Party Store Blowout Janet bustled through the party supply store, tidying, organizing, sweeping, and generally keeping the place in ship-shape order. She needed this job, it was the only way she was going to pay for her student loans at the moment, and she certainly wasn't going to lose it over leaving the place in shambles. The blonde walked over to the balloon aisle, her heels making soft "click" sounds against the floor as she walked. Jan was wearing her favorite tiny skirt, a blue one that barely covered her ample rear. A pair of dark indigo tights rode up her thick legs, shifting a little bit as her thighs brushed together. She loved dressing up, even if she had to wear some silly polo shirt over whatever blouse she’d chosen for the rest of the day. The balloon aisle had been the bane of her existence ever since she started work at the store. The owner had never properly organized all the products, and whenever Janet tried to, it seemed like just after she finished business would pick up, and after, there would be nothing but a jumbled mess of latex and nylon surrounding the massive helium canister that lorded over all the mess. The canister was old, a relic of the elderly owner's youth when she had started the store. Janet had no idea where she'd gotten it, or even why it was designed the way it was. The canister itself was near as tall as Janet was, old and covered in dozens of layers of paint, giving it a speckled and truly ancient look. Instead of a traditional nozzle, though, the canister sported a tube. It was about three feet long, and stretched down to Janet's waist. The owner said that it was so children could fill up the balloons themselves, but from what her employee had observed, they seemed to pop balloons more than they actually finished inflating them. With a sigh and a look at the nearest pile of glistening nylon, Janet set to work organizing the balloons yet again. Unfortunately for her, the pile she'd chosen wasn't the most structurally sound, and the second balloon she pulled out sent the whole thing toppling to the floor. Janet would have growled in frustration, but she saw that underneath there was a large balloon in the shape of a big "21" with a martini glass replacing the one. Jan smiled. Her best friend Kelly's birthday was on Thursday, she would probably really like this… She grabbed the balloon, and placed it over the odd nozzle of the helium canister. Kicking the pile of fallen balloons aside, Janet reached and turned the valve of the canister on. She must've cranked it a little too hard, the balloon went flying off of the nozzle with a loud "flit!" Janet turned to go chase it, but as she did her right foot slipped on one of the fallen balloons. Her arms windmilled, and she fell backwards. Something broke her fall, though, and sent a sharp pain up her ass. She turned to look behind her, but she was stopped by a small... pressure in her gut. She looked down and saw that her belly was getting bigger. It was unnoticeable at first, just a tightening sensation around her midriff, but soon enough, she noticed that the front of her blue polo top was starting to bulge outward, growing bigger and bigger by the second. Janet stared at her growing belly in disbelief. How could this be happening, if she was blowing up like a balloon! She laid a hand on her gut as it bloated, feeling her fingers spread out as the surface underneath them grew and grew. She felt a draft, and noticed that she'd grown so big that her shirt had untucked itself all the way up to her bellybutton. She looked down wide eyed as her innie popped out, making her look heavily pregnant. Her belly wasn't the only thing swelling up. She blushed and gave a little gasp as she felt her legs and ass start to plump and swell under her skirt. Even her pussy was starting to swell, she could feel her labia start to rub against the inside of her panties, the moment of the sensitive flesh tickling her. She could feel her ass cheeks swell in tandem with her vagina, her posterior tightening and growing fatter and thicker with every passing moment. Jan had never had a small ass, it was always fairly large and shapely, if a little bit flabby from her poor college diet. Now, it was taking on the form of two taut balloons stuffed into a too-small skirt, making it ride up, puffy flesh squeezing over the hem of her underwear giving Janet massive pantie lines. She shifted her weight, thighs rubbing together, flesh pushing against flesh almost to the knees. Janet spread her legs to make room for the sheer size of them, and looked behind her. Her eyes widened as she saw that she had fallen back onto the helium tank's hose! It was buried between two monster ass cheeks, the nozzle punching a hole through the fabric of her panties, sticking straight into her ass. Janet reached around and tried to pull it out of her, but it was no use. Even in the little time that it had been stuck in her anus, her butt had tripled its original size, each cheek tightly formed around the hose in her massive rump. Janet gave a high pitched squeak as one of the buttons on her polo popped off, quickly followed by its lower counterpart. Her breasts had inflated in the meantime, changing from soft, pale C cups to big, tight, sensitive mounds that were only barely covered by her shirt, the garment having ridden up all the way past her belly, forming a tight, blue bra around Jan's ballooning tits. She placed a hand on her left breast, feeling how tight it had gotten, and the hard, erect nipple that jutted out like a tiny mountain from the tit. She thanked goodness that she hadn't worn a bra today, her work uniform was already uncomfortably tight around her breasts, and who knew how painful one of her bras would have been. Janet reached up with her hands, wincing at how much they had swollen, each finger like an overstuffed sausage, with her palms fat and dimpled. She grabbed a fistful of her shirt in both hands, and pulled, giving a squeaky sigh of relief as the fabric tore off, releasing her bloated breasts to the chilly air of the store. Each tit bobbed and bounced as they were let free, eventually floating up towards her face, obscuring her view of anything below the two mounds. She didn't have to see below her breasts to know that she was absolutely swollen, though. Every inch of her body had grown sensitive as it stretched. She could feel the lips of her pussy forming a cameltoe around her panties, now so stretched out and consumed by her two ass cheeks that it might as well have been a thong. Her thighs were sticking as far apart as they could without her doing a split, each now the size of a tree trunk if not greater, stretching the fabric of her tights sheer, giving the world a shadowy glimpse of her tight pale skin, legs growing fatter and thicker with every passing second. Jan bit her lip as her substantial waist burst the elastic on her skirt, her favorite article of clothing falling to the floor like a used towel to reveal her two swollen ass cheeks to the world, the only thing shielding them from the outside being her tiny, overstretched panties, now nearly completely consumed by her ass and vagina, doing just about as much to cover her as the shirt she’d just ripped off her breasts. With a loud "POP! POP!" Janet felt her high heels give way. She blushed. Jan had noticed that her feet were inflating, but not that big. She wiggled her toes, all five of them now fat and swollen, stuck to a bloated foot. Jan suddenly noticed that she couldn't touch the ground any more. She kicked her swollen feet the best she could, trying to gain a foothold, but soon enough she could barely move her legs. She was too tight, rounding and bloating, too fat to move anything more than her fingers Janet groaned, making a high pitched noise. Her lips and cheeks had bloated too, making speech difficult. She looked to her side, an effort made difficult by her swollen neck and two ballooning breasts crammed into her face. To her dismay, Jan saw that somehow her body had consumed her arm, only a small lump with a chubby hand sticking out of it remaining from the appendage. The same must have happened with her legs she thought as her over stretched tights and panties peeled off of her and fell to the floor like three parachutes. Now all she could do was float there at the end of the balloon aisle, looking into the pale valley of her fat cleavage as she filled more and more with helium. How much more could she take? Before, she could feel room to swell inside her body, but now there was no room left, only the elasticity of her turgid skin keeping her from exploding… "DING DING!" The doorbell rang. "Customers!" Janet though, her eyes shooting open. With some effort she yelled out "Help me!" the cry for aid reduced to a pitiful squeak from fat pink lips. The balloon woman heard two sets of feet walking towards the isle, and then a gasp. "Look at that..." It was the voice of her friend, Kelly. "Is that what called out?" Kelly's friend Taylor said. "Is it a person?" Janet heard them walking closer, and then a sharp yank in her anus as the nozzle was removed from her. She gave a sigh of relief as the pressure subsided. One of the women grabbed Janice by the foot, pulling her down to the ground. As she was rolled over to face her rescuers, she saw the face of Taylor and Kelly, looking at her with amusement. Kelly's eyes widened and the grin that was spread across her face widened. "Janet, what happened to you!?" Janet tried to reply, but found that her lips were swollen too tight to move. "What do you think happened?" Taylor replied. "This little ditz got a helium tank shoved up her big fat ass, and blew herself up like a balloon!" The tall brunette grabbed a piece of string and walked over to Janet’s bloated rear, wrapping the ribbon tight around a fat big toe. Taylor let Jan go, making the balloon girl wince as the pressure in her toe increased as the rope dug in, turning it red and swelling it a little more. Janet wiggled a bit in distress, kicking her fat feet in protest as her two friends gaped at her swollen form. Both of the women stared up at her from below, taking in her rounded crotch with her swollen, pink pussy front and center. "Look at the size of her..." Kelly said. "I didn't think a pair of tits could get so fucking fat..." "Tits? I'm looking at her pussy, it's damn huge!" Taylor gave Janet's clit a poke, sending a wave of pleasure up Janet's body. "You know, we were coming here to get a birthday balloon for the party on Thursday..." said Kelly. "You wouldn't mind filling that roll, would you Janet?" She asked the bloated girl. "Of course she wouldn't..." Replied Taylor. "Well let's write a message on that bloated gut of hers!" Said Kelly. "I'm thinking 'happy birthday from a big, fat, balloon bitch!'"
