Kyra sat at the edge of Jessica's bed. She looked at her as she got ready, applying makeup and adjusting her clothes. Jessica groaned a bit.

“Shit. This bra's getting tight...” she muttered.

“God, yours are STILL growing?” Kyra asked jealously. “How big are they now?”

“Bigger than a C-cup, that's for sure.” She stretched a bit. “While we're out, I should get some new ones. Probably a D at this point.” Kyra looked down at her own breasts in disappointment. They had stopped just barely above an A-cup.

“You're lucky, y'know that, Jess?” Jessica looked from the mirror to Kyra.

“Yeah, I guess. Sometimes I think I think guys only like me for these.” She pushed them up.

“Still, I'd kill for boobs like those.” Kyra stood and went to the door. “Ready now?” Jessica nodded, and they headed out to the mall.

**AT THE MALL**

“How's this one?” Jessica asked Kyra inside the dressing room of the Victoria's Secret, presenting her new lacy brassiere.

“Hmm...looks a little snug on the sides.” Jessica looked down and nodded. “Are you getting anything while we're here?” Kyra shook her head.

“Why bother? These ain't getting any bigger.” She held up her lackluster assets.

“C'mon. Treat yourself.” Jessica encouraged her. “I'm gonna go look for another one. You should too, for yourself.” Kyra sighed, then went throughout the store, gazing at the merchandise. She found a couple ordinary ones, nothing special.

'I guess its nice that I can find bras easy...' Kyra thought. 'But still...I wish I had Jessica's boobs...' Just then, a certain bra caught her eye. It was on the racks, like all the others, and seemed to be the last one. It was simple and white, but the strange thing was the green button in the center. She picked it up, studying the tag. 'Hey! Its my size!' She kept reading, and read the peculiar information:

“Have whatever size you want with Bra Option Plus!”

Kyra looked at it questionably. 'Yeah right...' She thought. 'But...it looks nice enough. Better try it one, though. She went to the fitting room and stripped down. She tried some of the others first, making sure they fit correctly, then she moved on to the special bra. As soon as she put it on, the green button in the center lit up, and showed the letter “B”.

“What the hell?” Kyra whispered out loud. She pulled the tag out from the side of the bra and read the additional information. “Instructions for use:” She read aloud quietly. “Press button in center to advance a size. Each press of the button adds one cup size. Warning: Bra can only be removed when growth is complete.” Kyra paused, then dropped the tag. She scoffed. “Probably an inflatable bra. How lame...” She investigated the bra a bit. It was pretty low cut, revealing what would be her cleavage, if he had any to show. She couldn't find any pumps or packs. She shrugged. “Why not?” She pressed the button and the letter changed from “B” to “C”. She hesitated, nothing happening. “Stupid thing. Shoulda kno-” She was cut off by a tingling sensation in her boobs. It wasn't strong, it was just a slight prickle, just barely enough to feel it. But it was building slowly.

“Oh , whoa...” Kyra smiled, touching her now warm and perky breasts. “That feels...unnhh...wow...” Kyra couldn't help but moan as her nipples pointed through the bra, and as the sensation reached its highest point, her breasts slowly began to grow. Kyra gasped. “Now way...its working! I can't believe....OHHH-” She threw her hand over her mouth, remembering where she was. The pleasure seemed to reach its crux, they had inflated all the way to the guaranteed size: C-Cups. She had cleavage now. She had a seductive silhouette. She still couldn't believe it. She looked at the tag again, seeing if there was anything she had missed. “'Once they grow, they can never grow back. Bra Option Plus can only advance in size.' Hmph, as if I would want them to.” The bra then seemed to shift over her boobs, and extended to a point where it fit. “Huh.” She posed in the full length mirror, pushing them up and out like Jessica did before. “Looks like you've got some competition now, Jess.” She heard a knock on the door.

“Kyra? You ok in there?” Jessica asked. Kyra fumbled and got the bra off. She threw it in the pile with the others.

“Fine.” She replied, then looked in the mirror to see her new breasts, now completely uncovered. Her smile broadened. “Really fine.”

“Let me in then!” Jessica tugged at the door.

“Oh, uh...” Kyra fumbled for her shirt, quickly throwing it on. She didn't have time to realize how tight it was before she unlocked the door and picked up her new magic bra. Jessica's jaw dropped.

“Where did those-” Kyra grabbed Jessica by the arm.

“I'll tell you when we get to your place. Now let's check out and get outta here.”

**AT JESSICA'S**

Jessica and Kyra rushed into Jessica's room. The door slammed shut and was quickly locked, just in case. Jessica turned to face Kyra.

“Explain. Now.” She pointed to Kyra's perky chest.

“You'll never believe this.” She took the magic bra from the bag, took took her shirt off, then strapped it on, and it fit perfectly. The button glowed with the letter “C” in the center.

“What, is that a future bra?” Jessica joked.

“Kinda, yeah.” She pressed the button and waited. The “C” then changed to “D”, and Kyra could feel the familiar sensation pouring into her breasts. “Onnhh...God, that feels...” Kyra stumbled a bit, and the bra began to work its magic once more, her breasts beginning to plump up, quicker than before. They swelled from apple sized to grapefruits.

“Holy shit!” Jessica was dumbfounded.

“I know righ...unnhhh...” Kyra couldn't finish her sentence. “Oh, It feels even better than before...” The fabric of the bra began to stretch and strain, and Kyra was worried whether or not it would hold. Soon, they finished, Kyra's moans slowly fading, her cleavage spilling out of the now tight bra. But in a matter of seconds, the bra shaped and morphed to fit. Jessica just stood there and watched Kyra as she posed in the mirror. She could barely comprehend what had just happened, but she suddenly had an idea.

“Hey, so...you got...D-Cups now, right?” Kyra nodded and continue to pose with her new gifts. “You should let me try it out. I mean, it'd fit-” Kyra turned, stepped back, and scoffed.

“Yeah right. I bought this, so its mine to use. Don't want you stretching it out.”

“Oh, c'mon. Look, I just wanna get a bit bigger-”

“Wait, what? What happened to the whole 'Guys only like me for my boobs' thing? Were you just making all that up?”

“No, I mean...boobs aren't everything, but...guys do kind of look at them. A lot. And they won't look at mine if they're looking at yours...”

“I knew it. You're so fake sometimes, y'know that?”

“Shut up, Kyra! You flaunt as much as I do. You wear shorts showing off your ass all the time.”

“So what? I like...wearing shorts.”

“Bull. You're compensating and you know it. I can't be hanging out with you looking like that. Nice ass and tits? That's a double knockout. I can't compete, and I can't be losing guys to you, so just hand over-” She stepped over and grabbed at the bra.

“Back off, bitch. This is mine.” Jessica gripped hard onto the center of the bra and began tugging on it.

“C'mon, just one...cup...size!” They played tug of war, both pulling one way or the other, until Jessica finally lost grip and they both went flying back. Kyra slammed into the dresser as Jessica flew to the floor. Jessica looked up at her, and noticed something that horrified her. “Oh...um...Kyra.” Kyra whipped around to face the mirror and her mouth fell open.

“J? J-CUP?!” She turned to see Jessica. “You bitch! You did this!”

“I'm sorry, really, I didn't mean-”

“Shut up and get it off me before...” It was too late. Kyra began to feel it, and it was rushing quickly, building and building higher than ever before.

“Oh God! Hurry...ooooonnh...” Jessica rushed behind Kyra and began to pry at the clasp but it wouldn't budge. She fiddled and prodded as much as she could, trying to remove it as Kyra's moans grew louder and more emphatic. She could hear the bra creaking and groaning, getting tighter and tighter as Kyra's breast flesh began to build up inside it. Jessica tried, but she couldn't undo it.

“Its stuck!” Jessica yelped at Kyra. “What now?” Kyra remained silent, her moans seemed to drift away.. “Kyra? Are you ok?” She went to face her, only to see Kyra breathing in heavily, her breasts moving up and down with every breath, their inflation boosting with each moment. Kyra's breath became gasps and then coos. Her face cracked out in a coy smile as she saw her now cantaloupe sized boobs straining the bra to the max. Jessica looked at her quizzically. “What're you...?”

“Y'know..these aren't so...unnhhh...so bad after all.” She put her hands onto the flesh overflowing from the edges, both above and below her bra. She squeezed, and her eyes shot open and rolled back in her head. She started to get looser, her body limp and leaning against the dresser. “I mean...God...I've never even had an orgasm like this...its just...all over...UNH!” She shouted in pleasure as her mounds jutted forward, the bra almost snapping in two. They were the size of round watermelons when the bra finally snapped, her breasts shooting forward to their free form size.. The bra slipped to the ground, and Kyra sat there in rapturous bliss, the world non-existent, as she came down from the greatest feeling she had ever had.

Jessica stood for a second. “Kyra?” Kyra didn't respond. She seemed to be unconscious, with the biggest smile on her face, even though she somehow rubbed all over her boobs and even tweaked her nipples. Jessica waved her hand in front of Kyra's face, with no response. Jessica crouched, and reached around Kyra's rag-doll like body, and grabbed the bra. She unlocked the door, left the room, then went into the bathroom. She inspected it, thinking it had busted, but she was still hoping to fix it. She took the bra, still clasped, and wrapped it around her body, connecting the button to what seemed like a slot to the other side. She waited, and saw the familiar glow of the button with the letter “D”.

Jessica grinned broadly.

“This is gonna be fun.”

Jessica stared at herself in the mirror, the only article of clothing on her upper half being the magic bra. She reached for the button, but hesitated, thinking of how big Kyra had gotten. “Jeez, she got...HUGE. Bigger than I want. I gotta be careful with this. Just one press, then I take it off.” She pressed the center button once, seeing it go from D to E. She awaited the feeling, the rush that Kyra had gotten. She had seen it in her eyes, heard it in her voice. She couldn't wait to feel it too. Any second now. Any minute the rush of hormones would...come and...and...

'What the hell? Why is it not working?” She looked down at it, seeing nothing but her regular D-cup breasts in a skin tight bra. After closer inspection, she had seen the letter had changed from not D to E, but D to ER. “ER? What the hell does that even mean?” She thought for a second, then slapped her forehead with the palm of her hand. “Er. Error. The thing is busted. Dammit! When it broke, the wiring must have messed up. Great. No big boobs for me, I guess.” She attempted to unlatch it, but had trouble with the clip. “Damn, why is this so tight?” She pried and stretched the clasp, but nothing worked. It wouldn't budge. “Oh, whatever. The bra is comfortable enough. I'll worry about this tomorrow.”

Jessica went to bed in disappointment, ready to put it all behind her and welcome the next day.

* * *

“You know...” Kyra said dreamily. “These aren’t so bad” She stroked her basketball sized breasts in pleasure. Jessica looked on in discomfort and unease. She watched Kyra stroke them in euphoria, shaking in pleasure.

“Jeez, yours are pretty...huge, Kyra...” Kyra smiled, then pointed at Jessica.

“Not as big as yours! I'm so jealous!”

“Wha...?' Jessica looked down to see her breasts the size of bean bag chairs-and still growing! She let out a long scream and grasped them close...

Jessica jumped forward into a sitting position in her bed. In a cold sweat, she looked down at her breasts. They remained the size they had been before she had went to bed.

“Whew...” She sighed in relief at first, then frowned. “Not beanbags but...still...NOTHING? Not even a LITTLE bigger?” She took the covers away from her body and sat up straight on her bed. “I can't be hanging out with Kyra with these. I mean, I need to be at least a little bigger to stand a chance around guys with her...” She began to think about her options. “I mean, we could stop hanging out in public together...but we always find guys together...its like...our thing!” She continued to mumble out loud to herself as she did quite frequently, stroking her hands through her long black hair delicately. “But I just...can't compete with those. I need them bigger...” She crossed her arms across her chest and squeezed, her boobs only covered by a loose night shirt and the broken magic bra. “Maybe they sell more of those bras at that store? Its worth a shot. Hell, they might even have some panties that could do the--”

She stopped mid-sentence due to a tingle forming beneath her crossed arms. Mixed with that tingle was a slight and almost unnoticeable pressure against her arms as they laid across her bosom. She felt the fabric stretching across, sliding up and out around her gradually growing grapefruits. Her arms flew off her chest as her smile broadened, fully understanding the events transpiring.

“OH YES!” She shouted and jumped out of the bed. She sprinted to the bathroom, ready to view her blossoming breasts in all their glory. By the time she got to the mirror, though, they had stopped, about the diameter of a DVD. She pouted a bit, then nodded. “Shame I couldn't watch them...” She patted them on the side, feeling their sensitivity shoot tingles throughout her body. She lowered her hands, not wanting to go too crazy. Her loose night shirt had gotten noticeably tighter around the chest, raising to the point where the very edge of her light blue panties could be seen if she moved in even the slightest way. Her smile couldn't leave her face as she took of the night shirt, seeing that the bra had already stretched to fit her as it had done for Kyra before. “I gotta see them in full!” She brought her hands to the clasp and attempted to unlatch it, but to no avail. “Still stuck?” She frowned, bringing her hands forward to her sides, then to the bottoms of her breasts, bobbing them up and down in a juggling sort of way. “...but this means I need a new wardrobe!” She picked up her phone and contacted Kyra.

“Wanna go clothes shopping tomorrow?”

**AT THE MALL, THE NEXT DAY**

Jessica threw a red top over the side of the fitting room door.

“Too small!~” She sing songed to Kyra. Kyra took it off the door and smirked

'Welcome to my world.” She tossed it into the pile of no fits, being significantly larger than the pile of clothes that actually fit. Kyra wore a tight pink blouse, barely covering her navel. The cleavage was spilling out of the edges of the u-shaped neck of her shirt, and with no bra holding them in, her nipples were taut and noticeable through the fabric. She had a pair of white booty shorts to accommodate the pink blouse, accentuating her perfect heart-shaped ass. “I'm lucky I even have a few shirts that can fit over these monsters!” Jessica laughed, then opened the door to show Kyra a cotton tank top, lime green and form fitting, showing off her tan belly and a wide amount of cleavage. It had a flower pattern printed on her left breast, being stretched to the point where it was almost unrecognizable.

“What do you think?” Kyra studied her up and down with a face of deep thinking. After a second, she nodded.

“Yeah, looks nice.” Jessica giggled and jumped up and down, causing her titanic tits to bob and sway in all directions. “Can you believe the bra still worked?” Kyra laughed a bit.

'The way my boobs abused it? Hardly!” Jessica laughed a bit as well.

'The reaction was delayed, but still, can't argue with the results.” She spun around, giving Kyra a nice view of her well rounded ass in her high cut jean shorts, before bringing her breasts back to the front on the end of the spin. Kyra rolled her eyes.

“Yeah, yeah. Let's go check out.” They started to make their way to the counter, Jessica back to wearing her white tank top, the shirt almost busting at the seams. It was surprisingly the only one that fit before she left the house. But Jessica began to feel a familiar tingling in her boobs.

“Umm...hold up a sec.” Jessica gestured to the restroom as they made their way inside quickly.

“Pit stop? Its cool, I needed a touch up too-”

'No, its not that, its...um...unnnhhh...” Jessica bean to moan all of a sudden, bringing her hand to her mouth and making a slight 'slap' when it finally covered it. Jessica looked cautiously at her chest to see that it had began growing again, this time at a bit of a quicker pace than it had the first time it worked. She let out a quick scream.

“NO! What the hell? I thought...I thought it was...unnnhhh...Kyra HELP!” She felt her breasts pressing against the fabric of her fragile tank top. Their speed continued to rise as her breasts reached the size of Jessica's head, about G-cup size when she began to hear rips emanating from her body. The first came from underneath her right breast, a sliver of the white bra began to peek its way through the hole.

“How? I can't!” Kyra shouted back as she watched in awe. Another rip formed in Jessica's shirt, a more prominent one in the front of her right breast, letting her nipple take on an even more defined shape, still covered by her magic bra. Her shirt began to distort their shape, pushing her breasts upwards towards Jessica's face, making them seem almost ovular. The bra somehow grew along with her breasts, keeping them fully covered throughout the growth.

“Why...is this...happening? I only pressed it once! I should've only...onl...ohhhh...” Jessica was struggling to keep her mind together throughout the pleasure coursing through her body. The tears continued to multiply in her shirt some joining and becoming larger and larger as her breasts reached I-cup territory.

Just as they breached the next letter in the alphabet, her shirt tore to pieces, allowing her breasts to return to a more spherical shape, flopping up and down as they accepted their new found freedom. Jessica looked down in terror and saw that the bra was still big enough to cover her now basketball sized mammeries. The feeling ebbed away and her breasts soon halted in size. Jessica looked down in horror, seeing her breasts now engorged beyond recognition.

“I...never wanted them like this...” Jessica pouted. Kyra smirked a bit.

'Yeah, I didn't either. But hey, you'll get used to them. Just give it a little time. I only really needed a day. At least the bra still fits.” Jessica looked down and pried at the clasp, but it still wouldn't unlatch.

“This thing needs to go.”

**AT JESSICA'S**

Jessica, home alone, decided to take drastic measures. She pulled a pair of scissors from the drawer and tried to cut the bra by the straps. She managed to get the blades underneath the strap, and tried to cut through, but it was no use. It was as if the bra was invincible. She looked in the mirror and saw the ER still brightly lit in the center of the bra.

She rubbed them a bit, feeling the tickle of pleasure run across her chest.

“They feel nice...I suppose. That's kinda good...” She tried to stay positive as she returned to her bedroom from her bathroom, and layed upon the bed. She thought to herself for a bit. Maybe it wasn't so bad. She'd get used to it in no time, like Kyra had said. She just needed a day or two. And they were pretty sexy, when she thought about it. No one else had these kind of boobs, except Kyra. And now she could hang with Kyra and get just as many guys! Maybe more!

“Yeah, this might not be so bad after all! She smiled. But the smile slowly diminished as she felt a feeling slowly creep back over her. She stopped rubbing her boobs, to see if that was the cause, but felt the sensation rise and rise once more.

“No.” She felt her nipples become taught through the bra padding. “No!” She could feel the straps get tight around her shoulders. “NO!” She could see the cleavage spilling out of the top, the bra beginning to stretch with her now cambering cleavage. “NO-UNNNNHHH!” She tilted her head back and moaned loudly as her boobs accelerated in growth every second. She brought her hands to them, rubbing and fondling them all over, almost impulsively. They were getting to the size of dinner plates, ones used for thanksgiving feasts, and she tried to talk herself calm. “I-I-Its okay, Jessica...” She stammered nervously as her boobs outgrew medicine balls and spilled onto the bed, getting further down her body than her ribcage. Their shape remained spherical somehow, gravity not effecting them in the least. “They'll stop soon. I mean, they got pretty large last time, but I don't think they'll get TOO much bigger...” She felt the speed accelerating at an even more rapid pace as it seemed she was growing a centimeter every second, her breasts starting to outgrow the bra slightly, showing more and more flesh from the bottom and the top of the bra. “...right?” She tried to keep her hands away, the growth itself almost being too much for her, but before she knew it, her fingers were digging into her once more, almost ripping apart flesh as she moaned. They had reached almost the diameter of hula hoops, and she could feel herself leaning upon them, her body arching as it was lifted by the ever-growing flesh that continued to spill from her ever-shrinking bra.

“Oh God...they're not gonna stop are they?” Jessica realized in fear. She desperately tried to wriggle her way to her feet, but she was pressed ever higher to the ceiling, her legs being gradually consumed by breast flesh. They were soon the size of bean bag chairs, and still growing. “Why couldn't they have stopped there?” She questioned in vain, recalling the dream she had had just a little while ago. The bra began to creak, digging more and more into her shoulders, the speed in which her bosom expanded being too much for it. “Ohhh...Oooooooohhhhh....Oh-OOOUUUUHHHNNNN!” She let out fierce cries as the bra snapped off, the size being too much for them. She felt the bed sink down, collapsing under the weight of her new breasts, sending ripples through the mountain of flesh she had obtained. She panted and sighed, slowly losing consciousness...

* * *

“Hey Jess?” Kyra walked into Jessica's house, knowing Jessica hardly ever locked her door. “You left one of your shirts in my bag!” She explored the rooms, going downstairs to Jessica's bedroom. “Jess?” She turned the doorknob and pushed, feeling it jam almost immediately. “Uh...Jess?” She peeked through the crack of the door, her eyes widening and her jaw dropping to the sight of the two SUV sized breasts lying on the other side of the door, Jessica pressing lightly against the ceiling. She looked down at Kyra and waved weakly.

“Remind me to never mess with your stuff again, ok?”

THE END
