Doubt creased Fay's brow, and she bit her lower lip as she questioned what her hot pussy and swollen nipples were telling her to do. Peeing your pants, and even the bed, and even your room-mate's bed! -- that was bad. But this, this would be so much worse. Could she really, deliberately, go all the way? Another spasm hit her, and a tear of pain leaked from her right eye. But, still, she was rubbing and pressing at her cunt through the peed in jeans and, still, she was making no move to get off Nadia's bed and get to a toilet. She started treading lightly, like a cat kneading cushion, her feet squelching quietly in her piss-filled pumps, and more tears, of pain and shame, slowly ran down her pretty face as the pressure in her bowels became unbearable, wave after wave of urgent, desperate need crashing against years of toilet training and good behaviour. She could not believe that she'd become this dirty and perverted this quickly, but whilst her body desperately needed to dump its filthy load, her mind was equally resolute that she'd not be taking her jeans and panties down.
A moment later, and it was no longer a battle. With a throaty sob, Fay felt one last throb of pressure and then moaned aloud as her bottom cheeks spread as much as her jeans would allow and a soft, thick turd squeezed out of her, sliding stickliy past her cheeks and pressing against the back of her now disgracefully soiled knickers. Such was her need to go that the tightness of the space available was irrelevant. The first log squeezed across her left buttock as a second, much bigger piece of poo emerged, squashily filling the available space at the back of her bulging jeans. Fay was in a trance, lost in the sensations, and the undeniable pleasure that she was feeling. Sensing that it was about to get harder to finish, she quickly unfastened the top two buttons of her jeans, and was rewarded by a third and fourth large turd oozing into her panty seat. Her whole bottom was coated with the stinky, brown mess, although, freed from the tightness of her jeans, the majority now hung in a dirty bulge under her bottom, the weight of the shit making her the waistband of knickers dig into the flesh over her hips. The smell reached her, but she was way past being appalled by her actions, and simply revelled in this new, dirty detail. She was standing in her flat-mate's bed and deliberately pissing and shitting in her knickers. What sort of girl did that?
Another, smaller lump of shit joined the obscene mess in her panties and, with a sigh, Fay realised that she was done. Only now, instead of a quick wipe and a flush of the loo like a normal girl would have, she was wearing her toilet. Closing her eyes, as if it would hide what she was doing, Fay reached behind herself and felt the fat pile of shit through her panties, testing the weight of the mess. Then, crying gently with joy and shame, she pressed the bulge gently against her bottom, feeling the poo mush against her cheeks and squeeze down, between her legs, towards her pussy. That was too much, and her hand flew to the front and down, inside her piss-wet, shit-filled knickers to rub and clasp her cunt, bringing herself to a shuddering orgasm in moments. The climax was so strong that red spots blurred her vision as she panted, trying to recover her composure.
Once she'd come back down, she knew she'd have to confront her situation. Or, could she carry on being naughty for a while? As was her new policy for making this sort of decision, she decided not to think it through, and immediately hauled her jeans back up as they'd sagged down her hips and re-buttoned them. This caused the warm, sticky poo in her panties to be squashed tightly against her full bottom, more creeping towards her pussy and some sliming up between her cheeks towards the top of her knickers. Turning her back to the mirror, all that was now visible (if you ignored the obvious pee stains) was a slight bulge under her bottom, the rest of the poo being moulded to her ass. Fay thought this a shame -- she was hoping for more visible evidence that she'd shit her pants. Next time she'd wear something else...that thought did get through. Next time? Had she gone insane? No, not insane, she'd just finally discovered what she needed, and what she needed was the most depraved, disgusting and dirty sex that she could conceive of.
Climbing gingerly off Nadia's soiled bed, acutely aware of her poo oozing against her bottom as she walked, Fay headed into the kitchen to get a drink of water.
