When I saw the bars of my brother’s crib, my mind struggled to rectify the strange sight. The events of the last night played out in my mind. A look down at my crotch revealed that I was, in fact, wearing my brother’s Pampers. I looked down at my paw and rubbed at the dye that obscured my identifying mark and noticed that it hadn’t faded in the slightest. My cousin Tyler had done really well at turning me into an identical version of my six-year-old brother. 

	Although I’m sixteen, I’m still a Riolu. We don’t get bigger after we’re born. Not until we evolve into Lucarios. My cousin used this fact to blackmail me into pretending that I was my bedwetting little brother. For what purpose, I can’t tell. Perhaps he just wanted to finally beat me at something. It was probably embarrassing losing in tournaments to a Riolu as a Lucario, even if I was five years older than him.

	In any case, I had to try to pretend to be my little brother as well as I could until Tyler was gone. If I didn’t, I’d never get back the aura he blackmailed from me. There was no way that I’d ever be able to compete in a tournament seriously ever again.

	I laid there for an hour, trying to go back to sleep. It was no use. My muscles twitched, begging for me to go on my morning run or do some pushups. I’d gotten so used to waking up at the crack of dawn and immediately starting my exercise routine.

	As fate would have it, although our family came from a long line of tournament fighters, my little brother had no interest in training of any kind, evidenced by the diaper I was wearing while I pretended to be him. Unlocking the crib to get up or trying to train in any capacity likely meant breaking my aura promise and losing my power forever.

	Another morning routine I had was using the restroom, and I was trying my best not to think about the fact that I would need to use the diaper eventually. Our parents had given up on potty-training him and let him embrace the diapers until he felt ready. This meant that he wasn’t day-time trained or nighttime trained. He pooped in his potty, which our parents were grateful for, but would still occasionally have accidents. Thankfully for me, it wasn’t frequently, so I didn’t need to mimic that behavior.

	Two hours passed and the need to urinate grew. I had to get it over with eventually, right? Swallowing my pride, I stood up in the crib and held onto the bars, positioning myself as well as I could so that I wouldn’t leak. The warm liquid flooded the plastic garment and I tensed up, waiting to see whether it would contain it all. I’d held it for quite a while, so I was quite surprised to see that the only visible indication was that the wetness indicators faded from the front. 

	It was humiliating to admit, but it felt kind of nice. The warm garment clung snugly to me. It almost felt like the feeling you get after getting into a warm jacuzzi. I tentatively laid back down in the crib, expecting the liquid to slosh out, but it didn’t. I pulled my little brother’s blanket over me and quickly found myself much more comfortable than I had been before. 

The shock to my system of peeing myself calmed down my muscles to the point that they stopped twitching. It was strange and I certainly had no muscle memory for what I’d just done, so my body just gave up and let me go back to sleep.

	 I awoke to the sight of my father’s face. “Good morning, sleepy boy,” he said. I felt flush beneath my fur. He was cradling me in his arms.

	“G-good morning daddy,” I said with more than a little embarrassment in my voice, the soggy garment still clinging to my waist.

	“It’s already noon. Your brother and your cousin are training,” he said, checking my diaper and giving me a sly look. “But you aren’t ready to start that yet, are you?”

	I shook my head, worried that I might give away the game if I spoke too much. I know that I’d need to get used to peeing in the diaper if I wanted to get out of the weekend intact, but his paw still surprised me as it confirmed the sogginess that I’d made.

	“It’s okay. You don’t need to grow up, yet. Your brother is a really strong fighter, you know? He could probably steal the title away from your uncle one day. You can just be our little Riolu for as long as you want. Your brother can handle the family name,” he said, laying me back onto the crib. 

	I was blushing for more than one reason. My father rarely, if ever, gave me praise. Of course, he didn’t know that my little brother and I had switched places. The second reason was that he was changing me into a new diaper. I couldn’t deny that my father’s touch felt comforting as he wiped me down and powdered me up. It was strangely intimate and I didn’t mind the blow to my pride as much as I thought I would.

	“There you go. You’re all set to play with your cousin,” he said, finishing the process and pulling a pair of cargo shorts over the diaper and a t-shirt with some cubby show my brother enjoyed over my top. “They should be finishing up with training soon. First, let’s make sure you get some food in you, huh?”

	I nodded, holding tightly to my father as he carried me into the kitchen and sat me in my little brother’s highchair. I’d completely forgotten that this was a thing we owned. For the most part, I ate prepared meals designed for nutrition that came in a powdered meal form. It had been a long time since I’d eaten anything homemade. 

	He had a prepared plate of macaroni and cheese that he placed down on the tray. He walked away once he did and I was left alone with just the plate and the television playing the show from the shirt.

	I wanted to tell him that he hadn’t handed me any utensils, but I realized that he likely hadn’t meant to. That’s right…although I’d never been around to watch him eat, I knew that he didn’t care to use utensils because he always made a mess of himself whenever he ate.

	Stifling my urge to jump from the high-chair and get some silverware from the drawer, I picked up a single piece of the cheesy macaroni, grimacing at the ooziness of it. Just from that little bit, I licked the sauce from my paw and took it into my muzzle. It was surprisingly good. I hadn’t remembered my dad being able to cook anything. 

	My stomach grumbled. I was very hungry. The last thing I’d had to eat were the berries that Tyler gave me last night which had placed me in this predicament. Shoving my pride into a deep corner of my mind, I began shoveling the macaroni in my maw, feeling the cheese occasionally splash on me and the tray.

	I’d surprisingly cleaned my plate of all of it, but my paws, muzzle, and shirt were a mess of sticky bits of cheese. I don’t think my little brother himself could’ve done a better job. I quickly came to regret it as the minutes passed and the only thing I could do was watch my little brother’s show in my mess. It was a lot more entertaining than I remembered, though. I found myself rooting for the characters and lost in it until I felt a paw rub something warm against my muzzle.

	“Silly cub,” Tyler said, his face a mixture of sweat and pride. Apparently, the pair were back from their training. I was a little surprised to see my little brother Kevin there with my athletic gear on, especially because there were the telltale signs that he’d actually done some training.

	I let him wipe my muzzle and paws clean with the warm rag. I’d been sitting in it for a while and I didn’t care that Tyler was the reason that I was placed into this predicament. His paws lifted me from the high-chair, performing a check on me while he held me in the crook of his arm. I hadn’t wet myself since that morning when I had no other choice, but it was still humiliating to have his paws inspect me in that way.

	“How’s my little Kevvy doing, huh?” he said, cooing in that way that I hated.

	“Good,” I said simply, looking over to my little brother and my father who didn’t seem to be taking any notice that something was amiss. I sighed inwardly. I had no idea how he’d gotten my little brother to be complicit in this. He hated training. When I inspected him, he didn’t appear to be unhappy, though. On the contrary, a smile was plastered over his muzzle.

	He carried me into the bathroom and had me properly wash my paws, which I was more than pleased to cooperate with, sans the humiliating step-by-step instructions. He had a devious grin on his muzzle as he said, “we’re going to take you to the park Kevvy. So we’ve gotta get you all nice and clean.”

	Getting into the car was a humiliating prospect. My little brother hated car rides. As a result, I was forced to suckle on the pacifier which sapped my strength while they strapped me into his car seat. It was completely unnecessary, in my opinion. Once I was in, my brother had a Chansey mobile that sung him to sleep during the ride. I was forced to listen to the childish rhyme and allow myself to succumb to its effects.

	I was woken up by Tyler in the boy’s restroom. After a moment of investigation, I realized that the pacifier was in my muzzle and I was laying on a changing table.

	“Good afternoon, little peepants,” he said, placing his paw firm on my exposed diaper. It was, to my surprise, wet. Had I had an accident? 

	I started to remove the pacifier, but caught myself, realizing that I was still supposed to be my little brother. He would never have willingly done the same. Instead, I swiveled my head to the side to see my little brother standing there, pulling on the dry Pampers I’d been wearing a moment before.

	“You see, your big brother Nicky had an accident in his Pampers and since you were wearing a dry one, we figured we’d change him into yours. Unless you’d rather he go without it and piddle his pants like a toddler.”

	I just suckled on the pacifier. I couldn’t really do anything about it, could I? Even if I wasn’t a fan of him wearing a diaper while he was pretending to be me, I preferred that over him having accidents. I wasn’t a fan of being in my brother’s piss, but it was better than the alternative.	I wanted to ask both of them so many questions, but I simply couldn’t. I just had to go along with it.

	“You’re such a good little baby brother to Nicky. I’m sure he appreciates it,” Tyler said, pulling up my pants back over the soaked diaper.

	Playing at the park was a sort of training, right? My body felt a sense of relief as I propelled myself slowly over the monkey bars, taking my time and doing my best to make it seem like it was a struggle. I’d taken Kevin to the park many times before, so I knew what he was capable of. I wasn’t doing anything that he couldn’t and it took my mind off of the fact that I was basically playing in the park with a soaked diaper on.

	After a few minutes, the other children were watching me, so I reassessed how I was going about everything. Was I doing something strange? They just kept staring at me, so I plopped down in the sand pit and started building a castle. Nothing weird about that, right?

	Once I plopped down, however, I recognized the problem. At some point, my pants had been taken. I don’t know how or when, but I had been running around in nothing but my obviously wet diaper. Blushing, I just kept shaping the sand as if nothing was wrong, but I was trying to hide my embarrassment.

	I heard the footsteps behind me and I didn’t react even though I could tell from the sound of them that something aggressive was about to happen. The hackles on the back of my neck raised as I felt cold mud poured down the back of my diaper.

	I yelped, standing up and forcing the cold mushy mixture to travel further down my diaper. A Tyrogue was standing there, laughing. “Look! The little baby Riolu pooped himself!”

	I blushed, holding the seat of my diaper to prevent the mud from spreading more. It was a mushy mess and it discolored the diaper to make it seem like I’d actually pooped myself. The Tyrogue took the opportunity to shove me backwards, causing the mess to spread even more as my paws flung to the side to catch myself. 

	Real tears welled up in my eyes as I saw the young Pokémon surround me and point and I got up as quickly as I could, looking for my family. I sprinted awkwardly away from the pointing and laughing youngsters into the paws of Tyler who lifted me up. 

	He shushed me, cooing and cradling me as he started walking away from the taunters. “It’s okay. Accidents happen. We can get you changed when we get home.”

	I didn’t care that he’d put me in this mess at the moment. The comfort was sincere and I could only nod my head with the tears still welling up while I sniffled to fight them back. The pacifier was placed in my muzzle and I sought comfort in it, suckling it and letting the strength fade from my body.

The rest of the park venture was quiet. My father and brother were in a nearby shop buying groceries, so we were forced to wait for him to get back. The Pokémon children still taunted from nearby from time to time, but they didn’t dare approach the towering Lucario. I think this was the first and only time that my cousin had defended me in anything.

I was put into a new diaper before we left and fell asleep with the mobile. This time, I woke up as soon as we arrived home. I kept thinking I was going to be punished for ‘messing myself,’ even it was mud. No mention was made of what had happened by my brother or father. I suppose it was only natural, since these sorts of things happened with my little brother all the time and he was never disciplined for it.

I’d only need to bear with it for a while longer. My mom and aunt were supposed to be returning at night. It was a weekend getaway and I’d had more than my fair share of my cousin. He didn’t taunt or tease, aside from the occasional diaper check which was standard. I had to pee, but I knew I could hold it until they got back. I’d had enough diaper changes for a lifetime.

	We spent the rest of the night watching family movies and playing some card games. I kept the pacifier in my muzzle to prevent giving away anything until the end and my little brother was going to bed early as I normally would.

	When my mother came back, I found myself unable to contain my excitement, sprinting for her and hugging her leg. I was ready to be done with all of this.

	My cousin took me into ‘my room’ and placed me in the crib. “You were a very good boy this weekend, little Kevvy,” he said, placing his paw on my head as I felt the return of my aura, surging back.

	I hopped to my feet and spat out the pacifier, still feeling a little bit woozy from the rush of power returning. “Why?” I asked simply, looking him in the eyes.

	He pat me on the forehead and I didn’t balk at his touch. He wasn’t being aggressive. “Kevin wanted to try his paw at being the big brother. He thought it’d be fun. You’re too serious to play a game like that, so I thought I’d convince you another way.”

	“This was Kevin’s idea?” I asked, obviously not believing him. Why would my little brother want to do something like this? He thought back to all the times that Tyler teased him about being little and even spreading the rumor that he was a bedwetter. “No. This was your idea. You just wanted to see me humiliated.”

	Tyler smiled, holding up the phone with the picture of me asleep in a wet diaper before he’d switched our markings around. “I guess a little bit of me guided him along that path. But I guess you’ll be my good cousin from now on if you don’t want these to spread, huh?”	

	I grumbled, nodding my head. If it got out that I was a bedwetter, staged or not, it’d be hard to maintain the composure that I needed to compete in tournaments. 

	“Besides. You know that Lucarios possess mind-reading capabilities. You can’t tell me that you didn’t enjoy it a little. I know better.”

	I blushed but didn’t look away to give away the fact that there was an element of truth to it. 

His smug look told me that he’d seen through it. “The dye won’t fade for a month or so. You could paint over it, but I have a feeling that you might enjoy being a little Riolu as much as your brother enjoys being the bigger one. Have a good week, Kevvy.” 

As he walked away and closed the door behind him, I was left alone in the darkness. I could get up now. I could do whatever I wanted.

I pulled my little brother’s blanket over me as I laid back down, activating rest. When I woke up in a wet diaper in the middle of the night, I smiled, not needing to use the ability a second time in the warm embrace of the garment.
