"Adam..." Simone said, snapping him out of his reverie. He realized he had paused for a few seconds, staring into her eyes and seeing the same crazy gleam he'd witnessed back then. "I want you to fuck me while I grow."

Before he even realized what he was doing, Adam had his belt unbuckled, and his pants halfway off. Realizing in an instant that he still had his shoes on, he slid out of both of them as if they'd been greased, then ejected himself out of his jeans. It seemed like she hadn't even finished her sentence by the time he made it to her, his left hand trailing against her breast still as he slid around her body, and she leaned back eagerly as he entered her.

"HUUUUUNNGGHHH!!!" Simone shouted, and her breasts exploded in a wave of growth, resulting her ass being pushed directly into Adam's groin as he went for his second thrust. It was a miracle he didn't blow his load right then. But he'd been mentally preparing the entire week for this moment, and steeling himself during the car ride to anticipate the bucking that was sure to happen, as it did every time.

She was growing faster than he was prepared for, that was sure. But he managed to hang on. In that moment, he felt his feet being slowly pushed backwards, and it was only the sheer absurdity of what he was experiencing - riding a wave of boob flesh through the forest, that helped him keep from coming. Instead, he focused on trying to strategically find places to set his feet in the dirt as he passed over it, so that he could continue a good thrusting rhythm. Just focus on the rhythm, and don't pop, he thought to himself.

Meanwhile, Simone was yelling with each thrust, as her breasts grew in waves, each surge of growth coming shortly after he thrusted inside her. Adam glanced up at the rising wall of boobs beyond Simone's head, and he realized she was now bigger than the last time she'd allowed herself to reach her full size. There was no way she'd even come close to fitting in the apartment, not even if they knocked down all the walls. And she was still growing.

"HUHH!" Bigger.

"HUHH!" Bigger.

"HUHH!" and even bigger, Simone's breasts kept growing, pushing them both back, rustling the pine needles and leaves as they swelled.

Part of Adam, the rational part, had hoped that maybe her growth would have slowed down, that it would eventually stop. They were already too big to be let out, indoors. They had to stop eventually. Or, well... the other part of Adam, the twisted part, filled in the rest of that fantasy with maniacal glee, imagining his girlfriend outgrowing the whole forest. What if she just... never stopped? Just kept growing and growing forever?

Wondering what that would be like sometimes kept him up at night, and with conflicting feelings about the rock-hard erection it inevitably caused. She was crazy, that was sure. She never wanted to stop growing. He could tell, because every time they had sex, she was always thrilled to grow - to not only reach the limits of her current size that she always kept contained, but to exceed them.

She was insatiable, and he felt the urgency of that desperation with every thrust, as he rode his girlfriend backwards through the woods. Pushed on a wave of growing breasts that were so big, they defied description. Adam experienced it as just a wall of pale flesh in front of him, punctuated by a line of cleavage that reached to the heavens. Bigger and bigger she swelled, her tits continuing their relentless advance across the forest floor.

There was probably still daylight up there, if he looked upward. But his attentions were focused much lower. He could feel things rising to a crescendo. He noticed that Simone's rate of growth was slowing down, that she was reaching the limits of her real size. Her reverse thrusts were also slowing down, as if she were preparing for something. Adam positioned himself in anticipation of what was coming, what came every time during these sessions. He leaned forward, and then felt her body shudder.

A ripple passed through the wall of breasts in front of him. And then: "HAAAAAAAAAAAAHHHHHHHHHH!!!!" Simone screamed in ecstasy as she came, and a massive surge of growth pushed both of them several meters backward. At that moment, Adam mentally released his own floodgates, allowing a torrent of cum to flow out of him, as he pumped frantically, clinging to Simone's shoulders to get some kind of grip, slipping in both of their sweat as he grasped for a purchase.

At that same moment, Adam heard loud, deep cracking sounds echoing in several places around the campsite, sounding like repeated thunderclaps. The trunks of the trees were being pushed outwards, he realized as he continued to release. After a few seconds, and a few more loud cracks, Adam felt the growth slowing once more, until finally, the couple ceased being pushed back, as they both collapsed against Simone's breasts, panting hard.

For the next few minutes, the two lovers caught their breath as they cuddled each other, leaning into the soft, pillowy breasts in front of them. Adam slid one hand gently down Simone's back, rubbing around her waist sensually, feeling the slick sweat that coated her body. With the other hand, he reached up and intertwined fingers with her. He leaned down to kiss her neck, and she reached her other hand around to stroke his face, and run her fingers through his hair.

Truth be told, this was always Adam's favorite part of the experience. The timeless moments after both he and Simone had climaxed, when they could enjoy each other's bodies, almost like normal people. As much as he was enraptured by Simone's gargantuan breasts, he enjoyed the rest of her body, too. He loved her. All of her.

But unfortunately, this was the only time when he could experience her fully. And even now, their contact was limited; he was stuck in this position, standing upright while he leaned against her from behind. It wasn't like he could flip her over, or lay next to her in bed, or cup her breasts in his hands while they cuddled. The bigger Simone got, the more Adam found himself wishing there was some way they could just have normal sex, at least sometimes

.

All of these thoughts swirled around in Adam's brain, but his body continued to attend to Simone, stroking her all over, tenderly squeezing her bum. She turned her head backwards and they began kissing each other, still breathing hard. "Simone, I love you." he whispered in between kisses.

"I know," she whispered back. "I love you, too."

They continued to make out, with Adam angling his body around to her side so she wouldn't have to crane her neck so much. As he slid his cock out from between her cheeks, still rock hard, he felt cum dripping out from the end of it, leaving a slimy trail on her butt as he moved around to the side.

The oddness of their situation, and of just having had sex outside, suddenly struck Adam, as he felt the afternoon breeze passing across his sensitive tip, still coated in his cum and her wetness. He glanced up to see that the leaves of the tree canopy were gently swaying in the wind that passed through the woods.

For the first time, he caught a glimpse of just how big Simone now was. Her cleavage extended a full two stories above them, blocking out half the sky from his vision. This is crazy. This is absolutely nuts, he thought to himself. It wasn't the first time he'd had these sorts of thoughts, after they had sex. But this time, another thought came unbidden right afterwards: I have to get away from her.

That thought wasn't exactly new either, but it startled him with its intensity, this time. Adam paused for a brief moment, before continuing to reposition himself better for kissing. The thought burned in his brain, demanding further analysis, but it wasn't the time for that, right now. He shelved it away for later, and focused on Simone.

She was eagerly returning his affection, and as they kissed each other, it was her tongue that pushed into his mouth, first. "Babe, you're so big." Adam whispered in between kisses.

"Oh yeah?" she asked softly. "How big am I?" and her eyes focused on his for a moment.

"So big," he replied, and they made out some more.

She always loved this type of talk, afterwards. Adam had started doing it the first time by accident, just stating a fact that came into his mind every time she reached her fullness. But it was clear that Simone found that statement incredibly sexy when he uttered it. In every session after that, it always became part of their pillow talk routine, and between them, it was Simone who enjoyed it more.

For Adam, he was still partially just stating a fact. She was so big. And yes, he did find it incredibly sexy. But the astonishment at her size grew every time, and more and more, when he found himself telling her how big she was, it was more because she wanted to hear him say it, than because he wanted to say it. Or at least, he wanted to say it, but part of him didn't want her to take it as a compliment - but rather a warning. She never did, though.

"Yeah, I'm so big, baby," She said back to him, kissing him hard.

"You're so big."

"So big."

Back and forth they went like that for a little while, in between passionate kisses. It was nonsensical dirty talk, and it was all Simone ever seemed to want after she grew. Once, Adam had tried some racier language, to see if that would give her a thrill. "Yeah, you're my big dirty growing slut," he had said, but when he tried to kiss her after that, she pulled away immediately.

"No," she'd said firmly. "Not a slut. Just big." Her eyes made it clear that there would be no argument about this. The comments about the size of her breasts thrilled her, but she didn't want to be seen as a slut. Comments about how sexy she was were fine, and she always liked hearing his professions of love in the heat of the moment. But degradation was off the table, and she always had to be in complete control.

A couple times, he'd attempted to steer her into some gentle BDSM roleplay, once by grasping her arm more firmly and pinning it behind her back, asking if she liked that.

"No, stop it." was the firm response, and he'd immediately released her.

The other time, he said in an admonishing tone, "You're TOO big. Maybe you should be punished. With a spanking." And he smiled down at her suggestively, inviting the role play.

But she shut that down as well. "There's no such thing as too big." she declared, then seized his head from behind to kiss him. There was anger in her eyes when she did so.

"No such thing as too big," Adam found himself repeating back to her, in between kisses. But part of him wondered if that was really true.

Their sexy talk continued for a few more minutes, gradually winding down in intensity, until they both fell silent and just held each other for a while. Adam moved to Simone's other side, so she didn't have to keep her head turned in a single direction, and could avoid cramping her neck. He felt his cock's stiffness slowly melt away as they calmed down, and kept feeling its sticky wetness pressing against Simone's thigh. He leaned his head on her shoulder, and both of them closed their eyes and cradled each other from their awkward positions for a few minutes.

Eventually, Adam spoke up. "We're gonna need to drive all the way back to the camp entrance to take a shower," he whined.

Simone laughed softly. "Ugh, I know. I'm gonna be covered in so many pine needles."

Adam sighed through his nose. The comment brought back to mind the gravity of the situation, of just how big she'd gotten now. The undersides of her breasts would be covered in pine needles and dirt. Concern for her crept back into his mind. She'd gotten bigger than he'd anticipated, and he suddenly wondered if she was being poked by branches or scraped by tree trunks. "Babe, are you, uh... okay... everywhere? Are the trees poking you?"

Simone looked up at him, then her eyes seemed to look into the distance for a second. "Ow! Now that you mention it... yeah. I'm getting poked from a couple different places," she snorted a laugh, and her eyes focused back on his. "It's funny, I didn't even notice, until you said it. I guess there's just a lot of me to take in."

Adam smiled down at her. "You got that right, babe," he said, as he lightly smacked her breast, before pushing himself away from his leaning position against her.

Slowly stepping backwards, Adam was better able to take stock of the tremendous size of Simone's breasts. They were wedged in between several tree trunks that scattered irregularly around the edge of the clearing, but not totally penned in on all sides, yet. The wider part of the campsite still had space on either end, although not much. Adam looked around for his pants so he wouldn't have to walk around in just a t-shirt, but they were nowhere to be seen. They must have gotten covered. Naked from the waist down except for his socks, Adam started picking his way through the woods around the campsite, slowly making a large circle around Simone. His mouth gaped as he took in her massiveness.

All together, both of her breasts combined were easily as big as a house, although since they were somewhat trapped by the trees, they'd been pushed higher than they would be on totally flat ground. When he got to her front, he came to her right nipple, which had grown larger in proportion with her breasts, and was about the size of a large trash can. It distended firmly.

Out of curiosity, he stepped up to it, and wrapped his arms around the engorged nipple, seeing if he could encircle it with both hands. He pressed his body against it as he squeezed it, but he only managed to lightly brush his own fingertips. A few seconds later, he felt a shudder pass through Simone's breast, and his arms were pushed outward as the nipple swelled a bit. A loud *CRACK! * sounded from the tree trunk a few feet away as Simone's breasts grew a little more, and Adam quickly released the nipple and stepped back. A shower of small twigs and leaves fell down from the canopy above, as the trees around her were jostled again.

Adam shook his head as he stepped away, feeling frustrated with himself, and Simone. Why had he touched her nipple like that? Wasn't she big enough? Why did she have to keep growing every time he touched her - couldn't they just enjoy each other, as they were?

In truth, the post-coital funk had descended upon Adam, and all the doubts he had been suppressing now came to the front of his thoughts. When she was growing, when they were having sex, he was unable to think straight. All he wanted to do was make her feel good, and to feel good himself. But this... he craned his head to look up at Simone's breast, jammed up against the tree trunk. A scowl crept onto his face as he observed how his sick fantasy was coming up against reality. This was too much. She was growing out of control, and they were running out of places where she could let herself loose. And he was making it worse by enabling her. For her sake, he wracked his brain, thinking of a way to somehow get her to stop. If it was even possible for her to stop growing. He started moving again, finishing his circuit around Simone.

When he came back around to her other side, he found her leaning contentedly into her own bosom, hands splayed out to either side in a wide embrace of her breasts. Her eyes were closed, and she was smiling. She always looked so happy after sex, in stark contrast to his own feelings of melancholy and shame. "Sorry for squeezing your nipple," he said somewhat abashedly, scratching his head. "I hope the branches aren't poking you too bad."

"It's fine," Simone sighed, not opening her eyes. "The poking isn't that bad." She rubbed her hands slowly over her expanse of skin. "It just feels so good to be big."

Adam stared at her from behind, wanting to say something. But it just... didn't feel right, to bring up his doubts right now. He knew she wouldn't want to hear it, not when she was luxuriating in her post-coital bliss. Not while she was finally comfortable in her own skin. Mentioning it now would only make her mad, and he didn't want to start the camping trip off on the wrong foot. They had the campsite reserved all week, after all.

But part of the reason Adam had planned for such a long vacation, far away from things she could damage, was that maybe, just maybe... he could find a way to convince her to stop her endless quest for growth. To seek out a cure for her condition. For now though, he decided to just go along with whatever she felt like doing, for a while longer. It was such a struggle for her to stay contained all the time, and she deserved this period of relaxation.

Standing behind her, he thought about stepping forward for another cuddle session, but decided against it. He didn't want to touch her again, and potentially trigger another growth spell. Maybe later in the week, they could find another time to be together, in a place that didn't have so many trees around. Maybe if he could find a big field nearby, and they went there after dark, just the two of them, and plenty of room for Simone to grow...

He felt his dick twitch lightly at the thought, and shook his head again. Not two minutes after saying you need to get her to stop growing, and you're already thinking of places for her to grow more, he thought to himself in disgust. You really are sick in the head, man. He found himself nodding slowly, agreeing with his own internal dialogue. He was sick, same as she was. But as much as he did enjoy seeing her grow, as sexy as he found the idea of her massive breasts, a part of him stubbornly clung to the idea of finding a good spot for her to just let loose. It wasn't that he wanted her to grow. What he wanted was to just be close to her, to touch her all over, to cuddle her, without worrying about the growth that would cause. That part of him wanted to be in a wide open space with her, where she could grow to her heart's content, and he didn't have to think about the consequences.

Having decided to avoid touching her for now, Adam found himself patting the sides of his bare legs, then wondering why he was doing that. He was looking for his keys, he realized, so that he could start grabbing things from the car. But his keys were in the pocket of his pants, which were somewhere underneath Simone's left boob, if he remembered correctly. Instead, he crossed his arms and stood behind Simone, waiting patiently while she relaxed.

"What are you doing back there, lover?" she asked, her voice partially muffled as she spoke with half her face leaning against her boob. He saw her open her eye and glance back at him. "Admiring your handiwork?" she asked with a small smile.

Standing with his arms crossed, Adam supposed that is what he looked like right now. He uncrossed his arms and laughed softly. "Admiring yours, babe."

"Come here," she said softly, and Adam took a few steps closer. But he held off on getting too close, instead letting himself gawk openly at the contours of her bust as he slowly approached.

"God, you're so big, babe. I can't believe you kept this all inside you for so long." He put his hands on his hips, trying to play up how impressed he was by her size, but also her self-control. Willing for that control to return to her, so she could act normal again. He didn't want to touch her right now, but he also didn't want her to think that he didn't want to touch her. So he forced conversation in a casual tone, trying to engage her in a topic that wasn't centered around her growth, to get her mind back on the right track.

With a sigh, he said "I'm sorry we couldn't get you to a better spot for this. If I hadn't gotten pulled over, you would have had time to find a better position. It's amazing you held on as long as you did." He smiled down at her, his eyebrows raised to show just how impressed he was.

"Mmmm, I know," she sighed, closing her eyes again. "By the end there, I didn't think I was gonna make it."

A few moments passed, and Adam filled the silence to keep her distracted. "I'm gonna have to make some small talk with the lady at the front office, when we go there for a shower. I think I might have been a bit rude to her when I checked in, since I was in such a rush."

"Mmmmm," was all Simone said. "Come here." Well, he couldn't refuse a direct request. Or perhaps a command. Either way, he stepped forward and gently embraced her again, carefully avoiding any sensitive areas as he wrapped his arms around her from behind. She didn't grow when he touched her, this time. Adam made himself more comfortable, pressing himself against her and nestling his head on her collarbone, as he liked to do. His face pressed against her warm breast, and he slowly breathed in and out through his nostrils, as the couple snuggled upright for another few minutes.

To be continued...
