Misadventures Of Sudden Big Tiddy Syndrome

A week had passed since the incident with Twilight and her tiddies bursting forth from her shirt and growing to ridiculous proportions. But thankfully she has thought of certain contingencies to this. She had gathered her friends who are affected by this syndrome in order to prevent it from spreading.

“Alright everypony, now that we are all here, let us discuss what we know about this so far,” Twilight said as she looks to her friends. She was still a bit guilty since they only got the syndrome from her. “So we know that three rumbles and on the third the expansion happens,” Twilight begins jotting all this down on a chalkboard. “And anypony I have had… relations with,” Twilight says.

“You mean sex right?” Starlight chimes in.

“Ahaha yeah that,” Twilight says growing redder at the comment. “But back on topic we know how it was contracted but we don’t know where and why?” Twilight explains but suddenly all their racks start rumbling and the entire groups tits start expanding destroying their shirts either ruining all the buttons as they burst off or just ripping open as the fabric couldn’t contain the boobflesh. “And that is mighty convenient,” Twilight says annoyingly.

“Quite so,” Rarity says. “But darling how are we going to manage with this?” Rarity asks.

“Yeah and I need a certain something back!” Spike protests, still mad that she no longer has her dick.

“Ugh, don’t worry I have a plan,” Twilight starts. “Basically we just need to stop doing anything sexual with anypony,” Twilight said before adding. “Except ourselves since we are already contracted with it,” she continues. “And Spike I’m sure Starlight can help you with your situation, I have to figure this stuff out,” Twilight suggests to which Starlight rolls her eyes.

“Sure, I’ll help ya Spike,” Starlight says. “Anything else we need to do or can we go?”

“No that’s pretty much it, just no sex with anypony and what not, meeting adjurned,” Twilight says before going back to her research. Starlight gets up and gestures for Spike to follow her.

The two walk out before heading to a different area in the castle.

“So whatcha need my help with?” Starlight asks him.

“Well see, it’s kinda personal…” Spike trails off.

“Ah want your cock back I take it?” Starlight says with a smug grin on her face.

“I...well.. Yeah,” Spike admits.

“Alright, I will need a bit of researching to find a permanent solution,” Starlight explains. “Most of the spells I know will only grow you a temporary one then, it will disappear after you cum,” She continues. “Plus I have to get the right kind of dick, otherwise you might be walking around with a yak dong,” she finishes her explanation before pulling out a book reading ‘Spells for your pleasure’ and opening it to a page on growing dicks for your significant other. “Gimme some time, I should have it by the end of the day,” Starlight tells Spike.

“Well alright, I guess,” Spike says before taking her leave, hoping Starlight can work her magic.

“Alright this is gonna be a long day,” Starlight says as she starts testing the spells out. Her crotch soon basic looking eight inch horse cock fit with two baseball sized balls.

Spike wanders through the halls of the castle, looking down at her inflated melons. They still hadn’t gone down yet to their regular size and she lets out a deep sigh. How did this happen? Why did it have to happen? She wondered to herself until she bumped into something very soft.

“My, my darling you simply must watch where you're going,” a familiar voice tells her. It was Rarity and Spike had just ran into her jumbo jugs head first, she immediately backs away with her face turning a full flush of red. She just had her head in Rarity’s bountiful bosom, her mind going over the limit with the thought of it. Had she still had her dick she would be sporting a full hard on right now, but instead her gash floods her panties with juices.

“O-oh sorry Rarity I didn’t see you there,” Spike tells her stammering her words as she soon starts sweating. To which was true after all she was staring at her own honkers so she didn’t notice she walked head first into Rarity’s jugs.

“It is alright darling, after all we are in quite a pickle so I understand why you are feeling a bit blue,” Rarity reassures Spike.

“Well yeah, I am feeling odd about this,” Spike admits squeezing her knockers.

“Of course, but there is one thing you should feel happy about,” Rarity tells her.

“What’s that?” Spike asks, which Rarity wraps her arms around the dragoness and pulls her into a hug.

“You are still my Spikey wikey,” Rarity says rubbing the top of Spike’s head and dragging her back into the valley of her marshmellowy boobies. Spike practically melts at her touch and being between her chest as she settles in for a moment to fully enjoy this.

Meanwhile…

“Okay, so they didn’t label which penis is which but I suppose it’s gonna be trial and error,” Starlight tells herself, before casting her spell causing her horsey member to slowly transform developing a lot of what seems to be foreskin around it and encasing the head in the foreskin. “Hmmm not the one I needed, now gotta bust a nut to start over,” Starlight notes before jotting it down on some paper. She soon grasps her foreskin clad dick and begins peeling it back before stroking her cock with the sound of her hand bouncing off her ball sack with her gliding with precision like strokes. She cups one of her gargantuan titties bringing it to her mouth as she suckles from it all the while keeping up her strokes in time with her tiddie sucking, her cock trembling due to the sensitive skin on her penis being pulled back and forth, as well as collecting any pre cum into the skin giving a gooey slimy feeling as she goes. Starlight soon slumps down onto her chair to take the stress off her legs as she keeps on fapping, letting out a soft moan which causes her to speed up. Feeling her oddly skincladded donger throb repeatedly before she bites her lower lip and her sack tightens drastically, she lets out a loud moan as her cock begins shooting the gooey cargo from her nuts painting the floor with her seed. Strings fly through the air over and over landing and pooling on the floor as she continues stroking till her dong has gone numb from pleasure, some of her cum getting caught on her foreskin and being used as lube to aid her finale of stroking. Eventually she soon lets her dick go soft as it drops covered in her own cum while her brow was covered with sweat, she wipes it and watches as the spell soon wears off and her dick and balls recede before disappearing back into her body leaving her with her pretty pink pussy.

“Okay well least that’s one spell down,” Starlight says to herself, taking a quick break before continuing.

Elsewhere…

Spike was still melting away at Rarity’s touch, if this had been a dream Spike would want it to never end.

“That reminds me,” Rarity begins quickly drawing Spike out of his fantasy. “Since you have changed from what Twilight told me, maybe we should give you a more fitting name,” Rarity points out, which honestly Spike never really thought about all that much. I mean she is hoping that it isn’t permanent and she will return to being a male dragon again. But for now she is still a she not a he, so maybe it would be a good idea to have a temporary name change.

“Huh, well how about...Barb?” She suggests to Rarity.

“Oh I simply love it, Barb,” Rarity says with a wink and a giggle. Barb giggles as well reaching for a hug again from Rarity. Despite her bodily change her love for her hasn’t changed, hopefully Starlight can at least get her a dick to use again.

“That reminds me Barb, there is something I believe we could do now,” Rarity says with a grin, to which Barb looks up with curious eyes.

While this was happening…

Starlight lets out a sigh as she prepares for the second dick spell, having already got her pony peener back once again she casts the spell. Her cock twitches as several spines start to jut out of the shaft. After the spell dies down she examines her newfound penis, touching one of the spines only to receive a prick from it.

“Ouch!” she exclaims, shaking her finger. “Seriously who the fuck would want to have sex with someone with a cat cock!?” Starlight exclaims before grumbling to herself as she jots down the effects. After she does so she is left with one question, how does she jack off with this? It’s spines will hurt her hand should she try to stroke herself off. She rubs her chin in thought thinking of a solution before she snaps her fingers. She sits on the floor before laying back and resting on her back and shoulders with while bending slightly to allow her kitty cat cock tip to boop her nose. Maybe having this cat dong made her more flexible? Who knows? But thankfully she takes the penis into her maw and thankfully her salvia makes the spines and their sharpness useless. She soon suckles to which she is awarded with a salty treat in her own pre cum. She tries to take herself deeper only able to take herself halfway before she starts gagging on her own rod over and over. As she slobbers over her prick she soon feels the telltale signs of an orgasm hot on its way as she shoots her thick wad in her mouth, causing her eyes to snap open in surprise as her cheeks bulge out to contain the nut she has just busted. She does her best to swallow the entire salty load, with some drooling out of the corner of her mouth, she soon lets the cat cock out of her mouth with a wet pop a trail of salvia connecting from her lips to her dick head. Soon like before the penis goes back into her and leaving her just with her gash once more.

“Two down, more to go,” Starlight says with a burp.

Back where a certain two big boobed gals were…

“So what did you want to do Rarity?” Barb asks, as she followed Rarity back to Barb’s room.

“Oh simple Darling just a little something, I wasn’t able to do earlier since you, Twilight and Starlight were having a bit of fun while I was having a crisis with the girls here,” Rarity points out by patting her chest.

“Wha-what?” is all Barb can mutter out as Rarity approached her, exuding a dominatrix like aura about her. Did Twilight or Starlight tell her about their little romp? And is Rarity jealous? And most importantly, is this good or bad for Barb?

Back with Starlight…

“Alright, third times the charm,” Starlight tells herself before casting the third spell. This time her rod twitches as it shifts and soon becomes very shiny and smooth as well as red, and the once blunted tip soon become rather pointy. And just above the sheath a bulge is created as it slightly inflates and she is left with a rather sizable knot. “Ugh seriously? A dog dong?” she complains, well at least it isn’t as bad as the cat cock. “Stupid diamon dog fetish enthusists,” Starlight grumbles before she starts stretching, trying to limber herself up for what she has planned. After all she had heard the comparison of knots vs horse dicks which is better, so thankfully she can see which is truly on top of the dick food chain. She does herself one last stretch before feeling limber enough to do this type of act of masturbation, males and dickgals have tried this all the time but most either end up hurting their dongs or pulling some serious muscle, funny enough she recalls Sunburst trying it and pulling muscles he didn’t know about, clearly he never heard of the ‘Please fap responsibly’ motto. But she is ready, as she puts her chair in position and gives her knotty cock a few test strokes. She uses her hands to help align her supple cunt with the pointed prick a task which is made difficult but once lined up correctly she sits on her puppy prick, getting a bit of penetration but also met with a bit of pain.

She gets up relieving the pressure before tapping her chin in thought and snapping her fingers, before going into her trunk of junk and pulling out two magical rings and smiles. She had gotten these a while ago to study their properties only to learn that they were cockrings that when infused with some magic can create two portals between the two. She uses some of her magic to activate the two rings before sliding her doggy dick into one a task made difficult by her knot and watching it pop out of the other one, to which she sets it on the chair.

With a cute wiggle of her tush, she soon sat herself down on her own cock and lets out a throaty moan. She soon settles in bouncing off the chair and riding her puppy penis, constantly avoiding taking the knot just yet, her pussy squeezes any and all pre cum out of her pointed dick and into her greedy gash. She plays with her still enlarged tits, funny that they haven’t gone down yet since they usually do after a bout of sex but for some odd reason they are still as hefty big when they grew with everypony elses, she fumbles them in her hands absolutly overflowing with tiddies as she moans out loud, not caring who hears her. She speeds up her bounces and falls constantly taking her mismatched dick whole each time but just shy of the knot each time not fully ready for what it will do should it tie itself to her pretty pink pussy. She continues moving at a feverish pace her face growing fully flushed and her booty wobbling each time she slams down just before the knot, but however she accidentally lets the knot slip past her pussy lips which causes her to moan in a mix of pain and pleasure as she soon cums from it entering her. Her spooge makes its way into her womb leaving her insides white and sticky, the knot however fully expands and anchors itself it her snatch. She quivers and shakes, as she struggles to keep her balance, soon feeling full and warm inside as she pants to catch her breath. After she finishes up her intense orgasm, she tries to get up but finds herself stuck by the knot.

“Ugh, well fuck,” she says to herself, considering she is stuck until her knot deflates and releases her so she can try again.

Meanwhile in Barb’s room…

Rarity has all but sized up the dragoness puffing out her chest, letting her true dominatrix side come out.

“Such a naughty dragon, you were to take advantage of poor Twilight,” Rarity says which confuses Barb, but little does she know Rarity is ‘in character.’ the marshmellow unicorn approaches before gently pushing the confused dragoness onto the bed, causing Barb to look up at Rarity only to be met with her soft rump immediately being sat on her face. “Now go on Barb, eat up and maybe I will let you get some air,” Rarity informs Barb with a sly smile across her face. But little does she know Barb is practically in heaven right now, she lets her dragon tongue slide across Rarity’s slit getting a taste of her delicious nectar. It is just like Barb always imagined, smothered in between Rarity’s thighs she could almost die happy now except she is still missing her cock however. But this is as close to it as she can get so might as well enjoy it right? She continues to flick her tongue against Rarity’s snatch eliciting a moan from the elegant mare.

“Oh enjoying yourself are you?” Rarity asks to which Barb nods. “Then perhaps I should try out one of those new spells Twilight taught me,” Rarity informs the happy dragon, her horn lights up as just above her well eaten pussy, her a cock starts to appear as if being molded by clay until she is left with a seventeen incher of a horse dong with a pair of apple sized nut sack. Unfortunately Barb has yet to notice, so she is in for quite the surprise in a minute, as Rarity takes one of the dragoness’s hands and bring it to her new penis. It only takes a moment for Barb to register what she is touching with a clawed hand, this in turn turns her on and she grasps the member in question and instinctively begins to stroke it. “Oh, a bit eager are you darling?” Rarity chimes, slowly feeling the blood pump to her loins making her horsey dick grow to an erect state. And Rarity was more than happy to oblige the horny busty dragoness.

Back with Starlight…

Starlight lets out an exhausted sigh as she once again casts her dick growing spell and once more has her pink pony penis. As she reads the spell and lights up her horn, she hopes this time is the right time as her cock molds and shifts into a more reptilian like design and becomes nice and smooth. Her eyes light up as she finally had done it, she is now sporting a dragonic dick! And in her excitement bolts straight to Spike’s room, completely in the nude.

Back in Barb’s room...

Rarity lifts her marshmallowy bum off Barb, and grabs the dragons legs and pulls her towards her and spreads her legs wide open before lining up her pony prick with Barbs dragon slit. This isn’t how Barb pictured her first time with Rarity would be but life just works out like that. At least it’s pretty darn close. Rarity takes the initiative and decides to spear herself in the dragon's cave, Barb yells out in pleasure and cums from the insertion alone, her juices soaking Rarity’s meat rod.

“Already? I barely even started,” Rarity says to Barb who’s legs can’t stop twitching. Suddenly the door flung open startling Rarity, which to her surprise was Starlight naked and with a mismatched cock.

“Goodness Starlight, a bit of warning before you come barging in perhaps?” she asks Starlight who looks at the scene before her.

“Oh my bad, am I interrupting something here?” Starlight asks.

“Little bit, just a casual romp in the hay as they say,” Rarity explains patting Barb’s chest.

“Ah well,” Starlight awkwardly says before using her magic on Barb. “I’m only here to give Spike her cock back and I’ll be on my way,” Starlight explains as the spell finishes and just above Barb’s snatch a mighty dragon dong and a set of balls burst forth from seemingly nothing.

“Oh my,” Rarity says before grabbing and stroking the newly formed prick, causing Barb to moan. “Say Starlight since you have that aching cock of yours, would you like to join me for a game of ‘Spitroast the busty dragon’ perhaps?” Rarity offers with a sly grin on her face.

“Well… it would be nice to get off with somepony else helping,” Starlight says before unceremoniously shoving her dragon meat rocket into Barb’s mouth. The duo soon decided to set the pace of plowing the dragoness’ mouth and pussy at a steady but fierce pace, giving Barb time to adjust to both their dongers before they get rough and wild. Barb’s eyes all but roll back as she is lost in pleasure, having her snatch clamp down on it’s invader while sucking off the Starlight to the best of her abilities. Starlight bites her lower lip and reaches forward and slaps around Barb’s tiddies which causes her to gag on Starlight’s magic wand from the stimulation, as her nipples are pinched and twisted causing pain and pleasure to shoot through her body. Rarity decides to hoof her arms around Barb’s legs and lift them up slightly as she speeds up to pound the pussy as hard as she can, eager to stretch her out till it is a perfect mold of her dick. Barb gags on Starlight’s cock while her own donger twitches and throbs despite being completely ignored and untouch,a steady stream of pre cum runs down her length and collecting into a pool on her balls.

“Oh shit, I'm gonna cum soon, you better drink it all down you slutty dragon,” Starlight warns Barb, her balls slapping against Barb’s nose each time she bottoms out in the dragons warm maw. Her sack tightening full of fresh hot foal batter to feed the hungry dragoness.

“Oh how vulgar, Starlight,” Rarity chimes in following a rough grunt at a breakneck speed of thrusting. “You must keep you composure and be ladylike at all times,” Rarity advises Starlight while pounding away at the poor dragon pussy. Starlight however is utterly ignoring her cock bearing companion and bites her lip as her eyes cross before a tidal wave of spooge floods Barb’s mouth and throat, creating an obscene bulge as she is forced to swallow the nut. Rarity sees this and speeds up even more jackhammering her hips into Barb’s as if she is so close to the finish line she can feel it literally and gives one last home runner of a slam into Barb.

“Fuuuuuuuuuuuuck!!!!” She announces to the heavens throwing her head back as she unleashes a tidal wave of cum into the abused pussy of the dragon filling her up with her precious seed, to the point that Barb soon finds her tummy growing from being stuffed from two ends with pony cum. The sheer heat is enough to make Barb join them as she shoots lance after lance of hot dragon cum in the air landing on her tits, belly, hitting Rarity in the face a few times and coating Starlight’s hair with one or two really strong blasts. The wave after wave of salty seed floods Barb to the point she looks like she is pregnant with twin baby dragons, the two ponies pull out of their messy holes and stroke themselves to finish unloading all over the dragon's body with Starlight coating her titties with her leftover nut butter. While Rarity shoots the rest of her load all over Barb’s dick.

Some time passes as the two unicorns panting heavily and recover with both their dicks receding back into them and their melons shrinking as well.

“Phew that was quite the vigorous workout,” Rarity says wiping the dragon seed off her face.

“Your telling me, this is the fourth time I had to cum today,” Starlight jokes trying to get the cum out of her hair.

“Care for a snack then?” Rarity asks her.

“Sure what about Spike?” Starlight inquires looking down at the fully cum coated dragon with cum oozing out of her vag.

“Oh don’t worry about her she is quite full, and also it’s Barb now while she is still a female,” Rarity explains to her and giving Barb’s now original size melons a playful swat.

“Ah well sure then,” Starlight says as the two take off leaving Barb on her bed fully caked in cum.

“So..worth it,” Barb says rubbing her belly full of a mix of Rarity and Starlights seed and then patting her now softening prick before passing out.
