Chel/Zeni are mine

'Tick-tock,' said the clock with a fox. It hung on a pale wall which helped enclose a disheveled workspace. The floor was strewn with papers, each one scrawled with chicken scratch. For every stroke of genius put to pen, like a hitherto unknown protein, there were countless failed starts, like that one gaming dildo. But that was the nature of the beast! Science was no absolute, it was a process constantly revealing itself through the bubbles in those beakers and vials, the creaks of Chel's spinny chair.

Yes, that was enlightening her at this very moment: she really needed to oil that thing.

"Alright," the feline's brows furrowed as she turned away from her screen. She stood, and the blue glow of her monitor lent her a dramatic aura. Fingers were in her lab coat's pockets, and her golden gaze looked pensive. Chel, real name C4E1, had been -thinking-. Which didn't bode well for anyone.

Her assistant, Z3N1, had rushed to the aperture from elsewhere. She made sure to only let her head poke through, lest she hastily subject herself to another workplace hazard. I mean, at least she wore a helmet over her head, sure it was really just a black glass that was only good for displaying a simplified facial expression. But it was waterproof.

Z3N1 (let's just call her Zenny) asked: "What happened, ma'am? Did you ever get to finish your interactive text game?"

Chel pushed the frame of her glasses higher up her nose. "No. I'm overscoped and overbudget."

"But it's a text game--"

"Anyway," Chel gestured openly, "That's not what I sent that Psionic signal for. I've finished all the preparations for my latest and greatest Synthesis... A new protein that will--"

"Make your dick bigger?"

Chel tried to decipher Zenny's expression, which was currently a scrunched-up tiny set of lines that looked more like an error code. The cat asked, "Pardon?"

Zenny's face then returned to relatively normal, by the standards of a Tamagotchi pet, "The penis one, ma'am."

Chel snapped her fingers, "Yeah! I call it P3N15-69. Not because it's my 69th iteration, I just like that number. How'd you know?"

Z3N1 stepped fully into the room, having to tackle it an an awkward angle due to her jet wings. Her fur was powder blue and she looked vaguely canine, though she wore pink plating over her thighs and bust. Accent lines glowed a neon blue, and her rotors occasionally spun when she was too excited. Which was most of the time.

Her fingers steepled together, "Oh, you know. It's just that due to the nature of the temporal abnormality, we've been stuck in a single room surrounded by a vaguely defined liminal space for the better part of forever. And I can't help but hear you rave about the PENIS PROTEIN whenever I try to get some sleep. But otherwise, I guess it was just a stroke of genius."

Chel beamed her a toothy grin, "See, that's why you're my Proto!"

Zenny muttered, "You must have been drinking That Protein That Drains Your Brains Stat again."

This was entirely ignored by the cat, who segued, "And that's why you're going to drink it."

Chel brandished two vials full of glowy pinkish-purple. One was for herself, the other was handed over to her assistant, who scanned it over quizzically.

Z3N1's face bounced around on its screen like some 90's screensaver, "What exactly is the chemical composition of this mixture? My Scan is failing to yield any useful insights."

The feline counted off the ingredients on her fingers, "Let's see... Sugar, water, pink, purple... And the essence of penis. Why? Are you on that Synthetic fad diet again? Hehehe."

"No--" Zenny made a side-remark, "I mean, eating Organic isn't good for you, 100% of people that consume dihydrogen monoxide eventually die, for example. But I was just wondering--well, you probably don't remember, given the nature of the temporality. But for the last 939 iterations, this protein failed to affect me. So I wanted to know what you've done differently this time, ma'am."

"--I flipped the P."

Z3N1's gaze narrowed, "You did what?"

Chel tried her best to explain, "If you look carefully at the composition of the word 'protein', there's a p. I simply flipped it to 'brotein'. Then I inverted 'bro' to 'sis', then moved 'e' to the end, to derive 'sistine'. I added 'chapel' but wasn't sure where I was going with that. So I reverted to 'sistein', derived 'cistein', inverted that, and now I have a transtein that will transmute anyone's genitalia. Quite simple, really."

"That doesn't make sense."

Chel snarked, "Your dick won't make sense once it slaps you upside the face!"

Z3N1 momentarily paused to compute, then tipped back the vial to drink the contents. Unfortunately, she forgot she was wearing a helmet, so droplets streaked down the glass and nothing more!

"Ugh," Chel groaned, "Take the helmet off, first."

Zenny blinked. "I can do that...?"

She turned away and lifted the helmet. Now because this work is intended for general adult audiences and there must be considerations for the sake of those faint of heart, a description of a Proto's actual face will be omitted. But after imbibing the rest of the contents, Zenny snapped her helmet back on and once again regarded Chel, who had also finished quaffing hers down.

"Ma'am, am I supposed to feel any different?"

Chel held her hands at her hips. Her red shoe tapped the ground, "Give it a few seconds."

Tick-tock, tick-tock, BOOM!

Z3N1 was gripped by panic. Her crotch-plate was suddenly straining, and the screws which held it on were starting to strip! The compression really ached and with it came this searing hotness between her legs. There must have been some shorted wire in her abdomen because fizzliness coursed through her extremities. All of her sensors went haywire as the OVERSTIM protocol activated!

"Wahhhh!?" Z3N1 gasped, "My hull is being breached!?"

With a thought, Zenny released the latches. With a hiss, her breastplate fell off her body in two halves, letting her tits spill free! She looked down and felt initially relieved--her boobs didn't catch fire like that one time, her body was just really, really hot and bothered. But then she saw something stick out WAY further than her tits, the moment her crotch-plate clinked against the ground.

"What the CIRCUITS is that!?"

"Language, Zenny!" Chel really couldn't tolerate any swearing, "That's your new dick. It's not that different from your holo-dick, just a bit bigger, meatier, more corporal, that sorta thing."

Z3N1 looked like she was going to faint. That absurdly large THING jut out over a foot past her nipples, and it was FLACCID. The girth transitioned from powder-blue at the base to a deep, throbbing sapphire at the bell-end. The entire length was incredibly shiny, hard, and veiny. The meat of the middle was thickest, but even the crown was about the size of a door-knob. The whole thing was as long as her arm, while SOFT.

"Ma'am, must it be so, erm, VASCULAR?"

Chel snorted, "Oh, grow a pair."

And that she did. Zenny felt two distinct spheres somewhere in her belly, as they flared with heat. They descended her abdomen and as they did, they seemed to grow larger and larger. Colliding with several internal organs in their haste to escape her insides, making Z3N1 feel a little queasy.

By the time they reached her crotch, they were big enough to be seen. And they spent some time there, trying to barge past another and squeeze through the narrow between her thighs. The whole ordeal made Zenny dizzy as she lowered a claw and poked one, feeling a tingle. It was so turgid and sloshy...!

Wait--where were they going?

Shhhlorp!

One orb won out and pushed itself past the other, descending from her crotch in a sack of flesh. Skin stretched and fur spread, as a wobbling -testicle- crowded into the gap between her thighs, forcing Zenny to spread her stance. The other one tumbled into the sack, piling atop the other one and making her feel funny as her balls collided, so full of heft as they were. They were literally the size of melons and swung pendulously around her knees, getting settled into place. Loosely attached to the beast of a dick's base, Z3N1 couldn't help but notice they were as saggy as her dick was veiny.

Her digitized face scrunched, her mouth all squiggly, "I'm n-not sure how I feel about this one..."

Chel motioned, "Maybe you'll change your mind once you actually feel it. I can personally attest to good results."

Z3N1 hesitantly held her hand over her obscene new cock, but first glanced towards Chel. She was quite shocked to see the cat's own endowment, though. Her dick had burst clean through her clothes and really only left scraps behind. That huge dick was nearly black at the end, as it flowed from her dark blue fur. A little shorter than Z3N1's length despite jutting out fully hard, the dick sure had an interesting crown of barbs to make up for it, though.

What really dropped Zenny's glass jaw, though, was Chel's ballsack. The orbs were TWICE the size of her own and churned violently. Thrumming visibly and even intimidating in their size and weight. Oh! If Zenny hadn't literally grown a massive pair of nuts herself, she would've flown away in fright already.

Zenny remarked, "Erm, interesting choice of proportions, ma'am..."

Chel winked, "Don't worry. I know you're afraid of sharp objects, so I can assure you, the barbs are just for show. No, there's a good reason I've designed a BIGGER DICK for you, my lovely little Xenodrone. You're going to pummel me until your servos give out. There's going to be so much jackhammering, and wrecking balls swinging around, it'll be a construction site. Also--"

"Okay, okay, I get it," Zenny huffed, totally flustered.

The cat promptly spun around, and as cats are known to do, knocked all the stuff off of the table. Screw science, now it was time to SCREW for SCIENCE!

Her tail hiked up and presented her derriere, "Well? Run those tests!"
