[BE, popping, f/f]

Boom bras (the volatile but free bras from the Pop Palace), were such a big hit that it didn’t take long for the brand to expand into different avenues. One of those areas was in swimwear where the hot new fashion for the beach came in the form of “boom bikinis.”

Much like the boom bras, the boom bikinis were volatile and explosive. Accidentally setting one off triggered a randomized and bright number to display on the waterproof LED coated fabric that would gradually count down until you popped. Given that there were only two possible digits that could be used (one for each cup) the highest the number could go was 99 seconds. Of course most people got far less time before they burst. Additionally the bikinis used a micro filtration system that pumped you up with air (or water if you were submerged) until you exploded, making sure the last few seconds you had were highly enjoyable and fun.

And of course despite their perchance to blow people up, they were free! Nobody is gonna pass up free swimwear in this economy!

One of the most popular beaches on the coast was known as the scrapyard, for obvious reasons. It was a “boom bikini only” beach.

Cynthia was visiting the beach with her best friend Laura. Both of them were wearing boom bikinis. As they entered the beach they saw lots of people engaging in very dangerous activities, such as playing Volleyball. Normally that wouldn’t be so dangerous, but given how temperamental boom bikinis were it didn’t take long for one errant hit of the ball to cause half the players on both teams explode into scraps.

The water was gently rolling onto the sand and every time more and more scraps of popped swimmers would wash up on short. There were women with metal detector-like machines that sensed rubbery scraps and would collect “souvenirs.”

One woman was trying to put lotion on her body when she accidentally slapped her chest a little too hard. A bright 15 lit up across her chest. Cynthia and Laura stopped to watch the poor woman flail about helplessly as the number counted down. Her rapidly inflating chest was drowned out by her moans of pleasure before she ultimately exploded with a hard BANG!

Nearby there were some teenagers playing a game of tag, using small plastic water guns. Whenever someone got hit with the water it caused their breasts to swell up with water until they exploded with a sopping wet KASPLOOSH! It didn’t take long for the game to end with all participants exploded.

Cynthia and Laura found a clearing where no one was around then and planted their towels on the sand.

“Want some suntan lotion?” Asked Laura

“No thank you, I saw what happened to that other girl” said Cynthia warily.

“Your loss!” Said Laura cheerily as she generously applied the lotion to her body.

Cynthia was startled by a loud BANG! behind her. She practically jumped up from her spot and quickly looked around her. An empty shirt and scraps of rubber fluttered to the ground, the result of a poor girl bursting from an errant beachball.

“Oh no!” Said Laura with dismay. Cynthia turns back to look at her friend. A glowing 45 was blazoned across her chest. “That pop startled me and I hit my beasts while lotioning up!” She said, pouting as her breasts began to swell.

“Well, you knew this place was dangerous.” Said Cynthia matter-of-factly. “It was only a matter of time before you blew up!”

“I know but… ooh.. I didn’t… think… mmm… it would be this quick” said Laura, moaning between breaths as her breasts swelled up to beach ball sized as her number counted down. “Mmm…. This feels so good…. Kinda wish I had been jostled earlier…. Oohhhh.”

Cynthia watched in awe as her friend’s chest grew bigger and bigger. The number reached 10 and was still falling. Laura’s growth slowed down and the creaking of her skin indicated she didn’t have long left.

“Oh my god… Cynthia… you gotta… try this! Mmmm I’m gonna…” 5, 4, 3 “I’m gonna..!” 2, 1 “I'm gonna pop! oohhh!!!!” 0… BANG!

Laura exploded into scraps where she sat.

Being the good friend she was, Cynthia picked up the rubber pieces of her former friend and tossed them into the trash nearby. She walked back to her beach towel and layed down alone to get a tan.

After a few minutes of blissful silence she heard the latter of Gert running. She sat up and looked around and saw half a dozen girls running their way towards her. Behind them was a dozen or so beach balls bouncing haphazardly around in the wind.

“Run! The lifeguard forgot to lock up the beach equipment before she exploded!” Cried out one of the girls.

Cynthia got up and started running. On the uneven sand it was hard and the wind was blowing strongly in her direction. One slip or wrong move and she was history!

A bunch of explosions behind her indicated that the beach balls had managed to catch up to some of the girls running and popped them. As she turned around to see who got popped she made the mistake of running into one of those scrap detecting beach combers. SLAM!

Cynthia looked down at her chest as the Number 18 appeared. On the girl she ran into the numbers 07 appeared.

“Hey watch where you’re…. Oooooooohhhh!” Cried out the beach comber as her breasts rapidly inflated. Cynthia let out a moan as her own breasts began to swell up too. The rest of the girls running past them ended up getting hit by beach balls too. All of them in a circle had a bunch of random numbers all counting down.

“Well, I knew this could happen when I came in so I can’t be too mad!” Said one girl as her breasts swelled to the size of weather balloons before she exploded with a BANG!

The beach comber was playing with herself and moaning loudly as her number counted down to 0 and she burst into flesh colored scraps in front of Cynthia.

All around her girls were bursting, and Cynthia was about to be next! She bit her lip as her number reached 5. Her breasts were the size of the beach balls the girls were originally running from. Her eyes rolled back as her number reached 4. She slipped her fingers between her legs as her breasts stopped growing and loud creaking could be heard at 3. Then she opened her mouth and let out a lustful moan as her number reached 2, then 1 then…

“Oh god Laura you were ri-“ BANG!
