Just Add Milk (BE, M2F, Lac)

[[ Note: I've been working on this story for a couple of months and just finished it.

Jamie Smithe looked over the shoulder of her girlfriend and at her computer monitor.  “You can’t be serious.”

Elena smiled.  “Look, I know it’s a bit extreme, hon, but if what they’re promising is true, can you afford to pass it up?”

Jamie smirked.  She knew that Elena was trying to help.  She’d been so supportive when Jamie had started to transition.  Still, this was insane.  “Volunteers wanted for experimental lactation study.  One thousand dollars for the first month.  Bonuses are available based on results.  All genders are accepted.”

Elena drew Jamie’s fingers to her lips, kissing them as she often did.  “Do you remember Rachel?” Elena asked, smiling.  Jamie did, vaguely recalling the library studies major.  “She’s the one that sent this to me.”  Jamie was shocked when Elena pulled up two pictures.  One was the Rachel she remembered.  The other has boobs almost as big as her head.  “This was after a month.  She admits that the doctors said that the amount of growth is atypical, but still.  I know how much you want larger breasts, hon.  Isn’t it worth the risk?”

Jamie pondered that.  She narrowed her eyes and looked at Elena.  “And this has nothing at all to do with the fact that you have a lactation kink?”

Elena grinned.  “Maybe just a little bit.”  Tilting her head, she kissed Jamie’s cheek.  “I’ll do it if you will.”

Jamie sighed.  “Fine.”  She bit her lip and grimaced as her groin became uncomfortable.  She was tucking and the thought of the pair of them having milky tits was making her horny.  She could feel her nipples stiffening as well.  “We’ll go in the morning.”

Jamie made her way to their bedroom.  Taking off her crop top, she reached back to unhook her bra.  She frowned as she looked down at her chest.  While her breasts had grown somewhat since she’d started on estrogen six months ago, she barely filled her A-cup bra.  She wiggled out of her skirt and panties, allowing her stiffened cock to hang freely.

While Jamie wished the damned thing was gone, Elena was bound and determined to enjoy it while Jamie still had one.  White Jamie was on testosterone blockers, it hadn’t decreased Jamie’s ability to get an erection, much to her annoyance.  Still, if things went well over the next eight months, it would be gone anyway.

Stepping into the shower, Jamie began to soap her body.  Her body was hairless from the neck down.  Her muscle tone wasn’t as defined as it had been before she had started taking estrogen.  She had two, small, pert breasts and her hips and ass had gained a slight bit of curve.  Overall, she had an androgynous appearance, except for her long brown hair which she kept in a feminine style.  She just wished her boobs were bigger.  A lot bigger.

Thinking about having larger boobs, as usual, made her cock even more stiff.  She took the eight-inch shaft in her hand and began to stroke it, thinking about her boobs growing.  How big would they get?  As she pictured her breasts swelling, milk dripping from her puffy nipples, her cock throbbed, spurting cum in the shower.  Bracing herself against the shower wall, she waited for her cock to finish.  Part of her would miss this feeling.  A very small part.

Once she wasn’t weak in the knees, she soaped her dick clean, washed and shampooed her hair, then turned the shower off.  Getting out of the shower, she dried off.  Elena was standing at the bathroom door, naked from tip to toe, her finger twirling her long blonde hair idly.  She was voluptuous and just shy of what most would call curvy.  Her D-cup breasts sagged a small amount but that did little to detract from her farm-girl good looks.  “Did you save me any hot water?” Elena smiled as Jamie dried her hair.

Jamie hid a grin as she moved to dry off her chest and back.  It was a common joke between them.  It was why Jamie showered first.  Elena loved to take long showers.  Finishing drying off, Jamie kissed Elena’s cheek.  “Plenty,” Jamie said before smacking Elena’s ass, causing her to jump.  Jamie laughed as Elena stuck her tongue out at her.  Making her way to the walk-in closet, Jamie grabbed a pink nylon nightgown and slid it down her body before sliding into bed.

Almost twenty minutes later, Elena went to bed wearing only panties.  She slid up against Jamie, her back to Jamie’s front, her head against Jamie’s left arm.  Given Jamie was eight inches taller than Elena, Elena usually ended up being the “small spoon”, which suited her just fine.  She ground her ass against Jamie’s crotch.  Jamie smirked.  Sliding her hand between Elena’s legs and down her panties, her fingers darted against Elena’s clit.  Jamie’s left hand tugged gently on Elena’s nipple.

“I bet you can’t wait to be milked,” Jamie said as Elena moaned.

“I can’t wait to be milked by you,” Elena corrected her.  “Or to milk you myself.”

Elena’s hips rocked and Jamie quickened the pace.  Elena cried out not much later.  As her body eased, she snuggled against Jamie.  Jamie kissed Elena’s shoulder before pulling the sheet over them both.

Tomorrow, they’d both become cows.

Jamie waited in the clinic room.  She’d filled out all the forms and, after a brief interview, she’s been accepted into the program.  She hoped Elena would be, too.  There was a knock at the door before a busty woman wearing pink scrubs walked in.  Her name tag read “Betsy”.  It was hard for Jamie to avoid staring at the nurse’s massive rack.  Her breasts were each easily larger than her head.

“Hi there, sweetie.  Welcome to the Nucow program.  I’m Betsy, your nurse.  I just need to verify your date of birth,” Betsy said, sitting down and opening a small case.  Once Jamie had done so, Betsy smiled.  “Okay, I’m going to need you to take your shirt and bra off.”  Jamie complied, a little self-conscious about how small her breasts were compared to Betsy’s.  Betsy prepared one needle and disinfected the bottom of Jamie’s right breast.  “This is going to feel cold, okay?  Nothing to worry about.”

Jamie bit her lip and watched as Betsy poked her right breast with the needle and injected the drug.  “Well, there’s no going back,” Jamie thought.  She watched as Betsy repeated the process with Jamie’s left breast.

“Now, I wouldn’t expect quick results.  If things go well, you’ll come back in for a booster in about four weeks.  With you being on testosterone blockers and estrogen, we’d like you to contact us if anything unusual occurs.”

Jamie smirked at that.  “I read that you were accepting non-trans persons.  How is that different from a man who wasn’t taking t-blockers?”

Betsy smiled.  “Oh, that’s a great question.  They receive a different drug cocktail than a trans person would.  I can’t go into much more detail as this is only the second set of clinical trials.  This is all highly proprietary.”  Jamie didn’t understand but it was more or less moot.  She put her clothes back on.   Betsy handed Jamie a small booklet labeled “Nucow Dos and Don’ts”.  Betsy grinned at Jamie.  “Don’t forget to stop at the front desk for your first check.”

Betsy stood and walked to the door.  Her rear was just as big as her tits.  Jamie thought of Elena.  She’d have been ogling the nurse for certain.  Jamie followed Betsy out to the waiting room.  Elena was already there smiling broadly.

“Did you get accepted, hon?” Elena asked excitedly.  Jamie nodded.  “Why don’t we go cash these and celebrate?” Elena said, waving the check in front of her.  Jamie smiled.  Her girlfriend’s attitude was infectious.

“Sounds like a plan.”

By the time they’d made it to their bank and deposited the checks, Jamie’s stomach was gurgling.  She was reading through the “Nucow Dos and Don’ts” while Elena drove.  There was a recommendation to eat a diet high in fat and calcium to assist with the production of milk and breast tissue.  Ultimately, Elena decided on a buffet.  Given how hungry Jamie was, it seemed perfect.

Both Elena and Jamie ate almost double what they normally would have before the pair was satiated.  Both went back for ice cream twice.  It filled a craving they both had.  “It’s too bad they didn’t have chocolate milk,” Elena had commented.

The pair made it back to their car, yawning.  “I am so ready for a food coma,” Jamie said as she slid into the car.  

Elena smiled.  “Sounds lovely.”

Ten minutes later, they’d pulled up to their apartment.  Ten minutes later, the pair were curled up, naked, and in bed.

Jamie dreamed of the pair of them in a barn stall with Elena sucking on Jamie’s nipple.  Jamie’s breasts were both larger than her head as were Elena’s.  Jamie’s cock was gone, which was common in her dreams.  Still, Elena’s lips around Jamie’s large nipple were the focus.  Jamie mooed in pleasure.  Her breasts felt heavy and full.  It was heaven.  It was…

Jamie woke to the alarm clock going off and the sensation of Elena’s lips around her nipple.  Jamie smiled down at Elena.  “Enjoying yourself?” Jamie teased.

“Just practicing,” Elena noted.  She mocked a pout.  “Somewhat surprisingly, your boy bits weren’t getting the message.”

Jamie looked down and Elena was correct.  Her dick was completely limp, though her nipples were rock hard.  As far as Jamie was concerned, this was perfectly fine.

“It’s okay.  I need to get up for work anyway,” Jamie said.  Elena pouted.  Jamie worked remotely from home.  Elena worked at an art studio downtown and gave lessons on glass blowing and stained glass to apprentice glaziers.  Elena impishly gave Jamie’s nipple a long lick, causing Jamie to moan in pleasure.  As much as Jamie wanted to indulge in Elena’s desires, she had to get ready,

Thirty minutes later, Jamie was sitting in front of her computer, sipping coffee, and wearing a t-shirt and slacks.  She had to finish this character model and start working on the animation.

It was a few days before Jamie noticed any changes.  Her bra felt uncomfortably snug as she was getting ready for the day.  By the time lunch rolled around, her shoulders were aching.  Taking a moment while waiting for her food to microwave, Jamie slipped into the bathroom and took her blouse off.  Looking at herself in the mirror, it was obvious that her breasts were spilling out of her bra.  Thinking about it, there wasn’t time to go shopping for a new bra.  She decided to risk going braless until the end of the shift.  When she buttoned her silk blouse, she frowned.  Her nipples were poking obscenely through her top and were larger than the button size they’d been since she’d started her transition.  They were closer to gumdrops now.

Luckily, there weren’t any online meetings that day.  Still, as soon as the day was over, Jamie grabbed her purse and headed for the door.

An hour later, she was home again.  She’d gone up to a large B-cup or small C-cup, depending on the bra.  In four days, her breasts had grown almost two cup sizes.  Was this what Betsy had meant by “anything unusual”?  Given the rapid increase, Jamie only purchased one bra.  Jamie wondered if Elena had grown as much.  Staring at herself in the mirror, she realized two things: she’d forgotten to tuck herself that morning, and that she couldn’t tell that by looking in the mirror.

Wiggling out of her panties, Jamie was surprised by how small her cock looked.  It might be three inches long.  Maybe.  It was also completely flaccid.  Her nipples, though, were rock hard.  Jamie cupped her breasts and mimicked milking herself, pinching her nipples.  She moaned in pleasure.  Her cock did begin the stiffen, but, to Jamie’s surprise, it didn’t increase in size.  Feeling naughty, Jamie stepped into the shower and continued to play with her breasts and nipples.  After a few minutes, Jamie managed to do something she’d only dreamed of.  Her cock began to jerk and spurt as Jamie came from strictly playing with her tits.

“You know, you might have enjoyed it more if you’d let me suck on your cock while you played with your boobs, Jamie.”

Jamie turned to see Elena, her breasts hanging freely while her hand was down her panties, rubbing herself.  Elena’s breasts were larger.  Jamie was certain of it,

“You could let me finish you off,” Jamie teased.

“I could,” Elena replied with a smile.  She wiggled out of her panties and turned toward the bedroom.

Moments later, Elena was lying down on their bed with Jamie between her legs, licking her out.  Elena’s hand groped and massaged her tits while Jamie licked her pussy.  As she neared her orgasm, Elena began to cry out.  “I’m a slutty cow, moo.”

Instead of finding Elena’s mooing silly, it turned Jamie on more.  She redoubled her efforts.  Moments later, Elena was holding Jamie’s head between her legs as her body shook, her orgasm overtaking her.

“I love being a slutty cow,” Elena said with a lusty smile, “and I love that you’re one, too.”

“Not yet, I’m not,” Jamie thought, “but soon, I hope.”

After a few more days, there was no denying it.  Jamie’s breasts had continued to grow as had Elena’s.  Jamie was also ravishingly hungry most of the time.  She swore that most of the calories were going to her breasts, though, staring at herself in the mirror, her butt did look like it was rounder, too.  Her jaw and ribs were a little sore and her stomach felt odd.  There was a general discomfort there.  Her dick was smaller than it had been, too.  It was barely an inch long now and never got hard even though she got horny at the smallest things.

As it was her day off, she showered quickly before slipping into a pair of panties, leggings, and a pink t-shirt.  Her bra from a few days ago didn’t fit at all.  She grabbed her phone and dialed the clinic.  Yes, that amount of breast growth that quickly was unusual.  Yes, they could see her today.  Jamie moved back into the bathroom and put her makeup on before grabbing her purse.  Elena was already at work.

Locking up behind her, Jamie headed to her car and drove off.

Betsy greeted her at the door, smiling cheerfully.  Jamie was certain Betsy’s boobs were bigger than last week, but couldn’t guess how much.  She didn’t have the courage to ask.  Jamie was led back into one of the patient rooms and was asked to take her shirt off.  Betsy pulled out a measuring tape from one pocket.

“When you first signed up, you were a 34A, Jamie.  Now, you’re up to a DD cup.  That’s astonishing!”  Betsy exclaimed.  “Are you in any discomfort?” Betsy asked as she prodded Jamie’s breast, which caused Jamie to wince.  

“Now that you asked.  My breasts do feel a bit tender.  I’ve had some stomach issues, but that could be from food.  Also, my breasts aren’t the only thing that’s changed size,” Jamie admitted.  When Betsy gave Jamie an inquisitive look, Jamie bit her lip.  “My dick.  It’s tiny now.  It used to be about six inches long.  Now it’s barely there.”

Betsy made some notes on the computer.  “Hmmm… that is odd indeed.  We’d like to run some blood work if you don’t mind?”

Jamie nodded.  “That’s fine.”

Betsy smiled.  “Are you free Monday?  If everything checks out from the tests, we might be able to give you the booster early.”

Jamie thought about it.  “If you can do it before noon, sure.”

“How’s nine A.M. sound?”

“Perfect.”

Betsy smiled.  After drawing blood samples, she thanked Jamie for coming in.  She was also given a gift card for a local lingerie boutique.  “It’s sort of on us that you’re outgrowing your bras.  It’s the least we can do.  Oh, and I’d recommend maternity bras.  You’re going to be lactating soon enough.  Might as well make it easier for you to pump your girls.”  Betsy gave a dreamy grin before coming back to reality.  “Which reminds me…”

Jamie watched as Betsy walked into the back room and emerged with two boxes. “These are for you and Elena.”  Taking them, Jamie realized they were breast pumps.  “Once you start, presuming you both do, these will help.  We ask that, for the first week, you refrigerate the milk overnight if you can’t drop the milk off the same day.  We want to check them to insure everything is in order.”

Jamie nodded.  The thought of milking her growing boobs aroused her and she was certain her nipples were poking through her shirt.

Jamie had no problems finding the boutique.  She even found cow print nursing bras.  Once she had the bra on, her back felt better immediately.  Tugging her shirt back on, she paid for the bras and left.  She stopped to get food on the way home and tore into it as soon as she was parked on the couch.

She woke up to her stomach rumbling and the smell of pizza.  Elena was sitting in the chair next to the couch, munching on a slice while watching something she was streaming.  She was wearing a crop top and a pair of panties, which was usual for her when she was lounging.  Jamie said nothing as she stretched and grabbed for a slice. She was hungry again.

Elena smiled at Jamie mischievously as she finished her slice.  “You know, I figured I’d be more attracted to you with larger breasts, hon, but damn.  You’re almost as big as I am.  You’re bigger than I was.”  Jamie thought about that.  Elena had been wearing a 38D bra for as long as Jamie had known her.  The look on Elena’s face clued Jamie in.  She wanted Jamie to ask.

Jamie rose to the bait as Elena moved to sit beside her.  “Okay, sweetness.  How big a bra did you grow into?”

Elena slid her arm around Jamie’s waist and snuggled against her.  “I’m up to a 38F, though that’s not all that grew,” Elena explained.  “Not that I’m complaining, but I had to get new panties.  I used to be a size seven, while now I’m up to a size nine.”  Jamie’s panties were a bit snug, too, but she hadn’t thought to check.  “How about you?”

Jamie tugged her top off to reveal her cow print bra.  Elena giggled and mooed before kissing each of Jamie’s breasts.  “34DD,” Jamie said, her voice growing husky as Elena nuzzled her breasts.  On her frame, Jamie’s breasts looked proportionally bigger.  Part of her hoped they’d keep getting bigger.  As Elena nuzzled Jamie’s breasts, her nipples stiffened and her breasts felt tighter, especially near her nipples.  Elena pulled the flaps of the bra away and wrapped her lips around one of Jamie’s nipples.  She bit it gently before beginning to suck on it.  After a moment, there was relief in the pressure.  Elena’s eyes went wide and her lips pp[[ed free of Jamie’s nipple.

“Don’t stop,” Jamie whimpered.

“Jamie, you’re lactating,” Elena exclaimed before returning to sucking the milk from Jamie’s breast.

While part of Jamie rationally thought about the breast pump, having her girlfriend drinking from her felt too good.  The relief of the pressure combined with Elena’s tongue occasionally teasing her nipple was one of the most pleasurable feelings Jamie had ever had.  Her free hand caressed her left breast, which  Elena wasn’t drinking from, and, as her right breast neared emptying, she felt her groin tighten and release, spilling what little cum was in her balls into her panties.

“Mmmm…  dessert,” Elena said lustfully.  She slid between Jamie’s legs and licked the front of Jamie’s panties.  She paused for a moment, looking curiously at Jamie before tugging down Jamie’s panties and licking her clean.  It felt different to Jamie from the times Elena had done it before, but Jamie couldn’t place how.

When she woke up and saw herself in the mirror the next morning, she saw why.

Instead of just her balls, a small indent had formed below her dick.  She touched the indent and moaned.  It wasn’t possible.  Was her body forming a pussy?

Later that day, Jamie got a call from the clinic where the experiment was based.  They needed her to come in that day claiming it wasn’t something they could talk about over the phone.  Jamie checked with her boss.  While it was okay for Jamie to take off early, her boss also let her know that HR wanted to talk with her the next day.  With that hanging over her head, Jamie headed to the clinic.

Instead of the busty nurse Betsy, she was greeted by an equally busty doctor who introduced herself as Doctor Simonsens.

“My apologies for asking you to come in.  Before I go into detail, I need to remind you that you signed a nondisclosure agreement when you entered the study.  What I’m about to discuss with you falls within that agreement.  Do you understand?”

Jamie frowned.  What could it be?  “Okay.  As long as my health isn’t at risk,” Jamie conceded.

The doctor nodded.  “We don’t think so; however there were some anomalies.  You gave us access to your medical records and we cross-referenced those anomalies to your past history, specifically genetics.  When you were born, you were born male with perfectly healthy XY chromosome pairings.”  She turned the screen in the office to show Jamie.  “This is what came up in the tests.

Jamie was confused.  “What am I looking at, doc?”

Doctor Simonsens tapped the screen.  “Right here.  The chromosomes here should be XY.  They’re not.  They’re XX.”  She then clicked on the screen.  “These were your pairings before the drug trial.  We checked them mostly in case something cancerous showed up but this…”

Jamie’s eyes went wide.  “Wait.  Are you telling me that, genetically, I’m a woman?”

The doctor nodded.  “Exactly how, we have no idea.  Nor do we understand the full extent of what will happen to you.  We’d like to monitor you closely for a couple of days at least.”

“But I have a job!  I can’t just take a few days off!”

The doctor bit her lip.  “We’re more than happy to compensate you.  In addition, this is for your own safety.  We don’t want your body rejecting parts of itself and making you ill.”

“Yeah, I guess, but…”

“No buts, Miss Smithe.  I must insist.”

Jamie sighed.  “Let me call my boss to let him know.”  The doctor nodded.

The results of the call weren’t overly unexpected.  Jamie was fired, which was going to happen after meeting with HR anyway.  The reasons were irrelevant and just enough for the company to cover their asses legally.  Jamie wanted to cry but, frankly, she’d started to hate her job anyway.  She texted Elena to let her know what was going on and knew she wouldn’t get a reply for at least a couple of hours.

Back in the room with the doctor, Jamie was required to sign additional forms.  Then came the questions.  “Have you seen any additional changes?” Doctor Simonsens asked.

 “Well, I think I’m growing a pussy,” Jamie explained.  

“Any cramps?”

“Yes, I’ve been having cramps.  They’re more uncomfortable than painful,” Jamie replied.  “Also, I’ve already started lactating and my breasts have been growing.”

“Have you noticed any changes in your sexual orientation?” Doctor Simonsens asked, her tone curious. Jamie was a bit shocked by that.  “We’re in unknown territory, Miss Smithe,” she continued.  “We’ve never had anyone change gender on a genetic level.  We’re only asking for documentation.  If you’d prefer not to answer, it’s fine.”

Jamie thought about it.  While she did want to know what it felt like to be penetrated vaginally, she’s been fucked in the ass by Elena on occasion and enjoyed it.  It was more being attracted and turned on by the female form than the male form.  She didn’t think guys were ugly or attractive.  They were just “guys”.  The idea of them fucking her now that she’d have a pussy neither appealed nor appalled her.  “I won’t say that I’m attracted to men, but I don’t find the idea of sex with men unappealing, either,” Jamie ultimately answered.

“We’d also like to run some tests, namely x-rays, an MRI, and an EKG.  We’ve already run about every blood test we felt should be run.  Also, we’d like to get a sample of your milk,” the doctor explained.

Jamie wasn’t happy about all that, except the milk sample.  She was already overdue for a milking.  “Milking first then everything else.”

“Certainly.”

Her milk production was almost double what it had been two days prior.  Jamie was pleased with that.  The doctor was astonished.

“Almost half a liter per breast!” The doctor exclaimed.  “Are you in any pain or discomfort?”

“Not in my breasts,” Jamie stated, putting the flaps back over her distended nipples.  “Though my nipples are a little sore.  My stomach still feels like it’s in knots.”

“Ah, that I can answer,” the doctor said, pulling up the screen.  “Your body has begun to develop ovaries and a uterus.  Your prostate is completely gone and your testicles might as well be.  Our staff’s endocrinologist recommends you stop taking T-blockers as we expect that your body will be producing the normal amount of hormones for a woman within the next few days.  It’s already making elevated levels of prolactin.  

“There’s also a higher level of the drug we gave you than expected.  We’re not certain why, given we’re the only supplier.  Have you changed your diet at all?”

Jamie shook her head.  “Not that I’m aware of.”

“Well, we’ll keep an eye on you for the next few days.  Do you need to call anyone else?  Is there anything else you need?” Doctor Simonsens asked.

“This is going to sound bad but one thing I’ve noticed the last couple of weeks is I get aroused at the drop of a hat and, if I don’t take care of it, it becomes like an itch that I can’t scratch.  It’s almost a need to find release.”  Jamie blushed.

“And how do you find release?” the doctor asked, her tone more curious than alarmed.

“Milking usually causes me to orgasm, though Elena touching me, especially when she…”  Jamie felt her heart race and her nipples harden.  “When my pussy started to form and she licked the remains of my cock like it was a clit.  It was one of the most intense orgasms of my life.”

Doctor Simonsens looked thoughtful.  “While I can’t have your girlfriend show up to relieve you, I’ll see what I can do.”

Over the next two days, Jamie was routinely poked and prodded, along with the doctors running several tests, including two MRIs.  An OBGYN, Doctor Tailor, was brought in on the second day.  She was patently confused once the exam was finished.  “If you told me that the patient had any type of androgyny, I’d call you a liar.  The only thing even hinting at it are the size and shape of her hips, but, even then, that’s within normals.  Everything else seems perfectly normal for a woman her age, barring her breast size and the fact that she’s producing an abundant amount of milk despite never having been pregnant,” Doctor Tailor explained.

Jamie’s eyes narrowed.  “Perfectly normal?”

Doctor Tailor nodded.  “Admittedly, there is some internals that show significantly atrophied or outrightly missing male biology.  Your urethra has shifted and is now where one would expect to see it on a woman.  If I hadn’t seen your file, I would be hard-pressed to say that, biologically, you were ever anything other than genetically female.”

Jamie blinked at that.  Her mind spun.  “Completely?”  Her hands moved to her belly.  “Does that mean…”

“That you can conceive?” Doctor Tailor prompted.  “Quite possibly; however, given your current medication, I wouldn’t recommend it at this time.”

There was a tap at the door.  Doctor Simonsens walked in a moment later.  “I’m just here to check with Doctor Tailor,” she said with a smile.  “If everything’s okay, you should be good to go and we’ll start prepping for your discharge.”

Elena was waiting for her in the lobby.  A grin played on her lips as she helped Jamie out of the wheelchair.  Jamie kissed her cheek.  “I missed you,” Jamie said.  The look of lust of Jamie’s face caused Elena to blush and her nipples to stiffen.  Elena bit her lip.

“I imagine,” Elena said, her tone teasing as she and Jamie walked to the car.  There was more sway in Jamie’s step than before.  “I do need to stop at one place before we go home.”

“Do tell,” Jamie said, slipping into the car.  She struggled to pull the seat belt across her large breasts.  She hadn’t been able to wear a bra as she left the hospital.  The one she’d worn there simply wouldn’t fit.

“Inga’s Intimates,” Elena said with a smile, starting the car.  “I’m guessing you will, too.”

Jamie nodded.  “The clinic dropped off a stipend and a bonus about twenty minutes ago.”

Elena’s eyes widened at that.  “A bonus?”

Jamie nodded.  "I’m producing almost two liters of milk a day.  They gave me a calcium supplement and told me to stay hydrated.”  Jamie cupped her large breasts.  “I can’t wait to find out how big I am now.”

Ten minutes later, the pair pulled up to a small store near downtown and walked in.  The woman at the register gawked for a moment then snapped her mouth shut.  “Welcome to Inga’s,” she said.  Her name tag read “Mary”.  “Let me know if I can help with anything.”

“Truth be told,” Jamie drawled, “my girlfriend and I seem to be going through a growth spurt.  We both need new bras, preferably maternity.”

Mary’s eyes widened, presuming the most likely scenario.  “Well, congratulations to you both.  If you’ll step into the back, I can get you both measured.”

Five minutes later, both Jamie and Elena were astonished.  Jamie had gone from a 34DD four days before and now needed a 34H bra.  She’d grown half again as large as she had been.  Elena’s breasts had similarly swelled, though more so.  Her breasts had increased from F-cups to J-cups.  

Mary was astonished. “We do have bras in those sizes, but much bigger and we’ll have to order them.”

Jamie smiled at that.  She hoped she kept growing.  Aside from a small amount of back pain, she loved how huge her breasts had gotten.  They hardly sagged, though Jamie wondered how much of that was due to how much milk was in them.  Still, once she got a new bra and put it on, that helped support her girls, which decreased the amount of back pain she’d felt.  Elena expressed similar thoughts.  They picked up two bras each, expecting they’d likely outgrow them.

The pair left Inga’s, promising to stop by if they needed new bras.  Getting into the car, the pair hurried home.  Jamie’s breasts were beginning to ache: a sure sign she needed to be milked.  

The pair were naked within minutes of getting inside.  Moments later, Elena was sucking on Jamie’s left breast while fingering her clit.  Jamie hadn’t been able to discretely orgasm for the last few days so it didn’t take long for Elena to bring her to climax.  The feeling crashed through her whole body, unlike before when it had centered on her crotch.  When Elena moved from Jamie’s nipple to Jamie’s pussy, Jamie mooed in pleasure, causing Elena to giggle.

“You should pump your other udder, cow, while I make up for the last few days,” Elena said before lapping up and down Jamie’s pussy lips.

Jamie reached for the other breast pump she used that she kept on the nightstand and moved it to her left breast.  She moaned as the pump started working.  Elena’s smile was hidden as she flicked her tongue against Jamie’s clit.  While Elena didn’t see herself as a cow, Jamie’s mooing had become a turn-on in and of itself.  She planned to see if she could get Jamie to submit to her later.  “After,” Elena thought, “I’ve all but worn her out first.”

The next morning, Elena woke to the sound of Jamie pumping her breasts.  Elena’s breasts ached as well and the sound of the pumping caused her milk to leak from her nipples in anticipation.  She shifted the blanket from her body and made her way to the bathroom, using the facilities before taking a quick shower.  The spray against her breasts caused them to throb.  Elena was tempted to milk herself in the shower.  She knew that the pumps would feel better.

Drying herself off, Elena slipped on a pink nursing bra and a pair of matching panties before making her way to the living room.  Jamie was sitting on the couch in a pair of cow print panties and a matching nursing bra, pumping milk from both of her breasts.  Her eyes were half-closed.

“Need help with that, cow,” Elena teased.

“Moo,” responded Jamie before giggling.  “You know, I was thinking.  I’m a bit overdue for a trim and a mani-pedi.  Care to join me later?”

Elena reached into the hall closet and grabbed her own breast pumps before sitting on the recliner next to the couch.  “Hmm… A mani-pedi does sound nice.”  She opened the flaps of her nursing bra and adjusted one cup of the pumps against her left nipple, turning the pump on before repeating the process on her right nipple.  She sighed in relief as her milk began to be sucked into the bottles.  She looked up as Jamie stood up.  “Done already?”

Jamie blushed.  ‘Um, no.  This is the second time I’ve had to empty the bottles this morning.  You didn’t wake when I had to get up to pump last night.”

“Last night?  Jamie, hon, how often do you need to pump?”  Elena was shocked.

“About every three hours,” Jamie said, looking at the floor and past her leaking nipples.  “Also, I kinda lied when I said two liters the other day.  I didn’t want to scare you.”

“Scare me?” Elena asked, her eyes wide.  “How much, Jamie?”

“Three liters, though that was yesterday,” Jamie admitted, biting her lip.  “I keep wondering how much I’ll produce once I stop growing.”

Elena’s eyes narrowed.  “You don’t want to stop growing, do you?”

Jamie looked away for a moment then back at Elena.  “I do have a point that I think is too big, but not before then.  I’m close.”  Jamie hefted her volleyball-sized boobs.  “Given how much they swell with milk, it won’t take much before I’m too big if I don’t pump regularly.”

Elena giggled.  “Well, cow, you better keep pumping.  You’re leaking on the floor.”

Jamie blushed and hurried to the kitchen to pour the milk into a jug which then went into the fridge.  She returned with the pumps against her breasts and sat back down.  Elena had turned the TV on and had moved over to the couch.  Jamie sat beside her.

After a while, the pair had finished pumping.  With no other plans for the day, the pair got dressed.  Jamie put on a knee-length pink skirt and a pink tee while Elena put on a pair of stretch pants, a white tee, and a cream blouse.  Both wore black pumps.  They made their way to Elena’s car and headed to get mani-pedis, something they often did as a couple.

Just under an hour later, they both headed to Sophie’s Salon to get their hair done.  To Elena’s surprise, Jamie asked to get her hair bleached.  “Are you sure?” Elena asked.

“I had a dream last night,” Jamie said.  She felt her cheeks blush as she recalled the dream.  She’d woke up with her fingers in her pussy, but she wasn’t going to tell Elena that.  “In it, I was blond and you were… ahem… helping me with…” Jamie glanced down at her breasts.  “It felt so real, I wanted to make it real.”

Elena smiled.  While she was naturally blond, she had wondered what Jamie would look like as a blond, too.  “Well, if you’re sure.”

Between the trim and the bleaching, it was almost an hour before a now blond Jamie was ready to go.  She was wincing a bit as the pair left.  “You okay, sweetie?” Elena asked.

“My udders are in need of attention,” Jamie said as she got in the car.  Elena giggled. “What?”

“You just called your breasts ‘udders’, silly cow,” Elena noted as she pulled the cow out of the parking lot.

“Well, I am a cow and cows have udders, not breasts, moo,” Jamie said.  She grinned.  “Does that make you my owner?”

Elena almost ran a red light as what Jamie said donned on her.  She turned right, making a decision.  “Not yet, but I will be after we get home.”

Jamie frowned.  “Then why did you turn right?  Home’s back that way.”

“You’ll see.”

Elena pulled into Tammy’s Toybox.  “You are to stay here, cow,” Elena ordered before opening her door.

“Yes, ma’am,” Jamie replied, curious as to what Elena was here to get.  Ten minutes later, Elena walked out with a discrete brown paper bag and put it in the trunk.  Ten minutes later, Elena pulled up to their apartment.

Once inside, Elena set the bag on the coffee table.  Jamie was taking off her tee when Elena playful smacked her hand.  “Pets do not dress and undress themselves.  Only their owners do that.”  She then tugged Jamie’s t-shirt up over her head.  She also helped Jamie out of her skirt, leaving Jamie in her bra and panties.

Elena took Jamie’s hand and led her to the couch.  “Be a good girl and wait here.  It’s time for me to milk you, cow,” Elena said with a smile.  Jamie watched Elena as she got Jamie’s pumps, opened the flaps on Jamie’s nursing bra, and set the cups of the pumps against Jamie’s gumdrop nipples.  “Hold these for a moment, pet,” Elena ordered.  Jamie held the pumps in place as Elena moved the other end of the couch.  

Jamie wanted to giggle.  Normally, she was the big spoon but it was obvious that Elena wanted to be the big spoon this time.  Jamie wiggled over so that her back was to Elena’s front.  Elena turned the pumps on and moved her hands to hold the pumps against Jamie’s breasts.  “Such a good cow,” Elena said before kissing Jamie’s neck.  “If you’re determined to be a cow, let’s get you milked while I tell you the rules.”

“While you are being milked, you are my cow,” Elena began.  “You will wear what I put on you, even if that’s nothing at all.  You will address me as Mistress Elena or ma’am.  You will do as I tell you, though there’s one exception.”

“What’s that, Mistress?” Jamie asked.  Her mind was in a haze from the pleasure of being milked.

“Cows are animals and animals will pleasure themselves when they feel the need,” Elena stated.  She wanted to see if Jamie would do as she suggested.

“Like this, Mistress?” Jamie asked.  Her hand slid down her panties to her pussy, spreading her wet lips and finding her clit.  She began to slowly tease herself.

“Yes, pet; however, you may not cum without my permission,” Elena added.

“Yes, Mistress, moo,” Jamie said, her eyes dropping closed.  One thing Jamie had to admit about her fully female body was the ability to edge for so much longer than as a man.  Jamie was so engrossed in pleasuring her own body that it took the sting of the pumps trying to draw out milk that wasn’t there before she stopped playing with her clit.  “Mistress, my udders are empty, moo.”

“Then let me up, cow,” Elena said.

Jamie moved to stand as Elena shifted on the couch.  Elena had turned off the pumps and held the pumps for Jamie to take, which she did.  Elena stood and took the pumps back, taking them to empty them into bottles before placing the bottles in the fridge.  She returned and shifted Jamie so that her back was facing Elena.  

Elena unhooked Jamie’s bra and slid it down her arms.  “You won’t be needing this for the rest of the day, cow,” Elena said with a smile.  She then also took off Jamie’s panties which were damp from Jamie’s playing with herself.  “Now be a good girl and go wait in bed for me.”

Jamie walked from the living room to their bedroom, her hips and “udders” swaying back and forth.  She laid down in bed, spreading her legs, her hand going back to her pussy, rubbing and teasing herself.

Elena walked in with the paper bag and a jar of Moomoo Balm.  She smiled at Elena as she set the jar and bag on the nightstand.  She then took off her clothes except for her panties.  Grabbing the jar, she put a little bit of the lilac-scented balm on her fingers and began to rub it into Jamie’s breasts.  Jamie mooed in pleasure.  “Like that, do you, my pretty cow?” Elena teased.  Jamie nodded.  “Well, since you’ve been a good girl, it’s time for cow’s owner to reward her.”

“But Mistress already milked me, moo.  That felt so good,” Jamie said.  “And my pussy is so wet.  Cow just wants to cum, Mistress.”

“I know you do, cow.  But people get fucked like this.  Cows get fucked on all fours.”

Jamie’s eyes widened.  It took her a moment, given the size of her chest, to roll over onto all fours, her nipples brushing the sheets, her head facing the headboard.  She felt Elena slide off the bed and then watched her grab the paper bag.  After a moment of rustling, she felt Elena slide onto the bed behind her and something rubbing against her pussy lips.  Jamie felt one hand on her left hip.

Elena laughed.  “And to think, I used to complain about waiting for you to fuck me this way.  No wonder you were so worn out after.”  As she said that, she slowly pressed the head of the strap-on into Jamie’s pussy until she met resistance.  Jamie froze.  Elena caressed Jamie’s backside.  “This is going to hurt for a moment, cow, but then it will feel better.  I promise.”

Jamie sucked on her lip as Elena penetrated her virginity.  Elena had been right.  For a moment, the pain throbbed and Elena didn’t move, letting Jamie relax.  Taking in several slow breaths, Jamie began to rock slowly.   The feeling of fullness was wonderful.

“It’s not too big is it, Jamie?”

Jamie realized that Elena must be very concerned if she wasn’t calling her “pet”.  “No, Mistress.  It feels so full and good.  Please, fuck your cow, moo,” Jamie pleaded.

At first, Elena was awkward as she rocked her hips.  She’d never been the one fucking someone else.  Jamie had always done that.  After a minute, the pair got into a rhythm.  Jamie mooed in pleasure.

“Please, Mistress.  Please can cow cum?” Jamie begged.  She could feel her climax nearing.  “I’ve been a good cow, moo.”

“Only if you promise to make your Mistress cum after,” Elena teased, smacking Jamie’s ass.

“Anything, Mistress.  Feels so good, moo.”

“Then cum for me, cow.”

Jamie’s pussy clenched around the strap-on dildo as her orgasm overtook her.  She mooed loudly.

Elena moved back as Jamie slid to her side.  Sliding off the bed, she wiped the dildo clean and slid the strap-on off her hips along with her panties.  Jamie continued to roll over which allowed Elena to straddle her face.  Jamie knew just how to wring out every ounce of pleasure with her tongue and it wasn’t long before Elena came as well.

Two weeks later…

“They hired me!”

Elena looked up from her computer.  Jamie was standing there wearing just a T-shirt and panties, her nipples poking through the shirt.  Her breasts had finally stopped growing a few days before while Elena’s hadn’t grown in over a week.  Jamie’s breasts were as large as basketballs.  Jamie’s nipples, just after pumping, were the size of strawberries and just as red.  Elena’s breasts had stopped growing at J-cups while Jamie’s were impressive M-cups. The clinic had been gracious enough to pay for custom bras for Jamie.

“Who hired you?” Elena asked.

“The clinic.  They needed someone to work in their marketing department, though I get to spend whatever time I need to milk my udders.” Jamie explained.  “You should see the pumps they have.  I’m also not the only ‘cow’, there.  One of the secretaries, Stephanie, has udders almost as big as mine.”

Elena smiled.  “Almost, but not quite, right?” She stood and walked over.  Her hands moved to Jamie’s breasts, caressing them.  “I wouldn’t want you to be anything less than the best cow.”

“Moo.”

Elena giggled.  “Such a good cow.”

“But Mistress, they did offer me a choice,” Jamie noted.  “They think my body can handle growing even more.  If I agree, I’d get to spend the day producing milk while I got to stream or surf to my heart’s content.  They’d be able to sell my milk to mothers to feed their babies.”

Elena arched an eyebrow.  “They gave you a choice?  Wait, Jamie.  Don’t tell me.”

Jamie nodded.  “I accepted.  I already took the booster.  They sent me a set of pumps to pump at home and a milking bench. Are you okay with this, Mistress?”

Elena traced her fingers through Jamie’s hair and smiled.  “Silly cow.  Of course, I’m okay with this.”  Jamie nuzzled Elena’s hand.  “Aren’t you glad we signed up for that study?  Now, let’s test out those new pumps.”
