Warm steam curled around the glowing tiles like a veil of secrets, soft and heady. The oversized loofah flopped to the side with a wet splat, finally released from Asahi's tiny grip as he finished his duty with an exaggerated sigh.
"There!" he declared, proudly brushing his wet bangs out of his eyes. "All done, Yuki-Nii! You're squeaky clean now!"
Yuki, cheeks still glowing as pink as his soaked skin, hunched forward slightly on the bath stool. "Th-thanks... I guess…"
He tried to hide the way his body was trembling, whether from the heat or embarrassment, he wasn't sure. Steam clung to his lashes. His delicate voice nearly cracked as he muttered, "I'm never letting you do that again…"
But Asahi just grinned, hopping away like an excitable puppy. "Now it's Amu-Chan's turn!"
Aiko immediately bounced up with enough enthusiasm to jiggle in five directions at once. "YAY~!" she sang, hopping into place with a huge smile on her flushed face. "Scrub me! Scrub me!"
She dropped onto the stool with a loud, wet plop, sitting with her back straight and breasts bouncing as they settled in front of her. Her hair was soaked and clinging to her neck, but her eyes sparkled with the pure joy of a spoiled cat-girl.
Asahi giggled, grabbing the loofah with both hands again. "You're big everywhere!"
Aiko looked over her shoulder with a smug grin. "I know, right? Wanna marry me so you can touch them forever?"
Asahi blinked, then grinned impishly. "Nope! I'm marrying Onii-Chan first!"
Aiko gasped, placing a hand on her chest like he'd just stabbed her. "You traitor! I'm gonna marry him too, you know!"
"But I said it first!"
"You little homewrecker…" Aiko stuck out her tongue before adding, "Fine! Marry Shin—but you're still mine. I need your tiny hands to wash me every night!"
Asahi blushed and giggled, continuing to scrub her back with enthusiasm. "You're really squishy, Amu-Chan!"
"Mmm~ Keep praising me, I might let you sleep in my bed~"
Across the room, Yuki sank a little deeper into his own towel, trying to disappear from the overwhelming chaos of the moment. His ears were red now—very red.
"They're both insane," he muttered, then turned to glance back at the tub.
And froze.
Ai was still curled in Shin's lap, but now their lips were locked in a slow, breathless kiss. Her arms were wound tight around his neck, their bodies tangled like ivy. Their mouths moved together with an intimacy that made Yuki's stomach clench. The heat of the bath did little to hide the possessive way Shin's hand stroked Ai's bare waist just under the surface.
Yuki swallowed hard. They just... right before this...
He could feel it. The depth of the way Ai leaned into Shin, the way her body clung like she was still trembling from aftershocks. Her toes curled under the water. Shin's hand never moved above the surface—because it was still likely holding onto the same place he'd been gripping earlier.
Yuki blushed violently, suddenly remembering—before the bath—when Shin had pulled him aside to his room, gently locking the door while the others were laughing in the living room. His soft hands, his warm mouth trailing lower, and then—his fingers. The way they'd stretched and teased Yuki's hole until he was a melting mess, biting his wrist just to muffle the moans.
And now, Ai had gotten the real thing.
"P-pervert…" Yuki muttered to himself, legs wobbling as he forced himself to stand.
He padded across the slick tile slowly, half out of curiosity, half out of nervous need.
Ai was giggling now, whispering something into Shin's ear. He responded with a soft chuckle and a kiss to her temple. They both looked up when Yuki arrived—wet, nervous, and fidgeting.
"There's our shy one," Shin teased with a low smile.
Ai beamed. "Yuki! You finally came to join us~"
"I-I didn't come here to get involved with your indecent—AH!" he yelped as Shin suddenly reached out and grabbed him by the wrist, tugging him into the water with an effortless pull.
Yuki stumbled, landing hard against Shin's side. "W-what are you—!?"
"You looked lonely," Shin said simply, slipping his arm around Yuki's waist under the water.
Ai giggled and leaned in again, pressing her soft body against Shin's other side. "Don't worry, Yuki~ We've got enough love to go around."
"D-don't say it like that! I'm a guy, remember!? The only straight one here!"
Shin smirked and leaned close, whispering against Yuki's flushed ear. "Straight guys don't moan like you did an hour ago…"
Yuki's breath caught. His whole face burned.
"B-baka! Shut up!"
"I love when you say that," Shin chuckled—and then he kissed Yuki.
The kiss was slow and deep, his lips teasing Yuki's as his hand slid around to cup the back of his neck. Yuki trembled, squirming, his tsundere resistance melting fast. Then—pinch.
"Ahh!!" Yuki squeaked, arching as Shin's other hand found one of his nipples under the water, tugging gently.
"Ohh, he's sensitive today," Ai hummed, watching with a sparkle in her eye.
"Stop! Don't touch there, you freak!" Yuki growled—but then gasped again as Shin's grip tightened around his ass.
"Mm, still nice and soft… And clean, thanks to Asahi," Shin added with a smirk.
Yuki's arms slapped weakly against Shin's chest. "Stop touching me like I'm your—"
"You are, Yuki," Ai purred, planting a kiss on Shin's neck while pressing her breasts against his side. "You're our cute little girlfriend-boyfriend."
"I-I'm not—!"
"Oh?" Shin's fingers squeezed Yuki's butt firmly. "Then what should I call this?"
Yuki nearly exploded. "PERVERT!!"
From the side of the bath, giggles echoed like mischievous bells. Asahi and Aiko were watching now, lounging in their own bubbly corner of the giant tub.
"Look at Yuki-Nii squirm! But why is he squirming?" Asahi giggled, kicking his feet.
Aiko laughed with a wicked grin. "Because he's secretly the cutest."
Yuki screeched. "STOP LISTENING!!"
Shin laughed out loud, hugging Yuki closer, burying his face in the boy's neck. "Aw, don't be mad. I'll make you feel good later to make up for it."
Yuki stammered, "Y-you already—!"
Ai's mouth met his again, cutting him off.
The kiss was soft this time—tender. Her lips moved slowly, soothing, while her fingers stroked his damp bangs from his face. When she pulled away, she whispered gently, "You're important to us, Yuki. Don't run away, okay?"
Yuki looked like he was about to cry. Or punch something. "I'm not running… I'm just… you're all insane..."
Shin kissed his cheek. "But you love us."
"...B-baka…"
They melted into the water, tangled in warmth and laughter, their bodies pressed close, their hearts thudding together under the surface. Even amid the chaos, the teasing, and the heat, there was something tender at the center of it all.
And in the background, Asahi and Aiko were already plotting something devious for later.
