Grace was amazing. No two ways about it. Mike was obsessed with her, and sometimes couldn’t believe he’d ended up with someone so gorgeous. Petite, devastatingly pretty, Grace was an exchange student from Korea who Mike had someone how ended up calling his girlfriend.

Maybe it was because she didn’t know anyone in Sydney, let alone Australia, maybe he just turned on the charm in the just right way, but they were together, they were an item, and Mike regularly pinched himself to make sure he wasn’t dreaming.

Then Mike started to realise that, as beautiful and perfect as Grace was, she perhaps wasn’t the nicest person in the world. She would ignore him if she was busy, and not always treat him as kindly as he would have liked. This was fine – she was at least honest with him, and if he was honest with himself she was way out of his league.

But then her exams came.

Grace was in the country to study, and she took her work very seriously. Mike got this – he’d spent a lot of time studying, and knew how important it was to get good grades. But Grace would lock herself in her room, in this big old house she’d rented with some older students called Jack and Christina, and Mike would never get to see her. Often she wouldn’t even answer her phone. Mike knew she was busy, he knew he had to respect her boundaries. But after weeks of barely seeing her, he was starting to get frustrated. And his balls were blue as hell.

Mike pushed those feelings down, knowing they were selfish and that he should be focusing on Grace’s needs, but they bubbled up at the most inopportune moments. He was climbing the walls. Eventually, after weeks of frustration, he decided to get Grace a gift. He wouldn’t ask to see her, just deliver her the items, and hope that that would get him an audience with her. Eventually.

Feeling like his nuts were going explode, Mike went to a hippy district in Western Sydney and went to a gift shop of that kind that he knew Grace loved. She was very keen on tarot readings and fake magic and all that kind of nonsense. Mike found it endearing, even though he didn’t believe any of it for a moment.

Stepping through the door of the shop, through a waterfall of beads, he smelled a peculiar, sweet incense and noticed the smiling young woman behind the counter. Mike felt his pants tighten. It had been so long. Her large, round, full breasts poked out of the top of her tight, white button blouse, threatening to burst it open. He tried not to look, but her tits were so full and luscious that his eyes could scarcely keep away.

“Can I help you?” She asked in a soft voice, ignoring his obvious arousal.

“Ah yeah, I’m looking for a gift for my girlfriend. She’s real busty-uh busy studying and I want to help her relax, forget her troubles. Know what I mean?”

The woman smiled, her perfect white teeth glinting as the afternoon sun poured through the dusty windows, motes swimming in the heavy air. It was a hot day.

“You want to make a big impression, don’t you?” As she said this, she arched her back, and her breasts seemed to swell forwards in her shirt, almost bursting the top button open. Her cleavage was so luscious and full Mike thought he was going to come there and then. It was like her breasts were expanding in front of his very eyes, like they were going to explode. Mike desperately kept his eyes on her face.

“Yeah, sure. Real, uh, big.”

The woman looked at him, her blue eyes twinkling, and produced a teddy bear, bunch of flowers and chocolates. They were all fairly non-descript items, very traditional “romantic” gifts, which made them seem very at odds with the kooky, alternative vibe of the shop. But Mike was barely thinking about it. He was trying not to look at the woman’s huge tits, and how they seemed to be growing, even though that was impossible. She bit her lower lip, looking up at him, and he could have sworn he saw a damp patches starting to form at the tips of her perfect, huge breasts, around the rock-hard nipples.

Mike grabbed his card, flustered, and paid for the items, all the while trying not to look at the deep, luscious cleavage that emanated from the bulging bust in front of him. He shoved everything into a bag, took one last look at the woman, who was smiling widely, and looked like she was going to burst apart some buttons, and hurried out of the shop.

As he left he could have sworn he heard a gasp and ping of plastic, and thread snapping. His boner only intensified.

Grace looked at the gifts in her room. They were sweet enough, if totally corny. But she had work to do. She sniffed the flowers, her body tingling with pleasure as the scent coursed through her, ate one chocolate – pretty tasty – and put the bear on her bed. It was a sweet gesture for Mike, but she had work to do. She’d speak to him later.

She adjusted her strappy top, her non-existent breasts barely nubs against the fabric, and got back to her books. Biochemistry. Not easy, not fun, but lucrative. It was going to all be worth it; she was going to get the highest grades in her entire year, she just knew it. Then the best job, then the best house…the list went on. And it all started here.

Leaving the box of chocolates on her desk, she settled in her comfortable office chair, and got to work.

What felt like hours later, she emerged from her focus, and noticed the room around her. The box of chocolates was half empty. Wow, she’d really put them away. Her body felt heavy and sluggish and full. She adjusted her top, her breasts round and full, jutting out an inch or so. Hold on a minute. They were swollen. Much bigger than she was used to. What was going on?

Grace observed the curve of her tits in the mirror, admiring how they blobbed out a little bit, giving her slim body some curve. She liked it. Must be her time of the month. She got up, going into the living room, where she placed the chocolates and flowers, so everyone could enjoy them.

Housemates Jack and Christina were snuggled on the couch, watching a show on Netflix.

“Hey Grace, how’s it going?” Jack asked, brushing back his blonde hair. He was handsome, and him and Christina were great together. She was voluptuous and curvy, and he was tall and muscular. They were cute. Not that Grace had time to think about that.

She popped another choc, feeling her swollen breasts and moved to the kitchen to get a snack.

“Good thanks. Getting there, y’know?” She opened the kitchen and saw a long, thick, juicy cucumber. It made her think of a thick, veiny cock, and visions of Mike and Jack’s dicks flooded into her mind for a just a moment. She slammed the door, grabbed a glass of water, and hurriedly drank it down. Just study pressures. That was all. Feeling her breasts, which were sensitive and seemed even larger, she passed the chocolates to Jack and Christina, who took a couple gratefully.

“Check out the flowers Mike gave me.” Grace smiled, sharing the gift with the group, placing it on the dining table. “Sweet, but it’s not gonna get him any of this.” She pointed to her bulging tits, shaking them a little. Funny, she didn’t used to be able to do that. They were bigger.

“You’re such a bitch.” Grinned Christina, chewing on a chocolate, her eyes on the TV.

Grace laughed, going back into her room.

She sat down, her tits uncomfortably full and engorged, and got back to work. Before long she was tired, and she crawled into bed. Images of thick, juicy cocks swam in her mind, and she fell asleep.

Once she was asleep, the bed she was cuddling began to whisper.

“Grow. Grow. Swell, fuck and grow…” On and on it went, as Grace slept through the night.

Mike saw her a few days later, when she eventually invited him over, and was shocked to see her breasts were absolutely enormous. By any normal standards they were pretty average, but on her petite Korean frame they were large, round and perky, and stuffed her t-shirt tight, round and pert as oranges.

“Hey babe, how are you?” He stammered, even more attracted to his beautiful girlfriend than usual.

“Fine.” She muttered, turning around and showing her gorgeous ass, packed into lounge pants, as she padded across the floor. “Work’s a bitch, but I’m getting there.”

She absent-mindedly adjusted her boobs, which looked shockingly big in her top.

“New bra?” Mike ventured, noting how supported her fat tits were. They looked like D-cups, or larger, far too big for Grace’s slender frame.

“Mmm.” Grace replied, moving into her room and sitting down at her computer, not paying Mike much attention.

Mike closed the door behind him, noticing a large cucumber on the bed.

“Healthy snacks, am I right?” He offered, awkwardly but not without charm. Grace turned around irritably, and when her eyes fell on the cucumber, her cheeks flushed, and she turned away, her eyes sparkling.

Mike didn’t know what to say, so he sat on the bed awkwardly for a while, smelling the strange smell in the house. It reminded him of the shop. Sweet. Thinking of that moment gave him an awkwardly quick and large boner, that he tried to hide with the teddy bear.

“How are Jack and Christina?”

At this, Grace spun around, looking at him with the full force of her beautiful, penetrative stare.

“Weird, y’know. For the past few days they’ve been all over each other, and fucking like crazy.”

Mike gasped. Grace rarely talked candidly about sex like this. She was a prude.

“And like, I wouldn’t mind, but they’re really freakin’ loud, and they do it, like, all evening. I’m trying to get work done, you know! I think it’s Christina’s new boobs.”

Mike’s mouth started to go dry.

“Yeah?”

“Yeah, she’s got a new bra or implants or whatever – either way her tits are fucking massive, like twice the size they used to be – and it’s driving Jack wild. Not hard to see why. He walks around with a boner like all the time, and his dick looks freakin’ huge.”

Mike didn’t know what to say. Grace never talked like this. He looked at her, and saw her rubbing her slim, toned thighs together. She bit her lower lip, and tried to focus on her work. She was clearly deeply horny.

“Must be hard to focus with all these…tight clothes about.”

As he said this, Mike was looking at Grace’s t-shirt, which looked like it was being pulled down by her hands, but that was impossible – her hands were on keyboard and mouse. But all the same, her top was somehow getting tighter…stretching and pulling like it was being dragged from below. But it wasn’t. Instead – and Mike couldn’t believe this – it seemed her tits were getting…bigger.

Even as he looked, as she bit her lip and writhed a little in her seat, her already much larger breasts were swelling in size, gently but insistently spreading outwards. He could see her excess breastflesh gently spilling over the edge of the bra cups, pushing them forwards as more and more boob jostled for space. This made no sense. What was happening?

She turned around and looked at Mike, her gaze immediately dropping to his crotch. The bear was in the way, but she licked her lips, looking at where his cock was hiding, and her breasts swelled again. They were the size of small melons now, and Mike could hear her bra straining to deal with the increased load. Her t-shirt was gloriously tight. She looked incredible.

Grace took one last, longing look at Mike’s crotch, then span back to her computer, her eyes focusing once more.

“You have to go.” Was all she said. Mike left more confused than ever.

He walked down the street as the sun sank low over the horizon, hands in his pockets. His balls were only getting bluer. He thought of Grace’s huge new tits, and what was happening to Jack and Christina, and wondered where it was all going to end.
