The next room was a quiet, mostly empty laboratory. A few workers were occupied with carrying cardboard boxes of black strips out of a door in the back of the room.
"This is the latest project we've developed in Codename Vacbed," Dr. Morris announced to the group of female soldiers. She gestured to a strip of glossy black rubber sitting on a nearby table, which resembled a belt.
Through the opened back door, Melissa saw workers loading stacks of peculiar black cubes into the back of a truck. Off to the side, a group of Prometheus Company soldiers were standing at attention as they had been in the last two rooms. Strangely, they were not accompanying any prisoners, only a loose pile of orange prison uniforms.
With her latex-gloved hands, Dr. Morris picked up the belt and stretched it a few times. "The realities of military operations necessitate a power generation technology more portable than the Standing Polymer Generator," she said. "When you're camping out in the middle of enemy territory, you may not have access to a nice rubber wall to recharge your devices. This is where the Mobile Plug Doll comes in."
"By wearing this belt, a soldier can be reversibly converted into a fully mobile generator, allowing us to recharge vehicles and devices on the go," Dr. Morris said. "Since we don't have any 'volunteers' at this time, one of you lucky girls will get to demonstrate it for us. Sergeant Ramirez, please strip naked and put on the belt."
Melissa eyed the doctor in surprise. "Er, doc... strip naked? Right here?" Dr. Morris replied, "Yes, sergeant. The polymer will absorb any clothing or small objects on your person, so you'll have to remove your dog tags as well."
Melissa stepped next to Dr. Morris and reluctantly removed her clothing, dropping the pile of fabric on the table. Blushing and strategically blocking her private parts with one hand, she picked up the strip of rubber.
Dr. Morris noticed Melissa's hesitation and reminded the nude soldier, "Don't worry, this is the temporary variant of the polymer. Once we're done with the demonstration, the latex will reform your human body exactly as it was before, and if you've already bonded with a separate Doll-type augmentation, it'll reform you with your augments as well."
Melissa nervously wrapped the glossy latex ribbon around her waist. As she made to tie the belt, the two ends of the latex fused together seamlessly. Suddenly, it constricted tightly around her waist, making Melissa gasp. She stumbled backwards in shock as the latex rapidly expanded, shooting across her skin and enveloping her whole body in cold, tight rubber. She uttered a yelp that was quickly muffled when the latex coated her mouth and face. It covered her eyes, plunging her world into darkness. Every crevice of the woman was filled by the creeping black substance. Soon, Melissa was completely covered with skin-tight latex; not a single curve or muscle was hidden by the tight rubbery coating.
Panicking, Melissa desperately clawed at her face, trying to remove the latex from her skin. At that moment, however, a wave of heat emanated from her crotch throughout her entire body. Melissa's knees buckled as her mind was flooded with pure lust and an erotic fire raged in her loins. Unable to hold back her urges, her hands darted to her vagina and she started to finger herself.
As Melissa masturbated, latex seeped into her body. The line between her skin and the rubber became indistinct as she was converted into black polymer. Melissa moaned in pleasure as the tissues of her body fused together into pure latex. Her mouth, pussy, and asshole dilated and were reshaped into identical circular holes. Her blissful noises were muffled as she stuck her hand into her mouth, now a tight shaft for plugging rather than eating. Melissa relished the feeling of rubbing her fingers against the ribbed shafts of her mouth and vagina. Inside, her body was now a uniform mass of pure rubber. Her glossy black skin felt incredibly sensitive as if her whole body was an erogenous zone.
"As you can see, the sergeant's body has been optimized to generate orgone energy," Dr. Morris said matter-of-factly. "Her libido has been cranked up massively, so forgive Ms. Ramirez for her licentiousness."
"Of course, it simply won't do for a soldier to finger herself in public, so we implemented some tech from Codename Drone's projects to make subjects behave themselves." Dr. Morris turned to Melissa and commanded, "Plugdoll, freeze."
Melissa froze, her hands still jammed in her pussy and mouth. Her lust did not abate, though, and the woman struggled to move - but all she managed was a little twitching.
"Plugdoll, default pose," Dr. Morris barked.
Melissa's body was forced into a perfectly straight standing position with her arms at her sides and her face staring straight ahead. Melissa jerked and strained, but the tight latex only stretched slightly as she wobbled in place.
"Plugdoll, exposure pose."
Melissa felt her limbs force themselves into a new position with the squeaking of latex. Her legs squatted and splayed outwards, and she placed her hands behind her head, exposing her naked body lewdly to Dr. Morris and the group of blushing women. In this position, Melissa's fuckhole mouth and pussy were clearly visible while her identically reshaped asshole gaped from between her buttcheeks.
"In our initial trials, test subjects were embarrassed by their experience as a Mobile Plug Doll, so we decided to implant some mental conditioning to help subjects accept their new forms," Dr. Morris said.
Melissa could feel the soldiers staring at her lewd pose and naked body. Her hardened nipples, her glistening muscles, her mouth and pussy reshaped into perfect holes - every inch of her body was exposed to the world, and she loved it. She loved her new rubberized body, and she instinctively knew that she was no longer human, only a mass of latex shaped like a woman. Melissa knew that her only purpose was to be plugged full of plastic cock, to service those around her as a shiny, artificial plugdoll.
The rubbery plugdoll quivered in desperate need to be filled.
"Sergeant Ramirez is now producing energy, which can be used to power devices or recharge batteries," Dr. Morris continued. "While a Mobile Plug Doll won't make as much power as a Standing Polymer Generator, a plugdoll's main benefit is its mobility."
Dr. Morris produced a collar and leash, which she buckled around Melissa's neck. A squeak of surprise came from the plugdoll's mouth as Dr. Morris tightened the collar.
"Plugdoll, transportation mode," Dr. Morris commanded. Melissa felt the rubber pulling her downwards, and she fell to her hands and knees. Dr. Morris pulled her leash and led her across the lab with Melissa crawling like a dog. Melissa's head and ass were raised as she crawled, keeping her holes exposed for all to see.
"Since Sergeant Ramirez can no longer see, it's best to keep her center of gravity low to minimize the risk of falling and dislodging anything plugged into her," Dr. Morris told the soldiers.
Dr. Morris and her plugdoll, accompanied by the small group of female soldiers, walked to a rectangular machine. It looked a bit like the vice from earlier, but it was clearly designed to compress something into a cube. It was powered by a Polymer Battery Complex 6-pack, which occasionally twitched as it released its energy.
"One Mobile Plug Doll is sufficient for everyday uses, but if you need to charge a large machine like a car or truck, the multiple plugdolls required can take up a lot of space. That's why we created a simple device to compress plugdolls into stackable shapes."
Dr. Morris easily picked up Melissa, whose rubbery body weighed much less than when she was a human. She placed Melissa in the machine, still on her hands and knees, and closed the lid. Low mechanical whirring came from the machine as it started to press Melissa's latex body into a more compact form.
Melissa felt the cold metal walls squeeze her body. The inexplicable sensation of her latex skin being squished and fused together by the pressure... it felt like every pleasure sensor in her body was firing all at once. The feeling of being compressed made her orgasm - not once, not twice, but constantly as her legs fused into her ass and her face was squished into her neck. Soon, nothing was left of Melissa but a featureless black cube of rubber. The only remnants of the former woman were one hole in the front of the cube and two in the back: what were once her mouth, pussy, and asshole.
With a hiss, the machine opened, and Dr. Morris picked up the cube by its holes, making the cube shiver in pleasure. Dr. Morris placed the shiny black cube on the table. It was small, about a foot long in all directions. A faint, muffled whimper could be heard as it quivered with need.
"This plugbox can now be efficiently stacked with other plugboxes for mass power generation on-the-go," Dr. Morris told her tour group.
"The combat potential is enormous. If your Humvee runs out of juice in the middle of nowhere, all you have to do is put on a belt and plug yourself into your truck for a few hours, and you can drive out with no fuss," Dr. Morris said. "And for a submarine or other stealth vehicle, a few plugboxes serve as lightweight, replaceable power forever - if one of the permanent plugboxes is molded out of shape or goes missing, a crew member can step in as its temporary replacement."
Dr. Morris bent over and unplugged the 6-pack from the compressor. "The sergeant has probably been waiting for this ever since her conversion," she remarked. She shoved the battery's penis into Melissa's mouth hole.
Instantly, fireworks went off in Melissa's lust-addled mind. She eagerly sucked the latex cock, the ridges in her former mouth milking and squeezing the rubbery rod. Orgasm after orgasm racked her body, and she could feel the energy flowing from her to the battery as if she was cumming from her own cock. Melissa's brain melted in latex ecstasy as she fulfilled her purpose. She came over and over again as her plugbox body writhed and squirmed on the table, the mind inside lost to pure, utter bliss.
