He scooped her into his arms. She gasped softly, her face red but her eyes bright, filled with trust and affection. He carried her toward the bed, laying her down carefully as if she were the most delicate thing in the world.

"Onii-Chan…" she whispered, her voice trembling yet filled with longing. "I need you…"

Her outstretched hands reached for him, and he couldn't resist her. He climbed onto the bed, closing the distance between them as he pulled her into another kiss. This one was slower, deeper, our breaths mingling as our emotions poured into each movement.

Her lips parted, Inviting him in, and he kissed her more passionately, his hand gently cradling her face. She let out a soft, breathless moan against my lips. "I love you, Onii-Chan," she murmured, her voice barely above a whisper but filled with unwavering devotion.

He pulled back just enough to smirk at her, his voice teasing yet affectionate. "You're so cute."

Her cheeks flushed even deeper, but she nodded. "O-Onii-Chan…" she stammered, her voice dripping with both nervousness and desire. "Touch me… more."

He hesitated for the briefest moment, ensuring this was what she truly wanted, before sliding his hands gently down her sides, feeling the curve of her waist beneath his fingers. Her breath hitched, and she let out another soft moan, her hands clutching at me as if she needed me closer.

"I want you," she whispered, her eyes locked into his.

"I want you too," He replied, his voice trembling with anticipation.

As he gazed into her eyes, their lips locked in a passionate kiss. He couldn't help but feel drawn to her. His hands began to explore her curves, tracing the softness of her skin.

"Your body is incredible," He whispered, his eyes roaming over her. Her cheeks flushed, and her heart raced against his. His fingers danced against her breasts, feeling their firmness and softness. He gently cupped them, hid thumbs circling her nipples.

"You're so beautiful," He breathed.

Her hands slid under his shirt, feeling the definition of his abs. He shivered at her touch. As they continued to kiss and explore each other's bodies, their passion grew. His hands slid down to her waist, feeling the curve of her hips.

"Can I take this off?" He asked, his fingers on the hem of her pullover. She nodded, and he gently lifted it over her head. Her lacy black bra accentuated her cleavage, and his eyes widened in appreciation.

"Stunning," He whispered.

He unhooked her bra, and her breasts spilled out, round and firm. He started massaging them, feeling the softness of her skin. She moaned as he continued.

Her hands slid to his waistband, and she unbuttoned his jeans. As they undressed each other, anticipation built. Finally, they lay naked, their bodies aligned. He gazed at her, taking in her curves.

"You're perfect," He whispered.

She smiled, her eyes shining with desire. As he positioned himself at her entrance, his heart raced with anticipation. Their eyes locked, and he saw the desire burning within her.

"I want you so badly," He whispered, his voice husky.

Her hands wrapped around him, her nails digging into his skin. "I want you too," she replied, her voice barely audible.

With a gentle thrust, he entered her, feeling her warmth envelop him. Her eyes widened, and her lips parted in a silent gasp. His movements were slow and deliberate, savoring the sensation of being inside her. Her hands tightened around him, her body arching to meet his.

"You feel amazing," He whispered, his lips grazing her ear.

Her response was a soft moan, her body shuddering beneath mine.

His pace quickened, desire building within him. Minami's hands slid to his shoulders, her nails digging in deeper.

"Harder, Onii-Chan," she whispered, her voice urgent.

He obliged, his thrusts becoming more intense. Minami's body responded, her muscles tightening around him.

Their lips locked again, his tongue sliding in, their saliva mixing together.

Minami moaned, her hands wrapping around his head.

Their movements became frenzied, their bodies lost in the intensity of their desire.

Minami's legs wrapped around his waist, pulling him closer. "Do it... inside me," she whispered, her voice insistent.

He nodded, his body tensing as they came together.

They climaxed, their bodies shuddering in unison.

"Onii-Chan!" Minami cried.

In that instant, He felt their connection deepen, their love shining brighter than ever.

Minami lay curled up against Kazuya's chest, her small fingers tracing lazy patterns on his bare skin. The warmth of their bodies lingered, and the room was filled with the soft rhythm of their breathing.

Kazuya smirked, his hand lazily running through her hair. "You're so cute when you're shy," he murmured, feeling her stiffen slightly.

Minami let out a small whimper and buried her face deeper into his chest. "D-Don't say things like that," she mumbled, her voice muffled against his skin.

He chuckled, enjoying how flustered she got. "But it's true. You were really bold earlier, Minami," he teased, tapping his fingers lightly against her back. "Saying all those things… clinging to me so desperately."

Minami's entire body tensed, and she swatted his arm weakly. "S-Stop it!" Her voice was barely above a whisper, but the heat in her cheeks was unmistakable.

Kazuya laughed, pulling her closer. "What? I'm just appreciating the moment." He pressed a lazy kiss to her forehead. "You were adorable. And really, really eager."

Minami groaned in embarrassment, squeezing her eyes shut. "I-I wasn't that eager…"

Kazuya arched a brow. "Oh? So if I wanted to go for another round right now—"

She cut him off with a sharp squeak, her hands flying up to cover his mouth. "D-Don't say that!"

He licked her palm playfully, making her yelp and pull her hands back. His smirk widened. "See? So shy now, but earlier—"

Minami quickly turned her back to him, curling up into a ball. "I-I don't want to hear it anymore!"

Kazuya chuckled, slipping an arm around her waist and pulling her back against him. "Alright, alright, I'll stop teasing." He nuzzled into her hair, enjoying the scent of her.

They lay in comfortable silence for a while, the only sound being the occasional rustle of the sheets as Minami shifted slightly.

Then, after several minutes, she spoke in a tiny voice.

"Onii-Chan…"

"Hmm?"

She hesitated before continuing, her fingers gripping the sheets. "...Y-You did it inside."

Kazuya blinked, then smirked, immediately understanding what she was getting at. "Oh? And what exactly do you mean by 'it'?"

Minami stiffened. "Y-You know!"

He turned her around effortlessly, pinning her beneath him with a playful grin. "No, I don't. Why don't you say it properly?"

Minami's face turned scarlet, and she covered it with both hands. "I-I won't!"

Kazuya laughed, prying her hands away gently. "Come on, Minami. Just say it. I'll reward you."

She pouted up at him, her lips trembling. "Y-You… you finished inside…"

He let out a satisfied hum. "Mmm, yeah. I did." He leaned down, his lips brushing against her ear. "It felt amazing, too."

Minami whimpered, covering her face again. "Y-You're horrible!"

Kazuya laughed, pressing a kiss to her burning cheek. "And you love it."

Minami peeked at him through her fingers, her lips trembling before she murmured shyly, "…I do."

His expression softened at her honesty. He pulled her close, wrapping both arms around her. "Good. Because I love you too."

Minami sighed against his chest, letting the warmth of his embrace soothe her embarrassment. "Mmm… I love you, Onii-chan."

---

Minami fidgeted in Kazuya's arms, her small hands gripping the sheets as she pressed her forehead against his chest. Despite the warmth of their embrace, her thoughts swirled in a mix of emotions—embarrassment, nervousness, and the lingering echoes of pleasure.

Kazuya, ever the tease, tightened his hold around her waist and smirked. "You're still red, Minami. You were the one who begged for it, you know?"

Minami stiffened. "I-I didn't b-beg!" she stammered, her voice cracking.

"You totally did." Kazuya chuckled, his fingers tracing slow circles on her lower back. "You even pulled me in tighter at the end, remember?"

Minami's eyes widened, and she let out a frustrated groan before pushing against his chest. "S-Stop teasing me about it!"

He only grinned, letting her create some distance but still keeping an arm draped around her. "Alright, alright, I'll stop… for now."

She sat up slightly, pulling the sheets around her bare shoulders as she bit her lip, clearly thinking about something. Her brows furrowed slightly, her fingers clenching the fabric as she took a deep breath.

"Onii-Chan…"

"Hmm?" He propped himself up on one elbow, watching her with curiosity.

Minami hesitated, then looked at him seriously. "We… need to talk about what happened."

His smirk faded slightly, recognizing the shift in her tone. He nodded, sitting up a bit as well. "Alright. What's on your mind?"

She swallowed, her fingers playing with the edge of the sheet. "I… I asked you to do it inside," she admitted, her cheeks burning. "I really wanted it. I still do. But…" She glanced at him, her expression conflicted. "You know what that means, right?"

Kazuya blinked, then exhaled softly. "Yeah… I do."

Minami lowered her gaze, fidgeting. "I-If I get pregnant… my life will change. Our life will change." She clenched the sheets. "I'm not saying it's your fault! I asked for it. I wanted it. But still… I just… I think we should talk about it properly."

Kazuya studied her for a moment before nodding. He reached out, cupping her cheek gently. "You're right. We should."

Minami leaned into his touch, closing her eyes for a second before sighing. "I… I don't regret it," she admitted softly. "But I also didn't think about everything at that moment."

Kazuya tilted his head. "Do you regret it now?"

Her eyes snapped open, and she shook her head quickly. "No! That's not what I mean!" She bit her lip. "I just… I don't know how to feel. It makes me happy that we're connected like this, but at the same time, I'm scared."

Kazuya's expression softened. He pulled her into his arms again, holding her close. "It's okay to feel that way, Minami."

She relaxed against him, her fingers gripping his arm. "I-I mean, I'm almost sixteen… but I don't think I'm ready to be a mother yet," she whispered.

Kazuya pressed a kiss to the top of her head. "You won't have to go through anything alone. No matter what happens, I'm here for you."

Minami sighed. "I know."

He smirked slightly. "Still… you were really desperate earlier."

She immediately tensed and punched his arm weakly. "Onii-Chan!"

He laughed, dodging another halfhearted slap. "What? I'm just saying!"

"You're ruining the serious talk!" she huffed, glaring at him.

Kazuya tightened his hold around Minami, feeling the warmth of her bare skin against his. The soft rise and fall of her breath, the way her fingers clung to his arm—it all told him how vulnerable she felt in this moment. He knew her well enough to understand that even though she had been the one to ask for it, the weight of reality was now settling in.

He gently tucked a strand of her hair behind her ear, his voice low and steady. "Minami… if you do get pregnant, I'll take responsibility. Completely."

Minami tensed slightly, but she didn't pull away. Instead, she pressed herself closer to him, as if searching for reassurance. "You mean that…?" she whispered, almost afraid to hear the answer.

Kazuya placed a firm kiss on her forehead. "Of course I do. If we created a life together… it wouldn't just be your child. It would be ours. Our baby."

Minami sucked in a sharp breath, her fingers gripping his arm tighter. "O-Ours…" She repeated the word softly, as if testing how it felt on her lips.

He cupped her cheek, making her look at him. "I'd be there for you every step of the way. No matter what. You wouldn't have to go through it alone."

Her lower lip trembled, her eyes shining with emotion. "But… what about your career? What about your future?"

Kazuya smirked slightly, rubbing small circles on her back. "What about yours? You think I'd ever let you carry all that responsibility alone?" His expression softened. "We'll figure it out. Together. If it happens, we'll do everything we can to give our child the best life possible."

Minami swallowed hard, burying her face in his chest. "You're making me cry, idiot…" she muttered, her voice muffled.

He chuckled, kissing the top of her head. "Then cry. I'll hold you as long as you need."

She sniffled against him, her body relaxing little by little as his words sank in. "You really mean it, don't you?"

"Of course I do." His arms tightened around her. "Minami, I love you. I'd love our child too. If you ever got pregnant, that baby would be just as much mine as yours. And I wouldn't run away from that."

Minami trembled slightly, then let out a soft, breathy laugh. "You say that so easily… like it's not scary at all."

Kazuya smiled. "It is scary. But if it's with you, then I know we can handle anything."

She pulled back just enough to look into his eyes, her own filled with warmth and something deeper—trust. "You really are amazing, Onii-Chan…"

He smirked. "I know."

Minami huffed, smacking his chest lightly. "Ugh, I was being serious, idiot!"

He laughed, grabbing her hand and pressing a kiss to her fingertips. "And I was being serious too, Minami. You don't have to be afraid. No matter what happens, I'm with you."

She exhaled slowly, then snuggled back into him, her fingers tracing small patterns on his skin. "I… I think I needed to hear that," she admitted softly.

Kazuya kissed the top of her head again. "Then I'll say it as many times as you need."

She let out another breath, this time steadier. "Our child…" she murmured, as if the idea was finally settling into her heart. "If it happens… we'll raise them together."

Kazuya smiled, resting his chin on top of her head. "Yeah. Together."

Minami pressed even closer, finally allowing herself to relax in his embrace. And as they lay there, wrapped in each other's warmth, she knew—no matter what the future held, she wouldn't be facing it alone.
