You're at the airport, and you got there SO late. Thank goodness your flight was delayed due to the inclement weather, or you'd have fully missed it. You run all the way up to your boarding gate, ignoring how full your bladder is. You can pee in the airplane bathroom.
You hurry to your seat, red-faced. You truly were the last person onboard, you barely made it. All you can think through takeoff is that you can't wait to get into the air and for the announcements to stop so you can go pee. You're bouncing your leg. Thankfully you don't have any neighbors, so they can't be irritated by it. The lap belt on the plane and the tightness of the waistband on your jeans feel like they're tag teaming your bladder, pressing against it, but it still feels like everyone's staring at you, so you don't dare unbutton your jeans.
Finally, you're fully in the air, and you wait for the seatbelt sign to turn off. But, as you should have expected due to the weather, the plane almost instantly encounters some turbulence. The seatbelt sign stays on.
You watch a few shows on the screen on the back of the seat behind you. It doesn't distract you, you have to go. Both legs are bouncing now. Appearances be damned, you unbutton your pants. It feels like every time you relax even slightly the piss tries to get out. And the bumpy flight isn't helping matters, sloshing the liquid in your balloned bladder up and down and side to side.
You keep glancing at the bathroom, door wide open and unoccupied. Maybe no one would get mad at you if you just ran over there, you're sure you could make it even with the turbulence.
Half an hour passes. You leak into your pants a little, despite now clutching tightly at your crotch with one hand and biting down on the other hand. You can't hold it, you have to go so bad. It feels like it's all going to come out, blasting out of you like a pressure washer. Another leak spurts out, creating a tiny visible wet spot at your crotch.
You're so preoccupied that you don't notice that the turbulence has calmed, and the seatbelt sign has turned off. You do notice, though, when someone else runs into the bathroom. No, no, it was open and you missed it... You could be in there pissing right now, you're not going to be able to hold it until they get out. You stand (leaking again; the spot is a little bigger, now) and wobble your way over to the bathroom door, intent on being the next person in. Maybe you can make it, maybe, maybe...
You don't make it. It leaks again and then again two seconds later and then it's a continuous stream. You're pissing your pants in the middle of the aisle, it's streaming down your legs and into your shoes and socks and making a big puddle on the floor, spreading into the footwells of the nearby seats.
It feels like the world has stopped, you can't actually be peeing yourself in front of all these people, right?
You start to cry, bracing against a nearby seat, still wetting. When you're finally done, you start walking back to your seat, shamefaced, only to be halted by one of the flight attendants.
You offer a tearful apology, and she pats your shoulder. "There, there." she says. "We'll get someone over to change you."
You blink your tears away for a moment, confused. "Change me?" You ask. "You mean, you have spare clothes I can borrow on the flight?"
"No, silly." She says. "I mean we'll get someone to get you diapered."
Another flight attendant wheels a large cart down the aisle. On it are cleaning supplies, but the majority of the cart is taken up by what looks like a giant changing table, as if sized for adults. The flight attendant pushing it, dressed like the others but for an apron, smiles and pats the padded surface. "Up you go," he says.
"What- what do you mean?" You're fully bewildered. The strangest thing is that none of the other passengers seem to be noticing the crazy thing going on here.
"Hop up and lie down, so I can get a diaper on you," the aproned flight attendant explains, simply, as if it makes complete sense to say. "You clearly need it pretty badly."
You look around, expecting someone to say something, but all the other passengers appear to be in agreement, to your bafflement. One woman even chimes in. "I've never seen anyone more in need of it in my life."
Eventually, you yield to peer pressure and sit on the table, and are coaxed into lying down by the two flight attendants. They work together to get your soaked pants off, leaving you completely bare-bottomed in front of the whole plane. You cover your certainly-red face with your hands as you're wiped clean. The aproned one pulls out a puffy diaper (there's a picture of a caterpillar on it, you notice, despite your humiliation) and asks you to "Lift up your bum!" so he can get it onto you. He secures it tightly and gives you a little pat. "Up you get, kiddo."
You step off the table, feeling wobbly and lightheaded. The flight attendant who first talked to you leads you back to your seat, and you're almost too shell-shocked to notice that a padded, infantile, adult-sized baby seat has been added. She buckles you in, and hands you a big, soft teddy bear with airplane patterns that you can't help but hug close. "There you go, honey. Here, we'll put on some cartoons."
She hands you a big sippy cup full of juice, and then turns on some kind of animated show you don't recognize. You suckle almost mindlessly at the juice, just wanting to escape this whole situation.
And that's the first time you need changed on that flight. A few hours later, you realize a bit too late that you can't undo the buckles on the seat by yourself...
