The Best Part of Waking Up

The navy blue unicorn stallion Cobalt Blaze was awakened by the gentle, loving nuzzles of his husband. In the mind of the dark brown pegasus stallion Sky Scribbles, his husband wasn't greeting the morning nearly fast enough, so he reached forward with his right wing and tickled him behind the ear, then slid down and did the same with his left wing and fiddled with his side just in front of his cutie mark, one of the very few spots where he was ticklish. The gesture succeeded in getting a tired moan of protest out of the unicorn, who could never be called a morning pony.

"Com'on, Cobalt. Celestia raised the sun a half hour ago..." The pegasus whined, fluttering his wings as he began to trot in place. Groaning in protest one more time, Cobalt rolled over off the bed and set his hooves on the floor.

"Okay, okay," Cobalt replied with a yawn and a stretch. He couldn't exactly blame his husband for his eagerness; they only got to do this around once a week, depending on if their days off lined up, and he was just as eager when it was his week. Luckily, this time, it was both their turns. It was going to be one of their 'hybrid' days.

Cobalt's horn glowed as magic began to flow through it, and Sky felt himself go weightless as he was picked up with the unicorn's magic and carried over to the north side of the room, decorated considerably differently than the south side, which was set up like any normal bedroom could be expected to look like; full size bed, dresser, night stand, lamp, and alarm clock. The other side however, was a completely different story. A crib sat adjacent to the bed on the other side, with a large dog's bed on the floor in front of it, with a food bowl next to it. Inside the dog bed rested a blue collar and leash. Next to the crib was a diaper changing table, but far larger than would be necessary for a foal, and a six-tier shelf next to that, stacked with dozens upon dozens of disposable diapers in various patterns, and other supplies that were associated with the aforementioned task, such as foal powder and scented wipes.

It was their play space.

Sky's wings again fluttered in excitement as he found himself gently placed on his back on the cool plastic-backed cushion of the changing table, and a single safety strap was fastened across his midsection. With another yawn, Cobalt ruffled his husband's mane.

"Alright, wait here and I'll be back." The unicorn told the pegasus who was now looking up at him from the changing table.

With another yawn, Cobalt left his husband strapped on the changing table while he went down the hall to the kitchen. He had a couple of things to do here, the first of which was wake himself up with a quick breakfast. Sky had baked a dozen muffins the night before, which were in a plastic container on the counter. As he took one in his magic and poured a glass of orange juice, he also went to the cupboards and took out a glass foal bottle, again far larger than you would give an actual foal, complete with a rubber nipple that was meant for a full grown pony. He twisted off the lid, and filled the bottle with milk, before putting the lid back on and set it in a pot over a low burner to warm it up. By the time he had finished his muffin and juice, the contents of the bottle on the stovetop had been warmed sufficiently. Taking the bottle in his magical grasp and shutting off the burner, Cobalt returned down the hall and came back into the room, where Sky was beginning to squirm, barely able to contain his excitement. He came up to the pegasus laying on the changing table, smiled down at him lovingly, and offered him the bottle of warm milk, which he immediately accepted and began to nurse from the nipple, as Cobalt began his work.

With the bottle resting in the pegasus' front hooves, Cobalt released his magical grasp and took it over to the shelves, where he grabbed a bottle of foal powder and a thick, poofy disposable diaper, and began to unfold it as he floated it over to the prone nursing pegasus. He used magic to lift Sky's flanks off of the mat, and expertly slid the split back end around his blue and purple tail before taping the tail hole shut, and set the pegasus' rear on the soft inside of the garment. He twisted open the bottle of foal powder, admittedly Cobalt's favorite part of his husband's kink, and he began to sprinkle his nether regions with it. That task complete, Cobalt twisted the cap closed, set it aside, then began to gently rub the foal powder into Sky's balls and growing stallionhood with his hooves. Then, he brought the front of the diaper up between his rear legs, making sure the front was positioned far enough up that it would cover the pegasus' erection, then smoothed it across his stomach, tucked the wings under his sides, then brought the rear wings up, and fastened it snugly with the four strong tapes.

The diapering of his 'foal' complete, Cobalt lifted the pegasus off of the changing table and floated him towards the adult-sized crib as he lowered the bars to set him inside, as he passed the halfway point of his bottle of warm milk. The side of the crib opened, Sky was set down on the crib's mattress, the crinkling of his fresh diaper joined by the crinkling of the fitted plastic sheet underneath the fabric sheets. Using his magic to fluff the pillow before Sky's head came to rest on it. Seeing he was approaching the one-quarter mark of milk left in his bottle, Cobalt made sure he was situated in his crib, then began to climb in on top of him.

"While I don't think for a moment that you need any help in not staying dry while I'm gone, I know you love being my own adorable little toilet." Cobalt told his diapered husband, who didn't reply through the nipple of his bottle as the unicorn began to lower himself down onto his midsection, facing towards his rear legs. Sky felt the front of his diaper magically tugged up, and felt Cobalt's semi-hard stallionhood slide in next to his own.

Cobalt made a couple of small adjustments, and then answered his body's morning call of nature as a stream began to flow into his husband's fresh diaper. Sky's cheeks tinted pink as he felt the heat of the unicorn's urine pour over his nether regions, trickling down between his legs as his diaper began to drink it all up. Indeed, this had become one of his favorite parts, and Cobalt was now as accustomed to using Sky's diaper as Sky was himself.

So the day of their role play had begun, and Sky's diaper had been clean and dry for barely half a minute. In the thirty seconds that it took Cobalt to empty himself into his husband's diaper, the pegasus had finished his bottle, the nipple giving off a wheeze of completion as Cobalt tugged himself out of the waistband, keeping the now semi-swollen garment snug around Sky's flanks. Seeing that he had finished his bottle, Cobalt magically took a hold of it, set it on the edge of the changing table, before turning his magic on the pegasus, bringing his front hooves back over his head and magically restraining them near the top corners of the crib.

"Can't have you getting into trouble while I run my morning errands." Cobalt said as he got up off of his husband, making sure the spell holding his front hooves in place was stable.

"Be good now, and I'll be back soon." Cobalt told him, kissing him on the forehead and placing a pacifier into his mouth. He raised and locked the bars of the crib, turned towards the door, grabbing the bottle on his way out, and gave the pegasus a loving smile before shutting the door, leaving him alone in the crib.

Foaling Around

Sky let his head sink into the soft pillow as he slowly exhaled, his breath exiting around the pacifier he held between his teeth, taking in the euphoria of his current situation. He laid on his back in his crib, front hooves magically restrained towards the top corners of the mattress, and his diaper had been positively dampened by his husband's morning relief, the stench of which was beginning to reach his nostrils, and kept him semi-hard beneath the warm, swollen padding around his nethers.

'Wonder how long he'll be gone this time.' The pegasus thought to himself, fairly certain that around ten minutes had passed since Cobalt's departure. The bedroom's sole clock wasn't visible from the crib, and this was done on purpose, as the crib also served as his timeout space, and it was none of his business how much time had passed. Sometimes Cobalt was only gone for a half-hour, sometimes he was out in town until nearly noon; when he was restrained in the crib, he was never told, and that was part of the fun; role play was always more interesting with the occasional mind game.

Any newbie to bondage might be a bit worried about being restrained for an unspecified time alone, but the couple had worked this out; safety was always their top priority no matter whose day it was to play. The magical restraints that kept his front hooves in place allowed for a few inches of movement in any direction, and could also allow their places to be alternated, allowing Sky to roll over onto his stomach should he need to. If he absolutely had to get out of the crib, the unicorn had taught Sky a spell-breaking incantation, exponentia ruptor, that would immediately dissipate the restraints upon the words being spoken in proximity to them. To guard against the pegasus forgetting the words in a panic, Cobalt had expertly engraved them into the top rail of his crib, where they could easily be seen.

The restraints kept him mostly in place, true, but mostly it was to keep the mischievous pegasus' hooves away from his diaper. If he was really set on getting off, he could simply roll over and grind against the mattress, but not only would that end today's fun all too early, doing so without Cobalt's permission would also get him a blistering spanking, especially on a non-hybrid play day. For now, he was content on behaving, occasionally and softly squeezing his legs together to feel the squishy bulk between them.

But it wasn't too long before his bladder too signaled that enough was enough; the night was over, it was time to empty. Not only that, but the Super Ultra Extreme Awesomemazing Nachos Supreme from dinner last night had also completed the course through his digestive tract as the pressure in his bowels began to increase, and it wasn't going to wait for him to find a bathroom; he had been role playing with diapers for all of his adult life, and his brain had figured out long ago that the crinkling garment around his waist was an acceptable place to relieve oneself.

Not wanting to leak, his semi-hard stallionhood increasing the risk of such if he were to let go while laying on his back, he pulled at the magical restraints, using the spell's firm resistance to pull himself up into a half sitting position, took a breath, and let it out, along with the urine in his bladder. His 'Foal At Heart' diaper swelled even more as it accepted Sky's wetting along to join Cobalt's. When the stream died down, he let out a few more weak squirts, gave it a few seconds to fully absorb, then slid back down to his laying on his back, sinking back into the pillow once more.

This was bliss.

Sky wasn't sure what he had done to deserve Cobalt, but the pyrotechnic unicorn was everything to him. They had been happily married for just about half a year, and engaged for three years before that. Even before that, when they were dating, when he sensed that they were really starting to connect, Sky dared to tell him about this side of himself, and Cobalt accepted everything he had said without a second thought.

"You don't pick and choose parts of somepony to love and accept, you take all of it." He reassured his coltfriend at the time.

It was these words that were cemented in Sky's heart, and truly made him believe that Cobalt was the one for him. To be fair, it was much more than their kinks and fetishes; they loved cooking together, going for hikes, and shared almost all of their hobbies. The unicorn wasn't without his kinks or quirks, either. Soon enough, he had opened up about his micro sizeplay and submissive pet side. Sky had been so eager to show him his acceptance that he had quickly gone out and bought a blue collar and leash, complete with an engraved, heart-shaped nametag with his name on it.

It might as well have been an engagement ring. For both of them, having a partner to role play with was one of the best things about life right now. Of course, with Sky's two part time jobs of weather pony and columnist for Ponyville Daily, and Cobalt's as a pyrotechnician and wagon repair, the pair usually only got to set aside a day or so a week, so they went on a set schedule; ageplay for Sky one week, pet play and sizeplay for Cobalt the next, then to mix things up a bit, they incorporated elements of both for the third week, what they coined 'hybrid' days.

Their mindsets changed from time to time, too. Sky, ever the adult foal, got it in his head one time to ask Cobalt to wet his diaper for him, and the unicorn obliged, and the act quickly became part of the pegasus' mindset. Cobalt, happily playing the part of a loving foalsitter, had to be gradually coaxed into adopting a considerably more disciplinarian angle with Sky when he decided to be a brat. He initially shied away from making the pegasus' flanks burn red, but Sky reiterated that that was the point. Now, it had gotten to the point where Sky had to think twice whenever he set out to deliberately misbehave for his dearest, because while the unicorn had a healing spell ready for bruised and burning flanks, he was no longer above delaying the application, letting the pegasus think about what he had done.

Cobalt was no different; he also had quirks about his 'pet' mindset that he had to ease Sky into. There were days that the unicorn wanted to be nothing more than an adorable, loving lap pony. Then there were times where he wanted Sky to pin him to the floor, put him in his place, and pick an end to shove his throbbing stallionhood into, and often wanted his husband to get physically restraining in the process. It started out awkward at first, but as the two switches got more comfortable with each of their submissive and dominating sides, they wouldn't have it any other way.

After a few more minutes of pacifier suckling and light leg wiggling, his bladder empty, now it was his bowels' turn for some attention. The pressure continuing to build, Sky gazed back at his restrained hooves, and rolled over onto his stomach, the glowing points of light that held his hooves allowing his limbs to switch places. Then he raised his back half up, and allowed nature to take it's course. His tail hitched up, and he began to push. His poop began to come out, and soon met the resistance of the diaper, and it began to spread. The sensation never got old to him. It was warm; almost too warm at first. It was the ultimate expression of foaling out, the biggest sign that he was helpless and needed someone to look after him.

Thirty seconds later, the deed was done, and he slumped down onto his stomach, the fresh, warm mess in the seat of his diaper pressing up against his balls. It was almost enough to make him drool. Feeling how full his diaper now was caused his erection to come to full attention, and Sky knew that he wouldn't have the discipline to resist humping against his mattress if he didn't roll back over. So he did, resting his head back on the pillow as the stench of his now stinky diaper wafting up to his nose.

He hoped Cobalt wouldn't be too long with his morning errands. After all, this was his day too.

Author's Note

Hope you're all enjoying this story, even if these chapters are a bit short. Regardless, thanks for reading!

Also, a special thanks to the downvoters; who continue to reaffirm what I've always believed about their kind.

A Change

Cobalt Blaze was closing in on downtown Ponyville as the morning sun continued its journey upward. Far from the only one, he greeted and waved to the various other patrons making their way through the marketplace on their morning errands. While he was confident he could do this quick trip out in twenty minutes, he didn't think there'd be anything wrong with grabbing a quick bite to eat to supplement the muffin he had. It wouldn't be much fun to make it too easy on Sky now, would it?

So after stopping at the Sweet Apple Acres cart, run by Big Macintosh on this particular morning, he now had an apple tart to munch on as he continued past the kiosks and towards the interior businesses. The particular one the unicorn was looking for this morning was Silly Filly, a foal care supply store near the center of town. The signage above the door was rainbow colored and playfully shaped. Upon walking in the front double doors, a bell chimed above, signalling his arrival into the store. There were a few other shoppers there, mostly with carts with babbling foals seated in them while their parent got what they needed.

Cobalt, however, went right for the service counter in the back, where a light purple earth pony mare was standing.

"Good morning, Cobalt. The usual restock, I'm assuming?" Cashier and co-owner Soothing Care asked him as he stepped up to the register. Cobalt nodded with a smile. The couple Gentle Care and Soothing Care ran Silly Filly, the best foal care supply store in town. To most of the Ponyville polulace, it was the place to go if a couple was expecting a newborn or two... Or three.

To considerably fewer, the ageplayers of the region, this was the place to go if you wanted the appropriately and proportionately sized items needed to return to some semblance of your foalhood, and you had some bits to spare. The shop did absolutely no advertising of that side of their business, which was kept entirely in the back storage area. On the contrary, if either of the entrepreneurs saw a pony lingering in an aisle, mainly the diapers, for an extended period of time, they would professionally approach and ask if the size they needed was on the shelves, or if they needed something bigger. Sometimes they left embarrassed only to come back at a later date with more confidence, or they sometimes asked how big they went, which they replied with an extremely nervous 'adult.' Pretty soon, news spread via word of mouth, and the Cares' ageplayer side of the buisness was just as busy as the foal side. They had visitors from as far out as Manehattan and Fillydelphia, and if they couldn't make it to the store physically, the couple happily sent out orders for a modest shipping fee.

After ringing up Cobalt's restock order, Soothing Care quickly went back to the storage area and was back in two minutes with a plain cardboard box, with no markings whatsoever to give away the contents that wait within; three dozen Foal at Heart diapers, two containers of wipes, and two bottles of foal powder. Cobalt slid two silver 50-bit coins, took the box in his horn's magical grasp, thanked Soothing, and was on his way without a fuss.

Levitating the box just above his back, it was an eight-minute walk back to the small one-bedroom dwelling he shared with Sky on the edge of Ponyville's west side. Walking in the front door, he carried the box back towards the room, and wasn't even through the bedroom doorway before his nose picked up the unmistakable scent of a dirty diaper. He scrunched his nose and made his way into the bedroom, where he saw Sky still in the crib, head rolled far to the right, his tongue trying to pull his pacifier back into his mouth.

"Hey there you." Cobalt greeted, setting the box next to the changing table, and came up and lowered the rails of the crib. He magically grabbed the wayward pacifier and popped it back into the pegasus' mouth, before his gaze fell down to his husband's diaper. He pressed lightly on the front, then gently slid down to between his legs, and pressed, getting a soft, mushy resistance in return, as well as a fresh waft of manure.

"Tsk tsk. I think I have a stinky little colt here, don't I? Sheesh, I wasn't even gone an hour. What a helpless little baby." Cobalt told him, Sky's cheeks reddening at the words. He could never get enough of Cobalt's chastisements. He felt the magical restraints dissipate and his body levitated up out of the crib and floated over to the changing table. His diaper sagged slightly, but was once again pressed against his body when he was set down on the cool changing mat on the table.

To Cobalt, dealing with Sky when he peed in his diapers was no big deal, but messy diapers were decidedly his least favorite part of his husband's role play. But he stomached it, because he knew that the act, and being cared for and cleaned afterward, got Sky further into his headspace than any other ageplay activity.

The unicorn took one last breath of comparatively fresh air, then ripped the tapes of Sky's well-used diaper one by one, before opening it up to start to deal with what wait inside.

"Oh my, what a messy, horny foal I have here." Cobalt said, taking note of the hard erection that had thankfully stayed relatively free of the mess in the back of the diaper. So he had been a good colt and didn't get off without permission. The words succeeded in getting Sky to hide the bottom half of his face behind his front hooves in embarrassment. He began cleaning off Sky's rump as best he could with wipes in his magical grasp one by one, before he lifted Sky off the dirty diaper and rolled it up and deposited it in the pail under the changing table. Keeping his back half suspended above the changing mat, Cobalt finished cleaning his husband's posterior, before giving his front side a good once over, focusing especially on his stallionhood, before unfolding a clean diaper and slipping it underneath before setting Sky down on it.

Instead of feeling and smelling foal powder being sprinkled on him, he instead felt the cold, wet substance around and in his tailhole, and peeked down and indeed saw a bottle of lube in Cobalt's magical grasp. Thus, it was time for what the couple had deemed a fair trade; Cobalt's price for cleaning his messy butt; putting it to use immediately after.

'Poop comes out, dick goes in.' Cobalt had lewdly joked awhile back.

With Sky's tailhole sufficiently lubed, Cobalt turned his attention to his own erect stallionhood with another magically-levitated glob of lubrication. A few seconds later, the unicorn raised up, putting his front hooves up on the changing table on both sides of Sky, his slick cock beginning to gently prod the pegasus' hole. Sky lowered his front hooves to the changing mat, preparing himself for the entrance. He had been on the receiving end far less often and for far less time than Cobalt had been, and he had discovered that the key to enduring the initial entrance was to not forget to breathe.

'Just concentrate on your breathing, Sky.' The pegasus told himself. And so he did, doing his best to relax as Cobalt's unflared head began to slowly press into him, centimeter by centimeter. At the halfway point, Cobalt paused, letting his husband get used to him, going gently back and forth a few times, before continuing in further. When the unicorn had bottomed out, Sky could swear he felt Cobalt's tip in his stomach. The unicorn slowly pulled out halfway, then slid back in just slightly faster. He repeated this a few times, getting a bit faster each time. As much as Sky tried to keep his breathing steady, his breaths were seemingly pushed out of his lungs every time Cobalt bottomed out his cock inside him.

"Good boy... Good boy..." Cobalt praised his foal, encouraging him to keep his breathing going, as it never took him long once he sunk himself inside his husband; he was just too fucking adorable, how he moaned and whined in between breaths, how his erect wings fluttered with nearly every thrust. His own stallionhood was throbbing and rock hard, but it wasn't quite enough to get him off; in his mind, getting fucked didn't quite compare to the touch of Cobalt's hooves, or the soft, thick embrace of a diaper, be it clean, soaked, or messy.

Cobalt's increasing rhythm began to get a bit jerky and Sky knew it would only be a few more seconds. The unicorn's breath deepened and he gritted his teeth as he suddenly halted his thrusts, sinking all the way into his husband, and his tip erupted with a flow of hot spunk, pumping it into his pegasus' backside. One load, followed by a second, third, and fourth.

After ten seconds, they decreased to weak squirts for another five seconds, then down to a dribble, and then Cobalt had emptied himself entirely into him. By now, he was panting lightly, gazing down lovingly at his dearest.

"What a good little pony you are..." Cobalt praised as he began to calm his panting, leaning further down to kiss him on the snout. He began to slowly pull out, and as soon as he was free with a squelching sound, Sky immediately felt something else poke at him, considerably colder than Cobalt's length had been. It took him only a second to realize that Cobalt had lubed up their butt plug.

"Since you've already emptied yourself out already, how about you keep that in you for a little while, hm?" Cobalt said as he gently nudged and twisted the plug into his husband. Once the flare was in, it slid in the rest of the way easily, and was held in place by the flat base. Giving it a few loving pokes to make sure it was snug and secure, Cobalt then followed through with sprinkling the foal powder over Sky's diaper area, then brought the front of the diaper up and taped it snugly shut. He patted the front of the diaper, Sky's erection easily identifiable even through the thick padding, and levitated him up and set him down on the floor.

Sky fluttered up to the top shelf, grabbed a blue collar off with his teeth, and took it on the tip of his left wing upon landing back on the carpet, spinning the collar with his wing.

"Now don't think this cute little foal of yours has forgotten that this is your day to play too..."

Pet Play

Similar to how Sky's stance and expression changed upon being laid on the changing table and diapered, something similar happened to Cobalt as Sky came forward with his blue collar, and fastened it around his neck. On the front was a purple heart-shaped name tag, engraved with 'COBALT'. When he was done making sure it was snug, but not too tight, Sky stepped back and noticed how Cobalt's ears drooped just a bit as he too began to slip into his submissive mindset.

"Now, stay here and be a good boy while I get lunch ready." Sky said, ruffling his husband's mane, which caused his ears to perk up as the pegasus picked up his food dish in his right wing and went down the hall to the kitchen, his clean diaper crinkling with each step. He trotted into the kitchen and set the food dish on the counter while he went for the plastic container that had sat next to the stove since last night. Inside were a half dozen muffins. He opened the lid, took out two, removed the wrappers, and crumbled them into the bowl. Next, he grabbed a bottle of maple syrup from the pantry, and dribbled a half cup of it onto the crumbled muffins. After giving it a quick mix with a wooden spoon, Sky looked at the final product sitting in the bowl and saw that resembled fresh, wet dog food. Satisfied, he poured himself a sippy cup of apple juice before picking up the bowl with his other wing and returned to the bedroom, where his husband was currently softly chewing on a squeak toy.

"Alright, enough of that, time for lunch." Sky announced, flicking the small rubber hoofball away and set the bowl down in front of Cobalt, who gave the contents a test sniff, getting a chuckle out of Sky. He could never be too careful. But after getting a whiff of the maple syrup, Cobalt was confident that Sky wasn't trying to pull a fast one and serve him actual pet food. He took a bite and immediately knew they were Sky's muffins that he baked last night, mixed with a bit of maple syrup. While he eagerly began to devour his breakfast, Sky was content to sit across from him and sip at his cup of apple juice.

They finished at nearly the same time, and as the pegasus stood up and ruffled Cobalt's mane as he petted him, he felt a magical tug on his diaper as the unicorn performed a simple diaper check. He could never be too careful. With that, the duo took their bowl and cup to the kitchen, gave them a quick wash, and set them on the rack to dry.

"Now I bet you can't wait to get to your favorite part." Sky told his husband as they walked back to the room together.

"Mmmmaybe..." Cobalt replied, his horn lighting up, and on top of the shelf, tucked away safely in the back corner, were a pair of rolled up scrolls. He brought them down to eye level, and unfurled them. His horn fired off a magical beam at the one on the left, and it in turn began to glow and the beam continued on towards Sky, who glowed momentarily, and then returned to normal, except for one detail. He turned his head and looked to confirm that his diaper was now invisible.

Satisfied, Cobalt fired another beam of magic at the second scroll, and this one reflected it right back at him. There was a flash of light and puff of smoke, and when it cleared, Sky glanced down to the carpet.

For there was his husband, two-and-a-half inches tall.

"There we go," Sky began, bending down to address his dearest as close to eye level as he could manage.

"Perfect for a walk outside."
