>It's another sunny day in ponyville
>The winter moon celebration is in a few days 
>"Wowzie! A letter from Princess Celestia?"
>Pinkie Pie opens her mail in Sugarcube Corner
>"Dear Sugarcube Corner Bakery: The Royal Sisters would like to cordially request you to provide baked goods for the Winter Moon Celebration. We request 800 servings of..."
>The list requests many milk-based desserts
>"Oh my gosh! I've never seen a list of goodies that need this much milk before! There's no way I'll be able to make all these alone! I'll need the help of one of my friends..."
>cut to Fluttershy in her cottage
>"Alright you little good little critters, I'm going to get my drink ready for you all now."
>Fluttershy sits and looks down at her enormous soft teats, each as big as a soccer ball, and attempts to slide one nipple into a suction cup
>Leaning forward causes her teats to gurgle and spray a small stream of milk at the wall 
>"Oh, my..."
>Fluttershy blushes and carefully puts a cup around her right nipple 
>Her teats start to throb with anticipation and her breath quickens
>"Settle down girls, we need all the milk we can get for-"
>"Fluttershy! You'll never guess what just happened! There's a Winter Moon Celebration and Princess Celestia is going to be there and she asked for 600 servings of custard and-bang!"
>Pinkie Pie trips over the rug at the doorway and lands on her face
>"What's going on Pinkie?"
>Pinkie Pie springs up off the floor
>"Sugarcube Corner needs your help make desserts for the Winter Moon Celebration!"
>"Oh gosh! The Winter Moon Celebration? There's going to be so m-many ponies there..."
>Fluttershy hides her face behind her mane
>"Don't worry Fluttershy, we'll serve all the guests ourself. We just need your milk for all the recipes!"
>Fluttershy blushes and feels her teats start to churn at the thought of it
>"Oh, ok Pinkie. I would love to help by giving my milk."
>"Thanks Fluttershy! Sugarcube Corner will pump out those desserts tomorrow so they'll be nice and fresh for the celebration."
>Flutter's nipples stiffen when she hears the words "pump out"
>"Tomorrow? But there's no way that we'll have enough time to produce that much milk!"
>"I've got it all taken care of Fluttershy, Pinkie Pie's the pony with the plan. Just come with me to Sugarcube Corner."
>Pinkie subtly grins greedily at Fluttershy
>"Well, whatever you say Pinkie. I'll feed the critters with some other food before I go."
>All the animals look sad to get fed regular food instead of milk
>Fluttershy and Pinkie walk back to Sugarcube Corner
>"Alrighty Fluttershy, I got this potion from Zecora. She said: Give the pony who drinks lots of feed, and you'll have all the milk you'll ever need. Drink up!"
>Fluttershy is given the potion and looks worriedly at Pinkie
>"Pinkie, w-what's this potion going to do to me?"
>Pinkie Pie shrugs
>"Drink it and find out!"
>"Well ok, Pinkie, but only because we have to try and feed all those ponies."
>Fluttershy chugs the entire potion and sets down the bottle
>"Um, I don't feel any diff-" "grrrrrrgle"
>Fluttershy is cut off by the sound of her belly
>Fluttershy blushes cutely and rubs her belly
>"Excuse me, I don't think I've had my lunch yet. Could I please get some hay?"
>"Sure thing Fluttershy, Sugarcube Corner has the hay store for all of ponyville!"
>Pinkie Pie leaves and shortly brings back one meal's worth of hay
>"Oh thank you Pinkie, I am famished!"
>Fluttershy quickly and loudly devours the hay in front of her 
>"grrrrrmbl... Uh, Pinkie? Um... If you wouldn't mind, I think I might need..."
>Fluttershy looks down at her belly
>There's a small, noticeable bulge in her tummy from eating all the hay
>She still feels hungry though
>"I, um, I'd like some more. If you wouldn't mind, that is."
>"Sure thing Fluttershy, anything for a friend in need!"
>Pinkie Pie gets one more serving of hay from the store
>"Eat up, Fluttershy! We need you in prime milking condition for tomorrow."
>"Thank you so much Pinkie, I hope it's alright that I'm having two helpings."
>Fluttershy's belly groans again and her teats gurgle between her thighs
>"I'd better get this down quickly so we can get to milking..."
>Fluttershy munches down the hay in front of her
>"Mmm, Mmph, gulp, crunch, mmm! Wow pinkie, this hay really hits the spot! Thanks aga-gurrrooop!"
>Fluttershy's tummy cannot be satisfied, making louder noises than before
>It's starting to expand into a rounder shape than before
>"Oh no! Pinkie, could this be the effects of that potion? What's happening to me!"
>"It's ok Fluttershy, Zecora is our friend. There's no way she would give us a potion that could hurt us, right?"
>Fluttershy's face relaxes and she smiles
>"You're right Pinkie. If this is the potion's doing, we'll just have to do what we can to use it." "grrrrrrmble"
>Flutter's belly loudly demands more, causing her to hide her face behind her hooves in embarrassment
>"Just, as long as you don't mind me making these... noises"
>Pinkie smiles wildly
>"Do I mind? No way! I'll get you as much hay as you want!"
>Fluttershy bashfully smiles and gets seated comfortably on the floor
>"I sure hope this turns out ok..."
>Pinkie pie returns, pulling a stack of hay bales on a pallet for Fluttershy
>"This will do it!"
>Pinkie is so busy getting the hay that she starts to drip milk onto the floor, it's well past time for her milking
>Fluttershy starts eating the hay, and begins to lose herself in ecstacy
>Soon she is mindlessly forcing hay into her mouth, unaware of her belly turning into a soft, growing mound underneath her 
>All Fluttershy can think of is how good stuffing her tummy with hay feels
>"Rrrmmmpph, mmph, gulp, munch, mmrph!"
>Pinkie sees Fluttershy almost eat the entire hay pallet, and goes to bring out another
>"Here's another pallet for you Flutter-"
>Pinkie pie stops when she sees Fluttershy off of the ground on top of her big sack of a belly
>A large white tribal tattoo of a milk splatter begins to appear on her belly and nipples
>"cough! Pinkie, I'm getting thirsty. Could you please get me something to drink?"
>"Sure thing friend, Pinkie's got all the water you need here at Sugarcube Corner!"
>Pinkie leaves in a dash and brings back a glass of water in a cartoony effect
>"Thanks Pinkie, but it would be nice if..."
>Fluttershy looks away and mumbles something at the floor
>"What was that?"
>Fluttershy turns beet red
>"I said, it would be nice if I could have... your milk instead..."
>Pinkie Pie blushes and looks down at her dripping melon-sized milk factories
>"Well, it is time for my milking after all... I wouldn't mind giving you some of my milk, Fluttershy!"
>"Oh thank you Pinkie! I knew I could count on you! You're the best friend a pony could ask for!"
>Pinkie Pie blushes harder and looks away
>"Aww, thanks Flooty!"
>Pinkie Pie climbs up on Fluttershy's belly and lowers her crotch onto Fluttershy's face
>"They're all yours, Fluttershy!"
>Fluttershy grabs her left teat and begins to suckle
>"Aah! Careful Fluttershy, they're sensitive!"
>Fluttershy stops and slowly licks her erect nipple 
>Her nipple throbs repeatedly until it starts to churn and squirt out milk onto Fluttershy's hot tongue
>"Oh, this is so dirty! You're drinking my milk like... a newborn foal!"
>Fluttershy blushes hard and suckles more milk
>Pinkie rocks back and forth on fluttershy's face, idly slapping her other teat onto Fluttershy's face
>"slosh, slap, sqrt! slosh, slap, sqrt! Oooh! Fluttershy! It feels so good! Don't stop!"
>"Mmhmph! gulp gulp gulp gulp..."
>Fluttershy's belly groans and gurgles with the addition of Pinkie's milk
>"Yes Fluttershy! It's emptying all out in your mouth!"
>"glurp gulp sip gulp!"
>Pinkie's marehood winks and wettens all around her hind legs, dripping arousal onto Fluttershy's belly
>Fluttershy raises her tail and winks mare juice strands behind her
>"Ah, ah hah, oh, gasp, gasp, Fluttershy... Now, do my other teat please..."
>Fluttershy pops her mouth off of the teat
>"I would love to, Pinkie. I'll drink all the milk you can give."
>Pinkie audibly winks and smiles lewdly
>Fluttershy has milk all over her mouth and a drop dribbling down her chin
>The next teat slides into Fluttershy's mouth, slickened by the creamy milk all over it
>"Ahh! Mmm!"
>Fluttershy circles her tongue rapidly over Pinkie's conical nipple, causing milk to quickly gush out
>"Aaaaaah!"
>Flutters drinks it all down like a greedy foal on the brink of starvation
>The warm pulse of Pinkie's teat can be felt as Fluttershy massages the milk out of it
>"I'm! Oh goodness! I'm about to!"
>Pinkie's eyes shut hard and slimy mare ejaculate squirts out of her while she lets the last of her milk down into Fluttershy's mouth
>"Aah! Oh! Ahh! Yes!"
>Fluttershy winks rapidly as she hears her friend's orgasm splatter onto her belly and the floor
>"Fluttershy, you made me... Oh wowie!"
>"pop! I hope it felt lovely, Pinkie. Yawn! I... I think I'm finally full now. glorp!"
>Pinkie turns around to cuddle fluttershy on her massive, soft belly
>"Yawn! You're the best friend a pony could ask for too, Fluttershy!"
>"Mmm..."
>Both ponies drift off to sleep on fluttershy's bed of a tummy
>Pinkie wakes up on Fluttershy and the floor, confused
>"Good morning Flutters!"
>"Ah? Good morning Pinkie."
>"Say, what happened to your belly?"
>"My belly? It's normal, but I ate all that hay yesterday, and... your milk."
>Both ponies blush
>Pinkie gets up, and Fluttershy tries to get up
>"Humph! What's this weight on me?"
>Fluttershy looks behind her to see her veiny, throbbing teats the size of five ponies behind her
>Both teats have the white tribal tattoo that looks like a milk splatter on each nipple
>"throb, slosh, throb, slorsh"
>"Oh, my. I guess that's where all the hay went."
>"Give the pony who drinks lots of feed, and you'll have all the milk you'll ever need! That's what the potion meant!"
>Pinkie Pie springs around Sugarcube Corner in a dance, having figured out the riddle
>"We did it! We did it! We did it! Now we can make our desserts!"
>Right on time, Mr. and Mrs. Cake walk in
>"Hey Pinkie, we're ready to start making the- Oh sweet Celestia what are those!?"
>"Hi Mr. and Mrs. Cake, Fluttershy came to supply the milk!"
>Fluttershy hides her face behind her mane in embarrassment
>"Eep!"
>"Well, we don't have any time to waste! We have to make these desserts on short notice, so get moving everypony!"
>The Cakes and Pinkie hurriedly begin dumping ingredients into bowls, knowing each recipe by memory
>Each pony worked in perfect tandem with the other
>"Flour! Flour. Sugar! Sugar. Eggs! Eggs. Milk!"
>Pinkie aims Fluttershy's teat into the bowl with one hoof and squeezes the massive teat with her other foreleg
>"throb! Ah! spshhhhh! Milk. Wow Fluttershy! You're just like a big piping bag!"
>"Squee!"
>This goes on for an hour until hundreds of batches of puddings, custards, creams, fillings, and other dessert ingredients are made
>"Knock! Knock! Knock! Good Afternoon Sugarcube Corner, I'm Twilight Sparkle and I'm here to prepare for the Winter Moon Celebration!"
>Twilight's jaw drops open as she sees Pinkie turn her head around while squirting fluttershy's milk from her massive teats into a bowl
>"Hiya Twilight, no time to explain, we're making dessert!"
>"I see... Well, I'll leave you to it then, hah, hah..."
>Twilight slowly backs away and closes the door behind her
>Galloping could be heard outside, shortly after heavy breathing
>Pinkie keeps dispensing the milk from Fluttershy for the baked goods, occasionally licking her nipple if the milk hesitates
>Sometimes she tries a little as well, for testing batch consistency
>"Wow Fluttershy, I've never seen a pony with teats this big before sluuuuurp! suck! gulp!"
>"Aaah! Pinkie! You dirty mare! I'm just here to provide m-my milk for the batches! That's it! But c-could you d-do that again? I-If you wouldn't m-mind, that is"
>"Hmm, I don't know if that last one tasted weird, let me try it again... slulululululurp! Nope!"
>"Ahhahhhaah! You're driving me crazy!"
>"Are you saying you want to take a break? slosh, slosh, slosh, I know this might be real hard on your teats so-"
>"Don't stop! Please!"
>"Alrighty then, no breaks it is!"
>Pinkie licks inside of her nipple hole while she holds it with her lips
>"grrrrrrrblrrr! That's my! Aaaaaah!"
>Fluttershy creams her hindquarters and pinkie's mouth
>"Sliiiiuuuurp! Gulp! Pop! A good friend always returns the favor, Fluttershy!"
>"T-thank you, Pinkie."
>Pinkie squirts more milk into the batches, with some of her own until the desserts are all prepared for the celebration
>Fluttershy's teats finally shrink to the point where she can stand once the bakery is closing
>The tribal markings start to fade
>"Thanks Fluttershy, we couldn't have done it without you!"
>"Well Pinkie, I'm honored that I could h-help."
>"We hope we can use your help if we ever need it. So what'ya say?"
>"Oh, my... I-"
>Pinkie gives Fluttershy a quick peck on the lips 
>Fluttershy's face turns bright red
>"We'll be serving these treats to everypony now, thanks again Fluttershy!"
>"S-see you later, Pinkie."
>Fluttershy closes the door and walks away, her teats a fair bit larger than a few days ago bouncing when she walks
>"Maybe sooner than later, he-he!"
