Rias [R-18]

Algernon carries Rias into a lavishly decorated bedroom illuminated by the soft glow of moonlight streaming through large windows. The bed is adorned with crimson silk sheets, reflecting Rias' signature color, and the air is faintly scented with roses.

There's a blend of tenderness and tension in the air. The room is quiet except for the sound of their soft breaths, heightening the intimacy of the moment.

As, Algernon laid Rias on bed. He once again claimed her juicy lips.

After ending their kiss Algernon's lips curls into a smirk as he leaned on her ears biting her earlobes as he said "Rias. I am going to make you fell things you have never felt before. Are you ready?"

Rias's response was breathy whisper, her eyes half lidden with desire. "I have been ready for this. Now please, make me yours"

"Take off your shirt," He commanded, his voice low and authoritative. "I want to see all of you."

Rias's hand move swiftly, unbuttoning her shirt with practiced ease. With a final flick of her finger she shrugged the shirt off her shoulders and throwing it across the room leaving her upper body bare.

Algernon's eyes roamed over her bare chest, taking in sight of her ample breasts, the tip of her nipples hardened with arousal.

His hand moved to cup one of her breasts, his thumb brushed over her nipple, eliciting a soft moan from rias.

"You're so sensitive, Rias" he murmured, his tone both teasing and admiring. "I love that about you"

Rias bit her lip, her eyes fluttering closed as she savored the sensation of his touch. "Only for you, Darling~~," she whispered, her voice breathless with desire.

Algernon's lips found her neck, kissing a trail down to her collarbone before moving lower, his mouth capturing her other nipple. Rias gasped, her back arching as she pressed herself against him, her fingers tangling in his hair.

He continued his assault on her senses, his lips and tongue working in tandem as his hands explored her body. His fingers trailed down her sides, gripping her hips firmly before sliding under her skirt, his touch sending sparks of electricity coursing through her.

he hooked his fingers under the waistband of her panties and pulled them down, discarding them carelessly on the floor. Rias's skirt fluttered back into place, barely covering her now exposed Pussy.

Algernon's hands gripped her hips, lifting her slightly as he positioned himself between her legs. Rias's breath hitched in anticipation, her body trembling with the intensity of her desire. She felt the tip of his cock brush against her entrance, and a soft whimper escaped her lips.

"Are you ready, Rias?" Algernon asked, his voice low and filled with lust.

Rias's response was immediate, her voice trembling with a mix of excitement and longing. "Yes, Algernon... please, take me..."

Algernon didn't need any further encouragement. With a powerful thrust, he buried himself inside her tearing open the hymen, a deep groan of satisfaction rumbling in his chest as he felt her warmth envelop him.

Rias cried out, her nails digging into his shoulders as she clung to him, her body arching in response to the overwhelming sensation as red blood came out from the gaps of her pussy.

Algernon remained buried deep inside Rias, relishing the tight warmth that surrounded him. He could feel every trembling pulse of her body as she adjusted to the size of him, her breath coming in quick, shallow gasps. Rias's nails dug into his back, her hold on him fierce as she tried to steady herself.

After some time. With a slow, deliberate motion, he began to pull back, dragging his length out of her inch by inch, only to thrust forward again with a sudden, forceful push. Rias's head snapped back, a loud moan spilling from her lips as the pleasure hit her in waves.

Algernon's hands gripped her hips firmly, holding her in place as he set a steady, powerful rhythm. Each thrust was calculated, hitting just the right spot to make Rias cry out in pleasure, her voice echoing in the room. The sound of skin slapping against skin filled the air, accompanied by the wet, obscene noises of their bodies coming together.

Rias's legs wrapped around his waist, pulling him closer as if she couldn't bear even the slightest distance between them. Her hands tangled in his hair.

Algernon's gaze traveled over Rias's flushed face, her half-lidded eyes glazed with lust, her lips parted as she panted heavily. He was completely captivated by the sight of her, lost in the way her body responded to him, the way her voice trembled with every word.

He leaned down, capturing her lips in a fierce, hungry kiss, his tongue plunging into her mouth with the same intensity as his thrusts. Rias moaned into the kiss, her arms tightening around his neck as she kissed him back with equal fervor. Their tongues tangled together, the taste of each other only heightening the arousal that coursed through their bodies.

Rias's breath hitched, her entire body trembling as she teetered on the edge of release. "Darling~... I'm... I'm going to—"

Before she could finish, her orgasm crashed over her like a tidal wave, her entire body seizing up as she screamed his name. Her walls clenched tightly around his cock, milking him for everything he had as she rode out the waves of her climax.

The sight and sound of Rias coming undone beneath him was too much for Algernon. With a few final, powerful thrusts, he buried himself deep inside her and let out a low, guttural groan as he reached his own release. His cock pulsed inside her, releasing thick ropes of cum that filled her completely.

Rias moaned softly as she felt the warmth of his seed inside her, a shudder of satisfaction running through her body. She clung to him, her body trembling as she tried to catch her breath, her mind still reeling from the intensity of her orgasm.

For a few moments, the only sounds in the room were their heavy breathing and the faint rustle of the sheets as they lay entangled together. Algernon remained inside Rias, their bodies still joined as they basked in the afterglow of their lovemaking.

Algernon finally pulled out of her, his cock slipping free with a soft, wet noise. Rias sighed, a mix of contentment and longing in her voice as she felt the sudden emptiness inside her. But before she could dwell on it for long, Algernon was already shifting his focus, his hands gently caressing her body as he leaned down to kiss her again.

"You were amazing, Rias," Izashi murmured against her lips, his voice filled with affection. "So beautiful... so perfect..."

The warm rays of the morning sun filtered through the crimson drapes, painting the room in a soft golden glow. Algernon stirred, his body aching pleasantly from the intensity of the night before. The faint scent of roses lingered in the air, intertwined with the unmistakable fragrance of Rias.

His eyes fluttered open, and his gaze immediately fell upon her. Rias lay atop him, her bare form pressed against his, her crimson hair cascading over her shoulders like a waterfall of fire.

Her face was serene, a small, content smile playing on her lips even in sleep. They were tangled together beneath the silk blanket, the intimacy of their bond etched into every detail.

Algernon's mind raced as flashes of the night before played in his memory—Rias' whispered confessions, the heat of their touch, and the overwhelming connection that left them both vulnerable yet whole. He couldn't help but smile.

Just as he was lost in his thoughts, a familiar chime echoed in his mind—a sound only he could hear.

[The Harem Function has been unlocked]

[This function increases the training efficiency of bonded partners and grants rewards based on the strength of their connection.]

[First Bond Achieved!]

[Reward: Power of Destruction Trait (Inherited from Rias Gremory)]

Algernon's eyes widened as the notification unfolded in front of him, a glowing screen visible only to him. The words "Harem Function" caught his attention, but it was the reward that left him speechless.

"Power of Destruction…" he murmured under his breath, careful not to wake Rias.

He instinctively closed his eyes, feeling a rush of energy surge through him. It was as if a storm had been unleashed within his soul—a dark, pulsating energy that he knew was the hallmark of the Gremory bloodline.

Yet, this was different. It wasn't just borrowed—it was his, completely fused with his own powers.

Algernon sat up slightly, careful not to disturb Rias as she drifted back into peaceful sleep. The storm of energy within him continued to swirl, its intensity refusing to settle. His veins felt as though they carried molten power, each beat of his heart reverberating with destructive might. He clenched his fists, trying to ground himself, but the sensation only grew stronger.

Suddenly, the system's chime echoed in his mind again, louder this time, as if demanding his attention.

[Quest Completed: Conqueror the heart of Rias Gremory]

[Reward: Sub-Tier up in both magic and physical realm]

Before Algernon could even process the message, a brilliant light engulfed him. His surroundings faded—the warmth of Rias' presence, the softness of the bed, the crimson glow of the morning—all replaced by a void of endless white.

Algernon stumbled slightly as he found himself standing in a closed space, an endless expanse of blinding light that seemed to stretch infinitely in all directions. The air was unnervingly still, yet it crackled faintly with energy, a constant reminder of the system's omnipotent presence.

"What… where am I?" he muttered, his voice echoing eerily in the emptiness.

Before he could demand answers, the system's voice resonated, no longer a chime but a deep, commanding tone.

["This space is your reward for completing the quest, Host. Time in the outside world has stopped, allowing you to train and master the Power of Destruction without interference. You will not leave until you have ascended to the next sub-tier."]

Algernon's jaw tightened, his hands balling into fists. His crimson eyes burned with irritation as the weight of the words sank in.

"This is what you call a reward?" he snapped, his voice rising. "All I've done, and you couldn't just—what's the word—instill the power into me? Like in other novels? Systems just give their hosts what they've earned!"

He spread his arms wide, motioning to the endless void around him. "Instead, you throw me into this… this prison and expect me to train? What's the point of a system if it doesn't make my life easier?"

The air grew heavier, the crackling energy intensifying. For a moment, silence reigned, broken only by the sound of Algernon's frustrated breathing. Then, the system's voice returned, sharper and colder than before, like the blade of a guillotine.

["Are you done whining, Host?"]

Algernon froze, stunned by the system's tone.

["You dare to call yourself a future Supreme, yet you can't handle a simple challenge? You'd prefer I hand you power without effort? Then hear this: I do not need a weak, complacent host. If you cannot grow without being spoon-fed, you are no Supreme. You are trash. And if you are trash, you are not worth the system's time or energy. If I left, you'd crumble into obscurity."]

The words hit Algernon like a punch to the gut. For the first time, he felt the weight of the system's expectations. His irritation gave way to shame as he clenched his fists, his shoulders tense.

The system wasn't done.

["A true Supreme earns their power, piece by piece, through effort and resolve. Power without control is a double-edged sword, one that will destroy you and everyone you care about. You think your journey will be a series of easy victories? You are mistaken. If you cannot endure this trial, then leave—reject the system, and return to your mediocre existence."]

The words cut deep, extinguishing the spark of rebellion in Algernon's spirit. He stood in silence, his breathing steady but heavy. He wanted to argue, to demand an easier path, but the system's words gnawed at his pride.

Could he really call himself Supreme—if he crumbled at the first sign of hardship?

With a deep breath, Algernon straightened his posture. His crimson eyes, once clouded with frustration, now gleamed with determination.

"You're right," he admitted quietly, his voice steady. "I don't need to be handed power. I'll earn it. I'll master it. Not just for you, but for myself."

With that Algernon begin his training with his renewed resolve.
