. Twilight ponders on this for a moment before making a decision.

“Ugh alright Fluttershy,” Twilight relents, much to Fluttershy’s delight. She can already see herself now with gigantic sweater stretchers which is making her cunny drool.

“Oh thank you Twilight,” Fluttershy announces. “Come let’s head upstairs,” Fluttershy tells her before leading her up to the bedroom.

The two mares enter the large bedroom, before Fluttershy leads Twilight into the soft large bed, falling on it as the duo lock lips and spend a considerable amount of time swapping spit. Twilight’s horn lights up, casting a spell for her to grow a third leg below the belt. It springs up as blood rushes down to it poking Fluttershy in the stomach, Fluttershy quickly sneaks a hand down to caress the eighteen inch member and it’s duo of baseball sized nuts. The passionate tongue wrestling continues with them both working to undress each other all the while before laying there stark naked and surrounded by the soft silky sheets on the bed.

Fluttershy is the first to begin their romp by engulfing Twilight’s new rod between her soft thick thighs, before rubbing them against the purple pone’s penis. Twilight let’s a moan escape her into Fluttershy’s mouth as she pulls away from the make out session only to latch her lips on Twilight’s mammaries, licking and suckling one of them while working her lower half to pleasure her donger. Twilight can only moan and thrust her pre cum leaking cock between her buttery thighs, seeking more and more pleasure as she smothers Fluttershy between her titflesh, while the pegasus continues to suck her left tit. Fluttershy’s wings extend as she keeps her efforts up, her vagina rubbing against the topside of her shaft, breathing it’s hot pussy breath onto the sensitive rod with her clit giving her a jolt of pleasure each time it passes over a vein. Twilight is left to pant as her cock twitches with a fever and throbs, enjoying the softness of Fluttershy’s buttery thighs and the hotness of her slit’s entrance grinding against her, it is enough to drive anypony mad with pleasure. Twilight’s tongue falls out of her maw while her eyes cross and her sack tightens rapidly, her seed coursing through her cock and bulging her veins as it begins to shoot out into the air like a fountain. Her salty seed rains down on the back of Fluttershy’s legs, butt and getting some in her tail, Fluttershy pulls off Twi’s purple nipple and giggles as she milks every last drop from Twilight’s horsey member.

“Quite a thick load there,” Fluttershy titters, complimenting the messy load Twilight blew while Twilight on the other side pants heavily with sweat forming on her brow. Fluttershy reaches back and scoops up some of the stray cum and brings it to her mouth and gobbling it down. “Mmm tasty, I think I’d like some more of your meat and sauce,” Fluttershy says, stradling Twilight and positioning her hungry cunt over Twilight’s semi erect fuck stick and sinking down onto it and taking her whole in one go. The task was made easy due to Fluttershy having some of her ‘experiences’ with her clients and helping slightly stretch her out, thankfully Twilight doesn’t bother to question it since she is now hilted in Fluttershy’s love canal. Twilight merely throws her head into the soft bed as her dong plunges and explores the moist depths, Fluttershy begins to rise up off the meat stick before slamming back down with a wet squelch. Fluttershy soon smirks at Twilight's enjoyment of her little pony getting ridden, she had seen it on so many of her clients faces and she had picked up a thing or two from them because of it. She begins to add a sort of wiggle to her hips as she comes down with her ass slapping against Twilight’s crotch and her own ass cheeks clapping together on impact, her pace starting out at a slow methodical one taking great rise and falls, building up the desire to copulate between the two, the desire to fuck and breed like mad animals. Fluttershy expertly maneuvers her tail to lightly tickle Twilight’s duo of cum factories, giving a bit of stimulation from her tail hairs tickling the delicate and sensitive sack as they do get jostled each time Fluttershy’s wobbly behind comes crashing down.

Twilight simply lies there allowing her hands to explore the soft curves of Fluttershy’s naked body starting from the pegasi’s soft plush squeezable rump and moving up to her delicious thighs rubbing both sides equally, before giving an emphatic swat eliciting a soft squeal from the shy pony. Twilights handy exploration leads to Fluttershy’s pillowy mounds, out of her group of friends Fluttershy had always been the most busty before all this titty syndrome came along and mucked everything up, but now that Twilight has gained a bit more weight in her chest she doesn’t feel as jealous as she used to be of Shy’s gal pals. Her hands grope and squeeze Flutters twin milk canons as if trying to get them to fire a milky payload but however they are dry as a bone so Twilight settles for imagining if anything. Twilight unknowingly soon begins bucking her hips upwards seeking out more of the moist depths of Fluttershy’s cock warmer with Twi’s purple blunted tip barely kissing her shy friends womb and depositing a fat dollop of pre cum inside it to boot.

Twilight’s hands soon dart for Fluttershy’s hips causing the shy pony to gasp in surprise as Twilight takes control frantically bucking her hips upwards spearing herself into Fluttershy’s slit, letting her juices spill onto the cock inside her and onto the twin orbs holding her tasty seed. Twilight has gone berserk and needs to cum and fast! She wraps her arms around and pulls Fluttershy into her as she pounds Flutters snug cunt, while Fluttershy instinctively smirks knowing that Twilight has giving into her primal instinct due to the light and constant teasing pleasure, has gotten Twilight much like many of the other stallions to fully take their rightful spot as plowing the pegasi’s pussy till she busts a huge nut into her like any true alpha would. Her teeth are gritting together as she continues to claim ownership over Flutters hole, the whole cottage echoing numerous ‘plap plap’ sounds, it is most fortunate none of Fluttershy’s woodland creatures are nearby to hear this intense fuckening. Fluttershy can practically see stars as she gushes and creams Twilight’s rod coating it with her juices and clamping down hard on it to milk it of it’s tasty thick cock cream to sate her hungry cunts need for cum.

“Cumming!” Twilight announces as she sheaths herself once more inside Fluttershy before letting out numerous blasts of thick baby batter inside of Fluttershy’s womb, filling her with the salty reward she had wanted and marking this cunt as part of Twilight’s property with lance after lance filling Fluttershy with a warm feeling as she is pressed down in between the valley of purple melons. Soon she too will have enormous knockers like these for all the stallions to fawn over and all the mares to stare with jealousy, her cunny drools onto the still orgasming purple pony penis inside her, firing off now the last few ropes of cum it has left to spare.

Twilight’s eyes become heavy as she closes them after a few heavy pants only to soon drifts off to get some rest, with Fluttershy pulling off her rod and letting loose a cascade of cum pouring out of her and onto the pour sheets, as Twilight’s mighty spear soon grows soft. Fluttershy soon grabs a large blanket and throws it over the sleeping Twilight, letting her enjoy her post coitus nap. Underneath the sheets Twilight mammaries return to a nice F cup now, not that anypony will notice with them under a blanket.

Fluttershy soon rushes to the shower, and quickly washes off the scent of sex and cum. With her being so excited and waiting for her breasts to begin expanding, she had learned from what Twilight’s stories had suggested that she needs to wait for her chest to start rumbling three times and on the third her boobs would expand. She quickly dives into a fantasy and starts playing with her titties as she enjoys the hot water raining down onto her nude form. A hand sneaks down to play with her clit drawing a jolt of pleasure, as she continues her fantasy of being caught in public with massive knockers for everypony to see and maybe even use.

After a quick shower Fluttershy soon redresses in her sluttiest outfit and began waiting for the first rumble. It only now occurred to Fluttershy that she doesn’t have an exact time or anything to tell her when her breasts will grow except for the rumbles. So Fluttershy just sits on her couch and waits for some sort of rumble, and in the process Fluttershy ends up doing various chores from cleaning up the tea set she had left with Twilight earlier to hanging her laundry outside to dry. Eventually she ran out of chores to do and is left sitting on her sofa, tapping her hoof impatiently for her first rumble. This has her questioning so much now, how does this syndrome work? Is it only at inconvenient times? Did she even contract it? Or did Twilight just make it up? She continues to ponder before she finally feels it, her F cup melons began to rumble to which Fluttershy squeals with excitement before bolting out the door.

She makes her way to the center of Ponyville with a big goofy grin plastered on her face, as she notices the large amount of ponies wandering around. It is at this time the second rumble occurs and Fluttershy can barely contain her joy, she scurries over to a nearby alley and awaits the final rumble before the true fun and fantasy can begin. A few ponies mostly males stop recognizing her from Flanksworth, and approach her.

“Hey are you Vixen Flair?” one asks her, her stage name she came up with because of how much poise she’d have when she stepped out onto the stage and perform.

“Sweet Celestia it is Vixen Flair!? Can I have your autograph?” another asks.

“Yeah but can you suck my dick by chance? I can pay,” a third chimes in as she is soon surrounded by numerous ponies mainly stallions and a few cock bearing mares. And thankfully for Fluttershy that’s when the final rumble hits her and her tits begin to balloon, she pulls them free and let the crowd watched in amazement. It is a good thing she doesn’t wear a bra ever otherwise the poor thing would be in shambles, the small crowd cheers as her bazongas grow soon stopping at a fitting HH cup.

“Anypony want a tittyfuck?” Fluttershy asks before getting on her knees, to which she is met with several ponies fumbling to spring their junk free. The first to get theirs free was this well hung red pony with a neon blue mane, as he approaches with a female companion that looks to be a changeling with an almost as large blue cock between her legs. “Which one of you is first?” Fluttershy asks the duo only to be greeted with the male pushing his dick between her enlarged sweater stretchers. Surprisingly the red pony does have a sizable prick at what Fluttershy assumes to be twenty inches.

“Oh what luck we run into a free titty fuck eh Magma?” the changeling titters to what Fluttershy assumes to be either a friend or a really kinky marefriend.

“Yeah, talk about lucky,” Magma replies as he begins to fuck Fluttershy’s massive melons with a serious fever. His balls slapping into the underside of Fluttershy’s tiddies, causing them to shake slightly each time he hits them.

“Hehe indeed,” the changeling responds stroking her own meat as she watched the overly endowned mare get titfucked by the well hung stallion, licking her lips in envy. The rest of the waiting ponies who got their cocks out follow the mares, forming a queue and stroking their cocks in anticipation with pants and shorts around their legs. Magma grunts after several minutes thrusting up and booping Fluttershy in the nose with his cock before blowing his load straight into her face, getting cum in her nose, eyes, mane and wherever else the load happened to land. He soon pulled out of her valley of cleavage before painting her tits white with cum till his cum factories ran dry and his cock went limp.

“Fuck I needed that,” he says moving to the side to let his female companion have her turn, as she comes up and slaps her meet inbetween the sticky titties. The changeling hums to herself as she works her hips, her neon blue cock peeking out of the valley of cleavage each time and getting a lick from Fluttershy’s tongue each time. Her dick is covered in Magma’s load due to it still being fresh on Fluttershy’s mounds but it only adds to the stimulation as she soon begins firing her own load onto Fluttershy’s boobies. She squeals coating them with changeling cum with a big grin on her face, while Fluttershy now instinctively closes her eyes not to get anymore misfired blasts of seed in them.

“Mmm, that was good,” the changeling says before grabbing her partners hand and walking away.

Hours pass with Fluttershy titfucking many ponies, all showing appreciation by busting their nuts all over the soft titanic sized breasts. And the whole time Fluttershy creams herself, absolutely loving this and not noticing that some pony from above was watching her.
