Aoi Asahina strolled through the door of her home. She was coming back from a bakery, having purchased her favorite: donuts. The lifeblood of humanity, she thought cheerfully. Aoi placed the boxes on the kitchen counter and leaned against the edge of the counter, her butt pressing into the granite. After taking her jacket off, she opened the box, gleefully eyeing the pastries contained within. I probably shouldn’t eat all of these now… well… one can’t hurt. The busty woman picked up a donut with one hand, brushing a lock of brown hair behind her ear with the other. She took a bite, savoring the flavor of the fried dough and icing. Aoi didn’t notice, however, how her chest bulged out subtly a few seconds after she swallowed.

“So good,” Aoi mumbled as she stuffed another bite of donut into her mouth. The busty young woman was fully enraptured in the flavor of the donuts and she still didn’t realize she was becoming more endowed with each swallow. She finished the first one, her bosom now pressing forcefully into her bra cups. Aoi licked the leftover icing from her fingers, the small remnant of a donut pushing her bust out ever so slightly. She looked longingly at the mostly-full box, her love of donuts overcoming her sense. “I don’t even feel that full, so I might as well have another one,” she reasoned. “I’ll just have to swim even more this week than usual to work off these sweets.”

She took a large bite of the second pastry, her mouth stuff full of fried dough. Aoi ate and ate, her breasts growing and growing, not realizing something was happening to her until one of the buttons shot off her blouse. She quickly licked the icing off her hands before investigating her shirt.

“Oh my gosh!” she exclaimed. “What happened?” Aoi pressed her hands around the new hole in the front of her shirt and finally noticed her increased bust size. “Woah!” She felt how her boobs were mushrooming over the tops of her bra cups and underneath the bottoms of them. “These are huge! How’d they get so big?” Intrigued, Aoi unbuttoned the remaining buttons on her blouse and took the shirt off, revealing her vastly overtaxed bra. She tried to unhook the back of her bra, to no avail. The pressure from her huge breasts made the band too tight for her to make the clasp budge. Perplexed, she absentmindedly picked up the last piece of her third donut. Swallowing, she felt her boobs bulge even more into her too-small bra. “The donuts! They’re making me bigger!”

I’ve got to stop eating them, she thought. But her desire for more was overwhelming. “Just one more can’t hurt, right?” She picked up another donut, her fourth, and quickly devoured it, flesh pouring into her already huge breasts. The band around her chest tightened, restricting her breathing. Aoi picked up another, and finished it as fast as the fourth. The growth pushed her bra past it’s breaking point, and the useless garment flew off her chest, freeing her cramped boobs. They bounded out into the space now available to them, assuming a more natural, tear-drop shape. Aoi held her boobs in her hands, marveling at their new size. “I’m so big! The donuts are making my breasts blow up,” she mumbled as she took another bite of a donut, her breasts surging bigger, reaching her belly button now. Her tits ballooned as she unthinkingly at more and more, somehow not feeling full. As she ate, Aoi’s head-sized boobs swelled larger and larger, growing to astounding sizes, rapidly surpassing her hips.

As they grew, Aoi picked up the boxes of donuts and knelt on the ground, resting her heavy boobs on the floor to give her back a break. She placed one box on either side of her tits, now grabbing donuts with both hands and stuffing them into her mouth, not caring that she was making her boobs grow to impractical sizes. She happily ate more and more donuts, not paying attention as her breasts grew and crept across the floor, spreading out in front of her. She quickly finished the initial box and focused her attention on the second, placing it on top of her huge, beach ball-sized boobs. As she ate, icing dropped from the donuts into her cleavage. Aoi used one hand to collect as much of the icing as she could, sticking her fingers in her mouth between bites to clean them.

Her breasts kept growing, and she plopped onto her butt as they swelled out in front of her, her legs to either side of her boobs. Finishing the second box, Aoi remembered she had a third still on the counter. She slowly dragged herself and her massive tits to reach her prize, and pulled it down off the counter, resting the box on top of her breasts again. She rapaciously dove into the box, munching down pastry with exceptional alacrity. Aoi’s boobs followed suit, still growing bigger and bigger, reaching an absurd size. The only thing that stopped Aoi from eating more donuts was running out of them. Sitting on the floor, she leaned against the counter. She couldn’t see much beyond the horizon of her colossal breasts.

Her hugely swelled nipples were near on five feet away from her chest, the space between them composed entirely of breast. Her boobs were each individually three feet wide, too huge for Aoi to move. They were bigger than those huge beanbag chairs she remembered seeing around in stores.

Aoi examined all the empty boxes around her. “I wish I had more donuts,” she complained.
