Factory Girl

Written as a commission for an r/BreastExpansion user (who asked to remain anonymous). Initial brief at the bottom.

Natalie folded the newspaper shut, and stepped into the factory. “Free breast enhancement!” the headline had screamed. She couldn’t be more excited. Natalie had always been flat chested, unable to properly even fill an a-cup. No one had ever said anything to her, but in her mind, she was distraught. She’d always wanted huge tits. Not just big. Huge. And nature had denied her. She’d tried everything to fix this, and had almost given up hope, but then she’d seen the ad. And here she was.

She stepped in through the doors, to a kind of laundry. There was large vats drying clothes, and – Natalie stopped noticing, because everyone walking around was incredibly busty. Everywhere she looked, huge-titted women were working away, their large breasts jiggling. They all wore short legged white jumpsuits, with ample room in the chest, but for most of them, it wasn’t enough. Their huge tits stretched against the fabric, and pulled it away from their chest – ten inches or more. Natalie stared, aghast. She felt even flatter than usual.

She heard a ripping round, and whirled round to see a tall brunette, chatting to huge friend of hers giggle embarrassedly as her jumpsuit began to tear down the middle, ripping as – “oh my god”, thought Natalie – her breasts were growing! Natalie felt her heart pound, as the jumpsuit stretched and tore as this lady’s tits grew and grew, tearing out of her clothes. She didn’t understand what was going on, but found herself growing incredibly aroused.

Out of nowhere, a man appeared, and Natalie in her aroused state, couldn’t help but notice the large bulge in his trousers. Really large. He tapped the brunette on the arm, and she turned, pressing her growing tits into his chest. He stepped back, but Natalie could see his erection grow hugely in his trousers. The brunette giggled, bursting further out of her jumpsuit. Natalie gasped. Her tits were enormous! And so huge and firm. The man took her arm, and they left. Natalie could have sworn the brunette’s tits were still growing.

Natalie found herself growing uncontrollably aroused, but before she could find a bathroom, she felt a hand on her arm, and a handsome, tall, smiling man stood before her. He crooked a finger, and beckoned Natalie to follow him. She did so, feeling uncontrollably excited, and really aroused.

In a small office, the man sat down and spoke:

“So, you want huge tits?”

Natalie nodded, unable to speak. Her mouth was dry. Finally.

“How big?”

The man spread his hands out in front of his chest, cupping imaginary breasts. “This big?” His hands were about ten inches away from his chest.

Natalie shook her head.

He raised an eyebrow. He moved his hands another five inches away.

Natalie shook again. Her eyes were glowing.

He moved another five.

Natalie felt herself growing incredibly wet.

She shook her head again.

The man raised both eyebrows, this time.

“Ok”, was all he said.

He opened the drawer, and produced a bottle of pills and a contract.

“Before we start, there are some…conditions”, he said, smiling. Natalie had the pen in hand, ready to sign. He beckoned her to a bookshelf in the corner of his office. Pulling a tome, it flipped to the side, revealing an elevator.

“We used to have a staircase, but it proved…impractical.” said the man.

The elevator was surprisingly roomy – not tall, but very long – and moved at a pace.

They stepped out into a long, metal gantry, and Natalie gasped in amazement.

Down below, strapped to various contraptions, was a row of women with the largest breasts and asses she had ever seen. Most of their chests stuck out fifteen inches in front of them, but a lot were larger. They were lying on their stomachs, their huge, wobbling butts up in the air, their tremendous udders hanging down, with large plastic suction cups covered their huge, distended nipples. Thick, white fluid was shooting down tubes, running from these colossal breasts to large vats on either side.

“Once we created these pills, we found there were…side effects”, explained the man. So, for free pills, we’ll also drain you, so you don’t grow too big, and in return, we keep the milk.”

Natalie had seen enough.

“Give me the contract”. She grabbed a pen from the man, and signed it on the spot.

“But I want to be bigger than them.”

The man raised his eyebrow again.

“There’s something I didn’t get a chance to tell you.”

Down below, one of the girls was writhing in her contraption.

“Fuck me! Right now!”, she cried.

“The whole process is rather…arousing.” said the man. “Unless the girls are serviced, they become incredibly pent up. So we made an alteration to the drug.”

A man stepped out of a door below, and even from up on the gantry, Natalie could see the very big bulge in his trousers. It grew bigger as he approached the girl. She licked her lips.

He removed his trousers, revealing a truly huge cock. The moaning girl saw it, and squirmed even further. “Quick, fuck me right now! Right now!” she cried.

Natalie watched with growing arousal as the workman walked up around the girl, and slowly hefted his massive dick inside her. She practically screamed with arousal, and milk went shooting faster and more thickly down the tubes, as she was brought quickly to climax.

“So on men it makes them…bigger, too?” Natalie asked, feeling a little faint.

“Exactly. Do you want me to tear this up?”, asked the man, gesturing to the contract.

Natalie shook her head, faintly. “Don’t you fucking dare”, she breathed.

***

Later in the day, Natalie was set up in a modest room, on her bed. She’d taken her bra off, knowing she soon wouldn’t need it. Opening the wardrobe in her room, she saw a large collection of massive bras, with no cup size written on them. She practically drooled at the thought of not only fitting in them, but being too big for them. “Too big!”, she thought. The two words turned her on so much.

There was a knock at the door, and the man walked in. Natalie briefly noted his huge crotch. It looked even bigger than the workman’s she’d seen. God she was horny.

He handed over the bottle of pills.

“These are the experimental ones you mentioned?”, Natalie asked.

The man nodded, looking serious.

“You need to be careful with these”, he warned. “They really are strong. We want you to be able to leave here when you’re done growing.”

“What if I’m never done?”, Natalie asked, with a glint in her eye.

The man smiled. Natalie knew he was underestimating her.

“Take a pill for each growth session. Wait for one session to finish before you take the next. When it gets too much, press that button and we’ll get you milked…and serviced.” Natalie’s heart pounded at the thought. “When you’re done, you can leave. Just send us the excess milk. You could even get a job upstairs like many of the other girls.”

Natalie had stopped listening. It was time to grow enormously huge tits and ass. She’d been waiting for this since the cruel end of puberty.

“I’ll be seeing you very soon”, she said to the man, who smiled and left.

Natalie sat down on her bed. She’d brought special clothes for the occasion. She decided to start with an orange polo neck jumper. It was XXXL, and hung off her. She was wearing very loose jeans and way-too-big underwear. Not for long. She popped the first pill, and sat back.

It only took a few seconds. Her heart was already pounding, but she felt a tightness in her chest almost instantly, as her breasts began to grow. This was it, the moment she’d been waiting for. She was indescribably excited.

She felt her breasts begin to fill up, pumping bigger and bigger with milk. The jumper was thin, and she could see her breasts slowly bulge forward, in perfect, round orbs. She could already see her nipples poking out.

Slowly, they grew and grew. She estimated they emerged about three inches now, and were already really round and firm. She hefted them in her hands, and a shot of arousal rushed through her. They were incredibly sensitive. She didn’t dare start playing with them – she’d come on the spot. Her breasts swelled bigger, bulging outwards against her tightening jumper. She could feel it riding up around her waist, as her tits pressed outwards. The fabric moving against her hard nipples was intensely pleasurable.

She lay back against the wall on her bed, watching her tits expand. They grew bigger and bigger, inching outwards from her chest with every passing second. She couldn’t believe how large they were already – bigger than she’d ever imagined, and she was barely getting started. They bulged out about five inches in front of her, pulling the jumper tighter and tighter as they swelled. At this point, she felt her ass beginning to expand.

Her jeans were incredibly loose, but she could feel her ass slowly bulging out, filling up the space in her jeans, pushing against the fabric, growing bigger and bigger with each passing moment, mirroring her huge tits, that were also swelling and bulging outwards. She was stretching both ways, getting higher and higher up on the bed as her ass grew bigger and more curvy, and bulging outwards from her chest as her already huge tits expanded and swelled larger and larger and larger.

She was now a very busty and big assed girl. Natalie stood up, and fell over straight away, her huge tits cushioning her fall. She was so heavy. A massive jolt of arousal shot through her as her tits rubbed on the floor, and she was amazed at how far they spread out when she fell on them. They were huge, round and firm, and jutted out about eight inches in front of her, like two large melons. She loved them, but there’s no way they were big enough. She felt her large ass in her jeans, but it was still a little loose. It was time to supercharge this. She popped two more pills.

The effect was instantaneous. Natalie’s ass was first hit this time. She was looking at herself in the floor-length mirror, admiring how her jeans were tightening around her curvy ass, and how large her breasts looked, when she doubled over. She was becoming incredibly aroused, to the point where she could barely think straight. To make matters worse, when she bent over, her huge tits pressed into her legs, rubbing against her nipples, which sent fireballs of arousal around her body. She was becoming uncontrollably turned on.

She staggered to the bed, her thighs rubbing together as her ass thickened and grew larger, bulging tightly into the jeans which were fast becoming too small. The growth was quicker and more insistent this time, as Natalie’s ass swelled and bulged against the tight denim. She began to feel rips, as her huge, swollen ass was pushed as far as possible against the material. Lucky she had bought cheap jeans. The tears began to show, and she could see patches of skin bulge through the gaps as she swelled and bulged bigger and bigger and bigger.

She was incredibly aroused, and she suddenly noticed her breasts were doing the same thing. They were now around ten inches, straight out in front of her, in huge, round zeppelins, which protruded further and further with each passing second. Her XXXL jumper was now very tight around her chest, and she noted with increased arousal that her breasts had swelled to the side of her, and were sticking out a couple of inches either side of her body. Her boobs were wider than she was! This thought turned her on even more than she thought possible.

Natalie lay back on her bed, but was amazed at how high she was, her tremendous, still growing ass cheeks supporting her like two huge cushions underneath her swelling body. She looked down to see her tits expanding like two inflating beach balls on her chest, just growing and growing. She was starting to get so aroused, she didn’t know what to do. Suddenly, she remembered the button.

She didn’t want to get milked yet – that would mean stopping her breast growth, even temporarily – but she did want to get fucked. Repeatedly. Instead, she held off. She wanted to be the biggest girl in this place, by miles. Hands shaking, she took the pill bottle, and grabbed another pill. She went to put it in her mouth, but her breasts and ass, almost as if they’re were anticipating it, bulged forwards, and she dropped it down the neck of her jumper, which was stretched forwards three inches by her titanic bust, which now bulged out twelve inches. She felt the pill fall between her humongous breasts, which were firmly and hugely pressed together in the jumper; there was just no room for their expanding bulk.

She could feel the pill disappear between her huge tits, so she reached for another. She was so horny, she could barely think straight, but one thought remained. “Get bigger”. It resonated through her mind, and allowed her to take one more pill, as her breasts swelled bigger, and her growing ass began to burst out of her jeans. She was too horny now. Her mind was just full of dicks and swelling breasts and massive asses, as she tore through the remains of her jeans, and her now incredibly tight orange jumper heaved and groaned, trying to contain the massive load within.

Natalie was close to passing out. Her breasts were so huge and full, and they were just getting bigger and fuller with every passing moment. She didn’t want to do anything to stop the growth, but she genuinely thought she was going to explode. As her tits expanded beyond the fifteen inch mark, she grabbed the pill jar, and threw it at the button the wall, her huge tits wobbling and bulging all the time, her ass growing bigger.

Her aim was true, and in seconds, a man in overalls came in. Natalie lay back in her bed, a pumped up supermodel with a now-sixteen inch protruding bust bursting out of her ripping jumper, her enormously large underwear almost swallowed up by her tremendous ass.

The man looked shocked, and went to pull Natalie up. “We’ve got a code white! Milking a priority!” he yelled into the walkie talkie.

“What have you taken?”, he asked Natalie, as he dragged her huge titted and massively-assed body upright. “Can you walk?”

“I need your cock, now”, murmured Natalie, blinded with lust. She reached a hand down to grab his dick, but it just bounced off her growing tits, which were spread out like two huge balloons below her, impossibly wide. She was dimly aware of the ripping of her jumper, which just couldn’t contain her colossal melons much longer. The seams were going, the fabric ripping, the two enormous breasts within struggling to break loose.

Natalie felt herself carried down a corridor, squeezed through a couple of doors (she felt her breasts pressed together to fit through, which was incredibly, distressingly arousing – both that her tits were being touched and that they were so big) until she reached the main chamber.

She walked along on shaking legs, as her still growing tits bulged bigger and bigger, ripping out of the jumper. Two men were supporting her on either side – her tits were just so heavy. It was stunning. “Get me on a machine, and get me fucked right now”, Natalie growled, her huge tits wobbling and bulging with every movement.

After what seemed like hours to Natalie’s lust-addled mind, she was lowered onto the machine. The men went to remove her jumper, but another growth spurt hit, and her humongous tits tore out of their orange prison, as her ass expanded further, swallowing her underwear completely. It looked like a piece of thread between two beach balls.

“Milk me, noooooow”, moaned Natalie. Her tits were so full, she thought they would burst. They were so huge she had to be raised up, so they didn’t spread out against the floor. The suction cups were attached – the largest size, which barely covered the vast amount of tit – and turned on.

Natalie almost blacked out. It was like twenty orgasms in one, as her breasts surged forth what seemed like litres of milk, sucked from her incredibly engorged udders. Amazingly though, despite the huge arousal, she was only getting hornier.

“Fuck me! Fuck me this instant!”, she half demanded, half begged.

She saw the man, the boss, just before she felt a pair of trousers drop to the floor.

“You took too much. I warned you not to. You’ve been a very bad girl”

“Oh god, we both know I’m going to be the biggest girl in this place”

“I think you already are. That’s why you’re getting the personal treatment.”

“My god fuck me right now”! shouted Natalie.

“I’m rather big too, you know”, said the man.

“Whatev-ooooooooooh!” cried Natalie, as she felt the man’s gargantuan cock press into her cunt. He was colossal. He could barely fit inside her, even as ludicrously wet as she was.

After a bit of gentle easing, he managed to fit his enhanced member inside, and began to slide back and forth, rubbing every inch of Natalie’s wet cut with his humongous cock. Natalie was enraptured. She was turned on beyond rational thought. She could think of nothing other than her bulging, still growing breasts shooting out milk, as her ass expanded into the man.

She was still growing, bulging and expanding ever bigger as she was fucked by the biggest cock she’d ever seen. The sensations were beyond description, as her tits were milked, her cunt was fucked, and she bulged, grew and expanded all the while.

“Oh my god”, said the man. “I’ve never felt anything like this”.

“Get me some pills!”, screamed Natalie.

“Get her some pills!” repeated the man.

Instantly, a bottle of pills was produced, and three were put in Natalie’s mouth.

She swallowed them in a split second, and felt the growth increase, as the milk flowed faster and faster from her swollen udders. Her breasts grew faster and faster, visibly swelling into the floor, pushing her upwards, making the suction cups look like little toys around her twenty inch boobs. They swelled bigger and bigger, larger and larger, as her bulging ass cheeks pressed into the flat stomach of the man, pushing him away from her. Luckily, she could feel his dick expanding inside her, so she knew he’d taken a pill too.

Part of her ass expanding had obviously made her cunt bigger, as she found she could just about take his huge, growing cock, as she tightened her cunt around his dick with every successive orgasm. With the final, huge burst of arousal around her body, she felt his cock harden ever further, and a huge, primal burst of cum shot out, filling her cunt. Her tits responded in kind, sending huge bursts of milk up the tubes, and then, as if the world had ended, everything went quiet.

Natalie breathed deeply, then fell asleep, exhausted, the man slumped over her.

She was really glad she’d come.

Original idea:

“Okay so the story would take place in a milking factory where the “cows” are women. The company that owns the factory hires women and then gives them a pill that basically grows their breasts and ass with no weight gain. These women are then hooked up to milking machines that basically milk them, causing huge amounts of pleasure.

The guards working in the factory are all men that changed the formula to grow their dicks and balls instead of their breasts/butt. The men there would fuck the women who are already really horny from the milking. The main character could be a flat-chested woman who always wanted big tits so she decided to apply to be a cow at the factory. She would eventually grow to have bigger breasts and a bigger butt than the other women at the factory. During the story she would be taken advantage of by men and even women.”
