Chapter 2: Big Mac Goes out on the Town

Big Macintosh was sitting on his bed with the thick diaper between his legs blushing a little. All the while his sister was walking back and forth grumbling and growling under her breath. “I can't believe that you're acting like a little foal! This must be the work of the curse Twilight was going on about.”

The big stallion chuckled and shrugged. “I mean yeah it could be just that...I’m not sure I just felt like putting on diapers one day and just kept on doing it. It helps me relax after a long day at work."

Applejack shook her head and poked the diaper with a hoof. “We really need ta get this under control. The last thing ya need is somepony seeing ya in this.”

He crossed his hooves and scoffed, “I wouldn’t just do that! Heck, I was hidin’ it from ya because I know ya wouldn't understand.”

Applejack turned around and asked. “It’s one thing if ya was doing this and ya just trying to relax in your own way. But if your hearing voices in your head then we need ta get ya to Twilight as soon as possible.”

Big Macintosh stomped a hoof and growled, “ya dun need to do anything like that! I ain’t no little foal, and I really don’t need Twilight’s magic for nothin’.”

Applejack stomped her hoof back and groaned, “ugh you're more stubborn than a mule and that's coming from me! I’m gonna go grab Twilight, and she’s going to fix you up or so help me I’m gonna buck you!”

The angry farm mare then went out and slammed the door behind her while Big Mac pouted and brooded sitting on his bed with hooves crossed over his chest looking down at the mass of white padding that poofed between his thighs. The voice then entered his head, that’s right how about we go and show off you're a big colt, and you don’t need Applejack!”

Big Mac stood up and ruffled his big diaper. “That’s right I’m not scared of anypony! I’m going to show off my diaper!”

The voice whispered, yes that’s right you go show off that big thick diaper of yours it’s super adorable.

Big Mac blushed he was never called adorable and to be honest it felt kind of cute. He stood up with his back hooves spread out by the thick padding and waddled off down the stairs with a considerable strut. He continued to wiggle through the house with a thick diaper shaking about making a loud rustling noise from the diaper. He poked through the door and opened up to Ponyville. Big Mac whimpered a little, and he could feel his hooves shaking, but the voice entered into his mind, don’t be scared you love diapers and everypony will see that now go out there and show the world how adorable you are!

Big Macintosh wiggled out of the house and went into the streets shaking his big padded rump proudly with his thick diaper shaking back and forth. Ponies all overlooked with awe and confusion at the giant red stallion strutting around in a thick diaper. Many ponies whispered and pointed at Big Mac seeing that Applejack acted odd only a few months earlier. Many were whispering if that something was happening to the Apple family. But the happy stallion seemed to not care at the strange looks and was actually enjoying the attention waving a hoof at the ponies as he walked by. The voice continued to enter his mind, aww look at you waddling proudly in diapers your like a three-year-old.

He blushed as he whispered, 'three..yeah...I don’t have a lot of memories from that age...I...in fact I wouldn’t mind reliving those years just so I can have memories of them."

The voice persisted and cooed, “yes I bet you would now let go and relax ease that big pony mind of yours. Remember when you didn't have any responsibility when all you knew was the love of ponies taking care of you. Remember how proud you are of that big diaper your wearing.”

Big Macintosh smirked and wiggled his diapered tush. “Yeah, I love diapers especially these ones keeping my rump warm and keeping me from going potty on the floor.” He squeaked out loud hearing himself say potty like a toddler.

The voice whispered in his head, ”that’s right you are only three years old after all.”

Big Macintosh thought for a second plopping down on his thick diaper…three…was he really only three years old?

He looked down at his diaper and thought to himself, but by three I wasn’t fully toilet trained?”

The voice laughed, guess not, seems your still in diapers little toddler.

Big Mac squealed as he jumped up and down in the middle of town shouting, “yeah I’m a toddler who loves his diapers!”

He didn’t notice right away that everypony in the vicinity was now staring at him with confusion. Some smirked and chuckled at the stallion’s antics, most though were concerned watching the well known stallion acting in such a odd way. He stopped bouncing and looked around at the crowd of ponies and waved a hoof and babbled. “Hello, I Big Mac and I three years old? Can somepony help me find my big sissy Apple Bloom?”

As Big Mac was acting a like a toddler in front of everypony in Ponyville. Applejack was walking back and forth in Twilight’s library where the purple unicorn sat on a desk taking notes and studying a book on possession and spirits. All the while Applejack continued to explain to her friend regarding her brother. “So yeah what I’m trying to say is that think I figured out that the spirit you were talking about the one that possessed me, I’m sure it possessed my brother.”

Twilight closed a book she was reading and looked up at her friend with a concerned look and asked, “I need more details what’s it doing to him exactly?”

Applejack turned with an angry glare. “I told you he’s acting like a big baby! He’s wearing diapers and drinking out of a big foal bottle. Heck, I think he’s playing with some old rag doll.”

Twilight gave the nod and whispered, ”the spirit must have used the doll as a medium this time...do you have details on the doll?”

Applejack growled under her breath. “Well it’s your doll, it’s the one you put a "want it need it" spell on driving half of Ponyville crazy.”

Twilight cringed as the memories of that incident which were still raw. She turned around with a sheepish smile. “I’m so sorry, I’ll get to him right away, he’s still at your house right?”

Applejack gave a nod but nervously scratched the back of her head as she explained, ”yeah he’s uh a bit upset about how I burst in on his private time.”

Twilight got up slowly and whispered with tension in her voice. “Oh dear, well hopefully he isn’t too upset about everything. I’ll just explain things, and hopefully, we can get him to reject the spirit before it makes him do anything thats embarrassing.”

Applejack rolled her eyes and scoffed at the notion. ”There’s no way he would walk outside in diapers. I mean heck even if he likes wearing them there’s no way he would do that in public.”

Big Macintosh was proudly bouncing up and down in his diaper giggling like a little foal. All the while ponies were laughing him. Big Mac continued bouncing and shaking his diaper thinking they were liking his little show. Luckily, a reluctant Cheerilee who was out getting some school supplies for her students came forth from the crowd and asked in a sweet but concerned tone, ”hey Big Mac what’s wrong why are you acting like this?”

The big red-coated stallion stopped bouncing in his diaper and raised his hooves in the air and exclaimed. “I’m a big baby. I’m just super happy because of my new diapees!”

Cheerilee sighed seeing that Applejack acted the same way not too long ago and thought to herself. Apple Bloom is having a hard time dealing with her sister this way not to long ago. This is too much for one young filly. Cheerilee came up and sweetly cooed, ”look, sweetie, we need you to go and get some help now come on.”

Big Mac got up and waddled after Cheerilee with two big innocent puppy dog eyes he asked, ”are we going to my big sister Apple Bloom?”

Cheerilee shook her head and explained, “No not right now she’s at school, we can visit her later.”

Big Macintosh shook his head and stomped his hooves, “no! I wana see her now!”

Cheerilee scolded him as a mother would to a disrespectful foal. “No Big Mac, you listen or...no ice cream got it?”

Big Mac’s ears perked up at Ice cream and started to jump up and down with his diaper bouncing along with him shouting, “I want ice cream! I want ice cream!”

Cheerilee looked around seeing many ponies bursting into fits of laughter. Cheerilee gave a big sigh and whispered, “okay Big Mac we’ll get ice cream after we see Twilight okay?”

Big Macintosh stopped bouncing and nodded, ”otay Cheerilee I go see Twily.” She then led him off towards Golden oaks library watching his giant diaper bouncing up and down. Cheerilee just gulped and nervously whispered, “hopefully she’s not to busy. ”

But as they passed the schoolhouse Big Macintosh’s face lit up and he shouted, “Apple Bloom is over there! I wana go say hi!” He sped off towards the school as Cheerilee ran after him and shouted, ”hey Big Mac stop!”

But he didn’t listen with his foalish instincts wanting to see his big sister Applebloom. He burst into the schoolhouse. But as he did so every student in the classroom looked up from the test they were taking and stared at the big hulking padded stallion. Some of the students burst into fits of laughter as Big Mac whimpered scrunching his diaper with his back legs. Then out of nowhere a loud hissing noise echoed throughout the classroom. The stallion squealed feeling the hot urine flow into the innereds of the padding. He scrunched his diaper with his back lges again but this time the soggy padding made a loud squelching noise as he pressed his legs together. Every foal in the classroom all roared with laughter at the stallion who just peed his diaper. Big Mac started to tear up and whined, "Apple Bloom I pee pee in my diaper need a change."

The class was stunned, and Apple Bloom was just mortified at what she was seeing. She already had to deal with the fact her sister acted like a filly a few months ago, and now her brother is acting like a big foal.

Apple Bloom slowly got up from her desk and whispered, “look uh Big Mac this isn’t a good time I’m taking a test.”

He shakes his head and stomps around "I need a change from my big sissy and My name, not Big Mac, it's Baby Mac."

Every foal in the classroom was now on the floor doubled over from laughing as Apple Bloom shoved her hooves over her eyes. "My life...it’s over..."

Cheerilee finally entered the classroom and stomped a hoof then shouted, “that’s enough!”

Everypony stopped laughing instantly as the teacher strolled to Apple Bloom and whispered, “I’m so sorry I tried to stop him.”

Apple Bloom looked down with embarrassment and shame. She slowly got up from her desk and trotted over as she sighed, “it’s alright, I’ll take him home if that’s okay.”

Cheerilee nodded and whispered, “you can take the test tomorrow. Go on and help your brother.” Apple Bloom went over to her brother and grumbled, “come on...uh Baby Mac let’s get you changed.”

He smiled and trotted off behind his sister proudly shaking his thick diapered rump back and forth.

Chapter 3: Applejack's Trip to the Diaper shop

Applejack was casually waking the street when she heard about how cute Big Macintosh looked wearing a diaper. This made her ears perk up as she looked around hearing more gossip from many ponies giving her odd looks and whispering amongst each other. The farm mare paused with fear printed on her face. She gulped and whispered, “no...no way...he didn’t!”

She rushed down the street and then she came upon a dispersing crowd with many ponies still talking about the big padded stallion showing his diaper off not a few moments earlier. Roseluck came over and asked, “hey Applejack is Big Mac okay? He was wearing a diaper and showing it off to everypony not too long ago.”

Applejack’s ears drooped behind her head, and her face went blanche, and she stammered, “N...n..no way...he..he wouldn’t.”

Roseluck waved a hoof in front of Applejack’s face and asked in a sarcastic tone. “Hello, anypony home?”

The farm mare shook her head and shouted, “I need to find her where is he!”

Roseluck blushed and answered, “well...I saw Apple Bloom leading him away to your house not too long ago.”

Applejack ran off down the road as she thought to herself, he better be there I need to find him and stop this curse before it’s too late!”

Applejack burst through her front door to find Big Macintosh laying down on the ground legs raised in the air with his giant thick diaper poofed outwards. Apple Bloom was standing over him as she was going to start the diaper change as she looked up and asked, “hey Applejack can you do this I’m not really sure uh...how…”

Applejack was steamed as she stomped over and looked down at the padded stallion and shouted, “So you decided to go out on the town and showed your diapered rump to everypony huh!?”

Big Macintosh looked at her with an apologetic look and whimpered, “sorry Applejack, I didn’t know I was going to get in trouble.”

Applejack just rubbed a hoof down her face and grumbled knowing that the curse has now entirely taken her brother. “Fine, I’ll change your diaper.” She came over and began to unstrap the large green tabs and unfolded the soggy diaper and began to wipe down his front. Big Mac’s ears were still bent down with an apologetic look he whimpered, “Applejack are you mad at me?”

The farm mare looked up at the big stallion seeing the innocent look in his eyes. Applejack sighed seeing that and shook her head. “No, I’m not angry at you.”

Applejack continued the diaper change grudgingly and as she made sure to finish wiping Big Mac’s rump up. She got out the bottle of foal powder and began to powder the rumps crotch and rump areas. The mare rubbed the powder into her brother’s fur and continued to strap a substantial thick diaper around him and sighed, “ugh this is so gross.”

She slapped the two tabs around her rump and made sure they were snug and assisted him up. “Well at least that’s done, now we can focus on getting you cured mister.”

He plopped on his padded rump and pouted as he asked, “cure? Does that mean I need to go to the doctors?”

Applejack came over and nuzzled him. “No, you don't need to go to the doctors. That’s just um...big pony stuff you don’t need to worry about that.” He was still unsure and persisted. “But Applejack are you sure your I’m okay?”

She gave his padded rump a few pats and cooed, “yeah you’re fine so don’t worry about a thing.” she then turned to her little sister and asked, “Apple Bloom, please take him upstairs…” Apple Bloom grumbled under her breath as she leads her big brother by the hoof upstairs. Applejack groaned rubbing a hoof down her face. “What do I do?”

The great big baby was now upstairs playing patty cake with Apple Bloom. While Applejack walked back and forth impatiently. Twilight eventually came down seeing the disturbing yet adorable scene with wide eyes. Applejack turned around and read Twilight’s expression of disbelief and exclaimed. “see what I mean he’s clearly possessed. So now we need to help him learn he’s a big pony right?”

Twilight nodded “yeah that’s it, but you still need to care for him while he’s like this.”

Applejack shouted in frustration, “Are you kidding me!? He’s freaking huge! How in the hay am I going to find foal supplies at his size!”

Twilight Sparkle rubbed a hoof over her head. “Well, we really don’t have any other choice.”

Applejack stomped a hoof and shouted, “But how am I supposed to care for Big Mac! He’s so bucking big!”

Twilight shook her head unable to give a right answer and shrugged, “well …I know of a place, but you can’t tell any pony about this.”

Applejack eyed her as Twilight took a deep breath and continued, “look after the curse affected Spike he still always had a need for wearing diapers at night. So I found about the baby store here in Ponyville and found out they...um also sell adult foal stuff…”

Applejack gulped and whispered, “Seriously?”

Twilight nodded as Applejack eyed her friend. “You better not being wearing diapers too.” The purple coated mare gave a sheepish smile. “What no! Of course not!”

Applejack just turned away in a blunt. “Fine whatever but can you stay and watch Big Mac while I’m out?”

Twilight turned around with a blush and explained, “You have no idea where the store is.”

Applejack shook her head and grumbled, “Well you have no idea what Big Mac’s sizes are or what he liked as a foal.”

Twilight tapped a hoof on her chin and asked, “what about Granny Smith is she here?”

Applejack shook her head and grumbled in an irritated tone. “She’s down in Appleloosa for the week.”

They both gulped knowing the only pony available to watch Big Mac was Apple Bloom.

Apple Bloom wasn’t really listening as Applejack was trying to explain that she needed to watch Big Mac for a little bit. The filly just rubbed a hoof down her face and grumbled, “ugh! You know I can’t change his diaper right!?”

Applejack gave the nod as she continued to explain, “of course I know Sugarcube we’ll only be gone for an hour at max. I’m sure he won’t be able to soak one of the giant diapers before we get back.”
Apple Bloom ground a hoof into the ground unsure of what to say.

Applejack sighed as she rubbed her little sister’s mane and cooed, “Trust me you're going to be fine.”

Apple Bloom irritated as she threw her sister’s hoof from her mane and shouted,“Fine, I’ll do it! But you're going to owe me big time for this!"

Applejack snickered, “alright big sis, I’m counting on ya.” Twilight and Applejack both strode through the front door. Apple Bloom just watched with unsure expression until she heard Big Mac’s diaper crinkling down the stairs. She turned around to see Big Macintosh with his cute confused expression as he asked, “Apple Bloom can we play Checkers again?”

Apple Bloom gave her big brother a loving smile. “Alright come on you big baby.” She ran upstairs as Big Mac laughed and ran after her.

While Apple Bloom was caring for Big Mac Twilight and Applejack continued their walk through Ponyville Applejack wore a blue mare’s bonnet and a pair of sunglasses as she towards the ground trying to avoid eye contact any ponies. The two eventually came upon the foal shop that Twilight mentioned. They looked upon a small quaint shop that read “Paddy’s Diaper Shop” with a big pacifier printed over the words. Both mares blushed and slowly walked in and saw rows upon rows of foal items stacked in shelves that stretched out for what seemed for miles. Applejack was surprised and astonished seeing that how big the place looked on the inside did not match what she saw on the outside. The farm mare just stared down the aisles in disbelief. As she slowly removed her sunglasses, the mare whispered, “ho…how can a store like this be here, and I never noticed?”

Twilight just shook her head still embarrassed as she explained, “Most ponies don’t come here unless their parents or…”

Before she could finish A happy bouncy light yellow coated mare with a swirly light green mane, and tail hopped over and chirped, “hello I’m Paddy Paddington! Welcome to Paddy’s diaper shop!”

Both mares stood there with blank expressions at the mare’s cutie mark which was a pacifier with a blue mouth guard cutie mark printed on Paddy’s rump. The mare looked over with a pair of cute pink eyes bounced over and chirped. “you two you must be Twilight! Spike talks about you all the time! You must be Big Mac’s little sister Applejack.”

Applejack nodded with a sheepish blush and whispered, “So…you’re the one he buys his diapers from?”

Paddy gave a bug smile and proclaimed, “yeah he’s one of my favorite customers.”

Applejack sighed, “Yeah, well he’s now thinking he’s just a big foal thanks to Twilight’s doll Smarty Pants.”

The mare blinked as Twilight rubbed her mane and whispered, “Yeah it’s true, and it’s the reason why Spike likes wearing diapers at night.”

Paddy put a hoof over her mouth and giggled, “well it sounds like you’re going to need those big diapers his order.”

They both blushed and stumbled a little unsure of what to say, and the mare waved a hoof. “Come on, and let’s pick out diapers for the big guy.” She bounced down the aisles the the extra large diapers and took one.” These are the ones he usually orders.”

She throws them at the Applejack who squeaked at how big it was and shouted, “they're huge! Why would you make these?”

Paddy just waves a hoof and laughed, “we normally don’t, we have to custom make them he is such a big silly foal.” She then got out a basket and started to place the foal powder and cream into the basket with giant’s onesies and oversized toddler overalls. “There you go this is everything.”

Applejack grudgingly took the giant pink diaper bag and strapped it around her shoulder and gave a long exasperated sigh. “I can’t take all this without paying for them.”

Pady smirked and waved hoof. “Oh it’s fine, I’ll put it on Big Mac’s tab, besides I have a feeling he’s going to enjoy this...also Twilight your order of happy love di-“

Twilight’s face grew with a deep blush as she shouted, “okay thank you let’s go!”

As he purple coated Unicron ran out of the store. Applejack shook her head and sighed, “I wonder how many of my friends secretly like diapers?”

As Applejack was coming back from the store with her giant pink diaper bag, wearing her blue bonnet back on and sunglasses placed over her eyes. Many ponies gave the farm mare odd glances, and some whispered behind their hooves. Applejack blushed and lowered her head trying to avoid the curious glances from the ponies. Twilight bent near her sister's ear and whispered, “yeah I know how you feel just keep going werealmost home."

Applejack gave a slight nod as they sneaked through the town heading straight for the farm house. But what came bounding down the road made her stay in place seeing her big brother running down the street in his huge diaper shaking back and forth like a giant white thick ball made of padding. The big stallion continued to run despite the thick padding strapped around his legs she shouted, “big sissy can you change my diapee!”

Applejack just watched with a blank expression filled with embarrassment Big Macintosh slammed into Applejack with her bonnet and sunglasses flying off revealing her identity to the world. Just as the packages of diapers tumbled out all over the ground. The farm mare just sat there stunned as ponies all over burst into fits of laughter. Applejack wanted to bury herself under a rock, but she slowed her pride as she slowly got up gathered the packages of diapers into the diaper bag and strapped it around her. Big Mac’s ears flattened to the side of his head as he apologized, “I’m sorry Applejack, am I in trouble?”

Applejack just focused her attention on her big brother despite the laughter she took Big Mac by the hoof and mumbled, “come on let’s get you changed.”

She then leads him off as he looked around at the laughing ponies and shouted in childish glee, “they all happy cause I'm in diapers huh!?” Both Twilight and Applejack looked at each other with worried expressions realising get Big Mac to reisist the power of the spirit is going to be more difficult than they originally first thought.

chapter 4: Baby Mac tries Applebucking

Applejack grudgingly took Big Mac through Ponyville as the big stallion had his lowered, and was whimpering thinking that he was in trouble. But Applejack continued though trying just to get back to her house as soon as possible without any more publicity. At this point Applejack could feel the eyes of everypony in the vincinity watching her lead the diapered Big Mac back to their farm. She eventually got to her home and saw Apple Bloom running towards her with a worried look and upon seeing her big sister she started to stammer, “ I’m so sorry Applejack I tried to explain that we needed to wait for his diaper change. But he was insistent that he wanted one then he just ran off before I could stop him!”

Applejack just gave an exasperated sigh and placed a diaper bag near the front door as she explained, “it’s not your fault, I think that I put a little too much burden on your shoulders.”

The big stallion whined as he shuffled in his hooves looking around the house nervously. Applejack looked over at the stallion and patted his mane and nuzzled him. “Hey, I told you it’s alright I’m not mad at you.”

The Big stallion gave his sister a smile and hugged his sister as she pushed him away a little seeing his hooves were covered in drool. Applejack shook her head and grumbled. “Alright well, as long as Big Mac is like this you and I need to care for him. Now you go along and go back to school I’ll watch him while I do the applebucking.”

Apple Bloom gulped as she turned around with a worried look on her face and saw Big Macintosh sucking his hoof looking around with his big wide green eyes. The little filly turned towards Applejack and asked, ”ya sure ya can to do this? I know it’s been a while since you cared for me like a foal.”

Applejack shook her head and explained, “Nope, you need to go to school I can take care of Big Mac.”

Apple Bloom just shrugged and exclaimed, “alright, but if things get too out of hoof ya call me big sis.”

The farm mare gave another eye roll and scoffed, “sugarcube, the second I need help from you will be the day I eat my own hat.”

Apple Bloom burst into laughter at the thought of Applejack eating her hat and exclaimed, “oh yeah! Ya wana make that bet!”

Applejack smirked, ”as if, I would never eat my hat it’s just a figure of speech. Now ya get going before ya miss your test.”

Her little sister grumbled as she slowly walked out and slammed the door behind her. After Apple Bloom grudgingly away from the house. Applejack turned to her big brother with a hoof in his mouth with a puddle of drool now forming on the ground. She looked down and asked, “now, for you, I have to take you with me while I do some applebucking. So I need to put ya into your overalls.”

The big foal clapped his hooves in joy, “Yay! I wana buck apples too!”

Applejack rolled her eyes as she took out the overalls and looked over at her brother and gulped as she explained, “now Big Mac it's time for your diaper change."

The Stallion whimpered but he slowly laid onto the ground with all four hooves now in the air revealing his giant white diaper with the huge yellow stain on the front of it with the little green apples printed on the fabric were faded. The farm mare groaned as she started the change and slowly unstrapped the straps around the landing zone and gagged at the smell of urine that wafted from the diaper. Big Mac whimpered some more making Applejack give her brother a smile before he could cry and cooed, "hey it's okay, don't worry I can do this."

The farm mare took a deep breath and first started with taking out the foal wipes and began to clean Big Mac's crotch area first. As she wiped her brother down he kicked his back legs now and again but he seemed fine with his sister doing the diaper change. Applejack finished up bawling the sodden diaper with the wipes inside and tossed it away as she exclaimed, "well that was nasty but I've dealt with worse. Now onto the easy part."

The farm mare then took out a giant blue bottle of foal powder and clean diapers and began to powder the crotch area and rump of her brother smoothing the powder all over making the stallion giggle and kick about. Applejack looked up and cooed, "aww glad ya having some fun Big Mac now it's time for a new fresh diaper."

She unfolded the diaper square slowly and with some difficulty lifter her big brother's rump and slid the padding underneath. After some adjustments, she folded the front of the diaper over his underbelly making sure to tape the tabs firmly onto the landing zone.

The farm mare then wiped the sweat from her brow and exclaimed, "there your all clean, now I need to get your overalls on ya." She then took the giant adult-sized overalls from the diaper bag and turned to her brother who was pressing a hoof into his diaper with udder bewilderment. Applejack coughed making him look up as she asked, "Uh, Big Mac can ya raise your hooves please.”

Big Mac squealed and rose his front hooves with glee. Applejack just slowly continued to dress the stallion into the toddler like overalls and had some trouble with the button hatch trying to snap the buttons together over the mass of white padding. The diaper was thick making it difficult to snap the hatch together. But after some struggling, she managed to snap the buttons together. Applejack lifted the stallion up just as the stud watched with his huge innocent eyes filled with delight seeing the thick white diaper strapped around his rump. Applejack looked at her big brother looking like some oversized toddler with the huge diaper bulge showing through his overalls. She couldn’t help but blush and whisper. “He is rather cute though. I wish I could’ve seen him as an actual baby.”

Big Mac looked up at his sister with his ears folded back with an innocent smile and asked in a sweet tone, “can we go applebucking now?”

Applejack blushed lowering her hat over her face and cooed, “of course sugarcube, I bet you're going to love being the baby of the house now.”

The stallion giggled in delight as he bounced upwards shaking his padded his rump covered with his blue overalls crinkling and crackling as he exclaimed in joy, “Yeah I a big baby!”

Applejack chuckled a little then took Big Macintosh's hoof. "Come on sugarcube, I need to get to applebucking." The farm mare then led the excited Big Mac towards the apple orchard.

Big Mac had a big smile on his face as he waddled out to the apple orchard. Applejack laid down a giant baby quilt and gave him a few giant foam blocks to play with as she explained, “now you play with your foam blocks while I buck apples.”

The stallion gave the nod and took one and began to chew on it as Applejack started to buck apples as Big Mac just slammed the foam blocks together babbling incoherently. He looked over at Applejack for a while seeing her work, and he got up to one of the apple trees and started to slam her back hooves against a tree. The stallion giggled seeing the apples falling he continued slamming his hooves into the tree laughing in joy until the trunk snapped and the wood splintered and cracked. The tree then crashed to the ground with a loud boom making Applejack turned around upon hearing the crash. She saw Big Mac whimpering as he slowly walking backwards with his ears lowered as the oversized foal whined. “Applejack I sowie I didn’t mean ta do that.”

The mare looked upon the fallen apple tree and rubbed a hoof down her face as she groaned. “Big Mac I told ya, to just Just play with your toys okay.”

Big Macintosh pouted with his ears folded back and whined, “but...I wana help?”

Applejack turned to the destroyed apple tree and pondered as she tapped a hoof to her chin. “He’s a big baby trapped in an adult’s body...but...When I applebucked, it helped me stop the curse.”

She turned to Big Mac and cooed, “okay Baby Mac, you can help me buck apples. But I need to supervise still what you do.”

The stallion squealed in delight bouncing around the orchard causing the ground to tremble. Applejack shaking about stammered, “Baby Mac stop that!”

Big Macintosh stopped instantly as he turned around with a look not unlike a scared colt who just wet the bed and whimpered, “sowie Big sissy I got too excited.”

The stallion nodded as he came over to another tree and positioned himself getting ready to buck it with all his might. But Applejack quickly ran over to her brother and exclaimed with a nervous tone. “No, don’t buck unless I tell you too.”

He gave a nod and waited paitently as Applejack paused again as she thought to herself, ”good you still have some notion of what to do before.” Applejack then helped Big Mac position his front legs first then she moved to the back legs and adjusted them. She cringed as she touched the diaper bulge hearing it crinkle beneath her hooves. Applejack then made sure the back hooves were planted and when finished Applejack cooed, “good, now hold this position buck those hooves like this.”

She began to buck the tree and explained, “you need to hit it hard but only to take the apples off not too hard to destroy the tree."

Big Mac continued to help buck again hitting the tree again, but despite him being more cautious it was still a little too hard. Suddenly a bunch of apples began to rain down on top of him. The big stallion covered his head with his forehooves. But one rouge apple bonked right onto his hooves making the stallion shriek just as a few more apples fell onto his head. The stallion began to whimper and wailed as he ran off just as Applejack squeaked “hey Big Mac! Don’t go running back into Ponyville!”

Apple Bloom was standing outside of the house still unsure if Applejack could care for Big Macintosh by herself. “I know I messed up earlier, but Big Mac is a full grown stallion acting like a baby. Applejack is gonna need all the help she can get right now.”

But as she was lost in thought, as Big Mac came down the road crying and wailing. Upon seeing his little sister he hugged Apple Bloom with his hooves and held her close to his chest as he exclaimed, “Abble Boom I gots booboos on my head!”

Apple Bloom blushed and squeaked, “uh okay calm down and let me help you.”

The stallion theb slowly placed the filly on the ground as Apple Bloom took her big brother by the hoof and cooed, “come on how about we get you back inside.”

He nodded as she leads him onto a couch as she took out some big green band-aids and strapped one on his head and one on his hoof. She then paused noticing his injuries were very minor and thought, I know there was one thing Applejack did to calm me down when I was younger. “ The thought came into her mind as the school filly kissed the bruises on his hoof and head. “There a kiss on your booboos."

He smiled and hugged his sister to his chest again. “Thanks, big sissy! I’m feeling better already.”

Apple Bloom groaned but let the Big stallion embarrassed her seeing he was calming down. Applejack ran into the room about the same time. She saw Big Mac with the big bandaids on his forehead and hoof she slammed a hoof to her face. “Ugh! He only had some small bruises! How could he be acting like this!?”

Apple Bloom led him off the couch and explained, “ya know that babies take silly stuff like that more serious. Don’t you remember? I used to cry every time I lost my bow.”

Applejack turned to Big Mac who was now forgetting about his “boo-boos” and was more concerned with bouncing around in his diaper giggling as Applejack sighed, “well I guess applebucking isn't the key then what is!?”

Apple Bloom shrugged, “I don’t know, but I’m sure we’ll figure it out eventually. Both you and Spike broke the curse somehow.”

Applejack stomped a hoof in frustration and shouted, ”so what am I supposed to do in the meantime! Granny Smith is going to be gone for the rest of the week! We're in the middle of the Applebucking season, and ya still need to go to school!

Apple Bloom pondered the question watching Big Mac waddle around with a determined look on his face. So, we need a babysitter, but who the hay would want to take care of a fully grown stallion. The thought then came into her mind as she turned around and explained, “You know what I think!? We can ask Fluttershy to babysit!”

Chapter 5: Babysitting Baby Big Mac begins!

Fluttershy was humming as she was busy caring for her bunnies seeing them nestling with each other. She sighed “well it looks like all the baby bunnies have their burrows. But, now I have the rest of the day to do…well…something.”

The yellow Pegasus pondered what she will do for the rest of the day when out of nowhere Derpy Whooves of all ponies crashed down freaking the bunnies out making them bounce off a Fluttershy shook in terror hiding underneath her wings. Derpy slowly got up wobbling back and forth she then oriented herself shaking her head and hoofing a letter to Fluttershy as she explained, “hey Fluttershy sorry for the crash, I have an urgent letter from Applejack.”

Fluttershy was confused but to the letter and read it out loud.

Dear Fluttershy,

This is Applejack, and I’m sure your busy and all roundin’ up the baby bunnies. But this is urgent! Big Mac got himself acting like a big foal, and I need you to foal-sit while I try finishing up the applebucking. Please come by sweet apple acres as soon as possible.

Fluttershy blinked as she recalled some ponies talking about how Big Macintosh was acting oddly with wearing diapers acting like a big foal. She just whispered to herself, “so the rumors were true about Big Mac I hope he’s doing okay.”

The yellow Pegasus stored the letter away and exclaimed, “well I need to get to Sweet Apple acres as soon as possible. She instantly got up and fluttered off toward the farm as fast as her gentle wings would carry her. She fluttered for some time with a confused look on her face unsure of how to take the message she received from Applejack. It made her unsure of how to take the information. I have a lot of experience babysitting now considering I have foal sat the cutie mark crusaders and Spike. I’m sure Big Mac can’t be any more difficult. While lost in thought she squeaked coming short of hitting Applejack’s house and gasped in relief as she fluttered gently onto the porch. The nervous yellow Pegasus stood near the door hearing loud booms Big Mac laughing like a colt, and Applejack shouting. Fluttershy stood there sweating unsure if she should answer and slowly knocked on the door and whispered, “hello Applejack? I uh got your message.”

Upon hearing her Applejack opened the door with her straw yellow mane looking like a mess and her face had a look of being worn out with twitchy eyes and stains all over her coat. The farm mare instantly gave a sigh of relief upon seeing the yellow Pegasus and exclaimed, “thank Celestia you’re here! I was beginning to worry you wouldn’t show up.”

Fluttershy still quivering looked over her friend’s shoulder at the big foal and asked, “so um…how is Big Mac is he okay?”

The farm mare scoffed as she explained, “no, he’s far from okay!” She waved a hoof, and Fluttershy cautiously walked into the house and saw Big Mac sitting in the center of the living room in nothing but a clean diaper with the green apples printed on them for wetness indicators while he was playing with the giant foam blocks. The big foal was stacking them on top of each other only to knock them down with a foolish laugh clapping his hooves. Fluttershy dawwed at the scene and rushed over to cuddle the big baby as she exclaimed with glee. “Oh, he’s adorable! he was just like Spike when he was under that odd curse.”

Applejack just fixed her hat and explained, “yeah Big Mac’s kind of cute and all, but he is a hooful. Uh… thanks for coming out here on short notice. I hope this isn’t to much trouble.

Fluttershy who was pinching Big Mac’s cheeks and patting his thick diaper feeling nostalgia upon hearing the diaper crinkle. Fluttershy barely heard Applejack as she turned around and casually waved a hoof. “oh don’t worry this is a wonderful break from trying to round up a bunch of baby bunnies.”

Applejack gave another sigh of relief before she started a lecture on Big Mac’s needs. “Well, I know ya have experience with foals before, so I’ll go over the basics for a refresher. Big Mac here is just like any other baby, change his diapers, feed him bottles when he’s hungry, most importantly make sure he stays inside the house and out of trouble while I’m applebucking.”

Fluttershy snickered seeing how that’s the same rules for every foal she cared for that was still in diapers. The mare just sweetly replied, “oh that doesn’t sound too bad, I think I can manage.”

Applejack still concerned and unsure of leaving Big Mac alone continued to explain. “Just make sure he doesn’t do any bucking, and if ya need anything, I’ll be outside just given a holler.”

Fluttershy nodded and replied back, “of course, I’ll keep that in mind. Now you go along I got things here.”

Applejack started to slowly walk away taking a few glances back as she was still nervous. But seeing Fluttershy help Big Mac stack his blocks and keeping him engaged made her smile as she confidently walked out of the house and to the Apple family’s apple orchard. Fluttershy seeing that Applejack was finally gone turned to her charge and asked, “well now it seems that you are a baby now I have so many things planned, we can draw, make pastries, I’ll read you a bedtime story and then I can tuck you into your bed with your cute dolly.”

He looked up with a look of surprise and astonishment not really understanding everything Fluttershy said and just babbled, “yeah I a baby, I wana do all tat stuff ya said.”

Fluttershy giggled at Big Mac’s cute answer and asked, “oh really how old are you then?”

Big Mac shoved a hoof into his mouth and pondered the question a little before he exclaimed, “I three.”

Fluttershy dawwed, “oh your three! Well, I have to say your the biggest three-year-old I’ve ever seen.”

He squealed kicking about in his thick diaper making it shift about with his adorable waddle and ripple with every step as he proclaimed proudly. “Awesome! I ta biggest toddler ever!”

Fluttershy gave the stallion’s mane a pat and cooed sweetly, “yes you are now how about we make an apple pie?”

Big Mac started to jump up and down making the house shake as he screamed, “yeah can we make an apple pie!” Fluttershy hugged Big Mac's faced once more and ruffled his mane. “Oh, what a cutie.” She started to get out the supplies humming a tune as Big Macintosh started to grab the apples and began mashing them with his hooves shouting, “mash! Mash! Mash the apples!”

Fluttershy turned around in horror seeing the mashed glops of apple now spread out over the kitchen. “no Baby Mac that’s a no! no!”

The big red stallion turned around with a look of innocence on his face. “what are ya talking about? I mash ta apples as ya said.”

Fluttershy shook her head and in a condescending tone she explained, “No sweetheart we need to mash the apples like this gently.”

She took one of the un-smashed apples and began to mash it with a masher slowly. Big Mac watched with foolish intent the stallion’s eyes full of wonder gave the nod. “otay Fluttershy I wana try.” He tries his hoof on it as well and giggled and babbled with glee as he pressed his hooves into the soft apples. Fluttershy giggled and began to add other ingredients together into the filling. Big Mac continued to watch and help Fluttershy for some time both in making the pie filling and the pie crust. But as soon as Fluttershy was pushing the pie into the oven. Big Mac took the mixing bowl and started to shove the mixture into his mouth splattering it all over the kitchen. Fluttershy didn’t notice the mess that was forming until she looked around and saw Big mac eating out of the bowl and exclaimed, “big mac that’s a no! no!”

But the stallion continued to make a mess with glee splattering pie batter all over shouting “Pie! Pie!”

Fluttershy stormed over and swiped the bowl from his hooves as she scolded him. “That’s a big no, no Baby Mac you apologize.”

Big Mac started to whimper and began to wail as he bounded off making the whole house shake. Fluttershy chased him into the living room and gasped as Big Mac grunted and pushed a massive mess into his diaper making it bulge with a brownish color. Fluttershy groaned in disgust and stepped back as she whimpered, “oh dear, babysitting Big Mac is going to be a lot harder than I thought.”

Chapter 6: Babysitting Baby Big Mac ends?

Fluttershy was a mess with her mane frazzled and sprayed outwards, and her yellow coat was covered in a creamy batter and foal powder all over. The mare looked completely exhausted as she did everything she could to keep Big Mac clam down. The big red stallion was relentless in his tantrums making a mess out of the main living room and the kitchen. But the yellow pegasus somehow finally got the big red stallion into his bed, and he was taking a nap. Big Mac was deep under his covers with his diaper bulge clearly showing through the blankets. The big foal was snoozing away sucking his hoof sleeping soundly in his bed looking completely adorable. Fluttershy looked downward with a look of uncertainty as she watched the giant foal napping with a look of relief as she whispered, “I can’t believe I’m saying this, but I’m glad he’s finally asleep.”

Applejack came back from apple bucking, and as she rubbed the sweat from her brow she gasped at the disaster that was the kitchen, and the living room, toys diapers, batter were sprayed all over as if a tornado swooped in and just tore the place up. Applejack slowly walked upstairs cringing at every creak of the old rickety steps. She eventually made it up to the top and saw Fluttershy with her big sleeping brother and asked, “what happened down here?”

Fluttershy squeaked with fear at the sudden question and quickly looked around at Applejack and quickly lead her out of the room. She slowly closed the door so she wouldn’t wake Big Macintosh until the door was closed with a satisfying click. After that, they both went downstairs with Applejack a little concerned but acknowledging the fact Fluttershy didn’t want to risk waking her brother she followed suit. Fluttershy turned bowed down before Applejack and pleaded, “ I’m so sorry! He was such a troublemaker! I tried to get him to make an apple pie but he was persistent in eating it, and then he put up a temper tantrum then...then...he made a big poop in his diaper.”

Applejack’s face went green and gulped, “I...I’m so sorry Fluttershy…”

The yellow pegasus gave a massive sigh of relief as she continued to explain, “hey I cared for sick bears before, trust me it’s not the first time I cleaned after something so big.”

Applejack gave a chuckle,“ yeah well still, thanks again ya shouldn't have needed to do all that. Ya really went above and beyond.”

Fluttershy waved a hoof with a shy smile. “Oh don’t you fret things weren’t that bad….well besides the crying and temper tantrums. My goodness, he can be quite the big toddler.”

Applejack burst into laughter, and as she composed herself, the farm mare commented, “yeah not much different from when he was an adult. Anyways I’m done with the applebucking ya can go on home.”

Fluttershy shook her head and stated firmly. “Not a chance, I’m not leaving you here to clean up this mess.”

Applejack just shrugged and sighed, “alright, well ya can start in the living room I'll take care of the kitchen.” As Fluttershy went to the living room to start cleaning. Applejack sighed as she rubbed her head and whispered, “well I hope things can start getting back to normal soon, I don’t know how much longer Fluttershy and I can take this.”

As the two mares continued to clean downstairs for a few hours. Big Mac finally got up from his nap he could hear the two ponies talking,

“Yeah Big Mac pees so much, I swear he must have flooded his entire diaper twice while I was babysitting him and those things are huge! They're like mattresses!”

He then heard Applejack reply back, “yeah, I know ya should see him after an apple cider drinking contest. Heck I bet he could fill an entire lake with urine.”

Big Mac pouted being a little frustrated on how Applejack and Fluttershy were talking about him behind his back. The big foal got u and sat on the side of his bed looking down at his diaper now yellow and sagging between his legs. He whimpered and whined, “it’s not fair I wet the bed!”

Then seemingly out of nowhere he heard the voice, it’s alright of course it’s not your fault. It’s natural for foals like you to wet the bed.

Big Mac peered down at his doll and replied back, “yeah I know, but my big sissy and Auntie Fluttershy are being mean.”

the voice talking as if from Smarty Pants explained calmly, they’re mad at you, you need to leave and prove to those two meanies your just a little foal.

Big Mac whimpered hugging smarty pants close to his chest. “But where will I go? How will I prove to them?”

The voice whispered, “I know of a place where it’ll make you into a baby forever. But you're going to have to leave.”

Big Macintosh looked at his doll with a questionable look and asked, “won’t I get in big trouble though?”

The voice continued in a sweet but encouraging tone, “no of course not and you don’t need to worry. As a foal, you won’t get into that much trouble.”

Big Mac instantly jumped out of his bed with his saggy diaper swishing back and forth between his legs as he looked up with a determined look. “Yeah! I wana be a baby again!”

He quickly scurried over to his window and looked down at the ground below. The big stallion gulped with fear and whimpered, “but the ground is far, I gonna get a big booboo if I jump.”

The doll explained, “why don’t you use the rest of your super big diapers to help you?”

Big Mac looked over at the packages of diapers and waddled over to them. Big Mac began to rip the packages with his teeth making the packages of padding explode all over his room. With childish glee he began to tape the diapers all over his body like some patchwork of padded armor taped over each other. After what seemed like an hour, the giant red stalions was now encased in a white padded body with the little apples printed on them. The diapers crinkled and crackled with every little movement making Big Mac quivering with excitement. The big stallion bounced up and down making the mass of padding ripple as he lifted the doll and asked in excitement, “i’m ready Smarty Pants what do I do next!?”

The voice whispered, it’s time for you to go, now go to the window.

Big Mac slowly waddled over to his window and looked down at the street below. then looked down at the ground and whispered, “one...two..um...one hundred! He jumped out of the window and landed on the dirt road below using his diaper as a cushion to soften the fall. The big red stallion kicked about in glee before running off towards the Everfree Forest.

Fluttershy and Applejack were both in the middle of their conversation about Baby Big Mac. Then out of nowhere they heard a loud crash come from outside and mares looked at each other for a few minutes with wide eyes and blank expressions, then they both exclaimed at once. “Big Mac’s in trouble!”

They both burst through the front door and ran outside to see a trail of diapers leading off towards Ponyville in the night.

Applejack rolled a hoof down her face as she groaned with agony, “Ugh! There he goes again! Darn, that Big Mac he can’t stand still for five minutes!”

Fluttershy looked down at the trail of giant white diapers lining the road with the moonlight reflecting off the tapes. The mare couldn’t help but admire the scene with astonishment as she asked out loud, “why is there so many diapers?”

Applejack scoffed, “he probably used them to protect his fall, but he wouldn’t have thought of that himself, This must be something that has to do with the spirit.”

Fluttershy turned around towards her friend and exclaimed, “oh dear, we need to go after him before the poor little one hurts himself! Come on!”

She fluttered down the road as Applejack grudgingly followed behind growling, “That Big Mac is gonna owe me big for this!”

The two mares both ran along following the trail of giant diapers until they reached the edge of the everfree forest. Fluttershy gulped and whispered, “what could he possibly have to go into the Everfree forest.”

Applejack gave an irritated groan as she pulled her hat as she exclaimed, “I have no idea! but I’m starting to get a feeling we're gonna see the end of this spirit tonight once and for all now come on!”

They continued through the thicket of dead trees spooky trees following the stray diaper caught on the branches of trees here and there. It seemed like forever until they came upon a strange pool of water it was glowing with energy where big mac was with nothing left but his saggy diaper stripping it off with his teeth preparing to take a dip in the pool. Both Applejack and Fluttershy ran over as Applejack shouted, “ya stop right there young colt! You're in big trouble!”

Big Mac gave the mares a surprised look and stepped back now feeling scared and worried. Fluttershy calmly and gently fluttered over to him and cooed, “hey there it’s alright we’re just worried about you is all. What are you doing here?”

Big Macintosh hid his face behind his hooves and mumbled, “I just wana be a baby again.”

Applejack now beyond irritated at this point and stomped a hoof onto the ground as she shouted. ‘Stop this nonsense your a bucking grown stallion!”

Fluttershy gently cooed, “oh we know dear, we're just concerned that other big ponies will make fun of you if they see you in your diapers.”

Big Mac turned to Fluttershy ignoring his sister's protests as he jumped and down making his diaper squelch and squish as he chirped with excitement. “That’s why I’m here! I’m going to be turned into a foal! And I’m gonna be a baby pony forever!”

This made Applejack gaped with her mouth open unsure of what to say. But Fluttershy simply asked in a concerned motherly tone, “who told you this sweetie? Was it a spirit?”

He shook his head and held up smarty pants and exclaimed, “not it’s Smarty Pants! She told me about this pool. She said if I go in it I can be an actual foal!”

Applejack had enough as she stomped towards her brother snatched the doll as she slammed it onto the ground with a hoof and proclaimed in anger, “you listen to me ya dang spirit your messing with my brother and me for long enough! Now here's my deal if ya don’t leave my dang family alone I’m gonna smash this doll into powder!”

But the spirit possessing smarty pants cried out, “help me Baby Mac! You need to go into the pool to save me!”

Big Mac turned towards the water and was going to jump in. However, Fluttershy held him by the hoof and tried to take him back. But the big stallion was too strong as he was starting to put a hoof into the water Applejack exclaimed, “wait don’t! I’m sorry for being mean to ya. There's no need to go into the water, just listen to your big sis for a sec.”

Big mac turned around with an angry look and asked rudely, “yeah like what?”

Applejack continued to walk over as she continued to explain, “look, Big Mac, I love ya a lot and heck I would love to see ya as a cute chubby foal. But honestly, we need ya for the applebucking season I can’t do this by myself! Without ya, we could lose the farm!? Please, ya need to stay as an adult!”

He gave his sister puppy dog eyes and stomped about as he whined, ”but..but ya dun like me playing with smarty pants or wearing diapers!”

Fluttershy brushed the big stallion’s mane as she cooed, ”we like you no matter what, come back to being an adult please.”

Applejack while not satisfied with her brother acting like a foal just sighed as she yielded and grudgingly grumbled, ”yeah as long as it’s not in public.”

With that big mac smiled as turned to his doll “Well, I guess that means I’m staying as a big pony!”

The spirit cursed and screeched, “how can you do this to me Baby Mac! You were supposed to be mine!”

Applejack scoffed, “as she looked the doll over the pool. “Your crazy if ya think ya can control my big brother. Now You're going back to where ya belong!” she tossed the doll into the pool as it hollowered and cursed, “you will all pay! I swear you will all pay!” The ponies watched as the poll bubbled and fog covered the area until the pool evaporated into nothing leaving just smarty pants in the muddy hole. Fluttershy was quivering scared to death from the curses the spirit shouted. Applejack slid down into the mud hole and took out the doll as she sighed, “ya caused a lot of trouble Smarty Pants.”

But luckily the doll didn’t respond and it seemed that the spirit has vanished. As Applejack climbed back onto dry land Big Mac’s derpy face slowly changed to that of one in utter confusion as he stumbled onto the grass with a loud embarrassing squelch. He looked down at the yellowed sodden diaper that sat between his legs with embarrassment. Then he looked up at the two mares asked with a nervous quiver in his voice he asked, ”what the buck happened!?”

Applejack came over with a deadpan look as she gave an exasperated sigh and simply stated, “it’s a long story.”

chapter 7: Applefoals

Twilight, Applejack, and Big Macintosh and were standing around the giant mud hole in the middle of the Everfree Forest. The big stallion looked down at the mud hole with his diaper changed of course with no padding around his rump. He was looking around the hole trying to figure out why he was here with complete awe. The stallion was unsure of what happened to him since he had his “nap” yesterday afternoon. Applejack came by and asked, “Hey ya feeling okay? Ever since the spirit left ya seemed more quiet than usual.”

The big red stallion was unsure as his mind was still full of confusion on what just happened. The big stallion was only able to respond with a small nod and mumbled, “Ey’yup.”

Twilight then rolled back her mane completely baffled and feeling a bit giddy over the situation and asked, “I’m sorry to ask this again, but do you really have no memories about what happened?”

Big Mac took a hoof and rubbed his chin trying to remember what happened to him. The last thing he remembered was Applejack finding him in his diaper and doll and feeling embarrassed about it. But after that everything was a blank shook his head as he explained, “no I...I’m completely confused I remember getting my diaper on and taking a nap. But that’s it, I have no idea what happened after that.”

Twilight slowly nodded her head as she raised a hoof and proclaimed, ”right it was the same with Spike and Applejack, this spirit is tied with the Everfree Forest and it’s dark magic. But the question is why and how would my grandmother know about this spirit?"

Applejack looked over with a concerned look in her eye and asked, “so if you don’t know about the spirit and what it was doing. Then how can we make sure that it won’t come back.”

Twilight blushed as she shrugged and replied, “I’m not sure, this is something I’m still trying to figure out.”

Big Mac looked over to Twilight and asked, “what about the doll? Did you want it to need it to spell had anything do with what happened?”

The purple unicorn shook her head and responded. “No of course not there’s no way my spell had anything to do with the spirit. It must've just transferred itself.”

Big Mac squeaked in horror stepping back and cried, “so the spirit can come back? I mean it’s not destroyed.”

Twilight scanned the area with her horn shining a bright light over the place trying to see if there’s any trace of dark magic and whispered, “well as far I can see there’s no trace of the spirit's magic and this pool...Its residue reminds me of something from Nightmare Moon.”

Applejack rubbed her head and asked, “so what you’re saying is that the spirit is something like what possessed Luna to become like Nightmare Moon?”

Twilight turned around and gave a nod, “yeah it’s something like that. I would need to talk to Luna and Celestia about this they would know more about evil spirits than me.”

Applejack’s eyes furrowed as she shouted, “What is ya talking about? I thought ya knew what was going on?”

Twilight with a sheepish smile explained “well kind of, my grandmother’s letter seems to have given me the wrong idea about the situation.”

Big Mac shook his head and whispered in a worried tone. “But still everypony in Ponyville saw me in diapers? I mean that thing ruined my life! We have to make sure this spirit is destroyed before it does something like this to some other pony.”

Twilight gave a nod as she turned towards Big Mac with an apologetic look and explained, “your right and I’m sorry for everything even if the “Want it, Need it” spell didn’t cause the power to make you act like a foal. This would've never happened if I didn’t overreacted on my late friendship lesson. So I’m sorry.”

Big Mac stepped back stunned unsure of what to say but Applejack came over to her friend and placed a hoof on Twilight’s shoulder. “Look, it’s not your fault, Big Mac and I both...well...used those uh cursed items and we kind of brought this craziness on ourselves. All you’ve done was try to help us out. I don’t blame you for anything.”

Big Mac gave a sigh and a nod with a simple, “ey’yup.”

Twilight looked up at the big red stallion with a reassuring smile and gave a meek reply. “Thanks, but it could take some time for me to track this thing down.”

Big Mac turned around with an angry look seeing that he was still embarrassed at the fact of everypony in Ponyville saw him waddling around town in a diaper. The big rrd stallion gave a long sigh. “Yeah but until then I’m going to hide my face from Ponyville for the next couple of months.”

Twilight blushed as she explained, “well most ponies forgot about Spike being in diapers. I’m betting that it’ll blow over eventually.”

Big Mac rubbed his face with his hoof and grumbled, “I hope so.”

Over a week past since the spirit of youth took Bug Mac. Now, Big Macintosh and Applejack trying to catch up on the apple bucking. The big red stallion was busy unloading the last of the bucked apples into the barrels for storage wiping the sweat from his brow. He then turned to see Applejack coming through the barn with sweat pouring from her brow completely exhausted as she slammed her back on the barrel. Big Mac smirked at his little sister and scoffed, “My goodness, that took forever huh? Do you want to go out to celebrate?”

As Applejack slowly got up as she wheezed, “yeah, food sounds good.”

They both finished sealing the barrels then they both began to walk towards Sugar Cube Corner. As the two trotted through the streets many ponies began laughing or snickering behind their hooves. Big Mac rolled his eyes as he did his best to ignore them but eventually as they entered Sugarcube Corner. A pregnant Mrs.Cake with a cheery smile standing behind the counter waved a hoof and chirped, ”oh hello dearies, does Big Mac need a bottle or..”

Everypony looked their way snickering. Big Mac's ears flattened against his face as he began to whimper as Applejack came up and growled, “he’s fine we just need two seats.”

Mrs. Cake blushed and waved a hoof. “Right I apologize.” she leads the two away to a booth where bog mac sat grudgingly as he growled, “seriously how long until ponies forget?”

Applejack shook her head and sighed “trust me I was treated like a five-year-old for some time from my incident. It’ll take some time getting used to.”

Big Mac was going to respond but the yellow coated Mr cake strolled over and asked, “Hey Applejack, Big Mac how are you two?”

Both ponies turned and looked over. Big Mac sighed in an irritated tone, “yeah I'm fine.”

Applejack grumbled, “yeah, we're doing well.”

Mr. Cake saw that the two ponies were a bit agitated. He quickly took some more notes.” so what would you two like to order?”

Big Mac turned around with an irritated look and grumbled “just some coffee and a half dozen donuts.”

Applejack looked up with a smile. “I would like a coffee along with a dozen apple fritters.”

Mr. Cake gave nod as he finished writing down their orders and chirped, “Alright you two! Your orders will be right up!”

He bounced off as Applejack looked over at her brother and whispered, “ hey it’s alright, you don’t need to be embarrassed.”

Big Mac rolled his eyes scoffed, “its easy for you to say. You weren’t parading yourself in a diaper in the streets.”

Applejack gulped and in a nervous tone, she confessed a secret, ”well...I did wear a diaper before Rarity helped snap the spirit out of me?”

Big Mac snapped back. “But no pony saw you! you have no idea how I feel!

Applejack eyes furrowed as she snapped back.”I was just trying to make you feel better knucklehead.”

He turned with a look of shamed and sighed, “I’m sorry I didn’t mean to be rude.”

Applejack shook her head. “Nah it’s fine you’re still mad about the whole thing. Ya, remember how I was after my incident with the dress? Trust me I know how your feeling is all.”

Before Big Mac could say anything Mr. Cake bounded over with a platter of food and with a nervous smile placed it in front of them as he proclaimed, ”Here we are, I hope you guys like it.”

Big Mac looked over with a smile and chirped, “Eyyup.”

Mrs. Cake waddled over as well as she cooed, ”oh just look at you two big ponies. You two grew up so fast.”

Applejack and Big Mac both whimpered hearing ponies snickered all over the bakery. Applejack instantly tried to change the subject looking at the pronounced belly and asked, ”how long until your due?”

Mrs. Cake blushed rubbed her belly. “Only five months to go. I didn't expect to get so big already. we might have more than one.”

Applejack smirked, ”aww cute, well I hope one is a filly we need some strong mares around here.”

Mrs. Cake waved a hoof. “oh I'm with you there I would love to have two fillies.”

Mr.Cake squeaked in horror as he was still unprepared for fatherhood. “Oh come on, we don't know if you have twins yet!”

Mrs.cake smirked as she proclaimed, “oh vome on sweetie think it's obvious, but come on let's have our guests eat in peace.”

As the two ponies left Big Mac turned and began to eat his donuts and Applejack ate her apple fritters. Big Mac sighed “so...Yeah...I guess you're right…ponies will eventually forget..."

Applejack smirked and asked in a condescending tone. “you sure you don't need me to cut that up for you first. I dont want you choking.”

Big Mac scoffed and snapped back,“you sure you should be out without a frilly dress.”

Applejack growled as she threw a fritter at Big Mac's face smearing the pastires all over his muzzle. He growled and threw a donut back and soon the two got into a food fight throwing pastries at each other. Soon the two were laughing and having a blast unaware of the chaos they were creating.

Chapter 1: First the doll now this!

Applejack and Big Mac were busy bucking apples together a week after Twilight’s mishap of putting a “want it need it” spell on some old rag doll causing half the town to go nuts. But as Applejack was busy bucking apples into baskets, she was concerned about her brother. The other night she saw him with that same doll sleeping soundly with it like a young foal. She looked over to see her brother busy knocking apples into his basket unaware of what she knew. The mare hasn't’ said anything yet because she didn't want to upset him. But it was about time she brought it up seeing that the spirit that possessed her and Spike was still on the loose. Applejack cleared her throat and casually asked, “So Big Mac I don’t want to alarm ya but ...I saw the plushie ya sleeping with the other night. Do ya mind telling me what’s that about?”

He squealed in freight, and his face became a deep pink from embarrassment with sweat now running down his forehead. Applejack continued in a reassuring tone, “now I don’t mind ya sleeping with a doll, and all but ya should tell me if something is going on.”

He shook his head and answered with a simple. “Ey’nope.” He drifted away from Applejack and continued applebucking away from his sister. All the while bucking harder he thought to himself how Applejack shouldn't put her nose where it doesn’t belong. Then a voice entered his mind, that’s right...you don't need her permission to do anything.He nodded thinking yeah your right at least she doesn't know about the other thing.

He blushed hard thinking about his past time of wearing diapers and acting like a foal. The voice whispered. Yes, you love being a little foal and I think it’s about time you started wearing your diapers more.

Big Macintosh shivered with anticipation of wrapping his rump in a thick diaper and began to buck apples again with a faster pace wanting to get this over with. As Big Macintosh bucked away Applejack more concerned, then she before came over and stomped a hoof as she explained. “I’m being serious! As much as I accept ya in every way, it’s still uh not normal for an adult to be sleeping with a doll. Ya, not hearing voices or anything are ya?”

Big Mac shook his head and grumbled irritably, “Ey’nope.” He then went back to bucking trees with some more aggression being irritated that his sister wasn’t dropping the subject. Applejack gave a loud sigh as she stopped and went back to bucking she thought to herself that the next time she sees her brother with that doll, she’ll observe what happens to see if anything was anything out of the ordinary.

After finishing with the work by sundown, the two earth ponies began to pour the apples into the wagon and as Big Mac hitched himself to the wagon. Applejack couldn’t help but come over and gave a reassuring tone explained, “Look, Big Mac, I don’t care if ya like dolls. But if a voice is saying stuff in your head, it could be the curse that Twilight was talking about. Ya, swear that doll doesn’t have anything to do with that?”

Big Mac shakes his head one more time and stomped a hoof to the ground and replied with a simple. “Ey’nope.” He then trotted off with his head held high and went straight to the barn to store the apples. As he slowly dumped the apples into each barrel, he heard a voice in his head. Hello, Big Mac if you want you can relax in your diaper after we're done?

Big Mac pondered for a second, well granny smith is out on a date with Golden Delicious and Apple Bloom will be in school for a few more hours...but what about Applejack I don’t want her to see me in a diaper. The stallion shivered at the mere thought of his sister catching him in such a ridiculous foal garment.

The voice continued oh but we both know your sister. She’ll probably work until sundown. This is the perfect opportunity to have some fun.

The stallion blushed profoundly and stored the wagon with the rest of the farm equipment and ground a hoof in the dirt. “Your right this is a great opportunity, besides I can see if I can use that new foal bottle I bought.”

The voice continued, good idea now hurry up every second we waist here is one where you can be snug in your diaper.

Big Mac gave a slight nod and moved his way to the front of the barn. He stuck his head out and looked around the place. Far in the distance, he could see his sister still busy bucking apples. He smirked seeing an opportunity and rushed off to the house with breakneck speed. The big stallion quickly bounded up the stairs shaking the house with every step and burst into his room slamming the door and locking it behind him. As the big stallion caught his breath, he looked over on his bed and found the odd stuffed rag doll sitting on top waiting for him. He quickly picked it up and snuggled it to his chest as he cooed, “oh I missed you so much Smarty Pants!” The stallion gave his doll a kiss on the cheek then he settled it down and ducked his head under the bed and he dragged out a small wooden chest on top in black marker was written on the front of it. “Big Mac’s stuff.” Big Mac looked down at the chest with a nostalgic smile seeing this was his old toy chest from when he was a colt. Then he pulled out a dark blue package of “adult diapers” these were custom made and were very expensive costing him nearly half of his savings for only a couple packages, but the money was well spent.

The anxious stallion pressed a hoof into the package making it crinkle loudly. He bristled with tension an gently peeled the plastic packaging with his teeth and a plethora of tightly package diapers exploded from within making the stallion squeak in surprise. He dropped the packaging and watched as the diapers burst out. He blushed to see the big white plush squares fly down all over the place and were now strewn about. Big Mac couldn’t help but chuckle, “it looks like it rained diapers in here.” He quickly began to pick them up and placed the diapers into his chest. After cleaning up the mess, he took the last big diaper and placed it on the bed so he could admire it. The padding had his cutie mark a big green apple printed on the back of the diaper where it will form around his rump. He then turned the packaging over to see where the light green landing zone for the plastic tabs will sit. Big Macintosh couldn’t hold it back any longer he took the thick plastic plush square from within and hugged it to his chest smelling the familiar clean diaper scent. Satisfied with his diaper, he put it aside and then dug into his chest and pulled out a big green plush changing pad with little red apples printed on the fabric. He slowly unfolded it and laid on the ground with care then he took out a big pink bottle of fresh foal powder and sprinkled a good amount of the powder onto the innards of the diaper.

Big Mac admired his little changing station and gave a nod of approval. “This is perfect now for the hard part.” Then the big Stallion began to take the giant diaper and unfolded it and placed it onto the mat and then slowly laid his big body onto the big green changing pad. Big Mac then slowly let his rump sink into the plush fabric and the soft foal powder. Big Mac gave a deep sigh of relief feeling the hours of painful labor seem to melt away with the diaper soaking up his aches and pains into its plush interior. Big Mac pulled up the front of the diaper over his belly with his hooves and secured the diaper with the big green tabs around his waist with his mouth. After making sure the tabs were snug the stallion kicked around in his fresh diaper making sure it fit. The diaper despite crinkling stayed on snuggly around Big Mac’s rump.

Big Mac squealed in delight taking his plushie and swinging it around. “Oh my Celestia! This feels so amazing!” He then jumped onto his bed and snuggled smarty pants close to his chest feeling the diaper encased his rump in its soft pillowy fabric.

The voice laughed in his head, oh my looks like some colt is having fun.

Big Mac blushed as he snuggled his doll. “Yeah, I am! But something is missing…”

The voice continued, your new foal bottle, do you want to try it out?

The stallion burst from the bed and exclaimed, “Yeah that sounds like a good idea!” He then hurried to his chest and dug through it until he found a big glass foal bottle. It was enormous with being half the size of his body with the amber nipple already in place. Big Mac got up blushing to realize he forgot the milk.

The voice cooed in his head. “Go on and get your milk. Nopony’s here.”

Big Mac gave a small nod and slowly got up with the weight of his diaper dropping down with a loud crunching noise. With his big green apple cutie mark now printed on his padded rump. He wiggled about as he took his first few steps making loud and adorable crinkling sounds. To most ponies, this would be embarrassing, but for Big Mac, he was happy and relieved at the sound making him feel comfortable and relaxed. The big adult foal waddled though his room then went downstairs with his big diaper shaking back and forth with each step. But when he reached the final stair, he peaked around making sure no pony was there. He then crept to the fridge with only the sound of his diaper crinkling making some noises and slowly took out a big jar of milk. Then once he had the jar of milk on his back, the padded stallion slowly moved up the stairs and headed to his room. There he shut the door and quickly poured the creamy substance into his foal bottle with patience. After draining the entire jug of milk into his enormous foal bottle, by the time the jug was empty the white cream only filled his bottle halfway. Big Mac chuckled slowly taking the bottle into his hooves as he laid on his back using not only his front hooves but his back ones held the bottle as well. When he was in position the big stallion began to suckle milk from his bottle like a helpless foal.

The voice whispered. That's right my good foal keep drinking and be happy.

Applejack however after an hour of bucking apples noticed her brother has yet to return. She grumbled, “that lazy Big Mac better not be doing what I think he's doing.”

She stomped off to the barn and burst through only to see that it was empty. But every barrel inside was filled to the brim of apples, and she scratched her head and whispered, “huh thought he would be in here taking a nap again.”

She then turned her head towards the house. "unless...unless he's playing with that doll again.”

Applejack left to the house and slowly opened the back door peeking inside to see it was mostly empty. Then as she slowly went in, she climbed upstairs to find that the place was still empty yet she heard an odd crinkling noise echoed throughout the home. The mare slowly trotted up the stairs trying to make as little noise as possible until she came to Big Mac’s door. She then heard another sound an odd noise like something was being sucked on. Without hesitation she burst into the room, and upon seeing Big Macintosh rolled up in a huge diaper with a foal bottle in his mouth. Her face turned red with anger as she shouted, “First the doll now this! What the buck Big Mac!”
