A Type of Punishment by ImoutoCommissions

When Lucy wakes up, cold and wet, she immediately realizes that she's 
failed her challenge from the night before. This isn't a big surprise to 
her, considering how impossible a goal James set for her, but still, now 
she knows another punishment lies in store for her, and she wonders what 
he will have in mind for this. With how cold and gross it is, she 
squirms, nudging him to wake him up and get this part over with.

James stirs from his sleep, and he quickly goes to check her for 
accidents, already knowing what he will find. Her crotch is squishy when 
he grabs at it, and he scolds her, saying, "You woke up a wet wittle 
mousey, didn't you? I told you to hold it until morning." As he's 
feeling her, he finds his hand grows wet, as her clothes are not fully 
able to contain the liquid, with some of her pee leaking out. Her 
pajamas have a considerable wet patch on them now, and he sighs, shaking 
his head.

He gets up and grabs the video camera, turning it on as he orders her to 
march to the bathroom to begin her punishment. Once in the bathroom, he 
films her as he says, "Now, strip down, and tell us about how you got 
where you are now."

Blushing, Lucy does as she is told, using her cutesy voice to tell the 
story as she strips all the way down to her thick panties, stained a 
very noticeable yellow. "Last night, big bwother got me all dwessed up 
for bed and told me to sleep without having an accident, but I couldn't 
make it, and I wet the bed."

"And now you're a big mess, and we have to clean that up," he says, 
setting the camera down on the counter, leaving it running as he 
approaches her, yanking down her panties and picking her up, placing her 
in the bathtub. He gives her a quick bath, and as he scrubs her down, he 
makes sure to pay special attention to all of her more sensitive areas 
so that, by the time her bath is over, she is already mildly turned on.

He then dries her off and carries her back to the bedroom, telling her, 
"If you're going to keep wetting yourself like a baby, then I might as 
well treat you like one, right?"

Lucy tries to protest, but she is cut off by him fitting her with what 
appears to be a cross between a pacifier and a gag, strapping it to her 
head so that it stays in place. It isn't long before he has her dressed 
up again, but this time in an actual diaper with a floral pattern, a 
small lavender dress that is short enough to expose said diaper, with 
matching ankle socks that have lace around the top. She looks every bit 
like the little girl James always treats her like, and she knows her 
"big brother" must be loving every second of it, and must have been 
waiting for the chance to try this.

He picks her up and carries her to the kitchen, revealing just how much 
he's planned for this when he shows her a barstool that he's modified to 
serve as a high chair for her. He locks her into it, her arms pinned at 
her side, leaving her to sit and watch while he cooks breakfast for her. 
Once he's finished, he brings over scrambled eggs and oatmeal, removing 
the pacifier so that he can feed it to her directly. She eats happily 
before drinking plenty of juice that he's fixed for her, unaware that 
he's spiked it with a strong diuretic and a mild muscle relaxer.

He is still recording her when he sits her on her feet in the living 
room, but the muscle relaxer causes her to take a spill as soon as she 
tries to take a step, and she blushes as the camera catches her falling 
on her diapered bottom. She attempts a few more steps with the same 
results, finally settling on crawling to get around, as James entertains 
her with childish toys and games, fit for a toddler.

She enjoys this quite a bit, but then, after a bit of time has passed, 
she suddenly stands up, trying to grab at her crotch through the thick 
diaper, squirming as she announces, "Big bwother, I gotta go potty!"

"Alright, little sister," he replies, but he leaves the room without 
helping her up to follow him. When he returns, he has an oversized 
training potty, modeled after a cartoon cat princess or something, and 
Lucy blushes as she realizes what he intends for her with this.

"I want to use the big girl potty!" she protests.

"I don't think you're ready for that yet. If you don't want to use this 
potty, then you can just wet your diaper," he replies, and she isn't 
sure what to do. She wants to prove that she won't wet herself like a 
child, but she also wants to convince him that she is big enough to use 
the actual toilet, not the training potty.

In the end, she does not get to make the decision for herself at all. 
Due to the drugs she consumed with her breakfast, she has less time than 
she realizes, and her sphincter is not able to hold out against her 
indecision. Suddenly, she loses complete control, and James is able to 
catch the exact moment on camera. She wets herself, but does not soak 
through her clothes like she's used to; instead, she feels the warmth 
trapped around her girlhood, and the dress is so short that anyone would 
be able to see how her diaper swells, filling with her pee.

"Oh nooo," she wails, mortified that he's filming it, that the moment of 
her first (adult) diaper soaking is immortalized. But what comes next is 
sure to be even more humiliating, and she knows that James won't 
hesitate to film that as well.

As expected, he changes her in view of the camera, teasing her as he 
does. "See, I knew you needed to be padded up," he says, as he untapes 
it and wipes her clean. "If you were ready to use your potty, you 
wouldn't have made such a mess, but it's okay, because you've got your 
big brother to change you, until you're ready to be potty trained."

He takes his time with changing her, drawing out his teasing as much as 
possible, before he gets her taped up in a fresh diaper, and asks her if 
she's getting hungry again. When Lucy agrees, he decides to get their 
lunch prepared, this time spiking her drink with something different. He 
gives her peanut butter and jelly sandwiches, and cuts it into small 
pieces, letting her feed herself that way, but her drink is put in a 
large sippy cup.

Lucy finishes every bit of her food, and James makes sure that she 
drinks every drop of her juice before he will let her up from the chair. 
By that time, her drug has finally begun to kick in, and she grows 
sleepier and sleepier. He picks her up while she begins drifting off, 
but she remains awake while he carries her first to her bedroom to 
change her into footie pajamas, a simple purple pair, then into the 
living room, sitting in the recliner and rocking her in his arms while 
giving her a bottle of warm milk. The bottle is a nippled baby bottle, 
but Lucy is too sleepy to protest this, and drinks it until she has 
fallen asleep.

James puts her to bed, putting a giant teddy bear between her arms, and 
she cuddles it in her sleep. He leaves the camera running in the bedroom 
before he goes off to do something else while he waits for her to wake 
up.

~X~

Lucy is squirming in her sleep before long, her drinks with lunch 
beginning to catch up with her. Her dreams reflect this, and she dreams 
of herself as about half of her height, wearing a kindergarten uniform 
that she must have seen on an anime James showed her before. She is 
running through a school resembling the one that kindergartner character 
attended, but each hallway turns into another identical one, and no 
matter where she searches, she seems to be completely trapped in an 
endless maze.

She has her hand pressed to her crotch, trying to keep herself dry as 
she races against her bursting bladder. "I have to pee!" she cries. "So 
bad, so bad, I'm not gonna make it!" And it really does seem that that 
will be the case, as she struggles to find the bathroom in what feels 
like hundreds of identical hallways.

"Help me," she wails, "help me, I have to pee!" There is no response to 
her pleas for help, and no one else around, and she considers giving up 
the fight completely. It is just as she decides that wetting herself 
might be her only option and the only way to stop the pain of her full 
bladder that she sees it- a sign with a pink figure of a woman. She's 
saved!

Lucy gleefully opens the door to the bathroom, heading to the toilet, 
and just as she is about to reach it, she is suddenly yanked back by 
hands grabbing her from under her arms. She realizes that it must be 
James holding her back, and she cries out, "Let me go! Before I have an 
accident!"

But when James lifts her up, he does not set her down on the toilet, and 
instead begins lowering towards his cock. The James she knows in the 
waking world is rather well-endowed, but the James holding her now is so 
large that the real world James looks small in comparison. This 
terrifies Lucy, who cries out, "No, no! Big bwother's big thingy will 
rip me apart!"

James does not listen to her at all, and continues to lower her down, 
until he pushes himself inside of her, and she screams out, which he 
again ignores. He wastes no time in pounding her, his thrusts so hard 
and fast that her tiny twatty can hardly handle it. He strikes her 
bladder with an intensity that she's never known, something that the 
real James would never be able to match. Her bladder swells and swells 
as she fights against wetting herself, until it looks like an overfilled 
balloon, extending from her stomach, growing impossibly large until she 
knows that it will burst if she doesn't let go. Fortunately her body 
does not leave her much choice, and the stored up urine explodes out of 
her, with the force of a garden hose, soaking her and James and the 
floor beneath them.

Of course, in the real world, there is nothing so dramatic. The camera 
does catch the moment when she spreads her legs, and her diaper begins 
to swell with the sudden release of her bladder. A moment later, she 
wakes up, her soaked diaper still warm, and she squirms uncomfortably. 
This is the second time she's woken up soaked today, but this time, the 
bed and her pajamas are left clean as the diaper is able to contain 
everything.

She gets out of bed, still struggling a bit to walk, though most of the 
muscle relaxer has worn off by now. Holding the large bear in front of 
her, as if trying to hide behind it, she toddles through the apartment, 
looking for James so that he can help her out. Eventually, she finds him 
playing video games, and stands there, watching him for a moment before 
he asks, "Do you need anything, Lucy?"

She mumbles, pressing her face against the bear's head, but James cannot 
hear her. He tells her as such, but it takes a few more tries before she 
is able to clearly and audibly tell him, "I need a diaper change."

Giving her a warm smile, he says, "Oh, yeah? Then let me take care of 
that for you."

This time, when he strips her down to change her, he takes his time with 
cleaning her up, being incredibly thorough around her girlhood, until it 
is clear that he isn't just cleaning her up, but that he's trying to 
tease her. She can't say that her dream didn’t leave her a little bit 
aroused as well, and his hands only increase that, until she wants him 
just as badly as he wants her. Lucy squirms under his touch, remembering 
that he hasn't properly fucked her since their outing the day before.

"Big bwother?" she asks. "Can you pwease fill me up? Can you stuff your 
thingy in your baby sister's baby kitty, and fill my tummy up with your 
boy milk?" She makes an effort to beg him as childishly as she can, 
knowing that he can rarely resist her when she does so.

And, just as she had hoped, his face softens and he says, "Of course I 
can, little one." With her still laying back in the changing position, 
all he has to do is free his erection, pushing inside of her quickly. 
Lucy cries out, both from the sudden fullness and from pleasure, and it 
isn't long until James is thrusting into her at a decent pace, though it 
is nowhere near as fierce as the fucking she got in her dream. Of 
course, considering how intense that was, she has no complaints about 
the real life version.

It doesn't take long for him to get her to climax, not with how pent up 
she was, and it isn't long after she comes that he joins her, triggering 
another orgasm in her, when she feels his seed shooting inside of her. 
For some time after that, the two of them rest in that position, Lucy 
enjoying the afterglow and the feeling of her big brother's seed soaking 
into her womb, but then, despite having just wet the bed, another wave 
of desperation comes over her.

The drug she unknowingly took is still in effect, and she is so quickly 
overcome with another need to pee, that when she expresses this 
desperation to James, and he reminds her that she has to use the 
training potty, she does not decline that offer this time. He films her 
as she sits on it and releases the contents of her bladder, and the 
relief is so pleasant that she can't bring herself to care.

Still, he reminds her that her day of punishment isn't over, so once 
she's finished using the potty, he has her lay back down so he can put 
her in a fresh diaper, and then back into her pajamas. They decide to 
spend the rest of the afternoon playing video games together, with Lucy 
nestled in James' lap while they play.

She has grown so used to this new role today that she barely even 
notices when she has to pee in the middle of a game later, and wets her 
diaper without realizing it. James, however, does notice, as he can feel 
a slight warmth on his lap as her diaper swells, and he can faintly 
smell the pee.

Pausing the game, he asks, "Do you need a diaper change?"

"Nuh uh," she replies, unpausing the game so she can continue. However, 
James just pauses it again and gives her crotch a squeeze, and when they 
both feel the squish, she blushes, looking away and realizing that she's 
caught.

~X~

After he gets her changed again, they resume their game for a while 
until they decide that, since it's getting late, it's time for dinner. 
James orders a pizza for them, which he lets her eat by herself. After 
dinner, the two of them take a bath together, with James dressing her in 
a fresh diaper and clean pajamas for bed.

In the back of her mind, Lucy wonders how many they've gone through and 
how many are left, starting to wonder about the fun they could have 
tomorrow, when James snaps her back to reality, reminding her, 
"Tomorrow, you go back to being a short adult with college classes, not 
just my little sister."

Lucy wonders how she's supposed to adjust back to that so quickly.
