Winter's Morning

Sandbar slowly returned to the waking world, a fuzzy warmth surrounding his whole body. With a stretch, he remembered the new fleece hoofed pajamas he had gotten last night for Hearth's Warming Eve. They had fit perfectly, and made his fresh diaper all the more snug against his body when he had climbed in to his crib for the night. Now that it was morning, his cool, wet diaper was considerably swollen, and could be seen as a bulge through the pajamas.

"Morning, cutie. Let's get you out of there." Came the voice of Gallus. The sound of the bars being lowered had long become routine to the pony. He groggily rolled over and his hooves hit the floor as he nearly fell out of the crib. His diaper, which would normally be sagging in warmer weather, was held in place by his new pajamas, dark blue and pattered with air bubbles, looking like the depths of the ocean.

Gallus came up beside him and gave his rump a few test pokes and squeezes, getting wet squishes in return. Morning diaper checks were practically meaningless; when Sandbar wore to bed, he almost always woke up wet, having been completely diaper trained for a couple months now. It's not that he went in his sleep, but half waking up through the night to empty his bladder was now second nature.

"Yep, you're soaked. Come on, let's get you changed." Gallus told him, beginning to guide his foalish boyfriend over to the changing table. As he was still half asleep, it didn't take much to push the yawning pony down to the left end of the room. All too used to this routine by now, he slowly climbed the steps, and gently flopped down on the padded changing table, laying on his back, and started to hear Gallus go to work; the first sound was the zipper of his new pajamas. They were tugged off without much effort, and now the slight chill in the room became apparent. now with his big foal in nothing but his diaper, the second sound was the tapes ripping. As the now-sagging sea-life-patterned disposable undergarment was peeled away, the last of Sandbar's sleepiness faded away as he felt the cold wet wipes on his stallionhood. Wipe after wipe was deposited in a small pile on the open diaper as the night's worth of urine was cleaned off. The attention he was receiving down there also usually got him semi-erect, which was all too easy in the morning.

The cleaning part done, Gallus briefly lifted Sandbar's flank off of the table and pulled the wet diaper out from under him, rolling it up and pushing in into the diaper pail next to the small staircase. Usually, this was where the role play ended, and he'd take a quick shower before getting ready for the day. But today was different, as Gallus pulled a fresh diaper and stuffer from the stacks on the shelf. Today was Hearth's Warming, and the role play would continue throughout today. Today was special.

"So are you sure about this? Probably the last chance to back out." Gallus said as he opened the clean diaper and laid the stuffer inside, adhesive side down, effectively increasing the capacity of the garment, and nearly doubling the length.

"Well, I am a little nervous. But no, I've made up my mind. They've been wondering long enough, and it's not nearly as easy for them to eavesdrop now that we've moved out of the dorms." Sandbar replied as his back legs were once again lifted and the fresh diaper was placed underneath him and fastened around his tail, before he was lowered back down onto it.

"I can't imagine you being as nervous as you were when you stepped out into the living room wearing for the first time in front of your mom and dad." Gallus commented as he grabbed the bottle of foal powder. "Besides, do you really think they'll be that surprised? Pretty much all of them saw how hard you were looking at Starlight's demonstration."

Sandbar figured that was true. Counselor Trixie's 'Kinks and Fetishes 101' summer class had run twice a week for six weeks, and Starlight had been the on-stage demonstration for Week Three. On the day of the last class, Trixie encouraged everycreature to continue exploring and experimenting safely and responsibly. In that time, Sandbar had embraced his previously undiscovered ageplayer side, with the support of Gallus and his mildly surprised parents, and the griffon had also moved in with him. But, suffice to say, they were missed considerably in the dorms. Both of them had entered into a polyamorous relationship with Ocellus last spring, and now they weren't able to get together quite as often. Sandbar figured if he opened this side of himself to his friends, then he could get over the last of his embarrassment, and they could invite Ocellus over here more often. His mom and dad were a bit more apprehensive about the duo's relationship with the changeling, but became more agreeable when they explained how love, both emotional and physical, was a very important aspect of changeling culture.

Truly, Sandbar had never been more appreciative of his parents' open-mindedness than he had in the past six months. Every time he stepped outside his bedroom in this infantile attire, they both regarded him as nothing more than a big foal. Even his three year-old sister Coral Currents who was currently potty training, was now calling him 'Big Baby Brother'.

Gallus sprinkled liberal amounts of powder over Sandbar's diaper area, then twisted the cap shut, set it aside, and brought the diaper up between his legs, smoothed it against his stomach, and brought the back wings up, and tape it up snugly and securely.

"There we go, all clean and dry." Gallus announced, taking hold of Sandbar's front hooves and pulling him up to a sitting position. The pony leaned forward and gave him a kiss on the beak.

"Thanks, big bro." Sandbar said happily, now wide awake. His stomach grumbled with hunger, and the duo opened up the bedroom door, and headed out to the kitchen for breakfast.

Ocellus stood in her dorm room in the School of Friendship, freshly showered and ready to head down to the cafeteria for breakfast. But her mind was still pestered that she hadn't figured out a good Hearth's Warming gift for Sandbar and Gallus. The four of them had exchanged gifts last night after dinner, but Sandbar and Gallus had been away with his family at home.

She glanced over at her nightstand, where an alarm clock and single picture frame stood. The picture within was Gallus, Sandbar, and herself laying in bed together, exhausted, but all three of them still managed smiles. Silverstream had taken that picture as a joke after one of their threesomes where they had happily performed for their other three friends. Ocellus had privately asked her for the instant-developed photo afterward, which she had then framed herself. The residual love that radiated from the photo was always enough to sate her late night appetite just before bed.

It wasn't that she had grown lonely, those two had always managed to make time for her after they had moved out, but she just couldn't make up her mind on what to get them for Hearth's Warming, and the four of them had been invited to a small gathering at Sandbar's house for lunch and hanging out.

So with only hours to spare, she was clearly running out of time.

Outer Discovery

Coral gave a giggle of delight as she caught the rubber ball and rolled it back towards her big brother. Her big baby brother.

Sandbar, suckling on his turtle shell pacifier and sitting in the playpen that had been set up in the living room, stopped the ball with his hooves and rolled it right back at her, at a slight angle, where she would have to lean to catch it, and catch it she did, while managing to keep her balance.

One of Sandbar's initial worries about bringing his ageplay outside of his bedroom was how his little sister might have potentially perceived it. But his mom and dad had reasoned that, as long as he didn't do it all the time, that she would probably just assume it was a game he played, where he became like her for a little bit. It was a fair theory, but probably only one that would hold until she started potty training, which they didn't think was far away, as she was getting fussy more often when she used her diaper. Sandbar didn't indulge in his role play every second at home, or even every day. So far, for the past five months, it had largely varied between every other day, or just the weekends if he wanted more than a 24 hour period padded.

After the ball was rolled back to him, Sandbar mixed it up by bouncing it softly on the wooden floor; not so high that it would clear the walls of the pen, but Coral did have to jump to catch it, and the momentum transferred from the catch caused her to land in a sitting position and roll back, giggling the whole way. Before the filly could toss it back, the attention of both padded ponies was grabbed by a knock at the front door, and Sandbar's gaze went from the foyer to the clock on the wall, confirming that was was quarter to noon. The moment he had been half-dreading had arrived. It was an odd group of butterflies in his stomach, seeing as how this was his idea. He could have very well invited his friends to a perfectly normal Hearth's Warming lunch. In fact, that is precisely what he had done, then when he decided he wanted to show them this side of himself, it was Gallus who had told them to expect something of a surprise when they had gotten there.

Responding to the knock on the door, Gallus came out from the kitchen where he was helping Beachcomber with lunch. He opened the door and greeted their four classmates and best friends.

"Hey y'all. Come on in." The griffon said with a smile.

Smolder, Ocellus, Silverstream, and Yona entered the dwelling one by one, in that order, and also in that order, they saw Sandbar in the playpen, but didn't seem to show any shocked expressions. He realized that it was probably because the fencing of the playpen obscured his attire at this distance, and they had probably just assumed that he was playing with his sister. But the details became clearer as they started filing into the den to greet their other friend.

"Hey there Sandbar, Happy... Hearth's Warming..." Smolder greeted, the first to see the stallion's pacifier, and her eyes immediately fell to his diaper as he blushed at the cheeks.

"Well, no hiding it anymore. Here's the surprise I hinted at." Gallus said, the last to approach the playpen.

Sandbar felt time slow as he took in the stares from his four friends who were being introduced to this side of himself. Smolder and Yona weren't quite sure what to make of it, Ocellus looked more curious than anything, and Silverstream...

Silverstream's surprised expression quickly shifted to overly enthusiastic.

"Oh my gosh, you are soooo cute!" The hippogriff exclaimed, effortlessly hopping over the playpen gate and nearly tackled Sandbar in a hug, which he returned as he struggled to breathe.

"Yona confused. Sandbar like acting like foal?" The yak asked.

"Don't you remember Headmare Starlight's demonstration last summer? Guess Sandbar here liked it more than we thought." Smolder replied, with the pony silently nodding affirmatively, as Silverstream took a seat next to him and began to play ball with Coral.

"So that's why you moved in with them?" Ocellus asked.

"Well, Sandbar here was pretty afraid of showing this side of himself to his mom and dad. So when he ran off to Canterlot Aquarium, I approached them as cordially as I could, and together over the weekend, we turned half of his room into a nursery for him, and they offered to let me move in too. He's been embracing this side of himself ever since." Gallus explained.

"Whatever make Sandbar happy." Yona declared.

"Yup," Smolder agreed. "Each to their own."

Sandbar's lips curled up into a smile on both sides of his pacifier as his friends immediately accepted this side of him. He began to wonder what he had been so worried about; they had sat next to each other for more than half the summer exploring and experimenting with different kinks and discovered what fueled their developing sex drives.

"Alright everycreature. Lunch is ready, come and get it!"

Silverstream picked up Coral and carried her to the kitchen, while Yona had no trouble tossing Sandbar up on her back and gave him a yak ride to his high chair at the table, where a few extensions were put in to fit eight at the table.

"So how come you're showing us this side of yourself, Sandbar?" Smolder asked as she bit into a clawful of nachos supreme.

"Well, as much as I've fallen in love with this side of myself, being able to 'foal out' at home, Gallus and I have certainly noticed how it's taken a considerable chunk of my free time with my friends. I figured if all of you knew about it, we could get some of that time back." Sandbar answered, having taken his pacifier out to eat lunch, which Silverstream and Gallus were currently taking turns feeding him.

"Well, it's great that you showed us how adorable it is!" Silverstream replied happily. "Since, you know, Trixie's demonstration with Starlight didn't really cover a lot of the 'foaling out' parts."

Silverstream was certainly right on that count; Trixie's class that day contained only one piece of ageplay furniture, a crib, and the rest of it leaned heavily towards bondage and exhibitionism. But if this was another chunk of what an ageplay headspace could contain, they could certainly see what made it so endearing.

The visit wasn't meant to be much more than lunch, because some of them had planned to go help with getting last minute things ready at the castle for the Hearth's Warming dinner and Lieutenant Colonel Fizzlepop's fireworks display tonight. So with some quick hugs, Smolder, Yona, and Silverstream said their goodbyes and set off for the castle, while Sandbar and Coral were returned to the playpen while dishes were cleaned from lunch.

Her curiosity having finally gotten too heavy, Ocellus stood in the hallway in front of Sandbar's bedroom door, and peered inside. It was immediately apparent that the room had effectively been split in two; two different styles, two different atmospheres. But both sides had the same energy in common; love radiated off of nearly every surface. The two beds on the right, the cage-bed combination on the left, as well as what looked like a padded table and shelf in one. Even the pet turtles in the terrarium; the love in this room hung in the air so thick that it was almost palpable.

All she knew of equine infancy was what Pinkie and Cadance had covered in their Babysitting Basics class. She didn't quite understand what attracted adult ponies to items and surroundings of their past, but Trixie did point out on several occasions in her summer elective, that when it came to various kinks and fetishes, sometimes you either understood it or you didn't. And she definitely remembered Sandbar's reaction when he first laid eyes on Headmare Starlight up on stage in that crib. She approached the changing table stocked top to bottom with disposable diapers, and gave them a soft poke with her front hoof, getting a soft crinkle in return. She remembered how Trixie had said that some ageplayers liked them as thick and crinkly as possible. As she pulled one out and held it in her hooves, she began to get an idea. She glanced over at Sandbar's desk next to the terrarium and quickly spotted a quill and ink next to a few sheets of paper. She returned the folded diaper to the stack, and went over to the desk, picking up the quill, dipped the tip in the inkwell, and put it to the top piece of parchment...

"Alright, Coral, I think it's time for a change." High Tide said, coming in to pick up the three year-old and lifted her up out of the playpen, taking her upstairs to her room.

"I think the same can be said for you, lil' bro." Gallus said, noticing how swollen Sandbar's diaper had gotten. There would be no picking him up, though, and the griffon merely opened the gate for the pony to step through, and they began to walk out of the den and down the hall towards his room. After they entered the room, the griffon and pony made their way over to the changing table, and they immediately noticed the new items.

There, on top of the padded surface, was an arctic blue disposable diaper with a red bow on it, with a gift tag that read 'From: Ocellus, To: Sandbar and Gallus'.

As the diaper's color matched Ocellus' carapace exactly, with smiling expressions of her face patterned over it, it didn't take them long to deduce where the changeling had gone.

"Well, I guess that's what she'd look like if she was a cartoon." Sandbar quipped, grinning as Gallus rolled his eyes as he picked up the letter and read aloud.

"Dear Sandbar and Gallus,

I've really been struggling lately to come up with a gift that properly expresses how much I treasure the way our relationship has evolved this past year. After I saw this room, I had an idea. Yes, the diaper is me. I can't talk or do anything a normal one wouldn't do. Just put it on the way you usually would, and I can experience first-hoof the how's, what's, and why's of your love of ageplay. Don't worry, if anything goes wrong, changing back won't be any trouble at all.

Love,
Ocellus."

Gallus set the letter down on the nightstand and picked the unquestionably living garment.

"Well, little bro, what are you waiting for? Hop on up."

Ocellus Gets 'The Talk'

School of Friendship, Graduation Day
Last Summer...

"Well, Ocellus, I have to say I'm very proud of you for completing your first two semesters at the top of your class, and so is the rest of the hive." Thorax congratulated his top international student as they sat in the castle dining room among the rest of the first year students. Stopping magic from being eradicated from this realm did wonders to boost one's grade point average, but the changeling was proud to say that she didn't even need that as help.

"Thanks, Thorax. I'm actually wondering if it'd be alright if I stay here over the summer. There are some summer electives I'd like to take, plus one that I'd need your expressed permission for." Ocellus replied.

"What sort of class?" Thorax asked, taking a bite of his cupcake as Ocellus began to rummage around in her saddlebag, coming up with the permission slip in question. He took it, and read it silently.

"Kinks and Fetishes 101? Why would they be offering an elective like this?" Thorax asked, puzzled.

Ocellus gulped nervously. This was no time to do the Element of Honesty a disservice.

"Actually, it's kind of our fault..." She admitted, looking down at the tablecloth.

"Who's fault?"

"Mine... Gallus'... Sandbar's... We've gotten close."

"How close?"

"Very."

Thorax set the piece of parchment down on the table, looking over at the young changeling, who was trying and failing to hold back a blush.

"Well, I honestly wasn't expecting to have this kind of conversation at your first year graduation celebration, but I do suppose that everyling matures at their own pace." Thorax said.

"Yeah, I... I'm honestly wondering how to go about it safely, because, well... The first time we tried something, we accidentally involved the entire dormitory... And part of the castle."

Thorax's eyes widened in surprise.

"...How?" He asked incredulously, but keeping his voice down.

"Well, when I... You know... I involuntarily released a magical shockwave, carrying everything I had been holding in."

Thorax rubbed his forehead with the tips his hooves.

"They must be lenient indeed if I never got wind of this." Thorax commented.

"Well, for the record, I did get in trouble, but we cleaned everything up; me and the five that were participating... And watching..."

Now Thorax was attempting to fight back a blush, as Ocellus continued.

"But obviously Counselor Trixie wants us to continue to explore and experiment with each other safely. But, you know, going out into the middle of the forest isn't the most convenient when you've only got an hour or so. Plus there's the wildlife to consider. So I guess what I'm asking is... If there's some way to stop that from happening?"

"Ocellus, if your parents found out about this..."

"But you just said everyling matures at their own pace. I can tell you right now that I'm ready. If there's a way to get that close to other creatures without involving anyone unwilling, I'd like to know how. Please."

The changeling ruler gave an exasperated sigh, realizing that Ocellus had talked him into a corner.

"Where's the school dormitory, can you show me?" He asked, finishing off his cupcake.

Ocellus nodded and immediately got to her hooves, leading Thorax out of the dining room and castle, and over to the School of Friendship, taking him through the main hall, out to the courtyard, and into the dorm halls.

"So when did this all start?" Thorax asked as they walked through the various dorm rooms, some doors closed, others open, some in their rooms packing to go home for the summer.

"A few weeks ago. Sandbar asked Gallus out, and they started dating. It was the first time I ever felt that kind of energy, that kind of love." The changeling student explained.

"Well, I was wondering if and when you'd start to encounter energy like that here, and not only sustain yourself on it, but also create it yourself. This is the School of Friendship after all, and sometimes friendships go to the next level." Thorax responded.

Ocellus' room was the last on the right, directly across from Gallus and Sandbar's room. She opened the door, and took Thorax into the single-occupant dormitory.

The room was immaculately kept and organized, with a bed, desk, small closet, and bathroom.

"So you stay in here alone?" Thorax asked, and Ocellus nodded.

"Alright, that's for the best, because you're most likely going to need practice venting."

"Venting?"

"If you want to avoid a magical shockwave like last time, then the most simple way I can put it, is you need to release it in smaller amounts. You have to let it out at the same pace or faster than you feel it building up inside you. Most changelings call it venting. With a little practice, and enough focus and concentration, you can even pass it onto, well, whoever you're having fun with."

Ocellus realized that Thorax probably had a point. Their first night together, she likely wasn't just feeding off of Sandbar and Gallus as they gave her the first rutting, and best time of her life, but Silverstream, Yona, and Smolder as they looked on, too.

"But, then where's the fun in it for me? How will I... You know?" Ocellus asked, twiddling her front hooves to avoid saying the words on her mind.

"Remember, Ocellus, you're a changeling. Love, both emotional and physical, takes on an entirely different meaning for us than it might with other species. You'll feel it build up to levels containable within a room when those you're with also build up, likely achieving sexual release together. Like I said, it takes practice. And I'd highly recommend practicing alone, until you've got the hang of it. Then you can have fun with close friends again without involving the entire student body. But please be careful. Mating season is coming up in the fall, and if you have to come home with fertilized eggs, your parents would never let me hear the end of it, and likely not let you come back."

Ocellus blushed, then smiled up at the changeling ruler.

"Thanks, Thorax. I'll be careful, I promise."

Author's Note

Figured it was time for a little flashback of sorts. Hope you're all enjoying!

When A Changeling Needs A Change, Part 1

As Sandbar climbed up onto his changing table, Gallus removed the bow and gift tag from the diaper, and from how often he had changed his boyfriend, felt it was a bit bigger in his claws. He gently set it to the side, and untaped Sandbar's current, soaked diaper. As he cleaned off his coat with wet wipes, the pony got semi-erect, but the griffon elected to ignore it for now.

With Sandbar as clean as he would get without a bath, Gallus took the arctic blue diaper and began to unfold it, and his suspicions were confirmed. It was as if he had taken one of his regular diapers and put two stuffers in it; it was almost twice as thick. Secondly, as he unfolded it and got it underneath the pony, he noticed that the fasteners weren't adhesive, but rather hook-and-loop velcro. It wasn't Sandbar's first choice, as he thought that the tearing of tapes put him more in his little space, but it would work just as good, if not better; velcro tabs were great if the diaper needed to be readjusted. Quickly concluding that their transformed friend wouldn't need any help in the form of a stuffer, the griffon was about to give him a quick dusting of foal powder, then reconsidered, opting instead for the bottle of oil right next to it on the shelf. He had absolutely no idea what this experience was going to be like for Ocellus, but figured oil would be better in this case, as he dribbled it over Sandbar's diaper area, and rubbed it in, making sure it was applied everywhere, even briefly putting a talon into his plothole, getting a shudder in return. With the process nearly complete, Gallus brought the front of the diaper up, smoothed it against Sandbar's belly, and brought the back wings up and fastened the tabs.

"Wow... Gal... It, she, fits perfectly." The pony commented.

Gallus did indeed notice how Ocellus had done her homework, and turned herself into a garment that seemed to be tailored exactly to the pony's dimensions. His regular stash ran just a hair big, and you wanted that, because it was easier to deal with a little big than it was dealing with a little small.

Sandbar got off of the table and walked around, feeling how Ocellus had wrapped around his flanks flawlessly.

"So... What now?" Sandbar asked.

Gallus glanced out the window, and saw that not only was the sun starting to set, but snowfall was also starting to come down considerably.

"Well, I'd say we've got to bundle you up if we're gonna make it to Captain Fizzlepop's fireworks show at the castle." The griffon told him. The Hearth's Warming snowfall was almost always heavy, but nopony complained, as it set the mood perfectly for the fireworks and the feast afterwards in the castle. The griffon went over to the closet and pulled out some long wool socks, a pair of snow pants, a turtleneck sweater, and a dark blue stocking cap. He was helping Sandbar into the pants when Beachcomber walked in.

"Alright, are you two getting..." The stallion trailed off when he noticed that his son was putting clothes on over his diaper.

"Now Sandbar, you know the rules." He told them.

"It was my idea, Beachcomber," Gallus started, letting Sandbar resume dressing himself as he explained the situation to his father. "I thought me and him could do something special, since nopony is bound to notice under the winter clothing."

Beachcomber glanced over at Sandbar once the thick, insulated pants and sweater were on, and saw that Gallus did have a point.

"Well, alright. As long as you two are careful, and don't involve anyone unwilling. So Gallus, that means if it smells like he needs a change, the fireworks are cut short for you two, and you bring him right back here."

"Understood." Came the griffon's reply.

"Okay, well, we'll be leaving in five minutes."

With that, Beachcomber left to get dressed, and with Sandbar ready, all Gallus needed was a simple red and yellow scarf, his down feathers underneath the exterior feathers kept him plenty warm in colder weather.

"Alright, ready to go, little bro?" Gallus asked. Sandbar answered with a smile and a nod, and they walked out into the hallway together. Gallus noticed that the diaper's crinkling had been sufficiently muffled by the pony' winter clothes, and likely the only reason he picked up on it was because he was actively listening for it. They were both a little disappointed that Ocellus would miss the fireworks; it was one of her favorite experiences when they had all stayed in Ponyville for the holiday last year. But they quickly surmised that she was having quite the unique experience right now...

When it came to taking the form of inanimate objects, the concentration required for changeling magic made normally life-critical functions such as breathing completely unnecessary, at least for a time. It was useful for hiding, but only for a few moments. But if said object was a source of love, changelings could use that to sustain their chosen form for longer, which was exactly what Ocellus was doing at this moment.

She had transformed mere moments before Gallus and Sandbar had returned to the room, and the instant Gallus had unfolded her and set Sandbar's rump down on her form, she instantly felt the love he was excreting. It was a... Complicated love, for sure. It was just as intense as the love he had for Gallus, his parents, his pets, and his friends, but it's origin was very, very deep; so far down in the pony's psyche that even he didn't know where it had come from. She had felt something similar when Starlight had been on stage for Trixie's demonstration last summer. But this was much closer, and much more intimate. After her form had been wrapped up around his flanks, she felt her already snug fit become gently pressed closer to Sandbar's body as he got a sweater and pants on for the fireworks show tonight. Missing those was going to be her single regret for tonight, but she was willing to trade it for this experience.

As they made their way out into the snowfall, Sandbar was having a hard time not being completely enraptured by how his current padding felt under his winter clothing. He wondered if Ocellus was doing her 'venting' technique that she was taught in order to avoid a magical shockwave that had occurred during their first night together. If it was concentrated enough in her default bug-pony form, it came out as a glowing green steam in her breath. If he or Gallus were to breathe it in, it was like a supercharger for their dopamine levels. It frequently made one incredible feedback loop between the three of them. Sandbar wasn't sure if their relationship with Ocellus had created a 'changeling fetish', and the only reason why he didn't say anything of the sort was he thought it might be disrespectful to her.

But it was seriously like wearing for the first time all over again. He delighted in the muffled crinkles he heard with every step he took.

As they came to the main street headed north to the castle, they saw that nearly all the local eateries in town had set up kiosks offering their establishment's most popular items. Most of them had small lines, while more ponies filed down the center towards the front steps of the castle, where tables and chairs had been set up on both sides of the road. They had all been expertly enchanted, staying dry, warm, and free of snow.

The family decided to get hot chocolates all around as they took their seats at one of the larger round tables towards the back. Sandbar could barely tell how warm the chair was, as he was already sufficiently covered down there.

The group of five had gotten settled just in time, as Mayor Mare appeared up on the balcony to officially kick off the festivities.

"Good evening, Ponyville, and Happy Hearth's Warming Eve! I trust everypony has been enjoying themselves tonight, and now for the show you've all been waiting for, I happily present, your Captain of the Guard, Lieutenant Colonel Fizzlepop Berrytwist!"

Hooves all around the front of the castle tapped the tables and stamped the ground in applause for the beloved EUP captain as she came up to the balcony railing.

"Happy Hearth's Warming, Ponyville! Let's get this party started!"

As Sandbar sipped at his hot chocolate, he began to feel his bladder signal an urge to go. As it was his first time wearing outside, the trained, adult side of his mind kept hold for a moment. After a few seconds of reminding himself that he was padded, he took a breath and let it go, wondering what Ocellus was feeling as he felt the stream of urine connect with his living garment.

Ocellus wasn't sure what hit her mind first; the excitement and relief of Sandbar finally using her as this form was meant to, or the feeling of taboo and naughtiness as she realized she was essentially participating in a form of watersports, a fetish Trixie's summer class had very briefly touched on, but wasn't actually demonstrated.

She felt herself become bloated just slightly as she felt her form swell and expand as Sandbar's urine was taken into the absorbent layers of the diaper, and his feelings of love heightened further as he finished over the course of about twenty seconds.

Tonight was turning out to be quite the interesting night indeed...

When A Changeling Needs A Change, Part 2

Sandbar's mind was currently pulling him in two directions; the pure euphoria of enjoying a perfectly tailored diaper around his waist and held snugly against him by his winter clothes, and the realization that he had essentially just peed on one of his best friends. He tried not to focus on the latter too much, after all, Ocellus had to have known precisely what she was getting herself into, right?

Luckily, his mind couldn't dwell for too long, because Lieutenant Colonel Berrytwist's fireworks display began, and Sandbar's eyes and focus were drawn upward to the pyrotechnics lighting up the night sky as he continued to sip at his hot cocoa. The unicorn's pyrotechnic spells were almost better than a fully-staffed fireworks show. She put these on almost every holiday.

Sitting here in this clothing, watching these arcs of light and fire reminded Sandbar of one of his earliest foalhood memories that he could recall. He remembered not even being potty trained, but he remembered the fireworks. They weren't in front of a castle, but rather town hall, quite a few years before Princess Twilight Sparkle came to town and changed everything for the populace.

Once he finished his cocoa and chocolate-covered pretzels, Sandbar couldn't let go of how self-conscious he still felt. He heard every crinkle his changeling-turned-diaper made, and his mind was convinced that every other spectator also heard it over the roar of the fireworks. As his evening snack began to settle in his stomach, he felt the call of nature, his diaper-training taking a distant backseat because of the crowds, and he turned to Gallus, and nudged his side.

The griffon turned to look at the stallion's half-concerned expression.

"You need to head back?" Gallus asked, with his boyfriend nodding silently. Knowing the rules his parents had set forth, Gallus finished the last of his cocoa in a few gulps, and got up from his seat, Sandbar quickly following. Not wanting to interrupt his family's enjoyment of the show, he and the griffon left the seating area without a word, past the kiosks, and back towards the eastern neighborhoods.

As he distanced himself from the crowds, the reluctance of the pony's bowels started to fade, as Gallus noticed his gait become unsteady.

"You gonna make it, little guy?" He asked, figuring they were far enough away from the crowds to resume the ageplay talk.

Hearing such an infantile question was the last straw for Sandbar, and he stopped in his tracks and spread his back legs everso slightly. Gallus didn't hear the evacuation like he normally would be able to in their bedroom, due to the fireworks behind them, but he definitely saw the change in the pony's expression, how he suddenly drew in breath, his eyes widened, and he trembled for just a brief moment.

For a split second, Ocellus' mind wanted to be grossed out. But as the warm slimy ooze spread out over her, she was overcome with the taboo excitement and love bursting forth from Sandbar along with it. He felt so naughty, relieving himself, filling his pants in the middle of the street like that.

"Phew, you stink little bro. Guess you're still not ready for training yet, huh?" She heard Gallus say, sending another rush of excitement and embarrassment out of Sandbar. As everything started to settle, and she felt Sandbar's growing stallionhood press up against the front of this form, she continued to soak in the love he was excreting.

She didn't quite understand it, and figured she never truly would until she tried it herself, and decided that it was probably what she should ask them about next. But she absolutely had an idea of how much Sandbar loved it, and to a degree, how much Gallus loved watching over him like an older sibling. Right now, she was content to hold her transformation and be grateful that she currently didn't have a sense of smell.

As Sandbar stepped inside his house along with Gallus, he was honestly torn between getting out of his winter clothes and well used diaper, getting Ocellus cleaned up, or giving her one last piece of what he loved to much about the thick, squishy, crinkly garment.

"So, what next little bro? I'd say we've got about a half-hour to forty-five minutes before your parents get back." Gallus told the pony.

"Yeah, and I'm guessing this isn't gonna be like a regular change. Hmm... I'd say let's go to the shower and we can wash and rinse off once she changes back." Sandbar suggested. Gallus nodded and the two of them walked to the bathroom. Closing the door, the griffon turned on the shower head and got it to a comfortable warm temperature, and Sandbar quickly undressed down to his well-used diaper, and stepped over the side and into the tub, sitting down.

"Alright, Ocellus, get ready." He said, as he began to pull at the tapes. As they came free from the front landing zone, the pony let it flop down. It glowed a bright white, and after a flash, he felt himself get bumped up as he suddenly found himself sitting on Ocellus in her default arctic blue form. He quickly put his front hooves on either side of the tub and lifted himself up momentarily to allow her to slide out from under him. She sat up and turned herself around, sitting back against Sandbar, feeling his erection pressing against her back as the warm water washed over both of them as Gallus took the bottle of soap and drizzled it over both of them before he grabbed a washcloth and began getting them cleaned up. Sandbar did the same, grabbing another washcloth and began gently wiping the changeling's abdomen down.

"Well, that was certainly... Different..." The changeling commented, taking a quiet, deep breath, then slowly exhaled, a green hazy steam flowing from her mouth. Gallus and Sandar had grown accustomed to this 'venting' she did to prevent magic-filled shockwaves like the one that occurred during their first night together.

"The good kind of different?" Sandbar asked, a warm trickle of water falling from the tip of his mane down onto the changeling.

"Absolutely. In fact, now that I've experienced that, and now that I know a good part of what you get out of it, I was wondering if I could, well, join you? See what it's like from your end?"

Sandbar rinsed the washcloth off and went lower, finding how aroused she was at the moment, no doubt matching him as his stallionhood pressed into her back, twitching a bit.

"Well, that certainly sounds doable. What do you think, big bro?" The pony asked, looking up at the griffon, who smiled in return.

"Sure. Let's finish getting the two of you cleaned up, and get you and your new sister ready for bed."

Now the pony was excited. Gallus was a phenomenal caretaker, but he had never had a playdate before with another creature playing a similar age to his.

Their bodies clean, Gallus gave Sandbar's mane a quick wash, then shut off the shower, letting them step out and begin to drip dry on the bathroom rug while he went to go get dry, fluffy towels from the pantry.

"Alright, let's go get you two dried off and padded up."

When A Changeling Needs A Change, Part 3

Ocellus' excitement grew as she followed Sandbar and Gallus back down the hall to their bedroom. Now that she knew precisely the how's and why's of what the pony loved about all this, stepping in here nearly took on a whole new meaning. The past hour had been so arousing that she was worried that she had possibly left drippings on the floor during her walk from the bathroom.

Together the three of them approached the large changing table.

"Alright, Ocellus, you first. Upsies!" Gallus said, taking hold of her just behind her front legs and lifted her up almost without effort, setting her down on the soft padding on the top of the table. He leaned down to grab a fresh diaper, stuffer, and a bottle of powder. When he came up, setting all of these things beside the changeling, he got a clearer picture of how aroused she was between her legs, and her eyes were taking on green sparkles again.

The griffon unfolded the diaper, quickly got the stuffer placed in it, and lifted her backside up for a moment while he got it positioned underneath her. Even before it had been wrapped around her, she could tell how soft it was.

"Before we get you all padded up..." Gallus paused, glancing over to his boyfriend. "Sandbar, want to show your new baby sister one of your favorite things about being up on that table?" He asked, giving a wink.

The stallion blushed, knowing there was no hiding how stiff he was on his underside. It made the most sense, diapering him up in this state would be a tricky affair, and the tapes would certainly be less secure when it subsided if they didn't take care of it now. Ocellus' cheeks also tinted red when she knew what the griffon had in mind as Sandbar climbed the short steps up onto the table and stood above her, his erection already dripping a bit of pre down onto her clean diaper. The table was quite sturdy, it didn't even give a single creak as the weight of a nearly full-grown earth pony was added to the top. Sandbar placed his front hooves on both sides of the changeling's head, and got himself lined up between her back legs, and slowly entered her.

Ocellus let out a soft gasp, and the telltale glowing green steam escaped from her lips on the exhale. Sandbar breathed some of it in as the rest floated to the ceiling, getting a tingling sensation across his entire body in return. The steam that had reached the ceiling would slowly dissipate as it returned to the floor, which would take a matter of minutes.

Not content to merely watch the display in front of him, Gallus clandestinely grabbed the lube from the shelves of the changing table, quickly applied it, then mounted the steps, taking a firm hold of Sandbar's tail. It only took a moment for the pony to realize what was coming as he felt a lubed talon slowly poke and prod him for a moment. It was easy enough with the slow pace that he was rutting Ocellus; if it weren't for her magic this would be over in a matter of seconds, and she deserved a better Hearth's Warming present than that. Not that going slow made it super easy; the open diaper underneath Ocellus gave a crinkle with every thrust, and the sounds his diapers made was also always a rush to the pony.

"Sorry bro, but I can't just stand here and watch you two rut each other." Gallus told him as he got lined up. Ocellus felt Sandbar's rhythm falter as Gallus pressed into him, slowing as he let the griffon's girth enter his backside. The changeling had taken both of them separately before, and she had her favorite parts of both of them; namely Sandbar's medial ring, and towards the end, his flare. When it came to the griffon, she loved how smooth it was, and felt like she was being stuffed beyond her limit when it came time to insert the knot near the base.

Every time Gallus hilted in the pony, it sent him forward, and it took them a few moments to get a rhythm going. The irregular pattern that Sandbar's thrusts had taken had a certain endearment to Ocellus, as he struggled to concentrate on the pleasure originating from both ends. Every breath she took in contained love from both of them, and every exhale filled the upper portion of the bedroom with more green mist as she held on as long as she could. The eyes of her two partners began to glow green as the amount of residual changeling magic they had been breathing in started to reach a threshold.

"You ready, lil' bro?" Gallus asked, a somewhat rhetorical question, it really didn't matter. They wouldn't be able to hold the love in any more than Ocellus could without subjecting the rest of the neighborhood to it as a consequence.

"Ah, ah! I... I love you both so much!!!" Ocellus cried out.

Gallus was first by maybe a second. He hilted up his knot, then slowly but forcefully pressed further, and it popped in moments before he felt himself release. It wasn't quite as painful for the stallion due to the absolute euphoria that Ocellus' magic was providing. As he bottomed out in the changeling, he felt his stomach expand a bit, then he felt himself erupt into the bug. To the pony and griffon, their minds made it feel like fire hoses had been turned on. For Ocellus, she felt like the world's most absorbent living sponge, as a stream of green mist rose from her open mouth while she hit her own peak, releasing Gallus' and Sandbar's love just as soon as she took it in.

None of them were entirely sure on how long it lasted, and honestly, that was part of the fun. The next thing Sandbar felt was Gallus slowly pulling out of him, only to be replaced by a lubed up plug.

"Just want to save that for when you're padded up." Gallus said, knowing he'd have to finish the second half of his work once Sandbar pulled out.

The post-orgasmic lull was much slower when the changeling was present. No doubt they would all be exhausted and snoring in a bit, but it wasn't the expected drop in energy that normally accompanied the afterglow.

As soon as Sandbar pulled out, he stepped aside and Gallus took his place in between the changeling's legs, quickly grabbing the foal powder and giving Ocellus' nether regions a quick dusting before bringing the disposable garment up and taped it up snugly around her waist. She sat up and marveled at the thickness. Gallus scooped her up off the table and carefully carried her over to the open crib, laying her down before coming back to the table, where Sandbar had already climbed up. For the pony, it was business as usual. Getting his diaper fastened would be much less of a hassle now that his throbbing stallionhood had been taken care of. His big bro got a fresh diaper unfolded and palced underneath him, gave everything a quick once over with a wet wipe, and applied a dribbling of mineral oil. He took hold of the front of the diaper in one talon and took hold of the flared base of the plug with the other, and in one fluid motion, brought the turtle-patterened diaper up and popped the plug out in one smooth motion. By the time the pony's backside began to dribble and leak, the diaper was already taped up snugly, and Gallus was helping him into his new hooved pajamas.

"Happy Hearth's Warming, Ocellus. Happy Hearth's Warming, Sandbar. You're the best gifts a griffon could ask for."

The stallion and changeling were out like a light barely after Gallus had closed the front of the crib, and snuggled into each other, as seed dribbled out of both of them into their waiting diapers. They'd be quite sticky and wet for their morning changes, Sandbar probably more so, as he was well versed in wearing to bed.

The fireworks had died down outside, snow had continued to fall, and most of Ponyville's populace would no doubt be headed home for the night, save for the late-nighters who would be attending Pinkie's late dinner in the castle.

Gallus glanced up at the plastic glow-in-the-dark stars that had been plastered to Sandbar's ceiling, and saw how they had taken on a green sparkly glow from the fun that had just taken place under them. His gaze fell to his two significant others sound asleep in the full-sized crib, feeling a sense of pride well up within him.

Roleplay was roleplay, but this absolutely still felt like a real family.

"Sweet dreams, my special little ones." Gallus whispered, quietly going over and shutting off the light, letting the glow of the stars on the ceiling dimly illuminate the bedroom as he climbed into bed and got under the covers, feeling his eyelids grow heavy as he watched the snowfall outside the bedroom window.

Best Hearth's Warming ever.
