Cake Party

The master bedroom, Fluttershy noticed as they entered, had the same sort of feminine touch as the bathroom. The large queen sized bed that hugged the rightmost wall was fitted with matching bedsheets of calming shades of lavender and rose while the wide daybed near the opposite wall was fitted with floral prints and soft pinks. An open case of diapers and a set of changing supplies sat out in the open beside the daybed, seemingly put proudly on display for anypony to see.

"Carrot, would you help mommy and warm up bottles for everypony downstairs?" Mrs. Cake explained, gathering up the diaper changing supplies. "Have Cream Heart help you and bring three up here when you're done."

"Yes, mommy," Carrot nodded before disappearing out into the hallway.

With her diapered husband gone, Mrs. Cake turned to the freshly dried off girls with a smile. "Now then," Mrs. Cake clapped, “who's ready to go first?"

"Not it!" Pinkie exclaimed with a laugh. Of course it was pretty obvious that she was just being difficult for difficulty's sake.

"How about you go first then, Fluttershy," Mrs. Cake then said, "I'm sure Pinkie can behave herself just a little longer."

"No promises," Pinkie giggled.

Fluttershy complied and yet again found herself guided by the hoof to wherever Mrs. Cake took her. The day bed served as a spacious impromptu changing pad for now, something that Fluttershy imagined Mrs. Cake did quite often when the adult foals she watched needed changes. She must have changed diapers on a daily basis, Fluttershy assumed, there always seemed to be some grown pony nearby in dire need of a change. Why Carrot Cake alone must keep her busy on his own with his fussy demeanor.

A new diaper after a warm bath was refreshing to say the least. The crisp padding seemed softer against Fluttershy’s freshly dried fur, smelling just as sweet and clean as she felt. It all made a variety of feelings bubble up inside of her. It was almost paralyzing at times to comprehend the swirl of conflicting emotions she felt as the diaper was wrapped around her. Naughty thoughts fueled by sexual urges mixed with soft thoughts that were coaxed by comfort and littleness. She was happy to feel the snugness and security that came with the diaper, but also felt that tingling sensation in her loins that had been building up all day.

"Back," Carrot announced, waddling into the room with three bottles balanced on a silver tray on his back just as Mrs. Cake was finishing Pinkie's diaper change..

"That's a good boy," Mrs. Cake cooed happily, taking hold of one of the bottles, "did everypony else get fed?"

"U-uhm yeah...M-Ms. Cream Heart even let me practice...holding a bottle for her..." Carrot spoke with a little smile on his face.

"Busy boy," Mrs. Cake replied, "well you've earned your reward. Enjoy your bottle."

With a proud smile growing on his blushing face, Carrot happily carried the remaining pair of bottles to the other side of the room and handed one to Pinkie Pie. Pinkie happily nabbed the bottle and suckled on the rubber nibble as she playfully circled Carrot. She nudged and played with the stallion as she trotted around, bumping her padded rump into his side as she mischievously giggled. Carrot could only think to blush and shyly allow the flirtatious mare to dance circles around him.

Finally Pinkie nuzzled the underside of his diaper, sending a shivering blush across the stallion's face. A raging hard-on immediately grew, bulging out the front of his diaper. Already the poor stallion quivered with weak knees and longing eyes.

Fluttershy continued to stare until she was snapped out of it by the coaxing hooves of Mrs. Cake. With a gentle grip on the diapered pony, the motherly mare helped her onto the ground where she was lowered into Mrs. Cake's lap.

“Shh shh, quiet time, honey bun,” Mrs. Cake cooed as she popped the bottle into Fluttershy's mouth, allowing the pegasus to gently suckle down the sweet, warm milk, “just relax and enjoy your bedtime baba.”

Pinkie Pie and Carrot Cake meanwhile continued to play their naughty games, feeling each other up and sensually kissing each other all over. Pecks on the cheeks were responded with wet smooches on the neck while diaper pats were replied with deep kisses on the mouth and moans. For a long while, the only sounds heard in the peaceful room was quiet moaning, soft crinkling, and Fluttershy’s gentle suckling.

Carrot Cake seemed the most vocal of the group. His squeaky groans of pleasure could be heard more often than not. He lustfully clamored over Pinkie Pie, kissing and twisting around her in sweet embrace. He focused a lot on grinding up against the other pony, pressing his tenting diaper firmly against her as they made out. He was like a horny teen in bed, almost quivering as he moaned.

Suddenly Carrot's murmurs turned into sharp and heavy breaths until finally he let out a whimpering moan. He began to squirm as his waist pathetically twitched up into the air. On his face was a flash of pleasure, followed shortly by bliss, and seconds later regret and worry.

“Tsk, Carrot,” Mrs. Cake scowled, “don’t tell me you finished already!”

“I-I...I...got carried away,” the stallion shamefully answered.

“I would say so,” Mrs. Cake shook her head, “and you didn’t even wait for Pinkie Pie.” The pink pony responded with an exaggerated and playful pout.

Carrot Cake shamefully lowered his head, his body quickly cooling off from the heated orgasm. "I-I'm really really sorry, mommy," he spoke with a little voice, "i-it was an accident..." He truly felt awful for his shameful performance, that was obvious. And that just seemed to make him appear all the more cuter.

Mrs. Cake only scowled at the diapered stallion and tsked with disappointment. “Pinkie," she finally said, "be a dear and grab Carrot's little toy. It's in the usual spot.”

“C-Cup Cake!” Carrot Cake whined.

“Hush,” Mrs. Cake snapped before turning back to Pinkie, “might as well grab the suppositories from the bathroom cabinet while you're at it. If he's going to keep having accidents in front of us, they might as well be entertaining."

“Can do!” Pinkie Pie exclaimed as she hopped to her feet with a happy sprong. “Come on, baby, we’ll get you ready!” With a meek and submissive nod, Carrot Cake followed Pinkie Pie back out into the hall and out of sight.

"Sorry you had to see that, little Shyshy. Carrot's always getting over excited when he's playing with Pinkie," Mrs. Cake explained, "but I'm betting you're loving the show so far."

A blush flushed Fluttershy's face as she couldn't help but nod. Truth be told she was enjoying the show immensely. It was like her own private performance that played out in front of her. Watching Pinkie and Carrot fondle each other like a pair of horny teens was exciting and having Mrs. Cake ordering Carrot around was just icing on the cake.

Carrot Cake returned a few minutes later, trying his best to shrink behind Pinkie Pie who showed him off with pride. He was now sporting a powder blue penis strapped over his diaper. The strap-on was made of a firm material with enough detail in its lifeless imitation that it almost resembled the real thing save for the strange color. The whole apparatus was bound over his diaper with a series of black straps that ensured that the blue penis was properly positioned right over his padded crotch.

“He’s all ready, auntie!” Pinkie so proudly exclaimed, handing off a small white container of suppositories to the other mare.

“Alright, Carrot, bend down for mommy,” Mrs. Cake commanded before she turned her attention to the little filly quietly laying in her lap, "Now Fluttershy, Auntie Cake needs to take care of something real quick. Can you be a good filly and hold onto your bottle until I get back?"

With her cheeks flushed in rosy red, Fluttershy nodded and raised her hooves to take hold of her bottle that still sloshed with a healthy amount of milk. She watched as Carrot crouched in front of her, his crinkly diapered rump raised high up in the air so that his orange tail flagged highly into the sky.

Carrot’s tail tape was undone and the diaper slipped down his legs, exposing his baby powder stained bottom to the open air. Whenever he fussed just a little too much, Mrs. Cake was there with a swift spank on his thigh and a sharp and commanding “hush!”. Fluttershy sucked in an extra large gulp of milk as her cheeks flared up. She couldn't help but picture herself giving Carrot's powdered bottom a firm spanking. Or, for that matter, having HER bottom spanked. What if Big Mac needed to be spanked? Would she pull his diaper down and spank his powered butt too? Was his butt as adorable as Carrots?

As these thoughts rushed through her mind, she watched tentatively as Mrs. Cake popped open the lid of suppositories and rolled one out onto her open hoof. With expert dexterity, she slipped the small blue pill into Carrot's tail hole, causing the stallion to gasp and groan in displeasure.

“Now you give Pinkie Pie all your attention, alright Carrot?” Mrs. Cake said, pulling Carrot Cake’s diaper back into place and taping it snuggly. “It's only fair after you so rudely finished before her.”

“Y-yes mommy,” Carrot answered with a small voice.

Fluttershy watched the whole thing from her spot on the floor, taking in big quaffs of milk as her eyes grew wide. Watching the submissiveness of the stallion made her crotch tingle and hearing Mrs. Cake's commanding tone made the front of her diaper feel muggy. In a feat of mental gymnastics, her deviant mind imagined herself simultaneously taking on the role of the submissive and the dominant. To be in such a commanding and authoritative position. To be commanded to use her diapers whether she wanted to or not. Her mind teemed with sexual thoughts, each one played out slowly so that she could savor every last, breathtaking sensation. And with each arousing thought, came another hungry suckle of milk.

“Take it easy, sweet roll,” Mrs. Cake cooed, taking hold of the bottle once again, ”you’ll get a tummy ache.”

Snapping her charge out of her milk fueled fantasies, the motherly mare snuggled back under Fluttershy, resting the pegasus’s head in her lap once again. Meanwhile Fluttershy so desperately tried to hold back the intrusive thoughts and slow down her suckling, but her face continued to burn warmly and her body continued to tingle all over.

“Wouldn’t want to end up like little Carrot over there, would we?” Mrs. Cake continued as she gave Fluttershy’s soft furred tummy a pat.

Fluttershy felt her face blush and get all tingly again. She looked back at Carrot who already appeared uneasy from the suppository. For a passing moment, her mind fantasized about being in Carrot’s position. She wondered how a messy diaper felt and if she’d even find the courage to do something so demeaning. Would she be able to do it when the time came? Would she have to be forced into it like Carrot Cake? Already filled to the brim with steamy, sexual energy, she tried not to ruin the mood by imagining such things. Instead she watched the erotic scene unfold in front of her.

Carrot Cake laid on his back as Pinkie mounted the diapered stallion with giggling vigor. The light blue strap-on stood firmly upright on top of the stallion's diaper, subtly pressing down on his limp penis that shrunk inside its sticky insides. A deep red blush burned his cheeks as he worried about what was soon to come.

Pinkie meanwhile savored her time on top of Carrot, hardly paying much attention to the stallion's growing discomfort. First she started to rub the front of her diaper against the strap on, allowing the firm dildo to mold its length into the fluffy - and mildly soggy - padding. She thrusted her hips down against Carrot as the dildo was squeezed inbetween the two, all the while moaning loudly and lustfully. Once she was good and warmed up, she opened a leg gatherer of her diaper and guided the dildo into its warm insides.

The direct touch of the dildo against her already moist pussy sent shivers down Pinkie’s spine. Already teeming with excitement and libido, Pinkie quivered and twitched as she resisted every urge against going down slowly. Inch by inch, she lowered herself onto the firm dildo, allowing long and loud moans to ooze out of her drooling mouth. She reveled in the feeling of fullness that the dildo provided, a rare treat she normally never felt when playing with Carrot.

Steadily and rhythmically, she rode the stiff toy while idly nursing her bottle. Between moans and pants, she playfully gummed at her half full bottle, taking in quick squirts of milk to cool her heated body.

Meanwhile Carrot struggled with dealing with the growing pain that was bubbling in his gut. The stallion would wince with every bounce, as the shock rattled the delicate control he tried to hold over the inevitable. Every passing second left his bodily control weaker and weaker and with every bounce he could feel himself closing in on the point of no return.

Finally his eyes shot open wide with desperation. “W-wait...P-Pinkie...” his voice was weak and strained at this point. Sweat beaded down the poor stallion’s face as he struggled to keep it all together. But Pinkie Pie was hearing none of it. Too wrapped up in her feverish bouncing, she was more concerned with her own orgasmic climb to pleasure than the battle Carrot was very quickly losing.

And then, in one pathetic little whimper, Carrot Cake lost all control of his bowels. His hind legs wimply wiggled underneath Pinkie as a liquidy gurgle rumbled his diaper. The runny filth that had been building up in his gut finally dropped into the waiting diaper, bellowing out the pristinely white padding and staining it with an embarrassing hue of brown. Weak, hasty grunts pushed the rest of the mess into the diaper, only to immediately get pressed under his weight as Pinkie continued to bounce on top of him. Once he started, he could do nothing but allow the rest of his humiliation pass as his diaper grew heavier and heavier underneath.

Carrot was left shamefully exhausted, his body tired from holding back the painful swell in his belly only to have it all lost in an instant. He grew quiet, too embarrassed to even look his mommy in the eye during these trying times. The subtle squishing sounds, not to mention the very childish scents that seeped out of his diaper kept him still. The only thing he could do was quietly suckle on his milk bottle and wait for Pinkie to have her fill.

Pinkie meanwhile didn’t lose a beat, not even slowing down as Carrot made a mess of things. She might not have even noticed him filling his diaper deep in the throes of her sexual bouncing. She continued to moan and pant loudly, enjoying every inch of the powder blue dildo as it slid in and out of her slick pussy.

Fluttershy stifled a gasp as she watched the whole thing with wide eyes. The desperate struggle for control, the weak pleas for mercy, and even the subtle bulging that ballooned out Carrot’s diaper. It was just like when she watched Big Macintosh soil himself earlier, a memory she fondly recalled. Only now she was keen enough to pay attention to every minute detail that unfolded in front of her. She felt the same tingly, blush filled response bubbling inside her as well. Not to mention that familiar hot and humid feeling in her diaper. were all details the meek pegasus focused heavily on.

She didn’t quite know how long she stared at the sight, but after a while she was snapped out of her staring contest with Carrot's bulging, brown diaper when an invasive hoof pressed into her warm padded crotch.

“Enjoying the show, little Fluttershy?” Mrs. Cake whispered as she kept up the rhythm, rubbing deep and sensual circles into her diaper.

The motherly mare dug deeper into Fluttershy’s warm diapered crotch, driving the young pony crazy. The milk bottle did only so much to muffle the long, drawn out moans that squeaked out of the pony's mouth. She very quickly became quivering puddy in the mother mare’s hooves and could feel her inhibition slip. As Pinkie continued to bounce on Carrot’s tireless dildo, Mrs. Cake picked up the pace and rubbed fast and deeper into Fluttershy’s moist sex.

"Such a vocal little pony," Mrs. Cake chuckled, "crinkling and squirming up a storm in her little diapers. I bet my little Shyshy would just love to join in, huh?”

The sex crazed side of Fluttershy wanted to scream out a desperate “yes!” But whatever fragments of self control she could conjure up kept her bottle pressed firmly against her muzzle, plugging up any embarrassing pleas that came dangerously close to slipping out.

“I bet if you asked extra super nicely, those two would let you get all stinky and sticky with them,” Mrs. Cake continued to whisper, “what are friends for after all.”

She was too embarrassed to admit it, but Fluttershy now knew how lewdish and perverted her thoughts had become! She wanted to wear diapers and wet them and waddle around in them and have sex with a hot stallion in a diaper! Yes! And be forced to fill her diaper completely and be humiliated in front of all her friends and be told she’s nothing but a baby who can’t have sex outside her diapers! She wanted to wear diapers forever! Yes, she wanted all that! She wanted that!

To put the final cherry on top, Mrs. Cake leaned in close, whispering with a sweet, sensual voice into Fluttershy’s blush filled ear, “betting Little Macky would enjoy himself too.”

With a shocked gasp, Fluttershy was sent over the edge. Her eyes shot open and her thighs squeezed together tightly as a climactic sensation sent her whole body into twitchy convulses. Any moans or panting the yellow pony could manage to make during her throes of pleasure was overpowered by Pinkie Pie's moans as she continued to ride Carrot’s strap-on with unrelenting energy and vigor.

Fluttershy squeaked and whined as her legs compulsively wiggled and squirmed. She might very well have slid out of Mrs. Cake’s hold if the older mare wasn’t holding her steady with her hoof still wedged between Fluttershy’s thighs.

"Oooh dear," Mrs. Cake's voice teased and taunted the exhausted pony, "I bet that felt really good, huh? And with that big diaper on there isn't even a mess to clean up. Lucky you!"

The praise left a genuine smile on Fluttershy's face as she rode out the blissful climax that felt as if it had been building up all day. Safely nestled in Mrs. Cake’s lap, the diapered pegasus squirmed and weakly kicked as she reveled in the afterglow. Her thoughts returned to normal as the burning sexual urges subsided for now. She felt so content in the motherly mare's arms. She felt like she could just suck on her hoof and fall asleep right there.

"I'll be back in a moment, you two," Mrs. Cake called out to the other ponies, her words only barely audible to Fluttershy, "I think it's naptime for good little ponies." Delicately, she pulled her charge off the ground, plucking the empty bottle out of the peagsus's mouth before helping her out of the room.

Fluttershy was floating. Still dazed from her bliss filled climax, she struggled to walk straight. The short walk down the hall proved to be quite the challenge for the dazed pegasus. It took Mrs. Cake's guiding hoof to keep the dazed pony from tripping over her own sluggish feet.

Eventually the pair entered a room that appeared to be a nursery, only better equipped to accommodate older ponies. The whole room was cloaked in a starry nightlight that casted twinkling stars on all the walls that slowly rotated around the room. Two large cribs sat across from each other on the far end of the room, each one with clean bed sheets neatly made inside.

The cribs looked like a cozy spot to spend the night in. A cozy spot to end a cozy and exciting day of new experiences. It had been a big day of learning new things about herself and having fun, especially with Macintosh. Macintosh!

"W-wait! Where's Big Mac?" Fluttershy suddenly exclaimed.

"Missing your little friend, huh?" Mrs. Cake replied, "don't worry, he'll be in soon. Getting close to his bedtime too." She tucked the yellow pegasus in tightly, wrapping her up in a nice warm blanket. “He’ll be sharing your crib for the night. Pinkie gets her own crib since she tends to leak. Even through her double night time diapers!” Mrs. Cake chuckled, "you don't have to stay up for him, don't worry. You had a big day today."

"I...had a lot of fun playing with him today," Fluttershy admitted.

"I know you did, sweetie. He really likes you, I can tell," Mrs. Cake winked.

"Will he...have time tomorrow to play?"

"Of course, sweet roll, tomorrow's a whole new day," Mrs. Cake said, giving Fluttershy's forehead a sweet and delicate kiss, “good night, my little diaper butt.”

Tucking the little, yellow pegasus in for the night, Mrs. Cake tip toed out of the room. The faint blue glow of the nightlight kept the room cloaked in twilight as Fluttershy snuggled into her bed for the night.

Cuddling up in her mound of soft blankets, she let out a big breathy sigh. What a day. What an exciting and eventful day! In all her life she never imagined herself in such a situation. To tote around in diapers. To play with foal toys. To be treated like a little filly. She never thought she'd ever feel so vulnerable, so pleasant and tingly, or...turned on. It almost all felt like a dream if it wasn't for the sticky warm spot that hovered around the crotch of her diaper.

And tomorrow was a new day indeed! She couldn't imagine what she'd get herself into after a refreshing nap. She really wanted to stay up to see Big Macintosh come to bed. She couldn't exactly explain why or what she'd even do when he got here. Maybe they'd cuddle? Or...did she just want someone else in her crib to keep her company? She wasn't really sure. And quite frankly she was too tired to think.

Another yawn interrupted her train of thought, reminding her just how tired she was. Sleep was the more important thing right now. Sleep and then tomorrow was a whole new day.
