It was not until several days after her wedgie escapade that Chelse was finally able to have enough time to run to the store and back without anyone at home that could catch her. Her only hope now was that she wouldn't be bumped into in public. It was finally time for her to try out wearing a diaper for the first time; her interest had been piqued after seeing Rhou's own excitement during the sleepover about a week ago now.
	She had told no one, not even Cath; just in case she didn't end up liking them. Without a car, she would be forced to go on foot; she had chosen a weekday to ensure fewer people would be out. She had no idea why the idea embarrassed her so much, but she shook as she donned her shoes, double-checking that she had her card on her to be able to pay quickly. She had the route all thought out: the pharmacy happened to be the nearest store, and was perhaps a little less than a mile away. It wouldn't take her long to jog over, and shouldn't take long to run back. In-and-out, before anyone noticed. She had allotted plenty of time, yet the idea of her family coming home that day at all made her feel the pressure of every second, a lump in her throat.
	Finally, she gathered up the courage to step outside, her self-consciousness still consuming her thoughts. Leaning out the door, she looked both ways, stepping onto the entrance mat only once she confirmed there were no cars or passers-by. In her head, she knew her panicking made her a bigger target, but she couldn't help herself. Closing the door softly, as if sneaking out, she began speed-walking her way to a steady jog in the direction of the pharmacy.
	It was hotter than she'd expected outside, and the two traffic lights between her and the store were not on her side. She paced nervously at each corner, stress and heat causing sweat to run down her back and between her thighs. Her fur felt matted and sticky, and she hoped nothing would show through her clothes. Her family hadn't seen her that morning, though; in a worst-case scenario, she would be able to change before anyone got home. She might even have time for a shower!
	She felt as though she ran the last segment, bursting through the doors nearly panting, her face flushing deeply from a mixture of exhaustion and embarrassment. She knew she was drawing attention to herself, the only cashier and the few customers in the store glancing over at her. Catching her breath, she managed to mutter a response to the cashier's welcome before glancing around the ceiling for the aisle marked for diapers. Noticing the mirrors along the top edge of the ceiling, her heart sank a bit, until she realized she, too, could use them to her advantage, taking stock of where the other customers were in the store and plotting out her path.
	She began to make her way to the aisle marked "Incontinence products," but stopped short at the end cap of the aisle marked "family planning." To her surprise, adult products lined one half of the aisle, colorful boxes of condoms and bottles of lubricant alike, while the other half was plastered with pastel colors and colorful cartoons, stocked with baby supplies. She was standing at the end of the aisle where the diapers were stocked, the other supplies being toward the back. What had caught her eye, besides the curiously awkward layout, were the diapers closest to her, wrapped tightly in a colorful plastic case. They were specifically made for teenagers and older kids with bedwetting problems, or so they asserted on the package; even the largest size appeared to be covered in cute little cartoons of butterflies and flowers on the girls' diapers. They were  supposed to be like "real" underwear, which she could only assume meant simply that they were pull-ups, because they certainly did not look anything like normal underwear to her. Still, her heart fluttered. Would they fit her? They certainly seemed like they could. The prints on the package looked so cute; they reminded her of her own room, filled with clothes adorned with girly prints and a large collection of cute plushies and toys. She had never changed a diaper, she thought, so the tapes might be hard anyway. These might be better!
	With a sudden burst of self-consciousness, she came to, her eyes darting around to see if anyone had caught her looking at the bright pink pack of diapers in front of her. Glancing up once more at the mirrors, she grabbed the pack and hastily made her way back to the front of the store, only to find to her horror that there was a customer still paying at the front. She tucked the pack under her arm in an attempt to hide the childish prints, blushing deeply as she felt the presence of another customer entering the line behind her. Finally, the customer in front of her stepped away, and it was her turn. She slowly placed the pack up on the counter, barcode facing the cashier to ensure the transaction would go as fast as possible. After a short beep, she saw the cashier place the pack into a bag, only to find to her horror that the prints were clearly visible through the thin white plastic!
	"That'll be $11.29," the cashier said, indicating to the card reader.
	"Umm, thanks," Chelse replied shyly, tapping her card. "C-can I have a double-bag, please?"
	"Sure," the cashier said with a polite smile. Chelse only just now looked at the cashier, a kind-looking older woman who very carefully rebagged the pack before handing it over to her along with the receipt. "Have a nice day, sweetie."
	"T-thanks--you too!" she said before taking off, still feeling the eyes of the customer behind her. It wasn't until she got outside that she noticed the pink and purple were still visible, although the prints were at least partially obscured by the second layer of plastic. It was too late now to do anything else but hurry home and hope no one saw her!
	She arrived back home the same way she'd entered the pharmacy, panting and sweating from head to toe, slamming the door behind her. The bag rustled as it swayed from her wrist, and she hurries up to her room to hide its contents. Closing the bedroom door behind her, Chelse walked over to her bed before pulling the pack of diapers out of the bag, setting them on the bed as she tossed the bags over toward her desk to use for trash. She looked at the bag curiously, reading every little bit of text and observing every print on the pack before remembering the heat. Though her curiosity tore at her, she pulled herself away, stowing the pack now under her bed before hurrying off to take a quick shower and change clothes.

	It was not until late that night when the mouse was able to once again close her door and retrieve the diapers from under her bed. Carefully, she tore open the package, having observed earlier the thin perforation where the pack was meant to be opened. Pulling one of the garments out, she looked at it with great curiosity. It was much softer than she'd expected; much quieter too, though still loud enough to make her blush a little. She would definitely need to be careful about hiding the crinkling. The outside was covered in a soft fabric shell, printed with the same cute designs on the package; the sides were made of an unprinted magenta elastic that was perhaps the softest part of the diaper, and very stretchy. The inside proved to be a remarkable, if subtle display of modern technology to her; she noticed the layered leg gathers along the edges, as well as the layers of padding, with a mysterious blue rectangle in the gusset of the pad. She had expected the inside to be much more like her panty pads. The pad was understandably thicker, wider too, and left without textured grooves. She assumed that meant either that the lining was that effective at moisture-wicking, as the pack claimed, or else her urine would pool and possibly overflow. Though perhaps embarrassing and not what they were designed for, Chelse would not have minded the latter. The thing that caught her the most off guard though, was the unmistakeable smell of baby powder, subtle and sweet. It was actually rather pleasant, though it reminded her of what exactly she was holding.
	Slipping off her panties, Chelse changed into the diaper, tensing up at the additional noise as she slid it on, but instantly relieved by the surprising comfort and snugness. Looking over at her vanity, she switched on her lamp, turning in the mirror to take in the fit of the diaper on her backside. Looking down, she noticed a cute little bow printed on the front, right where the elastic gathered at the waistband. The smell of powder now wafted back to her snout, both calming and embarrassing her. Was this how Rhou felt? she thought, rubbing her backside through the diaper.
	She had intentionally avoided using the bathroom before going to her room, and she now felt the urge growing. She almost hated to ruin the cute little garment, especially so soon after having donned it. Her thoughts quickly turned to arousal, imagining flooding the diaper, feeling the warmth pool all the way up, spilling out the top of the waistband and the leg gathers, ruining the cute little diaper while she rubbed herself off through the squishy pad, tearing it open as Rhou had to finish herself off. Her fantasies didn't help her at all to let go; she had to clear her mind. Standing up in front of her bed, she spread her legs a little and closed her eyes, hoping that the little pull-up would do its job.
	Though she had trained herself to wet her panties for fun, she had never peed anywhere else naughty, and her wettings had almost exclusively taken place in the bathroom. Now, standing right beside her bed, the plush carpet between her toes, the diaper snug around her waist, she found it difficult to let go. Eventually, she felt the warmth; a small trickle had escaped from her folds. Holding her breath, she pressed a little harder, turning bright red as she heard a toot from her backside. She stopped instantly, scolding herself in her head, growing more nervous. She just had to relax. Eventually, she was able to feel release come to her once more, this time a little more. She finally began to feel the floodgates begin to open, accompanied by a soft "hisssss" which turned her on. Letting her paw drift down the front of her diaper, she reveled at the warmth. It was almost hot, certainly warmer than her panties got, and it was growing in her hand. The pad was becoming heavy, softer too, and it gave a little as she pressed slowly. Now adding more pressure, she began to rub herself, stopping quickly when she felt the pool of warm urine not yet absorbed in her diaper begin to drip down her thighs. Still, she continued to pee, simply enjoying the combined feeling of warmth and relief.
	As her stream faded, she crawled up onto her bed, desperate to reach beneath the pad and feel how moist she was, from both her own arousal and the puddle of pee she'd made. Getting on her hands and knees, though, she felt another urge build within her. At first, her reaction was to push back, to reject the thought. She wanted to enjoy the moment, to play as Rhou had. She had the time, and the privacy; she could even tear the diaper apart and finger herself with the gooey innards, maybe even taste them. But then...she had the time, and the privacy. She was already wearing a diaper, and a wet one at that. What difference would it make if...?
	It certainly wasn't on her list of kinks she'd gathered from the sleepover, but the thought wouldn't leave her mind. Her active imagination only took the thought further into the realm of extreme kink, torturing and tantalizing her as she stayed still crouched on her hands and knees, legs spread slightly by the bulk of the soft, warm pad. She'd never messed herself in her panties, or any time at all for that matter. Pee had sort of just happened in the midst of her arousal; it had come to her. But this, this was a conscious decision, just as the diapers were. This wasn't simply her losing herself in the midst of arousal, finding herself later surrounded by piles of colorful fabric. This was something she was thinking deeply about, considering, and that began to excite her. Was she actually going to?
	Closing her eyes and dipping her head slightly, she made her decision. At first, she found it just as difficult as wetting, perhaps even more so, since she'd never done it before. The diaper, snug against her butt, seemed to convince her body there was no room. Once again, she sat patiently, not daring to push herself, simply waiting for her body to take over. Eventually, she felt the pressure grow, and with a soft crackle, she felt an immense warmth once again fill her diaper, a new and very different weight now spreading along her backside. She gasped at the feeling, reaching back to feel the swell of the pad, tugging gently at the leg gathers and waistband to give herself more room to finish. It was soft, just as everything else had been, but slippery, and awkward. The scent entered her nose as soon as she'd finished; though it wasn't terrible, she still felt uncomfortable continuing her adventure here in her room. Hastily, she gathered up her panties and one of the plastic bags, now waddling from the awkward feeling of her mess squishing as she walked. Cursing the bag and diaper's noises softly, she snuck out of her room, and dashed into the bathroom across the hall, shutting and locking the door.
	Letting out a sigh of relief, she leaned back against the door, feeling her tail squish the back of her diaper. Her mess spread both up towards her tail and down, and she hurriedly stopped, the noise of the door rattling in place and the thought of blowing out against the door spooking her. Flicking on the light, she hobbled over to the toilet, putting the lid down. Now, nervously, she rubbed herself once more through the diaper, now purposely fondling both her wet pad and her mess, squishing both gently but finding no leak or major spread. A tad disappointed, but still swimming in anticipation, she turned her back to the toilet and sat down slowly, using her hands to steady herself. With the lid down, the toilet felt much higher than normal, and, like her first wedgie, she dropped down too fast, feeling her mess quickly spread beneath her. Blushing deeply, she spread her legs, checking to see if there was any mess. Her pad threatened to give way in the front, the pressure as if about to pop, while the back, still surprisingly warm, continued to move about. There was no mess on the seat yet, though the leg gather had visibly darkened, and the edges of the printing around the front were now tinged with gold. Feeling as though the back would leak at any moment, she gave an experimental, playful squeeze with her tail, squishing and then rubbing back and forth, feeling the mess spread all along her back side up to what gelt like the waistband. With a giggle, she now humped the seat, the pillowy softness of her diaper pressing back against her, almost like a plushie, but much wetter, and warmer.
	She felt her mess begin to spread to her front now, and though her initial reaction was once again to stop, Chelse was now too aroused to think rationally. She rubbed herself with her paw now, from the outside of her diaper, feeling some of her pee begin to puddle under her thighs. Without a second thought, her paw then slipped down the front of her diaper, confirming exactly what she had been imagining the contents to be like. Her fur was matted, moist with her urine, and her pussy was slippery, eagerly dripping and loosened for her fingers. She began to rub herself furiously, still humping the toilet seat, her mess making the motion almost effortless. Without thinking, she reached further back, drawing her dirty fingers across the front of her pussy. It made her flesh tingle, and she blushed at how dirty she felt as she kept rubbing, dipping her fingers back to smear her pussy again and again until she completely lost control, shoving her fingers inside her deep as she let out a moan, the world around her slipping into the void. She felt only her own pleasure and filth, keenly aware of each of her senses, but nothing else. The scent overwhelmed her just as the slippery feeling in her diaper did, as well as the hard toilet seat and its slick surface beneath her messy butt. Her tail twitched, only making her more aware of her mess, and her free paw gripped the edge of the toilet seat hard as she struggled not to grit her teeth.
	Finally, she stopped holding her breath, gasping for air as softly as she could. She felt her body convulsing, almost like a machine on short-circuit, her eyes and fingers twitching, her folds, still soaked, now convulsing in rhythm with her quickly slowing heartbeat, her toes curling and uncurling subconsciously. Her nose was pointed toward the ceiling; she seemed unable to move from her position for several minutes. Finally, she let out a long sigh, her eyes slowly opening, her fingers withdrawing from her diaper, still stained with her mess. She was now keenly aware of the feeling of her mess beneath her, and she finally began to worry about how she would clean herself up and change out of the diaper.
	Slowly, she gathered up a ball of toilet paper, wiping up the puddle beneath her, lifting the lid only an inch or so to drop the wad in before repeating the process until the lid itself was clean. Then, lifting the lid entirely, she now sat down on the toilet properly, pulling the bag closer to her. Carefully, she tore the sides of the garment as she'd read on the package, finding the process surprisingly easy. She was surprised it hadn't torn during everything else. Pulling it off of her slender frame carefully, she managed to drop her diaper in the bag without incident, before folding it up more and tying off the bag. Luckily, she was able to reach the shower handle from the toilet, switching it on, she began to let the water heat up while she cleaned herself thoroughly, finally flushing before stepping into the shower to clean herself off properly.

	After sneaking downstairs to toss the bag in the garage trash, she climbed back up onto her bed, laying down. She was too lost in thought to sleep. She could now cross off Rhou's diaper fetish, or at least part of it; she hadn't even thought to experiment like Rhou did in the moment. In fact, her experiment had taken on its own path; none of that had gone according to plan. And yet, she had really enjoyed it. The cleanup, though tedious, had not bothered her as much as she had initially thought it would; she'd even felt herself become aroused while cleaning, and had once again rubbed herself off in the shower. She now felt the same urge once more; now that she was cleaned up, laying in her shirt and panties, her thoughts drifted back to the realm of fantasy, the memories fresh and vibrant in her mind. She was still able to imagine each of her senses at any moment in great detail, and she climaxed a third time that night with ease. It definitely wasn't on her list, she thought, licking the cum off her fingers, a lingering scent from earlier still faint on her fingertips, but perhaps she had made her own discovery.
