“Koniko! Bed ti-oh!”
	“Ok Mommy!” Koniko slipped by her mother before she could even finish the sentence. No need to tell her twice when it was bedtime. She zipped into the bathroom and brushed her teeth, remembering to brush in little circles just like her big brother taught her.
	She was one of the few cubs you’d find excited to go to bed. To her, there was nothing that felt as nice as a good night’s sleep. Especially when you wake up the next day refreshed and ready to have more fun. But she couldn’t go to bed without a hug from her favorite (and only) big brother. Just a quick jaunt past her own room, and she turned to burst through his open door. “Nikooooo!” She called out as she dashed in.
	Just as she arrived, Nikoli was pulling up his pajama bottoms over something that looked white and a little puffy. “Huh?!” He flinched and spun around just in time to catch his sister in his arms.
	“I saw your undies!” She giggled in his embrace.
	“Y-yeah, undies…” He nervously chuckled along.
	“Goodnight Niko.” She cooed, hugging him as tight as she could. She stood on her tiptoes to plant a kiss on his cheek.
	“Goodnight-ow! K-Koni, I c-can’t breathe!” He rasped.
	Koniko giggled before releasing the suffocating kitty and skittered off to her own room. She buried herself under the covers, making sure to get in the comfiest position before Mommy came in to tuck her in, kiss her goodnight, and turn on her ever essential nightlight. Shortly after, sleepy blinks grew to heavy eyes lids, and the little kitty was fast asleep.
*    *    *
	“Mmmm…ah…” Koniko murmured in her sleep. Her face scrunched, she shifted underneath the covers. “Oh…” A flinch, and a roll to the other side of the bed. “Hmpf…” Her legs stiffened, her thighs pressed together. Her body froze in that position for a moment, shivering against a discomfort from deep below. “Ah!” A gasp and a sudden twitch. “Mmmm...” A groan, and more shuffles from under the covers. 
Hidden beneath the sheets and nestled by Koniko’s pajamas was a golden ocean fighting to escape. She didn’t use the bathroom before bed, as per usual, and now her bursting insides were fighting to wake her up. “Hmmm…mmf.” The liquids inside her jiggled with each squirm and twist. Her bladder was tight, it sent a reverberating throb through her body that made her gasp on every other breath, yet it failed to wake the deep sleeper. 
On most other nights she would’ve long been rudely awaken by the aching pain below. With little time to as much as mewl at the stabbing pangs, she’d stumble out of bed with her paws locked between her thighs and begin the long painful hobble to the bathroom. Her need would grow with each step, her heart racing as she could feel the dam about to break. Then finally, limping through the bathroom door, thumbs already hooked under her pjs and panties, she’d tear them down and slam onto the seat before a hissing river gushed out of her. Sometimes she’d just barely clear her underwear, leaving the fur around her flower moist and a few teasing droplets on her panties. Other times she was a few critical seconds too late, and a portion of her hissing river would shower onto the floor, while her dripping panties hung between her legs like a wet tea bag. But even that near disaster was better than the alternative.
For the many nights where she failed to wake up for her body’s needs, her bed told the story better than words. An endless number of pale-yellow radii stained her mattress, and it seemed like a fresh one was imminent. “Ooooh…” Koniko moaned, she involuntarily curled up, her bladder at its absolute limit and her body desperately trying to hold back every drop. Alas, it was in vain. A heavy spurt of urine escaped her twitching slit, darkening the thin fabric of her panties. “Ah…mrrrr…” She purred, a satisfied smile growing on her face. Her body slowly started to relax out of her curled position. Her bladder was still overfilled, but that little leak gave her some tiny relief from the most urgent of the pangs.
For a while the kitten was at peace, though it didn’t take too long for her bladder to fill that space back up. “Hmmm…” Koniko tensed once more, her body subconsciously clenching against the returning pains. Her claws dug into her pillow as a whine escaped her. Her body was putting up more of a fight this time, making her shake and grind against the mattress. Her back arched, her body could feel another high pressure leak slipping through. Moments later that spurt embraced her already wet panties, spreading that dark spot further across her crotch and in between her most intimate spaces. “Mmm-ahhh, mrrrreow…” She purred as her body went limp again. The spurt went on longer than the first, completely saturating the front of her panties, leaking drizzles of moisture to her pajamas.
It seemed at this point her body had given up on waking that stubborn cat. Over the next few minutes, a constant drip leaked out as the pressure in her bladder attempted to relieve itself. As her panties were already soaked, the leak only pushed more wetness to her pajamas, and deeper into her fur. Everywhere from the start of her hip lines, tracing down her thighs to the sides of her drizzling vulva, and deep into the crevice of her rump was licked moist with urine. The warmth and pleasant release was enough to have Koniko constantly purring. She gently squirmed against the subtle tickles of thin streams flowing around her most sensitive parts. Everything down below felt like it was tingling, a strange but wonderful feeling that even prompted a soft giggle out of the sleeping cub. 
Her bladder’s patience had wore thin, as those drops rapidly picked up speed into a heavy flow. “Mmmmmuh…” Her toes curled, even her tail seizing up as her body sprung back into action. The stream hissed freely for a few seconds, blasting through the thin fabric of her undies before her body could tense up and stop the flow again. “Ah! Ooh, hah…” She shivered, panting, her thighs tight together, and her urethra winking desperately from behind the lips of her slit. While her bladder was now just slightly emptier, the sudden stop briefly evoked sharp pangs that nearly woke her up. Though before the kitty could awake to her sopping mess, her bladder begrudgingly went back to its overstressed equilibrium, leaving Koniko with a hot wetness dripping down every crease and fold of her butt and privates. She mewled and happily grinded her thighs with an audible ‘squish’ coming from under her panties. The front of her pajamas had a hearty warm yellow streak, though her mattress was unstained from tonight’s antics, something she’d consider a proud goal if she were awake. With all of these nice new feelings, she went back to a deep sleep.
Over the next hour, her bladder drip by drip refilled itself back to and past its original over stretched state. It’s warning throbs pulsated through her, her body seemed to know this was its last chance. There was no teasing this flood, any slight releases and the dam would fully break. “Mmmmm, nnnnng…” She grit her teeth. Her body rocked back and forth, a deep and almost pleasant tingling sensation arose again from her snatch as it fought not to release a drop. And from how hard she was shaking, it might just lose that fight…
“Ah!” She yipped, her eyes springing open. Before she could even recognize her room, she instinctively threw her paws to her crotch and curled inward. Her angered bladder once again sent throbbing pangs through her body, so rudely stopped on the brink of release. “Oooohhhhh…” She whined, fully conscious this time. Koniko just rolled and writhed on her bed until the pangs suddenly stopped. She gasped, feeling a sudden transition to a bloated numbness. She rolled onto her back and took a moment to breath. Jeez…what a way to wake up. Her bladder was so full it felt like it was pinning her down. She never had to go this bad before, good thing she woke up when she did. A second later and she surely would have peed herse…oh wait…she already did. 
She had already felt it when she first woke up, feeling the wet fabric of her pajamas ooze lukewarm urine over her paws as she held herself. It was unfortunately familiar enough for her to immediately know, but she just had to double check. Koniko started to lean up. “Ah! Ow, ow...” She flopped back down, her bladder was too full for movements that quick. While on her back, she slipped a paw to the inside of her pjs. She gasped at first, but then sighed. It was familiar to her, why should it be a surprise? 
It felt so humid and clammy beneath her sleepwear. It wasn’t just wet, it was soaked, and it had been soaked for a while too. The fabric of both her pajamas and her underwear were saturated, one touch elicited a one drop streak of urine down her paw finger. She flinched brushing up against the subtle bulge of her labia, its shape pushed up against the now nearly translucent fabric of her panties. Her privates still felt a little sensitive from the start and stop urges. She felt around to her backside…yep just as wet there too. She cringed as she pulled a crease of her wet panties out from her butt. She trembled when that unlogged more cool droplets that ran down her sensitive parts. With her clothes confirmed to be wet, she used her other paw to survey the damage of her bed. She rolled over as gently as her bladder allowed and felt the sheets. It was a little damp under her rump, though not as much of a disaster as it was inside her pjs. She bet it barely even left a spot, no doubt it would dry by morning.
Koniko sighed, it was annoying that she had just barely had an accident…again, but it could’ve been much worse. She doubted that would mean much to her parents though, they’d see and smell the stains left on her pajamas and stick her right back in diapers. That thought made her frown, she really liked her big girl panties. They came in all her favorite colors, and they looked so pretty on her, unlike those ugly bulky cloth diapers that only came in white. They also didn’t feel anywhere near as nice as her panties either. Even right now, while all moist and steamy…the fabric felt so comforting to touch.
She felt back over the spots in her pjs that she already inspected, feeling her paws warm up the cooling liquids, getting that satisfying squish when she pressed and squeezed here and there. Getting that flinch, that involuntary twitch, when she traced the shape of her cunny in that soaked through fabric. Mmmmm…really comforting to touch. In fact, she couldn’t stop touching, for some reason it just felt so, so, nice, so tickly in its current wet state. The very state that’s gonna get them taken away. Mmfh, well if she’s gonna lose her big girl panties, she might as well enjoy them while she still can. 
“Ah!” Then suddenly, it came roaring back. That strong throbbing need that woke her up. She couldn’t react fast enough, a hot jet of pee sprayed the insides of her underwear again, pushing more liquid out into her pajamas. She sent her paws inside her pjs, holding herself directly on her panties. She whined as she roughly scooted herself to the edge of the bed, tears welling in her eyes. It was unfair that she already peed herself and still had to go this bad. All of the pain of making it to the potty, and still destined to be diapered. 
As she sat on the edge of her bed, desperately kicking out and bouncing, Koniko felt the stray temptation to just let it all out, right then and there. She grit her teeth as she considered, her knees grinding together. Something deep down really wanted her to let go, to just let it gush out into the welcoming embrace of her bed. She’d feel the soft mattress beneath her warm into a spongy cushion as it just kept flowing, and that heavenly relief she’d feel…the thought of it made her tingle down there. She let out a sad groan, trying to shake the thought from her head. Of course she couldn’t do that, her parents would keep her diapered for the rest of her life if she did. Big girls aren’t supposed to wet the bed, never mind like it. She gave the dry bed a longing squeeze as she fully committed herself to going to the bathroom. 
She bounced up to her feet and shuffled over to the door. Koniko brought one dripping paw out from her pajama bottoms to twist the knob and froze. She found herself staring down the dark, all-encompassing abyss of the hallway. She gripped the door frame, her legs crossed, squirming in place. She pouted at the sea of black before her. She hated the dark so much, who knows what’s out there just waiting to grab her and gobble her up! Hnnnnng, a-ah! She gasped and hopped in place. A sudden sharp urge whipped right through her, a brief leak refreshing the wet the crotch of her pjs. Ooh, this couldn’t wait. She swallowed back a sob, and dared to take one small shaky step, er, more of a limp out of the door. And, it’s been about 2 seconds and so far nothing’s tried to eat her yet. M-maybe she’s safe?
	Koniko continued her arduous journey through the hallway one painful limp at a time, each one making her breath shudder. Her bladder sent out angry searing spasms in retaliation for being left overfilled and jostled about on each limp. She could only whine and mewl under her breath as an apology. She still had a long way to go as she was only passing in front of Niko’s room, just halfway to the stairs. She considered knocking on his door. She could really use some help from her brave big brother to fend off the monsters on the way to the bathroom. Or even just a hug to make her feel better. But a feeling of guilt hit her at the thought. She shouldn’t wake up Niko from a peaceful night’s sleep and get him potentially maimed by a ghost just because she’s a scaredy cat. And at this rate, she might not even be able to hold it long enough to get out of his room…he definitely wouldn’t like that.
	She paused to press down and squirm. Bye Niko, she said sadly in her head. She lifted her foot to start another limp but flinched and tripped forward. Even that mild lift was enough to tempt her bladder. Instead, she resigned to take little shuffles, just barely dragging her feet along the carpet. She sniffled and let out a few hushed sobs. With her progress slowed even further and not even as much as a comforting hug, she was thoroughly disheartened. The jet-black darkness didn’t help her spirts either. She swore she could feel the thin fingers of some sharp tooth creature just brushing against her back. The liquids inside her shivered with every shuddering fearful breath. She could feel it painfully teasing her little cunny with relief like drops hanging on a faucet. Ah, she sobbed, tears going down her chin. She needed someone to save her. She needed her big brother, she needed her parents, she needed a…light switch! Right there on the wall was her true savior!
With a single flip, her environment went from evil dark cavern back to a bright and mundane hallway. A smile appeared on her face for the first time in what felt like forever. It gave her hope to know she was safe and sound. She shuffled on with more confidence. She can do this! She can make it! Sure, her pants were already wet, but only a big girl would so bravely keep going-oh…the stairs. Koniko finally reached the end of the hall, and probably her biggest challenge of the night. She stood before the first step, her hips swaying. The first floor landing suddenly looked like the base of a steep mountain…and she was about to add her own waterfall. 
	She glanced back at Niko’s door, her lip quivering. She felt another urge to call for her hero. He’d know what to, he could help her make it to the potty…right? No…he couldn’t work magic. He’d wake up just in time to watch her burst, and maybe give her a hug when she started to bawl like a baby. No, she has to be a big girl. For Niko at least, since it was too late for her parents. She lifted her foot to step down, but just like earlier, flinched feeling her internal ocean threaten to drop. No, she’ll have to hop each step. She sniffled her tears back and braced herself…
“Mmfh!” She grunted. Upon landing on the next step, stabbing pains emanated from her bladder and echoed throughout her body. Immediately, streams flowed from between her thighs to relieve it. She held on to the handrail to keep from falling completely. She shoved her paw into her crotch, bending, trying to put as much weight on it as possible. Her rogue release came to a hurting halt, though not before leaving her panties steaming with a fresh hot soaking. 
She stood there for a while, letting her mewling sobs rack through her while the blistering aches settled down. She wasn’t gonna make it down those stairs…there’s no way. She’d simply explode. But…if she stood here any longer, she’d still explode. Between a rock, and a wet place. She bounced in place, looking around for her brother, or maybe her parents to tell her how to get out of this conundrum, but was only met with the sounds of her own rapid breathing. She was alone. She had to be the one to decide this time. It felt kind of scary, but also empowering. Big girls make their own decisions after all, and she decided that if she was gonna explode, she might as well try to make it to the potty. That would be the big girl thing to do…right?
She took a deep breath, made sure her knees were bent enough, and went for her next hop. “Aah!” And the next one… “Ooh…hmph…owwie…hah…” Hop by hop, each one prompted a spasm from her frustrated bladder, and another stream down her legs. Her wet footpaw-pads squeaked on the hard wood with every landing. It was a disaster waiting to happen. Just 3 steps from the bottom she slipped on her own urine and fell down each step, landing roughly on her poor pink tush. 
A hissing sound filled the air as suddenly her privates and backside were embraced by a rushing heat. Her eyes went wide as a moan escaped her. Oh gosh, after all that holding and pain, this full stream felt so, so, good. But it’s getting on the carpet! Koniko whipped both paws between her thighs, were they impacted with a shwish. Hot fast running urine gushed through her pajamas and between her fingers. She grunted and strained as hard as she could to stop it once more, it hurt to even think about stopping. The transition from that brief blissful relief to a searing pressure left her squirming on the floor. 
She huffed out, trying not to wail. She had completely soaked through the carpet under her butt, and a puddle had spread to the bare wood floor…her parents really aren’t gonna like that. She was so close! The bathroom was just around the corner, she could even crawl to it in a matter of seconds! But she couldn’t move. Her crumpled pretzel-legged position on the floor was the only remaining barrier keeping her bladder at bay. She looked at the open bathroom door with a bitter pout. What a stupid, dumb, mean night, she thought to herself as she sobbed. 
Though, as she sat there squirming, her paws essentially massaging her slit beneath the fabric to keep it from leaking, Koniko couldn’t help but notice that tingle again. Mmf, the squirms, combined with all the pressure on her crotch, it felt really good to touch down there. And her full bladder, it was so tight, it made her whole body feel so sensitive. She rubbed all over her soaking wet crotch, absolutely steaming and stinking of cat piss. She traced over her taught bladder in her lower belly, the intense sensation made her leg kick out, she grit her teeth to keep from giving in and letting it flow just yet. 
She blinked through tears to look at the bathroom. She wasn’t gonna make it, not that it would make a difference with the mess she made. But with the fire growing between her loins, she didn’t really mind that much anymore. She was gonna get in trouble anyway, so for these last few fleeting moments of control, she wanted to enjoy it. 
Her sobs started to turn into breathy pants. She couldn’t stop touching and rubbing herself as her urge grew. With every new pain came new pleasure, the burning tightness hurt so good with the explosion of tingles from the pulsating walls of her pussy. She shoved a wet warm paw up her shirt, staining her clean pink fur underneath a sloppy pale yellow. “Ah…mrreow, mmm.” She moaned using that wet paw to trace each budding nipple. She used her other paw to bury deep in her panties, it was so hot, so wet, and a little sticky. “Mmmm, meow, ah…” She closed her eyes and shuddered while gently fingering the outsides of her tender flaps. She panted through her open mouth, the sensations were so strong she could almost them it begging her to go in. What was this feeling? Why was her heart beating so fast? She’s never felt these urges before. A hungry need possessed her, and guided her fingers into that greedy hot slit. “Ah! Aaah!” She flinched, every gentle touch of her fingers against her soft sensitive insides overwhelmed the little kitten, it was almost too much. She squeezed her thighs together as tight as she could. Ooh, that one brought her real close to peeing! 
Every part of her trembled and clenched, she couldn’t stay still. She could feel it, she could feel her limit approaching fast. The pressure behind her cunny was becoming disorienting, she was about to burst. But she didn’t care. She was only disappointed she didn’t have more time to explore herself while this feeling lasted, oh well. She smiled as she removed her sticky paw from her panties, the only thing holding her bladder back was shear will power. “Hmph!” She clenched, her face flushed, using every muscle in her body to try to hold back that flow a little bit longer. Her heart raced as that heavy pressure got higher and higher, her whole body shaking, eyes scrunched closed, the tingles in her pussy reaching a crescendo, she could scream. Suddenly she froze as her bladder finally burst. Time seemed to stop. For a moment, she felt numb. It was like she was floating as her body glitched. And then, it all came back crashing down.  
“Haaaaaahhhhhh…” She went limp against the staircase behind. A hot river shot out of her harder than she’s ever peed before, so desperate to blast out of her. Wave after wave of relief just kept washing over. All of that pain and throbbing became more of a distant memory with every passing second. The puddle around her quickly grew from that soaked carpet, piss splashed and flowed through her pajamas as if they weren’t even there. Pee even soaked upwards through the fabric and stained her tummy fur up to her bellybutton. She smiled and gave weak movements with the little strength left in her body. It was so satisfying to feel her flow change course and send its powerful stream over different parts of her legs and thighs with every move, as well as feeling the ruined carpet squish under her. “Mmmm, mew…” The tingly feelings in her slit had slowly tapered off, giving a nice gentle transition into that subtle pleasure of urine flowing through and over all of her most sensitive parts. Koniko laid her head back on the step and popped her thumb in her mouth. She basked in that empty feeling as her stream finally started to slow. She could feel the mini trickles around her gradually getting thinner until she was left with a refreshing drip from her cunny. 
Koniko let out a sigh that was half meow and half yawn. That felt incredible and just about put her to sleep. She didn’t know what rage awaited her in the morning when her parents find the flood she left behind, but at the moment, she didn’t care. She just wanted to go back to bed while this euphoria still lasted. 
She slowly stood back up to her feet, the urine that puddled on top of her oversaturated bedwear rained down on the also oversoaked carpet. She stretched with a smile feeling her wet clothes shifting along her body. She patted the darkened spots around her crotch once more and ventured to stick a paw back her pants. Mmmm, still nice and steamy. If only it could last forever.
Koniko made her way back up the steps, refreshing the droplets from her initial descent. The entire hallway would stink of her essence by tomorrow morning. She felt kind of proud of that fact, everyone would know about her accident, and the memory of all that pleasure would last even longer…oh? Her ear twitched at the sound of a knob twisting. She jumped upon seeing Nikoli’s door open. All the excitement and pleasure from just moments ago suddenly disappeared. She didn’t think trouble would come this quick! Her mind raced thinking of an excuse or a hiding place, or just how much to beg. Though, she only managed to stand frozen while her yawning brother approached.
“Koni?” Nikoli rubbed his eyes. “What are you…” He sniffed the air, something smelled…familiar. His sleepy questioning squint slowly grew into a wide-eyed stare. 
Koniko smiled back shyly with her dripping paws at her chin, trying her best to look cute and innocent. “H-hi Niko.”
“Did, did you…” He looked her up and down. A slight blush rose on his face. “D-did you have an accident?”
She hung her head. “Yes…” It was too obvious to lie at this point. “I really had to go potty when I woke up, but it was really dark and scary and…I didn’t make it.” Huh…Koniko was used to feeling ashamed or really sad upon having to admit her accidents, but this time was…easy? “P-please don’t tell Mommy and Daddy.”
“Aw Koni…” Nikoli moved in to embrace his dripping sister. “Don’t worry, I’ll keep it a secret.” Though, the wet ammonia scented floors would probably give it away. “Why didn’t you ask me to go with you?”
“I thought if I woke you up, or had an accident in your room, y-you’d be mad at me…” That part didn’t feel as easy. She hated upsetting her big brother more than wet pants.
“I’ll wouldn’t be mad at you, I don’t like the dark either!”
“You wouldn’t be mad even if I…went pee-pee in your room?”
“No, even big kids have accidents.” He ended with a shy chuckle.
She giggled. “Ok, then next time I’ll just go potty in your room!”
“Sure!” Niko answered a lot more excited than she expected, it made her giggle even more at that silly thought.
“You’re the best big brother ever.” She said hugging him again, this time extra tight.
“Ow! Koni!” Niko choked out a few chuckles while trying to pry her limbs off.
“Goodnight Niko.” She cooed for the second time that night.
“Wait, you’re gonna go back bed?” She nodded, a sweet content smile on her face. “But you’re all wet.”
“It’s Ok!”
“It…is?”
“Yeah, because…” She felt a naughty jolt of excitement in her. “I like it.” She said with a sneaky smile, the kind of smile that only comes with mischievous acts.
“Oh…” Niko blinked, his own skittish smile starting to form.
Koniko stuck a paw into her wet pajama bottoms. A little bit drier, but still damp and humid. “It feels really nice and warm, like a wet hug!”
“D-did it feel good when you had the accident too?”
“Yeah, yeah!” She hopped with excitement. Confessing her misdeeds felt so fun. “It felt really really good! I didn’t have to go potty anymore, and my pee-pee felt all tickly.” She did a little twist in place, trying to reawaken that flame between her thighs. 
“O-oh.” Niko mirrored her red. He looked over her wet pajamas with an excited shiver. “U-um…Koni, can I…f-feel it?”
“Huh?” She paused, tilting her head.
Nikoli pointed at her crotch. “C-can I feel how w-wet it is?”
“Um, Ok!” Koniko felt some shyness wash over. No one else has ever touched her down there except her parents during bath time…is this Ok? Yet, her heart raced as Niko’s paw approached. She gasped when he made contact. Almost immediately she felt that tingle come back.
“Woah…” Niko whispered. The liquid staining her pajamas, that just minutes ago was still inside her, held its warmth and fresh scent. He gently pat between her legs, droplets flowed through and dripped off his paw fingers. 
“Mmmfh…” Koniko’s face contorted feeling those tingles ebb and flow with each pat. It was hard not to squirm at those sensations. 
“Sorry!” Niko flinched at her sounds and quickly pulled his paw away.
“No!” Koniko grabbed his arm and guided his paw back. She nodded and smiled when he met her eyes.
“Oh, um, O-Ok…” Niko was confused, but he certainly wasn’t gonna say no. He cupped his paw around her crotch. He blushed feeling her shape, the subtle impression of her lips under layers of wet fabric, and her soft perineum leading to the beginnings of her rump. He’s seen his sister naked before, but he’s never actually felt her parts, it was like he was exploring a new person. Her little moans and shivers made him nervous but more eager to keep going. He gently squeezed, a steady small drizzle of pee escaped her pajamas. “You went a lot…” He barely mumbled, just mesmerized by the lukewarm liquids soaking his paw. 
Koniko huffed out on every other breath. Mmm, she could feel her inner walls throbbing with need again. Niko’s paw explored a little bit upwards, groping her soaked pubic mound just below her waistband. She let out a small gasp when he slipped his paw inside her pajama pants. Niko paused and locked unsure eyes with her, was that a ‘good’ sound? She smiled and nodded. He continued his exploration, rubbing the along the front of her panties, feeling the bulges from her genitals much more prominently. “Mmmm, mrreow…” She mewled as he traced along her parts. She couldn’t stand still, and her thighs constantly squeezed and brushed against his wrist.
Niko took those as more ‘good’ sounds. He didn’t know what he was doing, but clearly it was the right thing. The wetness lining her panties along her cunny felt much warmer and sticky than it did from the outside. It had a much stronger and fresher smell too. Feeling these fresher drops ooze from the fabric of her clothes and her wet fur also made him feel antsy. His own erect parts twitched and brushed against the insides of his bottom wear. He squirmed against the odd feeling, giving his bits a tease of the attention they desired. Though it was becoming clear to him that he was squirming for something else too. 
Suddenly he flinched and groaned. He brough his paw out of Koniko’s pjs and grabbed his own crotch. “Niko?” She was both concerned and disappointed by this sudden stop.
“Hey Koni…you wanna see mine?”
“Um…yeah!” Koniko edged in closer, not sure what she was gonna see, but she was hot bothered and curious. Nikoli lowered the waistband of his pajama bottoms, revealing…padding?! She gasped. “You wear diapers?!”
“Only at night…and s-sometimes during the day too.” He shyly shuffled in place.
“I thought big kids don’t wear those.”
“S-some of us do! Diapers or accidents don’t mean you’re not a big kid.” 
“They don’t?” That made Koniko think. It’s not like she was different person every time her parents put her in diapers, but it certainly felt different. 
“And with diapers you can do this!”
“Huh?” Niko’s little shuffles stopped, and he took a wide stance. Koniko was left tilting her head again until her ears caught the sound of hissing. She looked up at Niko, who had a goofy relaxed smile as that tension was released.
“I really had to pee too.”
“Oh…” Koniko giggled. Her ‘big’ brother was having an accident too! “It sounds like a lot.” She eagerly eyed his crotch as the padding slowly expanded and grew a pale yellow.
The hissing started to slow. “It was.” He sighed. “But probably not as much as you. You wanna feel it?” Niko edged his crotch towards her, excited to share his soggy pants too.
“Yeah!” Koniko eagerly grabbed a paw full of the yellowed diaper. “Ooh! It’s squishy!” She nearly squealed. She squished and squeezed the soft juicy padding, she never noticed how satisfying it was when she wore them, way more fun than plain panties! They didn’t even leak when she squished them either, perfect bedwetting protection.
“Ah! Be gentle!” Niko flinched.
“Oops!” She assumed that less squishy part must’ve been his part. If it was, it felt stiffer than she imagined it would…kind of like a hotdog. A warm, stiff, twitchy hotdog, and not that bouncy rubbery little dingy she sometimes saw peeks of. She giggled when Niko started making similar huffs and trembles at her softer touches. He must’ve gotten those tingles too. “Niko, if you can make it to the potty, why does Mommy and Daddy make you wear diapers?”
“S-sometimes,” He sputtered in between a huff. “I-I don’t make it, but they don’t make me wear them anymore.”
“They don’t?!” Her eyes widened at what that implied.
“Ow, ow! Koni!” She also may have squeezed down a bit hard in her shock.
“Sorry!” She released his diapered anatomy and giggled watching him give soothing rubs to crotch. Boys are so funny and squishy. “But then…why do you where them?”
“I like them! They feel really soft, and if I can’t make it or don’t wanna wake up, I don’t even have to go to the potty!” 
For a moment Koniko was too shocked to speak. The biggest, bravest kid she knows likes to wear diapers?! Well come to think of it, those nights where she had to wear one felt extra cozy, and they did save her from some wet beds. “But you don’t feel like a baby when you’re wearing it?”
“Not anymore. I always try to make it to the potty…uh, except that last time, but that doesn’t count! I’m still the same big boy I was when I wore undies, just now I’m more comfy!”
“So even if I have to wear diapers tomorrow…I won’t be a baby?”
“Nope!”
“Not even if I use them?” She asked with a bit of a mischievous rise in her voice.
“Still a big girl. But you’ll still have to be my little sister, hehe.”
“I can be that!” Koniko said with a little joyful bounce. Her woes of ‘punishment’ disappeared. In fact, she looked forward to a diapered future, comfy when dry and really nice when wet, though not that she would willingly let them get wet. She is a big girl after all. She hugged Niko back, though was more merciful this time. Too tired for violence. “Goodnight Niko.”
“Goodnight Ko-” Before he could finish, Koniko while on her tiptoes, pulled his face close to press her lips onto his. He was too flustered to know what to do, so he just let her take the lead. She rubbed their snouts together and darted her tongue out, brushing against his mouth fur. Niko took it as a sign to open his mouth and do the same with his tongue. Though he was immediately met with the wet warm slimy feeling of his sister’s tongue and the taste of her breath. He broke away to cough. This type of kiss was an acquired taste it seems. “Koni?!” He gasped for air. “What was that?!”
“Hehehe…I saw in a movie that grown-ups kiss like that after touching their parts!”
“I don’t think we did it right…” Niko wiped the spit off his mouth with a rather glum expression. Koniko skittered off towards her room in a mischievous giggle fit. “Koni, wait! Do you wanna sleep in my bed?”
She spun around. “Really?!” Spending the night all cuddled up with her big brother would be the best. Plus, with the two of them, those night monsters would stand no chance! “Even though I’m all wet?”
“It’s Ok,” Niko replied with a shade of red dusting his cheeks. “I don’t mind being wet.” In fact he might’ve been just hoping for it.
“Oh, Ok!” Koniko eagerly rushed into his room. She got under the covers, letting them sink around her legs and gain some of the moisture from her pjs. She could already feel those sleepy blinks coming back. When Niko got in next to her, she found just enough energy to forcefully align herself in his embrace, albeit with some brief giddy tussling. In their final position, she could feel some of the lasting warmth from his diaper against her backside and feel the cooled liquid from her pajamas soaking into his. Ah, everything felt just perfect. When she woke up, she’d be refreshed and ready to take her ‘punishment’ in stride.
