Summary: After refusing to be purified Sebastian becomes even more attracted to that soul; eating him would be a waste. Oocness BDSM

King Of Hell

"Young master I was very pleased with the way you acted today." Sebastian said buttoning Ciel's white night shirt. The child sat on his bed with the adult kneeing on the floor.

"It's not your place to have an opinion like that, Sebastian. It doesn't matter if you're pleased or not I shall act the way I want to." The boy glared.

"I know how rude, forgive me young master." The young kid laid on his back allowing the demon pulling the covers up to his chin.

"You are forgiven."

"I'm glad for your kindness. Please allow me to stay by your side forever." The devil placed his right hand over his heart.

"Only if you are loyal to me and only me."

"I am loyal only to you." He repeated grinning. The devil sat on the edge of the bed scooting closer and closer to the earl.

"Stay the night with me that's an order."

"Yes, my lord." Blue eyes closed trying to entering a night of bloody dreams. True to his word Sebastian didn't move from that bed. He leaned over taking a little breath and blowing out the candelabra. With his jacket folded neatly at the end of the bed the demon laid next to his master running his fingers through the soft tresses. Leaning in the butler's face was close to the back of Ciel's head.

He could smell the sweet chocolaty scent of his lord. "So good." His tongue slide out of his mouth touching the shell of Ciel's ear.

"Sebastian?" The lord's voice was groggy. "Why are you licking your master's ear?"

"I'm sorry, I thought you were asleep." He gave one last lick to the ear moving away giving respectable space.

"Well I don't believe I told you to stop." The demon grinned his lips returning to suck on the earlobe.

"Do you want me to touch you, my lord?"

"Che as if. I wont ever beg; especially for something like your touch."

"Well, I want to touch you. Will you let me?"

The earl had to pause for a moment of thought. "I guess, servant."

"Thank you." From behind he hugged his sire. "I have a proposition for you." The devil kissed the child's neck when the boy didn't respond he began to speak. "As I said I was very impressed by your actions today. I have lost many to an angle's purification, you've been the first to resist. So my proposition is this, let's not waste that soul you have. Ciel Phantomhive my master would make a fine demon. Let me teach you the demon ways together we can be an unstoppable powerful duo."

"So it will be you and me forever tormenting others and causing the deaths of millions?"

"Pretty much."

"What happens if I say no?"

"Then I'll eat you just like in the contract. I just figured-"

"I accept." He agreed without hesitation. "I want you to keep your promise to me. Never betray me or leave my side." Cerulean eyes closed as the ruby eyed male kissed his neck once more.

"I shall never leave you and I shall never betray you." The monster repeated once more. "Even though I don't get your soul I still get your humanity that's excellent on its own." The taller male molded his body into the child's letting the boy feel his growing erection. "Now, I must ask again do you wish to become a demon? You can't take it back and the changing process is not fun."

"I'm not scared."

"That's my young master." The demon dug his bare claws into the front of the night shirt. He pulled the seams apart the buttons popping off. Ciel wanted to yell at his butler for ripping his favorite nightwear but decided against it knowing it would have a bad result.

He pinned the delectable heir below him needing to feel the squirms he gave his lord. The servant's hands roamed everywhere caressing the soft skin of his chest and stomach. The aristocrat cried out in pain when the adult bit his nipple.

Red liquid was drawn from that nipple. It hurt a lot but it also felt good. Sebastian's tongue smeared the blood everywhere enjoying its metallic taste. He gathered some blood in his mouth wanted the boy to taste himself.

They kissed passionately the body fluid leaked out of the corner of his mouth. Currently the human didn't like the taste of blood well, at least not his own. Scraping at the black suit Ciel wanted to return the action. Smiling into the kiss the domestic helper helped strip them both of their remaining clothes.

Sweet virgin flesh; the touch the scent. Enticing. Delightful and delicious.

Sebastian want more and frankly so did Ciel. The demon pressed his nude body against his master's giving the boy a taste of his silky smooth skin. He began to bite lower leaving red marks all over. The demonic being wanted to mark the boy as his but he had no right. However, when the sire turned into a demon his mark shall always be there; the mark that Sebastian had done the job and no one else.

Ciel was strangely aroused his servant touches sending him into a natural high. The soft mews the boy gave were unbearable the fiend's own body reacting in a uncontrollable way. "Are you ready?"

"Do it." Without any sort of lubrication the monster had entered his sire. Allowing the child to get use to his length before ripping him opened. "Move." The nobleman commanded though the pain had not left his small body.

They had set up a suitable rhythm the demon getting ready for the ceremony. It was simple to perform, so he wasn't worried about any side effects that could happen. Leaning down he kissed his contractor savoring his lips. "I'm close Sebastian."

"As am I, get ready." The demon moved harder against the smaller body. Ciel's legs wrapped around his waist pressing into the harder body wanted his member to go deeper.

The crimson eyed male bit into the boy's neck injecting his poison. His black claws scraped the skin of his back drawing more blood.

The earl just held onto the devil for dear life making his back drip red. The bed sheets were stained with blood not that either of them seemed to mind. He licked at the wound he made before pulling away from the child. His saliva clogged the hole stopping the flow.

The aristocrat rolled into the fetal position letting out a scream. The nude boy was wrapped in the dirty sheet and held tightly by the scarlet eyed male. Ciel screamed even louder, his body felt like it was on fire.

"S-Sebastian! W-what's h-hap-pening?"

"The change has begun you shall be full demon shortly." Everything is changing inside and out; the demon's powerful poison flushing out everything that was human about him. The only thing Sebastian wondered was if he used to much or not enough poison. Ciel started to growl in pain.

The Phantomhive blood immediately grew about half a foot his bones and muscles stretching like crazy. His skin turned paler his hair was longer and darker. His nails also became longer matching Sebastian's in color. The contract on his eye was now gone that orb was a bright bloodshot red while the other eye was still blue. His organs were strong now; his pathetic human immune system was replaced by a stronger demon one.

"It hurts, Sebastian."

"I know, young master."

"What did you do to me?"

"I injected you with my poison."

"Poison?"

"Every demon has their own poison in their teeth. The substance ranges from good to bad. Meaning it can kill or even act like an aphrodisiac." He looked at his master's expression. "Nothing bad will happen to you under my watch. Perhaps you would you like something to drink?"

Ciel didn't answer back. "Wait here." He said like his sire could move from that bed. Room temperature water was served to him. Anything hot or cold would hurt his new developing fangs. Sebastian held the glass to his lord's lips; the water entered his mouth but Ciel had spit it out instantly. The master was no longer able to eat for the next few days. Ciel's taste buds had changed he no longer craved sweets or liked to drink tea. New demons usually ingested blood from the demon who had changed them.

The heir began clawing at the wall trying to create new pain to knock out the inhuman pain he's feeling. The throbbing in his body was now because of the poison he's making. A loud growl escaped through his lips.

Sebastian laid on his back pulling his master to his chest; his shirt was ripped off. Unconsciously the earl licked his lips leaning down to lick his butler's nipple. Biting down making blood flowed from the tip. The servant moaned as Ciel lapped at the kernel of flesh.

The last blue eye just turned red from his first blood meal. Smirking the adult ran his finger through the soft black locks. The small wound closed quickly enough making Ciel rather angry. Annoyed his bit the other nub making more red liquid gushed out. "Don't make yourself sick."

"You better not be telling me what to do. I'm still the master here." The new demon sneered.

"It's good to see that even when you're sore you're still yourself."

"How long will it last?"

"It depends on the person. In your case maybe a few days."

"A few days?"

"Do you regret the decision now?" He asked with a hint of sadness.

"No." Sebastian smiled and kissed his lord holing him tightly. "Again?"

"If my lord permits it. Maybe it will even make you forget the pain your in." The older demon said suggestively.

"Fine, but no biting!"


A/N: I'm not into BDSM I guess that's why I'm trying it out. "Don't knock it till you try it" thing I'm going to try to do a lot of sadism anyway if you want more you have to review with encouragement. Ciel will be on top soon. X]
