Maisie had always been a bit overweight. Not fat, per se, but chubby. Her thighs were a bit thicker than all the others girls, her arms a bit chunky, she had a bit of belly. She always liked to wear tight clothes, but they didn’t look quite right on her. If she’d kept to the looser stuff, she’d have been fine. But she didn’t, and that pissed off her boyfriend Josh.

When they’d first gotten together, Maisie had been pretty slim. She’d always struggled a bit with her weight, but Josh didn’t know that, so they’d entered into a relationship with slightly different ideas of where it was going. The more comfortable Maisie got, the more her belly grew, and the more her clothes became that little bit too tight.

On the plus side, her boobs were quite a lot bigger than when they’d first met – something Josh was very much in favour of – but apart from that, this didn’t seem like a fair deal. Josh kept himself in pretty good shape, but Maisie really seemed to be letting herself go, and he didn’t think it was fair.

At the same time, this was a tough thing to bring up – how do you tell your girlfriend you wished she was a bit thinner? Sure, a lot of people think it, but to actually say it? That was a whole other thing. So Josh, being a slightly awkward type, decided to find a way around it.

He tried all sorts of things; subtly bringing up that he’d lost weight, hiding the more sugary foods, encouraging Maisie to go for a run, but nothing worked; she was just slowly getting fatter and fatter – still nowhere near being properly fat, but fatter nonetheless. And Maisie wasn’t that tall – around 5’4 – and when she wore her hair up in pigtails, it always reminded Josh that she did look like a bit of a piggy.

So Josh took drastic action. He’d found this experimental supplement talked about in dieting forums online that dealt with weight redistribution. The idea was, the pink pills took the fat your body was processing, and somehow channelled it straight to the boobs, bypassing the stomach and hips. You could also get a version that sent it butt-wards, though Maisie certainly didn’t need that; her booty was plenty ample.

And so Josh bought up a little bit of this supplement, and started sneaking it to Maisie. And it began to work! Her clothes slowly grew slightly less tight around the stomach, and considerably tighter in the chest. Day by day, her boobs gradually grew bigger, as the fat was redirected and poured into each breast, which slowly became larger, heavier and more swollen.

Each night as they went to sleep, Josh lay on his side with his back to Maisie and she leant in, pressing herself against him. At first, it was mainly her stomach that he could feel, but over time, that started to reduce, and the two growing mounds on her chest were the things that made impact. And Josh started to find himself getting very, very aroused.

Maisie seemed to only have passing awareness that this was happening. She would occasionally complain of a tight bra, but to Josh it seemed crazy that she hadn’t noticed – her boobs were way bigger than before! They’d been a small D-cup before, but now they were well on their way to a large E, and poked out in front of her shrinking form like two large softballs. Josh kind of loved the fact that Maisie didn’t know how big she was getting. He liked her pulling at her bra straps absent-mindedly, or having to move her book further away from her so her growing tits didn’t obstruct what he was reading.

So Josh upped the dose.

Only a little bit at first, but more and more, as Josh got carried away with remoulding his girlfriend into exactly what he wanted.

But the problem was, the more Josh gave her, the more Maisie ate.

The supplement was supposed to have no effect on appetite, but Maisie’s was more voracious than ever. If anything, she seemed hungrier and hungrier the larger she grew, and once Josh upped the dosage, that was starting to become quite large indeed.

Then, one day Josh got home from work, and saw Maisie sitting on the sofa, surrounded by junk food. There were tubs of ice cream, packets of chips, mounds of dips, chocolate bars galore.

She looked up at him as he came in, chocolate smeared around her face.

“I’m so hungry”, she moaned, reaching her arms apart to hug him. Josh looked down at the beautiful, swollen pair of F-cup balloons that were erupting out of her incredibly tight t-shirt, the words “rock star” stretched tortuously across the taut fabric by the massive tits swelling beneath, and immediately grew hard.

He sat down on the couch next to Masie, and felt her beautifully large, pert breasts sigh into him as they hugged. He loved how big they were getting, and loved watching Maisie squeeze her growing form into the same clothes, day in, day out. Her shirts were all so tight now; her growing boobs were just too large to fit. The best bit was when the shirts rode up to cover her swelling bust, and her stomach poked out the bottom – she was getting so slim! The combination of big tits and thin waist was driving Josh crazy.

Maisie pulled out another chocolate bar, and ripped open the wrapper, stuffing it into her mouth. She’d taken to wearing sweat pants as her butt hadn’t lost any of its size, and indeed was getting pretty large. The supplements certainly hadn’t stopped any of the fat going down there; if anything, it looked even bigger. And the more she ate, the larger it got.

Maisie kept trying to tell Josh something, but every time she got started, it was like she remembered there was a whole array of food around, and she got distracted and started eating again. As she crammed more chips and then ice cream into her mouth, Josh noticed it going to her boobs.

“I’ve been eating all day”, she moaned, shoving more ice cream in as quickly as she could. “I don’t know why, but I’m crazy hungry. Do you think I’m putting on weight?”

She lifted her t-shirt to pat her stomach, but realised she couldn’t actually see it beneath her heaving tits; they were so big and firm now – like ripe melons – and packed her stuffed t-shirt to the max. She looked down in confusion for a second at her huge tits, prodded them once with a slender finger, and then went back to her food. Josh started to worry she’d taken too much of these supplements; he hadn’t really looked into the list of side effects very carefully.

But Maisie didn’t notice the look of concern in his eyes, as she carried on eating, grabbing a couple of chicken wings and ripping the flesh off them with her teeth, smearing sauce all around her mouth.

Beneath her dripping chin, her boobs inched forwards, her struggling shirt straining against their expanding mass. Josh watched in amazement as her breasts literally grew in front of his eyes. He’d noticed them get bigger day on day, when he saw things like Maisie squeezing her noticeably larger bust into too-small bra, but he’d never seen them actually expand in front of him. It made him spectacularly aroused.

There was a “ping” as the current bra Maisie was wearing (she’s upgraded to a G-cup a while back) broke off as her breasts surged forwards. Josh watched, practically drooling, as Maisie’s twin balloons inflated under her shirt, bringing it forward more and more, until her breasts had slowly expanded further forwards than her head. Josh loved watching them grow, filling up her top more and more as she sat cross-legged on the couch, blowing up larger and larger, Maisie apparently not noticing.

Her tits were gigantic now. Big, round, full orbs packed into her t-shirt, which was fit to burst. Now bra-less, they wobbled as she munched, and looked like big fat bags of gas, they rode so high on her. Josh longed to reach out and grab them, feel their tight, bulging mass, but he didn’t want to interrupt the almost trance-like state Maisie was in.

She was alone in her own special world, shoving food in by the handful, growing larger and larger. Josh loved the sound of the couch groaning as Maisie’s mass increased with each mouthful of food she swallowed. Her breasts were looking absolutely magnificent, buckling the t-shirt every time she breathed in, which caused them to swell outwards with the intake of breath. They were the biggest boobs Josh had ever seen. He wanted them.

“Maisie”, he said, not sure where to begin.

Slowly, she turned her head, and let out a large belch, which sent her fat boobs jiggling.

“Mmm?” She asked, grabbing a massive bottle of coke, opening it with a fizz and shoving the top in her mouth, glugging it down like a baby with a large bottle.

Josh watched her take in what looked like a quart of coke, just guzzling and sucking and spilling out the side of her greedy mouth. And it looked like the coke was filling up her boobs.

As Josh looked on, Maisie’s throat undulating madly with the mass of liquid that was pouring in, her boobs blew up and up, inching outwards in pumping bursts as each massive swallow took place. It was a magnificent sight to see, as if someone was pumping a large bellows, each stamp of it inflating air into an already over-inflated pair of balloons.

The stuffed seams either side of Maisie’s colossal breasts started to burst open, and Josh could see hints of the enormous boobs that lay beneath. He loved the thought of how huge they were in the flesh, and longed to tear open Maisie’s clothes and stick his dick between them.

Eventually, Maisie finished with the coke, and put the bottle back on the floor, her breasts squeezing madly into her legs as she leant down. She sat upright on the sofa, and burped, hugely. Josh found it strangely arousing, this complete lack of decorum. Maisie blinked, arched her back with a big yawn, and burst her shirt open.

There was a huge tear, and her massive tits surged through the incredibly tight fabric, a glorious cavern of cleavage revealed as the top of the t-shirt tore completely down to the midriff.

She looked down at her preposterously huge, no longer measurable tits, and giggled, shaking her chest and watching them wobble madly, too massive to be real.

But they were real.

Josh slid closer to Maisie on the couch, until he was inches away from the massive width of her left breast, which shuddered and wobbled with each breath, clearly still groaning larger and bigger as the immense amount of calories she’d consumed took effect. The bottom part of her shirt still just about contained her immense boobs, but the tear down the middle was making it look like a highly insubstantial bikini, and it wasn’t going to last long.

Josh looked Maisie in the eyes, and kissed her on the mouth, poking his hard dick into her side.

She smiled, and reached for the whipped cream. Josh guessed what was coming, and unzipped his flies, hauling out his large dick. Straight away, Maisie sprayed cream all over it, and started licking and gobbling it off. She struggled to lean over fully to reach his cock, as her tits were simply put, too enormous.

She leant down to reach his dick, but they squished up beneath her, and bulged madly into space-hopper sized mounds they squeezed gorgeously into one another.

Josh watched Maisie’s tits expand and wobble while she sucked on his cock, and knew his arousal couldn’t last much longer. He was desperate to put his cock between Maisie’s enormous jugs, but the way she sucked his cock was incredible; she’d never put such vigour into it.

At the last minute, Josh pushed Maisie off him, leaning her back on the couch, her gigantic balloons sticking up into the air. Ripping the rest of her pathetic excuse for a t-shirt off her swollen jugs, he shoved his rock hard dick between her tits, and thrust back and forth. It felt so tight and incredible as her enormous tits grew bigger still, pushing him up and away from her, clamping harder and harder around his throbbing cock.

And then Josh came, hard and fast, pumping big thick spurts of cum into Maisie’s face. She turned her mouth with each one, not to avoid the jizz, but to catch it at eat it, revelling in it and enjoying eating as much as possible. And still her boobs wobbled and swelled.

Josh lay on top of her gigantic melons, as they continued to rise and fall with her slightly laboured breath, and looked down at his balloon-breasted girlfriend.

Maisie smiled, licked her lips, and reached for a chicken wing.

She was going to get a whole lot bigger yet.
