Big Mac and Sugar Belle have been together for almost six months, and both have been keeping a secret from the other, a secret that both fear could end their relationship in an instant if the other knew. When their secrets finally become known, however, the couple may find they have more in common than they first thought...

“Are you sure you can’t stay any longer?” Sugar Belle pleaded as she watched Big Mac hook himself up to the empty cart, glancing briefly over at the horizon. “It’ll surely be dark by the time you get back! You could always stay the night and—“

“Nope,” Big Mac quickly interjected, sighing as he fixed the unicorn mare with a sad look. “Believe me, I would love to want to be spendin’ more time with ya, Sweet-pie…”

Sugar Belle blushed as Big Mac called her by the pet name he knew she loved, sending her heart all a flutter.

“… But I still have chores to do on the farm. My family is countin’ on me to help them out, so I can’t stay any longer.” Walking up to his marefriend, Big Mac gently nuzzled her cheek as he whispered into her ear, “No matter how much I want to spend more time with ya.”

Giggling, Sugar Belle nuzzled Big Mac back, the smell of fresh apples filling her nose. “I know… Is it selfish of me to want to spend a few more moments with my special somepony?”

“Nope,” Big Mac replied, nuzzling Sugar Belle a few moments longer before reluctantly pulling back. “I’ll come visit y’all again in a few days, promise.”

“I’ll hold you to it!” Sugar Belle said jokingly, smiling as she watched her big, strong stallion turn around and begin the slow trek towards the edge of town. He had only gotten three steps away before she called out to him. “Wait!”

Pausing, Big Mac turned his head slightly to glance behind him, only to be taken aback when a set of soft lips pressed against his cheek, a dopey look appearing on his face as the stallion positively melted from the kiss.

“One for the road,” Sugar Belle said, giggling at the lovestruck look on Big Mac’s face. He is so easy to tease sometimes! She thought as she watched him canter away, a renewed bounce in his step as he set off for home. She stood there watching him until he disappeared over the hills, a profound sadness lofting over her when she could no longer see his red backside. “I miss him already…” Sugar Belle said longingly as she turned and walked back into her shop, closing the door behind her with a sigh.

Strolling into the kitchen, Sugar Belle began to occupy herself by preparing a fresh batch of cupcakes for the shop, hoping to take her mind off the feelings of loneliness that always followed after Big Mac’s visits. Ever since Big Mac had entered into her life, Sugar Belle felt happier than she could remember ever being. No matter what kind of day she was having, all it took was one look at her colt friend and all her worries would just wash away. Just picturing herself walking alongside him through town, their sides brushing up against each other as they walked, laughing together as they enjoyed a nice meal, before retiring to her bedroom so she could snuggle up tight with the stallion as they—

Sugar Belle gave a sharp shake of her head, her cheeks tinted red from the scintillating image now in her head. No, bad Sugar Belle! Now’s not the time for such fantasies! You’ll ruin the cupcakes! Doing her best to push the image from her mind for now, Sugar Belle worked on pouring the batter she had been mixing into the pans, smoothing them out before gently popping them into the oven to bake.

As she set the timer for the cupcakes, she couldn’t help but smile as an idea wormed its way into her head. Besides, there are still other ways I can enjoy myself…

[Big Mac]

Just like Sugar Belle had said, the sun was almost done slipping below the horizon as Big Mac finally crested the hill and saw Sweet Apple Acres just ahead. For most of the trip, Big Mac had been in a daze, still left in a lovestruck state from Sugar Belle’s parting kiss. But as he reached the gates to Sweet Apple Acres, he felt the toll of that day finally make itself known, the aches in his legs draining him of all the excitement and joy seeing Sugar Belle had filled him with. At the moment, Big Mac wanted nothing more than to just crawl into bed and rest until the rooster crowed the next day.

After stowing the cart in the barn and unhooking himself, Big Mac strolled up to the house and let himself in, his ears perking up at the sound of paws stampeding across the floor, bracing himself not a moment too soon as Winona came barreling around the corner and leapt up at him, licking his face excitedly.

“Alright, alright,” Big Mac chuckled as he gently pushed Winona back down, smiling as she wagged her tail at him. “I’m happy to see ya too, girl. Were you a good pup while I was gone?”

Winona gave a sharp yip in response, as if to say, “Yes! I was a very good girl!”, which earned her a loving pat on the head from Big Mac.

After a moment, Big Mac began to notice how strangely quiet the house seemed. “Say, girl… you wouldn’t happen to know where AJ and the others would be, do ya?”

Replying with another excited bark, Winona raced off into the kitchen, Big Mac following behind her moments later. When he entered, there was still no sign of his sisters or Granny, but he did notice Winona sitting in front of the fridge. As he got closer, he saw a note stuck to the fridge that hadn’t been there when he had left earlier that day, peering closer to read what it said.

Big Mac, got called away by the Map suddenly, so had to take off while you were gone. Apple Bloom and her friends are holding another one of their Day Camps to help others find their cutie marks, and what with Granny away at her bingo tourney…

“Oh, right…” Big Mac muttered, having completely forgotten that Granny’s Bingo Tournament was tonight.

… That leaves just y’all and Winona to hold down the fort for now. Don’t think this means you can shirk on your chores! You know full well that harvest season in just round the corner, so we need to get started if we’re gonna make it in time! Anyway, shouldn’t be gone long, be back to help as soon as I can.

-Applejack

Big Mac hmmed in thought as the contents of the note sunk in. Other than Winona, he had the house all to himself, something that rarely happened. Even with all the duties Applejack had been undertaking alongside her friends, and Apple Bloom and her friends getting their cutie marks, it was still pretty unheard of for the Apple Family home to be nearly empty. A smile split across his muzzle as the implications of this became known.

His aches and pains from before seemed to vanish in the face of the opportunity before him, because now was the chance for Big Mac to indulge himself in something he hadn’t been able to for some time, and he wasn’t about to waste a single moment of it!

A low growl from his stomach momentarily derailed his excitement, realizing that it had been some time since he had eaten lunch with Sugar Belle.

“Food first, indulgence later.”

[Sugar Belle]

With a smile on her face, Sugar Belle made her way upstairs after closing the shop for the night. As much as she enjoyed baking, she had been looking forward to this moment ever since Big Mac had left. While she still would have still loved it if he had decided to spend the night instead, the fact that he had refused was a blessing in disguise, as it gave her the perfect chance to indulge in a certain… “hobby” of hers.

Stepping into her room, she quietly locked the door behind her to make absolute sure she wouldn’t be interrupted. While it was unheard of for the ponies of Our Town to just waltz in uninvited, Sugar Belle wasn’t about to take any chances, especially considering the activity she had in mind. After pulling the blinds shut, Sugar Belle excitedly skipped over to her closest.

After rummaging around inside for several moments, she finally found what she had been looking for, pulling out a large rectangular package from inside. The bright pink packaging was covered in images of cartoon hearts, blocks, baby bottles and other such imagery associated with foals, except for the image of a full grown Pegasus mare on the front, smiling while wearing a visibly thick diaper on her behind. Written across the side in big colourful lettering were the words, “Forever Foals, Supreme Adult Foal Diapers.”

Smuggling such a large package into town without being noticed had been an endeavor Sugar Belle had spent weeks planning towards, but it had all been worth it in the end. Pulling out one the diapers from the already opened package, Sugar Belle pressed her nose into the plastic padding and took a quick whiff, sighing at the fresh scent of strawberry scented perfume laced into the padding. Giggling like a filly on Hearthswarming Eve, Sugar Belle pranced over to her bed, laying the diaper open on her covers before hopping up. The pink unicorn was a big ball of nerves and bubbling excitement as she lowered herself onto the soft padding, using her magic to carefully thread her tail through the hole in the back.

Just as she began to pull up the front, however, she gasped as she realized she had forgotten something. Leaning over her bed, Sugar Belle pulled several items out from underneath The first was a large pacifier, which she quickly popped into her mouth and began to suck happily. With that done, she floated over a big bottle of foal powder, which she used to sprinkle a flurry of white powder into her belly. Can’t be too careful!, she thought as she set the powder aside and once more worked on pulling them front of the her diaper up.

Her diaper… the mere thought of it filled her with glee as she finally pulled the diaper up and over her belly, quickly making sure it was aligned properly before taping it up nice and tight. Now securely diapered, Sugar Belle poked the front of her diaper, earning a rewarding crinkle in return. The diaper was a similar shade of pink to match her coat, and was decorated in adorable prints of teddy bears and blocks. Giggling, Sugar Belle began to bounce up and down, the creaking of her mattress drowned out by the loud crinkling of the diaper, the soft padding hugging her every curve like a fluffy pillow.

After several moments spent revelling in the softness and security of her fresh diaper, Sugar Belle hopped back onto the floor, the thickness of the diaper pushing her legs apart slightly and causing her to noticeably waddle, something that made Sugar Belle feel more and more childish by the second as she walked laps around her room, enjoying the feeling for the first time in so long.

For as long as she could remember, Sugar Belle had longed for the days of her foalhood, the days spent feeling carefree and happy. Unfortunately, she had given up those pursuits along with her cutie mark after she had joined Starlight’s town. After getting her cutie mark back, the feelings of wanting to be a foal had returned, and Sugar Belle had been unable to resist the temptation after so long. After that first night spent back in diapers, however, Sugar Belle knew she had made the right choice.

Eventually, Sugar Belle grew tired of just prancing around and decided it was about time she started getting into “character”. Still sucking her pacifier, Sugar Belle pulled out several foal toys from under her bed, including lettered blocks, a rattle and a child’s xylophone. As she waddled towards the toys, she made sure to levitate over her stuffed bumblebee (which she had named the original name of “Cupcake”) from atop her bed, hugging the plush animal in her arms as she plopped her padded rear onto the floor.

“Let’s pway!” Sugar Belle mumbled behind her pacifier, settling into a foalish mindset as she began to arrange the lettered blocks. “S-U-G-R B-E-L-L! Look, Cupcake! I spell my own name! Aren’t I smart?”

The stuffed bee said nothing as Sugar Belle devolved into giggles, playing with her toys without a care in the world…

[Big Mac]

After a quick dinner of leftovers, Big Mac quickly retreated to his room, making absolute sure to lock the door behind him and shut the blinds to his room. Even though he knew he was alone in the house and that Sweet Apple Acres was far enough away from Ponyville that he wouldn’t have to worry about prying eyes, Big Mac couldn’t help but break out into a cold sweat, his heart beating furiously in his chest at the real chance to get to indulge in a rather strange “hobby” of his.

Once he made absolutely sure he was safe, Big Mac breathed a sigh of relief, though his heart continued to hammer away in his chest not from fear, but pure excitement. Walking over to his closet, Big Mac very nearly yanked the doors off their hinges as he threw them open, rummaging around inside before pulling out a seemingly innocent looking cardboard box. Once it was opened, however, it revealed a wealth of items that seemed very out of place for the stallion to own. Such as a bright curly yellow wig, which Big Mac was quick to pop onto his short mane, giving him a more bouncy and vibrant mane. This was the same one he had worn during the Sisterhooves Social, when he had disguised himself as “Aunt Orchard Blossom” so he could enter into the contest with Apple Bloom.

After the fact, it had been easy for him to brush away the entire thing as a one time thing, dressing himself up like a mare in order to please his younger sister. What he had neglected to tell any pony at the time, however, was that that hadn’t been the first time he had dressed up as Orchard Blossom, let alone the last.

Walking over to his mirror, Big Mac took a second to make sure the wig was nice and neat, before smirking at his own reflection. “My, my, don’t you look marvellous my dear!” Big Mac said, adopting the Orchard Blossom voice he had used during the Social. “Oh, but you’re still much too plain! We’ll have to fix that now, won’t we?” Returning to the box, Big Mac removed a white and blue trimmed dress with prints of apples across it, which he carefully and delicately put on. With that done, he removed two lengths of pink ribbon from the box, trying one around his neck before tying the other around his barrel, nicely holding the dress in place. After that, he removed a set of dress shoes from the box, daintily slipping his hooves inside. After slipping on a flower pinned band on to his fore-hooves, he returned to face the mirror, swishing the hem of the dress with his tail.

“Oh my, darling! You look positively stunning in that dress! Oh, won’t all the mares be jealous when they see you in this, hmmm?”

Of course, Big Mac had no intention of ever letting another pony see him like this ever again. He didn’t secretly yearn to be a mare, that much he was sure of, but he couldn’t help getting jealous seeing all the mares around town getting to wear such beautiful gowns. The first time he had tried on one of Applejack’s dresses while she was away, he had felt like a whole different pony, modelling himself in the mirror for hours after that, filled with an almost unexplainable joy.

“Oh, but you’re not quite done yet, darling!” Big Mac said to his reflection. “There’s still one more thing until you’re really beautiful!” Nodding his head, Big Mac returned to the box and pulled out a makeup kit. He still blushed from the the memory of the day he had purchased it for Rarity, saying that it was a surprise gift for Applejack. Big Mac could tell the mare wasn’t buying his story in the slightest, but she had still sold him the kit without a word and hadn’t anything about it since. Whether she knew what he intended to do with it or not, Big Mac couldn’t tell, but he was at least relieved by the notion that if she did know, that she had elected to keep his secret so far.

Pushing all that aside, the stallion in mare’s clothing turned back to the mirror, setting the kit at his hooves as she delicately picked up the eye liner tool and began to curl his eyelashes with apparent practiced ease, feeling himself become more and more beautiful with each passing second.

[Sugar Belle]

Time had lost all meaning to Sugar Belle, too immersed in the innocence of a foal playing with her toys. At the moment she was tapping away at the small xylophone, a smile on her face as she randomly struck each note. She might not have been playing anything, but to her it still sounded like music to her ears as she played, happily sucking away at her pacifier.

“Eep!” Sugar Belle gasped as she felt a growing warmth down below, almost losing her pacifier from the surprise. Glancing down, her eyes widened as she watched the front of her diaper darken as she freely wet herself, so lost in the mindset of a foal that she had barely noticed the urge to go until it had already been too late. At this point Sugar Belle couldn’t have stopped the flow even if she had wanted to (which she didn’t), so she just sat back and let it happen. Seconds felt more like minutes as Sugar Belle watched the previously fresh padding become used, seemingly captivated by the sight. Eventually, the flow stopped, but by that point the diaper had become visibly used to anyone who could see it.

And yet, Sugar Belle was still smiling, seemingly pleased with her little accident. After all, wetting her diaper like that was something a foal like her was expected to do, and knowing that she had done it made her feel even more like a foal than ever before. Scooping up her rattle, Sugar Belle shook the toy as she poked at her wet diaper, feeling it squish beneath her hoof. Flopping onto her back, Sugar Belle basked in the feeling as she sucked away at her pacifier and played with her rattle, feeling all her concerns just wash away.

As she lay there, her mind began to wander, conjuring up the image of her playing in her very own nursery. She would crawl around the carpeted floor, her diapered behind wiggling in the air as she played with her toys, not a care in the world. Suddenly, she would notice something odd, poking at her padding to find that it was wet. She would giggle and smile, continuing to play despite the wet diaper for some time before it would begin to get cold and clammy. Only then would she finally cry out, the cries of a foal echoing through the room.

After a moment, the door would open, and her Daddy would come in, the big, strong stallion soothing her as he carried her to the changing table and changed her into a fresh diaper, making her giggle as he tickled her belly. Now clean, he would then carry her to the kitchen for lunch, and she would just sink into his soft, red fur—

Sugar Belle’s eyes snapped open, bolting upward as her fantasy came to an abrupt end. Her pacifier slipped from her mouth and bounced against the floor, but Sugar Belle didn’t notice, too overcome with shame at herself. She couldn’t deny that that had been Big Mac in her fantasy, caring for her like she had always dreamed of. And yet, the thought of Big Mac knowing about her little secret filled her with nothing but fear.

What would he say? Would he think it was cute? Would he be disgusted? Would he… break up with me for it? Just imagining it made her stomach twist into knots. And yet, Sugar Belle felt even worse knowing that she was keeping secrets from him. Maybe I should…

A quick shake of her head dispelled that notion before it could fully form. No, I can’t. Everypony has there own little secrets, it’s just… Now fully awake from her previous foalish state, Sugar Belle glanced down at her diaper, the warmth having faded to be replaced with a cold wetness. “I guess I should get changed…” Sugar Belle muttered, yawning as she realized just how as tired she was. Getting up, she walked over to the package of diapers and removed a fresh one. She always did sleep best while diapered, after all.

After a quick change into a fresh diaper, Sugar Belle returned her toys to their spot under her bed and crawled into bed, hugging Cupcake tightly as she snuggled under the covers. As she drifted off to sleep, still sucking on her pacifier, a single thought was at the forefront of her mind:

He can never know…

[Big Mac]

In almost no time at all, Big Mac had nearly finished transforming himself from a normal stallion into an utter heartthrob of a mare. After curling his eyelashes just right, he had added a light blue eyeshadow to go with it, and was just about done powdering his cheeks. That just left one last thing to take care of before his makeover was complete.

Returning to the box one last time, Big Mac scooped out a small bag containing several sticks of lip gloss in a variety of colours. “Now, which colour would suit me best, hmm? Green? Nah… Blue, maybe? No, not quite… aha!” Smiling, Big Mac removed a a bright shade of pink lip gloss, giggling with excitement as she skipped back to the mirror to apply it.

With a gentle hoof, he carefully applied a smooth coat of lip gloss to his lips, puckering his lips and making kissy faces at his reflection. “My, my, dear, don’t you look simply divine tonight!” Posturing himself in front of the mirror, Big Mac made faces at the mirror, imagining himself walking down the catwalk, lit up by the flash of cameras as the crowd cheered him on. He knew he had made the right choice in going with the pink lipstick, it was one of his favourites after all. As he modelled for the mirror, he couldn’t help but notice how the shade of his lips matched Sugar Belle’s coat—

Big Mac froze. As if finally waking up from a trance, Big Mac stared at himself in the mirror, no longer enamoured with his looks as the image of Sugar Belle remained firmly stuck in his mind. “… What am I doin’?” He asked himself after a moment, now disgusted at the pony staring back at him. Here he was, a grown stallion prancing around in mare’s clothes like some kind of darn fool! And what if Sugar Belle ever saw him like this?! What would she think?!

Tears began to drip down Big Mac’s face, his makeup running as he tried to wipe the tears away and only managing to ruin the makeup even more. Overcome with shame, Big Mac tore off the wig and tossed it back into the box, soon followed by the dress, shoes and all the bits of makeup he now only felt disgust towards. After shoving the box back into the deep recesses of his closet, Big Mac raced to the bathroom to wash away the makeup off his face, soon removing any and all evidence of his activities.

Now overcome with exhaustion, Big Mac dragged himself over to his bed and crawled under the covers, hoping that sleep would remove any lingering traces of his shame. But sleep would not come easily for Big Mac, as he tossed and turned restlessly, knowing in his heart that this wouldn’t be the last time he would end up all gussied up in front of the mirror like before. When sleep finally came to him that night, one thought remained at the forefront of his mind:

She can never know…
