Authors note: Thanks to everyone who's reviewed, favorited, followed, or even read this story up to now! It brings me great joy to to write for you. Anyway, someone asked when I update this story; I try to update once a week between Tuesday and Thursday. I try not to clog my fan fiction dot net account with too many personal notes but if you want more details/ sooner updates/ more author engagement I suggest following me on deviant art. I'm much more familiar with how that site works. Anyway, here's the story:

o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o

Conan came back from using the restroom to find Ran sitting on the ground next to his futon. "Conan, sit with me. We need to have a little talk," she said. Conan gulped, this couldn't be good.

He made his way over and sat on top of his blankets. "What's wrong? I'm still...clean if that's what you're wondering," he said, hinting toward the pull-up he was wearing.

"No, that's not it. I mean I'm glad, but still..." she said. "Well, you've woken up wet the last couple of nights and you had an accident during a nap this morning, right?"

Conan blushed. "Y-yeah."

"So you're probably going to have another accident tonight, right?"

Conan didn't say anything. He didn't want to admit it but he knew it was true.

"So I was thinking, for bed it would be nice if you had a little more protection."

"Well yeah, I was planning on wearing these."

"No, I mean more protection than that. Something thicker," she said. Ran reached behind her and revealed the thick, folded up white diaper. Conan's jaw dropped open.

"But...but isn't that what the pull-ups are for?" Conan asked. He was tired from a long day of getting up early and doing medical tests, this was too much for him right now.

"Conan, the pull-ups aren't meant for that. They're meant for small daytime accidents. If you wear that to bed you're going to have to wake up any time you need to pee and if you accidentally...don't wake up, then I'm going to have to change you in the middle of the night," she said.

"Can't we just try one night with my pull-ups?" he pleaded.

"Think about it, you need sleep to get over this. If you wear this you can rest all you need to without having to worry about waking up. Wear the extra protection now and we'll be past this all the sooner," she reasoned.

Conan tried to think of a rebuttal but none came to mind. Getting all the sleep he wanted sounded pretty good right about now. "Okay…" he surrendered.

"Good," Ran said, smiling.

She changed Conan into his pajama shirt first then patted the pillow. "Alright, lay down," she said.

Conan hesitated but did as he was told, grimacing as his core got into position to lay back. Ran lifted up his butt slightly to slide out his pants, pulling them the rest of the way off and revealing the boy's pull-up.

Conan looked down, watching this take place. He didn't feel like a 17-year-old in a child's body, it felt to him like an out of body experience and he was just using this child's eyes. It all felt like a weird dream.

Ran grabbed the pull-up Conan was wearing but stopped and looked up to his eyes. She expected to see him crying but all she saw was a tired look transfixed on what was happening with his lower region. His eyes were half open and it looked like he'd fall asleep any moment now. She smiled, glad it wouldn't be a whole ordeal, and continued by ripping the sides of Conan's pull-up and pulling it out from under him.

Examining the pull-up in her hands she noticed that Conan had wet it just a little bit. 'How long has he been wearing it like this?' she thought. She made a mental note as she balled up the pull-up that she needed to be more vigilant and maybe check the boy every once in awhile.

Conan was slipping away. He felt his eyes getting heavy and he started nodding off. Then he remembered that he hadn't taken his pill yet and his head shot up off his pillow.

It took Ran by some surprise but she figured it was his natural modesty kicking in. "Conan please, we've been through this. Your body is nothing to be ashamed of," she said.

Conan looked at her confused for a second then realized he was laying there without pants. He reflexively covered himself with his hands and said "I know, just- can we hurry?"

Ran smiled patiently. "Just lay back, I'll be done in a second," she said.

Conan heard a loud crinkling as Ran unfolded the plastic diaper. He watched as Ran slid the diaper below his thighs and lined it up. She then grabbed his ankles with one hand and lifted them up, raising the boy's butt. Using her other hand, she pulled the diaper up under Conan's butt and all the way up to the boy's lower back. She set him down and reached back for the baby powder.

"I thought we didn't need that?" Conan mumbled, still fighting off the urge to sleep.

"Well we can't risk you getting a rash and getting even more sick, can we?"

Conan rested his head back and shut his eyes. "Diaper rash?" he groaned quietly to himself.

Ran patted the boys leg and said, "There there," before tilting the bottle and sprinkling it's contents onto Conan's privates and diaper.

The smell of baby powder filled the room. Conan couldn't explain it but it brought him a deep, deep sense of comfort. He smiled and began letting himself drift to sleep.

Ran put down the bottle of baby powder and saw Conan was content and nearly asleep so she finished up quick. She taped him up and ran a finger through the leg to make sure it was on securely. Then she stepped back and examined her work.

She'd never put a diaper on a child this large before but she thought she did alright. Conan seemed to still be smiling, which was a good sign for her. She was planning to put pajama pants on him but decided it would be best if he wasn't wearing any, in case she had to change him during the night. Besides, she thought Conan looked way too cute in just a night shirt and a diaper.

She lifted the child up a little and pulled down the blankets to put back on top of him. Ran tucked Conan in and leaned in to kiss him on the forehead.

"Ran…" Conan said in a tired, meak voice.

"What is it Conan?" Ran asked softly.

"I need to take my medicine," he said.

"Not tonight, sweetie, The Professor said to take it in the morning," Ran replied. She assumed he was talking about the medicine The Professor had given her earlier, not the medicine Conan was secretly taking.

"Okay," Conan accepted. "Good night," he said, drifting off into sleep.

"Good night, Conan. Sweet dreams," Ran whispered to him. She got up and put the baby powder away before turning off the lights and closing the door, leaving it partially open in case she needed to check on him

O-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o-o

Conan woke up a while later to an urgent need to go to the bathroom. He was glad he woke up this time but realized the reason: he'd forgotten to take his medicine.

Conan tossed off the covers and gave pause when he saw the white diaper around his waist. He vaguely remembered Ran putting a diaper on him as he drifted off to sleep. 'I was hoping I'd dreamed that,' he thought to himself. He reached down to feel it and was pleased with himself when he found it to still be dry.

Conan began to get up from bed but found the act of doing a sit-up too painful for his stomach. Instead he rolled over onto his stomach and tried to get up from there. He was able to get on his hands and knees, then he was barely able to muster up the strength to rise the rest of the way.

Now standing, he stopped and regained himself. The sharp pain in his gut served as a stark reminder that he needed to take the pill ASAP, but considering the size of the pill he'd first need to get a cup of water to wash it down.

Conan made his way to the slightly ajar door and stopped when the hall light hit him. He looked down, now acutely aware he wasn't wearing pants. He sighed, then pushed the door all the way open. He hoped Ran was already asleep but it couldn't be helped.

Conan walked down the hall. He noticed a very distinct crinkling with each step he took, unmuffled by any outer wear. He didn't want Ran to hear him so he tried to move quietly. He found that not pushing his legs together and moving slowly did the trick. So with that Conan waddled down to the kitchen with a deliberate speed.

As he waddled he considered the diaper. It was so much thicker than the pull-up he'd been wearing all day. Plus it rode up to his stomach. He was mostly able to ignore the pull-up and forget it was there but the diaper, wiggling back and forth on his butt and pushing his legs apart, was an unforgettable presence.

Conan got to the kitchen. He grabbed a cup from the drying rack near the sink, being unable to reach the cabinet, and pushed the lip of the cup to the water dispenser on the fridge. As water began streaming into his cup he remembered what woke him up in the first place: he needed to pee!

'Crap, how did I forget?' Conan scolded himself, tightening his bladder muscles. The cup got fuller and fuller, making the sounds of trickling water deeper and deeper. The urge became overbearing and Conan used the tried and true method of crossing his legs. He found it was no use, the padding was too cushiony on his thighs to help dam the flow. He tried holding himself with his free hand, again finding the padding too soft and thick for it to help any.

Conan felt a small spurt come out of him so he doubled down on his bladder muscles to stop it. He began to panic and it seemed the sound of trickling water was so much louder now. He felt another spurt, then another. Then a long continuous stream.

Conan stood at the fridge, listening to the running water as his bladder involuntarily emptied itself into the absorbent diaper. Worry turned to relief as the pressure on his bladder gushed out of him and turned into a comforting warmth around his groin. Conan stopped resisting completely, the padding swelling up between his legs and near to his behind.

Conan was completely lost in thought, concentrating on his emptying bladder. As he was nearly finished going Ran's voice snapped him out of it. "Conan, what are you doing?!"

Conan came too and looked back at Ran, then toward the cup he was holding. It had overrun with water and was spilling into the drip tray and onto the floor in front of the fridge, making a sizeable puddle. He yanked the cup away, stopping the stream.

Ran grabbed a towel and moved toward the puddle to wipe it up. "What happened?" she asked, hurrying to get to it before it spread too much.

"An accident…" Conan replied, timid and confused.

Ran knelt in front of the fridge and started drying up the water. "I'm sure it was an accident but why didn't you pull the cup away after it started spilling?" she asked.

When Conan said nothing Ran looked at the child and saw what Conan meant by "accident." She turned her head and was eye level with Conan's diaper. It was clearly larger than when she put it on and now with a yellow hue.

"Oh...I see," she said. "Did you not have to go before you started getting water?" Ran was slightly annoyed, she'd nearly drifted off to sleep before she was interrupted by the sounds of splashing liquid.

Conan turned away, not wanting to present his shame to her. "I forgot…" he said quietly, then added, "I'm sorry."

Ran put a hand on Conan's shoulder. "It's okay. That's what the diaper is for," she said. "Now go back upstairs, I'll finish cleaning up here then get you ready for bed again."

Conan sheepishly nodded and made his way back to his room with his glass of water. The crinkling was quieter now but he still waddled as he walked, now more out of necessity since his diaper being wet made it swell up and push his legs further apart. The comforting, warm sensation was quickly fading and being replaced with a clammy, wet feeling. He counted himself lucky he'd accidentally woken Ran, he didn't want to sleep in this wet thing.

Conan chided himself the entire way. 'How could I forget how badly I needed to pee?' he wondered. He decided it must be because he'd been managing the frequent, sudden urge to pee all day. Letting one time slip through the cracks was bound to happen.

Conan got to his room and slid the door partially closed. He quickly grabbed the hidden pill bottle and swallowed one of the oversized pills, using the water as lubricant to help it go down. He stashed the bottle back and sat on top of his futon.

A moment later Ran entered and got to work. The changing went the same as before but this time Conan was more awake. When he wasn't trying to cover his privates he was covering his eyes in embarrassment, especially as Ran wiped him clean.

Ran waited until the boy was in a dry diaper and taped up before scolding him. She didn't want him to associate a wet diaper with any more negative feelings than it already brought.

"Now Conan," she said in a firm voice, "if you need anything come get me or just yell. You're sick, you don't need to be getting up and down all night."

"Yes, Ran," Conan said diligently.

Ran lifted the boy slightly and was preparing to tuck him in when he interrupted her, saying, "Can I ask for one more favor?"

"What is it?" she asked.

"Can I wear pants?" he asked, bashfully, looking down at his bare legs and exposed diaper.

Ran thought for a second but couldn't see a good reason to deny the request. She smiled and slid some pajama bottoms on him before tucking him in and wishing him goodnight. As she left the room she spotted the cup of water Conan had brought up with him, now completely empty. She sighed. If he was thirsty then that couldn't be helped but she thought he might regret drinking so much when he woke up the next morning.
