Cake Party

Fluttershy shrunk back as Mrs. Cake promptly answered the call. The motherly mare brought with her Big Mcintosh who was sporting a very very soggy diaper and a green pacifier. “Oh Fluttershy, did you have a little accident?” she cooed at the pegasus, running a hoof across the edge of the diaper to check herself, “well not to worry, me and little Macky were just about to go and get changed. Isn’t that right, Big Mac?”

The tall stallion just blushed, nodding meekly as he tried to avoid making eye contact with the other ponies. The apparent embarrassment only drew attention to his diaper, which was practically soaked through and through. It put Fluttershy’s meager ‘accident’ to shame.

“Come along then,” Mrs. Cake chirped with a beckoning hoof, “I’ll get you both changed while I’m at it. Pinkie if you could be so kind as to be mommy’s little helper.”

“Can do!” Pinkie exclaimed with a bounce.

With blush filled cheeks, Fluttershy was pulled up to her feet and nudged away from her spot on the floor. Pinkie Pie happily bounced behind the group as Mrs. Cake guided the two soggy ponies across the kitchen area where a side room could be seen.

Mrs. Cake, Fluttershy, Big Mcintosh, and now Pinkie all filed into a side room that connected itself to the storefront. It appeared to be some sort of living room or parlor. An auxiliary living space to entertain guests or quietly read a book. A couch in the middle served as the focal point of the room. Surrounding it were end tables on either side and a coffee table in front of it.

For today, everything was pushed to the side and the couch was pushed up against the far wall, opening a wide open space on the soft carpet for any number of activities. A large changing pad laid across the floor, large enough to comfortably fit two grown ponies on top of it. A nearby shelf contained a box of changing supplies as well as a stack or two of neatly folded diapers. It seemed that Mrs. Cake had planned this party out well and this was to be the designated diaper changing room. Such a concept made Fluttershy blush.

“Alright, sweet things, on your backs!” Mrs. Cake sang, nudging Fluttershy and Big Mcintosh forward toward the changing pad.

Mcintosh took the lead and waddled ahead of Fluttershy with his overly swollen diaper in tow. The urine soaked thing that hung on his waist sloshed and crinkled obnoxiously with every step he took. Fluttershy couldn't help but blush as she stared at the yellow stained garment. She could even smell the faint stench of urine emanating from it. A smell that fiercely competed for dominance with the stallion’s natural masculine musk.

“You too, Fluttershy. Can’t have Little Mac be the only one getting a diaper change. He’d get all embarrassed,” Mrs. Cake cooed as she pushed Fluttershy the rest of the way onto the mat, even going as far as to helping her lower herself onto her back.

The changing pad had a slight cushion to it and was made of a slick, waterproof material that crinkled under the two ponies’ weight. It chilled Fluttershy’s back as it made contact with her soft fur and made a tiny, shaky gasp slither out of her muzzle.

“There’s a good girl,” Mrs. Cake cooed as she lowered herself to the ground, “Pinkie, be a dear and grab me some supplies for the foals.”

“Okie dokie!” Pinkie cheered before bouncing over to the shelf and assembling the needed supplies.

“You’re first, soggy britches,” Mrs. Cake said to Big Mcintosh as she slid in between the stallion’s legs, “wait any longer and this thing might burst!”

Big Mcintosh obediently followed Mrs. Cake’s lead and spread his legs further apart as if this was all so routine. His yellow diaper ballooned outwards around his crotch, nearly dwarfing him in size.

Fluttershy couldn’t quite look away from the sexy stallion who laid beside her. In a weird way, the soaked diaper and pacifier made Big Mac look...more attractive wearing them. Maybe it was her own diaper that was enticing this thought. Maybe wearing a wet diaper was the least of her problems. Maybe she was staring at his diaper just a little too intently.

With showy flare, Mrs. Cake pulled away the diaper’s tapes, loosening the sodden thing around Big Mac’s waist. Surprisingly enough, opening the diaper revealed not a throbbing girth that Fluttershy fantasized about, but instead a bright blue hunk of plastic in the smoothed out shape of a softened member.

Pinkie Pie was quick to notice Fluttershy’s puzzlement. “Mrs. Cake makes all her stallions wear chastity cages so they behave,” she giggled, eyeing at Big Mac’s tightly bound up cock.

“Helps keep their hooves off their diapers too,” Mrs. Cake chuckled before grabbing at the cage and jiggling it, “isn’t that right, Little Macky?”

Big Mcintosh whimpered up a storm, but still found the strength to nod. His body was tensed up into knots as a desperate burn of desire flared up his cheeks. With his bound penis exposed out in the open, all he could do was squirm and let out muffled huffs behind his pacifier. His cock remained achingly soft behind the plastic restraints, occasionally throbbing painfully against the cage.

“D’aww, look at his little squirmies,” Mrs. Cake cooed as she popped open a plastic tub of baby wipes. “Maybe if you behave yourself, I’ll unlock you later."

Big Mcintosh whimpered some more, but nodded submissively. His cheeks still burned with a red heat, but outside of a fussy wiggle he did with his legs, he did nothing to voice his pent up frustrations.

“That’s a good boy,” Mrs. Cake cooed some more, “now let's get you cleaned up.”

Humming a calming little tune, Mrs. Cake cleaned Big Mac’s crotch with the cold scented wipes. The stale, pungent scent of urine was slowly replaced with the gentle and fresh smell of cucumber and melon. One by one the used wipes were all gathered into a little pile in the middle of the open diaper before it was all wrapped up into a tight ball.

A new diaper was fanned out in the air with showy flare before being effortlessly slid underneath the stallion’s butt. Mrs. Cake hiked Mcintosh’s legs up into the air, possibly longer than she needed to, before slowly lowering them back down with the diaper in place.

Next step was the baby powder which emanated a soft, flowery scent. The white powder was so delicately sprinkled onto Mcintosh’s crotch before being lovingly rubbed in by Mrs. Cake’s caring hoof. She even made sure to give his firm rump a generous powdering and finally gave his belly a little sprinkling before pulling the whole diaper up between his legs.

The end result was a crisp and expertly taped diaper that was not too tight and not too loose. Big Mcintosh fussed a little more as his bound up member was once again covered up by a diaper, but behaved himself. Mrs. Cake finished the diaper change with a gentle tummy rub that turned the stallion’s fussy scowl into a happy smile.

“There’s a good boy,” Mrs. Cake cooed before sliding her way down the bench and in between Fluttershy’s legs. “Okay Fluttershy, now you,” she said as she rubbed her tummy, “such a good girl being so patient!”

A shy smile grew across Fluttershy’s face as she blushed at the lovely treatment she was receiving. Continuing her humming tune, Mrs. Cake so casually ripped the tapes off of Fluttershy’s diaper, releasing the pegasus of the muggy warmth that surrounded her crotch. A rush of cold air flooded the inside of the diaper, making Fluttershy shiver weakly.

Fluttershy was much too embarrassed to even look the motherly mare in the eye and Mrs. Cake seemed to pick up on that. Despite all the fun she had with Big Mac, Mrs. Cake changed Fluttershy in an oddly routine manner. With no sexual subtext or theatrical flare, she had the old diaper pulled out from under Fluttershy, wiped her clean, slipped a new diaper under her, and powdered the area liberally without losing a beat of the rhythm. It was a task she had done a dozen times today already and it showed.

Hiding her blush covered face behind her forehooves, Fluttershy allowed her body to be manipulated and moved about as the old, heavy diaper was pulled away and replaced with a fresh, fluffy diaper. As exciting - and perhaps erotic - as it was to watch Big Mcintosh getting his diaper changed, the humiliation of being in such a submissive position made her feel much too vulnerable to enjoy it. She felt put on the spot, yet strangely comforted by how tenderly Mrs. Cake handled it all. She felt like everypony was watching her, yet

Before she knew it, the diaper change was over and she found herself wrapped in a freshly powdered and incredibly soft diaper. Spending so long in a soggy diaper almost made her forget how euphoric a fresh diaper felt. It was like she was being hugged by a cloud.

“There we go! That wasn’t so hard, was it?” Mrs. Cake said so softly as Fluttershy bravely peaked out from behind her hooves at the end of it all.

Big Mcintosh was already back on his feet, stretching a tiny bit as the stiff material of the fresh diaper softened up and molded around his toned backside. Fluttershy’s attention slowly shifted over to the masculine stallion as she watched him waddle around the room and exchange a couple whispered words with Pinkie Pie.

“Up we go!” Mrs. Cake exclaimed, taking Fluttershy by the hooves and helping her up.

“Wasn’t that the funnest!?” Pinkie exclaimed as she bounced over to the pair, “diaper changes are the BEST!”

“Speaking of diaper changes,” Mrs. Cake said, now running a hoof across Pinkie’s diapered crotch. “Hm, only a little wet,” she mused mostly to herself, “we can probably wait till after snack time, hm?”

“Might need a bath after snack time,” Pinkie Pie giggled playfully with a little blush in her cheeks.

“Well, we’ll cross that bridge when we get to it,” Mrs. Cake nodded before turning to the other two. “Alright, off you go, my little ponies! It’s almost snack time!” She encouraged the group of diaper ponies out with a couple pats on the butt.
