Dream Vacation

"You won't believe it, honey\!" Mary cried, checking over the piece of paper one more time as she stood in the doorway, the morning sun pouring over her body like liquid gold.

Rob came out of the kitchen, morning coffee in hand, just waking up from a hard week at the office.

"What is it, babe?" He asked. 'Babe' was a hangover from when their relationship had been a lot more…physical than it was now. He still liked to use it, but the time when he felt like she was a babe – and she, him – had long passed.

"This competition\! We just won our Dream Vacation\!" Mary was thrilled, her short dark hair shaking back and forth as she jumped for joy. Rob hadn't seen her this animated in years. He liked it. It reminded him of when they were younger. He still absolutely loved his wife, more than anything in the world, but their sex life since they'd had little Josh had gotten…well, "stale" was an understatement. They barely had sex at all these days. They were so tired from just living that they didn't always feel like they were alive.

"Huh." Murmured Rob, taking the envelope and running his eyes over the document. The prose was very excitable, but it did indeed seem like they'd won some kind of vacation. "Strange, I don't remember entering this. Was this you?"

Mary giggled, shrugging girlishly. Rob smiled at her play acting. "I don't know…I guess so? I enter a lot of this kind of thing." She grinned, grabbing the paper back, and checking it over with shining eyes. "So I guess it must have been me\!"

Rob smiled, taking a slug of morning coffee, feeling the energy slowly moving through him. This was weird, but it was early in the day, he was tired and also it was a free freakin' holiday. There was no denying they could both do with it.

"Guess I'll book in the babysitter, we're going on vacation\!"

Mary laughed and hugged him, staring up at him with shining eyes. He looked back, feeling like this was going to be a good trip.

The plane drifted low and lazily over the island below. No one had been able to tell Mary or Rob exactly where this place was, but it was somewhere tropical and as Rob leaned over Mary to press his nose against the window he could see sandy beaches, blue oceans and palm trees, and that was enough for him. It looked like paradise.

Also, though he was trying very hard not to notice, a lot of people on the plane were noticeably busty. The flight attendants all had very impressive racks, stuffed into their tight uniforms and blouses, which looked like they were going to pop open if they so much as breathed too deeply, but also a surprising number of the passengers had impressive chests. The woman on the other side of Rob had a very large pair of what looked like implants, stuffing her vest top with a deep and delicious array of cleavage that it took all of Rob's resolve not to stare at with a thirsty longing.

He didn't want Mary to notice, of course. She had small, modest b-cup breasts that looked ok with a push-up bra, but – and here was the issue – she wasn't hugely in touch with her sexuality. Neither was Rob, to be fair, so they never really explored their desires. They'd had sex, of course, a plenty of it, but never anything very experimental – both their innermost lusts were kept under lock and key, and the fact that Rob was very turned on by these large-breasted women was something he tried very hard to keep to himself.

Mary was no fool, though. She saw him looking, saw him lusting, and the seeds of doubt and insecurity were sown in her mind. They were already there, of course – Mary had observed his desire for big tits on and off over the years, but she'd never had the kind of time and energy they both did now to notice it, and to properly acknowledge it. And with every bulging pair of breasts and heaving cleavage that Rob's eyes glanced at, before flicking guiltily away, her feelings of inferiority grew.

When the plane landed, the woman next to Rob stood up to get her bag from the overhead compartment, and the sheer scale of her giant breasts was unveiled to him, swelling out like massive melons. Rob's mouth went dry as he tried not to look as she stretched upwards to grab her bag, her shirt almost bursting off her giant chest as her balloon boobs warped the material. Rob grew painfully hard, and shifted in his seat to try and avoid looking like he had such an obvious boner.

Mary frowned as she turned away from the scene, looking out from the small plane onto the landing strip, cheered by the luxury resort sitting not far away from the tiny airport on this gorgeous island paradise. Hopefully these big-titted bimbos were all going to be elsewhere, in some slutty hotel for Hooters employees, Mary thought to herself, as she got up, grabbing her bags, making for the exit.

\\

After a short taxi drive, where the gorgeous views of the island took Mary's mind off the huge tits that apparently so enamored her darling husband, they pulled up to the front of the hotel. There wasn't much else on this island, apart from some farms in the distance. Horses, Mary hoped. Everything else was beaches and palm trees – sun, sea and sand. Deep down, Mary kind of hoped for sex as well – things had been so dry for so long, she was craving some cock. Rob was a good husband, and a good man, but he hadn't serviced her for such a long time, she was going round the bend. Maybe if she had bigger tits, he'd be fucking her more. The thought made her equal parts annoyed and turned on. He would have to be satisfied with what he had – and so did she\! It wasn't like Rob was some Adonis who could have anyone he wanted – he'd let himself go since they'd got married and had kids, just like she had. Life was hard, it always got in the way. At least she wasn't drooling over every muscle-bound hunk with a massive cock that strode across her path.

That got her imagination firing, and she had to shake her head to remove the image of Rob with a huge dick and massive muscles from her mind's eye. It was time to relax, not indulge in every idle thought that came into her mind. And so their lusts were pushed back down, held in the subconscious where they belonged. And where both halves of the couple hoped they would stay…

\\

The resort turned out to be absolutely stunning – they were only there for the weekend, as per the terms of the competition, but it looked like they would be able to have a great stay in that time. They were checked into their room from an impressive, marble reception, by a very handsome bellhop who looked like he had an impressive figure under all that uniform. Mary found the longer she stayed here, the more she allowed her mind to wander. It wasn't like it was going to do her any harm, either. Also, Rob had looked at the busty receptionist with her tight blouse, buttons straining once again to contain her considerable breasts, and Mary had felt a pang of jealousy. So if he wasn't going to restrain himself, then neither would she.

Their room was huge, a massive, king-sized bed with huge windows that looked down over the beach, and a large, marble bathroom, with a huge bath and shower unit. Mary loved the feeling of the cool marble under her feet, and looked at the large white bath robe with a sense of deep relaxation and desire. She was surprisingly horny, given she'd just gotten off a big flight. Though the fact that she hadn't had sex or rubbed one out for months was probably a fairly substantial contributing factor.

"Hey hubby." She smiled, walking back into the bedroom to find Rob unpacking his suitcase, his back to her.

"Hey babe." He smiled, pecking her on the cheek as she leaned in to embrace him.

They kissed, a little awkwardly, but it still felt nice to have the human contact. Mary was acutely aware the passion wasn't exactly raging, but that was just the way it was. Maybe they just needed some loosening up?

"Hey, how about we grab a drink?" Mary suggested, hoping a little booze would lead to some holiday action.

"Sounds great." Rob smiled.

\\

As soon as they stepped into the bar, Mary knew she'd made a terrible mistake.

"Good evening, like, how can I help you guys?" Smiled the blonde barmaid.

"For fuck's sake." Mary whispered under her breath as she eyed the huge pair of tits rising up and down on this bimbo's slender frame. They were stuffed inside another tight button blouse, with a waistcoat impossibly strapped over them. The effect was of an outfit that looked like it was at least two sizes too small, which only served to accentuate her giant rack and narrow waist. Rob's eyes practically popped out of his head.

"I'll grab a beer." He smiled, sidling up the bar, grinning easily, his gut resting on the counter as he sat on a stool.

Mary sat next to him, looking at this blonde beauty as she poured the beer, her teeth perfectly white, her long blonde hair immaculate, her make up beautifully applied, her breasts large and succulent, bursting forth from their tight prison. Mary tried not to think about it, but she found this idiot irritatingly sexy.

"So, like, what do you do?" The bimbo continued, almost knocking over a stack of glasses with her bouncing rack.

"I'm a professor, he's an accountant." Mary replied primly, taking her own seat, drawing attention away from the woman whose large, plump breasts had so enraptured her husband.

"Oh cool, so you're, like, super smart."

It wasn't a question, but the woman's voice raised a little at the end of the sentence, suggesting a certain doubt in what she was saying. It made Mary's blood boil.

"I am, as it happens." (and you wouldn't catch me working bar) she didn't say. But how she wanted to. She knew it would just piss off Rob, and ruin any chance they had of sex, so she held her tongue.

"Chemistry, since you asked. And I'll have a gin and tonic. You know what – make it a double."

"Like, cool." The woman smiled, turning her bountiful breasts to Mary, preparing her drink and placing it in front of her. Her tits almost pressed into the beer taps, and Mary found herself wanting the bartender with the big breasts to lean forwards, rubbing them on the taps, giving them a little tit-fucking, allowing the condensation to get her shirt nice and wet, making her nipples hard and ready to fuck-

"What do you think, babe?" Rob was asking, and Mary blushed, realizing she had completely zoned out, thinking about this woman's giant rack.

"About what?" Mary asked, her focus pulling back to the room.

"What's the best Avengers movie? Crystal loves 'em." Rob smiled, gesturing over to the pair of breasts on legs who had just pulled out some gum and started chewing.

"Of course Crystal does." Mary smiled, with no joy in her words. "Another G\&T please. Make it a" – she looked at Crystal's heaving chest, which was rising up and down with every breath she took, look like it was going to burst a button any second – "large."

\\

Mary slept fitfully that night. She was drunk, for a start, and she barely drank these days, but also thoughts of this strange, busty resort full of big-titted bimbos flooded her mind, causing her to feel strange, lusty feelings that she knew she ought not to, and chief of them all was the huge pair of tits strapped to Crystal, tits that Mary knew Rob idolized, and that deep down she wanted for herself. But it was so hard to admit it, so hard to say that she wanted to big a big-breasted bimbo whose hardest challenge in life was to rank superhero movies.

Mary tossed and turned in the room. It was cooled by a state-of-the-art air conditioning system, but even so she was hot. Her body felt sweaty and prickly, and so very, very horny. All her desires were bubbling inside her, and she felt herself wanting cock so badly she didn't know what to do. Maybe she just needed to be a bit more like Crystal. Less demanding, more sexual. In her sleep-addled state, Mary imagined them as one and the same, Crystal's large, full breasts on her flat, plump frame, and she imagined her body changing, and that Rob wanted to shove his dick inside her again and again.

And before she knew it, she was awake and on top of Rob, who she was imagining as the muscular bellhop from yesterday, and she was whispering for him to wake up.

"Like, I want your cock, Robbie." She never called him Robbie. Her jaw moved a little, like she was chewing gum.

He opened his eyes with a grunt, to see his wife on top of him, wearing a snug vest top and little shorts, all of which seemed a little small for her, and he immediately grew hard at the suggestion of secret night sex. It had been a long time for him as well.

"You look great." He murmured, unable to see his wife properly in the dim light, but aware that a curvy beauty was on top of him, her supple body bulging in all the right places. He ran his hands over her tits, and loved how large and full they felt. It didn't make sense, but Rob was almost asleep, and this felt too good to argue with. Mary moaned, placing his hands over her breasts, which she thought were larger than she remembered, but were, like, nowhere near as big as Crystal's, which was the size she wanted.

She ran her hands over Rob's body, finding it more toned than she was used to, which was somehow what she expected. This was the vacation of dreams, after all, so it was only natural that she was enjoying hers. And in this dream, she wanted her breasts bigger, as big as Crystal's, the huge tits that her husband was enjoying. She wanted those breasts, wanted her husband's attention, and so she imagined it so. She imagined her breasts growing larger, slowly swelling bigger and bigger, filling up and out, growing out on her chest, stretching outwards, stuffing her vest top, creating a luscious dip of cleavage, thick and inviting enough for a big cock to slide between.

She moved down onto Rob's crotch, pulling off his underwear, which felt surprisingly snug over his average-sized dick, and was surprised to see how substantial it felt in her hands. He moaned as she kissed and licked it, and then grunted in pleasure as she took him in her mouth, somehow getting the whole big shaft inside her throat, sliding up and down and guzzling on that meaty shaft. And, because she dreamed it, she made her breasts grow all the time, insisting that they expand to be as big as Crystal's. No, bigger. And they did grow, bulging outwards, pressing into Rob's legs as they expanded, large and swollen and heavy, until they were big enough: engorged DDs ready to envelope Rob's cock.

And then she removed his dick from her mouth, and slid it between her breasts, tit fucking him like she'd been doing it all her life, even though this was the first time she ever had breasts large enough to do. And her brain felt all strange and fuzzy, like there was stuff that didn't make sense, but then she realized how good it felt to have this large cock pinned between her large tits, which were gripping it tighter and tighter as they expanded, and Mary knew she wanted her breasts to be huge to please her man, because he had a large dick, so it only made sense that she had large breasts, and then as she moaned with pleasure as her breasts swelled to even larger, heavier heights, Rob grunted with bestial desire as his cock exploded with cum, the hot, thick load splashing all over Mary's big new breasts. She purred with contentment, releasing the dick from its fleshy prison, and rubbing the cum over her boobs. She was dimly aware her breasts were much, much bigger than she was used to, but it didn't really seem like a problem. She was a smart woman with a PHD, she could figure out what was going on in the morning. For now, it was time to enjoy the cum on her fat tits and get some sleep. For some reason she was exhausted. But very satisfied, and very, very happy.

And this time, when Mary went to sleep, she didn't dream.

Mary awoke with a yawn and a stretch, her arms accidentally bumping into Rob. He groaned in bed, and turned away, and Mary rolled onto her back, where she suddenly felt pressure on her chest, like it was slightly hard to breathe.

Her head felt fuzzy, probably from all the gin she drank last night, and thinking was more difficult than she was used to. What had happened last night? She remembered some gorgeous big-titted blonde at the bar, and then confusing feelings came up in her mind. She was jealous of that woman, because that woman had big tits, but then she felt the weight on her chest, and when she looked down, observing the mass of cleavage lying heavy on her, she knew she had no reason to be jealous – she had a fantastic pair of DD breasts that fit her slim frame perfectly. Tits that Rob loved, and had always loved. So why did she feel jealousy?

Mixed among those feelings, which were getting increasingly difficult to parse as Mary's brain swam, warm and fuzzy in the cool early morning, air-conditioned air, her head throbbing a little from all the booze, mixed among all those feelings was a deep and primal lust that coursed through her veins. It was lust for her husband, but also for this woman's figure, for the slim body and huge tits she demonstrated. Not that she was very different from Mary, with her large boobs that she loved to play with so much.

All this talk was getting Mary very horny indeed. Also she'd worn some of her old clothes to bed, because her vest top was incredibly tight around her large, round breasts. They were crammed in, her rock hard nipples poking through the fabric, enticing Mary to reach down and tweak them, moaning with pleasure, her cunt convulsing with arousal as she did so. She needed cock, right now. Her mind was foggy and confused, but that much she did know.

"Morning." She purred, leaning over, her large breasts bulging into Rob's back, who grunted a little as he rolled back into her. Mary loved how her breasts blobbed into her as he pressed against her, creating insane cleavage as they pressed together, as if she was wearing a corset. She loved having big tits. It was so sexy, and Rob loved them almost as much as she did.

"Hey babe." He murmured, and when Mary expected to see Rob's pudgy body as he turned over, instead she was met with a slim, toned physique that was very appealing indeed. Mary's brain struggled to process the cognitive dissonance. Why had she been expected Rob to look pudgy? He was her fit, toned husband – he'd always been that way, hadn't he? Just like she'd always had these luscious, large breasts. And as she thought about how gorgeous her breasts were, she straddled Rob, who was now very much awake, if the power in his cock was anything to go by, and leaned down to kiss him on the mouth. Her breasts slipped out of her top, too large to be contained, and rested on his chest. She lowered one huge tit into Rob's mouth, and he sucked on it, teasing her bullet nipples with his tongue.

"Fuck me, lover boy." She whispered. Rob replied with a silent smile.

\\

Feeling the warm, gentle post-coital afterglow in every inch of their bodies, Mary and Rob went down to breakfast, their slim, powerful bodies matching up far more with the general size and shape of the denizens of the hotel. Mary found Rob looked far less at other women than she had assumed he would, and she knew that was because she looked amazing, and he had only eyes for her.

Unfortunately, she must have forgotten to pack her clothes properly, because everything in her closet was a bit snug on her. Her bras were almost comically small, every one she tried to wear bulged her breasts up like she was wearing something about 4 cup sizes too small. She tried to loosen them up to their largest size, but even then they were too tight and painful to wear. Her breasts were simply too big. Fortunately, Mary's boobs were so pert, round and firm that she didn't really need a bra. They didn't look fake, but they did look massive. They were so large and round that they rested comfortably on her chest, so she decided to forego a bra. All her tops were mysteriously too small on her, and Mary just couldn't for the life of her figure out why. She knew she was a smart woman with a PHD in something – though she couldn't for the life of her remember what – and sure she may look like big-titted bimbo with these gorgeous breasts, but she had no idea why she didn't have clothes that fit her size. She must have just packed a bunch of old clothes when they went last-minute on this trip. Either that or her tits magically grew overnight\! Mary giggled at the thought, her large chest shaking from side to side. She immediately grew wet, and had to control herself, given she was in public.

Mary tried a bunch of outfits on, but all her tops were just too small for her substantial breasts. She couldn't believe she was silly enough to bring all these small items, so instead she decided to lean in to her situation, and squeeze her boobs into a tight tee. Her impressive chest stretched out her top massively, and her two orbs looked absolutely delicious trapped behind the cotton prison. The tightness of the top kept her pert breasts up, giving them even more lift. She looked incredibly good, Mary had to admit. Rob certainly couldn't take his eyes off her.

She found wearing her jeans was a challenge, too. They must have shrunk in the wash, because when she tried to squeeze her ass into them, she almost busted the fly trying to do them up. She managed it in the end, but her thick thighs and impressive ass absolutely stuffed them to the brim. It meant she walked with a bit of waddle, afraid of bursting her clothes apart at the seams, but it did mean she looked incredible, and Rob certainly didn't seem to mind. He had his hands all over her at all times, having to resist tweaking her large, round nipples, instead settling for resting his hand over her giant ass cheeks, which were stuffing her jeans to the max.

Mary sat down at the breakfast bar and heard a "pop". She knew some of the seams in her jeans had burst, and part of her wasn't surprised. She had memories in her mind of this happening before – she knew she had a massive butt and thighs, giving her, along with her substantial breasts, a perfect, curvy hourglass figure – but she was surprised she hadn't planned for it. Maybe she had a spare pair upstairs she could change into. She rested her breasts on the table, glad to have a short break from supporting them. They were so delectable, she had to resist grabbing them with both hands. Why was she not used to having such big tits? Mary wasn't able to answer this simple question – something in her was delighted about how large her chest was, even though as far as she could remember, she'd had this impressive rack since the end of puberty. The mind was a funny thing.

"Would you get me some food, darling? My jeans have gone again. And I'm hungry."

"I'm not surprised." Rob smiled, his stomach flat and toned in his slim-fit tee. If anything, Rob seemed to have the opposite problem to Mary, in that his clothes all looked a little big on him. Where hers were starting to look a little painted on, they were so tight, his were loose over her slim frame. His tee and shorts looked like those designed for a much larger, chubbier man, and with Rob's svelte figure they almost looked…baggy. That was fine, Mary loved how toned her husband was – she couldn't wait to enjoy his body again, once she'd stuffed hers with food – she was so hungry\!

After a delicious breakfast where Mary only got a little bit of food mess on her large breasts, which for some reason she just wasn't getting the hang of dealing with this morning, they pulled up from the table, Mary tottering a little, her jeans so tight across her gorgeous thighs and ass, threatening to burst open even further, and waddled back to their room. Her breasts felt so full and tight, reflecting her clothes that clung to her impressive form, so Mary demanded that Rob suck on her tits, and immediately pulled him into bed. Before doing that though, she teased him by bending fully over in her tight jeans, ripping a hole clean through the backs of them, her bulging flesh pouring through the gaps. Rob drooled at his large, beautiful, engorged wife, and tore the rest of the clothes off her, throwing her down on the bed, which creaked and groaned under the weight, and they made passionate love, coming together with twin moans of pleasure.

\\

"After that I think I need a dip in the ocean." Mary smiled, kissing Rob once more and hauling herself to her feet. For some reason her body just felt very heavy and immobile today, like she wasn't used to it. It made no sense, but to be honest, the fuzziness in her brain hadn't subsided, so she wasn't able to focus on anything for too long. Her main thoughts were taken up with her handsome hubby and her luscious rack.

"Sounds prefect." Rob smiled, rinsing himself off in the shower and then slipping into some too-large swimming shorts.

Mary decided to get changed straight away, because the naughty, slutty part of her liked strolling around the place with Rob's cum still inside her. She felt like she could feel it sloshing around inside her, though her breasts were so heavy and full maybe it was them that were sloshing. Mary dimly found herself wondering what it would be like to have huge, milk-filled titties, the liquid sloshing around inside her stuffed, engorged globes. Then she shook her head, and the thought went away. Her mind was doing funny things on this trip. But the residual sexiness of that image stayed, even as her thoughts wandered on.

She grabbed a bikini from the wardrobe, but once again Mary found it lacking in the size department. Luckily, she could adjust the length of the ties to give her large breasts a bit more space to move, but the simple fact was that her breasts were far too big to be covered by the triangles of fabric. It was kind of embarrassing that she'd bought something so small, but Mary had to assume it was an old one from before she was fully grown. It was all she had, so it'd have to do. She squeezed her breasts into it, the large amounts of pale flesh spilling out either side, but at least her rock hard nipples were covered. Mary loved looking at her large spread of boobs, how far they emerged from her body, how small all her clothes felt on her. That was how to feel big, she mused – just buy clothes that are too small for you\!

Her bikini bottoms barely fit around her thick thighs and large ass cheeks, and ended up getting almost entirely swallowed by her bulbous butt, but at least she was technically covered, and wouldn't arouse too much suspicion.

She grabbed a towel, threw her arm around Rob, her breasts bulging into him, and together they walked down to the beach.

The sun was blazing when they arrived, and the ocean had never looked more inviting. They parked up under a large umbrella, and took two deck chairs, lying down in the warm shade. The beach was reasonably sparsely populated, just a small group of men and a couple who were talking a giggling, lying there in the sun.

"Hey, would you do my back?" Mary asked, reaching into the beach bag to grab the lotion. Her breasts bulged into her legs as she did this, sending a visceral thrill through her body. When she came back up with the lotion, she saw Rob staring out to the beach. She followed his gaze, a deep pit opening up in her stomach. What was he looking at that was more important than her?

And then she saw. The couple who were lying in the sun laughed and turned, and Mary saw that the blonde woman had the largest pair of breasts she had ever seen. Forget the barmaid last night – her tiny tits were chump change compared to these mammoth milkers. They erupted from this woman's otherwise slender form like mountains, stuffing her large pink bikini to the max, making it look like it was going to burst open any moment. They were implants, clearly, from the way that they stood out from her chest like zeppelins. They were absolutely enormous, and as the man she was with began making out with the busty bimbo and caressing those incredible, massive tits, she could see Rob's large cock tenting in his shorts. Everything fell into place in that moment, and Mary knew that even her large tits weren't enough for Rob. She'd always felt like there was something wrong, deep down, with their relationship, and now she knew – she wanted him to look at her paltry form with the same lust he reserved for these truly titanic tits. She marvelled at their scale, their massive, full, fake roundness constantly getting in the way of what she was trying to do. She almost bumped over the drink she had resting on the table when she turned, her huge hanging knockers almost like udders on her otherwise slim frame.

And Rob was staring at this hugely busty bimbo with the blonde hair and the bolted-on tits like she was the sexiest woman in the world. And Mary felt so small, she didn't know what to say. Eventually, he stopped looking, and turned back to Mary.

"Did you say something?" He asked, innocently, like he didn't know she'd seen him ogling over this huge busted beauty.

Mary looked away, her glittering eyes fixed on the ocean.

"Just daydreaming." She replied.

\\

That night, Mary found herself in the throes of a deep, fitful series of dreams. It was hard to remember the specifics, but each one feature that huge-titted bimbo on the beach, her bowling-ball sized breasts bouncing and shaking, their massive fake bulk pressing into her partner, as she giggled and sipped champagne. Except when Mary looked closer it wasn't her partner, it was Rob, who was looking deeply lustfully at her giant fake rack, which was so much bigger than anything Mary could offer, and was about to lean in and suck on one of her massive nipples.

Mary awoke with a start, covered in sweat, her chest heaving. Everything felt tight. She was distressed, like she'd been the night before, and there were other feelings throbbing through her, feelings she didn't very much feel like addressing, so she pushed them from her mind. Her already tight vest top was feeling tighter than ever, and her little sleeping shorts were snug around her large butt. Rob slept soundly, snoring gently in the bed, but Mary was never going to get to sleep feeling like this. She slipped out of bed, her body hot and bothered and sweating away, her mind descending deeper into fuzz, and made her way to their huge bathroom and shower. She needed to clear her head.

Mary stepped into the large glass shower cubicle, shucking her clothes from her sweating body, and turned the water on. As it poured over her body, she imagined she was that busty blonde porn star from the beach, showering in praise and cum, adoring the attention and delighting in the adoration coming from everyone watching. And Mary felt herself in that body, running her hands over her huge fake tits, before realizing she was looking at her own, tiny tits, barely E-cups on her slim body. Nowhere near as large as this woman's. But what if they were bigger? What would that look like on her? Mary started to imagine, to think what she'd be like with truly huge breasts, and in her mind's eye she saw herself, and as she looked down, her body started to change.

Her mind was too fuzzy to really get a sense of what was happening to her, her PHD in chemistry unable to translate the reality into something that her brain could understand, but her breasts were…growing. As the water ran over them, they began to inflate, slowing plumping up larger even she looked. It was like the water was running through her skin and ending up in her breasts, which were slowly ballooning larger as she looked. They were stretching out in front of her, getting larger and heavier as she stared, groaning to either side of her, now wider than her slim torso. She loved the sensation of them growing, loved how her brain was telling her this was insane, but also to let this happen; this was everything she'd ever wanted.

Still her breasts grew, getting bigger and wider and larger and heavier as the water poured down from above. Mary started to groan with pleasure as her tits gradually swelled to become bowling balls, huge and round and heavy and incredibly fake-looking. She could feel the silicon inside them, filling her up, sloshing around until the breast became so full there was no room for anything to move. Her breasts engorged further, now so big they were brushing against the glass of the shower. Her nipples immediately grew erect as they touched the cold glass, and Mary almost staggered to the floor as she beheld her new, giant rack. Her tits were so big\! They were so huge, the size of her head, so big that she could barely fit back out of the shower. She turned off the water with some difficulty, her breasts obscuring her view of the taps (and of her feet, incredibly), and she squeezed out through the glass doors, her breasts pushing them open long before the rest of her body got there.

She looked down in amazement, almost unable to process how gigantic her tits were. They bulged out from her, meeting in the middle in an enormous mass of cleavage. They were the biggest breasts she'd ever seen, with the exception of the huge-titted bimbo on the beach. The brain fuzz was so much stronger now, her head full of cotton, thoughts slowly bumping into one another like strangers on a train. Why had she been so jealous of that woman? Her tits were as big as the woman on the beach – possibly a little bigger. As Mary had that thought, her breasts gently ballooned a couple of inches larger, now so big they pushed into her arms if they lay by her side, and Mary knew for sure that her breasts were the biggest. They were absolutely enormous\! She remembered how expensive the experimental surgery had been, how excited Rob had been when she'd had it done, and the look in his eyes when she'd been allowed back home and to remove all the medical tape and bandages. He'd not let her out of his sight for weeks, as they just fucked and fucked and fucked until they were sore from all the excitement.

Mary looked down at her tits, which were now larger than her head, and knew she had nothing to fear – she had the biggest tits in this hotel – hell, maybe the biggest tits in the world, who knew? And Rob knew that, and loved it. Still, Mary thought, as her head grew fuzzier, and her IQ dropped further, like, maybe I should remind him who was really the biggest bitch there is.

Struggling to pull her vest top over even one of her breasts, let alone both, Mary settled with just hanging it over the huge shelf of her gigantic fake boobies, and slipped back into the bedroom, where Rob lay sleeping.

"Hey, big boy." She purred, lifting up the covers and running her hands over his cock, which stirred almost immediately.

"I'm going to tit fuck you and suck your cock at the same time, how about that?"

Rob's eyes gently lifted open, his impressive cock standing to attention, and Mary put him between her giant tits, taking the head of his cock in her mouth, smothering his large dick with her enormous breasts, and began to tit-fuck him into oblivion.

"I'm dreaming." Rob smiled, as pleasure took him into oblivion.

But he wasn't. Not by a long shot. And things had a long way to go yet.

Mary didn't dream anymore that night.

She slept soundly until she awoke to the feeling of labored breathing and pain on her chest. She frowned, and rolled over to the side, her gigantic breasts thumping into the bed with a loud smack. They almost poured off the edge of the bed, threatening to drag her to the floor, but luckily Mary woke up, pulling herself from the edge back towards the center of the bed. She had to be more careful – ever since she got these gigantic implants all those years ago, she knew that she was so top-heavy she could tumble out at the slightest provocation. Being this busty had its drawbacks, though they paled in comparison to the benefits.

She shuffled back towards the center of the bed, the tee she'd worn to sleep in barely covering her belly button. It was one of Rob's old sports ones, and was big on him. It was huge on her, except for the fact that her breasts erupted like the massive balloons they were, taking up so much space that even this massive tee managed to be quite tight on her. She lay back on the pillow, her tits erupting towards the ceiling. It was hard to lie on her back, she had to keep reminding herself of this. There was so much silicone in her breasts, the weight made it hard to breathe. She leaned onto her side, her breasts taking up all the space between her and Rob, her huge nipples brushing against him, her massive, wobbling mounds so huge and expansive.

"Morning babe." Came the sleepy response from Rob, who rolled over to get a face full of boob. "You think I'd be used to these things by now." He grinned, pulling away to look at Mary's face, which looked so small compared to the twin globes that rose and fell just below it. "My big booby busty beauty."

Something about the alliteration of all those "b" words sent joy through Mary's increasingly simple mind, and she giggled. "I'm your big booby busty beauty\!" She parroted, giggling and getting on top of Rob, her huge tits almost obscuring his face as she looked down. She arched her back, making her breasts look even more enormous than they were, and Rob's cock pulsed against her cunt, just like she knew it would. That always got him going, no matter what time of day it was.

"I'm going to fuck you so hard." He grunted, tearing off his clothes. Mary struggled to remove her tee, her gigantic tits proving quite the challenging obstacles to overcome. Eventually, after much giggling and getting stuck, her phenomenal tits were loosed, and she began to ride Rob's cock, her massive fat boobies slapping against her chest, threatening to pull her down to the bed, they were so huge and heavy. Before long, they were both coming incredibly hard, lust filling both their brains.

\\

"So, where do you want to go today?" Rob asked, pulling on a skin-tight tee. Mary played with her long, blonde hair, and looked at him, confusion in her fuzzy mind. Rob had always been slim and svelte, but now he was so tall and buff it rattled her brain. She was going to go to the shower to clean the cum out of her, but instead the marvelled at how muscular Rob's arms were. Her brain fuzzed and fizzed, trying to process what was going on. But it was running on a lower capacity than ever, and before long, Mary knew Rob had always looked like that. Maybe at one point he hadn't been muscular, but not when Mary knew him. He'd always been her tall, buff man. She wouldn't have him any other way.

She moved up to him, as close as she could get with such enormous fake tits taking up the real estate directly in front of her. She pushed her titties into him, and they bulged upwards in an insane mass of cleavage. Rob looked down with undisguised lust in his eyes.

"Can we go see the horsies?" Mary asked, her hands running up Rob's bulging arms, which looked incredible in his slim fit tee. Her husband was so buff, and Mary loved it.

"Uh, sure. I'm not sure they have horses here, but there's a farm nearby we can check out."

"Thank you." Mary purred, squeezing Rob's arms, and swiftly removing his large dick and sliding it into her mouth.

\\

Once they were cleaned up and had found some clothes for Mary to fit into – this being no mean feat, they ended up getting one of Rob's largest tees, and tying it under Mary's gigantic breasts, having it double up a kind of t-shirt / bra combo – they wobbled their way to the farm. Mary's tits were so huge that even in this very busty place, she turned heads. Everyone stared at her massive rack, and it made Rob even more horny for her. He pulled her close, loving the huge, fake tits that pressed into his side. No matter where she was, there was the chance her breasts could get in the way – and Rob loved that. He loved how massive his wife was, and how she was all his. Mary, for her part, loved feeling she was the center of her husband's world, that he had eyes only for her. She had dim memories of feeling inadequate, in some other life, many moons ago, but with her gigantic fake tits being the biggest around, there was no way he'd ever look at anyone else. And that thought made her very happy.

When they made it to the farm, it turned out there weren't any horses. Rob doubted someone with breasts as large as Mary's would have had a very good time riding them anyway – her chest really looked like it would have been an impediment at this stage.

Instead, it was a milk farm, with a bunch of cows lined up in stalls, providing fresh milk for the island. It wasn't what either of them were expecting, but it was fun enough for a little trip, and they walked around the place, examining the cows, giving them a pet, looking at the machinery they used.

And then Mary saw the milking device, the large metal suckers used for clamping on the cow's udders and expressing the milk from them. And when she saw that, everything changed. Her mind, so full of fuzz and lust and desire to be huge, saw the milking device, and knew that it was what she wanted. Synapses fired, neural connections were made, and she looked at Rob with eyes of fire. The fuzz was still there, clouding her thoughts and making her simple, but through her simplicity came a razor sharp focus that told her what she wanted and needed right now.

"I don't want anyone to be able to use this if I can't." She said, angrily, holding the pump up to one of her massive, fake, bloated tits. "Can you imagine, some cow being milked, and not me. I'm the biggest cow there is\!"

There was no one around, and Rob raised an eyebrow.

"Is that what you want? To be a huge a cow who gets milked?" He stepped closer, his muscles bulging in his tight tee. He was so tall and powerful.

"I want to be your cow, and to be milked. Because my big, fat titties are the hugest udders in the world, and like, the only way to stop me exploding is to get out all the milk I produce. Because you're my bull and you've fucked me and now I'm going to pop."

Rob had no idea where this was coming from, but he couldn't deny he liked it. He envisioned Mary with gigantic, milky udders, her breasts impossibly large, bulging out in all directions, so huge she could barely move, and his cock grew rock hard. Mary, at the same time, was imagining herself with similarly giant, milky breasts, and the thought sent bolts of arousal through her brain.

"How big would you want me?" She smiled, moving towards him, pump in one hand. Her massive, fake tits, stuffed into the shirt tied at the waist, even bigger than her head, wobbled a little, so huge and swollen.

"You couldn't handle how big I want you."

"Pfft. You have no idea what I can and can't handle. I've managed tits like these." Mary scoffed, hefted her giant tits with both hands, something that was difficult, they were so large and heavy. When she let go they almost pulled her forwards into Rob's arms.

He laughed at her top-heavy antics.

"I want you to have the biggest breasts in the world. So big you can't move. And I'm just going to fuck you with my big bull cock because you'll be my cow, and your udders will make so much milk."

"Mmmm, tell me more, my big bull." Mary grinned, reaching out and grabbing Rob's impressive cock. "I like the sound of this."

And as they toyed with each other, egging each other's fantasies on, Mary felt the fuzz in her brain, more powerful than ever, and the tension in her body, and she began to balloon larger once more. This was the first time she'd been so clearly aware of it, but her brain was so fuzzy it was hard to put words to it. It was like this was what was always supposed to happen. All was right in the world.

"I think it's happening, babe. I'm getting bigger and milkier for you."

Rob's eyes widened, but only a little. Part of him knew that this was going to happen, too. But that didn't mean he wasn't going to enjoy it. He sat down with Mary, their legs entwined, as her boobs began to grow. It was hard to tell, initially, because her tits were already so big, any expansion was less obvious than it had been when she'd been but a meagre B-cup. But with her massive, cannon ball-sized breasts strapped to her chest, it was more difficult to observe the expansion. But Rob placed his hands on her colossal tits, and then knew they were growing. He could feel them moving outwards, with each breath Mary took, and could see the t-shirt tightening around their preposterous mounds, as they grew bigger and bigger.

They were getting heavier, too. Mary could feel the contents of her tits being filled up, just like when she'd had all that silicone installed, except this time it was milk that was being pumped inside her. Her breasts were engorging, spreading outwards in all directions, but mostly they felt like they were thickening, getting more dense as well as getting so much bigger. They were already so heavy, but now it felt like she was carrying a wheelbarrow of boob in front of her as her tits expanded. They were getting so huge and milky, droplets were now starting to drip out the end of her tits, soaking into her t-shirt, her massive, watermelon breasts so immensely huge and full it took all her strength to hold them up. She sat on the floor opposite Rob and mooed gently, her breasts spreading outwards all the while.

"Moooohhh it feels so good babe." She groaned, patting the tense, thick sides of her massive udders, feeling the solid, stuffed contents barely moving as she touched it. She was so full, it felt like she was going to explode.

"How big shall I get?" She whispered, as her breasts grew larger. They were now approaching twice the size of her head, and were so big the massive tee was starting to come undone where she'd tied it under her gigantic bust. It honestly looked like she taken two beach balls and shoved them under her shirt, but both of them knew these babies were real, and were the hugest, sexiest tits there were.

"I feel like I'm going to burst." Mary moaned, her breasts stretching larger. They were now pressing into Rob, even though he was sitting quite a way from her. Mary's chest was now so enormous, it was hard to be anywhere near her and not be touching her tits. Rob loved it. He loved how huge his wife was.

"We should get you home, before you leak milk all over the place." Rob grinned, hauling Mary to her feet with considerable difficulty, eventually getting her to totter upright. She almost overbalanced, her massive milkers almost dragging her back down to the ground. They now took up most of her top half, and her massive shirt was barely holding them in place, she was so insanely busty.

"I'm going to explode." She whispered in Rob's ear, only intensifying his boner as he imagined how huge his wife's tits were going to get.

"You and me both." He grinned, guiding his pair of breasts on legs towards the hotel, where she tottered with shaking legs towards their room.

\\

The sex was incredible. Rob laid Mary down, after he managed to squeeze her into the elevator and get her into the room, her breasts now so huge and full she could barely move. The bed almost smashed to pieces as she fell onto it, her t-shirt now a mockery of its former self, it was so stretched and battered.

When Rob got her down onto the bed, he pulled it over her stupidly large breasts, and almost came there and then when he looked at them. They now took up almost all of Mary's torso, and were so towering and stuffed with milk they resembled actual beach balls. They were primed and ready to explode, so Rob went to town on them, milking and fucking them as Mary cried with pleasure. Soon everything was a creamy, milky mess. Cleaning this room was going to be nightmare; neither of them envied the staff who were going to have to sort that out.

And, after insanely good sex, Mary's breasts having deflated a small amount from the milking, they both fell asleep.

And they both dreamed. And these dreams had almost identical content, so much so that the two people creating them appeared to be in perfect mental synchronization. And this had the effect that their dreams combined, their twin desires flooding into one another, strengthening the other, so that when Mary dreamed of having enormous milky breasts and being a big huge cow with huge udders, and when Rob dreamed of being a massive dominant bull with an enormous dick for fucking his cow, they both awoke in the night feeling too horny to speak. It was like their minds had been wirelessly connected, and they knew what each other wanted.

"Get on your front." Rob ordered, his muscles rippling, his cock bulging out in his struggling underwear. He was growing an absolute monster down there, a huge cock to put any bull to shame. His balls were swelling to the size of tennis balls, and the virility inside him was pulsing through his every nerve. He breathed through his nostrils, so deeply turned on if he didn't come very soon he was going to destroy this whole room.

Luckily, what he wanted was his enormous-breasted cow wife in front of him – that was what he wanted more than anything in the world, so when she got on all fours, her gigantic udders swinging down, almost pressing into the bed, which was groaning under her huge weight, his cock burst from his underwear, spreading outwards, almost a foot long, dripping with pre-cum.

Rob moved to his wife's neck, and took a deep, long sniff, tasting her scent, loving her deep and profound arousal as his huge, wobbling cow, ready to take his seed. She had the most enormous udders he'd ever seen, but he knew that she was going to get bigger, and that was what he wanted. She had so much milk to express.

"Fuck me." She whispered, her voice quivering with anticipation. "Fuck me with your giant bull cock. Mooooo."

The last sound was almost whispered, but it was that that sent Rob into overdrive, his giant cock throbbing and growing, so massive and thick he wasn't sure it was going to fit inside his giant wife.

Luckily she was so turned on it slid into her aching, wet cunt, and before long Rob was pounding his gigantic-breasted wife, who mooed with pleasure, gripping the bed as best she could, trying to stay on all fours while her husband's massive cock pumped inside her.

It was like he was filling her up with milk, because every stroke of his colossal dick caused her already gargantuan breasts to swell larger, to fill up with more milk. She was becoming his perfect cow, and as he fucked her with his enormous dick, her breasts ballooned larger and larger. They were already so huge and heavy, it was almost scary for Mary that they were getting bigger. Yet it was also exactly what she wanted, and before long they got so huge they began to bulge into the bed, which took the weight off Mary. Now that she no longer had to support her breasts, because they were resting on the ground like twin bean bags, she ground her cunt against Rob's thick cock, feeling every inch of it inside her, loving the immense sensations of pleasure as her husband fucked her to within an inch of her life, her breasts ballooning bigger all the time.

Before long, she was being lifted up in the air, her tits were so huge. They were now around 50% of her body, her massive fun bags so colossal they were spreading out across the whole bed. The bed was straining under their weight, and both Rob and Mary knew it was going to break before too long. Sure enough, after Mary swelled another few inches, her breasts now wider than she was, and so huge and heavy, the bed legs shattered, and both of them tumbled to the floor.

Luckily Rob was hugely powerful and muscular by this point, and so held her with both hands, essentially spit-roasting her body, with him holding one half, and her breasts, now the size of large medicine balls, holding up her other half.

They were both going to come soon, it was impossible to avoid that fact. Mary was so full of milk she weighed about three times as much as before, and Rob was such a huge, powerful bull he was going to destroy something if he didn't come soon.

They were both grunting and shouting and moaning and groaning, and Mary was rubbing the sides of her globe-sized breasts, trying to get them to express, concerned that if they got much bigger she was literally going to burst. They were so full, and while at the moment they were happy to expand, she felt on some level that there were limits. And while she didn't know what those were, she felt sure she was close to them.

"Oh fuck, I'm going to…AAAAAAAHHHHH\!\!" Rob cried, with the intense power of an animal, and began to blast hot, thick cum into Mary's waiting cunt. At the same time, her breasts, which were now so large they had lifted her a meter into the sky, began to fire huge bolts of milk from her huge, erect nipples.

Cum and milk was firing everywhere, the room becoming pasted with hot, thick, white substances, and both Mary and Rob were experiencing orgasms the like of which they'd never known. Their animal bodies were on fire, sensations coursing through their veins like nothing on this world.

After a long, protracted climax, finally they were both done. Mary fell immediately asleep, as did Rob, still inside her. Neither of them dreamed.

\\

The next morning, it was time to go home. Both of them knew that their lives would never be the same again, and that this trip had awoken many things inside both of them.

Mary's breasts, when she awoke, were still the biggest pair of tits in the world, far larger than when she'd had implants, but were now natural again, and positively stuffed with milk. But with judicious milking (and some more fucking from Rob), she reduced them to the size where she could just about manage to walk. They barely fit through doorways, but if she moved one boob at a time, she could just about manage it. They couldn't both get in the elevator, because Mary almost broke the weight limit on her own, but somehow they made it to the reception, where the busty woman they'd met upon arrival – that felt so long ago\! – asked if they'd enjoyed their stay.

Rob and Mary looked at each other – both so changed in the short few days they'd stayed in this wonderful, magical place – and smiled widely.

"We certainly did." They smiled, responding together, in perfect synchronicity.

"I'm so glad to hear it. You're both certainly looking…more." The receptionist smiled, noting with a nod of her head Mary's breasts, which were covered by the bikini she'd worn on the second day. They'd had to add a couple of feet to the length so that they could tie it around her insane breasts, but she was leaking so much milk, plus no other clothes would even remotely fit her preposterous bust, that this was their best bet. Plus it was a holiday\! You had to wear your swimming gear on holiday.

Both of them waddled to the door, Mary because her tits were so huge that movement was, whilst not impossible, a huge challenge, and Rob because his cock had gotten so large that it made walking genuinely difficult for him too.

They hailed a taxi, and Mary managed to just about squeeze her tits inside. They were so large, they burgeoned up to the seat in front, with no room between her and the seat. All she could see was cleavage. She tried not to leak milk into the cab, but it was hard to resist. She was filling all the time, and the hornier she got – and her figure made her feel constantly horny – the quicker she filled. It was quite a conundrum, but a very sexy one.

They made it to the airport, and after some comical experiences with airport security, with a lot of stares (Mary was big, even for some of the patrons at this hotel) and a lot of squeezing through tight security equipment, they made it on the plane. It was time to go home.

"Wow, what a trip." Mary smiled, the fuzziness in her head greater than ever. Her giant tits were all she cared about, and having Rob's entire focus on her monstrous rack the whole time gave her a thrill the likes of which she'd never known.

"You said it babe", Rob smiled, wrapping his arm around her as they sat on the plane, ready to take off. They'd had to move to a front row, because Mary's tits were simply too big to fit anywhere else. The flight attendants had raised an eyebrow, but the flight was pretty quiet, so no one really minded.

"So, like, when we get home, then what?" Mary asked, looking at Rob hopefully, her stupendous breasts rising up and down with each breath. She was so huge and beautiful, Rob scarcely knew what to do with himself.

"Well…as my cow, you're going to have to make me lots of milk. And I think you've got quite a bit of growing to do." He smiled, poking one of her insanely huge breasts, causing a little squirt of milk to pop out of the end of one of her monstrous teats.

"Hey, quit it\!" Mary laughed, her tits shaking so hard she almost bounced into the person next to her.

"But yes, I think that can, like, be arranged." She smiled, taking some gum and putting it in her mouth, as the plane flew off into the sky.

She knew what she had to do. They were done with vacation now, it was time to get back to the real world, time to get serious.

Time to get truly huge.
