"Esme!" Ciel barked, "Where are the books I asked for?"

Esme looked up from her desk in the library and pointed at the stack on the corner of it. Ciel curled his lip and stomped forward, grabbing them under his arm.

"Next time bring them to me, I don't have time for this!" he told her harshly.

"What's his problem?" she muttered as he slammed the door shut.

It was late afternoon and Esme stared lazily outside. She didn't want the sun to go down because that night happened to be a night of the new moon. There was no use in getting nervous about it since the only person who was likely to see her appearance had already witnessed it. Sebastian had been acting strange lately and Esme tried her hardest to stay away from him. It was an increasingly difficult task because it had been several days since her last meal. She tried to distract herself from the thought but it was stressing her out. She wanted to stay away from Sebastian as long as possible so he wouldn't have a reason to execute obedience orders on her.

Mey-Rin stumbled in the door and meekly asked, "Esme, can I get your help?"

Esme stood, "With what?" she asked cautiously.

Mey-Rin was flushing and fidgeting nervously. Esme arched an eyebrow and patted the maid on the shoulder; causing her to jump.

"What's wrong?"

"I made a mistake…" she said, pushing her large glasses up her nose.

Esme took a deep breath and followed her down the halls. Her eyes darted about, keeping on the lookout for a dark butler. The pair entered the linen closet and Mey-Rin clenched her fists.

"What…" Esme started and her eyes grew large as she saw pink bed sheets.

"I'm so sorry!" Mey-Rin shouted and grabbed Esme, shaking her.

"Aren't those supposed to be white?"

"Yes!"

"What did you wash them with?" Esme asked, pulling herself out of the maid's iron grip.

Mey-Rin ignored her, "When Sebastian sees he's going to be so mad at me! Oh no!"

"Calm down, go help Bardroy or Finny and I'll clean this up," Esme told her.

"Oh thank you!" Mey-Rin grabbed her in a tight embrace.

Esme watched her run out of the room and shook her head. She stared at the pink sheets and had no idea what to do with them since they were for Ciel's bed. She would have put them on her own bed but it wasn't even close to the size of earl's. Esme stooped over and wrapped her arms around the pile of sheets when she froze. The door opened behind her and she tried to look over her shoulder.

"My, my, what a compromising position you're in."

Esme let out a huff and dropped the sheets. She turned and faced the demon butler.

"What do you want?"

"I want to know why my master's sheets are pink, and I'd also like to know why you're in the linen closet when your job is in the library."

Esme flinched, "Don't get mad at Mey-Rin. It was an accident."

"So you were trying to cover for her, how admirable."

A draft of air came through the door and Sebastian's masculine scent hit her like a brick wall. She stood rigid and looked anywhere except him.

"Look at me when I'm speaking to you," Sebastian said shortly, grabbing her chin and yanking her head forward.

"Let me go back to my room."

"No."

Esme tried to pull away from him but he leaned closer so his chin was resting on her shoulder. She bit her lip as the soft spot where his neck and shoulder met was sitting right in front of her underneath his shirt.

"Don't be shy," he said to her in an amused voice.

Esme continued to try and escape his grasp but he was firm. She wrinkled her nose and held her breath. Sebastian slowly placed his lips against her neck and sucked softly. Esme inhaled sharply when he bit her lightly and his scent flooded her system. Her eyes became glazed and she surged forth without hesitation, ripping his shirt back and sinking her teeth into his neck. Sebastian let out a tense sigh and Esme grabbed his hair at the base of his neck and pulled. He didn't like to admit it but he was becoming addicted to their little trysts when she needed his blood. He enjoyed the feeling of her teeth sinking into his skin; it gave him a euphoria he couldn't describe. Her aggressive and carnal behavior also made a deep fire burn in him. It was raging at the moment and all he wanted to do was take her to her room and ravage her until she couldn't remain conscious. Esme yanked away from him with a disgusted expression on her face and a bit of blood drizzling from her lower lip.

"Let me go back to my room," she repeated softly.

Sebastian smirked, "I believe after what I've just given you, you owe me yourself for the evening."

Esme's eyes shot to the floor, she knew that this would happen. She let out a sigh, it couldn't be helped, she'd made a deal with him and wasn't going to break it. Wordlessly he followed behind her as she walked through the dark silent mansion to her room. They entered her room and the butler closed the door behind her with a click.

"You know what tonight is don't you?" Esme mumbled as she walked to the bathroom.

Sebastian walked toward the large window and his red eyes looked at the darkened sky where the sun was about to dip below the horizon.

"Of course."

Esme moved back into the room and stared at his back until he turned around to face her. His eyes were practically glimmering in the dim light and his lips twisted into a contorted smile.

"Now then, take that dress off, you won't be needing it," he told her, not moving.

She complied quickly and stared back at him as the last light of the sun faded on the horizon. She instantly knew that the scars and imperfections on her body were becoming visible. Her eyes shot to the floor in embarrassment.

"Are you ashamed?" Sebastian asked her, "Don't be, demons are supposed to be hideous."

Esme's eyebrows shot up but she said nothing. His comment was a bit of a stab to her already low ego but she wasn't going to let it bother her considering who it was coming from. Sebastian started barking out orders right and left and Esme soon found herself underneath him in compliance. She closed her eyes and thought about morning when this and the mars on her body would be gone.

….

Esme woke up the next day with a content yawn and sat up. She was flabbergasted. Sebastian had been incredibly different the previous night and she was utterly confused. He had always been nasty and caused her pain in the past which was why she had went to talk to him about altering the deal a bit. Last night he had caused her anything but pain, and she was still trying to wrap her head around it. He had granted her amazing and undeniable pleasure and she had had no idea that he was capable of that since he was so mean all of the time.

She threw the covers off of herself and stood up from her bed quickly. As she did so her face contorted into a wince as she realized how sore she felt. Esme walked to the bathroom and eyed her reflection in the mirror with scrutiny. She looked like her regular self but inside she was brimming with contentment after the previous night; it made her want to owe Sebastian a few more favors. She got ready for her day and retreated to the library.

….

Months passed and Sebastian found himself engaging in more and more explicit activities with the librarian. The butler was slowly coming to the realization that he might be addicted to their little meetings. He didn't like this because he knew that Esme only did it for the blood which gave her power over him. The past week the female demon had reverted to her old ways and was ignoring and avoiding him. Sebastian was irritated by her behavior and it frustrated him to no end, she certainly enjoyed the things he did to her, so why did she have to act the way she did? He let out a sigh as he wiped the dinner dishes dry and placed them in a neat stack. He was going to see her tonight and he didn't give a damn if she wanted his blood or not.

"Sebastian!"

The butler's crimson eyes opened widely for a moment as he turned around slowly. Ciel stared up at him with a scowl on his face.

"What the hell are you doing? And what the hell have you been doing the past few weeks? You're acting like an idiot!"

Sebastian gave his master a small bow as he continued his rant, "You've always done most of your work at night! Hardly anything has been done in weeks! You're spending more and more time during the day or during times that I need you doing it!"

"I have new nightly activities to attend to," Sebastian said with a small frown, "I'm still finishing all of my work, just at a different time."

"Well go back to how it was before! And new nightly activities? I know you don't sleep so what on earth are you doing?"

"Fulfilling an end of a contract I made."

"Your contract is with me, I don't recall telling you to do anything different," Ciel said suspiciously.

Sebastian was silent and stared down at his master with a small smile on his lips. Ciel stared defiantly up at him with clenched fists.

"Another thing, I've noticed that you've been wounded on a few occasions… and it's always in the same place."

Sebastian's eyes drifted to the window in the kitchen where he could see the moon shining. His master was quite observant for such a young boy. The bite marks from Esme took a bit more time to heal than a regular wound since they were inflicted by a demon. The butler always cleaned and bandaged them but there were times when the wound would start openly bleeding. The bandage wasn't enough to hold it and he was only made aware of it when the red seeped through and soiled his white shirts. Ciel let out a furious growl as he saw his butler's attention waning.

"Sebastian I order you to tell me what the hell is wrong with you!" Ciel snapped.

"Nothing is wrong with me young master," Sebastian replied simply.

He wasn't lying, he was in perfect physical condition and there was nothing that was hindering him in that way.

"I'm asking about your mind," Ciel added dryly, "The way you're acting is ludicrous."

Sebastian sighed, he couldn't fib, but he could give vague answers.

"I'm having a bit of trouble with a lady, it's nothing to worry about," the butler said in an even tone.

Ciel's eyes popped open, "What?" he squeaked.

Sebastian turned around and began putting the dishes back in the cupboards with a small smile. It was rare to see the earl speechless.

"You… you have a girlfriend?" Ciel asked in a sharp whisper.

"Now, now, don't twist my words," Sebastian scolded him, "I never said that."

"Do you have one?" Ciel asked, rephrasing his question.

"No," the butler stated plainly.

"Well I don't have time for you to be distraught over some woman! So straighten up!" Ciel barked, regaining his composure.

Sebastian smirked and bowed, "Yes, my lord."
