Work Text:
Mio walked into the bedroom and immediately frowned.
The bed had been made up with a fuzzy pink blanket. On top of it sat:
Black cat ears
A matching tail with a silky pink bow
A soft velvet choker with a bell
Paw gloves — huge, plush, pink-padded, cartoonish
“Rika,” she said flatly, “what the hell is this.”
Rika — still in her work skirt, blouse half undone, hair tied up messily from a long day — beamed from the edge of the bed like she was showing off a masterpiece.
"Welcome home, kitter”
Mio didn’t blink.
“This is some weird fetish you know that.”
“It’s not a fetish,” Rika pouted. “It’s an experience.”
“You literally set up a neko costume on our and expect me to go full anime catgirl.”
“Well, yeah. You’re small. Soft. I already pet you all the time. You’re basically my kitten already.”
Mio folded her arms. “I just got home. I have class in the morning.”
“And I’ve been planning for this all week,” Rika said. “You love me, right?”
“I tolerate you.”
Rika gasped and turned away, clutching the gloves to her chest. “I see… it’s okay. I get it. You don’t want to. I guess I can’t force you…”
“Oh, C'mon,” Mio muttered, already knowing where the conversation is going.
“I just thought it’d be a nice experience ,” Rika sniffled. “Thought my precious little sister might want to try something fun with her big sis. But it’s fine. I’ll just go watch some cat compilation video alone while crying.”
“You’re not crying.”
“I feel like crying.”
“You’re literally fake-sniffling right now.”
“But my emotional wounds are real.”
Mio groaned into her hand. Her heart was already cracking — not because Rika deserved sympathy, but because Rika was so pathetic when she played the fake-sad act.
“…Fine,” she muttered. “Give me the damn ears before I regret this.”
Rika spun around like she’d just been resurrected. “Really?! You’ll do it?!”
“I hate you.”
“You love me.”
“I hate that I love you.”
“Same thing~ Now sit. I'll put it on you instead.”
Mio sat on the bed stiffly, expression dark, but face already starting to pink.
Rika gently fitted the cat ears into her hair. “Perfect.”
Clipped the choker around her neck. Jingle.
Slipped on the paws, adjusting the straps.
Then, last, the tail — clipped under the back of Mio’s skirt with a satisfying little swish.
When she was done, Rika stepped back.
And Mio just sat there. Awkward. Rigid.
Gloved hands in her lap. Legs pressed together. Face burning.
“…Now what,” she muttered, eyes not meeting Rika’s.
Rika blinked, then slowly smiled.
“Now,” she said, “you act like my kitten.”
Mio turned to her like she’d been insulted. “You’re not serious.”
“I am. Crawl to me. Say ‘Rika-nee… Mio wants headpats… nya~’”
“I don't even know where to begin on ghat.”
“You don’t have to know. You just do it. That’s what's going to make it cute and adorable.”
Mio groaned, cheeks flushing deeper. “I’m so going to regret this…”
“Im not. Now, Crawl.”
Mio swallowed, then slowly slid off the bed. Her knees hit the rug. Her gloved hands touched down. Her tail swayed behind her.
Her entire body radiated secondhand embarrassment.
She took one shaky crawl forward, then two, then three.
“...R-Rika-nee… M-Mio wants headpats… nya…”
Rika gasped and covered her mouth. “this is as good as i imagined it to be.”
She then reached out and gently pulled Mio the rest of the way into her lap, wrapping her arms around her from behind.
“There,” she whispered, nuzzling against her cheek. “That wasn’t so hard, was it?”
“It was, and I hate this…”
“You don’t. You’re just shy.”
“I really hate this.”
Rika pet her hair between the ears. “Want to keep going?”
Mio froze.
“W-What's… next anyway …”
“Show me your paws,” Rika said, pulling back slightly. “And say ‘Mio wants kisses~ nya’ and press your paw to my cheek.”
Mio swallowed. Then, trembling:
“…M-Mio wants… k-kisses… nya…”
She pawed at Rika’s face, cheeks bright red. The bell on her collar jingled.
Rika leaned in and kissed her — soft, deep, warm.
“Good kitten,” she whispered. “Now… one more.”
Mio shivered. “What is it…”
Rika tilted her head, exposing her neck.
“Lick.”
Mio blinked. “Excuse me?”
“You heard me. Cats lick who they love.”
“Rika, I swear—”
“You’re halfway there already. Go on.”
Mio hesitated… then leaned in and gave a single, slow, shy lick to Rika’s cheek.
She felt Rika’s breath catch.
Then her sister kissed her again — firmer this time, her hands sliding under Mio’s blouse, stroking slowly along her skin.
“You’re trembling,” Rika murmured. “Do you want to stop?”
Mio’s answer was a whisper:
“…No…”
“Then let your big sister take care of her kitten.”
Mio melted into her, tail again seemingly twitch behind her, the bell jingling softly as Rika laid her back and began to explore her — slow, sweet, and sure.
