The sensations Carl was feeling as he was fucking this growing beauty were almost beyond description. He loved feeling her huge, taut belly, stuffed with cum as he pumped his giant rod inside her. He loved how huge his balls had become, now nearly the size of tennis balls, massive and full and ready to burst. He loved that she was growing larger all the while, her breasts swelling up towards the ceiling, her back arching as her butt grew even bigger, her belly giant and stuffed. And all of this was so sexy to Carl, that he knew he was going to pop. Again. He couldn’t believe how many times he’d come in the last few minutes, but it was going to happen again, and he couldn’t wait. There was a certain window for these drugs, and the more he came, the more the both of them grew. So his objectives and what brought him physical pleasure were intimately aligned, and so he forged forwards, thrusting harder and faster, bringing himself to climax while his busty, giant beauty swelled larger all the while.

“Oh fuck, I’m going to-” Carl was unable to finish this thought, as his giant cock and balls exploded once again into action, firing off huge, thick salvos of cum into Jane’s gaping, waiting cunt.

“Oh yeah, fill me up B1g B01, make me huge.” She panted, as he came an insane number of times, just going and going, coming and coming. What was incredible was that Carl could physically see Jane’s belly inflating this time, being pumped up by the wild quantities of jizz he was firing into her. And this only made him come more – seeing his thick semen filling up this beautiful, perfect, bulging beauty only increased his resolve, and squeezed a few more giant blasts of spooge out and into Jane’s waiting cunt.

Her belly distended outwards to a ridiculous degree. Anyone would think she was 9 months’ pregnant, ready to pop at any moment, but they both knew it was all cum.

“Ohhh, I’m so full.” Jane moaned, as her belly filled with thick, creamy jizz, stretching upwards, lifting Carl into the air as it inflated, like it was a balloon, and Carl’s cock was the pump, blasting it bigger and bigger and bigger.

All the while they were fucking, Jane’s breasts had been expanding too, spreading down towards him, and it was only the scale of her belly that had stopped her breasts from bulging down into him and spreading over him. But Jane’s belly was so full and stretched so high that her colossal breasts were instead resting on that, huge and full and ready to burst.

“Ohhh, I think I’m…yes, I’m lactating.” Jane muttered, placing huge hands over her impossibly large breasts, which were absolutely stuffed together, with permanent cleavage, so huge and wide that they had no choice but to smoosh into each other at all times. Carl looked up, and could only see belly and breast. Huge towers of flesh overwhelmed him as he stared, in paradise.

“Ok, we need to shuffle down, my head’s nearly in the fire.” Jane smirked, her voice now so huge and deep, she was so massive, and Carl decided to step up and see her for the first time in her new form. He had to keep walking back as she dragged herself to her feet, her legs going on forever, her belly so enormous the only thing that made it look small was her breasts, which were the size of giant bean bags, but stuffed completely to the max with beans, utterly full, leaking milk out of the ends of nipples that must have been the size of whiskey glasses.

She stood up to her full height, and she was considerably taller than the second storey.

“Wow, I’m over 15 feet.” She grinned, looking down at her body. She was nearly 3 times the size of Carl, and the sense of power and grandeur she gave off was intoxicating. Carl had assumed he had reached the peak of his arousal, but every time either he or Jane grew, his lust and thirst for her grew with it. His dick was now around a foot and a half, and constantly erect, his balls the size of soft balls. They made it hard to walk, and his giant dick was at constant threat of knocking things over, but the sense of power and strength that came from it was worth every thing.

“Come up here.” Jane purred, from high up on the second storey. Carl ran his eyes up her body, and loved everything he saw. He loved that if he stood too close to her, all he could see was the huge overhang of her belly. And if he stepped back, he could only see the almost-as-huge hang of her giant tits. It was only way back that he could see her beautiful, perfect, massive face.

Carl moved to take the stairs, but then he heard a deep giggle, and then a huge hand came down, picked him up around the middle, before depositing him on the second floor, where he sat on the wooden bannister, his gigantic cock sticking up, laughably long and huge.

“I’m glad to see you’ve grown to match.” Jane smiled, though Carl wouldn’t exactly say they matched. Not that he minded.

“But I want more. I’m nowhere near big enough yet.” She smiled, her head now almost half as big as Carl was, and lowered her huge lips onto his cock, sucking him off again. It was amazing how adept she was, despite her giant size, and the fact that she was so enormous and huge was such a turn on for Carl, that he didn’t think he was going to be able to hold on for long at all.

“Make me huge. I was to be so big and full that I can’t move.” Jade whispered, deep and low, as she gobbled down on his massive, still growing cock. His balls swelled and pulsed, growing larger all the while, as his massive dick extended into Jane’s huge mouth. It wasn’t able to fill it, as she was just too big now, but it meant she could give it a really good sucking, and it felt incredible. Jane gobbled him like a seasoned pro, determined to get every scrap of cum to fill her already enormous belly.

And then, before he knew it, Carl was coming again. His insanely large balls were pulsing with pleasure, ready to blow again, and his cock, which was swelling into Jane’s mouth, even as she continued to grow taller, was ready to blast off once more. This time was going to be incredible though – he knew it. His balls were going into overdrive, and the eruption was going to be off the scale.

“Oh fuuuuuck!” Carl moaned, as his cock turned into a fire hose. It was like someone had plugged it into a huge hydrant of cum, and there was no way to stop it. He was blasting like there was no tomorrow, firing straight down Jane’s throat into her belly, which he could hear distending as he filled it up, like a water balloon attached to a tap. Her stomach was groaning outwards, filling up with jizz as his immense balls went into overdrive.

He didn’t stop coming for 3 minutes – 3 minutes of absolute nirvana as his pent up balls emptied themselves into Jane’s mouth. Even at the giant size she was – and she was still growing at this stage, her breasts practically smashing the second floor, her belly doing similar as she grew bigger and taller all the while, her ass doing similar to the parts of the structure it was bulging into behind her – he managed to fill her mouth and start to stuff her cheeks. There was just too much cum to consume.

But eventually the flow began to ebb, and Carl began to return back down to earth. He looked down, and realised he was high in the air, above the second storey. He looked up to see Jane’s face, and realised she was nearly hitting the ceiling.

“I’m about 25 feet, baby.” She boomed, her grin wider than he was tall, her huge mouth able to eat him in one. At this size she looked so beautiful he could cry, her huge body impossible to take in, it was just too massive. He looked down at her belly – what he could see from up here, as her breasts, which were the size of small cars, were blocking off most of it. But he could see her enormous, distended belly, and the fact that she was now wedged in where she stood, unable to really move. Unless she wanted to start breaking things. But for now, she was stuck.

“Time for the final stretch.” She whispered in Carl’s ear, and he looked down at his cock, to see that it was about 4 foot long, which given he was 6 ft tall, was quite something. To have a dick that large, as well as watermelon-sized balls crammed in either side, ready to blast more cum, was all it took to send him over the edge.

“Take me down. Time to fuck you through the roof.”

Jane kissed him on his huge dick one last time, able to bite it off with a single move of her massive teeth, and pulled him around, past her car-sized breasts, past her hot air balloon-sized belly, near her impossible ass, and then placed his massive cock down there, ready to fuck her.

“I can’t see you, is that right?” She boomed, as Carl was now below the huge overhang of her stuffed belly, her giant breasts resting above.

“Just a bit forward.” He shouted back, and his huge cock, still growing, slid inside her massive cunt, and they started to fuck. She was basically using him as a dildo at this point, but Carl didn’t mind. He’d reached a stage of ecstasy where he basically felt he’d died and gone to heaven, all his desires having been pushed way beyond what he’d felt was possible. Clearly Jane knew this was going to happen, clearly she’d known all along, clearly he’d been “played”, but as Carl wanted the same thing, he didn’t have a single complaint. He simply wanted to come inside his gorgeous giantess until they were both as big as they could be. He wasn’t going to last long.

Hearing her moans, seeing the monstrous overhang of her insane stomach and breasts, knowing just how big she was, and how much bigger she was going to get, Carl before long was firing one last salvo of immense jizz into his perfect giantess.

“Oh gooooood!” He cried, and Jane did the same, as their growth accelerated. Carl’s cock spread outward, pushing deep into Jane’s massive cunt, while his balls expanded to the size of basketballs, gigantic and huge, still stuffed with cum, no matter how much they fired out. He could feel Jane grow bigger, as she stretched towards the roof. He could feel her huge hand tighten around him as they both came, Jane’s head soon bumping into the roof, forcing her to bend over as she grew, her body getting taller and taller. But she couldn’t bend over too much, as her breasts and stomach were so massive there wasn’t enough room to go around, so before too long she was shoved up against the ceiling of the cabin, far taller than 30 feet, her breasts now like small trucks, spreading over her insane stomach, stuffed so full of cum it was like it was going to burst open, her tits leaking milk, which dropped onto the floor in huge splashes. Carl only wondered what effect drinking that milk would have.

Soon she had to put him down, away from her, or she would have crushed him. She was too big – there was too much of her in every direction, and she was still growing. Carl stepped back away from her huge legs, in the center of the cabin, by the fire, and heard a huge crunch as she grew through the roof, smashing through it, her breasts crunching through the house, her massive belly not far behind.

“I’m so huuuuuge!” She boomed, in a voice like thunder, as she erupted through the ceiling, larger than the massive cabin that Carl had through would contain them.

He could barely see her from down here – all that was visible were her massive legs, and some of the overhang from her insane belly. But Carl knew – he knew there were stupendous breasts, an ass to die for, and that amazing, beautiful face, way up there, 40 feet above him and still growing.

And he looked down at his phenomenal cock, which was now 6 foot, as tall as he was, and his balls, which were more like big hairy beach balls that anything resembling human anatomy, and he gently, slowly began to pleasure his huge shaft. He didn’t want to break this combo, that was for sure.

He knew what he and Jane both wanted.

To be bigger.

Always bigger.

And he sat down, exhausted but exhilarated, and thought about what they should do next.
