"Avatar," she said in a new voice. Feminine, resonant, and wholly inhuman. "Yes. I have become the Avatar of what is to come." She stood, the dildo sliding easily from her now accommodating ass. If she bothered to look back, she would have seen the Obelisk was slate black now. Just a dead rock. But she already knew that. It had served its purpose. Now she had a new vessel.

Green, potent seed continued to drool from her massive prick, leaving a glowing trail behind her as she strolled from the room. All that was left of her outfit was a partially cum-drizzled labcoat. No reason for even that amount of cover, she decided, and let the garment slide to the floor. There was a crew of an entire ship to corrupt, one after another, until all were One with the Avatar. She'd start with the Captain, the one who didn't appreciate what power lay beneath their feet. Then, she figured, she would work her way through ship, converting the crew, each spreading their own seed when they returned to their home colonies. Planet after planet would fall until the entire human race was One. The part of her that was still Doctor Singer reasoned that this may have been why the species on the planet below had died out. But that didn't matter. All that mattered was bringing all into the fold. The Avatar smiled.
