You're at your mum's friend's son's house.. he's not quite enough to be considered a friend. The two of you are playing Minecraft when you suddenly get a cramp in your stomach. You haven't went in days, nearly a week now, and it needs to come out. You're wearing a diaper, surely he won't notice? You shuffle around a bit until it's comfy.
No.. I can't hold it. This poopy needs to come out, and it's going to be a solid and large one.
Fortunately, your friend leaves the room so you lean slightly onto your back, spread your legs, let out a big fart then push.. and push again.. and again. It keeps turtleheading, so you stand up to crouch then push some more. Just as it's coming out, your friend returns and sees you actively doing a poo.
"Aww, does baby need to do a dump?"
You quickly stand up and pull it back in to act like nothing's happening.
"No??"
"Yeah you do! Why were you squatting down and pushing a load out??!"
Your face turns bright red as they come over and pull the waist of your trousers back.
"You're wearing a diaper!"
You turn to a state of panic and heavy embarrassment, so just say nothing. They go into a drawer and pull a diaper out, then get you to turn around while they put it on.
"I really need a shit," they laugh. Suddenly you feel more comfortable and have relaxed too much to realise you've been pissing yourself while your friend has been putting their diaper on. Suddenly your friend crouches down and pushes, before looking up at you. "Well, are you joining me or what?" You decide to join them by also crouching down next to them and pushing, to see who can mess their diaper first.
Your friend does a wet fart then makes an almost moaning noise while they fully mess their diaper, making it drop a little bit. While they start wetting their diaper, it's your turn to mess it. The urgency from before and you push.. and push.. and push until it makes a massive squelching noise and fills the seat of your diaper.
"Woah! That was a lot!" your friend comments, already rubbing their load against the floor.
