Karen sat in her cubicle at work. It was late. She was tired. She was pulling yet another late night tonight, the frustration eased only by the presence of her best friend in the cubicle over. Karen was just trying to get all of her files from this month organized so her quarterly report would be easier to create. She glanced at the clock on her computer screen and rubbed her eyes, as if that would make them less dry and tired. Nine thirty-four, it said.

Karen relaxed and laid back in her chair, letting her head hang over the back of the chair. Her blonde curls tumbled away from her face as she started at the ceiling. When she sat forward again and focused her eyes on the screen she saw something that shouldn’t have been there. A pop up ad for what looked like a porn website. There weren’t any scantily clad women, just a single phase in garish design. “Hot, busty, milky babes are waiting for YOU to join them!” it said. The pop up had only one button on it, “Join.” There wasn’t even the red X in the corner. Annoyed, hoping whatever website came up would go away quickly, she clicked “Join.”

Surprisingly, nothing else appeared on her screen. The pop up vanished, leaving just Karen’s spreadsheets and text documents open. She chalked it up to just having a strange day. She heard Stacy from the other side of the divider. “I’m going to make some coffee, you want any?"

“Uhh… sure. Why not? You know how I take it.”

“I think only Kyle knows that information,” her friend teased, “but I know how you like your coffee.”

Karen rolled her eyes at Stacy’s terrible jokes. They were always bad, but they had taken on their own humor in Karen’s opinion. Like they were funny because of how bad they were. Forcing herself to concentrate again, Karen started back on her work. She was totally unaware of what that pop up was now doing to her: by “join” it had meant “join the ranks of these hot, busty, milky babes,” not to physically meet them like so many of those kinds of ads implied. By clicking “join” she had unknowingly agreed to grow bigger boobs and start lactating. The process has already started and Karen, dressed in a loose-fitting blouse, didn’t notice.

As her breasts began to swell, the magic of the pop up made her bra fade away discretely. Karen’s orange-sized breasts grew quickly enough to be noticeable by another person but slowly enough that Karen herself remained unaware. They pushed out, not yet making contact with her shirt. Her nipples stiffened in the chilly office air. Karen’s boobs continued to grow as she typed away unwittingly, passing through cup sizes, not showing any indication of stopping soon.

Karen was vaguely aware of Stacy leaving her coffee on her desk. It seemed hard to focus on anything right now. Inside her shirt, her boobs plumped up happily, gaining weight and size. If her bra hadn’t vanished, it surely would have been noticeably too small for her grapefruit sized breasts. As she grew bigger tits, they eventually made contact with her blouse. Karen’s shirt tightened as her breasts took up more and more space inside it. She was still oblivious to the changes even now.

Damn shirt must’ve shrank in the wash, she thought. Her hard nipples slowly dragged across her shirt as her boobs grew, subtly arousing her. Karen moved her arms to rest her head in her hands and was surprised to feel her biceps pushing into her breasts much earlier than she expected. She looked down, startled. “Oh my god!” she shouted. Now that she had noticed the growth, it seemed to pick up, her breasts rapidly growing larger than cantaloupes.

Karen’s breasts grew and grew, putting enough pressure on her blouse to pop off two buttons, exposing her mounting cleavage. She quickly stood and ran to the bathroom, holding her burgeoning boobs in her hands as they steadily swelled. Stacy poked her head over the divider after Karen left her cubicle, just in time to see her friend reach the bathroom. Must’ve been holding it in too long, she thought as she resumed her work.

Inside the bathroom, Karen’s heart was beating out of her chest. “Where did these things come from?” she asked to no one as her tits pushed the last button off her blouse. Freed from their confines, Karen stared down incredulously at her huge breasts. They were preposterously large, covering half her torso, and still getting bigger. Karen’s head sized breasts were capped by plump pink nipples, ones larger than she was used to seeing.

Karen stared into a mirror at her growing boobs as they began to firm up. They felt full, and as she watched a thin white liquid began to leak from her nipples. The liquid fell from her nipples in drops into the sink in front of her. She touched her fingers to a nipple and tasted the liquid. “It’s… milk,” she said. “As if this couldn’t get any weirder.” Her milk flow strengthened, the drips turning into a thin stream. Karen noticed that her nipples–which had continued to grow with her boobs–felt the slightest bit pleasurable. She had a momentary thought, and brought her hands to her fattening nipples. Manipulating her breasts, Karen sought to make her milk flow more quickly. Almost as if they sensed it, her lactation intensified and Karen’s boobs grew more quickly, surging past volleyball sized, growing rapidly towards torso-dominating.

Karen’s huge tits weighed her down, and she knelt on the floor as they grew and grew. Karen’s breasts continued to pump milk, the streams now shooting out nearly a foot from her nipples. She focused solely on the milk flowing through her thick nipples, not caring that the floor was getting covered. Somewhere in the back of her mind, Karen wondered if her boobs would ever stop growing. She wasn’t sure she wanted them to. Karen’s gargantuan tits grew large enough that they hung over her knees, still swelling bigger even then. Her nipples hardened when her boobs touched the cold tile floor, causing her milk to start shooting out halfway to the door.

Her mind cleared as her boobs finally stopped growing, resting on the floor a few inches past her knees. The flow of milk slowed, not stopping entirely, but slowed to a gentle leak. She slowly stood, amazed at how huge her tits had grown. Karen observed then as best as she could in the mirror. They were gigantic, reaching almost to her knees while she stood. Looking down, her oversized nipples must have been almost two feet away from her. Karen’s tits obscured most of her body, from her chest to her thighs. Even most of her arms were hidden behind tit flesh. And on top of all that, Karen could still feel gallons of milk inside them, despite all that she had expressed. She heard a noise and turned towards the door opening.

It was Stacy. “I was wondering why you were away from your desk so long…” she trailed off as she took in just how large Karen’s tits were. Suddenly, Karen was overwhelmed by the desire to have someone nurse from her. In a tone that allowed for no argument, she said one word.

"Drink.”
