As Adam spun the top onto his metal water bottle, Simone turned towards him, her green eyes twinkling as they looked up at him. Her eyebrows raised when she saw him frowning. "What?" she asked as a smile broke out on her face.

He couldn't stop from cracking his own smile as he saw the shit-eating grin on her face. She knew she'd been busted, alright. He smiled, but his eyebrows rose warningly as he said, "Don't think I don't know what you're doing, here."

Simone's mouth dropped open, but she couldn't keep her smile from ruining her shocked expression. "Why, Adam, I don't know what you could be talking about."

Adam rolled his eyes, but didn't say anything. He just crossed his arms and leaned at an angle, looking down and widening his eyes as if to say "Seriously?" and he held up the map, giving it a little shake for emphasis.

Simone laughed, dropping the facade. "Ugh, fine," she said, stamping her foot on the rocks. Then she stepped closer to Adam slowly. He straightened up as she reached him, looking over her head at nothing. "You caught me," said Simone huskily as she leaned her head back, looking up at Adam from his chest. He had his arms crossed, so she bumped her boobs into his elbows. He quickly lowered his arms and put his hands on his hips, still stubbornly looking off into the distance. Simone pressed into him, her body warm from the hike. Where their arms brushed against each other, both their sweat caused their skin to stick a little.

"Babe?" Simone asked below him, trying to get his attention. He turned his head side to side, still not looking down at her. He felt her mashing her own chest into his as she slowly bounced against him, chuckling at his antics. Am I imagining it, or does her chest feel...

"Baaaaabe..." Simone said seductively, and he couldn't help but glance down. Her boobs had swelled inside her tank top, bulging upwards and against his chest. Her white camisole had a high cut, so he didn't see much cleavage, but the little glimpse he got of it was deep. Adam felt his dick pulse in his shorts.

He immediately turned his head and stepped away from her, crossing his arms again. Not this time, he thought, his anger keeping his libido under control.

Simone scoffed behind him. "Honey, what's the problem?" she asked, stepping up beside him. Her soft boob pressed into his elbow as she tried to get him to look at her.

Adam glanced down. Her eyes seemed wide and sincere. She really didn't see why he was mad. "You tricked me," he grumbled, then looked away again.

Simone sighed, and looked down at the ground for a few seconds. Or maybe at her chest. "I know. I'm sorry, Adam. I guess I just -"

"I thought we could just, you know, go for a hike today!" he blurted out suddenly, surprising himself with his own volume. Simone flinched backward as well, for a moment. He took a deep breath and lowered his voice, but his anger still came through. "I didn't... I didn't want this week to JUST be about you growing bigger, Simone," he said, looking down at her. "I wanted it to be about us. I thought we could just have a good time together, doing -" he almost said "doing NORMAL things!" just then, but he knew how she'd react to that word. "-doing things that don't revolve around sex," he finished, raising his hands in frustration. His right arm ran into her breast though, so he gestured with his left.

"But babe," she said, leaning against him and resting her head on his chest. He let her do that, even though it meant her boob was brushing his elbow again. It looked like she'd stopped growing, for now, but her breasts were still straining her top. "We do stuff together all the time. We hardly ever have sex."

She had him, there. He sighed. "I know. I know we don't have enough sex. It doesn't make for a... healthy relationship." he said. He clenched his jaw as he went on. "I wish we could do it every day, Simone. You know how much I love it when you get bigger," he said, wrapping his arm around her as she leaned into a half hug. "But you just... don't fit in most places, anymore, honey. I'm..." his voice got hoarse suddenly as his throat tightened with concern. "I'm worried about what will happen if you keep growing. What if you break something, or hurt someone? Simone - what if you hurt yourself?" he asked, his words coming out quicker. "What if you're in a car, or on a bus, or something, and you can't control them? What if-"

"Adam, baby," she said soothingly, as she wrapped her arms around him fully and hugged him tight. "You don't have to worry about it." He looked down at her, his eyebrows arched in concern, but she was totally calm. "Adam," she said with a smile. "I have complete control over the size of my boobs. It's only when I'm around you that I have trouble keeping them contained."

He blinked down at her. In all the time he'd known her, she'd never described her condition this way. He'd thought it was a constant battle for her to maintain her concentration, even when he wasn't around. "Do you... really mean that?" he asked, his expression troubled.

"Of course," she said, swaying against him slowly. "When you're not around, when I'm at work... it's like I forget I even have these things." She pressed her breasts into him, and they swelled a little more. Simone was trying to make him feel better, but she was achieving the exact opposite. Adam's heart was racing, his mouth dry all of a sudden. He didn't want to tell her what he was thinking. But he had to. It wasn't fair to her, to keep her in the dark about his real opinion.

"Simone, I..." he said hoarsely, and cleared his throat. He looked off into the tree line as he tried to find the words. His chest felt tight, and he started sweating again. You have to tell her, he thought miserably.

Taking a deep breath, Adam looked down at her again. "Honey, don't you see?" he asked quietly. Simone tilted her head, and her eyes narrowed in confusion. "Simone... if I'm the one who's affecting you like this, then..." Spit it out, man! "...then maybe we shouldn't be together at all." He choked on the words as they came out, and immediately felt his eyes begin to tear up.

Simone eyes widened. She broke her embrace and took a step back from him, her mouth dropping open in a stunned expression. Her jaw worked for a few moments. Then in a quiet voice, she said, "You don't mean that."

Adam just stared at her. He truly didn't know what to say. But the words were out of his mouth, now.

This was going all wrong. It wasn't supposed to happen like this. Only the second day of their week-long trip, and he'd blurted out the thing that had been on his mind for so long. The one thing that he couldn't take back. Why did she have to lie? he thought bitterly. Why couldn't we just have a nice hike together?

The couple maintained eye contact, and Simone's eyes darted back and forth in panic as they scanned Adam's face for sincerity. His heart was breaking, but he couldn't take back his words. He meant what he said.

"Oh my god," she said, exhaling hard. "You're serious. You really want to break up." She inhaled again as she looked away from him, then quickly exhaled again. Her face had become pale. She grasped her stomach with both hands, looking like she was about to be sick.

"Simone?" Adam asked, suddenly worried. He stepped forward, but she immediately recoiled from him, looking up at him as if he was a stranger to her.

"Don't -!" she said, starting to hyperventilate. "Oh god, I can't... I can't breathe." She looked down at her chest suddenly, and her hands came up to grab her boobs. They were already tightly packed inside her tank top, and now they began to rapidly swell larger.

"Oh shit," said Adam as he stepped towards her again. "Honey, I'm so sorry. Let... let me help." Simone was holding her breasts as they grew bigger, breathing in and out in sharp, short gasps. She was in shock, Adam realized. Her concentration was broken, and she was going to grow to full size. Adam stood in front of her and gripped the bottom of her shirt, gently raising it upwards.

Simone looked up at him with wild eyes, but she lifted her arms up and let him pull her tank top and camisole up. The hem stretched as it came to her chest, but he managed to get it past her swelling bosom, up over her head. She took a staggering step backwards away from him, yanking her arms out from the shirt before he could finish taking it off. As she stepped back, she tripped on a bump jutting up from the rock, and fell onto her ass.

She managed to break her fall with her hands, but the black sports bra she was wearing couldn't handle the sudden impact from breasts it was never meant to contain. The garment tore open in the middle, and Simone's growing tits sprang out, already the size of basketballs. Still hyperventilating, Simone watched with wide eyes as her boobs grew bigger and bigger.

Adam watched too, standing a few feet away, holding Simone's shirts in his hand. He wanted to help her somehow, but what could he do? She'd just said that he was the one affecting her. "Should I... should I leave?" he asked.

Simone jerked her gaze up towards him. "No!" she said incredulously, as if that was the exact wrong thing for him to suggest. Then: "HUUUUUNNNNHHHH!!" she yelled, as her breasts surged outward, filling her lap to overflowing. She was still trying to talk, in between moans. "Don't - HUUHHHHHH!!" her tits grew bigger again, swelling to the size of bean bag chairs. "Don't leave me!" she finished desperately, and Adam could see her eyes were filling with tears.

He couldn't tell if she meant not to leave her right now, or if it was a plea to not break up. Either way, he stayed put, only backing away as her breasts started growing into his space. Adam had never seen her so emotional before. And he'd never seen her lose control of her breasts quite like this. Unlike other times, she didn't seem to want to be growing - rather, her emotions were preventing her from keeping herself contained.

Adam found that he wasn't aroused right now, either. His own scattered emotions were still reeling from his own revelation, and right now, Simone's growth wasn't something he was enjoying. I did this to her, he thought, disgusted with himself. He'd been responsible for her growing so big, and now it was his fault she was so upset. He regretted telling her that they should break up, but at the same time, he wondered if perhaps this was the best place for this to happen. The clearing they were in had plenty of space, after all.

"HUNHHH!" Simone grunted, her breasts swelling bigger than tractor tires. Adam couldn't see her over them anymore, where she was sitting. He suddenly realized that her legs were probably pinned underneath her boobs, and began to circle around her to help. "HUHHHHHH!!!!" she moaned again, and they grew, now as big as cars.

As he came around behind her, Adam saw Simone leaning back on her hands, her head tilted backwards and her hair resting on the ground. Her eyes were closed as her breasts swelled in fits and starts. Her broken bra had fallen down from her shoulders and now rested around her elbows. "Simone, here," Adam said as he reached her. "Let me get you up."

She opened her eyes and looked at him coldly, but she allowed him to grab her under her armpits to pull her out from underneath herself. As soon as he touched her, though - "GUHHH!" she exclaimed, and her breasts surged outward again, even faster than before. Adam tried to move quickly, scooting her backwards from under the soft mountain of flesh, until her legs could get free. "UUHHHHHHH!" she yelled again, as she managed to stagger to her feet. Her boobs now rose above them, their peaks climbing higher and higher into the sky. She could already stand up straight, and she leaned into her cleavage as she swelled.

Adam let go of her as soon as was standing, but as he tried to step back, Simone twisted and flung a hand out behind her, grasping Adam's forearm. "No!" she said desperately "Don't leave me, babe. Make me - UHHHHHH!" Another surge of growth. "Make me bigger," she panted. "Please." The hunger was back in her eyes, and they shone green and bright, reflecting the sunshine. But her expression was even more carnal and twisted than normal, brimming with urgency.

"UNNNNNHHHH!" she moaned again, as she grew bigger. Her creamy flesh, dotted with freckles here and there, rose further above them.

Adam couldn't tell how big they were, anymore. He couldn't see anything past them. It was just him and Simone, and her colossal boobs. Nobody around to witness them, nothing that she could damage with her growth. It was everything he'd wanted. Just fuck her already, his caveman brain urged.

But he couldn't do it. The swirl of emotions he felt kept his cock from getting hard, true - but that could easily be remedied, if he just decided to strip naked, and get closer to her. He knew he could be hard in moments. But it would be wrong. As much as he wanted this - as much as Simone wanted it - he couldn't do it anymore. It was too much, and for both their sakes, he had to stop. Slowly, deliberately, he reached his other hand over, and peeled Simone's fingers off his arm, as he stepped away.

"NO!" Simone screamed. "UNNNHHH!" she swelled with growth again, flailing her hands around behind her, twisting back and forth to reach Adam. She couldn't reach him though, and her breasts were far too heavy to budge even an inch. "Babe! Please! PLEASE! UHHHHHHHH!"

Another surge of growth. But this one didn't seem so powerful as the last one. Adam continued to slowly step back, still holding Simone's shirts. "No! she yelled again, this time facing forward, throwing her arms out wide against her breasts. "Don't stop! HUNNNNNHHH!! Don't stop growing!" she shouted at her boobs. But despite continuing to swell bigger and bigger, her growth was slowing down. And this time, Adam wasn't around to provide the push for a final explosion of growth.

It didn't stop Simone from trying to replicate it, though - she snaked her hand down below her waist, and he watched her elbow working furiously as she pleasured herself. "HUUUUHHHHHHHH!!!" she groaned, her body bucking against her breasts, as they swelled larger again. But despite her continuing with her hands for several minutes, that was as big as she could go. Eventually, she collapsed against herself, and after a few moments, Adam heard her sobbing.

He was about 50 paces away now, and he'd grabbed both their backpacks. He felt terrible for how this day was going. It was amazing how quickly he'd gone from feeling so hopeful about their relationship, enjoying a nice hike with his girlfriend. He'd thought Simone was enjoying it too. But really, it was just another excuse to grow bigger. Adam felt miserable about ruining her day, and the sobs that drifted across the clearing were like nails on a chalkboard, to him. He couldn't stand to see her in such pain.

Despite her anguish triggering his feelings of empathy, however, Adam felt another emotion that was growing stronger by the second - pity. Simone was truly addicted to growing bigger, and it pained him to realize that she'd fallen so far into that addiction.

This wasn't her. She was so much better than this. Where was the calm, collected Simone that he saw every day? The one he'd fallen in love with? And he was partially to blame for leading her down the path of addiction- his own fantasies about her growth had been fueling her, this whole time. He didn't expect her to ever forgive him for abandoning her, and neither did he think he'd ever be able to forgive himself, for letting it go this far.

Adam waited patiently while Simone's sobbing slowly wound down, until finally, she fell silent. Then he walked over to her. As he approached her from behind, she turned her head toward him, rubbing her nose and sniffing. The edges of her eyes were red.

"Adam, please," she said softly. "I want to be bigger. I want to grow bigger for you," she pleaded, a crooked smile creeping onto her face. Her breasts shuddered again briefly, and swelled out a bit more.

He took a step back, shaking his head. "I'm sorry, Simone," he said quietly.

"Please, babe," she begged. "Just fuck me, one more time. Make me bigger." She threw her arms out against her breasts again, arching her back as an invitation.

"I said, no." Adam crossed his arms, and stood there until silently. She pleaded with him some more - it unfortunately sounded rather pathetic. But none of it was enough to change Adam's mind.

Eventually, she gave in, and after some time, she began the long process of shrinking her breasts back down to their usual size.

Epilogue

The whole hike back to the car, Simone didn't say a word to Adam. As soon as they got in, she spoke up. "I want to go home."

Adam was quiet for a few moments as he pulled out onto the road. "Can we pack up the campsite, f-"

"NOW." Simone commanded, and her breasts suddenly bulged out into her tank-top again, swelling larger.

"Okay, okay," Adam said, his eyes widening at how fast they were growing. She really was in no mood to argue, and he wouldn't put it past her to destroy his car to make a point. He drove straight past the campground, telling himself that he'd drive back out here and collect the tent later. Maybe he could even stay there the rest of the week, or at least a few more days, to give Simone time to cool down. And move out.

I can't believe we're really breaking up, he thought, as he drove down the winding mountain backroads. Simone had been such an important part of his world, for so long. He really had thought they'd be spending the rest of their lives together. In the end, though, he cared about her too much to stay with her. Painful as it was, it was for the best.

The couple was completely silent the entire 3-hour drive back to the apartment. At least there was no traffic.
