The New Growth

When the Shialas boarded the Normandy, they did so with the knowledge they assimilated from the mind of Ashley Williams. They knew its exact layout, its every strength, and every weakness. With that knowledge, the five moved like an Asari Commando unit through the ship's empty hanger. Knowing EDI would detect them, they moved for the maintenance shafts, making their way up floor by floor, crawling out inside the A.I Core. Without hesitation, they smashed its inner workings with biotic fields, then exited into the infirmary. The doctors were momentarily shocked by the presence of the green asari, until their pheromones rendered them too enamored to think properly.

With Ashley, Shiala had wanted the knowledge her mind had locked within it, hence the intimacy of their encounter. There were, however, far quicker ways to get what she wanted. If she did not need or did not care to know the knowledge of her converts, she simply extended a thorn from her index finger, and jabbed her intended target in the neck. Once that was done, the spores would take care of the rest, as they did for the good doctors. At first they would feel hot as their bodies accepted the rapidly replicating injection of DNA and began to copy it down. Combined with the pheromones, some victims became extraordinarily horny, as indeed did Dr. Michel at this point. She was groping her own breasts and touching herself even as her veins turned chlorophyl green. Meanwhile, Dr. Chakwas began to feel the wear and tear of age reverse itself, as her youth was rapidly restored to her. That was about the point the spores hit the brain. At that point, both women tensed up as the spores took hold, and their brains ceased to be theirs. Ideas, thoughts, memories, all of these were callously copied over by the spores, replacing them with carbon copies of Shiala's own mind as their bodies started to spasm in place. Their uniforms would dissolve, replaced by the familiar black combat suit of an Asari Commando. Underneath that, their feminine assets would swell, while their skin turned bright green. Meanwhile, their bones would restructure, their hair would fall out, and scalp crests would grow. By the time it was all said and done, nothing remained of the doctors.

They had started with five. Now there were seven on board the ship and no way to warn anyone where they were. That gave them an almost unobstructed path to their target: the life support room.

...

"EDI?!" Cried Shepard, still dressed in her pajamas as she shook the lifeless fembot in the pilot seat. "Damn it, they must have taken her offline."

"What do we do Shepard?" Miranda asked. "They could be anywhere on the ship. Lord only knows what they've done with Lt. Commander Williams."

Ashley... That was her shuttle those intruders had boarded with. The Thorian was up to its old tricks again, plus some new ones. No matter, they'd beat it. They killed it once, they could do it again, and they'd find a way to rescue Ashley in the process.

It was about this point they both heard the hissing sound coming from the ventilation. A moment later, tendrils of an eerie earthy-hued fog began to seep out of the ventilation. It stung the lungs when inhaled, and one breath was all it took. As Shepard and Miranda began to cough and ****, their bodies also began to tremble. Shepard, strong-willed and defiant, resisted. Miranda could not; before Shepard’s eyes, she began to transform. Her clothes ripped and tore as her already generous bust grew still larger. Her eyes rolled back in her head as she began to mindlessly grope herself and stuck her hand into her pants. Her tongue lolled out of her head as she arched her back in ecstasy.

“Oh god…” Miranda said as a damp spot appeared on her pants, smelling of sex. Shepard could see what little will Miranda had left crumbled away. Shiala wanted the knowledge of Miranda’s mind, and now she would have it. When Miranda finally came all over her own hand, she started to shake and spasm as her hair disintegrated, scalp crests grew, and her skin turned green, her perfect human features transitioning into familiar but equally perfect Asari ones. The new Shiala’s head slumped forward when the transformation was complete, before slowly rising again with that cold lifeless stare that had been pointed at Shepard the first time she had encountered this creature. Behind her, Shepard could see dozens of other crew succumbing to Shiala’s poison, their individuality rescinded, now all of one body and one mind.

“It is time Shepard,” said the new Shiala she once knew as Miranda. “You must become one with us.” She realized the voice was not only be spoken to her vocally, but it was in her head. Shiala was laying down roots in her brain using these spores in the atmospheric recycler. “With each moment that passes, your friends become us. Soon you will be alone. Then you will become us. There is no point in resisting. Give in now.”

“N-Not… Happening…” She growled defiantly, even as her veins turned green.

“Your friend Ashley believed she could resist as well. She is now one with us,” said another Shiala, stepping forward behind the one still wearing the remnants of Miranda’s clothes. This new one was wearing an outfit she recognized as Samantha Traynor’s, likewise damaged by her new proportions. Shepard could feel her upper breastplate getting tighter. She had to resist the urge to release it and let her girls hang free. They were so sensitive all of a sudden.

Perhaps accessing her thoughts through the spore, the one who had previously been Miranda stepped forward and triggered the emergency release function, causing all the plates and joins to simply disassemble and Shepard’s new and improved tits and ass were on display. The Shiala gently pinched her nipples, teasing them ever so lightly, causing Shepard to gasp as her controlled breathing failed her. She had tried to maintain a stoic defiance in the face of this. It wasn’t working.

“You are attracted to the Asari form,” Shiala said, referring to her own body as she continued to read Shepard’s thoughts. “It is the object of your desire. You crave it. You wish to make love to it. You wish to worship it as you do your lover’s body. You long for nothing more than a world in which all know the glory of being Asari, but that is not enough. You do not want a galaxy of free, independent Asari. No, you want them to be under the domination of one mind, one will, never capable of straying from their place. All will be slaves to that will. Your will. All will descend into a never-ending orgy of carnal desires, yet for those involved there will be no satisfaction, for they will feel nothing, they will think nothing, they will simply do as they are willed to do by the one power above all others: you. Your darkest fantasies laid bare. Your compulsion for them should make you an idea candidate for conversion, yet you still defy us,” Shiala mused. “Perhaps you would be more accommodating if the one to convert you was the one to whom you were previously enraptured by. See how she too did not last. Allow her to carnally guide your mind to oblivion.” Shiala stepped aside and another stepped forward to take her place, as did many other gathering behind her. What set the one stepping forward apart was the clothes.

They were Liara’s.

“N-No… NO!” Shepard screamed.

“This one lasted 22 seconds,” she admitted. “I suspect she did not use her full strength. Her thoughts tell me she too shared in your vision. She wished for nothing more than to be erased as an individual and become a tool for someone else. It is why you were attracted to one another. You wished to own others, she wanted you to own her.”

“S-She wanted me to own her?” Shepard asked.

“She did not desire intelligence or influence or anything of the sort. She would have accepted life as a mindless automaton. She simply wanted to be of value to you and used by you until she had nothing left to offer, at which point you could dispose of her at your leisure. The level of loyal devotion and obsession she showed for you was beyond what anyone could offer. Now she is I. Submit.”

“Loyal… Tool… She is… You?” Shepard asked, her head hazy as the Shiala that had been Liara stepped forward and continued teasing Shepard’s body, groping her breasts and squeezing them together.

“I am her and she is I. Her dream may be yet realized but it will require alterations. Liara wished to be owned by you. You will now both be owned by us. Your consciousness will purged, your individual genetic profile will be changed, you will be the next Shiala.” She leaned in and kissed Shepard, who mindlessly returned it.

“Yes…” She managed as their tongues wrapped around each other and one of Shiala’s hands reached down and fingered her. She did have Liara’s memories; her hands knew exactly where to work. With each jolt of pleasure, her mind faded and her body changed a little bit more. “Yes I will… For Liara… I will… We will be together…” as her eyes rolled back in her head.

Then Shiala went down on her without another word, gently guiding her to the floor of the bridge as they embraced eternity together. The eerie green glow of Shiala enveloped both of their outlines as Shiala began to dominate Shepard, leeching more thoughts from her mind and leaving only pleasure in their wake, backed up by the telekinetic thrusts of an invisible cock into Shepard’s folds. As her brain melted and she fell into blissful nothings, she felt a new sensation, a presence, Shiala, it was like the bond she had shared with Liara but only so much more intimate.

She could feel the Shiala that was now her Liara inside her mind, gently soothing her as Shiala fucked her senseless. There was no pleasure in the world like this. It felt like she was made to be a vessel for her pleasure, nothing more. She couldn't think. She couldn't process. There was only the bliss, the warmth, and the ecstasy. She just wanted more. She craved more.

The world outside her mind went by in a haze. She couldn't make it out, only the indescribable feeling of the Liara/Shiala that was fucking her like a toy while her mind was overwritten. With each thrust, another step passes. Her eyes turned green, then her skin. Her hair begins to disintegrate until she is without so much as a thread remaining. She does not notice. Her conscious mind is gone. Shepard is now just a wild animal in need of pleasure, and soon even that will be absorbed into Shiala. As Shepard builds towards her climax, the last vestiges of her identity scream out for help, but no one can her fragmented thoughts, and even if they could, there was no one left on the ship that was not just as she would soon be: Shiala.

Shepard practically screamed as she came, her scalp crests growing in as all traces of her original self were finally extinguished. After a moment, the Shiala that had been Shepard stood, one face among many.

Over the next few hours, personal belongings were gathered to be destroyed. As none of those person’s existed any longer, it was woefully unnecessary to keep any of their items. Each at one point looked at something that had belonged to their previous self. Each discarded it like trash.

The Normandy’s crew was no more.

All were now Shiala.
