Today, he couldn't manage to hold back. A fresh batch, right out of the tubes, giggling and chatting and smiling cutely as they pranced into his classroom.

He was supposed to give them the basics on how the Instaprinters worked, the generic templates they could pick from for necessities. Letting them feed and dress themselves as needed left a few hands free for other work.

No, there was plenty of time for that later.

"Alright, ladies. Katya, please come to the front of the class. Everyone else, take your seats and assume the Ready position."

She didn't have a name before he pulled one out of the air, but Katya eagerly pranced to the front of the class all the same. Twenty three nearly identical blonde bimbos settled into their seats.

Any one of them could have been Katya, but somehow the herd had singled out a lucky winner without a moment's hesitation.

They'd learn a lot about their innate instinctual behaviors in the next few hours.

He glanced across the room. Twenty three out of twenty four seats filled, every jiggly girl watching eagerly, arms thrust down behind their seats, feet spread.

"Good girls!" he called, and tapped a button on his desk. With a loud buzz, steel bands snapped from the chair legs and locked their ankles down, reached out from the back of the seat and hauled their wrists down a little more sharply.

"Everyone comfy? Good, we can continue. Katya, be a dear and strip off your uniform." She was quick, eager, efficient. He barely had time to tap a finger on his desk before her skirt, top and stockings were neatly folded in her hands, tall shoes stacked on top. "Set them here, then bend over my desk, please. I'll need to make quite a few spares for this lesson."

He tapped a few buttons on the Instaprinter console, listening as the phone booth sized white box hummed to life. With a soft *ping* the door opened, and he snatched the two sixpacks of HydraPlenish from the floor, setting them on the desk beside Katya. She let out a happy squeal when his hand slapped her jiggly ass, but the whole class gasped and leaned forward as he unceremoniously hauled the buzzing pacifier from her cunt, and just as brusquely jammed his cock into her dripping snatch. Hands on her hips, he closed his eyes, took a deep breath, and found his center.

He willed himself to do the exact opposite of what the staff usually wanted. He needed to get off as fast and as easily as he could.

Three quick strokes in her cunt were enough before he erupted. Katya let out a confused little noise at the quick treatment, but then the terrified screams as her belly suddenly churned and swelled gave her something new to worry about.

He pulled out with a squelch as the new livestock crowned and erupted from Katya, shifting to the side as the squalling infant erupted through childhood and adolescence as she tumbled from Katya's cunt, tumbling head over heels to land flat on her back on the cold tiles, spread-eagled and confused.

She was more pinkish than the vat-grown livestock, but her skin was already mottled around her face, shoulders, arms and the tops of her wobbly breasts with brown freckles. Her teats and cunt were brown, not pink like the class. And her hair was an unruly mop of copper-orange curls, not the sleek blonde of the base stock.

"Hello, Mimi. Be a sweetie and step into the box there," he said, gesturing to the InstaPrinter. "When it's done, you should be just in time to help your next sister up and into the box, too. Can you do that for me?"

"Uh...? Oh! Oh, yeth, thir! Of courthe!" Mimi snorted a bit with her giggle and pranced into the printer booth.

Katya was sobbing in confusion on the desk. "Muh.. Mister...?"

He fondled her stretched, abused cunt. No time to linger. He needed a lot of bodies. "Katya, sweetie, could you clench for me...?" She whimpered and nodded, and her cunt was acceptably snug again when he shoved his cock in her cunt again.

Mimi was right in place when he pulled back from Katya again, a nurse's hat on her head and a too-short dress that couldn't begin to zip over her wobbly tits wrapped around her waist, her heels clicking on the tiles as she stepped up to catch the second fresh ginger that Katya ejected like a meat pitching machine. She giggled and cradled her new sister until she could wobble on her own two feet, then herded her off to the booth. He smiled, then slapped Katya's gaping cunt sharply, tearing the first bottle of HydraPlenish from the packs and chugging it down as he rutted some more.

It took nearly three quarters of an hour before he had enough to work with. Nearly fourty of the curly-headed gingers, giggling and snorting, lisping around buck front teeth. The InstaPrinter had practically exhausted its collection of sexy costumes, not a single duplicate in the new herd.

Poor Katya was barely a shell of herself. She had giving up shrieking and screaming long ago, her anguished sobs had broken to atonal moaning around the thirtieth new girl or so. She didn't even twitch as he tried to shove her inverted uterus back up into her gawping cunt, but it just wouldn't stay inside her this time, dangling loose under the five inches of prolapsed anus.

"Thank you, Katya. That should be enough." He touched a button on his desk to set up the next stage of the demo, then rummaged in a drawer.

A collapsed loop of razor wire. Perfect.

"It's time for you to rest, Katya," he said, slipping the coil of flat, etched ribbon steel around her neck. Katya's shattered mind managed to bring her wandering eyes back to his, and she smiled vaguely.

Then he gave the ring at the end of the cable a sharp yank, and the coil of razorwire shredded the meat of her neck in a gory spray, yanking her head off and sending it spinning to the floor.

He didn't pay the meat on his desk much attention as the severed head spun on the floor. He furrowed his brow and tried to remember its name.

He just couldn't recall. Oh, well.
