Almost done! Just one more chapter to go after this one! Hope you all enjoy!

After packing up their picnic and walking back to the cabin, the pair quickly snapped back into their roles as a Nana and her precious foal. Sugar Belle wasted little time in returning to her toys, the sounds of foalish giggling filling the cabin. Eventually though, Sugar Belle grew bored with this, which was when Nana decided now was good time for her foal to take a nap. Despite how fussy she was about having her playtime interrupted, all it took was one lullaby from Nana and she was out like a light.

While she napped, Wood Chipper returned from his trip into town, dropping off the crayons and paper Sugar Belle had asked him for. Thankfully, Big Mac had the foresight to undress himself before then, thankfully avoiding the potential embarrassment of needing to answer the door in a dress and makeup. When Big Mac had nudged Sugar Belle from her nap and told her about the colouring supplies waiting for her, she had been a bubbling well of excitement as she was carefully lead downstairs by Nana to play with her new toys.

Sugar Belle hummed to herself as she suckled her pacifier, happily scribbling away with her crayons. Having fully embraced her inner foal, Sugar Belle wasn’t even bothering to use her magic as she clutched the crayon tightly in her hoof as she drew. Across from her, Big Mac was occupying himself with a crossword puzzle book he had brought with him, occasionally peeking over at Sugar Belle to see how she was coming along with her drawing.

Younger than a Mare, five letters… Big Mac didn’t have to think hard on that one, writing “filly” into the boxes. Moving onto the next clue, Big Mac tapped his pencil lightly against his chin in thought. Valuable or beloved, eight letters…

“Look, Nana!” Sugar Belle suddenly exclaimed, derailing Big Mac’s train of thought for a moment. “Look what I drew!”

Setting his book down, he smiled as he saw what Sugar Belle had drawn. If you didn’t know any better, you would think an actual foal had drawn it with how messy it looked. Still, Big Mac could still make out what appeared to be a house in a green field, several trees in the background while the sun shined brightly in the sky. Standing next to the house were two pony shaped blobs, a red one and a pink one. Above the blobs, Sugar Belle had also scribbled in messy writing “Nana” and “Me!” to tell them apart.

“I drew us!” Sugar Belle giggled. “Isn’t it pretty?”

“Why, it looks wonderful, dear!” Big Mac cooed, walking over and patting the foalish mare on the head, succeeding in earning even more giggles from her. “I think somethin’ this wonderful deserves its own spot on the fridge. Would you like that if Nana hung your drawin’ up on the fridge?”

Sugar Belle nodded her head in response. Still smiling, Big Mac took the image and strolled over to the fridge and pinned the drawing to it with a free magnet. “There! Now everypony can see how talented my little filly is!”

“Yayyy!” Sugar Belle cheered, clapping her hooves together excitedly. “I’m gonna draw many drawings for Nana to hang up on the fridge!” Picking up her crayon, Sugar Belle went right back to doing just that, suckling her pacifier as she focused onto her drawing.

Big Mac felt his heart fill with warmth at the sight of Sugar Belle so focused on her drawing. She looked so happy, so carefree, so… A lightbulb lit up in Big Mac’s head as he walked over and picked up his crossword book again. Eight letter word for ‘valuable or beloved’… Sparing one more glance at Sugar Belle, Big Mac filled in the answer:

Precious.

****

As evening bled into night, Big Mac cooked up a nice dinner of apple salad, mashed potatoes and steamed carrots for the two of them, happily feeding Sugar Belle her meal at her request.

“Very good, Sweetie Pie!” Big Mac praised her as he fed her the last of her supper. “You managed to eat it all without making a mess. Nana is so proud of you!” Once Sugar Belle had swallowed the last of her food, Big Mac reached over and began to tickle Sugar Belle’s belly, a fresh bout of giggles erupting from the foalish mare’s mouth. “Who’s Nana’s little Sweetie-Pie? You are! Yes you are, yes you are!”

“Na—Nana!” Sugar Belle pleaded as she was tickled, second away from wetting herself from laughter. Luckily, Big Mac stopped his tickle torture before that could happen, allowing the mare to catch her breath.

“Since you’ve been such a good filly for Nana,” Big Mac said, “I think you’ve earned yourself a reward, my adorable Sweetie Pie.”

“Yay!” Sugar Belle’s tail wagged behind her as she watched Big Mac walk over to the fridge and remove a bottle of milk, licking her lips as he warmed it up for her. However, her happiness became confusing as Big Mac began to walk towards the living room. “Ummm… Nana?”

Glancing over his shoulder, Big Mac smiled as she said, “Come along now, Sweetie Pie! Nana has a special surprise for you in the living room!”

Still confused, Sugar Belle climbed down from her chair and waddled behind Big Mac into the living room. As Big Mac climbed up onto the couch, her patted the spot next to him. “Hop up, dear. Nana knows you can do it.”

Sugar Belle’s eyes widened as the pieces began to connect in her mind. Does… does this mean he’s going to… Despite a few awkward attempts thank to the thickness of her diaper, Sugar Belle finally managed to hop up onto the couch (with a little help from Nana, of course), scooching closer to Big Mac as he patted his lap.

“Lie down for Nana now, dear…”

Sugar Belle’s heart hammered away in her chest as she laid down in Big Mac’s lap, her pacifier removed as he held the bottle over her face. This… this is really happening… I’m about to fed a bottle like a… like a foal!

“Now, open wide for Nana!”

Opening her mouth, Sugar Belle didn’t have to wait long before she felt the nib of the bottle pass her lips, automatically sucking away as a stream of warm milk filled her mouth and flowed down into her belly. Sugar Belle was in utter heaven, her body tingling with warmth as she was fed her bottle like the foal she was. So comfortable was she in that moment that Sugar Belle didn’t even notice as she began to wet her diaper, too lost in the tranquil bliss of being Nana’s foal. Time lost all meaning as Big Mac began to sing to her, her eyes beginning to grow heavy. She probably would have fallen asleep right there if not for the bottle finally running dry, her belly now filled with warm milk.

“There we go! All done your baba!”

Sugar Belle barely registered Big Mac’s voice as she felt her body shift, too lost in euphoric bliss to notice as Big Mac picked her up and rested her chin on his shoulder. She felt his hoof caress her back for a moment before he gently tapped her on the back, once, twice… “URP!” Sugar Belle blushed as she let out a loud burp, a line of drool dripping from her mouth onto Big Mac’s shoulder.

“That’s it, let it all out for Nana. We wouldn’t want you to get a tummy ache, now would we?”

Giggling at the knowledge that she had just been burped for the first time since she was an actual foal, Sugar Belle nestled into Big Mac’s embrace as she reached up and wrapped her arms around lovingly around Big Mac’s neck. “”Thank you, Nana,” Sugar Belle said as she nuzzled against Big Mac’s shoulder. “This has been one of the happiest days of my life. I wish we could stay like this forever…”

“Me too, Sweetie Pie…” Big Mac murmured as he rubbed Sugar Bell’s back. “Me too…”

The couple sat there together for sometime, both wishing that they could stay this way forever. Sadly, it wasn’t meant to be, as the two knew in their hearts that they had responsibilities and friends and family back home, things they couldn’t ignore no matter how much they desperately wanted to. Still, the two ponies took a small solace in the fact that their time together had been spent well, greatly strengthening their relationship as they allowed the other to indulge in their wildest dreams.

Still, that didn’t mean they couldn’t still continue enjoying every last minute of their time together before they had to head home, a fact pointed out as Big Mac put his hoof on Sugar Belle’s diapered rump and gave it a squish. “My my, you really filled this one, didn’t you? I think somepony needs a change into a fresh diaper, doesn’t she?”

Sugar Belle giggled as she pulled away from Big Mac and hopped down from the couch, waddling happily as she was lead upstairs for a well needed diaper change.

****

And so, the final day of their stay finally arrived. After a morning spent playing together as Nana and her foal one last time, the couple reluctantly changed out of their roles and began to clean up the aftermath of their brief stay. Any remaining food was packed neatly into the cooler, all the clothes and items they had brought with them had been packed away into their respective bags, their beds were neatly made and any trash (especially all of Sugar Belle’s used diapers) had been collected and scooped into a large garbage bag before that was then tied up inside a second garbage bag.

Woods had informed them when they had arrived that any trash wouldn’t be thrown out until the day after they left, so the pair wanted to make absolutely not to leave any evidence of their special activities behind. After finishing up dusting and cleaning around the cabin, you wouldn’t even know that a pair of ponies had just spent the weekend there.

Woods arrived soon after to escort them to the station, as well as see them off. “Now, don’t be strangers, ya hear?” Woods said as the train pulled up to the station. “Feel free to come back anytime and visit if’n yer in the area!”

“We will,” Sugar Belle said as she walked up and gave Woods a quick hug. “Thanks so much for all your help.”

“No need ta thank me, dear. As I said, any friend of Rarity’s is a friend of mine! Oh, and please say hi to Rarity for me when ya get back to Ponyville, would ya?”

“We will, don’t worry.” As the train signalled for passengers to embark, Big Mac and Sugar Belle waved one last goodbye to the old Earth pony as they climbed onto the train and took their seats. In mere moments, Vanhoover station was behind them as the train set off for Ponyville.

As Sugar Belle watched the hillside zoom by them, she sighed as she pressed her hoof to the glass. “Looks like our little get-together had finally come to an end…”

“Eyup,” Big Mac replied from beside her.

“Still, it was certainly a memorable one, wasn’t it?”

“Eyup,” Big Mac said with a smile as he leaned over and nuzzled Sugar Belle’s cheek. “Who coulda ever imagined the weekend would’a ended up like it did?”

“I’ll say!” Sugar Belle said with a smile as she rested her head against Big Mac’s shoulder. “Still, it was fun while it lasted, wasn’t it?”

“Eyup…” Was Big Mac’s reply as he glanced out the window. “Ya know… it doesn’t have to end just yet. Ya could always stay for dinner, I’m sure nor Granny nor Applejack wouldn’t mind.”

“Hmmm…” Sugar Belle thought for a moment before sighing. “As much as I’d love to, I really should be getting home and back to my little bakery. Plus, Double Diamond and the others will probably want to hear all about my big weekend away with my special somepony.” Glancing up to see Big Mac frowning slightly, she giggled as she said, “Don’t worry, I intend to give them the short version if they ask. Our time spent as Nana and foal will stay just between us, as it should.”

“Eyup…” Big Mac said one last time as they two became silent, happy to just share one more moment together.

“Approaching Ponyville Station!” The conductor’s voice soon filled the cabin. “Any passengers getting off at Ponyville Station prepare to disembark! I repeat, any passengers getting off at Ponyville Station please prepare to disembark!”

“Well, there’s my stop,” Big Mac said as he began to pull away from Sugar Belle. Before he could though, Sugar Belle took the chance to land one last kiss on his cheek, causing the big stallion to practically melt in his seat. Leaning forward, she whispered something into Big Mac’s ear, something that caused a smile to spread across his face as he leaned over and whispered something back. As the train pulled into the station, Big Mac finally pulled away to collect his luggage before making his way for the nearest exit.

Applejack was there to greet him as he disembarked, running up her big brother and giving him a big Apple Family hug.”There ya are, ya big goof. So, how was yer weekend away with Sugar Belle?”

“It was…” Glancing over his shoulder, Big Mac smiled as Sugar Belle waved at him from the cabin, waving back at her as he said, ”… lovely.”

Applejack chuckled at the dopey, lovestruck look plastered across her brother’s face. “Well now, as glad as I am to her that, I hope ya haven’t gone soft on me after a few days away with yer marefriend! There’s still plenty of chores to be done back on the farm, and you’ve got a lot of time to make up for!”

“Eyup!” Big Mac replied, the two laughing together as the train began to pull away, Big Mac’s gaze following Sugar Belle the entire time as the train set off down the tracks towards its next destination. Picking up his bags, Big Mac slung them over his back at the two Apple siblings made their way down the path back into Ponyville.

“Reckon y’all were right, Applejack,” Big Mac said suddenly, catching Applejack off guard for a moment.

“Right about what?”

“When ya said I’d ‘appreciate this after gettin’ to spent some time with Sugar Belle’. A weekend away was just what I needed, and I’m glad to have a sister like you lookin’ out for me.”

“Darn tootin’! Somepony has to be there to wrangle your stubborn behind! Now come on, Granny’s got a fresh apple pie waiting’ for us back home!”

Smiling, Big Mac set off for home, thinking back to the words Sugar Belle had whispered into his ear before they’d parted:

Until next time… Nana.

[Sugar Belle]

As Ponyville Station disappeared from sight, Sugar Belle sighed as she leaned back in her seat. Despite needing to part with Big Mac for now, her heart was still filled with warmth at the knowledge that they would be together again soon, reaffirmed by the words Big Mac had whispered lovingly into her ear:

Until next time… my sweet foal.
