Fresh from the source

The sun shined in on Rainbow Dash as she awoke from her bed stretching and smacking her lips. She hops up and out of her bed, and quickly jumps in for a shower in her cloud house whistling to herself. A bird flies in through to her window whistling loudly trying to get her attention as she gets out drying her newly grown longer hair, although it’s a pain and takes forever to dry. As she walks over she notices a letter in its beak, it’s from Fluttershy no doubt if anyone can ask a bird to deliver a letter it’s Fluttershy. Dash takes the letter and unfolds it to begin reading.

“Dear Rainbow Dash, I am having a serious problem and need your help. I’m at my cottage come as soon as you can. Love Fluttershy.” She read aloud, as she puts it down and sends the bird on its way. Dash quickly dresses in her Wonderbolt tracksuit before taking flight to Flutters.

Dash quickly arrives glad to get a morning flight in even if it was a short one. Skillfully landing in front of her cottage as she walks up to the door, giving it three knocks.

“W-who is it?” A soft nervous voice chimes out from behind the door.

”It’s me Shy I got your letter. Open up.” Dash calls back.

“Oh thank Celestia you came so quickly, let me unlock the door.” Shy responds, as a lock clicks and the door opens wide for Rainbow to stroll on in. The second she is in the cottage the door slowly closes behind her.

“So what was so important you needed me fo- Great Celestia’s bouncing bosom!” Dash shouts, looking at Fluttershy. “What in Equestria happened to your breasts!?” she exclaims, her friends boobs were twice the size of her head if not bigger. Fluttershy always had big boobs at an eye candy G cup but these were bigger they were at least a double J cup at minimum, and Dash can’t help but stare with her jaw hitting the floor at Flutters exposed and seemingly leaking melons.

“W-well I was buying some milk at the market, and I have to buy this special brand because I had just ran out of it and the animals really do love it. And it tastes really good too.” Fluttershy notes. “But this time I saw this one from the same brand but it was a special edition and I took a cup and my tits started growing and leaking!” she exclaims, causing them to juggle slightly. Rainbow Dash wonders what her spine is made out of to still be able to stand without collapsing under the weight of those massive udders.

“Well lemme read the bottle first Shy.” Dash says, walking into the kitchen and over to the table and noticing the two bottles. One empty and one half full. ‘Hollow’s moo moo milk’ she reads on the label of the empty bottle before reading the second one. ‘Hollow’s new moo moo milk, guaranteed to bring out the moo moo in you’ the half empty bottle reads as she turns it around and notices some of the fine print on the back.

“Warning: this milk serves as a transformative, please be sure to properly boil to remove the effects if consumed.” she reads now knowing that it doubles as a totally different purpose. “Effects may include: Sudden Breast growth, Lactating, Sneezing Tit’s, growth of unwanted set of breasts or extra breasts, sperm replaced with milk and sudden milk orgasms when scarred or panicked. Hollow’s moo moo milk is not responsible for any unwanted effects. Effects may wear off over time.” Dash continued before heading back out into the living room.

“Shy looks like you bought a similar brand that serves as a weird transformative.” Rainbow informs her, pointing at the label as she hands the bottle to which Fluttershy which causes her to exclaim in realization.

“Oh my goodness! They look the same to me that explains everything.” Fluttershy remarks, sitting down on her sofa. “Well least I know now.”

“Glad I could help Shy, I will be off now if you don’t need anything else.” Dash points out, heading to the door.

“Well there is one thing you could do…” Fluttershy, says softly.

“What?” Dash asks, which causes Fluttershy to look down at her leaking bosom and then at Dash and back, letting her fill in the blanks. “Your kidding right?” Dash asks getting what she is asking, as Shy shakes her head no.

“I can’t get to Twilight’s with these things leaking. It will stain my clothes plus they are really sore.” Shy whines causing Dash to sigh in frustration.

“Fiiiine, but do not tell anyone and you owe me big time.” she responds, causing Flutters to nod in agreement. She then moves herself into a comfortable position as she stares at Shy’s new milky assets, as her natural instincts take over and she latches on to her nipple and begins nursing from her. Shy moans softly at the stimulation as rivets of her milk pour straight into Dash’s mouth, as she gulps it down as quickly as it comes into her mouth. Feeling like a newborn filly drinking her mother's tasty milk as she continues to guzzle down what feels like litres of Shy’s milk. Her tummy slowly gaining a bit of a paunch from all the milk feeling well beyond filled.

“Hehe feels nice huh? Little Dashie needs to drink up to grow up big and strong.” Shy teases, as Rainbow looks at her as she pops off and goes to the next tit. Shy soon slowly gently brushes the back of Dash’s head as she nurses from her. Shy sighs happily feeling the weight being lifted from her chest. Dash feels her belly stretch and swell as more and more milk fills her stomach. “This feels rather nice maybe we could do this more often huh?” Shy teases, causing Dash to respond by adding a bit of teeth to her sensitive nipple. “Ow! Okay okay I was joking. Please they are very tender.” Shy whines, as Dash relieves her teeth and returns to suckling the teat. Dash feels full and pops off looking at Shy and then her new formed belly, she will need to work out extra hard to lose this milk weight.

“Ugh I think I’m gonna be sick.” Dash says rubbing her tummy.

“Don’t worry let Mama Shy take care of it.” Flutters teases, putting Rainbow over her shoulder and patting her back to make her burp.

“Come on Shy I am not a little fill- URP!” Rainbow says, as she is interrupted by her loud burps that Fluttershy is forcing out of her. Embarrassing Dash a tad being burped like a little filly after a feeding. After several light pats and several loud belches later, Fluttershy let’s Dash go.

“All better thanks to Mama Shy.” She giggles to herself.

“Very funny Fluttershy, I gotta go now and try to work off this milk weight.” Dash huffs, walking to the door but stopped by Shy.

“Bye thanks again Dashie.” Shy says, giving her a kiss on the cheek. “I’m gonna see if Twilight can help me out with reversing this.”

As Dash leaves and heads home she struggles with her newfound weight making it all the more harder to be in the air which takes her twice as long to get back. As she lands at her cloud house and enters only to groan while looking at herself in the mirror.

:I gotta ditch this weight fast if I’m ever gonna make it as a Wonderbolt.” She notes, to herself hearing Fluttershy’s milk sloshing around as she makes her way into the bedroom planning on sleeping this off or the rest of the day until she can get rid of it. As she hops in her bed feeling her milk ocean splash around in her making her feel a bit queasy. She soon sighs sadly as she closes her eyes and drifts off into a nap.

Dash takes flight with the Wonderbolts captain, Spitfire and the new fellow recruit Green Thunder as they soar through the skies doing a lot of skywriting in their wake. They soon land back in Cloudsdale after there routine morning workout.

“Great work team were finishing our workouts in record time!” Spitfire remarks, giving the two a
congratulatory smack on the butt.

“Thanks Spitfire we totally crushed it!” Green responds excitedly.

“Totally I can’t wait to beat those Shadowbolts in the big race meet next week.” Dash responds, as her suit begins to feel a bit tight, especially around her chest. She looks down to notice her once perky set of D cup breasts are growing and fast! “Wha-what the hay is happening!?” Dash exclaims as the fibers slowly strain trying to contain her boobflesh, but alas it cannot as her boobs grow from double D to E and then to F as the fibers give way as she reaches G cups. Her blue tits burst forward as she blushes heavily and Spitfire and Green stare in awe of the event. Green’s jaw drops and his tongue falls free while a bulge forms in his suit clearly turned on by Dash’s new assets to match her new long ass length rainbow hair. Spitfire stares feeling a little insecure about her own double D’s. Rainbow’s bouncing bosom stops growing around a double H cup and as she stands there embarrassed of the situation. And as if the situation couldn’t get any worse her breasts feel even heavy as she tries to stand up straight her tits flop about and soon begin leaking milk at an alarming rate. “B-breast milk too!? Why is this happening!?” Dash exclaims, as Spitfire closes the gap and hefts one of her tits and begins flicking her tongue against Dash’s nipple.

“Mmm this is pretty tasty rookie. Thunder! Come have a taste, double time.” Spitfire tells him, soon latching on to the blue nipple making Rainbow blush even more.

“Yes ma’am!” Green excitedly replies as he rushes on and begins suckling all the while grinding his boner into Dash’s leg. Rainbow quickly turns from blue to crimson at the duo nursing on her newly acquired massive mammaries, gulping down hearty helpings of her liquid. Spitfire soon pops off her melon and wipes her mouth.

“You know rookie there might be a place for you in the Wonderbolts after all...as our milk cow to give us all the milk we need.” Spitfire says before heading into the barracks. All too soon a bunch of the Wonderbolts come out and form a line in front of her. “Alright everyone remember two at a time, five minutes to get your fill our tit cow ain’t going nowhere!” Spitfire instructs as a Bolt latches onto her tit and begins sucking getting his fill. Spitfire soon blows a whistle at Green who kept drinking well past his limit. “Green! You had more than your fill save some for the others!” Spitfire booms at him as he is yanked off trying to struggle.

“Awww please I wasn’t done, I need some form of release now.” he whines causing Spitfire to roll her eyes and look at Dash as she tears open a hole in Rainbow’s lower half of the suit exposing her slit.

“Alright then revising! Males who are feeling pent up can use our new cow to shake off some of that pent up weight in their sacks! But cum quickly others need to use her.!” Spitfire orders as Soarin goes right under her while Dash falls to her knees. Dash turns redder by the minute, is this what it takes to get her in the Wonderbolts to be used as a cow for milk and release? She questions but is interrupted by Green shoving his prick in her and goes to town on her. Dash moaned loud secretly loving this as another recruit pops off her nipple but is quickly replaced. Spitfire soon locks lips with Rainbow giving her some tongue action. Dash was swimming in lust slowly understanding her situation. She would be a real contributor to the Wonderbolts now by feeding them and helping release any tension the males might have. And what if she gets pregnant? Simple she would get to birth tons of future Wonderbolts! Afterall with her athleticism and coolness mixed with another Wonderbolt would be an awesome combination for a flyer. This causes her to get excited and start bouncing back against Green as the two Wonderbolts are once again replaced.

“Nngh fuck she is tight~” Green moans while the other males looking for relief have all but freed their own respective meat and are preparing for their turn. Dash moaned into Spitfire’s mouth loving the idea of serving the Wonderbolts, granted not in the way she expected but this is just as good. She could set tons of records here for the first time like most cocks taken in one session or most milk milked.

“I see big things for you here rookie.” Spitfire says pulling away from the kiss leaving Dash searching for air. As Green throbs and cums inside her, she could definitely get used to this…

Dash jolts herself upright sweating heavily panting and looking around. So all that at Cloudsdale and the Wonderbolts must have been a dream probably a result from all the milk she drank. She quickly gets up and stretches her limbs only to feel more weighty around her chest. As her eyes open and her vision clears. She lets out a shriek of terror. Her tits are still the same size from the dream. How did this happen? Was it Fluttershy’s milk that did this? Her milk belly is gone but she still has jumbo sized jugs, and her crop top now looking more like a bib. She hefts her newly enlarge breasts in her hand silently whining, these are so not aerodynamic they weigh her down more than anything. She soon rolls them around in her hand, they do feel kinda nice however so soft and squishy. Doing so elicits a small moan from her, she does have some free time so maybe this won’t be totally bad right. Plus that dream did put her in that kinda mood.

She flops back and begins massaging her breasts, letting her hands roll every inch of new titflesh and brush past the nipples repeatedly. She softly moans trying to recall the dream as best she can as she does so she reaches her nipples pinched them softly letting a loud moan escape from her lips. She soon repeats this action then starts tugging on them and letting them go as they flop back into place each time. All the while he ignored supple cunt gushes more liquid staining both her panties and sheets. She was horny and she needed somepony to take her now! But who would do so? Is there someone she could booty call? Or maybe…

“Rainbow Dash! Are you home!? You didn’t show up when you said, so Applejack sent me to get you!” a voice from outside shouts.Bingo her prayers have been answered. She remembers she was supposed to help her with a repair at Sweet Apple Acres. Since Big Mac pulled his groin he couldn’t help. Probably pulled it from one of the mares he was with the other night, she imagines with a snicker.

“Dash you home? It’s me Green!” the voice yells from outside. Dash licks her lips. It’s Green Thunder the pegasus who Dash just dreamt about, what are the odds? This is perfect she is pretty sure has a huge crush on her. After all judging from the huge nosebleed he had from when he helped her pick out a nice naughty nightie for when she feels like getting kinky before bed. He sat there like a trooper complimenting every single one with a huge gush of blood running down his nose. He must have had a good fapping session when he got home later that day. Dash starts to weigh her options after all she is still a bit horny from her wet dream. So maybe it won’t be so bad I mean he has probably fantasized about it before.

“Yeah the door is open come in!” she shouts back, giving him the okay to come in. as she finds a rather seductive pose to accent her newly acquired chest girth. Thunder strolls in looking around. “I am in my bedroom! Mind coming to help me with something!” she calls, baiting him in to her booby trap.

“Yeah after we’re done with whatever you need help with we need to get to- Sweet Mother of Bah-Rest!” he exclaims viewing the sight. Dash was sitting there buck naked her tits on full display and her legs crossed on the edge of the bed. Green’s wings fully extended clearly showing the blood is rushing everywhere else but in his head. Was he dreaming? Is this real or a fantasy? Whatever it is he is extremely happy.

“So Green see something you like?” she asks, performing a Rarity like hair flip knowing the answer but gains several nods from him. She cranes her finger beckoning him in as he dumbly follows, listening to the head in his pants. “I need you help with my hair mind giving it a brush?” she asks, knowing he was the one suggesting she should grow it out. She isn’t sure why exactly but he liked her ass length long rainbow hair.

“S-sure!” he dumbly says, as he stumble over to her as his jeans have a slight bulge from his member pressing against it, Dash turns around handing him a brush as he soon begins brushing her hair, he was an utter wreck sweating his mind racing. Is this a dream? If it is he hopes he never wakes up. He brushes her hair over and over getting to feel her soft and silky locks of hair, he loved every second of it! Dash soon turns around and stares at him before he gets grabbed by Dash and dragged into her valley of cleavage. Nearly suffocating him between her soft pillows. Her arms embraced him in a hug as he was enveloped by her blue titties, she sneaks a hand down to feel his bulging member through his jeans, before fumbling to pull them down exposing his green footlong horse dong.

“So I wonder how long you have been fantasizing about me Green, how long you wanted to be here in my bed with me, because I know you have been crushing on me for the longest time. And now you get to make those fantasies become a reality~” she says, seductively as his cock throbs once in her tight grip. She steadily begins jerking him off while he motorboats her fat cow girl like melons. His dick quickly produces pre cum which causes her to snicker and spread it all over his meat. “Eager aren’t you? Well let’s skip the appetizer and go right for the main course~” she tells him, in a husky voice letting him out for air as she lies back and spreads her legs open wide for him to view her glistening snatch.

“Can do Dash!” Green says, pulling off his jeans and shirt and climbing on top of her. The heat of his member combining with the heat of her warm wet slit as he soon slowly sinks into her. His green horse meat disappearing into her blue cunt. A look of pure ecstasy spreads across both ponies faces as their wings fully extend while Green soon starts getting in rhythm with his dicking of her. His balls slap against her entrance coating them with her female juices each time he bottoms out inside her. The room fills with moans, and wet meaty slaps while Green latches onto one of her nipples suckling it as a small rivet of milk fills his mouth as he pounds her. His hips moving on their own at this point as he continues to drink from her like a baby with Dash cooing him on. Dash loved the feeling of getting stuffed by his green pecker finally scratching that itch she needed to scratch.

Each time again he slides his hands underneath her to feel her hair occasionally and to cup her toned bottom.

“Like my hair that much huh?” Dash asks after feeling his hands roam down there and lifting her slightly.

“I ngh, just like the feeling it is all.” he says as he continues to thrust in and out reaching to give her boobs a hearty squeeze.

“Very well carry on~” she teases, as she begins flexing her vaginal muscles to squeeze him more tightly at random times this causes him to moan louder and for his dick to squirt out a dose of pre cum for Dash’s hungry snatch to devour. As she bucks back and bounces off his lap each time earning an appreciated moan from him. His face soon turns into a goofy happy grin causing his tongue to fall out as his wings fully extend and begin flapping on their own. He definitely was enjoying this Dash knew he thought about this before to be balls deep inside her pounding her to his heart's content. “Come on Green pick up the pace a bit! Let’s see how fast you can go~” she teases him, begging for him to speed up. He complies as his hips begin pistoning into hers with such great speed as he fondles her tits groping them each time he can. He leans back down to suckle more of her milk giving himself his own little milk paunch from feeding too much from her delicious warm breast milk nectar. The scent of sex filled both of their nostrils as Dash’s eyes rolled into the back of her head as he kept grunting each time he thrusted in closing in as he was about to reach his peak.

His horse member’s flare extending stretching her walls even further as his balls tighten as his cocks veins bulge and cum flows out of his flat headed tip painting her inner walls white. Dash moans as she bites her lower lip and cums along with him her walls squeezing him in a vice to milk every single drop of spunk. He pops off her tit panting as he soon collapses into her tits, having a nice soft landing after he spent everything he had in one go, he soon lets out a small burp from all the breast milk he drank. As they lay their in the afterglow of their respective orgasms for several minutes.

“So think you can handle another round Green?” Dash asks him.

“You know it!” he exclaims as he starts moving his hips again.

Meanwhile at Sweet Apple Acres…

“Where the hay are those too!? Ugh I’ma kick both your butts for this!” Applejack shouts in anger.”Ya hear me you two! Ya’ll are lucky I ain’t got wings!”
