Jessica stared at the program in-front of her, still not believing what it could do. She'd gotten it in an anonymous email last night that somehow slipped through GMail's spam filter. She gave it a thorough check with anti-virus software before opening it and when she did, she was presented with something that looked like a cross between the Spore Creature Creator and a 3D modelling program.

In the middle of the screen was a 3D model of a faceless, androgynous humanoid form. Jess found she could use the mouse to rotate it, zoom in, zoom out and basically look at it from whatever angle she wanted. There was a whole slew of toolbars on either side of the image but what caught her eye after the model was a drop-down box at the top of the screen.

Opening it, she found her full name - Jessica Maria Reilly - there, even though she hadn't entered it into the program. She clicked on it and the 3D model turned into an incredibly accurate render of herself, albeit naked.

Five-foot-four, sixteen years old, long dark hair, amazing heterochromic eyes (the left one ice-blue and the right an emerald green) and a toned body from years of various martial arts. Of course, the muscle didn't detract from her womanly features - a pert backside you could bounce a coin off and shapely long legs that she loved to show off. To her annoyance, the program had also perfectly rendered her rather unimpressive B-cup breasts. They were the main part of her body that she wasn't happy with.

She opened the help and spent the rest of the night running through some of the tutorials. Somehow, the program could alter a person's physical form, not just the 3D model of them, but the real person! The tutorials were reasonably straight-forward but even then she kept to the simple ones out of a sense of caution.

These were just altering proportions a bit, changing hair colour and length, age alteration, but there were far more options there that she hadn't used and was blown away by the sheer scale of what changes could be made (this was after she recovered from the shock of realising these were actual changes to her own body, mind).

Earlier that day, she'd asked a friend of hers to come over. They'd been friends since Jess came to the US from Australia back when she was 14 - courtesy of Jess' family moving in next door to her - and had even gone out with her at one stage about a year ago. Despite the sex being fantastic, it just didn't feel right going out on a date or something and so they both called it off. Since then, they'd had a sort of friends-with-benefits relationship, although they dispense with the benefits if either of them is seeing someone. She hadn't told her about the program, figuring she wouldn't believe her if she didn't have some sort of demonstration.

Now she was just waiting for her to arrive.
 
Katherine hadn't heard Jess quite so enthusiastic in some time now. When she'd called her over earlier she'd seemed to barely be able to talk, falling over herself to get her words out, though when Katherine had asked what the huge rush was there had been no answer beyond something along the lines of "you'll see when you come over". Well, Katherine had always been a curious person, so she'd gotten understandably antsy waiting for the time she could come over.

It was probably that curiosity that had drawn her to Jessica in the first place. When the two had become fast friends there had been something of a spark...it had piqued Katherine's natural curiosity. She'd never even considered a relationship with another girl before, but following that curiosity had led her into it. Things had been great, the sex, the dates...but at the same time it just hadn't felt quite right. The steady relationship ended mutually, but fortunately they had remained friends. Katherine wondered if perhaps Jessica had called her over for one of their semi-regular nightly sessions. Neither of them were in a relationship right now, and it had been quite some time since either of them had really dated anyone. Still, as exciting as that was, Jess didn't normally get that excited over arranging that.

On arriving at Jessica's house Katherine had just let herself in, it had become the norm for both of them at each others homes. She just slipped off her shoes and headed upstairs, following the familiar route to Jessica's bedroom and just strolling into the bedroom without even knocking. All the more fun right? Especially if she caught Jessica in the middle of something. Sadly though, she seemed to just be sitting at her computer. "Hey there Jess, I'm here. So come on, time to spill the beans on what was getting you so over excited earlier"
 
As usual when she was at home, Jess wasn't exactly dressed to the nines. Just a pair of rather-miniscule shorts and a loose tank top that, were it any looser, would not be fit to wear in public.

She smiled as Katherine came in, taking in the sight before focusing on why she'd called her over. "Hey. Weird program turned up in my email last night. Not a virus, I already checked with Dad's old laptop," he'd long since gotten a better one, but an expendable machine came in handy for checking these sorts of files. "And... well, just watch."

She switched back over to the program, which was still on her. She'd already settled on the change she wanted to use to demonstrate what it could do and had already made it on the 3D model, all that was left was to hit Apply. It wasn't a spectacular change, but it also wasn't the sort of thing that could be faked. Normally, her hair came down to about level with the base of her shoulder blades - not quite as long as Kath's, but not by a particularly wide margin - and she'd set the program to lengthen her hair until it came down to just past her backside. She hit Apply before Kath could comment on the fact she had a naked, hi-res, 3D model of herself on her computer and her scalp tingled as her hair lengthened out, the ends pooling slightly on the seat.

"Take a look," she said, holding some of her hair out so Kath could get a good look and see it wasn't faked, "you alter the program's image of someone and you can apply those changes to their actual body in moments." She watched Kath's expression as she explained, though one corner of her mind was already working out what sort of fun they could have with the program today.
 
"Weird program?" Katherine raised an eyebrow and folded her arms beneath her chest. What in the hell was Jessica talking about? "You actually bothered checking out some weird program that turned up in your e-mail? Seriously? Isn't that pretty dumb? Just delete that crap" Katherine waved her hand and rolled her eyes, though as Jess turned to it Katherine's attention was drawn to the computer. "When did you get into all that 3D modelling stuff? Huh...that's actually pretty good..." She moved in a little closer, the model was very detailed....way too detailed. When had Jess gotten to practice to be this level? "So was this what you wanted to show me? You're some computer animation wizard now or something?"

She looked at the model as Jess wen't to hit apply. Why was there an apply button? Was it because of the model having longer hair than Jess herself did? Had she gotten this good at computer modelling just so she could try out new looks without actually having to try them out?

Katherine had been so focused on the model that she almost missed what was happening to Jess, but she caught something in the corner of her eye and turned, opening her mouth to speak, but when she saw Jess' hair lengthening before her eyes all she could do was gasp. "Wh-what the...?" She stared, mouth gaping open for a few moments, before slowly reaching out to feel the hair that Jess was offering to her. It definitely felt real. "No way...no way" She shook her head. "No I'm not falling for it. Come on, those are extensions or a wig you were hiding or something. No way a computer program can change someone's actual body" Katherine folded her arms once more. "Making it look like your hair is growing is just some special effect trick from a TV show or movie or something"
 
"Yeah, but a film studio's costume department doesn't have to worry about the viewer being able to check every inch of the hair from root to tip and simple camera positioning can give the illusion without any CGI or fancy props." Jess watched a lot of behind-the-scenes stuff for TV shows, films and some youtube filmmakers like Corridor Digital and RocketJump.

"But, if that's not enough to convince you, let's try something else. Give me a change to make, anything you can think of. If this is all props and prosthetics, how many possibilities do you think I accounted for? Or that I could hide in this outfit?"
 
"Yeah yeah, but you watch so much of that stuff you'd know exactly how to try and trick me with it. I'm not falling for your pranks again" Katherine grinned confidently, certain that for the first time ever she had actually managed to figure out a prank Jess was pulling on her. She felt rather pleased with herself actually.

"Something else huh? Let's see....probably got one of those inflatable bras on under that top...keeping it nice and loose to keep it hidden" She tapped her chin "I bet you really have covered everything you know I could think of...so here's an idea. I bet you made one of those models of me too didn't you? So come on, why don't you do something to me instead? Then I'll know it's not a trick since I'm not in on the act" Katherine smirked triumphantly, no way Jess would be able to pull that off. "Do something crazy that I can't possibly not notice to me and then I'll know you're not just trying to pull my leg"
 
Jess tried to hide the smile from her face at Kath's suggestion. She knew a few tricks related to manipulating people. Kath had effectively given her carte blanche to change whatever she wanted.

She made a show of looking her up and down, as though seriously thinking about what to change. In truth, she was really just trying to figure out if she was wearing a bra or not (it wouldn't be the first time she'd not bothered bringing one - normally when she was over on a day like this it would just end up spending more time on the floor than around her torso).

"Okay, let's see you rationalise this one," she said before turning back to the computer and switching the program over to Kath. After a second or two of loading, a detailed model of a naked Kath appeared on screen in the classic T-pose of un-animated character models. Flipping open the panel for chest-related modifications, she dragged the slider for Breast Size up until the model sported a pair roughly the size of basketballs. She hit Apply before Kath could remark on the size and watched for the results.
 
Katherine's smirk didn't waver as Jess looked her up and down, she was just making a show of this, had to be, trying to drag it out as long as possible to try and make Katherine doubt herself, well it wasn't going to work. Well, not this time anyway. "Come on, you're stalling. If you don't do something soon I might just take my sweet ass back home and leave you to torment yourself with your imagination" She flicked her tongue seductively as if to emphasise the point.

When Jess changed the model on the screen Katherine glanced over at it, unable to help a small chuckle. "I knew you'd have one of me ready to go. Geez...you didn't have to be quite so accurate with it y'know, you could've flattered me a little bit at least" She watched as Jess brought up some controls and messed with something, then raised an eyebrow as the breasts on the model increased in size by several times over. "....Are you saying I should get porn star mega implants or something...?" Katherine glanced down at her modest sized bust in the t-shirt she was wearing, then back up just in time to see Jess hit the apply button.

"Ok, so what's supposed to-" Katherine cut off as she felt an odd tingling sensation in her chest. What was that? Had to be her imagination right? But then she felt almost...tight? Why did her chest feel tight? She looked down again, the gasped, almost screamed, as she saw her t-shirt bulging, slowly seeming to be filling up and growing tighter by the second. "Wh-what in the...?" She stumbled away from the computer, staring down at her chest in shock as the t-shirt continued to stretch, the fabric quite quickly beginning to strain and stretch. Katherine couldn't help but throw her head back and groan from the unusual sensation, fists clenching tightly at her sides. Within a few more moments, the fabric of the shirt could take no more, and with a mighty ripping noise it burst open as her still growing breasts spilled free, bulging and growing until they had reached the size Jess had specified on the screen, leaving Katherine panting slightly for breath, looking down at herself. "H-how...? N-no way...." She reached up, gently prodding one of her breasts, gasping as she really felt it, the flesh wobbling for a moment. Despite their new larger size they were still exceptionally firm and perky.
 
Jess' eyes were locked on Katherine's chest as the change started, the shirt swelling as it was forced to contain more and more tit flesh. She'd been expecting Kath to pull it up over them but was apparently too shocked to consider saving the garment (not that Jess didn't have some spares she could borrow). She couldn't help but stare at them as the shirt finally gave way, letting the oversized orbs out.

It was one thing to see the size on a 3D model, but another to be faced with breasts larger than your head directly. "You did say to do something crazy," Jess pointed out smiling while trying not to let it turn into a smirk, "I figured this would do the job without freaking you out too much."

She was also tempted to point out that the funny thing about con artists (or, in her case, those with the potential to be decent short-con artists) never bluff.
 
"I..that...you..." Katherine looked up. "I didn't think you were serious! I...this is.." Katherine took a few steps forward, breasts bouncing freely with every movement that she made. "I mean...how is this even possible? They're real...they really grew...but...but..." She just stared down at herself, prodding each of her breasts several times as her brain processed what had happened and finally started to catch up with reality. "This is...it's...it's amazing. Though if this is what you think wouldn't freak me out then I'd hate to see what things you considered that you thought would freak me out"

Katherine prodded her breasts again. "They don't even feel any heavier when I stand here...but..." She cupped herself, lifting her breasts slightly. "They definitely are heavier if I lift them"
 
"Yeah, I noticed that when I tried it on me last night, too," Jess admitted, her eyes still glued to the massive mounds, "I think it's doing a bunch of muscle and spinal reinforcements as well to help support the weight. Give me a feel." She rolled her computer chair forward until they were right in her face, there was no sign of stretching or any flaw; they looked as natural as any other breasts. What Jess had failed to mention was that, to anything more than the quick prods Kath had been giving them, they would be several times more sensitive than they were normally. So Jess listened for her reaction as her hands came up to lift the two orbs from below.

The extra weight was certainly there and they had that perfect balance between firmness and softness, which Jess tested with a light squeeze of what fit into her hands. She shifted both hands to one breast as she continued her "inspection", gently pressing her hands into the soft skin. She was curious to see how much of this Kath could handle with the extra sensitivity. She had plans for what they could do with this program and they'd be best served by getting Kath past the shock.
 
"Oh so that's what you really wanted, to feel me up?" Katherine smirked slightly, then just put her hands on her hips, pushing her chest forward slightly as if proudly presenting herself as Jess wheeled herself over. When Jess lifted them up though it felt....different. She managed to bite her lip to suppress a noise, but why did just lifting them feel like that..? When Jess actually gave them a squeeze though, there was no way Katherine could suppress the light moan of pleasure, her nipples immediately hardening before Jess' eyes. "H-hey...a-ah...that....it feels....ahhh...." She moaned again as Jess used both hands to squeeze at a single breast, the flesh yielding to Jess' fingers.

"H-hey..this...this is kinda unfair now isn't it...? Though...ooooh....g-guess I can't complain..."
 
She couldn't help but grin at her reaction. "We can even the scales up later if you still think this is unfair," she said before leaning forward and gently kissing the side of the breast, her hands still gently massaging the rest. She left a slow trail of kisses running along the side of the breast but stopped just at the edge of the areola, changing direction to teasingly circle around the hardened flesh.

After making a full circuit of the enlarged nub, she started kissing in towards the centre, finally planting one soft peck on the end of the nipple before sliding her lips around it to gently suckle it while her tongue teased at it. She was getting more eager now, shifting her hand over to the other breast to gently rub and pull at its nipple. Thankfully, she could still see Kath's face and kept her eyes on it to watch her reaction.
 
Katherine released a very definite moan as Jess kissed at her breast whilst massaging it, then grunted with every next kiss that Jess planted on her, panting with anticipation as she got closer and closer to her nipple...then released a loud whine as Jess changed direction. "You tease....god damnit you know I hate that..." She grumbled, but the grumbles soon turned back to grunts of pleasure as the kissing around her areola continued, until finally the girl was kissing in towards the center.

"Ah...ah...ooooooh!!" Katherine moaned loudly as finally her nipple was sucked and teased, her huge chest pushing forward a little more into Jess' face. "Nnngh...it...it feels way better than usual..." She panted heavily, already feeling more aroused than something like this would normally get her. Her breasts, her nipples, they were so much more sensitive than before, to pleasure at least.
 
Jess continued her ministrations, even gently biting at the nipple in her mouth and tugging just to let go and see the whole breast snap back into shape with a wobble before capturing it between her lips again.

After a couple of minutes, she shifted slightly and pushed both breasts together, their hardened nubs rubbing against each other before both were trapped between Jess' lips, her tongue sliding around and over both while her hands continues to press and squeeze the plentiful flesh behind them. She was curious to see if she could get Kath to cum just from this; she had managed it on herself the night before but would that be the same for Kath?
 
After a few minutes Katherine had to let her body fall back down to sit on the bed, her knees were shaking and barely able to support her anymore due to the pleasure that was tearing through her body. It was so unusual to feel such intense pleasure from her chest alone, it was like having a clit on the end of each breast. Ontop of that was Jess' expert tongue...oh god she'd always known how to use it, when to suck, when to lick, when to use her teeth. "Ooooh! J-jess...I..." The pleasure was building, Kath's body shaking. It almost felt like an approaching orgasm but.....this was different. Maybe because nothing had come close to touching between her legs yet, Whatever the reason Kath didn't care, it felt too good.

"Nnngh...a-ah...ah...AH!" She arched her back, crying out as she suddenly came hard inside her pants, her chest thrusting forward into Jess' face, smothering the girl with her giant breasts.
 
Guess so, Jess thought to herself as Kath went over the edge, not letting up on the overgrown nipples to try and keep Kath's orgasm going. As it finally ended, Jess pulled back and stood up to admire the sight of a post-orgasmic Kath. Her top was long enough to hide her shorts, but she was sure Kath would be able to smell her own arousal. She had so many ideas for what they could do with this program.

"Still think it was a stupid idea for me to check this program out?" she teased. "Care to try it out yourself?"
 
When Kath's orgasm was finally done Kath collapsed backover to lay on the bed, panting for breath. Despite now being laid down her huge breasts were still perky and sticking up into the air, practically defying gravity with their firmness. "O-ok...so....maybe not stupid..." She took a few deep breaths to try and recover, then used her arms to push herself up slightly. "Try it out huh...? Well...sure" She grinned slightly. "But first you gotta tell me what you've already tried, can't go repeating old material, I gotta do something new to you"
 
"A lot less than you'd think, actually," she said, sitting down on the bed next to her, "what I've done to you for a start, obviously. Mucked around with my height and muscle build a little, more just getting a feel for the UI and see how to do what. Was a bit too tired last night to do much else; didn't sleep much the night or two before it arrived and it all kind of caught up with me at once."

"But, considering what I'm wanting to use it for today, I'm sure you can think of something to do to me that'll be fun." And if she couldn't think of anything, Jess had a few ideas. But she'd seen some of Kath's porn collection.
 
"Your muscle build huh? Is this where I start calling you Jess Schwarzenegger?" Kath smirked, momentarily picturing Jess with giant muscles, before looking to the screen to focus her attention. "Hmmm...well let's see here shall we?" She grinned, then waved her hands to shoo Jess away. "Go on, you have to wait by the bed, you're not allowed to watch. You surprised me so now I get to surprise you"

Kath was more than ready to wait for Jess to comply with her demand, before looking back to the screen, starting to look through the various options. She wasn't looking at the obvious ones though like the sliders already on the screen. No, Kath was looking at the sides and top of the screen, looking for the hidden and obscure options that Jess might have overlooked and not found yet.
 
Smiling, Jess stayed seated on the bed while Kath went to work.

There weren't any hidden options, per se, just options that Jess had never used. The flexibility was impressive; features for adding additional limbs or other body parts, even ones that the subject would not normally have. She hadn't used it, but Jess had noticed the options that would give her things like additional arms or even turn her into a hermaphrodite. She hadn't used it, but she had at least double-checked some safety features in an .ini file so that stuff that the program would keep certain options (or uses for those options) from being harmful as well as setting her own maximum sizes that the program wouldn't go beyond (although, if the breasts hadn't given that away, they were still well beyond what would be considered natural).
 
Kath saw the options for additional limbs, grinning as she thought about how Jess might appear with 4 or 6 arms...hm...maybe later. Eventually however she came across the settings to grant Jess body parts she wouldn't normally have, including options for human male parts and even non-human parts. Her grin only widened at those. Sure Jess had almost certainly found these options herself, but she probably wasn't expecting Kath to find them quite so quickly, Kath wasn't as computer savvy as Jess after all. With a few clicks Kath was able to select the options, and making sure she was obscuring the 3D model from Jess she was able to add a cock to it. New menus came up, allowing Kath to start making adjustments to the length and girth, which she decided to set to well above human norms. She also ticked several options related to cum, specifically ones pertaining to "enhanced volume".

Just as Kath went to click apply though, her arm accidentally knocked against the keyboard. Without even realising it Kath had hit a shortcut for a copy option, duplicating the cock so that it added an additional one to Jess as well, the model now having two giant cocks sprouting from the same spot. Kath's back was already turned though, looking at Jess with a grin as she clicked her finger down on the mouse, the pointer already hovering over the apply button.
 
One thing about the program that had confused Jess (well... beyond the obvious aspects, of course) was that the copy-paste function defaulted to one of the thumb buttons on her mouse. She'd been meaning to find the part of the options that would let you change key bindings but had never gotten around to it the previous night. It wasn't so much a copy-paste feature either, but a duplication. Had Kath still been looking at the screen, she'd have seen an extra popup for setting where the new cock would be in relation to the first; either in an over-under layout, by default, or adjacent.

While Kath had been playing with the program, Jess had surreptitiously removed her shorts and tossed them behind the far side of the bed where she wouldn't see them. Her top was long enough to hide their absence and she figured they would just be getting in the way sooner or later. As the now-familiar tingling sensation started just above her clit, she figured she'd made the right call.

A bulge quickly appeared under her top, growing rapidly until the source was long enough to be visible under the shirt's hem. Jess smiled as she saw the clearly-male appendage start to emerge. Guess she found those options after all, she thought to herself, before she realised why it looked slightly off. There were two of them, one above the other, and from the rate they were growing, Jess guessed that they would be big.

Leaning back on the bed, she groaned at the sensation of both cocks growing and hardening, soon just dropping to the bed as she wrapped a hand around each length which soon became too thick for her fingers to encircle. As the sensation finally passed, she took stock of her new equipment. Both shafts were hard as rock in her grip, which was struggling around their coke-can-sized girth, and towered a good foot-and-a-half above her while copious amounts of precum were steadily flowing from the heads.

"Well, not quite what I was expecting," she joked, looking back at Kath to see her reaction.
 
Kath watched with glee as she saw something happening beneath Jess' shirt, the top starting to push out and bulge. It was happening, it was really happening!! Though even Kath was surprised as she saw not one, but two, letting out a slight gasp. "Whoa...!" She glanced back at the screen, noticing that she had made a slight mistake, but quickly looked back to Jess in order to continue watching Jess' new cocks growing and growing, unable to help licking her lips at the sight, barely able to hold back from outright drooling over the sight.

"So uh...how do they feel...?" She watched as Jess grasped onto them, though they were still growing, soon too big to hold properly. "Oh man...so big...." She licked her lips again, finding herself scooting the wheeled chair closer towards Jess. "Even seeing it...oh man...so hard to believe...not the only thing that's hard though it seems"
 
((OOC: Sorry for the slow reply; allergies kicked my ass yesterday and it's a little difficult to get in the mood to write something like this when your nose is doing its best impression of Niagara Falls.:p))

Her hands slowly slid up and down the massive pillars, fingers occasionally tracing the prominent veins bulging across their surface. "Mmm... they feel great," she sighed. The look in Kath's eyes just made her even more eager to put them to use.

"I hope you're not just going to sit there and watch," she joked, gently squeezing both cocks for a moment before aiming the upper one towards her own face, leaving the head just inches from her lips, "otherwise I might have to take care of things myself."

She punctuated the remark by gently flicking her tongue across the giant head, eliciting a deep moan and sending a shiver through her body, both growing stronger as a dollop of precum landed on her lips.
