Fit to Burst

A young girl has a special power over her body. And she loves to amuse herself with it.

She practically skipped down the road towards her home, not caring who saw her. She was more excited than she had been in days, and why shouldn't she? Work was finished for the week, and she had no obligations to fulfil and no one to visit. She would be alone to spend the time indulging in her secret hobby...

She giggled and looked down at the Oxfam bag she was carrying. She went to the local store so often to buy ‘items’ she needed that the staff were always ready to recommend stuff to her. And it was nice to know she was giving old clothing which would have sat in a dusty box for years a final use, and helping some poverty-stricken people at the same time. And it was cheap. Everyone won, including her.

She raced into her small house, bolting the door and heading straight to her bedroom. Normally she would relax on the couch with a drink and watch some TV first, but after a long day at work, she knew what would be more enjoyable. And she was hardly willing to wait.

In her bedroom, she took a moment to close the curtains, then happily leapt onto her bed, laughing as she bounced on the mattress. Settling down, she then sat up and removed her clothing, throwing them into the corner.

As her panties were flung over to join the pile, she spotted the full-length mirror fixed to her closet door, and turned to look at herself.

As much as she liked her body, she was proud enough to admit that her appearance, though considered pretty by many people, was fairly unremarkable. Long brown hair framing her face, her body an average build, nice sizable breasts, curved hips and a slight potbelly. Nice, but nothing special. She could easily blend into a crowd and no one would take special notice.

She smirked, amused by the knowledge that her body was more remarkable than anyone could imagine. And with a little thought, she would definitely stand out from any crowd. But first things first...

She grabbed the Oxfam bag and emptied the contents out before her. A variety of clothing and underwear piled up, and she began pawing through the pile to pick out ones she liked.

The first item to be put on was a bra, a nice simple blue one which was a cup size larger than her C-Cup chest. She always chose items a little bigger than her size. Next was a stretchy pair of cotton leggings, which hugged her legs and hips. Finally, she put on a large white blouse, making sure to button it all the way down.

She grabbed her mobile phone from the side table and turned to the mirror again. She then put on a sexy pose and snapped a picture of her reflection on the phone. It was always fun to get before and after shots. Maybe she would show the collection she had built up to someone one day...

She pushed that thought aside. It was time to get to it. She was shivering with excitement as she settled herself against the backrest of her bed, back against the wall. She willed herself to calm down, taking deep breaths.

When she felt ready, she closed her eyes, and began to concentrate.

Over the years it had gotten easier to work this strange power of hers, to simply will herself to change. Already she could feel the warmth in her chest and legs, as if she was immersed in warm water. Another minute passed, and then she felt it. The fabric of the bra, once loose, was now pulled taut as her breasts pressed against it. She could also feel the elastic waist band of the leggings shift on her hips slightly. Smiling widely, she opened her eyes, sat up onto her knees, and looked down.

Her breasts were noticeably larger, pressing out underneath the shirt and drawing it taut against her body. Slowly they grew, their shape standing out more as she filled out the loose shirt. She cupped her chest with her hands, using her fingers to gauge the size they were. Normally they fit in her hands neatly, but now the soft flesh was more than a handful, beginning to overflow her fingers. She could feel the bra getting tighter, the cup’s fabric stretching as it tried to contain her.

One hand remained at her breast, the other travelled down to rest on her thigh. Immediately she could feel the difference. Her thighs and hips were also growing, steadily becoming thicker and softer. Her fingertips trailed across her skin from her thigh to her bottom. She could tell from feeling that her bum was larger, the leggings stretching to contain her new size. One finger pressed into the soft flesh, and she marvelled at how pliable, yet firm, her growing shape was.

She let this continue, holding her concentration while she rubbed her breasts and bottom, savouring the sensations as her flesh pressed against her hands and her clothing got ever tighter.

Moments later, she could hear the sound of the threads holding the blouse's buttons straining to give, and took that as a sign to stop momentarily. Sighing, she broke off her concentration, then turned and sat at the edge of the bed, facing the mirror to admire her handiwork.

Her breasts were huge, standing far out from her chest and straining the buttons of the blouse. Wide gaps between each of the buttons allowed her to see her bare skin underneath, and the straining bra, cutting into the soft flesh. Her hands attempted to cup her chests, but they were far too big for her hands to handle. She could compare them to the size of overgrown honeydew melons. Thankfully, for some reason she had never figured out about her power, they were not as heavy as actual melons. There was weight in her breasts, but not enough that they were uncomfortable.

Her hands trailed down her body, running along her still slim waist and towards her hips. They touched them earlier than expected, as they were now much wider, sticking out father than the width of her torso. Her hands rubbed her smooth hips before shifting back to press into her expanded bottom. Both her cheeks were huge, sticking far out, and she could feel her leggings straining to stretch and cover the expanded area.

As she did a few poses for the mirror, she could feel how tight her clothing was around her now. That feeling or snugness, of fabric tight against her skin, of her body trying to push out while being held back, was one the things she adored about this little exercise of hers. She settled back onto the bed, and for a few moments she was content to just lay back and caress her body, her hands stroking and pressing her soft curves, creating a pleasant sensation within her.

She knew this was merely a teaser though. After she got tired of touching, she sat up and swung her legs over the side of the bed, so that she was facing the mirror.

She took a deep breath to ready herself, sitting upright and placing her hands to either side of her waist, taking sure to hold the bottom of the shirt against her lower half. She tingled with excitement as she stared at her reflection, focusing on her chest. A few more deep breaths, then she closed her eyes and began to concentrate. The warmth within her returned, and she opened her eyes just in time to see her breasts start to grow again.

Slowly but steadily they grew larger, expanding like rising bread dough, the front sides inching farther away from her chest. Her shirt and bra grew tighter as they tried to contain the growing masses, and she began to breathe in short gasps as the tight, snug feel around her body became greater. Confined by the blouse, her breasts began to expand in every direction, filling as much free space within the garment as they could. She felt a slight twinge as her soft flesh squeezed out from beneath the underwire of the bra, and began to overflow the top of the cups. Glancing down, she could see the breasts bulge out of the space beneath the shirt's collar, revealing several inches of cleavage. She was tempted to reach around her swollen chest to gauge their size, she he was still holding tightly on the lower half of her shirt, making sure it didn't billow out as her chest grew.

Not that it mattered much, as the blouse wouldn't hold much longer. She could see the shirt's higher buttons straining to the last, the gaps between them considerably larger. The threads attaching the buttons and the seams of the shirt itself were creaking, loud enough that anyone who happened to be nearby would have heard them from across the room.

The blouse was on its last legs and yet still she focused, feeling her breasts swell larger and larger. The strain on her buttons was reaching critical mass when…

POP! The button at the center of her bust line burst off, the pressure sending it flying across the room and into the wall at top speed. She watched the button's path as it bounced off the wall, then spotted another button flying behind it, as if to catch up.

As the restraints began to weaken, her breasts surged forward, buttons flying off in rapid succession. The sound of threads popping one after the other reminded her of machine gun fire. In her head, she conjured up the funny mental image of her surrounded by a gang of thugs straight from a comic book, the buttons knocking out the foes as her breasts expanded with funny sound effects as they collapsed in a heap. She giggled at the thought. As fun as her power was, it wasn't exactly practical for crime fighting.

She returned her attention to the blouse, which had just lost the last button in its bodice area. With nothing to hold them back, her breasts pushed the upper sides of the garment beside, finally standing out free, save for her tight bra. But she wasn't done with the blouse yet. The lower buttons were still unharmed, and she had plans to turn them into miniature artillery too. This would be easier, she just needed to change her focus.

She leant backwards, using one arm to support herself, and the other to hold her expanded breasts down against her chest, so as not to block her view. This was a tricky task, considering that they were so large she could barely get her arms around them. She would gauge their size later, but first things first...

Once she was satisfied, and she could see the remaining buttons clearly, she began to focus, this time willing another part of her to grow. The warmth returned, this time within her belly.

Watching her reflection, she grinned as she saw the blouse billow out once again, this time by her belly. She could feel it expand, the soft flesh speading out and forwards as it was confined by the blouse. It rounded out into a full curve, drawing the fabric tighter, the buttons straining like their brethren before. A few more inches, the fabric squeezing her tighter, then... POP POP POP!

The remaining buttons flew off and joined their friends on the floor. Her shirt was now wide, open, and she removed the ruined garment and dropped it to the floor. She stood up to admire herself, impressed by the figure she had become.

Starting from the bottom, her slim calves led up to thick smooth thighs, flaring out into her wide hips. Turning slightly, she could see her fattened bottom sticking out proudly, the leggings hugging her curves for dear life. Her gaze moved up to her soft belly, the small potbelly swollen from its original size into a volleyball sized dome which curved gently away from her body. One could assume she was five months pregnant from its size. She rubbed around its circumference, feeling a small maternal twinge as she caressed her round belly.

As large as her belly was, it was overshadowed by the breasts above it. Each one was now the size of a basketball, obscuring most of her torso as they rested on the apex of her belly. They stuck out about a foot from her chest, but they would have protruded more if it were not for her bra. Miraculously, the bra was still intact, but stretched and strained to the absolute limit. The underwire of the cups had silently snapped ages ago, leaving the material to be pulled flat against her breasts. Each cup now only covered her nipples, and indented her skin as they were pulled in all directions by the straps supporting them. The straps had stretched as much as they could, but they were now pulled taut as they tried to restrain her chest.

Smiling, she grabbed her phone and snapped a picture. This was definitely one for the collection.

She gently placed her hands on her breasts and gingerly stroked them, making careful movements so as not to place too much pressure on the bra. She caressed the sides, tops and bottoms of her massive orbs, every so often grabbing a handful of soft flesh and giving it a gentle squeeze. And there was so much to squeeze. It was like holding a pillow to your chest, except you could feel the sensation of your hands pressing into your body.

Everywhere felt so tight. The bra straps pressing into her flesh, the leggings hugging her massive thighs. With every breath she could feel her chest push against the restrains and release, before pushing back again. The sensation of being compressed, her body urging to burst free and expand again...

She didn't know why she liked this feeling so much. But it excited her like nothing else could.

As she lay down on the bed, hands roaming all over her body to feel her new curves, she acknowledged that there was a lot about this power she didn’t understand. How she did it was a complete mystery. She'd gone to a doctor and discreetly mentioned she had a problem with 'swelling' in her chest, (she was nervous about being discovered and being turned into some sort of science project.) but an examination had revealed nothing strange about her body. No weird DNA or chemical changes, no mystic aura.. she just concentrated, and she swelled up. For a while, she had imagined it was some sort of psychic power, using her will to change herself. But surely there was more to it than that. Sheer will couldn't just change a person's shape. There was something within her, some strange force beyond anything mankind could comprehend...

But did it really matter how and why? As far as she knew, this power was only capable of giving her bigger curves. And as long as it only went as far as that, why worry about it so much? This was something private, something special only she could enjoy.

She wrapped her arms around her breasts, barely managing to get around their full circumference, and squeezed them into her chest. A long sigh escaped her as the sensations of her pressed flesh washed over her.

She glanced over and stared at the other side of her bed, empty and undisturbed. She gave another sigh, this one a little sadder. As much as she liked having this power to herself, sometimes she wondered what would happen if she shared this secret with someone else. Her friends, or perhaps a man she liked. What would they think? Would they be amazed or repulsed? Would someone admire her expanded body, and would want to touch her like she touched herself? Maybe go a little further...

Her cheeks heated up at that thought. She'd been thinking more along those lines lately.

Maybe someday she would work up the courage to share her power with someone.

Smiling wistfully, she sat up and thrust her chest out, feeling the bra straps tighten as she moved. There was still some hold in the stretched garment. Reaching over carefully, she grabbed her wristwatch from the side table.

Setting the digital timer to its stopwatch mode, she held it before her, ready to start sthe clock.

She closed her eyes and began to concentrate. Almost instantly this time, she felt her breasts swell again. They slowly grew larger, the bra creaking ominously as it tried to hold them in.

She smiled to herself as she opened her eyes and watched the stopwatch clock up the growth of her chest.

One day she would share this power. But she had all the time in the world to do so. Until then, this was just hers to play with.

And right now, it was time see how fast she could bust this bra of her chest.

She grinned in determination. Maybe she could beat her personal best today.
