I'll say that diaper pooping is literally one of my favorite if not my favorite activity. It's something I've been into for decades and am now 40 years old, so I have many memories of some world-class poops over my life.
All started when my parents were out of town and a babysitter was watching me. I was 7 years old. My parents had me wear a diaper at night at for wetting accidents that happened a bit but not nightly. Just a precaution. I was also uncomfortable pooping at school due to shyness and was quite used to holding it, which added to the volume quite a bit whenever I did finally make it to the toilet. In any case, I had been holding it a good day or so and felt an urge to really defecate shortly after she had put this (I'm assuming the brand) Pamper on me. These were well before clothlike nonsense so this was a thin plastic-backed one from like 1990. This detail is important because what occurred next was not subtle and the design definitely contributed to this embarrassing event.
I recall going up to her maybe half an hour before bed and the diaper was still obviously dry and I just wanted to let her know I needed to take it off to sit on the toilet. I started asking her for help and was suddenly hit with a sudden urge right when I was right in front of her. The fact I couldn't easily close my legs from the Pamper and I grabbed my butt and I couldn't hold it.
The big log I had been holding pushed out the seat massively and I remember the warmth and rich odor of dense poop, hearing the faint crackling from defecating and the crinkling of the plastic stretching, and the incredible relief all happening at once. I remember feeling shocked and helpless and turning around and her exclaiming, "Uh oh! You really had to go!" What was even more embarrassing was that I kind of had to finish pooping for several more seconds and together we waddled to the bathroom. I looked in the mirror and saw this gigantic solid mass in the seat. She laid me down and helped change me. I was kind of shocked when I saw the giant log just sitting in one piece in the seat. She told my parents the next day and I received no punishment for the accident nor did it ever happen again.
At age 11, I was hitting a growth spurt and still avoided toilets at school at a time when my bowel movements were getting huge, and the feeling of the large stool exiting was such a fanastic feeling in my bathroom. I did think many times about that feeling of a poopy diaper and at this time, was exclusively wearing white cotton briefs as underwear, and given every other boy at school was, felt no shame at that time of how boyish they were. I was, after all, a boy. So one day I had just finished a huge 2-day load and saw the tighty whities stretched around my knees and ankles and suddenly started thinking to myself that the cut really did look similar to that of a baby diaper, and thought the stretchiness would probably contain the logs I was pooping out, and just thought to myself, let's go for it!
I know that many here who are hopefully poop enthusiasts are now asking, how did I know I was not going to just shart out a big liquid stool and really mess up my briefs? Well, I was always quite in tune with my body and from the years of holding and inducing mild constipation, I knew I pretty consistently made thick dense firm logs (not the "ow I can't push this out" ones, but big dumps that came out with relatively no serious pushing. Aside from if I really tried to poop every day which made softer logs or the pretty occasional bout with diarrhea, I knew my body. Praise Buddha. I had achieved poop Zen and I was but 11.
So I sat on the toilet seat while wearing my little size 10 briefs and just pushed- I suddenly brought myself back to that moment years earlier- the feeling of the relief, the cotton stretching, the soft crackling of the BM collapsing into the seat, and the growing warmth that seemed to expand out to half my entire seat. I stood up and fell in love with the huge oval bulge and was surprised how well the briefs contained it, and how the load didn't seem to show any real staining even after a few minutes.
Cleaned up in the shower and was shocked to see the load had not even left more than some light streaks in the seat which could be rinsed easily away and tossed in with the laundry. Was approaching expert-level pants pooping by my teenage years, doing it at least once a week without being found out. Bought diapers by 16 and loved those too, but of course faced the disadvantage of hiding them in my room aside from the briefs which could hide in plain sight. Vacillated between the two activities in high school and college, met other men and women into it over the years which I'll save for later but yes, while I know not all ABDLs do this, I know I straddle in several camps, with DLs loving my still giant logs but raise an eyebrow at the pants pooping (still poop my briefs half the time), and with scat fetishists really not knowing why I'm not smearing it and have no interest.
In closing, thanks for listening and I would like to say that while my writing may sound obsessive, I really just want to give as many pertinent details as possible and for people to know that while I live a good healthy rich life with many friends, pants pooping and loaded diapers are a part of me, but don't define me- although it's been a critical part of who I am and my life.
