Work Text:
jungkook had been into diapers since middle school and finally began indulging in his fetish once he had guaranteed privacy starting at the age of 19. before that, he spent a lot of time watching diaper videos online, specifically ones of people shitting in them. there was just something about watching the back of a diaper fill out, that got him rock hard.
he had no interest in the contents inside or even the aftermath of what people would do with the diaper- it was just messing them that got jungkook going.
but he could never bring himself to do it. every time he put on one of his diapers to try and mess in it, he'd either chicken out or wouldn't have to poop at all during the time he was wearing the diaper-not to mention, the clean up just didn't seem like it was worth it, so it didn't bother kookie too much.
he was down to his last diaper in the pack before he bought another case for whenever he felt the urge to use diapers for sexual pleasure again, as the feeling came and went.
he laid the diaper out on his bed and stuck the booster pad into it. he sprinkled a generous amount of baby powder in it as well as applying some to himself. he intended on wearing this diaper for as long as he could to see how much piss it could hold- something he does with every last diaper in the pack. it was his own little tradition.
laying flat out on his back, jungkook slowly secured the diaper around his waist, taking in how good the inside of the diaper felt on his already hard and dripping cock. once it was taped on, he rubbed himself from the outside of his extra thick diaper. he couldn't help but let out a moan in pleasure. he hadn't looked at it yet, but just the thought of how thick his diaper was without anything even in it yet, made a little drool slip out of his mouth and down his cheek.
and then he decided exactly how he was gonna use that diaper.
he wanted it filled to the point where it couldn't hold anything else. so heavy and so saggy. that's all he wanted.
kookie knew that he couldn't achieve that with just his own piss alone, so he settled on filling it up with warm water added on top of whatever his bladder could get in there.
he stood up from his bed, grabbing the half empty water bottle off his nightstand and made his way to the bathroom.
he downed the rest of the water in the bottle before getting in the shower, filling it up again in the sink. he stepped into the shower and tipped the bottle back, chugging the water like there was no tomorrow.
he knew the urge to piss would hit him in a few minutes since he hadn't gone in a few hours. he could already feel the slight pressure building in his bladder, but holding it always made it so much better.
he bent over and turned one of the shower knobs, putting his bottle underneath it to refill it. he considered just putting the shower head in his diaper but he figured it'd be more enjoyable this way.
once the bottle was finished filling up, jungkook pulled the front of his diaper a bit and flipped the bottle into the awaiting padding.
the diaper soaked up everything so fast that jungkook's skin didn't even get wet. he groped the front of the soggy padding and although it felt good, he was excited to add more to see just how big and heavy he could make his diaper.
the cycle continued of him filling up the bottle, dumping it into his diaper, and groping it just to see how thick the padding was getting.
when the front seemed to get too full, he began depositing water into the back.
he kept going until he heard water hitting the bottom of the tub.
"it's already full?" he questioned. he looked down at his diaper.
it was so heavy that the tapes looked like they'd give any second. the thick wet padding was touching jungkook's ass and balls from how much it swelled. he lifted one of his legs and reached around behind him, grabbing the full padding and groaning.
when he put his leg down, he realized that putting his legs together was not even close to an option anymore. he rubbed the front of his diaper, shifting the padding up and down while moaning loudly. everything felt so good.
then jungkook remembered he still had to pee. the feeling in his bladder had gradually gotten more and more apparent and he was ready to let go.
at first, he tried to see if any of the padding would still catch it, but after he felt the hot piss pooling in his diaper and passing the leak guards, dripping down his thighs, he let it all go.
the piss was flooding out of him and pooling up in the diaper so much that it began leaking out of the top.
he felt so dirty wearing such a soggy heavy diaper but still managing to get covered in piss.
he pushed on the front of his diaper a bit as his stream was slowing down and it gushed out of the top and the leg holes, splashing onto the bottom of the tub.
that's when kookie felt it. that familiar feeling in his stomach.
he had to mess.
his mind was so cloudy from how full his diaper was that the thought of cleaning up didn't bother him right now. nothing bothered him about what would happen if he made a mess in his diaper right at this very moment. he stood straight up and pushed a slightly, a loud bubbly fart coming out instead of a mess, relieving the pressure in jungkook's stomach.
maybe he didn't have to shit after all, but he still wanted to see.
this time, he bent his knees a little bit and pushed even less than he tried the first time.
next thing he knew, kookie's hole had opened and he was pushing out one of the biggest messes he had ever made.
the first log was out and had pulled down the back of his diaper even more than it already had been. after another push, another piece slipped into the awaiting seat of his diaper adding onto the load he was making. he gave one more big push with a grunt and the biggest piece plopped it's way out into the diaper with a loud fart crackling out behind it.
at that one, jungkook thought about how he must've looked in the saggy bulging full diaper and came as the last of the mess smushed against his butt.
jungkook was drooling all over himself and panting harshly. his head was finally clearing from the fog and he started to become more aware of what he just did.
he just shit himself.
he couldn't believe it.
he stood up straight in shock as his had reached around to touch the back of his diaper. he couldn't even feel the definition of any mess because of how soaked the padding was.
he looked down between his legs to see how low the diaper hung and he could swear that it was almost halfway down his thighs.
he rubbed the front of the padding again one last time before undoing the top two tapes of the diaper and letting it slide down his legs, making a loud THUD as it hit the bottom of the shower.
he then promptly rolled up the heavy padding and tried using the tapes to hold it together but it just wouldn't stay from how big it was. he tossed it in the trashcan next to the shower that he'd take out the the garbage and silently washed himself off. the thought of his heavy full diaper made him instantly hard again so he got off in the shower after he had finished cleaning himself up.
he took the (heavy) diaper bag outside and tossed it into the bin, where it could manifest in it's stink.
jungkook made his way back to his room where he laid out on his bed completely naked.
he was so exhausted from how much effort he spent loading up that diaper that he knocked out cold after only laying on the bed for 5 minutes- but not before he had placed an order for a new pack of 12.
