“U-uhm Mrs. Cake?!” Fluttershy practically yelled out with a forehoof flung out before her. Only a mere second later she immediately pulled it all back, “c-could you maybe...uhm...NOT change Mcintosh’s diaper?”

“Oh?" Mrs. Cake answered, her hooves hovering inches away from the straining tapes of Big Mac's diaper. "Whatever for?”

Fluttershy nervously fidgeted with the key around her neck, “I-I uhm...w-want him to uh...earn it...Please?”

Mrs. Cake paused for just a moment, but as all of it clicked into place, the older mare smiled impishly. “Oh is that so?” she finally said with a grin as her hooves pulled away from Mcintosh’s diaper, “alright, sweetie, just because you asked nicely.”

“What?!” Mcintosh exclaimed with a groan, “b-but M-Mrs. Cake!” His voice rose into a squeaky whine. A most unexpected tone from such a mature looking stallion.

“Don’t fuss, Little Mack! You KNOW very well the responsibility you entrusted Fluttershy with when you gave her that key,” Mrs. Cake chided, “she calls the shots and she asked that your diaper not be changed.”

“B-but it’s so...” Mcintosh’s voice got smaller and as the authority of his words got weaker, “so...full...” He said those last words with such a tiny voice that it was barely audible.

“I’ll give you two some alone time then,” Mrs. Cake said, packing up the changing supplies, “call me if you need anything, alright Fluttershy?”

“Th-thank you, Mrs. Cake,” Fluttershy replied with a furious blush warming her cheeks.

And just like that, the two diapered ponies were left alone in the nursery. Fluttershy with her freshly powdered behind enjoying the softness of a new, crisp diaper. And Mcintosh who pulled himself off the table with a defeated slump, his brown stained diaper bulging and sagging out the back. He looked cute in such a state. Almost like a pouty toddler being told to put away their toys for the day.

Fluttershy felt a quiver of excitement swell inside of her as she watched the stallion. But at the same time, a pang of worry stirred in her chest. “I-I’m really sorry for that,” she immediately began to backtrack, feeling an itch of guilt about the whole thing, “i-if it’s really a big problem for you, I-I can-”

“No,” Mcintosh interjected, “you have the key. You call th’ shots.” He then looked up to Fluttershy and for a few short seconds, their eyes locked and sparks danced in the air between them. “Ah want this. A-ah want you to keep going...”

The spark turned into heat as the two ponies’ faces flared up with an aroused blush. Their breaths became erratic and shaky and their heartbeats quickened. Keep going, their eyes said.

"O-okay," Fluttershy managed to stammer out.

So this was it. She had him where she wanted him. Now what? Before now she could think of a dozen and a half scenarios that she wanted to play out with Mcintosh. All that time she spent daydreaming and lusting over the stallion from a distance gave her mind ample opportunity to conjure up lewdish and silly ideas that she only dreamed could come true.

But now she was here. She got what she wanted. A needy diapered stallion who was into all of it as much as she was. Now that the opportunity finally struck, her mind was paralyzed with choice. What if he didn’t actually like the stuff she did to him? Did that matter? What if he got too upset or angry? Did THAT matter?

Leap of faith, Fluttershy. Leap of faith.

"A-alright well first...I uhm, n-need to give your diaper a proper check," she finally said, starting with something so seemingly small. It almost felt like a trifle thing to ask for and yet her cheeks burned with a bright pink. She spun her hoof in the air for added flair, "t-turn around...please...honey." The cute little nickname at the end made her tongue tingle.

Being a good little colt, Big Mcintosh turned on his heels, spinning his thickly diapered butt closer to Fluttershy. A strong whiff of baby powder and earthy filth flew past her face before the stallion’s diaper landed firm, inches away from her muzzle. The concoction of scents called attention to itself almost as much as the deep shade of brown that now wrapped around the better part of Big Mac’s backside did. Musty urine mixed with sleepy lavender mixed with sweetly sour stink.

And despite all that, Fluttershy didn't feel the revulsion she assumed she was expected to feel. The mixture of smells didn’t make her sick or make it hard to breathe. It wasn’t a bad smell, not entirely. It was kind of a cute stink. An adorably stinky diaper wrapped around a stud of a stallion.

After a few moments of stillness, the yellow pegasus leaned in and dared to touch the soiled thing. It started with a tiny, tentative pat which was followed up by a very light press. Then after that, she allowed her hoof to rest on the bloated backside of the stallion's diaper. The diaper was squishy and pleasantly warm. It was like resting her hoof on top of a smelly, plastic covered electric blanket. The warmth. The crinkling. The way it molded and moved around like smooth clay. It felt soft. It felt disgusting. It was a feeling that she couldn’t get enough of! It made her chest feel silly. It made her nose curl in distaste. It made her feel tingly and aroused.

It was then she felt brave enough to experiment with a swift smack, causing Mcintosh to quietly yelp with surprise. It was a light smack, barely making any impact or even an imprint in the yellowish brown material that ballooned behind him. And for a brief instant, Fluttershy gave pause. The single spank made her hoof tingle and her heart quiver. She looked at the hoof with newfound excitement that was bubbling to the surface as a tiny smile.

So shortly after the first pat-spank, Fluttershy dared another, soliciting a similar response from Mcintosh. She then dared another, smacking harder and pressing deeper into the pillowy, plastic material. Then another and then another.

It was tough to say what her end goal was with those pat-spanks. It wasn’t to punish the stallion for doing exactly what he was told. It wasn’t to shame him by reminding him of the mess he made. It wasn’t malicious or painful. It was just...she couldn't quite explain it. She just couldn’t quite get enough of the pressed pat-spanking. It was arousing in a way. Empowering in another way.

She imagined this was how Mrs. Cake felt when she was doling out punishments for misbehaving foals. Roles of power often mixed in the real world, but there was a finer definition in situations like this. Those in charge spanked, those who followed got spanked. If she wasn’t such a nervous little filly she imagined she’d enjoy the role of spanker quite a lot.

"Naughty diaper colts deserve spankings over mommy's knee," she imagined she'd say, pulling Mcintosh away from whatever he was doing to give him a spanking.

It wouldn't matter if he was dry or messy or wearing a diaper at all, if the mood struck her, Fluttershy imagined herself pulling the stallion over her lap to give him a firm spanking. And Mcintosh would cry and cry and cry. Writhing under his mommy's hold, squirming feebly in her lap. He'd fuss, but dare not wiggle his bottom out of the way.

In reality though, the stallion just stood there quietly with his head low to the ground. He nibbled on his lower lip to muffle hushed moans that slipped through his muzzle with each squishy smack. Not crying or whimpering like Fluttershy had kinda sorta hoped. Just privately bracing himself for each soft sequential spank that squished his shameful stink oh so subtly against his sensitive backside.

After all of Fluttershy's daydreaming, she realized she was starting to leave quite the depression in Mcintosh's diaper. The lumpy mush had become flattened after her ten or twenty or fifty-some-odd pat-spanks.

"S-such a...n-naughty colt," Fluttershy said softly, practically muttering the tingling words.

Mcintosh responded in kind with a louder moan and an obvious squeezing of his thighs. Even tightly bound behind his chastity cage, Fluttershy could only imagine just how desperate he was getting. To be teased and taunted and played with. She figured if she was in his position she’d be bawling her eyes out, begging for any kind of release. And yet, the stallion maintained his composure, aching and whimpering, but behaving himself like a good colt.

Wanting to feel more, Fluttershy slid a hoof across the length of the diaper, smoothly running it from the base of the stallion's tail to his padded plastic bulge in the front. She could feel the warm, squishy clay inside the diaper mold around her as she nudged the whole mess a tiny bit closer to the front. Mcintosh’s plastic chastity cage felt like an unnatural bump among the sea of swollen, urine soaked padding. It felt naughty knowing that the bulge locked away the stallion’s well endowment and that it grew more desperate with each tease.

“Poor thing,” Fluttershy said, mostly to herself, “l-locked up and unable to...p-play with...me.” She wasn’t going to win any awards for her pillow talk, but still the words made her giddy like a schoolgirl. It was like playing pretend as a little kid, but more exciting and taboo. She found that she really liked teasing!

However she still felt a burning pang of guilt weigh her down as she made such selfish decisions. Her empathy prevented her from ignoring how pent up Mcintosh must have been feeling. Surely it was starting to hurt being teased like this and being physically unable to do anything about it.

But then she glanced down at her shiny key necklace. Mrs. Cake’s and Cream Heart’s advice echoed in her head. She had the key so she called the shots. He had to earn it. He’d just have to stay in his stinky diaper for a little longer until SHE was satisfied.

“O-okay uh...colty,” Fluttershy struggled to say that without a little silly giggle, “lay down on your back.”

Despite how bottled up he was feeling, Mcintosh swallowed a pathetic whine as he did as he was told. Carefully he rolled onto his back, gingerly paying close attention to his squished, messy diaper that hung grossly between his legs. His stinky backside was expertly handled to ensure that it was the last thing to touch the ground, to reduce risk of blow out, Fluttershy guessed. Fluttershy then climbed over him, her own diaper - pristine and white - hovering over the stallion’s face.

With shaky legs, she lowered her crotch, balancing it right on the tip of Mcintosh’s nose. Much like her tentative pat-spanks moments ago, the timid pegasus started things out with an experimental feel, pressing her cushy diaper front into Mcintosh’s muzzle for only a second or two. The pillow-like material crinkled as it creased over the stallion’s muzzle. The prod through the diaper could be easily felt by her sensitive sex, making her nibble on her lip, squeak, and quickly raise herself up off of the stallion’s face shortly after.

Lowering herself again, she dared another press, sending cool shivers down her spine. And then another, followed shortly by another. The prods turned into presses and promptly the presses turned into full on grinding. Soon the primal pursuit for pleasure quickly took over the diapered pegasus and she began to bear down on the stallion’s face, grinding her pampered pussy firmly against him.

Between thrusts, she’d peek through squinting eyes to see Mcintosh’s diaper laying inches under her. Her nose tickled at the smell of the fragrant, yellow diaper, keeping her in the lewdish mindset of a naughty diaper filly.

All Mcintosh could smell was baby powder and the nursery scents infused deep in the padding of Fluttershy’s diaper. The smell, however, was incredibly intoxicating. As Fluttershy humped and grinded against his face, Big Mac could only lay there, breathing in deeply the mare’s scent that fully encompassed his snout. Every now and then he would moan, sending wonderful vibrations up through Fluttershy’s diaper.

Rhythmic crinkling accompanied Fluttershy’s dry humping. Her pussy grew moist with pleasure as every deep, sensual rub drove her crazy with pleasure. The smell of sex mixed in the air with the stink of poopy diapers as diapers squished and pressed about. The sound of moans mixed with the sound of squishing and crinkling.

Finally she reached her tipping point and in the final throes of her orgasm, Fluttershy lowered her head into Mcintosh’s warm diaper, pressing her snout deep into the squishy, pillowy material. Filling her nostrils with the stinky scent amplified her shivering climax. Her legs quivered, her cheeks flushed with red, and her sex slick with her own juices. No matter how much she squirmed, her heated diaper crotch remained firmly planted on top of Big Mac's snout. One final, encouraging moan from the stallion rumbled her diaper as the front became hotter and more humid than ever before.

Her legs finally gave out after the intense thrusting session and she plopped on top of the large stallion. Big Mac’s full diaper served as a convenient pillow for the recovering pegasus and she reveled in the subtle warmth that emanated from the musky padding. Meanwhile Mcintosh blushed underneath Fluttershy’s padding. No matter how he tried to breathe, the overpowering scent of baby powder filled his lungs. It was like the smell was inescapable while he remained pinned underneath the petite padded pegasus.

After her break in blissful afterglow, Fluttershy eventually found the strength to once again pull herself off the broad shouldered stallion. For a moment their eyes met and in her post-orgasm clarity she couldn't help but blush. Big Mac only smiled a polite smile, hardly minding the fact that she used him as her own personal breeding stand. Like the well behaved colt he was, he took it all in stride.

Once again Fluttershy glanced down at her key necklace that now dangled and shined in the dim nursery light. Mcintosh's good behavior wasn't lost on the yellow pegasus. He was so well behaved throughout all that, even when she pleasured herself while neglecting his own comfort. She could have easily unlocked him for being such a good boy. He had certainly earned it after that.

Or...she could tease him for just a little while longer.

With this new mischievous thought in mind, Fluttershy scanned the room around them for inspiration. It was certainly a well equipped and well stocked nursery. Any basic comforts one would expect from a normal nursery could easily find an adult sized version of it here. Besides the cribs and changing table, the nursery also came well stocked with a bookshelf of colorful bedtime story spines, piles of plush animals, and an open chest full of fun looking toys.

“S-stay right there!” Fluttershy chirped as she carefully crawled off of the red stallion.

Digging into the mess of toys, Fluttershy came back with wingfuls of brightly colored hunks of plastic and huggable stuffed animals. There was no method to her selection. Instead she grabbed whatever she could to pile around the stallion. She wanted it to look like the big stallion was in the midst of playtime, too distracted to even pay attention to his diaper which had become deeply stained with browns and yellows. She giggled to herself at the scene she played in her head. It all started to come together as she handed off a large, pink teddy bear to the diapered stallion.

“And and put this plushie between your legs l-like you’re trying to grind against it!” Fluttershy stifled a giggle as she surrounded the stallion with the nursery’s toys. Mcintosh blushed, but climbed on top of the big teddy bear all the same. He now resembled a mischievous little colt, getting into trouble with his mess of toys. The teddy bear, just about as big as Mcintosh himself, seemed to fit nicely between his legs with it's cute buttoned face pressed firmly against his stinky diaper. “N-now don’t you move from that spot,” Fluttershy gulped, “I-I’m gonna uhm...get Mrs. Cake to change your...stinky pants.”

And with that, Fluttershy trotted out of the room, closing the door behind her.
