About halfway through my coffee, I felt my stomach cramp and got myself into a semi-squatting position on the sofa, with my bottom hanging over the edge, and pushed out a couple of soft and mushy logs, smaller than the initial load but much softer, warmer, and smellier. I pushed again, let out some very bubbly farts, and felt the last small lumps of soft poo ooze out and into my nappy. Feeling very satisfied with my load, definitely one of my fuller nappies, I sat back down and felt the new hot load spread out and ooze towards my pussy.
I lay back and dozed in my mess, occasionally massaging my clit through the warm, squishy padding, bouncing my bottom in the mess, and breathing in the unmistakable odour of a thoroughly filled nappy as it filled the air around me.
Around an hour later, I came around and pushed out a couple of farts that were pushing sharply against my hole. They bubbled through my mess and brought with them a sudden cramping in my bowels. Thinking I'd probably do some more farts and let out a couple of small squishy lumps of poo to finish up, I immediately got back into a low kneeling position on the floor. Bracing my hands on the floor, I let out a string of loud farts before a torrent of mushy shit suddenly exploded out of me. It came out in waves, I was barely aware of my surroundings and was focused entirely on how heavy my nappy had suddenly become and how smelly the new load of poo was.
The whole room immediately stank and as I went to lower my bottom down and rest, I almost immediately met resistance. I reached back to feel my nappy and that was when I realised that this new wave of poo was twice as big as the one already nestling against my bottom and pussy. My nappy was absolutely loaded in a way I had only ever fantasied about. I gingerly walked upstairs to look in the mirror, and felt the huge smelly bulge in my nappy banging against the back of my legs as it sagged halfway down my thighs. I looked at myself in the mirror, my crotch now slightly yellowed and a good four inches of poo-smeared bottom cheek exposed where the nappy had sagged under the weight of my incredible load. I was only just getting started enjoying this magnificent mess but knew that my nappy was almost at capacity and likely to ooze poo everywhere if I tried to sit down. I started manipulating the big pile of poo hanging underneath my crotch and bottom, pushing it up into the back of the nappy where there was more space to contain it.
Poo started oozing out of the leg holes and plopping on the floor, smelling much stronger than the poo still contained within the nappy, and it was clear that this particular nappy was done. Determined to not cut my play short, I taped a second nappy on top of the first and pulled a pair of thick, lycra shorts over the top. The enormous pile of poo was now contained enough for me to carry on playing and enjoying my day. I couldn't stop looking in the mirror - the two high absorbency nappies along with the enormous pile of poo they contained, gave me a huge, obvious, nappy bum. Any leggings, skirts or pair of trousers I put on now would do absolutely nothing to cover my dirty, smelly, secret. My bottom bulged out with padding, my crotch had swelled to double the size as I let out another torrent of piss, and there was a huge saggy bulge in the back, a bulge which could not even be contained with two hands, a bulge which could only be a fat pile of poo.
I posed in front of the mirror, pushing my bottom out to show off my bulge and feeling the creamy poo spread everywhere. I spread the poo around even more by gently bouncing my bottom up and down on the floor. I then grabbed my vibrator, straddled it and ground myself into a very wet and smelly orgasm. I stayed in that loaded nappy for a couple of hours, mainly because I could only imagine how bad the clean-up would be and was putting it off as long as possible! I periodically pushed my vibrator back into my padded pussy and cumming again and again on my pile of poo, occasionally dribbling out small streams of piss, which kept the load in my nappy wonderfully warm.
When I finally came to clean up, the smell when I opened the nappies was incredible, you could smell it from a floor away, and there was poo everywhere. It genuinely looked like I was wearing another nappy made completely of poo. The innermost nappy was completely brown, inside and out, and weighed a tonne, cradling as it was a pile of poo the size of a melon. I used the second nappy to clean off most of the poo that I was still wearing and came away with a decent sized load contained within that nappy! Eventually I got myself all cleaned up and sat down to write this story. Letting myself air out a bit and will probably put a nappy on for bed tonight but I can't imagine any mess that will top that one!
