Kelly walked back into her condo from getting the mail. It was a hot July day, and she dressed simply in a loose peasant tunic with a bandeau underneath and some booty shorts to show off her long legs. The day’s mail was mostly boring, bills and some bullshit offers about reducing student loan debt. The only intriguing thing was a small box with no return address. She opened it excitedly; sometimes her neighbors and other people around town sent her gifts for helping them with different things.

The only thing the box contained was a small bag of Japanese milk candies. Kelly had never had these before and was definitely interested in doing so. She examined the bag first, to make sure it was still sealed- you never know these days she thought. The bag looked fine to her, so Kelly quickly tore the bag open and popped one in her mouth.

She was surprised how great the candy tasted, savoring the flavor as she sucked on it. What Kelly didn’t notice was the effect the candy was having on her body. As she sucked and sucked, her small, perky breasts started to swell, filling out her bandeau more and more. As she finished the first one, Kelly impatiently stuck another candy on her mouth, ignoring the increased movement of her larger breasts, which now resembled grapefruit.

As Kelly sucked on the second candy, her boobs resumed growing. Her bandeau felt tight as her breasts grew too large for its recommended size, her nipples starting to rub against the fabric, getting stiffer as her tits grew. They approached the size of cantaloupes by the time Kelly had finished the second candy. She looked down for the bag of candies, eager to have another, when she finally noticed her growth.

“Oh my god!” She shouted. “How did my tits get so big? How did I not notice?” Kelly stuck her hands into her shirt and felt the heft of her new boobs. “These are definitely real,” she said. Kelly picked up the bag of candy when she saw it, suddenly curious. “Did the candy make my boobs grow? Is that possible?” She examined the bag all over, hoping for some kind of explanation. She had almost given up when she spotted the smallest text she had ever seen. Squinting, she read it. “May cause rapid breast growth and lactation in women.” That explains that, then, but… she felt her bandeau again discovered two small damp spots. Holy shit. I’m lactating. My boobs are actually full of milk…

Kelly looked at the bag again, then down at her breasts. “This is pretty hot, I have to admit… could I get bigger?” She tossed another candy in her mouth. “Might as well try, right?” Thinking, she pulled her shirt and bandeau off before they would get uncomfortable. Her huge tits wobbled as they fell out of her bandeau, occupying the space on Kelly’s rib cage as they finally came to a stop.

This time, she focused on her breasts as she sucked on the candy. The bulky spherical masses grew as the candy in her mouth shrank, taking up more and more space on Kelly’s torso. Her nipples continued to leak milk as they fattened up, although Kelly could tell she was producing more milk than she was expressing. Her burgeoning boobs began to dominate her figure as they relentlessly grew bigger and heavier.

Again, Kelly’s impatience struck as she stuck two more candies in her mouth, subconsciously wanting to turn herself into a huge-titted milk factory. She fell to her knees as the growth of her breasts quickened, her head-sized boobs rapidly approaching bigger sizes. The lower edge of her breasts crept past her belly button.

“I’m growing… so huge!” She said as her leaking nipples became beacons of pleasure. Kelly started to milk herself as her tits started to weigh her down. Her huge, growing breasts covered the floor in milk, still plumping up, still steadily growing larger and larger.

Kelly finished the candies in her mouth and felt her tits grow large enough to rest on her thighs. They showed no signs of stopping as the warm, heavy flesh covered more and more of her legs. The pleasure from expressing milk out of her fattening nipples kept increasing as well. It overwhelmed her, and Kelly fell back to lay on the floor as her breasts grew and spewed milk.

Kelly vaguely felt her breasts grow and cover her thighs, but it was hard to think of anything but all the milk pumping out of her tits. Finally, she felt the growth stop. She laid on the floor, slowly regaining her senses. She noticed how the floor around her was covered with her milk and how it soaked into her shorts and her hair.

She pulled herself up, slowly. First she rolled out from under her enormous boobs, then grabbed onto the counter she had left the bag of candy on. With all the strength she had, Kelly eventually stood, the immense weight of her tits pulling on her back.

Looking down, she was astounded by the sheer size of her tits. They were the size of beach balls, at least, hanging down almost to her knees. Her swollen nipples were two feet away from her chest, easy. The nubs looked hard and stiff as milk slowly dribbled out of then, big as shot glasses. Obviously her boobs were the widest part of her, extending about a foot past her hips on either side.

Kelly saw the bag of candies. Looking into it, it was still about half full. Her subconscious desires barrelled into the front of her mind, and she became aware of her wish to become truly huge, an immobile, lactating milk machine; more like a pair of breasts with a woman attached than the reverse. She thought about it for just a second before the tipped the edge of the bag into her mouth, letting the remaining candies fall onto her tongue.
