Sebastian x Reader (lemon)

Who's the kitten now?

(You pov)

Sebastian looked like he was going to open up his mouth when suddenly he shrank!  I looked at Sebastian shocked. I gasped when I see a pair of ears go up and a tale come from the back.  I pick him up, he was so tiny! (c/n) was giggling when she saw the ears and tail. Sebastian looks at me. I am sure I made a squeak seeing how small and adorable he was. "Sebastian, " Ciel was smiling, " seems to me you got what you wanted, a kitty cat." One of Sebastians ears went down as he turned his head side ways. I craved one of the spoon and showed him. He saw his reflection and purrs. He started to touch his ears and his tail. The inter time blushing. He looks up at me and I give him a little smile. "What caused this, " Ciel asked. "I don't know my lord, " Sebastian said and his voice has changed to a cute little one. I blush and hold him close. (c/n) rushed over to use to get a better look. Sebastian strokes my fingers softly. I smirk getting an idea. I set Sebastian on the table but then (c/n) picks him up. She smiles and kisses his cheek then cradles him like a baby in her arms. "Your so cute, " she smiles. Ciel found this amusing. "Set him on the table baby girl, " I told her and she sets Sebastian back on the table. "Let's eat, " I smiled. We began to eat, Sebastian was trying to eat a strawberry shortcake. I helped cut it for him, but he still managed to get wiped cream everywhere. I was smiling as I watch him. He seems to become sloppy not caring after a while, which is not like him. "You alright, " I asked him. He began to lick his "paws" trying to clean himself. "Bath time for you," I smile then looked at the others, " will you to be ok taking yourself's to bed?" "Yes, " Ciel smiles," looks like Sebastian needs help to night. " Sebastian pouts making me smile more, he was so cute!
I take Sebastian with me to our bathroom. I got the water ready after setting Sebastian on the counter then I got undressed. I look over to Sebastian to see him blushing as he watched. "I am getting in with you, " I giggle seeing a little tent in his pants. I rub the tent a little and he purrs. "It's the size of a tic tac, " I giggle making him blush harder ," you are so cute when you blush ." I undress him and he trys to cover his "Tic tac". "Kitten I have seen it before, " I said softly," it won't change anything about us." He uncovers and I pick him up. I sit in the bath and set him on a rubber ducky.
(Yeah just go with it x)
He hugs the duck holding it as I push it around a little. "Did you feel anything before you turned like this babe, " I asked. He looks up at me thinking as his tail sways side to side. "I did feel a shocking feeling, " he said his ears go down. I watch as he floats around me. He drifts off to the deeper part. His hands were wet and he slips off the ducky and into the water. I move quickly picking him out of the water. "You alright, " I asked worried. He was hugging my thumb looking at me. "I am meow, " he said but friend and trys again, " meow,  neow ,now. " I giggle and pet his little head with my finger and he purrs. "We need to find a safe way to clean you, " I said softly as he kisses my thumb. I place him in my palms and put him partly in water just enough for the water to reach his waist. He began to play in the water as I held him there making sure he wouldn't go under again. I would splash him a little with my thumb moving evey now and then. He was giggling which was unusual for him. I couldn't get enough of it. He always seems so sexy when he was regular size but he is so damn fucking cute when he is like this. After a while he was done playing and cleaned himself. He would steal glimpses at me when he thought I wasn't looking, but he would blush seeing I was looking. I set him on the ducky making sure he doesn't slide off. I began to clean myself and the whole time he was watching me, not in a perverted way. "I missed you, " he said softly smiling at me. "Thank you for getting my soul back, " I smile at him picking him up when I was done. I get out of the bath and set him on the counter as I grab a towel. I was about to dry him when he began to lick at himself. "Babe, " I giggle, " I need to dry you. " He stopped and I dried him off. I dried off as well, but I noticed he was chasing his own tale. I smile as I watch, he keeps going in circles to get it. I got dressed into my night clothes. When I grabbed him to get him dressed he was purring. I dressed him in a night shirt that (c/n) had for her dolls.  Sebastians tale came from under and he trys to get it again. "Why are you going after your tale, " I giggle. "I can't believe it's mine, " he squeals. I giggle as I try to peck his cheek but I end up kissing his face. "Your so tiny, " I smile and take him to the room. I place him on a pillow and fold a pillow case. I layed him down and put the folded pillow case over him for a blanket. I lay near him pulling a blanket over my self. "Don't leave me in the morning okay, " I said softly stroking his face with my pinky. He purrs and nods ," I won't leave you." I smile at him as we hear soft rain outside. We fall asleep, he had fallen asleep hugging my pinky.
When I woke it was to the sound of glass shattering. I looked over at Sebastian to see him gone,  then at the window just in time for Grell to jump out. "Grell, " I shout as I go to the window. I see Grell holding tiny Sebastian who was scratching and biting Grell. I take a breath, " hopefully my body can handle this." I jump out of the window running after them. As I expected my body wasn't used to this anymore.
I manage to catch up to them. "Looks like someone is unable to move well, " Grell teases. "Good enough to catch up to you, " I smirk. Sebastian was hissing trying to get away but his tiny arms couldnt move much. "How about a deal, " Grell purrs circling around me. "What deal, " I watch Grell closely. "You can have him back if me you and Sebastian do a threesome," Grell purrs grabbing my ass with his free hand. My eyes widened but my body tensed. "I don't even know what gender you are, " I then flare at Grell. Sebastian didn't like that Grell had grabbed my ass and was trying to bite at Grell. "I can be any gender you want, " Grell trys to say suductively kissing at my neck. I shivered, I couldn't help but shiver I wasn't used to being touched anymore. My burning desire for Sebastian grew, but what could I do?
I quickly grab for Sebastian, but Grell moved faster. "You are in no position to demand things, " Grell smirks, " your soul isn't fully attached to your body yet. The only way you are going to get him back is through a threesome." I sigh in defeat, " fine, but not till Sebastian is back to his normal self." "Deal, " Grell smirks and places a hand on my torso. I feel a burning sensation there and Grell hands me Sebastian. Grell leaves immediately and Sebastian was still hissing after Grell. "You really agreed to that, " Sebastian nearly shouts in his small cute voice. "What am I supposed to do, " I frown at him, " Grell seems to know what my body is going through." "What did Grell do, " Sebastian asked. "I don't know, " I said walking back to the manor. When we got back to the room I got changed. I stopped seeing my skin was red where Grells hand had been. "Stupid Grell, " Sebastian was giggling, " trying to make a deal when you didn't place a mark on Grell back to seal it." I changed then changed Sebastian into his shrunken clothes that I had cleaned earlier. I replaced the broken window and cleaned up the glass. Sebastian was humming to himself while I was cleaning. I looked over to see him doing a little dance. "Awwww, " I smile watching him. He only dances more and blows kisses at me. He would also wink at me while his ears and tale move with him. "My little cutie," I smile.

(c/n) and I had fallen asleep reading a book together on my bed. I woke to the sound of shattering glass and rush to the room that it came from. It was (y/n) and Sebastians. I hear a yawn behind me. I turn to see (c/n) rubbing at her eyes she had ran after me. "My dear, " I said picking her up making her blush, " you didn't have to follow." I walk back to the room carrying her. "I wanted to know what it was, " she blushes her arms wrapped around my neck. When I get to my room and I guess you can call it hers as well since she has been sleeping with me (non-sexual) I placed her on the bed. She smiles and kisses me as I had bent to place her down. Suddenly she used her demon strength and pulled me on the bed with her. I ended up on top of her. We both blush hard, but I kissed her deeply. She messes with my hair making me shiver a little. I lay next to her, " not till we are married my love." She blushes harder, " I d-didn't mean for it that w-way. I wanted you to go back to sleep with me. " "Okay, " I said softly stroking her hair softly. We go back to sleep and when we woke again it was around 10:30.
Thunder and lighting boomed as hard rain could be heard. (C/n) hugs me tightly and I ask, " are you scared my love? " She shakes her head yes, " I had a dream about today an it started like this. " "What was it about, " I asked softly and kiss her forehead softly. "That you lost me, " she said, " that I died and my parents lost me as well. " "I won't let that happen, " I said firmly. (c/n) kisses me softly, sweetly and yet deeply. After a while I get up to leave so she can get dressed. "C-can you help me with the corset, " she asked. I blushed a deep red but I nod. I help her with the corset then leave to get dressed. When I came back she was dressed, she giggles at me. "Here let me help, " she smiles and then tidys me up. We go to the music room. (c/n) goes to the piano and began to play. I sat next to her copying her movements and notes. The door opens and (y/n) entered holding tiny Sebastian.  I smile at them and we played the piano again. (y/n) set Sebastian on the piano and he began to do a "cat" dance. I hate to admit it but it was cute. (c/n) would dance a little and act as if her hands on her head were cat ears. "My kitten, " I smile at her. "Damn straight, " she giggles and we all laughed at it.

* What do you think about Sebastians change (temporary)?

* Think Grell should get a little "action"?

* What would you do if Sebastian had to stay like this for a while and your burning desire builds up to strong?

Yeah a Lemon should be coming soon, but first Sebastian needs to change back.  He will have side affects by the way. Hope you liked this chapter.
