Ciel sat bolt upright, sides heaving. The room around him was pitch black. He had had the same nightmare for two weeks now, and couldn't understand why. His sweat-soaked nightshirt clung to his small frame, and he desperately tried to calm his breathing. Just then, there was a light knock on the door, and Sebastian entered. "Young master, are you alright?" he asked, seeming worried. Then again, thought Ciel, he is a demon. I thought demons couldn't feel compassion, worry, sorrow or love. Ciel tried to get his tired brain in order.

"Yes, Sebastian. I am perfectly fine." Ciel tried to feign composure, but Sebastian saw right through him.

"Did you have a nightmare again, young master?" Ciel gave in and nodded. "The same one?" Another nod.

"I don't understand why I'm having these," Ciel said.

"Perhaps I can help you dissipate the memories of the nightmare," Sebastian said, taking a few steps closer.

Switch to Sebastian's thoughts

I can't stop them. These feelings. Is this what it's like… to love? To want after a body for a purpose other than the beautiful soul housed inside? He felt his canines sharpen, and his eyes flashed a soft pink in the dark room, with slit pupils. I won't be able to hold back this time. He thought of all the times he's had to hold back. To hold back from caressing his young master, to hold back from brushing that soft hair away from his face. Not any longer, he thought. After tonight, the young master will be mine alone.

Switch out of Sebastian's thoughts.

"How will yo-" Ciel started, but was cut off when Sebastian abruptly closed the distance between them, cupped his face in his hands, and kissed him.

Ciel immediately froze. This can't be happening, he thought. Why?

Sebastian toyed with his mouth, moving his lips against Ciel's in such a way that Ciel groaned softly, slightly opening his mouth. He immediately realized that this was a bad idea, but before he could stop Sebastian, the demon slid his tongue inside Ciel's mouth. He explored every inch of Ciel's moist cavern, claiming it as his. Ciel, pressed against Sebastian and not being able to do a thing, gave in and hesitantly started to copy Sebastian's movements. Sebastian smirked when he felt Ciel's small tongue trying to grapple with his, and deepened the kiss, tilting his head to the side. Sebastian moved his hands from Ciel's face and started moving them along his back, smoothing and caressing the muscles. Ciel groaned again, and Sebastian lifted the shirt that was still slightly wet from Ciel's sweat off of his body, breaking the kiss.

Ciel almost fell backwards, but one of Sebastian's strong arms was wrapped around his waist. The other hand tossed the now-useless shirt to somewhere in the room. Sebastian decided it was a good time to take off his gloves, and slowly, teasingly, used his teeth to pull the fingers loose and take them off, discarding first one glove, then the other. Sebastian started to kiss around Ciel's collarbone, finding that sweet spot and sucking on it, which made Ciel's breath hitch. His hands moved down the boy's chest, tweaking his nipples and causing Ciel to moan.

Sebastian moved his mouth down, and kissed the area around his right nipple, then kissed the nipple and sucked. Ciel continued to moan, and Sebastian eventually switched to the other nipple, giving it the same attention. Ciel, trying to regain some sense of leadership, started to pull off Sebastian's butler clothes. Sebastian stopped his ministrations to help him, and soon Sebastian was left without any shirt on. Ciel sucked in an appreciative breath at Sebastian's amazing muscles, and Sebastian smirked. Tired of sitting, Sebastian picked up Ciel slightly and laid him out on the bed, then gently lay on top of him, using his arms to hold himself slightly off of Ciel's body. He once again pulled his young master into a kiss, and then, with another smirk, started rubbing his hips in a circle on Ciel's.

Ciel gasped, and melted into the kiss, not being able to do anything else. Sebastian's hands roamed his body, and travelled down his chest to the hem of his pants. Ciel's breath caught, and he watched, slightly fascinated, as Sebastian first pulled down his pants, then his underwear. Ciel suddenly felt self-conscious about being completely naked in front of Sebastian. He has been plenty of times, but this was the first time that something like… this was happening. Sebastian, with that ever-present smirk, started to kiss his way down Ciel's chest, past his navel, to his crotch. Then, with another flash of pink to his eyes, Sebastian stuck his tongue out and licked the top of Ciel's member. Ciel immediately groaned, and Sebastian started to suck the tip, then travel down until he eventually had the whole thing in his mouth. He started to move his mouth up and down Ciel's shaft, and Ciel bucked his hips, trying to press further into Sebastian's mouth. Sebastian licked the underside, then all around until Ciel was back in his mouth. Ciel started to feel a knot form in his stomach, and he groaned louder. Sebastian, sensing that that was the case, stopped licking and sucking and sat up. Ciel whimpered slightly, having had the pleasure taken away.

Sebastian leaned over Ciel and whispered in his ear, "Don't worry, young master. There will be more pleasure soon." Ciel widened his eyes at the sound of that sultry voice. Sebastian stood up from the bed, and took off both his pants and his underwear to show his erect member. He got back on the bed, and started to feel around Ciel's thighs, to the back of them, and eventually to his ass. His fingers found what they were looking for, and Sebastian gently put one finger up Ciel's butt. Ciel gasped in pain and clawed at the sheets, whimpering and gasping. "Relax, young master. It will make it less painful." Ciel relaxed slightly, and when he got used to the first finger, Sebastian pushed a second finger in. Ciel gasped a little and then groaned when Sebastian started to scissor his fingers inside of him. Sebastian then put a third finger inside, and started to push his fingers in and out, slowly at first, then building speed. Ciel cried out, and when Sebastian curled his fingers and thrusted them in again, he gasped loudly, seeing white. Sebastian smirked, having known he had found that special spot, and thrusted his fingers again. Ciel groaned and grasped Sebastian's hair, pulling slightly. The knot in his stomach started to tighten. Suddenly, Sebastian pulled his fingers out. "Are you ready, young master?" Ciel, gasping, managed to nod. "This will hurt a bit until you get used to it," Sebastian warned, then pushed his shaft all the way into Ciel until it was buried to the hilt. Ciel cried out, tears forming in his eyes, and Sebastian leaned over and kissed him briefly, before pulling out and pushing himself back in. Ciel whimpered, but after a few painfully slow thrusts, Ciel said, "F-faster, Sebastian." Sebastian, smirking again, started to pull in and out faster. Ciel cried out and managed to gasp out, "H-harder! Ah! Faster p-please!" Sebastian started pounding into Ciel at a speed only a demon could manage, and Ciel gasped in pleasure as Sebastian hit his prostate. Sebastian continued pounding mercilessly, and soon Ciel started panting, "I-I'm go-gonna co-" and suddenly his words were cut off when the knot in his stomach released. He nearly screamed as cum hit Sebastian in the chest. Sebastian pounded a few more times until he came into his beloved young master. Sebastian pulled out of Ciel, and Ciel collapsed onto the bed, panting and gasping. Sebastian lay down next to him, and whispered in his ear, "You are mine, young master. No one else can have you." Ciel nodded sleepily, and crashed into oblivion. Sebastian got dressed, clothed Ciel somehow without waking him up, and sat with his young master until the barest streaks of dawn appeared on the sky. Then, he went off to start the duties a butler had to accomplish.
