“I need to grow more. I need more cum.” Was all Jane said, as she sat on Carl’s face, her huge ass bulging out of her dress, her cheeks spreading into him, and lowered her mouth over his huge, dripping dick once more.

Carl could feel Jane’s ass spreading wider, getting bigger and fatter as she gobbled down on his dick. And this time, he could feel her breasts pushing into his chest as she sucked down on his massive cock, slurping it hungrily and greedily once more. He knew her tits were getting bigger all the while, and marvelled at where it all might end. But all he could think about was his growing cock, which was swelling even now, as Jane sucked on it, his balls gently expanding too, filling back up with cum, ready to be blasted back into Jane, to further increase her growth, to pump her up even bigger, to make her big as a house. He couldn’t wait.

The thought of Jane becoming the colossal giant she’d always wanted to be, the kind of giant she talked about on the message boards of their site, with breasts the size of cars, 30ft tall, a true giantess, with Carl as her sex toy, just there to pleasure her, to being her to climax, to make her even bigger, was too arousing for words. It was something Carl so desperately wanted to make happen, so he kissed and licked her huge, growing ass, as it swelled into his face, huge and incredible, felt her swelling boobs pressing into his chest, and prepared to blast another huge load of cum into her waiting mouth, aiming to fill her belly up, to stuff her so full of cum that she would explode, jizz bursting forth from every orifice.

And with this thought, Carl came once again, this time more immensely than the last, his dick feeling like it was tearing down the middle, but somehow in a delightful, pain-free way, as his pumped up balls began to spray their swollen seed back down Jane’s throat.

This time she knew it was coming, and started swallowing immediately, sliding her hands up and down Carl’s huge shaft, making sure she milked him for every drop. As her breasts increased in size, her ass pushing out of her dress as she shook it in his face, Jane guzzled what must have been quarts of cum firing out of Carl’s cock. He felt like he was coming for about a minute, non-stop, and the pleasure he felt in his body was unlike anything he’d ever known – it was even more all-encompassing than last time.

Before long, it was over, Carl was finally done, but he knew now that his cock and balls were only going to get bigger. And he was absolutely ok with this.

Before that happened though, he knew it was time to enjoy the next stage in Jane’s growth. She clambered off his dick, already heavier and fuller than before, and stood there proudly in front of him, ready to show off her new figure. The first thing Carl noticed was her belly, which had almost doubled in size, and now stuck out like she had slid a pillow under her dress, except this bulge was perfectly round and full. She patted it again, loving how stuffed she looked, how ready to burst her belly was. The fact that it was crammed with cum, that was only going to make her more huge, was even sexier.

She belched once more, hugely and satisfyingly, and looked down as her body continued to grow. Her tits had swelled a lot while she was sucking Carl’s cock, and she now was sporting a gigantic pair of watermelons, that had stretched her dress to an ungodly degree. The whole garment looked like it was painted on, and with her 6 months’ pregnant belly, her massive tits, which were nearly as large, and her giant ass which she showed off as she turned around, Carl felt his giant dick pulsing with energy once more, swelling and growing to meet demand. His balls were now like large golf balls, hairy and huge, getting slowly bigger all the while, filling back up with precious cum, ready to blast more of into Jane, to pump her up more and more, to new gigantic heights.

Jane looked down at her tits, which stretched out so far in front of her, and knew her dress wasn’t going to last much longer.

“I can’t believe it hasn’t burst already.” Smiled Carl, looking at Jane with dewy eyes, unable to believe how sexy she was, now that she was so huge.

“I had it specially made.” Jane grinned, as she slowly inflated larger. “Made out of a space-age fabric that has about 3 times the flexibility of normal clothes. Even then, I don’t think it’s going to last – uhhhh.”

As she said that, she doubled over, and her whole body began to grow. It was like someone had clicked the corner box in some image manipulation software and pulled the mouse – Jane began to grow in every direction, spreading outwards. Her clothes began to pop and tear as she grew up towards the ceiling, bulging outwards. Her belly stayed its huge, full and round self, while her breasts expanded to match, gigantic and wobbling and full, looking like they were going to burst at any moment. She turned to the side to give Carl more of a view, and he almost came there and then to look at the tremendous curves that she was displaying, her ass absolutely gigantic, her breasts as big in the other direction, if not bigger, her huge stomach rounding out the picture with its tremendous, swollen, stuffed to burst overhang.

Her dress could barely contain her, and started to pop apart, as she grew taller towards the ceiling. She was taller than 7 feet now, towering over Carl, getting bigger all the while, stretching up towards the ceiling, which was only a few feet above her.

“I’m so big.” She purred, rubbing her breasts hungrily, playing with her hard nipples as her dress shredded itself further. She continued to spread out of it, the fabric tearing apart, her huge thighs expanding to meet one another below her cunt, her massive ass breaking the back of the dress while her titanic breasts, which were now resting on her colossal belly, continued to bulge outwards.

Carl looked down at his own cock, which was now close to 10 inches in length, and almost passed out from arousal. He reached down to grab his balls, and loved how thick and full they were, larger than golf balls now, well on their way to tennis ball size. He knew they were filling back up with cum, and he was eager to pump it into Jane, to make her bigger and bigger, until all their dreams came true.

Jane was looking down at his increasingly immense cock and balls, and was clearly having similar thoughts. She leaned down to kiss the tip of it, and sucked it up and down a couple of times, slurping up some cum that was left on the shaft, and that had dribbled out of Carl’s huge tip in the meantime. When she stood back up, there was a glorious moment where her head bumped into the ceiling, and Jane realised that for the first time, she was too big for the room.

“I’ve been waiting for this moment.” She grinned, as her dress finally burst off her, leaving her huge, beautiful and naked. “I can barely fit in here, and I love it.”

“I love it too.” Carl smiled, looking up at his perfect giantess, who was now having to lean forward to fit in the space, grinning down at him with her huge mouth, which had grown along with the rest of her. Just as well, as Carl had a very big cock indeed that would need to fit in. But Jane was very much up for the task.

“Well, if I grow much more in here, I’m going to struggle to get out. What do you say we move into the main room for the main event?” Jane smiled, looking down at Carl, who she was now nearly twice the size of. Her breasts were like bowling balls on her huge frame, her stomach huge and full, and her ass was completing the look at the back. She was incredible.

Carl pulled himself to his feet, his cock sticking out like a giant divining rod in front of him, pointing the way. Jane reached down, grabbed it, and pulled him towards the main room. She got to the doorframe, and had to squat down to be able to fit through it. Even then, her huge tits got stuck, and it was only with some considerable effort that she bulged through, almost on all fours by the end of it, her giant belly almost dragging along the floor. Carl got a great look at her huge ass, still gently swelling, as she popped through the door into the huge living room, with its massive, vaulted ceiling, stretching up about 30 feet. This would be the place for the final bout of growth, and they both knew it.

Carl looked up at Jane, who was now about 11 feet tall, practically twice his height, completely naked, with breasts the size of overinflated beach balls, as well as a huge, full, protruding stomach, still growing all the while, and looked down at his giant, throbbing cock, then back up at Jane.

“What do you say we go all the way?”

“I thought you’d never ask.” Smiled Jane, who swept the couches out of the way with relative ease using her massive arms, and then lay down, ready to accept Carl’s humungous foot long rod into her giant cunt.

Carl straddled her massive legs, unable to hold himself back as he slid his phenomenal cock inside Jane’s tight pussy. Even the size she was, her cunt was incredibly taut, and ready to receive his massive girth. He rested himself on her giant stomach, reaching up to grab her colossal breasts, which had grown even bigger in the interim and were now the size of large medicine balls, and began to fuck Jane.

“Oh my god.” She moaned, her voice deeper and fuller, now that she had grown to such a giant size. “You feel incredible. Now make me truly huge.”

Carl could barely speak to agree. He just set his mind to the task. He was going to make her the biggest he possibly could…

To BE concluded…
