The room was dark and heavy, illuminated only by a lamp on the desk, which had been pointed down and towards the wall so as to not flood the room with its otherwise brilliance. Across from the desk, a stout figure kneeled on the bed, panting heavily, gasping for breath through the humid air, each inhale smothered and fetid, burning her nostrils and catching in her throat. The musk of urine and acrid bitterness of ammonia lingered unmistakably, though not unbearably. Previous attempts to hide the obvious had only thickened the air further, adding a new sickening sweetness that tipped the stench into unlivable territory. And so the room lay heavy with the stench of piss and diapers.

Her loins burned deeply, her nerves convulsing almost beyond control. The intensity of her sensation bordered on pain, and yet her pleasure was unmistakable. Her gaping maw was silent, save for the occasional squeak or moan. The bat's large ears twitched in sync with the clenching of her eyelids as she bobbed up and down, her knees struggling, shaking so violently they gave out every few bounces.

Rhou had been busy scratching a new itch that had formed in her mind after surfing for porn one night. Though her initial reaction had been one of horror, sending shivers of imagined pain down her spine, something deep inside her was curious. She was already deeply familiar with similar sensations, she reasoned with herself. She loved the pressure in her bladder, at least while she was awake and able to hold it. She loved even more the tingling that accompanied the intense relief when she finally released, the orgasmic sensitivity when she teased the opening of her urethra as she peed, plugging herself on-and-off while she rubbed her clit. Surely, it would burn with that same intensity she felt while peeing against her finger with a full bladder.

Her mind made up, it had taken only a matter of clicks before a new box of toys was on its way. But she couldn't wait that long; she needed some form of release right there and then. That night, sitting in her chair at her desk, her diaper undone beneath her, she had put on some more porn, grabbed a pen, and slathered it in lube. In a moment of judgement clouded by arousal, she had with shaky hands taken the virginity of her third hole, inserting far too quickly and deeply with the tip of the pen, her other paw's fingertips pressing her clit. In an instant, her mind had broken, unable to process the multitude of nerves firing in her loins, made only worse by her instinctive convulsion. In a cry of pain and pleasure, she had lost control of her body, her bladder releasing full force, the pen causing her stream to hiss violently and spatter across her thighs, diaper, and even onto the carpet below. Unable to release her grip, the pen had swirled violently within her, causing her to hiss through her bared fangs as blood trickled from her lip.

It was over in an instant, though it had felt like an eternity. A lapse in electric tension allowed her to dislodge the pen from her urethra, tossing it onto the carpet below along with the rest of her stream. Leaning back in her chair, her legs spread, she had simply allowed her body to do as it pleased, gritting her teeth through the now stinging stream that hissed as it arched over her diaper and into the unprotected carpet below. Though the pain was new and incredible, tears streaming down her face, a deep pleasure overtook her, torturing her with an orgasm that lasted through the bloody deluge.

The cleanup for her hasty experiment had been difficult. Exhausted and unable to see or even care about the damage, she had simply turned, rolled out of her chair, and laid on her floor, passing out with her diaper draped over her leg between her knees. Once awake, she became aware of the lingering pain, as well as the matted fur on her thigh where her nocturnal release had been unprotected. There lay not one, but two orange-yellow stains on her carpet, and some staining even on the wall behind her desk. Though it had missed the most of her stream, her diaper, having been beneath her, looked like it had been worn on one of the later days of her period, stained only faintly but visible nonetheless. The pen lay discarded in the larger, darker stain beneath her desk. Though her bladder was large and normally only weak at night, she had cringed through uncontrollable and particularly intense voids for the entire next week.

Though it had been nearly a month since that first time, and her package had long since arrived, she was finally ready. She was horny, but not so much as to lose control like last time. Her urethra was now fully recovered, and her usual daytime bladder control had resumed, though, she mused, this might just change that.

She waited until deep in the night. Her brother Hart was out with the boys, sleeping over at Timmy's house. Her father, his bedroom being across the house, was no concern of hers, though he rarely disturbed her anyway. Her desperation had slowly grown as she lay in bed, wearing only her diaper. She struggled, clenching her thighs and rocking gently, teasing herself as her diaper crinkled around her waist. She wanted so badly to be her usual naughty self, to let herself go on purpose, at least once before falling asleep and giving up control. She usually got herself off on wetting her bed, whether or not her padding succeeded in protecting the sheets. But tonight, she would push herself even harder. When the time was right, she rolled out of bed, carefully. Navigating only by muscle memory and the dim light of the streetlight outside through her paper shades, she opened up a drawer beneath her bed, retrieving her package and crossing the room, her diaper giving away any stealth she had were there any unseen observers.

Flicking on the light at her desk, she had gasped in shock as its brilliance blinded her; the bulb, though not pointed directly at her, was nevertheless exposed, the gleaming filament leaving a violet floater in her vision. She swiftly turned the head of the lamp to face the corner where her desk met the wall, casting a dim yet moody glow across the room. Her night-adjusted eyes helped her to see in greater detail, though there was still enough light to allow her to experiment properly. Now, setting the box on the table, she tore the tape sealing her package with a single claw before slowly lifting the lid.

Inside was a simple zippered case covered in faux leather. Lifting the case in both paws, she set the box aside, sitting down as she slowly unzipped the case. Unfolding it revealed a number of steel rods of varying diameter, each held in place by a single elastic band. Each had a small bulb on one end to prevent inserting too deep. Her curiosity and arousal slowly growing, she allowed one paw to drift beneath her diaper, reminded instantly of her desperation as her loins burned anew with the need to release. Her other paw slowly retrieved the smallest sound from the case; she was more careful this time, and wanted to start slow. The chrome finish glimmered in the dim light, the metal cool in her hand. She wondered how the chill would feel as it first entered her. Her breath now grew heavy and desperate, her arousal and need to pee driving her mind to the brink of pure instinct.

Putting the sound down momentarily, she tore off the tapes on her diaper, leaning back slightly and slipping her padding off of her hips so that it lay beneath her, with the front panel of the diaper hanging over the edge of the chair. She was dripping wet, her honeyed arousal coating her fingertips as she ran them over her folds. Her loins begging for release, she whimpered as she retrieved her lube from a drawer in her desk and coated the sound. Scooting back in her chair a bit more to allow her padding more room, she spread her legs over the arms of her chair, pulling a standing mirror on her desk toward the edge so she could see a bit better.

With bated breath, she lowered the sound to her folds, the metal still dripping with an excess of lubricant that she suspected she would need. Her paws trembled slightly, this time from her anticipation, as she gently stroked her labia with the tip of the sound, trying to part them to let her find her opening. She let out a whimper as she felt the sting of the cold steel, followed by a deep warmth as a drop of her urine leaked down her folds, the rest of her stream threatening to follow.

Inserting the sound was far easier at first than she had first imagined; with its thin, rounded tip and a more careful touch, the toy slid easily into her urethra, another trickle of warm urine dripping down her loin fur into the diaper beneath her. It felt good to slide in and out, slowly; it was cold, but warmed up quickly. It was smooth, leaving her with a sensation not of pain, but of fullness, intensity, and the familiar tickle of relief. Rhou moaned once again, softly, as her other paw reached for her clit as she slowly took herself, realizing but not caring that she was still leaking. Though the sound plugged her opening, its diameter was far too small to completely stop her flow; her body was used to much larger, more forceful streams, and this small obstruction proved only to prevent her body from maintaining any urinary continence. Pressing slower, deeper, rocking her hips to help guide her new toy, she felt the sound press against her g-spot, nearly all the way into her bladder. It felt heavenly, yet she wanted more. She knew she could take more. And so, she slipped the sound out of her peehole with surprising ease, clenching as she managed to stop her stream after only a brief spurt as she removed the metal rod.

The pile of damp sounds began to accumulate on her desk as she continued playing with herself, making sure only to edge herself as the sounds filling her continued to grow larger and larger. Though the sounds became more and more effective at plugging her opening, she continued to leak as she rode each, spurting heavily with every removal. The padding beneath her grew more and more damp as she eventually became unable to hold herself all the way, a slow but steady trickle flowing down her loins. She was surprised by how much she could take before feeling any pressure; unlike her anal sessions, her peehole seemed to readily accept her toys. Though she had been horny the entire session, curiosity and first-time anxiety had until now kept her from losing control, though her edging now left her craving climax, perhaps several. As her mind wandered between naughty ideas, she continued to play with the sounding kit until she reached one that made her feel deeply full. She had to relax her entire body and resist holding her breath now to not climax, the sound nearly all the way inside her. It was already the third largest sound in the kit; though useful for warm-ups, she suspected she may need a new set of toys soon. But for tonight, this...this was the one.

Rhou scooted herself forward in her chair, grabbing her diaper's front and back in each paw, lifting it beneath her as she slowly rose from her chair to adjust. A swift tingle arose in her as the sound slipped, accompanied by a trickle of warm urine, both stopped only by the damp lining of her diaper. Sitting back down, she whimpered as the sound slid back into her. Fastening her diaper as quickly as her trembling hands would allow, Rhou rose from her chair, crossing the room with a heavy waddle. Climbing gingerly up onto her bed, she then retrieved her favorite toy from the nightstand drawer before grabbing her pillow and shoving it between her legs. Slipping the wand between the pillow and her diaper, she clenched in anticipation as she pressed its on button.

Her orgasm was swift in coming and threefold: her clit pulsed against the powerful vibrator, her hips rocking instinctively against the bulb with such force that her diaper's damp padding was forced to the sides, leaving only the thin plastic shell and inner lining between her burning nerves and the wand which delivered them such pleasure. The vibrator also caused the sound to resonate deep within her; such movement, no matter how subtle, created a deep tingling that made her scream with pleasure as her bladder strained against its obstruction, a steady, noisy trickle forcing its way around the sound and pooling beneath her, mixing with her slick cum and burning her clit with its warmth as it pooled before soaking into her padding. Finally, her rocking allowed the sound to slip in and out of her, if only an inch or two, and yet in her pleasure she finally penetrated her bladder. The pressure in her g-spot and bladder alike caused her belly to ache deeply each time she pressed the sound into her, her trickling stream begging to be allowed to release in full. This ache, accompanied by the fiery pleasure in her clit, left her whimpering, panting, gasping for breath in the fetid air of her bedroom with each impulsive rock.

Her climax felt as though it would never end; she continued in her state of tortured pleasure for several minutes, constantly on the brink of a new climax before the triple stimulation pushed her right off the edge again. When she finally managed to gain enough control to think clearly, she turned the vibrator off, throwing herself back against the headboard, sitting up. Rhou clawed desperately at her diaper, pulling the tapes hard and tearing holes in the plastic as she pulled the diaper away from her body. Grasping the sound in one paw, she rubbed her clit with her other as she fucked her itching peehole hard, slipping the toy nearly all the way in and out swiftly, stopping every few thrusts to pull it out, let out a short, yet violent arc of piss, before continuing her hedonistic assault. Finally, her fur damp from sweat and arousal, her final climax arose within her, the one with which she would allow herself to release.

She held the toy inside her as long as she could, shoving it all the way in until she felt the pop as it entered her bladder right when she came. Letting out an uncontrollable scream of pleasure, her eyes clamped shut, and she desperately pulled the sound out of herself as her back arched, her entire body convulsing as her bladder released. With a sputtering roar, her piss surged from her, pooling quickly in her diaper beneath her and leaking easily out of the leg bands within a second, coming far too quickly to be absorbed by her diaper or the bed beneath her. In a moment of orgasmic pleasure and bliss, she closed her eyes, continuing to press against her clit as she felt herself slide down into her bed, her back growing warm and wet. The diaper only slid so far beneath her; as she drifted onto her back, her piss growing into a high arc, she could feel the sodden padding squish against her back, before bursting on one side beneath her weight. Her deluge hissed noisily, pattering against the bedsheets before the sound grew deeper, wetter, and then higher again as it pooled, splashing against itself. Though her eyes remained closed, her clit tingled in pleasure as she felt a new wave of warmth crawl up her buttocks and down to her heels. Pressing hard, she heard her stream patter against the bed frame, then nearly disappear at first as it trailed off the edge of the bed, pattering against the carpet. She pressed and rubbed, teasing her peehole as she had before with her fingertip, this time able to dig her digit into her hole, causing a splash across her thighs and even up onto her tummy before puling back out to resume her climactic slash.

She continued to press, moaning softly as she desperately listened to the sound of the carpet growing soggy, arching her hips a little more before hearing the satisfactory patter of her stream splashing against the wall. She sank into her puddle as she aimed herself, crushing her diaper beneath her into a nearly liquid pulp, not intending on letting up. But alas, the strain of hitting the wall proved too difficult in her state. Pouting playfully, now coming down from her orgasm, but still far from empty, she continued to touch herself, unable to stop herself from leaking, though at least able to stop her spray for long enough to roll over, her diaper's shell sticking to her back before slipping off with a wet splat, splashing her with warm urine and leaving clumps of slimy crystals in her fur. On shaking hands and knees, her ankles and wrists submerged in a pool on her bed, she weakly pawwed at the edge of her sheets, pulling them out of their neatly tucked position so she could crawl beneath. As she did so, the pool of urine ran across the saturated blanket, splashing noisily against the wall before cascading down into the carpet below. Her toys too rolled off the bed, in the opposite direction onto the floor in the middle of her room. 

The comforter was heavy, piss still dripping heavily through the padded fabric onto the pool already formed in her sheets. Smiling to herself, Rhou climbed all the way into bed, letting the heavy fabric squeeze its damp contents into her fur, her hair clinging now to her body. Still panting, laying face-down against her pillow, its lower half wet and musky against her snout but the top somehow still dry, she took in the deep scent and relaxed. The relief was heavenly; without orgasm or obstruction, she simply savored the warm tingle of post-urethral play as she relaxed her bladder once more, feeling herself drift off into an exhausted sleep as the pool of warmth climbed her body. She knew she couldn't hold it at night anyway; this would keep going until she was empty. Perhaps tomorrow she would rub herself off as she inspected the incredible damage she had done, but for now, the sensations of wetting and sleeping alone were orgasmic enough for the exhausted bat. She was lulled to sleep by the soothing sounds of waterfalls; the steady dripping of pee from her blankets and through her ruined mattress onto the sodden carpet below soon became replaced by a symphony of streams as the new puddle in her bed overflowed, crashing down in a growing pool of gold as she slowly flooded her carpet.
