“You’re a busty bimbo cow.” The tape recited the words in a flat, monotone voice, but Leanne didn’t mind.
“I’m, like, a busty bimbo cow!” She wobbled her tits back and forth obediently, like the cow she knew she was.
“You love your growing udders.”
“I loooove my growing udders!” She could just feel her stress and worry melting away. Therapy was the right choice!
“The bigger you get, the better you feel.”
“The bigger- mmm! I get, the better I feel!” Her hand had slipped, brushing one of her nipples.
A few weeks ago, Leanne had been stressed by her high-performance job. Her boss had recommended therapy. He knew a very good doctor, apparently. And now she wasn’t stressed at all!
Her performance at work had slipped, just a tiny bit. It was so hard for her to read some of the words on her papers. But Leanne was sure her boss would understand.
She could never understand why none of her underwear fit after a session either! The doctor asked her to take it off, to enhance her relaxation during therapy. At first she’d been anxious, but after a few sessions now she takes it off without being asked. He always laughs good-naturedly as she tries to stuff her tits back into her bra, letting out little whimpers the whole time.
The tape clicked off, and the doctor leaned back in his chair, apparently satisfied.
“Leanne, have you been a good girl?”
Those words did something to her. Leanne shivered in her seat, rubbing her thighs together, rubbing the nubs of her nipples between her fingers as pleasure coursed through her body.
“Mmmnnngh! Yes, Doctor.” She’s thinking how it’s a little strange she can never remember exactly what’s said on the tapes- only how good listening made her feel.
“Have you been doing your massages?”
“Uh huh!” She nods up and down, giggling a little. “Well, I started over lunch break, and, uh, lost track of time. But I did all of them!”
Her figure certainly showed it. No more subtlety of curves, Leanne was The Girl With The Big Tits and nothing else.
“Has anyone at work noticed your…transformation?”
“Oh, I think so! One person called me a dumb bimbo after I turned in a report. It might’ve had, like, mistakes?” She leaned forward, huge breasts slapping her torso, grinding against the seat.
“It’s ok, Leanne. You don’t need to worry about it.”
“I don’t need to worry about it…” She trailed off, staring blankly as the repetition triggered something deep inside.
“Was there anything else you wanted to talk about?”
She put a finger to her chin, collecting her thoughts, as her other hand gave a reassuring squeeze to one bloated boob.
“Oh! Uhhhh…I had some weird dreams lately!”
“Weird how?”
“It’s my titties…my udders.” Leanne shivered as she corrected herself, trained to find pleasure in that word.
“Always a different dream…but it ends in them being…” she frowns, concentrating. “…suckled!”
“And how does it make you feel?”
This time she blushes, placing her hand on her thigh, unconsciously.
“Uhhhhh….good? Kind of fuzzy? Just like I feel after therapy!”
“That’s very good news. I think you’re almost ready for the next level of treatment.”
“There’s more?!” Leanne is happy and giggly, pleased that she’s doing so well. And to think she was so skinny and unhappy before!
“Yes. Take this phone number, and call it, if you happen to lose your job soon. And I think we have time for one more tape. Are you ready?”
“Yeah!” Back to openly playing with her nipples, ready for the release her body was craving. Not even caring if it knocked a few thoughts out of her empty head.
The tape clicks on. “The more you touch them, the bigger they get…”
“The more I touch them, the bigger I get…”

“Pssssst. Hey, can you help me?” It was a high, urgent whisper, unlike the collected woman she normally was.
“Oh my god Sara! What happened to your chest-“
Sara cut off her co-worker, trying to keep attention away from herself…and her breasts.
“I can’t cover them.” She whispers. “Every time I try they start to…grow.”
She bit her lip, looking down as at her new figure. They were the perfect size, plump and firm, filling her shirt perfectly. Maybe overfilling it a little, she realized, as she felt a tug on the fabric around the sides of her bust. Slowly, by fractions of a cup size, her breasts were still expanding.
Her co-worker is staring, open mouthed, still thinking she might be pulling an elaborate prank.
“Do you know how crazy that sounds?”
Sara had begun to realize she loved it when people stared. Her nipples slowly hardened, pushing against the thin top. The idea of just awing someone with her figure…completely holding their attention…
There was a pregnant pause.
“My bra,” she started, talking slowly, delicately, “literally burst off me this morning.”
She was serious. No one talks about a prank like that.
“It was like…every time I breathed in, my chest pushed out, and then didn’t go back down when I let it out. I felt the straps…tighten…across my back…”
She was breathing faster, hands tightly at her sides, as she realized just describing it was turning her on. The memory replayed in her head, the twinge of pain from the tight straps, even her frightened moan as the clasps finally popped…
“Sara, are you ok?” She’d been staring into space.
“I’m fine!” She snapped, a little too quickly. “Just…what am I going to do?! I tried taping my nipples, as the next best thing…but they started to grow again.” She didn’t add that peeling the tape off in a panic had brought her almost to orgasm.
Only being completely topless would stop her from swelling. Even a thin, semi-transparent shirt would keep adding curves, just slower.
“That’s not even all of it.” She was speaking quietly again, as her shirt creaked audibly. She was noticeably bustier than she was a few minutes ago.
“They’re not just big…It’s like they’re…tight…or filling with something…” Why does it have to feel so goooood?! She was flushed, like a fever, even in a temperate room. And the way she extended the ‘o’ sound worried her…
“Just…do something! I can’t let anyone see me like this!” She grabbed her co-worker’s shoulders, pulling back as she realized her nipples almost brushed him, even at arm’s length.
Sara’s cleavage was deepening as her shirt shrank, each breath feeling the tightness of the constricting fabric. In desperation, she touched the hem, torn between going topless in the office and dealing with the continuing transformation she was experiencing.
The scary part was that both options turned her on.
Whatever she chose, Sara was rapidly running out of time to decide.

NEVER SLEEP WITH YOUR PUMPS ON.
It’s the first thing they teach the new cows, but you were just too busy to listen, weren’t you?
You looked so cute, blissfully murmuring to yourself as the pumps chugged, transferring drops of your cream to an overflowing collection jar. Filled with happy cow dreams.
This was only the start of the problem. Wasting your precious dairy.
Now, don’t cry. I know you didn’t mean to.
But there’s the second problem. As you slept, your nipples were sucked into the cups over and over. And there’s only one way they can react to that.
Longer, thicker, heavier- you started with room in the cups. But every cycle made the nubs lengthen just slightly. That’s probably what woke you up, the tips of those fat nipples rubbing the inside of the pumps.
You can barely touch them, right? Even the slightest brush makes you want to moan, to lose yourself in pleasure. Hand milking is almost impossible.
It’s a vicious cycle. The more you use the pump, the more you have to use the pump.
No, I’m afraid we just cannot afford the expense of a bigger set of cups.
You’ll stay in blissful suspense- tits spilling into your lap, whimpering as you try in vain to touch them, completely backed up with cream.
Every time you breathe in, your pulse will quicken, nipples tingling in anticipation of the release. Everything freezes for just a moment. But then, it fades just as quickly, leaving just a feeling of tightness and engorgement.
You’ll do anything to relieve the pressure? Well, I have one thing that can help.
It’s so simple even you can do it. Just take your breast in both hands- yes, just like that- tilt it up, and put the nipple in your mouth.
You’d better get started. There’s a very high production rate to keep up with.

(A discarded, torn page of a magazine, printed on glossy paper.) Uh oh! Big trouble for a (formerly) small woman!
This is the last message sent by Kaitie, a former fitness model, before paramedics found her, nearly immobile and completely helpless, sources report.
“I’ve never seen anything like it”, said one paramedic, who asked to remain anonymous. “She was surrounded by empty ice-cream containers, trying to reach…well, let's just say the only thing that still fit were her socks! She was practically laying on her swollen tits and belly!"
But Katie’s gain has been going on for some time. In an interview with one of her university friends, she revealed her shocking secrets!
“Katie used to be a fitness model…really proud of her abs. But one day she started to have incredibly strong cravings. The more she tried to diet the worse it got, she said. Soon we could all see it…her curves were getting softer by the day!”
“It didn’t help that she was spending so much on food she couldn’t afford new clothes! For a week all anyone could hear was the straining seams on her pants whenever she sat down!”
“One day things came to a head when she came to lunch with three trays of food! Someone asked her if she had a food baby and she just looked nervous. Then, while she was eating, POW! Her pants blew open, revealing a massive jiggly gut!”
“Everyone started to tease her and call her things like a gluttonous fat pig. I think she even moaned a little when trying to pull her pants closed. Then she ran- or more accurately, waddled- out of there, and we haven’t seen her since.”
“It was a good thing the way out was a double door!” She joked.
But Katie’s troubles didn’t end there. According to her Snapchat story, she got to a friend’s apartment just as her shirt buttons completely failed- leaving her completely unable to cover herself!
One neighbor saw her enter the apartment. “She was bouncing and wobbling like crazy! Everyone could see her belly just bulging out of her torn waistband. Then, she made the mistake of begging her tits to stop growing - and they did not like being told what to do! She must've lost three buttons at once - just a hair's breadth away from being exposed!"
Katie had no choice but to hide in the apartment- in the same kitchen her friend had purchased ice cream for a party!
Her last Snapchat posts show her whimpering and trying to hold back her expanding gut- a spoon still held tightly in one hand! She was getting too big to fit all of herself in the frame!
Sadly, Kaitie herself cannot be reached for an interview. Our inside sources say she’s referred to by doctors as ‘The Cream Balloon’ and still can’t get enough of hospital desserts-even after ruining her figure!

“I can’t stop it.”
Saying it out loud helped steady her, though there was still panic in her voice. Emma gripped the sides of her chair tightly.
For a moment the only sound was the drip-drip-drip of milk against the towel in her lap, and the faint sounds of the party outside. Then she let out a little whimper, involuntarily. There was a tight sensation in her nipples, like someone was flicking them every few seconds.
Emma was lactating! Thin streams of rich milk squirted from her nipples, landing on the towel in her lap, and earlier, the front of her shirt. Not that it would fit, now. She had pulled it down earlier to examine herself and was stuck like that, breasts exposed.
Sure, I could cover them with the towel…but it won’t stay dry for long…
She poked one breast experimentally, surprised by how firm it felt. How could she fill up so fast?!
Emma had been at a party when her formerly loose shirt began to seemingly shrink. She had put her drink down- something about a white russian, she wasn’t really listening- and stepped into a side room to check on her girls.
Ten minutes later, her towel was almost soaked- and drips became trickles became a steady stream. She was desperately, achingly full of milk.
“This can’t be happening.” Oh, it would be great if this were some perverted nightmare. But how would she even get to her car? The idea of walking out in front of all the guests…their eyes wide open at her new size…being praised for her milk production…even the taste-
She put her hands to her face, blushing. Why was the idea so hotttttt?
Emma was starting to really panic now, and she leaned back, gasping as she saw her breasts swell larger, taking up a little more of her view of the towel.
Ok, stay calm. I can’t really cover them…maybe with another towel…or I could climb out the window…
Even standing up, she found herself a little unsteady on her feet. Her center of gravity has changed, but her breasts didn’t jiggle as much as expected. Probably because they were so firm and swollen with milk.
Emma gave into temptation, gripping one breast around her swollen areolae and giving it an experimental squeeze.
“Mmmmmmm!” She threw her head back and moaned shamelessly, rewarded with a surge of pleasure and a huge squirt of dairy that spattered on the floor. More and more lewd images filled her mind- bent on all fours, spewing lust as her udders jiggled and wobbled below her- and her fingers began to rub her areolae, ready to repeat the experience.
“Mm-No!” Emma slapped her own hand away, standing as straight as she could with her expanded rack. “I’M NOT A COW!” Trying to fit as much defiance as possible into that sentence, but it came out louder than she expected. She covered her mouth again.
There was motion on the other side of the door, and someone tapped on the door sharply.
“Emma, are you alright? You’ve been in there for half an hour!”
“J-just a second!” She hurried to grab the towel, if only to cover her nipples- but what was she going to do now? Time was up! Nothing could hide or conceal her size from everyone.
Her inner cow stirred, and she knew the answer.

If you touch the cowbell, your body will start to change. Breasts will blossom into full, heavy udders that dangle and sway below you. Your thighs will thicken, complementing a plush rear decorated by a long, swishing tail.
You might think it’s just a late growth spurt at first. That belief won’t survive the first burst bra- you need to realize this is more than a few cup sizes. It’s a complete body reshaping.
If you hear it ring, your breasts will feel tight and full at first. Your nipples will darken and tingle, turning that delicate rose that means fresh cream.
I think you’ll try to pinch them, gently, because they’re so sensitive. But you’ll see a fat white drop of liquid on the tip- the first drop of many.
That’s right, you’re not just a cow, but a milking cow.
And if you were dumb or impulsive enough to lock the cowbell around your neck?
I’m sorry, but this is just your life now.
Every time those magnificent udders are milked, you’ll writhe against the restraints, and you’ll start to fill again, even as you’re emptied.
Being milked will be your singular focus in life. Your obsession. Every other goal you had pushed aside, just for another session of blissful release and hot cream.
Doesn’t that sound fun?
Now, be a good girl…a good cow…and open the box.
I think you already know what’s inside.

Rachel couldn’t take it anymore. She needed to do something to relieve the tension or she’d go crazy!
Touching her chest was like slipping into a warm bath. She’d never had sensitive nipples before this, but now it was electric. Just grazing them through the bra made her exhale slowly, flicking her tongue against her teeth.
“Rachel, you have to stop touching them! It’ll just get worse!”
Her co-worker spoke up. What was his name, again? He was taking me somewhere. The hospital?
The co-worker was talking, using a whole lot of big words like ‘feedback loop’ and ‘hormone levels’ but Rachel’s mind wandered.
This bra is cute…but wouldn’t it look better in a different color? A nice, light pink?
She heard the word ‘bimbo’, and looked up, briefly leaving her pleasurable haze.
"You mean I'm turning into one of those women on the news?!"
Bimbo flu. That was the name the news used, ‘tittybrains’ for the less polite. And she might have it.
She’d felt sorry for the women when she first saw the videos. Moaning and even mooing, having to be milked hourly, some women getting so massive they had to be rescued by cutting holes in their walls… but now, the thought was intriguing. She pushed her breasts up, wobbling them up and down on her chest, wondering what it would be like to be bigger. Fuller. Even more sensitive…
"Ohhh fuck! I'm getting huge!" Her thoughts were interrupted again, this type by a deep pulse of pressure, at the base of each breast. It was like a warm tingling, but spread quickly, moving towards her nipples. She moaned shamelessly as she felt them grow in her hands.
Rachel panted from the sensations, chest heaving against her bra as strands of previously neat hair fell over her face.
“I know you said not to rub them, but…mmmnngh….My boobies feel so goooood!” The last traces of intelligent, driven Rachel were disappearing, crushed under a mountain of warm titflesh.
One hand crept between her legs, trembling…

Even after being recovered from hucow traffickers, Leanne was having a hard time readjusting to civilian life.
Just one snap of someone’s fingers prompted her to lie on her back, waiting for the lotion or oil to be dripped onto her chest, gazing up with a blank, blissful expression.
Her captors kept her on a strict three-orgasms-a-day routine, and it’s hard to come off that level of sensation. She has to be reminded not to fondle herself, fingers always moving idly to her nipples.
In fact, because she keeps sneaking breast massages in, her growth is continuing, just slowly. If she gets big enough to suck her own nipples, the doctors are concerned she may start lactating.
Even after being rescued some hucows never truly escape…

“Ngggh…c’mon, Merilyn, don’t give up now!”
Panting heavily, she jogged on a treadmill, trying to compensate for the wobbling of her enormous udders.
A bead of sweat ran down into her bulging cleavage, shoulder bands pulling taut on her shoulders as she stopped and leaned over to catch her breath.
“Eighteen minutes?!”
Her mile time had been getting worse for days now. But she couldn’t give up! She could beat this!
She paused to adjust her straining sports bra, pulling the fabric down so the band fit against her underbust. Cleavage bulged over the top edge, and she hissed as a finger passed over a firm nipple. They were soft and warm and sensitive…
“Focus! I used to train for marathons…”
Another mile could do it. Just more exercise to slim down again.
Unfortunately for poor Merilyn, the curse she’s under is designed to work with her stubborn personality.
Every time her udders away and bounce, they get heavier. As she strains to burn off the extra weight, she’ll only add cup after cup of heavy delight.
As Merilyn began to jog again, there was a loud SNAP as her abused bra hooks gave way, and she almost lost her balance as her breasts wobbled, nipples tracing crazy patterns through the air.
The newly-developing bimbo couldn’t help herself - she moaned, nipples slipping between her fingers, begging for attention.
How big would she get before she realized what was happening?
Would she even want to stop?

“Please, this punishment is killing me! I can’t take anymore…please!”
You begged into the intercom, already feeling another wave of sickening pleasure build up in your breasts.
Or…they’re udders now, aren’t they? Calling them the wrong word what got you into trouble in the first place. Management is very strict about terminology.
Your breasts pulsed, the same rate as your racing heart, and it seemed like the fabric binding them pulled tighter. Veins stood out on the surface as thick nipples poked out like thumbtips, desperate for attention.
Usually, when they got like this, it only took a few tugs to get the milk flowing. But the glue holding your nipples closed held firm. They’ve never been this engorged before, even when you overslept and missed morning bell.
They couldn’t be covered, couldn’t be ignored, couldn’t be touched- any stimulation just made the milk glands work faster, making the pressure worse and worse.
You tried to close your hoodie, almost moaning when the zipper teeth lightly grazed a nipple. All you could think about was the pump, and the relief you knew it would bring.
When would they let you do it? Would they let you? The uncertainty hurt worse than the pressure.
All you could do was swell. Lowering your udders to your desk, speaking into the intercom again, shamelessly sighing as the cool laminate eased the tingling a little.
“Hnnngh…please, just a little…”

You looked up from the desk at the resort pharmacy, eyebrows raised as the view was blocked by a pair of massive breasts, each capped with a fat brown nipple.
“Ma’am, going topless isn’t allowed, you need to put on a bikini-“
“It snapped off! Nothing fits anymore…” she whined, staring down at her chest.
She’d stopped by a few days earlier. A bit shy, not the type to flaunt her figure. And certainly not half as busty.
“…This growth will stop soon, right?”
A mixture of fear, curiosity and arousal sparkles in her eyes.
“I’m sorry, ma’am. There was a problem with the second half of your treatment-“
“You mean I’m going to keep growing?!” She cut you off, talking in a high, breathy voice.
Most breast expansion pills came in two doses- one for the initial hormone spike, then another to stabilize it and stop the growth.
She jiggles her breasts from side to side, probably not even realizing she’s doing it.
“It could be weeks before I’m able to get the medication…”
“Ma’am, we can get it in a day or two if you just-“
“It’ll be so terrible to get even bigger…feeling my new bikini straps tighten against my back…”
Her hands cupped them, circling around the edges of the areolae. At that size they must be very sensitive. Frantic eyes searched for approval.
“I may never stop swelling…getting even bustier…”
Did she even notice the blonde streaks spreading across her hair?
She leaned forward, placing both hands on the counter, letting her chest sway back and forth enticingly. She bit her lip as she felt the weight and heft.
“Uh, do you have any more of the first type of pill? Just to make sure it’s working right?”

Bigger. Thicker. Heavier. Rounder.
None of those words meant much before, but Mal whispered them now as she raised her phone, hands shaking, to take a comparison photo.
Keeping track of her size was mostly denial at this point. There was still some sane explanation, retaining water, anything that didn’t involve her blowing up like this.
The photo didn’t lie. Her belly was slightly bigger, thighs more plush, than the last one. She’d been gaining about four pounds an hour, for a little over a day now. More if she got…excited.
Mal found her fingers moving up to a firm nipple and jerked her hand away, stifling a moan. Something about her clothes tightening around her curves…
She had to change clothes twice, now. First in shock and horror, as her belly popped the button on her custom-tailored work skirt, and later with quiet resignation as she found a mistakenly purchased XXL dress in the back of her closet. And even that was getting tight.
She sighed, cupping her swollen belly in both hands, the fabric straining slightly against her plush gut. Biting her lip, watching as her nipples tented the fabric, she rubbed her thighs together, trying to fight the sensations.
“I’m not that much of a picky eater…” She meant it as a defiant gesture, but it came out as a whimper, tinged with desperation. She lost her breath so easily now, but that was to be expected, carrying around a hundred extra pounds. And more soon, if this didn’t stop.
That was how it started wasn’t it? Being rude to that waitress. So she sent back a dish or two! Excuse her for caring about her waistline!
Oh my. That was it, wasn’t it? Some sort of karmic debt?
Mal’s train of thought was interrupted by realization she couldn’t see her feet anymore when she looked down.
No. She had to focus. What had the waitress whispered in her ear, right before she left? That sent a curious tingling feeling down her spine, ending right between her legs?
The exact wording was important. It might provide a clue to stopping…oh, please no…
“It was…Nghhh…big enough to roll…”
