I do not own Kuroshitsuji.

Thanks for all of your reviews! And also, I was wondering how you would like it if I put a spanking scene in the story.

Ciel was bored. Again.

And he was in pain. Again.

Yet he had a bunch of paperwork to do. Again.

He continued signing the papers, even if every single minute that passed, his back hurt even more.

At some moment, he decided to stretch a little, hoping that this would relieve some of the pain. Instead of what he hoped, his back made a very loud "CRACK!", making Ciel get back to his previous position, hissing and swearing under his breath with words that if Sebastian heard him saying, he would have it really bad.

Even if Ciel decided to get back to his work after that, he couldn't concentrate at all. And, for some reason, he felt relieved when Sebastian decided to get in his office.

"Young Master," Sebastian said. "For when do you want me to make an appointment with the doctor for your back?"

Ciel changed his mind. He was better without him.

"Never!" he shouted, both too loud and too fast.

Sebastian raised an eyebrow. "Hmm, Young Master seems moody today… or is it just his back that hurts?"

"It's better now," Ciel said, looking at the ground instead of Sebastian. He knew that it wasn't going to work, especially if you consider that a couple of hours earlier Sebastian was helping him to get off of his bed.

"I don't think so, Young Master. Please tell me when I should arrange our appointment with the doctor."

"I am telling you that you don't need to, because I'm fine."

Ciel was trying to keep his voice still. The demon always knew when he was lying, and it would be better if he didn't have enough hints.

Yet there was almost no possibility that this time he would fail.

Almost no possibility.

"And I am telling you I don't believe you. Now tell me for when you want me to make the appointment, or else I will arrange it by myself for tomorrow, if not today."

No possibility.

Ciel gulped. He would make another effort to persuade Sebastian that his lie was true.

And if he doesn't believe me again, I'll tell him to make the appointment for the next month, or the next year or something. Or maybe for the 30th of February.

He knew that the demon wouldn't believe him for once again, but what did he have to lose?

Ciel sighed to pretend he was irritated. "You don't need to make an appointment! My back is fine!"

Now it was Sebastian's turn to sigh. "Then let's make a deal. If you show any sign that your back hurts until the end of the day, then I will arrange our appointment with the doctor for the right next day. If you don't, then I will never speak about this again (unless if you want me to, of course), and we will go to the doctor only if you want us to. Alright?"

Ciel looked at him suspiciously. "Only until the end of the day?"

Sebastian nodded.

"And how can I know that you'll keep your promise? What if you are lying?"

Sebastian smirked. "I never lie."

Sebastian left his master's office smirking. There was no way he could make it until the end of the day without showing any sign that his back hurt.

The butler's smirk became bigger. Oh, he loved seeing the other side of his master, so sensitive and fragile…

Just like a child.

Suddenly, Sebastian felt a hint of guiltiness. What if Ciel won?

He remembered the doctor's order. "You should put the health of your master first", or something like that. Maybe this was the only order, except his master's, that he should follow.

But no. Ciel was going to lose. And if he seemed that he wasn't going to, then Sebastian could play a little trick on him.

After all, he was a demon. He was able to cheat.

Only when Sebastian left his office, Ciel noticed that he couldn't even get up from his chair.

He was planning to get up and walk around a bit, and then try to stretch a little. But when he tried to get up, he fell back down breathing heavily, trying not to yell from pain.

But he wouldn't give up!

He couldn't give up…

Ciel put his hands on the desk and pushed as hard and at the same time as slow as he could. For a bit he thought that maybe he could make it, but then his back cracked loudly, making him fall back down again.

When he got sure that there was no possibility that he would get up, he started planning what he should do.

He decided to stay the whole day on the chair, pretending that he was busy. He would ask Sebastian to bring him his lunch and dinner there, and at night he would fall asleep (or at least pretend to have fallen asleep) on the chair. The demon would carry him to his bed.

But there was a little problem.

Ciel felt a small, tiny but still existing pressure on his bladder.

And even if it was tiny, it was still morning, meaning that until the night it would be unbearable.

Or non-existing. But then an accident would be existing.

And now he had to choose: the doctor or the accident?

He didn't want any of them. Right that moment, all he wanted was…

"Sebastian!"

Ciel covered his mouth with his hands. He didn't mean to say that!

In seconds, the butler was there.

"What do you need, My Lord?"

Ciel gulped. What should he say?

"I-I… I want you to make me some tea!"

This was the first idea that came to his mind, and most probably not the best one. Right that moment, he should not drink anything if he wanted to 'survive' until the night.

Sebastian bowed and then left. He came back with Ciel's tea, and refused to leave until he had drunk it all. He didn't say something, of course, but Ciel took some quick glances at him and saw that he wasn't going to leave until he was finished.

So he did. And just as he thought, Sebastian left right when he returned him the cup.

At lunch time, he told him to bring his food there, because he was 'busy'. He couldn't eat that much though, as the growing pressure on his bladder prevented him from doing so.

He sat there until about six in the afternoon, when Sebastian brought him the afternoon tea.

"My Lord, I am going to leave for the afternoon, because even if I told Finnian exactly what to buy, he brought many wrong things, and ruined everything that was right. So I will most probably not be here for the whole afternoon."

Ciel nodded, mostly thinking about his little 'problem' instead of what Sebastian said. Right that moment, he really wanted Sebastian to leave the room, so he could squirm as much as he wanted on his chair.

When Sebastian left, Ciel crossed his legs and put his hands on his crotch. He tried to plan what he should do next, and how he would manage to get through the day without an accident, but then he realized: he couldn't.

But then thought came to his mind: he could ask help from the other house stuff.

Not Meyrin. Even if she was a good choice, she still was a girl. She would not understand, and she would most probably tell Sebastian.

Not Bard. Just… no. To be honest, if Ciel despised someone of the Phantomhive Household, that was the cook. All of his swearing and stuff… just no.

Tanaka wouldn't even understand what was going on. He would most probably just keep saying "Ho ho ho" like Santa Clause and drink tea.

So what was left?

Finny.

But Finny was so… innocent, like a child, and Ciel didn't want to ask him to help him for something like… this.

Ciel squirmed on his chair, putting his second hand on his crotch to hold better.

No, not Finny. Finny sometimes was unpredictable, and something like this could turn out with him worse than what would do with Bard.

So there was only one option left.

He would wait for Sebastian to come back, and then tell him everything. Right that moment, he didn't care about the doctor, he didn't care about Sebastian winning the deal they had, he didn't care if it would be embarrassing… he just wanted to pee.

Really, really bad.

So he waited. And waited. And waited. Every minute that passed was torturing, and until Sebastian came back, Ciel had reached the point where he knew that, even if he could get up, he wouldn't be able to do so, because if he did, he would lose it all.

At some point he even started crying. It was unbearable! And the fact that he was crying made him disgusted of himself. He shouldn't cry! He wasn't a baby or something!

He was Ciel Phantomhive!

But a little bit later he decided that he shouldn't care about that either. There were more important matters to think.

For example, the fact that he had already lost about two big spurts and four small ones.

It was almost night when Sebastian came back. When he got into Ciel's office, he begun saying something like "My Lord, why are you still here?" but stopped in the middle of it when he saw Ciel's tear streaked face. He left the bags he was holding on the floor and ran at Ciel. He kneeled at the ground next to his chair and took Ciel's face to his hands.

"My Lord, why are you crying? What is the problem?" he asked in a worried tone.

"It hurts," Ciel whispered, not giving any more explanation, even if he knew that he would need to do so sooner or later.

"What hurts?" asked Sebastian, now even more worried. "Is it your back again?"

Ciel shook his head no, and Sebastian was going to ask again, but then Ciel lost another spurt. Sebastian could now smell the urine in his pants.

Not again! Thought Sebastian for a moment, but then he got angry at himself for even thinking that. Sometimes he needed to remind to himself what he had told to the young earl: Ciel was just a kid. Sometimes he wouldn't be able to control himself, and that was normal.

Sebastian, without any further explanation, took the crying child in his arms. But by thinking, Sebastian had lost many important seconds. And Ciel, even I that moment he could hardly breath, he was able to think that he didn't want to pee on Sebastian again.

Even if Sebastian had already started walking to the nearest bathroom, Ciel knew that he wasn't going to make it until there. He pushed Sebastian away with all of his strength, making the shocked butler relax his hands and let him fall down on the floor.

He fell on his back, and the pain made the young earl yell and loose total control. Not that if he didn't he would be able to hold it for much longer.

Sebastian looked at the kid shocked, as he kept peeing on the floor. He soaked his clothes, the carpet, and made a pool so big that reached Sebastian's shoes, even if he was standing far away from him. Sebastian took a step back so he wouldn't get his shoes dirty, even if he knew that he should do so in a little while. To be exact, right when Ciel stopped peeing.

Ciel kept peeing for four minutes straight, leaving Sebastian shocked. How could such a little kid hold so much liquid inside of him?

When Ciel finally finished, Sebastian stopped caring about his shoes and walked towards the kid. He took the now even more crying child into his arms and took him to his room, not forgetting to lock the door of the office, so no one would get in to see the mess the young earl had made, and careful that no one would see them.

He quickly changed the earl's clothes, putting his in his nightshirt instead o normal clothes.

Then, he sat on Ciel's bed, holding him on his arms. The kid put his head on Sebastian's shirt and cried for ten minutes straight, with the butler comforting him.

When the boy started calming down, Sebastian looked at his face.

"Well?" Sebastian asked.

"W-Well wh-what?"

"Care to explain me what happened?"

Ciel gulped, knowing that Sebastian had won.

"M-My b-back…"

Those two words were enough for Sebastian to understand everything.

"I see…" he murmured, and then raised his voice. "Tomorrow morning we will arrange our meeting with the doctor, whatever you say."

Ciel nodded, not in the mood to protest.

"My my, after sitting all day on that chair, your back must be awful."

Ciel nodded again, and this time Sebastian did not continue, seeing how tired the kid must be. They sat there for some more minutes, until the kid finally fell asleep.

Sebastian tucked him in his bed and looked at him worried. He probably was in much pain as he didn't get up even if he wanted to pee so much.

Well, maybe he should really let him sleep as much as he wanted the next day.
