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, he found his 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, 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. Like a lot of girls, that was 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).

At school 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 and had even gone out with her at one stage about a year ago (though they had been somewhat discreet about it, for obvious reasons). 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.
 
Alison ran her fingers through her hair as she walked down the street, towards Jessica's house. At school that day the girl had been pestering all day for her to come over after school, seemingly excited about something, very excited. Well....maybe it had been a while for Jessica....Alison hadn't seen her with a boyfriend or girlfriend for quite some time....and Jessica did always have something of a high sex drive...well...she did after Alison had met her anyway. The thought brought a slight chuckle to the redhead, adjusting the backpack on her shoulder. Within it was her favourite double ended dildo, just incase that was what Jessica did have in mind. Well...even if it wasn't at first, maybe it would be pretty soon, they were both single right now after all, and it had been a while since Alison had dated someone herself. "Still....for her to get so excited...." Alison chuckled again, turning and walking up the path to Jessica's front door.

After knocking a few times, Alison opened up the door to let herself in as she always did, the two knew each other well enough to know they were welcome to just come and go as they pleased. "Hey Jess! I'm here!" Alison slipped off her shoes, then turned to head upstairs towards Jessica's room. She half expected....or maybe more hoped....that Jessica would be waiting naked for her up in her bedroom. With a slightly lecherous grin Alison reached the other girls bedroom door and pushed it open, glancing around. "Yo Jess, I'm here like you wanted, so what's gotten you so excited hm?"
 
By the time Alison arrived, Jess had gotten changed into something a little sexier. She was wearing one of her shortest skirts, thigh-high socks and a button-up blouse with only one button at breast-level done up. She also hadn't bothered with any panties (and wearing bras were a rarity for her - her tits still a bit too small to warrant one).

As Alison entered the room, Jess wrapped her arms around her and pulled her into a deep kiss, her tongue thrusting into the other girl's mouth as one hand squeezed her ass. This wasn't just for her own fun, though - with what Jess wanted to do with the program, it would be easiest if Alison was 'primed-and-ready'.

"Come and have a look," she said, after finally breaking the kiss, and lead her over to the computer, pulling the other girl into her lap as she sat down. "I don't know how, but this program can change a person's body. Watch." To demonstrate, Jess pulled herself up on the program, opened a flyout menu on the side and moved a slider along a bit. The graphic of her was now two cup-sizes bigger and, after Jess hit the Apply button, her own tits followed suit until she was sporting a pair of pert D-cups that were making that single done-up button on her blouse work overtime. "What do you think?"
 
Despite her hopes and expectations, Alison had been caught off guard by the kiss, though it most certainly wasn't unwelcome, and almost instantly she was returning it, thrusting her own tongue against Jessica's, the muscles wrestling with each other whilst Alison shivered as her ass was grabbed, oh she loved when Jessica did that....especially when they had just been out and about...mmm...the thoughts sent a shiver through Alison's body, letting out a soft groan of disappointment when the kiss was broken and Jessica retreated back to her chair, though giggled slightly when she found herself pulled into the other girls lap, leaning back slightly to use her small breasts as cushions.

"Hm? A program that can change a persons body? Jessica.....is this one of your kinky games?" Alison chuckled slightly "You should've said if you were in the mood for some roleplay, I could've brought some outfits over with me...." She licked her lips, then glanced over at the naked 3D model of Jess on the screen. "Huh, pretty good.....that really does look exactly like you" She smiled, then chuckled as Jessica made the models breasts bigger. "Oh come on Jess, I keep telling you that you don't need bigger tits, yours are great just as they-" She cut off and blinked as something pressed against her back, pushing her outwards a little bit. "Uhhhh....." Alison blinked again in confusion, then slowly turned herself around whilst still sat on Jessica's lap, squeaking at what she saw. "I....what?" She stared in amazement at Jessica's new rack, the shirt barely holding on now. "Whoa....."
Slowly Alison reached out, cupping Jessica's new breasts and giving them a gentle squeeze. "They.....they're....real....? But....how is that? Oooooooooh, I get it, you're wearing an inflatable bra aren't you?" She chuckled softly. "Is it controlled by your computer?" She grinned, then suddenly reached out to snatch the mouse from Jessica, bringing the breast size slider up even further. "Well let's just see what happens when I do this shall we?" With a slightly evil smirk, Alison hit the apply button, the model on-screen of Jessica now with a set of gravity defyingly perky G-cup breasts.
 
Jess grinned at Alison's reaction and wasn't surprised when she went for the breast size slider. That had been another reason she chose this older blouse, it was one she could afford to lose if she needed more proof but didn't just decide to unbutton the shirt. She also made a mental note about that computer-controlled inflatable bra idea; have it work with a smartphone app and there might be a market for it.

She groaned as her breasts started to swell, straining the single button holding her shirt closed and the nipples poked visibly through the thin material. The button didn't even make it through the whole change, the threads holding it on finally giving and it snapped off, bouncing off the back of Alison's shoulder in the process (and proving that any breast-expansion story involving buttons flying off with enough force to do any sort of damage are gross exaggerations). Her shirt fell open and her two now-massive breasts were on full display, the nipples hardened and Jess gave a confidant and almost predatory grin.

"Still think it's a fancy bra?" She asked.
 
Alison had turned around with a smirk as if expecting to see some kind of weird inflatable bra popping out of the blouse, but when it was bare flesh that spilled free, Alison just looked even more confused. "Uhhh.....whoa...." She blinked, then once again moved to cup the enlarged breasts, now lifting the bare flesh and giving it a gentle squeeze, then flicking her thumbs across Jessica's nipples. "They're real.....they're actually real.....? I....but...how can this be? I....this is impossible. Just a computer program? I....but...." She slowly tore her eyes away from Jessica's now plentiful chest and now looking at her face instead. ".....Uhhh....well.....no I don't think it's a fancy bra....I...don't know what to think now...." She squeezed at the flesh again, then slowly looked further down at her own chest. She'd always been a little bigger than Jessica, but now...well....Alison was practically flat chested in comparison.
 
Jess moaned as Alison played with her now-enlarged breasts, her pussy getting wetter by the second. It seemed that the extra size also made them a lot more sensitive. She responded to Alison's treatment of her breasts by sliding her hands up under the other girl's shirt and giving her tits a gentle squeeze. She'd always loved how well they fit into her hands, but now that they had the program...

"The program's not limited to being used on one-person, you know." Jess said, leaning forward to give Alison a quick kiss. "We could make yours just as big, if you want."
 
Alison grunted as Jessica squeezed at her breasts as well, her nipples quickly hardening and poking through her bra and tank top. "It....it isn't? You....could....? Feh....I don't believe you" Alison smirked slightly. Oh she believed Jessica alright, she just wanted to tease her a little. Slowly she lifted herself up from Jessica's lap. "I bet you couldn't do a thing to little old me with your fancy computer program...." She licked her lips seductively. "But if you can prove me wrong then....well....just maybe I'll let you do whatever you want with me....and to me...."
 
Oh and did she have plenty of ideas for what to do with - or to - Alison! The program wasn't limited to working with existing parts of the body, after all. But she'd keep that little tidbit to herself for now.

"Alright then - why don't you take that shirt and bra off? We don't want to wreck them and for you to have to walk home topless. Well... actually that might be fun." she joked before using the drop-down menu to bring Alison up on the program. Let's keep it simple for now, she thought to herself - mainly because she had a plan of her own - as she used the breast size slider to give Alison a big, perky G-cup like she'd given Jess. She hit apply and watched the result, one hand idly rubbing one of her breasts.
 
"Hmmm, well I guess the neighbours might like the view, but I doubt my parents would approve" She chuckled, starting to pull her top and bra off, throwing them over at Jessica in an attempt to obscure her view for a few moments, or cause her to mess up when working the mouse. "They already suspect me and you are up to a little more than the usual on our sleepovers after all" The girl put her hands on her hips, then blinked as she felt an odd tingling sensation. "Huh...? Ah!" She gasped as a shot of pleasure emanated from her chest, then slowly her breasts began growing out, swelling quickly, nipples also growing larger by the same amount, now sticking out a good inch on the end of Alison's perky breasts. "A-ahhhhh...that....oh wow that feels good.....and they don't even feel heavy..."
 
Alison had either forgotten how good Jess' reflexes were or just hadn't realised it, but she was able to easily catch the thrown garments (watching her take them off in the first place had helped, too). She'd never seen the change happen on anyone else yet - the closest she'd come was setting an apply timer (an interesting feature of the program) and standing in-front of the mirror as it went off. Seeing Alison's breasts swell like that was one hell of a turn-on and the hand on her own breast pinched the nipple, making her moan as Alison's change finished.

"I don't know why they don't feel heavy either. Not that I'm complaining - back problems would just get in the way." Jess said, before switching the program back to herself for a moment. "Here's another little trick with the program I learnt." she said as she loaded a preset she'd made last night and hit apply, minimising the program so that Alison wouldn't see what it was.

It started as a tingling just above her clit and the first Alison would see of it would be her skirt starting to be pushed out. By the time Jess' new cock had poked its way out from under the skirt, it was six inches long and still rapidly growing. When it finished, the massive pillar of meat was easily over a foot long and nearly three inches thick, precum oozed from the tip in copious amounts as the rock-hard shaft pulsed in-time with Jessica's heart. "What do you think?"
 
"Hm? Another trick?" Alison raised an eyebrow, then blinked as Jess did something to the program, but quickly minimised it away before she could see for herself just what had been done. At first, nothing seemed to happen, and Alison was about to ask what was going on, but then she saw it....then she saw a small bulge starting to form in Jessica's skirt. "No way....." Her eyes widened, stare fixated on Jessica's crotch as the skirt slid away to reveal a rapidly growing erection coming out of Jessica's body, swelling up until it was a good 13 or 14 inches long at least, and so thick that it was practically a third arm or leg. "Oh wow.....that's....big....bigger than any of my toys...."

As she stared, Alison couldn't help but lick her lips, slowly taking a step forward, watching as pre-cum oozed from the tip, pouring down the shaft. It was as if it was calling to her. "No fair....you get to have one first....when I get mine...." She grinned slightly. "I'm gonna make sure it's even bigger....."
 
"I hope you do," she said, taking a step towards Alison and letting the head of her cock brush against the underside of the other girl's breasts, "I added a little extra to the change so that, within some limits, the pussy of anyone touching this cock will be able to stretch more to fit it. You're still going to feel really fucking tight though - this is going to be one hell of a fuck."

She wrapped her arms around Alison again and pulled her into a heated kiss, their breasts rubbing together and her cock squashed between their bodies, smearing precum around between their breasts. Christ, she wanted Alison so badly; to feel those lips on her cock, to fuck her senseless and then fill her with cum. She could feel her pussy juice running down her legs, she couldn't wait to get underway.
 
Alison shivered as she felt the tip of Jessica's new cock poke at the underside of her enlarged breasts, leaving a sticky trail of pre-cum behind....damn that felt good on her skin. "Oh? And just what makes you think I'm going to let you use that thing on me...?" Alison grinned mischievously, before letting herself be drawn into the kiss, gasping into it as their breasts rubbed together, Alison too now feeling the enhanced sensitivity of them, their hard nipples flicking against each others, pre-cum coating their skin as well as practically pouring down Jessica's shaft. After a few moments, Alison broke the kiss, then immediately turned her back to Jessica, bending over, flicking up her skirt and tugging her panties down to around her knees.

"Oh fuck....I can't wait anymore Jess....you have to do it....you have to give me that cock right now!"
 
Jessica loved that sight of Alison bent over and desperate for a fuck. She only took a second to smear her own precum more evenly around her cock to make things easier, before lining the head up with Alison's pussy. With one hand on Alison's ass, she teased the other girl's folds for a moment with the tip of her cock, before starting to push it into her.

"Oh fuck!" Jess exclaimed as Alison's cunt stretched around her shaft, squeezing it tight and drawing another thick glob of precum. It was a good thing she'd grown this cock last night and masturbated with it for a while, otherwise the feeling as just the head made it into Alison would've made her cum right there and then. Instead, she just moaned loudly while forcing more of her cock into her. Soon she butted up against Alison's cervix. She knew that the other parts of the change would prevent any damage so she pushed against the entrance to her womb, soon feeling it open as she sunk the last six inches of her cock in all in one go, Alison's stomach bulging from the size of Jess' cock.

"Shit.. so tight..." was all she could say, the walls of Alison's cunt keeping a vice-like grip on her cock as she started to pull out until just the head was inside her. She then pushed slowly back into Alison before repeating the process a little faster. Soon, she was pounding away at Alison's pussy like crazy, the room filled with her moans and screams of pleasure and the sound of their hips smacking together.
 
"St-stop teasing damnit!" Alison grunted as she felt the tip of Jessica's cock teasing at her pussy lips, wiggling her hips to try and get it inside of her faster. Then when she felt it finally enter her....good god did Alison scream, a howl of pleasure the likes of which she had never made before. This cock....this cock was incredible! The biggest, the best she'd ever had. "NYAAAAA!" The girl had to thrust her arms forward to grab the side of Jessica's bed in order to support herself and stop from just falling to the floor. "Oh f-f-fuck!" Alisons newly enlarged breasts were swinging beneath, then she gasped as she felt the tip of the cock prodding against her cervix. So deep already? Then she felt Jessica continue to push, Alison closing her eyes and grunting from the oddly pleasureable sensation, then letting out a cry of pleasure as the rest of the cock was rammed in, feeling their hips meeting, the outline of Jessica's cock bulging out in Alison's belly.

"A-ah....oh god....oh god...." Alison's vocabulary was rather limited by the pleasure she was feeling, panting heavily, then starting to squeal and moan as Jessica began to fuck her like a wild animal, loving the feeling of that cock pounding into her over and over again. It was all just so much! Normally Alison could go for hours if she wanted, but this cock.... "I...I'm gonna cum....gonna cum already Jess! Oh god don't stop! D-don't stop pounding me with your cock!"
 
"F-fuck; I c-couldn't stop even if I wanted to!" Jessica cried out as she kept slamming her length into Alison. Her cock was twitching madly, she wasn't going to last much longer and still wasn't used to the sensations. She bent down and grabbed Alison's breasts, squeezing the heavy orbs while still fucking her as hard as ever.

"Shit! I'm gonna-" Jessica never got a chance to finish when it all became too much for her and she finally came with a scream of raw pleasure. Her cock swelled and erupted with more cum than any normal guy could've produced, pumping it directly into Alison's womb. Her pussy was also going wild, juices running down her legs. She lost all sense of time until the impossibly-intense orgasm passed, but her cock was still as hard as ever, ready for more.
 
Alison squealed when Jessica leaned down and grabbed at her heavy, swinging breasts, the orbs of flesh so much more sensitive than usual, and this intense fucking just seemed to be making them even more sensitive. "Nyaaa!" She cried out at the new sensation of having a cock pounding into her womb over and over again, oh god it was all just too much. Just as Jessica was about to announce her own orgasm, Alison came hard. Her cry of pleasure matched Jessica's, her pussy squeezing down on the girls new cock even more tightly than before, juices spraying across Jessica's mid-section.

But then...oh god then she felt that cum pouring into her womb, filling her completely in barely a spurt or two, yet there was no stop. The incredible sensation triggered a second orgasm in Alison's body before the first had even ended. Alison was seeing spots by the time the orgasm began to pass, her body shaking, now held up almost entirely by Jessica's still rock hard cock, though Alison wasn't in much of a position to do much, the two simultaneous orgasms having temporarily drained even her stamina.
 
Jess eventually got her senses back and lifted Alison's upper body up so that they were both standing (although Jess could feel that the other girl was only upright because of her weight on Jess' cock), her breasts squashed against Alison's back. She kissed and nibbled at the girl's neck while she caught her breath, but noticed something as she looked down at Alison's breasts.

She lowered a hand to Alison's stomach and realised it wasn't an optical illusion; her stomach had actually bloated from the sheer volume of cum Jess had pumped straight into her womb. Alison's skirt had somehow ended up low enough on her hips to avoid getting in the way of her stomach's swelling and the sight of the bulging stomach was actually turning Jess on even more (both seeing it happen to Alison and the knowledge that, later, Alison would be doing the same to her).

Not wanting anything to get in the way anymore, Jess pulled out of Alison and gently lowered her to the bed. Cum poured out of the girl's pussy once Jess was out, but she didn't worry about having to clean it up - the program had an extra feature to remove bodily fluids, presumably for just this reason - as she removed Alison's skirt and panties (the latter of which were still around her legs). The two girls moved into the middle of the bed as Jess went back to kissing Alison, their breasts rubbing together and Jess' cum-smeared cock rubbing against the other girl's stomach.
 
"Nya!" Alison moaned as she was lifted upright, the sensation causing her to move slightly on Jess' cock, only heightened by having her neck kissed and nibbled, oh she loved it when Jess did that. It was when Jessica's hand moved over her stomach that Alison herself noticed what had happened, gasping as she looked down between her breasts to see her swollen belly, so full of cum that she looked perhaps 3 or 4 months pregnant, a nice sized bulge thanks to her womb stuffed full of cum. Perhaps she should have been freaked out, but right now the sight only turned Alison on even more. "Oh wow....." She licked her lips slightly, then gasped sharply as Jessica pulled out of her, immediately allowing Alison's tight body to start pushing the cum out all over the floor, then all over the bed when she was lowered onto it.

"Ah!" Alison practically fell to the bed, her body not responding entirely the way she wanted, instead relying on Jessica to manipulate it for the time being. "Oh god....Jess...." She groaned as they kissed once more, though their enlarged breasts squashing together made it a little difficult to reach the other girls lips. She moaned into the other girls mouth, whilst her hands seemed to find the strength to come up and start rubbing at the cock trapped between their bodies, the shaft covered in a mixture of their fluids, Alison's fingers stroking up and down it slowly.
 
The feel of their hard nipples rubbing together and the way Alison's fingers stroked along her cock was driving her on again and she moaned into her mouth before breaking the kiss and shuffling down the bed. "God... I need you again." she said before once more lining the thick shaft up and plunging it into Alison's waiting pussy. It was still as tight as ever, but their cum let it slide in a lot easier than before. She went back to kissing her and rubbing their breasts together once their hips met, running a hand through Alison's hair as she started a slow rhythm of thrusts with nearly the full length of her cock. Jess wanted to drag it out a bit more this time, but she couldn't help moaning in ecstasy and gasping as her cock repeatedly pushed into Alison's womb.

"I... hope you won't be- aahh -too tired to fuck me soon?" she said, coming up for air before starting to nibble at the other girl's neck, knowing exactly where she liked it the most.
