Stanley was walking to the light rail station when he noticed a large crowd gathered outside the convention center. A massive banner above the entrance read "Welcome to Swap Con!" Curious, he stopped in his tracks, watching cosplayers and excited attendees shuffle inside. He had never heard of this convention before, but something about it piqued his interest.

With nothing better to do, he shrugged and stepped inside. The moment he crossed the threshold, a strange sensation washed over him—his vision blurred, and his stomach twisted into knots. His limbs felt like they were stretching and shrinking at the same time, a tingling warmth racing through every nerve in his body. A sharp dizziness overtook him, forcing him to close his eyes as an overwhelming pressure built in his chest and stomach.

Then, snap!

The sensation vanished as quickly as it came. But something was wrong—terribly wrong.

Stanley opened his eyes and immediately felt the difference. His entire body felt heavier, especially around his stomach, thighs, and chest. His clothes no longer fit; instead of his usual outfit, he now wore a snug anime-print T-shirt that barely contained his plump, sagging breasts, and a pair of too-tight leggings that dug into his soft, thick thighs. A lanyard with a convention pass dangled between his cleavage, the name written on it reading: "Stacy."

Confused, he took a step forward—and pffffrrrt!

A loud, wet fart ripped out of him, sending a wave of warmth against his thighs. His eyes widened in horror as the scent quickly followed—a thick, eggy stench that made nearby attendees grimace and step away.

He gasped, but the voice that escaped his lips was high-pitched, nasally, and awkward. His hands shot up to his face, now round and chubby, a slight double chin forming when he tilted his head down. His fingers—shorter and pudgier—prodded at his soft cheeks, his glasses slipping slightly down his nose.

He had swapped bodies!

Frantic, Stanley—or rather, Stacy—turned to the nearest staff member, practically waddling up to them. Every movement caused her body to jiggle uncomfortably, and with each step, another toot slipped out involuntarily. The gas was constant, a humiliating reality of her new form.

"H-Help! I-I think something happened to me!" she stammered, her voice cracking as she tried to adjust to its new tone.

The staffer barely blinked, as if this was a normal occurrence. "Ah, a body swap, huh? Happens all the time at Swap Con," they said with a casual shrug. "Good news is, you can switch back. You just have to find your original body and make physical contact."

Stacy’s heart pounded. "And... what if I can’t find my body?"

The staff member scratched their chin. "Well, if your original body—or the person inside it—leaves the convention, you’ll be stuck like this. Forever."

A cold dread settled into Stacy’s gut. Well, that and gas.

Pfffttttt!

She had to find her body—fast.
