Subway

Valerie stood in the crowded subway carriage, cursing everything and everyone.

Her nose was embedded in some fat businessman’s armpit, and it smelt like infidelity and broken dreams. Even this pungent bastard couldn’t ruin her mood, though. She was on her way to her third date with Simon, and she felt a tightness in her chest that she couldn’t quite explain; he was handsome and caring and intelligent, and she felt good about it.She’d come straight from work, so was wearing a black pencil skirt and white blouse, which looked great on her tall, slender figure, but just in case she’d put on a special bra to accentuate her small breasts. She’d bought it just the other day, and hadn’t tried it before. The lady in the shop said it would make her breasts massive. “Look massive, don’t you mean?”, corrected Valerie. But the lady had already gone on to serve another customer. Valerie thought nothing more of it, but her breasts did indeed look a little bigger than usual. Not much, and certainly not massive, but the slightly looser blouse she’d worn specially to accommodate was at least a little more filled out than usual.

The train stopped and mercifully the sweatmonster got off. The carriage emptied slightly, and Valerie breathed a sigh of relief, feeling her tight chest bob up and down. She was glad of the space. She moved down the carriage a little, away from the door. It was still fairly packed, but people had naturally separated apart from each other a little to find their own space. Valerie faced towards the door at the end of the carriage, so as to be alone with her thoughts.

As she turned, she felt the tightness in her chest increase, and she looked down – and gasped silently. Her breasts looked much bigger. This bra was amazing! She smiled, and looked behind her to check no one was looking, before hefting them up and down. They even felt heavier. They bulged out of the tight bra, digging the straps into her shoulders and back. This was weird. There actually seemed…more of them. But that was impossible. Valeria put in her headphones, and switched on a podcast. She’d be seeing Simon in a few stops, and she wanted to clear her mind.

As the train rattled along, Valerie felt her chest jiggling a lot more than she was used to. Pulling a headphone out of her ear, she looked down, and this time her heart began to pump quickly and blood began to rush through her system. Her breasts were bulging out of her bra, and what was more – were growing. They were slowly swelling forwards with each breath, and pushing against the incredibly tight bra, which she knew was the cause of this. Looking around, she undid the clasp, as it was about to break anyway, and felt her growing tits flop out, remaining oddly pert, despite the lack of support. It was like they were just…blowing up. Her breasts poked about two inches out in front of her, and her nipples, which seemed a little swollen too, brushed lazily against the fabric of her blouse as her tits jiggled with the bumping of the shirt. Their contact with the blouse shot jolts of arousal around her body. What on earth was going on?

She examined the bra, and couldn’t see anything on it other than on the clasps at the back, which had a strange rotating arrow, on a tiny plastic dial that had numerical values going from 1 to 9. The arrow was currently pointing at 6. She frowned, and put the bra in her bag, watching with some surprise and no small degree of arousal as her breasts slowly bulged forward in her blouse, her growing flesh pressing against the white fabric.

She looked around the train – she had to keep this from the other passengers! What could be more embarrassing?! She had a blue jumper in her bag, but it wasn’t very flattering, and she was seeing Simon soon. She’d ride it out.

No sooner had this thought entered her head, when her breasts swelled forward again, bulging against her blouse, parting the fabric between the buttons as her tits grew outwards, putting strain on the tightening top. She was suddenly struck with how big, firm and heavy they were, as they stretched a full five inches out in front of her. Each rattle of the train sent her melon-sized tits bouncing, and the sight of it turned her on a huge amount. Her big nipples were poking through the blouse in an incredibly obvious fashion, and she felt embarrassed. No sooner had she felt this, when her ass began to swell. “Not you too!”, she whispered, feeling her tight pencil skirt growing tighter and bunching up beneath her growing cheeks. “Shit, I’ve got to get off this train.”

The train was pulling into the next stop, and Valerie turned, accidentally pushing her large breasts into the man behind her. Her hard nipples rubbing into him turned her on a huge amount, but she squeezed her growing tits through the crowd of people, and made her way to the opening doors.

“Valerie!”, smiled Simon, stepping onto the train.

“SHIT.” thought Valerie, loudly.

Simon stepped in, and Valerie tried to step back, to put some distance between Simon and her growing bust. Unfortunately there was no room behind her – why had no one got out at this station!? – and Simon was pushed forwards by the crowd getting on, and before too long their faces were inches from each other. They smiled, awkwardly, as Valerie’s tits swelled copiously into Simon’s chest. If he noticed, he pretended not to.

They made small talk, but Valerie couldn’t tell you what it was. All she was thinking about was the embarrassment of her already big tits swelling forwards, bulging against her tight shirt, pressing further and further into Simon’s chest. Her tits were showing no sign of stopping, swelling and stretching against the fabric, creating big gaps where the buttons were being pulled apart either side from how wide her expanding boobs now were. They were incredibly big and round, and protruded about seven inches in front of her. Not that you could tell, and they were pressed into Simon’s chest by their close proximity, and bulged upwards, almost spilling out of the top of the blouse.

Looking down, Simon could see a vast expanse of cleavage in the gaps between the buttons. Valerie couldn’t know, but the thought was turning him on beyond all belief. From his perspective, it looked like her tits were actually…growing. This was impossible, and yet it was happening, right in front of him.

“So…where are we headed tonight?” asked Valerie, as her huge tits grew into Simon further, almost pushing him backwards. There was now two basketballs between them, and Simon was actually further away from Valerie than when he’d gotten on the train. He was glad of the distance, as for the past few minutes he’d been nursing a colossal erection. He already liked Valerie, but this was beyond his wildest dreams.

“Um, there’s a late night gallery open, I thought we’d check that before going out for a meal then-”

Simon was cut short by the top button from Valerie’s blouse pinging up into his chin.

“Sorry”, said Valerie, blushing. She tried to move backwards, but at that point her ass swelled even bigger, pushing into the guy behind her. He assumed he was being pushed, and pushed back, thrusting Valerie even closer to Simon, pressing her humongous tits into him, bursting another button as they got pressed into his chest, bursting upwards and pressing together. There was just too much of her increasingly huge tits to fit in the small gap, but the closer she was pressed into Simon, the more her tits struggled out of her top. Her face was inches from Simon, despite the colossal breasts pushing him away.

Moving closer to Simon, Valerie’s crotch, already incredibly wet from her sensitive nipples and generally massive state of arousal, pressed against Simon’s huge erection. Fireworks went off in her brain, as she felt his throbbing dick so close to her cunt, and without thinking, she put her arms around him, pulling him closer to her. Her enormous, still swelling tits bulged up, another button pinging off, and she felt his big cock rubbing against her cunt, turning her on an indescribable amount. For Simon’s part, he wanted nothing more than to fuck this goddess.

With three buttons gone, almost all of Valerie’s enormous cleavage was on display. She’d be so turned on by Simon she hadn’t noted how much her tits had grown. It was also hard to tell, as they were so closely pressed up against him. Her ass seemed to have stopped for the time being, but her pencil skirt was dangerously stretched. Her blouse couldn’t take much more growth. There were only a couple of buttons left, and her tits spread out hugely in front of her. It looked like they’d protrude about ten inches in front of her, if only there were ten inches of room. As it was, they squeezed upwards, creating mounds of cleavage that Simon longed to bury his face in and shove his cock between.

“Should we…maybe…” Valerie looked at Simon, her arms still around him, two mountains of breast the only thing between them.

“Perhaps…we should”, returned Simon, his big dick practically cumming with arousal.

“Go back to yours” they both said at the same time, nervously.

They both cracked up, Valerie’s colossal tits shaking and rubbing against Simon, her hard nipples driving them both wild with desire.

“If we get off at the next stop, we can get a cab to mine”, offered Simon, as Valerie’s tits swelled and bulged further into him.

“This train’s getting a little…tight”, agreed Valerie, as she felt the last-but-one button struggle to hold on. Her tits really were tremendous now. She was starting to feel very claustrophobic on this train – god knew who was looking at her. She must have looked like a cartoon porn star, but she felt incredible, and she knew Simon liked what he was seeing. She really knew that.

The train slowly moved towards the next stop, Valerie growing all the time, pushing Simon away, despite her arms wrapped around him. Her breasts, unable to grow outward, bulged upwards, filling more and more room between them, until she noticed with fascination, that they nearly reached her chin. Her nipples were so huge now. She could feel them digging into Simon’s chest like two large bullets.

The train slowly trundled into the platform. Both Valerie and Simon wanted to get home and fuck each other’s brains out, but there was also something uncontrollably arousing about the position they were in, Valerie slowly growing bigger and bigger, swelling into Simon’s chest, and Simon’s dick still throbbing into Valerie’s crotch, rubbing against it, turning her on beyond belief.

Eventually, the train shunted to a halt, rocking back and forth, sending Valerie’s colossal breasts swinging, pinging off another button. She only had one button left, before her tits just swung out in front of her, and that button wasn’t going to last much longer, having to deal with the entire weight of her two huge tits on them.

As the doors opened and the crowd moved slowly towards them, Simon moved back away from Valerie, and her tits surged forwards, finally revealing their true size. Standing on her own, they bulged forth a good thirteen inches in front of her chest, looking truly titanic, even on her tall frame. Even on a solipsistic subway journey, people were turning to look and admire her tremendous frame. She felt them still swelling and bulging forward against the incredibly tight fabric, so moved quickly off the train with Simon.

On the station platform, she felt a little less trapped, even though her breasts showed no sign of slowing their incredible growth. She wobbled and bounced towards the escalators.

“Have you got anything I could wear?”, she asked Simon. “I was going to put on a jumper a while back, but I just don’t think it’ll fit”. Indeed, she produced it, and they both laughed. It looked like a child’s jumper next to her tremendous mammaries, which were still noticeably growing, as they walked along. “I don’t think this blouse’ll last much longer.”

The last button was looking incredibly sorry for itself, with the sheer width of Valerie’s huge tits pulling the fabric apart to stretching point on either side of the button. An enormous, now-thirteen-inch expanse of cleavage was visible in a titanic trench on top of Valerie’s chest, and the few inches that were covered by her blouse, which had ridden up over her stomach, as so much of it was needed to cover her tits, were not going to last long.

“I don’t know what I can offer – you’re just so…big”, said Simon, his erection throbbing. “Maybe this?”

He took off his jumper, a large baggy brown affair, and handed it to Valerie.

“Could you…help me?” she said, sweetly, looking up at him. His heart melted.

Getting the jumped over Valerie’s head and arms was easy, but it took all of the jumper’s, and Simon’s strength, to pull it over Valerie’s still growing chest. Valerie could feel her blouse giving way as the jumper stretched and pulled over her unbelievable bust. It now bulged out fifteen inches in front of her, and wobbled and jiggled with every step. But at least Simon’s jumped just about covered it, even though it couldn’t stretch much over the huge round base of her jugs. They could both see the stitching begin to give already, so they made tracks.

“Thanks”, smiled Valerie, really meaning it.

Simon smiled back, and took Valerie’s hand, as they left the station, Valerie having really trouble with the subway gates. She could barely fit inside the rotating metal gates, her growing breasts almost getting stuck, but with a bit of a push her huge tits and bulging ass squeezed through. They practically jogged up the steps to street level, Valerie’s enormous breasts jiggling and wobbling with every step. The brown jumper was already beginning to rip.

On the street, Valerie hailed a cab in seconds flat. It turned out ludicrously big breasts were a good way of getting a cabby’s attention. Valerie somehow squeezed her enormous breasts through the door. Inside, Simon gave his address, and they sat back, Valerie’s tremendous chest heaving, straining against the jumper, her tits clearly still bulging and growing forwards, her ass massive and full. There was a ripping sound, and a tear began to form in the middle of the neck of the jumper. A huge expanse of wobbling, still growing cleavage was revealed beneath.

“Sorry about your jumper”, said Valerie, her eyes fiery and full of arousal.

“I have never been more aroused”, responded Simon, his mouth dry.

“Would you like them…bigger?”, ventured Valerie. She was excited and aroused beyond belief.

Simon nodded in vague disbelief.

Valerie grabbed the bra from her bag, and showed Simon the dial. She turned it up to ‘9’. She felt the tightness in her chest increase, and the jumper tore down the middle. The growth in her breasts increased.

Simon threw a bunch of hastily grabbed notes at the cab driver in preparation for what he was about to do, and tore off his clothes, while Valerie struggled to take her skirt off. She realised with a thrill that she couldn’t see anything below her titanic breasts.

Simon did the honours, and in seconds had thrust his big cock into her tight, incredibly wet cunt. He sucked on her growing nipples as her breasts expanded in his mouth.

They both came in seconds, hugely and shudderingly.

They looked into each others eyes, the incredible lust not even remotely sated.

“I’m going to fuck you all weekend”, said Valerie, as her humongous tits grew even more into Simon, taking up more and more of the diminishing space.

“If you can fit out of this cab, I’m quitting my job”, said Simon.

They both smiled. It was win-win either way.
