The next couple of hours were familiar in their utter lack of sleep. Over the past weeks, Yvonne had grown accustomed to being unable to rest - she was lucky to get even an hour or two of sleep at night, plus whatever five-minute naps she could sneak in throughout the day. The base commander had been working the science team to the bone, and with good reason - they were, after all, the best and only chance that humanity had to avoid extinction by assimilation. She had told herself over and over that this work was worth it, that the continuity of the species would prove that the exhaustion and endless work had been essential, but after a few weeks of this hell, she was nearing her breaking point. She needed relief, she needed... she needed to just feel good for once.
Even if that meant doing something stupid. There was something she'd considered ever since starting this program. A last resort if they ran out of test subjects. The commander would never allow it, of course... but... Yvonne bit her lip. The futas were truly relentless, observations showing that they didn't need to sleep at any point, barely even needing to eat either thanks to some sort of ludicriously effecient form of what she guessed was photosynthesis. They had already rigged up plenty of special lights to replicate this effect for sustaining test subjects, making it a non-issue. No need to sleep or ever even stop their work... not to mention how much physical pleasure they always seemed to be in... and if the alterations had worked on the sample, then surely... surely the private's own secretions...
An involuntary gasp at the thought cemented this idiotic course of action in her mind.
It wasn't difficult, thankfully, for Yvonne to get down to the containment chamber. A lab coat and shoes thrown on over her naked body, and nbodoy really questioned her, the guards allowing her to proceed through various secure sections. She didn't really worry about trying to disable cameras - it wasn't like Yvonne would be able to hide this anyway. No, all that mattered was getting down to the lab, getting past the guard, and being allowed to enter the cell alone, the door locking behind her. Inside, she let out a sigh of admiration at seeing Teresa's nude form, her shiny sapphire skin, that giant member that seemed to grow rigid just from the doctor entering the room.
"Doc? What's..." She trailed off as the doctor abandoned all pretense by kicking off her heels and dropping her lab coat away, revealing her utter lack of clothing underneath. Hungry bedroom eyes locked onto Teresa as she approached, her bare chest bouncing just slightly and her sex already soaking wet. The private's rod quickly became fully hardened as she stood up, momentarily entranced by what was happening. "Doc... are... are you...?"
Yvonne smiled as she stepped right up to the private, pressing her chest against that enormous bosom and letting the blue shaft slip between her inner thighs. "Teresa... I... I need you." Her lips quivered slightly. "This thing you are... this, this freakish, gorgeous thing... I... I want... I need to be one..." She leaned forward to kiss the young hybrid's plump lips. "You're like this because of me... it's... it's only fair..."
The new queen needed no further invitation. With a grin she pulled her hips back then thrust them forward, jamming her dripping shaft into the scientit's aching slit. Soldiers were scrambling outside as the beautiful doctor cried in delight, but they wouldn't dare enter. None would have the courage to intervene as the the fluid in the hybrid's massive, dangling testes began to pump into the woman she adored, the royal nature of her own physiology ensuring that the assimilation would be even more rapid than any drone's conversion. She deserved that much, as so willing a recipient of this gift - in fact, the pleased voice of the Queen Mother filled her mind, alerting her that this woman was to be give a very special treatment indeed.
She would not gain a latex skin nor her throbbing, meaty cock immediately - not quite yet. But within her body, the latex would spread, bonding with her organs and especially with her spine and brain, winding around and becoming enmeshed with her central nervous system. As soon as the latex touched her mind, the psychic floodgate opened, allowing Yvonne into the hive-mind and bombarding her brain with imagery of the glory of the hybrids, of the pleasure that awaited her entire speices when the Earth was converted. She resisted for a fraction of a second before her shoulders relaxed, eyes taking on a golden coloration that matched the gold latex her body would one day be covered in.
Yet for the moment, there was an understanding shared wordlessly between the two women. Yvoenne had to keep up appearances, let them think the project was a success - and when the humans threw all their eggs into this basket, they would strike, converting all resistance right where it was most vulnerable. Yvoenne grinned as the plan was understood, her heart beating faster and faster as every spurt of assimilating fluid into her body forced another orgasm to rock it. The planet's greatest mind was fully in their cause, her eyes opened to the wonders of the futas, her heart filled with adoration for the sweet and corageous girl who'd become Earth's new queen. She was in love, achingly so, with this gorgeous blue woman - and soon the entire planet would get to share in that love.
