Chapter 90The front door clicked softly shut behind Rika and Yuki. Their scents still lingered in the hallway like an echo—sweet, warm, fleeting.
Ai stood beside Shin, smiling, hands folded behind her like an innocent schoolgirl, though her mind swirled with anything but innocence. She rocked on her heels, her pink nightdress brushing lightly against her thighs. The morning sun bathed the corridor in gold.
"She said she loves you," Ai muttered, puffing her cheeks and looking sideways at Shin.
"I know." Shin chuckled softly. "She doesn't hide things well."
Ai squinted up at him with a pout, hands dropping to her hips. "You didn't say it back."
Shin turned, closing the distance between them. "Because the one I love is standing right here."
Ai's cheeks reddened instantly. "H-Hmph... you better."
Before she could say more, Shin wrapped his arm around her waist and pulled her close. Their lips met in a slow, hungry kiss—one that melted frustration and stoked a deeper need that had simmered under the surface all morning.
"Mmm... Onii-chan," Ai breathed against his mouth.
Shin didn't reply in words. His hands slid down her back, cupping her thighs as he lifted her effortlessly. She gasped and wrapped her legs around his hips, fingers threading into his hair.
Still kissing, they stumbled their way to the bedroom—Shin's bedroom, where his scent filled the air with every step. The moment the door clicked behind them, urgency took over.
Shin dropped her onto the bed, and Ai bounced softly with a giggle, her hair falling wild around her shoulders.
"I missed this," she whispered.
"I missed you," Shin answered, already climbing over her, their eyes locked.
Ai tugged at his shirt, her breath hot, cheeks flushed. "Take it off. I want to feel you again."
One by one, their clothes came off. His shirt landed on the floor. Her nightdress was lifted and tossed aside, revealing her soft, eager skin. Their hands roamed without hesitation, relearning familiar curves and delicate lines.
Shin leaned down, kissing the side of her neck, just below her ear. "You're still warm from last night."
Ai moaned softly, her thighs parting instinctively as she pulled him lower, their skin now bare and pressing close. "I was thinking about you all night."
Shin hovered just above her, his arms braced beside her head. "Even while I was with Rika?"
Ai's lips curled slightly, a mischievous smirk dancing on her face. "Especially then."
Their mouths met again, deeper this time. Tongues entangled, breathing quickened, and heat spread between them like wildfire.
Shin pressed against her, grinding slowly with purpose, eliciting a soft cry from Ai's lips.
"Tell me," she said, voice low and trembling. "What did you do with Rika last night?"
Shin paused only a moment. "We kissed. Then I held her while she slept."
Ai closed her eyes. Her arms wrapped around him tightly. "You touched her hair?"
"Yes."
"Held her like this?"
Shin nodded once.
Ai sighed, a mixture of frustration and arousal. "She's my best friend."
"I know."
Ai opened her eyes. "So you know I can't let that slide."
Shin raised an eyebrow, amused. "What's my punishment?"
Ai's lips curled into a slow, seductive smile. "You have to love me," she said, pulling him down, their bodies flushed against each other.
"All day," she whispered, kissing his jaw.
"All night," she added, nipping at his earlobe.
Shin's breath hitched. "That's not a punishment. That's everything I want."
"Good." Ai cupped his cheek. "Then don't hold back. Show me."
Shin's lips reclaimed hers, urgent now, deeper than before—no longer just hungry, but starving. Ai responded with matching intensity, arms clinging to his neck as she pulled him on top of her. Their bare skin pressed together, every inch electric with need.
He trailed kisses down her jawline, nibbling gently at her throat as Ai tilted her head to offer more. Her breath came in quick, soft gasps, especially when he reached her collarbone, his tongue dragging lazily across her flushed skin.
"You're so sensitive today," Shin whispered.
"I missed you," Ai whispered back, her fingers threading through his hair. "I've been aching since I woke up."
He smiled against her skin. "Then let me ease you."
Shin slid lower, lips trailing down the soft valley between her breasts. Ai arched under him, her back curving in response as her nipples tightened. He took one into his mouth, sucking gently at first—then harder when she whimpered.
"Ah... Onii-chan," Ai moaned, legs twitching beneath him.
His other hand came up, fingers skillfully pinching and rolling her untouched nipple, drawing soft cries from her lips with each twist. His mouth worked with practiced rhythm, tongue swirling and flicking, drawing out her gasps until she writhed beneath him.
"You taste just like I remember," he murmured, licking a stray drop of sweat from the side of her breast.
Ai's thighs squeezed around his waist. "You're not allowed to say things like that... unless you plan to make me melt."
"Oh, I do," Shin said, his voice low and teasing. "That's the punishment, remember?"
He kissed his way down her trembling belly, pausing to dip his tongue into her navel. Ai giggled breathlessly, squirming under his attention.
"Keep still," he said playfully, pressing a firm hand to her hip.
"I can't help it—"
She cut off with a yelp as he spread her legs wider, lowering his head between them. Shin ran his tongue slowly along her inner thigh, savoring the soft tremble that ran through her body.
"Your scent… still sweet," he murmured, kissing the sensitive crease where thigh met pelvis. "Did you get wet thinking about me?"
"Every time I closed my eyes," Ai whispered, cheeks flushed.
He answered with a long, deliberate lick over her folds.
Ai gasped—loud and sharp. "Ahh—!"
He didn't stop. His tongue moved with patience and precision, swirling over her clit, teasing the edges before dipping lower, tasting deeper. Ai's fingers gripped the sheets, then found their way into his hair, tugging with each flick of his tongue.
Her legs wrapped around his shoulders. "Onii-chan—please—ahh—yes…"
He licked faster, then slower, alternating between gentle teasing and sharp, focused pressure that had Ai moaning and trembling beneath him. When he dipped his tongue lower—circling her entrance—she nearly lost it.
But Shin wasn't finished.
He slid his tongue even further, down to the tight, forbidden ring below.
Ai's eyes flew open. "W-Wait..."
He didn't pause. His thumbs spread her cheeks gently, exposing her, and his tongue pressed against her most sensitive taboo. A shiver ran through her entire body, her hands flying to her mouth to muffle a shocked, desperate moan.
"Onii-chan—ahhh—what are you doing... that's so dirty..."
Shin didn't answer with words. His tongue pushed deeper, slow and careful, while his fingers resumed stroking her clit.
Ai bucked, her cries muffled by her hands, unable to hold still under the intense pleasure. "No one's ever—ahh—there—n-not there…"
"You're mine," he growled between licks. "Every part of you."
She whimpered, toes curling, hips jerking wildly as pleasure built in deep, intense waves. Her thighs trembled around his head, her voice a chorus of broken, breathless cries.
When she came, it was sudden and overwhelming—her body arching, back tight, mouth wide with a soundless scream.
Shin licked her through it, coaxing every last tremble from her until she collapsed into the bed, limp and shaking.
But Ai wasn't done.
She pulled at his arms, guiding him up. "Your turn."
Shin looked at her, a little breathless himself. "Ai—"
She silenced him with a kiss—deep, slow, tasting herself on his lips. Then she pushed him onto his back and climbed on top, eyes gleaming with mischief and desire.
"It's not fair," she said, crawling down his chest, her breasts dragging lightly over his skin. "You can't be the only one who gives."
Shin's breath caught as she reached his cock, now fully hard and glistening at the tip.
Ai wrapped both hands around the shaft, marveling at the weight, the heat. "You missed me too, didn't you?"
He groaned. "More than anything."
She leaned down and licked the underside slowly, from base to tip, then flicked her tongue over the head, teasing just beneath the ridge. Shin's head fell back with a moan.
"You're so sensitive," Ai giggled, then took him fully into her mouth.
Her pace was slow, savoring every inch. She hollowed her cheeks, sucking deep, then pulling back to tease the tip with her tongue. Shin's hips twitched, hands fisting the sheets.
"Ai… I might not last if you—ahhh—"
She popped him from her mouth with a grin. "Then don't hold back. I want all of it."
But she didn't stop there.
She swung her leg over his chest, positioning herself so her folds hovered just above his mouth.
"69," she whispered, cheeks pink. "Let me love you while you love me."
He didn't hesitate.
Shin lifted his head and latched onto her, his mouth seeking her clit again as she resumed sucking him. They moved in sync, moaning into each other, tongues working hungrily.
The room filled with wet sounds and stifled gasps, their bodies trembling from the intensity. Ai moaned around his cock every time his tongue hit just right. Shin bucked into her mouth with each flick of her tongue.
When Ai pulled off again, gasping, her voice was shaky.
"I'm gonna—again—Onii-chan—!"
Shin groaned, his own release close. "Me too…"
Ai slammed her lips down again, sucking hard as Shin gripped her hips tightly. They came nearly together—Ai shuddering, mouth full, swallowing eagerly as Shin's hips jerked.
They collapsed side by side, gasping for air.
For several moments, the room was silent except for their heavy breathing. The sheets were tangled beneath them, their bodies damp with sweat.
Ai rolled over, laying her head on Shin's chest. "That's only the beginning."
Shin chuckled breathlessly. "Only the beginning?"
"You promised," she said, poking his chest. "All day. All night."
He laughed softly. "I'll need water. And food."
Ai grinned, stretching like a cat. "I'll make you pancakes after round three."
"Round three already?"
"Mmhm." She propped herself up, straddling his stomach again. "You kissed my best friend. You don't get to complain."
Shin reached up, cupping her waist. "I'm not complaining."
"Good."
She leaned down, kissing him deeply again.
"I want to be sore tomorrow," she whispered. "I want to feel you even when you're not inside me."
Shin's fingers slid over her hips, gripping her. "I'll make sure of it."
"Love me, Onii-chan," she whispered. "Again."
And he did.
