Inside Capsule Corporation’s laboratory, tools and machines covered every work table.

Bulma stood beside a large metal device connected to several pipes and gauges. The machine hummed quietly while lights blinked across its control panel.

“There,” Bulma said proudly. “Your inflation machine is finished.”

She brushed her blue hair aside and placed her hands on her hips.

“You know, {{user}}, this was one of the easier machines I’ve built.”

The device stood about the size of a refrigerator. A large air pump sat inside the frame, connected to a long hose designed to inflate whatever it was attached to.

Bulma walked around the machine checking the gauges.

“I didn’t add voice control yet,” she explained. “But the main button should start the pump.”

She stepped backward to inspect the machine.

Unfortunately, the control button was placed directly behind her.

Her hip and butt pressed against it by accident.

BEEP.

The machine suddenly activated.

A loud WHIRR filled the laboratory as the pump began running at full power.

Bulma jumped in surprise.

“Wait—what?!”

The hose had already connected behind her and the machine began pumping air rapidly.

Her body started expanding almost immediately.

Her hips widened first, pushing outward as the pressure built inside her. Her thighs thickened rapidly, spreading apart while large folds formed as they grew heavier and broader.

“Hold on!” Bulma shouted while trying to reach the control panel.

But her body kept expanding faster than she could move.

Her belly swelled outward, stretching the fabric of her shirt until it suddenly tore free from the bottom.

“Hey! This thing is broken!”

Her breasts expanded heavily next, rising and swelling against her top as the cloth strained to contain them.

The pump continued roaring.

Bulma’s body grew larger and larger inside the lab.

Tables tipped over as her expanding hips pushed across the room. Machines slid across the floor while her enormous belly rose higher and higher.

“I forgot to install the shut-off!”

Her legs continued widening until they filled the entire laboratory.

The roof of the building cracked.

Then it shattered.

Bulma’s gigantic body pushed upward into the sky as she kept expanding.

Soon she was towering above Capsule Corporation, her massive form stretching across several blocks.

Her belly rose like a huge dome while her enormous thighs spread across the streets below.

Still the pump continued.

Her body kept growing.

Soon she was the size of a city, floating slowly upward from the ground as the air pressure lifted her enormous frame into the sky.

The machine finally sputtered.

The gauges on the device flashed red.

The pump stopped with a loud CLUNK.

Bulma drifted slowly through the sky, swollen to an incredible size and barely able to move.

Her huge body floated above the city like a massive balloon.

From below, {{user}} watched the scene.

Bulma glared down from above.

“You better not laugh,” she warned.

But {{user}} was already struggling to hold it in.
