Drinking Her Way to a Bigger Dash

 

While Fluttershy goes to take a shower, Dash goes hunting for a snack. She finds some cookies and scarfs them down. Thirsty, she looks for something to drink in the fridge and sees a bottle of milk. It doesn't have a label but it smells okay. She drinks it and it tastes delicious, although it's obviously not cows milk.

 

Wondering what kind of milk it was, she intercepts a towel-clad Shy as she is headed back to her room to get dressed.

 

At first Fluttershy is puzzled.

 

"Milk?" she wonders, saying that she doesn't have any milk in the house. Then she blushes bright crimson. She refuses to tell Dash what it is until Rainbow all but forces it out of her.

 

"It's my milk!" she cries.

 

"Huh?"

 

The busty girl explains that ever since the incident with Sunset Shimmer and the magic of harmony that she has been going through some changes, the biggest one being that she has started producing milk.

 

Now she has to pump her chest at least twice a day. Usually she pours it down the sink, she explains, but lately she's been wondering if she could do something useful with it, so she kept a bottle.

 

That is what Rainbow Dash drank.

 

The thin athlete is, of course, horrified. She gags but, not wanting to hurt her friend's feelings, eventually reassures her mortified host that it was just an accident and that everything will be okay.

 

They both head into the room and Rainbow asks about Shy's breasts and just what's happened to them. Fluttershy is in the middle of getting dressed when Rainbow inquires. Trusting her childhood friend, Fluttershy decides the best way to explain is to simply show Rainbow her development.

 

The busty girl opens her towel and lets her shocked buddy look at the changes that she's gone through over the past few months.

 

Dash can't believe it. She knows that they were big, even when she saw them at the pool the previous summer. She also knows that they have grown, despite Fluttershy hiding them under bulky sweaters. But actually seeing them is something else!

 

The dusky circles capping Shy's breasts are a light chocolate color. Her nipples are much longer and thicker then Dash remembers them being too.

 

The breast themselves have swollen from large handfuls to ridiculously full bazooms and their shape has changed as well. Before, each breast was pendulous and rested comfortably against Fluttershy's rib cage. Now each of the growing girl's gazongas jut from her chest in an almost unreal fashion, causing Dash to realize what she thought was the work of an amazingly supportive bra is really just the shape of Shy's amazingly full tits.

 

Rainbow has to catch herself as she almost reaches out to touch her friend's fantastic chest. It's not a sexual attraction, more like a simple fascination with the bobbling shapes before her.

 

With the inspection over, an embarrassed Fluttershy continues getting dressed and they both turn in for the night.

 

As the night wears on, Rainbow Dash's body begins to react to the bellyful of milk she drank earlier in the evening. The front of her shirt begins to shift and pucker as two distinct shapes make themselves known under her tank top.

 

The next morning Fluttershy wakes up to the sound of her friend's screaming.

 

Rainbow Dash has her tank top rolled up and is staring at her...

 

Breasts?

 

That can't be right. Fluttershy rubs her eyes and looks again. Sure enough, her previously flat friend has a pair of moderate bumps rising from her chest. Actually, she notices that there's something a little unusual about them.

 

Instead of being the same creamy white as the rest of the flesh beneath Rainbow Dash's bikini line, the modest mounds are a pale pink. Almost as if...

 

"I just woke up and my nipples were huge," Rainbow sobs.

 

Fluttershy then realizes what has happened. During the night her friend's areolas have developed and spread out across her chest! Looking closer, she can see that Rainbow's nipples are still relatively small and are now sunk into the domed mass of the larger pink circles surrounding them.

 

Fluttershy speaks to her friend and gets her to calm down. She explains that the blushing bulls-eyes on her torso aren't her nipples, but rather her areolas. Rainbow finally stops freaking out when her friend explains that lots of women have breasts that start their growth this way, with the areolas and nipples growing first and then the rest following later.

 

"But they're so weird," she cries, "Why did they get like this?"

 

After a lot of thought (neither of them are Twilight Sparkle after all) they decide that it must be due to Fluttershy's milk. "Not that it matters," Rainbow sighs, "What's done is done."

 

After the shock wears off, they start to get dressed. Dash wonders what she's going to do about her new assets. She's never even needed a training bra before and now she looks like she could use a real one!

 

Fluttershy fishes out an old bra of hers, an A-cup that fits pretty well. Dash tries it on and find that her new additions are somewhat sensitive. It's a struggle for her to ignore the uncomfortable sensation of her paps rubbing up against the cotton cups.

 

It's Saturday morning and the pair decide to hangout at the house in hopes that they can get a handle on the sudden changes that Rainbow's gone through.

 

They play some video games and watch T.V. but it's obvious that Dash is distracted. As the morning passes, Fluttershy begins to fidget and she looks more and more distressed.

 

Finally she stands up and hurriedly excuses herself. Guessing what her friend is doing, Dash walks over to the closed bathroom door and listens.

 

Very faintly she can hear the sound of a small motor and a 'sup, sup, sup' sound. Obviously Shy is milking herself.

 

While she waits, Dash ponders her situation. She lifts her shirt and pulls her new bra forward far enough to see the peach colored lumps on her chest.

 

"Well, at least they're something," she muses. Still, they seem badly imbalanced. She's seen other women's breasts before and she has never seen a pair that had so much (What did Fluttershy call them? Oh yeah.) areola and so little boob.

 

Then she remembers her friend's words about how lots of boobs start out like that when they start growing. But she only started growing because of Fluttershy's milk! Does that mean that she's going to be stuck like this for the rest of her life?

 

At the same moment that this thought strikes her, Fluttershy opens the door. In her hand she holds a bottle of white creamy breast milk and Rainbow Dash knows that it's the answer to her frantic question.

 

"Flutters, I need to try more of your milk," she begs. Her friend refuses out of hand, but Rainbow is relentless. She explains her logic, about her breasts needing more milk to achieve a balanced, healthy look. Her friend is still very reluctant.

 

"But your areolas are already so big that if you want them to look, um, 'balanced' then the rest of your breasts would have to grow a lot. And we don't know that my milk won't just make you areolas grow bigger," she counters.

 

"Please Shy, I've got to try. Just one more time to see what happens."

 

Slowly, Fluttershy agrees. She hands over the bottle, praying that she's not making a huge mistake.

 

Dash holds the milk, still warm, in her hands. Before she can consider the full ramifications of her decision, Rainbow Dash does what she always does: charge in without a second thought.

 

To her friends amazement, the lithe athlete chugs the entire pint-full of milk in one go. Gasping a bit as she pulls the bottle from her lips, Rainbow grins at her friend.

 

They go prepare and early lunch after Dash declares that she's starving and, after they eat, sit down on the couch to watch a movie. As the film drones on they both nod off into an impromptu nap.

 

When they wake up a few hours later both young women feel a great pressure in their respective chests, though for different reasons. Fluttershy can feel the familiar fullness that comes from her mammaries needing to be relieved. Rainbow Dash on the other hand feels a binding sensation across her ribcage.

 

"Ow, ow, ow!" she gasps as she sits up. It's obvious by the indentations created by her bra that her tits have grown once again. With Fluttershy's help she gets her shirt off. Both stare at Rainbow's chest.

 

The thin cotton brassiere does little to disguise the increased mass of Rainbow Dash's boobs. Creamy flesh pokes out from all around the sides and bottoms of her petite cups. In the center of the white triangles are two stubby protrusions tenting the cloth. The otherwise slim girl can hardly believe it.

 

"Help me get this off," she wheezes. Pulling hard, Shy manages to undo the hooks on the back of the bra. Rainbow sighs in relief as the surprisingly strong piece of lingerie goes slack.

 

Warily, she slips the constricting garment off her chest. Rainbow gulps and nervously looks down to see what changes she has experienced.

 

She sighs with relief. It seems as though her areolas haven't gotten any bigger. Instead the increased mass that was straining her top seems to mostly be centered in her breasts proper.

 

Carefully she reaches up and pokes at one of her mammaries. "So soft..." she mutters. The rounded, shallow bulk of her new boob flesh has spread across her chest. Now her swollen areolas rest on top of the larger hillocks of her pale breasts, giving them a slightly more natural look.

 

Delighted that her tits are beginning to look a little better, Dash continues the exploration of her new front parts. As her fingers work their way in towards the center of her rosy mounds, the growing girl notices the twin nubs that had caused her bra to poke out earlier.

 

Whereas before her nipples had been swallowed up by her oversized areolas, they now the seem to stick out a normal distance from her breasts. When she brushes the soft tabs with fingertips, however, the adventurous young woman gets another surprise: two in fact.

 

The first is the strange sensation that courses from her nipples, causing her to shudder. She has heard that women's breasts can be sensitive, but experiencing it was a whole other thing!

 

The second surprise comes when she feels her nubbins push out unexpectedly against her fingers. She glances down to see her tips growing more and more turgid. They lengthen and she can swear they darken into a deeper shade of red.

 

Cautiously, she pinches them lightly between her thumbs and forefingers. To her astonishment they are no longer soft and rubbery. Even thought the skin is pliable, both nipples are now quite stiff!

 

And, she realizes as she kneads them a little, they feel better than ever...

 

"Ahem," Fluttershy interrupts delicately, a blush on her face. "I, um, I'm glad they balanced out some." Dash agrees, her own face scarlet at being caught playing with herself. "I, uh, really need to go, um, relieve myself. Will you be okay?"

 

Rainbow Dash assures her pal that she'll be fine, so Fluttershy gets up and heads to the bathroom. As she watches her go, Dash has a thought.

 

"Hey Flutters," she rolls off the couch, "Do you mind if I come with?"

 

"Come with?" Shy parrots, not understanding.

 

"Yeah, if it's okay with you, I'd like to, um, see how you, y'know, milk yourself."

 

The brash girl is certain that she has never seen her bashful friend blush so hard in all her life. She immediately goes in to damage control mode, trying to explain to Shy that she simply wants to see how it's done. She goes on to say that she's never really thought about all the stuff that goes along with having breasts since she's never had them before. Rainbow simply wants to see how Fluttershy handles her own bust.

 

Slightly mollified by her friend's explanation and sincerity (and Dash reminding Fluttershy that she has already seen her friend's naked breasts and turnabout is fair-play) the bosomy maiden agrees to let Dash watch her drain her milk tanks.

 

Inside the bathroom the skinnier girl takes a seat on the toilet while Fluttershy sits on the edge of the bathtub and opens the cabinet under the sink. She pulls out a fat cylindrical contraption with a plastic cup on the end. Carefully lifting her shirt up over her broad chest, Fluttershy reveals her heavy duty bra. The thick beige cups look tight as a drum to Rainbow Dash's eyes and the smaller girl gets a reminder of just how gigantic her friend's hooters really are.

 

With a practiced motion, Fluttershy unhooks the nursing flap on her right cup and reveals her swollen teat. Already there is a drop or two of white liquid dribbling down her fat nipple.

 

"They make bra's that detach like that?" Rainbow asks in wonder.

 

"Uh, huh. Makes nursing easier. Of course usually only mothers wear them," a light blush dusts Shy's cheeks.

 

"Aw you're plenty motherly, Shy," Rainbow says without thinking.

 

"R-really?" The buxom girl's blush deepens.

 

"Yeah," the oblivious Rainbow continues, "The way you take care of everything, all your critters. You're so kind to everyone. Heck I'll bet you'll be a fantastic mother someday."

 

"Well, I do like taking care of children as well as animals," Fluttershy demurs.

 

"Heck yeah," Rainbow is on a roll, "I wouldn't be surprised if you were such a natural at it that your body decided to get a head start on the whole thing and that's why you're making milk!"

 

Fluttershy seems to think about this for a moment, "I... guess that's possible. Well, I'd better show you how this is done." She flicks a switch on the machine and Dash hears the familiar whirring sound from before.

 

Holding her right breast steady with one hand, the nursing girl applies the plastic cup of the machine to her teat. It vacuums itself to her bloated boob and almost immediately milk starts to spurt out of the milky gland. the rhythmic cycle of the breast pump causes the motherly fluid to come in fits and starts. After a minute of the repetitive act, Dash grows bored.

 

"How long does this usually take?" she asks.

 

Fluttershy responds anywhere from ten to twenty minutes. Not knowing what to do with herself (and not wanting to explore her new boobs in front to of her friend) Rainbow explores under the sink. There she finds a second breast pump.

 

Rainbow asks why Shy doesn't use the second pump and the girl explains that her boobs get so swollen and tight that sometimes the cups of the nursing machine can't make a good seal, so she needs both hands to handle just one breast.

 

Looking at the second machine, Dash innocently offers to help her friend out by holding the other machine for her.

 

Fluttershy, of course, refuses but Dash presses the point, saying they can be done twice as fast. Fluttershy finally agrees.

 

Holding up the second machine Dash flips it on. Listening to her pal, the novice milker places the cup on Shy's swollen left tit and goes to work.

 

Rainbow finds that, sure enough, the taut skin of Shy's full teat makes it hard for the plastic pump to get a good hold. With little thought she crouches down and puts a hand under the protruding breast to hold it steady while she maneuvers the suction cup into place.

 

After the seal is formed and milk starts flowing, Rainbow realizes that she's essentially just groped her friends boob. She looks up but Fluttershy doesn't seem concerned. In fact, she's not even looking at her. She has her eyes closed and seems to be off in lala land.

 

Glad she hasn't offended her pal, Rainbow continues milking. As the milk flows, she looks down at her still bare chest and considers her own situation.

 

Her breasts are looking better now, but they are still far from ideal. Her areolas are still too large compared to the rest of her breasts. Beyond that, there is the fact that she now has a way to ACTUALLY MAKE HER BOOBS BIGGER LITERALLY STARING HER IN THE FACE!

 

What reasonable girl could resist that?

 

Finally the pumps start cycling air instead of liquid and Fluttershy flips the switch and pulls the nursing machine of her significantly softer right breast. Dash does the same a minute later. As she does she sees that there is still a dribble of milk running down the large teat.

 

Almost on instinct, Rainbow Dash darts her head forward and licks the stray droplets up with her tongue. Then she realizes that she has just given her host's nipple a tongue bath and proceeds to freak out.

 

"OhmygoshFluttershyIamSOOSorry!" she rants.

 

Fluttershy, surprisingly, doesn't seem terribly put out.

 

"It's okay Rainbow. You weren't thinking. It's okay." she comforts her friend.

 

When RD realizes that Shy's not mad at her she calms down, though she's still mad at herself for doing something so dumb.

 

"Actually," Fluttershy admits, "I was thinking about what you said earlier. About being motherly? I just thought, when you did that, that I felt very motherly."

 

"I know but, huh?" Rainbow catches herself. "It-it did?"

 

"Mmn-hmn." Fluttershy nods her head and looks away. "I guess what I mean is, don't worry about it."

 

"Okay." Dash agrees.

 

They both stand up and Fluttershy unscrews the bottles with their cargo from the breast pumps. She carefully pours one of the containers into the other resulting in a nearly full bottle. As she does, Rainbow Dash thinks about what she wants to say next.

 

Finally, "Hey, Flutters. Um, I was thinking, my breasts are looking better, but they're still looking pretty goofy. I was thinking that maaaaybe I could... drink some more milk? Just to even 'em out a little more?"

 

Fluttershy sighs, almost as if she is expecting her friend's question. "Rainbow, I don't know if that's a good idea..." She looks at her companion who's staring at her with the power of a dozen sad puppies. Unable to resist, she hands over the bottle full of milk.

 

Delighted, Rainbow thanks her benefactress. She quickly gulps down the nearly full bottle.

 

As the bustier girl closes up the flaps on her nursing bra, Dash grabs her own t-shirt and puts it on. The result is a rather lewd display. The shirt, intended for boys, stretches across her newly expanded chest and clearly shows off every contour of her new breasts and nipples!

 

Fluttershy giggles, "Looks like we need to get you some bigger clothes. Come on, I think I've got some things that will fit you."

 

Making their way back to Fluttershy's bedroom, she digs around in some boxes and fishes out a couple of bras. They're definitely bigger that the one she gave her friend earlier.

 

Rainbow Dash tries one and finds that it's still too small. The next one, a light blue number with lacy trim fits pretty well. The full cups seem to cradle her newly sprouted breasts better than the previous undergarment Fluttershy had lent her. Slipping it off again, she looks at the size tag which reads 28C.

 

"Holy cow," she mutters, "A C-cup!"

 

"Yes, that was one of my bras from, um, junior high." Fluttershy says.

 

"Well, it's bigger than anything I ever expected to wear. Heck, I think it's a bigger size than my mom wears!" The burgeoning girl straps her new brassiere on and takes the oversized t-shirt that Fluttershy hands her. "Man, I look hot!" Rainbow crows as she wiggles her chest, looking in the mirror and delighting in how the loose top drapes over her protruding front.

 

"I'm glad you're happy with them," Fluttershy says, "Now, how about we go get some supper."

 

After dinner they play some games and talk about the gossip at their school. At one point Fluttershy suggests that they talk to Twilight Sparkle the next time she come to their world about the odd things that have been happening to their bodies. Finally the hostess lets out a big yawn signaling that it's time for bed.

 

As they prepare for bed, Rainbow pulls her shirt off to find that her new bra is now cutting slightly into the curve of her bosom. Taking it off, she doesn't see too much of a change in overall size, though her boobs do look a bit fuller than they were earlier in the evening.

 

Her nipples are a different story. The blunt bumps have not only grown longer, they've gotten thicker too, about the diameter of dimes. She wants very much to play with them and see how big they get when aroused, but with Fluttershy in the room she simply puts on a sleep shirt and crawls into her sleeping bag.

 

After the lights go out and she hears the faint snores of her hostess, however, Rainbow's hands fly to her tits. She starts tugging at her teats through the thin fabric of her shirt. To her immense satisfaction she can feel the soft nubs harden into stiff peaks perfect for pulling on.

 

In the dark she can't see what they look like, but she knows they're big. Big enough that she can almost wrap a thumb and three fingers around each one! And they feel good. So good that she continues groping them till she falls asleep.

 

As an athlete, Rainbow Dash is used to getting up early. As the first ray of sun peeks through the bedroom window, her eyes pop open.

 

Stretching, she can feel an unfamiliar weight on her chest. Puzzled she looks down and sees a large bulk hiding under her sleeping bag. Her brain chugs along until she remembers everything that has happened. She's lays there, thinking.

 

There's a very good chance that her already sizable breasts have gotten bigger during the night, thanks to the milk she drank right before dinner. The question now: is that a good thing?

 

She's never been openly envious of girls who have big breasts. In fact she has never really felt slighted by the fact that, up until now, she was as flat as a board. Breasts have always been things that other girls deal with, not her. At least, not until now.

 

But getting to see her own mammary glands develop, like some kind of crazy high-speed puberty, and watching Fluttershy care for her own amazing endowments has given Dash a new appreciation for just how awesome boobs really are.

 

Of course if they get too big then that could inhibit her athletic prowess. On the other hand they make really good sports bras nowadays. She thinks about all the tennis stars who have large tits. They seem to do okay.

 

Having reassured herself a little, Rainbow feels ready to see what the damage is. She lifts the flap of her sleeping bag up and looks at her chest.

 

The first thing she notices is that there's a LOT less slack in her t-shirt then there was the night before. Once again her nipples are clearly outlined by the stretchy cloth. The spread of her chest causes the fabric to ripple between her fat tips, forming a line across her bust.

 

Slowly, Rainbow Dash sits up. She makes her way over to the mirror and draws the taut shirt up over her corpulent chest. As she does, she inadvertently hoists her tits up as well. When they slip free of their cloth prison they fall, slapping heavily against her chest.

 

Surprised by the unfamiliar sensation, Dash gasps out loud. When her boobs come to a rest, she finally gets a good look at them.

 

The developing girl had thought her breasts were big the night before. Now she realizes that, while those C-cups were a decent size, the massive things she's staring at now are BIG!

 

To be sure, they're still nowhere near as large as her friend's hefty hooters, but it doesn't matter. On her lithe frame and narrow chest they look positively ginormous!

 

She turns to the side to get a better sense of their size and shape. Yesterday her tits had been the definition of perkiness. They had absolutely no sag and were the shape of shallow soup bowls. Her current jugs still stick out from her torso with youthful firmness, but they've simply grown too big to fully support themselves and the soft underside of each breast folds slightly against her ribcage.

 

Having seen Fluttershy's milkers, she half expects hers to be a similar shape, but that's not the case. Her friend's sweater puppies thrust from her chest wall and both tops and bottoms are equally round and full. In fact, each of Shy's boobs are shaped sort of like an American football that has been cut in half and way overinflated.

 

In contrast, Dash's tits gently swoop out from below her collarbone. Each gland is fuller underneath causing her nipples (which have gotten a little wider but haven't gotten longer, thank goodness!) to point upwards slightly. It appears to her that the 'upper slope' of each knocker is supporting its weight much like a suspension bridge.

 

Carefully, Rainbow runs her fingers over her increased eye candy. Her areolas haven't grown, but they are different. They stick out less from her breasts and have taken on a deeper shade of pink.

 

Cupping each boob in her hands she plays with them a bit. They're surprisingly heavy, like a ripe pair of fruit. Jiggling them back and forth, she grimaces at the feeling. The athlete's not used to having parts of her body that she can't control directly. The wobbling mounds coming off her torso have all the sensation of her other limbs (and then some!) but none of the muscle. They just move about when she twists and turns. If Dash didn't understand the need for a supportive bra before, she does now!

 

Even though they are ungainly and will surely be inconvenient, the suddenly busty girl can't help but be excited. She has breasts, no, she has tits! Huge ones, too. Grabbing her latest bra she rests the cups against her large lumps. A grin crosses her face. She doesn't know what size she is, but it sure isn't a puny C-cup!

 

Listening, Dash can still hear Fluttershy snoozing. With a sly look, Rainbow sneaks across the room to the box that her friend has been pulling hand-me-downs out of. Sure enough, inside she finds a pile of lingerie. Just how many bras has Shy gone though? she wonders.

 

Crouching down, she picks though the lacy heap. One of the first garments she picks up is a modest looking D-cup. After trying it on, she's not terribly surprised to find that it's too small. A bit more searching yields a DD-cup. After adjusting the band to it's narrowest setting, it fits snugly. Stretching her hands above her head, she whimpers at the cool sensation of the satiny cups caressing her womanly assets.

 

As Dash adjusts her new brassiere, another set of whimpers reaches her ears. It's Fluttershy.

 

Padding over to the crying young lady, Rainbow can see tears streaming down her friend's face. That's not all she can see!

 

There are two wet patches staining the bed sheet that's covering Fluttershy's chest. She's leaking milk!

 

Rainbow gently shakes Fluttershy awake and the poor girl begins to sob in earnest.

 

"My chest hurts so much!" she moans.

 

Pulling the bed sheet off of the crying young woman, Rainbow Dash pauses, her mouth hanging open.

 

Last night, she thought she had seen her friend's milk bags at their fullest. She was wrong.

 

Fluttershy's button-down pajama top is sopping wet with milk. Between each button is a diamond shaped gap where the two sides of her shirt are being pulled apart by the massive bulk of her distended mammaries.

 

Helping her distressed friend to unbutton the constricting top, Rainbow Dash can't help but notice the real heat coming off the overfilled glands. It almost feels like a fever.

 

When the shirt finally comes off, Dash is shocked yet again. Fluttershy's melons, the biggest she's has ever seen, are sticking STRAIT OUT OF HER FRIEND'S CHEST! Despite their great size there is absolutely no slack in the voluminous volleyballs. The skin, with it's faint network of bluish veins, is stretched and quivering. The painfully full bosom is flushed and throbbing.

 

"What can I do?" Rainbow croaks. She can't stand seeing her friend in such discomfort.

 

"My b-breasts are engorged," Shy explains though gritted teeth, "P-please get me my breast pump and some washcloths. Soak the washcloths in the hottest water out of the tap and then wring them out. It'll help."

 

Rushing like one possessed, Rainbow charges down the hall, ignoring the motion of her own considerable floppers. Grabbing everything she was instructed to get, she races back.

 

Fluttershy takes one of the washcloths and places it gingerly on one of her puffy paps. Rainbow flinches as Shy hisses in pain.

 

"You okay?"

 

"I'll be fine," she grunts, "hand me the other one?"

 

The engorged girl lets the heat from the washcloths do their work for a few minutes. Then she motions for the breast pump.

 

At first it seems to go on fine, but after a while Fluttershy grows more and more frustrated.

 

"It's not working," she cries, "They're too backed up!"

 

"Now what?" Rainbow asks.

 

"I... I don't know."

 

"Well, would more heat help?" Rainbow offers.

 

"Maybe. Oh! Massaging them helps sometimes. Let me try that. If it doesn't work then I'll try a hot shower."

 

"Okay, let me know if I can help with anything."

 

"Actually, could you maybe get me some water? I'm so thirsty."

 

"Of course!" Rainbow heads to the kitchen and fills a glass with water. She blushes madly when she returns to see her friend already in the act of manipulating her taut teats.

 

"Uh... Here's your water," Dash hands Fluttershy the glass and sits down on the edge of the bed. Shy thanks her and takes a few sips. Then she returns to kneading her overtaxed mammaries.

 

Though she tries to respect her friend's privacy by looking away, Rainbow can't help but occasionally glance down at Fluttershy's efforts to relief herself. The frustrated girl rubs her paps in a circular motion. The bloated masses of womanly flesh are so tight that they barely give at all under her touch.

 

After a painful wait, Fluttershy sighs. Her nipples are finally giving up a few milky drops!

 

She hurriedly flips on the breast pump and applies it to her right breast. Even with her previous efforts though, the pump still can't find proper purchase on her stretched flesh. As the motor whirs uselessly, Fluttershy starts to cry again.

 

As she watches, Rainbow figures that the problem is with the pump itself. It simply can't handle the unusual situation that it's being presented with. Thinking about yesterday's incident in the bathroom, a desperate idea begins to form in Rainbow Dash's mind.

 

"It's not working!" Fluttershy laments, "I- I guess I'll try the shower."

 

"Wait, Flutters," Rainbow says, "This, um, might be a little weird but let me try something." She shifts around so that she's kneeling on the bed. As Fluttershy questions what her friend is doing, Rainbow brings her head down until her mouth is level with the nursing girls breasts.

 

"Rainbow, what are you doing?"

 

"Don't worry Flutters," the determined girl soothes, "If this doesn't work then I'll stop." With a halting motion she brings her mouth up to Fluttershy's engorged right teat. She purses her lips and wraps them around the feverish nipple. Before her friend can utter another protest, Rainbow Dash takes a long suck on the recalcitrant tit. Suddenly, warm, creamy liquid fills her mouth.

 

Fluttershy groans as the milk jug finally starts to give up it's load. Rainbow Dash, not really expecting milk on her first try, chokes a little on the motherly fluid. After she stops coughing she looks up at Fluttershy, silently asking for permission to continue.

 

The desperate young woman begs her friend to go on and Rainbow Dash immediately complies, returning to Shy's needy right teat and going to work.

 

What starts as a stream soon turns into a torrent as hot thick milk fills Dash's mouth with every pull. Soon she finds a rhythm that allows her to swallow the nourishing goodness between sucks.

 

After a few minutes of this, however, Rainbow starts to get a crick in her neck from her awkward position crouching in front of Fluttershy's chest. Realizing that she can't keep this up she pauses. Reassuring Shy that she isn't going anywhere she moves around to her friend's side. Leaning back so that her head rests on the nursing girl's lap, Rainbow motions that she's ready to continue. Fluttershy leans over so that her mountainous milk-makers are within easy reach of her pal's eager mouth.

 

Deciding to give the other titty some relief, Rainbow switches to Fluttershy's left side and starts nursing. The stubborn nipple refuses to give up it's bounty at first, but using her tongue to massage and caress the stiff tab, Rainbow finally coaxes out a hard won stream of milk.

 

A calm falls over the room. The only sounds are those of Rainbow Dash as she nurses and the occasional coo of relief from Fluttershy.

 

When her left breast has softened up again, Fluttershy directs Dash back to her right funbag. The suckling girl draws milk from the plump breast even as her head rests on Shy's cushy thighs. Her eyes close as she focuses solely on the sweet taste of her friend's milk. Every once in a while she takes a slightly harder pull with her mouth which causes the lactating young woman above her to moan in response.

 

She doesn't know how long her lips have been working on Fluttershy's second overburdened teat, but Rainbow becomes aware that the milky maiden is whimpering more than she was a few minute ago. And it may be her imagination but she's sure that she can hear a rustling sound.

 

Pausing for a moment she looks over a few inches and sees that Fluttershy has one of her hands down her panties and is surreptitiously rubbing her sex.

 

Two things happen at once. A startled Rainbow Dash jerks her head back and looks up at Fluttershy who, realizing that the source of her relief has stopped, pauses her self-ministrations and looks down. When their eyes meet Fluttershy goes pale.

 

"I, I, I..." she stammers, "I just felt so good, my breasts did, and I just started... Wasn't thinking... I..."

 

Seeing that her pal is on the verge of losing it, the ever loyal Rainbow sits up quickly and throws an arm around Fluttershy's shoulders.

 

"Shh, it's alright. I understand. You've been though a ton of crap and you were just trying to feel better. I'm not freaked out or anything. Heck, I'd probably do the same thing if I were in your shoes." At this point Dash is rambling and saying whatever pops into her head. "Shoot, ever since my tits started growing yesterday it's taking everything I've got not to just grope them all day long!"

 

Her words seem to get through to Fluttershy, who regains some semblance of composure, though she is still blushing red as a stop sign.

 

"I'm sorry Rainbow. I know I'm not the only one-" she notices that Dash is wearing a much bigger bra. "Oh! Did you grow again?"

 

"Uh, yeah. I woke up and there they were! I hope you don't mind, I grabbed another one of your bras."

 

"Oh, that's fine. Have they changed much?" her curiosity seems to override the shame of the past few minutes.

 

"Yeah, they're way more balanced out now, though the nipples and areolas still seem a bit to big for 'em. You wanna see?" she offers casually.

 

"You don't mind?" the timid girl asks.

 

Dash gives her a deadpan look. "Seriously? Considering all the stuff we've been doing this weekend, I don't think me taking off YOUR borrowed bra is that big of a deal." She reaches around to her back and starts unhooking the several clasps that hold the band closed.

 

Fluttershy giggles, "No I guess not." Rainbow unholsters her freshly inflated balloons and throws the brassiere to the side.

 

"Goodness!" the larger girl remarks, "They really have gotten larger. Do the feel alright? Do they hurt at all?"

 

"They feel alright I guess. Actually, I haven't really had a chance to 'get to know them' if you know what I mean. You started crying and I came over to help you and..." she trails off, not sure what else to say.

 

"Well, I think they're lovely," Fluttershy responds, "Do you mind if I..?" she makes a small motion towards Rainbow's exposed bazooms.

 

"Huh? Oh yeah, sure, knock yourself out." Dash thrusts her chest out towards her buddy. Rainbow's a little surprised that Shy is being so forward, but she DID just spend the past little while sucking on the other girl's tits. If Fluttershy want a little turnabout, then who is she to say no?

 

With a motion born of familiarity, Shy runs a soft hand around the circumference of Dash's new additions. Slipping her palm underneath one of the meaty orbs, she lifts it carefully, as though weighing it.

 

Dash starts giggling uncontrollably, "That tickles!"

 

Fluttershy grins. It's not often that she gets something over on her boisterous friend and she intends to make the most of it.

 

"It tickles, huh? What if I do... this!" Quick as a bunny rabbit, Fluttershy brings both hands up and starts rubbing the sides and bottoms of Rainbow's boobs. Gasping at the sneak attack, Dash thrashes around and leans back to get away from her tormentor. However, a suddenly confident Fluttershy presses on, switching from full on groping of the other girl's boobs to rubbing further inwards, teasing Rainbow's rosy, pointed peaks.

 

The onslaught forces Rainbow onto her back, her gelatinous tits spreading out slightly on either either side of her torso. This does nothing to limit Fluttershy's access to her nipples however and Shy's hands up their game again as they make a direct assault on the Dash's turbid nips.

 

Fluttershy is having way too much fun pinching and tweaking Rainbow Dash's fleshly tabs to notice that the gasps and giggles that she elicits with her actions are slowly turning to moans and sighs. When Fluttershy finally grows tired of her game she looks down to see a look of flushed pleasure dominating her friend's face.

 

She knows that she's crossed the line. What had been innocent fun has now turned into... something else. Catching her breath, Rainbow Dash looks up at Fluttershy in wonder. The tomboy has never felt such feelings before. She doesn't know if it's pleasure that comes only from having large, womanly mounds, or if it's something that comes of intimacy with a good friend.

 

They hold each others gaze for a moment, then Fluttershy loses her nerve and looks away. Rainbow isn't having it and reaches a hand up to steer the other young woman's face back towards hers.

 

"Hey, this is pretty crazy, huh?" she waits until Fluttershy acknowledges her, then continues, "Look, I don't know what's going on, but that felt really good and I think what I was doing to you before felt really good too, right?" Fluttershy nods slowly.

 

"What I mean is," Rainbow continues, "I want to keep going."

 

Fluttershy hangs her head, her pink hair obscuring her eyes. "I do too, but I don't know. I mean, I like boys. I didn't think... With another girl..."

 

"Hey, I know what you mean. But I don't think this is like that Flutters, not really. How do I put this? I think... I think with all the wacky stuff our bodies have been going through, that they just want some sort of release. I don't know about you but I'm about ready to explode! And you know, if this goes somewhere then I'd be cool with that. But later, if we decide that this was just a one time thing? Then I think I'd be okay with that too. What do you think?"

 

"What do I think?" Fluttershy let's her eyes roam all over the girl that she has all but pinned down to the bed beneath her. She looks at Dash's succulent mouth, which only minutes before had given her such wonderful pleasure. What does Fluttershy think?

 

Without another word she leans down and wraps her arms around the smaller form beneath her. Pressing her voluptuous body against the slimmer girl's, she takes delight in feeling her mature mounds squeezing against Rainbow's fresh ripe melons.

 

She seeks out her friend's (now her lover's) mouth, but Dash beats her to the punch and their lips lock in a clumsy but fervent kiss.

 

Trying to mimic what she's seen in movies, Rainbow opens her mouth and drags her tongue against Fluttershy's teeth. Picking up on what she's trying to do, Shy parts her jaw and feels the peculiar sensation of their tongues meeting and intertwining.

 

They make out for a little while, their bodies sharing the same space, both pairs of buxom boobs rubbing one against the other. Then Rainbow Dash takes the initiative again and reaches around to grab one of Fluttershy's bodacious butt-cheeks.

 

Feeling her feisty lover plant a hand on her rump sends a shudder of ecstasy through Fluttershy's core. She also feels a certain loosening between her thighs. She is barely conscious of the fact that her pussy is now dripping with arousal.

 

For her part, Rainbow Dash is faring little better. She has never been more turned on in her life. She's always thought that her childhood companion was beautiful, in the way that one might consider a piece of art beautiful, but lying underneath Fluttershy, looking at her amazing curves, Rainbow truly understands why guys are always drooling over her friend.

 

Of course, Dash now has some considerable assets of her own to work with. Grinning, she pauses their make-out session. She asks Shy to lean up a bit. Puzzled, her bed-mate complies.

 

Smirking, Rainbow grabs the sides of her boobs and pushes them up until her stiff nipples are lined up perfectly with Fluttershy's puckered puffies. Dash is gratified to see that her own tugs are almost as long and thick as those crowning her lover’s dangling norks.

 

Before Fluttershy can ask what Rainbow is doing, the brassy babe yells, "Nipple fight!" And starts slapping her ruby colored rods against Fluttershy's chocolate colored bon-bons.

 

At first totally confused, Fluttershy finally gets the joke and starts laughing. She even begins slinging her own heavy hangers back and forth, joining Rainbow Dash in her 'titty duel'.

 

After a few more rounds of gentle boob slapping, Fluttershy rolls over onto her back and gasps for air, still giggling at her lover's antics.

 

"Well," says Rainbow Dash, "Do you admit defeat?"

 

"Yes Rainbow," Fluttershy puffs, "I admit defeat."

 

"Ha! Then I declare myself the Supreme Champion of Nipples!"

 

Fluttershy starts laughing uncontrollably and Dash joins her.

 

When they've both calmed down, Rainbow hands down her first 'decree'.

 

"As the looser in nipple wars, you must service the winner's weapons."

 

"Huh?"

 

"I want you to suck my nipples, Fluttershy."

 

"You do? Why?"

 

"I already know what they feel like when you touch them. But I kind of want to know what it's like to have someone nursing them. I want to feel what you felt when I was nursing from you."

 

"Mmn, okay." Fluttershy agrees. Then she rolls onto her side and cups one of her own pendulous pillows. "But only if you finish what you started earlier. You got quite a lot of milk out, but the girls are still soooo full."

 

Rainbow Dash chuckles, "Sure, you got it. Now come here."

 

Scooting over on her belly, Fluttershy sticks her tongue out and hesitantly runs it across the slightly rougher skin of one of Rainbow's twin pointers.

 

Taking the whole thing in her mouth, Fluttershy sucks hard on Rainbow Dash's nipple.

 

"Aah!" the girl on the receiving end gasps. Fluttershy asks if she should continue and Rainbow nods in the affirmative.

 

Fluttershy gives both of Rainbow's blushing baps a thorough, affectionate mauling that leaves Dash a panting, wriggling mess. At some point, the athlete snakes a hand down to her needy snatch and begins to rub the soaking fabric clinging to her womanhood.

 

Fluttershy gets a wicked idea and reaches down between her lover's toned legs. Gently pushing Rainbow's busy digits aside, she takes over stroking her friend's inflamed sex even as she continues sucking on Dash's virgin teats.

 

Rainbow shrieks and moans while Fluttershy makes love to her. Emboldened, Fluttershy takes her other hand and starts to work the panties constricting her lover's crotch down over Dash's girlish hips and toned ass.

 

Fluttershy can't help but notice the marked contrast between her friend's slim body and buxom new bosom. She wonders vaguely if having large boobs will have an impact on Rainbow's sports performance. Then she remembers that she's trying to get her partner off and slips a finger into Rainbow's sultry slit.

 

The effect is immediate as Rainbow Dash howls like an alley cat. Her body thrashes hard and then freezes, her muscular back arched and trembling. The inexperienced girl shuts her eyes tight as her pelvis convulses with the best orgasm she's ever had.

 

Giving her friend time to recover from her sexual high, Fluttershy lays on her side beside her exhausted companion. She scoots up so her chest is even with Rainbow's head, then she props herself up on one elbow.

 

When the thoroughly satisfied recipient of Fluttershy's affections opens her eyes, she finds her field of vision filled with heavenly boobage.

 

Dash reaches out with her mouth and latches onto a leaking tit. Wanting to return the sublime experience that she's just had, she feels around blindly until her nimble fingers trace the silky surface of Fluttershy's lingerie clad crotch.

 

She paws at the quivering quim, trying to determine it's shape. The padded vulva is so different from her own sex. Wanting to get a better feel, Rainbow works her small hand under the waistband of Fluttershy's underwear. The lovely lower lips are puffy and hot to the touch. Running her middle finger up Shy's sodden cleft, she finally finds what she's looking for. A swollen little button of flesh almost completely hidden by a fatty fold.

 

Smiling around the milky treat resting between her lips, the mischievous young woman nudges back the hood covering Fluttershy's clit and gives it a delicate pinch between her thumb and forefinger.

 

Like Dash, Fluttershy cries out at the overwhelming stimulation to her erotic flower. Unlike her lover however, the simpering beauty tenses her whole body as though afraid that her paramour will stop the marvelous things she's doing to please her.

 

Pleased with the reaction she's elicited, Rainbow begins to alternate between laving her digits in Fluttershy's sexpot and manually stimulating her clit. It isn't long before she can hear Shy's breathing become more labored. Fluttershy begins to call out Rainbow's name, encouraging her to continue, to not stop.

 

Rainbow snickers. There isn't a thing on earth that could make her quit now. She wants to hear Fluttershy scream!

 

Her fingers are knuckle deep in Shy's slick love tunnel when the muscles surrounding them start to convulse. She knows she's close to driving her friend over the edge and tries to think of anything else that she can do to seal the deal. The answer, she realizes, is staring her in the face.

 

Clamping her teeth down on Fluttershy's weeping nipple, she nibbles on the delicate delight until, all of a sudden, her lover cries out and shudders violently.

 

At the same time, Rainbow's cheeks are filled to the max because the feminine fountain she's drinking from is spurting hot liquid all on it's own!

 

With each tremor of Fluttershy's pussy, both breasts shoot out streams of rich milk. Rainbow Dash has to turn away from the exuberant flood to keep from choking.

 

After a tremulous minute, the rush passes and in it's wake is a satisfaction unlike any Fluttershy's ever known before.

 

Basking in the afterglow of their erotic escapades, both young ladies slump down on the same fluffy pillow. Shy closes her eyes and a dreamy smile flits across her face as Dash, dear sweet Rainbow Dash, continues to partake of her immense bounty.

 

Warm, happy, and entwined in each others embrace, the satisfied pair of girls nod off into blissful sleep.

 

...

 

When she wakes up a few hours later, Rainbow Dash struggles to move. There's something heavy impeding her movement. It's still light out; probably late afternoon.

 

She tries to shift her body but the bulky mass on her chest is really making it difficult. Lazily, Dash goes through her memories to see if she can think of anything that might be responsible for the weight that's holding her down.

 

Something about milk? Her breasts growing?

 

She freezes.

 

Have her breasts grown again? Have they gotten so huge that they've made it impossible for her to get up?!

 

Dash strains her neck until she sees...

 

A snoozing Fluttershy sprawled out on top of Rainbow's body.

 

Groaning to herself, the smothered girl pushes on one of Fluttershy's shoulders. Obligingly, the still-sleeping young woman rolls off onto the mattress, freeing Dash.

 

And that's when Rainbow Dash finally gets a good look at her naked boobs.

 

"H-holy crap!"

 

The noise rouses Fluttershy. "Mmn, Rainbow? What's the matter- Oh dear!"

 

She gawks at the vision of pumped up pulchritude on display before her; the titanic titties resting on Rainbow Dash's ribcage aren't just huge, they're gigantic!

 

And they aren't just gigantic compared to Dash's previous size. Oh, no! The heaving howitzers are enormous by any standard.

 

For a moment, Rainbow can't process just how big they've grown. The wall of pale flesh totally obscures her lower half. She brings her trembling hands up to feel the unreal knockers, hoping that perhaps they're an illusion.

 

She meets firm resistance. They're real.

 

She works her seemingly minuscule arms under the marshmallowy monstrosities. Hoisting her hefty hooters higher, she can see that the her outsized nipples and areolas now seem in perfectly proportion to her enlarged funbags.

 

Still not fully believing what has happened to her chest, Rainbow tries to get up so she can view herself in Fluttershy's mirror. It proves tricky however as her balance has altered significantly.

 

The athletic girl isn't in any danger of losing her balance or falling over, but the way her chest-rockets lurch from side to side in reaction to the simplest movements is distracting at best.

 

With Fluttershy's help she finally makes it to her feet. Hugging her boobs to her torso with both arms, Rainbow Dash makes her way over to the full length mirror.

 

She lets go of her titties and they jiggle like mad as they drop several inches. It's as though they are two giant sacks filled to bursting with wobbly pudding. When they finally calm down, Dash gets to see just what her breasts have become.

 

The fat boobs start high on Rainbow's chest. They're round and full on both top and bottom. Rather than pointing slightly up, like before, her nipples now point strait out. Her crimson areolas have completely lost their domed shape and now sit flush with the rest of her breasts.

 

Dash's lean torso is, quite simply, overwhelmed by it's new burden. Turning around, she lifts her arms above her head and looks behind her. A good portion of each breast is clearly visible, peeking out on either side of her back.

 

Turning to the side, the top-heavy young woman views her boobs in profile and it's easy to see the biggest difference between her bosom and Fluttershy's: their shape.

 

While there is a bit of a conical form to Fluttershy's tits, they're mostly very round. On the other hand, Rainbow Dash's gazongas are classic 'torpedo tits'. Quite a bit longer than they are wide, they thrust off of her chest at a very perky angle, especially considering their fantastic mass and proportions.

 

"Well, at least they aren't drooping, but how am I going to do anything with them?" she whines.

 

Fluttershy joins Dash in front of the mirror and examines her friend. With both their breasts bare and on display, it soon becomes obvious that, though both sets look quite different, their overall size is pretty similar.

 

"Hmn..." Fluttershy muses, "Wait here a minute."

 

She rummages around in her dresser until she finds what she's looking for.

 

"Here," Fluttershy hands Rainbow a white bra, "The band on that will probably be loose since you're, um, skinnier than I am. But I think the cups should fit you. I'll go get some safety pins and we can cinch up the body band."

 

As Fluttershy goes to leave Rainbow asks, "Is this another one of your old bras?"

 

"Um, no. It's one that I wear right now. I'll, uh, be right back."

 

Rainbow Dash can't help but freak out a little. Has she gotten THAT big? She searches the spacious bra for a tag. She HAS to know what size it is.

 

Her mouth goes dry when she finds the tag and reads '36 J'.

 

Not that she should be surprised. Each heavily stitched cup is the size of a helmet. And this is something that's going to fit her? She wants to laugh at the absurdity of it all, but she fears that she can't. At least, not until she's tried the darn thing on.

 

Trying to remember how Fluttershy puts her bras on, Rainbow puts it on backwards and does up the band first with its multitude of hooks. Then she rotates it around her torso until the cups are in front and the hooks are in back. Leaning forward, she slips her arms through the shoulder straps and lowers her jubblies into the lacy cups. Making sure the shoulder straps are secure and her boobs are seated, she stands up strait.

 

As Fluttershy suspected, the 36 inch band is rather loose.

 

The cups, however, fit just fine.

 

Rainbow may not be the most knowledgeable person when it comes to lingerie, but she does know that going from a DD-cup to a J-cup is a vast increase. Why such a huge jump this time when her gains the previous two times where far less?

 

The only thing that makes sense is that she must have consumed a way more milk during their lovemaking session. Given how full Fluttershy was and how long Rainbow nursed, it's the most reasonable explanation.

 

"Alright, here we are," chirps Fluttershy as she returns with the safety pins.

 

She temporarily modifies the bra Dash is wearing, and they both get dressed. As the eventful day winds to a close they head downstairs to get supper.

 

Throughout dinner, Dash peppers her friend with questions about being stacked. What kind of clothes does she need? Do her boobs ever hurt her? Is there anything she needs to watch out for?

 

Fluttershy does her best to answer. Really though, she's quite excited to have a friend who is busty like her. She's always felt a bit isolated by her size and having a friend that can understand what it's like being very voluptuous is a dream come true

 

When the food is finished, Rainbow Dash confesses that she's both scared and excited. The idea that she has to go to school on Monday with tits the size of volley balls is not one she's looking forward too. Plus she has to explain her new curves to her mother. Super awkward!

 

But, on the flip-side, she's got tits! And not just run-of-the-mill tits either. She's got boobs that would make any porn star jealous, except hers are real. Rainbow has no idea what this means for her future sports career but she decides that, since she can't do anything about her new sweater puppies, she may as well roll with it.

 

Perhaps now the boys will drool over her as well as Fluttershy!

 

As they prepare for bed, Rainbow asks her hostess if she's going to take care of her milk. Fluttershy explains that she usually breaks out the breast pump when her teats get full.

 

"It's weird," she says, "I don't feel any buildup at all. If I didn't know better I'd say I've stopped producing milk."

 

Rainbow giggles, "Well then, I guess I drained you pretty good!"

 

"I guess so." Fluttershy chuckles, "Good night."

 

"Good night."

 

...

 

The next morning Fluttershy wakes up very refreshed. Her breasts are experiencing none of the tell-tale signs of her making milk. Perhaps she really has stopped producing!

 

Eager to share her good fortune she wakes up Rainbow Dash.

 

However, when the newly buxom Dash throws off her own covers they both see a pair of familiar wet patches staining Rainbow's sleep shirt.

 

"Wha- what the heck!" Rainbow yells.

 

...

 

Fluttershy has Rainbow take off her damp top. Underneath, Dash's twin missiles stand proudly at attention. When she had gone to bed, her breasts had been soft and supple. The slightest movement sent tremors across the gelatinous globes.

 

Now both her tits are warm to the touch and tense. When she shakes her torso experimentally from side to side, instead of rippling and shimmying like barely set jello, the stuffed boobs bounce haltingly as a result of their unnatural firmness.

 

Fluttershy peers at her friend's puffed up protuberances. Dash's nipples aren't visibly longer but they are definitely thicker. The rosy flesh surrounding them is an angry scarlet.

 

Most telling of all is the dried trickle of milk that adorns the bottom of Rainbow Dash's jugs.

 

Fluttershy asks her pal how she's feeling and Rainbow responds that her chest is a little sore. It kind of feel like she has a full bladder, she elaborates, only in her boobs.

 

Fluttershy gives a knowing nod and tells Dash to follow her to the bathroom. It's time to give her guest an in depth lesson in all things lactation.

 

Dash sits on the edge of the tub, clad only in her sky-blue panties, as Shy explains all she knows about expressing milk.

 

"So if you go too long, the milk will get backed up and your boobs get engorged?"

 

"Yes, and heat can help with that. Now, let's have you try the breast pump." Fluttershy hand the other young woman the portable device.

 

Rainbow Dash goes through the steps that her friend has prescribed. She gingerly kneads the undersides of her sore lobes, pushing up into the tender flesh with her open palms. Then she runs her hands from the base of her breasts to their tips, coaxing her paps into giving up their luscious load.

 

When she finally sees a trickle ooze out of one of her ruby nips, she turns on the pump and applies the clear plastic to her right teat.

 

Dash isn't sure what to expect, perhaps that the mechanical pump will feel like Fluttershy's mouth when it was suckling her erotic pointers the previous evening.

 

Instead, the cycling vacuum of the pump feels like nothing more than a cold plastic suction cup pulling on her teat.

 

When she hears a slurping sound coming from below, Dash looks down to see that white liquid is churning through the clear plastic tubing. Her breasts have officially reached let-down and Rainbow Dash has unofficially reached milk-cow status.

 

As the pump continues to drain Dash's breast, Fluttershy asks how she feels.

 

"Fine, I guess," she responds, "But, you know, this doesn't feel near as good as when YOU were sucking on 'em last night."

 

Fluttershy giggles, "I can imagine. But I'm afraid if I drank your milk then I might get even bigger! So, thank you, but I think I'll pass."

 

Rainbow jokingly bemoans her friend's refusal, even as she imagines Fluttershy's already impressive bosom expanded to double or even triple its original size. In her mind's eye there stands the voluptuous, pink haired girl with tits that are so big they hang down to her waist! Not only that, but they are so unbelievably full and shapely that each one sticks out from her torso by several feet.

 

Snapping out of her daydream, Rainbow asks Fluttershy why she thinks this is happening. Why has she started started giving milk, even as Fluttershy has dried up?

 

"I've been thinking about that," remarks Fluttershy, "You know, I'm pretty sure my situation was related to Twilight and all the magic that went on when we fought Sunset Shimmer. If you think about it that way, then it makes sense that I've passed my ability to make milk on to you."

 

"What do you mean?"

 

"Well, in all the fairy tales, when someone gets a magical gift they have to use it to help others. If they don't then it usually turns against them. And sometimes, by the end of the story, when they've fixed their problem the hero or heroine passes their gift on to someone else who needs it."

 

"Whoa, whoa, whoa! You're saying that these tits are what, magical? What does that make you, my fairy godmother? That's a good one. Oh, oh! Your magical words can be 'Bibbity-Bobbity-Boob!' Ha ha ha!"

 

Fluttershy sniffs haughtily and points to her friend's gushing gourds, "Laugh all you want, but how else do you explain your breasts growing so big and fast and giving milk?"

 

"Yeah, I guess you're right. Man, this is taking forever! Can't this pump go any faster?"

 

"If it sucked any harder it would probably hurt after a while."

 

"I guess. Argh! I still have my other boob to do too! And you had to do this twice a day?"

 

"Mmm-hmn. Sometimes I'd do it three times a day."

 

"I thought that if you stopped milking that eventually your breasts would dry up. I know it might hurt for a bit, but couldn't I trick mine into stopping by just not pumping them for a few days?"

 

"Um, I wouldn't do that if I were you. I tried what you just said. My breasts got so sore that I was crying. It took me hours to get them flowing again. And," Fluttershy turns away and blushes I think doing that actually made them... bigger."

 

Dash tries to imagine herself with even bigger hooters and shudders. She's probably going to need three or four sports bras to run as it is!

 

"So I guess I'll keep milking them," she sighs.

 

"Oh, it's not that bad. I usually just let my mind wander when I'm nursing."

 

Rainbow just grunts in response. Her first breast stops giving up liquid so she switches to the other one. After a few minutes her other teat is drained and the bottle is full with her first batch of breast milk.

 

Rainbow Dash whistles softly as she looks at the pint sized bottle.

 

"Holy cow!" she shakes her head, "What do I even do with all this stuff?"

 

"Um, unless you want to give someone bigger breast, I'd throw it down the sink." Fluttershy offers.

 

"Give someone bigger breasts, huh?" Dash rubs her stretched nipples, trying to work out the tingling left from the breast pump.

 

"Say, Flutters, have you ever, you know, tried some of your own?" she asks, shaking the bottle full of maidenly milk.

 

Fluttershy squeals and quickly hides her face behind her hair. Rainbow laughs.

 

"I'll take that as a yes?" Fluttershy meekly nods her up and down. "And it didn't make you, uh, larger?"

 

"I don't think so."

 

"Hmn," Rainbow gives her fluid a curious sniff, then takes a sip.

 

She smacks her lips, "Not bad!" she declares, "Not as good as yours, Flutters, but not bad." She dumps the rest in the sink.

 

Back in the bedroom, Rainbow Dash and Fluttershy get dressed. Both are very quiet, one because it's her nature and the other because she is deep in thought.

 

As Rainbow Dash slips into one of Fluttershy's nursing bras she pipes up, "So Flutters, you think this is a gift, huh?" She cups her enhanced assets.

 

"Maybe? I don't know, I like mine. They make me feel pretty."

 

"And how long have you making milk? Er, before last night, I mean?"

 

"Since just after Twilight's first visit."

 

"So I'll probably keep going until I give my 'gift' away to somebody else directly, huh?"

 

"Goodness Rainbow, I suppose so."

 

"So how about I REALLY share my gift," Rainbow gives her jugs a good jiggle and grins lecherously.

 

"Rainbow Dash, what are you going to do?"

 

The brash girl puts her arm around her shy friend.

 

"It's not what I'm going to do. It's what WE are going to do. You still help out in school cafeteria right?"

 

...

 

It has been a week since the sleepover at Fluttershy's. There had been an uproar at school the following Monday when Rainbow Dash, the star athlete of Canterlot High, had walked through the front door with bowling ball sized boobs filling out her track suit.

 

At first everyone assumed it was a joke. Principal Celestia had even gone so far as to call the top-heavy student into her office, intent on calling her out for her tom-foolery. All it had taken was Dash unzipping her wind-breaker and showing off six inches of cleavage for Celestia to immediately apologize.

 

Though she had gotten off Scott-free, the worried administrator did send Rainbow to the school nurse to get checked out. Nurse Redheart had, of course, found nothing wrong with the girl's mammary glands. They were simply big. That was all. Fortunately Dash had emptied her tits right before school. She didn't want to have to explain that little quirk of her physiology!"

 

The rest of the school hadn't accepted Rainbow's incredible changes quite so readily. One boy had even 'accidentally' bumped into her chest, open palms first, to see if she was stuffing her bra!

 

It wasn't until after a few showers in the locker room, when enough girls got to see a naked Dash in all her glory, that the rumors of her faking it were quashed.

 

After that, all she had to deal with were the same things Fluttershy had struggled with for years: rumors that she was easy, catcalls from most of the boys, and awkward stares from everyone else.

 

Fortunately, she had a plan to draw attention away from herself and Fluttershy.

 

It's Friday and Rainbow Dash is hunting for a certain purple-haired fashionista. Having had a week to get used to her new body (and shop for some heavy-duty sports-bras), Dash zips around campus at something close to her usual speed, pre-magical boobs.

 

"Hey, Rarity!" Rainbow Dash cheers as she sits down on the bench in the courtyard. Rarity is eating by herself today which gives Rainbow a chance to set her plan into motion.

 

"Oh, hello darling." Rarity nods to her friend, "Come to join me? Well, have a seat. You know, I don't mean to be rude, but I don't think I'll ever get used to you having, uh..."

 

"Boobs?" Rainbow offers.

 

Rarity chokes, "Ahem! What I meant was, I'll never get used to you having such an... exuberant bust-line."

 

"Aww, are you jealous?"

 

"Certainly not! I am quite happy with how I look."

 

"But you wouldn't mind a little more on top, would you?" Dash leers.

 

"Well..." the fashion major looks down at her own modest front, "I suppose a little more wouldn't be a bad thing. But it doesn't matter; wishing doesn't make your breasts grow."

 

"Hah! I knew it! Aw, don't worry, Rares. I'll bet you still have some growing left to do. Say, I'm pretty full and Fluttershy made me all this chocolate pudding in home ec. I've had a bunch and she gave me two batches. You want some?"

 

"Why thank you dear!" Rarity takes the plastic container, "I've never been one to pass up anything chocolate."

 

"I know," Rainbow smirks.

 

"What was that, darling?"

 

"Uh, I said, 'I know' like 'I know, who can resist chocolate pudding' right?"

 

"True, true... Mmn! This is delicious! Give my compliments to Fluttershy."

 

"I sure will. I helped her with it, you know."

 

"Really?"

 

"Yeah," Rainbow Dash grins like the cat that swallowed the canary, "I got her some of the ingredients."

 

...

 

The following Monday, Rainbow Dash finds a note in her locker. It's from Rarity and reads:

 

'Dear Rainbow Dash,

 

Please come and see me in the textiles room during your free period this morning.

 

Sincerely,

Rarity'

 

This is perfect, Rainbow thinks. She's been trying to figure out when she can see Rarity and the results of her 'special' chocolate pudding. Now she doesn't have to wait!

 

After first period, Dash makes her way to the textiles room where home-ec and clothing design hold classes. There doesn't appear to be a class using the room at the moment so she walks in. Inside, she sees Rarity sitting at one of the tables in the back and sitting beside her is...

 

Fluttershy?

 

"Please come in Rainbow Dash," Rarity says in a low voice, "And close the door, won't you?"

 

The puzzled girl does as she's asked and walks over to her friends. She's disappointed to see that Rarity has on a loose fitting silk blouse that, combined with the fact that she's sitting leaning forward with her arm resting on the table, conceals any of the fashion maven's curves.

 

"You know," Rarity begins suddenly, "It's the funniest thing. This last Saturday I woke up and found that something strange had happened to me. It was quite a shock, I assure you." Dash feels her mouth go dry.

 

"It was so shocking that I felt the need to share it with someone. I couldn't go to my mother, she would have become hysterical. So I called my good friend Fluttershy. I thought that if anyone could commiserate with my sudden 'situation' she could. So imagine my surprise when, instead of surprise at what she saw, my dear friend looked nervous and..." Rarity looks over at Fluttershy who is staring at the floor, "Guilty."

 

"Ah, Flutters," Rainbow sighs, "You didn't-"

 

"Ah, ah, ah! Don't blame this on her. I know she was just your accomplice. She told me what was in that pudding and what has happened to you both. So now I will ask you directly, Rainbow Dash..." the other girls in the room stare as Rarity suddenly begins unbuttoning her blouse.

 

"Why in the world did you feel the need to give me BIGGER BREASTS!" she shrieks as she pulls her top open.

 

Underneath the silk shirt, Rarity has on a lacy white bra of substantial proportions. Even though the foundation garment gives excellent coverage, it can't quite obscure the line of Rarity's fresh cleavage. Looking closely, Rainbow swears she can make out faint pink tips through the sheer material of the bra.

 

"Rainbow Dash! Are you paying attention? What do you have to say for yourself?"

 

Thrown off balance Rarity's interrogation and the vision of her satin-swathed breasts, the guilty party says the first thing that comes to mind.

 

"What are those, D-cups?"

 

"Arrgh!" Rarity raves.

 

"Okay, okay. Sheesh! Look, Rares. I have a gift. Why wouldn't I want to share the big boob love?"

 

"And you thought I'd be a good first test subject?"

 

"Well, yeah." Rainbow admits. Before Rarity can rebuke her, Rainbow continues, "I know you've always wanted bigger boobs. No, don't give me that, I know you do. I've seen how you look at all the girls with big racks around here. I just thought that if you got bigger boobs you'd be happy."

 

"By why sneak around? Why not tell me what you wanted to do directly?"

 

"Eh, it would have taken too long."

 

"What!"

 

"Geez, Rarity, stop yelling. Look, first I would've had to convince you I wasn't crazy. Then I would've had to convince you to eat the pudding. Would you have, even if it could have given you bigger boobs?"

 

"Well..." Rarity looks away.

 

"Exactly! Plus, if someone hadn't spilled the beans," Dash looks at her timid cohort, "You would have thought it was just a growth spurt, that you got bigger on your own. I don't want a lot of people to know about this, you know."

 

Rarity stares hard at her friend. Finally, she sighs.

 

"I appreciate your reasoning Rainbow Dash and it's true, I suppose I always HAVE been a little envious of those around me who were a bit more buxom. But your methods are no good."

 

"What do you mean?"

 

"First of all, no girl who goes from an A-cup to a D-cup overnight is going to think that's a normal growth spurt."

 

"Hah!" Dash barks, "D-cups! Called it."

 

"Oh for- Listen to me you scoundrel! It took everything I had to hide this bosom from my mother. If she had seen that I've grown bigger than her in less than a day she would have had a heart attack. As it is I'm going to have to bind these beauties and let them out little by little so that everyone thinks I'm growing naturally."

 

Rainbow Dash looks thoughtful as she considers what her friend has just said, "Sooo, what you're saying is, I should have given you smaller doses and then you wouldn't have caught on?"

 

Fluttershy interjects, "Oh Rainbow, I don't think that's what Rarity is saying at all."

 

"Actually," their purple-haired friend corrects, "That's exactly what I'm saying."

 

Both of the other girls looked confused, "Huh?"

 

"Don't mistake me, either of you. I'm still mad at you for giving me these breasts. These wonderful, magnificent, perky breasts..." she trails off for a moment, then shakes her head and regains focus, "But I'm also a fashion designer. My life's work is to give women everywhere what they want," Rarity cups her hands under her brassiere and pushes it up a few inches, "And what women want right now is an exaggerated bust-line."

 

"Soooo, does this mean you're not going to turn us in to the principal?" Rainbow asks.

 

"Sigh. I suppose not." Dash does a small fist pump, "But! You WILL consult with me before you 'bless' anyone else with your gift. And you will do so in a way that doesn't have them wondering if they've contracted some sort of odd disease."

 

"Sure, sure." Rainbow nods her head, "Anything you say. But I don't want YOU telling anyone else about this either."

 

"Hm. Very well. Now, what are your plans going forward?"

 

Fluttershy and Rainbow Dash both look lost. Rarity smirks.

 

"No idea, eh? Just winging it? Well then, might I make a suggestion?"

 

...

 

"Hey Applejack, Wait up!"

 

"Hey Rainbow," the cowgirl waves, "Are you sure you're up to this?"

 

"Of course I am! Why wouldn't I be?"

 

Applejack looks uncomfortable, "Well, I was just thinkin' ya might not wanna go runnin' in yer, uhh, condition."

 

Rainbow Dash rolls her eyes, "Oh good grief, not you too! I got boobs, AJ, I didn't break my legs! Trust me, it'd take a lot more that these," she pats her upholstered front, "To throw me off my running schedule. No come on!"

 

The blond shakes her head, "Alright. Off we go."

 

Both young women start off down the greenbelt path of the city park, Applejack in her cargo shorts and t-shirt, Rainbow Dash in her running spats and over-sized tank-top. Applejack can see the heavy straps of her companion's bra through the gaps around Dash's shoulders. In fact, she can see several.

 

"Hey, are you wearin' two bras?"

 

"No."

 

"Oh, well it looks like-"

 

"I'm wearing three."

 

Applejack chokes on what she is planning to say next.

 

"Yeah," the bustier of the two continues, "Rarity helped me pick 'em out. I think three is just the right number. See how they aren't bouncing? Well, not much anyway. The only problem is that they get kind of sweaty."

 

"Yeah, no joke. Rainbow, what happened to you? You were flat as a tabletop two week ago and then Wham! You got watermelons growin' outa yer chest."

 

"It's like I told everybody, they've been growing for a little while. I was sorta strapping 'em down but it just started hurting to bad. So I went to buy a bra and the saleslady freaks. Tells me I'm a K-cup, which is weird because I thought my boobs were the same size as Fluttershy's but I guess my ribcage is smaller? I dunno."

 

"Rainbow."

 

"Yeah?"

 

"That's the biggest load of horse apples I ever heard in my life. I don't care how tight you strapped 'em down I would have noticed. Plus all yer team mates on the soccer team would have seen you in the locker room. Now what's really going on?"

 

Both girls continue on through the park in silence for a little while.

 

Then Dash starts laughing.

 

"Ha ha hah! Rarity told me you wouldn't buy it. Ah, AJ you're too good. Alright, I'll tell you the truth. My tits grew this big during one weekend. Oh, and I'm giving milk."

 

"Whu? Y-you serious?"

 

"As a heart attack. But you want to hear the weirdest thing?"

 

"There's more?"

 

"Heh heh, yep! You ready for this? My breast milk can give other girls bigger boobs."

 

Applejack stumbles and almost trips. Her running mate comes to a halt as the farm girl rounds angrily on her friend.

 

"What did you say?!"

 

"My breast milk makes tits grow."

 

"Bullshit!"

 

"Whoa-ho, AJ! You kiss Granny Smith with that mouth? I'm not lying to you. You can ask Rarity. She's filling out her dresses a little better these days thanks to me."

 

Applejack glares at her companion. Dash holds her gaze as though daring the country girl to call her a liar.

 

Finally, "I... Yer not jokin'. But why are you tellin' me all this?"

 

"Because I knew you'd find out eventually. Aaaand, I thought you might want some of what I'm offering." Rainbow waggles her eyebrows suggestively.

 

"You think..? Yer crazy!" Applejack starts moving again. Her friend follows.

 

"Hey, I didn't say you had to get as big as me. But think about it. You could totally go up a few cup sizes if you wanted."

 

"And why would I want to do that?"

 

"Because Rarity told me that you might be interested in getting bigger boobs."

 

Applejack sputters and grinds to a halt again. The bright blush on her face isn't from physical exertion.

 

"Rarity that rat! She told you about the pads?"

 

"No," the other girl is confused, "What pads?"

 

"The..." Applejack looks down, shamefaced. "You gotta swear you won't tell anyone else."

 

"Sure, no prob."

 

"I mean it Rainbow Dash. Swear it. A Pinkie Pie Swear!"

 

"Geez, alright!"

 

The stacked girl goes through the motions of the peculiar oath invented my their friend.

 

"Okay, there you go. Now, pads?" Rainbow inquires impatiently.

 

"The truth is... This is so embarrassin'. The truth is that I'm as flat as you are. Were. As flat as you were."

 

Dash looks down at her friend's average sized breasts. It takes her a moment, but finally the truth dawns on her.

 

"So you're telling me you've been stuffing all this time?"

 

Applejack looks away and nods her head.

 

"Aw AJ, why?"

 

"I just..." the blonde squeezes her eyes shut. A look of self-loathing mars her features. "It was Apple Bloom. A few years back she got bigger'n me."

 

"Uh, I saw her last week," Rainbow counters, "Pretty sure she's still shorter than you."

 

"No you dummy, her breasts! She's got bigger breasts than me!" Now there are tears in Applejack's eyes.

 

Taken aback by the other girl's outburst, Rainbow softens her tone.

 

"She does? I mean, yeah, she does have a chest I guess. Not that big though."

 

"Still bigger'n mine. You know how embarrassin' it is when your kid sister comes to you and tells you she needs a trainin' bra and you don't because you got nothin' to put in 'em?"

 

"Yikes."

 

"Yeah," Applejack retorts, "That's when I started stuffin'. After I got a bra that is. Then last year, Apple Bloom busts outa that trainin' bra and we have to get her a real one. Not a big one, an A-cup. But it was the same cup size as the one I was wearin' at the time, even with the pads."

 

"So you upped the size of your pads." Rainbow finishes for her.

 

The farm girl nods.

 

"Our mama was real pretty. She had bright red hair and a really great figure. Heh heh. My pa had to beat his rivals off with a stick! Anyway, I think my sis is growin' up to be just like her. Me on the other hand..." she sighs.

 

The athlete has no idea what to say. She's the last person to comfort someone else, especially on something like this.

 

But she does have on thing she can offer.

 

"Applejack. Hey, look at me." When she has the sniffling young woman's attention she continues, "I don't know what to tell you but you're pretty hot just the way you are."

 

"You're just sayin' that."

 

"Right, sure I am. And I guess I made up all those guys I've heard who think you have the best ass in the whole school. That makes me totally jealous of by the way," she pats her own toned booty, "Anyways, you're hot. You need to accept it and move on."

 

"But..." Applejack looks like she's ready to argue. A look her friend is more than familiar with.

 

"Ah-tut-tut-tut! Nope! Hot. Best ass in school. Deal with it."

 

The cow-girl looks at Dash and opens her mouth but doesn't say anything. Finally she hangs her head and gives a dry chuckle.

 

"Alright, Rainbow. You win."

 

"Awesome!" the brash young woman puts a hand on her friend's shoulder, "Now how much bigger do want to get?"

 

Applejack looks at her companion and quirks and eyebrow, "Really? You just gave me this big ole speech about acceptin' myself for who I am and now you want me to change somethin' about myself?"

 

"Hey, I was just saying you don't have anything to worry about. You're hot with or without boobs," the top-heavy temptress leans in and croons, "But if you can get bigger boobs just like that, then why wouldn't you?"

 

"I-I..." Applejack looks totally lost.

 

Taking pity on her friend, Dash waves and says, "Come on let's head back to my house and you can make up your mind there.

 

They both head back the way they came and then onto the side street leading to Dash's house. When they arrive, Rainbow Dash guides Applejack to the kitchen and has her take a seat. The busty young woman walks over to the refrigerator and retrieves a clear bottle full of milk. Rumaging around in the freezer and cabinets, she pulls out some other ingredients, throwing them into a blender. Finally, she measures out a half cup of milk and dumps it in as well.

 

"What are you doin' over there?" the curious cowgirl asks.

 

"Mixing you up a big titty milkshake."

 

Dash throws some ice in the carafe and starts the blender. A minute later, a tall frosty glass sits in front of the reluctant Applejack.

 

"There you go! You drink that and you won't have to use pads anymore."

 

The blonde does not look convinced.

 

"This won't make me get too big will it? I don't wanna blow up like you."

 

Dash puts a hand on her hip and deadpans, "Gee, thanks. Nah, this has just enough 'special ingredient' to only make you a little bigger. Probably one or two cup sizes."

 

"Probably?"

 

"Hey this isn't science, it's some kind of crazy boobie magic. I only put in a little bit of milk. You can have more later if you want. Now are you going to drink it or are you stare it to death?"

 

"Hmm. Alright, sure. Why not?"

 

The flat farmer grabs the glass and takes a sip, smacks her lips, smiles, and chugs the rest.

 

"Pwah! I'll say this for ya, you make a tasty milkshake, Rainbow."

 

Grinning deviously, the chesty girl looks down at her padded torso.

 

"I sure do. In more ways than one."

 

Applejack goes green around the gills, "Oh, sweet mercy! I forgot it had your breast milk in it. Hurp!"

 

Dash slams her palms down on the table, "Don't you dare hork that up! Alright, well that's it. Now tomorrow morning you should see some results. And remember," she singsongs, "You can always come back later for more!"

 

...

 

Early the next morning after a run, Rainbow Dash is headed to the locker room for a quick shower. A beaming Applejack is waiting for her at the entrance. Glad to see her pal in a good mood, Rainbow waves.

 

"Hey, girl! How's it going?"

 

"Oh, it's goin' just fine Rainbow. I wanted to let you know..." the farmer gulps and looks around nervously. Seeing that the gym is deserted, she continues, "It worked, it really worked!"

 

"Sweet! Lemme see."

 

"Now? Here?" Applejack blanches.

 

"Nah, in the locker room. Come on."

 

Inside the changing station beside the showers the more well-endowed of the two begins to strip off her clothes.

 

"What are you doin'?" asks the flummoxed farm girl.

 

"Duh! I got to take a shower. Now take of your top, I want to see 'em."

 

Grumbling all the while, Applejack undoes her flannel shirt and peels if off revealing a plain white bra. While average in size, it is fully packed with girl-flesh.

 

Rainbow, who by this time is standing around in her underwear, starts the laborious process of unhooking her huge bra. She looks at her companion expectantly.

 

"Don't be shy, AJ."

 

Trying to tell herself that Dash is simply curious, she undoes her brassiere and slides it off. When she looks up, her busty patron is standing in the buff and Applejack looks on in wonder at her unreal form. Rainbow still has the same slim build as before, although her hips might be a bit wider than she remembers. But adorning her pal's toned upper half are breasts that look bigger than her head!

 

Applejack can't tear her eyes away as the chesty vision that is Rainbow Dash approaches. Both tits thrust from the girl's torso as though she's wearing an invisible support bra, yet they don't have the artificial shape and lift of boobs with implants. The upper and lower curves hang proudly, if heavily, and heave to and fro with each step their mistress takes. The nipples that cap Dash's fantastic floats are bright red, a stark contrast to the fair skin surrounding them.

 

She is so taken by the sight of those magnificent mammaries that she doesn't notice when Dash addresses her.

 

"...Hey, you awake?"

 

"Huh? Oh, sorry." the distracted young woman apologizes, "What was that?"

 

"I said, you've got nice boobs." Dash's compliment is honest and direct, a fact that increases Applejack's embarrassment for some reason.

 

The blonde girl's breasts are of moderate size, easily cuppable in her slim hands. Their gently rounded shapes rise off her chest like twin hills. On top of those hills are small dusky cones, her areolas, which stand out proudly from her perky tits and hide her small nipples.

 

Rainbow examines them as one might an interesting sculpture.

 

"Yep, they look good. What are you up to size-wise?"

 

Applejack glances back down at Dash's boobs, "An A-cup. But it's a little tight."

 

"Yeah, I saw that," Dash chuckles, "Wanna bump 'em up a bit? Make 'em a full B or C?"

 

"Uh, sure. Wait, what?" the confused girl tears her eyes away from the others trembling ta-tas. She can't help looking at them; their just so... big!

 

Guessing why her friend is distracted, Dash smiles innocently and holds one of her boobs up with both hands and points it towards Applejack.

 

"They ARE pretty amazing, aren't they? You want to feel them?"

 

"What? No!"

 

"Ah, come on. It's not weird or anything. I just thought you might like to see what really big boobs are like. Y'know, in case you wanted to make yours bigger later," she proffers her breast again, "It's fine, give it a feel."

 

Applejack hems and haws. When Rainbow starts tapping her foot impatiently, the squeamish young woman finally acts. Her outstretched hand inches forward until, finally, it makes contact with soft tit flesh...

 

And then jerks back like it's touched a live circuit. Dash looks at her as though to say, "Really?". Sheepishly, Applejack reaches out to the plush boob and this time begins to feel around. The skin is soft and the mass underneath feels firm to the touch, yet gives easily when she pushes into it.

 

It's so weird and yet so fascinating!

 

The enraptured girl is so engrossed in her explorations that she doesn't notice Dash snaking her own hand up towards the dainty apples sitting on her chest. She barely even registers the first tentative caress across her burgeoning bumps.

 

When Dash gives her companion's nipple a light pinch, though, it definitely gets Applejack’s attention.

 

"Whoa! Hey now!" The farm girl jumps back at swats at Dash's groping hand, "Let's not go crazy there."

 

Rainbow smiles apologetically, "Sorry AJ, guess I should have asked first. It's just, there were right there and you know what they say, 'When in Rome'."

 

Applejack starts to put her bra back on, "I'm pretty sure that's not what that means."

 

"Really? Huh."

 

Ignoring her disappointment at not being able to further grope her friend's cute little boobs, Dash instead restates her offer to make Applejack's breasts bigger.

 

To her mild surprise Applejack agrees.

 

"You know I didn't think I'd want 'em any bigger but now the more I look at 'em the more I think a little more would look pretty nice."

 

"Sweet! I, uh, already drained the 'girls' this morning. I bring you another shake tomorrow. Same as the one I made yesterday okay?"

 

"Mmm, make it a little bit more. I think it's time become the 'big' sister again."

 

"Ha ha! You got it! And you think you might go bigger later?"

 

"Yeah," the country gives Dash a look of pure delight, "I'm definitely going to go bigger."

 

...

 

The next afternoon, the Canterlot High varsity girls soccer team is hustling up and down the field under the direction of their captain, Rainbow Dash.

 

Watching the older girls go through their drills, Scootaloo tries to absorb what she can of their techniques from sidelines. Finally, Dash blows her whistle and calls a halt.

 

"Alright! Good job everyone. Let's take a break. Hey Scoots, what's up?"

 

"Hey, Rainbow Dash! We just got done with our practice and I thought I'd come see what you guys were up to."

 

The varsity girl smiles down at her number one fan.

 

"Cool. We're just taking a water break."

 

"Yeah, I'm kind of thirsty myself. Should have stopped for water but I came strait over instead."

 

Dash frowns, "Well, get something to drink. We've got plenty here."

 

"Thanks Rainbow." Scootaloo smiles.

 

Dash returns the smile, her annoyance towards the younger athlete for ignoring basic hydration forgotten. When Rainbow had revealed her new breasts to the world, Scootaloo had taken it especially hard. She thought it was a trick at first, but soon realized that her idol really had somehow become the bustiest girl around (except maybe for Fluttershy). She didn't know why but she had felt betrayed. Top athletes didn't have big boobs! How would her hero be able to compete now?

 

Except that the hard charging Dash HAD been able to compete. There was a definite difference to her play style now, Scootaloo noted, but her mentor was still able to kick butt just like before.

 

And STILL she had felt upset. The true reason why finally hit her one day a week later while she had been hanging out with her two very best friends, Sweetie Belle and Apple Bloom. The latter of the two was wearing a tight t-shirt that showed off the outline of her bra and left no question that she was on her way to getting a decent pair of breasts. Both Sweetie and Scootaloo loved their friend dearly, but they had admitted to each other in private that her development made them both a little jealous.

 

Kind of like how she now felt towards Rainbow Dash.

 

Having figured out the source of her irritation helped. It also helped that Dash had figured out that something was wrong and had gone out of her way to spend time with her honorary little sister. Somewhere along the way Scootaloo found that she no longer felt resentment towards the older girl. So what if she had gotten big boobs? She was still the same old Dash.

 

Although, Scootaloo thinks as she looks at her 'big sis', it would be neat if she could get a little more grown up too.

 

"Hey Cap!" one of the varsity girls calls, "Do you know where the first aid kit is? We got a cut over here."

 

Dash groans and heads over to help her team mates, "I'll be back."

 

Scootaloo looks around for something to quench her thirst and sees a cooler bag next to were Rainbow was sitting.

 

"There we go!" she chirps as she digs into the bag.

 

When Dash gets back to the bench she feels the color drain from her face. Scootaloo is lowering a bottle from her lips. The same bottle containing Applejack's special milkshake that had been prepared earlier that morning.

 

Dash immediately barks, "Scoots, don't drink that!"

 

Surprised, Scootaloo almost drops the smoothie. "I-I'm sorry. You said I could drink whatever. Was I not supposed to drink this?"

 

Rainbow tries to calm down, "I meant you could have the Power-aid or the water on the... Hey!" she yells to her team mates down the field, "Where's the drinks?"

 

"I shoved them under the equipment by the bench so they'd stay cold!" one of the other girls calls back.

 

"Ahh!" Dash shakes her head in frustration.

 

"I'm really sorry, Rainbow Dash. I didn't know." Scootaloo's apologetic look makes the older girl feel even worse.

 

"No, no. It's fine." Dash reassures her, "It's totally my fault. I should have paid more attention. Seriously, don't worry about it."

 

"There's still half left, if you want it." Scootaloo offers Rainbow the bottle.

 

"Thanks," she takes the proffered container, "But actually I made it for a friend. I guess I can just make her more later. She can, um, try this. Tell me if she likes it."

 

Her protege still looks hangdog so the varsity player puts on her best smile, "Seriously, it's no big deal. It's just a shake, right? Ha ha!"

 

Scootaloo's face brightens, "Sure! By the way, did you make that? It was really good!"

 

"Uh, glad you liked it."

 

Dash's scheming mind is running a million miles an hour. Glancing surreptitiously at her young friend's shirt she can see that the girl has few curves to speak of. A fact that will change by tomorrow morning. She can't tell Scootaloo what's about to happen but perhaps she can be there for her all the same

 

"So, um, I was thinking that maybe you'd like to go running with me tomorrow morning," Rainbow Dash offers.

 

Scootaloo's face lights up like a halogen bulb, "Really? Yeah, I'd love to. Where should I meet you?"

 

"I'll stop by at your house. Say 6:30?"

 

"Sure!"

 

"Great! Well, I got to get back to practice. Those balls won't kick themselves! Alright everybody! Let's run some drills!"

 

The varsity team groans as their gung-ho captain herds them back onto the field.

 

Scootaloo is grinning from ear to ear. Dash invited her to go running! She never invites anyone to go running with her except Apple Bloom's older sister. Tomorrow is going to be an awesome day, she thinks to herself.

 

...

 

Early the next morning, Rainbow knocks on her friend's front door. She waits for a few minutes, not sure if anybody's home, until she finally hears the pounding of feet coming up to the door. A disheveled Scootaloo flings the door open and says in a somewhat frantic voice, "Hey Rainbow Dash, I'm ready to go!"

 

Even though she has a pretty good idea why her companion is behaving so erratically, Dash decides to play it strait.

 

"You okay kiddo? You seem kind of freaked out."

 

"I'm fine!" the younger girl says a little too loudly, "We better get going, huh?"

 

"Right, let's get moving."

 

The mammary mastermind smiles to herself as they start pounding down the sidewalk. It's not easy to see under her running partner's baggy shirt, but the keen eyed purveyor of chest pillows can tell that Scootaloo's gained some new additions in the last twenty four hours. She can also tell that the frazzled youth has no idea how to properly strap those additions down!

 

"So how's it going, Scoots?"

 

"Fine! Just fine."

 

Dash almost feels bad, like she's messing with the poor girl.

 

"That's cool. You doing anything with your folks this weekend?"

 

"Nah. Dad's working and Mom's going to some conference."

 

Ouch.

 

Both of Scootaloo's parents are constantly working. Her dad is a lawyer and her mom, a marketing specialist. They have a posh lifestyle afforded by their dual salaries, but because they're never home, their daughter is a de facto latchkey kid. It's one of the reasons that Dash has 'adopted' her as her little sister.

 

"Ah, that's too bad. But hey, if you're not doing anything this Saturday I was going to go shopping. Want to come?"

 

"Shopping?"

 

"Yep. I'm still trying to find some decent clothes that actually fit these monsters," Dash rests her hands on her heaving bosom.

 

Out of the corner of her eye Rainbow can see Scootaloo looking down at her own chest.

 

"Yeah, that'd be great. Maybe I'll pick up something too."

 

"Cool. Then we'll hit some shops."

 

"Alright," the younger girl hesitates, then adds, "And maybe you can help me pick out some stuff too?"

 

Bingo, Rainbow thinks. Out loud she says, "Sure thing, kiddo."

 

They continue their jog.

 

...

 

Saturday, Rainbow leads the way as she and Scootaloo head to the only store that she really means to visit today.

 

Rarity's.

 

She had learned earlier from Fluttershy that if she wants clothes (and especially bras) that fit a top-heavy girl like her, she needs to look beyond the normal stores.

 

Fortunately, one of the best tailors in town happens to be a close friend.

 

The bell to the posh shop rings as Dash pushes the door open. Rarity sweeps into the front room, her usual greeting pouring from her lips.

 

"Welcome to Carousel Boutique, where the fashions are- Oh, it's you! And Scootaloo? My my, this IS an unexpected pleasure. So nice to see the both of you interested in a little haute couture."

 

"Mmn," mutters Dash, "I was just wondering if you can fit me for some new bras. My sports tops work pretty good, but I really need something for when I'm not running around, y'know?"

 

"Why Rainbow Dash, are you telling me that you want some proper lingerie?"

 

"What? No, I just, you know, when in Rome?" the consummate tomboy tries to avoid Scootaloo's curious gaze.

 

The fashion maven frowns a little, "I'm not sure... Mm, never mind. Let's get you fitted, shall we?"

 

They head back to the spacious fitting room and Rarity instructs Dash to take off her shirt. While she stands there in her sports bra, Rarity wraps a tape measure around the athlete's ribcage. As the designer leans forward, Dash can't help but notice that the top two buttons of Rarity's blouse are undone. Without really intending to, Rainbow gets a long look at her friend's plump cleavage and the lacy red bra it's packed into. She stares until Rarity huffs in frustration.

 

"This simply won't do! That spandex horror you're wearing is compressing you bust and I simply can't get a proper measurement. You'll have to take it off."

 

"Umm..." Scootaloo starts to fidget, "Do you want me to leave?"

 

Dash considers it but really, she thinks, it's kind of too late for that. The whole point of this trip is to get Scootaloo comfortable in dealing with womanly issues, like bra shopping. If Dash seems ashamed of her chest, then how will the younger girl react when it's her turn with the tape measure?

 

"You can stay, Scoots. It's just us girls, right?"

 

Dash struggles out of her stretchy top. Her confined tits spring forward making them look far larger than when bound by the sports top. While jog bras are excellent for keeping her naughty bits from flying all over the place, wearing them all the time does get uncomfortable.

 

Satisfied, the seamstress goes back to work with her tape measure. When she's finished she asks her client what styles she would like.

 

"I don't know. Does it matter?"

 

"Of course it does my dear! A full bra gives you the best support AND it can either emphasize you bust or minimize it. But of course you wouldn't wear that with a low cut top. For that you need a demi-cup."

 

"This sounds complicated," Scootaloo interrupts.

 

"Not at all!" Rarity retorts, "What kind of bra do you usually wear?"

 

Scootaloo gets a nervous look on her face, "Uh, w-what do you mean?"

 

Rarity gives the girl a kindly smile, "Darling, you may be wearing a t-shirt that's two sizes too big for you but you can't fool me." The shop owner turn to Rainbow, "I think we're done for now. I'll show you some designs in the main room. Now, Scootaloo, why don't you take off that shirt and we'll take care of you too."

 

"M-me?"

 

"Of course! How can I fit you for something if I don't have your measurements? Come now, chop chop!"

 

After some additional encouragement from Rainbow, Scootaloo hesitantly grabs her shirt and lifts it over her head. Underneath, she sports a perky little pair of breasts with puckered pink tips about the size of quarters.

 

"Hmn, that's what I thought. You really should be wearing a bra, Darling. Honestly, it's nothing to be ashamed of. I know at first some girls don't like wearing them because they think they'll draw attention to themselves, but you can't go around without one. It's simply not done!"

 

"But I don't have any bras," Scootaloo explains, "I didn't even need one until a few days ago!"

 

"I don't follow," a confused Rarity says, "What do you mean 'a few days ago'?"

 

"Well..." the younger girl looks to Rainbow Dash as though silently asking for help, "The other morning I woke up and, uh, I had breasts!"

 

"Ah my dear, surely you're exaggerating! Things can change very fast at your age and I'm sure you simply didn't notice what was happening to your body until recently."

 

"Nuh-uh!" Scootaloo whines, "I was totally flat! I remember because Rainbow Dash invited me to go running so I picked out my clothes the night before and took a shower and when I washed my chest I didn't have anything!" The underclassman takes a deep breath, "And when I woke up the next morning I had these bumps on my chest so I took off my shirt and I had boobs!"

 

Startled by Scootaloo's outburst, Rarity tries to process what she's just heard. The whole pattern laid out in Scootaloo's rant sounds far too familiar for comfort. She gives Rainbow Dash a sharp look but the varsity girl is purposely looking away. Remembering that she has a very uncomfortable first time client standing half-naked before her, Rarity does her best to allay the fears of her new charge.

 

"Don't worry, my dear. I suppose I misspoke just now. It may be rare for breasts to develop so fast, but if that's what happened then who am I to say otherwise? In any case, the fact remains that you definitely need a good foundation garment now! Arms up."

 

With a practiced swiftness, the skilled seamstress pulls her tape snug across several points along Scootaloo's torso. She compliments the developing girl on her new curves. Not that she believes for a moment they they occurred naturally, at least not without a little help. For one thing, they're just a tad too big to have grown so quickly. Each shallow dome is about the same size as a large tangerine, though spread out across an area the size of the girl's palms. The fresh young breasts are also too well developed. Their firm, shallow slopes are a far cry from the more immature cones that most of Scootaloo's contemporaries have.

 

"Well, you have some nice measurements my dear. And you are officially an A-cup."

 

Scootaloo doesn't know whether to smile or cry, "That means I'm too big for a training bra?"

 

"Indeed it does. I hope you're not too disappointed."

 

"No! Uh, no. That's cool. You know, whatever..." Rarity chuckles at Scootaloo's attempt to downplay her excitement.

 

"Well the good thing about your size is that you have far more options when it comes to cute bras then someone like Rainbow Dash."

 

"But what's the point of wearing a cute bra if no one's going to see it?" Dash nods her head, thinking the same thing.

 

Rarity laughs, "Because it makes you feel beautiful, Darling! Knowing that you have a lovely set of lingerie on, it makes you feel more confident. After all, the idea of wearing a real grown-up brassiere is quite exiting, is it not?"

 

Scootaloo blushes even as she grins and nods her head. Rarity chuckles and tells the girl to wait a moment as she steps out of the dressing room. When she comes back in she has several boxes with her. Opening one, she pulls out a light purple bra and hands it to her eager client. Scootaloo handles it gently like it's made of tissue paper.

 

"Don't worry, it may look delicate but I assure it's a lot stronger that it looks. They have to be with all the stress they handle! Here let me help you put it on."

 

Rarity show the inexperienced girl how to work the clasps and properly seat her pert mounds in the lacy demi-cups. When they're done Scootaloo turns and looks at herself in the mirror.

 

"Whoa..." is all she can manage. Both upperclass-students look at each other and share the look of a job well done.

 

"Now, why don't you try on the rest and see what catches your fancy. I'm going to take Rainbow Dash here and show her some designs out of my catalogues in the main room. We'll be back."

 

As soon as they are out of earshot of Rainbow's young charge, Rarity rounds on the other young woman.

 

"I am terribly disappointed in you Rainbow Dash! It's one thing to do it to me, but then after our conversation the other day you go and give your milk to Scootaloo? No, don't deny it! Well, what do you have to say for yourself?"

 

Dash sighs, knowing that this was coming. She explains about the milkshake she made for Applejack and how Scootaloo accidentally drank half of it. She also explains that she brought the younger girl to Carousel Boutique because she wanted to help her protege learn not to be ashamed of her new assets.

 

Hearing her friend's explanation calms Rarity down a bit. But she's still not satisfied.

 

"You've put me in a difficult position, you know."

 

"What do you mean Rares?"

 

"I mean Sweetie Belle! She's such a trooper but I know she's been having a rough time lately because so many of her friends are developing and she's not. And now Scootaloo's going to show up to school on Monday with a brand new bra," Rarity looks genuinely upset, "I... know what it's like to feel inadequate because all the other girls need bras and you don't."

 

An astonished Rainbow looks at the fashion plate standing next to her, "Really, Rarity? But you're, like, one of the most confident people I know."

 

"Oh pish posh! Why do you think I've always been drawn to fashion? If I look good it makes me feel better about myself. To be frank I've always envied how you can just run around wearing whatever."

 

"Gosh, I- I had no idea."

 

"Yes, well, now you know why I'm concerned about Sweetie Belle. And it's doubly unfair if one of her friends is getting an unfair advantage in the bust department."

 

"Yeah, I see what you mean. But it really was an accident!"

 

"I know. It's just... You know, I haven't met a single girl that doesn't wish for more up top? I know I've certainly been enjoying my enhancements." Rarity folds her arms underneath her bosom and pushes up on it a little, letting a hint a cleavage show through the top of her blouse. "I'm almost tempted to ask you for more of that pudding."

 

"Heh, funny you should mention that," Rainbow Dash gets a tight grin on her face, "You know how I said before that I wanted to 'share the big boob love'? Well me and Fluttershy have been thinking about a bunch of stuff and I think we've come up with a pretty interesting idea. You wanna hear it?"

 

"Sigh, I suppose."

 

Rainbow Dash outlines the scheme that her and her bosom buddy Fluttershy have concocted. At first Rarity is horrified. Then she is intrigued. By the time her brash friend is finished detailing the endeavour, the fashionista is fully on board.

 

The following weekend is a whirlwind of activity for Rainbow Dash and Fluttershy. When Friday rolls around and the lunch bell rings, the students of Canterlot High eagerly make their way to the cafeteria. Near the entrance they see the two bustiest girls in the entire school standing behind a table with home made posters and a large cooler.

 

The hand lettered signs signs read:

 

Support the Canterlot Animal Shelter!

Chocolate Pudding $1.00

Tapioca Pudding $1.00

 

One per customer

 

The first one in line is Pinkie Pie. Her generous chest bounces along with the rest of her as she giggles and carries on while her friends finish getting set up.

 

"Gosh! I had no idea you were doing anything like this! I can't believe you didn't ask me to help you, but I guess that's okay because that means I get to sit down and enjoy pudding! I love pudding. Are you sure I can only have one? Because I love chocolate but I love tapioca just as much! Maybe you could sort of mix 'em together..."

 

"Pinkie!" Rainbow snaps, "You can only have one, okay? (Like you even need any..)" she mutters, eying her friends copious chest.

 

"What was that?" Pinkie Pie asks.

 

"Nothing!" Dash scoops a large dollop of chocolate pudding into a paper bowl and hands it to her hyperactive friend, "Here. One dollar."

 

"Here you go! Mm This ish sho good! I've had a LOT of chocolate pudding in my time, but there's something about this chocolate pudding that I can't quite put my finger on. Share your recipe?"

 

Fluttershy fidgets under her friend's intense stare, "Oh, I'm afraid not. I-It's kind of a secret."

 

Dash reminds Pinkie that there are more customers waiting and the line gets moving once again.

 

Several more people make their purchases, each one commenting on how delectable the creamy treats are. After a member of the boy's basketball team leaves, Rarity and Sweetie Belle make the front of the line. Eying the boy who has just left, she turns frantically to the two salesgirls.

 

"Rainbow!" she hisses, "You're selling it to guys! Isn't that bad?"

 

Dash leans in and lowers her voice, "Relax. We tested a batch on Monday. Gave normal pudding to the Varsity Football team and gave those three knuckleheads that're always giving me grief a doctored batch. They didn't grow any man boobs."

 

She snickers, "Though that WOULD have been pretty great."

 

Rarity gives a small sigh of relief and regains her customary poise.

 

"I suppose that's fine then," turning to her little sister, Rarity asks, " Sweetie what would you like? My treat."

 

"Umm..." the slim girl waffles on what to get.

 

Rarity gestures at the table, "Why don't you get one flavor, I'll get the other, and you can have mine as well."

 

"Really? You don't want yours Sis?"

 

"You've been such a dear this week, consider it my way of saying thank you."

 

"Gosh, thanks Rarity."

 

Rainbow dishes up a bowl of each flavor. As the sisters turn to leave, she leans over and snarks in her friend's ear, "Trying to get her into D-cups before the Fall Formal?"

 

Rarity turns her nose up, "Be sure not to let Scootaloo have too many of those leftovers, Darling. You don't want her waking up tomorrow wondering why she needs a minimizer bra."

 

Dash sticks her tongue out as the siblings walk away. The next pair in line is a bit unexpected.

 

"Principal Celestia! Vice-Principal Luna! Come to, uh, see how the sale's going?" Rainbow stammers.

 

"Indeed we are Ms. Dash," Celestia responds, "And we thought we'd get some of this wonderful pudding everyone's been talking about."

 

The athlete-turned-fundraiser hears her co-conspirator give a small 'Eep!'. Silently she screams at her friend to play it cool.

 

"Sure, sure..." Dash blithely agrees. She asks what flavors they both want and gives the administrators their bowls.

 

"On the house," she declares.

 

"Oh no. We'll pay," the vice-principal insists, "We DO want to help all those unfortunate animals, after all."

 

"Huh?" Rainbow asks. Fluttershy nudges her, "Oh yeah! Gotta support that animal shelter. Heh heh."

 

Both sales girls wait as their principal tries her pudding. While she does, Rainbow idly watches the way Celestia's full bosom pulls and strains the buttons on her dress shirt. She never really thought about it before but their principal is pretty built!

 

Luna is the more svelte of the two siblings, her small breasts definitely noticeable but far less so than her older sister's.

 

Her head full of dire scenarios, Rainbow Dash turns to her cohort as the two satisfied administrators leave.

 

"Okay, next time? We make a batch without the 'special ingredient' to give to Pinkie and Principal Celestia."

 

Fluttershy giggles and they go back to selling their wares.

 

...

 

The bell rings as Rainbow enters Carousel Boutique. Seeing who it is, Rarity waves her back and pulls out a few packages containing custom bras for her client. In the fitting room, Dash tries on her new lingerie while Rarity congratulates her on the past few weeks.

 

"I had my doubts, but you've really pulled it off. I daresay that the your weekly pudding sale has become the toast of the school. And I've also noticed that it's having the desired effect on certain bodies in the student body," Rarity titters at her own joke, Rainbow rolls her eyes.

 

"Did you know your little shadow was in here the other day?"

 

"Oh?" that's news to Rainbow Dash.

 

"Yes. Scootaloo needed a new fitting. The poor thing was simply falling out of her top! I don't believe she ever thought she'd be wearing a B-cup."

 

"Good! Speaking of which, how's Sweetie Belle doing?"

 

"Mmn, those double doses, diluted as they may be, have really done the trick. She's still not as big as as her two friends but she's getting there. And since we're talking about the others, how much of your special ingredient did you give Applejack? I swear she's bigger than I am!" Rarity brushes an imagined speck off her D-cup shelf.

 

Rainbow chuckles, "Hey, I told you. You can have more if you want. AJ just decided that she wanted to go bigger, that's all."

 

"Hmn. If you say so, Darling. By the by, I thought you were going to let certain girls have the regular pudding and reserve the doctored stuff for those 'in need'."

 

"Yeah, we've been giving Principal Celestia and those two brats that always pick on Scootaloo and her friends the fake stuff." Dash chortles, "But we have been giving the vice-principal the real stuff. Figured she'd like catching up to her big sister."

 

"You are having entirely too much fun, you rogue. But no, I'm talking about Pinkie Pie! I had to fit her for a new F-cup last week. If this keeps up she'll be as big as you before long."

 

"Argh, I know! We'd tried giving her the fake pudding but she noticed the difference. Said we must have made a defective batch. When we gave her the real stuff she was all, 'That's better!'. We haven't been able to fool her since."

 

"Oh my. Well, how much longer do you think you're going to keep this up?"

 

"I don't know. I think we'll know when we get there. Besides Flutters is making a ton of money for the shelter. And the bustier everyone else gets the less she stands out."

 

"And what about you? I thought you loved standing out?"

 

"Eh, maybe if I was working as a model or something."

 

Rarity smiles to herself, "I see. Well I think we should all get together and hang out one of these nights. Make it a sleep over. We could even invite Sweetie and her friends."

 

"Yeah, that sounds cool. Maybe in a few weeks," Rainbow slumps a little.

 

"What's the matter, Darling?"

 

"To be honest, I've kind of been thinking of giving this milking stuff to someone else. Having to pull out the pumps every morning and night is getting kind of old."

 

Rarity's eyes widen in surprise, "Have you given any thought who you might want to give it too?"

 

"Nah. I'll figure it out later. Here, let's see one of those bras."

 

...

 

"Hello? Rarity?"

 

"There you are Fluttershy! Come in. So glad you could make it."

 

"Thanks. It's been a while since I've been to a sleepover. The last one was when I had Rainbow Dash over at my place and that was..." the pink haired young woman thinks, "Almost four months ago."

 

"I know. I suggested this to Rainbow some time ago but it took a while for all our schedules to line up. I think what really got everybody together was-" Rarity is interrupted by a familiar voice at the door.

 

"Hey, girls. How are you?"

 

Fluttershy and Rarity both turn to the door, delighted looks on their faces.

 

"Twilight!" they both cry in unison.

 

Rarity rushes over to their long absent friend, "Pinkie told us that you were back. How has it been, staying with her?"

 

"Good! Kind of crazy, but that's Pinkie Pie for you. She told me about the sleepover this morning."

 

The proprietress of Carousel Boutique ushers both her guests into the back and up the stairs to the apartment on the second floor, gabbling all the way.

 

"Indeed. We had been waiting for a good excuse and now that you're... Look who's here Applejack, Apple Bloom."

 

"Howdy, Twi!"

 

"Hello, Miss Twilight."

 

"Hi Applejack, Hi Apple Bloom. Wow! Apple Bloom, you got tall since I last saw you!"

 

The lanky farm girl chuckles and looks a bit bashful, "Yup, I reckon so."

 

"It's all we can do to keep that girl in clothes!" adds her older sister, "I've been lendin' her my hand-me-downs. Problem is, if the pants I give her are long enough, then they end up bein' too big around!"

 

Apple Bloom shoots back at the older girl, "Well 'scuse me for not havin' your big butt!" she tugs on her pearl snap shirt, "At least I'm fillin' out the top half of my clothes."

 

Since arriving the previous day Twilight Sparkle, visitor from another world, has had a nagging feeling that something is different with her friends. After seeing the orange sized mounds distorting Apple Bloom's shirt, it all clicks into place.

 

"Now I know what's bugging me. Everyone's mammary glands have gotten bigger!"

 

A dead silence fills the room. Rarity is white as a sheet while the other girls are blushing intensely. Before anyone can say anything, Rainbow Dash comes swaggering in followed by Scootaloo's other two classmates.

 

"Hey everybody!" Rainbow Dash calls, "The life of the party's here. I parked out back is that okay? Oh, hey Twilight! Good to see you."

 

"You too! Wow, your mammary glands have really gotten big! Is this some kind of biological thing? Or maybe a social custom to increase their size? Ooh, I know you don't have magic, so do you have some kind of advanced human science that lets you make them bigger?"

 

The bookworm's eyes are shining with curiosity. Everyone else is mortified.

 

Except for Applejack who starts giggling, then cackling, and finally laughs so hard that tears form in her eyes. It doesn’t take long before the rest of the young women join her, except for Twilight who is now thoroughly confused.

 

Rarity, still laughing, looks to her side to see Pinkie Pie, who has been absent until now, standing next to her guffawing with the rest of them.

 

"Bwa-ha! Pinkie! When did you get here?"

 

"Ha ha ha! I just showed up! Ha ha! Why are we laughing?"

 

Rainbow Dash, tears streaming down her face, lays an arm around her hyperactive friend, "Because Twilight just called us all out for growing boobs!"

 

"Really? Ha ha ha! That's hysterical! And it's even funnier because it's true! I mean I've gone up three cup sizes in the last couple of months."

 

Before the rest of the room can react, Pinkie Pie whips off her shirt. She twists her voluptuous torso first one way and then the other. Her bright pink bra, filled to the brim with her massive tits, creaks with the strain.

 

She hooks her thumbs under her shoulder straps, "Tada! H-cups!"

 

Once again, an uncomfortable silence descends on the group. At least until Rainbow Dash decides to break the tension in the room.
