Sirin and Kiana Kaslana

Automatic door swished open...

But no one was there.

Puzzled, Shirou rubbed his eyes, blinking the sleep away. He climbed off the bed and began to over to the door, but the floor beneath him vanished. The sudden sensation of weightlessness took him by surprise, and he found himself falling through a swirl of colours.

In the blink of an eye, the room was replaced by a vast, desolate landscape. His bare feet met the cold, dusty surface of the moon. Being able to still breath didn't surprised him.

A blue and white marble suspended in the inky void.

He had an idea who might be responsible for this sudden and disorienting teleportation.

His eyes searched lunar landscape.

There she was. A girl with white hair tied in a ponytail, perched atop a large rock. Her golden eyes gleamed in the stark lunar light, reflecting the distant Earth.

"Kian... Sirin," He corrected himself.

The girl looked down, a knowing smile playing on her lips as she hopped off the rock. "Shirou Emiya," she greeted.

"How shall this mortal serve the Herrscher of Finalist?" Shirou asked, his voice carrying a hint of sarcasm as he straightened his posture.

His relationship with Kiana 'Sirin' Kaslana was complicated, to say the least.

Sirin an enemy turned lover, complications didn't come from that, no, but from the fact she was an alternate personality of Kiana Kaslana.

While Sirin might have turned into one of his lower, his relationship with Kiana was still that of a friend.

Although Kiana had agreed to let Sirin borrow her body, It was still bit awkward.

Sirin, with a playful glint in her eyes, sailed closer to Shirou, her movements as graceful as a moonlit ballet dancer.

"You know very well what I want, Emiya," she said, her voice echoing slightly in the vacuum.

Shirou couldn't help but smirk at her directness. "And what might that be?" He challenged.

Sirin's smile grew wider, and she stepped closer, closing the gap between them. Her eyes held a fierce determination that matched the gravity of the moon beneath them. "I want to feel you," she whispered, "in me."

With a swift move that defied the weightlessness, Shirou pressed her against the lunar surface, his hands firmly on her shoulders. The dust plumed around them, giving a momentary illusion of gravity. Her eyes widened in surprise, then lit with desire as she realized his intention.

"Here?" she whispered, a mix of challenge and anticipation in her voice. "You dare to claim me like I'm a whore?"

Shirou leaned in closer, his eyes locked onto hers. "You might not be whore, Sirin," he murmured, "But you are mine to claim and use." He didn't wait for a response, instead, his mouth found hers in a hungry kiss that conveyed all the passion and desire he had been holding back.

The moon's gravity seemed to increase as he pushed her down onto the dusty lunar surface, his body hovering just above hers.

Their kiss grew more intense as his hands roamed her body, stripping away the layers of clothing that separated them. The fabric of their clothes fluttered away into the vacuum of space, leaving them bare against the cold moon dust. Shirou's body heat was the only warmth she felt, a stark contrast to the chilling embrace of the moon.

Sirin wrapped her legs around him, drawing him closer. They kissed deeper, their breaths mingling in the vacuum. His hand found its way to her neck, gently caressing the soft skin before moving lower to cup her breast. Her nipples hardened under his touch, and she gasped into his mouth.

With a swift motion, He positioned himself between her legs, the cold dust a stark contrast to their heated bodies. He stared into her golden eyes, filled with hunger and need.

Sirin's heart raced as she felt his manhood press against her, the heat of his desire burning through the cold lunar dust. She reached down, guiding him inside her. The sensation was overwhelming, a blend of the alien and the intimately familiar.

Shirou groaned, the tightness of her embrace around his length sending shivers down his spine. He pushed in further, claiming her in the most primal way possible under the silent, unblinking gaze of the Earth above.

Sirin arched her back, her nails digging into the lunar dust as she moaned. The gravity of the moon was a mere trifle compared to the weight of their desire pressing down on them.

He watched her face, memorizing every twitch of pleasure and every gasp that slipped from her lips. The vacuum of space did little to muffle their sounds, making their intimate whispers echo in the vast emptiness.

With each thrust, Shirou felt Sirin's body tighten around him, her nails digging deeper into the moon's dust. He could see the stars reflected in her eyes as they glazed in ecstasy. Her breaths grew shorter, and her moans grew louder.

Her legs clamped around him, pulling him in deeper, urging him on. He increased his pace, driving into her with a fervor that seemed to match the heartbeat of the universe itself. The dust kicked up around them, a cosmic dance of passion and need.

Sirin's eyes rolled back in her head as she reached climax, her body convulsing with pleasure. The sensation was so intense it was almost painful, but she craved more. She tightened her legs around him, her nails leaving burrowing in the dust as she clung to the only source of warmth in the cold, lifeless expanse.

Shirou's own desire was a raging storm, each stroke a thunderclap that reverberated through the vacuum. He could feel her walls pulsing around him, her body begging for release. With one final, powerful thrust, he claimed her fully, his seeds spilling into the womb as she cried out in pleasure.

Her tongue out like a bitch in heat, Sirin kissed him back with a passion that seemed to light the moon itself.

His hips continued to move, driven by an insatiable need that seemed to grow with each passing moment. Sirin's body quivered beneath him, her moans echoing in the vacuum as she rode wave after wave of pleasure. Each thrust was a declaration of ownership, a physical assertion of his dominance over the moonlit goddess beneath him.

Her orgasms crashed over her like meteor showers, each one more brilliant than the last. Her eyes, wide with ecstasy, never left his as he claimed her over and over again.

And then, she went limp. He was more than she could take, but she had invited him to indulge. The gravity of their passion had overwhelmed her, and she lay beneath him, a panting, trembling mess.

Shirou didn't stop, his movements driven by a primal need, in his lust he didn't notice the shift.

Golden eyes turned clear blue again, and the smirk on Sirin's lips transformed into a tired smile as Kiana took back control of her body.

"Shirou, stop," Kiana's voice, weak but firm, broke through the haze of passion.

Shirou's eyes snapped open, realizing that it was Kiana looking back at him now, not Sirin. He immediately tried to pull out, but her legs held him in place, refusing to let go. Her grip was surprisingly strong, considering her exhausted state.

Shirou's mind raced, torn between his passion for the siren that was Sirin and the friendship he had sworn to Kiana. "I'm sorry, I didn't notice," he murmured.

"I should be angry," Kiana murmured, her eyes still smiling despite her words. "You have help me and my friend so much, Shirou."

"But, you also stole Mei-senpai from me," Kiana added, the mirth in her voice fading as she grew more serious. "if that wasn't enough, you had to claim my body too."

Shirou froze, his hands hovering over Kiana's body as guilt washed over him. "I'm sorry, Kiana," he said, his voice heavy with regret. "I didn't mean to..."

"Shirou, Do you know how much my body craves for you?" Kiana's voice was a whisper, sending shivers down his spine. "I spend half the day imagining the taste of something sticky and salty on lips, other half imaginary some hard and warm inside me."

Shirou swallowed hard, his body still pulsing with desire. "Kiana..."

"I don't even like men, Shirou but with you..." Kiana's voice trailed off, a hint of vulnerability in her eyes. Shirou felt a twinge of confusion, his mind reeling from the sudden revelation.

He looked into those blue eyes, the same ones that had seen so much, felt so much, and yet they remained clear and pure. "Are you sure?" He managed to ask.

"Go ahead, make me yours," Kiana whispered, her voice a soft caress against his ears.

Without another word, Shirou claimed her mouth once more, his kisses fierce and demanding. He wanted to consume her, to be the only thing she craved. His hands explored her body with a newfound urgency, memorizing every curve and contour as if he was afraid she might slip away again.

Kiana's body responded to his touch, arching up to meet him, her legs tightened around his waist to draw him in deeper.

Shirou lost himself in her, his mind a whirlwind of sensation and emotion. He kissed her neck, her collarbone, her breasts, leaving a trail of fire in his wake. Her breaths grew ragged, her moans grew louder, and with each touch, he felt her walls tighten around him.

During his journey he had received the blessings of many Goddesses. Goddesses that held the authority of love, lust, beauty, motherhood, fertility, maidenhood, purity, and more. He usually don't call upon them, but now was the time.

Within a moment of his decision, his body grew hotter, his strength amplified, desires amplified.

He pound into her, each thrust a declaration of his unbridled lust and need. Her cries filled the vacuum, a symphony of pleasure that resonated through her very soul. Her nails dug into his back, leaving trails of pain that only served to fuel his passion.

He could feel her walls contracting around him, tightening with each pulse of desire. He knew she was close, so close, and the thought sent a thrill through him that was almost too much to bear.

Shirou's strokes grew more erratic, driven by the fiery need to claim her completely. He didn't just want to be the one she craved in this moment; he wanted to be the only one she ever thought about, the only one she ever need.

Her moans grew more ****, her body shuddering with every thrust. She was close, so close to the edge, but he wasn't going to let her fall just yet. He slowed down, his movements deliberate, teasing, making her beg for it.

"Shirou, please," she whispered, her voice trembling with need.

Shirou smirked, his eyes filled with determination. He knew exactly what she needed, what she craved. He began to move again, his thrusts slow and deep, drawing out every ounce of pleasure from her quivering body.

Kiana's eyes wet with desire, she looked up at Shirou with a mix of need and submission. He could see the hunger in her gaze, the desperation to be filled by him, to be made complete by his touch. It was intoxicating, and he felt his resolve to hold back slipping away.

With a growl, he began to move again, his hips driving into hers with a **** that sent shockwaves of pleasure through her body. She clung to him, her legs tightening around his waist as if she could somehow pull him closer, deeper.

Then all hell broke loose, she came like a supernova, her body spasming around him, her nails digging into his skin as she screamed his name.

Shirou didn't stop, his body driven by a need to claim her completely. He could feel her orgasm rippling through her, her muscles clenching around him like a vice, trying to make him spill his seed.

But he held on, his control tightening like a noose around his own desires. He wanted more than just to satisfy her; he wanted to brand her soul with his very essence.

He picked up the pace, his movements becoming a blur of passion against the stark backdrop of the moon. The dust kicked up by their bodies created a veil that shielded their intimate dance from the prying eyes of the universe.

Pitch of her screams grew, echoing through the lifeless moon, Each of her orgasm was a declaration of her submission, her body begging for more. Shirou, fueled by the divine power he had been granted, gave it to her. He didn't stop, didn't let her rest, didn't allow the intensity to wane.

Orgasm after orgasm washed over Kiana, each more intense than the last. He knew that this wasn't just about sex, it was about something deeper, something primal. He had to fuck her until she craved only him, until the very fabric of her being was rewoven with his desires.

"Tell me Kiana, do you want taste of my seeds on your tongue or do you want me bury it deep inside your womb?" Shirou murmured against her ear, his hot breath sending shivers down her spine.

Kiana's eyes widened with shock at the explicitness of his words, but she didn't push him away. Instead, she bit her lower lip and nodded, her voice a mere whimper. "I...I want...in me,"

"Are you sure, usually I can control it but in my current state, I might get you pregnant," Shirou said, his voice thick with lust as he hovered above her, his eyes locked onto hers.

Kiana nodded, her breaths ragged and ****. "I need you inside me," she whispered. "I need to feel you fill me completely."

Shirou growled in response, his body moving with a feral intensity that was almost scary. The stars above them blurred as he claimed her over and over again, his thrusts punctuated by her cries of pleasure.

He felt himself reaching the edge, the pressure building up inside him like a volcano about to erupt. Kiana's body was a warm, welcoming haven, and he knew that the moment he let go, she would be forever changed.

With a final, powerful thrust, Shirou released his seed deep within her. It was like nothing he had ever felt before, a primal roar of satisfaction that seemed to shake the very foundations of the moon. His hot cum filled her, spilling into her womb as she writhed beneath him, her body still caught in the throes of pleasure.

Her eyes rolled back in her head, and she let out a long, low moan that seemed to carry across the lifeless landscape. The warmth of his release spread through her, filling her with a sense of completeness that was as profound as it was unexpected.

Kiana was spent, tiredness dragged her eyes but she couldn’t help but smile at the thought of his cum inside her. It was warm and comforting.

But she felt a sudden jerk and realized Shirou had yet to withdraw, his cock still buried deep within her.

"Again," he whispered, his voice hoarse with desire.

Before Kiana could even process his words, Shirou's hips began to move once more, his cock still hard and thick inside her. Her eyes shot open in surprise, staring up at him in disbelief.

"I can't take more," Kiana gasped, her voice barely audible amidst her panting breaths.

"Sorry, Kiana but it seems I've only just begun," Shirou murmured, a wicked smile playing on his lips as he pulled almost all the way out before sliding back in with a swift thrust that made Kiana's eyes roll back in pleasure.
