Sebastian x Reader
---Sebastian's pov---
My hands were still on her stomach…I didn't think…I didn't know that…
"B-but demons can't have children!!" I shouted, I'd never heard of such a thing, it had never happened before. "Not with humans at least…normal hum-oh." I laughed a little at my own stupidity, of course I could have a child with her…she wasn't a normal human. I raised my left hand to cup her face. "Don't worry milady. Now we should really go shopping, the both of us need costumes for tomorrow's annual fancy dress ball." I smiled into her confused eyes, she clearly didn't understand.
"b-but I can't have a baby…….I-I-I d-don't…….I-I-I can't d-do it-t…..S-Sebastian I-I'm only eighteen! I c-can't be a m-mother I w-wouldn't know where to s-start" She stammered. I held her close to me in my arms. I could only smile, the thought of becoming a father it was all a little too much for me. What could the child possibly look like? A baby…with red eyes…and cat ears…well at least it would be cute.
"Don't worry, you're strong," she looked up at me. "You can do anything, you are perfect." I placed a finger under her chin and kissed her cheek before moving to her ear to whisper, "You are mine now, I will always be beside you." When I looked at her again her eyes were shining and filled with tears, she blinked and a single tear rolled down her cheek. I wiped it away, I didn't like seeing her cry, I silently vowed to never let her cry again. I kissed her again and made her sit up it the carriage. "we are ready to go" I called to the driver. 
As the carriage began to move she borrowed into my side and wrapped her arms around me. "A-and I will always be there-" She whispered to me. "-beside you." I stroked the ears that she made pop out of her hair I was smiling.
"hey," I murmured to her. "you are going to be a mummy…and I'm going to be a daddy." I held onto one ear for a moment. "I will always protect you both, we are going to be a family." She shuffled a little and then went quiet. Her ears occasionally twitched but that was the only movement I could sense from her. She was asleep.
---Your pov---
I was amazed at myself…at him. I had really known him for only a week at yet we were engaged and I was going to have his child. We were walking hand in hand down a street that I remembered fondly, It was there that I had once been given a slice of bread from a passer-by. I noticed how many girls my age would stop and stare at Sebastian and me. "How wonderful" they would whisper. "What a beautiful couple." Some would say. "He is so handsome." Others would swoon. Then I heard a low pitched growl…for a moment I was terrified thinking that infernal dog, Pluto had followed us, but when I turned there was nothing there. I hadn't noticed the way Sebastian had stiffened slightly or the way his eyes had begun to glow I was having too much fun listening to the swooning girls around us.
"Beautiful."
"wonderful"
We turned down a narrow alleyway and kept walking. Sebastian kept cool and pulled me slightly closer to him and I saw a silver thing whirr passed my head whilst making a buzzing noise.
"You bitc-" I turned startled to see Grell's head smashed into the floor by a smartly dressed male. He had dark hair and wore square glasses (which he continually adjusted with a pair of what looked like hedge clippers) but what stood out most about him was his eyes. They were the exact same style as Grell's. Those peculiar Green and yellow banded eyes that looked so strange on the eccentric Grell looked even stranger on the neatly dressed man stood in front of me. 
"tsk." He tutted. "Grell Sutcliff! I thought I told you not to reap anyone who isn't on the list." He adjusted his glasses with his hedge clippers once again and looked at me. He sighed and bowed to me deeply. "I apologise miss ______, for my…colleague's behaviour" I bowed to him too and when he looked up his eyes widened at my gesture. 
"Are you a reaper too, sir?" I asked him politely with a smile on my face (I thought it would be best not to anger him). He blushed a deep crimson and then looked away with a stern looked plastered on his red face. I giggled quietly.
"My name is William, Miss ______, William T Spears."  I smiled and bowed again before kneeling and lifting his foot which was gradually leaving an imprint on Grell's head. Although he had tried to kill me at least twice now I didn't like how he was treated. William looked down at me with a puzzled look on his face, but allowed me to move his foot.  Grell looked at me with a confused look too.
"Are you okay?" I asked him helping him up.
"L-l-let go of me you tram-!" Grell said whilst shrugging off my hands and looked away from me. Will kept staring at me but hit Grell lightly over the back of his head with his clippers. Grell seemed to have lost the will to kill me, which was good.  
Sebastian laid a gentle hand on my shoulder which instantly drew Grell's attention. "William, Grell I'd like you to meet," he paused and I could hear the smirk in his voice. "My fiancée, Miss ______." Grell bared his shark like teeth and will's jaw dropped to the floor, he looked a little disappointed, Grell looked like he wanted to throttle something. Will grabbed the scruff of Grell's neck and forced him to bow.
"Congratulations" said Will. "We best head back to headquarters." He shook Sebastian's hand and kissed the back of my hand before dragging a suddenly sobbing Grell away. Sebastian patted the top of my head and laughed.
"That showed them didn't it, my kitten?" I blushed, I liked that nickname. "now we really should look for some costumes.
"I know what I want to be." I smiled at him looking up. "A cat, though I have the accessories already, I'm not sure what dress to look for." He grinned and proceeded to pull me towards a very strange looking shop called 'New-era'. Most of the clothes were short dresses and skirts, but they also had a large lingerie section. Sebastian drooled a little and tried to drag me toward the lingerie, I just glared at him. "Eyes on the prize, my little demon."
"I'm afraid my eyes are on the wrong prize, my little kitten. Go and choose a dress and I will just wait by the changing rooms." I looked at him icily, but when he smiled I melted and scurried off to find a dress that he would like. 
I walked through rows and rows of dresses both mini and maxi. Some were garish, some were girly and some were downright terrifying (dresses that only Lizzy could be proud of). After about five minutes of searching my eyes fell on a dress that I actually liked. It was black  and stopped about four inches above the knee. It hugged tightly around the top and had no straps. A belt decorated with a cluster of fake diamonds was secured just under the bust area of the dress. Below the belt the skirt poofed out a little and there was a black net laid over the top of the skirt. I loved it and I was sure we could cut a little hole in the back for my tail to poke through. I also spied a small make-up set and a pair of little black strappy shoes in the shop, I might as well spend a little more of the money I have earned. I walked up to where Sebastian was sat staring at some lingerie he had picked out. I threw the make-up set at him. "Hold this, I'm getting changed…and put that away." He looked at me with puppy dog eyes holding out the underwear. I couldn't help but giggle. "No!" he leaned closer to me "no…" my voice wavered a bit when our noses touched. He kissed me gently,
"Please…" he murmured childishly against my lips. I pulled away from him and sighed, rubbing my head. 
"Okay fine," I held out the dress I had picked, "I'm going to get changed now, wait here." He nodded happily, he looked strange today, it was as though since he had said he would be a daddy soon this morning. I thought he must be happy with the thought. I walked into the dressing room and came back out with the new dress on. It looked even better when I wore it than it did on the hanger. Sebastian's head snapped up when I walked out and his mouth fell open.
"You need to pick another one." I was shocked
"You don't like it?" I questioned him, I was a little upset, I was sure he would have liked it.
"No." he stood up quickly and put his hands on my shoulders. "I love it, you look beautiful, you always do…but, I don't want anyone else to see you in this dress." He looked at me and hugged me running his hands along the dress. His eyes looked hungry and started to glow he bit down on his bottom lip. I put my hands on his chest and pushed him away slightly.
"Look if you let me wear it tomorrow then I promise I will wear that-" I said pointing to the lingerie he had chosen. "-tomorrow night to bed…deal?" His eyes glowed bright pink. 
"Deal!" he snapped, suddenly pushing me back into the dressing room. "Now get changed, we need to pick out my costume." I smiled as a picture of Sebastian wearing a pair of cat ears popped into my head.
"How about we wear matching costumes?" I called to him.
"You mean I dress as a cat too?" I giggled at the surprise I his voice.
"Yeah," I stepped out dressed back in my red dress and laughed to see Sebastian wearing a pair of cat ears.
"What? Is there something on my head?" he feigned puzzlement, raising a hand to his head, and scratching the ears as if considering something important.
"Ooh they suit you." I said standing on my tip toes so I could stroke the ears as he had done with mine many times before.
*The next day-just before the ball started*
I slept alone last night. Sebastian said he had many preparations to make for tonight's dance, when I went down to the ball room he was there hanging some of the Phantomhive family flags from the ceiling. The place looked incredible there was a buffet table full of a wonderful spread of food and an intricate ice sculpture of Ciel was sat on the table.
I crept up behind him when he had stood back to inspect his work and placed the cat ears on his head. I giggled and bowed to him. "Sebastian, Ceil asked me to tell you the guests are starting to arrive. He wants the two of us to start greeting them."
The two of us stood on either side of the front door and welcomed guests s they arrived. There were dukes, duchesses, nobles, earls and international royalty on the guest list. We bowed to them all and directed them to the ball room. Some of the guests stood out more than others. One was an indian prince and his servant, The prince was handsome and about my age, he was dressed as Sherlock Holmes. He was called Prince Soma and upon seeing me he declared to his servant Agni (who was dressed as Watson) that he had found his Queen. He and Agni hugged one another and cried. Sebastian coughed.
"I'm sorry Prince this is Miss ______ and she is my fiancée." Prince soma went quiet but brightened up again when I promised him and Agni a dance later on.
There was also the Viscount of Druitt, Lord Aleister Chamber, he said I looked like a robin and kissed my hand. I hated him as soon as I saw him (why did he have a blue lobster on his head) and pulled my hand from his grasp.
"Ah sir, I have literally eaten robins for breakfast," I said to him menacingly. Sebastian snickered.
"I do like women with a little spice." Laughed the Viscount. "We will dance later." It wasn't a request it was a demand. I just nodded happy at the thought of being able to talk down to him more later. When he walked away Sebastian pulled me into his arms,
"I'm so glad I'm marrying you." I smiled up at him, then we heard the scream from inside the ballroom.
