Ai was still shaking in his lap, her face buried in his chest, body slick with sweat and flushed with warmth. But Shin didn't stop. He didn't even slow down.
His fingers slowly slid from her soaked folds, glistening with her release, and without hesitation, began drifting further back.
Ai stiffened in his arms.
"O-Onii-chan…?" she whispered, breath catching.
"Relax," Shin murmured, kissing the crown of her head. "Just trust me."
His hand slid lower, trailing through the mess of her arousal, down between the valley of her ass cheeks. She whimpered softly as his fingers found her tight ring.
"I want all of you," he whispered, his breath hot against her ear. "Even here."
Her body shivered. "That's…"
His thumb gently pressed against her back entrance, just enough to tease the rim, rubbing in slow circles.
He whispered firmly. "It's yours. So it's beautiful."
Ai's fingers clutched his arm, heart racing. Her legs instinctively tried to close, but his thigh pinned hers open, keeping her exposed beneath the blanket.
j,"Let me love you here, too."
His voice was calm. Steady. But there was heat behind it—raw, protective, possessive.
Ai whimpered, her voice barely audible. "…Okay…"
Using her own slickness still coating his fingers, Shin continued stroking over her tight star with slow, circling motions. Ai trembled in his lap, clinging to his arms as she felt the familiar but strangely erotic sensation overwhelm her.
"F-Funny…" she whispered, voice high-pitched and breathy.
He chuckled, pressing a light kiss to her cheek. "Ticklish?"
"Nngh… not just that…"
The blanket barely covered them now, riding low on her thighs. Her lower body was bare against his, the video call still live, though she could barely register it anymore.
Aiko moaned over the speaker. "He's… touching her there now, isn't he?"
"Oh fuck," Yuki whispered. "That's not fair… I wanna be her so bad…"
Ai's body jolted as Shin's thumb gently applied more pressure to her back entrance, still slow, still careful. The tight ring fluttered under his touch.
"Your body's already relaxing for me," he whispered. "See? You're letting me in."
Ai's breath hitched. "I-I feel weird…"
"Good weird?" he asked, curling his fingers to spread her slickness more evenly over the area.
She couldn't lie. Not to him. Not like this.
"…Y-Yeah…"
"That's my girl," he whispered, and with a slow, deliberate motion, he gently pressed his thumb inward.
Her entire body tensed—but only for a second.
Then, as he eased just the tip of his thumb past her tight ring, Ai gasped, her eyes wide, fingers digging into his arm.
"Breathe, baby," Shin soothed, kissing her again. "Nice and slow…"
Her body trembled as the feeling began to shift into something hot… invasive… and shamefully thrilling. She squirmed in his lap, overwhelmed.
"S-So full… but it's not even all the way in…"
"You're doing perfectly," he whispered, gently working his thumb in shallow, slow movements, massaging her inner walls. "You're letting me open you."
Ai cried out, her voice high and helpless.
"Onii-chan… oh god, it's… so good…"
On the screen, Aiko and Yuki had gone completely silent. The only sounds were Ai's panting, the faint squelch of Shin's slick fingers moving under her, and the ragged breaths of two very desperate spectators.
"She's trembling," Yuki finally whispered. "Is she…?"
"She's gonna come again, isn't she?" Aiko whispered. "Just from that?"
Ai was melting. Her whole body was shaking as Shin's thumb continued to press and swirl inside her, the sensation driving her to the edge.
"You feel this?" Shin said low in her ear. "You're clenching around me again. Your body likes it."
Ai could barely speak.
"Onii-chan… Onii-chan… I-I'm…!"
"Let it happen," he urged, his other hand moving to circle her clit again. "Come for me, Ai. Come from your tight little ass."
She exploded.
Her second climax hit harder—deeper—making her scream into his chest as her body convulsed in waves of hot, shuddering release. Her hips bucked helplessly in his lap, his thumb still buried in her tight hole, his hand still playing her like an instrument.
"Fuck," Shin groaned, feeling her twitching around him.
Ai sobbed his name as she fell limp in his arms, boneless and overwhelmed.
"I-It's too much… I can't… I can't move…"
He held her close, his own breathing labored now, his cock still hard against her back, untouched but pulsing.
"I've got you," he whispered, wrapping his arms around her. "I'll always have you."
Ai nestled into him, broken and blissful.
On the screen, Aiko and Yuki were crying and moaning in equal measure.
Shin smirked at them.
"She's mine," he said.
They both nodded dumbly, cheeks red, hands clearly still moving below the camera frame.
And Ai?
She only whispered, "Forever…"
---
Ai lay sprawled across Shin's lap, her legs draped over his thighs, blanket barely clinging to her hips. Her body was still trembling from the aftershocks, her mind swirling in a haze of heat, humiliation, and… pride.
Shin hadn't moved. His thumb was no longer inside her, but his hand still rested possessively on her bare ass, fingers idly tracing circles into her flushed skin.
Ai buried her face in his chest, peeking over just enough to glare—half-heartedly—at the glowing screen in front of them.
Aiko and Yuki looked wrecked.
Aiko's lipstick was smeared, her cheeks a bright red, her breaths shallow as she tried to pretend her hand wasn't still between her legs.
Yuki was just as disheveled, her boyish features flushed, collar stretched, eyes wide with envy and adoration.
Ai smirked lazily, her voice soft but teasing.
"You two still watching~?"
Yuki blinked. "W-Watching? I think I lived it…"
Aiko wiped her mouth with the back of her hand. "I'll never look at pancakes the same way again…"
Ai gave a weak little laugh, then shifted to sit up slightly. Shin helped her, steadying her back with one hand while the other casually brushed through her messy hair.
Still naked under the blanket, Ai tugged it up a little to cover herself—but not too much. She wanted them to see the flushed marks on her neck. The sweat on her chest. The way her legs still trembled.
"Do you guys see now?" she said, glancing between them with a smug little smile. "My Onii-chan's the biggest pervert ever."
Shin chuckled behind her, and Ai felt his smirk against her shoulder as he kissed her there.
Aiko leaned closer to the screen. "He put his thumb in your—"
"Yup," Ai cut in, cheeks pink but voice proud. "There."
Yuki groaned. "That's so unfair…"
Ai turned to look at her Onii-chan, narrowing her eyes. "He acts all gentle and protective—but he's a total beast when he wants to be."
Shin didn't deny it.
Instead, he gave the girls a slow, confident smile, his fingers brushing Ai's thigh just enough to make her shiver again.
"He does it all the time me," Ai continued, voice sing-song, "he fingered my ass until I scream his name."
"Ai!" Yuki squeaked, covering her mouth.
Aiko just stared. "You loved it."
Ai shrugged innocently. "Maybe."
Shin leaned forward, wrapping his arms around her from behind, lips brushing her ear.
"She twitches so much that I think she'll break."
Ai's entire body shivered, and she smacked his arm lightly. "See? See what I mean? Total pervert!"
The girls on screen moaned in unison.
Ai looked back at the camera, eyes gleaming with mischief.
"And you know what the worst part is?"
Aiko and Yuki leaned in.
"He doesn't even come."
They both froze.
Shin's smirk widened.
"He makes me come over and over again," Ai whispered, voice like silk, "and he still remains hard. Just waiting. Torturing me."
Shin growled softly in her ear. "I was enjoying the view."
Ai bit her lip.
Yuki whimpered. "You're gonna let him, right?"
"Eventually," Shin said. "But only after I make her beg."
That got a laugh out of all three of them.
Shin only tightened his grip on Ai, nuzzling against her shoulder.
"You're mine," he murmured. "And no amount of teasing will change that."
Ai purred in delight. "I know, Onii-chan."
And on the screen, two jealous, desperate girls could only watch as Ai basked in her perverted brother's warmth, smug and utterly satisfied.

The blanket rustled softly as Ai buried her flushed face into Shin's chest. Her hair, messy and wild from the night's chaos, stuck to her forehead as she pouted against him.
"You're so mean, Onii-chan," she murmured, voice muffled. "You always make fun of me after everything."
Shin chuckled lowly, brushing his fingers through her tangled hair. "Oh? I don't recall making fun of you. Just reminding you that you're the one who climbed into my bed, got all needy, and then acted all innocent."
Ai kicked at his shin under the blanket, her cheeks burning. "Stop teasing me…! I just—It was the perfect chance!"
He leaned close, whispering into her ear, "You mean because a certain someone finally rolled away in his sleep?"
She froze.
Shin's grin widened at the reaction. "Yup. Around two in the morning. That little monkey finally stopped clinging to me for once."
"Don't call Asahi a monkey," she muttered, still red. "Even if he is one."
Shin laughed, and Ai turned her face away with a loud "Hmph!"
"Speaking of," Shin said with a mischievous gleam in his eye, "What do you think would happen if he wakes up right now? What if he sits up, rubs his sleepy eyes, looks over here, and sees you like this?"
Ai gasped, grabbing the edge of the blanket and yanking it over her head. "Nooo! Don't say that! He'll never let me live it down! He'll cling to you more than ever, and—and he already thinks I'm a mean big sister!"
Shin smirked. "You kind of are. Always glaring at him like he stole your spot."
"He did steal my spot!"
"You had your chance. You just didn't act fast enough." He pinched her cheek under the blanket. "But now you did. Pretty bold of you, Ai…"
Ai peeked out from under the blanket and stuck her tongue out at him. "Because I love you more than anyone! I won't lose to that clingy brat!"
Just then, Aiko's voice rang out again from the phone, which had been set upright at the foot of the bed. "Umm… Should we be watching this? I feel like I should be covering Yuki's eyes."
"I'm seventeen, you know," Yuki muttered, half-buried in a pillow on her bed. "Not seven like your precious 'A-Chan'."
"A-Chan is adorable!" Aiko defended with a pout. "He's like a living doll! I'm gonna steal him and take him home with me one day."
"Please do," Ai mumbled from the blanket. "Maybe then I can finally have one full night of sleep next to Onii-Chan without a third wheel in the middle."
"Oh my," Aiko said with an exaggerated smirk. "Sounds like someone's got serious jealousy issues."
Shin smiled lazily, running a hand down Ai's back beneath the blanket. She let out a soft sigh at the touch, curling into his warmth. "Well," he said calmly, "If either of you two want to be this close to me like Ai…"
He paused. The teasing smile returned.
"…then come over. Right now."
"H-Huh?" Aiko blinked, clearly caught off guard.
Shin leaned toward the camera, voice low and smooth. "Skip school. I'm not stopping you. You were planning to come anyway. Might as well come faster."
Aiko narrowed her eyes. "Are you seriously trying to tempt both of us like that… while you're in bed with your sister?"
Ai peeked out again, grinning with flushed cheeks. "He's awful, right?"
Shin gave a little shrug. "What can I say? You three keep making it too easy."
"Pervert," all three of them muttered in unison.
Still smiling, Shin glanced toward the side of the bed where a tiny lump was curled up under another blanket. "Anyway," he whispered, "Before little Asahi decides to wake up and ruin everything…"
He reached forward and pressed the button to end the call.
The screen blinked off.
The room fell into a quiet, cozy warmth. Ai lay against his chest, listening to the soft rhythm of his heartbeat, the faint sound of Asahi's breathing just a few feet away.
"…You're really going to let them come, aren't you?" she asked sleepily.
"Only if they can keep up with you," he whispered, pressing a kiss to her forehead.
