It was just past three in the morning when Shin stirred.
The room was quiet, cloaked in darkness save for the soft amber glow of the bedside lamp he'd forgotten to turn off. Ai lay naked against him, her body molded perfectly to his side, one of her thighs draped across his lap beneath the blanket. Her breath was warm on his chest, her hand curled under her chin as she slept, skin flushed from their earlier lovemaking.
He stared down at her with a quiet smile. Peaceful. Vulnerable. Completely his.
Shin leaned down, pressing a gentle kiss to her forehead. "Ai… baby, wake up for a sec."
"Mmm… Onee-Chan…" she murmured, eyes fluttering open, lips parting with a soft yawn. "It's still dark…"
"I know. I'm gonna call the others. Thought you'd wanna say hi too."
"…Yuki and Haa-Onee-Chan?" she asked, sleepily shifting under the blanket. The motion caused the fabric to slide over her bare curves, exposing her shoulder and making Shin's eyes darken for a second.
"Yeah. Figured we'd surprise them."
She smiled faintly, wrapping the blanket tighter around herself. "I'll stay under here. Too cold to get dressed."
"Not that I mind," he whispered, kissing her cheek. "Stay right there, babe."
He reached for his phone from the nightstand and quietly started a group video call in their chat, "Our Chaotic Love Nest." Their group photo popped up—Aiko's peace sign and tongue-out grin, Yuki's beet-red scowl holding a bento, and Shin grinning like a proud idiot between them.
The screen buzzed.
Aiko answered first.
"Taa-Kun!! Why the hell are you calling at three—ohhh my god, don't tell me—wait, you missed me already, didn't you?!"
He grinned. "I did. But that's not the only reason."
Then the second screen loaded—Yuki's camera flicked on, showing him rubbing his eyes, hoodie drooping off one shoulder, white hair adorably messy.
"…Shin? You bastard… it's 3am. Are you drunk?"
"Drunk in love, maybe," Shin said with a sleepy smirk. "Had to see my beautiful girlfriend and cutest little tsundere before I pass out."
"W-What?! I—D-Don't just say that out of nowhere, idiot!" Yuki's cheeks flushed instantly.
Aiko cackled. "Yuki-chan~ you're so weak to compliments. I love it! Look at that messy bedhead. I wanna squish your cheeks!"
"Sh-Shut up! I'm not squishy!"
"You are! I could eat you up. You look like a plush toy that learned to talk!"
Shin interrupted with a sly smile. "Guys. Focus. I've got something to show you."
Both froze as he slowly turned the phone, angling it toward the other side of the bed.
Asahi.
The little boy was sprawled on his stomach, shirt riding up his back, blanket kicked off completely. His tiny limbs stretched out like a sleepy starfish, and his soft breathing filled the silence.
Aiko gasped.
Then squealed so loud Shin winced.
"A-CHANNNNNNN!!!" she screamed. "TAA-KUN! IS THAT MY A-CHAN?! OH MY GOD! LOOK AT HIM!! HE'S STILL TINY!!"
Shin chuckled. "Yeah. That's Asahi. Still obsessed with me. Still adorable."
"I was there when he was born!" Aiko gushed, hands to her cheeks. "I named his first plushie! Remember, Taa-Kun?! The bear with one eye?!"
"Of course I do," Shin grinned. "You told me it was 'cooler that way.'"
Yuki blinked slowly. "Wait. You have a brother?"
"…I told you yesterday," Shin said.
"No you didn't!! That's crucial info!"
"I've known you a week."
"That doesn't matter!" Yuki huffed.
Aiko leaned in, glowing. "I'm bringing him strawberry gummies and melonpan and a new plush dragon and a baby shark hoodie and—"
Ai's voice drifted up from the blanket, sleepy but annoyed. "Ugh… he's not even that cute."
The camera shifted—Ai peeked out from under the blanket, her hair a wild mess, face flushed, clearly still naked beneath the covers.
Yuki and Aiko froze.
Their faces turned red at the exact same time.
"…Y-You're—She's—" Yuki stammered.
Aiko covered her mouth. "No way… you two did it again tonight?!"
Ai yawned. "You're acting surprised. We always do."
Shin kissed the top of her head with a satisfied grin. "Can you blame me?"
Yuki looked like he might combust.
Aiko groaned dramatically. "You two are the worst. Do you know how jealous I am right now?! You're lying in bed, naked, all post-sexy glow, and meanwhile I'm here in my pajamas with bed hair and NO ONE TO CUDDLE!"
"I mean…" Shin drawled, "You could come over. Both of you. First thing in the morning. No excuses."
Ai smirked from under the blanket. "I dare you."
Yuki narrowed his eyes. "I'll do it. I'll be there."
Aiko threw a peace sign. "With snacks. And extra hugs for A-chan!"
Ai rolled her eyes. "He doesn't need your snacks. He already acts like Onii-Chan belongs to him."
"He does!" Aiko teased. "You're just jealous because A-Chan's the clingiest, most adorable little sibling ever. He literally used to fall asleep on Taa-Kun's face!"
Ai muttered, "He still tries…"
Shin snorted. "He's got competition now."
Then, as if to drive it in, he turned back toward Ai and dipped beneath the blanket. Ai gasped, arching slightly.
"O-Onii-Chan…!" she hissed.
He kissed her neck slowly, his free hand trailing under the blanket to grope her breast and then her hip, making her squeak. "Mmm… still sensitive?"
"Y-You can't—mm—do that while they're watching…!"
Aiko's jaw dropped. "SHIN!"
Yuki's face turned crimson. "YOU'RE TOUCHING HER RIGHT NOW?!"
Shin glanced back up with a wicked grin. "Just wanted to give you both a little motivation for tomorrow."
Ai whimpered, covering her mouth. "You're evil…"
"Say you love me, then."
"I love you, idiot," she pouted, cheeks red.
Aiko slammed her pillow. "I'M GOING TO BE THERE AT DAWN!"
Yuki crossed his arms, but his eyes betrayed his flustered smile. "Fine. I'll come too. But I'm sitting next to you. And I get at least five hugs. Minimum."
"Seven," Shin corrected, smug.
"Ten!" Aiko added.
Shin laughed. "Okay, okay. Just don't kill each other over me."
Yuki grumbled, "Not making promises."
Ai reached out, pulling Shin back into the blanket, her voice sultry and smug. "Don't make it too obvious how much you want him tomorrow…"
Aiko groaned again. "I hate how good you two look together. I hate it. I'm gonna make you jealous tomorrow, Ai!"
"Try," Ai grinned.
"Game on," Aiko smirked.
