The story could start with the boy and his uncle being fishermen. The pirates, seeing their boat as an easy target, kidnap them. Once kidnapped, the boy and uncle find that the pirates are part of a larger, more sinister group. They have to use their wits to survive among the cruel pirates, all while the pirates are trying to figure out if they can get more profit from them than just stealing their fishing gear.
Maybe a brave sailor who happens to be in the area. He could hear about the kidnapping and decides to take on the pirates to rescue them.
It might involve a character being forcefully taken from a ship at sea by pirates. Then, perhaps the pirates have some sort of plan for this kidnapped person, like using them for hard labor on their ship or trying to get a ransom from their family. And the 'bred' part could imply that the pirates are trying to indoctrinate the kidnapped person into their way of life over time.
Maybe the kidnapped person is actually a long - lost heir to a powerful kingdom, and the pirates plan to ransom them back to that kingdom.

One possible plot could be that a boy is tickled by someone he initially trusts. Then, in a very strange turn of events, he is kidnapped.

As for the urinating part, perhaps the boy is so scared during the kidnapping that he loses control of his bladder.
It could be a young adventurer. This type of character would be full of curiosity and a sense of exploration. Their kidnapping by pirates would be a major setback to their adventure plans, but they would also be quick to look for ways to turn the situation around.
The plot might involve the boy's family and friends desperately searching for him while the kidnappers have their own motives and plans.
Perhaps the kidnapper had a strange quirk where he would tickle the boy, thinking it was some form of odd 'bonding' during the time he held the boy captive.

One plot idea could be that the anime boy is kidnapped by a group who wants to use his special powers for their own evil purposes. The fanfiction could then focus on his friends trying to rescue him.

Or perhaps he's kidnapped by a fan who has an unhealthy obsession and the story could be about his struggle to escape and deal with this extreme situation.
It could be a young sailor who is inexperienced and easy to be targeted by the pirates. Maybe he is on his first long - distance voyage and is caught off guard when the pirates attack.
