[bubblegum inflation, ff, multiple, clean-ish popping]

Penny and her best friend June had spent the afternoon at the mall. June still wanted to shop, but Penny was tired and weary. She sat down on a bench while June ran into another store. Bored, Penny looked around and saw a gumball machine. She shrugged her shoulders and went up to it. However something was amiss. There was no coin slot.

“Excuse me, miss!” Said a friendly voice behind her. “May I interest you in some free samples?”

Penny spun around to see a rather busty woman holding a clipboard. The size of her bosom made Penny blush and she looked away shyly. The woman, sensing the surprise, simply smiled and stepped up to her.

“Those gum balls are part of a new Pop Palace product and we’re doing a little focus testing. If you wouldn’t mind…”

Penny looked back at the gumball machine and then back at the busty woman. She nodded.

“Excellent! Now if you wouldn’t mind getting a gum ball please?”

“How? There’s no coin slot.” Said Penny in bemusement.

“Oh no worries. Because of the focus testing, these gum balls are actually free right now. Just put your hand under the dispenser and one will pop out!”

To Penny’s surprise, the gumball machine did exactly that. She put her hand under the opening and with a metallic clink, a gum ball popped out into her palm. It looked like a pretty standard gumball to her. After shrugging her shoulders she put it in her mouth and began chewing.

“Now then” said the busty woman “This is a new product by Pop Palace. If you don’t mind, I’ll be asking you various questions as you try it out, okay?”

Penny nodded as she chewed.

“Good! Now then, how does it taste?”

Penny thought for a moment. “Very sugary.”

“Okay then” the busty woman jotted something down on her clipboard. “Do you think you’d be able to blow a bubble for me?”

Penny nodded and worked the gum in her mouth a bit before preparing to blow. The woman’s smile grew and she looked intensely at Penny as a small bubble began to form on her lips.

Within a few puffs a nice bubble had grown, about the size of a tennis ball. But that wasn’t the only thing that grew. As Penny had blown, the busty woman let out a slight moan as her already ample bust began to swell up in synch with the bubble. Penny couldn’t believe her eyes and she looked at the much larger woman with surprise.

“Oh… um… this.. mmmm… this new gum has… mmmm… a strange effect on anyone you look at.” Said the woman, breathless and gasping. She reached up and patted her chest, feeling it’s new size. Penny blinked, she didn’t believe that she had just caused that. And what did she mean “anyone you look at?”

Turning away for a second, Penny saw a punkish looking woman working a register in a store across the way. Without realizing what she was doing, she blew into the bubble. Almost in unison the punkish woman’s breasts began to swell up, much to her surprise. She gasped and cupped her chest, and the woman in line stared at her in disbelief. Penny blew two quick puffs into the bubble and watched as the punkish woman gasped and shuddered with each puff, her breasts swelling bigger and bigger.

“The bubble gum affects anyone you look at, and it’s quite an… intense… feeling” said the busty woman with a moan.

Penny then looked at the woman in line and blew into the bubble again. The woman jumped as her chest suddenly swelled up. Both women now examining their new bosoms.

Then an idea came into Penny’s head and she began to blow steadily while starting at the punkish woman. The poor woman’s chest quickly burst out of her uniform. She tried to cup her arms across them to hide them, but they were too big. As the woman leaned over she let out a loud sexual moan. But Penny didn’t stop. She kept blowing. Bigger and bigger her bubble got, and bigger and bigger the punk lady’s breasts got. They were resting on the counter now, her head arched back as she let out louder and louder moans as the pleasure increased inside her.

Then suddenly Penny’s bubble popped. With a KA-SPLOSH! The punk woman exploded into a pile of pink bubble gum goo covering the counter, the cash register, and woman in line. Penny blinked in surprise. She had just… popped someone?

“Oh yes” said the busty woman next to her. “That is an unfortunate side effect. Popped bubbles result in popped people.”

Penny looked at the woman in line and began chewing the gum up again. She started to blow, causing the woman in line to swell up again. Bigger and bigger she got until her breasts were about the size of weather balloons. People stopped to watch as this woman’s chest grew out of control before with another KA-SPLOSH! She exploded into a pile of pink bubblegum goo.

Penny licked the gum off her face. A strange sensation had started to grow inside her as she watched the two women pop. She began chewing again, almost by reflex.

“Now, you need to be careful… the longer you chew, the more arousing the sensations become. And you wouldn’t want to… AH!” The busty woman gasped suddenly as her breasts began to swell up. Penny was blowing a new bubble while starting hungrily at the woman.

“Oh… oh dear… I worried this might happen one day…” Said the busty woman. She dropped her clipboard. She cupped her growing chest and squeeze them tightly, feeling the sexual tingling that flowed through her body. Penny just stared at her and blew, feeling the bubble on her lips growing thinner and more delicate by the second.

“Please… oh god… mmmm… please don’t… pop me!” Said the woman unconvincingly. “Oh… I… I’m… AHH!” She let out a loud moan as her nipples hardened in her palms. Penny kept blowing. “Oh no… oh! I’m so tight! Please… oh! P-pop me! Please pop me! Oh god I can’t stand it anymore! I’m so tight! AHH! PLEASE! POP ME!” She shouted.

Penny obliged.

With a wet KA-SPLOSH! The busty woman exploded into a pile of pink bubblegum goo.

Just at that moment Penny’s friend June walked up.

“Penny? What happened here? What was that?” She said, being careful not to step in the gum that was splatted on the floor.

Penny simply turned around and looked at her friend with a newfound lust. She licked the gum off her face and began chewing intensely. She blew a small bubble and watched as June jumped in surprise, cupping her chest as she felt the sensation growing in them.

“What’s going on? What’s happening?” Asked June in alarm. But Penny wouldn’t say anything. The intense sensation she felt watching those women pop by her doing was growing inside her as well. She just stared and blew a steady stream of air into the bubble.

June began to groan as her chest swelled up, quickly bursting out of her top and exposing her. She moaned loudly as they pressed into her arms, and she bit her lip as she felt her nipples rubbing against her hands as they swelled. Her legs tightened as a strong sexual feeling grew in her. She whined as her chest quickly ballooned up into weather balloons. But still Penny would not stop. Writhing on the floor, fondling herself in her passion, June’s chest just kept growing and growing until a familiar creaking sound was heard.

“Penny! Oh god please! No!” Cried June through her orgasms.

Penny just put her finger to the bubble and with a quick jab… POP!

KA-SPLOSH! June exploded into a pile of pink bubblegum. The orgasmic rush that hit Penny buckled her to her knees. She gasped in surprise. Never in her life did she ever think that making her best friend explode would be so arousing! She fingered herself for a moment before she realized she was still in public and there were definitely on-lookers.

Blushing and embarrassed, Penny retreated to the nearest women’s rest room. Along the way she made four more women blow up and explode with her bubbles. Each time feeling more and more turned on by the sight.

Stumbling into the rest room, her legs weak from the sexual sensations pulsating through her, she put her arms on the sink counter to stabilize herself. She looked up in the mirror and saw her face. She almost didn’t recognize herself as her crazed look of lust stared back at her.

Then she got an idea.

She pursed her lips. Stared straight into her own eyes. And blew.

Almost at once she felt the sexual intensity hit her again as her chest began to swell. She was blowing herself up! Her mind was racing now. She could blow herself up like a bubble! She could pop herself! She NEEDED to pop herself. She WANTED to pop herself.

Against all restraint, Penny forced herself to stare into the mirror. Her fingers slipped between her legs and she began masterbating as she blew into the bubble. Her chest swelled up bigger and bigger and she was forced to back up against a wall to still see her reflection. Her rapid panting caused the bubble to grow faster and faster. The intense orgasm swelled within her and she began to cum. She screamed into the bubble as it grew. The feeling was overwhelming now. It spread through her entire body. She stared at herself in the mirror for the last time. Raising her finger, she pointed it directly at the enormous bubble that was resting on her enormously inflated breasts. She panted into the bubble and then…

KA-SPLOSH!
