Mistakes Were Made

Mistakes Were Made
by Joe Monday

The original concept behind this story comes from another that I read on the internet a long time ago. I've searched and searched and never found it again to credit the original author. The original concept was very simple -- girl takes an experimental BE formula and inflates more than she expects, then discovers that the antidote has spoiled and she might be stuck. It was supposed to be continued, but never was. I've taken the concept and added characters, development, and a lot more than just the single original scene to turn it into a much bigger story. I hope you like it.

Erin came home to find her apartment empty, as she expected. Her roommate Stacey was probably going to be out for the rest of the evening, night, and into the wee hours of the morning, club-hopping, drinking, and who knew what else. That was good, because she had plans with her boyfriend Jeff for the night, including a surprise for him.

She set a cooler down on the kitchen table and took out three small test-tube racks, filled with small vials. Two each held five vials of an orange-tinged liquid, and the other held four vials of a deep blue-colored liquid. The one holding the blue liquid had been buried deep in the ice in the cooler, and she immediately moved those into the fridge, pushing aside a large collection of unknown leftovers and various beer cans to find a place to wedge it in. She put one of the racks of the orange liquid beside it, too.

Her friend Kathy's words were ringing in her ears. "I can make more of the formula all day long, every day, and it's OK for a while at room temperature. But the antidote takes forever to distill and I can't make much of it at all at a time. And it has to stay cold or it goes inert. So put it in the fridge as soon as you get home. Don't let it sit around."
OK, so the antidote is safe, Erin thought as she shut the fridge door and then emptied the ice from the cooler into the sink. Now for the fun part. She picked up the remaining rack of vials containing the orange liquid and headed for her bedroom.

Her friend Kathy was struggling through her chemistry major in college, bored with most of her classes and hoping she could figure out something to do with herself once she graduated. Erin, who was majoring in marketing, had been talking about how fashion and cosmetics and sex appeal were always booming areas, and Kathy had seized on the idea of a cosmetic formula that kept the skin soft and supple and firm, like collagen injections, but something that could be taken in pills or liquids without needing needles and doctor appointments. Sure, it was something that the industry had been trying -- and failing -- at for ages, but Kathy found some obscure references in journals, and a contact at another college, which lead to what she had so far. A formula that kept the skin soft and elastic, and caused a spongy tissue to form under the skin. It worked especially well on women's breasts.

A "boob job in a bottle" sounded like a great idea, but Erin cautioned her that if it was a one-time dose, it would be popular, but women wouldn't buy any more once they had grown a cup size or two. To be profitable, it should be a temporary effect, and give women the option to be bigger or smaller as they wanted -- and they'd keep buying the product.

So now, Erin had the first batch to test of the breast enlarger formula in her hands. Her boyfriend Jeff would be visiting too, and she'd have a knockout surprise for him. Jeff liked big boobs. In spite of that, he was quite happy with Erin's B-cups and they'd been dating for ages. If anything, Erin was more interested in her getting bigger than Jeff was -- although he wasn't likely to object.

Hmm... Should I surprise the heck out of Jeff with a huge rack as soon as he gets here, or should I tease him with just a little and then let him give me more once he finds out? Erin decided to go with teasing him. She opened one of the vials and drank down its contents. The formula was bland and nearly tasteless. Kathy wasn't exactly sure how much effect one dose would have yet, so she'd provided plenty of the BE formula. If anything, it meant there'd be a supply for several evenings of fun. The antidote tucked away in the fridge was to negate the effects, so after a night with stripperiffic melons from Jeff's wildest fantasies, she could go back to looking respectable for classes. That was the plan, at least.

In a moment, Erin felt some warmth and tingling in her breasts, and her nipples were definitely aroused and pressing into her bra. They were definitely C's, maybe even approaching D's, and quickly making her bra uncomfortable. She unbuttoned her blouse and freed them of the now-too-small bra, admiring them in the mirror. The BE formula definitely worked. She had a set of either larch C's or small D's, bouncy and perky. Her nipples were larger, and longer, too, and her aureolas had grown in proportion as well.

She fondled them for a moment, enjoying the sensation of having more of herself. Then she grabbed a snug-fitting tank top and pulled it on, noticing how it emphasized her newly-enhanced assets. Jeff was going to love this, she thought.

Erin was tidying her shoulder-length brown hair when the doorbell rang. She jogged to get it, discovering how good it felt as her newly-enhanced boobs bounced with each step. "Hey, Jeff!" she said as she opened the door.

Jeff gave her a quick kiss and hugged her, and Erin felt his body tense as her new endowments pressed into him. He stepped back, closing the door behind himself, and looked at Erin. "Is that some fancy new bra you bought? Wow!"

Erin smiled. She pulled the tank top over her head, making her boobs spill out, fully on display.

Jeff cupped them in his hands, gently kneading them and fingering her firm nipples. "What happened...?

Erin pushed them into Jeff's eager hands. "Kathy gave me her breast enhancer to test. Like the results?"

"Yeah!" Jeff agreed, seemingly unable to take his hands off.

"Well, come with me." She led him back to her room, where she picked up another vial and opened it. "Watch this!" She downed the contents, and as Jeff watched, her boobs swelled more, growing to double-D size and maybe beyond in a few seconds.

Jeff grinned. "That's amazing! ...But, um, are you OK with pornstar boobs?"

"That's the best part!" Erin laughed. There's an antidote. So it's not permanent. It's just for us."

Jeff was already undressing, and Erin was ditching the rest of her clothes, too. Jeff moved on to gently kissing her nipples and sucking on them, which was making Erin feel even hotter. After a few minutes of lovemaking, Jeff looked over at the rack of three remaining vials. "A little more, maybe?"

Erin smiled and held his gaze as she downed one more vial. Her whole body felt warm this time, and her DD chest swelled again, passing any rational bra size. Their size and weight finally made her breasts hang down somewhat under their own weight, looking more natural then silicone fakes, but still impossibly huge. They bobbled and swayed with every move, nearly bringing her to orgasm from their motion alone.

Erin leaned back and fell onto the bed, her enormous boobs bouncing and sloshing as Jeff joined her on top to suck and caress them. "You're amazing," he whispered, as they started what would be a full evening of joyous lovemaking.

*          *           *

Erin woke up close to midnight. She sat up, basking in the sensation of her huge breasts resting in her lap. They weren't heavy. Just soft, bouncy, and very sensitive. She played with her still-erect nipples, big as the end of her thumb, atop saucer-size aureolas. This body was impractical as hell, but so much fun. She looked over at Jeff, who was still asleep, and back at the remaining two vials. Jeff would have to go to work in a couple of hours. Erin wondered... would he like her to be even bigger? Would I like to be bigger, she wondered? Why not?

She drank down the contents of the last two vials. I'll give Jeff the thrill of his life before he goes to work, and take the antidote in the morning. Once again, a peculiar warmth flooded Erin's body. She could feel her breasts swelling as the effect took hold.

This time, though, something different happened.

The warmth in her breasts subsided as it always did, as they grew, filling her lap and spilling onto the bed. But the warmth persisted in her belly. And then her breasts started to rise on her chest, pushed up by something. Erin looked down to see her flat tummy rounding out, growing, swelling like she was pregnant. She gasped, then whimpered as a new sensation consumed her. Her belly was increasing in size, to several month's pregnant and beyond. It pushed her boobs aside, growing like a yoga ball inflating inside her. She rubbed her swelling tummy, feeling incomprehensible, delightful sensations. Carried away, Erin moaned quietly and rocked in place, caressing her swelling self.

Jeff stirred and blinked, trying to focus on much more of Erin than he thought should be there. "Wh... What?" he mumbled.

Erin broke out of the flood of sensations long enough to moan, "Ohhh... I'm getting huge..."

"Oh my...!" Jeff came to a full realization of what he saw. Erin's belly was swollen easily three feet across, pushing out between her massive breasts, each about two feet across themselves. "What happened?!?"

"I took the last two formulas..." Erin panted. "I wanted to make my boobs bigger for you... and this happened..."

Jeff stroked Erin's bloated belly, getting visibly aroused as he did. "You know, this is... kind of hot..."

Erin rolled him over on top of herself. Her belly wasn't hard like pregnancy -- It was soft and yet still firm, more like her breasts. It moved and jiggled but sprang back to shape. Jeff's body sank slightly into her massive form as he found his way inside her while pillowed on her huge beanbag belly.

It wasn't long before both of them were satisfied in a way neither had even known existed. Jeff rolled off of Erin's inflated form, watching her belly and breasts wobble with the motion. "I could watch you all day," he sighed, idly making her tummy jiggle with one hand.

"Yeah, but you've got to go to work, and I've got to take the antidote that Kathy made and go back to normal," Erin said.

"Too bad," Jeff said as he got dressed. "I could get used to this."

Erin smiled. "Well, I've got another supply in the fridge. So maybe another night next week. I still don't know how this happened," she said, patting her soft, distended belly. "Kathy said it was just to make my boobs grow. This was totally not what I expected."

"But fun," Jeff added, giving her a kiss and another jiggle-inducing pat on her bare belly. I'll see you later tomorrow.

"OK," Erin answered. "I'm going to get a little sleep. See you later."

Jeff let himself out, and Erin tried to roll over to get a little sleep. It wasn't an easy maneuver involving much sloshing about and waves through her breasts and belly that sent new ripples of pleasure throughout her body, but she was tired and fell asleep shortly.

*           *           *

It was 5 AM when Stacy got home, bleary, buzzed, and unsteady from partying all night. She needed a snack and something more to drink. She tossed her keys on the kitchen table and opened the fridge, rummaging for anything appealing. A beer came to hand immediately; she popped it open and gulped some down while she fished around for something to eat.

"Geez, all kinds of junk in here but nothing good to eat," Stacy grumbled. "What the heck is this crap? Science experiments?" She grabbed the test tube rack that contained the two vials of blue liquid and carelessly cast it onto the nearby table, out of the way while she rummaged deeper in the fridge, depositing several containers that looked suspiciously like they'd hung around too long onto the table, and then came up with a couple of slices of leftover pizza. She slammed the fridge shut and flounced back to her room, locking the door behind her like she always did. When Stacy was drunk and tired, she didn't want anyone to wake her until she was well past the hangover stage.

The questionable leftovers were still on the kitchen table. And so were the vials of Kathy's antidote formula.

*           *           *

Erin woke up a little after 10 in the morning. For just a moment she thought something was seriously wrong when she had trouble sitting up in bed -- then the memories of the night with Jeff came flooding back. She was still huge -- jiggling breasts and fat, bloated belly making her hot with every movement. It was fun, but she had to get back to normal for classes. She lurched to her feet, belly wobbling and making her boobs bounce and jiggle in the process. Erin's bathrobe barely closed in front, but she tied it as always out of habit.

Erin poked her head out her door. As she expected, Stacy's door was closed, and the sounds of her snoring as she slept off another bender echoed into the hallway. Erin semi-waddled out to the kitchen, trying not to stir up too many waves in her body that might distract her. She could tell Stacey had been poking around in the fridge -- nothing was where she'd left it. Erin rummaged and hunted around, but she couldn't find the antidote vials. Confused, she looked around, and then something caught her eye.

On the kitchen table, next to some plastic containers of unidentifiable leftovers, were the two vials of antidote.

A chill ran though Erin's body as she snatched up one of the vials. It was quite warm, and no longer deep blue. It was pale blue, almost clear. Desperately, she opened one vial and drank it down, hoping something would happen, that it might still work.

Nothing.

"No, no, no, no, NOOO!" Erin muttered, attempting to run down the hall, struggling against the movement of her bloated belly and boobs. She pounded on Stacey's door.

"Stacey!" she yelled. Nothing. Erin banged on the door again, tried the doorknob and found it locked, as she expected. "STACEY!" Still no response. More knocking and yelling. "STACEY! Wake UP!!"

"Go 'way... Sleeping..." Erin could hear Stacey mumble, half-coherently, and the sounds of blankets rustling as she no doubt buried her head underneath. There was no more response to any more calling or knocking; Stacey had definitely gone back into deep sleep -- if she'd ever really been coherent at all.

"Dammit..." Erin muttered, and waddled back to her room, closing the door behind her. "Gotta call Kathy..." She fumbled on the nightstand for her cellphone and dialed her friend's number. The line rang, rang some more, and then the line picked up. "Hi Kathy..." Erin started speaking breathlessly.

"Hi, this is Kathy. I'm sorry I missed your call..." the voicemail message started talking over her.

Kathy hung up, and dialed again. "Pick up, pick up, pick up..." she muttered as it rang. The voicemail answered again. Erin hung up and tried one more time. Still voicemail. This time, she left a desperate message. "Kathy, it's Erin. Call me back right away. I think the antidote is ruined and I don't know what to do. I'm stuck! Call me back!"

Erin sighed and flopped back on the bed, which she probably shouldn't have done since it sent her boobs flopping back under her chin while her belly sloshed in ways that put interesting pressure in places she really didn't want at just this moment.

Please, call back Kathy... I don't want to be stuck like this... Erin closed her eyes and tried to stay calm, waiting for the call.

*           *           *

Stacey finally woke up, hungry again. She combed some of the tangles out of her messy blond hair, headed out to the kitchen and pulled the fridge open. There had to be something decent to eat. "Stupid leftovers. Geez, Erin, you were supposed to go to the grocery store yesterday. What gives?" She stopped rummaging when she came to the rack of BE formula still in the fridge. The vials looked a lot like the ones she sometimes bought at the clubs -- ectasy or some other party drug dissolved in a shot -- but the color wasn't anything she'd seen before. A handwritten label taped to the rack read "Breast Enlarger" with a date from a few days ago.

"What the F...?" Stacy wondered. "Breast Enlarger?" She looked down at her almost-B's and snorted. "Can't buy groceries when you're supposed to, but you blow money on this stuff?" She pulled the vials out, opened all five, and gulped the contents down at once. Payment, Stacey thought to herself. Let's see if this stuff's real.

In a few seconds, a warm feeling spread from her chest to the rest of her body. Her nipples stiffened, poking noticeably into the thin material of her oversized t-shirt. They started to swell, growing into D's and DD's. Stacey grinned, cupping them in her hands. Geez, how much are they going to grow? she wondered, as they kept swelling, hanging a little lower as they grew to beach-ball size and more.

Stacey's growing boobs bounced and moved in a way that started to turn her on. Then she realized something else was happening. Her t-shirt started straining from more than just the size of her boobs. It lifted up some and she felt a draft on her now-swelling belly.

What the...?! Stacey's hands moved to her rapidly ballooning midsection; her own touch stimulating nerves in ways she hadn't imagined possible. She dropped onto her bottom, breasts bouncing and her inflating belly jiggling in a way that nearly made her pass out from the sudden rush of pleasure that came from ingesting all the formula at once. She moaned and rubbed a boob and fully erect nipple with one hand and her bloating stomach with the other. She nearly passed out form the sensations, but finally came to her senses with her enormous belly cradled in her lap, pushing her huge boobs out to the sides. Her t-shirt was too tight, riding up over her belly and under her boobs; she peeled it off over her head, and the sensation of the air hitting her exposed, stretched skin was overwhelming.

Geez, this is messed-up. Some kind of trip... Gotta find out from Erin what this stuff is... Stacey heaved herself up, momentarily distracted by the sensations her body was sending from newly-expanded parts, then she made her way, bouncing and sloshing, to Erin's door and knocked.

"Erin! You up?!"

Still waiting for Kathy to call back, Erin had been napping. She poked her head out of the covers at the sound of Stacey's voice. "Don't come in!" She yelled.

Stacey hollered through the door, "I've gotta ask you about something! Now! Can I come in?"

"NO!" Erin yelled back, Instinctively pulling the covers up around her bloated form. The movement made her breasts jiggle and her belly press against somewhere sensitive, but she tried to ignore it.

"Erin, I've got to come in! It's important and I'm coming in right now!" She opened the door and stepped into the room with a force that shook her belly enough to make her knees feel weak.

Erin stared at Stacey's naked, inflated form filling the doorway. For a moment, she said nothing. The she giggled. And giggled more, and more, breaking into full-on laughter that shook her own ballooned body in ways that made it even harder for her to stop.

"What's so damn funny??" Stacy blurted, hands placed on her hips so that her belly hung lower and her jiggling boobs nearly pulled her down.

Erin stopped to catch her breath. "You... took the... You moron!" She started laughing hysterically again, and dropped the covers she'd been holding up, to reveal her own inflated belly and boobs.

Stacey's eyes widened. "You knew??"

"No, no I didn't," Erin answered. "It's something Kathy made. It's supposed to be a breast enlarger formula. But I took too much and this happened. And it looks like you did too!" She started laughing again, making her belly and breasts shake like a small tidal wave was running through them.

"Great. So now I'm a guinea pig for one of Kathy's science experiments," Stacey huffed. "How does she fix this?"

Erin giggled again. "I don't know."

"WHAT? You don't know?" Stacey looked completely confused. "If you wanna be a blimp-girl, fine. But how do I get back to normal??"

"Well, genius, remember when you took food out of the fridge?" Erin asked.

"Yeah, so what?" Stacey asked.

"You took stuff out and put it on the table. The antidote was one of the things you took out," Erin explained. "And it has to stay cold. So it spoiled."

Stacey thought for a second, and realized Erin was starting to make sense. "That means..."

"That means we're both stuck like this until Kathy can fix us!" Erin pointed at her roommate. And started laughing again.

Stacey flushed and looked down at her swollen self. "I'm a balloon. I'm a freakin' balloon..." And started laughing herself. She turned, a little too fast so her boobs swung and nearly pulled her along with them, then she got her balance back and stomped into her own room, mumbling, "I'm a freaking BALLOON!"

Erin called after her. "Hey! How much did you take?"

"All of it!" Stacey called back.

Erin giggled. "That's how much I had, too, so we're even!"

Stacey flopped on her bed in a heap of jiggling flesh. She fingered one of the rings in her nipples and looked at her image in the mirror on the dresser across from the bed. The bad part is, I could almost get to like this...

*           *           *

The doorbell rang. Erin rolled out of bed and tried to move quickly, still naked since nothing fit, her body bouncing in enticing ways and doing its best to distract her. She looked through the peephole. It was Kathy! She stayed behind the door and opened it for her friend, calling to her, "Get in, quick!"

Kathy stepped in. She was a little shorter than Erin and Stacey, but slightly thicker, with more up top and a backside that filled her stretch jeans nicely. Her strawberry-blond hair was fairly short. "What's so important? I got your call, but I was across town where the cell service sucks..." She stopped talking and gaped as she turned around to face Erin, who was closing the door. "Oh... My... GOD!!!"

Stacey came around the corner, also buck-naked and ballooned out the same as Erin.

Erin pointed to Stacey. "My genius roomie here left the antidote out all night. And then she drank the other half of all the formula. So now what?"

Kathy looked both of the girls up and down. They were... fascinating. "You both drank half of the whole batch? Wow. You should have both wound up with boobs down to your knees. But this... She reached out and touched Erin's soft, round belly. I didn't expect this."

Erin sucked in her breath form the effect of Kathy's touch. She really didn't need the arousal right now. "How soon can you get us more antidote?"

Kathy sighed. "That's... a problem."

"A problem?" Erin asked. "Don't you have more back at the lab?"

Kathy shook her head. "No. I don't. That's why I told you to be careful and keep it cold. It'll take at least 48 hours to make more. And that might be too late."

"Too late? What do you mean too late?" Stacey asked.

Kathy answered, "After 36 hours, the formula you've taken starts to become permanent."

Stacey's hands flew to her belly, eyes wide.

Erin gasped, "Permanent? We'll be permanently stuck like this? I can't go out like this -- I don't even have any clothes that will cover me!"

Kathy shrugged. "I'll have to start right away and make a stronger antidote dose that will hopefully reverse it. I'll see what I can do. I'm really sorry, but I told you not to..."

"I know," Erin said, glaring at Stacey. "Just do your best."

"I will. I promise," Kathy tried to smile, and reached out to hug Erin. "Just stay in, both of you, until I get back." She strayed a little long in the hug, feeling Erin's engorged form against her body. The sensation was... interesting. Then she broke free and let herself out.

Erin flopped onto the couch. Stacey, uninvited, did the same and leaned her naked self up against Erin. "I'm sorry, I had no idea." Stacey reached across to hold Erin's hand, brushing quite intentionally against Erin's quivering breast and belly on the way.

"Knock it off, weirdo," Erin complained.

"Nothing better to do," Stacey said, fondling one of her own giant tits. She rolled off the couch and landed on her belly, balancing on it like she would on an exercise ball. "Hey! Look what I can do!" she giggled.

"Great," Erin said. She turned on the TV to find something to watch, failing to realize that she was absently stroking the curve of her own inflated belly and enjoying it.

*           *           *

Doorbell again.

"I'll see who it is..." Stacey jumped up and headed for the door. She'd quickly adapted to the challenges her oversized state brought, although her movement was still a mesmerizing display of bouncing belly and boobs. She peeked through the peephole, and then reached for the doorknob.

"Hey! Don't..." Erin hissed.

Stacey pulled the door back, which hid her behind it and let the guest in, with Erin in full view of whoever it was.

Jeff stepped in, getting a full-frontal view of Erin on the couch. He grinned. "Wow! You're really liking it!"

"Not... exactly..." Erin answered. "There's been a problem."

Stacey closed the door and moved closer behind Jeff. "I think she means it might've been me."

Jeff turned around to take in the full view of Stacey, naked and inflated just like Erin. He gaped. "You...?"

"There's an antidote. And she left it out of the fridge," Erin said.

"And you never told me anything about it," Stacey argued.

"And you decided to chug all the rest of the formula without even asking how it worked!" Erin shot back.

"Whoa! Girls!" Jeff tried to calm the situation. Being stuck between two attractive women, who both looked like they'd both had a strange accident with a tire pump, was possibly the oddest arousal he'd ever had.

Erin hugged Jeff from behind, pressing her enlarged self against him. "Kathy's working on fixing it."

"What do you do until then?" Jeff asked.

"We stay here," Erin sighed.

Jeff grinned at her.

He really kind of likes me this way... Erin thought. It was fun last night for sure, but...

*           *           *

Two whole days. That was how long it took before Kathy came back with a solution. Jeff had come and gone as usual, and the sex had been great. Erin had to admit that her body really liked its new form. Jeff had even discovered that other people fantasized about it and made erotic artwork and photo-manipulations about it, and Erin had to admit that it was intriguing and even a little hot. But she still wanted her "normal" body back even as she was starting to wonder if non-inflated sex would ever be OK for more than just a quickie.

So now Erin and Stacy sat on the couch while Kathy explained the situation. Jeff was there too; Erin leaned back on him while he tucked his arm under her boobs and stroked her still-sensitive belly. Stacey lounged on the couch, looking at Kathy's slightly thick form, wondering what Kathy might look like if she'd taken the formula herself.

"So here's the deal," Kathy explained. "The effect of the formula you took won't go away unless you re-activate the cells in the body that made it."

"And that means?" Erin asked.

"It will take more of the formula to make your bodies receptive to the antidote." Kathy said.

"Wait, that means we have to take more?" Erin asked anxiously. "But won't we..."

"Get bigger?" Kathy finshed for her. "Yes. You have to let the formula work to re-activate the cells in your body that it changed. Then you can take the antidote and it should get you back to normal."

"How long?" Erin asked.

"A few hours. Not even a day. But we need to get started," Kathy said.

Erin sighed, making her breasts and belly heave, to Jeff's quiet delight. "OK, let's get started."

Stacey just toyed with one of her nipple rings and smiled. "Let's do this."

Kathy handed a vial of red liquid to both girls.

"Just one?" Erin asked. "We took five before."

"It's concentrated," Kathy replied.

"Here goes," Stacey said and downed the contents of hers. Erin followed.

For a moment, nothing happened. Then Erin felt the familiar warmth spread though her chest and belly. The swelling started, slowly, then the intensity of the sensations increased. She felt the beginnings of an orgasm start and she bit her lip as she swelled -- no, inflated -- larger and larger.

Through squinted eyes, Erin watched Stacey slide off the couch so she could lie on the floor, moaning as her boobs ballooned to the former size of her belly, and her belly inflated to twice its former size. And all the while, Erin knew and felt that her own body was doing the same. The orgasm intensified, and she moaned louder, joining vocally with Stacey who was rolling on the floor and groping herself desperately.

Erin barely noticed that Jeff couldn't hold back; he stripped and entered Erin from behind, pumping deep inside her, which she did notice then -- thankfully -- so she could soak in the sensations driving her wild and release it in an orgasm more intense than anything even over the last few days.

Neither of the girls noticed or likely cared that Kathy had her phone out, taking pictures. For science, of course.

*           *           *

Erin panted. It had taken over two hours for the amazing but-not-exactly-wanted euphoria to subside. Even now, every breeze, every touch on her skin threatened to set it off again. She had trouble seeing all of herself with no mirror available, but if Stacey's figure was a mirror of her own, she knew what she looked like. Her breasts had blown up to twin elongated zeppelins, easily three feet from nipples to where they started on her chest. Her nipples were easily an inch long and half an inch thick, on top of aureolas easily a foot across. Both girl's bellies had inflated to the point that the expansion started to wrap around their sides and across their backs into the beginnings of a ball-shape. They were both blown-up globes of soft, bouncy flesh with zeppelin boobs and heads, arms, and legs.

It was the most incredible, mind-blowing sensation Erin had ever known. And terrifying.

Through it all, Kathy kept measuring their body parts and snapping pictures on her phone. Stacey, ever the exhibitionist, practically modeled for the camera. Erin bit her lower lip with every touch, no matter how clinical, to keep the massive arousal from welling up again. Although Jeff wouldn't have minded one bit. And sometimes Kathy was a little... less than clinical.

"Can we...Ohhh..." Erin gasped as Kathy's hand brushed her rock-hard nipple. "...Take the antidote soon?"

Kathy stopped and looked at her watch, her other hand straying across Erin's expansive belly, fingers exploring Erin's navel. "I suppose so." Her gaze loitered across Erin's inflated body, and then Stacey's. "I've got lots of data. I think we can control this in the future."

"You'd better," Erin grimaced, trying to push the pleasure sensations away before they overtook her rational thinking again.

Kathy went to the fridge and pulled out two vials of the brilliant blue-colored antidote.

Erin grabbed it and sucked it down. Stacey dawdled a bit, admiring her blimped-out self for just a moment, then drank it.

Nothing happened for a few seconds, then Erin felt the constant edge of intense arousal start to fade. Her body was visibly reducing in size. She watched across the room as Stacey's form gradually morphed from balloon-girl, pregnant, to plump as her own body did the same. Kathy had her phone out, documenting the transformation in photographic detail.

In a few more minutes, both girls were nearly back to their "normal" selves.

"Looks like everything's OK!" Kathy announced.

Erin sighed. "Thank God that's over. I'm going to get dressed." With her body back to normal, she suddenly felt more self-conscious than she'd been lately. Somehow, that thought was disturbing, but she couldn't decide exactly why, or if it was good or bad.

"I'll see you later to check up," Kathy said as she gathered her things.

"Bye!" Stacey waved almost too cheerfully as Kathy left.

Erin took Jeff's hand. "Let's get some rest."

*           *           *

Two nights later, Stacey was starting her weekend of clubbing again. Dressed in short-shorts and a cropped tank top that was too small even for her relatively petite figure, she drank in the sensation of the beat and the feel of the air on as much skin as she could get away with baring. The inflation accident had left her with a whole new appreciation of her body, and now she felt almost constrained inside her "normal" self. She wanted out, wanted to escape the confines of useless clothing and her small body.

The music and atmosphere gave her a kind of release. She basked in the rhythm and the buzz of a little too much drink, dancing with anyone -- guys or girls, no matter -- and drifted with the feeling until she needed a rest. There were chill-out spaces all around the perimeter of the dance floor; she picked one in the back and leaned back on a pile of cushions and stretched. The drink was making a comfortable warmth spread through her body, and it felt good.

"Daaaamn, lookit that..." she heard a male voice say, and then realized the speaker was pointing not-too-discreetly at her and talking to his buddies. Stacey liked attention, but something seemed suddenly off.

She looked down, and realized that her tank top was stretched much too tightly across her boobs, which were straining above and below the thin fabric. Her nipples and the hoops pierced through then were clearly outlined through the taut fabric, which was stretching more and more.

Oh shi--- Am I...? Stacey thought. Panic struck for a split second, then the warmth welling up in her body pushed it further and further away.

Stacey's boobs swelled, straining the tank top to its limits. Then the sensation in her belly grew. It was ballooning, and there was nothing Stacey could do about it. Her swelling tits were getting painfully restricted by the tank top and by her inflating belly that was pushing them up. She grabbed the sides of the top and ripped it off, letting her boobs flop free as they transformed from round balloons to lengthening zeppelins, while her belly expanded from pregnant, to yoga ball, to big, round balloon.

People stopped and gaped as Stacey's body inflated before their eyes. Stacey let go and let it happen, drinking in the sensations as her skin stretched and her body expanded from scrawny club-rat to floor-clearing balloon-goddess. It was an amazing, all-consuming feeling that swelled like her inflating belly.

Stacey moved and bounced to the beat, and started dancing. Hands reached out and touched her, cameras flashed. She didn't care; she even liked it. Every touch, every move made the sensations inside her grow and wash over her. She danced, hypnotically, lost in the sensations as the crowd watched and touched and danced with her.

Erin and Jeff were enjoying the night out for dinner.

"I'm so glad this week is over," Erin sighed. I'm wiped.

"I know," Jeff said, holding her hand across the table. "But it wasn't all bad." He winked.

Erin fidgeted. "It was weird. I mean -- we had fun. We had a lot of fun. But... I don't know..."

"I'll admit it. I found out it was... I mean you were... really great that way," Jeff said.

Erin raised her eyebrows. "Me. How? Which way? Porn-queen boobs? Preggo and bloated? Blown up like a balloon?"

"Well.." Jeff fumbled. "It's all you... and all good. And really fun..."

"Which way?" Erin insisted. "I mean, I had fun. More than I really want to admit. There. I said it. But how much did it do for you? What was best?"

"Mmmm... I... I think I liked it best when you were... biggest."

"Biggest." Erin repeated, feeling an odd chill run through her body. "That was... so weird. I... guess I liked it? But, like, it was so strange with Stacey and Kathy there. And I was like, totally out of control. It was messing with my head. I was afraid I'd be stuck that way forever."

"But you're not," Jeff said.

"No, no I'm not," Erin agreed. "I mean, we could try it again. Just by ourselves."

Jeff smiled. Maybe a little too eagerly. "Sure. And we'll take it slow. It'll be fun again."

"OK," Erin agreed with a giggle. It felt more exciting than she really wanted to admit to herself. "But I'm getting a mini-fridge and putting it in the bedroom. For the antidote."

"No more mistakes," Jeff agreed, smiling.

They continued their dinner. Erin's mind kept coming back to agreeing to trying more of the breast enlarger -- no -- body inflation formula with Jeff. Thinking about it gave her the oddest tingle. Am I... Are we... really that kinky? Maybe... It would take time to figure out.

Dinner was nearly finished.

"Anything on the menu you want for dessert?" Jeff asked. "Or would you just rather stop for an ice cream on the way home?"

"I'm not sure," Erin answered. Then something felt odd. A tightness around her chest. And around her waist.

Jeff noticed Erin's expression had changed. "Something wrong?"

"I don't know," Erin said. "I just feel... too full. Maybe we should go."

"OK," Jeff shrugged. " No problem."

Erin felt the tightness increasing in her clothes. "Jeff," she whispered. "I think something's wrong."

Jeff looked concerned. "Wrong? How?"

Erin felt warm, and her bra was definitely too tight now. She looked down and saw the fabric of her dress beginning to pull tight between the buttons. "Jeff, I think it's happening again!"

"Happening again? What?" Jeff was confused.

Erin pointed to the front of her dress, where the buttons were clearly starting to strain, and her cleavage was visibly deepening in the neckline. "I think I'm blowing up again!"

"How??" Jeff asked. "You haven't had any of the..."

"No, that's what scares me!" Erin answered. "We need to get out of here!"

Fortunately, the waiter came and delivered the bill at that moment. Jeff offered his card to pay, and the waiter took it back. Erin fidgeted with her clothes, trying to settle herself in the chair so no one would notice, keeping as bland a smile as possible through the ordeal. All the while, she could feel her bra straining to contain the growth, and her belly begin to press into the edge of the table.

The waiter brought the receipt back, and Jeff quickly signed it, then helped Erin up. She stayed slightly bent over and hugged close to Jeff as they hurried out, nonchalantly as possible. She could feel her swelling self rubbing against Jeff and it was already stirring up sensations...

Jeff's car was close, and when he opened the door for her, Erin pushed the passenger seat forward and dived in the back. "Let's go!" If I blow up in the front, you won't have room to drive!"

Realizing what Erin meant, Jeff closed the door and got behind the wheel. He turned around and saw Erin struggling with her too-tight dress in the back seat. The buttons across her bosom gave up all on their own, and she ripped her bra off herself to free her breasts as they ballooned to watermelon-size. With her boobs free of painful confinement, Erin ripped the dress open to release her inflating belly. "Let's get home before I can't fit in the car," she grunted as she tried to get into a comfortable position.

Jeff drove home, bending a few traffic laws but not so much as to attract attention. In the mirror, he could see Erin's body bloating up like a parade balloon inflating. Every bump jostled her soft, bouncy body and made her inhale sharply as the sensations assaulted her. Her hands alternately flailed and rubbed circles on her expanding belly and boobs.

Fortunately, it was dark and quiet when Jeff parked in front of Erin's apartment. No one was around to see as Jeff opened the car door and help his inflated girlfriend squeeze her mostly naked expanse out of the car and up to the apartment door. He helped her squish her way inside and closed the door as she shed the remains of her dress and underclothes.

Erin dropped onto her belly on the floor in the middle of the apartment. She'd inflated to the size she was when Kathy had given her the second, concentrated dose of the formula. As she rested on top of her belly, her knees couldn't quite reach the floor, and her boobs spread out in opposite directions, hanging down along her massive sides but also not touching the floor. She rocked back and forth to roll herself over.

Jeff kneeled down to hold Erin's hand. She pushed it onto one of her hard, straining nipples and put his other hand on the dome of her soft, inflated belly. "Just get your clothes off," Erin panted.

*           *           *

An hour later, Erin had regained her senses enough to have a conversation. "We have to call Kathy. This wasn't supposed to happen," she moaned as she regained rational thought.

"I already called her. She's on her way," Jeff said.

Erin realized she hadn't been thinking clearly. "Oh, crap! Am I turning into some sort of sex starved maniac? What's happening to me?"

"I think it was just too much for you all at once. You'll be fine," Jeff said.

"I hope so." Jeff was probably right. Erin has having a hard time coming to terms with how much she actually enjoyed these changes to her body.

The doorbell rang and Jeff answered it; it was Kathy, who came right in. "I'm sorry, I came right away, what happened?" Then she spotted Erin sitting on the floor in front of the couch, inflated like a giant exercise ball.

Kathy's eyes went wide. "That's not supposed to... What happened?"

"We were having dinner and I started blowing up." Erin said. "I barely got into the car while my clothes still fit."

"That shouldn't be..." Kathy looked panicked. "We re-activated the cells and the formula and the antidote should have flushed it all out."

Erin patted her expanse of belly. "I think there's plenty still in me."

"What about Stacey? Has she had any problems?" Kathy asked. "Where is she, anyway?"

"She went out to the club," Jeff said.

All three of them exchanged uneasy looks.

The sound of someone fumbling with the door focused all their attention on it. The door swung open, revealing a drunk, naked, fully-bloated, maniacally-grinning Stacey. She squeezed her way in, then wobbled into the middle of the room and flopped forward, momentarily bouncing on her inflated belly which made her zeppelin-boobs flop against her sides. "That..." she slurred a bit, "Was incr... incred... was amazing!"

Jeff shut the door as Kathy helped Stacey right herself. "When did this happen? How did you get here?" Kathy asked.

Stacey giggled. "I'd only been there an hour when I started blowing up like a big balloon. Everybody loved it! Everybody danced with me! Then I got too tired and called a car. The driver loved me -- He paid for the ride just for getting a picture with me!"

"I'll bet," Kathy said. "Can you guys look after her? I have to go back to my notes in the lab."

Stacey had rolled her way, drunkenly, over closer to Erin, where she squished her massive self up against Erin's inflated form, and started kissing and rubbing one of Erin's swollen boobs. Erin grimaced half with pleasure, half with resistance.

"I'll take care of them," Jeff said.

"Take video," Kathy suggested. "The internet'll go nuts," she said as she left.

Jeff turned back to the girls, to find Erin half-heartedly trying to fend off Stacey's drunken advances.

"Are you... Mmmmf... Going to do anything?" Erin asked, as she tired to disengage Stacey from sucking on one of her breasts. Which was hard to do when her own nipple was very nearly out of reach...

"Sure," Jeff said. He undressed quickly, revealing how aroused the sight of the inflated girls had made him. "I told Kathy I'd take care of you."

"That wasn't exactly what I had in mind...Mmmmm..." Erin tried and failed to argue as Jeff took one of her nipples into his mouth and lightly sucked and licked it.

Stacey rolled off of Erin to suck on Jeff's rock-hard manhood while she could, before Erin used her massive size to push Stacey aside and let Jeff inside of her from on top. Erin's whole body shook and shimmied with each thrust, and Stacey once again latched onto one of Erin's flailing boobs, helping her get off to a massive orgasm.

Jeff wasn't quite spent, and as soon as he withdrew from Erin, Stacey pounced on him, riding him and nearly smothering him with her swaying tits and belly. Erin dragged herself over behind Jeff, rubbing her belly and breasts on his face while Stacey took him. She tugged on Stacey's nipple rings, keeping the three of them locked together until they were all finished. All three finally collapsed with Jeff snuggled between both of the girl's huge bellies.

*           *           *

The next morning, Jeff was the only one awake to answer the doorbell. He hastily pulled a bathrobe on to see who it was.

Kathy had returned, as promised. She was carrying a cooler with more antidote. She looked around the room at both girls, looking like overstuffed marshmallows, still sound asleep, and smiled.

"I think what happened is that some of the cells in their bodies are still activated for growth, and once they start, they transmit the change to the rest. They'll have to take a dose of the antidote every day for the next month," Kathy explained. "You're very lucky I made enough of the antidote to get started when the mistake first happened. I'll have more made up in a few more days."

Erin stirred and propped herself up, focusing on Kathy. "You here to fix us?"

Kathy kneeled down beside Erin's swollen form and stroked the side of her inflated belly. "You'll be fine," Kathy said, letting her hand stray to the side of Erin's breast. "Take a dose of the antidote each morning, and you'll stay normal-sized. There might be a while where you'll swell up overnight, but it should get better after a while."

Erin nodded, then looked pointedly at what Kathy's hand was doing.

"Oh! Sorry," Kathy giggled. "I didn't realize." She pulled her hand away. She was wearing a short blouse that didn't tuck into her jeans; short enough to expose the tiny bit of soft paunch she always had, which was where her hand unconsciously strayed next.

Stacey woke next, yawning and stretching, which showed off her bloated shape to its best effect and catching Kathy's full attention. Kathy continued to unconsciously fondle her own tummy.

"Hey, Kathy!" Stacey grinned like nothing was even remotely unusual about her waking up inflated. "What an awesome night that was..."

"Well, It will have to be the only one like that for a while unless you want to be a blown-up party doll forever," Kathy told her. "Take one dose of the antidote every morning until I tell you to stop. That should get the rest of the formula out of you."

Stacey made a pouty face for a moment. "OK, I guess you're right. But it is kinda fun..."

Kathy's hand on her stomach quickened its movements, and her thumb, unseen under her blouse, strayed up closer to the underside of one of her breasts. "I'll bet it is, but it can't be practical for getting to your classes and all."

"No, probably not," Stacey sighed, making her body quiver all over.

"All right then, both of you drink up one dose starting this morning, and stay in touch with me. I'll get you through this." Kathy patted Stacey's belly, unconsciously admiring it, and let herself out.

*           *           *

The next week was relatively normal. The girls drank the antidote every morning, and their bodies remained normal-sized. Erin went to her college classes, and Stacey did what she always did, which was randomly sleep in the back of the room or skip altogether because she spent the previous night in front of her webcam teasing random strangers on the internet.

Jeff kept teasing Erin by changing her computer's wallpaper to various drawings and photo-edits he'd found on the internet of inflated women. Erin pretended to be annoyed, but she kept saving the pictures to look at later when Jeff wasn't around. The longer she went without being blown-up, the more she realized she kind of liked it. Enough, maybe, that once her body was back under control, she'd do it again.

A full week later, Erin noticed that her breasts were a bit full when she woke up in the morning. The antidote took care of it, of course. Two more days later, she felt a bit bloated all over in the morning. As she drank down her morning dose of antidote, Stacey walked in, naked as she often did, with a noticeably distended belly and C-cups.

"Stacey, you look... big," Erin observed.

Stacey looked down and patted her slightly swollen tummy and giggled. "Maybe. Didn't Kathy say we might have some effects in the morning?"

"Yeah, but..." Erin felt a twinge of concern.

Kathy dropped off another supply of antidote the next day, and Erin talked to her. "I keep waking up with some of it coming back."

"Give it some time," Kathy told her. "I told you this might happen. This batch should be a little stronger anyway. You'll be fine."

*           *           *

And so it continued. Every morning, the girls found themselves swollen a little bigger, but the antidote got them back to normal size for the day. Then one evening Erin realized she was blowing up even before she went to bed, and she woke up with DDD breasts and a pregnant-looking belly.

She anxiously phoned Kathy, who tried to calm her down. "It's probably just the last stages of the cells changed by the formula, trying to reject the antidote. Take a double dose each morning. I've got enough made to keep you supplied."

And so they switched to twice the dose each morning. It worked for three days, then Erin came home from afternoon classes and heard a squeal from Stacey's room. The door was open, and she looked inside to find Stacey in front of her webcam, inflating uncontrollably as enthusiastic messages flew through the chatbox on the screen.

And suddenly, Erin's clothes were too tight. Her body swelled with a force she'd never felt before, snapping her bra, tearing through her blouse, breasts and belly bursting out and driving her into a mindless orgasm in full view of Stacey's webcam. She collapsed onto the bed alongside Stacey, desperately fingering herself just as Stacey was, both of them swelling up into inflated masses of bellies and boobs while the camshow viewers flooded the chatbox with comments and donations.

Stacey, by some miracle, was the first to regain her senses. She struggled to sit back up, waved to the camera and made sure to show off her inflated profile to its best effect and signed off. She turned to Erin, who was still panting and moaning on the bed. "I guess we'd better call Kathy again."

*           *           *

An hour later, Kathy was sitting in the apartment with the pair of once again very naked and inflated girls.

"I just don't understand. Your bodies are rejecting the antidote no matter how much I try," Kathy said. "I think we're going to have to face it that..."

"We're going to stay this way?" Erin finished. She looked down at her massive belly, rubbed it with both hands, then brought them up to lift and stroke her huge boobs. She dropped them back onto her belly, making her body jiggle, sending the now familiar feelings up her spine and down lower. "Aww, screw it. I'm OK with it. Jeff absolutely loves me like this. And I'm in marketing. Get your formula fixed and I'll help you sell it."

Stacey giggled and fondled one of her two-inch long nipples. At some point she'd switched out her nipple rings to bigger hoops that matched her gigantic tits. "I made fifteen hundred bucks on my camshow after I blew up on it live, with a guest appearance by my roomie there. I'm good."

Kathy stood up to leave. "OK, well, I've got work to do. You girls have fun." She let herself out, with her hand under her blouse again stroking her own soft belly.

Stacey looked over at Erin and patted her rommate's belly, making it slosh and jiggle. "Get some rest, partner, and get ready to blow some more guys' minds on camera. Don't worry, I'll save the recordings so Jeff can watch later."

Erin let the pleasure from Stacey's touch wash over her. "Mmmm... I'm still getting used to this..."

*           *           *

Two weeks later, Kathy was over for dinner.

"So," Stacey said, "We're doing OK. I do a camshow every couple of nights and pull in a few thousand in donations. More when I can get miss modesty over there to join in."

Erin flushed, which spread from her face to her whole naked and inflated body. "I've joined you at least half the time. And I AM having fun. I admit it."

"I might be part of the problem," Jeff said. "I keep taking up Erin's time." He smiled and tugged one of Erin's nipples, making her suck in her breath audibly. "But how's your work going on fixing the formula.?"

"Pretty good, actually," Kathy answered. "And I found a lab student who's interested in it, and she's got some ideas better than mine. We may have a safe formula ready to test in a few months."

"That sounds great!" Erin retrieved her boob from Jeff's distraction.

"Yeah, it's all good," Kathy said. "But I'm kind of burned out on it all. It's good to have an assistant who knows what she's doing so I don't have to do everything myself now. I'm going to try to take a break."

"What're you gonna do?" Stacey asked.

Kathy fished in her purse and pulled out a small drinking flask. "I'm glad you asked that." She opened the flask and gulped down its contents, then stood up.

Legs apart for balance, arms wide, Kathy just stood and waited in front of the confused looks of the girls and Jeff.

Then it happened.

Kathy's top stretched, her plump breasts expanding underneath.

Her soft belly swelled and started to show as her top failed to cover it.

The seams of her top stretched to their limits while her boobs expanded, even as her belly's inflation caught up.

"Oh God, YES!!!" Kathy screamed as she ripped her top away to free her swelling self from the confinement.

Kathy moaned as her boobs blew up to beachballs, then watermelons, then oblong zeppelins to match Erin's and Stacey's. Her belly swelled out and around, bloating up into a ball-shape four feet across.

As her inflation subsided, Kathy panted and caught her breath. "Ohh... Thank God... I've wanted this so bad..." She wobbled as she tried to lift one foot and reach to pull her shorts off, making her body shimmy and bobble. "Somebody help me get rid of these..."

Stacey rolled to her feet and helped Kathy peel her tight yoga shorts off; Kathy leaned on the back of her chair for balance as she got used to how her gigantic boobs and belly moved.

Erin, amazed by what she'd just seen, asked, "Was that...?"

"The old formula, yes," Kathy panted. "It's permanent. I've wanted it since I first saw you blow up, Erin. I've wanted it so bad..."

Erin gulped. "Wow... I'm... glad for you?"

Kathy let Stacey help her lower herself to the floor, and she leaned back into Stacey's belly.

"Mmmm..." Kathy was enjoying every new sensation. "Erin, come over here and touch me. I want to feel you all over my inflated body..."

Erin came over and joined Stacey in hugging and caressing every inch of Kathy's new shape. "Mmmm... I should have done this sooner..." Kathy purred.

Jeff stripped and joined in. He was quickly enveloped by the girls' soft, swollen bodies, exploring every inch of them. Erin was letting her inhibitions loose, Stacey was participating with gusto, and Kathy was doing her best to lose her mind in the sensations. Jiggling, flopping, sloshing boobs and bellies all around. Three inflated balloon girls in one night... and this was probably going to be a nightly occurrence...
