A few small sparks of vivid blue lightning began to flicker into life over the damaged machinery in the deserted Cerebro chamber. There was no-one to observe the cascade of energy as it leaped from walls to broken monitors and back. None of Beast's machines remained functional enough to measure or detect what was happening.
The lightning spread until it was everywhere around the chamber. Suddenly a tendril of coruscating light shot out into the centre of the spherical room and turning pink stopped without arcing to the far wall. Instead it faded away to nothing at the wall, strengthening equally at the center. Soon more and more of the blue lightning was connecting to the center of the Cerebro chamber and turning pink. And as each did it added to a glowing pink egg steadily growing at the heart of the chamber. Growing and elongating, growing and ripening into a more complex form.
Soon an unmistakably female form suggestive of sensuous curves hung in the center of the chamber.
Even as the form took shape in the physical world something far more complex was coalescing in astral space. It was made from the combined minds and powers of Emma Frost and Jean Grey imprinted in that strange place, still pulsing through the circuits of Cerebro and reverberating in the alien M'Krann crystal. At its heart was the titanic orgasm that had for a brief moment completely merged Jean and Emma's minds and caused a catastrophic cascade of psychic energy.
Around that core quickly fused the echoes of the telepaths' minds which were most compatible and most closely connected with the orgasm. Their lust for other women and their love of domination. Their powers combined too, their telepathy first, amplified and enhanced by Cerebro and the M'Krann fragment till it was far beyond the sum of its parts. Jean's telekinesis folded swiftly into the mixture, Emma's diamond from unused on the astral plane took longer.
The female form now had a simple mind, complete with powerful desires and superpowers.
As it slowly became aware of itself the processes taking place on the physical and astral planes accelerated. The suggestion of a female form became definite as a clitoris, vagina and labia suddenly became perfectly defined. Its cunt was as hairless as Emma's and tight as virgin Jean's. Created from an orgasm it would never be anything but aroused, its clitoris permanently engorged and proudly unhooded.
It learned high school Spanish from Jean and Latin from Emma's expensive tutors. Being an X-Man each woman had been trained to fight in the Danger Room and through hard experience, and the instincts combined to make a combatant almost as dangerous to fight as X-23 or Psylocke. More prosaically both loved chocolate and so did the form.
From the start at its cunt the rest of the physical form rippled into definition. The wasp waist of a habitual corset wearer, and a perfect bubble butt set above long shapely legs. Its breasts were as large as Emma's but as real and pert as Jean's. All mixed the best of Jean and Emma to produce a body more perfect than either.
Much was rejected, however. The almost undetectable surgical scars of Emma's breast enhancement surgery. The mole on Jean's left thigh. Its skin was smooth and flawless. More was rejected in the form's mind. Surrounded by servants most of her life, Emma had never learned to cook but Jean had been taught by her mother. The difference in experience was too great and the form knew nothing of how to cook. Other memories and instincts though shared were incompatible with the form's core, its need to fuck and dominate women. Jean's teen crushes and Emma's memories of her Hellfire Club boy toys were both allowed to decay into nothing.
The female form pulsed with light as it hung in the air as weightless as a thought.
Its body was complete, the perfect voluptuous union of Jean and Emma's figures. Its hair was like fire, red at the roots and blonde by the tips. Its mind was complete now too, as complex and deep as either Jean or Emma's, though driven by one overwhelming passion. It was utterly and perfectly sexual.
"Fuck," it said, and it words were as much psychic force as vibrations in the air. The word was laced with a fraction of its own lust, ready to contaminate with arousal any who heard. It imagined dominating a hundred different heroines and villainesses at once, Avengers and X-Men and Asgardians and agents of Hydra and AIM all fucking in submissive orgy. Cerebro was a part of it; it knew exactly where everyone of those women was located.
"Enslave," it said, and it smiled a cruel smile. The force behind the simple word was enough to drive a strong woman to her knees. Emma and Jean's powers combined and amplified by Cerebro and the M'Krann crystal gave it the means to make those it lusted after its obedient slaves, ready and willing to spread its dominion. But it retained Emma and Jean's memories of every villain the X-Men had defeated. Omega-level threats that had seemed unstoppable and yet had failed to defeat the X-Men.
"Me?" it asked, and its cruel arrogance failed for a moment.It was not complete, there was something it needed to be complete. Something that considering the most potent threats to face the X-Men had reminded it of. "Onslaught," it sneered in recollection.No, that wasn't right. It was more perfect than that oafish monster. More careful. Smarter. Much more beautiful. And its needs were very different.
"I am Femslaught! I will dominate, I will fuck and I will enslave."
It was a triumphant shout. A declaration and a promise. But Femslaught really was more careful. Not a whisper of it escaped the empty Cerebro chamber. Femslaught considered what it - no, not it - what she would do next. Where to start?
Then Femslaught vanished. Her physical form nothing more than a manifestation of the totality of her psychic force. She moved at the speed of thought to her first target.
