I woke up to an unfamiliar warmth beside me. Groggily, I opened my eyes to find a naked girl snuggled up against me, her head on my chest. My hand, seemingly instinctively, rested on her small breast. I jolted upright, shocked.

"Aoi?" I whispered, disbelieving.

The girl stirred, her cat ears and tail twitching as she stretched. Her bright green eyes, once slits, now sparkled like jewels. She looked around 10 years old, with an innocent, childlike face.

"Aoi, is that you?" I asked again, my voice shaking.

She yawned, revealing more of her body, and smiled. "Ow... master?" Her voice was soft, melodious.

I stared, unsure how to react. My cat, Aoi, had transformed into a human.

"Aoi, what... what happened to you?" I stuttered.

She snuggled closer, her tail wrapping around my waist. She then looked at herself. "I don't know, master. Aoi just felt strange... and then Aoi was like this."

My hand still rested on her breast, and I hastily withdrew it, feeling confused.

"Wait… you know human language?" I said, feeling confused.

"Well… Aoi learned it from you," she exclaimed. "You do talk a lot," she said, still clinging to me.

"Aoi, we need to... uh... get you some clothes."

She pouted, her cat ears folding back. "No, master. Aoi like it like this. It feels... natural."

I sighed, trying to process the situation. My clingy cat was now a clingy human.

"Aoi, listen. I won't able to control myself if you don't wear clothes."

She looked up at me, Looking confused "What do you mean master?"

I blushed, didn't knew how to reply "You don't to know… just wear some clothes or I'll get mad," I warned her.

Aoi snuggled tighter and begged "Don't get mad at me master, Aoi will do as you say… just don't get mad,". She sounded like she'll cry.

I felt a pang of guilt. "Alright… I won't get" I thought for seacond and I asked "Do you wanna get back to being a cat?"

She looked up at me, her eyes sparkling mischievously. "But master, Aoi like being human. I can cuddle you better now."

My heart skipped a beat as she leaned in, her lips brushing against mine.

"Aoi, stop. I'll get mad." I lied.

She giggled, her tail twitching. "Why? Master, you always cuddled Aoi and kissed Aoi when Aoi was a cat. Why is it different now?"

I blushed furiously at her logic.

"Aoi, you were a cat then. Now you're... human."

She snuggled closer, her head on my chest. "Aoi still Aoi, master. Your Aoi."

"Yes! You're still my Aoi," I petted her back, felling love for her.

I took a deep breath, trying to compose myself. "Alright, Aoi. Let's get you some clothes." I got out of bed, Aoi still clinging to me.

"Master, why do Aoi need clothes?" she asked, her voice muffled against my chest.

"Because... it's just how humans do things," I replied, trying to sound logical.

I rummaged through my closet, grabbing a few oversized shirts and sweatpants. Aoi watched with curiosity as I handed them to her.

"Here, put these on."

Aoi took the clothes, examining them. "Master, how do Aoi...?" She struggled with the buttons on the shirt.

"Let me help," I said, kneeling beside her. My 18-year-old self felt awkward helping a 10-year-old-looking girl with buttons, but this was Aoi, my loyal companion.

I guided her hands through the buttons, my fingers brushing against hers. She felt warm and soft.

"There, got it," I said, stepping back.

Aoi looked down at herself, swamped in the oversized clothes. The cat ears and tail seemed out of place, but adorable.

"Master, Aoi look silly?" she asked, pouting.

"No, you look... cute," I replied, smiling.

Aoi beamed, her green eyes sparkling. "Really, master?"

I nodded, feeling a surge of protectiveness. "Really."

She skipped around the room, the oversized pants pooling around her ankles. "Aoi like being human, master! Everything is so... interesting."

I chuckled, watching her. This was going to be an adventure.

"Aoi, come here. Let's figure out what to do next."

She darted back to me, her cat ears perked up. "Yes, master?"

"First, let's get some breakfast," I said, standing up.

Aoi clapped, her tail twitching excitedly. "Yes! Master, Aoi's hungry!"

Before Breakfast, I went toward the bathroom. She followed closely, her bare feet padding softly on the floor, her tail swishing with excitement. I could tell she was taking in every new sensation with fascination.

"Alright, Aoi," I said, grabbing my toothbrush and toothpaste. I started brushing my teeth, feeling her curious eyes watching me closely.

"Master, Aoi want to brush too!" she exclaimed, reaching for the toothbrush.

I held up a hand gently to stop her. "I'll get you your own later today, I promise. For now, let's just wash your face."

She frowned, her ears flattening slightly in disappointment, but she nodded. I wet my hands and gently splashed water on her face.

At first, she flinched, her tail puffing out slightly in fear. "M-Master! It's wet!" she squeaked, almost pulling back.

"It's alright, Aoi," I reassured her, cupping water in my hand again. "It won't hurt you. Just relax."

She took a deep breath, her ears twitching as I gently patted her face with water. She blinked a few times, seeming to get used to the feeling.

"There, all clean!" I said, stepping back with a smile.

Aoi touched her face, seeming pleased. "Aoi feel... fresh! Thank you, Master."

I laughed softly. "Alright, let's get you something to eat."

In the kitchen, I began preparing breakfast, while Aoi watched me with eager anticipation. She clapped her hands as I set a plate of food in front of her with a pair of chopsticks beside it.

Her excitement faded as she looked at the food and the chopsticks, clearly puzzled. "Master… what's this?" she asked, poking the chopsticks tentatively.

I chuckled, picking up the chopsticks and demonstrating. "These are chopsticks. You hold them like this and pick up the food."

She tried to mimic me but fumbled, the chopsticks slipping from her fingers each time. Her tail drooped in frustration, and her face twisted in concentration as she tried again.

"Here, let me help," I said, scooping up some food with the chopsticks and bringing it to her mouth.

She hesitated, her green eyes wide, before leaning forward and taking a bite. Her face lit up as she chewed. "It's good, Master!"

I smiled, continuing to feed her as she eagerly enjoyed each bite. As I watched her, I remembered it was Sunday, so I guess I don't have leave her like this and mentally made a note to buy her some clothes.

After took few bites, I asked, "Aoi, would you like me to buy you some clothes today?"

She nodded, still not sure about clothes. "Master! Can they be soft and comfy?"

"Of course," I assured her, smiling as I thought about what kind of clothes she might like.

I started thinking all kinds of scenarios where she wore different clothes, but stopped before thinking something lewd.

I finished feeding Aoi and decided to eat my own breakfast. As I sat down at the table, Aoi suddenly got up and walked towards me. Without a word, she climbed onto my lap, snuggling into my chest.

"Aoi, what are you doing?" I asked, surprised.

"Aoi like it here, master," she said, her voice barely above a whisper. "It feels... cozy."

I hesitated, but her contented sigh made me relent. "Alright, stay there."

As I ate, Aoi rested her head on my shoulder, her cat ears twitching occasionally. Her tail wrapped around my waist, holding me in a gentle grasp.

After finishing my meal, I pushed the plate away and thought about our outing. "Aoi, we need to get you some clothes that fit. We can't go out with you wearing those oversized things."

"Master, why do Aoi need clothes?" she asked, lifting her head.

"Because people will stare," I replied, smiling. "And it's just more comfortable."

Aoi nodded, seeming to accept that. I stood up, gently lifting her off my lap. "Let's find something suitable."

As I rummaged through my closet, as I still had some childhood clothes stored away, leftover from my younger years. I dug them out and found a simple white dress with cartoon characters on it.

"Aoi, try this on," I said, holding out the dress.

She looked uncertain but took the dress. I helped her remove the oversized clothes and slipped the dress over her head. It fit perfectly, accentuating her small frame.

Aoi looked down, her green eyes sparkling. "Master, Aoi like it! It's soft."

I smiled, relieved. "Good."

After that I grabbed my keys. "Time to go shopping."

Aoi's eyes lit up. "Shopping, master?"

"We need to get you more clothes," I explained.

I led her to my sport bike, a Yamaha R6. Aoi's eyes widened as she took in the sleek design.

"Master, what's that?" she asked.

"My bike," I replied, handing her a helmet. "Put this on."

Aoi struggled with the helmet, but I helped her secure it. I got on the bike, and she climbed on behind me, wrapping her arms tightly around my waist.

"Hold on tight," I said, starting the engine.

As we sped off, Aoi's laughter echoed through the helmet, her cat ears flapping in the wind. I smiled, feeling a sense of freedom with my transformed companion by my side.

We arrived at the clothing store, and I helped Aoi off the bike. Inside, she marveled at the rows of clothes, touching fabrics and admiring colors.

As I walked inside, a realization daunt opon me. I have never been to a girl shop. I told myself to calm down. Trying not to show it to her.

I chuckled, guiding her through the store. "Let's find something you like."

"What do you think, Aoi? Do you like this?" I asked, holding up a cute pink sweater.

Aoi nodded enthusiastically. "Master, I love it!"

As we browsed through the store, Aoi's eyes widened at the array of colors and fabrics. I chuckled, guiding her through the racks. "Let's find something you like."

"Master, what's this?" she asked, holding up a frilly dress.

"That's a dress, Aoi. You'd look lovely in it," I replied, smiling.

Aoi's face lit up, and she nodded enthusiastically. I picked out a few more outfits, considering her love for soft fabrics and bright colors. As we shopped, I couldn't help but think about my dwindling savings. I had enough to cover the essentials, but I wondered if I should ask my parents for help or wait for my next paycheck from my part-time job.

For now, I pushed those thoughts aside, focusing on Aoi's delight. We filled our shopping bags with bras, panties, shorts, tops, leggings, and more. Aoi looked confused but happy, trusting my choices.

Next, we headed to a shoe store. Aoi marveled at the rows of shoes, trying on pair after pair. I laughed at her antics, helping her find the perfect fit.

Back home, I helped Aoi try on her new clothes. Starting with a delicate lace bra and matching panties, I gently guided her through the process. She looked curious but trusting.

As she changed into a cute top and shorts, Aoi twirled in front of the mirror, admiring herself. "How do Aoi look, master?" she asked, her green eyes sparkling.

"Stunning," I replied, smiling. Aoi beamed with pride.

But then, her expression changed. "Master, this bra feels a bit uncomfortable," she said, tugging at the strap.

I knelt beside her, adjusting the fit. "It'll take some getting used to, but it's designed for support."

Aoi nodded, still looking skeptical. I helped her change into another outfit, watching as she explored her new wardrobe.

"Aoi, do you like your new clothes?" I asked, as she twirled in front of the mirror.

"Yes, master!" she exclaimed. "Aoi feel... transformed."

I smiled, my heart swelling with love. "You're still my Aoi, no matter what."

Aoi's eyes sparkled, and she ran to hug me. "Aoi love you, master."

"I love you too, Aoi," I replied, holding her close.

"You should change the way you address me," I asked.

Aoi looked confused and asked "Then, what should Aoi call you?"

"Call me Onii-Chan," I replied.

She nodded enthusiastically. "Onii-Chan…Onii-Chan…Oni-Chan…" and hugged me even tighter.

In that moment, I knew our journey was just beginning – filled with laughter, tears, and unexpected surprises. But with Aoi by my side, I was ready to face whatever came next.
