I do not own Kuroshitsuji. Also, this chapter contains spanking, and I will NOT tell you from what part it begins and when it ends because it's a pretty important part of this chapter. It's not very graphic, but if you don't like it, you can skip this chapter. At some time, you'll think that it will turn out to be yaoi, but I promise it won't. Enjoy!

Ciel shot up from his bed, hissed from the pain on his back and fell back down again.

"Wh-Where did…"

Sebastian looked at his master with fake curiosity on his face, while he was walking towards him. "Where did what?"

Ciel looked at him like he just now realized that he was in there. "N-Nothing!" he tried to cover it up, even if he had the feeling that Sebastian already knew about what happened at the night.

Ciel mentally slapped himself when he realized that Sebastian most probably already knew about his accident. But of course he knew! He was a demon! Ciel should have realized earlier that there was nothing he could hide from Sebastian.

And after all, the sheets most probably didn't vanished by themselves.

The butler helped his master get on a sitting position and brought him the disk with his breakfast. "I see," he said. "Are you going to pretend that your back doesn't hurt again or shall we write that letter?"

Ciel felt his cheeks becoming red. "We can write it later."

The butler's smirk got wider. "As you wish, My Lord, as long as we write it today."

Ciel nodded, refusing to reply. Instead, he slowly began eating his breakfast.

He slowly sipped down his morning tea. Earl Grey, his favorite. And for some weird reason, even if he had emptied his bladder through the night, he felt for once again like he needed to use the loo. And quite bad, actually.

He raised his head and looked at Sebastian, who was now opening the curtains, but looked back down at his plate before he had the chance to meet his eyes. His night accident was too embarrassing for him, and now that he was almost sure that Sebastian knew about it… he couldn't bear to look at him in the eyes.

Ciel felt his stomach protest. Also, his night accident was too exhausting. He dig in his food and swallowed down his eggs before he even had the time to realize it.

"Oh my," he heard Sebastian's voice, but didn't raise his head to look at him in the eyes. "Someone was hungry. Did you do anything tiresome during the night?"

Ciel felt his cheeks becoming red. He could actually hear the smirk in his butler's voice. "Shut up."

Sebastian laughed, but didn't continue. Oh, he loved teasing his master!

Ciel gave him the disk that previously had his breakfast on, without making eye-contact, of course. When the butler came back, he helped his master dress up. This had to be one of the most difficult parts of all, while Ciel was trying not to make eye-contact and Sebastian was trying to dress him up properly.

"Young Master, please stop moving around! I'm trying to button your shirt!"

Ciel kept his mouth (and his eyes) shut, and let the butler do his job. He had started feeling quite uncomfortable, and not because Sebastian was touching him, nor because his back ached like there was no tomorrow. He felt uncomfortable… down… somewhere before his sensitive part… again.

Five minutes later, while Sebastian put his nightshirt away, Ciel threw his feet off the bed and tried to get up without the butler noticing. He failed at both parts.

He fell down before he had the chance to stand normally on his feet, and the sound he made, made Sebastian turn around and look at him. The smirk on his face disappeared for a couple of seconds and worry took it's place, but then it came back.

"Does Young Master need help to get up?" Sebastian said in a mocking voice. Those words made tears come to Ciel's eyes, but he didn't let them flow. He didn't want to be teased. He didn't want to be considered as 'little', and most certainly, he didn't want anyone, anyone, think that he needed help.

"No. I don't need your help," Ciel said, using a much more aggressive tone than what he should. Sebastian was surprised, but finally understood that his master may be in much more need for his help than what he thought.

Sebastian sighed as he saw the kid struggling to get up, and a little bit latter, he went close to him and helped him get up. He didn't say a single word while doing so, and (for once!) he wasn't smirking.

"Hm!" Ciel said, but didn't protest.

"Do you want me to help you to go to the loo?

"No! I-I c-cant do i-it!"

Sebastian looked at him suspiciously. "Are you sure?"

"Yes, I-I am! Now leave me alone!"

Sebastian didn't believe him, but did as he said.

Right when the door closed, Ciel moved his hand to his crotch, just like a little kid. He hated what he was doing, but he couldn't do anything else. It really hurt!

But he knew that Sebastian would be back in less than five minutes, so he didn't have time to go to the loo. When Sebastian came back, they would instantly write the letter to the doctor.

Ciel didn't want to go to the doctor!

He slowly walked to the door. He went slowly not only because he didn't want to make any noise, but because his back (and his bladder) prevented him from going any faster. He cautiously peeked out of the door, and when he got sure that no one else was there, he got out.

He heard footsteps on the hall, so he run and opened the first door he found and got in. The speed made him leak a little, but at that moment, he didn't care. He didn't shut the door completely, but let it an inch open, so he would be able to see outside.

He saw Sebastian getting into his room, and a minute later getting out again. When he got sure that he was away enough, he run out of the room he was in and got back to his own room.

Another little spurt came out, but he couldn't help it. He went towards the bathroom's door, but when he tried to open it, he realized that he couldn't. He needed to put more strength, and at that moment, he couldn't.

He heard footsteps at the hall again, but this time he didn't do anything to hide himself. Instead, he turned around, so whoever got in the room would be able to see him completely.

It was Sebastian who got into the room, and by seeing his face, as if it was programmed, that exact moment Ciel's bladder gave in.

"My Lord, I finally found- What is going on?" he asked with surprise when he saw the darkening spot on his master's pants. When those words got out of his mouth, Ciel burst into tears. He cried with sobs, but not a single word came out of his mouth.

Sebastian watched with rapture the whole time. But inside of him there was boiling anger, which was waiting for Ciel to get finished to burst.

Ciel peed for three minutes straight before the flow started getting slower. And even when he completely stopped, he was too scared to look at Sebastian. The butler was the first one to talk.

"Young Master, come here."

The words came out of his mouth slowly, with a creepy tone. Ciel thought it would be better if he listened to him, and started to slowly walk towards the demon. When he reached him, Sebastian, much to Ciel's surprise, started removing the kid's clothes. He didn't even bothered to wipe off his tears this time.

"What are you doing?" Ciel yelled, and for the first time that day, he tried to make eye contact with the demon. But this time, it was Sebastian who refused to look at him.

"My Lord, you definitely need to change clothes. Those got dirty."

Ciel got confused, but didn't say anything.

Sebastian's delicate hands unbuttoned the child's clothes and didn't stop until he was standing completely naked in front of him. Sebastian walked towards the drawer, careful not to step on the (pretty big) puddle of pee on the floor. He took out another pair of clothes for the kid, but instead of dressing him instantly, he left them on his bed.

"I think that now that you are already undressed, we shouldn't miss this chance."

Ciel's eyes opened wide from the shock. "W-What are you talking a-about?"

Sebastian sat on Ciel's bed and motioned to the kid to come closer. And so he did, with careful, small steps.

"Sit" Sebastian ordered, and with his left hand hit his left thigh, meaning for Ciel to sit there.

Ciel gulped nervously, but did what he was told, with his back leaning on Sebastian's chest. With a quick move, before Ciel had the time to realize it, Sebastian brought him over his knee.

"You have crossed the line, Young Master. Lying and lying, hiding your pain even if everyone told you that you shouldn't… that's enough."

Sebastian raised his hand in the air and let it loudly fell on Ciel's bum.

SMACK!

Ciel hold himself on Sebastian's trousers. "Wh-What a-are y-you d-doing?"

SMACK! SMACK!

"S-Sebastian! Stop this right now!"

It was really hard for Ciel to hold back his tears now.

SMACK!

"Sebastian! This is an order!"

SMACK! SMACK!

"S-Seba-astian!"

A couple of tears rolled down his cheeks.

SMACK! SMACK! SMACK!

"S-Sebastian please! I-It hurts!" Ciel said.

SMACK!

"Tell me, Young Master," Sebastian said while landing his hand on Ciel's bottom a couple of times more. "Why are we doing this?"

SMACK! SMACK!

Ciel gulped and tried to talk, with tears running down his face full-force.

"B-Bec-cause I-I-I w-we-et m-mys-sel-lf."

Sebastian's hand stopped midair from the shock. He could feel the kid's tears soaking his pants.

"What the- No, no, no, Young Master," Sebastian said, and with a quick move he brought him to a sitting position, with his legs open with the demon's legs between them, face to face with each other.

Well, at least it would be face o face if the kid finally decided to look at him. Because Sebastian knew that this wasn't going to happen, he took the kid's face to his hands and pushed it upwards. Not much, but enough for his eyes to meet his own eyes.

"Young Master, this wasn't because you wet yourself!"

"T-Then wha-at?" Ciel sobbed.

"I told you before," Sebastian said in a caring tone, but Ciel refused to believe him. "This is because you lied to me, again and again, and hide your pain even if it was unbearable, and not asking for help, even if you are in need of it."

Ciel thought of what the demon said for a moment, and without saying anything for once again, he pushed away the demon's hand that was holding his head up, and the one that prevented him of falling down. Then he tried to get up, but the demon caught him again before he had the chance to move.

Tears were still falling down on his cheeks, but for the first time that day, he willingly looked into Sebastian's eyes.

Sebastian pushed the kid's head on his chest and let him cry there, until (fifteen minutes later) he fell asleep. He moved him and put him on his bed, but when he saw the boy wincing, he realized that he shouldn't have put him lay on his back, and on his sore bottom.
