Ciel pursed his lips. "That's… not good."

Sebastian frowned. "I suppose not, me being a servant."

"And a demon," Ciel added, sighing. "Alpha servants end up mating with their omega lords and ladies frequently, and vice versa. It shouldn't really be a huge problem. It's not as if the Phantomhive house is crumbling, so there's no real need for me to mate with a noble other than maintaining status."

Sebastian raised an eyebrow—he was thinking very clearly for someone in his first heat. He scooped up some of the 'slick' leaking from Ciel and licked his fingers, letting out a light chuckle. "Young master, may I ask why you have deceived me?"

"You don't need to call me that anymore, I imagine." He said, dodging the question.

Sebastian leaned close to his mate, pulling out of him and crawling onto the bed to cradle him. "If you wanted me to make love to you, you could have asked. There was no reason to fake a heat." He whispered into his ear, rubbing the oil around his stretched entrance.

"I… I don't know what you're talking about." Ciel huffed, blushing and looking away.

"I thought that you were a bit young to be in heat. But may I ask, where did you get the pheromones?"

"I bought them from a vendor in London, last week," He grumbled. "While you and Finny were picking up the flowers for the garden. A man was selling pheromones, that's what gave me the idea."

"Well-played, my lord." Sebastian snickered, kissing the younger male's forehead. "But you haven't answered my question. Why did you find it necessary to put on such a show?"

Ciel smirked. "It would have been no fun if I'd simply told you to fuck me one day. I figured it'd be more interesting to make a game of it. A challenge, even. I'm not surprised you saw through my act, though."

Sebastian laughed. "You never cease to amaze me, young master."

"I told you that you didn't need to call me that."

Sebastian grinned slightly. "Very well, Ciel."

Ciel felt the color drain from his face, hearing his demon say his name for the first time. The way he put emphasis on it was frightening, but also extremely exciting. Suddenly, a thought occurred to him. "Sebastian… Are you still going to eat my soul?"

"Yes." Sebastian answered without hesitation. "We've come too far to back out now."

"But… We're mated now." Ciel mumbled. "Don't you want to cherish me, and protect me?"

"Most certainly." The demon agreed, wrapping his arms around the boy tightly to prove his point. "You and I will be together for eternity. After all, I will only be devouring your soul."

"You… you bastard!" Ciel gasped, realizing what he was saying. "All this time, you let me think I was going to die!" He leapt out of bed angrily as Sebastian tried to contain his amusement. "Why didn't you tell me?"

"Those unwilling to die for revenge aren't worthy to become demons." He explained. "Therefore, it's usually kept a secret that a human that has its soul eaten becomes a demon. There are many humans who would gladly give up their soul for eternal life."

"But you need to make sure they're ruthless enough to be good demons." Ciel scoffed. "Well-played, butler." He mocked.
