Irisviel Von Einzbern

Shirou stepped into the dimly lit room, his eyes taking a moment to adjust to the stark contrast from the bright hallway.

But even in the half-light, Shirou could make out the silhouette of the woman sitting on the edge of his bed.

She was dressed in a flowing white, same as her hair that cascaded over her shoulders, a stark contrast to the shadowy surroundings. Her eyes, a piercing red, met his with a look of intensity that sent a shiver down his spine.

Shirou recognized her immediately as Irisviel von Einzbern, the enigmatic homunculus who in an another world would be considered his mother.

Luckily the one in front of him has never met Emiya Kiritsugu.

The air grew thick with a tension that was palpable, charged with the unspoken desires that hung between them.

Shirou's breath hitched as Irisviel stood from the bed, her movements fluid and graceful, the fabric of her gown whispering against her skin. She approached him with a purpose that was undeniable, each step deliberate and filled with intent.

Without a word, she leaned in, pressing her full, soft lips against his. The kiss was gentle at first, a question in itself, but as Shirou responded with equal fervor, she deepened it, her tongue slipping into his mouth, exploring and claiming.

Shirou's hands found their way to Irisviel's waist, pulling her closer as the passion between them grew. He could feel the heat of her body through the fabric of her gown, and his cock grew hard in his pants, straining against the material. She stepped back just far enough to let him see the hunger in her eyes, and with trembling hands, she began to undo her dress.

The gown fell to the floor in a pool of white, revealing her naked form. Her skin was pale, and her breasts, perky and full, bounced slightly as she moved.

Without breaking eye contact, Shirou stepped closer, his own shirt and pants soon joining the discarded fabric on the ground. He took in her beauty, his eyes tracing every curve and line, committing her to his memory.

Their bodies and lips met once again, and this time, there was no pretense of innocence or hesitation. Irisviel's hands slid down his back, gripping his firm ass, urging him closer. He felt her warm, wet pussy press against his thigh, and with a groan, he lifted her up, her legs wrapping around his waist.

Their kiss grew more urgent as Shirou carried her to the bed, laying her down on the cool sheets. Her skin felt like silk under his touch, and he couldn't resist the urge to run his hands over her body, feeling her respond to his every touch. Her breasts were in his face, and he took one of her nipples into his mouth, suckling and teasing it with his tongue until she gasped.

Irisviel's hands roamed over his body. He could feel the wetness between her legs, and the scent of her arousal filled the air. His cock was rock-hard, demanding release, he positioned himself between her legs, aligning the tip of his cock with her entrance.

With a deep, needful moan, Shirou pushed inside her, feeling the tightness of her pussy give way to his length. Her eyes widened with a mix of pleasure and surprise, but she didn't pull away. Instead, she wrapped her legs around his waist, urging him to go deeper. He began to move, setting a rhythm that grew more intense with each passing moment.

Her nails dug into his back as he fucked her, their bodies moving together in a dance as old as time itself. The sound of their skin slapping together filled the room, a primal symphony that echoed in the silence. Her breasts bounced with every thrust.

Shirou could feel her pussy tighten around him, her muscles clenching and releasing in a silent plea for more. He gave it to her, driving deeper, harder, faster. The headboard knocked against the wall in a staccato beat that matched their ragged breathing.

Her moans grew louder, a symphony of pleasure that spurred him on. He watched as she threw her head back, her mouth open in a silent scream of ecstasy. He leaned down to kiss her neck, sucking and biting, feeling her pulse race beneath his lips.

With a growl, Shirou pulled out of her, flipping her onto her hands and knees. She looked at him over her shoulder, her eyes glazed with lust, and he knew she was ready for more. He positioned himself behind her, his cock standing tall and proud, and slammed back into her once again.

The new angle sent shockwaves through both of them, and she yelped, her hands gripping the sheets. He reached around her, one arm wrapping tight around her neck, the other playing with boobs, pinching the nipples, rolling them between his thumb and forefinger.

With each thrust, he felt her body tighten around him, her pussy squeezing him like a vise, urging him to climax. But Shirou was in control, his movements deliberate, holding back for as long as he could. He wanted to draw out the moment, to savor the feeling of her body against his.

Irisviel's breath came in short, ragged gasps as she pushed back against him, meeting his rhythm.

He felt his control slipping.

With a snarl, Shirou tightened his arm around Irisviel's neck, holding her in place as he drove into her from behind. The angle was perfect, hitting all the right spots, making her body shudder with every thrust. She pushed back against him, her pussy clenching around his cock like a fist, trying to milk him dry. He could feel her getting closer, her breaths turning into moans, her body tensing up.

Her walls tightened around him, signaling her impending orgasm, and he knew he couldn't hold out much longer. His balls ached with the need to release, and he felt the warmth building up inside him, threatening to spill over. He leaned down, his chest pressing against her back, and whispered into her ear, "I'm going to cum inside you, Iri."

Irisviel's response was a strangled moan, her body trembling with anticipation. Shirou felt the first spurt of cum shoot out of him, filling her completely. He stilled for a moment, savoring the sensation of her pussy convulsing around him, her warmth gripping him tightly as she climaxed with him.

Her orgasm washed over her in waves, each one more intense than the last. She collapsed onto the bed, her legs giving out from under her, taking Shirou with her. He remained buried inside her, his cock still twitching as he emptied himself completely.
