Hump Hump no Mi

I do not own One Piece, it is the property of Oda, it’s creator. This story is purely fan made and is just for fun, not profit. It has no actual connection to any part of the series or it’s creators.

Its short, but still pretty kinky


Summary: Based on a rather funny and erotic sketch comic I found a while ago, Usopp and Chopper are in charge of guarding the ship one day. It’s a rather boring job until Usopp decides to show Chopper his “secret” devil fruit abilities.


--------------------------------------------------

One day, the straw hat crew had decided to make an emergency stop on an island in order to scavenge for food that yet again Luffy had managed to devour an entire month’s worth of meat in just 6 hours over night! Usopp and Chopper had been in place of guarding the Going Merry as Chopper wasn’t exactly known for being a hunter, due to the fact he was a reindeer, and Usopp’s sharp eye sight would make a good lookout for any enemies approaching the island.


The crew had been gone for three hours by now. Luffy was most likely scaring away any potential meat with some shenanigans, Zoro was probably lost as all hell, Sanji was most likely searching for only the best possible samples, Nami was off drawing a map of the island and Robin was scouting for any signs of ruins she could document.


“This is boring…” sighed Usopp as he slumped over, half hanging off the side of the ship, Chopper was busy preparing his medical supplies he had scavenged earlier and just gave a faint nod in agreement. Suddenly, Usopp had an idea as he perked up. It wasn’t uncommon for some of the Straw Hats to fool around when they weren’t kicking the crap out of some super powerful pirate or marine. He had caught several instances at night where he heard Luffy and Nami, although that barely classified as a secret considering Luffy willingly let her borrow his hat when it was practically the death penalty if anybody else even jokingly laid a finger on it. And he could guess that there was something secret going on between Zoro and Sanji, despite the fact they fought practically every chance they got.


“Oi, Chopper!” said Usopp turning to the small hybrid reindeer who looked at him in confusion to see what he wanted. Usopp had a huge grin on his face and with a quick fling of his arms, tore his clothes off in typical anime fashion.

“Did you know that I ate the Hump Hump Fruit and now have super sex powers!?” He asked, standing naked before the reindeer who barely reached his knees in terms of height, yet it was obvious that Chopper was much older than he appeared due to having been born as a regular animal and thus aged faster than humans.


“Wow, really!?” exclaimed Chopper in pure excitement, shocked that Usopp had managed to keep his possession of a Devil Fruit secret for so long, he had never heard a word about it until just now. Chopper watched as Usopp put his hands above his head, spreading them out by about 24 inches away from each other, or 2 feet apart.


“My penis is this big, and I’ve had sex with 3,000 people I am the world’s ultimate lover!” he declared. Despite the fact that Chopper could clearly see that Usopp’s flaccid penis was NOT 2 feet long, but actually more like 4 inches, he still gazed on in amazement, completely believing Usopp’s lies as he was too naive to believe otherwise. Usopp had a reputation as the greatest liar in the world anyways.


“I bet I can be the best lover anybody has every had, even for you.” exclaimed Chopper, boasting his chest out and pointing to the Chopper who’s eyes were glazed over in excitement. Chopper quickly went about stripping naked as well, having only worn his pink top-hat and shorts. Being naked didn’t actually phase him so much due to the fact that when he was a normal reindeer, he walked around naked all the time. Only deciding to wear clothes after eating the Human Human Fruit.


Usopp picked up the small reindeer boy and placed him against the bow of the ship, Chopper already being hard from Usopp’s boasts. Yet while in his small hybrid form, Usopp’s penis was only 3 inches long, even when fully erect, Usopp didn’t mind though as he knew Chopper could change forms if he wanted. Usopp leaned forward and wrapped his puffy lips around Chopper’s deer cock, sucking lightly on it. Not really having much room to bob on it, he decided to pleasure it with his tongue.


Chopper was in bliss, it almost seemed as though Usopp actually was telling the truth for once about his fruit abilities. The doctor panting and whining as Usopp continued to pleasure him, fingering his balls in addition, it didn’t take very long for Chopper to climax as he let out a high pitched squeal and hugged Usopp’s head tightly, cumming in a tiny spurt as Usopp blushed and swallowed it.

“Usopp-san…” moaned Chopper as he attempted to return the favor, placing a phallic object in his mouth with closed eyes and began to bob along it’s length, managing to get a rather amused “Oi!” from Usopp. Chopper opened his eyes to see he was accidentally trying to oral pleasure Usopp’s 6 inch long nose!

Blushing in embarrassment, Chopper decided to try a different approach and activated his devil fruit abilities, changing out of his small hybrid form and into his full human form, going from a small and child-like body into a tall, hulking brute nearly a foot taller than Usopp, yet the sharpshooter didn’t seem to mind the change in size as the two hugged each other and began to tongue wrestle while laying naked on the ship. It almost seemed comical how the skinny and frail looking sharp shooter was currently dominating the muscular doctor, as Usopp began to adjust his position, he was getting ready to properly mount and hump Chopper when suddenly they heard voices off in the distance. It was the rest of the crew returning with the meat they had gone to look for!


“Usopp….” Whispered Chopper as the two of them look at each other in stunned silence, “Can you show me more of your fruit powers later?” Chopper added as he changed back to his hybrid form and the two of them quickly began to fetch their clothes, trying to put them back on before the other crew saw them.


“Of course, as the doctor, you should know about all the crew’s capabilities in case of an emergency!” said Usopp with a grin as they were fully dressed again and pretended to go about their proper duties just as the crew got within sight. It seemed Luffy was once again trying to get into the food while Name and Robin were restraining him, and Zoro was currently having an argument with Sanji over who caught the better meat.
