Cake Party

It was times like this that Fluttershy really wished she had an instruction manual for playtime. Everypony around her seemed to grab whatever colorful, plasticky toy they could find and played with it with such carefree bliss. She watched as the handful of ponies involved themselves in acts of pretend and impromptu tea parties. No words were exchanged or thorough explanations on what kind of game they were playing, everyone just seemed to...play. And in the middle of all that fun, Mcintosh and her sat quietly on a playmat with the toys around them going untouched and unplayed with.

She was certainly not going to make the first move. She didn’t even know where to begin. Wooden blocks and animal plushies dotted the floor around them and all she could worry about was making the wrong move. What if she picked up the wrong toy? What if she grabbed somepony else’s toy and they yelled at her? What if she messed up? What if she started playing with a toy that wasn’t deemed ‘age appropriate’? Was she a toddler or more of a baby? Did any of that matter? Did nothing matter? Did everything matter?

After an awkward pause, Mcintosh finally reached for a train set that sat on top of the pile of toys. Made primarily of wood, the toy was a chain of simplified train cars that connected to each other by little magnets on their ends. The simple plastic wheels struggled to navigate the cloth top of the foam playmat as he rolled it back and forth in front of him.

Fluttershy scooched closer to the playing stallion, sensing an unspoken obligation she had to fulfill. She still had no idea what she was going to do or what toy she was going to play with, but seeing the stallion fumble with the bulky toys sparked the helpful pony in her. She had to do something so he wouldn’t feel so left out.

No words were spoken between the two blushing ponies. They barely even made eye contact with each other realizing that was just too embarrassing to do. Fluttershy realized it was just like playing with her little animal friends back home. Maybe she was just over thinking all this and all she had to do to enjoy herself was to do what came naturally.

Mcintosh certainly seemed to warm up to her as they played. Or at the very least, his shoulders seemed less tense. Like Fluttershy, the stallion still blushed and bashfully avoided eye contact, but it was clear that he enjoyed the little playtime, despite the awkwardness. It was all going along so well until he suddenly acquired a worried look on his face. For a moment the blush in his cheeks drained, leaving a pale mask of panic as his eyes darted around the room. Without another word he carefully stood up as if he was cradling a basket of eggs on his back.

Confused, Fluttershy watched as the diapered stallion waddle over to Cream Heart who was cleaning up after the ponies’ mealtime. They exchanged words for a minute before Cream Heart shook her head and pointed back at the playmat. Whatever she said caused the stallion to slump forward with his ears lying flat on his head. Mcintosh didn’t say another word as he waddled back to the playmat, defeated. If anything he said even less than before and now appeared more rigid. He tried his best to act casual, returning to play as best as he could while not moving from his spot on the mat as much. Every slight shift he made was coupled with a pained wince and a worried look around the room. He was growing anxious about something and Fluttershy blushed to think what that could be.

“I’m back, sweet rolls!” Mrs. Cake chirped as she appeared trotting over to the pair. She had an invigorated spring in her step, “Mrs. Heart said you had something to tell me, Little Macky?”

Big Mcintosh threw a glance over at Fluttershy before quietly shrinking back as he mumbled something.

“What’s that, Little Macky?” Mrs. Cake announced, leaning over the stallion with an overly enthusiastic pose, “I can hardly hear you.”

“I-I need to uhm...G-go...” he replied with a meek and bashful voice.

“Go where, little one?” Mrs. Cake replied, she wasn’t letting him off so easily.

“T-to the bathroom...” he said, before correcting his vocabulary, “p-potty...”

“Oh I see, what a big boy asking to go potty!” the motherly mare cooed with a pat of the stallion’s head, “I have to check up on everypony else before I can take you there. Can you hold it for a little while?”

“Y-yeah...” Mcintosh gulped.

Carefully and continuing to wince every now and then, Big Mcintosh pulled himself up to his feet and followed Mrs. Cake as she trotted off to tend to the other ponies. He followed her around like a timid puppy, nearly nipping at the mare’s ankles as his back thighs squeezed tightly together. His large diapered bottom wagged behind him as his face curled up in discomfort. Things were starting to get dire and he silently wished for Mrs. Cake to hurry up.

And Mrs. Cake certainly didn’t make it easy for him. She made her rounds slowly and deliberately, frequently stopping to make small talk with the other ponies as the tall stallion whimpered and squirmed behind him. On the surface it appeared that she was just being a good host, but the smirking glance she would throw behind her at the stallion hinted at a more mischievous angle. Still Mcintosh tried to hold on as much as he could.

Fluttershy meanwhile tried her best to play alone, but now found her attention trailing elsewhere. Her gaze gravitated away from the pile of toys in front of her and toward Mcintosh who grew more and more tense as the minutes went on. She watched as his body language turned from rushed fidgeting, to slow and painful steps, nearing dangerously close to the edge of losing control.

Finally the pain was just too great, and Mcintosh stopped dead in his tracks as Mrs. Cake was just finishing up a delightful conversation with Pinkie Pie about their favorite colors of spring. He groaned lowly as his cropped tail began to rise. His back legs splayed out in a crouch as his head lowered to the cold tiled floor. For those observant few who were quick to notice, Mcintosh’s diapered rump could be seen rising into the air as his body tightened with involuntary muscle cramps.

Fluttershy watched the whole thing, wide eyed and breath shallowed. From her spot on the floor, she saw Mcintosh’s diaper slowly expand in the back and become heavier with each tightened squeeze of the stallion’s straining stomach. A hefty weight pulled his diaper down with an unmistakable lump sagging low between his legs. She watched as he buried his face behind his front legs in a weak attempt to muffle his involuntary grunts.

The tall stallion was stuck where he stood, frozen in the compromising position for all to see. When he did finally finished up after what felt like hours, he slowly pulled himself up, his face burning with shame. He stood up to see Mrs. Cake staring back at him with a disappointed tap of her hoof.

"And here Cream Heart was telling me how much of a big boy you were acting during snack time." She spoke loudly and dramatically, making sure to project her voice like an actress on a stage, “well judging by that BIG, MESSY diaper, I see she was wrong.”

There were a few giggles heard around the room, some affectionate ‘aww’s, and some ponies didn’t even look up because of how common a grown stallion in a messy diaper was at parties like these. Whatever their reaction, Mcintosh held his head low, far too embarrassed to even look Mrs. Cake in the eye. He had half a mind to speak up in protest and boast that he was a big boy, but those words only came out as pathetic little whimpers.

By the grip of his mane, Mrs. Cake tugged the stinky stallion away from the scene and headed straight for the changing room. However just before heading over there, she made a quick stop over at Fluttershy’s play area where the quiet pegasus continued to stare at the stallion’s hefty diaper.

“Fluttershy, would you mind being my little helper while I change Little Macky?” she asked.

Startled at first, no words could form themselves in Fluttershy’s mouth. She could only give the motherly mare a meek nod as she slowly stood up. Mcintosh continued staring at the ground, too humiliated to look up. It was tough to tell who blushed the hardest.

Once again, Fluttershy found herself back in the changing room. The ever present smell of baby powder now competed with the stench of old diapers as the festivities outside continued throughout the day. She watched with bated breath as Mcintosh rolled onto his back, taking great pains to avoid lying directly on top of his lumpy diaper. Her chest continued to flutter as she savored the seconds of watching the adorable diapered stallion fuss over such a tiny thing. She paid especially close attention to the sizable lump that formed around his backside, a sight she didn’t notice she was staring at until Mrs. Cake intervened.

"Hold this, sweet roll," Mrs. Cake said as she handed Fluttershy a new diaper, "and don't lose it now. We just might have to keep the big stinker in his messy diapers if we don't have a fresh one for him!"

Fluttershy stole a shaky inward gasp as her grip tightened around the folded diaper. Forcing Mcintosh to wallow in his messy diaper for a little longer if she lost the diaper? That would have been terribly awful, right? Right? No matter how unlikely losing something as big as an adult sized diaper, she couldn’t help but wonder if she did just that. She didn’t want that to happen, right?

“Oh shoot, have we really gone through another tub of wipes?” Mrs. Cake said tsking as she looked around the room, “you two sit tight while I go fetch another pack!”

Without another second to react, Mrs. Cake trotted out of the room, leaving the two diapered ponies alone. They sat in silence, awkwardly trying to avoid staring at each other. The subtle stench of Mcintosh’s messy diaper began to mingle with the ever present scents of baby powder and floral scented lotion. She never quite felt this way before. It was like fawning over an adorable baby animal mixed with falling in love with a handsome lover. It was innocent yet...incredibly erotic. And it all felt mutual.

“Sorry for the...smell,” Mcintosh finally spoke, breaking the heavy silence.

“O-oh, no no, it’s quite alright. I-I don’t mind, really,” Fluttershy answered with a stammer, hugging the folded diaper tightly. “Y-you uhm...do this often?” she then asked with a small voice. A voice so small that if she decided to fall back from the question she could easily brush it off with a quick ‘nevermind, it was nothing.’

“O-only when I’m able to,” Mcintosh answered after a long, embarrassing pause. Fluttershy’s ears tingled with red. Looks like he heard her after all. “Mrs. Cake only throws these...sort of things every couple of months...”

“A-and you always...wear?” Fluttershy dared another question, again in the same small voice.

“M-mhmm,” the stallion bashfully replied.

“A-and...use them?” Fluttershy almost sounded a bit excited as she spoke, eyeing the lump in Mcintosh’s diaper, “...like this?”

“I-I...like how it all feels...” he answered, sharing a similar hint of nervous excitement, “a-and I like...being treated like...this...”

“S-so having an accident in front of Mrs. Cake?” Fluttershy asked, her grip on the new diaper tightening, “i-it was just an act?”

“Sorta... Sh-she knows that I enjoy it...”

“A-and the...cage?” Fluttershy finally asked, noticing Mcintosh tense up at the mere mention of his chastity, “you like that too?”

“I-it makes Mrs. Cake happy to have it on to hold it over me,” he answered, not really being all too pleased about it.

Of course, Fluttershy assumed anything that prevented any stallion from just...touching themselves whenever they felt like it might have been bothersome. Although to have that special bit of pleasure locked away and held over him like a carrot on a string had some special allure to it. “Does she ever unlock you or...”

“O-only if I’m good...”

“Oh...” was Fluttershy’s response, followed by a long awkward pause as she blushed at the ground, “I-I think...I think you look really cute when you uhm...use your diapers...”

“Th-thanks...” Mcintosh said back with a surprisingly meek voice, “I-I think you look cute using your diapers too...”

"I'm back!" Mrs. Cake said in a singing voice as she slid back into the room with wipes in tow. "Sorry little Macky, it seems all we have left are lavender scented wipes. Mcintosh didn’t seem to mind. In fact, he seemed to smile a tiny bit at the embarrassing thought of smelling so girly.

Mrs. Cake went right to work on the diaper change by casually ripping off the four tapes that strained to keep the whole swollen thing wrapped around Mcintosh’s waist. Fluttershy stood by her side, diaper at the ready as she nervously squeezed the fresh diaper in her arms.

Even tucked away inside the plastic cage, the stallion’s well endowed girth looked so...big. It was no surprise he’d need such big diapers, Fluttershy thought to herself, big diapers for big babies. Maybe it was for the best to have his member locked safely away. He seemed so submissive and eager to please with the cage on. It was cute to think that everything he did, every good deed he performed, was an adorable attempt at winning Mrs. Cake’s favor so that she would grant him freedom from his chastity.

If it were up to Fluttershy, she probably wouldn’t have been won over so easily. At least that’s what she tried to convince herself of. She was starting to enjoy this little game. To have an obedient and strapping stallion eager to do whatever she asked him to. To humiliate him and tote him around like a trophy.

She could feel her face tingle and blush at the thought of it all. It was silly in a kind of way. To have her, meek little Fluttershy, lording over tough and stoic Mcintosh. It made her feel silly just thinking about it. Silly like a schoolgirl.

“Thank you for keeping a good eye on this, honey,” Mrs. Cake cooed, grabbing the diaper out of Fluttershy’s hooves and snapping the daydreaming pegasus out of her daze. “You’ve been very helpful so far. Maybe you can be my little helper for the rest of the day!”

She was kidding of course, but Fluttershy couldn’t imagine how many diapers Mrs. Cake had to change during one of these parties. And they were adult sized diapers too! Fluttershy could see herself changing a couple diapers, maybe, but being the sole diaper changer in a group of ponies who like spending their days drooling over themselves and acting like foals? She wasn’t sure she was ready for that sort of pressure.

“Hold this for a second, would you dear?” Mrs. Cake said as she hefted up the neatly rolled up diaper.

Not wanting to upset her host, Fluttershy quickly took hold of the diaper without fully realizing what she was holding. She immediately noticed a difference in weight between the freshly folded diaper and the old, well used one. There was a surprising amount of warmth coming from it. And the most subtle, earthy scents mixed with baby powder and lavender. Imagine just moments ago this big heavy thing was taped snuggly around Mcintosh’s waist as he waddled around, wagging his cute little bottom. She was starting to feel all tingly and silly again.

The rest of the diaper change passed like a dream as Fluttershy watched it in a half awake haze. Her mind still swam with silly little fantasies. Some possible, some impossible. Some innocent, some... not so innocent. It was tough to keep track of all these thoughts as the daydreams went into overdrive.

“Thank you for keeping an eye on that for us, honey,” Mrs. Cake chirped before turning to Big Mac who was now standing up freshly pampered, “well stinky britches, since you made the mess, you can throw it away.”

Big Mcintosh lowered his head shamefully as his embarrassingly messy diaper was handed off to him. He could only manage a very bashful glance over at Fluttershy who could only gulp quietly to herself as her face flared up. With a cloud of baby powder following him, he started to waddle off to the nearby diaper pail, which was already half full from the other party guests.

“No no, not here,” Mrs. Cake waved Big Mac off, “take that big icky thing out to the dumpster. I won’t have it stink up the place.”

The stallion gulped as his ears drooped. He whimpered something faint and squeaky in protest, but reluctantly waddled out the door with messy diaper in hand.

“I can clean up the rest of the mess, Fluttershy,” Mrs. Cake said, patting Fluttershy on the head, “you waddle on back to the party now, alright?”

“A-alright,” Fluttershy answered with a hasty nod. She skittered on out of the room as Mrs. Cake gave her an encouraging pat on the diaper. Even after the blush faded, Fluttershy felt all aflutter. She didn’t think her face would ever stop tingling.

Over by the other side of the room, Big Mcintosh stood at the back door, with his brown tinted diaper still firmly in hand. In a rare sight of things, he appeared nervous, fearful about stepping foot outside. Fluttershy could only imagine what was going through the worried stallion’s head. But at the same time she could only imagine how things would have been if she was the one giving him the orders. To have Big Mac whimpering up a storm and whining to her that he didn’t want to be seen outside wearing a diaper. To have her firmly telling him to do as she says or he’d get punished.

She shook her head out of yet another daydream before ponies started noticing she was staring off into space. There she went, feeling silly again.
