Gassy inflation

Lena stood at the testing site, squinting against the late afternoon sun. Her invention—a groundbreaking gas lighter than helium—was ready for its most ambitious test: human flight, using nothing but the body itself. She adjusted the green pole in front of her, which was bolted to the concrete floor. A harness on the pole allowed the attached canister to slide freely up and down a rail, providing access to its valve at the top.

She glanced at herself in the reflective surface of the canister. The bright orange jumpsuit hugged her body snugly, the fabric reinforced in some places to handle the expansion she expected. Or, at least, hoped.

This wasn’t exactly a sanctioned test, but Lena didn’t care. She was going to prove her invention worked.

She pumped up the plug in her ass to keep the hose still and took one last breath before turning the valve. A soft hiss escaped the canister, and Lena braced herself.

At first, nothing happened. Then a gentle pressure bloomed in her abdomen, and her belly began to swell. Slowly at first, then faster. The snug fabric of the jumpsuit shifted as her stomach expanded, pushing against the restraint of the suit. Lena placed a hand on her belly, marveling at the sensation.

Her feet began to lift off the ground.

“It’s working,” she whispered, her voice a mix of awe and disbelief.

The gas kept flowing. Her belly grew larger, rounding out like a balloon as the jumpsuit stretched tighter and tighter across her midsection. She hovered a few inches off the ground, then a few feet. Lena grabbed onto the green pole for balance, feeling the strange tickling warmth in between her legs as her belly expanded even further.

But then, disaster struck.

The canister harness on the pole slid upward, and the canister itself began to rise. Its weight—or lack thereof—made it float higher along the rail.

“Oh no,” she muttered, reaching for the canister.

Her growing belly made it awkward to move, and her jumpsuit was pulled tight around her expanding form, constricting her movements. She grabbed the pole with one hand, trying to steady herself as her stomach continued to inflate. The hissing grew louder, and her belly pressed hard against the seams of the jumpsuit.

Then, with a loud rip, the fabric gave way.

The front of the jumpsuit burst open, and Lena gasped as cool air hit her bare skin. The rest of the jumpsuit tore apart in seconds, unable to contain her massive, balloon-like stomach. Her naked body was left exposed, save for the plug stuck in her ass.

“Damn it!” she shouted, cheeks burning red as she clung to the pole.

Her belly was enormous now, stretched tight and round, nearly doubling the size of her torso. The gas kept flowing, lifting her higher as her grip on the pole tightened. The tingling warmth in between her legs was almost overwhelming, making it hard to concentrate. Her thighs pressed together instinctively as she clung to the pole, trying to fight the distracting sensations.

“Focus, Lena,” she muttered through gritted teeth. “Turn it off!”

The canister floated just out of reach, bobbing slightly as it rose toward the top of the pole. Lena strained her arm, her fingers barely grazing the edge of the valve. Her belly brushed against the pole as it swelled even larger, her skin taut and shiny under the sunlight.

The pressure was almost unbearable. She gritted her teeth, shifting her weight as her body grew lighter, threatening to pull her completely away from the pole. Finally, with a desperate lunge, she grabbed the canister and twisted the valve shut.

The hissing stopped. Right as she came from the pressure. Her figure wobbling in the air as her intense orgasm slowed

For a moment, Lena hung there red faced, panting heavily as she floated in place, her enormous belly buoyant and round. The relief of stopping the flow was quickly replaced by another problem: she was still filled with gas.

“Oh, you’ve got to be kidding me,” she muttered, looking down at her swollen body.

She wrapped her legs around the pole for stability, took a deep breath, and let out a small, controlled release of air as the plug she forgot about popped out of her behind. A loud, unmistakable pffft echoed across the empty test site, and Lena’s face turned crimson.

But it worked.

Her body began to descend slowly as she released more gas, deflating her oversized belly bit by bit. The tingling sensation faded, replaced by a dull ache as her skin returned to its normal size. She finally touched the ground, collapsing onto the concrete in a heap.

Lena lay there for a moment, staring up at the sky, her naked body covered in sweat and streaks of dirt from the pole. She started to laugh—soft at first, then uncontrollably.

“Well,” she said between breaths, “it works.”

She glanced at the remains of her jumpsuit, scattered in shredded pieces around the testing site. With a groan, she sat up and made a mental note: “Design stronger clothing.”

But despite the mishap, she couldn’t help but smile. She had done it. She had floated, unaided, with nothing but her own body.

And next time, she’d make sure to keep a tether on the damn canister.
