Usopp had been hoping, praying, wishing. Maybe this time—just maybe—he could return to his human form. He was done with being Nami's pants. The smell was unbearable, and his once-proud existence had become a suffocating, butt-scented prison.

But the curse had other plans.

As he began to feel his body stretch, twist, and change, he thought he was finally breaking free. This was it—he could feel his body reverting, the fabric stretching and snapping back into shape, his limbs reforming.

But something was wrong. Something… smelled… stronger.

As the transformation continued, Usopp's consciousness shrank, and in a desperate rush, he realized what was happening: he was not turning back.

Instead, he had become Nami's thong.

A simple, small piece of cloth now wedged deep between her butt cheeks, clinging to her skin like a permanent attachment.

Nami, oblivious to Usopp's suffering, slipped into her favorite thong with a smirk. It fit snugly, just the way she liked it. The feeling of fabric pressed close to her skin was one she didn't mind—especially with her cheeks shaping it perfectly. The fresh material was soft, yet the scent that began to emanate from her body immediately was… a little more than Usopp had anticipated.

Nami, having just returned from a long day of navigating, settled down at the dinner table, grinning widely. Sanji's feast was laid out before her. He had outdone himself today: grilled octopus, spicy curry, garlic bread, and a side of fried plantains. A full plate, too tempting for her to resist.

She dug in with enthusiasm, talking about the weather and their next destination, but her focus was on the food.

"Sanji, this looks amazing," Nami said, a little too loudly. Her stomach grumbled.

It was time to eat.

Crunch. Chew. Swallow. Another bite. Another grin.

Then, the first sign of trouble.

As Nami settled into her seat, she shifted her weight. Usopp, now trapped between her thick cheeks, felt it instantly. He could feel her entire body tense as she clenched her cheeks slightly.

BBBBBRRRRRTTTT—

The sound came out loud, but the stink was what attacked Usopp's very being.

"Ugh, that one was bad…" Nami said, clearly amused, wiping her mouth as she continued munching on the grilled octopus. "I love spicy food, but it really gets me sometimes."

The scent was overpowering. It burned Usopp's fibers. It was pungent—foul garlic mixed with something far worse—like rotten eggs in a compost heap. He could feel the sourness of the gas fill his every fiber as he was pressed further into her skin, unable to escape.

"God, I think I'm gonna keep eating—just to see if I can top that one," she laughed, her voice dripping with sarcasm and amusement.

As Usopp remained trapped, he could feel every slight movement. Every slight squirm of Nami's body. Her body was releasing gas constantly now, and each silent fart just seemed to build up the already unbearable stench.

PPPBBBBRRRTTTTTT—

A second fart exploded out of her, longer, and wetter. It shot directly into Usopp's form, soaking deep into the fabric. It was wetter this time—slightly humid, like the remnants of a storm cloud, and filled with a deep, earthy musk.

"Whew, that one has a real kick to it," she said, not even looking up from her plate. "It's like a fermented cheese smell, don't you think?"

Usopp's senses were overwhelmed. He couldn't breathe. The stench felt like it had seeped into his very fabric. Every fiber of his being was stained, suffocated by the never-ending odor of Nami's flatulence. He couldn't escape it, couldn't get away from her foulness. It felt like he had swallowed the fart—like he was made of it.

And then, a third one.

PPPPFFFFRRRTTTTSSSSHHHHH—

A slow, bubbling fart that lingered in the air, the warmth soaking straight through the thong Usopp was now made of. He could feel her body shift as she casually adjusted her position in the chair. The cheek-to-cheek movement pushed him deeper into the crevice, increasing the suffocating pressure.

"Ugh, I can't stop farting today," Nami muttered, shaking her head. "These spicy beans are killing me."

She didn't even care. She just kept eating.

Another bite of garlic bread. Another gulp of water. Another mouthful of curry.

And with each bite, the farts kept coming.

BBBBRRRRRRTTTT— Another short one. It sounded like a quick, sharp puff of air—bitter, full of raw onion.

"Damn, I'm really gassy today," Nami said, grinning as she finished her plate. "Looks like the curry went straight through me."

She stood up and stretched, unaware of the ongoing torment she was causing Usopp. Her thick, powerful legs stretched out, shifting her weight, pressing Usopp into her butt harder.

And then, with a deep, long sigh, she let out one last fart.

PPPBBBBBRRRRRRRRRRRRRRRRRTTTTTTSSSSHHHHH

A deep, resounding "toot" that felt like it could have flattened a city.

"Oh god, that was the worst one of the night," Nami laughed. "I swear, I'm going to start keeping a gas mask around."

Usopp felt like he was suffocating in a swamp of rotting food, toxic gases, and the worst farts imaginable. Every time Nami's body shifted, he could taste it—the sourness of her diet, the heat of the curry, and the undeniable flavor of every single fart she released.

Her cheeks were pressed tightly against him now, and the weight of her body made it worse. He was trapped in her fart prison, unable to escape or free himself. He could feel the heat from her skin, her sweat, the odor that seeped deeper into him with every single movement.

It was clear now. Usopp was stuck.

He couldn't fight it anymore. The curse had fully transformed him into a permanent accessory for Nami's most intimate needs. She could feel her farts reverberate through her body, pressing directly into him.

And all Usopp could do was absorb it.

The smell would never go away. The gas would never stop. He would live in a perpetual state of suffering, breathing in, tasting, and feeling every fart Nami ever made.

And Nami?

She couldn't care less. She was just going to keep living her life.

The perfect navigator. The perfect fart queen

End.
