Had anyone else been there, they'd have seen a pretty, 5' 4½", 22-year old brunette standing, alone, seemingly studying a display of nappies. They'd maybe have noticed her big, blue eyes and clear, creamy complexion. They'd definitely have eyeballed her gravity-taunting bosom and profoundly curvy body (32F-27-38, for those keeping score). But, nobody was there, and Naomi concentrated and tried to slow down her breathing. Her heart was beating fast and beads of sweat were forming at her hairline, dampening her tousled, chestnut locks. It was 7.45pm and the supermarket was near to closing time, so she had the aisle to herself (she'd chosen 'baby and shampoo' as it seemed appropriate for her plans).
Ever since 19-year old redhead Chloe had inserted herself into her relationship with Christina, her boss, the dynamic had not been the same. Christina loved to spank and cane girls. Chloe loved to be spanked and caned. It was a great match. Naomi also delighted in having her fleshy cheeks punished, but she had other, dirtier but equally strong peccadilloes that she wanted to indulge. When it was just the two of them, 38-year old Christina had seemed happy to explore, especially when Naomi then explored her body with her tongue, but now Chloe's enticingly chubby cheeks had stolen her attention she was less keen to wake up in a pissed-in bed or have a house that smelled like a toilet, so a distance grew between the lovers.
Naomi was still living with her boss, but she felt stifled at home. Which is why she was now standing in the nappy aisle at her local supermarket, alone. Alone and desperate to use the toilet. Not that she had any intention of doing that! Given Christina's changed tolerance in her dirty habits, Naomi had been using the toilet way too much for her own liking in the last couple of weeks. Rather than indulging her and then punishing her, Christina now just looked annoyed if Naomi turned up in front of her with soaked legs or a stinky load in her knickers, so she'd stopped messing at home and, as she was still Christina's secretary, at work too.
So, Friday night, nearly 8pm, Chloe undoubtedly laid across the bed Naomi and Christina still shared, having her teenaged-bottom thoroughly and painfully whipped, and Naomi was gearing herself up to go in her panties in public. She'd been planning this for days, but this would be her public debut. She'd wet herself outside on occasion, but her deliberate intention here was to shit herself, in public, half a mile from home. She was terrified and exhilarated in equal measure. And no way could she pretend it was an accident - this was a plan days in the making.
In the morning she'd dressed with tonight in mind. Bikini-style panties, cotton, in pink and white gingham - clean, which was odd for her as she liked to wear knickers that smelled of stale pee - another thing Christina recently found aggravating. She'd tried various materials, but liked plain cotton best, as it showed stains, which excited her, and was good at holding a load. Over them she chose black, calf-length leggings and on top a patterned mini dress that fell to her bottom. She knew this wasn't as brazen as she could've been - the black was picked to hide wetness and the dress to cover a bulge - but this public messing was a dry run. Or a wet, smelly run, more like. The dress was tight across her huge, soft boobs (which would draw the attention of most pairs of eyes that looked her way), and her feet were in white Converse low tops and trainer socks.
A quick glance told her she still had the aisle to herself. She realised she was in front of the adult-sized diapers and suppressed a giggle. Biting gently at her bottom lip, she willed herself to relax. This was it. She'd planned it. She'd imagined it all day. She'd chosen her spot. Now she was going to go in her pants, like a baby. No, not even like a baby - they had no choice. She was a dirty, perverted 22-year old who was going to use her panties as a toilet, in public, completely on purpose, because it turned her on. Just thinking that to herself made her pussy moist.
Another deep inhale and slow exhale. Her nipples were aroused, her heavy breasts felt warm, her cheeks were flushed. Then she began. The pee came first, initially a quick burst that soaked into the gusset of her knickers, then a longer flow, which spread in a wave down the material of the leggings on her inner thighs, running around the back to soak her bottom and the back of her legs, then running past the end of them, pale yellow streams glistening down her calves, rivulets of piss filling her shoes and, inevitably, causing a slowly spreading puddle between her feet. Ordinarily she liked to focus on the wetting, to enjoy the slow, warm, wet spread as she peed herself, but today she was rushing and she was still pissing when she felt her bowel shift and her bottom-hole start to open.
Naomi realised quickly that this was going to be messier than she'd planned - maybe drinking coffee all day had been a mistake. Normally her poop was soft, firm lumps, but as her anus pouted, what squeezed out into her wet knickers was a sloppy gush with the consistency of wet cement. It felt hot against her smooth buttocks as it smeared and spread, moulding against her bottom and trickling between her legs to seep into her gusset. She doubled over slightly as a second push delivered a bigger burst of soft shit. Two issues were immediately obvious. First, she'd expected big, soft lumps that would sit in her knickers, but this foul ooze was already creeping under the elastic of her panties and slimming down her legs. Secondly, the smell was appalling - a pungent, watery and unmistakable stink of shit surrounded her. She was suddenly scared now, and tears welled in her big eyes. This was much worse than she'd imagined.
She had to get out of here, that was the main consideration. She started to walk down the aisle, then stopped. If you didn't go out through the checkouts, there was a security guard scrutinising people to check for shoplifters, and scrutiny was the last thing she needed. Best buy something and use a self-serve till. Given where she was, Naomi grabbed a packet of adult diapers and waddled towards the cashiers, piss-filled shoes squelching around her soggy socks, sloppy load of shit in her knickers squeezing disgustingly around her bottom, thighs and, now, pussy, as the soft load oozed around her body.
