Sebastian x Reader (lemon)

Party with how many Demons?

(You pov)

"Are you two known to make a mess, " an angry yet sobbing voice came from one of the broken windows, Sebastian covered using with a blanket. I looked at the window to see Grell. How long has he been standing there?  I blush a deep red as Sebastian pulls me close under the blanket. My body still tingling from earlier. I felt alive like I could do anything. Sebastians arms around me, us skin to skin, made me happy. It felt right, but when Grell came in through the window looking around at the mess my happiness faded a little. "What the hell are you doing here, " I growl finding my voice as sharp as a blade. "I came here for the ball," Grell glares at, well I don't know it was either me or Sebastian. "How long were you there," I ask glaring at him. "Long enough to know you love oral, " Grell shoots at me. I was on my feet in a flash, forgetting I had no clothes on. "you little shit, " I glare, but then feel Grells eyes on me.  I can feel Grells hungry eyes take in my flesh. "Mmmm, "Grell smirks pulling me close, "Sebastian nice pick." "Let her go, " Sebastian growled. "I t-thought you were a girl," I said blushing. "My dear, " Grell smiles, " I can be anything you like." He presses me into him. I shove him away and slip on anything that was near me. I was wearing Sebastians button up shirt that barley covered me to my ass.  Sebastian was now in his pants, he had dressed under the blanket so Grell wouldn't see. "You aren't supposed to be here Grell, " Sebastian said pulling me close. "And you two should get ready for the party, " Grell smirks, " not fucking." "She is mine, " Sebastian growls clearly getting jealous as Grell continued to look at me. "Not  till marriage, " Grell smiles. Sebastian didn't like this," she will be mine,  but she is already my mate." "Till then, " Grell said pulling me out of Sebastians arms and kissed me deeply. I was shocked and shoved him away wiping my lips on the shirt sleeve. "Mmmmmmm, " Grell licks his lips.  Sebastian growls and pulls me close, so close we were squished together. "Get out Grell, " I said in a flat tone, " so we can get ready." Grell smirked and leaves. I flop on the bed sighing. Sebastian asked softly, " you alright love? " "Just nervous, " I smile up at him.  We get dressed and clean up the mess.  We headed to the ball room music was playing, people where dancing and laughing. Someone announced us. Many people didn't know who I was and how much power I held, many gasped at the sight of me.  I could hear all kinds of comments, " (y/n) is beautiful !" "Why is she marrying a butler ?" "She could do better. " "He is so handsome, Who is he engaged to? " "Why haven't we seen her around, I would have talked to her. " "How much do you want to bet he beats her? "

I ignored them as I walked with Sebastian who's arm was inlocked with mine. We were dressed in matching colors,  (f/c). My dress had a corset and the bottom was flowing down my body a little puffy, because it was for an engagement. Sebastian had helped me put my hair in a style I loved.  I smile at Sebastian as we began to dance.

(Grell pov)

Why did I care about (y/n)? I thought I was in love with Sebastian, but when I look at her my heart flutters. When she took my souls yes I was trying to get them back, but at the same time I didn't want to hurt her. I wanted her, but she was Sebastians mate.  I was jealous, but I couldn't tell for which one. Maby for they get married I can be a third party, since I couldn't make up my mind. I watched as they dance together as if no one was in the room. I couldn't help but to smile, but it soon fades. Ciel was standing next to me. "So you walked in on them, " he smirks. "How did you know, " I glare at him. "It's not like they were being quiet, nor were you when you interrupted, " Ciel said having a slight blush on his cheeks," why didn't you stop them earlier?" How could I answer that to this boy who thought he was older. Yeah, like I am going to tell him I was jacking off at the sight of Sebastian fucking (y/n). I just walk away.

(Ciel pov) 

Grell just walked away, what could have been his reason? Sebastian and (y/n) no doubt broke some things in the room,  we all could hear the crashing and what not.  Just the thought of it makes me blush. Will Elizabeth and I be like that in the future? Hell all they are waiting for was for me to announce when I wanted the wedding, but was I ready?  Was Elizabeth ready for that step? Since my soul was to be devoured by Sebastian I needed to have a child. I might have to have the wedding with Elizabeth soon. "Ciel, " a soft voice asked bringing me out of my thoughts. I look to the person finding it was (y/n). "Are you alright, " she asked softly. "Yes,  just in thought, " I smile a little at her. She always seems to make me happy like Elizabeth, but I hide it.  I didn't like to admit I have weaknesses. She hands me a drink, but her body jolts. "(y/n)," I said worried ," are you alright? " She smiles and nods, " yes sorry I am just nervous." When people are nervous they don't jolt out of nowhere. I go and find Sebastian to tell him.

(You pov)

The hell was that ? My body feels weird so sudden, I felt like I needed to vomit. Can a demon vomit?  I rush to the bathroom only to bump into a kid with blond hair. "Why (y/n) why would you be leaving your own engagement party so soon, " he asked giving a perverted smile. He grabs my hand and kisses it. "My name is Alois Trancy," he smiles at me.  "Excuse me, " I said as I take my hand away, " but I need to go do something quickly I will be right back." "Promise, " he asked. I smile, " of course." He smiles and does a little dance around me. I then go to the bathroom, and I walked straight to the mirror. I looked the same, but something felt off. I watch my reflection my eyes flash to a pink like Sebastians.  I what gotten used to it. I run my fingers through my hair breathing slowly. What was wrong with me why do I feel like I need to go to Sebastian? I wanted him to hold me tightly in his arms, to tell me everything was alright. I take a while to pull myself together, I leave the bathroom.  I find Alois Trancy quickly becase of a familiar looking butler. He looked like Sebastian, but he wasn't. Where have I seen him before? Alois ordered that his butler to dance with me. I danced with him ,then with Trancy. I could feel Sebastians eyes on us. Who where these people really, I can sense something. I could sense 5 demons. Looking around I found three purple haired guys and Trancys maid. I looked at Trancys butler to see his eyes flash but then go back to normal. Where they the demons? I felt danger, and I rushed to Sebastian. Ciel was near him dancing with Elizabeth. "Wait, " my eyes widened, " that guy was from my dream. " "Really, " Sebastian asked pulling me close. I nod as I hug Sebastian, slowly ever so slowly I can sense another demon. It was a faint aura but I could sense it. Where were they?
