The Impossible Program (closed for me and ThePrincess)

Alison shivered as she felt Jess' cock prodding at the entrance to her pussy once more, though this time it felt even thicker and harder than before, then cried out as it pierced her, plunging into her. "HNNN!" She closed her eyes, groaning loudly as her body was pulled back, sliding inside of her quickly and easily, at least as easily as it could given the size, inside of her, then passed through her cervix like it wasn't even there. "AAHHH!!" Alison cried out in orgasm from the sensation of her womb being penetrated and stretched so much so quickly, her entire body shaking, the girl almost collapsing from her hands and knees on the bed. "O-oh god....th-that's....that's so good...." She panted, about to ask for a moment to recover before her new tail was suddenly grabbed.

Alison's eyes went wide as it was suddenly stroked, then cried out as it was pushed into Jess' pussy, instinct taking over and the tail pushing itself up as deep as it could go. "O-ooooHH!! Th...that...o-oh god! Oh god!!" The tail felt so good...though Alison could feel something was missing...it was as if the tail could be brought to the brink of orgasm, but never quite pushed over the edge. Well....maybe things would have to be done to fix that later. The tail quickly started to move, thrusting into Alison, swirling and writhing around, Alison drooling over the bed beneath her as pleasure overwhelmed her mind.
 
Jess cried out as she felt her pussy being stretched by the thick tail. "Holy shi- AAHH!" was all Jess managed to say as the tail forced its way deeper, already hitting her cervix. She was starting to see why Alison had been screaming like that while being fucked earlier and she screamed again as the tail pushed through into her womb. She managed to stay in control of herself long enough to see her stomach bulging out from the massive shaft forcing its way into her before losing herself to the pleasure the way Alison had done.

The main difference was that Jess still had a few remnants of coherent thought left, enough for her to lean down and grab Alison's breasts and using a third hand to rub at her clit before starting to thrust her own giant organ into her, her fourth hand on the bed to try and somehow keep her balance. She drove her cock as hard and fast as she could into Alison while Alison's tail tried to do the same to her. Through some quirk of timing, they managed to get some form of rhythm going - Jess becoming impaled on the giant tail every time she pulled her mammoth organ out of Alison. She wasn't in a state to think about it, but both of her genitals were linked - one wouldn't cum until the other did (Alison's pussy and tail, however weren't linked like this - just as well otherwise it would've been impossible for her to cum). It was probably the only reason she hadn't started convulsing in an earth-shattering orgasm the moment that tail had pushed into her womb. Despite that, her cock was already twitching like mad and she had no idea how long she could last before filling her friend with cum again.
 
Alison hissed in pleasure as her breasts were grabbed, feeling the sensitive marshmallowy flesh being squeezed by powerful hands, whilst other hands were rubbing furiously at her over sensitive clit, which was being stimulated doubly by the huge cock thrusting into her over and over, stretching Alison's body in ways she never would've thought possible. Then again they probably weren't...it was this program...this glorious program....Alison would certainly have to get a copy for herself....oh she couldn't wait for that.
"Nnn...aahhh....ooooh!" Alison groaned and writhed around on the bed, causing her tail to shake inside of Jess' pussy and her own pussy to wiggle and squirm around on Jess' cock, only adding to the stimulation the girl was already receiving. "C-come on Jess....y-you....you can do.....m-more than that..." Somehow Alison glanced back over her shoulder and gave a slightly evil grin to her friend. "Y-you've fucked me...harder than this....before....sh-show me what....you really got...."
 
"Nn.. AH, alr-ah! Alright then." Jess managed to squeeze out. She brought her lower hands to Alison's hips while her upper hands, reluctantly, pulled away from her breasts to hold her arms. "You asked for it!" she said before using all four arms to pull Alison hard onto her cock while thrusting her hips forward to slam the whole length into her, crying out as she pulled out again and impaled herself on Alison's tail before driving the massive shaft into her again, slowly picking up the pace of her two-foot-long strokes and filling the room with the loud smack of their hips meeting.

Once more, Jess felt her orgasm bearing down on her and she could tell it was going to be insane. "Ah, I... hope you-nnn... you're ready for more cum because... here. It. C-AAAAAHHHHHH!!!" Her eyes rolled back as she impaled Alison on her cock, thrusting it deep into her womb as it swelled and erupted with cum, her pussy clenching around Alison's sensitive tail and spraying her juices onto the bed. Jess pulled Alison upright, her breasts pressed against her friend's back while she went back to playing with Alison's clit and breasts, leaving one hand on her expanding stomach.
 
Alison may have asked for it, but she wasn't quite prepared for what Jess did to her. "Ah!" She yelped as she was lifted up, eyes going wide as she found herself suddenly impaled, her scream of pleasure echoing through the house, probably loud enough for the neighbours to hear....then again they were probably used to hearing Jess and Alison crying out in pleasure when they were together.... The pleasure was so intense...Alison could feel her body being stretched, her pussy widened and her womb stretched beyond all imagination...and then there was her tail....oh god it felt amazing when it plunged into Jess over and over again!

By the time Jess screamed out, Alison was barely coherent, almost drowning in pleasure. The warning of orgasm snapped her back to reality for a moment, but all it did was make her even more aware of her own orgasm when it struck at the same time as Jess' own. First came the mind shattering sensation of pleasure that ripped through her body, but then came the sudden feeling of fullness. Almost instantly Alison felt her belly starting to swell quickly....she already knew it was going to end up far larger than a mere basketball as it had been before...and she was loving every second of it.
 
Jess' pussy was cumming like mad around Alison's tail, the orgasm from there being dragged out to match the one from her cock. She couldn't think, her hands on Alison's breasts and clit running on autopilot as she continued to pump her friend full of cum. Already, Alison looked like she was about nine months pregnant and still growing.

((I'm not sure how big I want to make her go; normally about this big is as far as I normally go, but I'm happy to go further, maybe about double the current size or so?))
 
((Doube sounds good to me if you're ok with that ^_^ ))

Alison felt a second orgasm being triggered as her belly continued to slowly grow, her body pushed a little off the bed due to her laying position. "NNnnnghh! Oh god! So full! So good!!" She cried out, her tail going wild inside of Jess' own pussy....oh god how Alison wished it could cum...that she could feel what Jess was feeling, but there was certain to be plenty of time for that later. "HNNN! Ohhhh!" Alison looked down at herself, then somehow managed another orgasm simply from the sight of her inflating belly.
 
Eventually, the insane flow of cum stopped and Jess tiredly rolled her and Alison over onto their sides, her cock still stuck deep inside Alison's pussy. Her two upper hands played with Alison's breasts idly while the other two gently rubbed her swollen stomach - which was now so big you could be forgiven for thinking Alison was about to give birth to quadruplets.

"I... I think we should save that tail for special occasions. I couldn't think straight for a bit there." she said breathlessly, her cock still rock-hard and twitching inside Alison's pussy. Not that it would be seeing any more use at the moment, though - if the way Alison's tail had been going earlier was a sign, she must've been eager to try out a cock of her own.
 
((Apologies for the late response))

Alison was panting heavily when Jess flopped down beside her, Alison's belly still sticking out a good ways infront of her, groaning as her breasts were played with. "Nnnn...a-ah....s-so...so full...oh fuck...so full...." Her tail slowly slipped out of Jess' pussy, dropping down between them on the bed, finally seeming to go limp due to Alison's current lack of energy. "Y-yeah...special....occasions.....m-maybe next time....it can cum too...." She grinned slightly, glancing back at Jess over her shoulder.

"G-god....I feel like I could sleep for a week......I've never been so exhausted after sex before.....not even that time you set me up with those three guys at once....." She blushed and giggled softly, then leaned back a little to nuzzle into Jess softly, pressing against her 4 pillowy breasts. "Just a little rest....."
 
((It's fine.))

Jess grinned a bit remembering that night - she'd originally gone along to make sure the guys backed off if Alison told them too and the end result had been a wild night for all involved. Shifting her hands off Alison's breasts and onto her stomach, Jess held her close as the two girl's fell asleep - both of them out cold until the next morning.

Jess woke up first (a rarity for her) and, after a little shock and confusion before remembering what happened the night before, looked down at Alison's stomach. Sometime during the night, Jess' cock had softened enough to let all of the cum she'd pumped into Alison flow out, though even soft it had been big enough to stay inside her. Carefully extricating herself, a process that left her cock rock-hard again, while trying not to wake Alison; Jess went over to the computer and reversed their physical changes and ran a clean-up option that removed all of the cum they'd both drenched the bed with the day before, as well as any that was still inside Alison. Figuring the other girl would be up soon, Jess headed downstairs to make breakfast, not bothering to put any clothes on as she did - her parents weren't going to be back anytime soon and she wanted to give Alison a good eye-full during breakfast.

So that she wouldn't write off what happened as a dream, though - Jess had left the program open on her computer with Alison as the current subject.
 
Alison yawned as she awoke, slowly sitting up and rubbing her eyes. "Nnnnn?" It took her a moment to remember she was in Jess' house....though that explained why she was naked at least. "Mmmm....?" Memories began to flood back of the previous night....it was all so fantastic that she dismissed it as a dream at first....that perhaps she had passed out from the pleasure or something and then had a crazy crazy dream.....until she spotted the computer, the program still running and displaying Alison. "Oh my...." The girl covered her mouth, staring for a moment before a slight grin made its way onto her lips. "Oh wow...." She licked her lips, then sniffed the air, smelling the scent of breakfast from downstairs. "Mmmmm......" She sniffed a few more times, then went to grab one of Jess' robes, pulling it on to cover herself up and turn to head downstairs.

"G'morning..." Alison walked into the kitchen and blinked, spotting Jess standing there naked, a blush creeping onto her cheeks. "A-ah...hello...." Alison smiled, her normal shy personality showing through again for the time being. "That was....one hell of a night huh?"
 
Jess grinned as she saw Alison come into the kitchen. "Yeah, it was," Jess said as she slid her arms around Alison's waist, pulling her into a deep kiss, one hand lowering to give her butt a quick squeeze. "Hope you're up to using it some more today." Jess had other ideas, but she'd worry about them later.
 
Alison groaned as she was pulled into the kiss, shivering slightly. Normally the morning after was a rather normal affair...the two just hanging out as friends rather than lovers once again. This felt....different. Then again last night had been different as well. "Oh yeah.....I'm definately up to that..." She grinned softly and licked her lips, looking at Jess seductively....until her stomach grumbled loudly, a combination of hunger and the smell of breakfast overwhelming her lust. "Uhhh.....right after we eat anyway...." She blushed in embarassment, rubbing her head, suddenly reverting back to her normal, shy, public self.
 
Jess couldn't help but giggle at Alison's change when she remembered about breakfast. "Alright - should be about done cooking by now." she said before, reluctantly, pulling away from the other girl and grabbing a short robe she'd left on the counter in-case Alison was back into her shy-mode. She'd made a few things that she knew Alison liked as well as some pancakes, bacon, eggs; even Jess herself was sometimes surprised by how much of a big eater she could be.
 
Alison laughed nervously as she went to grab a robe for herself too from the cupboard, knowing well by now where they were kept, this wasn't their first near-naked breakfast together after all, covering up her front as she went to sit down at the table. "Ah...wow....it all looks and smells so delicious!" She grinned happily, then almost immediately started to dig in. Despite her shyness, Alison could burn through her energy rather quickly when she did get exciteable....after sex it wasn't unheard of for her to eat enough food for 3 or 4 people to regain her stamina.
 
Breakfast went by surprisingly quickly, the night before probably having taken more out of them than they realised. In any case, once they finished, Jess stood up from the table with a look on her face that Alison would find very familiar. She slowly walked around the table, a sultry swing in her hips and the fingers of one hand lightly trailing along the table, before smoothly slipping into Alison's lap and sliding an arm around her shoulders while the other reached for the belt of other girl's robe.
 
By the time breakfast was over Alison felt stuffed, leaning back in her seat with a loud "Ahhh" and unceremoniously patting her stomach. "That was great, you always make the best breakfast Jess" She grinned, then blinked as she looked up at her friend, blushing at the way she was walking...she knew that walk...all too well. "Um...." She shivered as Jess slid into her lap, arm around her, playing with the belt of the robe she was wearing. "You're uh.....you're thinking of what to do to me with that program again aren't you...?" She couldn't help but grin shyly, the blush on Alison's cheeks deepening quickly. "W-well uh....I wouldn't be....oppossed.....to...surprises...you know me....love surprises...."
