{Pokémon/Diapers} Dirty Diaper Debacle

Story by SillyLittleSnivy on SoFurry

, , , , , , ,

Due to more demands of responsibility from her mother, Roselia is met with the task of taking care of her baby brother, Poipole. Unfortunately for Roselia, Poipole and his dirty diapers always seem to throw a wrench into her weekend plans one way or another.


(Brief content warning: This story is marked as mature for containing an instance of hypermessing and for being among the more fetish-oriented of my stories.)

It was a rather pleasant Sunday morning, a time for many to relax and take a bit of time off before the adults returned to work and the children continued on with their school year. Pokémon both young and old were adept at making the most out of their weekends, and Roselia was no different.

In the comfort of a soft pillow and warm blankets, Roselia contently lays in her bed while the morning takes its course. Ever since she started high school, her life had become a lot busier and a lot more stressful, so she was always one for sleeping in when given the chance.

While she remains fast asleep, Poipole crawls into her bedroom, waggling his little tail and suckling on his violet colored pacifier while the thick diaper between his legs softly rustles and crinkles. With a playful giggle, he crawls to Roselia's bed and climbs onto it, staring at his sleepy sister while he sits on top of her.

Roselia squirms in response to this disturbance before slowly opening her eyes to her little brother staring at her with wide eyes.

"Hi, big sis!" Poipole giggles and playfully pokes Roselia's face, but this doesn't amuse her in the slightest.

"Poipole...can't you see I'm trying to sleep?" she says with a groggy groan before closing her eyes again, doing all she can to ignore her baby brother.

The little Poison-type continues to suckle on his pacifier and sit on top of Roselia, but a loud gurgle comes from his tummy once some time passes.

"Mm-mmmph..." a strained expression forms on Poipole's face as he squirms and grunts.

BRAAAP! PPBLORP!!

His diaper is suddenly flooded with a mushy and liquidy mess, causing it to expand and stain a dark shade of brown as he stinks up the bedroom. The rancid stench quickly strikes Roselia's nostrils and her eyes quickly open again.

"Aaaaagh, geez, that smells horrid!" Roselia cringes and plugs her nose. "Did you really have to do that while I was trying to go back to sleep? Gosh, you're so disgusting!"

Poipole simply continues suckling his pacifier and a dopey grin of relief forms on his face as the mushy mess continues spreading around his diaper, not really understanding why his sister was bothered by such a thing.

"Baby brothers are the worst..." Roselia angrily mutters under her breath, greatly upset that a dirty diaper had ruined her plans of sleeping in.

With a sigh of exasperation, she gets out of bed and lifts Poipole by the waist, his full diaper drooping and dangling between his legs while she takes him downstairs. However, as upset as she was at the moment, Roselia found some solace in knowing that she wasn't going to be the one responsible for cleaning up whatever kind of foul and nasty mess was lurking in her little brother's diapers.

"Mom! Poipole's stinky!" she walks up to her mother Roserade and offers Poipole to her.

"Well, I was actually thinking that you could be the one to take care of your brother today." Roserade replies.

"A-are you serious?" Roselia replies with an expression of shock. "Please tell me you're joking, Mom."

"Not at all, dear." Roserade replies with a gentle smile. "I figured that it's about time I gave you some more responsibility now that you're no longer a middle schooler, so taking care of your little brother will be a good start to that."

"Moooom, why can't I just start that responsibility stuff later?" Roselia whines. "I'm gonna hang out with my friends today and I have better things to do."

"Because, Roselia, life is only going to get busier and full of more responsibilities. You'll hate me for it now, but I'm just getting you prepared for life before you're out of high school."

"Ugh, fine..." she says with another groan.

Roselia makes her way to Poipole's room and quickly lays him on the changing table. While she gets the needed supplies, Poipole innocently giggles and playfully wiggles his feet as he waits to get his diaper changed.

"You think this is funny?" Roselia says, casting an annoyed glare at her brother.

Slowly, she undoes the tapes and takes off his dirty diaper, though she immediately cringes at the repulsive odor and the sight of the mess that's spread all over his legs and bottom.

"Ewwwww, that's so gross!" she winces and delicately picks up the dirty diaper before dropping it into the trash with a loud plop.

Roselia then grabs multiple wipes and cleans him up ever so slowly, wincing and recoiling with each reluctant stroke of the wipe. After what felt like an eternity, Poipole's bottom is all cleaned and Roselia heaves a drawn out sigh of relief.

"Phew....finally done with that. The rest of this shouldn't be all that difficult."

From there, she applies some powder onto her brother's bottom before putting a clean diaper under his legs and snugly taping it around his waist.

"Tank you!" Poiple says cheerfully.

Roselia silently nods and picks him up off the changing table, bringing him downstairs and taking the pacifier out of his mouth before sitting him in his high chair.

"Now was that really as bad as you thought?" Roserade asks her with a chuckle.

"Even if it wasn't, I'm not exactly looking forward to changing his diapers again." Roselia replies with a shrug while she grabs a box of cereal from the pantry; she then grabs a small bowl and pours some cereal into it before giving it to her brother.

While Poipole happily picks at his cereal and eats it with his hands, Roselia makes her own bowl of cereal and cuts up some fruit for herself before sitting down at the kitchen table and making rather quick work of her breakfast.

"Sweetie, don't forget to feed your brother his formula." Roserade tells her.

"Oh, right." she gets up from the table and grabs a baby bottle from the counter, filling it up with the formula and placing it in the microwave for a brief minute.

Once the bottle finishes heating up, the little Poison-type excitedly smacks his hands on the high chair and his eyes follow the bottle while his sister takes it out of the microwave. Roselia then lifts Poipole out of the high chair, holding him in one arm and the bottle in the other arm.

"Gimme gimme!" he makes grabby hands towards the bottle.

Roselia inches the bottle closer to him and Poipole quickly nabs it, widely smiling and kicking his feet as he suckles on the nipple and drinks the creamy formula. Roselia can't help but crack a smile while she continues to hold Poipole; even if she thought her baby brother could be a nuisance, she couldn't deny that it was an adorable sight watching him happily drink up his formula.

"Well, it's a good thing feeding you doesn't seem to cause any problems." she says to him before taking the empty bottle out of his mouth.

Poipole pats his tummy in satisfaction, but he immediately feels something come back up due to emptying his bottle too quickly. Suddenly, he spits up some of his formula and it splatters onto Roselia's face.

"Or at least I THOUGHT feeding you wouldn't cause any problems." Roselia's smile immediately turns into an angry frown. "Now look at what you've done! You've gotten my face all yucky and it's all your fault!

"Roselia, cut your brother some slack." Roserade says to her. "It's not like he's deliberately trying to mess with you. Babies spit up all the time, you know."

Roselia groans in response; she knew her mother was speaking the truth, but it did nothing to quell her feelings of annoyance.

"Now if you'll excuse me, I'm going to clean myself up." she says before setting her brother down.

Roselia then walks to the bathroom and washes her face with a wet towel before also giving her hands a thorough cleansing, ridding herself of any lingering scents that may have carried over from that first diaper change.

"At least hanging out with my friends will serve as a much needed break from my babysitting duties." she says to herself before brushing her teeth and leaving the bathroom.

Now in a slightly better mood, Roselia walks back to her bedroom and scans her closet. She eventually takes out a bright yellow shirt and a light green skirt, quickly dressing herself up before heading back downstairs. While walking to the front door, she spots Poipole sitting on the floor and occupying himself with a toy truck, giving Roselia the impression that her job was done for now.

"Ok, Mom, I'll see you in a bit. My friends are probably waiting for me." she says as she opens the front door.

"Sweetie, aren't you forgetting a certain someone?" Roserade asks her.

"Huh? What are you talking abo-" Roselia stops and immediately connects the dots. "Oh, come on! You seriously want me to take Poipole with me?"

"Yes I do." Roserade replies. "Don't think that hanging out with your friends means you're off the hook with your little brother."

With an exasperated sigh, she walks over to Poipole and picks him up.

"What awe we doing now, sis?" Poipole asks as he's carried back to his bedroom.

"I guess you're gonna be meeting my friends now cause Mom insists you tag along with me." Roselia says as she sets him down and looks through his closet.

"Oooh, dat sounds so fun!" he smiles joyfully hops in place.

"Yea, for you it is..." she bitterly mumbles under her breath.

Roselia grabs a red t-shirt after looking through the closet for a little longer, putting it over his head and guiding his arms through the holes.

"Alright, now you better not mess things up when I'm with my friends." Roselia says to Poipole as she picks him back up and leaves his room. "You already ruined my plans for sleeping in, so I don't want you ruining anything else, got it?"

"Hehehe, okie!" the little Poison-type gleefully giggles as he's placed into a black stroller and taken outside.

While she gently pushes the stroller, Roselia smiles and breathes in the fresh morning air, taking some comfort in knowing this warm and pleasant weather couldn't be tainted by her brother at the very least. After several minutes of walking, she spots her friends standing on the sidewalk of a cul-de-sac with small houses surrounding it; a Leafeon in a black shirt and blue jeans and a Maractus in a light blue shirt and yellow skirt are seen patiently waiting for her.

"Hm? What's with the stroller, Roselia?" Leafeon asks her, lifting a confused eyebrow. "You never told us you were bringing a baby along."

"You can blame my mom for that, Leafeon." she replies. "She's assigned me with taking care of my baby brother because 'responsibility'." Roselia makes air quotes with her hands when saying that last word.

"Hi, big sis' fwends!" Poipole looks at the two Grass-types with a cute smile and happily waves at them.

"Well, I don't see the problem with this, cause your baby brother is absolutely adorable!" Maractus beams with joy and walks up to the stroller. "Can I hold him? Just for a little bit?" she asks Roselia.

"I don't see why not." Roselia replies with a chuckle.

Maractus lifts Poipole out of the stroller, causing the little Poison to fidget and giggle.

"Who's a cute baby boy? Who's a cute baby boy?" Maractus says in a playful voice as she lightly tickles his tummy.

Poipole babbles happily and bursts into a fit of laughter, taking quite a liking to the cactus Pokémon. Maractus plays with the little Pokémon some more, though it's not long before her fellow Grass-type friend starts to grow impatient.

"Not to sound rude, but we came here to hang out and I'd like to get started on that." Leafeon says to Maractus.

"Hehe, sorry, I suppose I got a bit caught up with this little cutie." she nuzzles Poipole's cheek and puts him back in the stroller. "Any who, is anyone opposed to heading over to the café first?"

"Not at all." Roselia replies, cracking a smile. "I could definitely go for something to drink right about now."

With that decided, Roselia turns around and gets back to pushing the stroller while her friends walk beside her. As several minutes pass and they head into town, Roselia had to admit that taking a stroll with her brother was quite enjoyable.

"Perhaps I was overreacting to those morning mishaps a little bit." she says to herself.

Likewise, Poiple was also enjoying this stroll, gazing in awe at the wide variety of shops and eateries as he takes in the surroundings of the vibrant and bustling town. However, the little Poison-type takes his eyes off those surroundings and looks down at his diaper when his tummy suddenly gurgles and a notable pressure forms in his bowels as the cereal and formula make their way out. Poipole then tenses up and spreads his legs, making room for the mess he was about to make in his diapers.

"Hnnnnnng..." he grunts and kicks his feet, squirming and fidgeting in the stroller as he prepares to drop a stink bomb.

PBLOOOOORMPH!!!

Poipole pushes a large and stinky mass into his diaper, causing it to expand as a soccer ball sized lump bulges out from it; a dopey smile forms on his face, though the same can't be said for the other Pokémon.

"Ugggh, Poipole! You pooped your pants again?!" Roselia groans in annoyance; at the very least, being half Poison-type made her somewhat used to these foul odors, though her pure Grass-type friends didn't have that luxury.

"Euuuugh, nasty..." Leafeon's face grows pale and the pungent stench makes her gag. "I think I just threw up in my mouth from that. Gosh, he really stinks..."

"I...have to...agree with... Leafeon here..." Maractus says in a strained and nasally voice as the stench overwhelms her senses. "Your brother...is cute...but...he smells...awful" she adds with a series of coughs.

"I think we should just hang out another time..." Leafeon says as she squeezes her nose. "I'm gonna vomit if I have to deal with that smell any longer..."

"Wait, but-"

Before Roselia can say anything else, her friends run off in the distance, not being able to handle that nasty odor any more.

"Hm? Whewe did youw fwends go?" Poipole asks innocently, oblivious to the stench coming from his full diaper.

"You pooped yourself so badly that you drove them away..." she replies with a sigh. "You smell terrible, you know that?"

"Huh? But I don't smeww anyting." the diaper-packing Pokémon says in confusion.

"Never mind..." Roselia says with a shrug. "Let's just head back home."

Poipole simply kicks his feet and observes his surroundings while his sister turns around and gets back to pushing the stroller, seeming to have no issue with the big and stinky lump protruding from his own diaper. While they head back home, he feels a pressure developing in his bladder, but this doesn't bother him either.

PSSSSSSSSSH!

Poipole's bladder relaxes and he smiles as a pleasant warmth envelops the front of his diaper, causing it to swell up some more and discolor yellow. Once his bladder empties, he gives his full diaper a playful pat, giggling as it makes squishy and squelchy sounds.

"Finally home..." Roselia eventually stops pushing the stroller and she cracks a relieved grin, though her mood is quickly soured when she picks Poipole up and notices the yellow stain on his already full diaper. "As if you haven't already done enough damage to that diaper..." she says with an annoyed sigh.

Once Roselia steps in the house, her mother eyes her from the living room and looks at her curiously.

"Oh? What's got you back home so early?" Roserade asks her.

"My friends ended up having other pressing matters to attend to, so we ended the hangout early." while Roselia was being truthful to a certain degree, she figured she'd tell a white lie to spare herself from explaining the dirtier side of the details. "I guess that just means I have more time to spend with my baby brother." Roselia feigns a smile to stop any further conversation, though at the same time she's trying her best to not recoil from the stench of Poipole's packed diaper.

"Well, then I'm glad you're getting along with your little brother." Roserade replies with a smile.

Roselia then takes Poipole up to his bedroom and lays him on the changing table, her feigned smile immediately shifting to an angry frown once she escapes the sight of her mother.

"I don't know how you did it, but you somehow smell even worse than last time..." she says with an exasperated groan while she undoes her baby brother's diaper and dumps it into the trash with a loud and squishy plop.

Poipole just playfully giggles in response while Roselia lifts up his legs and cleans up his bottom with multiple wipes and large amounts of baby powder. Once that's done with, Roselia slides a clean diaper under his legs and snugly secures the tapes around his waist; she was certainly getting better at diaper changes, but that didn't assuage Roselia's anger.

"First you ruin my chance to sleep in, then you ruin the hangout I planned with my friends! All because Mom wants me to be the one changing your diapers today!" Roselia says with a pouty cross of her arms.

Rather than paying attention to what his big sister is saying to him, Poipole hops off the changing table and waddles to a pile of toys in the corner of his room; after rummaging through the pile for a few moments, he returns with a blue rattle and a green rattle in each of his hands.

"Pway?" Poipole smiles innocently and offers Roselia the green rattle.

Roselia wanted to stay angry at Poipole, but she couldn't deny that a mindless diversion like shaking a rattle could possibly take her mind off of this hectic morning.

"Oh, alright...I'll play with you." she shrugs and accepts the green rattle.

While Roselia half-heartedly shakes her rattle, Poipole shakes his blue rattle with great enthusiasm and wiggles his diapered bum as does a playful little dance. Roselia wouldn't partake in any kind of dancing, but she couldn't help but crack a smile at her brother's playfulness. As the rhythmic sounds of shaking rattles continue to fill the room, Roserade soon makes her way up to check on the siblings.

"Sounds like you two are having fun!" she says cheerfully.

"Mmhm! Mmhm!" Poipole replies with an affirmative nod of his head.

"I bet all that playing around has made you guys hungry though, right?" Roserade asks with a giggle.

"Now that you mention it, yes." Roselia replies with a giggle of her own."

"Great! Cause I've got a little outdoor picnic set up in the backyard!" Roserade says before turning around and heading outside.

Roselia picks up her baby brother and follows her mother from behind, spotting a red picnic blanket and a few platters of sandwiches and fruit upon stepping outside.

"I figured you could use a short break from your responsibilities, so I'll feed Poipole this time." Roserade says before taking Poipole out of Roselia's arms and spoon feeding him fruit and bite-sized pieces of a sandwich once she sits him on the blanket.

Roselia heaves an inward sigh of relief and sits down with her family. In spite of all the chaos that came with taking care of her little brother, if there was any silver lining to this situation, it was that said chaos made her more appreciative towards the scarce amount of free time she would receive; Roselia cherished the warmth of the sun's rays caressing her body and the peace and quiet that came with an otherwise uneventful meal of sandwiches and fruit. After finishing up her lunch and salvaging all that she could get from her free time, Roselia stands up and walks off the grass.

"Okay, Mom, now I'm gonna study for my big math test." Roselia says as she starts making her way back inside.

"Sweetie, don't think you're gonna weasel your way out of your responsibilities." Roserade says with a chuckle. "I did say you were taking care of your brother for the whole day, so I'm giving you the full package of responsibility."

"Mooooom, come on! "Why can't I just take care of him once I'm done studying?"Roselia says with a pout.

"Because, sweetie, if you ever decide to have kids of your own, you'll realize that you don't always get to choose when you do and do not have to take care of them." Roserade says as she hands Poipole back to her. "You'll hate me for this now, but as a single mother, it's my obligation to prepare you for child care now in case you end up like me and don't get the luxury of having a faithful husband."

"Fine..." Roseila heads back inside and takes Poipole to her bedroom. "Just don't be a nuisance, ok?" she plops Poipole onto the floor and sits at her desk, opening her math textbook and getting out a notepad as she prepares to study.

Poipole tries his best to keep this promise, but he has too much playful energy to simply sit still and not make any noise. Curious as to what contents lurk within Roselia's textbook, the little and nimble Poison-type quickly climbs onto her chair and hops onto her desk, staring in awe at the many numbers and formulas that fill up the book.

"Poipole! What did I just tell you?" Roselia says with a frustrated glare.

"But big sis! Wook at aww dese numbahs!" Poipole replies as he continues to stare at the book and starts getting drool on its pages.

"Yes, there are lots of numbers in a math textbook, Poipole, now please get off my desk." she says with a groan.

"But I can hewp you study!" he replies with a cheerful smile.

"I appreciate the gesture, but I don't think someone like you who still makes doo doo in his diapers could help me with trigonometry and pre-Calculus." Roselia replies.

"B-but I wanna hewp!" Poipole gets teary eyed and starts to sniffle.

"No no no! Don't cry!" Roselia takes Poipole off her desk and rummages through her closet, eventually finding an old teddy bear from her earlier years. "Here! You can help by keeping Mr.Teddy

company!" she hands the bear to him.

"Ooh! Okay!" Poipole's tears fade away and he happily hugs the teddy bear.

Roselia then sits back down and tries to get back to studying; the sounds of stomping feet and crinkling diapers can be heard while Poipole toddles around the bedroom, but this doesn't seem to have much of an impact on her focus as more time passes.

Unfortunately, Roselia would soon be on the receiving end of an unpleasant surprise when Poipole's lunch starts approaching its way out and his bowels beg for release. The little Poison-type squats and tightens his grasp on the teddy bear, straining and grunting as he prepares to do the deed once again.

BLOOORMPH!!!

Poipole makes a big poopy in his pampers, causing them to immediately slump onto the ground as a repulsive odor now emanates throughout Roselia's bedroom.

"Uggggh, are you kidding me? Did you really have to do that right as I was starting to get focused?" Roselia stands up and lifts him up. "It's like you're deliberately trying to make my day as difficult as possible."

Poipole looks down at the full diaper between his legs and giggles as he gives it a playful pat, seemingly paying little attention towards whatever his sister was saying to him.

"Whatever...let's get you cleaned up." Roselia shrugs and makes her way back to Poipole's bedroom before laying him on the changing table and getting the supplies organized.

Poipole maintains his grasp on the old teddy bear while he receives his third diaper change of the day, playfully giggling and hugging the stuffed animal as he gets cleaned up. Roselia then picks him up and returns to her bedroom once he's diapered up.

"Hopefully that's the last time you disturb me. Now if you'll excuse me, I have more studying to do." Roselia plops her little brother back onto the floor and sits back on her desk.

Roselia tries everything in her power to maintain a sense of focus, but the continuous chaos of caring for her baby brother ends up making her too deprived of energy to study efficiently. After slowly trudging her way through some practice problems, she abruptly turns around when her brother nudges her in the side.

"What did I tell you about disturbing me?" Roselia says with angry glare, feeling like she's on the brink of losing her mind.

"I hungwy, big sis." Poipole innocently replies.

"Oh... I suppose that's a valid reason for nudging me." Roselia takes a deep breath and regains her composure. "Now that you mention it, I could go for some dinner too."

Roselia then picks Poipole up and heads downstairs, placing him in his high chair before walking to the fridge and skimming through its contents; being far too tired to make herself a hearty meal and deal with feeding her brother again, she opts for something simple and grabs a box of bite-sized chicken nuggets.

"Ooh! Chicken nuggies! Chicken nuggies!" Poipole smiles and happily claps his hands.

"Glad you're happy with those, cause I'm too tired to make anything else." Roselia says before putting all of the nuggets on a plate and placing it in the microwave.

After a few minutes pass, the microwave beeps and she takes the plate out, sliding half of the nuggets off the plate and onto Poipole's highchair before sitting down at the kitchen table. While her brother grabs handfuls of nuggets and shoves them into his mouth, all Roselia can do is slowly nibble at her food as a wave of drowsiness comes over her. Once she eventually finishes her dinner and throws the plate away, Roselia spots her mother walking towards her.

"Well, looks like you've had your work cut out for you today." Roserade says to her. "All you have to do is put him to bed and you're done for the day!"

"Oh thank goodness..." Roselia walks up to the highchair and lifts Poipole up from it. "Alright, let's get you to bed."

Too exhausted to even bother putting a pair of pajamas on him, Roselia simply plops him into his crib and puts the blankets over him shortly after reaching his bedroom.

"Good night, big sis!" Poipole says cheerfully.

All Roselia could muster was a tired nod of acknowledgement before she heads back to her own room; she was certainly glad to be done with taking care of her brother, but any feelings of relief were quickly

replaced with feelings of utter exhaustion.

"I should.:.probably study a little longer." Roselia says as she walks back to her desk and sits down.

Unfortunately, today's events had left her far too tired for such things. After only doing a few problems, Roselia's eyelids grow heavy and she immediately falls asleep on her textbook. Once several hours pass and the evening shifts to next morning, Roselia wakes up with her face pressed into the textbook.

"W-what happened?"

Roselia stretches her arms, but the unfortunate realization quickly hits her when she notices that she's sitting at her desk and wearing the same clothes from yesterday while the morning sun peaks through her window.

"Crap! I must have conked out while I was studying!"

As if that wasn't bad enough, things got even worse when she was struck with another unfortunate realization; on top of having a big math test, she also had a show and tell presentation for her first period class, something that had completely slipped her mind due to yesterday's responsibilities.

"CRAP!! I also have a show and tell presentation I completely forgot about! Uggghh, and it was all because of my stupid baby brother! I need to give him a piece of my mind..."

Roselia then grabs her backpack and angrily stomps her way to Poipole's room, though he just greets her with a cheerful smile.

"Hi, big sis!" Poipole says while he happily bounces in his crib.

"Poipole...you...."

Roselia was about to lash out at her brother, but a sudden idea comes to mind before she can do anything of the sort; rather than arriving at her presentation empty handed, she figured that her little brother could be her show and tell prop as a last resort idea.

"You....are coming to school with me today!"

"Oooh, okay!" Poipole replies.

Deciding that she'd go through with this snap decision of hers, Roselia stuffs a few diapers and changing supplies into her backpack before taking Poipole out of his crib and rushing downstairs. While she puts her backpack and her shoes on, her mother looks at her in confusion.

"Roselia? Why are you bringing Poi-

"Gotta head off to school now! Love you, Mom! Bye!" Roselia abruptly heads out the door before Roserade can even finish her question.

Roselia storms outside and rushes her way to school, panting and breaking a sweat all while her brother delightfully giggles and squeals in response to his sudden piggyback ride. Several minutes later, she frantically makes her way to the classroom and the rest of the class immediately fixates their attention onto her.

"Oh! There you are, Roselia! I was just about to call you for attendance!" a Bellossom says to her with a warm smile. "Are you ready for your show and tell presentation?"

"Sure am, Mrs. Bellossom!" Roselia says, feigning confidence with a smile while she takes Poipole off her back. "This is my baby brother, Poipole, and he's gonna be gonna be the prop for my presentation today!"

"Well, I can't say we've had anyone bring in their sibling for show and tell, so I applaud you for thinking of something unique." Bellossom says to her. "So, care to tell the class why you made your little brother the focus of your presentation?"

"Well, having a Poison-type for a little brother inspired me to do research on the ways parents raise Pokémon of different types, so I brought him here to show you how raising a Poison-type is a far different experience from raising other Pokémon." Roselia says with a confident smile to hide the fact that she was improvising everything.

"Ooh, then tell us more about your research." Bellossom says with a curious raise of an eyebrow.

"Oh boy, where do I even start? Well...umm..." Roselia struggles to find something to say, emphasizing just how unprepared she was.

PSSSSSSSSH!!!

Before she can think of anything to say, Poipole heavily soaks his diaper as it quickly swells up and stains a dark tint of yellow. As he continues wetting himself, the soaking proves to be too much to handle and Poipole's diaper starts leaking from the sides and spilling its contents onto the floor.

"Oh! Did you know that Poison-types use three times the amount of diapers compared to the average Pokémon? Not only that, but they're also the type with the highest average age for being potty trained." Roselia says to the class; truthfully speaking, those statistics were completely made up, but she figured it would help keep the illusion that she was prepared for this presentation.

"That's...um...very fascinating, Roselia." Bellosom says with an expression of concern as a fairly large puddle forms on the floor. "I hate to cut your presentation short, but I'm probably violating some kind of health regulation if I don't clean up that mess and get the classroom sanitized."

"Aww, bummer, but I had so much to say." Roselia replies, feigning disappointment.

"Don't worry, you can give us a written report of your presentation next week." Bellosom says as she stands up. "Anyways, I need to get the janitor and clean this place up, so class will unfortunately be ending rather early today."

The moment she says that, all of the students excitedly burst out of the classroom and Roselia rushes her way to the bathroom, locking the door and laying Poipole on the floor once she's inside.

"Normally I'd be upset at having to clean this up, but you managed to get me out of what would have been a flop of a presentation so I guess this is a blessing in disguise." she says as she gets the needed supplies out of her backpack.

Poipole smiles and giggles while she takes off his soggy diaper and throws it away. After cleaning him up with a lot of wipes, Roselia diapers him up and heads back outside.

"Well, now I have an extra half an hour to prepare for my math test, though I'm not sure if that's gonna be of much help." she says before sitting on a bench and setting Poipole down.

While he toddles around the area, Roselia takes out her textbook and erratically flips through its pages, trying to absorb as much information as possible with the limited time she has. Unfortunately, this doesn't help her out all that much, and by the time the bell rings, her mind is flooded with a mishmash of numbers and formula.

"That...didn't really help." Roselia says before getting off the bench and picking Poipole up. "Guess it's time to take the test that I may or may not fail."

Roselia slowly makes her way to math class, tiptoeing to the door as she stalls the inevitable. After reluctantly opening the door, she spots a Decidueye staring at her with a puzzled look while the rest of the students sit at their desks.

"Roselia, why are you bringing a child into the classroom?" he asks her.

"Sorry, Mr. Decidueye, I had to use my little brother for a class project. I promise he won't bother anyone during the test." Roselia replies, though she wasn't too sure about that last part being true.

"If you insist, but he may have to be taken out of the classroom if he becomes too much of a distraction." Decidueye says as she grabs the test papers.

Roselia nods and sits people next to her desk before she sits down and gets her pencil out while Decidueye passes out the tests; once they're all handed out, the sounds of scribbling pencils fill the classroom and the test begins.

For a brief moment, Roselia feels pretty optimistic as she breezes through the first page of the test, but that optimism is quickly shattered when she sees that the next page is filled with convoluted word problems. She idly twirls her pencil while she tries to rack her mind for a solution, but such efforts end up being futile. With a groan, she skips those problems and turns to the last page only to find more word problems that are somehow even more convoluted than before.

Wanting to take her mind off of this agonizing test for a few moments, Roselia makes a cursory glance to her little brother, though she's quite surprised to see Poipole sitting completely still. However, his reasons for sitting still went beyond being stuck in a classroom with nothing else to do; he hadn't made poopies ever since last night's dinner, and now whatever laid dormant in his bowels was about to rear its ugly head as an intense pressure lingers from within.

"Mmph...mmph....mmmmmmph!" Poipole grunts and spreads his legs, preparing to unload whatever had been brewing in his bowels for those several hours.

PFFFFFFT! BLOOOOORT!! BRAAAAAAAP!! PBLAAAAARMPH!!!

His bowels let loose and he starts loudly filling his diaper as it expands and becomes rather lumpy. A nasty smell immediately fills the classroom and the students in his vicinity cringe in repulsion, though Poipole wasn't even finished yet; several more mounds of mess pile into his diaper, causing it to become much larger and lumpier as he continues pushing. Eventually, Poipole empties himself and a wide grin forms on his face, his diaper being so full that he's essentially sitting in a beanbag of his own filth.

"Oh...good heavens..." Decidueye's face is quickly drained of its color and he's immediately overwhelmed by the stench. "Test is...postponed....oh....I think I'm gonna be sick..." he storms out of the classroom and the rest of the students immediately follow suit, leaving Roselia by herself with her stinky little brother.

"Yikes, thank goodness I'm half Poison-type or I'd be running out of the classroom with the rest of them." Roselia says as she cringes and plugs her nose.

Poipole curiously looks around the classroom, wondering where everyone had suddenly gone. A few moments later, the sounds of coughing and gagging can be heard from the adjacent classroom, as Poipole's diaper was so full that its foul scent had started making its way through the rest of the school.

"Well then...uh...let's get your diaper changed." Roselia lifts Poipole up, though the weight of his diaper made things a lot harder. "Geez...so heavy." she says as she slowly makes her way out of the classroom.

While Roselia inches her way to the bathroom, she hears the sounds of students frantically storming out of their classes while that nasty odor continues to spread. After some very slow minutes, she reaches the bathroom and plops Poipole onto the floor, panting in exhaustion as she gets the changing supplies out of her backpack. However, before she can even start changing him, she's interrupted by an abrupt announcement on the intercom.

"This is your principal speaking. Due to the presence of an unidentifiable odor causing notable disruptions for both staff and students, school is cancelled for today. We will likely reconvene the next day. Thank you."

Roselia rapidly blinks for a few moments as she processes everything that just happened. A few moments later, a wide smile forms on her face in spite of the foul scent in the bathroom.

"Well...to say that I'm shocked would be an understatement." Roselia says. "You and your dirty diapers completely ruined my Sunday, but they've somehow made today into the best day ever. Not only did you save me from what would have been a horrible day for my grades, but you literally stank up the whole school and gave me the rest of the day off. I gotta say, that's impressive."

"Hehehe, tank you." Poipole happily giggles in response.

"Now then, let's just get this off of you." Roselia slowly untapes his diaper and grabs it with both hands, hoisting it up and dropping it back down as it barely fits in the trash bin.

With that settled, she wipes Poipole's bottom very thoroughly and applies lots and lots of powder before taking out a clean diaper and taping it around his waist.

"Tank you, big sis!" Poipole says with a cheerful shake of his tush.

"You're welcome, Poipole!" Roselia smiles back and picks him up as they leave the bathroom.

With nothing better to do, Roselia walks over to one of the vacant benches and sits down as she places her baby brother on her lap. It was certainly strange having the school all to herself, though she couldn't deny that the silence was quite comforting. A few moments later, Roselia looks at Poipole and realizes there was a certain phrase she never bothered saying while she had been taking care of him.

"I love you, Poipole." she says with a kiss on the cheek.

"Hehe, I wuv you too, big sis!" Poipole replies, returning with a more slobbery kiss on the cheek.

As the siblings continue to sit in silence, Roselia comes to yet another realization.

"Baby brothers certainly cause a lot of trouble, and they can sure smell pretty awful too." she says to herself as she looks at her smiling little brother once again. Though, I guess today has shown me that baby brothers aren't actually the worst after all."

When all is said and done, the chaotic weekend somehow transitions into a welcoming start of the new week; Roselia may not have been on perfect terms with her baby brother, but through an unconventional chain of events, they were now on far better terms than ever before.
