Stacy walked out of the shop with a contented smile on her face and slung her heavy shopping bag over her shoulder. She'd walked down this high street loads of times in the past, but she'd never been inside of the curious little corner shop before. It was odd, everything about it seemed so... plain. She had a vague memory of being surprised walking in there, but every second that passed that memory seemed to get further away, clouding over like it was covered in a thick layer of fog.
She shrugged her shoulders and walked on. The one thing she did remember about going in there was the reason, she was thirsty, incredibly so. She'd picked out an interesting looking bottle on the shelf. The liquid was a luscious-looking purple, and she had the vague memory of the shopkeep telling her that it was an excellent choice and that it was bound to bring her "Bountiful happiness", whatever that meant.
Stacy cast a glance back over her shoulder, trying to find the shop again, but she just couldn't pick it out. She shrugged and popped the cap from the bottle. It was a hot day outside, and she'd decided to wear a light blue cardigan over a thin top. She didn't have much of a figure to speak of, and she thought her choice of outfit would at least help her hide the lack of curves. She'd always wanted to have a more... outrageous figure, particularly in her boobs. She'd always hoped that she'd be a late bloomer, but nature seemed to have other plans for her.
She carried on walking down the street and took a deep swig from the bottle. The liquid was thick, and it wasn't exactly cooling, but it certainly hit the spot. But maybe not the one she was expecting.
She walked along the high street, looking in shop windows, fantasising about all the outfits she'd love to wear if she could pull them off. She felt a tightness in her chest and heat flushed her face and took another swig of her mysterious drink. She assumed it was a combination of her anxiety and the heat, and neglected to consider what else might be causing her rapidly rising body temperature. She carried on walking down the street, slowly sipping from the bottle as she went, hoping that the feeling of tightness would go away soon.
What she'd failed to notice was that the tightness wasn't coming from any anxiety attack, but real, genuine tightness. As she walked along, her shirt had slowly started to fill out. Her A-cup breasts had slowly started to swell, stretching the shirt she was wearing gradually. The more her chest swelled, the more sensitive it became. The more sensitive her chest became, the more Stacy's body temperature rose. The more her body temperature rose, the more she drank. Stacy noticed that more people were looking at her as she walked down the street. She hated being the centre of attention, and the way people were looking at her was only fueling her anxiety more. She took another swig as she carried on, hoping it was all in her mind.
She'd drank nearly a third of the bottle by now, and her tits were gaining ground rapidly. After the first few swigs she'd grown to a D-cup, but the more and more she drank, the faster they swelled. Her shirt had started to ride up her body, and the loose cardigan she wore barely managed to hang off her shoulders as her ballooning breasts claimed more and more of her torso. Stacy still hadn't noticed, her attention focussed on anywhere but herself. If she had, she might have noticed that her nipples were making an admirable attempt to burst free from their confines. If she could have seen them. They'd grown so far away from her at this point that identifying the dents they were making in her shirt would have required her to pull them up to her own face.
More staring. Stacy could barely handle it. She started to rush, desperate to make it to the train station so as to finally get some shelter from the oddly rapturous attention that people were paying to her. This didn't help. She'd never needed a bra, and her newly endowed body was taking full advantage of the situation. Her massive tits bounced as she powerwalked down the streets, gaining more and more attention the faster she walked. The more they bounced, the closer they came to freedom; but also the more tired Stacy became. Her obliviousness to her new body didn't stop her from becoming tired, so she took another deep swig from the bottle, draining another third of it in one go.
Her tits swelled out more, claiming as much of the strained shirt as they could, before finding more places they can expand to. The neckline of her shirt had been stretched out so much by her new enormous sweater puppies that it gave enough room for them to start swelling over the top. Stacy's cleavage squeezed beyond its fabric boundaries, creating a tight, meaty valley that slowly crept up to her chin and slowly invaded her line of sight. Down below, her shirt continued to ride up, displaying a beautiful abundance of underboob to any passerby as her titties started to cover her stomach in their fleshy bountifulness.
Stacy felt a brief moment of relief before the tension returned.
