Work Text:
When Producer finally spotted the rest stop sign glinting in the afternoon sun, it felt like a divine wind. The air in the charter bus had gone thick and stale about an hour outside of Okayama. It was a dense, recycled fog of warm bodies, soured road trip snacks, and a very cloying ammonia smell that was an unfortunate consequence of the logistics of taking so many idols so far.
A few of the girls had real incontinence issues that needed to be managed whenever they didn’t have easy access to a bathroom; most didn’t, but on long bus rides few could be trusted to hold it. It was simply a fact of life at 765 Pro. And in any case, what went together better than teenaged girls and diapers?
The bus hissed to a halt in the dusty gravel lot, and the 765 Pro idols erupted in a collective groan of relief, popping joints and peeling themselves off the sticky vinyl seats. "Alright, ladies!" Producer called back over the groan of fifteen sore backs straightening up. “Thirty minutes! Stretch your legs, and get some drinks from the vending machine if you like. This is the last stop until we get there.”
A hand shot up from the middle of the bus. “It’s like 40 degrees outside,” Mami said, as she looked with one eye at her phone. Ami filled in the implication. “Can we take off our clothes?”
Producer wanted to protest that it wasn’t really that hot outside, but when he stepped to sample the air he could immediately sympathize with them. It must have been the humidity. “Fine, you can leave your clothes in the car. Just keep your underwear on."
A chorus of relieved sighs and creaking joints answered. Within seconds, the aisle was a river of bare legs, perky chests, and flashing smiles, echoing steps, chatter, and crinkling. Haruka, bless her, was already helping Yayoi navigate the steps while simultaneously adjusting the waistband of her own gym shorts over a suspiciously bulky rear. Yukiho was giggling nervously as Makoto, clad only in a crop top and a pair of panties that barely covered the thick padding taped around her hips, pulled her towards a vending machine.
And then there was Chihaya Katsuragi.
She was standing by her seat, her expression a perfect storm of resignation and discomfort. Her dark hair was plastered to her temples with sweat, making her look even more waifish than usual. Her thin cotton t-shirt hung off her narrow shoulders, and below the hem, her legs were bare. Between them, a sagging, yellowed shape hung heavy and low, the elastic gathers of her plastic-backed diaper stretched to capacity. A "Chihaya Special," it was called in the staff chat - soaked to the point of near-failure. She was holding the hem of her shirt with white knuckles, not out of modesty, but out of the specific, chafing misery of a wet diaper on a hot day.
"Come on," Producer said softly, nodding toward the shady patch of grass near the bus's front tire where the changing mat was laid out. "Let's get you out of that."
Chihaya didn't speak, but the flash of relief in her sharp, amber eyes was loud. She walked over stiff-legged, the heavy diaper forcing a slight waddle.
“Clothes off?" she asked, her voice a low murmur. The Producer nodded, and her white cotton tee came up over her head and back onto the bus.
There was now nothing between everyone’s eyes and the sweaty, lithe, flat torso above her bulky diaper. She had the body of a pre-Raphaelite boy, save for the swollen, crinkling garment between her legs. Her flat chest glistened, and big beads of sweat collected on her sternum. Her belly was so concave you could see the faint outline of her abdominal aorta pulsing under the skin.
Producer knelt before the mat, and Chihaya obediently laid herself on it. Her body was stiff like she might get punished for touching it to the ground out of order, until her head touched the plastic cushion. Then it relaxed, but just halfway.
Producer pulling out his phone and propping it up on his bag. The sun was perfect; golden hour filtered through a tree canopy, making the cheap plastic backing of her diaper gleam like silver satin. Good lighting for the Insta, he thought, as he framed the shot.
He peeled the tapes. Riiiiip. Rip. The sound echoed in the quiet corner of the lot, and they felt a few pairs of eyes drift their way. Iori was leaning against the bus's grille, stretching her hamstrings. She let nothing stand between anyone’s eyes and the cute pink bunny-themed diaper she’d brought from home, nor the spare she was clutching below her tiny, developing (but still larger than Chihaya’s) bust. She was watching with a detached, professional curiosity, unfavorable comparing his taping technique as compared to her butler. Behind her, Miki was trying to see if she could fit her hand inside Yukiho's diaper without Yukiho noticing. Quite silly of her, really.
The front panel fell away, and the scent of urine wafted out. Nothing foul could come out of her, but it was quite potent. Her hairless vulva was slick and pink, the skin around it red and slightly irritated from the chafing she'd complained about. Her anus was also red where it puckered around the butt plug, which on such a long trip was as necessary for her as diapers were in her everyday life. Chihaya exhaled a long, shuddering sigh as the weight was lifted from her groin.
"Lift up," Producer said. She planted her heels on the mat, and he slid the sodden, heavy mass out from under her. He left it bunched just below her, ready to hold the wipes he’d use. "Feet up, Chihaya."
She complied immediately. She drew her knees up, and he placed a hand on the back of her calves, pressing her feet back toward her tiny breasts. The tension in her audibly eased as her Producer took control.
"Ah—" A tiny, barely audible sound escaped her throat as her Producer pushed. It was the stretch of her hamstrings, the press of her thighs against her stomach, and a little added squeak of embarrassment form the exposure of her crotch.
Producer laid his weight into Chihaya, causing more noises to emit from her. “Do you need to poop?” She shook her head. Nevertheless, he pushed again, pulled, and extracted her butt plug. With the quick application of a wipe and a little more lube, it soon went back in. Chihaya was able to handle this stoically, from experience if nothing else.
Next producer ran the cool, wet wipe over her labia, but now she shuddered. "Good?" Producer asked, swiping down the crease of her thigh.
"Do it again," she whispered, her hips twitching. "Press my knees down more."
Producer obliged, putting a firm palm on her shins and folding her nearly in half. As he wiped again, he realized she was rocking, almost imperceptibly, into the pressure. He began to wipe more thoroughly, trying to get every crease clean, but she kept squirming. Not away, but into it. He paused, looking down at the small, pink bead of flesh nestled at the apex of her folds. She was wet, and not from the diaper.
"You want something else?" His voice was low enough that only Iori's straining ears caught it.
Chihaya opened her eyes. They were glassy, pleading. She didn't have the words for it. She just pushed her pelvis up toward his hand.
Producer dropped the wipe and used his aloe-slick thumb. He pressed down hard on her clit, squeezing it between his thumb and forefinger through the hood. Her back arched off the mat; her mouth opened in a silent, perfect 'O'.
"That's it," he murmured. He squeezed the little pearl between his index and middle finger, rolling it with the precise, firm pressure she couldn't replicate on her own. Her face was a mask of agonized ecstasy; he rubbed harder. He pinched, and then he tolled the nub between his fingers in an unforgiving circle. Her thighs began to tremble violently.
"Ah... ah... ah..." she chanted in a breathy, desperate rhythm. Her back arched off the mat. Her flat, sweaty chest heaved, the tiny nipples hard as pebbles. Her face was twisted in a silent scream of pleasure. Her legs trembled against your grip, her feet kicking uselessly in the air. Iori was now staring at them with interest, not just the usual sense of superiority.
Chihaya came hard. It was a full-body convulsion, a wet, squelching release as she squirted a thin, clear stream of fluid down over her perineum and onto the soggy, used diaper waiting below her. The Producer kept rubbing, drawing out a second, smaller shudder.
"There," she gasped. "More."
He gave her more. He squeezed her clit like he was trying to pop a grape, and she came again, this time a gush of slick wetness that audibly splattered onto the waiting padding. Her back arched off the mat; her flat, sweaty chest heaved and thrusted up her tiny pebble-hard nipples. Her face twisted in a silent scream of pleasure. Her legs trembled against the Producer’s grip, her feet kicking uselessly in the air. She squirted like a broken faucet. By the time the fifth wave hit, her legs could kick no more, and they were released.
Chihaya collapsed onto the mat, chest heaving, a tiny, satisfied smirk on her lips. And then, as if her body had been waiting for permission to fully relax, it happened.
A clear, golden arc shot up from between her legs. It wasn't the one-off squirts of before, but a strong, picturesque stream of pale yellow urine that rose a good six inches before splashing down directly into the center of the used, and now even more soaked, diaper. It went on for a solid six seconds, a perfect parabola of relief glinting in the summer sun.
She sighed of pure bliss. "Good," she murmured, her eyes closed. "Now the new one will stay dry longer."
Producer laughed and lifted her legs again. On her right buttcheek landed three solid, stinging swats. Smack. Smack. Smack. The sound made Miki jump and Iori smirk. Chihaya just moaned.
"Bad girl," he said, my tone devoid of any real scolding. "Making a mess of the clean-up."
The Producer bundled up the catastrophically wet diaper and set it aside. Then, he grabbed the new one, fluffed it out, and slid it under her raised, obedient bottom.
He dusted her with a cloud of cornstarch-scented powder, then spread a thick layer of zinc oxide cream over her reddened inner thighs and labia. She hummed in contentment.
Finally, he pulled the front panel up, snugging it tight against her flat tummy, and taped the sides with a practiced, firm pull—one, two, three, four. She was sealed in; dry, soft, and secure.
Chihaya sat up, the new diaper crinkling loudly as she shifted her weight. She looked up at her Producer with huge, wet eyes. Then, before he could stand, she threw her thin arms around his neck, pressing a firm kiss to his stubbled cheek.
"Thank you," she breathed.
And then, just like that, she was up, padding away on bare feet and thick diaper across the hot asphalt toward where Haruka was waiting. Haruka held out a bottle of water with a gentle, understanding smile.
"Chihaya-chan! You look comfy now!" Haruka said, her own diaper crinkling as she turned. Chihaya Katsuragi just smiled and took the water.
“Iori,” the Producer addressed the closest he’d had to an audience. “Should I check yours?”
With a waveringly suppressed smile, the Little-Devil Forehead Idol meekly stepped forward and presented her padding.
