Summary
     Armin suffers from urge incontinence. Jean enjoys it.
Notes
See the end of the work for notes
God, Jean is about to expire from boredom. It's lesson five on a Thursday, the
teacher is late, he stayed up too late last night playing Call of Duty, and he
just really wants to go home and sleep.
He watches Armin out of the corner of his eye. The boy's acting like he's got
ants in his pants, shifting in his seat and looking nervous. Jean's about to
lean over and ask him whether his mother's trying out new washing powder or
something when Armin bites his lip, shoves a hand between his thighs and
squeezes his crotch.
A bolt of desire goes through Jean like William Tell's arrow through the apple.
So that's what the matter is: little Armin needs a wee. Going by the restrained
yet frantic squirming, he really needs a wee. Why didn't he just go earlier
between classes? That pee dance makes it look like he's needed it for a while.
Armin makes a motion as if to stand up, placing his hands flat on the desk -
and then sinks down again with a little moan, squeezing himself frantically
through his trousers and rocking back and forth.
Suddenly, he relaxes. He lets go of his crotch, face turning pink. Is he-? Jean
sneaks another look at Armin's face, realises how still he's gone and yep, he'd
say that his friend is wetting himself. In class. Man, this is about to get
awkward.
But where's the piss going? There's no puddle forming under Armin's chair, no
smell, and yet if it's coming out of his dick it must be going into his
underwear-
- Into his underwear, but not through it. Jean feels his eyes roll back in his
head as he connects the dots and realises that Armin must be wearing something
under his clothes to soak up the piss.
Oh god, Armin must be wearing a nappy.
Unfortunately, this is the moment when Mr. Shadis arrives and a deathly hush
falls over the room, so Jean can't nip off to the gents' and wank himself
silly. No, he just has to sit there, knowing that Armin is sat next to him in a
wet nappy which must actually be pretty uncomfortable, which is wet because he
just pissed himself in a classroom and no-one else knows. Jean restrains
himself from humping his chair.
They both head off to the toilet after the lesson, Jean keeping his bag in
front of himself because not even Shadis' creepy stare and occasional bellowing
could daunt his erection. Is Armin walking a bit awkwardly? Is he imagining it?
He looks to be in his own little world, a worried frown creasing his brow. Jean
wasn't meaning to stalk him, but he finds himself hanging back, following Armin
to the less-used gents' loo on the first floor. There are a couple of guys in
there, washing their hands; Armin slips into a stall, Jean into the one next to
it. He doesn't think Armin's noticed him.
The other boys leave, and the bathroom is silent. Jean stifles a cough and
tries not to breathe loudly. On the other side of the thin MDF partition,
there's rustling. Jean wishes desperately to spontaneously develop the ability
to see through walls.
More rustling. He'd get down on his knees and look under the partition, but
Armin would definitely see him.
A different tone of rustling - a lighter, thinner material. Jean doesn't know
precisely what's going on, but he knows it involves Armin taking off his wet
nappy and - putting on a fresh one? Jean imagines it in his head: Armin wiping
off his little dick - which he knows is small and cute because he's snuck a
peek in the changing room - and wrapping himself up in a new nappy, to be worn
under his clothes, all around school, and no-one knowing.
The moment Armin leaves the bathroom, Jean has his dick in his hand. He wanks
quietly but vigorously, leaning on the wall and closing his eyes. How long has
Armin been wearing nappies to school? How has no-one noticed yet? He doesn't
wear them for PE, because someone would have seen the bulk, so he must take
them off beforehand - so what does he do if he's caught short during PE? Jean
imagines Armin doubled over, clutching at his dick through his gym shorts as
pee turns them dark, and comes.
~*~*~
The new Disney film is pretty good, as films ostensibly aimed at children go.
Armin finds himself giggling at all the jokes, which makes a nice change from
all those really depressing French films they’ve been watching in lessons. He’s
seen French comedies advertised when he was on holiday in Marseilles, but if
Mme. Bauer’s film collection is anything to go by, they might just have been an
elaborate hoax.
He leans to the side slightly to get his plastic cup of water, and takes a long
drink. Except, as he realises when it touches his tongue, it’s not water - he’s
grabbed Eren’s soda by mistake. Armin hasn’t drunk soda in years, ever since
his bladder issues appeared, nor tea or coffee or orange juice, because while
he works on control it helps if he doesn’t consume diuretics. He grimaces, puts
down the soda - which he’d never liked much in the first place, so giving it up
hadn’t been such a hardship - and finds his water a couple of inches from where
he picked up Eren’s soda.
He’s totally fine until the film starts building up into the climax. He shifts
in his seat to relieve his numb bum, and discovers a slight pressure in his
abdomen. Ugh, this is terrible timing.
Normal people, he knows, would feel that and think nothing of it: just a sign
that while they don’t have to pee now, they will in a while. If they didn’t go
to the bathroom within the hour, they’d be rather uncomfortable.
In the next twenty minutes, Armin will have either gone to the toilet or wet
himself. It’s the fault of his overactive bladder: any minor urge to pee leads
in short order to a urinary emergency, and he has a lot of minor urges. It’s a
massive thorn in his side, being both inconvenient and embarrassing. What
fifteen-year-old has to pee ten times a day and can’t hold it for more than a
quarter-hour? He’s had to be put back in nappies, for god’s sake.
He goes back to paying attention to the film. The protagonist’s best friend has
revealed himself as the guy who killed the protagonist’s girlfriend some years
ago; except it was an accident, and his crushing guilt led to him being
vulnerable to manipulation by the villain, who has used him to gain vital
intelligence on their rebel operations. The actors are really giving it their
all; it’s gripping stuff, and probably going entirely over the ten-year-olds’
heads. Can this actually be made by Disney? Did they really mean to market this
for kids? Has the German dub just been totally mistranslated?
Five minutes later Armin squirms unhappily, squeezing his penis between his
thighs. The urge to pee just keeps getting stronger, but he can't leave the
film now. He knows he could just use his nappy, but that's not what it's there
for: it's for emergencies only, not for when he could go to the bathroom but is
busy with something.
But oh god, he's going to leak any minute. He assumes everyone else is too
focussed on the film's climax to pay attention to him, and takes the chance to
squeeze himself tightly. He can't get a good grip through the thick padding,
and he can feel his control slipping. If he keeps fondling himself he's going
to get a hard-on, which would help, but his bladder aches and oh fuck, this is
an emergency. He starts rocking back and forth, but that makes the seat shake.
He feels his cock dribble, and the dampness around the head makes it impossible
to hold it any more: the flow starts up as he wets himself there in the cinema,
surrounded by his friends. He feels himself blush: no-one can tell what he’s
doing, but every time he has an accident he’s half-convinced someone will
realise, or he’ll leak, or that somehow he’s forgotten to put on a nappy and
he’s actually peeing his pants.
He lasted sixteen minutes from beginning to end, and after all that not much
urine even came out. On screen, the film has just turned to the epilogue, which
seems to involve a lot of barely-veiled homoeroticism between the hero and his
friend. Ignoring the dampness encasing his cock, he leans back to enjoy the
last few minutes.
Everyone heads to the bathroom en masse once the film is over: soda consumed
over a two-hour period affects everyone the same way. Armin goes with them so
he can change. He’s got good at doing it quickly and quietly, so as not to
arouse curiosity. The other boys seem to assume that he uses a stall rather
than a urinal out of shyness, and thankfully don’t tease him about it.
They have on occasion teased him about carrying a messenger bag everywhere -
‘Armin’s handbag’ is its nickname - but never taken it upon themselves to rifle
through it. Jean had once made for it years ago, but Armin’s short, hard nails
in the tender skin of his wrist had dissuaded him. There are advantages to
being mentally grouped with ‘the girls’ by people like Jean, one being that he
could rest easy in the knowledge that Jean would not take this as invitation to
join in the frankly alarming horseplay that goes on among most of the boys in
their friendship group. Armin sits with the girls above it all, often
literally: Christa and he because unlike everyone else they haven’t done
martial arts for years, and Mikasa and Annie because they have no patience for
fooling around and prefer to end fights quickly, decisively and often
painfully. Christa’s girlfriend Ymir, on the occasions when she’s come out with
the group, seems to have been grouped with the ‘guys’ for these purposes; Armin
can comfortably admit that she's considerably more masculine than himself.
Armin pushes his trousers down to his knees, grimacing at the sodden nappy - it
hasn’t leaked at least, but the texture of a wet nappy hasn’t become more
palatable over the years - and whips it off and into a disposal bag. He swipes
at his inner thighs, penis and testicles (still smooth - the puberty fairy is
taking its sweet time to get round to him) with a baby wipe, drops that in the
toilet and flushes it, and tapes on a fresh nappy, the crinkling sounds covered
by flushing. He pulls his jeans back up and is ready to go. The wet nappy will
have to stay in his bag until he can find a suitable disposal unit, probably at
home, but it’s safely bagged.
It is, perhaps, a little sad how good he’s had to get at this.
Jean comes up to wash his hands at the sink next to his. His cheeks look a bit
pink. But then, it’s quite easy to get Jean to blush once you know which
buttons to press - which Armin does with regularity, because rough-and-tumble
Jean blushing will always be funny to him. His great dream is to one day see
Reiner blush, but that would probably be a cold day in hell: Reiner is
unembarrassable, and Bertolt seems to do all the blushing for both of them.
Jean sits next to him on the bus too, which isn’t weird - they are friends, and
the only other open space is by Eren, whom he is forbidden by common consensus
from sitting with on account of how they don’t want to be thrown off the bus.
The fact that he seems to keep one eye constantly on Armin as if estimating him
is odd, though, because when God was handing out tact Jean was in the toilet.
He’s congenitally blunt: it’s not his style to keep trying to work something
out subtly without having first gone the obvious route of just asking.
But Jean says nothing about what's bothering him, just keeps up idle banter
with the rest of the group, and Armin puts his weird behaviour aside to
consider some other time.
~*~*~
God, sitting next to Armin through that film was torture. Maybe it's
unflattering to admit that he deliberately bagged the seat next to him in the
hope of watching him have an accident, but since his hopes were vindicated,
Jean can't feel too bad. There, in the cinema, surrounded by all their friends,
he got to sit there and know that Armin, just inches away, was squirming about
because he had to pee, then actually wet himself. Jean had clutched his drink
in sweaty hands, listening not to the film but for Armin's little sounds of
discomfort.
He didn't wank in the cinema bathroom, because he's got some standards, so he
just had to keep his jacket covering his crotch and try to think of other
things all through the bus ride to his stop. He all but flew upstairs to lock
himself in his bedroom, lean against the door while tearing open the button and
zipper of his jeans, and wank furiously, head tipped back and mouth open.
He has absolutely got, he thinks as he wipes off his hand, to do something.
~*~*~
“Take that!” Armin has to laugh at the triumph in Jean’s tone. When not pitted
against Eren’s stubbornness, his competitiveness is quite amusing since he’s
not a sore loser in the end. Well, not for more than a minute, anyway - that
is, when the loss isn’t against Eren. Armin still isn’t quite sure just what
Jean’s problem with Eren is, aside from him having Mikasa’s undying devotion
and being totally impervious to Jean’s attempts to bully him, but since the
dislike has persisted from when they were only eight, it’s probably fair to
assume that it no longer has a rational basis.
Armin takes tighter hold of his own controller and flips his car back upright
and makes his it follow Jean’s, narrowly avoiding the traps dropped behind.
He’s come a long way since he was first introduced to racing games and spent
his first five tries running into walls and getting hopelessly lost on the
course: Eren would be proud.
As he shifts he feels the base of his penis tingle: after this race, he’ll have
to excuse himself to the bathroom.
But he let Jean pick the course, and he seems to have picked a really long one,
so after a couple more minutes they're only a third of the way to the finish
line and Armin is feeling distinctly more uncomfortable.
He can’t hold himself, because Jean would see, so the best he can do is squirm,
hoping it passes as excitement over the game, trying to squeeze his penis
between his thighs. it would be easier if it were bigger, he thinks, but
there’s nothing he can do about that.
It gets harder to hold on as they reach the middle of the course, and Armin is
getting worried that his jiggling is too obvious. The friction has made him
half-hard, which at least he knows can’t be seen. Jean hasn’t said anything
yet, though, and he can usually be relied upon to tell you exactly what he’s
thinking, so he figures he’s okay.
He wishes dearly that he could just drop his controller and dive for the
bathroom, but that would look too weird and Jean would make fun of him forever.
Two thirds of the way through the course, and Armin is having real trouble
holding on. He knows it's stupid: if he were to just let go now, Jean wouldn't
know a thing and he'd be much more comfortable. But it's so embarrassing. He
can't overcome the instinct that tells him that he can't pee, he's still
dressed: he can't willingly make himself wet and get it over with, so every
time he ends up wriggling about in desperation until the urge grows too strong.
"C'mon, Armin!" Jean is taking advantage of his spotty concentration to
manoeuvre his car into the lead. Now that can't stand: Armin isn't as loud
about it as Jean, but he has a competitive streak too, and he feels like
exercising it. He cuts a corner and rams Jean's car, sliding back ahead. Jean
swears; Armin grins and settles himself more comfortably on the floor - and
there goes the urge, overwhelming his clenched muscles.
And so, with the bathroom less than ten feet away and Jean right there, his
bladder gives out. Pee trickles out of his urethra, then turns into a stream,
and in seconds he’s peeing full-force into his nappy. His character slides into
first place just ahead of Jean’s, and the combination of virtual victory and
bladder relief makes him whoop. Jean grumbles something under his breath, but
he’s grinning too. He turns to Armin, squints at him assessingly for a moment,
then says,
“Hey, Armin - you just pissed yourself, right?”
Armin, who is in fact still peeing, opens his mouth but produces no sound. The
stream of urine slows to a trickle and tapers off. He’s wearing a nappy, right?
He knows he put one on just before Jean came over. He’s not just soaked his
trousers - hell, he’d have felt it if he had.
“It’s pretty obvious once you know what to look for,” Jean continues. His
controller dangles from one hand as he gestures with the other. “You do a
little pee dance and jiggle about, and then you suddenly stop and go really
still.”
“Jean,” Armin protests weakly, “you can see I haven’t wet myself.” He gestures
vaguely to his dry crotch. He can feel himself blushing incriminatingly.
"Except you obviously have," insists Jean. "And if no one can see that you
have, then you must be wearing something underneath to hide it."
Oh god, Jean's figured out his secret. Jean, of all people. Armin shakes his
head, but can only lurch backwards in horror as Jean drops his controller and
starts yanking at his trousers.
"Stop it, Jean!" Jean easily avoids his flailing arms as he undoes Armin’s
jeans and pulls them down around his thighs, revealing the bulkiness of his
nappy.
“Ha!” he says triumphantly. Armin wants to die.
He also kind of wants to pee still. He tries to get up and get to the bathroom,
but Jean, who is taller and stronger, pins him. His face is flushed - with
triumph, Armin supposes.
“Jean, let me up, I need to pee,” he begs feebly. Jean just pins his wrists
above his head.
“I don’t need to let you up for that,” says Jean cheerfully. Oh God, he’s going
to make him wet himself while he watches. Armin’s mortification is complete.
“Jean,” he pleads.
“Armin,” says Jean, teasingly. Armin squirms, feeling the pressure in his
bladder grow, but Jean originally met Mikasa and Eren at karate and they’ve all
kept it up since with fierce competitiveness, with the result that most of
Armin’s friends would be a mugger’s worst nightmare - and plenty strong enough
to hold him down.
"C'mon," says Jean, "I'm not gonna be mean about it or anything. I just wanna
see-" Abruptly the slight flush on his cheeks turns into a proper blush.
"You want to see me wet myself?" Armin renews his struggling under Jean, though
he knows it won't do him any good. Oh God, he's going to pee, he can feel the
pressure in his bladder. He tried hard to shed his crybaby tendencies and
reputation when he started high school, and largely succeeded, but right now he
feels like bursting into tears. "Jean!"
Overcome, his bladder gives up and, with a defeated whine, he feels the warm
stream of urine start. He closes his eyes in humiliation. Let Jean do what he
wants: he can't bear to watch him smiling at this.
"Fuck," whispers Jean. Armin keeps his eyes closed and tries to ignore Jean's
weight on his legs. "Fuck-" says Jean again, with hitching breath, and Armin
opens his eyes because that didn't sound like amusement. The stream of pee
tapers off: he didn't have much in his bladder anyway.
For a moment, he can't work out why Jean is pressing his hand to his crotch; it
just doesn't register. Then he realises that Jean is rubbing at his erection
through his jeans while staring at Armin's crotch. He looks seriously turned-
on. How did he not notice that Jean was hard?
Armin licks his dry lips.
"Since I've just had to wet myself in front of you," he says quietly but
firmly, "you have to wank in front of me." His heart is in his mouth, but he
feels it's the moment to be daring.
Jean looks up at his face, startled.
"Fair's fair," says Armin. When Jean doesn't move he adds, daringly, "C'mon,
undo your trousers." He knows his own face is as red as Jean's. Is he really
going to do this? Well, some rational part of him calmly points out, it's not
like he has any dignity left to lose.
Slowly, Jean undoes his jeans. He hesitates a moment, then pulls out his dick.
It's the first erection Armin has seen in person aside from his own. It's -
bigger than he'd have thought. Quite a bit bigger. Apparently Jean isn't only
horse-faced. It's a deep purplish-red, wet at the tip, and looks painfully
hard. It twitches when Jean touches it.
Brick-red, Jean shyly slides the foreskin back and forth a few times; then,
seeing that Armin isn't going to shriek in disgust and push him off, starts
masturbating seriously. He bites his lip and tucks his chin into his chest; his
eyes keep trying to close, but he keeps opening them to stare at Armin's nappy-
covered crotch. Did seeing Armin wet himself really excite him this much?
Jean suddenly takes several harsh breaths through his nose, accompanied by
whines in the back of his throat growing higher in pitch - 'Mhmm, mhmm, mhmm!'
- and his mouth opens wide in silent exclamation as he comes, hips jerking back
and forth erratically into his hand. His semen lands on Armin's bare thighs.
He slumps forward, thighs still quivering. Armin gives him a moment before
clearing his throat and saying,
"Er, you're a bit heavy..." Jean looks up, startled.
"Yeah, yeah, of course," he mumbles, climbing off Armin's legs and putting his
dick away. Armin sits up and stretches: his floor isn't very comfortable.
Laboriously, he pulls himself to his feet.
"I'm going to change," he says, pulling off his trousers entirely from where
they're tangled around his calves. Jean's seen it all anyway.
Out of the corner of his eye he sees Jean, still sat on the floor, open his
mouth and run his tongue over his teeth.
"Can - can I watch?" he asks, uncertainly.
Armin's heart is thudding in his ears and he knows his ears are bright red, but
his voice is light when he says,
"Yeah, sure."
End Notes
     The original prompt:
     Armin suffers from (stress induced?) male incontinence and has to
     wear diapers/incontinence pants. He is very insecure because of it.
     Jean or Eren find out by accident and it turns out they have a
     wetting kink. Armin ends up no longer feeling as terrible about the
     whole thing.
     My preferred scenerio for Jean/Eren learning about Armin's problem is
     they saw Armin wetting his diaper in class, realized what's happening
     because of Armin's expressions and squirming - as he first tried to
     hold off wetting (the diaper being there for emergency, toilet is
     always is preferred choice) and then the expression of pure bliss as
     he finally let go. Jean/Eren gets really turned on by the sight and
     the thought that Armin's sitting there in his wet diaper.
     + Jean/Eren rubs Armin's dick through the wet diaper until he cums in
     it
     + Jean/Eren changes Armin's soiled diaper for him
     + the character asks or "forces" (for example by pinning down) Armin
     to wet himself in front of them when he could use the toilet
     + cute little dick for Armin
     (I actually gave Armin urge incontinence, though I don't claim that
     this is a remotely accurate portrayal of the condition).
