At the same time, Bastet watched, her tanned felinid tail flicking wildly behind her butt, a dangerous counterpoint to the controlled elegance of her posture.

She was watching how Kaiden was dominating his second monster lover and could not help but imagine herself in Calypso's place.

With her Master's new, overwhelming demonic form, the felinid knew she would be utterly destroyed.

Her poor little catlike tail would not be able to mount any form of resistance against his massive one. And his giant cock... she'd be broken. A deep, internal heat rose, and a slick, silent wetness stained her black panties at the thought.

Indeed, it was not just Nyx who was the ultimate submissive girl.

Lastly, Aria watched Calypso with narrowed, squinted eyes.

The moment her jealous rage subsided, her tactical mind took over. She was studying her new love rival, intent on learning her strengths and weaknesses to prepare for the future.

She watched Calypso's immense pleasure, the way the Level 100 demoness shrieked in fulfillment, and she clicked her tongue in cold annoyance. "Tch!"

The Moon Valkyrie came to the same, devastating realization as Bastet. With Kaiden's new, overwhelming frame, she and the other human girls were simply not fit to welcome him into their folds. He would not even get halfway before hitting the walls of their wombs.

He would not have a good time lying with them, and probably neither would they enjoy the act. It would be miserable for all parties.

The mere idea that she was unfit to embrace the love of her life nearly made the yandere enter a second fit.

What made it all the worse was that Calypso was a large demoness and also much stronger than they with her hundred levels. She could welcome him... barely. She was being utterly destroyed, yes, but not in the deadly way they would be if Kaiden went even a tenth as hard on them as he did on her.

Aria's hand instinctively went to stroke her stomach, her fingers tracing the smooth metal of her armor above her womb, where Kaiden's mark of possession was etched in the form of a demonic womb tattoo.

Her voice was a low, desperate whisper, a plea sent to the being from across the battlefield.

"Give me a way to transform into a demon too, Kai... Dummy…"

The yandere princess was ready to throw her humanity away on a whim if it meant remaining fully compatible with the love of her life.

…

The sheer force of the thrust had sent Calypso into a shriek.

She was suspended high above the ash floor, impaled on the throbbing might of the Omni Cock, held effortlessly aloft by the demonic coil of his tail around her waist. Her feet dangled, and she became a vessel of ecstatic torment.

Kaiden's massive hands, released from her throat, descended slowly. They settled on the twin globes of her sensual, demonic ass. Grabbing onto them filled his head with a heavenly sensation.

He began to knead and massage the dense muscle, testing the firmness of her flesh and finding immense satisfaction in the feel of his new prize. His fingers dug in, shaping and claiming, adding a layer of tactile, possessive pleasure to the deep internal devastation.

Calypso leaned down. Her focus was entirely on her Lord. She sought out his lips for a second, needy kiss. Their tongues met in a hot, desperate swirl, their eyes locking as their mouths mated. In the crimson depths of her gaze, the blissful rapture was suddenly mixed with a flash of pure mischief.

In that split second, she felt the frantic, building tension in his penis, the unmistakable sign that his release was imminent.

With a superhuman burst of speed, fueled by her cunning and demonic power, Calypso used the rapid momentum of his final thrust and her weakened state to wrench her waist free from his tail.

She slipped cleanly out of the tail's hold just as his body seized with the beginning of his climax. The demoness flipped in the air, landing lightly on her knees with her back to him, and her own tail shot out, whipping around his neck in a swift, binding grip.

She was using his momentary weakness, the loss of control during orgasm, to stage an immediate, playful coup.

Calypso twisted her head back, and a wide, challenging grin split across her gorgeous, heated face.

Kaiden's red eyes darkened instantly and dangerously, just as she wanted. His massive body, already throbbing through climax, coiled with fury. He was having his power play usurped, his dominance questioned.

He would not have it.

His two hands shot out and found the soft flesh of her waist. Using the tight grip as leverage, he slammed the woman back down onto his cock mightily.

The force of the impact was devastating.

It drove her so deep and so violently that Calypso's senses exploded, and she released the largest, most shattering shriek of her life. "GGHHHHAAAAAAANNGNGGGHHHH❤️❤️❤️❤️!!!!!!!"

An ocean of demonic fluids gushed out, soaking his cock and the ash ground beneath them. She went unconscious for a moment. Her body was trembling incessantly, becoming a beautifully ravaged ruin of a previously graceful, mighty, and proud woman's excellent form.

Even as her conscious mind fled, her body remained loyal to the challenge. Her tail, still wrapped around his neck, tightened again playfully, wrestling for the dominance she craved to lose.

Calypso didn't know it herself until now, but she realized with a terrifying joy that she was a bad, bad woman. She'd already been disciplined for playing with her sister-wives in the way she did, and now this…

But she simply couldn't help herself. Getting dommed into oblivion was the best thing that had ever happened to her life - besides being accepted by her new lover, of course. She had to egg him on to do her as raw and wild as possible.

The violent, frenzied mating continued for what felt like an eternity, likely more than an entire hour.

The initial challenge had passed, replaced by a deep, consuming rhythm of pure, dominant possession. Kaiden's immense power poured into her, and Calypso, regaining consciousness, met every thrust, every demanding grunt, with a cry of ecstatic surrender.

They stared into each other's eyes. His, a blazing, unyielding red; hers, a mixture of tears, sweat, and absolute, devoted rapture.

By the end, Calypso was a pure, beautiful mess.

Her once neatly kept black hair was an unruly, tangled cloud; her entire body glistened with sweat and an abundance of her own demonic fluids.

Dark bruises marked her neck from the demanding strangulation, and her skin, usually hard and flawless, was flushed a furious crimson from the sustained ravaging. She was a ruin of a previously graceful, mighty, and proud woman, yet she had never felt more utterly fulfilled.

But she wasn't the only one who had changed.

As the mating reached its final, prolonged intensity, Calypso watched her man with the eyes of a woman deep, deep in love. The massive, bulging muscles of Kaiden, the Great Demon of Wrath, were slowly beginning to recede. The demonic markings faded, the towering height lessened, and the monstrous intensity in his red eyes softened, replaced by a lingering exhaustion.

He was slowly losing his demonic trance and form.

With a final, shattering union that left both of them breathless, Calypso clung to the man who now lay on top of her. She wrapped her arms tightly around his body, pulling him into a wet, desperate kiss.

"I will never leave your side, my Lord and Husband," she declared right into his ears. Her voice was thick with emotion. Her eyes became blurry with tears as she repeated,

"Never."

As the last vestiges of the Great Demon's aura dissipated, a wave of familiar, systematic magic washed over Kaiden, followed by a sharp, crisp sound in his mind.

A block of ethereal blue text appeared in his fading vision:

[Ding!]

[You've subjugated Calypso, the Infernal Matriarch! (Level 100).]

[Subjugated monster girls: 2/3]
