~Y/n pov~

Sebastian Michaelis was my owner, or protective lovable guard for me. When we first met I was a normal small black cat, sleeping in a cardboard box. We grew a strong bond over one single night when he found me in the old dirty alleyways.

Then overtime of sneaking me some food and water, he took me into his large manor and into his room, he placed me in a closet with other small cats.

He had smuggled me from his young master, named Ciel Phantomhive.

Then I shifted back into my regular body, wearing a small ragged shirt and ripped shorts that went to my knees. When Sebastian caught me; I was sitting on his bed. My tail smoothly wagging on the bed as I looked at him.

I never thought that when he found out about my secret that it would lead to a more. . .

~~~

I was too focused on catching the small fly on the loose in the room to notice the footsteps coming down the hall.

I finally caught the fly and pinned it down on the bed.

"HA!!" I cheered as I sat and finally pawed it to death, the door opened and stepped in Sebastian.

I froze when he saw me on the bed. His eyes were wide as he looked at my strange features. Ears, tail, claws, and small feline fangs.

"I-I- Um, M-Mister Sebastian! Hiya!" I smiled nervously.

He shut the door and hurried over to me.

"What is this?" He asked as he looked down at me, slowly he kneeled and looked at my tail. I saw a blush creep on his face as he caught my gaze.

"Mister Sebastian. . . I'm not a normal cat. . ." I whimpered, my ears pressing against my hair as I played with my hands.

"You're a human?" He asked.

"N-No. . . I'm a Neko. . . A rare creature- NNNGH!!" I hissed as I buried my face in the bed.

"What's wrong?" He asked holding my shoulder.

"N-Not now!~ N-Not now!" I meowed, my toes curling as my tail was standing straight up. I didn't even notice myself unwillingly getting into a low mating position on the bed.

"What are you doing? W-"

"M-Mister Sebastian~ I-I'm in heat!" I mewled. My body was hot and itching where I couldn't scratch or reach.

My hips were swaying as I hissed, I unknowingly reached down to my lower regions. I couldn't tell what Sebastian was doing, but he did get on the bed. I needed something to stop this overbearing pain. I could hear hisses and meows from the closet.

The male cats could smell my heat and they wanted me.

Sebastian sat on the bed against the wall, I turned and faced him, breathing heavy as I moved his legs apart.

"Miss, you sh-"

"C-Call me Y/n~ and forgive me for committing such an act, mister Sebastian~" I laid between his thighs and unzipped his pants.

"Y/n! What do you think your doing?"

"I-I need help! It hurts. . . M-Mister Sebastian~ please!~" I whined.

I gazed into his eyes, pleading with urgency. Sebastian rubbed my ears which made me shiver and gasp as I hit my climax.

"One touch and your already done?~ I'm quite excited about this~" he smirked.

I kissed and licked his briefs as he watched me. He grabbed my tail by the base which made me almost cum again. I shivered when he began to lightly rub my back, I pulled down his briefs and saw his member spring out.

I lightly touched it and blushed, he was huge. . . So big, it made me nervous but need him more. . . I was scared because this was my first time.

I licked up and kissed the tip of it, Sebastian let out a half groan and gasp when I took him in my mouth. It was so good to suck on something, I felt his veins and throbbing cock in my mouth.

He rubbed my hair and pulled my tail as I gagged on his length, I used my saliva and stroked his cock, I took him back in my mouth and purred as he held my head. Playing with my ears, I was small compared to Sebastian, he knew that and picked me up as he slipped off my old shorts.

Making me straddle his lap, he kissed my neck as my tail curled around his length. He lifted my shirt and kissed my breasts, I cummed again and mewled in his shoulder. I was needing my hands into his shirt. He opened his shirt and let me kiss his chest, orgasms flooded me when he simply rubbed my clit. It was hot for me, I needed more.

Sebastian lifted me and coated his cock with my cum that was leaking down my legs. Sebastian whispered sweet words in my ear as he slowly lowered me down onto his dick.

"This- it's my first t-tim- AH!~"

I moaned again when he fully slammed himself inside of me, feeling like he was splitting me in half. He laid me back and held my hip as he started to move inside of me. Blood and cum coated his dick as he kissed my neck and nibbled my ears.

"M-Mister Sebastian!~ Sebast- Agh! Y-Yes!~ Ha~ Ah~" I squealed, "I-It's too much! M-Mister Sebastian! Slow down p-Please- Haa!~ Ah!~"

Sebastian grunted as he looked at me, I was too tight for him, I could tell.

"My my, your very wet~ and pure~ I never thought I'd be doing this~" He whispered, before I moaned he cut me off with his hand.

"As much as I'd love to hear your sweet voice moan out my name~ I wouldn't want to wake the others. Especially my young lord." He began to move again inside of me.

I hugged him closer to my chest as he sped up. I came again on his cock as he thrusted, tears were staining my face as he fucked me with no restraint. It felt so good~ I was getting dizzy from the overstimulation, my uncountable orgasms and flailing tail. I clawed his back by accident but he didn't seem to feel it.

I could have sworn I saw his eyes glow pink as he cummed inside of me.

My legs were bent as I felt him fill me up with his thick seed, drool and mixed tears were stained on the bed, broken pants and squeaks fell from me.

I turned over and pressed myself against him, looking at him as I panted. I felt his cum drip down my thighs as I waited, Sebastian grinned before holding my hips again. Pressing my upper chest down to the bed before thrusting back into me.

I clawed the bedsheets as he went balls deep inside of my wet tight core, he stayed deep inside of me before slowly pulling out and entering me again. He held my tail on purpose before speeding up his thrusts.

"Sebastian~ Sebastian~ Yes~ More~ F-Fuck me harder!~" I begged, he pulled my hair and tail, drool was leaking from my mouth as I bit my lip.

He kept thrusting and digging his nails into my skin, the pain mixed with my orgasms. It was so much, so much pleasure, pain, and lust. A scream erupted from me as Sebastian pushed my head down to the bed.

My walls were so tight, it almost hurt whenever he slammed back inside of me. So much pain, tears, blood, and cum. Sebastian was going to cum again, I felt his cock throbbing again.

He arched my hips back and pressed down on me, my body aching and shaking, his cock reaching deep inside of my body, pressing against my uterus as he came inside of me again.

Sebastian calmly kissed my shoulders and held my face with his hand.

"Do you feel better, Kitten?~" he asked.

I couldn't speak, I could only nod. My heat was satisfied.

"M-Mister Sebastian. . ."

"Yes, what is it?" He asked as he carefully lifted me up and pulled out of my aching pussy before cradling me in his arms like he used to do when I was in my cat form.

"Thank you. . . For everything~" I muttered as I nudged my head into his shoulder. He laid us down and covered me with the blanket.

"Your welcome, Y/n." He whispered as he petted me.

~Extra~

In the morning door opened and revealed Ciel standing there with Bard, Finny, Sebastian and Mey-Rin.

"Who is in here?!" Ciel asked as he entered.

"My lord there is nothing important here." Sebastian sighed.

"Achoo! My allergies-"

"AWW, LOOK AT THESE CUTE CATS!" Finny smiled as he held a small black cat.

"WHAT THE DEVIL ARE CATS DOING HERE, SEBASTIAN!!" Ciel yelled, "NO GET THAT THING AWAY!! I HAVE ALLERGIES!!!"

"What was that?" Finny giggled as he let cat go.

The small cat immediately strolled over to Sebastian, he grinned at the cat and the cat purred against his legs.

"SEBASTIAN!!! GET RID OF THES- Achoo!!"

"I want this one, yes I do!" Mey-Rin giggled as she held a ginger cat.

"NO!!!" Ciel yelled.
