Welcome back to His Butler's Maiden, my amazing peeps! Thanks for the nice reviews! Here's chapter 4.

Cassandra woke up in the middle of the night. She knew that everyone was still asleep. She got up, shivering in the small December draft. She put a robe on and headed for the kitchen for some tea.

She eventually passed Ciel's room and heard a small noise. She stopped, putting her ear against the door. She heard a cry and she entered the room.

"Young Master Ciel?" she called softly. She saw Ciel thrashing in his bed and whimpering. She walked up to him. "Ciel, wake up." She leaned in only to be smacked in the cheek by his unknowing hand. She held her cheek and sat next to him, putting her hand on his forehead. "Ciel, please wake up. It's alright." Ciel eventually awoke at her touch and stared at her in fear. She lifted him and cradled the boy in her arms and pet his head soothingly.

This was familiar. Cassandra remembered this from three years ago.

(Flashback)

Cassandra lay on her side, trembling on the cold stone floor of the cage. She was covering her ears, trying to block out the loud screams of the ten-year-old boy that this damned cult was torturing. The screaming soon stopped and she looked up. One of the masked men was standing at her cell door, holding the small child in his hand. He unlocked the door and threw the child inside. He landed next to Cassandra as she stood. The man walked away.

Cassandra looked down at the trembling boy and she knelt next to him, lightly touching his shoulder. He flinched and looked up at her, fear trekked all over those deep oceanic eyes. Cassandra got up, walked over to her water basin, and brought it over to the child. Using a scrap of her shirt, she cleaned the blood off of his wounds and soaked his head for him. He eventually welcomed her touches and closed his eyes. Cassandra lifted him when she was done and cradled the boy.

"What is your name, little one?" she asked. The boy looked at her and nuzzled into her arms.

"C-Ciel… Phantomhive," he said weakly. Cassandra pet his head and rocked him back and forth.

"You'll be free soon, Ciel," she said. "I'm sure of it." Ciel looked up at her, tears welling in his eyes and Cassandra embraced him gently. "It'll be okay."

(End of Flashback)

"C-Cassandra!" Ciel cried as he clung to the girl, tears launching continuously out of his eyes. Cassandra held him close and rocked back and forth.

"Shhh, Ciel," she said softly. "It's alright now. You're not there anymore."

The door suddenly creaked open and Sebastian walked in, worry on his face. Cassandra looked up at him and put a finger to her lips. Sebastian walked in and sat on the bed next to her.

"I heard the young master cry," he said silently. "Is he alright?" Cassandra continued to soothe the boy, whose pride was too great for him to look at his butler. Sebastian was the one person that Ciel never wanted to cry in front of. He soon felt drowsy again and was starting to drift off to sleep. Sebastian took the boy from Cassandra's arms and lay him back on the bed, tucking him in. "Have better dreams this time, my young master," Sebastian said as Ciel finally fell back to sleep.

Cassandra stood before Sebastian and bowed her head.

"Forgive me for imposing on your job, Sebastian," she said. "I didn't want him to be alone." Sebastian grabbed her hand and led her outside the room.

"Cassandra," he said, putting his hands on her shoulders, "I'm not upset about that. Like you, I don't like seeing the young master in pain. He won't allow himself to cry in front of me for reasons I do not know, but he has no problem with you." Cassandra stared at him, knowing he was about to order something of her, then put her hand over her heart and bowed.

"What is it you wish me to do, Sebastian?" she asked softly. Sebastian put a finger on her chin and lifted her to face him.

"Never leave my side, nor his, Cassandra," he said in a serious tone. "You will move at my beck and call, but you will attend to the master when he needs emotional help. Do you understand?" Cassandra looked at him in surprise and stared into his crimson eyes. After a few moments, however, she smiled and nodded.

"Yes, Sebastian," she said. She reached up and touched her necklace and looked at Sebastian again. "Should Ciel ever know of my true form?"

"Only if the occasion should call for it." Cassandra smiled and nodded again. She got down on one knee, staring up at her demon master.

"Then, by Lucifer and my title of a fairy," she said, "I shall never leave your side." Sebastian smiled back and helped her up.

"What is your title of a fairy, may I ask?" Cassandra frowned and looked down.

"I am the Fairy of Impurity," she said quietly. Sebastian's eyebrows rose at this and he smirked, lifting her chin.

"How intriguing," he said in what Cassandra recognized as a seductive tone. Sebastian snaked his arm around Cassandra's waist and pulled her a bit closer. She crooked an eyebrow and stared at him with a smirk.

"Exactly what makes you think an honorable fairy like me would submit to a fiend of Hell like yourself, Sebastian?" she asked with a hand on the demon's face. Sebastian chuckled and lifted her up, carrying her to his bedroom. She eyed him with seductive suspicion as he opened the door, tossing her onto his bed.

"I believe I have ways to persuade you, dear Cassandra," he said. "And, as you promised, you will not leave my side." Cassandra smiled at this and pulled his face down to her level.

"Then I must stick to my word," she said as she pulled Sebastian down and kissed him. He immediately forced his tongue into her mouth and pulled at the laces on her dress. She responded with a light moan and kissed the demon harder. He finally got the laces undone and he tore off her skirt with force. He looked down at her undergarments and his hands crept to the laces of her tight corset. She suddenly put her hand over his, stopping his actions. He looked at her in surprise. "Sebastian," she said, "what will become of this? Am I to be your lover or just your whore?" Sebastian looked at her in shock and he sat up a little. She continued to stare at him and he blushed a bit.

"I don't wish to take advantage of you, Cassandra," he said softly. "I won't force you if you don't want to." Cassandra sat up suddenly and attached her lips to his again, surprising him. She pulled away and stared at him.

"I want to, Sebastian," she said. "I just want to know if you plan to love me as I love you." Sebastian crooked his eyebrow and touched her face lightly.

"Why would you love me, Cassandra? A 'fiend of Hell'?" Cassandra smiled and kissed him.

"You saved Ciel from a torture that no one should experience. I never did think I would ever meet a kind demon." She stared at him with a knowing expression and laid back down. "Now are we going to make love or just continue talking?" Sebastian smirked and lay on top of her and kissed her neck. He went back to her laces and undid them in a minute. He took the corset off of her and sat up to look. His mouth opened a little in shock as he stared at her naked torso. Her breasts were full and firm. Her stomach consisted of a tattoo of the sun around her stomach. He reached over to her necklace and picked it up by the medallion. She stopped his hand again and stared at him. "My form is a bit… inappropriate," she said, blushing. Sebastian smiled and unclasped the jewelry from her neck and watched her transform. Her hair volumized, her skin darkened with a red tint over her tan skin, and a tattoo appeared upon her face, wrapping around her eye and down to her belly-button. Her breasts even grew a size. Her wings appeared behind her and spread. Sebastian stared and smiled at the sight. He bent down and put one of her breasts in his mouth, licking and teasing her nipple. She moaned and ran her fingers through his raven hair.

Sebastian puts his hands on her underwear and slid them off of her legs. He reached up and began unbuttoning his tailcoat. Cassandra sat up and helped him. They eventually got his uniform off and she stared at a beautifully toned chest and reached up to touch it. It wasn't too muscular, but it wasn't skinny either. It was… perfect. Sebastian let her hands travel over his body until they reached his trousers. He put her hand over the button and smirked down at her.

"If you would?" he asked her. She smirked and undid his pants for him and slid them off of him, including his underwear. She gawked at his gorgeous member and touched it lightly running her nails over it. He grunted softly at the touch and put his hand on her abdomen ran it down to her area. "You really are a beautiful creature, Cassandra." She looked at him with now maroon and brown eyes and smirked.

"As are you, Sebastian," she said.

You guys may or may not hate me for that, but I don't like doing guy on girl smut… yaoi is so much more fun and easier to describe. Sorry and hope you liked it.
