The club

It was for an investigation. Izaya was undercover. He wore extensions, contact lenses and the awful maid costume, complete with short skirt and stockings. The thigh gap was a must. The same with the false breasts and cut out holes where there were teats. They were heavy and full of milk. It was by far one of the weirdest clubs he'd been to.

"Izzy! Booth in the corner."

Izaya sighed and made his way over. There were two types of customers. Those that had a lactating fetish and littles. He'd learnt a lot just on the first night and now nothing surprised him.

As he got in view of the booth he caught sight of a pale blue onesie. A little. The better option since they didn't give him perverted, lust filled looks. For the most part it was innocent reenacting, they played the mother role and the littles fed. At worst he'd have to deal with a grown man in his lap.

"Hello there." Izaya forced a smile. "Is it feeding time?"

The man looked plain and uninterested. His attitude didn't scream daddy like most of them did. "Ah yeah, the little one needs feeding. The agency recommended this place."

"Which one?" Izaya asked sliding into the booth.

"Little adoption. It's our first meeting. I'm new at this."

Izaya flicked his gaze around the room spotting the uniformed watcher. If they were worried they'd take the little to safety, especially those in full regression.

"How nice." Izaya said. "How old?"

"Old enough to crawl and feed on his own." The man shrugged. Izaya could already feel the disappointment directed at the man.

"Should we get on with feeding then? Is baby hungry?" Izaya asked softly. He didn't have the size advantage but more than a few times he been confused as a daddy. "What's his name?"

The man paused raising another flag. "Baby." He shrugged.

"Okay. Baby, time for feeding."

The little untucked from the man's side and crawled towards him, bonnet and pacifier pointing out his needs. Izaya winced slightly as the little curled up on his lap, head against his chest and suckled. His hand moved to stroke the little's hair, strays of blond poking out. Izaya twirled the pacifier around his finger.

When the little was done, he opened his mouth for the pacifier. Izaya guided the little up and rubbed at his back. "Hey! What are you doing?" The man snapped.

Izaya looked at him calmly. "Burping him." The little made a small noise. "See."

"Just give us the cheque." The man tugged the little's arm sending poor baby falling towards the floor. Izaya grabbed him and held him tight. He waved to the uniformed watcher and the large man came over glaring at the so called daddy.

"I've seen enough. I can't trust one of our littles with you." The man said. "Get lost and don't bother coming to our agency."

"Fuck this, I'm not paying. Freaks." The man snarled and stormed off drawing attention. Izaya felt the tears on his shoulder. He hated bullies.

The man sighed and gently rubbed the little's back. "Sorry about that Shi-chan. Let's get you back home, away from the scary mean man." The man spoke softly and then normally with him. "Thank you for your help…Izzy."

"Sure." Izaya glanced at his name tag before easing the little away. The big man picked him up with ease. The little waved, curled against the man's chest and slept.

"Send the bill to the agency please."

Izaya recognised the larger little. He'd had to attend two of the daycare events and both had been hell. Yet the sight of one of the other workers, having the little drink from them made him bristle.

"Izzy." Izaya turned seeing the watcher from the agency. There were about four of them today. "Good to see you again. You're good with them."

"It's my job." Izaya shrugged.

"It's more than that. You know what they need. You're a carer. You have the qualities of a daddy."

Izaya swallowed. "I'm not. I don't fit the mould."

"Who does? Well if you change your mind. We have plenty of littles for adoption."

"You sound like a salesman." Izaya murmured. "What about the one from before?"

"Shi-chan? He's a potty trained full regression. Except he doesn't talk and doesn't cry. He doesn't fit the mould either. We'll find him someone."

"Like the guy before?"

The watcher scowled. "That was a mistake. But it's why I'm here. This place isn't exactly safe either."

Izaya coughed swallowing his breath. "What?"

"You I trust. The milk I don't." The watcher walked away, crouching down in front of the little. The milk. Why hadn't he thought about that?

The same little was back, this time wearing cat onesie. Izaya went over the the booth, his jugs full. His gaze caught on the same watcher, nodding to him in greeting. "Hello, Shi-chan. Here for feeding."

The little nodded and smiled with his pacifier in his mouth. The man next to him, the daddy looked a bit gruff but better than the other one. "Yes, little Shi-chan needs a feeding before nap time."

The little climbed into Izaya's lap, settling against his chest. Izaya gently tugged the pacifier and the little latched onto the teat. Again he stroked the little's head whilst he suckled. The man was watching him, as was the watcher.

The little finished drinking and moved without Izaya having to guide him. He rubbed the back of the onesie and waited for the small sound. Izaya frowned as he heard a whisper in his ear. "Daddy."

"All done." Izaya forced a smile and guided the little from his lap. "I'll leave you to it. Enjoy your stay." Izaya walked away.

The milk didn't leave the building. Security made sure everything was removed before they left the premise. It seemed the littles were okay. It was just the lactation fetish that contained something extra. They were dressed slightly different and had a smug look as they strut around. But he did notice some of the other customers talking that made him uneasy.

That was why he turned up to the Little adoption agency as himself. The receptionist wouldn't let him in unless he was there as a potential daddy. So he asked about Shi-chan and mentioned the potential.

"Oh! Take a seat. I'll have someone with you shortly." The woman beamed and reached for the phone.

It was the watcher. "Changed your mind?"

"No, it's the only way the receptionist would let me past. There's something in the milk and more of the customers are talking to the gold bands. Are all the littles from your agency?"

"No. We have a watcher per every two littles. But at the end of the day it's either a kink or a lifestyle."

"What's the difference?" Izaya asked.

"A kink is for sex. Role play if you will. It's a hobby. A lifestyle is someone that needs it. They balance out the big so they don't break. That's why they either need a dedicated daddy or a controlled environment where they can embrace their lifestyle without judgment or harm. The company you work for is a grey area that we can work with. But if we were to hire someone in the company it would damage both reputation and the safety of the littles."

"Sounds like you get paid a lot." Izaya commented.

"It's not cheap." The watcher shrugged. "But it's what they need. Most of the staff have dealt with children, been carers or looked after the elderly."

Izaya sighed. "Do you know what's in the milk?"

"I have an idea. I'm sure there's a menu."

"Maybe your agency needs to stop using." Izaya suggested.

The watcher smiled. "You'd make a good daddy."

"No, I've just seen how trusting the littles are and how rubbish these 'daddies' are."

The watcher continued to smile. "I'd give you some one on one time with Shi-chan but he's in big mode. He'll be in little mode for the weekend."

"I wasn't asking." Izaya shook his head.

"We'll see. I'll walk you out."

Izaya sighed but followed the watcher. Thankfully the man didn't ask anymore. As they reached the first floor, Izaya stepped to the side to let the person walk past him. What was Shizuo doing here?

"Shizuo, hey wasn't expecting you." The watcher smiled.

"HR called me in." Shizuo grumbled. "See you uncle."

"Sure, take it easy. Come in earlier if need be."

Shizuo grumbled a response and walked past them staring at his shoes. The watcher watched and sighed. "You know the way out. I hope you change your mind." Then he was left alone. "Shizuo, wait up!"

Izaya's brain had stopped. He held onto the banister, trying to process what he'd seen. It could be Shizuo was staff or maybe he was a potential daddy, he sure had the build, but the way the watcher had acted... Izaya frowned. The names were similar but he couldn't see Shizuo being a little. There was no way innocent Shi-chan was Shizuo Heiwajima.

Izaya caught a flash of a purple onesie but no watcher. It wasn't his area anyway. He felt a pang of guilt as a gold stripe strutted past him to the daddy and his little. He knew what it meant and dreaded what cocktail was mixed in with the milk.

"Hey, Izzy! Phone call for you. Says it's Shi-chan's uncle."

Izaya walked over and took the phone. "Hello?"

"I might have a problem. HR had a financial issue and until it's taken care of Shi-chan isn't with the agency. The problem is he's a stickler for routine. If he ends up at your company, please look out for him."

Izaya swallowed. "What financial issue?"

"He missed a payment. The guy in accounts is an asshole and only there because his father owns the business. I offered to pay it in the meantime but the asshole won't budge."

"I'll look out for him. Do you know what he's wearing?"

"He owns seven onesies. Dinosaur, pale blue, one with stars, a green one, a purple one, one with sea creatures and - are you there?"

"Purple?" Izaya murmured. "I have to go." He hung up the phone and moved towards the booth.

"Izzy, booth five. Lactation fetish."

Izaya bit out a curse and kept an eye out for the purple onesie. He'd seen it. "Damn it." Stopping he looked around and then went up to one of the security guards. "You seen a daddy and a little in a purple onesie? They forgot to pay."

"Yeah, guy just left. Looked like he'll have a good time."

Izaya unstrapped the milk, twirled and pushed out of the building. Sure enough there was a purple onesie being pulled along into a car. Izaya bolted, thankful the man was having trouble. "Hey!"

"Hey man, I already paid. Get in the car." The onesie slid against the side swaying dangerously.

Izaya pressed his switchblade against the man's throat. "Fuck off!" He warned. The man swallowed pushed him aside and ran. Izaya caught the little as the man raced into the driver's seat and drove away, passenger door open.

"Shi-chan? Spit it out." Sitting the little down he stuck his fingers as far as they would go to make the little vomit. It didn't take much, vomit spewing over the asphalt. Izaya hugged the little, who was messy, crying and drugged. "You idiot."

Rather than rescue, it felt like kidnapping. He'd taken the little to his apartment and laid him on his bed. Sure enough it was Shizuo. Easy to see without the bonnet and the pacifier. Izaya groaned. He'd likely ruined his chances with the company and he'd rescued his enemy.

It only got worse as Shizuo opened his eyes and stared at him with such vulnerability. "Daddy." The little whined. "Hot. Hurts."

Fuck. Izaya ran a hand through his hair. "You were drugged. There was bad stuff in the milk. Can you go big?"

The answer was no. The little squirming in his onesie, trying to get it off. Izaya sighed getting on the bed and tugging at the zip. He tugged the sleeves loose and rolled it down and off onto the floor. The pull-ups went next, a quick slash of his switchblade. Izaya groaned seeing the deep red silk panties underneath. "Alright, now go big. Come on, Shizu-chan. Big! Go- woah!"

Izaya cursed back pressed to the sheets, with the brute on top, big like he wanted, but also drugged and very horny. "Shizu-chan!" He snapped.

Shizuo moaned into his neck, skin hot and slick. His breathing was laboured. "Yes daddy?"

Izaya swallowed, cursing again at the friction grinding against his cock. "Shizu-chan! Get off!"

"Don't want to, daddy." Shizuo breathed against his ear. "I'm going to be a very bad boy." Shizuo kissed his neck, moving along his jaw and finally taking his lips. The kiss was chaste, Shizuo choosing to move further down, smiling mischievously as he ripped Izaya's uniform apart and latched onto his nipple.

"Shizu-chan!" Izaya hissed. Shizuo palmed his cock. "You've been drugged."

"It's hot daddy, so hot." Shizuo whined and begged. "Make it better, please."

"Shizu-chan, stop! You don't want this." Izaya sat up grabbing Shizuo's arms. His skin was hot to the touch. "Let me call Shinra."

Shizuo kissed him again, rolling his hips. "Need you to fuck me daddy. Please."

Izaya sighed. "Ask me again when you're not drugged. Lay down."

Shizuo did so watching him. Izaya folded the blanket over and over, grabbing rope from the drawer. Tying it was easy as Shizuo obeyed his commands for the most part. "Stay."

"Yes daddy."

And then he went to call Shinra.

One stomach pump and long sleep later, Shizuo woke up in his bed, head in his hands. "Oh fuck me."

Izaya sighed leaning in the chair he'd brought from the kitchen. "What were you thinking, Shizu-chan?"

"I wasn't. I'm on a timed regression."

"So why didn't you pay?" Izaya asked.

Shizuo grit his teeth. "I did. It's a damn standing order. The fucker in accounts rose the price and didn't give me a chance."

Izaya raised a brow. "Really?"

Shizuo glared at him. "I turn into a god damn kid, you think I'd leave myself vulnerable like that? I'm not the only one. That's what happens when the guy in charge of finance is a homophobic son of a bitch that loves making littles' lives miserable." Shizuo drew his knees to his chest. "The agency itself is amazing. It's a safe space and the uncle you have watching you is thorough. It's just the payment side that ruins everything."

"How did you end up with that man?"

"The guy in the booking office gave me an app." Shizuo sighed. "I'll try another agency. I can't keep running into this situation."

"This has happened before?" Izaya asked sharply. "When?"

Shizuo startled. "The payment going up. At first it was subtle, something stupid like a hundred yen over. Now the fucker puts it up by 1000 a week. My rent is half the cost I'm paying." Shizuo rubbed a hand through his hair. "Thankfully I have Kasuka to help. Funny huh. I need my brother's help so I can be his little brother."

"Self depreciation isn't you, Shizu-chan."

"Neither is me being naked." Shizuo grumbled. The thought of wearing his little space clothes made him sick. "Can I borrow a phone?"

"Why?"

Why indeed. Why did he think that Izaya wouldn't kick him when he was at his lowest. "So I can call for a change of clothes and a ride home."

"No."

Shizuo blinked. "What?"

"I said no. You're going to end up back where you were." Izaya explained. "Your agency is involved with some bad things. The gold bands contain drugs Shizu-chan. Exactly what do you think would've happened if you'd been in that car? What do you think has happened to others? Your regression is a vulnerability you can't have right now. Not out there."

Shizuo frowned. "So then what? I have my routines."

Izaya groaned. "I'll do it. Temporarily, until this case is settled. I'll be your…daddy."

Shizuo blinked, blushed and held his head in his hands. "Shit this is so embarrassing."

Izaya scoffed. "I'd say we already crossed that line. I was one of the ones feeding you."

"Kill me." Shizuo mumbled through his fingers.
