[breast inflation, popping, f/f]

On the advice of her friend, Shante decided to check out the new Pop Palace shoe store that had opened up in the mall recently. She didn’t really need new shoes or anything, she had just been told that it would be an enlightening experience. Whatever that meant!

The store was fairly small all things considered. There were only a few rows of shoes on either side with a register desk at the far back. The middle of the shop was completely open save for a single low bench to sit on. Mirrors that were bent at an angle adorned either side of the bench allowing you to get a good look at your whole body.

There was only one person in the store. A very well endowed employee who perked up immediately when she saw Shante enter. She stepped around the counter and skipped up to her, her enormous chest jiggling like two balloons under her tightly stretched shirt. The sight made Shante blush a bit.

“Hello! My name is Quinn! May I help you?” Said the busty woman in a pleasant voice.

“I’m Shante and I’m just here to try on some shoes” she replied, looking down and trying not to stare at Quinn’s enormous chest.

Quinn just laughed and bent over, giving Shante a good look at her straining top. “Don’t worry, I’ll help you out!” She then put her arm around Shante and held her close, almost squishing Shante into her pillowy bosom.

Together they walked around the walls of the shop. Quinn was explaining each of the different styles and types of shoes, but Shante was having trouble paying attention. Quinn’s enormous chest was mesmerizing and she kept finding herself snuggling into them. Curiously, after a few minutes of walking around the store, Shante could’ve sworn that Quinn’s chest had gotten bigger. But that must have just been her imagination.

After a while Shante managed to focus in on a pair of shoes that appealed to her. They were pink sneakers with teal laces and purple accents. They just felt bubbly and cute to her. Quinn noted the style and said “I’ll be right back” and skipped off to the back room. As she skipped Shante could’ve sworn she heard the sounds of an air pump pumping. But against that must’ve been her imagination.

When Quinn returned a few minutes later Shante was surprised that her already large breasts had almost doubled in size. Quinn was visibly struggling to walk and could barely see over her enormous chest as she carried the shoe box.

“What happened to you!?” Exclaimed Shante as Quinn held the box out to her.

“Oh, this… this is.. mmph… this is normal…”

“It doesn’t look normal!”

Quinn’s eyebrows went up in surprise. “Really? Then why are you here? Isn’t this what you wanted?”

By the puzzled look on Shante’s face Quinn realized that she hadn’t been paying attention as she was explaining the shoes to her earlier. She sighed and smiled with a slight nod to her head.

“This is a pump palace shoe store. Our shoes will blow you up. Literally.” Said Quinn, shaking her enormous billowing chest in Shante’s face. Shante blushed red as she heard a rubbery squeaking coming from Quinn’s breasts as they jiggled gently in the air.

“Blow me up?” Repeated Shante in disbelief.

“Yes, like this!” Said Quinn as she started to strut through the store. With each step she took Shante heard an air pump pressing down and then seconds later Quinn would make a low moaning groan as her chest seemed to inflate bigger and bigger, threatening to rip her shirt apart.

By the time Quinn has returned to Shante’s side, her breasts were the size of two enormous weather balloons and her shirt was stretched so thinly that you could see clearly through it. But that didn’t seem to matter to Quinn who was blushing bright red and panting hard. The sensation of being blown up so big was clearly pleasurable and it took a moment for Quinn’s eyes to focus again.

“Are you okay?” Asked Shante with concern (and arousal). Quinn just moaned back and bit her lip in response.

Not wanting to be rude, Shante took the box of shoes and put them on. They were extremely cute and comfortable. Almost instantly she felt like she was literally walking on air. They were snug but not tight and had just the right amount of firmness to them while still letting her feet breath.

Then she took her first step in them.

Immediately Shante let out a loud gasp as a sudden jolt of pleasure shot through her nipples. She involuntarily cupped her chest and it was clear that her petite breasts had swollen up a little bit. She squished her fingers into her new assets and let out a softer gasp. Her nipples were rock hard already and the sensation was overwhelming her a bit. She took another step. And then another. And then another. Each time she felt her breasts plump up just a tiny bit and hears the distinct sounds of air and a pump. It was almost like her shoes were pumping up her breasts with each step

“Mmmm feels goooood, doesn’t it?” Said Quinn, who has been watching Shante with excitement the whole time. Shante just nodded, words were failing her at the moment.

“You can take those with you if you want, but remember to walk on your tip toes or else…”

Shante snapped back to reality for a second. “What? Tip toes? Why?” She asked.

Quinn moaned as she tried to form words again through the intense pleasure. “Ooofff… you see… the pump… is in…. The heel… so whenever… mmmphhh…. You take… a step… you’ll blow.. blow up…. A bit more…”

“What’s wrong with that?” Asked Shante who was desperately wanting to go for a walk now.

“You… you have to be careful…. If you pump up too much… oh my god…. Ohhhhh…. You’ll…”

“I’ll what?” Asked Shante with bated breath.

“You’ll pop! Like a balloon!”

Something about the breathless way Quinn said that sent a tingle through her body. She could pop? As in explode? If her breasts got too big? Surly that’s impossible.

Quinn seemed to have noticed the slight hint of doubt in Shante’s eyes as she said that and smiled. “Oh boy… I didn’t think… I’d have to… demonstrate this feature… but I guess… if I have to… I’ll do it!”

With that Quinn began to walk towards the back of the shop. Each step causing her to moan as the creaking from her chest grew louder and louder. Her breasts weren’t getting any bigger though, and it became clear that with each step the pressure inside her was reaching a tipping point. Quinn put her fingers in her ears as she took one final step and then…

KABOOM!

Quinn exploded into a shower of rubbery scraps and torn clothing. Her shoes flopped to the ground among her confetti scraps. The echo of her final orgasm ringing through the shop.

Shante gulped, but her mind was already made up. She was keeping her new shoes. What was it Quinn had said? She just has to walk on top toes? That should be easy enough… as long as she didn’t put her full weight on her heels, the pump wouldn’t pump, right?

Shante tried it. She stood up on her tip does and began walking. Sure enough, her breasts did not grow in size and she felt no waves of pleasure. This will be easy!

But as Shante walked around the mall, she soon realize it wasn’t easy at all. Every now and then she would forget to stay on her tip toes, and as a result she would inadvertently pump herself up, causing her to let out lewd gasps and moans. People kept looking at her as she kept making sensual noises as she walked, and eventually she just stopped trying to hide it.

Within minutes her breasts has already swollen up to the size of basketballs. Her shirt was pulled right across her chest, her hard nipples poking through the fabric and giving away how aroused she was. You could see her under boobs as her shirt rose up with each step.

At a certain point she realized that she was not going to be able to make it home. The pressure was growing tighter in her chest and she didn’t want it to end. She decided to instead do a few laps around the mall and really blow herself up! Maybe even literally, just like Quinn had!

After a few more minutes of walking, her breasts had ballooned out to the size of weather balloons. They were enormous but not heavy. They almost took up the entire Mall alleyway now and people were shuffling around her. Some horny people would give her breasts a quick slap as they passed, and each time Shante let out moans of pleasure.

Finally she realized she wouldn’t be able to take any more steps or she might burst. Her mind was a blank now, racked with pleasure too intense to comprehend. Onlookers were whispering about her breasts and she was on the verge of the biggest orgasm of her life. But if she took one more step… she would explode! She knew she would! It was just too intense!

Some women who had been watching her with glee decided to help her out. They came up to her and pushed hard on her chest, forcing Shante to take a step backwards. As the pleasure rocked her mind she let out a scream of pleasure as her foot connected firmly with the ground and one final pump filled her up.

With a thunderous KABOOM! Shante exploded into a pile of rubbery scraps of confetti. Her shirt and pants ripping into shreds and slapping the teenage girls in the face.
