Writing trade collection (Fetish stuff)

Trying to show that I'm a big girl

This trade is for @Amyrose201

My name is Nica Blake, I'm 17 years old, I'm a college student who takes online courses, and I live with my two older brothers, Mike, who works at Bakery, and Stan, who works at some office, Mike is nice and kind, while Stan, he's nice, but he can be pretty cold from time to time, understandable since we lost our parents, a month ago, I was with them, and we ended up in a car crash, it killed them and I survived, however... My bowels have been damaged, so I was forced to go back into diapers, my brothers don't know this, and it's the reason why I take online courses, to avoid going out to college, I would never tell my brothers about my condition, until one day, at a Saturday, we decided to go see a movie, I was worried they would notice my diaper, so I decided to put on pants and normal panties, I did put a pack of diapers and some spare pants in the back of the car, just in case though, and so, we were soon off to go see a movie, Stan was driving of course, we would try to start chatting a bit

Mike: So Nica, what movie are you in the mood for?

Nica: Not sure, what are they showing right now?

Mike: I'll check my phone, hey Stan, what about you?

Stan: Look, I don't care what we watch, I'm just coming with you cause I have nothing better to do

Mike: Jeez, someone woke up on the wrong side of the bed, today

Stan: Don't test me... Hey Nica, you want extra butter on your popcorn, right?

Nica: Yep, can't eat popcorn without extra butter

Stan: Yeah yeah, we know how much you like butter on popcorn

At that time, I was wishing that Stan would lighten up a bit, ever since our parents died, he was acting like this, me and Mike managed to move on, while Stan, he still hasn't let go of the past, I was hoping one day, Stan would let go and move on, unfortunately... Those thoughts had to wait, cause at the moment, I felt pressure on my bowels, I start hold my stomach

Mike: Huh? You okay, Nica?

Stan: Should we be worried right now?

Nica: I-I'm fine, guys! I'm perfectly fine!

I lied! I was not fine! I needed to poop! I had so much pressure in my bowels! I seriously needed to go! But I chose to not say anything, oh boy, that would bite me in the ass later, my brothers then looked at me and got more worried

Mike: You sure you're okay, Nica? Do you need to go to the baghroom?

Stan: I guess we can take a detour...

Nica: No no! I'm fine! I swear!

I wish I did take that detour, cause I had to go so bad, fortunately, we soon arrived at the movie theater, I looked out the window and thought that there was still hope for me, maybe I could make it, once we parked, I suddenly saw that spark of hope fade away

Mike: We made it! Sweet! Now then, I was thinking, why don't we watch a-

BBBRRRRRRTTTTCCCCHHHHH

CCCCRRRRCCCCCKKKKLLLLLLL

Yep, I was starting to shit my pants, the back of them was starting to bulge a bit, the sound of pooping could easily be heard, I was embarrassed, eventually, I stopped pooping, and my brothers were looking at me, Stan was not pleased by this, judging by that look, he was pissed

Stan: You gotta be kidding me?! In my car?! Why?! Just why?! My seats better not be stained right now!

Mike: Stan! Screw your car right now! Nica, you okay?
