Of course it works

When she came into existence, Tiriana knew exactly where and who she was.

She was lying on the deck around the pool in Riley's mansion.

She was the fourth body in the hivemind that had started with Toby and Tab, and then added Tam.

She knew she was seven feet tall, with a 36P bust and a dick that would be eighteen inches hard, to go with the fifty-five-inch butt that was making her arch her back, not that it felt uncomfortable.

And, most excitingly, she could feel the roiling core of boundless, vital, pure energy in her body that marked her out, along with, rather more visibly, her pointed ears, as an elf.

"It worked," she said quietly to herself, and knew that three voices in a room not too far from where she was gracefully rising to her feet had said the same thing. She couldn't find any way to not have one of her bodies, though, so it hadn't been her true best-case scenario, but she also didn't feel tired or hungry as the fuel she was constantly generating drained out to power all four of her bodies.

"What worked?" she heard Ronnie say through her shared mind, the sound hitting her six other ears from slightly different directions. She'd grown used to that pretty quickly, though. Her sharper hearing even picked up the sound itself through the walls, albeit very faintly.

"Give me a moment," her common mind directed Tab to say. "I'm next to the pool this time."

Tiri padded out the door, her feet making no sound as they struck the floor, her body leaving no air moving as it passed. Elvish superiority indeed.

Beth was the first one to turn her head as the handle turned and the door opened, but her patients--and lovers--weren't too far behind.

Standing in the doorway, closing it behind her, was a vision of supreme beauty.

On the surface she looked little different from Tam. The facial features were almost identical, the auburn hair falling in the same waves. The breasts were every bit as massive, the muscles just as defined, the dick just as large, the body just as tall. But something about her just made it all work together in a way Toby, Tab and Tam did not. This new body walked over to join herself, then Toby and Tab swept her hair back.

Beth nodded, and noted the gasps half of surprise and half of pleasure from the other two randy university students.

"You made yourself an elf," the doctor said, stating the obvious.

"An elven body," the new figure said. "I'm still mostly human."

Beth felt herself getting aroused simply from hearing the perfectly melodious voice, as if the words carried some mystical quality with them that bypassed ordinary mental processing and hit her pleasure centres directly.

"Have you chosen a name for yourself?" Ronnie asked. "Though it'll be harder to hide what you are when you get dicks hard and pussies wet just by talking."

"I'd already decided what my name would be when I created myself," the elf said. "I am Tiriana, and it is a pleasure to meet all of you. Again."

"Tiri for short," Tam put in.

"I hope you won't mind wearing the same stuff as your other bodies, once I get it made," Riley said. "Don't exactly have anything suitable for an elf, whatever fantasy setting you drew from."

"I'm still me," Toby said.

"More importantly," Beth said, "how are you feeling? It doesn't seem like there were any anomalies, but given that you just willed a body into existence that's straight out of pure fiction, I can't imagine that that was just completely painless."

"I realised that if I'm going to be making myself more bodies, it really wouldn't do to be needing to eat so much after each one," Tab said.

"So when I made me, I envisioned an elf with eternal youth and endless energy," Tiri chimed. "And I think when I make myself a body now, it should just draw on the bottomless well in me. I might not even need to eat at all any more." For all that her passage left no traces in the air, her chuckle felt like a breeze wafting past everyone's most sensitive parts.

"So now you can just poof new bodies into existence for yourself," Riley said.

"As long as I feel incomplete without them," Tam clarified. "As I said, I don't think I could make another plain human futa, since I'm already that."

"Before you go making any more bodies," Beth suggested, "I'd like to run another medical workup on all four of yours. Who knows what I'll find with you, Tiri, but I figure I have to check, at least."

The elf nodded. "That's fine. Honestly, I don't know what you'll find with me, either."

After drawing blood--"Literal blue blood," Riley said, rolling her eyes when Beth drew Tiri's--taking skin samples, as well as sexual fluids, Toby, Tab and Tam's results came back normal in short order, while Tiri's made the machines go haywire.

"Well," Beth said, "the one thing I think can say for certain is that whatever you've got in there, Tiri, it's different enough from anything found on Earth that these can't even classify you as another plant or animal."

Tam sat down on Toby's lap, easing the hard dick into her butt, letting out a light moan as both her prostate and G-spot were stimulated. "Let's start with the basics. Am I carbon-based, at least?"

"Yes, more or less. I think," Beth said. "I'm not any sort of expert in spectrochemical analysis, but from what little I do know and what the computers tell me, it's definitely primarily carbon-based organic compounds, after water, of course, but some of the chemical bonds simply defy explanation. They just shouldn't occur in nature."

"I don't occur in nature," Tiri pointed out. "I generate energy of some sort completely from nothing. Is it any wonder that chemistry just kinda goes out the window where my body is concerned?"

"Doesn't mean I have to like it," Beth retorted. "I can't treat you properly if I can't make sense of your biochemistry in the first place!"

"I envisioned my new body as being pretty much immune to disease and healing really quickly," Tab said. "There probably won't be that much to do at all."

"Plus I have a kill switch on my fertility," Tam added, grinding her massive butt against Toby, her cock twitching with spurts of precum. "No need to worry about interspecies impregnation when I can simply blank all my haploid cells."

"If I even have haploid cells, that is," Toby added.

"In short," Tiri concluded, "I doubt it's anything to worry about, but I was planning on making myself a few more bodies before we dove into the debauchery again anyway."

Riley, Ronnie and Beth didn't take objection to the assumption that of course they were going to go right back to fucking for the day; Tiri's presence alone made all of them too aroused to consider otherwise.

"What bodies were you thinking of making?" Ronnie asked.

"Well," Toby said, "this is as if, by divine providence, my wishes have come true, isn't it?"

Tab impaled herself on Tiri's dick even as the elf took Tam's in her butt, the four of them locked in coitus as they focused on adding yet more beings to their growing consciousness.
