Shin's hands didn't stop roaming even as Ai clung to him, breathing fast, face buried against his chest.
But he wasn't done with her.
Not even close.
A wicked glint flashed in his eyes.
"Ai..." he murmured, voice low, vibrating against her skin.
She barely had time to squeak in surprise before he shifted, grabbing her hips and pushing her gently but firmly down onto the slick, warm tile floor.
He positioned her on her hands and knees, the hot water still raining over them.
"O-Onii-chan?" Ai gasped, heart hammering as she felt the vulnerable position he put her in — back arched, ass high in the air, fully exposed to him.
"You're perfect like this," he growled, voice thick with hunger.
Ai trembled under his gaze, feeling his eyes devour every inch of her flushed, dripping body.
And then—
He reached out and spread her cheeks apart with both hands, exposing her most private places completely to him.
Ai whimpered, burying her face in her folded arms, utterly overwhelmed by the shameful thrill of it.
Shin's breath was hot against her newly exposed skin.
"You're shaking, little sis," he teased, voice dark with amusement. "Are you scared?"
Ai shook her head frantically, though her body trembled like a leaf.
"No…! I want it… Please…!"
Her desperate little voice made something inside him snap.
Without warning, Shin leaned in —
And dragged his tongue slowly, obscenely, over the tight, puckered hole of her ass.
Ai shrieked — a high, helpless sound — her arms buckling slightly from the shock.
"O-Onii-chan!! Ahn!!"
He chuckled low in his throat, a dark, pleased sound.
"You like this, don't you?" he murmured against her skin, his hot breath making her shudder violently.
Ai could only nod frantically, her mind blank with shame and unbearable pleasure.
Shin licked her again, slower this time, flattening his tongue against her sensitive entrance and dragging it up firmly.
Ai sobbed into her arms, her body twitching with every flick of his tongue.
Her thighs shook violently, slick with her arousal and the steaming water cascading over them.
"Onii-chan... it's embarrassing...!" she whimpered, voice breaking.
"Good," Shin growled.
He spread her wider, thumbs pressing firmly into the soft flesh of her ass, keeping her open for him.
Then he pressed his tongue more insistently against her tight hole, licking in firm, slow circles.
Ai's hips jerked helplessly, but Shin only held her tighter, relentless.
He sucked on her rim gently, teasing it with the tip of his tongue, making Ai sob and moan incoherently.
She felt like she was going insane —
The filthy pleasure was short-circuiting her brain.
"O-Onii-chan...! I'm gonna—!" she cried.
Shin smirked against her skin.
He dipped the very tip of his tongue inside, just barely breaching her tightness.
Ai screamed.
Her climax hit her like a freight train —
Full-body, devastating, making her collapse face-first into the tile, trembling uncontrollably.
Shin pulled back slightly, admiring the way her body spasmed and twitched under him.
"That's it," he praised darkly, running his hand soothingly down her back. "Cum for me, Ai. Show me how much you love it when your big brother makes you lose your mind."
Ai whimpered weakly, unable to speak, her face burning hot with shame and ecstasy.
But Shin wasn't finished.
Not even close.
As Ai panted for breath, trying to recover, he knelt behind her again, spreading her sore, quivering cheeks even wider.
"Still not enough," he muttered hungrily.
He dove back in, tongue fucking her tight little hole, licking deeper now, wet and filthy and obscene.
Ai sobbed into the tile, her hands clawing uselessly at the wet floor.
Her whole body felt like it was melting, her mind blank and white-hot with sensation.
Shin growled lowly, feeling her clench and spasm around his tongue, tasting her sweetness, savoring the way she writhed under him.
"You're so fucking perfect, Ai," he hissed between licks. "I could eat you forever."
Ai could barely even process his words anymore —
Every nerve ending was on fire, every thought drowned by the relentless pleasure he was giving her.
When he finally pulled away, her hole glistened with spit and arousal, twitching slightly from the abuse.
Shin wiped his mouth with the back of his hand, eyes dark with lust.
He leaned over her trembling body, kissing the nape of her neck.
"You did so good, Ai," he whispered roughly.
He gathered her into his arms again, cradling her tenderly against his chest.
"I love you," he whispered into her wet hair.
"I love you too, Onii-chan," Ai murmured back, already half-asleep against him.
And as the water continued to fall around them like gentle rain, Shin held her close —
His, completely and utterly.
Forever.
---
The bathroom door creaked open, a puff of lingering steam escaping into the hallway like a guilty secret.
Ai stumbled out first, still toweling her damp hair, cheeks burning an impossible shade of red.
She wore a simple T-shirt and a cotton shorts that clung slightly to her still-damp skin.
Behind her, Shin followed, looking maddeningly normal — freshly showered, hair still wet, a clean black T-shirt stretched across his broad chest, and simple gray sweatpants hanging low on his hips.
The contrast between them was almost laughable.
Shin looked calm.
Collected.
Barely even mussed.
Ai, however—
She looked completely and utterly ruined.
Her legs wobbled slightly as she shuffled forward, almost limping.
Her face was flushed pink from forehead to chin, her eyes glazed, her lips swollen and glistening as if she'd spent way too long kissing.
And her hair — despite her frantic toweling — was still sticking up messily in places, wild and tangled from where Shin's fingers had threaded roughly through it.
She looked like she had been thoroughly — utterly — ravished.
And worse, she looked like she had loved every second of it.
"Come on, Ai," Shin said casually, as if nothing at all had happened. He gently placed a hand on her lower back, guiding her forward. "You said you'd cook."
Ai squeaked, the tiny sound escaping her without permission, and ducked her head lower, trying desperately to hide her face behind the towel.
"R-Right! Cooking!" she squeaked, voice way too high-pitched to sound normal.
Unfortunately for them, the path to the kitchen led them right past the living room —
Where Rika and Yuki sat sprawled across the couch, playing some mobile game together.
Or at least, they had been playing.
Now both of them sat frozen mid-motion, staring at the scene in front of them with wide, disbelieving eyes.
Yuki was the first to react.
He blinked once, slowly.
Then again.
Then he turned his wide, suspicious gaze to Rika —
Only to find her looking just as stunned, mouth slightly open in an expression halfway between horror and horrified fascination.
"Uh…" Yuki started.
"…" Rika made a strangled sound.
Neither Ai nor Shin said a word.
They just kept walking —
Shin casual and composed, Ai doing her best impression of a turtle retreating into its shell —
As if they could somehow pretend the two witnesses on the couch didn't exist.
It didn't work.
Not even close.
As soon as Shin and Ai disappeared into the kitchen, Rika dropped her phone onto the couch with a loud thud and whirled toward Yuki.
"Did you SEE that?!" she hissed, voice strangled.
Yuki nodded slowly, his fingers twitching in his lap.
"Yup," he said blankly. "I saw it. I wish I hadn't, but I did."
Rika buried her face in her hands and groaned loudly.
"They're totally doing things," she moaned.
"They're definitely doing things," Yuki agreed solemnly.
"And not just kissing things!" Rika added, voice rising hysterically. "Did you see Ai's face?! She looks like — like — like someone who just spent an hour getting—"
"Rika!" Yuki yelped, clapping a hand over her mouth, his own face turning crimson. "Don't say it!!"
Rika mumbled indignantly against his palm, then pried his hand away.
"I mean, come on, Yuki!" she whined. "Her lips were swollen! Her legs were shaking! She couldn't even walk straight!"
Yuki groaned, slumping back against the couch like a man who had seen too much.
"And Shin..." Rika continued, voice dripping with dramatic agony. "He looked so... so smug! So satisfied!"
Yuki groaned louder, covering his face with both hands.
"And Ai..." Rika's voice dropped into a jealous whine. "She's so cute. Her skin is so soft and smooth... like a perfect little doll... and now Onii-san gets to kiss her and touch her whenever he wants...!"
Rika's fists clenched at her sides, her whole body shaking with injustice.
"I hate it!" she cried dramatically. "I hate it so much! Why does he get to have her?! Why is he so lucky?!"
Yuki patted her shoulder sympathetically.
"And don't even get me started on him," Yuki muttered under his breath. "That stupid, handsome face... Those arms... Those abs... Ugh. It's not fair."
Rika blinked at him.
"...You sound kind of jealous too," she pointed out.
Yuki flushed even deeper.
"It's not like I'm jealous of Ai touching him or anything!" he blurted defensively. "It's just... ugh, he's so hot, okay?!"
Rika snorted.
"Not like I'm jealous or anything," she mimicked in a mocking high voice. "Not like I want to run my hands all over his stupidly muscular body and kiss that smug, handsome face or anything—"
"Rika!!" Yuki wailed, burying his face in the cushions.
Rika cackled evilly, basking in his embarrassment for a moment before slumping back against the couch.
They sat in silence for a few seconds, both stewing miserably in their own jealousy and self-pity.
From the kitchen came the sounds of clinking dishes and low, murmured voices —
And every now and then, a soft giggle from Ai or a low chuckle from Shin.
It was torture.
Absolute, pure torture.
"They're definitely enjoying themselves," Rika muttered bitterly.
"Definitely," Yuki agreed glumly.
"I bet he's touching her even now," Rika grumbled. "Sneaking little kisses, grabbing her butt, pressing her against the counter…"
Yuki whined piteously.
"I bet she's running her hands all over his abs," he moaned. "Touching that stupidly perfect chest… while he grins like he owns the world…"
Rika made a dramatic gagging noise.
"I hate them," she announced. "I hate how happy they are."
Yuki nodded solemnly.
"Same," he said.
Another giggle floated from the kitchen.
Rika growled low in her throat.
"Traitor," she muttered under her breath, glaring daggers at the doorway.
Yuki reached over and patted her knee sympathetically.
"We'll survive this," he said solemnly. "Together."
Rika sniffled dramatically and nodded.
"Yeah," she agreed. "We have to. For the sake of our dignity."
Yuki wiped an imaginary tear from his eye.
"For our pride," he said gravely.
They sat there, side by side, mourning their collective romantic misfortune like two soldiers sharing a trench in a hopeless war.
It would have been a touching scene.
If not for the loud, unmistakable sound of Ai's giggles turning into squeals as Shin — no doubt — tickled her mercilessly in the kitchen.
Yuki and Rika twitched.
Their eyes met.
And in perfect, wordless synchronicity, they both let out identical, miserable groans and slumped face-first onto the couch cushions.
This was their life now.
And it sucked.
