The early spring night wasn't very hot, and the room felt slightly cool. Yet, Hoshino felt his body gradually growing warmer.
Haruno Sora shifted slightly, adjusting to a more comfortable position. Unlike before, she wasn't tangled around Hoshino as tightly, but her slender legs still rested on him, as if she were clinging to a large stuffed toy.
"Onii-chan," Haruno Sora called softly. Even with her changed position, she could feel something pressing against her lower abdomen.
Seeing her somewhat shy expression, Hoshino knew he couldn't hide it. He simply said, "Do you know the consequences of sleeping with a boy at night?"
"What consequences?" Haruno Sora, nestled in his arms, looked up at him with innocent, pitiful eyes like a little rabbit.
"The consequence is that I'll spank you," Hoshino said, patting her small, perky bottom. "You know you're not a little girl anymore, yet you insist on sneaking in."
As he spanked her, he felt as if he were patting a small rubber ball.
"No spanking! Onii-chan, you're shameless!" Haruno Sora buried her face in his chest, and he could feel the scorching warmth radiating from her skin.
"Then where should I spank you instead?" Hoshino nonchalantly withdrew his hand. Indeed, he could no longer spank her as freely as he once did—the feel of a young woman was different.
"You can't spank me anywhere!" Haruno Sora secretly lifted her pretty face. "Actually, Onii-chan, you know I'm not a little girl anymore. You're just trying to distract yourself."
"If you know, then don't cling so close," Hoshino said, finding it hard to avoid her gaze. His eyes fell on the strap of her nightgown, which had slipped down, revealing her fragrant, soft shoulder.
"I want to cling to you. Your little sister is your personal warmer," Haruno Sora said, hugging Hoshino as if撒娇. "It's been so long since we last slept together."
"Don't make it sound like we used to sleep together often. The only reason I slept with you before was because you said you were afraid of bugs and mosquitoes," Hoshino replied, now relying on conversation to divert his own attention. "Besides, the last time we slept together was years ago."
"Exactly because it's been so long, we need to maintain our bond," Haruno Sora said, as if it were the most natural thing in the world. "The only place your little sister can sleep is in your arms."
Hoshino didn't remember teaching Haruno Sora to be like this. Where did she learn such twisted logic? From those adult games?
"Alright, you should go to sleep now. I need to sleep too," Hoshino said, as if coaxing a child.
Haruno Sora stared at Hoshino, blinking, showing no intention of sleeping.
"What do you want?" Hoshino asked, somewhat helplessly.
"It's Onii-chan who won't let me sleep," Haruno Sora said with a hint of smugness, looking at him expectantly. "Do you want me to help?"
Hoshino's breathing grew heavier. He was not a man who could remain unmoved by such proximity. In the past, he could still see Haruno Sora as just his little sister, but after tasting her sweetness last time, his body no longer obeyed him.
The little girl from before had now learned how to tempt a man. Just lying in his arms with her flushed face and asking such a question was more potent than any experienced woman.
Soon, Hoshino snapped back to reality.
Haruno Sora had already quietly slipped her small hand downward. Once a man reveals his weakness, it's often easily seized by a girl.
"So impressive," Haruno Sora murmured, feeling a scorching heat that seemed to spread throughout her body. Her eyes sparkled with excitement.
"This isn't something fun to play with," Hoshino said, inhaling her fragrance. It was too alluring, making him unable to resist glancing at her chest. The strap of her nightgown had slipped further, revealing a small, snow-white mound.
"But it is fun! I think it's cute, and I really like it," Haruno Sora said with a mischievous smile. "Besides that, what are you looking at?"
Was it because she now held his weakness that her inner little devil was emerging?
Hoshino felt as though his little sister had turned into a mischievous child, stirring strange emotions within him.
What Haruno Sora wanted was simple: to make their relationship a fait accompli. That way, Izumi and Masana would have no choice but to back down.
As for a harem, Haruno Sora didn't believe for a second that Izumi would ever accept it. Just as she couldn't imagine herself sharing a bed with Izumi, she doubted Izumi could ever picture the two of them serving Hoshino together.
Though she was deeply embarrassed, Haruno Sora was determined to see this through. Hoshino's reaction was all the encouragement she needed.
The girl's small hand gently grasped Hoshino. Her slender, soft fingers coiled around him like a silent white serpent ensnaring its prey, poised to swallow it whole with a boneless softness that felt both dangerous and thrilling.
Just as Haruno Sora was focusing on her task, Hoshino suddenly pulled her closer, his hand resting on her shoulder before sliding downward.
Haruno Sora let out a soft "Ahn!" Her whole body trembled lightly a few times. She instinctively looked up at Hoshino and found him gazing down at her. Only then did she realize how close they were—close enough to feel each other's breath and hear the indistinguishable beating of their hearts. She bit her lip, her clear, bright eyes gradually clouding with a hazy mist, tinged with a hint of pink.
"Mi..." Haruno Sora no longer called him "Onii-chan." She squirmed slightly in his arms, her breathing growing increasingly rapid. The little rabbit had completely fallen into the hands of the rogue.
"It seems my Sora is becoming more and more mischievous. Should I punish her?" Hoshino whispered softly in her ear, causing her body to tremble once more.
"Mmm..." Haruno Sora panted, her body growing weak. She remembered now—Hoshino had always been particularly mean.
Whenever she acted like a spoiled, misbehaving child, Hoshino would spank her.
