۞ Chapter 43.5 ⟴ The Big Yukinoshita Sister ۞ {+18}

The moon's enchanting glow faded as Haruno and Daiki's attention turned to matters more pressing.

With him seated on the floor and her straddling his lap, their bodies drew closer as their tongues intertwined in a passionate dance. Their lips met and parted in a hypnotic rhythm, like lovers reuniting after an eternal separation. Heat bloomed between them with each passing second, their breaths mingling as they lost themselves in deep intimacy.

Yet this intimacy was new to Haruno, their swift progression driven only by urgent necessity. With the Matsushita Group's threat looming, she faced a stark choice between submission or death.

Daiki remained composed, simply appreciating the innocent woman's attempts to please him. After all, he was the one who needed to be satisfied in this arrangement.

As passion intensified, clothing fell away piece by piece during their intimate exchange, until nothing remained between them.

Haruno's ample bosom, more generous than Nino's, drew Daiki's admiring gaze, filling her with pride. Yet she was also flushed with embarrassment, her eyes darting between his face, his sculpted torso, and his impressive manhood.

"D-do you like them?" She asked, cradling her chest with her arms, trying to break the night's silence and mask her nervousness.

Daiki held her gaze for a moment, a slow smile spreading across his lips. Without a word, he let his actions answer, leaning forward deliberately to bury his face in her soft décolletage.

"Hmm~... Ahh~" Haruno bit her lower lip and arched her back as his hot tongue traced her sensitive peaks, sending shivers coursing through her body.

Their naked bodies drew closer with each passing moment. She shivered as his masculine form brushed against her untouched intimacy, each contact sending waves of new sensations down her spine.

Summoning her courage through her shyness, she reached out with trembling fingers. Her delicate hand found him, initiating tentative exploratory movements. In her innocence and inexperience, she gripped him more firmly than intended — yet this unconscious pressure only heightened their shared pleasure, making the moment of discovery even more profound.

And the inevitable approached.

Breaking from their passionate kiss, Daiki yielded to her gentle, inexperienced guidance. Haruno met his gaze briefly before closing her eyes, steeling herself for what was to come.

As their bodies joined in a slow, deliberate rhythm, thoughts flooded her mind: her innocence slipping away in this irreversible moment, the sacrifices made for her family, the harsh necessities of survival in this ruthless world — all these thoughts swirled like shadows in her consciousness.

"I wouldn't think about those things if I were you."

His soft whisper startled her eyes open, her pupils widening in surprise. His strong arms held her with tender firmness as their bodies moved as one in their intimate dance. His warmth enveloped her like a protective blanket, filling her with both security and desire. For the first time since this began, her heart beat to a different rhythm — no longer just fear or resignation, but an unfamiliar emotion that made her chest flutter with unknown intensity.

"You are mine now, understood?"

Before she could respond, pain overwhelmed her senses.

"Daiki, no—" Haruno gasped, her body trembling as she tried to escape from under the covers.

Her alabaster skin glistened with perspiration in the moonlit darkness. A delicate flush painted her features, evidence of their passionate encounter, while her chest rose and fell with each rapid breath. Her body, still quivering from exertion, seemed to glow with an ethereal beauty in the dim light.

She wasn't escaping because it was unpleasant — quite the opposite. It was too intense for her to handle!

His stamina had proven relentless over the past hour, maintaining a powerful rhythm that left her breathless. Each movement sent waves of sensation through her body, building in intensity with each passing moment. The raw power of his thrusts made her gasp for air, her body trembling under their intimate connection.

As he pulled her back beneath the covers, she felt his full force again. Her protests were silenced by his passionate kiss, and she could only surrender.

Daiki cast aside the sweat-dampened covers, exposing their intertwined forms in the dim light. Their bodies moved in perfect synchronization, slick with passion. Haruno's fingers interlocked behind his neck in a desperate grip, her legs parted in complete surrender as she yielded to their union.

His hips moved with steady rhythm, each motion driving deeper into her welcoming depths. The beautiful young woman beneath him couldn't contain her pleasure — muffled moans of ecstasy escaped her lips with each powerful thrust, her body responding to the overwhelming sensations.

Finally, after their intense session, he decided it was enough. Though Haruno seemed lost in pleasure, Daiki knew this was simply due to his expertise.

Her heart would need time to fully accept this, and then everything would be better.

His movements quickened, and Haruno sensed what was coming.

"Daiki, not inside—"

But before she could push him away, she felt a new warmth flood into her as he released. A novel sensation emerged that seemed to caress her very soul, triggering another climax.

Some time later, as they both caught their breath, Daiki withdrew, causing a pearlescent stream to flow from her.

"Daiki, why did you..." Coming down from her pleasure-induced haze, Haruno reached between her legs, feeling the warmth still flowing. The intense heat inside indicated there was far more within than without, "I—"

"Don't worry, you won't get pregnant that easily." Daiki interrupted, anticipating her concern, "I'm very strong, so my swimmers are too."

"Uh..." Haruno froze momentarily before understanding dawned, her cheeks flushing crimson. Internally, she breathed a sigh of relief, 'Thank goodness. Though it would be an effective way to bind him to the family, I'm not ready for children.'

"Still, you should clean up thoroughly. You're not looking to become a mommy yet, are you?" Daiki teased, knowing exactly what was running through her mind.

"Hmph! Next time, don't do that!" She pouted, trying to mask her thoughts with feigned indignation.

"So there will be a next time?"

Silence fell over the room as Haruno's face grew increasingly red. She had expected to be the dominant older sister in this situation but found herself reduced to a helpless girl before him.

"I-I'm going now." Aware of the pressing need to clean up, she attempted to stand.

The attempt proved futile... Her legs had turned to jelly, and every movement sent aftershocks of pleasure through her, causing more of their shared essence to spill.

"Aren't you forgetting something?" Daiki called out.

"Forgetting what?" Haruno asked innocently.

Seeing him gesture toward his impressive member, still glistening with their combined fluids, understanding dawned on her face.

'Hmph, you naughty boy! I'll make you pay for this!' Even with these thoughts, her body moved on its own towards him.

With graceful movements reminiscent of a curious kitten, she slowly crawled across the sheets toward him, her delicate form moving with feline elegance. After settling into position, she hesitantly extended her pink tongue.
