~Y/n pov~

I buttoned my shirt up as I fixed my gloves on, being the second butler to Ciel Phantomhive, since Tanaka is still having problems. I'm the next solution to the problem.

But one thing is always bothering me.

Sebastian Michaelis.

I know that butler hides many secrets, the other servants seem oblivious to it but not me. Sometimes I catch the man watching me after I finish cleaning the dishes or dusting the shelves.

Sometimes I'd catch him and the Earl sharing some sort of secrets, not about their work of the underworld, but more of the contract they have together. When I'd take my shift of watching Earl Phantomhive, he'd need help getting dressed.

Which is when I caught sight of his brand on his side and his eye. He didn't seem to see that I noticed it. I'd look into that strange marking in the library or with the Undertaker.

And I was correct about it being a seal deal between a mortal soul and a demon. Of course Ciel couldn't be a demon.

But a servant who wore black, perfect at everything, inhumanly handsome and a perfect little liar would make sense.

Sebastian took note that I knew of his true nature and what he was here for. Which led to him following me.

~~~

"The chores I have listed for you-"

"Are all finished." I replied.

"All-"

"All of them."

". . . The dishes?"

"Cleaned and dried and put away."

"The table-"

"Cleaned, prepared, and waiting for the Earl's dinner."

"Garden-"

"I already helped Finny with the weeding."

"Food-"

"Done."

"Cleaning-''

"Already supported Mey-Rin." I added.

I turned around to see Sebastian staring dead down at me.

". . . What is wrong, Sebastian?" I asked.

"Nothing. Your just very good at your job."

"Thank you, is that all? Your standing quite close."

"Am I? I didn't seem to notice." He said with a huskier tone.

I tried to back up but felt the table behind me. I forgot we were in the library.

"I know what you are. . ."

"I know you do. I've been watching you when you left, my lord wanted to know what you were up to." He placed his hands on the table, locking me between him and the platform behind me.

"T-This is no appropriate way to speak to a servant."

"Is it?~ Y/n, you know my secret, let me fulfill your secret desire now~" he whispered to me as his gloved hand held my front button on my coat.

"No, you demons don't have feelings. You just want to fulfill your lustful needs!" I growled as I pushed past him and away.

~~~

At night, I was in my own private servant quarters. As I slipped off my coat, I was about to undo my shirt until two gloved hands held my shoulders. I was about to scream until the hands covered my mouth.

"Shh~" he hushed.

"Mmm!- You bastard! Let me go!" I hissed, but when I struggled, I felt a kiss on my neck.

"Sebast-"

"Hush, Y/n. You've always been irritating to me, but now I know why~ it's because I'm infatuated by your beauty~" he said as he made me look at him.

"This is just your lust talking." I said through gritted teeth.

"It is not my lust~ it's something more complicated than that~"

Sebastian Michaelis, a demon who was seducing me. I couldn't let him win. He's a demon, all he wants is to have some sort of release, but from what? Stress? Overworking? I don't know.

But what I did know, is that his face was very close to mine. His fingertips lifted my face to his, he then softly kissed me. Unknowingly, I kissed back.

My arms automatically held the collar of his shirt. His tongue enter my mouth, he was somehow amazing with his mouth. He walked me back to my bed and laid me down as he kissed me more passionately.

He undid my white shirt as I took care of his. I felt his kissed trail from my shoulder to my ear, I wanted to stop him, this wasn't love. Demons can't feel love, bit this was too damn good.

"More~" I muttered as he snuck his hands into my pants.

"As you please." He answered as he began to press on my clit.

He kissed me again as I arched my back even more, trying to get more friction from his hand. He kissed my neck next and slid off my pants and underwear, I undid his belt and pulled his shirt off.

I kissed his collarbone as he unclipped my corset. Sebastian flipped me over on my stomach before kissing my back, he arched my hips as he licked my shoulder. He sculpted body pressed against my back as I felt his erection.

"Sebastian~"

"Prepare yourself, Y/n~" he then pressed his tip into me.

I clenched the sheets as he pushed more, I stayed quiet as he thrusted into me. I squealed as he held my arms behind my back.

"Sebastian~ You demon~ what did you do to me~" I whined, Sebastian chuckled as he nibbled my ear.

"You have been inside of my head everyday, Y/n~ you know my secret and I now I know yours~" he grunted as he held my hips.

His flesh hit mine as he began to get faster and rougher. The bed was creaking, my body was beginning to shake with pleasure and building euphoria. My body was struggling to hold up for him, Sebastian was drilling the shape of his cock inside of me.

He squeezed my ass and held my leg up as he fucked me. The clapping sounds were so new to hear, soon he had me on my back and kissed my breasts. I held his soft hair and brought him into a kiss, kissing a demon, something I never thought were possible.

"Ah~ S-Sebastian~ love me~" I sighed against his lips.

He cupped my breasts as he grinded deeper into me. I held him with my legs as he bit my neck, I saw his eyes shift into a glowing pink color. He took my gloves off and kissed my hands, I used my right hand to trace his body as he made love to me.

He held up my back and made me sit on his lap. I lifted myself and let myself fall back down on his dick, riding him as he buried his face into my breasts. I hugged him as I held his hair, feeling his hands on my hips as he kissed and guided me.

"Your so perfect~" he purred to me.

His teeth were a bit sharper as he pierced my skin and began to hug me tighter as he shoved me down on his cock, I couldn't help myself as I squeaked before moaning.

My walls were clenching on his dick, I was drooling as he kept going. Laying me back into a doggy style pose, he was aiming for my G-spot already.

"Sensitive, dear?~" he chuckled as his hands held me.

He striked my area so many times, my moans and screams were muffled by my pillow as he was close to breaking my bed.

He bit my shoulder as we both broke our climax. Instantly, I felt his thick cum fill my stomach already. I shivered as he softly stroked my sides, he laid on me as we both took our breaths.

I felt his lips kiss me as he carefully pulled out of me. Leaving me empty and sensitive, I rolled on my side as he laid beside me. I looked into his hazel colored eyes, he held my hand in his and kissed it.

". . . Sebastian. . . What did we just do?" I asked.

"Made love, of course." He grinned.

". . . Love or lust?" I added.

"Why not both?"

"Sebastian, tell me honestly. I know you're a demon, you are incapable of feeling love or remorse. . . Sense of loss. You can feel angry or frustration. . . You were probably angry or frustrated about me knowing about Ciel's contract with you. You wanted to do something about it an-" he cut me off with a kiss.

"I don't know much about human emotions. . . But what I feel around you or about you is not frustration or anger, not even loss. . . It's something else that makes me feel strange."

". . . Sebastian. . . Are you in love with me?"

Sebastian held my hand and looked at me.

"I believe I am." He smiled.
