One morning, I woke up to my overnight diaper being dry, and decided that I wasn't going to change out of it before school, and was instead going to wear my padding to school. Choosing an outfit was hard, because no matter what I wore, my butt looked big due to the thick diaper. I ended up wearing sweat pants and a hoodie to school, because it covered everything up pretty well. Despite that though, my butt still looked big. I figured nobody would notice, because who goes around staring at people's butts, right? When I got to school, I noticed that it was significantly harder to walk than normal, and I had to walk with my legs spread out a bit. My first class went very well, my diaper didn't crinkle too much and I didn't have an accident. I was planning on going to the bathroom between classes, but the lines were so long that I realized I wouldn't have time to. So I ignored how badly I needed to pee and went to my next class. I was really struggling to hold in my pee in that class, so I asked to use the restroom. I was allowed to go, but the only gender neutral restroom was on the other side of the school, and I don't want to take off and put on a diaper in a normal restroom stall. I eventually had to slowly walk my way over with my hands pressed against my crotch. I could feel small amounts of pee slowly escaping and making their way into my diaper. By the time I got to the restroom, the only thing stopping me from wetting myself was the fact that I was pressing my hands into my crotch. I lifted my hands to open the door, and I instantly started peeing. I really wanted to stop it and I really tried, but I just couldn't. The good thing is I wear really absorbent night diapers, so it absorbed my full wetting and still had a good amount of dry padding, so my butt was still dry at least. The bad thing though, is I didn't bring any underwear or spare diapers, so now I had a more pronounced bulge in my pants. I took my hands off of the door handle and waddled my way back to class. I felt a warm squish in the front of my diaper as I sat down, but still only the fluffy feeling of a dry diaper in the rear. Eventually, class ended, I got up and waddled to my third class. It was hard to concentrate with the bulky, squishy padding in the front, but I made it through the class without incident. I really had to pee again when I got out of that class, but I saw how long the lines were and just said screw it and waddled over to the cafeteria, ignoring my urge to pee. I got in the lunch line to get a school lunch, and decided that there isn't a point in holding it in anymore. I released my bladder, and I felt the warmth and wetness spread from the underside of the diaper to the rear of my diaper, making my butt feel damp. I waited in line for about 10 more minutes and then grabbed my food and waddled my way to a spot under the stairs I usually eat at. As I ate, I gradually began to feel a pressure developing in my gut, and I realized I never pooped that morning. After I'd eaten, I went into the bathroom to see if my diaper was still hidden, and it was not in fact still hidden; there was a clear diaper outline bulging on my pants. Anyone who looked at my crotch or butt would instantly notice. I sighed, and then made my way to my next class. My fourth class went well, and I was able to ignore the growing pressure in my gut. Fifth class is where I had problems though. The urge got unbearable halfway through the class, but I still held on as best I can. When the bell rung, I began to rise from my desk, but I felt a weird sensation in the rear. I quickly realized what it was: I was pooping. I was pooping myself with two dozen people close to me. It was at this moment I was glad I chose to wear my diaper to school, because messing a diaper is easier to hide than pooping a pair of undies. At that point, I just let it happen, which was a big mistake because it was a big messing. My mess hadn't been contained in the rear of the diaper; a lot of it had spread to the front of it, making my whole diaper region damp, mushy and stinky. I left school at that point, because unlike most other people in my school, I don't have a last class. I waddled my way home in my soiled diaper, being super grateful I wore it today, because if I hadn't I would have peed AND pooped my pants at school today. When I got home, I decided not to change immediately, but to play some games in my full diaper. I turned on my Xbox and began playing Minecraft, ignoring the horrid stench coming from my rear. Eventually, my diaper region started to hurt from rash, so I paused the game, changed out of the messy diaper, cleaned myself and then had a decision to make: I'd had not one but two accidents that day, would it really be smart to not wear a diaper? But at the same time, would it be smart to wear another diaper right after getting a rash? I ultimately decided to change into a diaper instead of undies, which I did not regret because I did end up wetting myself in order to avoid getting up mid build. The build wasn't that great, but I'm glad I was able to make it look alrightish by keeping my focus on the game, not going potty. All I did the rest of the night was eat dinner, change into my night diaper and go to sleep.
