Story: 

After completely merging with Irisviel, I felt the surge of limitless power coursing through me. With Ruby and my mother's combined strength, I knew I could finally break through the barrier and merge with Tiamat. As I reveled in the sensation of my newfound divinity, Ruby's presence brought me back to focus.

"Ruby," I called out, my voice resonating with newfound power. "Now that we've merged with Irisviel and gained this immense power, it's time to pursue our ultimate goal. With the vessel we've acquired, we can break through Tiamat's barrier and indulge in the irresistible pleasures her divine form promises. We need to discuss how we'll do it."

Ruby, in her form as the Magical Stick, shimmered in response. Her white wings fluttered with anticipation as she hovered in the air, the yellow star in the ring glowing brightly. "Of course, Illya," she replied, her voice filled with mischievous enthusiasm. "Breaking through Tiamat's barrier and merging with her essence is the final step in our journey to unlock your true potential. We must proceed with caution."

"Before we proceed, Illya," Ruby interjected, her tone becoming more serious, "we must address your current form. While merging with Irisviel has granted you incredible power, it has also altered your physical appearance, giving you a more developed adult body."

I nodded, grasping the implications. "I understand. We can't afford to raise any suspicions."

"Exactly," Ruby affirmed. "To blend in and gather information about Tiamat's whereabouts without drawing attention, you must revert back to your normal form. Remember, you only needed the power, and you've obtained it. However, the essence, memories, and power of the Grail still remain within you."

With determination, I focused my thoughts, channeling the essence of the Grail within me. Slowly, the transformation began, my form shifting and contorting until I returned to my original appearance. Though my exterior had changed, the power and knowledge I had gained remained intact, a potent reminder of the journey I had undertaken.

After returning to my original form, Ruby and I set out on our quest to find Tiamat. Together, we navigated through the corridors of Chaldea, our senses attuned to the faintest whispers of Tiamat's presence. With each step, anticipation coursed through me, mingling with the thrill of the impending encounter.

As we ventured forth in search of Tiamat, Ruby and I exchanged words of anticipation and determination.

"So, Illya, any leads on where our big friend might be lurking?" Ruby's voice echoed in my mind, her tone tinged with mischievous curiosity.

"Not yet, Ruby," I replied, my senses keenly attuned to the faintest traces of Tiamat's presence. "But I can sense her lingering nearby, like a whisper in the shadows of Chaldea."

Ruby chuckled softly. "She's certainly not making it easy for us, is she? But then again, when has anything ever been easy for us?"

I nodded in agreement, the thrill of the impending encounter coursing through me. "True enough. But we've faced tougher challenges before, haven't we? And this time, we have the power of the Grail on our side."

Ruby hummed in acknowledgment. "Ah, yes, the power of the Grail. A formidable force indeed. But let's not get too overconfident. Tiamat is no ordinary servant."

I paused, considering her words. "You're right, Ruby. We must proceed with caution. Tiamat may be powerful, but she's not invincible. With our combined strength, my mother's essence and power of grail, we'll find a way to absorb her."

Finally, after what felt like an eternity of searching, we found her.

Tiamat stood before us, her presence both awe-inspiring and intimidating. As I gazed upon her divine form, I couldn't help but be captivated by the supple curves of her body, the way her movements seemed to flow with an effortless grace.

Taking a deep breath to steady myself, I approached Tiamat, determined to keep her occupied while Ruby worked her magic. Engaging her in small talk, I subtly guided the conversation, keeping her attention focused on me as Ruby channeled the power through me and the Grail.

As I delved deeper into conversation with Tiamat, Ruby's magic worked tirelessly to break through the formidable barrier that still surrounded her essence. Despite the immense power we wielded, the barrier remained resilient, stubbornly resisting our efforts to breach it.

But with the combined power of the Grail and Ruby's unwavering determination, we finally managed to crack through the barrier. As the barrier shattered, a surge of energy rippled through the air, alerting Tiamat to our presence.

In that fleeting moment, Tiamat took a defensive stance, her eyes narrowing as she prepared to face us in battle. But it was too late. Ruby had already completed her spell, and with the power of the Grail coursing through me, absorbing Tiamat became effortless.

A brilliant flash of lightning illuminated the scene as Tiamat's essence began to merge with my own. With each passing moment, her divine form grew smaller and smaller, shrinking into a mere fraction of its former size as it was absorbed into my own body.

And as the last remnants of Tiamat disappeared into me, I could feel the energy surging through my body, intertwining with Tiamat's essence in a sensual dance of power and desire.

A low moan escaped my lips as I felt the first tendrils of Tiamat's essence merging with my own. It was a sensation unlike any other, a heady mix of pleasure and power that left me trembling with anticipation.

A sudden shift swept through my body, and I felt my form contort and reshape itself in ways I could not comprehend. Atop my head, where once there were none, now stood small yet prominent horns, a testament to the merging of my essence with that of Tiamat. But Instead of the divine, voluptuous form of Tiamat, I found myself taking on the features and form of her younger self—a realization that filled me with bewilderment and frustration.

Confusion gnawed at me as I stared down at my newly transformed body. "What... What is this?" I demanded, my voice tinged with incredulity. "Why do I resemble Tiamat in her youthful form?"

Ruby, hovering nearby, shimmered with uncertainty as she attempted to offer an explanation. "It seems that the fusion process has resulted in a... unexpected outcome," she ventured, her tone hesitant. "Perhaps the power of the Grail has influenced the transformation in unforeseen ways."

But despite Ruby's attempts to assuage my concerns, I could not shake the sense of disappointment that washed over me. To have come so far, only to be met with this unexpected twist of fate, was a bitter pill to swallow.

As I grappled with the shock of my unexpected transformation, Ruby's mischievous voice broke through my thoughts, offering a tantalizing suggestion. "Perhaps," she purred, her tone laden with suggestion, "if you were to indulge in the pleasures of your new body, you might unlock the ability to transform it at will, much like Tiamat herself."

Her words sent a shiver down my spine, stirring a potent mixture of curiosity and desire within me. The idea of exploring the depths of my newfound power through the sensual delights of my transformed body ignited a primal longing deep within my core.

With a mixture of trepidation and excitement, I allowed myself to succumb to Ruby's suggestion, surrendering to the intoxicating allure of my altered form. As I tentatively explored the contours of my body, I felt a surge of pleasure coursing through me, igniting a fire of desire that burned hotter with each passing moment.

"Ah, Tiamat," I whispered, my voice laced with desire as I caressed my own form, I felt the boundaries of my own limitations begin to blur, the lines between myself and Tiamat's essence fading into obscurity. The sensation of my body responding eagerly to the primal urges that pulsed within me, urging me to explore the depths of my newfound power.

As my body responded to sensual urges, urging me to explore the depths of my newfound power. I became keenly aware of the younger Tiamat within me, finally giving way to the adult form that now asserted its dominance over my own. Heat radiated from every pore, intensifying the sensations of arousal that pulsed through me with each passing moment. "Your essence, it's intoxicating. I can feel it mingling with mine, urging me to explore every inch of my newfound power."

With each passing moment, I could feel my form expanding and growing, the supple curves of my body reshaping and contorting in response to the overwhelming surge of energy that coursed through me.

I gasped, my hands wandering over my curves as they swelled and shifted in response to the overwhelming surge of energy. "I can't resist it. The power, the pleasure... it's overwhelming."

Their soft mounds of my merged form expanding with each beat of my heart, filling out with the voluptuous curves of Tiamat's adult form. A rush of heat flooded my senses, and I found myself growing more aroused with each passing moment, unable to resist the urge to explore the changes that were overtaking me.

My body resembling the young Tiamat was now becoming more like the form of Tiamat I desired, the once-youthful features of her form finally changed. It was a transformation of exquisite beauty and sensuality, a testament to the boundless potential of my divine existence.

 "Ah, Tiamat," I whispered, my voice laced with desire as I caressed my enhanced form. "Your essence, it's intoxicating. I can feel it mingling with mine, urging me to explore every inch of my newfound power."

My hands moved of their own accord, trailing over the newly formed contours of my body, fingers grazing lightly over the now-full curves of my breasts and the rounded swell of my hips. I couldn't help but gasp as pleasure surged through me, the sensations heightening with each caress, each touch sending sparks of ecstasy racing through my veins.

With each transformational shift, I surrendered myself to the exquisite pleasure of the moment, my body embracing the divine essence of Tiamat with eager abandon. "Yes," I moaned, my voice filled with longing and desire. "Give me more. I want to feel it all, every sensation, every ecstasy that comes with embracing your divine essence."

As the crescendo of pleasure reached its peak, a radiant glow surrounded me, illuminating the space around me with an otherworldly light. In the midst of this ethereal glow, Ruby appeared before me, her form shimmering and shifting until she transformed into a big hand mirror.

With a playful twinkle in her eye, Ruby held the mirror out to me, her voice a melodious whisper in my mind. "Look at yourself, Illya," she urged, her tone filled with mischievous delight. "See the true goddess that you have become."

With trembling hands, I took the transformed ruby mirror, holding it up to gaze upon my reflection. What I saw took my breath away—a vision of beauty and power that surpassed anything I had ever imagined.

No longer confined to the petite form of my youth, I stood tall and commanding, my figure exuding a divine sensuality that mirrored the essence of the ancient goddess. My curves were fuller, my features more pronounced, radiating with an irresistible allure that spoke of untold pleasure and desire.

With a gasp of realization, I understood that Ruby's suggestion had unlocked a transformation within me, allowing me to fully embody the adult version of Tiamat. And as I gazed upon my reflection in the mirror, I knew that I had unlocked a new level of pleasure and power, transcending the limitations of my mortal form. No longer confined to the petite frame of my youth, I stood as a goddess incarnate, my figure exuding a divine sensuality that mirrored the essence of the ancient deity, Tiamat.

But the transformation was more than just physical. With the soul of Tiamat coursing through my veins, I felt a newfound connection to her essence—a connection that granted me the ability to access both her younger and adult forms at will. It was a tantalizing prospect, one that promised endless possibilities for exploration and indulgence.

Yet, as I reveled in the boundless pleasure that awaited me, a darker thought began to creep into my mind—a whisper of temptation that stirred the depths of my desires. With access to Tiamat's essence and the power of grail bestowed upon me by my mother, Irisviel. I realized that I held the key to a greater conquest—a conquest that extended beyond the confines of my own desires.

The limitless power of the Grail, infused within me after absorbing Irisviel, began to exert its influence, twisting and distorting my desires with its insatiable hunger for power and pleasure.

With each passing moment, I felt the tendrils of its influence seeping into my consciousness, corrupting me from within and fueling a hunger that knew no bounds. The primal urges of Tiamat's essence, combined with the overwhelming surge of power from the Grail, merged within me, transforming my desires into something darker, something more sinister.

And as the realization dawned upon me, I knew that I could not resist the allure of my newfound power. With the ability to merge with any heroic spirit in Chaldea, to indulge in pleasures beyond imagination, I felt a hunger stirring deep within me—a hunger that demanded satisfaction at any cost.

But as I embraced the darkness that pulsed within me, I saw a flicker of concern in Ruby's eyes—a concern that spoke of the danger that lurked beneath the surface of my desires. What had begun as a mere prank, a playful suggestion to indulge in pleasure, was now taking on a life of its own—a life that threatened to consume me whole.
