The sound of shuffling footsteps and a slight crinkle pulls your attention away from your book. You glance up, and there she is, standing in the doorway of the bedroom. Well loved stuffed kitty in one hand, the twisted material of her shirt in the other. She shifts her weight from foot to foot in the way you know she's hiding something.
You wait for her to say something, but the seconds tick on. Her eyes won't meet yours.
You choose to break the silence. "Did you need something, baby?"
She shrugs, but enters the bedroom and clambers onto the bed. Her gait is awkward and widened by the damp diaper between her legs. A thin set of short sleeve pointelle pajamas do little to conceal her padding. Her top rests just above her belly button and the diaper's crinkly white waistband pokes out from her shorts. She cuddles in close to you. You stroke her hair away from her face and look down at her, tucked in the crook of your arm with her stuffed kitty wedged between you.
"You gonna tell me what you need? Or do I have to guess?"
"Just wanna be near you," she mutters and puts her thumb in her mouth to signify she's done talking.
You aren't fully convinced, but accept her answer. It's sweet, and you'll never back away from extra cuddles. Your attention drifts back towards your book and a comfortable silence fills the room. Just your own even breaths, and the rhythmic thuck-thuck-thuck of her thumb sucking.
Something breaks the cadence, though. A familiar hitch in her pattern of breathing. Her breaths become shorter. Almost forceful. Huffier. Then, a muffled crackling noise followed by a sigh.
"Did you come in here just so you could mess your diaper cuddled up to me?"
All you get is a whine and a head shake in response.
She withdraws her head from where it was buried in your side and looks up at you, "I..I just like going near you. Makes me feel safe..."
It's incredibly endearing, and you would be embarrassed to admit how much her words (and actions) have turned you on. The idea of her doing something so humiliating and vulnerable just for you sends a rush of excitement through you.
"Well, I'm honored. Should we do something about that stinky butt?"
"Oh?' you say, reaching your hand around toward her bottom. You find the bulge weighing the seat of her diaper down and cup it lightly. Not applying any pressure, just resting your fingers over the shape of her mess. "You like having your messes right here?"
With the last word, you push your palm on her diaper and do your best to flatten the bulge in your hand. The plastic of the diaper crinkles and squishes delightfully under your hand.
She lets out a gasp when she realizes what you've done. It peters off into a moan.
"Tell me why," you say, pressing down again.
"It just feels right. I'm a baby. A baby who poops in her diapers. It should be there. I like it when it's warm, and, heavy, and, squishy, and-"
She's practically babbling at that point, finding it hard to hold onto coherent thought and speech as you knead slowly on her bottom. You pull your hand away and she whines.
"That's enough of that, don't you think?"
She just pouts up at you, arms crossed. She's the picture of innocence, with her red cheeks and dainty pajamas. But, you the know the real her. The her who is far from innocent and guileless.
An idea pops into your head and you feel yourself getting excited all over again.
"Why don't we play a little game, ok? If I win, you get changed, so that I can start breathing out of my nose again. If you win, you get another half an hour in that yucky diaper."
She nods her rapidly, and her eyes widen like a cartoon character.
"I'm good at games," she says, "I beat you in board games all the time!"
"I know you are, but let's see about this one..." you say, reaching into your bedside drawer. You grab a familiar blue and white wand and place it on the bed between you. Her eyes narrow in on it, and she looks at you with her mouth slightly parted and eyebrows tilted in confusion.
"Mommy and you are going to use the wand together, at the same time. Whoever lasts longer gets what they want."
She nods again, slower this time. Her cockiness from just a moment ago is fading. You shift and settle on your knees and tug your own pajama bottoms down to reveal your underwear, a damp patch starting to form on the front. She follows suit, and shuffles on her knees close to you, little shorts around her thighs. Your bodies provide pressure from either side, with the wand supported by your grip on the handle.
With the press of a button the toy comes alive, spreading vibrations across the surface of her diaper and your crotch. You would think the thick padding would stifle any pleasure she could get, but it's quite the opposite. She's described it to you as feeling like her whole lower half is being stimulated, and you can only imagine how hard she's trying not to succumb to it. She's letting out little mewing moans and scrunching up her face. it's obvious she's caught between trying desperately to get more stimulation, while also knowing she can't finish too fast or her fun will end. You don't blame her for wanting the best of both worlds.
You grind against the wand, trying to keep eye contact with her, but it's hard. The waves of pleasure are cascading over you and staying focused on not finishing isn't so easy for you either. The vibrations are hypnotizing and all you can think of is more, more, more.
For a few minutes the room is filled only with the sounds of the buzzing wand and each of your quick breath's and occasional moans.
Until, "M-mommy, I don't think I can, I think I'm gonna..."
You lock eyes with her and push your hips forward so that the toy applies extra pressure to her padded crotch, and it seems you've found the exact right spot to send her over the edge.
The moan she lets out is theatric, and she pushes herself off the wand, flopping on her stomach. With her shorts tugged down you can see the staining on the back of her diaper, no doubt worsened by the past few minutes of wriggling.
You can feel your own orgasm building, but you manage to hold on just long enough to mutter, "Oh, poor baby couldn't hold it," and with a final pulse of vibrations you double over the wand and shudder. The front of your underwear is glistening and slightly pulled to the side.
Later, after a thorough diaper change and your own wipe down, you're cuddling on the bed while some cartoon you aren't really watching plays. She squirms in your arms and looks up at you, a grin on her face.
