The old machine shop had been vacated a few months ago, a more modern replacement having been built about a block up the road. And when the university's maintenance department gave up their claim to the building, the science department swooped in and planted their flag. Having their experiment labs was nice, but they were too small. This allowed the department to work on larger-scale experiments. Fortunately, the robotics group had finished up their work in the shop on Friday afternoon, leaving the floor cleared and the weekend open for more unofficial activities.
A car trunk creaked open outside, and two dimly lit silhouettes grunted as they lifted large objects out and placed them on handtrucks. One by one, the pair wheeled the objects into the dark building. Finally, the last object was pulled from the vehicle and the trunk groaned closed. The handtruck and its handlers entered the building, and the door locked as they closed it behind them. Flourescent lights far above buzzed to life as a light switch was thrown. Rusted steel rafters and a dirty metal ceiling spanned above the unfurnished concrete floor. Blobs of the occasional oil stain littered the floor.
"What do you think?" Jenny asked.
"You couldn't find something bigger?" April said doubtfully, wiping perspiration from her brow.
"Not without making a reservation with the department. And that wouldn't be a great idea, now would it?"
"No, I suppose not. I'm just concerned about it not being secure, and the size..."
"Look out there," Jenny gestured at a window. Street lamps provided the only illumination of the campus streets and sidewalks. Not a soul presented itself. "It's Friday night. Nobody is going to come here. And the size is fine."
"Whatever," April responded. "Let's just get you hooked up to these tanks. I was hoping to go to some clubs tonight."
With practiced precision, the duo began attaching hoses to the valves of the tanks. All of these hoses terminated at one valve which would control the flow of everything upstream. Snaking out of that valve was a long hose that terminated in a mask for someone's face. With all the equipment connected, Jenny took hold of the mask and walked out to a point roughly in the middle of the room.
"Are you SURE this is place is big enough?" April asked. The last room they tried - over half as big as this - was barely good enough, and that was with only five tanks.
"Yes, just turn it on," Jenny replied impatiently while turning away from April, strapping the mask around her face.
April shrugged and incrementally opened the ten valves all the way. A small, staccato hiss was heard as a hint of the gas escaped from each valve. Once finished with that, April opened the master valve about halfway. Now, instead of the staccato bursts like before, a long, consistent hiss now pervaded the room, like an orchestra conductor drawing out a fermata at the finé of a concerto. Except this final fermata would last for several minutes, whereas by comparison your typical wind instrumentalist would be passed out on the floor after 30 seconds.
Jenny felt the gas rush into the mask through the tube, and drew in gentle breaths as she consumed it. Her chest and stomach rose as each breath was drawn in, then fell as it was expelled. Rise... fall... rise... fall...
Rise... fall... rise... fall... rise... rise... rise...
Jenny giggled to herself as her breasts began to fill up inside her t-shirt, pulling it even tighter than it already had been. As the cotton fibers stretched wider, the lacy designs decorating her brassiere began to show through the fabric. The cursive "Princess" on her shirt began to distort as it was pulled wider. The bottom of the shirt rode up as her stomach also expanded. Her khakis tightened as her butt grew.
April walked over to the window and glanced out at the empty parking lot, save for her car. If any of the professors decided to pay a surprise Friday evening visit, there would be hell to pay. Not only hell, but a good chunk of their paychecks as well.
The button on the khakis broke, relieving some - but not all - of their duress. Jenny's stomach pushed the zipper down as it continued growing, no longer restricted to such a ridiculously small size. The situation was still pretty tight up top as well, the bra not particularly agreeing with the ballooning nature of its residents. The entirety of the shirt was now pulled tightly around Jenny's chest. "Princess" was three feet wide, the sweeping looped curves of the letters dancing about her chest.
A cell phone rattled around on a tabletop. April turned from the window and walked over to pick up her phone. The LCD screen was lit up with a new text message... from Josh! Oh, he was so dreamy! April's pulse quickened as she fumbled with the phone to read the message. He WAS interested in going to dinner sometime!
The pants began to be pushed down by their engorged contents, with robust buttockal cleavage rising out the top like a loaf of bread in an oven. A dainty teal thong circled Jenny's waist, a tiny triangle of fabric perched above her crack before a single string plunged below. Her belly button, as wide as a golf ball, gently inverted. Arms and legs slowly began to puff up, pulling her pants and sleeves tighter still.
Jenny closed her eyes in anticipation, knowing that her favorite part was coming soon.
April labored to reply to Josh's message. Hopefully he was willing to go out tonight. She shouldn't be tied up for too much longer, and then she could go out and stare at his adorable dimple all evening long. And the way one eyebrow was a little higher than the other! Oh, rapture!
Bra clasps snapped behind Jenny as her inflating breasts finally outpaced its capacity. No longer quite so restricted, her breasts swelled again, pulling the shirt up further and revealing the bottoms of her enormous mammaries. Her butt had worked its way free of the pants, the diminuitive lingerie disappearing between the large globes adorning her backside. And now, as her legs swelled, the pants slowly continued their downward trip, steadily revealing more and more of Jenny's fattened legs. In front, Jenny's generous gut met the curves of her plumping thighs at her crotch, the thong marking their intersection point.
And then, Jenny's feet left the ground.
April finished off the text message and held the phone to her chest, hoping against hope that she would have a date tonight. Then she glanced up and noticed her friend and colleague floating in the air. With a nonchalant attitude, she put the phone up and returned to the row of tanks. With a few flicks of her wrist, she fully opened the master valve - just like she had done several times before - and returned to staring at her phone, waiting for the pot to boil over with another text from Josh.
Now a couple feet in the air and still rising, Jenny cooed with delight as she was now being fed twice as much gas. Correspondingly, she began to blow up faster. Her legs began to spread apart as they continued their growth, pushing her pants down past her knees. The shirt finally ripped down the middle and around the sides, severing "Princess" in half and allowing her prodigious breasts to burst into the open air. Determined nipples stood up on the surface of her skin. The tattered shirt and useless bra fluttered down toward the floor and landed unceremoniously in a pile. Jenny laughed happily, always overcome by that same lusty feeling when her boobs explode through her shirt.
Something out of the corner of April's eye caught her attention. Were they headlights? Shit, they were! April immediately began fumbling with the blinds trying to close them, and visually inspected the door from afar to make sure it was locked. As she turned back to the window, she peered around the drawn blinds and found the headlights replaced by a red glow. Brake lights. The car had passed by uneventfully. False alarm. April sighed and regained her composure, reopening the blinds. She refocused her attention on the cell phone, willing Josh to respond. And quick! All this waiting was sooo not cool.
Several feet above, any hints of Jenny's lean figure were rapidly disappearing. Her waistline was already several feet around, complemented by large round breasts on top and a large round butt in back. Her arms stiffened as they swelled up more, her back beginning to flare out behind her. Her legs grew shorter as her groin inflated further, finally catching up to her pants and pushing them down around her ankles before they slipped off her feet completely. The thong finally gave up and broke, dangling for a minute pinched in her rump before also falling to the floor.
April's cell phone lit up again with another text and she jumped exuberantly. She fumbled with the buttons and... Josh could go tonight!!! April bounced up and down uncontrollably, happily clapping her hands. Now what was she in the mood for? Mexican? Barbecue? Italian? Definitely Italian. She promptly started tapping out a query for his interest in eating at Romeo's.
Feet and hands now began to plump up as Jenny entered the final stages of her transfiguration. Flip-flops slipped from between turgid toes and pink painted toenails, once and for all leaving Jenny clad in nothing but her own pneumatic nudity. It was highly unlikely she retained any useful mobility by this point, but it didn't matter. She enjoyed the experience far too much to distract herself by trying to move. Her eyes remain closed, her emotions fixed on the intoxicating sensations of stretching outward inch by inch, foot by foot, as she yearned to blow up even bigger.
The cell phone beeped as April triumphantly sent the text message to Josh. Oh, she was getting excited now! April looked up at the orb-like underside of Jenny's form. Wouldn't be much longer now. Barring an unexpected visit from college faculty, she could leave in just a few minutes and get a generous helping of her hunky date. And as she gazed out the window at the dark campus, she knew that with each passing minute that unexpected visit became more and more unexpected.
Jenny pivoted upside down and twisted in the air as the hose ran out of slack. Even her hands and feet had now flattened against her contours at this point, the tiny arcs of her fingerprints decorating her sides as she steadily swelled larger. She had never gotten this big before. Only her massive bosom and portly posterior remained as outward examples of her sexuality. Her nipples were still stubbornly erect, standing at attention in the centers of pink areolas that stretched outward for several feet.
Josh said yes!!! Delight of delights! He had suggested meeting in 45 minutes. April began assembling a mental list of things to do before the date. Not enough time to shower, but that was ok. How would she do her hair? It would be pushing it to break out the curling iron. Ponytail was too informal. Straight would be fine. What would she wear? Romeo's was a classy place. Blouse and skirt? Nah, not good enough. Oh! Jenny had a great little low-cut black dress that fit April like a glove. She would wear that. Besides, it wasn't like Jenny would be squeezing into a size 4 anytime soon.
Jenny's size began to eclipse the light coming down from the ceiling. Her crotch bumped against a rafter as she reached her upper boundary. Still she fixated on the undying pleasure she was experiencing, listening to the hiss of the gas resonate within her immense body. As she stretched for each extra inch she yearned to grow a hundred more.
Another few moments passed as the blimping young damsel steadily took up more and more space in the vacant workshop. April was checking herself out in her compact, deciding how much blue eyeshadow to apply. She knew Josh wouldn't be able to resist her with the blue eyeshadow. Most guys couldn't. Except for Dave. He didn't like it too much. And Greg. No, Greg wasn't a fan either. And Miles. And Joseph. And Mark. And... oh, never mind. Maybe just a little blue eyeshadow.
Finally, the hissing chorus ceased as the tanks' supply of gas became exhausted.
The ceiling was about twenty feet high, and with Jenny upside down, she almost met the seated April eye to eye.
Jenny opened her eyes at the premature stoppage of the gas. She began saying something to April, but it was muffled by the mask. April reached up and removed the mask from Jenny's head.
"Turn the gas back on!" she squeaked softly. The gas had distorted her voice even more than previous times.
"Sorry, but it's all gone," April shrugged.
"GONE??" she squealed wildly, her brow furrowed. She shook her head, her brown hair and highlights frisking about. "But I wanna be bigger!"
"Well, you know how strict helium rations have been these days."
"Yeah..." A disappointed look crossed Jenny's face.
"What are you going to say when Dr. Ramirez asks you what happened to the science department's entire shipment of helium for this month?"
"I'll think of something."
"Well, I've got a date," April announced. "I'll come check on you tomorrow morning." She stood into a crouch, took hold of Jenny's taut skin, and rolled her backward onto her back. Gigantic breasts and firm nipples swept by overhead until Jenny's form came to an acceptable resting position, propped up against the ceiling by her globular butt. The enormous domed boobs pointed downward at the floor. April reached a hand up and stroked the strained skin. "You've really outdone yourself this time, Jennifer Elaine. Have fun."
A barely audible, high pitched "Bye" emanated from above. April crawled out from beneath the gigantic mass, flipped off the lights, went through the door and locked it behind her.
If only they could've ordered one more tank, Jenny thought. Or two more, or ten more. Anything to get her at least a little bigger. If she could innocently explain away this incident - as she had each time before - then maybe they'd be allocated more tanks next month, and then she'd REALLY have a blast.
"They'll catch on at some point," she reminded herself mentally. "And then I'll really be in hot water."
Still, Jenny smiled and sighed. "This is big enough for now."
