Illyasviel, Miyu & Chloe.

Shirou Emiya woke up with a sense of warmth and comfort, as if he were floating in a cloud of pure bliss. His eyes fluttered open, and he found himself greeted by a sight that was both shocking and incredibly erotic. Illyasviel von Einzbern, his beloved sister, was straddling him, her naked body glistening with sweat. Her long, silver hair cascaded down her back, framing her face as she looked down at him with a mischievous smile. He was inside her, his cock buried deep in her warm, wet pussy.

"Good morning, big brother," she purred, her voice a sultry whisper. "I thought I'd wake you up in a special way."

Shirou's mind raced, trying to process the surreal situation. He could feel her heat enveloping him, her movements sending waves of pleasure through his body. He reached up, his hands cupping her breasts, his thumbs circling her nipples. She moaned softly, her head falling back as she continued to ride him.

As his vision cleared, he noticed that they were not alone in the room. To his left, Miyu Emiya, was sitting on the edge of the bed, her eyes filled with desire as she watched them. She was naked, her body ready and eager. To his right, Chloe von Einzbern, illya's twin, was also present, her red eyes gleaming with anticipation. She too was naked, her body a vision of curves and softness.

Miyu Emiya, watched with her eyes filled with longing. Her hand slipped down her body, her fingers playing with her clit, her breathing growing heavier as she watched the intimate scene unfold before her. Her cheeks were flushed, and her chest rose and fell with each breath she took.

Chloe, unable to hold back any longer, leaned in and began to kiss Shirou's neck, her teeth gently grazing his skin. She whispered in his ear, "Cum quickly, Onii- chan. I want my turn."

He looked from Illyasviel to Miyu, then to Chloe. Each of them wore expressions of love and desire, their bodies ready for him. He felt a surge of lust and love, a mix of emotions that left him breathless. With a roar, he climaxed deep inside Illyasviel. Her body tightened around him, her own orgasm triggered by his release. She collapsed onto his chest, her breaths coming in ragged gasps.

Miyu didn't waste a moment. She pushed Illya aside, He groaned at the sudden loss of heat, but Miyu was quick to replace it. She straddled him, her wet pussy sliding down onto his still-hard but fluid covered cock. She began to ride him with a passion that matched the intensity of her emotions. Her eyes closed as she leaned into it, her head thrown back in ecstasy.

"Oh," she moaned, her voice a sweet symphony of pleasure. "Your cock feels so good inside me."

Illyasviel, not wanting to be left out, moved behind Miyu. Her hands roamed over Miyu's body, her fingers finding her sister's nipples. Miyu gasped, her movements becoming more urgent as Illyasviel teased and pleasured her.

Shirou's eyes wandered to Chloe, who had moved closer, watching them intently. Her hand slipped between her legs, her fingers working her clit as she watched. Her cheeks were flushed, and her breathing was labored. He felt a new wave of arousal wash over him as he took in the sight of her masturbating.

"Chloe," he murmured, reaching out to her. "Get ready, it's your turn next."

The words seemed to spark something in Chloe. She stopped her ministrations, a look of hunger.

Miyu, sensing the change in the air, turned to look at Chloe. "You're next," she said, her voice thick with desire. "But first, I want to feel him cum in me too."

Shirou felt a thrill at her words. He gripped Miya's hips tightly, his thrusts growing more powerful as he felt himself nearing the edge again.

Miyu's eyes snapped open, meeting his gaze with a fiery intensity. "Cum in me, brother," she begged, her voice a needy whine. "I want to feel you fill me up."

Her words sent a shockwave of pleasure through Shirou, and he knew he couldn't hold on much longer. He could feel Miyu's pussy clenching around him, her muscles tightening as she approached her own climax. He thrust into her harder, faster, their bodies moving together in perfect harmony.

"I'm going to cum," he grunted, his voice strained with passion.

Miyu's eyes widened, her movements becoming frantic. "Yes, yes," she whispered, her breath hot against his ear. "Cum in me, Onii-san. I want it all."

With one final, powerful thrust, Shirou released, his cock spasming as he filled Miyu with his seed. She cried out, her body trembling as she came with him, her pussy clenching down on him in waves of ecstasy. They remained locked in that intimate embrace for a moment, their hearts beating as one.

As Miyu slid off him, panting and satisfied, Chloe was already positioning herself, eager for her turn. Her eyes gleamed with hunger, and she licked her lips, her gaze never leaving Shirou's face. He watched as she straddled him, her soft, plump breasts bouncing slightly as she lowered herself onto his still-throbbing cock.

Shirou felt his cock stretch and fill her, her pussy tight and warm around him. She leaned forward, her hands on his chest, her breaths coming in short, sharp gasps.

Her breasts brushed against his chest with each movement, her nipples erect and begging for attention. He reached up, his hands cupping them, his thumbs flicking over the sensitive peaks. Chloe threw her head back, her moans growing louder as he touched her.

Miyu and Illyasviel watched the intimate scene with hungry eyes, their own desire growing with each passing moment. The sight of Shirou's cock disappearing into Chloe's pussy was too much for them to bear. Without a word, they turned to each other, their mouths colliding in a passionate kiss.

Their tongues danced together, exploring and tasting, as their hands roamed over each other's bodies. They broke the kiss, panting, and Miyu pushed Illyasviel onto the bed, her eyes never leaving her sister's. They were both soaking wet, their pussies begging for attention.

They locked their legs around each other, their bodies moving in a synchronized dance of passion. Miyu's tongue traced a path down Illyasviel's neck, her teeth grazing the sensitive flesh, making her shiver. Illyasviel's hands found Miyu's hips, her fingers digging into the soft skin as she pulled her closer, needing more of her touch.

Their moans filled the room, mixing with the sound of Chloe's increasingly urgent cries of pleasure. Shirou watched them, his cock still buried in Chloe's warmth, as he felt himself growing hard once more. The sight of his sisters entangled in such an intimate embrace was almost too much to handle.

Chloe began to pick up the pace, her hips moving in a rapid, rhythmic motion. He could feel her walls tightening around him, her breathing becoming erratic.

"Onii-chan," she moaned, her voice a sweet agony. "Fuck me harder, I want to cum."

Her words were like gasoline on a fire, igniting a new surge of lust within him. He gripped her hips and thrust up into her, their bodies moving in a frantic dance of passion. Chloe's breasts bounced with each movement, and he leaned up to capture one of her nipples in his mouth, sucking hard. She arched her back, her moan vibrating through his body.

Illyasviel and Miyu's kisses grew more heated as they watched Chloe ride their brother. Their hands were everywhere, exploring and teasing each other's bodies. Miyu's hand slipped between Illyasviel's legs, her fingers sliding into her wet pussy. Illyasviel's repaid the favor, her hand finding Miyu's clit and rubbing it in slow circles.

Chloe's breath grew ragged as she moved faster, her eyes locked on Shirou's. "I'm going to cum," she whimpered, her voice filled with need. "Cum with me, Onii-chan."

Shirou felt the pressure building, his cock pulsing within Chloe's tight embrace. He couldn't hold back anymore. He thrust deep into her one last time, feeling her pussy contract around him as she climaxed. The sensation was overwhelming, and with a roar, he released his load, filling her to the brim.

Chloe's body convulsed in pleasure, her eyes squeezed shut, her mouth open in a silent scream. Her nails dug into his chest, leaving little half-moons of red as she rode out the waves of her climax. Shirou felt his own release, his cock pulsing with each spurt of cum.

"Oh, Onii-chan," she whispered, her voice a hoarse whisper. "That was..." Her words trailed off, lost in the aftershocks of pleasure. She collapsed onto him, her breathing ragged and uneven. He could feel her heart racing against his chest.

Shirou's own heart was pounding in his ears, the sound a muffled roar that matched the throb of his cock, still buried inside Chloe. He looked down at her, her cheeks flushed and her eyes glazed over with satisfaction.

But before he could even consider climbing off the bed to start the day, a soft hand on his shoulder stopped him. He turned to find Miyu looking at him with a gentle smile, her own desire not yet sated. "Don't go anywhere, big brother," she murmured, her voice a sweet melody that sent shivers down his spine. "We're not done yet."

Illyasviel's hand joined Miyu's on his shoulder, her fingers interlacing with her sister's. "We want to make sure you're properly taken care of," she said, her eyes gleaming with mischief. "We can't let you leave unsatisfied."

With that, all three sisters lined up on bed, their bodies facing away from him. All three were on all four.

Miyu on left, illya in the middle and Chloe on right, all three of them positioned themselves like that, their backs to Shirou, presenting him with a visual feast that was both tantalizing and overwhelming. Each of their asses was a perfect handful, round and firm, with their pussies glistening below. He could see the evidence of their previous encounters, a slick trail of cum connecting their thighs, a testament to the passion that had been shared.

Shirou took a moment to appreciate the view, his cock already standing at attention once again. He leaned forward, placing a gentle kiss on Illyasviel's lower back before moving closer to her. He reached out, his hand sliding down her spine until he reached her plump ass. He could feel her tense in anticipation as he spread her cheeks apart.

Miyu and Chloe watched with bated breath, their own desires reflected in their eyes. He took a deep breath, then pressed the tip of his cock against Illyasviel's tight anus, feeling the heat and resistance. She gasped as he began to push in, her body stretching to accommodate his girth.

"Easy, Illya," Shirou murmured, his voice soothing despite the urgency in his tone. "Relax for me."

With gentle persistence, he pushed into her, feeling her body slowly give way. She whimpered, her hands clutching the bedsheets tightly as he inched deeper. He took his time, not wanting to hurt her, his movements slow and deliberate.

Miyu watched with a mix of excitement and envy as her brother's cock disappeared into Illyasviel's ass.

"Don't forget about me and Chloe," she said, her voice a seductive purr.

Shirou couldn't ignore the invitation in Miyu's eyes. He reached out, his left hand sliding over the soft curve of her hip. He gently inserted a finger into her asshole, feeling her quiver beneath his touch. She moaned softly, pushing back against him, urging him deeper.

With his other hand, he reached out to Chloe, who was eagerly waiting her turn. He slid a finger into her tight asshole, her cheeks clenching around his digit. She whimpered, her body already sensitive from her recent orgasm. He began to pump his fingers and his cock in and out of all three of their asses, setting a slow, steady rhythm.

The room was filled with the sounds of their mingled moans and gasps, their breaths coming in short pants as they pushed into one another's most intimate spaces. Shirou felt a sense of power and love, a heady mix that had him reeling. He began to move faster, his cock sliding in and out of Illyasviel's ass with ease as his fingers worked their magic on Miyu and Chloe.

Miyu's eyes rolled back in her head as she felt her brother's digit push into her, stretching her open. She couldn't help but moan, the sensation of his finger inside her while watching him fuck their sister adding to her own arousal. Chloe was equally lost in the moment, her eyes glazed over with desire as she felt the pressure of his thumb on her own anus.

Shirou's hips picked up the pace, his cock now moving in and out of Illyasviel's ass with an easy, practiced rhythm. He felt her body begin to relax, her whimpers turning into soft moans of pleasure. He knew she was close, her muscles contracting around him in a delicious vice grip.

"Big brother," she whispered, her voice strained with need. "Fuck me harder."

Shirou complied, his hips moving with more urgency as he claimed her ass. Illyasviel's moans grew louder, her body responding to his every thrust. He could feel her tightening around him, her orgasm building with each passing second.

Miyu and Chloe watched with rapt attention, their own need growing with each moan that escaped Illyasviel's lips. Shirou could feel their eyes on him, the heat of their desire almost tangible.

He focused on Illyasviel, his cock driving into her with a **** that was both punishing and loving. Her body began to quake, her moans growing louder. He knew she was close, her muscles tightening around him.

"Cum for me, Illya," he groaned, his own need building. "You two, Miyu, Chloe. I want to feel all of us cum together."

Illyasviel's moans grew more insistent, her body tightening around him as she neared her climax. Shirou could feel her muscles contracting, her asshole squeezing his cock in a delicious rhythm. He knew she was close, her whimpers turning into cries of pleasure.

Miyu and Chloe watched with bated breath, their own bodies moving in sync with the rhythm Shirou had set. He felt their asses clench around his fingers, their desire palpable. He pumped into Illyasviel with a newfound urgency, his fingers working faster on Miyu and Chloe's assholes.

"Ahh," Illyasviel's voice grew louder, her body arching back as she reached the peak of her climax. The muscles in her ass tightened around his cock in a powerful spasm. The sensation was overwhelming, pushing him closer to the edge.

Miyu and Chloe watched with bated breath as Illyasviel's orgasm washed over her. They could feel the tension in the air, the heat of their own desires reaching a boiling point.

Miyu, feeling the need for release, began to push back against Shirou's finger, her hips rocking back and forth as she sought the same intense pleasure she knew her sister was experiencing. Chloe, not wanting to be outdone, did the same, her breath hitching as she felt her body start to respond to the sensation of his digit in her ass.

Shirou could feel their bodies tensing around him, their muscles clenching and releasing in time with his thrusts. He knew they were all close, their desire for each other reaching a crescendo. He leaned back, his cock still buried in Illyasviel's ass as he watched Miyu and Chloe's bodies move in unison.

Miyu's breaths grew shorter, her cheeks flushed as she pushed back against his finger, her asshole tightening around it. Her eyes met his in the mirror, and she gave him a pleading look. He knew what she wanted, and he was more than happy to oblige. He added another finger, stretching her wider, feeling the slickness of her lube-covered anus as she took him in.

Her moans grew louder, her body moving in perfect sync with his rhythm. He watched in the mirror as her hand reached between her legs, her fingers playing with her clit in time with his movements. She was close, so close. He could see the desperation in her eyes, the need for release.

Chloe, equally lost in the moment, began to rock her hips back against his thumb, her breath coming in short gasps. He knew she was feeling it too, the pressure building in her ass as she approached her own orgasm.

The room was a symphony of moans and gasps, their bodies moving together in an erotic dance that was both beautiful and intense. Shirou could feel his own climax approaching, his balls tightening as he watched the two of them.

With one final push, Miyu's eyes went wide, and she screamed out her release. Her ass clamped down on his fingers, her body trembling as wave after wave of pleasure crashed over her. Chloe wasn't far behind, her own orgasm taking her by surprise as she felt Shirou's thumb press against her pussy. Her body jolted, her pussy spasming as she came, her juices coating his hand.

Shirou could feel the tension in the room break as they all reached their climaxes. Illyasviel's body went lax, her breath coming out in shuddering gasps as she felt her brother's cock still pulsing inside her ass. She looked over her shoulder at him, her eyes glazed with pleasure.

Miyu's orgasm was equally intense, her body shaking as she felt the waves of pleasure wash over her. She bit her lower lip, her eyes screwed shut as she rode out the intense sensation. Chloe's body jerked, her muscles seizing up as she felt the explosion of pleasure from her own orgasm.

Shirou watched them both, his cock still buried in Illyasviel's ass, feeling the aftershocks of their shared climax. He knew he was close, his balls tightening with each pulse of pleasure from his sisters. He pulled his fingers out of Miyu and Chloe's asses, reaching around to wrap his hand around his cock, now slick with Illyasviel's juices.

With one last, powerful thrust, he pulled out of her, aimed it at the small of her back, his hand moving in fast, jerky motions as he painted her with ropes of white hot cum. It splattered onto Illya's skin, then Miyu's, and finally Chloe's.

They all moaned in unison, their bodies trembling with the aftershocks of their shared release. He watched as their skin glistened with his seed, a visual representation of the love they all shared.
