Chronivac Version 4.0

This story is based on the Chronivac Diaries located at http://www.geocities.com/uniclock/stories.html. CHRONIVAC is copyright 1999 by Mark Kwestin.

TransDem Labs has just completed its newest version of the Chronivac Machine. Thanks to advances in technology the user can now use their Personal Computer to make changes to themselves or others.

Chronivac version 4.0 includes a CD-ROM that contains the altering software, a portable emitter, and a USB connection to a PC.

The portable emitter can be programmed with up to ten customizable changes that can be processed without the use of a PC (although higher detailed altering can only be made with the help of a computer). The portable emitter also contains a revert button to undo any changes made.

Connected to a computer the Chronivac program can now change almost anything imaginable both physically and mentally. The only main limitation is that only living things can be changed into something else living (excluding any type of plant). So a person can be altered into any type of human or animal.

When connected via PC you have the ability to scan any possible transformee to upload their personal information to make alterations easier.

Here is a list of major alterations that can be made: Age, Species, Gender, Nationality, Height, Weight, Eye Color, Hair Color, Body Sizes, Hairiness, and almost anything you can think of. Many mental changes can also be made; major mental changes include: Age, Species, Sexual Orientation, Perception of Reality (EX: transformee either knows that he has been changed or thinks that he has always been the what he is), and much more. Most alterations use a slider bar to control the change.

Alteration can be made through the software by selecting the feature to be changed from a list or by searching through the entire list at once.

Chronivac version 4.0 does not offer a preview of changes being made but will apply the changes once the save button has been pressed. If the save button is not pressed again within one hour of the first save the change will be reverted for safety reasons.

The Chronivac emitter will transform whatever being is in front of it and has a maximum distance of 20 feet.

Now TransDem Labs is looking for a possible tester for their new software and will send the program to a random person with no instructions on how to use it.

Who Does It Get Sent To?

*Two female roommates

Nikki's new anatomy

Nikki, always the skeptic of the pair, snorted dismissively at Jessica's excitement about the strange computer program, "It sounds like some weird joke to me. It'll probably fill your computer with like a hundred viruses and pieces of malware. You'll be getting ads free Viagra and natural herbal supplements to grow your dick or grow your tits for the rest of your life if you use the stupid thing."

"Well, I'm going to try it anyway," Jessica shrugged, "You've been bugging me to get a new computer anyway with the way this one's been acting up lately. Frying it with a virus would be just the excuse I need."

"Have it your way," Nikki laughed and headed to the kitchen to fix herself a snack.

It was just like Jessica to want to try some silly thing on a whim, not caring if it would work or not, or what the consequences would be. Of course she had a lot of fun with all her crazy ideas, so maybe it wasn't that bad a way of going about things. Still, Nikki thought it was silly.

Not sure of what she wanted to eat she wandered aimlessly around the kitchen, opening the fridge, closing it with a frown when she saw that it was pretty much empty. Unless there was something in the cabinets the pair of them were going to have to do some serious grocery shopping.

She checked the cabinets over the counter first and they were pretty full, albeit with cereal and junk food that she wasn't in the mood for. That was the problem with sharing a house with a friend who had a wildly different way of organizing things, not to mention a different idea of what counted as a good snack. There was never any way to be sure what they had or where it was in the kitchen.

Shifting her weight as she rummaged through the cabinets, she felt her panties pressing against her clit in an way that was not all that unpleasant. In fact she kept looking long after she normally would have given up and moved on, just because of how good the pressure against her clit was. It was strange that she had never noticed how sensitive it was before, but that might have been because this was a new pair of panties. Perhaps it was because they were tighter, pressing harder against her clit than any of the old pairs, or maybe the fabric they were made of was softer and silkier. Either way it felt good.

"How you doing in there?" Jessica asked with a laugh.

"Fine," Nikki sighed, "But we're going to need to go shopping soon."

She squatted down to look in the bottom cabinets and let out a small hiss. The movement cause her panties to press so hard against her clit and pussy that it was almost painful.

"And not just for food," Nikki said as she quickly stood up, trying to adjust her panties. For some reason they felt unusually tight today, especially in the crotc, "I might need to get a few other things.

"Really? Like what?" Jessica asked, sounding a little too innocent and maybe a little surprised.

Nikki rolled her eyes, used to putting up with teasing form her housemate, "You know exactly what I mean."

Her friend giggled, "You're kidding!"

"No, I'm not," Nikki reached into her pants and tried to adjust her panties, the pressure having gone from pleasant to uncomfortable, but no matter how she tired, she just couldn't get them to sit right over her clit, "These stupid panties must have shrunk in the wash."

Forgetting all about getting a snack, she limped out of the kitchen, the pressure getting worse with every step she took.

Jessica was watching her with a sly smile as she hobbled past.

Nikki rolled her eyes at her friend's intent gaze and expression, "If you get your magic computer program working let me know. I'll be in my room changing."

"Sure..." she said slowly, "You sure will."

"What's that supposed to mean?" Nikki stopped, crossing her arms over her chest.

"Oh, nothing," Jessica said airily and went back to staring at the computer monitor.

Discomfort getting the better of her, Nikki hobbled into her room, unzipping the fly of her jeans as she went. Even that little bit helped and as soon as she was in her room she flopped down on the bed and flung off her jeans and panties, letting out a sigh of relief as her clit was released. Rolling to her side she looked down at herself, her clit sticking out above her neatly shaven pussy. Everything seemed okay down there. Just to be sure she gave it a gentle rub. Yeah, everything felt okay, better than okay really. She rubbed a little harder, giving it a careful squeeze for good measure.

Well, it wasn't like she had anything better to do anyway. Moving her fingers a little lower she dipped them into her pussy for lubrication, then went back to working her clit, smiling as it perked up, its little pink head peeking up from above her folds. She ran a finger wet with pussy juice along the head of her clit and let out a soft moan of pleasure. Having such a big clit made finding comfortable panties difficult, but the pleasure it gave her more than made up for that small hardship.

Taking its inch length between two fingers and her thumb she rubbed it until it was fully engorged to twice its normal length. Stopping for a moment she admired the two inch long nub, watching as it twitched slightly with each beat of her heart. With a smile she ran the tip of her finger along the crown of the head of her clit, its most sensitive part.

While she was at it she figured that she might as well go all out. Sitting up she opened the top drawer of her nightstand and pulled out her vibrator. To warm it up she put it in her mouth and sucked on it for a moment, not wanting to put it into her pussy cold and risk ruining her mood, not to mention, since she didn't have a boyfriend yet she liked to pretend that it was a real cock that she was sucking on. Once it was satisfactorily warmed by her mouth she turned it on and gently eased it into her pussy, savoring the way it parted her folds until she had it in as far as it would go, which was only half its length. Despite having such a big clit she had a fairly shallow pussy, but she was willing to take the good with the bad.

She thrust it in and out for a bit, but as good as the vibrations made her pussy feel, they weren't really going to get her anywhere. Slowly she pulled it out and ran in along the underside of her clit, the vibrations sending tingles of pleasure through her whole body. Oh yeah, that was just the trick. She ran the vibrator up and down the three inch length of her clit then held it there for a moment, keeping the full length of the vibrator pressed against her throbbing clit.

Not ready to cum just yet she released her clit and dipped the toy back into her pussy, sliding it back and forth between her moist folds. With her other hand she gently grasped her clit, gently sliding up and down its length.

Putting her toy down on the bed she reached back into the top drawer of her night stand and took out a bottle of lube to really get things going. Pouring some into her hand she lubed up the full length of her clit and thrust into her hand, in the process knocking her toy off of the bed.

She kept rubbing herself for a bit longer, feeling the pleasurable pressure building in her stomach until she was on the edge of climax.

A knock on the door caused her to freeze.

"You okay in there?" Jessica asked, mercifully keeping the door closed.

"Yeah," Nikki said breathlessly, "Just a little busy is all, if you know what I mean."

"Sorry," Jessica giggled.

Nikki listened to the sound of her friend's footsteps moving away down the hall and let out a sigh of relief. The sudden fright had caused her to go soft, but she could fix that easily. Reaching over the side of the bed to the floor she retrieved her toy.

A little squirt of lube and the pocket pussy was ready to go. For good measure she rubbed her cock a bit more, making sure that it was fully hard again before plunging it into the pocket pussy and thrusting. Her balls and breasts bounced with her efforts until, with a tensing in her balls, she came.

Flopping back down on the bed she let out a contented sigh and flopped back down on the bed.

A moment later there was another knock on the door, "Are you done yet?"

"Just," Nikki panted, "Just give me a few to clean up and get dressed. Is that too much to ask?"

Of course, Jessica being Jessica that was indeed too much to ask and her friend opened the door without even giving Nikki the time to cover herself.

"Really," Nikki slid her still half hard cock out of the pocket pussy with a moist sucking noise, lube and cum dripping down her balls, "And stop staring."

Jessica blushed and looked away.

"Jessica," Nikki continued, getting up and grabbing some tissues to gently blot her cock dry, "Staring at me like that, it's like you're gay or something."

"Hey," Jessica countered, "You're the one with a cock and balls."

Nikki ignored her friend's comment and took her time cleaning herself, careful not to leave any lube stuck under her foreskin where it would cause a most annoying itch if left to dry there. Despite Jessica's teasing, she saw nothing wrong with her anatomy. Yeah, she was more of a grower than a shower, just shy of four inches when soft, but once she was hard she was a respectable six and a half inches, bigger than most guys form what she'd heard.

Not willing to let the matter rest, Jessica continued, "And you were using a pocket pussy. You know, a pussy, like girls have."

Against her better judgment Nikki took the bait, "Yeah, I use a pocket pussy, but it's only because the texture feels so good on my cock, much better than just using my hands. Unlike you I don't have a boyfriend so I have to make due with what I can."

Jessica smiled another one of her sly smiles, "And if you had a boyfriend what would the two of you do?"

"Oh, probably suck each other off for starters," she smiled dreamily, "Maybe try anal."

"You or him?" Jessica said quickly.

"Oh, I'm not sure how I'd feel about a guy doing that to me, but if he let me do it to him I guess I'd have to -" she stopped when she realized the direction the conversation was going, "You're such a pervert, you know?"

Jessica started to say something more, but Nikki cut her off, "And speaking for perverts, did that program fill your computer with viruses or horrible porn?"

"Neither," Jessica beamed, "It works."

"Oh, really," Nikki rolled her eyes as she picked up her boxers and pulled them on, adjusting her balls as she did, "And what did you change?"

"Oh, not much," Jessica continued to smile, "I just made it so you had a cock and balls instead of a pussy and changed it so reality would adjust and you wouldn't think there was anything strange about it."

"You're so immature," Nikki tried not to get mad at her friend, "Teasing me like that. I'd know if there was anything different about me and you know I've always been like this."

"You want me to prove it?" Jessica asked, eyes gleaming.

"Sure," Nikki decided to go along, just to see where her friend was going to take things, "If it really can change reality make it do what I'm sure all the spam emails you'll be getting are going to promise. Give me a bigger cock!"

She burst into giggles after that, unable to keep a straight face in the absurdity of it all.

"Sure," Jessica said, laughing just as hard, "Bigger balls too?"

"Sure, big, bouncing balls filled to the brim with cum and a cock that would make a horse feel insecure!"

"Right away sir," Jessica threw a mock salute and hurried down the hall to the living room. At the computer she clicked a few things, opened some menus and typed for a bit. When she was done she turned to Nikki with a grin, "In a minute you'll be literally hung like a horse and this time you'll see the difference."

"Sure I will," Nikki smiled at her friend and absentmindedly scratched her balls through her boxers, "Until then I'll just stand here in shirtless and boxers looking stupid while you grin like an idiot."

"Yup," Jessica agreed.

"Yeah," Nikki snickered.

"Hung like a horse," Jessica reminded.

Determined to get the last word in, Nikki thought fast, "A real stallion under the sheets."

"Total stud."

"Cock like a -" Nikki stopped abruptly, realizing that her balls were resting heavily against the fabric of her boxers and her cock felt oddly constricted. Looking down she saw that the front of her boxers was bulging, "What the...?"

Hands shaking, Nikki pulled down her boxers and looked at herself. What she saw shocked her.

Her cock was growing before her very eyes, and not in the sense that it was getting hard, more than that her foreskin was darkening and thickening, taking on a mottled appearance. Gingerly, she pulled it back to get a better look at herself and gasped. Her cock head had grown wider and flattened out, no longer looking remotely human. Below her balls were swelling and darkening.

When the changes finally stopped her flaccid cock, was a foot long and if she was sure if she hadn't been so frightened by what she was seeing it would have been even longer. Her grapefruit sized balls bounced against her thighs, aching and full of cum. Through her fear she could tell that it was easily the worst case of blue balls she had ever had. Weak with fear, she fell to the ground, her massive equine cock and balls resting on the carpet.

"Believe me now?" Jessica asked, staring at Nikki's enormous endowments.

Nikki nodded, fearfully, "Can you...can..."

She trailed off, unable to get the words out.

"Change you back?" Jessica finished for her, "Sure."

A click later and Nikki's cock and balls were back to their normal, human proportions. Gingerly, she touched herself, just to be sure everything was as it should be.

"So, Jessica said slowly, "You want to have your pussy back now too?"

Nikki looked at her uncomprehendingly.

"Right," Jessica nodded to herself, "The settings. I put it so you and everyone else would think you always had a cock and balls. You believe me about that?"

Nikki frowned, looking down at her anatomy. This was what she remembered, felt so normal for her that it was impossible for her to imagine having a pussy. Just the thought made her shudder. Having a guy penetrate her...that was frightening, but at the same time she had seen first hand a demonstration of what the Chronivac could do.

After a time she shrugged, "I believe that you could do something like that, but I don't know. I mean I remember always being this way and it feels natural enough. Honestly, I don't think I'd even like having a pussy, sitting down to pee, having to worry about periods, getting pregnant and all that. I like what I've got now."

"Suit yourself," Jessica turned back to the computer, "There anything you would want to change?"

That was an interesting question, one she had never considered before.

*Jessica changed herself instead

Payback

Nikki was miffed - her friend had acquired this computer program, changed her genitalia (allegedly) and was now mucking with her own body to try and get thrill at her boyfriends expense...

She sat down at the computer and found that the Chronivac program was still running - she grabbed the mouse, opened the window and looked around the program. Jessica's profile was still active, her changes represented in the avatar on screen. Nikki clicked the 'Undo' option and set the awareness option to 'unaware'.

Minutes later, Jessica came down stairs - Nikki flinched, expecting a rollocking from her friend for undoing her changes... "What's up babe, looking to make some more changes? Chris will be over in a minute - make sure it's not something obvious as I don't want to tip him off!" Jessica quickly said, continuing into the kitchen and started fumbling in the kitchen.

Nikki uttered 'Yeah, sure...' as she looked down at her prominent crotch.

Scanning over the profile options, she saw the option to drill down into different body parts, changing features beyond just 'adding' and 'removing'. She clicked on the crotch of Jessica's avatar, then expanded the 'Advanced' tree. Clitoris, Labia, Vagina, Hair were all available to alter. Moving down to the Male tree, the options for penis size & girth, a separate option for testicles were available (pretty much confirming that Jessica had probably just done a bait & switch on her private parts). Interestingly, selecting 'Penis' did not remove any options from the female tree.

There was a knock at the door - Jessica ran past & Nikki quickly minimized the window. "Found anything cool? Tell me later... me and Chris are going upstairs for some, ahh, well... you know. Speak later!" She ushered him in and up the stairs, firmly closing the door.

Nikki rolled her eyes and returned to the screen. She looked through the File menu and saw the Recent tab - she clicked on it and saw her name in the list. She clicked on it and the avatar swapped to a fascile of her body, complete with her hair in its current pony tail, her ample breasts and the penis and testicles she had carried for her entire life. She clicked on the history tab and was presented with what was (apparantly) the truth:

Recent Changes -
Added: Male Genitals.
Options: Replace existing; Awareness (Self): None; Awareness (Other): None; Awareness (User): Full; History: Complete.

Nikki was distraught. Her friend had lied to her. Or had she - the computer program worked, such was clear. But this was her penis. She'd had it from birth. The confused acceptance from her parents & doctors. The changes during what could be considered her 'puberty'. Her outwards appearance as a girl at all times, apart from sports at school, where the teasing happened, but wasn't bad - she was one of the girls, although she had a penis. But was it all true? Had this computer magically invented this entire history for her?

The decision was made. Nikki was going to pay Jessica back. She looked up stairs, shook her head in response to the bed creaks, giggles and moans, switched profiles back to Jessica and lept into the options...

Addition: Male Penis
Location: Replace - Clitoris
Awareness (Self): None;
Awareness (Other): Full;
Awareness (User): Full;
History: None;
Duration till completion: 30 minutes;

Nikki sat back, took a deep breath and clicked 'Apply'. A smirk appeared on her face, satisfied that revenge would soon be hers. She closed the program, headed up stairs and to her room. Her pocket pussy was waiting...

*Jessica's change happens on cue...
