Fluttercow

 

Fluttershy's soft voice did well to mask her current mood. Her wings were flared out in a total panic and her knees were shaking. She looked around with every step, hoping nopony could see her in this corner of the apple orchard.

 

“No worries. You're a friend of Applejack and you need help. We'll get this fixed.” Big Macintosh's voice was gentle as could be, filled with firm confidence he could help Fluttershy. “We'll just hide away in this here barn for a bit. Make sure we stay hidden so nopony sees your...condition.”

 

Fluttershy looked over Big Mac's shoulder. The barn in front of them had seen better days but it was perfect for seclusion. It was as far away from the Apple home as possible and the trees had already been picked for the season. Nice and quiet.

 

Big Macintosh heaved the door open with ease. “Step inside and you can tell me all about it.”

 

The red stallion had just enough time to close the barn door before Fluttershy cracked. “Okay! Okay....so...so...so...there was a new type of animal feed...r-r-ready for use, it said. I was gonna give it a try and hand it out....but...but...the bag! The bag was so heavy, and it ripped and the food got everywhere and it got in my mouth and I've eaten critter food before and it's actually not that bad!

 

But this stuff? It was bad. REALLY BAD! I could taste something awful about it and I gagged and swallowed some and I TRIED to spit it all out and clean it up but then my tummy grumbled and I couldn't stop! I ate the gross animal food until it was all gone and when I finally stopped, I saw this!!!!” Fluttershy reached behind her and grabbed her tail.

 

Except it wasn't her pink, flowing tail anymore. It had been replaced with a long, skinny tail of a cow. Her coat was adorned with white splotches from her head to her hooves. “So then I walked over to a mirror and I saw THIS!”

 

Fluttershy turned around and raised her tail. Resting against her legs was a round, pink cow udder. She turned to face Big Macintosh with tears in her eyes. “I didn't know what to do! The company that makes the food wouldn't answer the phone and I was so embarrassed! I couldn't ask Twilight for help...I needed a pony who could keep a secret and I know you don't really talk a lot and you also take care of cows here and...and...I NEED YOUR HELP BIG MAC!!!”

 

“Aw, shush. Calm down, lil missy. Your secret is safe with me.” Big Macintosh did his best to calm down Fluttershy. “Now. Do y'all still have that phone number?”

 

“N-No...I left the package of food at home...” Fluttershy whimpered.

 

“Okay, that's not a big deal. Ah can do a little checkup on ya and then Ah suppose there's a visit to Zecora in our near future. If anypony can help, it's her.”

 

“Y-Yea...Zecora can help. Oh goodness, I didn't even think about that. I'm so glad I have your help, Big Mac.” Fluttershy said. She smiled at the farm pony and sighed.

 

“It's no problem. Now, we dunno what that feed has done, so Ah just wanna check a few things. Is that okay?” Big Macintosh asked.

 

“Sure...as long as I ask you something first...” Fluttershy bit her lip. “Wh-What do cows eat?”

 

“Uhh...hay, usually. Grass. Oats. They have the same kinda diets as ponies, Shy.”

 

“Oh...well...in that case....oh gosh...” Fluttershy trailed off, hiding her face behind her mane. Her belly gurgled loudly, making the shy cow pony blush hard.

 

“Haha...I see. Gimme a minute and Ah'll fetch a fresh bale o' hay for ya.” Big Macintosh ran out of the barn as fast as he could. The quicker he got this situation under control, the better.

 

“Mmm...Mmmm! Oh goodness, has hay always tasted this good?” Fluttershy moaned through big bites. She simply couldn't help herself.

 

“Ah think you're hungry because now ya got four stomachs. Cows need a lot of food to have the energy for their big bodies and to make milk.” Big Macintosh explained.

 

“M-Milk? You really think I'd make....milk?” Fluttershy asked.

 

“Well, Ah dunno. Just focus on eating and we can get the exam over and done with. Don't think too much about what Ah'm doin'. Just keep eating.”

 

Fluttershy did what she was told. Her muzzle was deep in the bale of hay as Big Macintosh began his health check. Fluttershy's coat was shiny and healthy. No problems with that. Her ears had definitely changed shape from narrow and pointy to wide and round. Mane still looked fine but obscured the top of Fluttershy's head. No way to tell if there were horns at all.

 

Big Macintosh looked over and saw that Fluttershy had already devoured half of the hay bale. Unusually large appetite. Something about her body was using a lot of energy. Big Macintosh poked and prodded at Fluttershy's belly. Nothing seemed out of place.

 

A loud gurgle disrupted Big Mac's concentration. Something was sloshing and churning deep within Fluttershy's belly. Big Macintosh stared at Fluttershy's barrel and body, waiting for anything to happen. There was another loud glorping noise as Fluttershy's body suddenly ripped with a thick layer of fat.

 

“Aw jeez...Ah may have just made things worse...” Big Macintosh thought to himself. He moved in close and poked and prodded some more. There were more gurgles happening and it was probably too late to make Fluttershy stop eating. “It'll be fixed when Zecora helps out...or afterwards and a lot of walking.”

 

Big Macintosh leaned down to check Fluttershy's udder and gasped. It had tripled in size and her teats were twitching. This cow needed to be milked badly but the old barn didn't have the equipment for it. “Hey Shy...let me know if this hurts.”

 

The stallion reached out with a hoof and gently pressed against Fluttershy's udder. A instant reaction. “OoooooooOOOOohhhhhhh.....wh....what was that?” Fluttershy moaned.

 

“Did that hurt?” Big Mac asked.

 

“.....No.....”

 

Slowly, Big Mac tried again. Fluttershy moaned louder, replacing the noises of her chewing. Big Macintosh was thankful his coat was red or else Fluttershy might have seen his blush. He pressed his hoof against the soft, malleable organ and caressed it. Cows need proper attention before a milking.

 

“M....More....” Fluttershy begged.

 

Big Macintosh reached out with his other hoof and gently rubbed the udder all over. Fluttershy buried her face into the remaining hay and screamed. She slumped forward, wagging her udder and rear about in a haze.

 

Big Macintosh was at a loss for words. A certain, familiar smell had filled the barn and it was making his head hazy. His cock stirred in its sheath, slowly hardening to the scent of a mare in post orgasmic bliss. He continued his admiration, rubbing his hooves all over the round, tight, sloshing udder.

 

His head foggy, Big Macintosh reached out and buried his face against the udder. He placed tender kisses up and down the needy organ, making it twitch in his hooves. The smell was getting stronger, overpowering Big Mac's mind the longer it filled his nose. Big Macintosh licked his lips, then went in for a drink.

 

Careful. Gently. His approach was full of respect and admiration. Big Macintosh lightly bit on the closest teat before wrapping his lips around it and giving a small suckle. Fluttershy screamed again, nearly collapsing on top of Big Macintosh as he nursed from the bloated cow.

 

Milk sprayed everywhere. All over the barn floor, all over Big Macintosh and inside his mouth. He drank as much as he could before taking a massive gulp of the sweetest milk he had ever tasted. Reluctantly, he released the teat from his mouth and let Fluttershy drain herself.

 

There was a glow in the air. Big Macintosh was still light headed as he rest on the barn floor. Another loud gurgle filled the air as Fluttershy's new body continued to digest the hay. Her body fattened up again, leaving her softer and doughier all over. Big Macintosh looked down and bit his lip as Fluttershy's udder was brushing against the ground.

 

The round, soft belly...the cute moaning and screaming...her bouncy, milk filled udder and fat, clapping butt cheeks. Big Macintosh couldn't take it anymore. He got to his hooves and walked behind Fluttershy, drinking in her every curve and jiggle. “Who's a good cow?” He asked.

 

“Hmm?” Fluttershy moaned.

 

“Who is a good, fat, sexy cow full of milk?” Big Macintosh grunted as he stepped over Fluttershy. Even with her recent changes, Big Macintosh still towered over her. She could feel his breath on the back of her neck...and his erection pressing against her ass.

 

“M...M...Me? Is it....is it me??” Fluttershy whimpered.

 

“Yes it is. Who's my good, milky cow slut?” Big Macintosh asked.

 

“Oh please...please let it be me. I...need your help in a different way, Big Mac. I need to be bred. Please...”

 

“Beg.” He commanded.

 

“PLEASE! OH GOSH PLEASE! RUT ME! BREED ME! FILL ME WITH LITTLE COW BABIES TO DRINK UP ALL MY MILK!” Fluttershy screamed like the world was ending.

 

It was too much. Big Macintosh bit onto Fluttershy's ear and thrust himself forward. He was true to his name, big in every way. No amount of soft, wobbly Fluttershy butt was going to stop his hard erection from plunging deep into her wet pussy. Fluttershy screamed again, slumping back into the pile of hay.

 

Big Macintosh smiled. It was always a massive ego boost when mares collapsed after the first thrust. Still, there was a need to release. Slowly, he pulled himself out and then gave a much calmer, gentle thrust. Fluttershy moaned again, doing her best to push her butt into his crotch.

 

“Still want more? Need it, don't ya? Big, fat cow wanna get even fatter off being pregnant?” Big Macintosh teased with another thrust.

 

“My body....screaming for it....please.” Fluttershy moaned again.

 

Another thrust. “Slutty little cow. Letting her body rule her like this. Submitting to me like this. Ah'll keep your secret safe for sure so I can keep fucking you like a breeding animal...”

 

Another moan. Big Macintosh could feel Fluttershy gripping his cock hard. It was trying to milk him just as much as he milked her. He thrust again and again, filling the air with the wet slaps of his crotch against Fluttershy's rear and Fluttershy moaning and screaming.

 

He was getting close. The urge to bust and impregnate the mare under him was immense but it felt like a waste. There was something much more deserving of his attention. Big Macintosh slowly pulled out of Fluttershy's pussy and used his might to tip her onto her back.

 

“Wh...Wha?” Fluttershy didn't have time to adjust as Big Macintosh shoved his cock on top of her udder and squeezed it around his dick. Fluttershy went limp as milk sprayed everywhere, releasing more of the pent up pressure that had been building up with each thrust.

 

Big Macintosh grinned as he resumed thrusting. Even as bloated and tight as it was, Fluttershy's udder was easy enough to wrap around his cock. An extra hole to please himself and pleasing it was. There was no holding back now. Big Macintosh grunted hard as he came, splattering Fluttershy's fat tummy and her huge udder with cum.

 

“There...you're my cow, now. My sexy, jiggly, milky mare slut.” Big Macintosh huffed. He let himself rest for a few moment before getting up from the barn floor. “Be a good slut and stay here for now. Ah'll come back with some more hay later and give you those foals Ah promised.”

 

The moon was high in the sky. Everypony in Ponyville was fast asleep. All but one red stallion. He rolled another bale of hay towards the abandoned barn in the moonlight with a big smile on his face.

 

“Good evening, lil missy. Ready for your breeding?” Big Macintosh asked.

 

Fluttershy didn't need to be asked twice. She raised her tail and spread her legs, doing her best to adjust for the massive udder still growing between your legs. “Aw, need some help with that before we start?”

 

He leaned down and kissed the tight, milky orb. Fluttershy tensed up as his lips graced her udder again and again. She was already moaning again and her arousal was filling the barn once more. It didn't take long for a small shudder to ripple through Fluttershy as her milk began to leak and flow once more.

 

“Good cow. Now...those foals Ah promised.” Big Macintosh grinned as he stood over Fluttershy again. She was totally submissive to his whims, backing up her soft rear and squishing it against his crotch.

 

“Please...last time was such a tease. I wont let you leave here unless you impregnate me tonight...” Fluttershy begged.

 

She got her wish. Big Macintosh pushed forward and entered her again. The instant climax increased the flow of milk, making a gigantic puddle on the floor. Big Macintosh didn't waste any time, pushing and pumping and thrusting his fertile cock deep into Fluttershy's pussy.

 

“Who's a good, pregnant cow?” Big Macintosh asked.

 

“M-ME!” Fluttershy screamed.

 

“Who's gonna be my big, pregnant, milky slut?” Big Macintosh asked.

 

“ME!” Fluttershy replied.

 

“Then have all the foals you could ever want!” Big Macintosh hurried his thrusts and pushed as deep as he could go. Both ponies moaned hard as they climaxed together. Fluttershy's knees went weak as she could feel Big Mac's warmth deep in her body.

 

“Apple family are good breeders.” Big Macintosh huffed as he slowly pulled out. “If ya ain't pregnant already, wont take long.”

 

“Yes....yes...please...” Fluttershy huffed. She could feel his seed leaking out of her but it didn't matter. She knew. She was going to be the biggest, bestest cow anypony could ever ask for.
