The moment Asahi announced with childlike glee that he was going to poop, the room burst into soft chuckles. He ran off from Aiko's lap and disappeared around the corner toward the washroom, little footsteps echoing down the hallway.
And just like that, Shin's smirk deepened.
From his throne on the couch, still lounging like a king with Ai curled at his side and Yuki snuggled on the other, Shin turned his head lazily toward Aiko. His eyes gleamed with wicked intent.
"Haa-Chan."
Aiko looked up from where she sat, blinking with a playful spark in her gaze. The nickname melted on his tongue like honey.
"Hm? Taa-Kun~?"
He crooked a finger, beckoning. "C'mere."
Aiko's lips twitched into a knowing smile. With a soft, sultry giggle, she got to her hands and knees and began crawling slowly toward him. Each movement was deliberate, teasing. Her long hair spilled forward like silk curtains, her tank top low enough to display the soft swell of her cleavage with every sway.
"You calling me over like some kitten, Taa-Kun?" she purred.
Shin grinned. "Well, you are a cat girl, aren't you?"
"Nyaa~" she teased, licking her lips as she approached.
Ai shifted slightly, eyes half-lidded, watching curiously but too blissed out to move. Yuki flushed but didn't say a word, cheek still pressed into Shin's shoulder, peeking.
Aiko climbed onto the couch, hovering just above Shin's lap. Her knees on either side of him, she leaned down slowly. Her chest brushed against his as her hand rested on his chest, fingers curling into his shirt. Their faces met halfway.
Their lips crashed together with a spark.
It wasn't slow. It wasn't gentle. It was hungry.
Aiko let out a soft moan as she deepened the kiss, grinding her hips gently as she settled into his lap. Her other hand cupped his cheek, fingers curling possessively around his jaw.
Shin's hands slid down to her thighs, squeezing them as his tongue explored her mouth. Heat poured from them both, and for a moment, the entire world melted into the kiss.
When they finally pulled away, breathless, Shin chuckled against her lips.
"You really like teasing me with those boobs, huh? Letting Asahi stuff his whole face in them during the bath."
Aiko blinked. Then, she grinned.
"Oh? Jealous, Taa-Kun?"
He nipped her bottom lip. "I'm just saying, those are mine."
She giggled. "Asahi was just having fun! You let Ai do whatever she wants with your body, and Yuki's been nibbling your neck for the last hour. You're the one to talk!"
Yuki's face burst into crimson. "I-I was not nibbling!"
Shin turned slightly, grinning. "Kiddo, your lips are literally still on me."
Yuki squeaked and turned away, burying his face in Shin's arm.
Ai giggled, tugging gently at Shin's shirt. "You do have a point, Onii-chan."
But Shin turned his attention back to Aiko. He slid a hand up, cupping her breast through her top, fingers firm.
"These, though," he murmured, "are mine. Not Asahi's. Not even yours. Mine."
Aiko gasped, face flaring red.
"T-Taa-Kun!"
He leaned up and kissed her collarbone, lips trailing warm and slow.
"Just reminding you."
She let out a shaky breath, leaning into his touch.
"You're so possessive..."
"And you're so damn soft."
She grinned wickedly, fingers trailing down his chest. "Then claim them. Again."
Shin didn't need to be told twice. He kissed her again, deeper this time, tilting her head back with one hand and pulling her close with the other. The moment burned like fire, but with that same warmth that made them both melt.
Ai and Yuki, both still leaning against him, didn't protest. Ai only watched with lidded eyes, lips parted, while Yuki peeked once before groaning and covering his face with both hands.
"Idiot couple," he muttered.
Shin pulled away just long enough to smirk and say, "You love it."
Aiko giggled, curling into him now, wrapping her arms around his shoulders. Her voice lowered to a whisper only he could hear.
"You really get off on me being yours, huh?"
"Only when you prove it again and again."
"Then let me prove it, Taa-Kun."
Aiko's lips stayed locked with Shin's, her body melting into his touch, her heartbeat stammering in her chest. The weight of her words still hung in the air between kisses.
"I love you," she whispered again, her voice trembling like a fragile ribbon of wind. "I've loved you since we were kids, Taa-Kun…"
And she meant every syllable.
Her confession wasn't a sudden outburst, not some fleeting whim stirred by heat. It was the quiet truth that had lived in her chest for years—long before kisses, long before their bodies grew into the longing that now swirled between them.
Shin stilled.
For just a heartbeat, he froze beneath her—his breath caught, his lips hovering against hers as his eyes opened.
Her face was so close, flushed and trembling, but her gaze was unwavering.
And then—
Shin kissed her again.
This time slower, deeper.
There was no rush, no hunger, just something else entirely—like he was swallowing her words and tucking them inside himself. Like he was answering her confession not with more words, but with the language they'd grown to understand so well: touch.
His hands slid up.
From her thighs, warm beneath his palms, to the hem of her tank top. His fingers slipped under the fabric, brushing the bare skin of her belly, trailing upward slowly, as if savoring every inch. He could feel her shiver against him, her breath stuttering as his palms moved higher.
Aiko gasped softly when his hands reached her chest.
Her breasts were bare beneath the tank top—she hadn't bothered with a bra, and now she was acutely aware of just how thin the fabric really was. Shin's hands cupped her gently at first, reverent almost, as if testing the reality of what he was holding.
Then his thumbs brushed across her nipples, and Aiko let out a soft, helpless whimper.
"T-Taa-Kun…"
He didn't answer.
His lips trailed down, from her mouth to her jaw, then to the soft slope of her neck. He kissed her there, slow and possessive, while his fingers continued to knead and pinch, rolling her sensitive buds between his fingers.
Aiko's body arched into his touch, her hands tightening in his shirt.
Her tank top rode up further with every motion, bunching beneath her chest until it was barely a suggestion of clothing anymore. Shin tugged it up over her head without a word, and she let him—eyes fluttering, cheeks burning, heart thundering.
When her breasts were finally bare to him, Shin pulled back just enough to look.
And then he smiled.
Not a teasing one this time. Not a smirk.
But something softer. Something real.
"…Beautiful," he whispered.
Aiko flushed so deeply she thought she might pass out. "D-Don't look like that…!"
She was embrassased now even though they had seen each other like this countless time since childhood and baths.
"I'll always look," he murmured, hands returning to her chest. "Especially when they're mine."
She squeaked as he pinched gently again, tugging just enough to make her hips twitch.
Her core—already pressed against the firm line of his erection beneath his shorts—throbbed at the pressure. Even through her short skirt, she could feel the heat of him, the pulse of his length resting directly between her folds.
She rubbed against it without thinking, slow and instinctive, her body moving in gentle rhythm.
Shin groaned softly into her neck. "You're soaking through…"
Aiko bit her lip, hiding her face against his shoulder. "Y-You're so mean…"
"Not mean." He pinched her again, firmer this time. "Just honest."
Her moan escaped before she could stop it.
She didn't even try to pretend anymore. She rocked against him gently, body trembling, her chest heaving with every breath. Shin's hands never stopped—alternating between squeezing and teasing, one hand slipping down every so often to grip her waist, guiding her grinding motion against him.
"You've always loved me?" he asked suddenly, breath warm against her ear.
She froze, blinking.
"…Since when?"
Aiko hesitated, then lifted her gaze. Her eyes shimmered, vulnerable and brave all at once.
"Since the day you walked me home after I fell and scraped my knee in second grade," she whispered. "You held my hand the whole way and told me I didn't need to cry. That you'd cry for me if I wanted to keep my tears…"
Shin blinked.
"That's stupidly cute."
"I was a stupidly cute girl," she huffed, cheeks puffed.
He chuckled—and leaned in to kiss her again.
"I love you too, Haa-Chan."
Her eyes widened.
The world tilted.
Everything stopped, suspended in a single breath.
And then Aiko broke. A soft sob bubbled in her throat, though she didn't cry. She just clung tighter, pressing her forehead against his, kissing him again, over and over, each kiss messier than the last.
"I thought I'd lost you," she whispered between gasps. "I thought… I waited too long…"
"You didn't."
"But Ai—Yuki—"
"—love me too," Shin said gently. "And I love them. But that doesn't make what we have any less real."
He shifted beneath her, letting her feel his length more directly now. Her skirt slid up further with the movement, the fabric now barely a barrier between them.
"And right now," he whispered, "you're the only one I see."
Aiko let out a soft, broken sound.
Her fingers trailed down his chest, then lower, brushing the waistband of his shorts. She hesitated, nervous, trembling.
"I… I don't know what I'm doing," she admitted, her voice barely a breath.
Shin kissed her shoulder, slow and warm. "You don't have to do anything you're not ready for."
"I want to," she whispered. "I'm just scared."
"Then let's not go further tonight," he murmured. "I'll still hold you. I'll still kiss you."
"…But my body wants you," she said shakily. "Even if I'm scared."
His hands returned to her chest, soft now, like a silent promise.
"Then we'll listen to your body," he said. "But only what it's ready for."
She nodded.
And so, their lips found each other again—slow and intimate. Shin's hands returned to her breasts, massaging gently as Aiko's hips resumed their soft grinding. Her folds slid along the length of his arousal through the fabric, slick and warm. Every rub drew out another breathless moan, another quiet gasp that spilled against his lips.
Her thighs trembled. Her nipples stiffened even more under his touch. She clung to him, hips stuttering now, her body dancing closer to the edge she'd never known before.
"Taa-Kun," she whispered, voice breaking.
"I'm here."
"I… I think I…"
He kissed her again, and that was all it took.
Aiko's body shook as she pressed down hard against him, her folds tightening around nothing, her climax sudden and sharp like lightning splitting through her chest.
Her moan broke free, muffled against his lips.
And then she collapsed into his arms, trembling, flushed, and panting, her face buried in his neck.
"I-It felt like my heart exploded," she mumbled.
Shin chuckled, wrapping his arms around her, holding her tightly. "Good. That's how it's supposed to feel."
"…I love you so much it hurts."
"I'll hold all of it," he said gently, running fingers through her hair. "Your love, your pain, your heart. It's mine too."
She melted.
And for the next few minutes, they stayed like that—just holding, kissing, sharing quiet, breathless whispers of promises neither of them needed to say aloud.
Because they were already written all over their bodies.
And in the way their hearts had always, always belonged to each other.
