It's been a month since all her rights as an adult were stripped from her. Or at least, Belle thinks it's been that long. Time is a little hazy these days. At first, she tried to keep track of the days; every morning, when she woke up, she would repeat the number of days to herself, along with the day of the week that it was. I've been here five days. It's now Thursday. Day five, Thursday.
She tried her best, but it didn't take long for her to lose track. I've been here... eight days? Eight? And it's... Monday. Sunday. No, Monday. I think.
Now she has no idea. She tried asking her 'Daddy' once, but he just frowned at her and told her that little girls didn't need to worry about grown-up things like that.
"All you have to do," he said, tickling her under the chin, "is play with your toys and lie down for a nap when Daddy tells you and use your diaper like a good girl."
But it's been a month at least, she's sure of it. Daddy had flipped the page of the calendar a few days ago and the weather's definitely grown warmer since she first arrived in mid-spring.
That was when she had been caught shoplifting. That was when she had been told that she would have to pay a fine she couldn't afford or go to prince. Unless, of course, she wanted to take part in a new experimental community initiative...
The moment she said yes, she had been hauled to another room and stripped naked. She'd tried to protest, tried to fight, but a gag had been shoved in her mouth and she'd been wrestled into submission by four guards. A moment later, she felt a pinprick in her thigh and fell asleep. When she woke up, she was in an unfamiliar bed, helpless in a straitjacket. It took her a moment to realise that she was wearing something else, too -- a plain white diaper.
She tried to scream, but she was still gagged. She struggled to sit up and found that she was tied to the bed. When she turned her head, she saw that her bed was just one of twenty, all lined up in a neat row.
"Oh, good, you're awake."
Belle turned her head and saw a young man dressed in blue scrubs, holding a clipboard. He wrote something on the page as he looked Belle over. "Perfect timing. Your Daddy's here to pick you up."
Belle had no idea what he meant and tried to ask, but she could only make muffled sounds through the gag. The young man smiled. "It's so cute hearing you little ones try to talk," he said. Then, to Belle's horror, he reached out and squeezed the front of her diaper. "Still dry," he said, sounding surprised. "Well, it'll be nice and soggy soon, and I'm sure your Daddy can't wait to give you your first change."
Belle felt like she was in a dream, where people were talking and she knew all the words, but nothing they said made any sense. Her confusion didn't stop the man as he wheeled her bed out of the room and down a long hallway, right to Daddy's waiting arms.
Since that day, Belle's life has been more like a nightmare than real life. The man who insists that she called him Daddy looks after her like she was an actual baby. She isn't allowed to do anything for herself and every so often, someone from the "rehabilitative program" stops by to make sure Daddy is taking proper care of her. Belle isn't entirely sure what "proper" care meant -- if she's been bad, Daddy will sometimes leave her tied up in her crib for hours; he has spanked her until she bruised; he has left her in wet diapers, resulting in more than one case of a terrible diaper rash. He always looks so sad when he has to punish her. "This hurts Daddy more than it hurts you," he says, every single time. "I'd so much rather be playing fun games with my babygirl than punishing her. All Daddy asks is that his little sweetheart follows the rules."
There were a lot more punishments in the earlier days, when Belle was trying everything she could to resist and get out of here. Now, she is exhausted from so many failed attempts followed by harsh punishments. When Daddy tells her to open up so he could feed her, she obeys without any resistance. She never speaks without permission any more. He doesn't even have to tie her down for diaper changes any more.
And instead of punishments, now Daddy coos sweet things at her and cuddles her close while he watches movies. He wraps her in blankets and kisses her hair. On the rare occasion when he has to go out without her, he always comes back with a new stuffed toy for her.
Belle hates every second of it.
But the worst part of all is when Daddy takes her on her daily walk.
When she first came to him, she had assumed she would never see the outside of Daddy's house until her time in the program was up. (If only she could remember how long it was meant to be. If only she knew how long she had been her.) But it turned out to be the complete opposite.
"You're not a secret," he said to her, the first time he took her out. She was wearing her straitjacket; in the early days, that was all she wore because she wouldn't stop trying to escape. She couldn't fight back at all as Daddy pulled frilly ankle socks onto her feet and then squeezed the front of her diaper to make sure she was still dry. "All my neighbours know you're here and they've all been dying to see you."
When he lifted her into an adult-sized baby stroller, she thought she would die of humiliation. The feeling only got worse when he wheeled her outside and she immediately heard a woman's voice.
"Is that your baby? Oh, let me see her."
Apparently the rehabilitative program has really taken off and seeing someone with a trussed-up adult baby is not that unusual these days, but Belle is still the only baby in this neighbourhood. Every day, Daddy takes her on her walk and every day, neighbours stop to look at her and coo about how cute she is. They touch her diaper to check if she's soggy; they pinch her cheeks; they babytalk her and tell Daddy that if he ever needs a babysitter, to please please call them.
It's her least favourite part of the day.
But today feels different. The baby stroller Daddy pushes into the hall is new; it's not the plain stroller Belle has grown used to lying in, staring at the sky as she's wheeled down the street. (And, oh god, doesn't she hate that she has grown used to it.) It's fancier, with a seat that can be adjusted to a sitting or lying position. Right now, it's set to sitting up, and Belle can see the thick cushioning she'll be placed on in a minute.
"Do you like your surprise?" Daddy says. "I wanted this to come much sooner, but it took longer to arrive than I thought it would." He walks towards Belle and she automatically raises her arms for him to lift her. He grins and tickles her under the chin. "Eager little thing," he says. "Daddy has some things he needs to do first."
To her surprise, he untapes her diaper. She tries to wriggle away. "Daddy, 'm not wet," she mumbles, knowing that if she sounds childish enough, she won't get in trouble for speaking. For extra reassurance, she sticks her fingers in her mouth; he loves it when she does that.
Sure enough, his expression melts into something soft and gooey, like she's the cutest thing he's ever seen. Self-loathing curls in Belle's stomach. "I know, darling," he says. "But this is a special pushchair and Daddy needs to get you ready."
Belle squirms as he peels her diaper away. She's used to wearing them now and the air feels cool on her bare skin. Daddy kisses her on the forehead, then lays her clean diaper on the baby stroller seat. Only then does he pick up Belle and sit her in the stroller. It feels strange, sitting on her diaper without having it taped, and she wriggles. "Daddy?" she whispers. She isn't sure what she's asking.
"Just a minute, little one," he says. "You'll see what a nice surprise Daddy has planned for you."
He pulls a strap up from beneath the stroller and pulls it up between Belle's legs. As he does, she realises two things.
First, the strap attaches to two more than come down over her shoulders. Once the three of them are done up, she will effectively be trapped in the stroller.
Second, there is a thick dildo attached to the strap between her legs, perfectly positioned to slip right into her pussy as Daddy pulls the strap up.
Belle makes a small noise as the dildo is buried deep inside her. She hasn't been touched like this in... in... how long? How long has she been here? How long has it been since she had sex? How long has it been since she even thought about sex?
She shakes her head, trying to clear it. Daddy takes it as a protest and shushes her gently.
"I know, sweetheart," he says. "I know you're not used to be touched like that, but Daddy knows best." He does up the straps and cinches them tightly; the dildo pushes even deeper into Belle and she whines. The strap is tight against her crotch, pressing against her clit. The closest she has come to being touched like this in the last month -- two months? Three? -- is Daddy wiping her when he changes her diaper. On occasion, he paid a bit more attention to that area than Belle thought was necessary, but he'd never so much as stuck a finger inside her.
Now, Belle is stretched wide open, so much so that it borders on painful. She squirms and the strap rubs against her clit. She immediately holds still.
Daddy is watching her with a smile. "Some new feelings there, hey, babygirl?" he says. He puts on a pair of sunglasses. "Let's get you out for your walk."
"Wait!" she cries. He immediately frowns and she hurriedly sticks her fingers in her mouth. "My... my..." She hesitates, knowing she'll be punished if she uses any word deemed too grown-up for her vagina. Unfortunately, that's just about every word she can think of. "My, um, my kitty is showing."
Technically, she supposes that it isn't. It's hidden by the strap, but anyone who even glances at her will be able to tell that Belle isn't wearing anything. After being seen by all the neighbours in her wet diaper, she didn't think she could be embarrassed any more, but she's discovering that she can.
Daddy grins and tweaks her nose. "Oh, that's all right, little one," he says. "No one cares if a baby is naked. In fact..." He rips her pink T-shirt open and pulls the two sides apart, exposing her breasts, squeezed unattractively by the straps. "There. Now everyone can see your boobies, too, and you'll be able to see how much they don't care."
Daddy pushes the stroller out the front door and the dildo twitches. At first, Belle thinks it's just the jostling from the movement, but then she realises that as the wheels turn, the dildo is thrusting in and out of her. She tries to squirm away, but she can't move an inch. All she can do is sit there, trapped, and let the dildo fuck her in her pushchair.
Then the strap over her clit begins to vibrate.
By the time they're halfway down the street, Belle is sobbing. Whenever a neighbour stops them, Daddy stands still, but pushes the stroller back and forth to keep the dildo thrusting in and out of Belle. Everyone coos about how cute Belle is; several people tweak her nipples. One woman frowns down at Belle's bare crotch and says, "What if she has an accident?"
"That's why I have her diaper under her," Daddy explains. "I know my little girl won't get through a whole walk without wetting herself, but she's been such a good girl lately that I thought I should start introducing some treats, like letting her feel the air against her bare kitty."
The woman presses both hands to her heart. "Her kitty!" she says. "That's adorable!"
Daddy grins broadly. "That's what she called it earlier," he says. "Isn't it sweet?"
They continue on their walk and the feelings in Belle's kitty -- that's not the word for it, it isn't, but she can't seem to remember what it is -- are growing overwhelming. The dildo is making a slick squishing sound as it moves in and out of her. The buzzing on her clit is getting more and more overwhelming.
"Daddy," Belle says urgently. "Daddy, I..." She trails off, with no idea what to say. She knows there's a word for what she's experiencing, but she just can't seem to think of it.
"It's okay, darling," Daddy says, keeping his pace steady. "Press into it and let go. Let go for Daddy."
The feelings inside Belle's kitty crest and she throws her head back with a cry. Her body strains against the straps. Her chest heaves and tears trail down her cheeks. She comes loudly and several people in their gardens turn to watch.
"Good girl," Daddy says. He hasn't broken stride once. The dildo inside Belle now feels like it's too much, too much, too much....
"No, it isn't," Daddy says, and Belle realises she's been saying that out loud. "It's a good thing for a little girl to experience. Now settle down and enjoy your outing. I thought we'd go for a slightly longer walk than usual today."
Belle sobs so loudly that she's sure the whole neighbourhood can hear. The vibrations on her clit are unbearable and everything is wet and hot and --
She's wetting herself, she realises with horror. Daddy was right and she can't hold her bladder and she's peeing all over the diaper beneath her as the toys inside and against her drive her closer and closer to her next orgasm.
She sobs, loud and helpless, and Daddy tells her that she's a good girl. He waves at a neighbour and stops for a chat. Belle doesn't hear a word of it. She sucks on her fingers and sits on her piss-soaked diaper and grinds against her new toys.
She's sure she'll be out of here soon. Won't she?
How long has it been?
